[15:20:34] <fragalot> just noticed my cnc mill has a bowed bed
[15:21:14] <fragalot> Z-0.32mm on the left, Z-0.07mm on the right, referenced to ~2/3 from the right
[15:21:25] <fragalot> (which I referenced as Z0)
[15:21:49] <archivist> chinese special?
[15:22:05] <fragalot> how'd you guess? /P
[15:22:19] -!- vladimirek [[email protected]] has joined #linuxcnc
[15:22:33] <fragalot> I never noticed because I normally always use the chinese special low-profile vice (which is actually quite good), that I had milled flat
[15:24:12] <archivist> I was reading a book machine tool reconditioning while in the "small library" this morning thinking I should write up some web pages from it :)
[15:24:23] <fragalot> go for it :)

[15:24:39] <archivist> its best part of 500 pages
[15:25:12] <archivist> you can fix what you have
[15:25:49] <fragalot> archivist: Do tell?
[15:26:30] <fragalot> http://www.cnc-sable.nl/images/portaal%20copy.jpg <= one of these things
[15:28:31] <archivist> hmm now I see it, what do you expect :)
[15:28:57] <fragalot> archivist: if I can get it flat to within .1mm that'd be... ok..ish
[15:29:37] <archivist> adjustment with shims and a scraper
[15:29:54] <fragalot> scraper?
[15:30:05] <fragalot> shims won't fix the bow it's got
[15:30:09] <archivist> but you have to get the operating planes right first
[15:30:42] <fragalot> atm the Y and Z appear to be very well aligned
[15:31:05] <archivist> work out where the bow is, it may be bent bars or the sheet which forms the table
[15:31:28] <fragalot> good point
[15:31:40] <archivist> you can get ground flat aluminium sheet
[15:31:42] * fragalot runs off to find a flashlight & his reference ruler
[15:31:53] <andypugh> fragalot: probe the bed, fix it in software
[15:32:08] <fragalot> andypugh: can EMC2 do that?
[15:32:11] <archivist> bodge!
[15:32:14] <andypugh> Yes
[15:32:17] <r00t4rd3d> Jymmm, I would want their gcodes.
[15:32:26] <fragalot> andypugh: if you tell me how i will marry you.
[15:32:43] <archivist> fragalot, but for some jobs that is not the right way
[15:32:54] <fragalot> archivist: this machine isn' right for those jobs
[15:32:57] <fragalot> :P
[15:33:01] <andypugh> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?ProbeKins
[15:33:04] <fragalot> all I use this thing for is minor PCB engraving
[15:33:27] <archivist> only ok for thin shit that conforms to the current bend (like pcb)
[15:34:03] <fragalot> that's the only material that this machine sees, so that's fine
[15:34:59] <fragalot> just checked with a caliper & a flashlight and it's most def. the bed
[15:35:24] <archivist> you can use the machine to mill itself flat too
[15:35:40] <fragalot> not really
[15:35:59] <fragalot> it's not rigid enough to mill alu perfectly flat
[15:36:20] <fragalot> if I push against the spindle I can easilly move it .5mm
[15:36:46] <fragalot> hence only using it for PCB engraving where hardly any forces are applied :p
[15:37:27] <fragalot> other than that it's a really good machine!
[15:37:29] * fragalot coughs
[15:38:06] -!- ktchk [[email protected]] has parted #linuxcnc
[15:40:46] <andypugh> fragalot: Welll, it's certainly a nice colour and well finished :-)
[15:41:44] <fragalot> andypugh: it is, it also feels really sturdy & heavy duty when you pick it up
[15:41:44] <fragalot> :D
[15:42:01] <fragalot> and the motors do all have quite a lot of torque
[15:42:06] <andypugh> Pity it isn't actually sturdy and heavy-duty then?
[15:42:18] <fragalot> well the Y rails are
[15:42:41] <fragalot> the Z is too due to it being so short
[15:42:55] <fragalot> the X .... well it's about as sturdy as my 3D printer
[15:42:56] <fragalot> :P
[15:43:10] <andypugh> Actually, that design should be fairly insensitive to bed warping.
[15:43:11] <fragalot> the mounts for it are strong though!
[15:43:30] <fragalot> andypugh: well if you start off with a bowed 12mm alu plate
[15:43:47] <andypugh> Have you tried mounting a dial indicator on the spindle mount and measuring the bow that way?
[15:44:30] <archivist> shouldnt take too much effort to scrape it flat
[15:44:37] <fragalot> andypugh: that's what i'm doing
[15:44:44] <fragalot> archivist: what do youmean by scraping it flat
[15:44:56] <andypugh> archivist: It seems to be anodised.
[15:45:00] <fragalot> it is
[15:45:21] <archivist> I know, it wont be to pretty but will be flat :)
[15:45:25] <andypugh> Ask Sable for a straight one?
[15:45:38] <andypugh> archivist: Have you tried scraping anodising?
[15:46:09] <archivist> I know I would prefer to mill that off first
[15:46:47] <archivist> I wonder how many microns they anodised
[15:46:49] <andypugh> New user by the name of "onejaboo yingthesky". Why am I suspcious?
[15:47:27] <archivist> very close to random that name
[15:47:53] <archivist> he will ask if denied
[15:48:02] <fragalot> andypugh: they wouldn't send me a separate bed, i'd have to send thewhole machine back
[15:48:08] <fragalot> and that costs more in shipping than the bed is worth
[15:48:58] <archivist> fragalot, there is a place not far from me that has some ground ally, I have a bit here
[15:49:30] <andypugh> A bit of ali tooling plate would be ideal.
[15:49:31] -!- vladimirek has quit [Ping timeout: 256 seconds]
[15:49:52] <andypugh> I believe that is made to a guaranteed flatness.
[15:50:31] <fragalot> derp
[15:50:40] <fragalot> I just loosened off the Y mounts
[15:50:45] <fragalot> the bow just doubled
[15:50:46] <fragalot> lol
[15:50:57] <fragalot> andypugh: and cost more than the whole machine?
[15:50:58] <fragalot> :P

