[00:00:20] <asdfasd> drive microstepping also 1
[00:00:56] <asdfasd> and motor steps per rev, you can enter the calculated step per mm for your machine
[00:01:29] <Tom_itx> the pulley ratio can be calculated from the teeth

[00:05:21] <asdfasd> oh sorry you are doing in inches

[00:12:00] <djdelorie> could you set your screw pitch to *be* the "inches per revolution", and leave the steps/rot alone?
[00:12:53] <djdelorie> i.e. with a 5 tooth/in belt, and a 20 tooth gear, that's 4in per rot. Set your "screw" to 1/4 TPI (not 1/4" pitch) ?
[00:19:36] <jdhnc> end up the same.
[00:20:26] <mrsun> i set my screwt o 2mm lead (im metric), steps to 200 (my steppers has 200 steps/rev) and microsteping to wahtever microstepping i have
[00:20:30] <mrsun> gear ratio 1:1
[00:20:48] <mrsun> as im directly coupled to the leadscrew
[00:22:51] <djdelorie> leadscrews are easy, just fill in the numbers. It's timing belts that are tricker
[00:23:09] <asdfasd> I think you can do the same with timing belt
[00:23:29] <asdfasd> you can enter these 45mm as pitch
[00:24:19] <asdfasd> but finally is calculated as steps per unit, and then entered in ini file
[00:27:04] <Tecan> to print the emc logo it keeps saying that its going to hit my limit switch.. gaa
[00:27:36] <Tecan> should home switch location be negatice or the table travel ?
[00:28:25] <asdfasd> depends of your machine configuration

[01:11:48] <Tecan> how come the spindle wont turn off when done ?
[01:11:58] <Tecan> the pwm keeps comming
[01:12:08] <Tom_itx> did you tell it to shut off?
[01:12:32] <Tom_itx> M5
[01:12:32] <Tecan> no but i turned everything on without my special glasses
[01:13:29] <Tecan> how do i tell it that ?
[01:13:37] <Tecan> i see the mdi command box
[01:14:10] <Tom_itx> there should be a spindle on off button there somewhere iirc
[01:14:34] <Tecan> hmm it was already pushed in
[01:14:56] <Tom_itx> maybe your logic is backwards
[01:15:19] <Tom_itx> i had to invert most of mine

[01:18:24] <Tecan> then it says speed 1 and pwm 1
[01:18:30] <djdelorie> pulse dithering mode?
[01:18:37] <Tecan> weird
[01:19:21] <Tecan> pulse density modulation
[01:32:40] <Tecan> well it worked
[01:32:52] <Tecan> went through like 5 sheets of paper

[02:10:50] <WillenCMD> does anyone know if anyone has had luck using the altera cyclone 2?
[02:12:42] * djdelorie is a xilinx guy...
[02:14:03] <WillenCMD> yes but cost is a issue, mesa cards are great but the cyclone ii is a fourth the price
[02:14:04] * pfred1 wants multiple cursors
[02:14:25] <pfred1> how come we only have one?
[02:14:36] <pfred1> we have 2 hands
[02:15:18] <WillenCMD> screw a mouse, i want to use my mind
[02:15:31] <pfred1> I seen that in a store once
[02:15:39] <WillenCMD> i watched a tv show about it
[02:15:42] <pfred1> this band yo ustrapped to your head
[02:16:17] <WillenCMD> using it on paralyzed patients, takes a long time to calibrate, but it maps brain wave changes
[02:17:55] <pfred1> computers have rendered me effectively paralyzed anymore
[02:18:12] <pfred1> I sit in front of them long enough I might as well be
[02:18:56] <djdelorie> One expects gaming accessory stores to start offering catheters for gaming chairs, so you never have to get up...
[02:19:25] <pfred1> nah you need the idiocracy easy chair with a flush handle on the side
[02:19:29] <WillenCMD> i solved that, i just married a nurse
[02:19:49] <pfred1> go away 'batin!
[02:19:53] <WillenCMD> iv fluids, plus cath= gaming 24/7

