[00:01:27] <Tom_itx> what net does hal look for on an axis home switch?
[00:01:32] <PCW> 0 --> 2^32-1 = 0 to ~360 electrical degrees
[00:02:29] <Tom_itx> halui.joint.0.home ?
[00:02:33] <andypugh> Nothing sensible in rawcounts?
[00:03:08] <PCW> Let me look again
[00:03:36] -!- theorb [theorb!~theorb@] has joined #emc
[00:03:49] -!- theorbtwo has quit [Read error: Operation timed out]
[00:03:59] theorb is now known as theorbtwo
[00:07:48] <PCW> OK looking more closely, rawcounts looks like its accumulating rapidly and wrapping
[00:07:50] <PCW> velocity looks right for positive velocities but something like 575999 - velocity for negative velocities
[00:13:39] -!- Loetmichel has quit [Ping timeout: 256 seconds]
[00:14:05] <andypugh> I think my binary arithmetic had let me down. It would work for signed longs, but bit for unsigned.
[00:15:53] <PCW> yeah looks like something of that sort
[00:15:55] <PCW> Its kinda cool to plug the resolver in and out and see the error flag change
[00:16:41] <Tom_itx> should i hook the home switch to axis.0.home-sw or halui.joint.0.home ?
[00:17:06] <andypugh> Tom_itx: neither
[00:17:13] <Tom_itx> where then?
[00:17:18] -!- Loetmichel [Loetmichel!Cylly@p54B152D5.dip.t-dialin.net] has joined #emc
[00:17:19] <andypugh> axis.0.home-sw-in
[00:17:52] <andypugh> halui.joint.0.home is actually a "home this axis now" request pin.
[00:17:56] <Tom_itx> ok i forgot the -in part :)
[00:18:00] <PCW> might be a nice feature to zero all the outputs if the error flag is set
[00:18:01] <PCW> (since I'm too stingy with hardware to do it in the RESMOM firmware)
[00:18:10] <Tom_itx> so do it at the axis level instead of halui
[00:18:12] <PCW> RESMOD
[00:18:23] <andypugh> OK, if you think it is the right thing to do.
[00:18:37] <Tom_itx> ok, carry on...
[00:18:50] <andypugh> Tom_itx: halui is best thought of as a user interface (it's also optional)
[00:19:05] <Tom_itx> i thought axis was
[00:21:02] <Tom_itx> andypugh, what about axis.0.pos-lim-sw-in ?
[00:21:12] <Tom_itx> as well as neg
[00:21:26] <PCW> TTGH Thanks Andy, pretty good so far considering you have no hardware!
[00:21:27] <andypugh> Do you have separate limit and home switches?
[00:21:34] <Tom_itx> is that if you use limits on both sides?
[00:21:41] <Tom_itx> no just a single switch
[00:22:01] <andypugh> net them all together then
[00:22:04] <Tom_itx> i know emc is multi purpose is why i'm asking which to use
[00:23:08] <andypugh> net signame pin-name => axis.N.home-sw-in axis.N.pos-lim-sw-in axis.N.neg-lim-sw-in
[00:23:14] <Tom_itx> ok, then which to net... pos-lim-sw-in or pos-hard-limit ?
[00:24:39] <andypugh> the hard-limit pins are outputs, telling you that you have hit a limit
[00:24:55] <Tom_itx> so i see
[00:24:58] <Tom_itx> ok
[00:25:31] <Tom_itx> it seems against nature to map the pos and neg but if you say so
[00:25:34] <andypugh> So, just net them all together on one line like I typed above.
[00:25:40] <Tom_itx> yeah
[00:27:09] <andypugh> It does, now you mention it. I think perhaps EMC2 is smart enough to give a generic limit error if it sees both trip.
[00:27:46] <Tom_itx> well i was gonna use a pos limit and a soft neg limit
[00:28:23] <Tom_itx> and a pos offset
[00:29:40] -!- Calyp has quit [Quit: Leaving]
[00:30:28] <andypugh> It does no harm to have a switch in case things go wrong. You can't really trust soft limits on an unhomed machine

