[01:23:02] <somenewguy> hahawhat
[01:27:40] <RyanS> I knew I was not the only person thinking of this http://psas.pdx.edu/lv2cspincan/ToolPostGrinder1.jpg
[01:51:46] <somenewguy> why is the ngcgui subroutines forum so dead? there is no way all you folks don't have a handfull of nice subs that you use all the time
[01:55:17] <archivist> methinks docs are the right place, what do they say
[01:56:25] <FinboySlick> archivist: Up early or late?
[01:56:47] <FinboySlick> Oh damn... It's later here than I thought!
[01:59:14] <somenewguy> ?
[02:00:16] <archivist> 7:45 am :)
[02:00:30] <FinboySlick> somenewguy: I have 5h difference with archivist. Was surprised to see him active but it turns out that I'm the one staying up way past bedtime.
[02:01:01] <somenewguy> haha oh
[02:01:03] <archivist> sleeping is for the week
[02:01:11] <archivist> weak even
[02:01:20] <somenewguy> I was just confrused, I thought that was a resposne to me originally
[02:01:21] <FinboySlick> archivist: Heh, both work!
[02:01:31] <somenewguy> didn't realizee myconnection had dropped and I am just jumping into a conversation lol
[02:01:35] <somenewguy> man I could use sleep for the week
[02:01:36] <FinboySlick> Assuming you work weekdays.
[02:01:45] <somenewguy> up all night stopping the pipes from freezing
[02:02:03] <somenewguy> plus working nights AND days cause apparently I hate myself....
[02:02:21] <somenewguy> its 3am here
[02:02:23] <FinboySlick> somenewguy: Tell me about it. My mother had to cancel purchase of a house because the previous owner turned off the breaker when she left.
[02:02:46] <FinboySlick> To make matter worse, it's a hot water central heater.
[02:02:54] <somenewguy> rough
[02:04:19] <archivist> winter has been mild so far here
[02:05:04] <somenewguy> winter has been mill over here
[02:05:09] <somenewguy> get it?
[02:05:11] <somenewguy> cause I'm milling
[02:05:14] <somenewguy> and its winter
[02:05:18] <somenewguy> ....oh god I should sleep
[02:05:37] <somenewguy> I honestly thought that would be funny
[02:06:14] <FinboySlick> somenewguy: I'm just glad that I'm not the only one being silly for once.
[02:07:25] <somenewguy> heh. After discovering apparently my new ac/heater doesn't actually work if it is too cold, I could use to let lose a bit
[02:07:48] <somenewguy> happy thoughts
[02:08:06] <FinboySlick> What temperature is it where you are now?
[02:09:09] <FinboySlick> It's warming up here apparently, -22C.
[02:10:17] <somenewguy> nice
[02:10:28] <somenewguy> its been unseasonably cold lasst few days, and windy
[02:10:34] <archivist> I have some fridges that are useless in the cold
[02:11:05] <FinboySlick> archivist: Can't have *one* fridge, like any sensible person huh?
[02:12:11] <FinboySlick> (I think I'm catching up to somenewguy here)
[02:12:13] <somenewguy> but its been sitting at like 0f with a winchill around -10 -20
[02:12:27] <somenewguy> aren't all fridges useless in the cold...
[02:12:37] <archivist> main fridge fails at about 10 deg c room temp, so trying out some peltier things off ebay
[02:12:39] <somenewguy> like its just a cabinet that you plug in at that point
[02:13:10] <archivist> silly thing think they need to defrost and cook the contents
[02:13:28] <somenewguy> so in the cold your fridge becomes a stove?
[02:13:32] <somenewguy> nice feature
[02:13:49] <archivist> my house is unheated so they shout still work not cook contents
[02:13:59] <archivist> should
[02:14:04] <somenewguy> a few yearsago when I was living out of my car I used to keep things in the fridge in the winter to stop them from freezing
[02:14:07] <somenewguy> the fridge was off of course
[02:14:30] <somenewguy> fridges can be strange things I guess
[02:15:12] <FinboySlick> archivist: How about a stirling cycle fridge?
[02:15:53] <archivist> I would have to make or buy it
[02:16:11] <FinboySlick> With a good enough sink for the hot side, you can get pretty darn cold with those.
[02:17:20] <FinboySlick> Okay, off to bed for real this time.
[02:17:41] <archivist> I am waiting on fleabay to get a temperature controller to play with a wine cooler I have that has a dumb controller going into defrost
[02:22:10] <somenewguy> just build your own with a microcontroller
[02:22:21] <somenewguy> everyone needs an arduino or threee
[02:22:43] <archivist> I do not need an aaaaarguino ever!
[02:22:47] <somenewguy> I think Iam gonna wrap up for the night. This damn subrouting isn'tgetting fixed tonight
[02:22:54] <Deejay> moin
[02:22:55] <somenewguy> hahaha I see someone has opinions onthematter
[02:22:59] <somenewguy> night
[02:23:00] <archivist> mebe
[02:23:05] <somenewguy> well actually
[02:23:08] <somenewguy> maybe
[02:23:31] <archivist> I used to write assembler in the day job
[02:24:20] <somenewguy> and then you went crazy?
[02:24:35] <somenewguy> I'm a mechanical engineer, C++ is hard enough
[02:24:55] <somenewguy> (I say that but i am enjoying coding more and more every time I do it)
[02:25:56] <archivist> I started out with radio and tv repair moved to welding,then electronics then programming then mechanical
[02:26:18] <RyanS> never enjoyed but was not completely abysmal at programming
[02:26:29] <somenewguy> I would suspect most of us on here end out doing a whole bit of everything
[02:26:42] <archivist> engage brain make hands do what I want except correct speeelin
[02:26:42] <RyanS> Actually I really disliked
[02:27:09] <somenewguy> I wonder what the ratio of folks who use linuxcnc to makemone vs lose money is
[02:27:10] <archivist> I hate maths
[02:27:12] <somenewguy> spelling isoverated
[02:27:30] <somenewguy> i likemath
[02:27:33] <somenewguy> its right,or its wrong
[02:27:39] <somenewguy> no grey
[02:27:43] <somenewguy> or gray
[02:27:50] <RyanS> I think I always hear "this saving money business is expensive"
[02:28:00] <somenewguy> to prove my own point...
[02:28:00] <archivist> I started using it to make money but its not properly feeding me yet
[02:28:16] <RyanS> I will get a $3000 a milling machine to make a $50 part lol
[02:28:29] <somenewguy> ryans, yah that sums me up pretty much
[02:28:46] <somenewguy> I got a 3d printer that is paying for itself, and usedthat to justify getting the mill, which has a long way to go
[02:29:08] <somenewguy> its jsut a little desktop, but I needed like 40 hoels drilled in some square stock, coulda done it on a bridge port in a day...
[02:29:21] <RyanS> can you 3-D print in wax. I'm thinking lost wax metal casting
[02:29:37] <somenewguy> no, PLA and ABS plastic
[02:29:53] <somenewguy> although the pla melts at a low enough temp, I've heards of ppl burning itout of a mold
[02:30:08] <RyanS> Think that would work for casting? I think I saw some video
[02:30:19] <somenewguy> I do, I have been trying to make the time to try such a thing
[02:30:23] <archivist> the amateur market dont like buying gears in because they can make it cheaper, except they dont factor in their time or machine or tooling costs
[02:30:46] <somenewguy> havea small wood fired oven that I can melt aluminum in
[02:31:01] <somenewguy> haven't pulled it out since I got the printer tho
[02:31:28] <RyanS> hmm don't need much heat?
[02:31:29] <somenewguy> yeah archivist, i only recently figured out how to value my time properly
[02:31:55] <somenewguy> ryans, not really. you can print so its like 10% or less plastic by volume, so a torch would melt it out
[02:32:19] <somenewguy> PLA goes liquid at 180C or so
[02:33:04] <RyanS> Sorry I meant to melt aluminium. I thought you need a gas forge
[02:33:13] <somenewguy> oh
[02:33:40] <somenewguy> its a 5 gal steel bucket lined w/ cermainc wool, reinforced on the inside w/ a skim coat of refractory cement
[02:33:56] <somenewguy> shop vac blows in the bottom, melts aluminum pretty easy
[02:34:12] <somenewguy> maaayyyybeee I could melt steel in it, but it would be a push
[02:34:44] <somenewguy> ok im gonna wrap up, catch yall tommorwo
[02:35:40] <RyanS> cya
[02:35:59] <RyanS> achivist Speaking of gears Think this would be at all accurate? http://www.youtube.com/watch?v=5ygh6gmlC0Y&feature=player_detailpage#t=22
[02:36:55] <RyanS> Inkjet printers are reasonably accurate. I guess
[02:38:35] <archivist> RyanS, just get a dividing plate that paper disk is a bit naff
[02:40:07] <archivist> even better get a rotary table that includes the dividing plates
[02:42:42] <RyanS> I suppose you could mount the rotary table vertical on cross slide
[02:43:59] <archivist> but there is a good example of "amateur quality" where he could buy better for less
[02:50:57] <RyanS> The vertical travel could be problematic
[04:18:05] <CaptHindsight> you can 3d print wax with an extruder a low res but most use SLA (laser or DLP) to print molds for lost wax casting at high res
[04:20:33] <CaptHindsight> 3d systems uses the xerox (tektronics) printheads to print with wax
[04:25:29] <CaptHindsight> http://oliviervanherpt.nl/3d-printed-beeswax/ low res beeswax with a glue gun printer
[06:17:45] <MattyMatt> http://www.ebay.com/itm/Photoelectric-Speed-Sensor-Encoder-Coded-Disc-Freescale-Smart-car-/121147926866
[06:18:17] <MattyMatt> 100 slot encoder. make your own jogwheel
[06:23:01] <MattyMatt> I wonder how many rpm that could handle. I could estimate from watching one side on my single trace scope
[06:28:34] <MattyMatt> archivist, wouldn't fitting a stepper on a rotary be cheaper than a set of dividing plates? less error prone too IMO
[06:31:24] <MattyMatt> until you forget to work the locking clamps :p
[06:34:37] <MattyMatt> I guess it's the hydraulic brake that makes the difference between a £5000 cnc rotary and a £100 manual one
[06:36:19] <MattyMatt> my cnc one is belt drive with no brake :p
[06:39:11] <MattyMatt> I could fit a curved brake shoe around the edge, applied by a motor & cam
[06:40:39] <MattyMatt> or simply make my next rotary out of a drum brake wheel hub
[06:41:07] <MattyMatt> arr that be the way
[06:41:46] <MattyMatt> they are about 6in diameter on an old mini
[06:42:04] <CaptHindsight> is the goal maker quality ghetto style?
