[00:16:17] <pcw_home> TH9000: probably 7I77 for analog servos (5 axis plus spindle)
[00:19:12] <andypugh> My CNC has been annoying me all day. It seems to run reliably, as long as i don't do anything with the PC. But, for example, opening a URL will cause the PC to restart. Or opening a file. But it _only_ seems to happen if I do something with the OS.
[00:19:27] <andypugh> I suspect that my 12V supply might be weak.
[00:20:06] <pcw_home> atom MB with 12V power?
[00:20:07] <Tom_itx> you drawing the 12v from the pc?
[00:20:16] <Tom_itx> picopsu?
[00:20:46] <andypugh> PicPSU
[00:21:20] <andypugh> 2kW 24V PSU, then a 12V DC-DC converter
[00:21:24] <Tom_itx> they make several, maybe you need a bigger one
[00:21:50] <andypugh> It's an 80W PicoPSU, but the 12V converter is only really 2A.
[00:22:27] <pcw_home> That might be bit marginal
[00:22:43] <andypugh> I have a bigger one on the way
[00:22:57] <Tom_itx> do you have more than one?
[00:23:05] <Tom_itx> maybe you can share the load in the interum
[00:23:40] <pcw_home> It would be nice if they would take 19V in so you could us a laptop PS
[00:24:11] <Tom_itx> they might
[00:24:59] <kwallace1> What would be cool is a PC power supply that used 220 VAC for input.

[00:38:04] <kwallace1> For a new install, I would tend to use PWM servos/ amps over +/- 10 analog. Am I wrong?
[00:39:34] <andypugh> I don't think it matters much, so would choose on other criteria.
[00:40:49] <kwallace1> But PWM amps are cheaper, unless the machine already has +/-10 amps.
[00:41:40] <kwallace1> There is an external feedback loop with +/-10.

[04:39:20] <zultron> FreezingCold, I'm interested in a refactor/fork of pycam in python, C/C++ TPGs, qt GUI, and VTK 3D.
[04:40:17] <FreezingCold> zultron: What's VTK for?
[04:40:25] <zultron> 3D rendering.
[04:40:46] <zultron> Check out awallin's site:
http://www.anderswallin.net/tag/cam/
[04:41:00] <FreezingCold> But why not OpenGL?
[04:41:23] <zultron> Too low level.
[04:41:39] <FreezingCold> I haven't worked with it much, but OpenCL might be a possible candidate for some of the number crunching (regardless of VTK vs OpenGL)
[04:41:53] <zultron> But pycam uses OpenGL right now, so if you want to stick to that, it would be a no-brainer. :)
[04:42:52] <FreezingCold> zultron: It doesn't use any GPU processing (aside from the final rendering), right?
[04:43:17] <zultron> VTK has a bunch of nice features for interaction. For example, it would be pretty easy to select one or more faces on your model to restrict your surfacing operation to. ;)
[04:43:45] <FreezingCold> interesting
[04:44:33] <zultron> I don't know that much about it. I was looking at it almost a year ago when I was thinking about getting serious with PyCAM, but it never happened, other than that settings persistence patch.
[04:45:15] <FreezingCold> What I'd like the development model to be is a backend written in pure C (which extends possible uses OpenCL if I see a preference benefit) that is meant to be command line driver, and then a qt GUI laid over top that can be maintained separately
[04:45:31] -!- TH9000 has quit [Quit: leaving]

