[00:28:24] <Jymmm> Tom_itx: area those aquarium lights in your wooden fxture?
[00:28:27] <Jymmm> are
[00:33:11] <Tom_itx> UV lights yes
[00:33:22] <Tom_itx> not for above the aquarium
[00:33:50] <Jymmm> what bulbs did you use?
[00:34:00] <Tom_itx> i think anyway, i got them from a friend and i don't know where he had them
[00:34:16] <Tom_itx> iirc they were 15 or 20w
[00:34:16] <Jymmm> so you havent had to replace them yet?
[00:34:19] <Tom_itx> no
[00:34:23] <Jymmm> k
[00:34:29] <Tom_itx> i don't use them enough
[00:34:44] <Jymmm> heh
[00:34:47] <Tom_itx> i can get a number if you need one

[00:35:18] <Tom_itx> you need something stronger if you need a 3 sec bake
[00:35:26] <Jymmm> Tom_itx: Not yet, I need to find out what wattage I'll need. I know where to get 600W/inch bulbs =)

[00:36:15] <taiden> hello brain trust :)
[00:36:17] <Jymmm> they melt alumnum reflectors if the 5HP blower isn't running too =)
[00:37:12] <taiden> so I've got these cylindrical parts I'm doing
[00:37:18] <taiden> and I need to cut one side, flip, and cut the other
[00:37:45] <taiden> i have the first side down pat but I'm trying to figure out how to locate them accurately for the opposite side
[00:37:47] <Tom_itx> can you say 'rotary axis'?
[00:37:55] <taiden> haha too easy!
[00:38:39] <Tom_itx> we used softjaws on alot of 2nd operation parts and machined the part into the jaw with a little gap between them so that when closed it would clamp the part for the 2nd operation
[00:39:17] <taiden> was that on a rotary axis or a fixture?
[00:39:27] <Tom_itx> 8" kurt vise
[00:39:32] <Tom_itx> err 6 whatever...
[00:39:38] <taiden> I see I see
[00:39:49] <Tom_itx> just machine some soft jaws to fit them
[00:39:57] <Tom_itx> then cut your part into the jaws
[00:40:03] <Tom_itx> op 1
[00:40:13] <Tom_itx> then place it in the finished jaws for op 2
[00:40:23] <taiden> how do you mean 'cut into the jaws'
[00:40:44] <taiden> this is hardwood by the way, should have mentioned that before
[00:40:47] <Tom_itx> cut the profile from operation 1 into the jaws so when you flip the part, it fits the jaws perfectly
[00:41:34] <taiden> so i could cut soft jaws that when closed made a circle shape essentially
[00:41:47] <taiden> and use that to clamp and locate the part
[00:41:52] <taiden> here
[00:41:55] <Tom_itx> well you would need some feature of the part that could locate it
[00:42:17] <Tom_itx> so when located it would be 180 degrees upside down
[00:42:20] <taiden> http://www.youtube.com/watch?v=GlPJPaHbfDg
[00:42:34] <taiden> you can see the first operation finished at 5:15 ish