[06:42:26] <MattyMatt> goal is top quality, without cash investment
[06:42:59] <CaptHindsight> is time an issue? you can hover over fleabay and wait for a deal
[06:43:20] <MattyMatt> bargains are rare on ebay.uk atm
[06:44:00] <CaptHindsight> parcel post USPS
[06:44:12] <MattyMatt> trying to get an iron surface plate cheap is getting annoying
[06:44:56] <MattyMatt> I doubt any rotary will fit in the 5kg postage limit :)
[06:45:01] <CaptHindsight> what size? 3' x 4'?
[06:45:19] <MattyMatt> 2' x18" is about right
[06:45:32] <MattyMatt> I can survive with an 18x12 tho
[06:45:39] <CaptHindsight> how about granite in that size?
[06:45:52] <MattyMatt> nahh, I want iron, so I can use magnets
[06:46:22] <CaptHindsight> do you want t-slots as well?
[06:46:48] <MattyMatt> nope plain flat is fine
[06:46:48] <CaptHindsight> or just a flat hunk of iron?
[06:47:44] <MattyMatt> I need flat just for measuring and layout, but I'll probably use it for laying up granite-epoxy moulds too
[06:47:59] <CaptHindsight> how much does an hours worth of surface grinding go for there?
[06:48:50] <MattyMatt> I wouldn't know. probably not much if it's at a car head skimming place
[06:49:19] <CaptHindsight> scrap iron + 1 hour
[06:50:18] <MattyMatt> I'd have to get it upstairs, so a proper ribbed one rather than a solid block is desirable
[06:50:23] <CaptHindsight> auto head mill is typically a fly cutter so the surface ends up with a little bite
[06:53:06] <MattyMatt> I could make up an mdf one, mill it flat, put on the glass, then glue on shim steel
[06:53:32] <CaptHindsight> "I don't want to sound like a dick or nothing but" avoid #reprap for 1-2 weeks, you'll find what you're looking for and gain perspective
[06:53:37] <MattyMatt> or forget the steel and magnets
[06:54:44] <MattyMatt> ah I'm upstairs at momma's. I got my full fill of grief for the last iron tool I hauled up the stairs :)
[06:55:38] <MattyMatt> "It'll damage the floor" "It's no heavier than your husband"
[06:57:01] <MattyMatt> avoiding irc altogether does wonders for my perspective and productivity :p
[06:58:33] <archivist> MattyMatt, of course but he was showing a manual method
[07:01:07] <archivist> I got a dividing head for 3 quid plus the fuel to fetch off fleabay a few weeks ago
[07:01:13] <MattyMatt> nice
[07:01:56] <archivist> was sold as faulty and minus the dividing plates
[07:02:31] <archivist> am intending to upgrade with a servo or stepper drive
[07:02:31] <MattyMatt> the operation of those does seem a complicated to me, but I guess you get used to it pretty quick
[07:03:25] <archivist> I have dividing plates that have never been used, came with the b axis I got for the mill
[07:04:24] <MattyMatt> they be easy enough to make with a 3 axis mill I'm sure
[07:05:18] <MattyMatt> any hole position error would be tiny by the time it bacame a head angle
[07:06:22] <archivist> that is what most people like to think, often the final error is a lot worse due to the worm and wheel in the head
[07:06:47] <MattyMatt> arr
[07:07:20] <archivist> when I get around to it I will make a page documenting one of the rotaries errors one day
[07:07:33] <MattyMatt> I'm gonna upgrade mine to M8 worm on a wheel cut with a tap
[07:07:51] * archivist shudders
[07:07:52] <MattyMatt> the belt drive was only intended to last long enough to do that
[07:07:53] <CaptHindsight> is anyone making a machine quality wood composite?
[07:08:28] <MattyMatt> betonboard seems to be the best plywood for that
[07:09:01] <MattyMatt> it's that hard epoxy soaked stuff. in europe they use it for concrete shuttering (hence the name)
[07:09:04] <archivist> CaptHindsight, probably that stuff Loetmichel uses with is a resin impregnated ply for vehicle trailer floors
[07:09:47] <CaptHindsight> plywood is too unstable, was thinking more about wood particles <100um + polyester or epoxy
[07:10:00] <MattyMatt> I've seen it in US, for boatbuilding, but I can't find it in UK
[07:10:21] <CaptHindsight> sawdust, talc and polyester would be low cost
[07:10:39] <CaptHindsight> MEKP for catalyst
[07:11:13] <CaptHindsight> wood based Bondo
[07:12:52] <CaptHindsight> and add minerals to increase the compressive strength
[07:14:58] <MattyMatt> why not use pure mineral + epoxy?
[07:15:22] <MattyMatt> maybe some glass fibre for tensile strength?
[07:15:44] <CaptHindsight> http://www.ebay.co.uk/bhp/polyester-resin-kg + sawdust
[07:16:07] <MattyMatt> with any mineral in it, you won't be using your woodwork tools unless you want them blunted asap
[07:16:13] <CaptHindsight> glass, minerals and wood
[07:16:14] <Jymmm> carbon fiber swarf!
[07:16:21] <Jymmm> diamond dust!
[07:16:37] <Jymmm> Silly Putty!
[07:16:53] <CaptHindsight> but but but wood is natural
[07:16:59] <MattyMatt> diamond has high thermal expansion doesn't it?
[07:17:05] <CaptHindsight> so is the sand
[07:17:08] <Jymmm> so is decomposing flesh
[07:17:09] <MattyMatt> so are diamonds, according to de beers
[07:18:32] <CaptHindsight> aluminum oxide is cheap and almost as hard
[07:19:01] <Jymmm> sodium is natural =)
[07:19:05] <CaptHindsight> recycled sand paper
[07:19:19] <Jymmm> CaptHindsight: that's called sand =)
[07:21:40] <CaptHindsight> polyester resin, sand and saw dust
[07:22:37] <MattyMatt> polyester resin shrinks in curing, but I guess that good for making material rather than precision casting
[07:22:42] <CaptHindsight> call it maker-resin or something else stupid
[07:22:54] <CaptHindsight> that's why you add the sand and sawdust
[07:23:09] <MattyMatt> ah it'd have to be safe in a laser cutter before you could call it maker-crap
[07:23:49] <MattyMatt> hackerspace people love their laser cutters
[07:24:02] <CaptHindsight> sage for children or dogs?
[07:24:08] <CaptHindsight> sage/safe
[07:24:45] <MattyMatt> anyone of a nervous disposition. I think most laser cutters have good extractors tho
[07:24:59] <Jymmm> ?
[07:25:13] <CaptHindsight> the burning wood is natural
[07:25:17] <MattyMatt> hey'd need it with all that acrylic that goes through them
[07:26:41] <Jymmm> what does that have to do with a nervous disposition?
[07:26:42] <MattyMatt> k, time to deplete my plywood stocks, bbl
[07:26:43] <CaptHindsight> like acrylic polyester, epoxy and urethane?
[07:51:24] <einar_> Does anyone know how to invert step signal from USC? For my drives it should be Hi when not active.
[07:52:01] <archivist> USC ?
[07:52:17] <eric_unterhausen> unnamed stepper control
[07:54:28] <einar_> URL: http://pico-systems.com/univstep.html
[07:57:35] <eric_unterhausen> you can do it with hal
[07:59:00] <einar_> How?
[08:02:05] <einar_> If I understand this correctly, the step signals are generated on the USC. But there is no guarantee that I understand anything here.
[08:02:47] <einar_> Flipping them in HAL is only possible if step/dir are generated in software. Or???
[08:04:58] <archivist> I expect you need to read the usc manual to see how to flip
[08:06:52] <einar_> That was what I tried first. But there are a lot of things there I don't understand. :-(
[08:07:23] <einar_> I read this: http://linuxcnc.org/docs/2.5/pdf/LinuxCNC_Integrator_Manual.pdf p.166. I found nothing else.
[08:16:23] <R2E4> With a 3 axis vmc, what would be the bare minimum pushbuttons or controls on a panel you would need?
[08:16:51] <R2E4> E-stop for one
[08:25:32] <R2E4> cycle start, feed hold
[08:25:49] <jthornton> MPG, axis select, jog increment selector
[08:26:05] <jthornton> program start/pause
[08:26:26] <R2E4> I have an mpg, oh yeah, good idea
[08:26:42] <jthornton> great for touching off
[08:27:08] <jthornton> a selector switch for what axis and a selector for jog increments
[08:27:12] <R2E4> most can be momentary I am guessing.