[02:20:45] <WillenCMD> emc2 24/7 == divorce also, it gets lonely in my basement
[02:21:06] <WillenCMD> good thing i use virtual machine for developing and testing
[02:22:02] <WillenCMD> i hooked an ip-cam up to my mill so i can monitor long gcode runs without disturbing the emc2 computer :)
[02:22:38] <pfred1> I almost bought a webcam at the flea market yesterday
[02:23:16] <WillenCMD> i unhooked the ir, wired it to a relay, and i can toggle the estop via the web interface

[03:00:16] <Tecan> i only have x and z
[03:01:39] <djdelorie> lie to it :-)
[03:02:15] <Tecan> why when the source code is there
[03:02:56] <djdelorie> you have to add the lie-to-me option to the sources :-)
[03:03:35] <djdelorie> are you using a slice through an image to run a lathe?

[04:13:45] <Thadius1> working on cnc mill
[04:13:54] <Tecan> you like to party ?
[04:14:02] <Thadius1> back in my youth lol
[04:14:14] <Thadius1> not so much anymore

[04:14:56] <Tecan> not a run of the mill party though
[04:15:05] <Tecan> this'll be epic mill party
[04:16:07] <Tecan> i think the laser is making me blind
[04:16:31] <djdelorie> do not look into laser with remaining eye
[04:16:57] <Tecan> even looking at the burning part with protective glasses on
[04:17:04] <Tecan> things get blurry after
[04:17:45] <Thadius1> man, ordering all my stuff tonight
[04:17:58] <Thadius1> v90, spindle, software, ect ect
[04:18:24] * djdelorie is putting together a shopping list for lathe accessories...
[04:18:56] <djdelorie> the tricky part is matching up modern accessories with a 90-year-old lathe
[04:19:03] <Thadius1> yikes
[04:20:16] <djdelorie> this thing even predates threading dials ;-)
[04:25:37] <Tecan> who does python here ?
[04:25:59] <Tecan> im trying to find from rs274.author import Gcode
[04:26:13] <Tecan> need to make image to gcode run standalone

[09:58:05] <JaggedNZ> Random question of the day: does EMC always send a fixed length pulse to STEP ?
[09:58:52] <mhaberler> man stepgen: stepgen.N.steplen u32 rw
[09:58:53] <mhaberler> The length of the step pulses, in nanoseconds. Measured from rising edge to falling edge.
[09:59:24] <mhaberler> thats a parameter, so fixed at config time
[10:01:02] <mhaberler> no, wrong: it can be changed post config
[10:02:17] <JaggedNZ> hmm cool, thats what I was hoping for. Copied some stepper MCU code that polls rather than using interupts
[10:02:45] <JaggedNZ> couldn't figure out how it would work unless pulse times where near identical
[10:03:23] <mhaberler> yout should be able to scope it with halscope even in sim, and then fiddle with setp stepgen.X.steplen <length>

[11:56:57] <Loetmichel> i meant: the whole machine is SO silent i even let the door of the worksop open and my wife 2 rooms away doesent complain!
[11:57:12] <Tecan> neat
[11:57:48] <Loetmichel> yes, and cheap
[11:58:13] <Loetmichel> have payed about 250 eur fpr spindle plus VFD plus set of ER11-chucks
[12:22:29] <Jymmm> Loetmichel: What up with you bouncing for a couple hours?
[12:41:57] <ssi> I need a pendant
[12:42:37] <ReadError> me too ssi
[12:42:41] <ReadError> order 2 and give me one plz
[12:43:16] <ReadError> what kind of tools should i go ahead and order
[12:43:21] <ReadError> in preparation for the machine
[12:43:22] <ssi> for what
[12:43:30] <ssi> the taig mill?
[12:43:30] <ReadError> i need the vactara oil
[12:43:33] <ReadError> yessir
[12:43:51] <ssi> measuring tools, setup stuff
[12:43:55] <ssi> do you have a vise for it?
[12:43:59] <ssi> clamping set?
[12:44:02] <ssi> 123 blocks
[12:44:11] <ssi> parallels for the vise
[12:44:19] <ssi> I don't really have a feel for just how tiny the taig is :)
[12:44:31] <ssi> also, what exactly do you intend to cut
[12:47:09] <ReadError> aluminum mostly
[12:47:11] <ReadError> no steel
[12:47:14] <ssi> what sort of parts
[12:47:22] <ReadError> pcbs
[12:47:34] <ReadError> motor mounts for some quad copters
[12:47:46] <ReadError> i need a nice table to hold larger parts
[12:47:50] <ReadError> not so much a vise
[12:49:18] <ReadError> maybe i can get some of those little hold down clamps
[12:49:24] <ReadError> and use a piece of wood
[12:49:33] <ReadError> i dont want to tear up my board learning
[12:52:44] <ReadError> idealy i would like to make a router to cut my CF on
[12:52:58] <ReadError> but i figured with a mill making a router would be more feasible ;0
[12:53:18] <ssi> it helps
[12:54:37] <ReadError> i was thinking about using some 80/20