[00:42:57] <Tom_itx> so i gotta watch a video to see a photo?
[00:43:10] <Tom_itx> what's up with ppl and youtube these days :)
[00:43:17] <taiden> i made it for my father
[00:43:28] <taiden> never bothered to snap pictures of the part
[00:43:30] -!- r00t-Shed [[email protected]] has joined #linuxcnc
[00:43:33] <taiden> :)
[00:44:01] <taiden> that part used to take so long on my little atlas
[00:45:21] <taiden> also you can just jog to 5:15
[00:45:45] <Tom_itx> so what does the 2nd operation need to do? just mill off the bottom with a flycutter or such?
[00:46:18] <taiden> nah it needs to do a pretty complex profile
[00:46:22] <taiden> for aesthetics
[00:46:36] <taiden> so it should be pretty much concentric
[00:46:44] <toastydeath> soft jaws are the second or third most accurate way of holding work in a lathe - far, far more accurate than most people need. it should blend diameters almost seamlessly if you cut the jaws properly
[00:46:45] <Tom_itx> ok, make an insert that fits the inside so when you clamp it, it doesn't break in half
[00:46:50] <taiden> i'd say within 5 thou
[00:46:53] <Tom_itx> then clamp it in the vise like i said
[00:47:04] <toastydeath> soft jaws will be concentric in tenths, not thousanths
[00:47:31] <taiden> but i am such a perfectionist that probably more would go unnoticed
[00:47:33] <toastydeath> put shims between the faces of the jaws and clamp down, then cut the outermost profile into the jaws
[00:47:44] <toastydeath> the shims allow you to preload the jaws
[00:47:50] <Tom_itx> yes
[00:47:55] <Tom_itx> that's the gap i talked about
[00:48:05] <Tom_itx> you don't need alot
[00:48:07] <taiden> oh I see
[00:48:12] <taiden> so it holds them apart
[00:48:13] <toastydeath> ah, i didn't understand what you were referring to, sorry Tom_itx
[00:48:14] <Tom_itx> maybe 1/8" or so
[00:48:25] <toastydeath> taiden, yes - without those shims, two bad things happen
[00:48:28] <taiden> and then when you cut it will close slightly more than the OD
[00:48:36] <Tom_itx> then we 'touched off' on the solid jaw
[00:48:37] <toastydeath> one, the jaw isn't closed and thus isn't accurate as they can flop around
[00:48:43] <Tom_itx> for the x y zero
[00:48:46] <toastydeath> two, you don't have any play in clamping diameter
[00:49:06] <Tom_itx> you do need the insert for the part though or it will crack in half
[00:49:15] <taiden> i could just make jaws out of MDF wouldn't you say?
[00:49:30] <Tom_itx> i don't care what you make them out of
[00:49:31] <toastydeath> most soft jaws will be concentric within .0005
[00:49:46] <Tom_itx> we used aluminum because most of what we cut was aluminum
[00:49:53] <taiden> alright I had another thought that i wanted to run by you two
[00:50:10] <taiden> what if i drilled a 1/4 hole and held the part down with a threaded rod
[00:50:17] <toastydeath> that is, if you keep them clean and undercut the back locating face
[00:50:19] <taiden> orthogonal to the fixture face
[00:50:20] <Tom_itx> that's up to you
[00:50:29] <taiden> and then flipped the part on there
[00:50:37] <Tom_itx> if you have a place on the part you can clamp that doesn't get cut
[00:50:44] <taiden> yes I do
[00:50:55] <taiden> for the jaw method, not so much for the threaded rod idea
[00:50:55] <Tom_itx> you need a couple points to clamp on
[00:51:18] <taiden> that whole outside radius is "finished" in the youtube video
[00:51:19] <Tom_itx> at least
[00:51:32] <taiden> it's slightly elliptical but not by much
[00:51:46] <taiden> maybe 3 thou radius difference
[00:51:57] <taiden> "not by much" for wood haha
[00:52:19] -!- rob_h has quit [Ping timeout: 244 seconds]
[00:54:27] <toastydeath> yes, oversized jaws are preferable to undersized, the jaws will distort to clamp all around the part if the difference is small.
[00:54:27] <toastydeath> also, if it is very oversized, 6 points of contact (on a 3 jaw chuck) is preferable to 3 points of contact
[00:54:27] <toastydeath> (which happens from undersized
[00:54:27] <toastydeath> also, the clamping pressure is relatively continuous for small deviations, so that rings and other thin wall parts suffer virtually no distortion
[00:55:02] <Tom_itx> we had spare lathe jaws too that we would cut to size
[00:55:50] <taiden> lots to think about
[00:56:08] <taiden> any merit in a reverse collet style clamp to fit the inside bore?
[00:57:22] <toastydeath> I always touched off on the part itself by making a facing cut, taking the part out, and measuring it
[00:58:23] <toastydeath> then moving the offset the required amount
[00:58:23] <toastydeath> that way Z0 is always the face of the part and reduces risk of crashing
[00:59:05] -!- taiden has quit [Quit: taiden]
[00:59:21] <toastydeath> i am a big fan of lathe touchoff via cutting and measurment rather than other methods, it's easier to wind up with the first part known good
[00:59:21] <toastydeath> sorry, i'm not sure how emc does xyz on lathes - on most controls it's XZ rather than XY
[00:59:21] <toastydeath> Z being spindle axis
[00:59:21] <toastydeath> X being diameter
[01:02:21] <toastydeath> anything fairly soft
[01:02:21] <toastydeath> that can hold the clamping force
[01:03:20] <toastydeath> http://www.scriblink.com/index.jsp?act=phome&roomid=195&KEY=7A8DB32215CF60DBEBA619928D9372E0
[01:03:20] <toastydeath> that is how i set my coordinate system on lathes
[01:04:21] <Tom_itx> java isn't up to date to view that
[01:04:37] <Tom_itx> but i think we went off the end of the material most of the time
[01:05:20] <toastydeath> also taiden, this is what the ideal soft jaws look like
[01:05:20] <toastydeath> http://www.rockford-industrial.com/Metalworking-Machining-and-CNC-/Rockford-/Airport-Area-/Yelok-8-cnc-lathe-chuck-jaws-aluminum-soft-pie-jaw-provided_image.jpg
[01:06:20] <toastydeath> a set of three, roughly 120 degree wedges
[01:06:20] <toastydeath> doesn't have to be exact, just as long as the part is mostly clamped on
[01:06:27] -!- taiden [[email protected]] has joined #linuxcnc
[01:06:40] <taiden> what i do now is i touch off the fixture as -1.500
[01:06:43] <Tom_itx> i think he missed most of what you said
[01:06:48] <Tom_itx> zlog
[01:06:49] <zlog> Tom_itx: Log stored at