[05:11:53] <tlbGantry> Can someone point me in the right right direction for defining custom keybindings for Axis?
[05:14:13] <tlbGantry> Or if it's even possible? Want to map keys to jog fourth axis.
[05:15:11] <SWPadnos> I think those are the , . keys by default
[05:16:21] <SWPadnos> you can re-map keys, but I can't tell you the specifics of how. there is an axisrc file, which may be the best way
[05:17:40] <tlbGantry> Swpadnos... Awesome, that's a step in the write direction. ;) Been googling for an hour and have come up with nothing..will look into the axisrc file. Appreciate it.
[05:18:03] <SWPadnos> sure. if you search the email or IRC archives, I'm sure you should find something
[05:19:47] <SWPadnos> ah: http://linuxcnc.org/docs/html/gui_axis.html#r1_11_4

[05:51:42] <tlbGantry> ok, understand basic binding now via rc file... Anyone have any thoughts on binding 2 operations to a single key press? The following doesn't throw and error...but doesn't work either... root_window.bind("<Up>", lambda e: jog_on(6, get_jog_speed(6)), jog_on(1, get_jog_speed(1)))
[06:09:05] <tlbGantry> Ok... got it. Hint for anyone else out there... Turns out it's all python.. just learn how to do a function... then bind to the function...in the function define as many opps as you want... Works great.

[09:48:43] <awallin_> what do you want to do with it?
[09:50:04] <stillme> making edge lit signs and lithophanes
[09:51:04] <TekniQue> http://www.worldofcnc.com comes to mind
[09:51:10] <TekniQue> but there are lots others
[09:56:08] <stillme> i am sorry if anyone from china is here, but i have to say this, i shouldnt have bought a cnc from china, but its a lesson well learned. i want to have other sources for when am ready to buy another

[14:01:37] <Valen> it has brushes?
[14:01:47] <Valen> most spindles i have seen are ac induction motors
[14:02:13] <TekniQue> DC motors are common in retrofits
[14:02:16] <TekniQue> or home made stuff
[14:02:39] <TekniQue> most hand tools have DC motors
[14:02:59] <Valen> if they are mains they will be "universal motors"
[14:03:08] <TekniQue> yes
[14:03:24] <Valen> but not the kind of thing you want doing 20K rpm for 10 hours a day
[14:03:34] <TekniQue> indeed
[14:03:40] <TekniQue> good for hobby stuff
[14:03:44] <TekniQue> because they're cheap
[14:04:37] <pcw_home> routers are normally universal motors I think
[14:04:59] <Valen> yeah i think your right pcw_home
[14:05:06] <Valen> http://www.cnczone.com/forums/general_metal_working_machines/118358-phenolic_basalt_head_our_hm45.html is ours
[14:05:37] <Valen> i think a number of routers are going to spindle motor style drives now for quietness and not sucking ass
[14:09:04] <pcw_home> I think for a hand tool its hard to beat a universal motor for speed and weight
[14:10:37] -!- TekniQue has quit [Ping timeout: 240 seconds]
[14:11:30] <Valen> i dunno, I would prefer either ac induction spindle motor or brushless DC
[14:12:33] <pcw_home> I doubt you would prefer an induction motor hand tool if you had to actually use it
[14:12:38] <Valen> you can get 800W spindle in a 65mmx210mm package
[14:13:19] <Valen> assuming its something like a router I think i'd prefer it over a screaming universal motor thats going to kill itself in a few weeks of use ;->
[14:13:53] <pcw_home> not if you have to actually use it (heavy and awkward)