[13:31:14] <SolarNRG> But CNCs use much more powerful stepper motors
[13:31:39] <SolarNRG> And to switch them very very fast you need like a gecko drive which only uses parallel
[13:32:40] <SolarNRG> I think when switching at very high frequency, USB breaks down because it is a packet switching thing, wheras parallel you are not

[14:29:54] <CareBear\> a local CPU bus is also not realtime
[14:30:05] <CareBear\> all communication has latency

[14:37:33] -!- psha [psha!~psha@] has joined #linuxcnc
[14:37:57] <CareBear\> the key for successful USB living is to use a bit more high level communication over the bus, ie. having some bit of control outsourced to a moderately or highly intelligent peripheral, e.g. an axis controller
[14:40:36] <skunkworks> so 'motion' would be in the usb device/

[17:20:08] <Jymmm> jthornton: Or, if they give you any shit, have them send you in writting that the equipment is under warranty and will be repaired/replaced at no cost to you including all shipping fees.
[17:20:59] <asdfasd> is there any way I can make a box in pyvcp, and pressing a button to send the value in the box as MDI command and then zero that box
[17:21:20] <Jymmm> There is a "durable goods" law in the US that says leased/rent should be working, so that "warranty" policy is BS
[17:23:47] <Jymmm> jthornton: And since it's a "one time accoutn setup fee of $150", never close the account, just have it placed on hold for 6months or indefinantly if you ever decide to change/move and may want it again in the future.

[17:30:30] <ssi> jthornton: hey I have a question for you about the toolchange ladder
[17:30:45] <ssi> jthornton: occasionally mine misses a change... it seems like it's popping the stop a little too early
[17:30:53] <ssi> jthornton: is that something I can fix in ladder, or do I need to tweak the encoder magnet
[17:31:12] <jthornton> the encoder magnet might be a little off
[17:31:23] <jthornton> or the stop may be sticky
[17:31:42] <ssi> I can often hear it clack a little as it runs past the last tool before the selected one
[17:31:50] <ssi> and occasionally it'll actually stop at the one before selected
[17:31:52] <jthornton> my stop is sticky after it sits for a day or three and I always miss the first tool but not after that
[17:32:00] <ssi> sometimes it faults the program, sometimes it DOESNT.... which is scary
[17:32:12] <jthornton> yea the magnet timing may be a bit early

[19:56:42] <Loetmichel> anyone knows how to convert tooth spacing in european Module in gears?
[19:57:06] <djdelorie> today's lesson: if you're using tabs/tags to hold your workpiece in while you profile it's outline, make sure your Z is touched off the BOTTOM of the piece. Tags don't work if they're not there because your Z is wrong :-P
[19:59:26] <Loetmichel> hrhr
[20:03:06] <archivist> asdfasd, have you been attempting to tap with mach3?
[20:05:29] <asdfasd> Loetmichel: Im not sure if that will help you - copy from wiki
[20:05:32] <asdfasd> Countries which have adopted the metric system generally use the module system. As a result, the term module is usually understood to mean the pitch diameter in millimeters divided by the number of teeth. When the module is based upon inch measurements, it is known as the English module to avoid confusion with the metric module. Module is a direct dimension, whereas diametral pitch is an inverse dimension (like "threads per inch").

