Strange errors in Master was created by rodw
I'm using Dewey Garret's External Offset branch in masterbut I don't think its the cause
I'm using Gmocappy Plasma GUI
I had a working config and had just about finished adding Dewey's eoffset_pid component for a plasma and all of a sudden everything went to rubbish. I've commented out all of the eoffset_pid code in my hal files and the errors persist and I can't pick up a consistent pattern as I am getting different errors on different runs.

When homing I am getting following errors that are only reported in the console and not in gmocappy and the Z axis moves slowly after a move which is strange.

Here are some examples

And some python errors which appeared after quite a wait.

I don't believe I have touched my .ini file.

So any ideas would be appreciated

I wonder if it really is a Keyboard Interrupt?
Can you try a different keyboard?

Andy thanks, I'll try and dig up a wired keyboard and mouse and see if that helps. There are other factors at play here.
wrong motion mode, change to the correct one
is a gmocappy error and Norbert has acknowledged a bug.
I also have a problem with spurious limit switch triggering that has never been an issue before so I think I need to resolve that first.
In the meantime, I have dropped the use of the eoffset pid component until I get this cleaned up

Rodw, are you geting limit switch errors when firing the torch or with no plasma?
If when firing the torch, that points to bad grounding, so needs immediate attention to prevent from messing up the electronic. I read on another post you had a misshap, so if the errors occur with no plasma active, that is most likely a power supply with bad grounding or with bad capacitors.
To check the power supply for grounding you need a multimeter set at OHM that should give 0 ohms between the ground on the mains side and the - on the DC side without power. To check for bad capacitors set the DVM at AC voltage in a low range something like 2V and measure between + and - on the DC side with the power on and load if possible, it should give a 0V reading or very low voltage ( anything above 0.1V is to much on a 24V power supply ).

Tommy, thanks, I still don't have a table so have not fired the torch in anger :(
I believe I have the 24v and 5v negative rails isolated from the enclosure the plasma interconnect and THCAD will be earthed to but I will check.

The gantry ran perfect for ages and then developed this issue after a short. I have some good quality cable that I'm going to use to make a new cable to replace the cheap manufactured DB9 lead I am currently using before I panic too much (This weekend hopefully.)

It should be 7:43 AM there, right?
I am going in for a shower and bed, woke up way to early today and yesterday so need sleep.
Have a wonderful day.