[04:48:47] <zultron> I like hacking LinuxCNC RTAPI in C. I like writing GUIs in python. Application backends, I'm more flexible about, but C seems like a lot of work for something as complex and something needing to be as flexible as a CAM application.
[04:49:45] <FreezingCold> On a similar note, why do you prefer python over qt or gtk?
[04:52:41] <zultron> ??? I don't get it. Python is a programming language, but qt and gtk are GUI libs.
[04:53:16] <zultron> FreeCAD is written in python and C++ and uses qt.
[04:53:28] <zultron> PyCAM is written in python and uses gtk.
[04:53:57] <FreezingCold> I mean you said 'writing in GUIs in python'
[04:55:01] <zultron> Ha, you got me. Rephrase: I like writing GUI layers in python. I doubt I'd prefer qt over gtk.
[04:56:03] <FreezingCold> for a second I thought you were writing something completely in python lol
[04:56:30] <FreezingCold> qt impressed me when BlackBerry switched to it
[04:56:41] <FreezingCold> sadly they failed badly at it because they closed up the source so bad
[04:57:12] <zultron> Here's what I said first:
[04:57:14] <zultron> <zultron> FreezingCold, I'm interested in a refactor/fork of pycam in python, C/C++ TPGs, qt GUI, and VTK 3D.
[04:59:22] <zultron> Anyway, I don't see that VTK makes use of OpenCL anywhere, and have yet to check whether VTK can take better advantage of GPUs than just for rendering.
[05:02:26] -!- joe9 has quit [Remote host closed the connection]
[05:02:39] <FreezingCold> OpenCL is similar to CUDA. It'd be for the task/tool path generation
[05:03:05] <FreezingCold> but I'd have to actually be assed to look at the source code more to see if it could use lots of parallel instructions or not
[05:04:06] <FreezingCold> regardless of how much or little work is done, I'm pretty sure pycam has to be forked seeing how it hasn't been updated in months as far I can tell
[05:04:53] <FreezingCold> last update was 8 months ago
[05:05:10] -!- toner has quit [Ping timeout: 246 seconds]
[05:06:08] <zultron> Yeah, I've looked at OpenCL, neat stuff. I'd start by grabbing existing tpgs and working them in, and let folks like you write better ones later on. ;)
[05:06:59] <zultron> Pycam doesn't necessarily need a fork. Lars seems pretty willing to give up the reins and let someone else step in.

[06:25:13] <MacGalempsy> my servo amplifier has a tach +/- and it has one going to negative and the other goes to a ground signal, or + terminal on the motor. do I plug the + into the controllerboard and set it as a tach?
[06:35:54] <kwallace> My guess is that the the tach on the motor should go only to the tach input in the amp. LinuxCNC will provide a velocity command, the amp will try to make the tach match the command.
[06:37:04] <MacGalempsy> ok, that sounds good to me
[06:37:40] <MacGalempsy> thanks
[06:38:02] <MacGalempsy> also, is it better to power endstops with the controller board, or external 5v?
[06:39:21] <kwallace> The amp velocity gain will need to be tuned to match your motor and tach characteristics before doing the LinuxCNC velocity loop tuning. Usually there is an amp tuning procedure in the the amp manual.
[06:40:05] <MacGalempsy> the amps should be pre tuned
[06:40:21] <MacGalempsy> because the machine was previously set up and running
[06:46:18] <MacGalempsy> just making sure to plug the amps back to the original motors
[06:52:05] <RyanS> If I wanted to add a VFD to a drill press, is it pretty much a no-brainer to hook it up to a three phase drill press? ie no need to change the motor
[06:52:30] <kwallace> The polarity of the tach and amp input need to match. If they don't match the amp will think that that the motor is going slower when you increase the command, which will tell the amp to go faster until it hits a limit.
[06:54:46] <FreezingCold> I haven't used LinuxCNC, but what exactly is the reason of "selling" it as a distro instead of just Debian/Ubuntu packages?
[06:54:58] <kwallace> RyanS: That sounds good too me, but I haven't seen any three phase drill presses before.
[06:57:37] <RyanS> They seem to be sold as 'industrial', I was thinking of a good secondhand three-phase. Although I don't know if it's possible to abuse a drill press the same as used milling machine
[07:00:37] <RyanS> I guess you could stuff up the bearings

[08:20:10] <archivist> the brave will unwrap the winding end connections and modify, the timid buy the expensive 240 single phase in 440 3 phase out inverter (costs a lot more)

