Re: [Emc-users] LinuxCNC Integrator meeting Germany?
Hello Rene, is your workshop big enough for all the people that have already stated their interest? Can you tell me/us where you are located around Stuttgart ? And maybe we should move this to a wiki page ? BR Max. Hello, my name is Rene I'm also located next to Stuttgart. A meeting in Stuttgart would be very great! Me and my cousin will come for sure. We have a big working Linuxcnc machine and visiting our workshop would be no problem to us. We are currently working on something that would change Linuxcnc a lot for professional users and when I say a lot I mean really a lot ! But I will not say more at this time :) Maybe we can introduce it to you during the meeting in Stuttgart.

Re: [Emc-users] LinuxCNC Integrator meeting Germany?
Hello Everybody, I collected these emails of the eleven interested people who already stated their interest in a linuxcnc meeting. Four of those people are close to Stuttgart, two are from Austria (please correct me if I am wrong). So I think it would be sensible to meet somewhere in or around Stuttgart. So I think there are three mayor questions: 1. Location - Something big enough to bring gear, something to mess around with, maybe have one cnc machine there ? Anybody got ideas ? 2. Date - maybe not before the summer holidays start ? So maybe late September or early October 2013 - when everybody is back ? That would give people time to make travel arrangements and have a chance at a still free schedule. 3. What to do if we should meet up ;) I have a small (1,2m x 1,5m) cnc machine with linuxcnc that I could load into a van. But I'd need a forklift at the destination to unload and three phase electric power, too. -- Here are the interested people: Christian Stöveken, christian.stoeve...@gmail.com, Stuttgart, Germany Michael Haberler, mai...@mah.priv.at, Austria Martin Schöneck, c...@martinschoeneck.de, Ludwigsburg - near Stuttgart, Germany Alex Joni, alex.j...@robcon.ro, Timișoara (still?), Romania Sven Wesley, svenne.d...@gmail.com, loc. unknown Viesturs Lācis, viesturs.la...@gmail.com, loc. unknown Matt Shaver, m...@mattshaver.com, USA Alex Chiosso, achio...@gmail.com, northern Italy Jan Maier, jan.ma...@joline.net, Tuebingen - near Stuttgart, Germany W.