[16:00:49] <archivist> noise was not bad at all
[16:01:17] <fragalot> it is compared to the 3D printer :P
[16:01:26] <fragalot> virtually silent that thing
[16:01:30] <archivist> but random rolled metal can be bent like that

[16:08:47] <fragalot> andypugh: Thanks for that ebay link btw, just emailed him
[16:09:01] <archivist> another thing you can do is pull your bent plate flat with webs under the plate
[16:16:20] <fragalot> no space to really do that without hitting the Y guides
[16:22:04] <andypugh> Fit a soft board on top, machine that flat.
[16:22:22] <andypugh> For extra credit make that a vacuum table.
[16:22:25] <fragalot> that's what I used to do
[16:22:50] <fragalot> my only problem then was that I either couldn't machine a large enough area flat for some workpieces
[16:23:08] <fragalot> andypugh: I had one, but the vacuum pump shat itself last year
[16:23:27] <fragalot> haven't bothered getting another yet
[16:23:54] <andypugh> Inicentally, I just watched this, a very clear demonstration of how a differential works:
http://youtu.be/K4JhruinbWc
[16:23:55] <fragalot> anyway, after that I used a block of PTFE that i machined flat & tapped
[16:25:13] <fragalot> andypugh: differentials are mad science
[16:31:07] <fragalot> andypugh: good video
[16:32:41] <fragalot> DAMN
[16:32:54] <fragalot> I managed to shift the bow but not get rid of it by taking out the nut assembly
[16:33:23] <fragalot> I was so happy when it stayed consistent past the mark I made last time
[16:42:58] <r00t4rd3d> buff it out
[16:48:17] <fragalot> i'll just go back to using my PTFE block until I can get a flat replacement plate
[16:52:19] <fragalot> I do like the repeatabillity of this thing if you don't apply forces
[16:52:34] <fragalot> bolted the old block on there, put the dial on there, absolutely perfect