[09:01:38] <RyanS> 1.5kw/2hp is actually a pretty serious drill press right?
[09:04:15] <RyanS> Granted thatis a Chinese VFD
[09:06:31] <Loetmichel> RyanS: it is
[09:06:43] <Loetmichel> the cheap chinese ones have 350 to 500W
[09:08:01] <Loetmichel> but you have to have a fitting motor with 3 phase ac
[09:08:27] <Loetmichel> normally there are cheap single phase motors with starter cap on these cheap chinese drill presses

[10:46:48] <RyanS> Possibly , but 3ph, 415v can be easily converted for variable speed
[10:48:31] <archivist> but if making small stuff the concentricity of chucks is often not as good
[10:49:31] <archivist> they even cannot hold very small drills, so you would need a small chuck and some morse adapters
[10:50:37] <RyanS> am I to understand that with belt drive, let's say you want to step drill *properly* you need to change belts 'thrice'? Normally I just use the target speed for the final drill
[10:51:54] <RyanS> With VFD you can even tap because you can reverse. I think
[10:52:52] -!- fomox [fomox!~chatzilla@77-110-193-140.inet.signal.no] has joined #linuxcnc
[10:53:00] <archivist> often one uses a tapping head on a drill, it has the reverse internally geared
[10:53:56] <archivist> while a vfd can reverse its reaction is not really quick enough for tapping
[10:54:42] <archivist> you will need to add braking resistors and adjust the vfd for maximum braking
[10:58:29] <RyanS> I just need more z travel than the current bench drill really and not to piss around with belts
[10:59:20] <archivist> having more than one drill for different jobs can be useful too
[11:01:05] <archivist> I have a high speed drill for small holes, and a bench for middle sized work, currently lack a working floor drill for big work
[11:01:59] <MacGalempsy> when ready to test pins, do I need to have a hal file setup, or can I just test pins in halmeter directly?

[11:17:36] <RyanS> I guess in mass production, they don't tend to have dedicated drilling machines these days because the task gets done in a machining centre
[11:19:10] <archivist> yup, they are often just a general workshop tool these days, with a drop in quality which goes with that
[11:21:32] <Loetmichel> who has time to center-punch, predrill and countersink in production these days anyway?

[12:07:37] <MacGalempsy> any tips

[12:11:54] <jthornton> scroll down to the bottom figures

[12:14:17] <MacGalempsy> ok. I figured out the relay coil part. but it was a 50/50 on the ins
[12:14:45] <MacGalempsy> should be easy enough, I got one more 5v phone charger to hack up
[12:15:41] <MacGalempsy> they what is the purpose of being able to put in 24v dc to fieldpower?

[12:21:40] <MacGalempsy> would really like to get the axes moving this week
[12:22:57] <jthornton> I usually test the estop, the limit switches then start with the axes
[12:24:03] <MacGalempsy> sounds like a good method. i'll leave you guys alone and get to bed. Thanks for the help, and i'm sure there will be a few more questions tomorrow.
[12:24:20] <jthornton> manually move an axis to the middle and energize one axis then test it

[12:25:30] <RyanS> I don't get people dicking around with a bunch of clamps on a drill press, just use a compound table and vice and be done with it

[14:59:34] <pzpz> JT_Shop: what do you mean?
[15:00:47] <Loetmichel> Jymmm: too expensive
[15:00:59] <Loetmichel> i would suggest a simple square wave oscillator with a 10khz or 100khz signal and then some filters to straighten the overtones (level)... should work
[15:01:03] <Jymmm> Loetmichel: $4 is too expensive?! you cheap bastrd!
[15:01:12] <Loetmichel> but i havnt seen something like that in a lionmg time, especially not with antennae and groundplane
[15:01:27] <Loetmichel> and dds up to 1ghz is a bit tricky
[15:01:41] <kwallace> I have used mist because my coolant system isn't hooked up. There is much less coolant flow so it drains into a can. The down side is that the mist fills the air and gets on everything including lungs.