[01:06:51] <taiden> yeah sorry about that battery dropped
[01:06:58] -!- draig [[email protected]] has joined #linuxcnc
[01:07:10] <taiden> and then do a quick face at z=0
[01:07:19] <toastydeath> alu is used for pretty much everything, steel, ti, magnesium
[01:07:19] <toastydeath> it's soft but rigid enough to hold the part accurately
[01:08:26] <taiden> also
[01:08:37] <taiden> i am cutting on a 3 axis router
[01:08:53] <taiden> so i have to come up with a fixture solution
[01:09:13] <Tom_itx> do you have a vise for it?
[01:09:19] <taiden> nothing at the moment
[01:09:22] <taiden> starting from scratch
[01:09:28] <Tom_itx> i see one in your near future
[01:09:32] <taiden> haha
[01:09:46] <taiden> the problem is i can't afford much so i have to get creative to start
[01:10:04] <taiden> right now I have a fixture that holds two blocks of wood, each containing two parts
[01:10:13] <Tom_itx> ok, do the same thing but make a wedge to clamp the 'moving' side of the 'vise'
[01:10:17] <taiden> but now I need to figure out how to do the opposite side
[01:10:19] <toastydeath> taiden, not as accurate as soft jaws
[01:10:20] <Tom_itx> and make a rigid side on your table
[01:10:24] <taiden> lots of good options so far
[01:10:38] <toastydeath> we used that method all the time on milling machines to hold parts, and the tolerances for the fixturing had to be balls accurate to get any sort of repeatability worth mentioning
[01:10:54] <Tom_itx> yup
[01:11:15] <taiden> so it's a right angle fixed piece
[01:11:19] <toastydeath> steel fixtures, reamed pinholes, centerless ground pins
[01:12:00] <taiden> and an angled face on the 'moving' side of the vice
[01:12:10] <taiden> so it sort of pushes it into that right angle?
[01:12:14] <Tom_itx> we used alot of aluminum fixtures since the runs we did weren't gonna be huge

[01:22:33] <toastydeath> you may be interested in that
[01:23:15] <toastydeath> also there is a fork of Qcad,
http://librecad.org/cms/home.html
[01:24:57] <taiden> i checked out freecad
[01:24:58] <Tom_itx> do you use either?
[01:25:09] <taiden> i got really frustrated to be honest after using solidworks
[01:25:35] <toastydeath> i have used qcad/librecad, i am checking out freecad
[01:25:46] <toastydeath> i am used to proe/solidworks as well so that doesn't bode well
[01:25:58] <toastydeath> brb
[01:27:31] <Tom_itx> does either have a cam interface?
[01:29:23] <taiden> i tried heekscad/heekscnc and i couldn't get the cam interface to give me anything good
[01:30:15] <taiden> could be beginners luck though
[01:30:20] <Tom_itx> well mine works but i'm always looking for stuff
[01:30:32] <taiden> i tried to get it to pocket out a circle
[01:30:35] <taiden> and it wanted to cut
[01:30:39] <taiden> 1/32 of the circle
[01:30:40] <taiden> lift
[01:30:44] <taiden> go to the opposite side
[01:30:47] <taiden> cut another portion
[01:30:48] <taiden> lift
[01:30:50] <taiden> etc etc
[01:31:09] <taiden> was about 20 minutes to pocket a 1" OD 0.5" depth circle

