[00:17:40] <TonnyG> Thanks Mr.Andypugh! u the best.
[00:26:52] <andypugh> I have added a paragraph on why stepper mode is silly: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?BLDC

[00:30:53] <TonnyG> :)
[00:31:04] <TonnyG> mesa is good then
[00:32:12] <skunkworks> I use mesa and love it.
[00:32:27] <JT-Shop> ditto
[00:32:50] <andypugh> Yeah, me too. Though I try to be even-handed and always mention Pico too.
[00:33:27] <andypugh> I sometimes mention Pluto, but only in the context of "Don't, no, really, don't"
[00:33:28] <skunkworks> The hmc I am retrofitting has 2 5i20's with a 7i33 and 7imumble (6 analog axis card)
[00:34:08] <skunkworks> andypugh: I learned a lot with the pluto. worked fine for me - but you get a heck of a lot more with mesa for like $10 more
[00:34:34] <TonnyG> how s pluto works?
[00:34:50] <andypugh> My impression is that if the Pluto works it is fine, but if it doesn't you might never find out why.
[00:34:55] <TonnyG> it use fpga also
[00:35:05] <skunkworks> pluto is a poorly made fpga with limited space ;)
[00:35:28] <skunkworks> andypugh: could be - I guess I only used it on my laptop/
[00:35:45] <andypugh> I think so, it plugs into the P-Port like the 7i43. Unlike the 7i43 it doesn't always manage to communicate with the P-port or act on all the commands sent.

[00:36:35] <TonnyG> i see.
[00:36:38] <TonnyG> :)
[00:36:57] <andypugh> As far as bang for the buck goes the 7i43 is brilliant, and probably all that any normal CNC machine needs

[00:37:28] <skunkworks> agreed :)

[00:38:09] <andypugh> Time to try sleeping I think.
[00:38:13] <andypugh> Night all.
[00:38:14] -!- bootnecklad_ has quit [Ping timeout: 240 seconds]
[00:38:15] <bdale> I'm consistently getting an error about unexpected realtime delay on task 1 on Axis startup, then things seem fine, on a machine that shows worst-case jitter numbers of under 13k on a long run of the latency test. should I be worried about this?
[00:38:27] <TonnyG> Thanks again mr.Andypugh!

