[00:03:48] <tjtr33> chopper79, if i read correctly, the logic is to inhibit the leading joint when it hits the switch, but allow the 2nd joint to catch up, till both are 'just' at the trip points
[00:06:21] <tjtr33> the same logic might be done by incrementally moving a small unit of distance ( not a step, but a small unit of measurable distance ) in a loop till 1st then 2nd are at the switch points
[00:06:59] <tjtr33> then back 'em off and repeat with smaller distances, then set machine 0
[00:07:45] <tjtr33> ( measure twice, zero once :)

[00:11:27] <tjtr33> you wont make it work with the same nets and comps, you will make it work with same idea. an 'event' of the 1st swx change will inhibit the 1st joints motion, yet allow the 2nd join to seek its switch
[00:11:41] <tjtr33> same idea, different nets and comps

[00:18:03] <chopper79> tjtr33.... You did read that correctly.
[00:20:10] <Jymmm> JT-Shop: I don't see where the cnc attachment is for your log splitter? No sense and detect potantial canidates, laser guided splittting for the maximum yield, the robotic arm that picks up and un/loads the splitter?

[00:30:44] <Tom_itx> JT-Shop, how's your splitter coming?
[00:30:56] <Tom_itx> JT-Shop, are you getting any weather yet?
[00:31:13] <Tom_itx> we're supposed to get a big winter storm starting tomorrow
[00:31:26] <JT-Shop> not yet

[00:42:08] <Jymmm> no way thats real
[00:42:15] <JT-Shop> yea
[00:42:23] <tjtr33> the ax is 'flicked' , thats why it looks as if she slapped it sometimes
[00:42:44] <Jymmm> crazyglued or something
[00:42:48] <JT-Shop> there is two ways to split with a double bit axe, the flick or the angle
[00:43:12] <JT-Shop> straight grain wood splits easy if you know how
[00:43:27] <Jymmm> and seasoned for 5 years =)
[00:43:42] <JT-Shop> if you watch the axe it is horz at the end
[00:44:09] <Jymmm> I saw that, that's what made me think it's fake
[00:45:25] <JT-Shop> no trick it is a way to split, I was taught that way when I was 15
[00:45:38] <Jymmm> I stil think I like the tire screw splitter.... any car, anywhere, no hassel
[00:45:47] <tjtr33> thats the flick, a twist right after contact, dont try to go thru
[00:47:03] <tjtr33> shes good even if its well dried
[00:47:21] <Jymmm> floor jack, 4-way tire iron, the screw splitter and you're good to go.
[00:47:49] <Jymmm> bonus is 1/4" plywood shield to save the paint job
[00:48:51] <Jymmm> I wonder how much HP would be needed w/o a car?
[00:49:53] <Jymmm> JT-Shop: I think you already saw the wood gas heater
[00:50:34] <nevyn> I used to have to split redgum for kindling.
[00:50:47] <nevyn> I was very careful which block from the stack I selected
[00:50:57] <Jymmm> redgum?
[00:50:57] <nevyn> no knots or branches nice straight grain.

[01:47:28] <Jymmm> starting 2nd now
[01:47:29] <nevyn> it drops all the kindling bits out
[01:47:36] <Jymmm> nice
[01:48:47] <Jymmm> ah, like the green one I showed earlier. I like it too

[01:52:37] <Jymmm> Though large redwood bark chips work best for weed control.
[01:52:41] <nevyn> the bit I don't get is what the cost/benefit is..
[01:52:58] <Jymmm> how so?
[01:53:09] <nevyn> so we would burn ~ 8m3 of firewood a year in a 40square house
[01:53:28] <nevyn> that's about 4hrs work for any of those big machines
[01:53:52] <nevyn> it was only a weekend work for 3 men and a simple axial splitter.
[01:54:09] <Jymmm> Ah, well think of this... you have the forest, bring that gut in for say $300 and have him do all that for you in a few hours.
[01:54:34] <nevyn> so it becomes a hire in the machine + guy problem.
[01:54:44] <nevyn> which might be worthwhile
[01:55:05] <nevyn> I suspect we did hire someone in to cut the rounds...
[01:55:11] <Jymmm> yeah, especially in certain areas of the country
[01:56:23] <Jymmm> cut and split all at once, sounds like a good deal to me
[01:56:56] <nevyn> so everything I've seen these guys splitting seems.. light
[01:57:06] <nevyn> and crappy.
[01:58:36] <Jymmm> Yeah, I really wouldn't know. I have touch/thought of splitting firewood in eons
[01:58:42] <Jymmm> except for camping