[13:45:16] <mrsun> gah freakin one course left so that i can work as en electritian ... the other stuff i could just figure out how it was and make good grades, this one is like a freakin flag pole up my ass
[13:45:46] <mrsun> and it doesnt have anything with thechnical knowledge to do .. "blah start a fake company and calculate blablabla" .....
[13:46:32] <tjb1> engineering economics?
[13:46:51] <tjb1> I would have failed that if the teacher wasnt trying to keep his job :)
[13:46:55] <mrsun> dont know what its called in english
[13:47:18] <mrsun> budgets and reports and shit...
[13:47:42] <mrsun> give me an electronics project i will figure it out, give me an engineering project ill build it ... give me an assignment like this and im totaly blank ...
[13:47:42] <tjb1> Sounds like it...
[13:47:55] <tjb1> Calculus formulas for all the garbage?
[13:48:05] <mrsun> dont know
[13:48:08] <mrsun> very little info
[13:48:21] <mrsun> and they seem to just expect you to know what to do
[13:48:31] <tjb1> I like when the teachers make their own book to make it "cheaper"
[13:48:34] <mrsun> if the "teacher" was here i would kick him in the balls to kingdom comes :/
[13:49:03] <mrsun> i did not make this course in highschool or anything cause my mind just cant process this shit
[13:49:27] <tjb1> Yeah I about failed it but the final paper kept me in
[13:49:51] <mrsun> and dont know anyone that can help me :/
[13:49:56] <tjb1> No one at the school could help, the tutoring center didnt know what the hell it was and the online tutoring was trying to walk me through the whole damn thing without telling me anything
[13:50:45] <tjb1> And I certainly wasnt learning anything from the teacher

[13:53:56] <mrsun> electronics is easy
[13:54:04] <tjb1> Bs it is
[13:54:14] <mrsun> havent read a single page int eh books and wrote almost max score on all tests in those parts
[13:54:23] <mrsun> but when it comes to budgets and shit im totaly lost

[13:56:22] <tjb1> He only takes 12 credits a semester
[13:56:23] <mrsun> even worse is in "real" schools where they try and force you against your will to talk infront of alot of people
[13:56:51] <mrsun> "if you dont you do not pass" ... right
[13:56:53] <mrsun> assholes
[13:56:59] <tjb1> Ive put off a speech class for 4 semesters now
[13:57:10] <mrsun> if you dont jump of a cliff i will kill you is about what they are saying
[13:57:22] <tjb1> Its not that bad lol

[13:57:28] <mrsun> when you panic
[13:57:30] <mrsun> from it
[13:57:44] <tjb1> I used to hate public speaking but I have slowly done enough of it that it isnt too bad

[14:07:59] <tjb1> You know if fedex would stop fucking around with my package...I might be able to get something done
[14:08:33] <tjb1> Im just gonna start flying to places, picking stuff up and flying it back home with me

[14:10:58] <Jymmm> What do you guys expect? You do live in the middle of nowhere.
[14:11:16] <tjb1> I picked USPS because I thought it would be cheaper
[14:11:26] <tjb1> But Im not sure how the mail woman is going to deliver something 6ft long

[14:13:01] <tjb1> All the boxes are a stupid size though
[14:13:07] <Jymmm> then up to 70lbs for $11
[14:13:13] <tjb1> like 20x30x.5
[14:13:26] <Jymmm> lol, of course