[17:04:42] <Loetmichel> grrr... boCNC is neat, but has a little flaw... the pullout after each round when doing mutliple depths.
http://youtu.be/MaouaN3bqwc ... anyone knows a script/regex/tool to rid the Gcode from all pullouts except the last one?
[17:05:22] -!- tjb1 [[email protected]] has joined #linuxcnc
[17:05:47] <archivist> fragalot, is the current frame and slide flex and play such that no spindle will make it better
[17:08:14] <fragalot> True
[17:08:23] <fragalot> but the variable speed control would
[17:08:28] <fragalot> atm i'm stuck to 28k rpm
[17:08:43] <fragalot> which... isn't very optimal
[17:09:57] <archivist> rigidity and play are the things I fix first
[17:17:05] <andypugh> For variable speed, one of the little chinese spindles might be good.
[17:17:40] <andypugh> (I don't know anything about their quality, but they are at least designed for the job)
[17:18:59] <fragalot> andypugh: been looking at one of those too
[17:19:16] <fragalot> according to reviews they're fairly decent, and a lot quieter than that kress
[17:19:19] <archivist> ask Loetmichel about his
[17:19:36] <fragalot> Loetmichel: Are you the proud owner of a chinese spindle? if so, are you happy about it?
[17:19:41] <Tom_itx> 1.5kw spindles are limited to 10mm cutters
[17:19:47] <andypugh> quiet is much under-rated
[17:19:50] <Tom_itx> 2.2kw go up to 13mm
[17:19:55] <fragalot> Tom_itx: I don't use anything over 6
[17:20:19] <Tom_itx> http://www.mycncuk.com/forums/general-metal-wood-working/3624-chinese-1-5kw-spindles.html
[17:20:23] <Tom_itx> just reading that
[17:20:28] <archivist> I imagine 1.5kw will need a new machine
[17:21:19] <fragalot> archivist: not going to use it up to that power, I just want a speed control :P
[17:21:36] <Tom_itx> same here
[17:21:51] <Loetmichel> fragalot: see the cideo i posted above ;-)
[17:22:00] <archivist> what kind of motor now, perhaps just add a speed controller
[17:22:07] <Loetmichel> its the 800W kind, though
[17:23:03] <andypugh> 1.5kw seems cheaper than 800W..
[17:23:29] <Loetmichel> the 800W is a bit more compact, so it hs fitted better to my machine ;)
[17:23:42] <fragalot> and mine i'd imagine
[17:23:43] <fragalot> :P
[17:24:31] <Loetmichel> and the 800W kund hs an ER11 chuck, so a 6.5mm shaft is the biggest tha can be put in
[17:24:37] <Loetmichel> kind
[17:24:52] <fragalot> I do have a lot of 8mm shaft mills
[17:25:05] <Loetmichel> so you have to get an oversize chuck
[17:25:09] <Loetmichel> they are aviable
[17:25:18] <fragalot> that works
[17:25:20] <fragalot> how much did you pay for it?
[17:25:35] <Loetmichel> by standard 6.5mm is end, but some grind 8mm ones
[17:25:42] <Loetmichel> about 200 eur with VFD
[17:25:44] <Loetmichel> 300 Eur
[17:26:00] <archivist> Loetmichel, time you made a cnc punch

[17:28:53] <fragalot> wow ok
[17:28:59] <fragalot> I just heard my spindle stop
[17:29:01] <fragalot> and then go again
[17:29:10] <fragalot> so I check what's going on and it's not cutting anymore
[17:29:12] <fragalot> somehow
[17:29:19] <fragalot> I have no idea how, it's changed direction
[17:29:45] <fragalot> so spinning CCW now... on a 1phase 220V brushed chinese 220W spindle
[17:29:52] <fragalot> looks like i'll be getting a new one sooner than planned xD

[18:32:09] <fragalot> Right, i'm kinda getting closer to scrapping this whole machine
[18:32:34] <andypugh> But it's so pretty!
[18:32:58] <fragalot> andypugh: no good if i can't even get it within 0.2mm for Z height though
[18:33:03] <fragalot> even on a milled surface
[18:33:31] <archivist> add shims
[18:33:37] <andypugh> You mean the Z repeatability isn't there?
[18:34:20] <Loetmichel> fragalot: pic?
[18:34:34] <fragalot> what I did was made a lil' gcode program that milled only from left to right, go back outside the workpiece without moving Z, then take another 2mm pass
[18:34:53] <fragalot> then put my dial gauge on that
[18:35:01] <fragalot> and it's random 0.2mm up & downs
[18:35:05] <archivist> I wonder if the bars are truly at 90 to each axis and the pairs truly parallel
[18:35:08] <Loetmichel> ouch
[18:35:23] <fragalot> if I go over the piece again manually without touching the Z, it removes more material in some areas
[18:35:41] <fragalot> archivist: the bars, unloaded, are quite good
[18:35:47] <fragalot> they're just not very rigid
[18:35:49] <fragalot> at all