[14:14:23] <Valen> theres no reason for it to be awkward
[14:14:45] <Valen> weight to my reccolection isn't that different
[14:15:31] <pcw_home> yes there is, a high speed induction motor will be long and thin and heavy for its power
[14:15:33] <Valen> 2.5kg somebody says
[14:15:53] <Valen> for one of these http://www.ebay.com.au/itm/WATER-COOL-MOTOR-SPINDLE-0-8KW-AND-MATCHING-INVERTER-g2-/170593446136?pt=UK_BOI_Industrial_Automation_Control_ET&hash=item27b82968f8#ht_11122wt_1141
[14:16:12] <Valen> thats in the ballpark for a pro series router
[14:16:34] <pcw_home> about 4 times the weight of an equivalent 1HP universal motor
[14:16:54] <pcw_home> which is why they are better for hand tools
[14:17:13] <Valen> i'd wager that the universal motor will pull 1HP from the wall but i doubt your going to be getting that out in the hand

[14:20:14] <Valen> and i'l bet you a coke which would be quieter
[14:20:19] <Valen> to me thats a big deal
[14:20:27] <pcw_home> thats the complete tool and packaging
[14:21:29] <Valen> its still in the ball park
[14:21:39] <pcw_home> yes but induction motors are not used on most hand tool for a reason: heavy and awkward
[14:22:03] <Valen> i think its because its cheaper and easier to make a universal motor
[14:22:16] <Valen> and until quite recently there was no other way to get 20K rpm
[14:22:31] <pcw_home> but its asl lighter an mor compact for a high speed motor
[14:22:42] <pcw_home> also
[14:23:08] <Valen> i'm dubious about your claim of lightness
[14:23:20] <Valen> given that both are basically lumps of copper and metals
[14:23:40] <Valen> and an induction motor is going to be higher effiecency
[14:24:03] <Valen> a first pass at it would predict the induction motor would be smaller and lighter for a given power output
[14:24:09] <Valen> note thats output

[14:33:27] <Valen> universal motor will work
[14:33:43] <Valen> it will just be (Rather) noisy and may have a shorter life than other options

[14:48:31] <JT-Shop> the air motor?

[14:55:58] <pcw_home> I know nothing about tool holders but I thought they just had a really strong spring an maybe an air cylinder release

[15:01:23] <JT-Shop> pcw_home: that type of mill has a drawbar and the impact wrench just tightens and loosens the drawbar
[15:02:12] <JT-Shop> my VMC is like you thought with a double air cylinder to release and springs and grippers to hold the pull stud
[15:06:42] <pcw_home> I short stroke air cylinder seems more appropriate (ear wise anyway)
[15:07:02] <pcw_home> s/I/A/
[15:09:49] <JT-Shop> that won't work on quills with drawbars
[15:21:22] <pcw_home> Not enough force?
[15:26:37] <JT-Shop> the draw bar is threaded and must be screwed in and un-screwed

[16:01:01] <JT-Shop> ah yes it clears everything except the cord reel
[16:01:25] <Tom_itx> you get that moving, it might decide not to stop
[16:02:01] <JT-Shop> it does have some mass to it and I don't go very much over a snails pace when moving it
[16:02:39] <JT-Shop> I calculated about 850lbs empty and guess 900lbs with rigging

[17:43:55] <Jymmm> damn, their lubed.
[17:43:59] <jdhNC> 7 cents each and worth every penny.
[17:44:14] <jdhNC> don't worry about the lead and stuff in there.
[17:45:18] <Connor> why are we talking about condoms ?
[17:45:35] <jdhNC> I know... linux + cnc + irc kind of obviates the need for them.
[17:45:51] <Jymmm> Well, China imposes fines if you get pregnant, so I suspect they might be quality
[17:46:22] <jdhNC> because 7 cent chinese crap condoms are just generically funny
[17:47:04] <Jymmm> If you buy US made online in bulk their that cheap too.