Re: [Emc-users] 7i43 watchdog has bitten, looking for the cause ?
Hello Everybody, many thanks for your great input. It has given me some ideas of what I can try next. As we have a holiday on Monday I will not be in the shop until Tuesday. I have a ssh connection to the machine, but since I started this thread the machine has been running linuxcnc with the 7i43+7i33+interface pcb without any problems in the lab again. The current load of the machine ( uptime/top ) is about 6, and I still have a working realtime for almost two days now. Summarizing all replies, ideas, questions. 1. Ntp/network is a good idea, since I do have this setup via cron to check the time every 20 minutes. However, these ntp updates happen also in the lab, and there I don't get any watchdog bite. Anyway I'll disable the ntp updates and see what happens. 2. Yes, I should have saved the output of dmesg. I checked it, but did not save it. There was no unexpected realtime delay message, that I do remember. I will save dmesg's output next time. 3. I am running a 1ms servo loop on two other linuxcnc machines with 7i43+7i33. A 1ms servo loop only works for me with onboard lpt ports. I had no such luck with pci boards. I must say that I have never checked with pci-e cards. When building a pc for use with linuxcnc I just always make sure to have an onboard lpt port for the epp communication. This a dual core machine at 3GHz that I am using, so there is enough cpu power to spare, even if one core is busy with the servo loop. And after Friday's email to the list, the last thing I tried was running with a 5ms servo loop and the watchdog did bite again. 4. Monitoring the epp communication with a digital scope would be an option, I don't have one myself, but I know somebody how does. Certainly it would make sense to see if the communication really breaks down for over 500ms. But I know nobody who owns a logic analyzer, so I can only check 2 chan max. What pins on the ribbon cable are the most interesting ? 5. EMI certainly/unfortunately is a possibility. The ribbon cable from the pc to the 7i43 is short, about 30cm, but who knows what kind of EMI I do have in a 30y old mill. And of course the ribbon cable is not shieled either. I tried running with the converter for the spindle powered down, but that did not help either. 6. The 7i43's watchdog timeout I first had set to 5ms, then 100ms and increased that value to a final value of 500ms. And still I got watchdog bites at a timeout of 500ms without any unexpected realtime delay message. Of course, once the watchdog bites, I get following errors too since the axes don't move anymore once the watchdog has bitten. 7. I will try to decrease vm swappiness from 60 (ubuntu's default) to 10. The machine has 4Gb ram of which only 3,5 are useable because of the 32bit architecture. The linuxcnc pc never runs anything except linuxcnc, so it should never swap anyway. 8. External events. I could use the 7i43's hm2_7i43.0.watchdog.has_bit pin as a trigger for halscope, but what other events should I monitor in halscope ? Halscope can only monitor a maximum of 8 channel, I believe. Or does somebody have an working example of a streamer/halstreamer setup that I could copy. Anyway, what other values from hal space would be interesting to debug this ? Ferror, cmd pos, fb pos, velocities, accel for all axes, pwm values, the watchdog has-bit pin, the io_error pin, and what else ? 9. Question. Since I don't have an io_error 16 bit RW FALSE hm2_7i43.0.io_error and the documentation at http://linuxcnc.org/docs/html/man/man9/hm2_7i43.9.html tells me that the io_error should be set if I do have a broken epp communication, does that mean that I can rule out EMI on the cable from the lpt port to the 7i43 ? 10. I could buy a pcie lpt port and see if that helps. 11. Video drivers are vesa, no nvidia hardware. No flash, no firefox, nothing but the linuxcnc ubuntu 10.04 32bits and the cnc software running. 12.

Re: [Emc-users] 7i43 watchdog has bitten, looking for the cause ?
Hello Peter, One thing to verify once you get a watchdog has bitten error is to verify if that its a real watchdog bite or whether its somehow a false noise generated report. Can you toggle any I/O bits (via halcmd) after the watchdog has bit event? I do have leds on the digital outputs and inputs that use on my custom pcb machine interface. Once the watchdog bites, all signals (inputs and output, haven't checked pwm and encoders) then have the led switched off. And I do at least have always the EstopWrite and EstopSense and AmpEnable leds switched on and shining while the machine is running normally. But I have not tried toggling digital outputs via halcmd after the watchdog bite. Just to be sure, you mean toggling the output *before* I reset the watchdog via halcmd setp hm2_7i43.0.watchdog.has_bit 0 ? If you can, the report is bogus. I really dont expect this is caused by noise but this is pretty strange (never heard of a similar watchdog issue) Yes, it is strange :( BR Max. -- AlienVault Unified Security Management (USM) platform delivers complete security visibility with the essential security capabilities.

Re: [Emc-users] 7i43 watchdog has bitten, looking for the cause ?
Hello Dave, no, there is no usb device connected at all. Mouse and keyboard on PS/2. I always try to avoid usb with emc2/linuxcnc since I was once burned by a Pentium II mainboard that had strange usb issues with realtime. However, your idea does have merits. There might be a faulty device that does drive me nuts which is not connected to usb but somewhere else. I will check interrupts and their frequency. Maybe something is wrong there. BR Max. I'm hesitant to ask this but... any chance you have a USB connected device that is either not plugged in entirely, intermittent or flaky?