[20:35:22] <ssi> since I have a spare 7i33
[20:35:37] <ssi> want to do 23 frame x/y motors and a 34 frame Z motor
[20:36:09] <jdhnc> the cncfusion g0704 kit has a 23 Z mount
[20:36:09] <cradek> pico makes an inexpensive pwm 20A servo drive
[20:36:25] <ssi> if I use the '33, though, it's analog out
[20:36:34] <ssi> so I figure I'd be better off with an analog input drive
[20:39:53] <jdhnc> http://pico-systems.com/pwmservo.html
[20:41:04] <skunkworks> it is pwm in though..
[20:41:13] <jdhnc> I'm planning on using 483oz x/y and some bigger 34 for Z
[20:41:37] <skunkworks> you can get analog amc drives off of ebay pretty cheap usually

[20:43:29] <skunkworks> we have had good luck with them.
[20:44:46] <ssi> unfortunately there's not more than one of any given drive on ebay :P
[20:44:56] <skunkworks> we are running 40A ones on the K&T
[20:45:23] <skunkworks> heh - I thought you where only looking for one...
[20:45:51] <ssi> just trying to make plans for how I want to run the g0704
[20:45:58] <ssi> I always figured that you could just sorta buy the stuff
[20:46:02] <ssi> but apparently not :)
[20:46:48] <ssi> I can get little 23 or 34 frame servo motors from keling, but the only low-cost amps that seem to be available are either something like a gecko that's step/dir drive (I guess you call that position mode?) or the pico pwm-input amps
[20:47:03] <ssi> I'd think that something like a gecko 320 but without the step/dir drive and encoder feedback would actually be CHEAPER
[20:47:15] <skunkworks> there are some amps that take step/dir or analog..
[20:47:19] <ssi> stuff like those amc amps retail price is insanely high
[20:47:25] <skunkworks> yes
[20:47:42] <djdelorie> define "insanely high"
[20:48:15] <ssi> $1k
[20:48:21] <DJ9DJ> more than 3 ;)
[20:48:24] <asdfasd> it is not such a problem to build one
[20:48:29] <djdelorie> just to run a brushless motor at a random speed?
[20:48:34] <cradek> the only place you find cheap servo amps is attached to very large pieces of cast iron
[20:48:37] <asdfasd> it is much easy than step/dir
[20:48:38] <ssi> brushed motor more like
[20:48:54] <ssi> yeah there's not that much to an analog servo amp
[20:48:55] <djdelorie> even so, a brushed motor is just a brushless motor with one less wire :-)
[20:49:08] <djdelorie> (as far as the driver electronics is concerned :)
[20:49:11] <ssi> but I don't really feel like adding that project onto the stack :)
[20:49:50] <skunkworks> http://www.granitedevices.fi/index.php?q=servo-drive-vsd-e
[20:50:04] <djdelorie> if you can drive the board with something other than analog, you could just use mine :-)
[20:50:16] <skunkworks> VSD-E features industry standard pulse/direction, quadrature, PWM and analog control inputs
[20:50:30] <ssi> skunkworks: what do those drives cost?
[20:50:47] <cradek> djdelorie: an incremental software-only improvement for your amps would be to let them accept quadrature input instead of step/dir
[20:50:59] <cradek> that lets you "step" faster
[20:51:02] <djdelorie> that's two bits in a control register, the hardware already supports it
[20:51:24] <djdelorie> the limiting factor at the moment is *not* the step rate, it's the mechanicals in the machine itself
[20:51:30] <cradek> ah
[20:51:38] <djdelorie> the board will accept step pulses up to 1 MHz :-)
[20:51:50] <djdelorie> (and probably faster, but the step generator stopped there)
[20:51:52] <cradek> I mean you can generate them faster with software stepping
[20:52:00] <djdelorie> I understood
[20:52:02] <cradek> ok
[20:52:20] <cradek> no finicky setup/hold timings either
[20:52:22] <djdelorie> the hardware has step/dir, fwdstep/revstep, and quadrature built in
[20:52:27] <JT-Shop> the 7i29 does 22.5A at 165V
[20:52:50] <DJ9DJ> gn8
[20:52:55] <djdelorie> I have three more ADC inputs left on the RX62T chip too, I could break one of those out to a connector.
[20:52:59] <JT-Shop> I assume that is for a DC servo motor
[20:53:32] -!- DJ9DJ has quit [Quit: bye]
[20:53:51] <JT-Shop> ssi what size amp are you looking for?
[20:53:53] <djdelorie> Mine will do 15A at 450V
[20:54:12] <JT-Shop> did you make them?
[20:54:12] -!- ve7it has quit [Ping timeout: 245 seconds]
[20:54:16] <djdelorie> yes
[20:54:20] <JT-Shop> nice
[20:54:30] <djdelorie> http://www.delorie.com/electronics/bldc/
[20:54:52] <djdelorie> I didn't think to put analog control inputs on, though. Maybe if I respin it I'll add those
[20:55:04] <djdelorie> -10 to +10 is standard?
[20:55:08] <skunkworks> I like analog.
[20:55:12] <skunkworks> djdelorie: yes
[20:55:21] <JT-Shop> yea
[20:55:38] <djdelorie> digital output would still be faster than the motor control loop ;-)
[20:56:28] <djdelorie> hmmm... in sergvo drive, the PC wants the encoder signals, yes?
[20:56:34] <djdelorie> servo drive, not sergio drive :-)
[20:56:39] <JT-Shop> yea
[20:56:41] <cradek> yes
[20:56:58] <skunkworks> well.. with linuxcnc (and most controls) - you are limited to the trajectory/motion of 1khz to 10khz anyway...
[20:57:15] <djdelorie> if the controller board *also* wants them, it would have to include a "copy out" connector for it, if the controller also wants the encoder signals
[20:57:48] <cradek> yes it's pretty normal for the amp to give you encoder outputs to use for the position loop
[20:58:03] <djdelorie> does the pc normally want the usual ttl/cmos, or some EMI-resistant differential pair?
[20:58:23] <cradek> good encoder input boards like mesa and pico take differential in
[20:58:27] <djdelorie> in my case, the motor's hall and encoder signals are on the same connector, and you'd want to use the encoder for vector drive anyway, smoother operation
[20:58:29] -!- jstenback has quit [Quit: ZNC - http://znc.in]
[20:58:50] <djdelorie> next question: do I *really* want to make this more complicated than it already is? ;-)
[20:58:58] <skunkworks> heh
[20:59:01] <asdfasd> what I noticed is that PID controller need few pulses error on the encoder to make control, so the actual accuracy is a bit lower
[20:59:18] <skunkworks> asdfasd: compared to?
[20:59:19] <djdelorie> I think the 62T has PWM input on the step/dir pins too, I'll have to check
[20:59:51] <djdelorie> skunkworks: one thing the encoder signal is used for is a more accurate RPM reading
[20:59:53] <asdfasd> compared to the encoder accuracy
[21:00:25] <cradek> the mesa does a good sub-period velocity reading too, now
[21:00:40] <cradek> by timestamping the encoder edges