[18:02:34] <Danimal_garage> hows the trike coming?
[18:02:44] <JT-Shop> slow
[18:03:13] <JT-Shop> I hope to have the axle apart by first snow
[18:05:01] <Danimal_garage> well i didn't expect a 250 to be fast :)
[18:05:32] <JT-Shop> I just hope it is not to slow to be fun
[18:05:49] <Danimal_garage> throw a 500 in it
[18:06:06] <Danimal_garage> they have a 500cc version, right?
[18:06:09] <JT-Shop> just got finished adjusting the X axis belt on the VMC... how do all those chips get in there
[18:06:16] <JT-Shop> dunno about the 500
[18:06:40] <Danimal_garage> might be an easy swap if it comes to needing it
[18:07:07] <Danimal_garage> ha, yea, it's crazy how chips get in the weirdest places, huh
[18:08:08] <Danimal_garage> i got rid of my mustang a couple weeks ago :(
[18:08:17] <JT-Shop> I need to take all the guards off and clean clean clean
[18:08:24] <Danimal_garage> i miss that piece of crap already
[18:08:34] <JT-Shop> which one?
[18:08:51] <Danimal_garage> 99 mustang gt convertible
[18:09:08] <Danimal_garage> it's been my daily driver for like 6 years
[18:09:23] <JT-Shop> looks like there is two 250 models and no 500's
[18:09:42] <Danimal_garage> ah bummer, what is it again? A suzuki?
[18:09:54] <JT-Shop> yea a GZ250
[18:10:05] <Danimal_garage> it was the worst car for a daily driver, but it was fun
[18:11:10] <JT-Shop> the Boulevard S40 looks like a good one, 652cc single carb 63mpg
[18:11:54] <JT-Shop> single cylinder!
[18:12:00] <Danimal_garage> nice!
[18:12:25] <JT-Shop> belt drive
[18:15:18] <Danimal_garage> i got some little crapbox saturn now, but it gets like 27mpg
[18:15:42] <Danimal_garage> it's the vue, a small suv
[18:16:10] <JT-Shop> that's a bit better than my van it gets 24mpg average around here
[18:16:28] <Danimal_garage> nice, a sprinter?
[18:16:40] <JT-Shop> the van?
[18:17:01] <Danimal_garage> yes
[18:17:15] <JT-Shop> a chevy uplander
[18:17:44] <Danimal_garage> ah a mini van of sorts

[18:23:56] <JT-Shop> the spindle drive belt should be here in a couple of days... I don't look forward to changing that one out :/
[18:24:20] <Danimal_garage> PITA?
[18:24:23] <JT-Shop> while it is apart a new encoder belt will find it's way on the spindle
[18:24:25] <JT-Shop> yea

[18:24:43] <Danimal_garage> only on the lathe

[20:37:59] <Tom_itx> somebody was here working on a dual motor gantry recently
[20:38:03] <seb_kuzminsky> he reported a problem with high-speed jogging on his gantry machine and i have some questions for him
[20:38:06] * JT-Shop needs to put dual steppers with encoders on the plasma gantry so I can join in the fun
[20:38:29] <seb_kuzminsky> JT-Shop, tom E. is using vel-mode steppers and encoders
[20:38:43] <seb_kuzminsky> seems crazy to me but i'm just a software guy so i'll keep my opinion to myself
[20:38:45] <Tom_itx> was it posted here about bolt on drivers to the back of a stepper using CAN?
[20:38:46] <seb_kuzminsky> oops
[20:38:53] <Tom_itx> i forget
[20:38:57] <Tom_itx> i think it was
[20:39:14] <JT-Shop> I didn't even know you could use velocity mode with steppers
[20:39:23] <Tom_itx> i'm not sure why you would
[20:39:29] <seb_kuzminsky> it's simpler than position mode in some ways

[20:53:09] <PCW> I think Tom E was using velocity mode step/dir with feedback because he started with step/dir servos
[20:54:20] <seb_kuzminsky> did you look at the configs he posted on the emc-users list last week?