[Emc-users] 7i43 watchdog has bitten, looking for the cause ?
Hello, I have a old mill that I want to use with linuxcnc. I have prepared a pc with a 7i43+7i33+custom pcb to interface the mill. That pc with the interface I have both tested with the latency test and also with 7i43+7i33+pcb and the output for EstopWrite connected to the input of EstopSense in the lab for over *two weeks*, not days, with no latencies at all to speak of. Max. latency with huge load of IO was in the order of a few tens of microsecs, so I expected no problems. I use a servo loop of one millisecond. Now when I connect the setup to the mill I get bitten by the 7i43's watchdog within maybe an hour, often much earlier, and I have already increased the watchdog timeout from 5 milliseconds to 0.5 seconds, i.e. 500 milliseconds. I am a bit out of ideas of what could be the cause for the watchdog biting. The lab setup runs fine with latency test, the pc+7i43+7i33 on the lab bench with the servo calculations running also makes no problems. I am getting no message of unexpected realtime delays in axis or in dmesg when the watchdog bites - which I would also expect when the watchdog is not pet for 0.5 seconds. Finally is there an IO pin in the motion module to which I can connect the 7i43 watchdog's has-bit pin ? Both to use the message to generate an estop and to be able to reset it ? I looked at the pins of motion at http://linuxcnc.org/docs/html/man/man9/motion.9.html, but could not see something suiteable. Because right now I have to manually halcmd setp hm2_7i43.0.watchdog.has_bit 0 in a terminal, and I would like to be able to reset that when I get out of estop.

Yes I could add it to the estop chain, however I don't use the classic ladder and I thought that there is maybe a special pin for the watchdog to generate a more descriptive error other than just plain estop. You could also add some other logic to reset the watchdog when you leave estop, but i don't think you should. The watchdog should never, ever bite, and it shouldn't be a routine matter to reset it. Let's figure out why it's biting, and fix that problem. I agree that the watchdog should never bite and I am aware that I could write a custom .comp for it and tie that into the estop chain, which I'll probably do. The thing is that I'd rather continue the job if I can and not throw away the material, makes my purse weep ;) If it helps, these are the 7i43 pins after the watchdog has bit, unfortunately I don't know anymore if I had pressed the estop button or not. 16 s32 OUT-1 hm2_7i43.0.encoder.00.count 16 s32 OUT 0 hm2_7i43.0.encoder.00.count-latched 16 bit I/O FALSE hm2_7i43.0.encoder.00.index-enable = Xindex 16 bit IN FALSE hm2_7i43.0.encoder.00.latch-enable 16 bit IN FALSE hm2_7i43.0.encoder.00.latch-polarity 16 float OUT -0.01 hm2_7i43.0.encoder.00.position == Xpos-fb 16 float OUT 0 hm2_7i43.0.encoder.00.position-latched 16 s32 OUT-1 hm2_7i43.0.encoder.00.rawcounts 16 s32 OUT 0 hm2_7i43.0.encoder.00.rawlatch 16

Re: [Emc-users] Mesa 7i43 and estop
Hello Bruce, I am running a Mesa 7i43+7i33 servo setup myself. If you press estop, or if estop is generated through the estop chain, then you do not loose position. To loose position on a rotary encoder or linear scale with a 7i33 you'd need to switch off power to the 7i33, which should trigger the estop. If you do only loose power on the rotary encoder or linear scale then the position will not be updated anymore. BR Max.

[Emc-users] /etc/update-manger/release-upgrades: Prompt=lts = Prompt=never
Hello, while there is a too big to miss notice in the wiki that upgrading from 8.04 to 10.04. will break things-which is all well if you are yourself the well informed operator of the machine-it will happen somewhere ;) Needless to say I had to write back a backup after I had the case of an machine operator starting said upgrade last week. I found that there is a switch for the update notification in /etc/update-manger/release-upgrades Changing it from Prompt=lts to Prompt=never will elimate the risk of accidental upgrades from the gui. I haven't tried yet if this will work in 10.04 and 12.04, but perhaps this could please be included in a future version of the ubuntu linuxcnc installation cd ?

Re: [Emc-users] 5i25 detected, but not the 7i77 yet
Hey Peter, Hey List, I wrote my standalone pyvcp panel which runs with halrun only for my lab setup and everything looks good at this moment. I ordered the 5i25 and the 7i77 together some weeks back. Not having the correct firmware does not matter, since I now know how to program it anyway. So a very big thanks to Michael Geszkiewicz for writing the linux flash program :) BR Max.