[14:16:44] <tjb1> I love it when a truck comes into work like 4-5 hours late and then the guy bitches because we dont have him done in 5 minutes
[14:17:03] <pcw_home> Its 1/2 to 1/3 UPS/FDX rates for international
[14:17:50] <tjb1> Wednesday, UPS Freight came in 5 hours late and then bitches because it wasnt at the dock waiting to be put on the truck and then called his supervisor saying this was suppose to be ready at 9am and it wasnt being loaded
[14:18:26] <tjb1> Was about to tell the overpaid prick to piss off
[14:19:23] <pcw_home> just last month we though UPS lost a packages because they could not find it ($21,000)
[14:19:25] <pcw_home> Luckily they just forgot? to scan it
[14:19:52] <Jymmm> pcw_home: insured?
[14:20:06] <tjb1> I sent a package back to a guy on ebay, had "Delivery Confirmation" because USPS doesnt offer tracking
[14:20:27] <pcw_home> Yes but all that means is a lengthy fight
[14:20:30] <tjb1> Never showed up on the "delivery confirmation" number, guy never got it, never got the acceptance scan...
[14:20:57] <tjb1> I think someone at the post office pocketed my package :P

[14:25:45] <pcw_home> We found a Fedex packages on our street a year or so ago, obviously fell out of a truck
[14:25:47] <pcw_home> (looked to be prescription drugs for someone a mile away or so, so we just delivered it ourselves)
[14:27:04] <tjb1> The UPS driver for my house is pretty decent
[14:27:19] <tjb1> Fedex never comes here and if they do its always a different vehicle/person
[14:28:37] <pcw_home> Yeah we've had really good UPS and FEDEX drivers at work and they are the same for years
[14:28:45] <Jymmm> Hell, if I was delivering to you, I'd run the package over a few times first!
[14:29:18] <tjb1> You know Jymmm, most people that live out here own a few guns :P
[14:29:31] <pcw_home> We do get those "tenderized" packages sometimes

[14:29:53] <Jymmm> tjb1: so do delivery drivers =)
[14:30:16] <tjb1> We got a returned package at work, they returned a 8"x8"x4" box on Conway!

[14:32:56] <tjb1> What if they just drop it off and leave JT-Shop
[14:33:03] <pcw_home> Yeah that the best (feedback!)
[14:33:15] <JT-Shop> the USPS guy won't even get out of his car to deliver a package, he just honks the horn
[14:33:31] <Jymmm> lol
[14:33:32] <JT-Shop> I call them up and say come and get it the package is damaged
[14:33:37] <jdh> mine just sticks notes in teh mailbox saying "you weren't here"
[14:35:46] <pcw_home> Our mail person is good but the annoying thing about USPS is that you cant
[14:35:48] <pcw_home> send to some countries without bringing the package to the post office
[14:35:50] <pcw_home> (Russia for instance, dont they know the cold war is over?)
[14:36:47] <Jymmm> pcw_home: You can, if you have an online account.
[14:37:12] <pcw_home> Nope
[14:37:30] <Jymmm> pcw_home: Not a stamps.com account, but a Usps.com account
[14:37:41] <pcw_home> we do still no
[14:38:29] <pcw_home> most countries are OK

[15:31:15] <Jymmm> heat
[15:31:35] <Jymmm> too much heat and risk it cracking.
[15:31:44] <tjb1> Well in about 3 hours the house will be about 85 inside :)
[15:31:47] <jdh> it drys faster if you watch it.
[15:31:59] <tjb1> I am so tired of doing drywall
[15:32:25] <jdh> would you rather be laying block?
[15:32:33] <tjb1> Probablu
[15:32:37] <tjb1> Probably...
[15:32:38] <Gevallen_Engel> or sod busting haha
[15:32:44] <Gevallen_Engel> thats the worst
[15:32:54] <tjb1> Id rather be putting my plasma table together
[15:33:52] <Gevallen_Engel> same really :\
[15:34:20] <tjb1> I think tomorrow we are going to a flea market, then putting the hardibacker down on the floor
[15:34:33] <tjb1> Sunday or next week will start the cabinets
[15:34:42] <Gevallen_Engel> as for drywall,
http://www.bigjacktools.com/images/dws2300f.JPG a crew had a couple of these at a big job I was visiting, took just the two of them a couple of days to do the whole place
[15:35:11] <tjb1> I wish I had one of them
[15:35:31] <tjb1> They were probably using mud that drive in an hour too
[15:35:35] <Gevallen_Engel> They seem affordable now, if I ever have at the walls in this place I'd grab one for sure
[15:35:36] <tjb1> dried...
[15:35:52] <tjb1> This crap takes like 24 hours to dry
[15:36:29] <jdh> what's the rush
[15:36:53] <tjb1> Been working on the drywall like a month now
[15:37:16] <tjb1> Only really work on it Fri-Sat-Sun
[15:39:22] <Loetmichel> re @ home