[15:13:27] <kwallace> In my opinion, the machine needs to be made from the start to tolerate water based coolant. My mill was a filthy rusty mess when I got it, so it will never see water again, as long as I can say so.

[15:19:15] <CaptHindsight> why not reclaim the ethanol? Condense the vapor and collect it back coolant tank. You don't want to breath the vapors anyway.
[15:20:03] <Loetmichel> CaptHindsight: or to smoke nearby
[15:20:06] <Loetmichel> :-)

[21:14:59] <WalterN> why are so many people in that thread saying that if programs are edited, said person that edits gets fired?

[21:16:31] <cradek> a lot of people are the smartest person they know? not sure how to say it.
[21:17:08] <toastyde1th> WalterN, because there's a massive, massive difference between how you have to treat untested vs tested code
[21:17:42] <WalterN> tweaking a program to me is the same as tested program
[21:18:07] <toastyde1th> re-read the types of changes they're objecting to
[21:18:18] <toastyde1th> and yes, on big machines, a tweak can take a program that runs fine to crashed
[21:18:41] <toastyde1th> some of the bigger tools i've used are very sensitive to load and chatter
[21:18:52] <WalterN> making a loop thing... no big deal
[21:19:26] <toastyde1th> in a small shop with cheap parts and small machines, sure
[21:19:50] <toastyde1th> confidence isn't worth much if you stand to scrap a bigger part, which a lot of the guys on practicalmachinist are concerned with

[22:19:54] <rob_h> N1000 can = any number btw just never needs to be used some where else ur it will jump there or somethign worse