[00:39:02] <TonnyG> night!
[00:40:26] <Valen> bdale: I sometimes get that as a result of starting the openGL window
[00:40:44] <Valen> bdale: try running latency test, then starting glxgears
[00:41:28] <bdale> Valen: I've tried that, numbers are still in the 13-14k range
[00:41:43] <Valen> is there a spike when you *start* gears?
[00:41:47] -!- Dallur has quit [Client Quit]
[00:42:16] <bdale> what do you mean by spike? increase of a few hundred ns, maybe
[00:42:36] -!- mhaberler has quit [Quit: ChatZilla 0.9.86 [Firefox 3.6.13/20101203074432]]
[00:42:39] <Valen> i see a spike of ~30k when opening an opengl window
[00:42:48] <bdale> no, I don't see that
[00:44:53] <bdale> I've got another machine that latency tests slightly worse (in the 20k range), just trying to cover the bases before I swap to that one and see how it performs .. this is an IH 3-axis mill I've set up using pluto-servo, fwiw
[00:46:36] <bdale> if I click through the error, all seems to run fine afterwards
[00:49:33] <JT-Shop> you only get the warning once!
[00:49:45] <bdale> correct
[00:50:00] <Valen> what he means, is if it happens again, it won't tell you about it
[00:50:05] <Valen> which is sucky to my mind
[00:50:09] <bdale> yes, I understand
[00:50:12] <JT-Shop> very sucky
[00:50:26] <Valen> is there some reason for that?
[00:50:31] <bdale> just wish I understood what it meant better
[00:50:41] <Valen> other than its easier to squelch it that way
[00:51:08] <Valen> it means that the fast thread didn't happen at least once
[00:51:16] <JT-Shop> the warning means you don't get steps on time
[00:51:37] <bdale> which I care less about since I'm using a pluto card in servo mode, not sw generation of steps, but point taken
[00:51:37] <JT-Shop> so the path generated may not be correct
[00:51:56] <Valen> whatever task 1 is was meant to happen 1000 times a second (or whatever) but something happened that made it not run one of those times
[00:52:42] <bdale> ok, it just seems weird that on a machine that has latency numbers well below 20k and a base thread period of 100k, this is happening
[00:53:21] <JT-Shop> how long did you run the latency test?
[00:53:44] <JT-Shop> some problems with hardware can be minutes apart
[00:53:44] <bdale> I've run it different lengths different times .. longest was several hours with lots of random activity
[00:54:01] <bdale> current run is at least 15 minutes in
[00:54:09] <bdale> and max is 15750
[00:54:48] <bdale> I guess I should probably just try the other machine I have that I could use instead of pulling out my hair over this
[00:56:27] <JT-Shop> after you get the error did you check the dmesg?
[00:56:32] <bdale> yes
[00:57:21] <JT-Shop> and it said something to the effect the last run was so large...
[00:57:26] <bdale> yes
[00:57:38] <bdale> [ 999.663710] In recent history there were
[00:57:38] <bdale> [ 999.663712] 223614, 132924, 163387, 181233, and 178452
[00:57:38] <bdale> [ 999.663714] elapsed clocks between calls to the motion controller.
[00:57:38] <bdale> [ 999.663793] This time, there were 181163 which is so anomalously
[00:57:39] <bdale> [ 999.663795] large that it probably signifies a problem with your
[00:58:14] <JT-Shop> yea, something is hogging the cpu
[00:58:17] <bdale> which just seems weird, since the 'this time' number is median of the others
[00:58:31] <JT-Shop> screen saver is disabled
[00:58:42] <JT-Shop> ?
[00:58:48] <bdale> hrm, not sure about that .. checking
[00:59:14] <JT-Shop> I had one machine that the screen saver just before it kicked in hogged the cpu or something
[00:59:22] <bdale> enabled but not active, just disabled it
[01:01:10] <bdale> maybe I'll swap out the video card and see if that helps before I swap the entire machine (which would mean moving the hard drive, etc) .. bbiab
[01:01:24] <JT-Shop> yep good things to try

[01:16:17] <Valen> soaking CPU shouldn't cause it an issue
[01:16:22] <Valen> thats the point of rtai
[01:16:42] <Valen> "really should work" is the dual core atom boards
[01:19:57] <skunkworks> bdale: 100k base thread?
[01:20:14] <skunkworks> do you need a base thread? with the pluto I would think you would only need the servo thread.
[01:26:55] <skunkworks> also are you trying to run the thread the pluto is in at 100k? that might be way to fast.

[01:50:16] <skunkworks> that is probably your problem. the pluto driver might not be able to run at 100k - that is .1ms - 1ms should work though (1000k)

[02:18:59] <mole|2> Hi, trying to restore an emc machine from backups
[02:20:26] <mole|2> and getting threads error. Google shows this has been discussed here a while ago... HAL_LIB error: new thread period 50000000 is less than existing thread period
[02:21:33] <mole|2> and the advice was to change the thread period so the threads are craeted from fastest to slowest
[02:22:26] <mole|2> anyone know how I can do that? Make the servo thread really slow? Runs through a modified 5i20