[08:27:29] <jthornton> a rotary works best
[08:27:31] <R2E4> yes yes yes, let me take some notes here.
[08:27:59] <jthornton> I find I use 0.01 for fast jog and 0.001 for final touch off
[08:28:43] <R2E4> well, on my mpg I have some buttons allready, http://irmtl.com/LinuxCNC/VM40/MPG/mpg1.JPG
[08:28:47] * jthornton just created printer friendly pages for his recipes
[08:29:15] <jthornton> are they toggle buttons or momentary
[08:29:20] <R2E4> I am going to cut my first wires today....
[08:29:37] <R2E4> They are momentary
[08:30:55] <R2E4> http://irmtl.com/LinuxCNC/VM40/MPG/mpg.jpg
[08:31:15] <R2E4> I havent connected it so I dont know if that will work, but someone here said it should
[08:31:56] <jthornton> looks like a normal mpg
[08:33:21] <R2E4> pushbuttonms to jog axis with increment selector besides the mpg
[08:33:45] <R2E4> I was thinking feedrate overrides also
[08:33:55] <archivist> I find push buttons for jogging not too good
[08:34:15] <R2E4> archivist: no? Why not?
[08:34:31] <archivist> not the right feel
[08:35:21] <Tom_itx> 12 F
[08:35:37] <archivist> when concentrating on the item the feedback to human matters
[08:35:38] <R2E4> I have rpm meter and load meter for spindle allready and it is coming straight from spindle servo amp.....
[08:35:45] <Tom_itx> high of 16 F today
[08:36:57] <R2E4> I might as well purchase another i/o board or maybe another 7i77 and I can put two daughter boards then.
[08:37:11] <R2E4> I really need to map out my i/o's
[08:39:22] <Tom_itx> anybody see anything i'm missing here: http://tom-itx.dyndns.org:81/~webpage/cnc/configs/sherline/bitfiles/dmesg.txt
[08:39:23] <Tom_itx> ?
[08:40:28] <Tom_itx> R2E4, i considered this bare minimum: http://tom-itx.dyndns.org:81/~webpage/cnc/pendant/pendant2.jpg
[08:43:43] <R2E4> Thats looks cool but http://irmtl.com/LinuxCNC/VM40/IMG_0403.JPG would look funny with 4 buttons on it
[08:44:41] <R2E4> manual ATC operator buttons also
[08:44:44] <Tom_itx> use the current ones
[08:45:14] <Tom_itx> i didn't have any to start with
[08:45:20] <R2E4> The membranes are worn down to throiugh to the actuall buttons
[08:45:39] <Tom_itx> you can have those made
[08:46:00] <Tom_itx> the large pannel or the pendant?
[08:46:44] <R2E4> large panel, I am going to cutout the existing monitor and re fiberglass in a mount for a 19" lcd, then create a button panel below
[08:48:34] <R2E4> Look at these servo's
[08:48:37] <R2E4> http://irmtl.com/LinuxCNC/VM40/IMG_0412.JPG
[08:49:12] <archivist> what no go faster bump to cover it
[08:51:00] <R2E4> The encoders, I dont know what the phaseA and phaseB does from the encoders. Can I leave them off?
[08:51:01] <R2E4> http://irmtl.com/LinuxCNC/VM40/Docs/schematics1.pdf
[08:51:19] <Tom_itx> it's part of the quadrature signal
[08:51:24] <archivist> you need them
[08:52:02] <R2E4> Theres not 8 wires for encoders on the 7i77
[08:52:07] <R2E4> wait
[08:53:53] <Tom_itx> you will probably find phaseA, /phaseA, phaseB, /phaseB to be the case
[08:56:53] <R2E4> like QA0 /QA0, QB0 /QB0 to be the phase a and b, then IDX1 /idx1 as the one rotation signal?
[08:57:15] <R2E4> 6 connectors on the 7i77 for encoders
[08:57:19] <Tom_itx> likely so
[08:59:01] <R2E4> Just have to figure out the drive enable, which I think will end up being the "Velocity Control ON" signal going into the amp
[08:59:29] <R2E4> Once I get LinuxCNC figured out I can connect one axis and try it....
[09:05:05] <Tom_itx> did you find the right driver manuals?
[09:05:33] <R2E4> I have them but are in Japanese. I am getting a translator
[09:06:33] <R2E4> There are three signals I need to know what they are, then I should be good to go
[09:07:07] <Tom_itx> those links didn't help then?
[09:07:32] <R2E4> and the pinouts on the driver connectors, I only have to worry about one connector.
[09:07:59] <R2E4> Not really,
[09:08:48] <Tom_itx> time to go shovel the walk
[09:09:05] <R2E4> Thats what kids are for.
[09:11:09] <R2E4> This is going bye bye!!! http://irmtl.com/LinuxCNC/VM40/IMG_0389.JPG
[09:12:26] <archivist> put those boards on fleabay
[09:12:57] <R2E4> They are selling expensive on fleabay
[09:13:34] <archivist> well they try to get high prices, do they actually sell?
[09:13:35] <R2E4> I allmost forgot... The PLC...... http://irmtl.com/LinuxCNC/VM40/PLC/IMG_0395.JPG
[09:15:35] <R2E4> I could probably keep the relay board and use it for my relays
[09:17:27] <R2E4> take the ribbon cables and break them out on terminals
[09:31:50] <einar_> I'm getting following errors. How can I figure out what parameter is wrong?
[09:34:22] <einar_> And I'm using Universal Stepper Controller.
[09:41:16] <JT-Shop> this a stepper machine?
[09:44:50] <einar_> Yes. It's steppers controlled by Universal Stepper Controller (Pico Systems)
[09:45:28] <JT-Shop> http://linuxcnc.org/docs/devel/html/common/Stepper_Diagnostics.html
[09:45:29] <einar_> So there's a PID involved in it, like with servos.
[09:45:41] <JT-Shop> oh
[09:46:01] <JT-Shop> set your following error high until you tune the PID loop
[10:15:19] * JT-Shop needs to make an adjustable holder for a utility knife blade
[10:42:33] <einar_> Decreasing SERVO_PERIOD seems to help. If that's the right solution, I don't know.
[10:51:12] <pcw_home> Does the USC hal file use a normal PID component?
[11:13:28] <Tom_itx> pcw_home any ideas why after the hostmot2 loads, it all unloads and quits? http://tom-itx.dyndns.org:81/~webpage/cnc/configs/sherline/bitfiles/dmesg.txt this is on 2.6 btw
[11:16:09] <R2E4__> Can I put a 7i72 and a 7i69 on a single 7i77?
[11:20:15] <R2E4___> I got disconnected.
[11:20:38] <R2E4___> Can I put a 7i69 and 7i72 on a single 7i77?
[11:21:16] <eric_unterhausen> tom something else is going on and it's not showing up in dmesg
[11:23:39] <Tom_itx> yeah i didn't see anything unusual there really
[11:24:04] <eric_unterhausen> some hal pin isn't hooked up and lcnc is puking
[11:24:17] <eric_unterhausen> that doesn't make it into dmesg, makes it into lcnclog
[11:24:20] <Tom_itx> it's a working config
[11:24:26] <eric_unterhausen> so says you
[11:24:36] <Tom_itx> it works under 2.5.3 fine
[11:24:51] <eric_unterhausen> are you using 2.5.3?
[11:24:59] <Tom_itx> not for that test
[11:25:14] <Tom_itx> swapped hdd and tried 2.6 with the new TP code
[11:26:31] <eric_unterhausen> u may find the info you want in /home/tom_itx/linuxcnc_debug.txt or /home/tom_itx/linuxcnc_print.txt
[11:26:52] <Tom_itx> i gotta swap hdd then i'll check again
[11:26:59] <eric_unterhausen> sheesh
[11:28:14] <Tom_itx> what? i don't wanna mess up my 2.5.3 install...
[11:29:01] <R2E4___> din terminals are expensive...
[11:29:11] <eric_unterhausen> ebay
[11:29:53] <eric_unterhausen> only problem is that the din terminal accessories that you want are never on ebay
[11:30:25] <atom1> i'm not finding the error log
[11:35:16] <eric_unterhausen> which error log?
[11:36:08] <atom1> the file you suggested i look at
[11:36:42] <eric_unterhausen> ~/linuxcnc_debug.txt?
[11:36:53] <atom1> yeah
[11:37:48] <eric_unterhausen> when linuxcnc shuts down, does it put up an error box with text in it?
[11:38:03] <atom1> ok i found it
[11:38:38] <eric_unterhausen> running linuxcnc over x has some advantages, namely that the debugging stuff is on the terminal
[11:39:03] <atom1> it may have been in the terminal, i didn't look ;)
[11:39:19] <eric_unterhausen> I was about to suggest you enable sshd and log in with ssh and run linuxcnc that way
[11:39:54] <atom1> amongst dos style line ending warnings i get

[11:47:00] <eric_unterhausen> or is it packages?
[11:47:18] <atom1> built it
[11:47:45] <eric_unterhausen> what kernel?
[11:47:53] <atom1> 10.04
[11:51:19] <skunkworks> do the sim configs run?
[11:53:54] <atom1> yeah axis ran
[11:57:00] <atom1> is there a sample config using the parport only?
[11:58:06] <atom1> tried sherline 3axis and it ran
[11:58:19] <atom1> (loaded)
[12:00:09] <atom1> hm2 7i43 big ran as well
[12:01:55] <atom1> are ^^ those errors sections in the ini that may be needed?