[18:38:13] <Loetmichel> ouch
[18:38:19] <archivist> fragalot, look what has bend/flex/play. fix, rinse repeat
[18:38:20] <fragalot> the only thing that looks good on this machine is the overall look, and the Y axis
[18:38:41] <fragalot> archivist: X rails & Z mount would be what needs to be replaced, and the bed
[18:38:46] <fragalot> eg. basically make a new machine
[18:39:44] <Loetmichel> fragalot: the machin doesent look so bad. that is a good base to fix. will not be for milling with a 80mmm flat head, but enogh for 3-6mm mill bits.
[18:40:10] <Loetmichel> when its not "play-free": MAKE it
[18:40:22] <Loetmichel> any of the slides can be fixed
[18:40:37] <fragalot> Loetmichel: yeah, like I said I would need to replace the bed, X rails, and spindle
[18:40:40] <fragalot> it's doable
[18:40:41] <Loetmichel> i would bet a whiole lot of money on something being loose/out of angle there
[18:41:14] <fragalot> i've checked every single nut & bolt on there, everything appears tight, the bearings all feel good too
[18:41:17] <archivist> fragalot, your last test, was the cutter new
[18:41:34] <fragalot> archivist: brand spanking new 2-flute 4mm endmill
[18:41:40] <andypugh> Suely someone out there on the Internet ha pedanticallt set up a Sable, then, documented the whole process to show off how coo they are?

[19:09:28] <fragalot> but still, the X flexes

[19:24:19] <JesusAlos> http://imagebin.org/244423
[19:25:04] <tjb1> I can only do 75mm tall 169x172
[19:25:17] <fragalot> torch time
[19:25:35] <r00t4rd3d> oh, I think they are like 6 inches high
[19:26:25] <tjb1> I dont have ABS either
[19:26:34] <tjb1> Someone said you can glue it with superglue but I dont know
[19:26:35] <fragalot> i've got some 3mm ABS & PLA kicking around
[19:26:48] <fragalot> tjb1: ABS glues nicely with an abs/acetone solution
[19:26:57] <andypugh> JesusAlos: in-not is an input pin, so you can't set it.
[19:26:57] <tjb1> I got pla with mine
[19:26:59] <fragalot> PLA.. doesn't really glue very great in my experience

[19:29:52] <archivist> fragalot, pressed or loctite
[19:29:53] <tjb1> But I think I had the extruder set up wrong so the layers werent actually bonding to each other

[19:30:16] <andypugh> JesusAlos: You need to give a value to set to, too.

[19:30:29] <andypugh> (for example)
[19:30:40] <fragalot> archivist: tried a blowtorch, that didn't appear to do the trick
[19:30:56] <fragalot> and I don't have a socket large enough to fit over the bearing to try and press it out
[19:30:59] <fragalot> :'(
[19:31:09] <archivist> fragalot, I am not a fan of that stuff, press/hammer and more heat
[19:31:20] <fragalot> archivist: yeah
[19:31:45] <archivist> fragalot, or add some spring to take out the play
[19:32:19] <fragalot> YES
[19:32:22] <fragalot> it's MOVING
[19:32:27] <archivist> forcing the inners towards each other
[19:32:53] <fragalot> bench vice, adjustable wrench + hanging off of the end of the vice bar with a pipe
[19:32:56] <fragalot> xD
[19:33:19] <fragalot> archivist: how would I do that
[19:33:56] <JesusAlos> andypugh: and for analog out can do the same?
[19:34:02] <archivist> a wavy spring
[19:34:17] <andypugh> JesusAlos: Yes
[19:34:28] <JesusAlos> with kind value number?
[19:34:45] <fragalot> archivist: too late now anyway :P and LM12UU's are cheap
[19:34:52] <fragalot> i've managed to press it out ~3mm sofar
[19:34:53] <andypugh> I am not sure if it a 0 to 1 range, or a -1 to 1, or -10 to 10
[19:34:57] <skunkworks> andypugh: do yo know off the top of your head how fast the 5i25 can output step pulses?
[19:35:01] <fragalot> only another 35 to go!
[19:35:10] <andypugh> skunkworks: I think 10MHz
[19:35:14] <archivist> fragalot,
http://www.assocspring.co.uk/p/23/wave_spring_washers/ but you want one with more waves in it and reasonable strong
[19:35:18] <skunkworks> andypugh: thanks!
[19:35:30] -!- norbert has quit [Quit: Verlassend]
[19:35:45] <fragalot> archivist: I don't see what you want me to do with that
[19:36:18] <fragalot> it's play in the linear bearings themselves
[19:36:23] <andypugh> archivist: These are very useful.
http://www.assocspring.co.uk/p/41/multiwave_compression_springs/ I have one to retract the piston on my toolchanger
[19:37:03] <archivist> andypugh, I got some multi wave when I was scrapping stuff :)
[19:38:11] <archivist> fragalot, need to add some compression across the opening for that then (if the housing is slotted)
[19:38:42] <fragalot> it's not a slotted housing
[19:38:57] <fragalot> very tight bore through a solid alu block
[19:39:14] <archivist> then get the right sized bar for the bearing
[19:39:20] <fragalot> have
[19:39:24] <fragalot> it's nearly all out
[19:40:04] <fragalot> courtesy of a very heavy hammer and bar stock that looks like i'll need to cut the end flat again before trying the next bearing
[19:40:07] <fragalot> >.<
[19:40:37] <archivist> belville washers are a nice toy to make springs to suit jobs
[19:40:59] <fragalot> first one, OUT!
[19:41:25] <fragalot> wow
[19:41:57] <fragalot> measured the bearing, very nice 21mm... measured the hole it came out of, 20.9
[19:42:12] <fragalot> 20.93*
[19:42:36] <fragalot> oh great
[19:43:48] <fragalot> now that it's out, i've found 2 hidden screws to adjust it the other way
[19:43:48] <r00t4rd3d> http://www.thingiverse.com/thing:25664
[19:45:07] <archivist> I wonder how many days the hinge will last
[19:45:12] <fragalot> (with hidden, I mean that they're in line with the mounting screws & so deep I never saw them)
[19:45:35] <fragalot> neat concept
[19:47:37] <JesusAlos> andypugh: what mean .in_not
[19:47:51] <JesusAlos> in pin name
[19:48:22] <tjb1> Get out r00t4rd3d, linking ipad items…tisk tisk
[19:48:38] <andypugh> if the input is true, then in = 1 and in_not = 0.
[19:49:01] <andypugh> in_not is just provided for convenience when you want a pin that works the opposite way.
[19:49:12] <JesusAlos> ok