[15:11:26] -!- micges [micges!~micges@env152.neoplus.adsl.tpnet.pl] has joined #emc
[15:11:46] <awallin> we upgraded ours over many years bit by bit, so maybe the overall cost doesn't seem so bad
[15:11:58] <atmega> mainly delrin, alum, brass, maybe some stainless
[15:12:18] <awallin> but if you would do all the upgrades right away its probably best to invest in something that is more suited for cnc from the beginning
[15:12:42] <awallin> I think the dovetail ways might work for cnc better on a big machine where the table is very heavy
[15:13:04] <atmega> whatever I get will pobably just be steppers on existing lead screws first
[15:13:29] <awallin> so basically: linear rails + ballscrews + new spindle = a lot of upgrading...
[15:14:28] <atmega> those rails don't look too sturdy? are they ok with side loads?
[15:15:08] <awallin> I think the rails on our machine are 15mm (IKO brand).
[15:15:48] <awallin> if you have <2kW on the spindle the cutter forces will never be that high... the column deflects more than rails/small-ballscrews etc
[15:16:33] <atmega> any opinion on that vs. an X3 for conversion?
[15:17:44] <awallin> something like this would be nice for an emc2 project: http://img.alibaba.com/photo/219009190/small_micro_CNC_DIY_milling_XH400_frame.jpg
[15:17:55] <awallin> but that frame alone is 5-6k + taxes and shipping
[15:18:33] <awallin> I haven't seen an x3 in real life... looks similar to bf20
[15:18:33] <nullie> we have cheaper micro cnc available
[15:19:18] <awallin> the stock bf20 has an mk2 spindle I think. not the fastest to change manually. some R8 or other quick change would be nice on a machine without atc
[15:24:41] <atmega> the grizzly version has R8
[15:25:46] <atmega> http://grizzly.com/products/G0704
[15:26:17] <atmega> but, it seems awfully light to be that big
[15:27:46] <awallin> it looks like the bf20 version with the longer table
[15:29:14] <awallin> here's about the most hard-core thing our mill does: http://www.youtube.com/watch?v=e5h1-K_lt6k
[15:29:44] <awallin> the grim truth is that you want linear rails, ballscrews, a 2kW or more spindle, and servos with encoder feedback to do that
[15:30:51] <awallin> sure you can try with dovetails, the stock spindle, and steppers... but our experience is that it will only result in headache... :)
[15:33:31] <atmega> that will be true with any machine though?
[15:35:56] <awallin> pretty much. with a full-size bridgeport style manual machine I think you would not have to replace the dovetail ways. only install ballscrews instead of the screws for manual operation
[15:36:44] <atmega> no room for one of those
[15:36:58] <awallin> If I would have the cash and especially the space I would consider a chinese mini-vmc frame, or maybe a lightly used second hand vmc with broken control.
[15:39:34] <awallin> atmega: would you have space for this: http://www.optimum-maschinen.de/produkte/fraesmaschinen/wf20vario/index.html
[15:40:21] <atmega> probably, but, it looks way more expensive than the grizzly

[15:44:00] <atmega> that grizzly bf20 and their X3 are the same price. The X3 has less travel and the stated spindle motor specs are lower
[15:44:21] <atmega> but the shipping weight is 50% more
[15:52:44] <dimas__> awallin, what is the smallest spindle system suitable for ATC? for desktop size milling machine
[15:53:44] <awallin> iso30 is what the mini vmc's use I think
[15:53:45] -!- SWPLinux has quit [Read error: Connection reset by peer]
[15:54:00] <dimas__> thanks
[15:54:22] <awallin> the haas officemill might use iso20, but I haven't seen a lot of tooling for that in the catalogs..
[15:54:27] <cradek> you can put a tool changer on anything - machines that drill circuit boards can use 1/8 tools with depth rings in a collet
[15:54:34] <awallin> might be different where you are
[15:55:31] <awallin> the spindle is probably a large part of the cost of a vmc
[15:55:43] <dimas__> cradek, can you give an example link?
[15:56:18] <cradek> not really
[15:56:28] <cradek> I mean, I could search, but I didn't
[15:56:57] <cradek> I just meant that there is probably no minimum size for a spindle that changes tools automatically

