Some thoughts and some findings using PlasmaC

On my config it will disable everything requiring F2 to be pressed to continue, also an error is reported as joint3 in my case.

Interesting, I've mentioned similar to Phill. I think I see this as well, it manifests as joint 3 following error for me, and it's the only axis (Z) I have trouble with, and it's ONLY in the up direction, and only when PlasmaC is in charge of the torch.

Manually, I can jog (rapid) the torch until I'm blue in the face and I never get an error, it's only when PlasmaC is in charge, and only in the up direction. Also, my accelerations and speeds are higher for the other axis' and I don't see following errors.

I concur that lowering the acceleration and setup speeds does make it less likely to occur. Right now Z is pretty tame, but what I built is capable of much more.

At any rate, just wanted to drop that in here in case it helps at all.

And that made you happy?! :laugh: Am I going to have to start looking over my shoulder???

This is to awoid arc lost issues caused by unshielded and cheap proximity sensors as they are usually located near the torch and i did encounter that issue.
Tom.

I also had problems with this, since I have a plasma with hf ignition, the float-switch sensor was triggered every time during ignition!
I solved it by adding another dbounce for the float-switch. And when the Probing, signal comes through dbounce with a value of 5, and when the torch is on, the signal comes through a dbounce with a value of 500.

One more note for pierce/cut mode. When in the Gcode is present the spotting function and turn on the "Pierce only" mode the plasmac makes piercing instead of spotting.
It would be great to ignore spotting when "Pierce only" mode.

And thank you all for the work done, I'm excited about the plasmac, although I am still working with an external THC.