[20:55:03] <seb_kuzminsky> he claimed to be jogging at 3300 ipm, but i can't square that with the config he posted... something's been lost in the communication
[20:56:04] <PCW> No, I've been pretty busy trying to get new stuff out
[20:56:05] <PCW> wasnt his problem some kind of glitch in world mode?
[20:57:03] <seb_kuzminsky> he reported two or three problems in that email
[20:57:27] <seb_kuzminsky> one was "arrow keys jog in the MDI tab", which Jeff fixed but hasn't been released
[20:58:13] <seb_kuzminsky> the bug i'm chasing now is "high speed jogs don't work, but high-speed planned (coordinated) moves work"
[20:59:20] <PCW> is it possible the the jogs get closer to maxaccel?
[20:59:41] <seb_kuzminsky> hmm, could be
[21:00:25] <seb_kuzminsky> i think a free-mode jog just sets the commanded position to the soft limit and lets the joint do what it can
[21:00:50] <seb_kuzminsky> but i'll have to dig to see if that's true...
[21:01:06] <seb_kuzminsky> and i don't have a gantry config to work with, so first i need to make one...
[21:01:43] <PCW> Yeah so possibly that would touch the limits where some Gcode would not
[21:02:53] <seb_kuzminsky> yeah
[21:02:56] <PCW> There are still some remaining hardware stepgen bugs as well (but these show up more with bad latency)
[21:03:16] <seb_kuzminsky> stepgen bugs in hostmot2? i dont know anything about those..
[21:03:56] <A2Sheds> I'm working on the configs for a 2-axis gantry now using servos with rotary encoders, and Mesa 7i33 with Parker Gemini amps/controllers

[21:05:14] -!- mhaberler has quit [Quit: mhaberler]
[21:05:16] <PCW> Yeah if you have a lot of servo thread jitter the stepgen driver sees this as velocity errors (and wrongly fixes them)
[21:05:17] <PCW> when in fact for short term the stepgen hardware is a better reference than the thread
[21:05:53] <seb_kuzminsky> PCW, that makes sense...
[21:05:53] -!- isssy has quit [Quit: Visitor from www.linuxcnc.org]
[21:08:13] <PCW> The problem gets better when you set the stepgens maxaccel

[21:35:48] <Danimal_garage> i have g64p.003, and the p value seems to not jive anymore
[21:36:28] <Danimal_garage> it has always worked fine with 2.5pre and older. i checked other similar programs that use the p value, and it does it with them as well
[21:37:22] <cradek> G64 and G2 now both use the P word, so your code is ambiguous, and it should probably be disallowed with a more appropriate error
[21:37:43] <Danimal_garage> ah great
[21:37:53] <cradek> and it's very nice of seb to volunteer to fix it!
[21:38:01] * JT-Shop gets a cold cerveza and a corvus sandwich
[21:38:02] <Danimal_garage> ha
[21:38:23] <seb_kuzminsky> hehhe hay wait!
[21:38:30] <Danimal_garage> cradek: so i need to change all my programs?
[21:38:38] <JT-Shop> Dan for some strange reason I never mix setup and motion on the same line
[21:38:47] <JT-Shop> or go back to 2.5
[21:38:56] <JT-Shop> or 4
[21:38:57] <cradek> 2.5 will have the same problem
[21:39:01] <seb_kuzminsky> i sure hope dan didn't write that program! looks like machine-generated code
[21:39:02] <Danimal_garage> JT-Shop: mastercam does
[21:39:16] <JT-Shop> fire the post
[21:39:19] <Danimal_garage> cradek: no it doesnty, i switched rom 2.5pre
[21:39:25] <Danimal_garage> from*
[21:39:38] <cradek> but how old of a 2.5 pre?
[21:39:44] <Danimal_garage> seb_kuzminsky: could be mastercam :)
[21:39:59] <Danimal_garage> cradek: good point, not sure
[21:40:03] <Danimal_garage> 6 months?
[21:40:22] <JT-Shop> change your post processor
[21:40:27] <Danimal_garage> too late
[21:40:47] <Danimal_garage> i have hundreds of programs already
[21:40:55] <Danimal_garage> i'm guessing i need to change them....
[21:40:59] <Danimal_garage> :(
[21:41:20] <JT-Shop> not too late for new programs
[21:41:43] <JT-Shop> must be a way to write a script or something to parse them and fix them
[21:41:47] <Danimal_garage> i'm sure my customers will disagree when it holds up their parts lol
[21:42:17] <Danimal_garage> will 2.4.x work?
[21:42:42] <Danimal_garage> i could switch back to that, i'll just have to modify my hal for the velocity loop stuff
[21:43:22] <Danimal_garage> however i guess that would mean i could never update emc again
[21:44:04] <seb_kuzminsky> cradek, shouldn't the P apply to the most recent P-using G-code in the block?
[21:44:35] <JT-Shop> G2 P is pretty cool
[21:45:37] <JT-Shop> multi turn heilical arcs
[21:46:41] <Danimal_garage> guess i better get cracking on the program changes