[05:03:42] -!- jfire has quit [Quit: Leaving.]
[05:04:46] <abetusk> sorry for my ignorance, but what does the code do? Is there any documentation, other than the source?
[05:05:11] <tjtr33> danielfalck, i used FreeCad again today, very nice
[05:06:23] <tjtr33> abetusk, it describes the path for a tool to move along ( and velocities and machne tool function like flush and in general, the things you'd do by hand, but very explicitly)
[05:07:37] <abetusk> I'm still unclear as to what this program's (or library's?) function is
[05:07:53] <tjtr33> abetusk, for a simple overview , there's the gcode reference in linuxcnc, its on the main desktop menu 'Linuxcnc G-Code Quick Reference'
[05:08:40] <abetusk> it sends out stepper driver signals over the parallel port? How does it "interpret" g-code? What does it interpret it to?
[05:09:50] <tjtr33> no, gcode is not that low level, its like driving instructions, start in CHicago, turn left 3 miles, stop, take lunch, go north 3days... like that
[05:10:04] <abetusk> I understand that.
[05:10:08] <tjtr33> the stepper signal are way below that level,
[05:10:15] <abetusk> So what is this program doing?
[05:10:55] <tjtr33> this program? what do you mean? linuxcnc?
[05:11:47] <abetusk> rs247ngc. I just compiled it using the Makefile provided and it created canon.o. What is canon.o? Is this a library of some sort?
[05:11:55] <abetusk> the link you provided
[05:12:50] <tjtr33> rs274ngc is not a program, it is a language. linuxcnc reads that language and coordinates machine functions and motion to accomplish the task described by the language
[05:13:22] <tjtr33> you say what you want in rs274ngc, linuxcnc executes your commands
[05:14:00] <abetusk> I feel like we're running around in circles. Anyway, the spec. there was the one Tom_itx already provided, but thanks anyway.
[05:16:25] <tjtr33> look at the diagram in section 4 of

[16:34:22] <tjtr33> ktchk, a Hungarian man 'hg5bsd' created galvokins.c .
[16:34:29] <tjtr33> This kinematics corrected for some geometric error ( elliptical focus maybe ).
[16:34:32] <tjtr33> You may be able to contact him thru his youtube list.
[16:35:15] <TwisteR> archivist, even with all that power managenent stuff turned off in kernel?
[16:35:59] <TwisteR> my laptop is pretty old and has LPT
[16:36:36] <Jymmm> Even with all that APM turned off in the BIOS too.
[16:36:43] <cradek> TwisteR: before wasting lots of time, boot the linuxcnc live cd and run the latency tests
[16:37:19] <TwisteR> ok, thanks, I will try that
[16:37:19] <archivist> I am not sure I have seen a successful laptop yet in the n years I have lurked in here
[16:37:52] <cradek> I have one laptop that works fine, PIII processor, used it ca 2007 at the various emc fests
[16:38:03] <cradek> well I think I still have it somewhere...

[16:48:12] <jensor> Axis 2 max velocity seems limited to programmed max velocity on axis 0. What would cause this?
[16:49:17] <pcw_home> the TP will be limited by the slowest axis in a multi-axis move
[16:49:44] <ktchk> I am using a fujitsu lifebook c1321 laptop for linuxcnc. under ubuntu 10.04 emc2.51
[16:50:04] <pcw_home> (so it keeps to the programmed path)
[16:50:31] <jensor> If I do g0 z 4 it will not go at the max rate. This is a single axis move
[16:50:51] -!- chopper79 has quit [Quit: Leaving.]
[16:51:51] <pcw_home> z is axis 2?

[16:52:43] <jensor> Don't know what you are asking

[18:04:50] <Loetmichel> never change a running machine
[18:04:51] <IchGuckLive> so save all you ngc needed and kill your PC with the latest Linuxcnc CD
[18:05:17] <IchGuckLive> Loetmichel: the interpreter is not getting this
[18:05:39] <Loetmichel> .. ok, dapper drake is six years old... COULD be goog to update, but first i would chek if the original setup works and the machine has genugh CPU and ram
[18:06:09] <jensor> Was thatba weakness that has since been cured?
[18:06:13] <Loetmichel> <- sots hins fingers
[18:06:21] <IchGuckLive> the 2.5+ will not run under dapper
[18:06:27] <Loetmichel> that is right
[18:06:56] <IchGuckLive> if he wants individuell speed he needs 2.5+
[18:07:15] <jensor> Will my ini and hal files etc still be compatible?
[18:07:22] <IchGuckLive> no

