PlasmaC has nothing to do with trivkins, I don't know what that would be about.

Could you post your compressed config directory.

Edit:
Just to make sure we are on the same page I installed 2.9 from the Buildbot then installed the new plasmac.comp, edited plasmac.tcl as per the earlier post and I cannot get it to fault, it appears to do everything it should.

I am unable to get that line put in. I get an error on boot. See below. If I comment that line out then I can run the program but the z axis doesn't move from the home position. No probe function or any other.

i get this error when i try and run an actual.machine. and not a sim.

im unable to test on my machine other then simulations for now. i should be up and running for testing tommorrow. :(

The error message is telling you that the pin halui.machine.is-on is being used elsewhere.
The new PlasmaC.comp uses this pin to clear offsets.
You need to find where else it is being used and change that Hal file to suit.

Edit: comment out line 291 in cnc_plasma.hal
Code:
net machine-is-on halui.machine.is-on

Got that corrected now. It runs a full program! Woohoo. Unfortunately it only will run 1 full program for every total restart of the computer. Odd but it's letting me limp by and get this job done.

It does the same thing where it will retract to home after the job is complete and then not move any further with no jog control. I also still get nan every once in a while and have to restart linuxcnc until it goes away.

Can you explain what is happening or not happening, I can run one gcode file several times and can load a new program and run that. I am using the config you posted last.

Any error messages in the terminal?

Edit: you need to switch to manual mode to jog.

Edit2: In cnc_plasma_connections.hal try commenting out this line:
Code:
setp plasmac.lowpass-frequency 2

Purduepete's current configuration attached. lowpass is set to 50, debounce is 5,

how do i run his specific config as is, as a simulation? so i can poke and prod to see if i can get it to misbehave?
i was going to configure my 7i76e to match his setup 100% and try that to simulate his problem. (seems overkill but im half way to assembled)

Phillc54, I actually thought it was all good. If I run a program it runs fine with the torch off. No issues. If stopped in the middle there are no problems. If it completes no issues starting another. But when a cut program is run with the torch on only that program will complete. Runs great the whole time for the most part, I'll circle back to this, but after that program it will only do the first cut and then will do what it has been doing not moving after pierce.

I did have an issue running some 3/16 plate. Was trying a few different things and bumped my lowpass to 50 from 2 and debounce to 5 from 50. Because the THC was a lot more responsive it dove at the end cut when it hit a pierce. After it did it 3 or 4 times it retracted to its safe height and would not allow jog or anything after killing the cut program. Required a computer reboot as well.

Use the attached simplified hal file instead of cnc_plasma.hal

<machine-name>_connections.ini file:
  • comment out all [JOINT_n] lines begining with HOME_SEARCH_VEL, HOME_LATCH_VEL & HOME_FINAL_VEL
  • uncomment everthing in the ini file [APPLICATIONS] section
  • add APP = halshow my.halshow to the [APPLICATIONS] section if I need to watch any pins

    • <machine-name>_connections.hal file, comment out all lines except:
    Code:
    loadrt debounce cfg=3 setp debounce.0.delay 5 addf debounce.0 servo-thread setp plasmac.lowpass-frequency 0 net plasmac:axis-position joint.3.pos-fb => plasmac.axis-z-position setp plasmac.multi-tool 0

    Why are you changing the debounce value and the lowpass value. Are you taking Halscope readings that show this is required. Everyone I know uses the default values of lowpass = 0 and debounce = 5 which work well unless you have some electrical noise. A frequency of 2Hz seems a very odd number for lowpass and a debounce of 50 seems quite high. I am thinking that maybe you have electrical noise issues that you need to find. This may also have a bearing on the NaN reading that you occasionally get, I have not heard of that on any config I know about.