[15:59:19] <tjb1> Do items from the solidworks toolbox have a mating property?
[16:01:48] <jdh> most computer objects and many computers users are not subject to mating.
[16:02:19] <tjb1> :/
[16:02:36] <syyl> Jymmm?
[16:02:44] <syyl> you asked me yesterday something?
[16:02:50] <jdh> a prime example
[16:02:52] <syyl> but i wasnt here
[16:03:27] <tjb1> jdh: do you know what I mean?
[16:03:48] <jdh> no, but I do amuse myself.
[16:07:59] <tjb1> I guess you havent used Solidworks then
[16:08:08] <jthornton> tjb1, in an assembly you can mate
[16:08:09] <jdh> can't afford it.
[16:08:28] <tjb1> Do the fasteners have mating properties or just looks?
[16:09:43] <jthornton> any solidworks part can be mated in an assembly, you just have to define the mates you want in the assembly
[16:10:11] <jthornton> click on the part surface or feature and the paperclip symbol is mate
[16:10:21] -!- syyl_ws [[email protected]] has joined #linuxcnc
[16:10:38] <jthornton> then click on the second surface or feature and pick the type of mate you want
[16:11:29] <tjb1> nonono....do the fasteners actually mate parts? I know how to mate just not sure if the fastener does mating also
[16:12:01] <jthornton> I'm sure I don't understand your question now
[16:12:40] <tjb1> Will a fastener in solidworks lock 2 pieces together like a coincident(for example) mate would?
[16:13:15] <jthornton> afaik only if you define the mate in the assembly
[16:13:46] <jthornton> I've never used sw fasteners, I always use mcmaster carr's 3-d models
[16:13:51] <tjb1> So a fastener will lock to the piece you put it on but it doesnt lock the piece its on to the piece it extends into unless you mate it manually
[16:14:23] <jthornton> where are you getting the fastener?
[16:14:35] <jthornton> I have SW open on the next computer
[16:14:39] <tjb1> The toolbox
[16:14:51] <jthornton> with an assembly file open?

[16:17:11] <IchGuckLive> Hi all
[16:17:16] <jthornton> just reading the tutorial and I assume the tool box just creates a part and you have to define the mates like any other part unless you have smart mates on

[16:18:00] <tjb1> Well the smart fastener gave me a bunch of mating errors but pulling from the toolbox manually doesnt

[16:18:37] <jthornton> I prefer to define my mates that way I know what I have
[16:19:10] <jdh> good for gender preferences.
[16:19:23] <IchGuckLive> tjb1: you can preset standard cam systems
[16:19:36] <Tom_itx> jthornton what ver solidworks are you using?

[16:22:27] <tjb1> I like it
[16:22:46] <tjb1> Hopefully I will learn some more advanced mates and testing at school this semester