[12:03:00] <skunkworks> no - it runs just fine without the ini settings.
[12:03:38] <atom1> i may know what it is
[12:03:58] <atom1> sherline.hal:106: Pin 'hal_manualtoolchange.change_button' does not exist
[12:04:03] <atom1> i'm using a custom file
[12:04:04] <eric_unterhausen> ha, I get those same errors in debug
[12:04:10] <atom1> and it doesn't see it
[12:04:30] <atom1> after a shower i'll comment those out and try again
[12:05:05] <atom1> or can you tell me where to copy the modified file in the master?
[12:05:25] <atom1> bak in a few
[12:06:17] <eric_unterhausen> funny that the actual error isn't in the debug logs
[12:06:42] <IchGuckLive> hi all B)
[12:07:18] <IchGuckLive> !seen psha
[12:07:19] <the_wench> last seen in 2014-01-04 11:02:26GMT 30:48:54 ago, saying Quit: Lost terminal
[12:08:01] <IchGuckLive> can someone tell psha that the logger needs to be added 2014
[12:10:39] <atom1> duh
[12:10:44] <atom1> same pc different hdd
[12:10:49] <atom1> the file isn't on this hdd
[12:11:06] <IchGuckLive> you need to add the configs
[12:11:12] <IchGuckLive> look in the forum
[12:11:30] <IchGuckLive> or update to 2.5.3
[12:11:43] <IchGuckLive> the 7i43 is in there
[12:12:14] <atom1> you talkin to me?
[12:12:20] <IchGuckLive> yes i am
[12:12:28] <atom1> that's not the issue
[12:12:28] <IchGuckLive> reading your logt today
[12:13:12] <atom1> i think i just forgot to copy a file over
[12:13:14] <IchGuckLive> i see you got a warning at startup 25min ago
[12:13:31] <IchGuckLive> is it the std_in.ngc
[12:13:43] <IchGuckLive> or in_std.ngc
[12:14:10] <IchGuckLive> then you need to add the subroutine path to RS inini
[12:26:41] <atom1> it was the custom hal_manualtoolchange file
[12:27:25] <IchGuckLive> ah
[12:27:34] <atom1> i'm not sure where it's looking for the file though
[12:27:40] <atom1> so i can copy the custom one over
[12:27:49] <atom1> i just commented out a line for now
[12:27:53] <IchGuckLive> just delete it in ini
[12:28:01] <IchGuckLive> Hal section
[12:28:02] <atom1> don't want to
[12:28:03] <atom1> :)
[12:28:25] <atom1> i'm running a custom one
[12:28:39] <atom1> but i'd like to copy it over to the master code
[12:28:46] <atom1> not sure where it's at
[12:31:21] <IchGuckLive> psha: logger 2014 ?
[12:32:04] <atom1> what about it?
[12:32:13] <atom1> you want logs for 2014?
[13:28:25] <IchGuckLive> BYE
[13:51:04] <skunkworks> finally install linuxcnc sim on this laptop.. Don't know why I waited so long. works well\
[13:51:13] <skunkworks> (122.04)
[13:51:15] <skunkworks> heh
[13:51:18] <skunkworks> 12.04
[13:51:53] <Tom_itx> skunkworks, are the script files compiled into 2.6?
[13:52:09] <Tom_itx> i tried replacing one with my custom one and it still complained
[13:52:22] <Tom_itx> it's the hal_manualtoolchange script
[13:52:41] <eric_unterhausen> must be path issue
[13:52:45] <Tom_itx> the changes were supposed to be pushed into the new ver but i dunno if that's been done
[13:53:11] <Tom_itx> adds a physical button along side the axis dialog box
[13:53:55] <Tom_itx> i searched for all the matching files and changed the only other one i found
[13:55:15] <Tom_itx> i'm relatively sure that was my error though
[14:03:36] <skunkworks> Tom_itx: I don't know..
[14:04:07] <Tom_itx> i'll do some testing here once i get a chance
[14:04:24] <Tom_itx> i did notice the one in master i found had a .py extension and the other one doesn't
[14:37:43] <JT-Shop> worlds fastest coax stripper made from junk http://gnipsel.com/video/wire-stripper/
[14:38:33] <JT-Shop> Tom_shop, do you see 3 videos on that page?
[14:53:05] <Tom_shop> yes
[14:53:06] <Tom_itx> don't have a viewer for mov though
[14:55:24] <andypugh> Why would you need to strip that much Co-Ax?
[14:55:41] <andypugh> Or are you just harvesting the copper?
[15:04:35] <JT-Shop> yes, someone gave me 8,000' of medical grade coax with copper shield
[15:04:43] <Jymmmm> New uses for all you bearded (men and women alike) folks... http://www.viralnova.com/saved-ducklings-life/
[15:04:55] <Jymmmm> JT-Shop: RG-6 ?
[15:05:29] <Jymmmm> that's a type of coax
[15:05:40] <Jymmmm> it'll be printed on it
[15:06:18] <Jymmm> JT-Shop: might say Belden and a number too
[15:06:27] <Jymmm> or Carol
[15:11:09] <JT-Shop> no marking on the cable
[15:12:03] <Jymmm> Then it's just cheaper bulk stuff more than likely. Pul out the center conductor and I suspect it's copper plated steel (got magnet?) instead of solid copper.
[15:13:19] <Jymmm> RG-6 is fairly good quality 75ohm coax used for cable TV
[15:14:15] <Jymmm> If it had markings on it, I might have bought some of it off you depending on type.
[15:16:08] <JT-Shop> no, it is top of the line medical grade
[15:16:26] <Jymmm> There is no such thing as "Medical Grade"
[15:17:10] <Jymmm> And IF there was, there were be markings on the cable itself to identify it.
[15:17:37] <Jymmm> ...including the LOT# for traceability.
[15:19:31] <Jymmm> Something like this http://thumbs3.ebaystatic.com/d/l225/m/mxq_IHa9E5dwSD0QGWKr3gg.jpg
[15:20:41] <Jymmm> Better example: http://www.jpmsupply.com/media/05/a20791d136a2e43ac87cc9_l.JPG
[15:24:15] <Jymmm> JT-Shop: It's kinda like saying Ti dipped tooling is better than solid carbide (sorta)
[15:28:55] <sivu> so.. is there a gallery of gui configurations
[15:30:27] <MrHindsight> sivu: screen shots or actual config files?
[15:30:43] <sivu> MrHindsight: both would be nice
[15:32:00] <MrHindsight> you can google for the wiki pages with screen shots
[15:32:34] <MrHindsight> http://linuxcnc.org/docs/html/gui/
[15:46:16] <JT-Shop> sivu, the manual comes to mind
[15:46:43] <sivu> yes
[15:47:35] <sivu> i was hoping for a bigger variety
[15:58:19] <Deejay> gn8
[15:59:38] <JT-Shop> the gui section on the forum has some that are not in the manual
[16:00:23] <JT-Shop> or you could just write your own gui http://gnipsel.com/linuxcnc/gui/index.html
[16:45:24] <somenewguy> mesa question folks
[16:45:44] <somenewguy> I have a gecko G540 board and all the digital outputs are fried
[16:45:59] <somenewguy> steppers still work , I just don't ahve my 3 digital outs anymore
[16:46:59] <somenewguy> I was going to buy a second main board sicne its not under warrenty, and for 70 bucks I'd have a spare (machine is operational without digital out)
[16:46:59] <somenewguy> and I'd have output capability, and if I wanted I could have a ~infinite number of inputs for myself to use
[16:47:16] <somenewguy> however mesa boards are cheaper than I thought, and reallllly damn sexy, so maybe I should really buy one of thsoe, but thier website is really written for people who know what they are doing, not idiots like me
[16:58:46] <somenewguy_lap> so before friday I need to figure out if I am buying a spare gecko motherboard, or if I should get a mesa card
[17:02:59] <Tom_itx> mesa has good boards
[17:03:57] <andypugh> somenewguy_home: You might want to look at the 5i25. You can use the 2xG540 config, with one DB25 for the G540 and the other as digital IO.
[17:04:32] <andypugh> (you need a generic parallel port header to bring out the second 25 pins)
[17:06:32] <somenewguy_home> I have parallel ports floating around, they are nice project connectors so thats no issue
[17:06:47] <andypugh> However, you probably really want some kind of protection, so the 7i75 might save you frying any more digital IO. http://store.mesanet.com/index.php?route=product/product&path=69_71&product_id=118
[17:07:02] <somenewguy_home> in my defense, those IO were fried when I got it
[17:07:22] <andypugh> May be an easy fix if it is just the buffer IC.
[17:07:29] <somenewguy_home> I opened it up and thre were no blown components, so I sadly can't fix it on my own, also I can't read the PNs on the chips I am blaming
[17:07:55] <somenewguy_home> I am only just now noticing the 5i25 isn't actually buffered
[17:08:31] <somenewguy_home> so if my gecko main board dies, I would need to buffere hte output of the mesa board still, and then comple it w/ the 4 individual stepper drivers
[17:08:37] <somenewguy_home> so its not super simple
[17:09:16] <somenewguy_home> how hard is it from a software poitn of view, to have 4 gecko stepper drivers running off the mesa 5i25?
[17:09:31] <somenewguy_home> an afternoon of setup, or a couple days of diddling to get it all right
[17:10:23] <Tom_itx> there's probably a config for it already
[17:10:31] <somenewguy_home> wish I had thought of this sooner, leaving on friday so I need to make up my mind soon
[17:10:58] <somenewguy_home> a generic daughter board would be the normal buffer between the mesa pci/pcie card and the gecko stepper drivers?