[21:01:09] <JT-Shop> http://linuxcnc.org/index.php/english/component/kunena/?func=view&catid=38&id=19055#19055
[21:02:23] <cradek> not really. you'd have to run two linuxcncs on two computers, and coordinate them somehow (hook some IOs together and use M codes for sync?)
[21:02:44] <cradek> but my understanding is this is what commercial controls did too - just use two of them
[21:06:22] <ssi> JT-Shop: honestly not sure... something that'd drive a servo that'll run that little mill
[21:06:24] <asdfasd> ssi asked for something cheap :)
[21:06:46] <ssi> JT-Shop: the keling 23 frame servos are listed as 36VDC, 4A cont, 19A peak
[21:06:52] <ssi> and 230oz peak torque
[21:07:08] -!- mazafaka has quit [Ping timeout: 240 seconds]
[21:07:09] <ssi> 350oz version is 60VDC, 4/20A
[21:07:09] <asdfasd> then better go to step/dir servo
[21:07:12] <asdfasd> is not so bad
[21:09:53] <asdfasd> most of the motors are 3000 rpm - 50 rev per second, 1000 counts encoder give you 4000 pulses or total 200khz at maximum speed
[21:10:27] <asdfasd> perfect tuned PID can control with 5 counts error
[21:10:30] <alex4nder> hey
[21:10:42] <asdfasd> ops 5 pulses
[21:11:20] <asdfasd> that mean actual frequency with guaranteed acuracy will be 40 khz
[21:12:50] <Tecan> arc radius too small... gaaaa
[21:14:03] <JT-Shop> ssi, the Mesa one does 22.5A and 165V it says H bridge so I assume that is for a brushed DC servo motor
[21:14:07] <Tecan> im going to loose my pickles
[21:14:26] <JT-Shop> ssi, do you need the motors too?
[21:14:52] <JT-Shop> cradek, thanks for the comment