[23:04:02] <somenewguy> I have ideas obviously, but usually people do it a certain way cause it has been proben to be a lot better than whatever you make up beofre ever actually using the tool lol
[23:04:05] <pcw_home> there are a few PIN_xxx files with SPI
[23:04:14] <Tom_itx> somenewguy, i don't have a rotary.. just the 3 axis cnc
[23:04:20] <somenewguy> oh I misunderstod
[23:04:31] <Tom_itx> wish i did
[23:04:35] <somenewguy> I have a taig, came w/ the rotatary
[23:04:41] <mpictor> yea, but is there anything in particular I need to do to ensure that the spi pins don't overlap with something else?
[23:04:46] <pcw_home> you can grep for them (the pin file with 7I65 in the name use BSPI)
[23:04:50] <kwallace> http://www.cnccookbook.com/CCRotabToys.html
[23:04:52] <mpictor> how they get their numbering is not obvious to me
[23:04:57] <somenewguy> and some parts for a 3 jaw vice that are completly wrong for the setup, which lead to quite a bit of confusion for me for a wile lol
[23:04:59] <somenewguy> while
[23:05:11] <archivist> somenewguy, google t slot nut
[23:05:11] <mpictor> this has spihttps://github.com/mpictor/7i80-hostmot2/blob/master/pin/sp/PIN_SP4_34.vhd#L76
[23:05:19] <mpictor> this has spi
https://github.com/mpictor/7i80-hostmot2/blob/master/pin/sp/PIN_SP4_34.vhd#L76
[23:05:35] <kwallace> somenewgut: see my link above.
[23:05:37] <Tom_itx> mpictor i had to map the sserial to certain pins so they would fit the actual IO functions of the board
[23:05:45] <kwallace> Oops.
[23:06:45] <mpictor> Tom_itx: I'm not limited by the hardware, just the fpga configuration - I have a breakout board not a smart serial device
[23:06:55] <archivist> somenewguy, not the same rotary but you can see them in use
http://www.archivist.info/cnc/stage6/P1010026.JPG
[23:07:10] <Tom_itx> pcw_home, typo on the sserial add to cart page
[23:07:26] <Tom_itx> 7i84 description is for a 7i70
[23:07:33] <pcw_home> That particular config has 4 instances of DBSPI, each with one channel but you could have 1 instance with 16 channels
[23:08:03] <mpictor> I just want one instance with one channel, along with servo and stepper instances
[23:08:15] <somenewguy> I did, I see how he mounted the 3 jaw onto it using tslots
[23:08:29] <somenewguy> I just figured there must be a "normal" way of mounting the work directly to the rotary face
[23:08:33] <pcw_home> thz tom_itx, I'll tell Lily
[23:08:43] <somenewguy> I don't have any kind of 3 or 4 jaw
[23:09:00] <archivist> somenewguy, same t slot nuts and whatever clamping the job needs
[23:09:06] <somenewguy> and I am obvously not a machinest, so just tryign to figure out if there is a normal way of doing this
[23:09:33] <somenewguy> clamping straight down is fairly obvoius, although the table is so tiny I figure most all work will enver fit on it
[23:09:41] <somenewguy> is there a way of holidng parts radially on it?
[23:09:46] <somenewguy> like how a 4 jaw would
[23:09:51] <mpictor> pcw_home: if I paste those 4 pin lines into another config and delete the 4 they replace, as well as adding to ModuleID, is that enough?
[23:10:11] <mpictor> I'm really confused as to how the pin numbers are determined by ise
[23:10:15] <archivist> somenewguy, yes mount a chuck
[23:10:39] <pcw_home> Pretty much
[23:10:57] <mpictor> ok, thanks :)
[23:11:13] <pcw_home> the pin number are determined by where the pin desc is on the physical IDrom record
[23:12:28] <pcw_home> that is the PINDesc section of the PIN_XXXX file starts at GPIO 0 and goes to the last GPIO on the card (GPIO71 on a 7I80HD for example)
[23:12:45] <mpictor> by the way, the 7i80.zip I downloaded a week or so ago was missing some files - 7i80hd.ucf, i80hd_x*card.vhd
[23:12:52] <kwallace> T-Slot clamps with side force
http://www.industrydepot.com/TSlotClamps.htm
[23:13:15] <mpictor> and I assume that there's supposed to be a TopEthernet25* to go with the TopEthernet16*
[23:13:25] <Tom_itx> kwallace, that or camlocks
[23:13:34] <mpictor> ok, that explaination of pin assignment makes sense

[23:14:13] <pcw_home> for a single channel DBSPI and BSPI are basically the same so chose BSPI since its supported

[23:16:37] <pcw_home> (16 bit CPU)
[23:16:54] <mpictor> pcw_home: and how do I set the BSPI frequency for that instance?
[23:17:09] <mpictor> oic - I thought it was fpga size
[23:17:30] <pcw_home> I have no idea how the driver works i presume its a parameter
[23:17:45] <mpictor> oh, it's configurable from the pc?

[23:19:28] <andypugh> mpictor: BSPI is supported in a slightly half-hearted way.
[23:19:47] <pcw_home> sure, Ethernet support for SPI will be even more interesting than other things
[23:20:54] <pcw_home> The SPI interfaces need some work as well to support autosend and DPLL triggered autosend
[23:21:08] <andypugh> mpictor: You basically have to write your own comp that calls functions provided by the Hostmot2 driver.

[23:21:40] <pcw_home> I'm actually using the 7I80 SPI to test the SPI Hostmot2 host interface
[23:21:40] <andypugh> There is a possibility that in the future I might make it work like SSI and BISS (which in turn copy elements of Smart Serial)

[23:22:45] <mpictor> I assume the B means buffered?
[23:23:04] <andypugh> Yes.
[23:23:54] <andypugh> If you look at the mesa_7i65 driver file, that is an example of a comp that uses BSPI. You can probably just modify that for your purposes.

[23:24:33] <mpictor> I've been wondering... what architecture is the cpu synthesized in the fpga? custom?