[17:14:12] <somenewguy_home> ala the 7i76, now to see how much money I am thinking about throwing away "just cause I can"
[17:14:54] <Tom_itx> http://store.mesanet.com/index.php?route=product/product&path=69_73&product_id=215
[17:14:55] <andypugh> You can change from the G540 firmware to the 7i76 firmware if and when it becomes necessary.
[17:15:23] <somenewguy_home> oh the 7i76 actually drives the motors, misread that
[17:15:47] <somenewguy_home> only good to 28v? hmm that can't be right
[17:17:37] <Tom_itx> for driving your drivers
[17:18:17] <somenewguy_home> oh yeah, thats what the manual says
[17:18:29] <somenewguy_home> as I said, very confusing site, and I consider myself good at datasheets...
[17:18:46] <MrHindsight> http://openbuilds.com/ OpenBuilds is a community driven machine/project sharing site that allows people who like to build things to get together and share ideas and the machine designs with everyone
[17:18:59] <Tom_itx> somenewguy_home, it's actually alot better than it was
[17:19:03] <somenewguy_home> for 120 bucks just to isolate my inputs/outputs, doesn't really sound like a good bargain
[17:19:14] <somenewguy_home> for me, i know thats a good price
[17:19:23] <Tom_itx> better than parport by far
[17:19:39] <somenewguy_home> how by far?
[17:19:57] <Tom_itx> the 5i25 clocks the steppers, not the parport
[17:20:00] <somenewguy_home> the 5i25 makes it so my PC is no longer doing step generation, correct? it makes the.
[17:20:02] <somenewguy_home> you beat me to it
[17:20:09] <Tom_itx> it has a much higher clock rate
[17:20:29] <somenewguy_home> and would let me do a servo setup later
[17:20:39] <Tom_itx> with different daughter card
[17:20:46] <somenewguy_home> my 3 year plan includes a full size mill with servos
[17:20:59] <somenewguy_home> and we all know these thigns always go according to plan...
[17:21:11] <somenewguy_home> the 7i76 says it does servos... no?
[17:21:23] <Tom_itx> i'm not that familiar with them
[17:21:28] <somenewguy_home> oh ok
[17:21:36] <Tom_itx> i thought one was for stepper and one was for servo
[17:22:08] <Tom_itx> 7i77 is analog servo interface
[17:22:09] <andypugh> somenewguy_home: Depends on the servos. 7i76 is good for step-dir servos, but for analogue control ones (with encoders) then the 7i77 is the board.
[17:22:25] <somenewguy_home> argh so that would not future proof me...
[17:22:28] <andypugh> The main thing lacking from the 7i76 is encoder inputs.
[17:22:34] <somenewguy_home> that is the only way I could justify this
[17:22:38] <MrHindsight> all the designs seem to be using t-slot as the guide for their linear bearing
[17:22:51] <somenewguy_home> no wait a second, if the 7i76 is basically just a buffer in my setup
[17:23:10] <somenewguy_home> all I need is el-cheapo buffer board between the 5i25 and my geckos for now
[17:23:22] <somenewguy_home> and can purhcase the daughter board my heart desires for any future build
[17:23:25] <somenewguy_home> ?
[17:24:20] <MrHindsight> http://openbuildspartstore.com/ now I see why
[17:24:23] <andypugh> At the moment you don't need anything between the parallel port or the 5i25 and the G540
[17:24:58] <somenewguy_home> the G540 no, but the only way to justify the mesa card is if I can say the mesa will protect me from a "no machine" situation if something bad happens to the G540 main board
[17:25:33] <andypugh> If you get a 5i25 you can connect the G540 and a 7i75, using the 7i75 for the GPIO
[17:25:46] <MrHindsight> http://openbuildspartstore.com/electronics/ featuring 3 USB cnc controllers
[17:26:04] <somenewguy_home> 7i75 is 150 bucks, I can barely justify the original purchase of the mill currently
[17:26:45] <somenewguy_home> that money would be much better spent on a speed controled spindle
[17:26:51] <R2E4____> 7i25 is 119.00
[17:26:56] <MrHindsight> you can smell the quality
[17:27:10] <andypugh> Right, then if that happens you could use the 7i78 ($69) between the 5i25 and generic stepper drives. (or, actually, you could wire direct to the 5i25, just like you can to a parport)
[17:27:58] <somenewguy_home> any idea how much for a daughter board that can directly drive servos?
[17:28:03] <andypugh> 7i75 is $45
[17:28:32] <somenewguy_home> a board that is JUST a buffer is a waste, I could build one for ~30 bucks and that has huge value to me because I need practice laying out circuits and designing pcbs,
[17:28:49] <R2E4____> I think I may have the info to my servo amps, but need clarification.
[17:28:52] <somenewguy_home> meaning I would actually really like to build a plain buffer board as the process of learning it has value to me
[17:29:26] <somenewguy_home> how the heck did I get the wrong prices....
[17:29:27] <Tom_itx> my time is worth more than that
[17:29:36] <andypugh> You can build one for $30 or buy one for $45.
[17:29:37] <R2E4____> would cost more to build one than to buy the 5i25 at 48.00 ....lol
[17:29:38] <somenewguy_home> those are skills I legitmatly need to learn
[17:29:46] <Tom_itx> by the time you get all the nice connectors etc you will have spent more anyway
[17:29:56] <R2E4____> if you dont have all the chems etc boards etc....
[17:30:19] <somenewguy_home> I am in the middle of a startup project and I need to get some decent circuits made for them, so I'd rather get practice on something personal
[17:30:32] <somenewguy_home> if I was just thinking "I can build a board for that" yeah that would be a dumb reason
[17:30:50] <somenewguy_home> and I plan on using my mill to etch teh board
[17:30:59] <somenewguy_home> toner transfer etchign is for the birds, I've done it a few times
[17:31:10] <Tom_itx> it works rather well really
[17:31:30] <Tom_itx> but i've recently sent most of my projects to a chinaman to make for me
[17:31:31] <somenewguy_home> also I will almost deffintly shop out the boards
[17:31:40] <somenewguy_home> yeap tom, you got the right idea
[17:31:53] <somenewguy_home> but I still gotta lay em out
[17:31:58] <somenewguy_home> and a buffer board would be good practice
[17:32:03] <Tom_itx> suit yourself
[17:33:09] <Tom_itx> andypugh do you know if the script files in 2.6 are compiled?
[17:33:13] <R2E4____> http://irmtl.com/LinuxCNC/VM40/servo%20amps/SD_Servo_Amp.pdf item c , is that basically the enable pin? Also item f, WTF is that?
[17:33:44] <Tom_itx> andypugh, i'm getting an error on the hal_manualtoolchange script and tried replacing it in master with my custom one but still get the error
[17:34:18] <Tom_itx> i did notice the one i found in master had the .py extension
[17:34:55] <andypugh> R2E4____: f sounds like the command voltage input
[17:35:45] <andypugh> Tom_itx: Linux uses the #! at the beginning of the file rather than the extension, so just remove the .py from your version.
[17:35:57] <R2E4____> andypugh: thats item a. no?
[17:37:36] <somenewguy_home> So does mesa make boards that actually controll motor voltages?
[17:37:38] <andypugh> Ah, yes.
[17:38:17] <andypugh> somenewguy_home: Not many. Mostly for servo motors. There is a stepper controller, but it is not LinuxCNC compatible.
[17:38:34] <somenewguy_home> what do they have for servos?
[17:38:40] <somenewguy_home> like what do they call it?
[17:38:42] <Tom_itx> leadshine or gecko are probably the best
[17:39:17] <somenewguy_home> I don't intend to buy any stepper drivers
[17:39:25] <somenewguy_home> just trying to understand my upgrade path a bit better
[17:39:31] <andypugh> http://store.mesanet.com/index.php?route=product/category&path=83_90 is a list of all the LinuxCNC-compatible Mesa motor control cards. http://store.mesanet.com/index.php?route=product/category&path=83_90
[17:39:32] <somenewguy_home> oh motion controllers, these are clear
[17:41:28] <somenewguy_home> ok, looks like I'll just limp along for now
[17:41:37] <somenewguy_home> maybe not even get the gecko fixed
[17:43:11] <andypugh> You can consider breaking out the unused IO lines that feed the G540 into your own interface instead.
[17:43:26] <andypugh> Maybe use a ULN2008
[17:47:08] <somenewguy_home> thats the new plan yeah
[17:47:25] <somenewguy_home> I actually already broke them out on the box all my controlls sit in
[17:52:26] <somenewguy_home> the 7i75 sure sounds sexy tho, I might need it for otherthigns anyways, maybe when I make a working buffer board I'll buy one as a reward
[17:52:35] <somenewguy_home> nothing like dangling a carrot infront of yourself, right?
[17:53:40] <somenewguy_home> wait no, it only has 4 inputs like a regular lpt??
[17:53:59] <somenewguy_home> man mesa really needs a "typical application" sketch in thier manuals to save idiots like me from themselvs
[17:54:48] <andypugh> Yeah, the 7i75 is purely a parport-style breakout.
[17:55:05] <andypugh> There are only 17 active pins.