[18:54:53] <r00t4rd3d> I wonder how a Doodler would do on a cnc router
[18:55:30] <archivist> mrsun_, something you have to watch, not too hard but clean metal and the right flux
[18:55:53] <r00t4rd3d> mrsun_, Ive have silver solder before
[18:56:57] <mrsun_> well silver solder, very expensive .. brass "rod" for brazing quite cheap ... is there difference in how it flows etc? i guess the melting temp is alot lower on silver solder ?
[18:57:15] <mrsun_> and these flux covered rods, are they anything to have ?
[18:57:20] <archivist> spot the silver solder
http://www.collection.archivist.info/archive/DJCPD/PD/2005/2005_09_19_M_Cooper_Clock/P9091739.JPG
[18:57:22] <r00t4rd3d> you need to get it hot but not as hot as brass
[18:58:11] <mrsun_> what kind of death machine is that?!
[18:58:37] <archivist> a clock, with modifications
[18:58:40] <mrsun_> i know ive brazed in the forge before and there it seems that brass flows realy well also into cracks etc but i guess the less temp the better :P
[18:59:02] <Jymmm> mrsun_: Chrono Death Ray Machine
[18:59:11] <r00t4rd3d> what do you need to solder"
[18:59:13] <r00t4rd3d> ?
[18:59:17] <archivist> you need enough for it to flow nicely

[19:01:22] <Jymmm> archivist: and too many shiny things, where's the silver solder in that pic?
[19:01:25] <r00t4rd3d> ive use a normal soldering iron with it
[19:02:06] <Jymmm> it's a brass stove, so gets exposed to 1100F occasionally
[19:02:43] <archivist> the added brackets are built up on the clock
[19:02:44] <r00t4rd3d> silver solder wont work on that
[19:04:36] <mrsun_> work on what ?
[19:05:20] <Jymmm> 1240F melting point, 1355F flow point, maybe it might.
[19:06:44] <roycroft> jymmm: there are several silver solder alloys available, each with a different melting point
[19:06:51] <roycroft> that is how jewelers build up pieces
[19:07:05] <Jymmm> roycroft: So I see =)
http://lists.contesting.com/pipermail/amps/2000-January/015467.html
[19:07:13] <roycroft> they start with the high-temp solder and work their way down to the low temp solder as they build their piece
[19:08:25] * roycroft took a jewerlymaking class a few years ago, with hopes of gaining new skills that can be applied to general metalworking/machining, and was not disappointed
[19:08:52] <Jymmm> I alwas wanted to learn silversmithing
[19:09:12] <pcw_home> 1100F seems pretty hot for brass
[19:09:37] <pcw_home> at the minimum its going to anneal it
[19:09:41] <roycroft> i've soldered lots of brass with silver solder
[19:09:51] <Jymmm> roycroft: cool
[19:09:59] <Jymmm> I'll have to give it a try
[19:10:08] <Jymmm> roycroft: what did you use for flux?
[19:10:10] <roycroft> i usually use "easy" solder, which is the lowest melting point alloy
[19:10:20] <roycroft> a borax paste
[19:10:32] <Jymmm> hmmm
[19:10:57] <roycroft> from a jeweler outfitter
[19:11:19] <roycroft> i usually order from otto frei, but i sometimes get supplies from rio grande
[19:11:21] <Jymmm> oh, not just borax soap + water and make into a paste?

[19:11:29] <roycroft> that would probably work fine
[19:11:37] <roycroft> experiment with some scrap brass
[19:11:50] <Jymmm> no scrap brass available =)
[19:12:15] <pcw_home> try some cartridges...
[19:12:17] <roycroft> i'm sure you can get a small piece of brass tubing from a hardware store
[19:12:44] <Jymmm> roycroft: I could, just dont want to waste it =)
[19:13:30] <roycroft> better to waste a piece of scrap than damage your production piece
[19:14:20] <archivist> cand always solder a bit more onto the broken production
[19:14:39] <Jymmm> I doubt I could do that, it just the tinest of vapor leaks I'd like to seal up.
[19:15:02] <Jymmm> It's a a trangia burner
[19:18:43] <Jymmm> There seems to be a vapor leak where it's been crimped sealed

[19:29:57] <JT-Shop> I just got back from a customer, let me check
[19:31:04] <Loetmichel> mrsun_: brass and Phosphoric copper solder are fpr high temp stuff which has to carry huge loads, silver solder is for lower temp solder joints which has to be a bit more sturdy than SnPb solder

[20:59:28] <mrsun_> but has a tensil strenght of 250Nm compared to the silver solders 450 - 500Nm