[20:08:56] <fragalot> booyah. spindle now only flexes rather than rattle.. still 0.05mm though, but that's alright
[20:10:36] <Loetmichel> ouch
[20:10:54] <fragalot> Loetmichel: hey, it's 0.30mm better than it used to be
[20:10:55] <fragalot> xD
[20:10:58] <JesusAlos> http://imagebin.org/244429
[20:11:04] <Loetmichel> i meant the gonads ;-)
[20:11:04] <JesusAlos> I have doubt
[20:11:47] <fragalot> Loetmichel: lol yeah
[20:12:03] <JesusAlos> "VFIELD" pin is for outpts and "VIN" Pins for inputs?
[20:12:11] <fragalot> right, if I put a bit more force on it (eg; what it might see if I drill 2mm into plastic), it still moves 0.2mm
[20:12:35] <fragalot> JesusAlos: looks like it
[20:12:56] <fragalot> JesusAlos: VIN is for the logic, eg. the controller itself
[20:13:06] <fragalot> .. wait
[20:13:07] <archivist> fragalot, trick time, can you move one or both bars farther apart to remove that play
[20:13:27] <fragalot> archivist: wouldn't that create a slight bow in the movement
[20:13:28] <fragalot> ?
[20:13:56] <archivist> removing play only not adding strain
[20:14:28] <fragalot> it's not really play though, it's more leverage & 12mm rods
[20:14:59] <archivist> besides any strain should balance so bars will bow towards each other leaving the carriage in the middle
[20:15:26] <archivist> 12mm is a bit thin
[20:15:32] <fragalot> yup
[20:15:50] <fragalot> might aswell replace them with 16mm backed ones
[20:17:24] <fragalot> http://www.ebay.de/itm/CNC-Set-16x-300mm-Breite-Linearfuhrung-Linear-Guide-Rail-Frase-Wellenfuhrung-/221174078137?pt=LH_DefaultDomain_77&hash=item337f009ab9 these look alright