[21:49:44] <andypugh> Cradek, do you feel like talking about G76 feed-in moves?
[21:50:44] <Danimal_garage> i just put the g64p.00x on the next line
[21:50:49] <Danimal_garage> works now
[21:51:04] <JT-Shop> cool
[21:52:21] <JT-Shop> I usually put G64 Pxx at the top of my files
[21:52:47] <Danimal_garage> weird, aluminum starts to corrode within minutes when bolted to a steel fixture when coolant is involved
[21:52:51] <Danimal_garage> both machines
[21:53:09] <Danimal_garage> not as bad when bolted to an aluminum fixture
[21:53:17] <JT-Shop> got that electrical circuit going
[21:53:22] <Danimal_garage> it oxidizes
[21:53:26] <Danimal_garage> yea
[21:53:48] <Danimal_garage> any remedies?
[21:53:50] <JT-Shop> galvanic reaction or what ever they call it
[21:54:01] <Danimal_garage> besides unloading the part faster
[21:54:13] <andypugh> Paper? PTFE paste?
[21:54:27] <JT-Shop> a non conductive surface between the two dissimilar metals
[21:54:34] <Danimal_garage> eh
[21:54:42] <Danimal_garage> too much work for mass production
[21:54:48] <cradek> seb_kuzminsky: none of the rest of gcode parses that way (except for N needing to be first, the order of words is never significant)
[21:54:57] <seb_kuzminsky> ah
[21:55:31] <seb_kuzminsky> so the proper fix is to disallow g64 and g2/g3 in the same block?
[21:56:16] <cradek> more generally, the proper fix is to disallow any two things in a block when they both use (or optionally use) P
[21:56:45] <seb_kuzminsky> right
[21:56:46] <seb_kuzminsky> ok
[21:56:49] <seb_kuzminsky> i'll look in to it
[21:57:00] <cradek> thanks :-)
[21:57:12] <cradek> I'm not feeling too great so it's probably beyond me right now
[21:57:31] <seb_kuzminsky> i'm busy with something else so it won't be this afternoon...
[21:57:36] <seb_kuzminsky> hope you feel better chris!

[22:17:29] <Danimal_garage> ha
[22:17:45] <syyl> ;)
[22:17:58] <Danimal_garage> some cat got mauled on my roof the other night
[22:18:09] <Danimal_garage> probably by a racoon
[22:18:10] <syyl> (just for record: i would never put a kitten in a meatgrinder)
[22:18:16] <syyl> (..unless i have to..)
[22:18:30] <seb_kuzminsky> yeah it'd be hard to clean all the fur out
[22:18:52] <syyl> get a dedicated meat grinder for cats
[22:19:07] <JT-Shop> the grinder I have if you can get into the hole it gets ground up and comes out the other end
[22:19:15] <Danimal_garage> it was banging around up there making all kinds of noise, then i heard a loud bang and it stopped. i went out there in the morning and apparently it fell on the hood of my van. there was blood and some chunks of beat
[22:19:31] <JT-Shop> beets?
[22:19:58] <Danimal_garage> meat lol