[16:24:07] <Tom_itx> no 'good' cad cam package will be cheap
[16:24:50] <IchGuckLive> Tom_itx: it's up what you need
[16:25:18] <IchGuckLive> awalli here has a very good strategie to be milling
[16:25:36] <Tom_itx> i don't 'need' any really i have a cad cam package, it's just showing it's age
[16:26:59] <tjb1> Get Mastercam X6 :)
[16:27:07] <Tom_itx> i own smartcam already
[16:27:18] <IchGuckLive> prise for X6 is at 6k EUR
[16:27:28] <Tom_itx> yes
[16:27:29] <IchGuckLive> http://mechmo.de/bilder_css/trafalgar_st.jpg todays work
[16:27:55] <Tom_itx> i gave around 6k or more for mine a few years ago
[16:28:22] <tjb1> Next summer will be X7
[16:28:55] <IchGuckLive> im on Proe its packed at 4.900 including 2 post for NC
[16:28:57] <Tom_itx> this is the product today:
http://www.smartcamcnc.com/
[16:29:18] <Tom_itx> IchGuckLive you have to buy the individual posts?
[16:29:34] <Tom_itx> that's the nice thing about smartcam, you can make your own or mod any that are supplied
[16:29:36] <tjb1> Only as smart as the user
[16:29:48] <tjb1> Ive modded a Mastercam post for a wire edm...never again
[16:30:18] <Tom_itx> smartcam was easier in that regard to mastercam
[16:30:23] <IchGuckLive> Tom_itx: you can do that 2 at NC but with all the complex operations available to the post trancmitter its a good way to do that
[16:32:20] <Tom_itx> i modded my current sherline one for linuxcnc recently. there were only minor changes to make
[16:32:22] <jdh> I see no pricing for smartcamcnc
[16:32:29] <tjb1> I resorted to commenting out large sections and posting code to see what changed
[16:32:39] <Tom_itx> jdh, it's in the 6-8k range
[16:32:49] <Tom_itx> depending on what you buy or need
[16:32:50] <tjb1> Then narrowing down each piece of code in the post script to figure it out
[16:33:01] <Tom_itx> you can get 2 or 3 different mill packages
[16:33:04] <Tom_itx> lathe is separate
[16:33:34] <IchGuckLive> Tom_itx: what is the price for this full smartcam version
[16:33:49] <Tom_itx> there's production milling, advanced milling and freeform milling
[16:33:51] <Tom_itx> i have freeform
[16:34:02] <Tom_itx> IchGuckLive, i'm not sure nowdays
[16:34:23] <Tom_itx> same goes with the lathe packages i believe
[16:34:40] <Tom_itx> their iges translator was pretty good at the time
[16:34:41] <IchGuckLive> cant find any pricing
[16:34:49] <jdh> http://www.webersys.com/ anyone tried this?
[16:34:54] <Tom_itx> you won't, you'll have to contact them probably
[16:35:05] <tjb1> jthornton: You know when doing a width mate how you have to select two different areas
[16:35:17] <tjb1> Is there a key to switch between the two sections?
[16:35:22] <IchGuckLive> Rhino is for small companys a good looking thing
[16:35:47] <tjb1> To switch between "Width Selections" and "Tab Selections"

[17:05:07] <IchGuckLive> tjb1: im not looking for the column itself only for the decoration
[17:06:27] <jthornton> tjb1, start turning off the broken/over defined mates
[17:06:38] <tjb1> That had some names, dont know if they are used
[17:06:49] <jthornton> turn off = suppress
[17:06:51] <tjb1> I found it jthornton, a bolt I added messed the whole thing up
[17:07:04] <tjb1> Is there a way to convert an assembly into a solid part?
[17:07:36] <jthornton> export might do that depending on what format you export to
[17:08:16] <jthornton> but I've never had the need to do that so the above was a WAG
[17:08:47] <IchGuckLive> plasterer is this people that make things for rooms out of sand
[17:13:36] <tjb1> Copy with mates is pretty slow
[17:20:27] <Tom_itx> IchGuckLive i've seen them made but i don't know what they're called

[20:06:17] <JT-Shop> what do you mean by "start slowly"?
[20:06:45] <xlizard> acceleration of the motor
[20:07:15] <JT-Shop> the max acceleration setting for the axis?
[20:07:15] <xlizard> if you have sound on you will hear it ...
[20:08:01] <xlizard> yes
[20:08:43] <JT-Shop> so if you set the max acceleration for that axis in the ini file lower the motor does not run?
[20:09:54] <skunkworks> sounds like resonence..
[20:10:05] <xlizard> it begins to turn but than it tears off
[20:10:28] <skunkworks> are you runing any microstepping?
[20:11:16] * JT-Shop hands off to Sam :-)
[20:11:34] <skunkworks> heh
[20:11:40] <xlizard> yes, ... microstepping of 2 .... but changing it makes no difference ;(
[20:12:06] <skunkworks> what does 2 mean? 400 steps per rev?
[20:12:44] <Jymmm> half step
[20:13:28] <xlizard> divided by 2 ... so yes, half step ;)
[20:13:53] <xlizard> and, 400/rev is correct
[20:14:13] <skunkworks> Can you go any higher? like 4 or 8?
[20:14:25] <xlizard> first i got a cheap china driver board with tb6560 drivers ... there i tried to change the microsteppings. than i build a simple driver with standard l297/l298 .... but the same
[20:15:36] * JT-Shop still waits for an answer to my question
[20:15:57] <Jymmm> 42
[20:16:07] <xlizard> than i thought ... ok, i have the cable, and i whe the motor, thats a LC ... so i disassembled it and connected the motor directly ... also no difference
[20:17:00] <xlizard> JT-Shop: sorry? did a missed a question?
[20:18:08] <xlizard> btw, i have this problem on all 3 axis ...
[20:20:30] <skunkworks> resonence, Realtime delays, or step timing.. (those are my guesses)
[20:20:54] <xlizard> resonence of that?
[20:20:55] <mrsun_> hmm, time to start building my pcb prototyper soon maybe =)
[20:21:01] <mrsun_> got an urge
[20:23:44] <xlizard> sorry, resonence of what?
[20:24:13] <xlizard> hrrsnn, resonance
[20:25:10] <skunkworks> stepping motors at certain rpm go through a resonence that is worse the lower the steps per rev.
[20:25:29] <skunkworks> they more times then not - stall when they hit the effected rpm
[20:25:53] <JT-Shop> <JT-Shop> so if you set the max acceleration for that axis in the ini file lower the motor does not run?
[20:26:02] <skunkworks> when you slowed down the accelleration - the stepping motors stayed in the resonence area long enough to stall.
[20:26:08] <skunkworks> (imho)
[20:26:38] <JT-Shop> sounds plausable to me
[20:27:29] <skunkworks> I would try atleast 1000 steps per rev..