[17:55:12] <somenewguy_home> confusing to say its "designed for use with" thier cards
[17:55:23] <andypugh> The way that the 7i76 adds many more pins is by addressing them serially
[17:55:25] <somenewguy_home> since any pin on a mesa IO card is bidirectional the way I understand it
[17:56:43] <andypugh> Yes, but it is hard to make a buffer bidirectional. (though the GTL2000 manages that magic)
[17:57:02] <somenewguy_home> true, I learened that the hard way, as I had assuemd it was fairly simple...
[17:57:18] <somenewguy_home> but I was expecting like jupmer select or some such
[17:57:45] <somenewguy_home> the 7i75 is best described as a "lpt buffer board" as it will buffer a std lpt port connection
[17:58:02] <somenewguy_home> NOT buffer a 12 pin IO connection
[17:58:15] <somenewguy_home> annoying they refere to pins w/ defined direction as being I/O, rather than what htey are
[18:00:20] <andypugh> If you want a ton of IO and have very deep pockets, you could put the $69 7i74 on the second DB25 header for 8 serial channels, then put 8 digital IO cards on that, say for example 8 x $200 7i64 cards for 192 48V 2.5A outputs and 192 5-24V inputs. Or you could use the much cheaper boards if you don't need 100W per output :-)
[18:01:07] <andypugh> I have a 7i64, it's a lovely card.
[18:01:36] <andypugh> LEDs for all inputs and outputs, drives solenoid valves and contactors directly, etc.
[18:02:12] <somenewguy_home> I think the ULN2008 is obsolete? even findchips doesn't turn it up
[18:02:18] <somenewguy_home> LEDs are a really really nice feature
[18:02:23] <somenewguy_home> they seem silly till youneed them
[18:02:57] <somenewguy_home> I was hoping to find a daughter board that would power servos AND isolate digital IO
[18:03:07] <andypugh> 7i77
[18:03:15] <somenewguy_home> then I could justify buying that in a pinch and use the IO for now, and the servos in the future
[18:03:30] <andypugh> (Well, it won't _power_ servos. It will control servo drives)
[18:04:22] <R2E4____> servo amps are there to power servo's no?
[18:04:59] <somenewguy_home> I thought the 5i25 would do that
[18:05:14] <R2E4____> 7i77 connects to the 5i25
[18:05:15] <andypugh> I <3 Time Machine. I just accidentally deleted the git repo that all my machines share (nfs mounted, physically on the Mac). All I had to do was roll back the backup to earlier in the day, and everything is back :-)
[18:05:16] <somenewguy_home> unless the servo drives are unbufferd then back to square one I gues
[18:05:33] <somenewguy_home> speaking of which I really REALLY gotta get backups setup...
[18:05:39] <somenewguy_home> atleast I finally figured out github
[18:06:23] <somenewguy_home> also ULN2803 I assume is thenewer flavor of the chip you referenced andy
[18:06:37] <somenewguy_home> otherwsie I was looking at ILQ74s
[18:07:03] <somenewguy_home> oh nope, the 2803 is not an isolaator
[18:07:55] <somenewguy_home> woah how did it get so late....
[18:07:58] <somenewguy_home> to the MILL!
[18:24:04] <Loetmichel> re @ home
[19:15:52] <CaptHindsight> anyone recall the brand of mini lathe that Skunkworks was playing with a couple of months ago
[19:16:29] <CaptHindsight> I thought it was larger than a Sherline but maybe I'm wrong
[19:16:33] <jdh> emco
[19:17:05] <andypugh> http://www.lathes.co.uk/emco/page11.html
[19:17:17] <CaptHindsight> http://www.cnccookbook.com/img/OthersProjects/EmcoLathe.jpg like this
[19:18:03] <andypugh> I think they were the Compact5 PC, without the built-in controller
[19:18:19] <CaptHindsight> good size to use for a cnc lens polisher/grinder
[19:18:21] <Tom_itx> wasn't that unimat?
[19:19:36] <andypugh> Emco == Unimat
[19:19:42] <skunkworks> emco
[19:20:00] <skunkworks> right - compact 5 pc
[19:20:28] <Tom_itx> finally, maybe i have a chance now to work on this config
[19:20:31] <jdh> did you sell them all?
[19:20:57] <skunkworks> http://electronicsam.com/images/emco/emcoclose.JPG
[19:21:07] <CaptHindsight> skunkworks: whats the accuracy like on those in good shape?
[19:21:18] <skunkworks> he has sold maybe 6 of them so far.. Sold 3 saturday to a guy from kansas
[19:21:35] <Tom_itx> whereabouts in ks?
[19:21:45] <Tom_itx> maybe i'll go swipe one
[19:22:01] <skunkworks> They are well built - I don't know the spec. the steppers installed will do about .00025 halfstepping
[19:22:15] <skunkworks> Tom_itx: I don't remember - wasn't wichita
[19:22:31] <Loetmichel> they are made in austria iirc
[19:22:42] <Loetmichel> yeas, MUCH better wuality than cHinese
[19:23:14] <andypugh> The bed is still rather narrow for the centre height
[19:24:12] <CaptHindsight> skunkworks: whats the top speed of the spindle?
[19:24:49] <CaptHindsight> http://www.ebay.com/itm/EMCO-UNIMAT-SL-Lathe-Drill-Mill-Grinder-Multitool-115-V-Estate-Sale-mfg-Austria-/161191076350?pt=LH_DefaultDomain_0&hash=item2587bca1fe
[19:25:06] <CaptHindsight> with original factory wood box

[19:27:02] <andypugh> The bar-bed unimats are a bit of a toy
[19:27:54] <CaptHindsight> it would only see polycarbonite and glass
[19:28:06] <R2E4> pncconf: where do you select the mpg? 1st or second?
[19:28:28] <andypugh> http://www.ebay.com/itm/151195523318 is a bit more serious
[19:29:11] <CaptHindsight> a bit much for 90mm plastic
[19:29:56] <andypugh> Maybe sperm whales need contacts?
[19:31:25] <R2E4> found it
[19:33:27] <CaptHindsight> vs http://www.ebay.com/itm/Coburn-Rocket-Lens-Grinder-Model-108BP-115v-1ph-/300380143673?pt=LH_DefaultDomain_0&hash=item45f00d4039
[19:33:57] <atom1> ok fixed it i think
[19:38:51] <atom1> skunkworks, have you tried running anything but sim with this?
[19:40:19] <atom1> MDI tool change doesn't seem to work
[19:46:05] <CaptHindsight> looks like they don't make the small lathes anymore
[19:46:07] <skunkworks> not yet - I was hoping to try it on the emco lathes but have not. (well - I have run it RIP - not simulator...) I don't know which you mean
[19:46:32] <CaptHindsight> http://www.emco-world.us/en/products/industry/turning.html
[19:48:01] <CaptHindsight> looks like I'll have to search in China
[19:48:21] <CaptHindsight> spec grade
[19:48:22] <skunkworks> CaptHindsight: I don't remember - 2500 iirc
[19:49:47] <skunkworks> no - something over 2800rpm
[19:50:11] <CaptHindsight> I'd need a bunch of new ones
[19:50:30] <CaptHindsight> I thought they were still in production
[19:50:56] <skunkworks> I think they make close to the same thing but it is a slant bed
[19:51:46] <atom1> skunkworks, i set this up with my configs and it runs the axis ok
[19:51:55] <atom1> mdi tool change doesn't seem to work
[19:52:05] <CaptHindsight> http://www.alibaba.com/product-gs/1174285494/linear_motor_dc_12v.html must be one of those rotary linear motors :)
[19:54:35] <andypugh> it's just possible that the shaft moves in and out not round and round
[19:54:56] <CaptHindsight> http://www.alibaba.com/product-gs/587262818/linear_positioners_KTC50mm_2500mm.html
[19:54:59] <jdh> and it's explosion proof
[19:56:44] <CaptHindsight> Commutation: Brush and explosion proof
[19:56:50] <andypugh> "Explosion Proof" means it won't ignite gas.
[19:57:10] <CaptHindsight> sealed or bullshit?
[19:57:13] <andypugh> Not normally associated with brush commutation though.
[19:57:16] <jdh> I'd go with BS
[20:01:06] <atom1> skunkworks, what's the difference between SIM and RIP?
[20:02:41] <atom1> i noticed that spiral test has no tool associated with it
[20:02:51] <andypugh> SIM doesn't compile any hardware drivers, RIP is a self-contained installation in a directory, rather than one installed in /usr/bin
[20:03:14] <atom1> ok
[20:03:15] <andypugh> You can actually compile something that is SIM _and_ RIP
[20:03:27] <atom1> but it will run gcode?
[20:03:34] <andypugh> yes
[20:03:58] <atom1> i was testing this out a bit but MDI toolchange doesn't wanna work
[20:04:22] <andypugh> I don't even know what you mean by "MDI toolchange"
[20:04:46] <atom1> typing a T1 M6 G43 in the MDI dialog
[20:05:10] <andypugh> which config?
[20:05:22] <atom1> my sherline config from 2.5.3
[20:05:44] <CaptHindsight> http://gmbearing.en.alibaba.com/productgrouplist-214696341/CNC_Machine_Units.html
[20:05:50] <andypugh> Does that use hal_manualtoolchange?
[20:07:03] <andypugh> CaptHindsight: They sell "Corss Roller Linear Guides With Good Qulaity and Price"
[20:07:25] <atom1> yes
[20:07:39] <andypugh> Is the dialog box hiding?
[20:08:08] <CaptHindsight> they nead a beeter spel cheker
[20:08:26] <atom1> but i also copied my modified ver of it so lcnc would run with my config
[20:08:35] <atom1> the dialog box isn't hiding
[20:08:51] <atom1> it allows entry but doesn't execute it
[20:09:06] <andypugh> Is the tool_changed pin being asserted?