[22:38:04] <JT-Shop> well that one is overly complicated ...
[22:39:40] <zhanx> question on what software to use to process a STL to be to machine it on my cnc. Its a mask, so i want to do a top and bottom pass but I dont know how to edit the stl meshcam is making for me
[22:41:01] <andypugh> zhanx: You want STL to G-code?
[22:41:34] <zhanx> andypugh, i have to edit the STL before i can do the G-code but never done it before
[22:42:06] <andypugh> (Eek, I nearly melted my servo into the carpet)
[22:43:07] <andypugh> I am confused.
[22:43:25] <zhanx> let me upload the stl file and you will see what i mean
[22:43:30] <zhanx> its for halloween
[22:43:33] <andypugh> Is the STL going in to Meshcam, or out of Meshcam
[22:43:45] <zhanx> out
[22:44:23] <zhanx> hmm where can i toss a 9mb stl
[22:44:24] <andypugh> I would normally expect anything with "cam" at the end to create G-code (well, except for Jennicam, I suppose)
[22:45:29] <andypugh> I don't have any way to deal with STL anyway.
[22:45:39] <zhanx> k
[22:46:10] <andypugh> I understand the format, I have written code to parse it and create contours from it.
[22:46:45] <andypugh> (it is just a list of nodes and a list of faces made from those nodes)
[22:47:31] <andypugh> I would guess that your problem is telling the inside from the outside?
[22:47:57] <zhanx> yep
[22:49:08] <mikeggg> melted? uh-oh
[22:50:49] <andypugh> Well, this isn't an easy way, but a bit of code could look through the faces, consider only the X,Y coordinates of those faces and their order and put the clockwise ones in one file, and the anticlockwise in another
[22:51:41] <andypugh> As I _think_ STL uses that to define the face normal
[22:53:37] <andypugh> However, it is probably better to get a different sort of output from Meshcam.

[23:07:04] <andypugh> I didn't realise that the 8i20 was set to 7.5A, and I was using it like a stepper to try to work out the relationship between rotor angle and resolver null.

[23:10:09] <JT-Shop> oh wow
[23:13:56] <andypugh> On the plus side, I have figured out how to get the resolver to quadrature Arduino to work like an absolute encoder (simply by inhibiting counting until the 5i23 encoder counters have woken up.

[23:38:00] * JT-Shop still ponders a clever way to attach the 3/16 cable to the windlass spool for the ballista
[23:38:10] <Danimal_garage> ha
[23:38:23] <Danimal_garage> i dont care as long as the body is straight
[23:38:39] <Danimal_garage> cable crimps?
[23:39:09] <Danimal_garage> hole/set screw?
[23:39:44] <JT-Shop> hmm maybe a setscrew from the side would fit
[23:39:50] <JT-Shop> it's rather small spool
[23:39:56] <Danimal_garage> ah
[23:40:27] <andypugh> JT-Shop: Crimp on an aluminium nipple, like a throttle cable?
[23:41:38] <andypugh> I have had reasonable results by drilling a hole, inserting the wire, and hitting it Very Hard
[23:42:26] <andypugh> Neater might be a tangential groove out of the side of the drum, to a screw and clamp
[23:43:34] <JT-Shop> the sides have to be flush and it is very small so space it well like your yard every bit counts
[23:44:00] <JT-Shop> I think I can fit a hole and a set screw from the side
[23:44:40] <Danimal_garage> if it's a medieval weapon, i'd suggest wizardry
[23:46:17] <JT-Shop> LOL
[23:46:37] <JT-Shop> I think I have it now, thanks for the suggestions
[23:46:47] <Danimal_garage> are you going with wizardry?
[23:46:58] <JT-Shop> a combination of them
[23:47:34] <Danimal_garage> acceptable.
[23:48:03] <JT-Shop> now how much fun will it be to drill the hole...
[23:48:32] <Danimal_garage> depends on what you use for a drill
[23:48:51] <Danimal_garage> if drilling the hole is difficult, i bet tapping will be worse
[23:50:11] <JT-Shop> the tapped hole will be on a flat surface so no problem with that