[21:20:21] <ssi> JT-Shop: if you have a suggestion on a good combination, I'm definitely interested :)
[21:20:29] <ssi> I can always punt and go stepper instead
[21:20:51] <ssi> but I would really prefer to do servos controlled via that '33
[21:21:23] <asdfasd> skunkworks: no questions, much better, but some time not needed that much
[21:21:31] <skunkworks> if it where me - I would keep an eye on ebay and buy a few amc drives as they come up...
[21:21:47] <skunkworks> (to use the 33)
[21:23:44] <skunkworks> (or your analog drive of choice)
[21:24:10] <asdfasd> I made serial output on my controller so I can see the error in the same way
[21:26:19] <JT-Shop> rob__H, got some AC servos and drives that he used to upgrade his CHNC he should know the place

[21:27:23] <skunkworks> that is 80 max
[21:30:27] <asdfasd> why in USA all technical stuff is much cheaper...
[21:33:19] <skunkworks> That + mesa + encoders + servos makes a cheap true closed loop system.

[22:39:14] <SolarNRG> Does anyone in here know how to convert a .stl Openscad file into a .dwg autocad file?
[22:40:35] <Tom_itx> solidworks might
[22:41:02] <SolarNRG> I don't have solidworks, if I upload you my file, would you be willing to convert it for me?
[22:41:48] <rob__H> ud have to get it into a DXF other wise be a soldworks DWG and ud still be stuck
[22:42:44] <SolarNRG> I tried uploading my stl file to a company and they can't open it they want me to send it to them as a dwg
[22:43:32] <Tom_itx> rob__H you might be able to save it as a dwg
[22:43:34] <Tom_itx> ?
[22:43:45] <Tom_itx> mmm
[22:43:58] <SolarNRG> Is there a pastebin of files?
[22:43:58] <Tom_itx> what about iges or dxf export?
[22:44:17] <rob__H> is it a 3d part?
[22:44:20] <SolarNRG> The openscad export won't let me export my model as a dxf because it is not a 2d part
[22:44:23] <SolarNRG> Yes it is a 3d part
[22:44:31] <Tom_itx> if it's 3d you may be out of luck
[22:44:45] <rob__H> stls are quite universal
[22:44:48] <rob__H> and iges
[22:44:54] <rob__H> open them all the time
[22:45:13] <rob__H> just a pain in but when you have to repatch surfaces becasue the other system could not save in stl properly etc
[22:45:30] <Tom_itx> yep we ran into that all the time with catia
[22:45:37] <SolarNRG> Am I correct in saying the Industry ONLY accepts autocad files and if you're not rich enough to be able to BUY autocad, you can't design and order custom parts with open source files, they won't open them and there's no way of cracking autocad so you MUST pay thousands in order to even get a 3d model from one PC to another these days?
[22:45:58] <Tom_itx> no
[22:46:08] <Tom_itx> iges is quite common
[22:46:53] <djdelorie> STEP is talked about a lot, but mostly in the "everyone else supports it, we should too" way
[22:47:03] <Tom_itx> ask them what formats they support
[22:47:16] <SolarNRG> This company supports DWG only
[22:47:19] <rob__H> think depends on what kinda programs tho people you are talking to have.. i find there is quite afew out there still that dont have all the latest stuff
[22:47:24] <Tom_itx> find a new company
[22:47:33] <SolarNRG> Tom I like your thinking
[22:47:33] <Tom_itx> they are living in the dark ages
[22:47:39] <rob__H> too true
[22:47:47] <rob__H> the complex shapes and parts get now days, u cant afford not to have 3D
[22:48:00] <SolarNRG> How about this, if I send you a stl file, will someone please print that part for me and post it to me and I'll send them twenty quid in return?
[22:48:03] <Tom_itx> and my software is probably 10 yrs old or more
[22:48:27] <Tom_itx> wtf am i gonna do with a squid???
[22:48:29] <Tom_itx> :)