[20:09:26] <atom1> it does depress the pause button in axis
[20:09:36] <atom1> lemme check
[20:10:39] <atom1> no
[20:11:04] <atom1> no activity on any of the toolchange vars
[20:11:21] <CaptHindsight> http://gmbearing.en.alibaba.com/product/671455763-214696341/Linear_Actuator_With_Good_Quality_And_Price.html not many suppliers of complete units like these in China
[20:11:23] <andypugh> Sounds like a net problem, or your toolchange code is borked
[20:11:25] <atom1> hal_manualtoolchange.number is 1
[20:11:46] <atom1> it's the mod that was supposedly pushed to master
[20:12:03] <atom1> to add the physical button
[20:12:39] <andypugh> are the tool change request and complet pins netted?
[20:13:00] <atom1> yeah
[20:13:18] <atom1> net tool-change iocontrol.0.tool-change => hal_manualtoolchange.change
[20:13:18] <atom1> net tool-changed iocontrol.0.tool-changed <= hal_manualtoolchange.changed
[20:13:18] <atom1> net tool-change-number iocontrol.0.tool-prep-number => hal_manualtoolchange.number
[20:13:18] <atom1> net tool-prepare-loopback iocontrol.0.tool-prepare => iocontrol.0.tool-prepared
[20:14:14] <andypugh> Is iocontrol.0.tool-change showing any activity?
[20:15:01] <atom1> no
[20:15:12] <atom1> brb
[20:15:20] <andypugh> (workaround, if you don't actually care about tools really). M61 Q1 G43 H1
[20:16:16] <CaptHindsight> http://www.alibaba.com/product-gs/743243236/Reliable_manufacturer_Beijing_Seigniory_efficient_CNC.html?s=p just add your own table
[20:16:38] <CaptHindsight> comes with FastCAM?
[20:17:56] <CaptHindsight> hey tjtr33
[20:18:05] <tjtr33> damn its cold!
[20:18:14] <CaptHindsight> heh
[20:19:17] <atom1> andypugh, the idea was to be able to do hardware tests on the new TP code
[20:19:29] <atom1> so tool changes would play into that
[20:19:47] <CaptHindsight> looks like it won't be quite as cold as expected, only -20F
[20:19:59] <andypugh> So, M61 will load a tool, without actually triggering a tool change.
[20:20:00] <atom1> i'll try it with the original toolchange script and see if it matters
[20:20:33] <andypugh> Night all
[20:20:36] <atom1> just a matter of commenting out my button line
[20:20:38] <atom1> later
[20:20:38] <tjtr33> CaptHindsight, have servos been used with BBones? ( i only find the toy rc airplane 'servos' mentioned )
[20:20:41] <tjtr33> night andy
[20:21:14] <CaptHindsight> tjtr33: did you ever come across a taiwan supplier of linear positioners with lesser than Hiwin quality?
[20:21:45] <tjtr33> no, i bought a used SMAC voice coil and amp tho
[20:22:00] <CaptHindsight> better than drawer slides but not aerotech
[20:22:17] <CaptHindsight> how did that coil turn out?
[20:22:28] <CaptHindsight> enough torque?
[20:23:00] <tjtr33> try Star? their salesmen thoguht they were gresat ( fwiw :)
[20:23:34] <tjtr33> the units on the bench, got a 48V p/s from Mr Kee Ling ( aka automation mumble )
[20:24:03] <tjtr33> haha im a terrible typist w/o frostbit fingers :)
[20:24:20] <CaptHindsight> maybe something like bolt on makerslide that has been precision ground
[20:26:13] <tjtr33> the postion of the electrode is pretty tight, the process is changes a lot with with 10um position change,
[20:26:32] <tjtr33> so 'sloppy' to me is not everyone else's measure
[20:27:08] <CaptHindsight> I'd like the precision but without the durability
[20:27:57] <CaptHindsight> and lower cost
[20:28:03] <tjtr33> i think I'm kinda stuck with a few suppliers, but if you describe something you want, I know Purch agents for cnc builders in TW
[20:29:05] <tjtr33> makerslide is a copy of ... carrlane idea... no Bishop wisecarver
[20:31:37] <tjtr33> http://www.bwc.com/products/dual-vee.html
[20:31:53] <tjtr33> makerslide should know that BW's had these for a long time
[20:32:17] <CaptHindsight> makerslide was a joke, he acts like he invented extrusions
[20:34:53] <tjtr33> has anyone used servos ( ac/dc with encoder feedback ) on a BeagleBone? seems devs are step-centric
[20:35:42] <CaptHindsight> not with the Bone, I'm going to try servos with the cubieboard soon
[20:36:22] <tjtr33> ooh ooh mr kotter, lemme know about that. I got a Qb here too
[20:36:42] <CaptHindsight> I wish the BBB had a GPU to support a UI
[20:37:56] <CaptHindsight> andy got his imx6 + arduino board, so there could be more ARM boards to play with soonish
[20:38:36] <CaptHindsight> http://liliputing.com/2013/04/udoo-109-single-board-computer-is-like-an-arduino-crossed-with-a-raspberry-pi.html
[20:39:48] <CaptHindsight> http://www.kickstarter.com/projects/435742530/udoo-android-linux-arduino-in-a-tiny-single-board/posts/456046
[20:40:02] <atom1> ok, running a gcode file the toolchange works however using the MDI window it doesn't
[20:40:08] <tjtr33> so udoo _is_ imx6, by freescale. cool
[20:40:29] <CaptHindsight> yeah with an Atmel SAM on the same board
[20:40:40] <CaptHindsight> http://www.udoo.org/
[20:41:39] <CaptHindsight> we are going to try and get the FPGA anything IO card working with the cubie
[20:42:28] <atom1> sounds like fun
[20:42:31] <tjtr33> urgh urf oog you segwayed into Mesa land with another holy grail best of luck, maybe i can help somehow
[20:43:07] <CaptHindsight> http://hardkernel.com/main/products/prdt_info.php another ARM board that might be worth supporting since it has a decent GPU
[20:43:08] <tjtr33> atom1 sorry dont knwo why your MDI didnt work while gcode file did
[20:43:25] <atom1> this is 2.6 i'm testing
[20:44:23] <tjtr33> hmmm when 58$USD is 79000 of the other countries money...
[20:45:04] <ChuangTzu> it's arbitrary...
[20:45:12] <ChuangTzu> CaptHindsight: i'm still looking for a mill btw :)
[20:45:27] <ChuangTzu> i'm hoping the market will pick up now that the holidays are done
[20:45:30] <CaptHindsight> there were a bunch on ebay
[20:45:55] <ChuangTzu> nothing caught my fancy i guess
[20:46:01] <ChuangTzu> i've been looking at least twice a week
[20:46:19] <CaptHindsight> lots of CNC lathes
[20:46:29] <CaptHindsight> <$5K
[20:46:50] <ChuangTzu> cnc lathe is a bit further down on my list
[20:48:06] <atom1> CaptHindsight, which of the 3 variations are you looking at on that board?
[20:48:22] <CaptHindsight> atom1: which board?
[20:48:32] <atom1> the udoo
[20:48:39] <ChuangTzu> i checked out that Tree 325 in mundelein but the dude was asking too much
[20:48:49] <CaptHindsight> http://www.ebay.com/itm/161186776549
[20:49:05] <CaptHindsight> but California
[20:49:37] <CaptHindsight> atom1: andypugh just got one, waiting for some feedback from him first
[20:49:49] <ChuangTzu> yeah, i've seen a bunch out west
[20:49:55] <atom1> do you know which he got?
[20:50:23] <atom1> single dual or quad?
[20:50:37] <tjtr33> ChuangTzu a Tree? so bridgeport sized? maybe ask Igor Chudev ( linuxcnc user in Chi area , also used machinery dealer )
[20:50:45] <skunkworks> CaptHindsight: I think this is the current 'compact 5'

[20:51:10] <atom1> skunkworks, there's something odd about tool changes with this code
[20:51:20] <CaptHindsight> http://www.ebay.com/itm/261299862995
[20:51:48] <skunkworks> atom1: there could be... what does it do?
[20:52:22] <skunkworks> (this is pretty new code - he has re-writen it in just a few months)
[20:52:24] <atom1> running gcode it does a regular toolchange and the dialog box comes up but in the MDI window nothing happens
[20:52:50] <atom1> check halconfig and no activity there either
[20:53:05] <skunkworks> might want to explain it on the devel list - circular blend thread
[20:53:39] <atom1> i don't think i've ever been on the list :)
[20:53:53] <skunkworks> does it work in 'normal' master?
[20:54:03] <atom1> haven't tried that
[20:54:12] <atom1> how would i recompile for that?
[20:54:56] <skunkworks> I would just pull master into a new directory and build.
[20:55:02] <atom1> ok
[20:55:20] <skunkworks> then you can switch between the two - that is what I do to compare the performace between the two
[20:55:36] <CaptHindsight> http://www.ebay.com/itm/Hurco-KMB-I-CNC-Mill-Used-AM12099-/121238145729?pt=LH_DefaultDomain_0&hash=item1c3a5b4ac1 Hurco KMB-I $1995
[20:56:20] <ChuangTzu> hmm
[20:56:48] <ChuangTzu> they'll load it too
[20:56:51] <ChuangTzu> with tools
[20:57:36] <CaptHindsight> I might be headed that way to pick up a router
[20:58:11] <ChuangTzu> you have a truck?
