More feedback here. Customer has an IT savvy brother. His brother told him to lift the torch to clear the stall after reviewing the code and it worked!
It goes without saying, I have asked for a line number reference. :)

I think this implies the bug lurks in the plasmac.comp state machine somewhere.

I've already found my plasmac bug for the day. Maybe someone elses turn!

Since it powers on, try starting LinuxCNC, then try some inputs while checking the "show hal configuration" from the "machine" menu if the LED's toggle.
Chips can be found (i think PCW mentioned somewhere he has some, not sure they are the same though) and are pretty easy to solder on with a normal soldering iron, so give it a try.

Category: Plasmac

The same thing happened on PlasmaC and Phill fixed it, so it is strange that it happens on QTP but not on PlasmaC....well it did happen on PlasmaC, about once in 6-9 months of daily use, while on QTP it would happen daily, several times a day sometimes, then it would not happen for months, then happen again.....
Hence i do not use it on production machines.

I wrote a rant here and deleted it...


Rants don't usually help ... however configuration backups (made from the settings tab) sometimes do. It's hard to diagnose otherwise since Phill, nor I, nor a guy who cut so much plate with QtPlasmaC he was able to sell his plasma table and buy a large fiber laser have seen this issue.

Also, adding the following to your postgui.hal file might help see where it gets stuck as well:
setp plasmac.debug-print 1

Lastly, it's worth noting that plasmac, plasmac2, and qtplasmac all use the same plasmac component at least to the extent where anything fixed in the original PlasmaC was carried forward to the same PlasmaC component today.

If there's a bug, no one wants to find it more than me, but it’s really challenging to identify a bug without being able to reproduce it. Can't squish a bug I can't see :)

Thanks Greg, I've beem away for years and find a bug in 5 minutes 
File Attachment:

In this case the the config to upgrade was nothing more than a sim!
Issues:
  1. The m_files folder was in ~/linuxcnc/nc_files/examples/plasmac, copied it into ~/linuxcnc/nc_files
  2. The files in the m_files folder under examples were owned by root and the user did not have permissions to the M codes
  3. The INI M_CODE variable in the ini file was not updated in qtplasmac_metric_ini.inc. I suspect this was because its not the top level ini file (I'm not sure if you actually write to that folder)
  4. The error message should refer to plasmac so the user knows its specific to Plasmac. I had to deduce that by checking other configs
  5. The version number reported does not reconcile with the version details displayed on startup 2.10.0-pre-4165-xxxxxxxxxxxxxxxx
  6. Let me introduce you to Python try/except error handling www.w3schools.com/python/python_try_except.asp This would ensure the user is less bewildered when it  fails. There is nothing displayed on the screen when it fails
  7. Perhaps the message could be a little more specific eg "updating qtplasmac mcode folder"
  8. Perhaps the upgrade message could also be printed on the console. Displaying Top right when console is in bottom left meant I did not even see the error the first couple of times!
I might add Joco is also in trouble over this for adding these gcodes!

Can Phill or Snowgoer have a look at this issue?


That particular message is to let you know your config has been update to 001.017, and that you need to restart for things to take effect.

If you are seeing it repeatedly, seeing you had a permissions issue in another post, I’d guess you still have some permissions issue(s) going on.

Otherwise if you wanted to zip your config and post it here, I’ll try to make time to take a look.

In particular, that update is looking for 'nc_files/plasmac/m_files' in your USER_M_PATH, to be able to see the Mxxx files. It’s not seeing it so it’s trying to update the ini file to fix it.

Awesome advice! Thank you for the guidance - it's exactly what I needed!

OK, so the cute little Atom board is a no-go. I also have a Supermicro board laying around, with a 6-core Opteron on it. I figured it was overkill - but apparently not!

Yes, Pico Systems' boards are parallel port. However, they are not like typical parallel port breakout boards. They are more like Mesa boards - where the processing occurs on the board. Given the fact that Jon is one of the "OGs" of the LinuxCNC world and happens to be local to me, I've debated about whether to go with the standard Mesa board or a board that might come with more personalized service from the engineer who designed it. I don't want to spend a money on stuff that's already outdated, though.

I will reach out to Mesa, and see what they have to say. Their site has a lot of technical information about their boards, but it's difficult for a "newbie" to interpret.

I was hoping you would say that about a touchscreen. That will make the system a lot "cleaner." Having a wireless keyboard tucked away is a great compromise.

Encoder 2 on the 7i85S is used for the spindle and is actually single-ended, but it's still working fine. So I guess I’ve been lucky there, considering the damage on the board.

I’d really appreciate it if I could get two replacement chips, if it’s possible to have them shipped to Germany.

I meant the BOM for the missing parts. As in all motors, controller boards, cables, router spindel etc.
Might need quite some help with that, I guess

As for the weight, they seem to got there a bit of mixup, I guess the apprentice maintaining the site, missed some spots after c&p :-). IN the end, it will be delivered on a palette anyways..

Sadly the german punctuality has gone big style (the trains are 70% in time at best), but in exchange we got even more bureaucracy.

7i95t pin and firmware files with Stepgens and Inputs 5Axis BoB

Category: Driver Boards

For the parallel port output pins 4 and 5, you would first check
the pinout as  shown previously, this shows that DB25 pin 4 is GPIO 47
and that DB25 pin 5 is GPIO 49

PIN                             GPIO
P1-01/DB25-01          41   IOPort             
P1-02/DB25-14          42   IOPort          
P1-03/DB25-02          43   IOPort       
P1-04/DB25-15          44   IOPort     
P1-05/DB25-03          45   IOPort 
P1-06/DB25-16          46   IOPort     
P1-07/DB25-04          47   IOPort         
P1-08/DB25-17          48   IOPort         
P1-09/DB25-05          49   IOPort    

so

net spindle-cw      => parport.0.pin-05-out
net spindle-ccw     => parport.0.pin-04-out

become

net spindle-cw      => hm2_7i95.0.gpio.049.out
net spindle-ccw     => hm2_7i95.0.gpio.047.out

But there is one more step needed, because GPIO bits default to inputs at startup,
you must set these GPIO pins to output mode:

setp hm2_7i96s.0.gpio.049.is_output true
setp hm2_7i96s.0.gpio.047.is_output true

As far as the connections below  go, they are no longer relevant,
because both the PWMgen generation and encoder counting would likely
be done in hardware:

net spindle-pwm     => parport.0.pin-01-out

net spindle-phase-a <= parport.0.pin-10-in
net spindle-index   <= parport.0.pin-12-in

Note that this will only work on stock 7i95t firmware or 7i95t_5abob firmware
if you disable the stepgens on DB25 pins 4,5 and on.