[22:46:55] <DaViruz_> i doubt it could react in time
[22:47:08] <DaViruz_> most times at least
[22:47:41] <fragalot> it could still minimize damage
[22:48:08] <DaViruz_> i guess
[22:48:39] <andypugh> If electrical contact breaks, and then re-makes, e-stop. It could work.
[22:48:46] <DaViruz_> i've crashed a big mill twice. not very pleasant
[22:49:23] <fragalot> I once witnessed a really odd crash on a massive mill
[22:49:27] <DaViruz_> through no fault of my own luckily, since it wasn't mine
[22:49:44] <Jymmm> http://www.youtube.com/watch?v=LGiYlyo2-eQ
[22:49:45] <fragalot> it had a 60something toolchanger, which somehow managed to get out of sync during a series production run
[22:49:57] <fragalot> and rather than grab a drill bit, it decided it needed a depth clock
[22:50:07] <fragalot> spun that up to 1200rpm, and smashed it into the workpiece
[22:50:36] <fragalot> Jymmm: I love that idea :)
[22:50:44] <fragalot> sure, it's expensive, but how much is your finger worth?
[22:51:23] <Jymmm> http://www.youtube.com/watch?v=E3mzhvMgrLE&NR=1&feature=endscreen
[22:51:44] <fragalot> was just going to mention that, lol
[22:51:46] <fragalot> also, gnite!
[22:52:01] <DaViruz_> if you wrech several a week due to damp wood i imagine it would be annoying
[22:52:06] <DaViruz_> wreck*
[22:53:45] <fragalot> DaViruz_: apparently it's not that sensitive
[22:54:11] <DaViruz_> it is amazing how little damage there is in the sausage
[22:54:36] <fragalot> Aye! :D
[22:55:17] <DaViruz_> oh he's trying it on his own finger
[22:55:43] <fragalot> he's touching it on the side tho
[22:56:13] <DaViruz_> and pretty slowly
[22:57:02] <fragalot> I'm just waiting for americans filing claims because they got an aluminium chip in their eye from that system
[22:57:05] <fragalot> :P
[23:00:35] <Jymmm> Nah, that's covered under "Wear ANSI approved safety gear"
[23:02:05] <Jymmm> It's suppose to be a good saw, but what about after it's been triggered? Does it warp/twist anything?

[23:06:49] <minibnz> hi guys does anyone know of any links to assit me in hooking up a set of DRO Scales (fed to an arduino) to provide axis feedback from my steppers
[23:06:56] <Jymmm> same diff =) phucking cold and sticky fish
[23:07:01] <Jymmm> stinky
[23:07:05] <andypugh> Aye.

[23:07:14] <minibnz> ih ave the arduino code sorted, need help hooking into EMC and HAL
[23:08:27] <minibnz> i am guessing i need to write a python script that produces the out put and feeds that to the hal but i cant see where to start.
[23:09:21] <minibnz> ih ave basic open loop setup working but want to close the loop.

[23:22:00] <minibnz> does anyone know where i can find a list of all the standard EMC variables that are available to a python module?
[23:22:17] <minibnz> is there such a document? or am i dreaming....

[23:23:04] <micges> minibnz: what variables?
[23:29:52] <jdh> anyone have a 40ish watt chinese laser?
[23:33:19] <minibnz> <micges> was hoping to find a variable that i can load up with the DRO Scale feedback..
[23:34:18] <minibnz> that is to say, if i move the bed X +10 and it only moves 9.9mm the DRO output is 9.9mm and this number is fed back to genereate an error value of 0.1 and then the iocontrol system would fix that..
[23:34:31] <minibnz> by generating more pulses for my steppers..
[23:35:11] <minibnz> my end goal to close the loop on my stepper fed axis. i have the DRO's hooked up to an arduino. just rying to work out how to get that feedback into EMC
[23:36:00] <minibnz> I have found some documents on HAL and how execute the python modules. but need to know how to pass the info in and out
[23:37:29] <minibnz> there is lots of info in the HAL user manual and i am working my way thru that, but it would be nice to have a cheat sheet like table that says this is the variables that you can use in python modules by default. that way i dont take the hard path and make my own module that dupicates whats already there
[23:38:13] <minibnz> then i could be reading the manual and have an idea that this is how i will do things....
[23:38:53] <minibnz> like what format the feedback numbers would be taking, are they 24bit floats or 32bit floats.. stuff like that..

[23:41:12] <minibnz> like i just found a section on how to take a reading and process it X number of times per second, this would be all i need if i new the variable name to load the read data into..
[23:41:39] <minibnz> i did see somthing that was close but its not what i thought it was.. it was only a output not an input for feedback.

[23:43:05] <pcw_home> how is the Arduino connected to the PC?
[23:43:57] <Tom_itx> probably serial via usb
[23:44:00] <minibnz> usb
[23:44:22] <minibnz> but if timing is an issue i can use the real serial port.. if needed.
[23:45:09] <minibnz> looks like the section i want isnt documented yet.. ncoder
[23:45:10] <minibnz> Software based encoder counter. See section [?
[23:45:35] <minibnz> and there is no section for the encoder in this document.. maybe its out there...