[17:42:45] <skunkworks> bdale: great!
[17:44:03] <skullworks> On a non-EMC related topic - Can anyone tell me or point me to where I can find out the limits of the file system for a "fakeRaid" raid5 on 10.04?
[17:45:43] <skunkworks> you probaby need to make another thread that is runnning 160k (160000ns) with your charge pump in (if I did that right)
[17:45:55] <skullworks> I would love to setup a 4x 2TB array using 3 active with 1 spare in Raid 5 but I'm not sure if the 32bit version can cope.
[17:46:35] <bdale> yes, I've been working on that, but I'm seeing a weirdness where even when I put the charge pump function on the faster thread, it seems to output a square wave at the freq I'd expect if it were on the slower thread ... debugging that now
[17:49:50] <skunkworks> bdale: you need it in a thread that runs 2x the charge pump frequency
[17:50:07] * bdale gets distracted for a while by the unexpected early arrival of a huge box containing the new production run of TeleMetrum boards .. http://altusmetrum.org
[17:50:26] -!- isssy [isssy!~isssy@78-83-51-185.spectrumnet.bg] has joined #emc
[17:50:44] <bdale> skunkworks: right, I understand that .. trying to set a base thread period of 100000 and a servo thread period of 500000 just isn't doing what I expect ... will get back to it in a bit, once I take a look at my new toys. ;-)
[17:51:20] <bdale> I'm getting a 1khz output, which is consistent with the charge pump actually being on the servo thread when I *think* I'm putting it on the base thread
[17:51:33] <bdale> should be 5khz ...
[17:52:12] <awallin> the periods are in nanoseconds
[17:53:07] <awallin> if you want a 5 kHz square wave out your baser-period needs to be 1/(10 khz) seconds
[17:53:33] <awallin> thats 100 microseconds, or 100 000 nanoseconds
[17:53:35] <awallin> I think...
[17:53:53] <skunkworks> sounds right

[18:00:32] <bdale> right, I figured since I was running 100000 before and the charge pump worked, I'd just put the base thread back to that, which keeps the servo thread a nice integer multiple of the base thread
[18:01:02] <bdale> the spec on the charge pump board is that it needs at least 3khz, feeding it 5khz for now should be fine
[18:01:25] <awallin> what HAL do you have for the charge-pump output?
[18:01:36] -!- bootnecklad_ [bootnecklad_!~bootneckl@89.241.37.117] has joined #emc

[18:01:52] <bdale> setp charge-pump.enable 1
[18:02:13] <bdale> oh
[18:02:14] <bdale> I get it
[18:02:29] <bdale> even if the charge pump output is changing faster, the pluto isn't
[18:02:39] <bdale> so I'm rate limited to the pluto output update rate
[18:02:56] <awallin> the fpga should be clocked at MHz ?
[18:03:08] <bdale> yeah, but the pluto write task is on the servo thread
[18:03:29] <awallin> ok
[18:03:37] <bdale> hrm
[18:03:50] -!- bootnecklad has quit [Ping timeout: 240 seconds]
[18:04:32] <bdale> so, ideally, I'd like to clock the pluto write faster .. either that, or I need to find another output to drive the charge pump .. or I need to hack the charge pump's firmware to accept a lower clock rate
[18:04:44] <bdale> frankly, hacking the charge pump to accept 1khz seems like the *best* answer
[18:04:56] <bdale> there's no earthly reason it needs to be clocked so fast
[18:06:19] <skullworks> add a second lpt port for charge pump and any extra I/O you don't want to run through the Pluto?
[18:06:41] <bdale> I could, but everything I need maps into the pluto just fine
[18:07:07] <bdale> and the way I've built up the NEMA box full of electronics, having to run another cable from the PC would be annoying. clearly not impossible, just annoying.
[18:09:04] <skullworks> just wondering - did you but the pluto on the back of the PC and run cables, or a cable to the box with the pluto in it?
[18:10:35] <bdale> 25-pin cable to the box, with the pluto mounted on a custom breakout board inside the box .. works great
[18:10:44] -!- isssy has quit [Quit: Visitor from www.linuxcnc.org]
[18:11:39] <bdale> box is mounted on the wall next to the mill, PC chassis sits on top of the box
[18:12:08] <skullworks> yeah that is the pluto's big fault - it needed a good daughter board, breakout board.
[18:12:14] <bdale> someday I'll get some pix up on my web site .. too much other stuff going on to take time right now
[18:12:46] <bdale> actually, I think it'd be easy to build a pluto compatible board that does all this stuff right .. if there'd be sufficient interest, I may do that at some point