[21:19:06] <mrsun_> so to make it easy on you, i need to solder steel to steel, where one part is galvanized but the galvanized part will be turned down in the lathe, dont know if the zink penetrates the metal but i guess not? is there a problem to solder things that are galvanized? :) so what type of solder should i use for this application =)
[21:19:36] <Loetmichel> mrsun_: with the right flux: yes
[21:19:58] <Loetmichel> wothout Flux: no chance
[21:20:17] <cradek> usually attachments of steel to steel are done by welding...?
[21:20:29] <mrsun_> but says on a page i find that phosphorous alloys are not good with steel cause it makes brittle joints
[21:20:32] <Loetmichel> depends: silver solder is possible on zinc
[21:20:47] <Loetmichel> SnPb solder also
[21:21:22] <Loetmichel> but the phosporic copper solder isnt, the zinc will burn off before the solder gets liquid
[21:21:41] <Loetmichel> mrsun_: it does
[21:22:00] <Loetmichel> it makes the STEEL britte to a certain degree as far as i remember
[21:22:11] <mrsun_> Loetmichel, i do not care about if the zink is still intact in this application tho =)
[21:22:32] <Loetmichel> is that a high load soldering?
[21:22:44] <Loetmichel> what is the pourpose?
[21:22:50] <mrsun_> Loetmichel, not realy as things will be threaded before soldering also :P
[21:23:02] <mrsun_> Loetmichel, tilting machine feet .. not a very heavy machine either :P
[21:23:16] <Loetmichel> so its just to prevent the nut from turning on the thread?
[21:23:30] <mrsun_> kinda, but i like it when stuff hold together :P
[21:23:38] <mrsun_> there will be a ball attached to the end of the threaded rod also
[21:23:56] <mrsun_> and thats the part i want soldered insted of welded
[21:24:06] <Loetmichel> use silver solder in sparse amounts and flux generously
[21:24:06] <mrsun_> ofc i could weld it then turn the weld down :P
[21:24:35] <Loetmichel> i would screw the ball on
[21:24:44] <mrsun_> Loetmichel, yes but they all say silver solder ... even the ag-cu-p solder ... then there are different ones but they cost like 10x what this rod does :P
[21:24:57] <mrsun_> Loetmichel, yeah thats what i was thinking, then solder it to make a solid joint :P
[21:25:00] <Loetmichel> drill a hole in the ball, thread it and screw it on top of the foot
[21:25:17] <mrsun_> i dont want the ball to unscrew when adjusting =)
[21:26:28] <mrsun_> and i find it a good opertunity to learn how silver solder etc works =9
[21:26:29] <mrsun_> =)
[21:26:42] <Loetmichel> mrsun_: "silver solder" is something like this:
http://shop.handwerkstadt-louis.de/artikel.php?artnr=4006062245102
[21:27:08] <Loetmichel> mrsun_: thats what green loctite is for ;-)
[21:27:18] <mrsun_> haha :P
[21:27:37] <mrsun_> loctite coasts like 5x what the highest grade brazing rod they have in town does
[21:28:15] <Loetmichel> mrsun_: but it is used a LOT less per joint, AND is undoable ;-)
[21:28:49] <mrsun_> and then you forget to put the cap on the bottle or soemthing
[21:28:52] <mrsun_> :P
[21:29:13] <Loetmichel> and you are not pressed to buy loctite, there is plenty of cheap "screw lock" on the market
[21:29:29] <Loetmichel> the cap wont hurt
[21:29:55] <Loetmichel> the screw locs harden with absence of air and presence of humidity and metal ions
[21:30:11] <Loetmichel> the stay liquid in the bottle more or less indefinetly
[21:30:51] <mrsun_> still good to learn to braze!
[21:30:55] <mrsun_> or solder or whatever =)
[21:31:03] <mrsun_> as it has alot more applications then just screw locking :P
[21:31:17] <Loetmichel> that is true
[21:32:22] <mrsun_> and in 99 out of 100 cases i always start in the wrong end, hardest first then go back to easier and easier ways :P
[21:38:17] <mrsun_> but a higher silver content solder without phosphor would be a better choice for steel to steel then ? :)

[22:32:36] <Connor> I know that the MESA card will source the 24v. can it handle a back current ? I.E. if the switch were to also source 24v to the relay..

[22:34:20] <skunkworks> Connor: that would be a question for peter
[22:35:03] <skunkworks> I have only used the mesa with opto22 interface modules
[22:36:10] <Connor> The output driver chips used on the 7I77 have built in Zener diode clamps to clamp
[22:36:10] <Connor> inductive turn-off (fly-back) spikes. This means that flyback diodes are not normally
[22:36:10] <Connor> required on inductive loads. If high current inductive loads are switched at high
[22:36:10] <Connor> frequencies, they should have flyback diodes to limit power dissipation the in 7I77's driver
[22:36:10] <Connor> chips
[22:36:42] <Connor> Not sure that'll protect the output side from 24v input...
[22:38:03] <skunkworks> sounds to me like 24v relay should be fine
[22:38:30] <skunkworks> (I concider a relay as a small inductive load) ;)
[22:38:41] <Connor> that's not the issue. I'm just thinking if I put a switch on to by-pass the MESA card to supply 24v to the coil, it's going to send 24v to the output side of the MESA card..
[22:39:09] <Connor> so, a diode may be needed.
[22:39:27] <Connor> unless that Zener diode will protect it from more than just spikes..
[22:40:25] <skunkworks> I don't think I understand what you mean