[21:52:39] <taiden> first part i tested i crashed my end mill right into the rod
[21:52:49] <taiden> that'll wake you up
[21:53:12] <Tom_itx> forgot to raize the z clear to acomodate fixtures ehh?
[21:53:20] <taiden> haha not even
[21:53:32] <taiden> with 0,0 being the center of the part
[21:53:41] <taiden> i went to -1,0
[21:53:47] <taiden> then called a subroutine that starts cutting at 1,0
[21:53:50] <taiden> needless to say
[21:53:51] <taiden> ...
[21:54:04] <taiden> RRRRGRRRrgrggrgrgGRGRGRGG!!!
[21:54:05] <archivist> learning the pitfalls...part of the fun
[21:54:49] <archivist> testing first by cutting air helpw
[21:54:54] <archivist> helps
[21:55:09] <taiden> yeah… i got one step ahead of myself apparently
[21:55:56] <taiden> so now i get to figure out how to make a clamp on the cheap for my softjaws
[21:56:07] <taiden> i was all gung ho about the threaded rod.. could have fit 12 parts on one fixture
[21:57:49] <taiden> getting 2 done right is better than getting 12 done wrong, so ..
[22:00:42] <Gevallen_Engel> sounds like were in the same boat taiden, good luck with yours
[22:00:54] <taiden> whats happening on your end?
[22:04:30] <PCW> that's a little private sir!
[22:05:43] <Gevallen_Engel> Just been trying to get past the learning part haha
[22:05:57] <Gevallen_Engel> and repurposing equipment thats been fighting me
[22:12:37] <taiden> yep...
[22:19:13] <Jymmm> Tom_itx: Just curious... did you ever take apart one of those toaster oven heating elements? Do you think one could be made shorter by chance?
[22:21:04] -!- morfic has quit [Remote host closed the connection]
[22:21:22] <Tom_itx> never did
[22:21:39] <Tom_itx> i doubt you could shorten it
[22:21:40] <Jymmm> Tom_itx: Does it look like it might be possible?
[22:21:44] <Jymmm> ok, thanks
[22:22:01] <Jymmm> Tom_itx: I didn't think it would be, but had to ask =)
[22:22:05] <Tom_itx> think stove element
[22:22:50] <Jymmm> Tom_itx: Yeah, just having a bitch of a time "tensioning" the nichrome strip atm
[22:23:14] <Jymmm> too much residual heat build up and such a small area to work with

[23:12:09] <Tom_itx> halogen
[23:12:33] <Jymmm> Tom_itx: way too physically large; using to heat seal packaging.

[23:57:16] <Gevallen_Engel> do they sell replacement elements for larger commercial units?
[23:57:55] <Jymmm> sure
[23:58:39] <Jymmm> the element isn't the issue; it's *tensioning* it that is =)
[23:58:54] <Jymmm> (for this application that is)