[Emc-users] 5i25 detected, but not the 7i77 yet
Hello, I have now spend the last few hours trying to create a first lab setup with the mesanet 5i25 and the 7i77, but the 7i77 is not recognized at all. In general I have been setting up and running a few machines with the 7i43 cards since 2008 now-so I am not a total noob. The 5i25 is installed in a pci slot. The 7i77 is connected to the 5i25 with a ribbon cable that is connected to the P3 on the 5i25. W2 is down,i.e. the 5i25 does not supply +5V to the 7i77. The ribbon cable is 45cm long. Pin1 on the 5i25's p3 db25 is on pin1 on the 7i77. The 7i77 has +5V and GND on TB1 and +12V on TB2 (12V on pin1 and GND on pin 8.) W1 is on the left side, i.e. VIN gets power from VFIELD. W5 is on the right side, i.e. the 7i77 uses power from TB1. Measured voltages are +4,98V on TB1 and +12,02V on TB2. The computer runs ubuntu 10.04 32 bits from linuxcnc installation cd. Linuxcnc is at version 2.5 from the repository. The 5i25 is installed in a pci slot and recognized when I loadrt hm2_pci without any num_encoders in the config parameter. But from various post I see that the 7i77 should be recognized when hm2_pci is loaded, which it is not in my case. LEDs CR1, CR7, R61 and CR3 are lid up on the 7i77. Can somebody perhaps point me in the right direction ?

[Emc-users] Mesa 7i43 fpga internal input pull ups - could sb synthesise another firmware for the 7i43 with pull downs for GPIO pins please ?
Hello List, I have run into a problem with my new revision of my pcb which adapts a 7i43 and a 7i33 to a machine of mine. Before I had W3 in the up position, which enabled the pull ups on the 7i43. Then I inverted the polarity of the outputs in the hal layer,i.e. the output signals where active low. While designing the new pcb I thought I'd get rid of the inversion of the polarity in the hal layer and designed the output signals to be active high. Turns out that this was a *bad* idea. Now I running into the same problem as Malte on the 11th of this month in [Emc-users] Mesa 7i43 hostmot and EMC2 exiti,i.e. once emc2 unloads the watchdogs bite, all output are reconfigured as input. The internal pullup drive the pin high and all my outputs on the pcb are enabled. Now I was looking for a quick fix and found lines like these in the 7i43.ucf. These are the pins that I use for outputs. Pin numbers are 24 to 31 in the hal layer. 7i43u.ucf:NET IOBITS27 LOC = p27 | IOSTANDARD = LVCMOS33 | DRIVE = 24 | SLEW = SLOW | PULLUP ; I am hoping that putting PULLDOWN here instead of PULLUP would solve my problems. Could somebody comment on that ? As anybody tried ? Could somebody synthesise a new firmware for me with these pins having internal pulldown instead of pullups.

Re: [Emc-users] Dell D610 laptop success?
Hello, I tried a Dell Latidude D600 about 8 months back with EMC2 10.04. The D600 is the predecessor to the D610. They have the same accessoires, docking station, screen. CPU and mainboard are different, afaik. I could install without problems, but the laptop frooze after a few hours of usage of EMC2. Latency test was ok for using servos, too. This did not happen with a normal ubuntu installation, so I think that the freeze was due to RTAI. I never investigated further into the cause of the freeze after a few hours. Might have been power managment issues, fan speed control, etc. BR Max. Peter, I have a very old Dell Latitude laptop, so old I forgot the exact type :) but I run EMC on top of it reliable and with very good latency numbers. However, I had to make a little script that does two things: 1) Turn on the fans at full speed. 2) Turn of SMI (System Management Interrupt) With the Debian CD (6.x??) I couldn't run RTAI, however with my own compiled kernel it worked flawless.

The wiki and the email archives will give you a sense of the general disfavor of laptops.