[20:58:16] <tjtr33> the Hurcos's nicer than the de-capitated SB
[20:58:33] <tjtr33> and you get tapping head

[20:58:55] <Jymmm> NIMS https://www.nims-skills.org/web/nims/home
[20:59:07] <CaptHindsight> PRATT & WHITNEY "BEAVER V5"
[21:00:45] <tjtr33> Pratt has Heidenhain control clean too
[21:01:08] <ChuangTzu> hurco is cheap and comes with goodies
[21:02:22] <ChuangTzu> and that awesome computer
[21:02:39] <tjtr33> http://www.mohawkmachinery.com/callprocessing/quoteview.asp?sequipmstid=88361 better pix
[21:02:58] <CaptHindsight> http://www.ebay.com/itm/370729400325 I was also looking at this
[21:03:49] <skunkworks> so - I was standing in front of my laptop the other day - I was resting my elbow on the corner of it... It made a squealing noise.. Took me a second to figure out it was my laptop. I though - I don't remember the fan being there... oh well.
[21:04:13] <skunkworks> today I did it again - and it dawned on me when my laptop locked up - that the hd was under my elbow...
[21:04:28] <CaptHindsight> ouch
[21:04:30] <tjtr33> eeesh
[21:04:41] <skunkworks> needless to say I am copying everything off of it. (working at the moment)
[21:04:46] <tjtr33> backup backup bcakup
[21:05:07] <skunkworks> sure - I really would not have lost anything important. just an inconvenience.
[21:05:29] <tjtr33> hope you're warm enuf, i figger its worse up north than in chicago
[21:05:48] <tjtr33> i'm cranking the car over now to make sure
[21:05:51] <CaptHindsight> takes me maybe 3 hours to restore my Linux systems, 3-5 days for win7
[21:06:05] <jdh> 64F here
[21:06:18] <CaptHindsight> <-- parks indoors
[21:06:24] <skunkworks> -6F at the moment..
[21:06:32] <CaptHindsight> 58F in the shop
[21:06:42] <jdh> geez... people live like that?
[21:07:48] <CaptHindsight> 53F in Nanjing but I'm stuck here
[21:08:01] <tjtr33> i got email from buddy in Kph Phanagn today, he's coming back to skokie, i told him dont! kick a cop or something, anything but dont come now.
[21:08:08] <tjtr33> Koh
[21:08:16] <somenewguy_chips> CaptHindsight: souns about right
[21:08:49] <somenewguy_chips> I remember in like 05 or so when linux officially became the eaieer install than windows for a non-technical person...
[21:08:54] <somenewguy_chips> and the gap has only gorwn
[21:08:56] <somenewguy_chips> grown
[21:09:32] <somenewguy_chips> skunkworks: I think its about time for you to buy a lottery ticket
[21:09:42] <ChuangTzu> i bike to work
[21:09:52] <ChuangTzu> going in tomorrow. fuck what they say
[21:09:53] <CaptHindsight> how far?
[21:09:57] <ChuangTzu> 7 mi each way
[21:09:59] <somenewguy_chips> bike commute for ever!
[21:10:00] <tjtr33> i thought you were in Chi
[21:10:02] <ChuangTzu> i am
[21:10:15] <CaptHindsight> ^^ south sider
[21:10:18] <ChuangTzu> yup
[21:10:31] <tjtr33> wear a mask so you dont freeze your lungs
[21:10:44] <ChuangTzu> it's not even going to be that cold. i don't know why everyone is freaking out
[21:10:53] <somenewguy_chips> how cold?
[21:10:55] <ChuangTzu> -10f
[21:11:00] <somenewguy_chips> hahah
[21:11:06] <CaptHindsight> I'm just tired of cold and snow already is all
[21:11:16] <CaptHindsight> yeah -20F, been there
[21:11:17] <tjtr33> not as cold as predicted but not healthy fer sure
[21:11:26] <somenewguy_chips> I'm tired of the damn snow getting into the shop...
[21:11:31] <ChuangTzu> yeah, it's a pain
[21:11:33] <somenewguy_chips> freaking water damage
[21:11:43] <somenewguy_chips> previous owners were hippies and useless I guess
[21:11:52] <ChuangTzu> but at least when it's -10, even the salt water freezes so i don't have to deal with all the muck on my bike
[21:12:00] <ChuangTzu> the muck is the worst
[21:12:03] <somenewguy_chips> or squirrels, I have not ruled out squirrels at this point
[21:12:07] <somenewguy_chips> salt muck
[21:12:09] <CaptHindsight> back in the 80's this would be about the time my trans or clutch would need to replaced in the snow
[21:12:14] <ChuangTzu> heh
[21:12:20] <somenewguy_chips> I thought my bike was covered in snow and ice
[21:12:23] <tjtr33> haha busting ice-cicles off gutter, filling them with salt & laying out heater cables today
[21:12:34] <somenewguy_chips> then when my hands went all dreid out slug on me, I realized what I was cleaning up...
[21:13:03] <ChuangTzu> i wish they'd stop salting
[21:13:07] <ChuangTzu> and use sand/gravel instead
[21:13:20] <CaptHindsight> won't happen here
[21:13:27] <tjtr33> yeh, better idea, just hard to clean up
[21:13:34] <ChuangTzu> they have trucks that suck it up
[21:13:37] <ChuangTzu> basically street cleaners
[21:13:43] <ChuangTzu> so you can reuse like 90% of it
[21:13:48] <CaptHindsight> I think they use sand up in Milwaukee
[21:13:56] <tjtr33> elgin street sweepersw ( yay elgin illinois :)
[21:14:11] * ChuangTzu spent 3 winters in finland
[21:14:35] <CaptHindsight> so you're no stranger to cold
[21:14:52] <tjtr33> stranger to the sun tho
[21:15:01] <ChuangTzu> depends on the time of year
[21:15:13] <ChuangTzu> land of the midnight sun in the summer
[21:15:31] <ChuangTzu> i forgot to mention that i was there for 3 summers too
[21:15:39] <CaptHindsight> mosquito free?
[21:15:40] <ChuangTzu> i think andypugh goes there every winter too
[21:15:46] <ChuangTzu> up in lapland
[21:16:03] <ChuangTzu> yeah, mosquitos stopped biting me sometime when i lived in florida
[21:16:06] <CaptHindsight> he said Minnesota or canada this year
[21:17:04] <CaptHindsight> if i wasn't so busy I'd go to CES this week
[21:17:18] <ChuangTzu> oh, i forgot about that
[21:17:22] <CaptHindsight> must be in the 70's there
[21:17:24] <ChuangTzu> usually we send people there with some displays
[21:17:53] <CaptHindsight> wow they are only in the 50's
[21:19:09] <CaptHindsight> Come visit for the frosbite and stay for the gang wars
[21:19:14] <ChuangTzu> heh
[21:19:30] <CaptHindsight> and blues
[21:29:35] <atom1> skunkworks, master does the same thing
[21:29:53] <CaptHindsight> do people buy oscilloscopes and not know how to fix them? I was surprised by how many questions are on the forums about scope issues
[21:32:15] <ChuangTzu> hmm, i wish i had a scopt
[21:32:24] <atom1> however master did have the modified hal_manualtoolchange in it
[21:32:46] <skunkworks> atom1: ah
[21:33:03] <atom1> i wonder if his ver overwrote that
[21:33:42] <skunkworks> I would guess it is a change in master that doesn't work the same as 2.5 or whatever you run normally
[21:34:32] <atom1> odd it works ok running gcode
[21:35:15] <skunkworks> you will have to explain the issue to someone in the know..
[21:35:30] <atom1> where would i do that?
[21:36:12] <skunkworks> either the mailing list, post a bug on source forge or get on linuxcnc-devel and ask.. (although 1 or 2 is proably the best)
[21:36:14] <atom1> -devel?
[21:36:25] <skunkworks> give it a shot
[21:37:31] <atom1> i'll try a few things here first
[21:52:06] <R2E4> Can I get some help with an mpg?
[21:52:51] <R2E4> with a 7i77, it says input 16, 17, 18, 19 you can use mpg, when I use pncconf there is no input selection for mpg.
[21:53:04] <CaptHindsight> ChuangTzu: lots on ebay with minor issues. I just picked up 2 that just needed the self calibration util run
[21:53:21] <CaptHindsight> <$200
[21:59:12] <somenewguy_chips> exit
[21:59:19] <eric_unterhausen> I have a nice scope, but it's 3 times the size of a decent scope of current vintage
[22:06:56] <pcw_home> R2E4: you need to set the sserial mode to 3 to have the MPG option available
[22:06:58] <pcw_home> (though I dont know if this is supported in pncconf) If not supported you will have to add the
[22:06:59] <pcw_home> MPG plumbing in the HAL file yourself
[22:11:27] <tjtr33> CaptHindsight, that Pratt mill has Heidenhain TNC 155 with 1 or 5um analog scales. those are the only 2 poss rez for that control
[22:20:23] <tjtr33> i _think_ it has a manual toolchanger (chuck) using a foot switch ( from pix & wiring diagrams )
[23:32:46] <CaptHindsight> http://tinyurl.com/le3ph4x why two wheels on the top? fine and coarse Z?
[23:48:28] <archivist> one may be a locking handle
[23:52:37] <RyanS> I was watching some videos of closed die forging. Fascinating stuff , but the example 10, 20T (?) machine appeared completely devoid of guards or safety features. I've seen paper guillotines, with more safety features!
[23:53:20] <RyanS> Like double hand switches and laser proximity switches