[18:14:11] <bdale> just sent Arturo an email asking if there's a 1khz version of the firmware for the micro on the C4 board, or if not whether I can have the source to hack it myself
[18:15:11] <bdale> since it's using a micro to count pulses and not an analog filter, it should be a simple firmware mod

[18:22:19] <skullworks> come soo far yet... using a micro means you can't really have user selectable jumper settings like you could with a regular capacitor circuit.
[18:27:09] <SWPLinux> bdale: if you're not using all the stepgens/PWMgens on the pluto, you could hook one of those output to the charge pump
[18:27:37] <SWPLinux> the pluto has a watchdog, so it will stop sending the steps/PWM if emc crashes or shuts down

[18:30:42] <bdale> SWPLinux: currently I'm only using 3 of the pwm channels, but I intend to use the fourth eventually. so it could be a good short term hack, but not a good long term solution. the CNC4PC C4 board I picked up uses the Microchip 12F629 .. if for some reason Arturo doesn't want to share and/or doesn't have an alternate firmware image, that's well within my ability to just write replacement firmware for. hope I don't have to, though.

[19:11:00] <bdale> it was hugely tempting to tweak a bunch of things and do my own board design, and I may do that eventually, but I finally decided just building up some boards using your existing design would get the mill online faster. been trying to stay 100% open source / open hardware on this build, it's really pretty funny that the one thing I bought with a preprogrammed microcontroller on it is now the thing that's keeping me from bringing the machine fully online. /o\

[19:23:57] <skullworks> I'm going to swapping out the OEM spindle motor for a nice new Baldor 3600rpm 2hp unit.

[19:28:52] <Bridgeport2> what i need is for the laptop to be used to create ,edit and test run programs for my bridgeport II mill running emc2 2.4.6

[19:31:14] <Bridgeport2> i started emc2 from the drop down menu and ran sim axis
[19:31:22] <psha> netherless for testing emc2-sim is enought
[19:32:00] <psha> emc2-sim is non-realtime version of emc2 - wokring in userspace for testing/development
[19:33:09] <Bridgeport2> what do I try next
[19:33:59] <psha> edit /etc/apt/sources.list, replace emc2.4 with emc2.4-sim in deb http://www.linuxcnc.org.... line
[19:34:06] <psha> then apt-get update; apt-get install emc2-sim
[19:34:23] <skunkworks> I thought the 'waiting for s.axes' was because of the MNL line in the ini file
[19:34:49] <Bridgeport2> the computor is a gateway amd turion 64 x2 with like 3 or 4 gig of ram
[19:37:36] <Bridgeport2> psha I understand the basics of what you just asked me to do but am novice and need to have you walk me through this in plain english
[19:37:45] <skunkworks> the NML=emc.nml line - but I thought those where all removed.

[19:39:18] <psha> emc2-sim is available from another repository then emc2 (rtai)
[19:39:26] <Bridgeport2> why wont the sim options on live cd work they have alwaways worked for me before

[22:14:09] <Connor> any one have any good suggestions ?
[22:14:53] <andypugh> For what purpose?
[22:15:23] <Connor> make sure my router is parallel to the deck
[22:15:45] <andypugh> I think that a bit of bent 1/4" bar would be good start.

[22:17:03] <andypugh> It doesn't have to be very stiff, so just bend a bit of rod, hold one end in the collet and mount the DTI on the horizontal remainder of the bar.