Re: [Emc-users] EMC2 10.04 sim problems
Hey David, I use emc2 inside virtualbox myself for compiling emc2 and building deb packages inside the guest os for myself with the tweaks I need. That way I can do this on my work laptop in a stable environment even if I have other versions of Ubuntu (like 10.10 amd64) running as the host. Attempting to run any real cnc machine in any vm is asking for disaster, even if you'd manage to get communicatations with the real io to the cnc machine in the first place. However the simulation is practical for designing your own pyvcp panels in a silent office as opposed to a noisy machine shop. I haven't yet tried to run 10.04 with emc2 as a guest under virtualbox as Mark tried. So I cannot comment on that. It also depends on which architecture is used (x86, amd64). As I understand it, the 10.04 emc2 is not generally working in amd64 arch yet. Cheers Max. Hello All, Please excuse my ignorance, but why would you want to install EMC2 in VirtualBox ? I would have thought, with my admittedly limited knowledge of Linux, that doing that would be like playing Russian Roulette with a loaded machine gun?

[Emc-users] nasty bug in the stg driver: dac output voltage wraps around for min. commanded value to max. possible value
Hello Everybody,
after noticing some bad noises on a machine I noticed that when I
command an output of -10.0V on an stg2 card that it actually outputs +10V.
To debug and reproduce I did this:
setp stg.2.dac-value -10
or
setp stg.2.dac-value -9.999
measured approx. +10V with a voltmeter, not ok
setp stg.2.dac-value -9.99
measured approx. -9.96V with a voltmeter, ok
Such large values should not usually happen if you use the dac output
for a servo amp because then you've run into saturation, but if you use
the output for something else, like spindle velocity control+ direction,
then it really does.
The relevant code is how the ncounts variable gets
calculated in hal_stg.c:
ncounts = (short) ((-10.0 - volts) / 20.0 * 0x1FFF);
The relevant stg documentation is on p. 30 of the stg2 manual. Values
written to the register are inverted before arriving at the dac.
0x = -10V
0x1000 = 0V
0x1FFF = +10V
Changing the calculation to:
ncounts = (short) -10.0 - volts) * 0x1FFF) / 20.0) - 1 );
solves the problem. Check with the attached test program. Notice the
0x values for -10V after the inverting is done in the old calc.
Current Emc2 calculation: Values written to register are: -10V: 0x,
-9,999V: 0x, -9,99V: 0xFFFC, 0V: 0xF001, +10V: 0xE001
Current Emc2 calculation: Values arriving at DAC (inverted) are: -10V:
0x, -9,999V: 0x, -9,99V: 0x0003, 0V: 0x0FFE, +10V: 0x1FFE
Mod. Emc2 calculation: Values written to register are: -10V: 0x,
-9,999V: 0x, -9,99V: 0xFFFB, 0V: 0xF000, +10V: 0xE000
Mod. Emc2 calculation: Values arriving at DAC are: -10V: 0x,
-9,999V: 0x, -9,99V: 0x0004, 0V: 0x0FFF, +10V: 0x1FFF
I also checked this fix 5 mins ago on the real machine - works now.

Re: [Emc-users] PROGRAM_INCLUDE_PATH in addition to PROGRAM_PREFIX?
Hey, I like your idea, which is interesting to me because I currently keep the user defined M100+ files are in the same directory as the other ngc files - which is not a good idea since ngc files sometimes need to be deleted or changed, but the M files should be kept immutable. So if PROGRAM_PREFIX could be made a list of directories, that would be really a good idea. Just for O files I think it is possible so use WIZARD_ROOT even if that variable in the ini file might be intended for something else (interp_o_word.cc). BR Max. Let me first state that I love EMC2, it is awesome etc. I have recently discovered that EMC2 G code is a full fledged programming language with subroutines, conditionals, named everything, etc. Since then, I have been happy as a clam and writing G code functions for pocketing, facing, etc. So do not interpret the foregoing as some kind of a negative. I do feel, however, that EMC could be slightly enhanced to take an optional argument such as PROGRAM_INCLUDE_PATH, that would list a number of directories, separated by ':', that would be searched with subs are called or files are otherwise needed. Without that, program_prefix is a hodgepodge of all sorts of stuff instead of keeping things properly organized. Also the path to open scripts could be different from the path to keep functions. Alternatively, specifying directory path when invoking subs, could also work. Also if this is already provided, I would love to know.

[Emc-users] SPI bus communication with mesa cards ?
Hello Everybody, I'd like to use some extra ICs to read an ADC at a relatively low speed to get some values from potentiometers. And I2C or SPI integrated circuits are quite common. I currently have a mesa 7i43, 200k and 400k versions with an extra pcb to adapt to the cnc machine. I'd like to put an extra SPI bus on my own pcb, connect some ICs to the SPI bus an happily read and write to these ICs. Is there any work already done in the hostmot driver for the mesa cards ? I've seen the page in the wiki, but I think this was just more or less a brainstorm on how this could be done. How about a software implementation of the spi protocol. Has anybody worked with that ? How fast could you go with a sw impl. ? BR Max -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Re: [Emc-users] Servo cycle times for pci parallel cards and mesa 7i43 cards
Hello Jon, 0,5 millisecs is quite good. I was asking because I could get the Oxford PCI840 to just about 10ms servo cycle time before the driver would cause an error.

The PCI parallel port should be a little faster, I'm sure you could go to 0.5 ms and probably even higher. I'm not sure whether this will be any advantage, though.

Re: [Emc-users] Feed word
Hey Steve, have a look at the interpreter source file interp_convert.cc, function int Interp::convert_straight. The piece of code that you probably want to change is this one: START_SPEED_FEED_SYNCH(block-k_number, 0); Just as a try I'd suggest you change that to: START_SPEED_FEED_SYNCH(block-f_number, 0); and then recompile. Also do change the code for G33.1 a little bit later on in the same function. BR Max Hi guys Can somebody explain why K was used for Feed in G33 move and not F ? I'm finding it impossible to produce a turn post processor because of this. I can get my CAM to put the K in, but it also puts the F in too! Is there a particular machine this was based on then I can look at the post processor for that. Another weird one with feed is it appears not to be modal if you do an arc then a G01 - emc moans that there is no feed set on the G1 line?

Re: [Emc-users] Using M64, M65 and M66
Hello Eric, please have a look at the motion.digital-out-XX pins in hal and the num_dio parameter to the loadrt motmod line if the default number of 4 dio pins is not enough. I think the num_dio parameter is a fairly recent feature enhancement, so you should run a 2.3.something version to use it. http://www.linuxcnc.org/docview/html/man/man9/motion.9.html BR Max. Hi all, The documentation here: http://www.linuxcnc.org/docview/html/gcode_main.html#sec:M62-to-M65: Describes the use of M62-65 (really only M64 and M65, the user's manual states that M62 and M63 are not implemented) as follows: quote To control a digital output bit, program M- P-, where the M-word ranges from 62 to 65, and the P-word ranges from 0 to a default value of 3 in EMC2. If needed the value can be increased by using the num_dio parameter when loading the motion controller. /quote I may have missed a bull fiddle in a telephone booth, but I have so far not found a description of how the P-Word value is mapped to a specific HAL output, or in the case of M66, a HAL input. Any pointers would be appreciated. Regards, Eric -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

[Emc-users] O-words with n-words, patch attached
Hello,
i am still using n-words ( line numbers, old habbits die hard ).
However when the line contains o-words, currently (2.3.1) no other words
may be present.
The attached small patch to Interp::read_items allows o-words with
n-words without changing any other behaviour (methinks).
Would you mind including it into the main source tree ?
Sorry to put this on the main user list, but i do not know who to ask
specifically for this. I have more small code changes for the rs274x
interpreter, who is the right person to talk to ?
Thanks
