Skip initial sensing was created by wasausky
Hi everyone, I have 3 questions
-How can I omit the initial sensing that the plasma torch does?
-How can I prevent the torch from rising when a problem occurs or simply pauses the program.
-Is there a way to move the z axis while the program is paused.
Thank you for your answers

If you can describe what you are trying to achieve we may be able to help.

Currently there is no way to omit it, you may be able to create a fake ohmic or float pulse with a bit of HAL magic.Hi everyone, I have 3 questions

Currently there is no way around this.-How can I prevent the torch from rising when a problem occurs or simply pauses the program.
You can use external offsets, this is how plasmac does it, so you would need to do a bit of HAL work to implement it.-Is there a way to move the z axis while the program is paused.

All of the above can be done by simply using a normal config, not PlasmaC or QtPlasmaC.

my purpose is to make a machine for oxy fuel. According to this video in the pause the z axis does not move up when pausing, in addition to being able to recover the cut and it does not have the initial sense when firing the torch again.
There will be some configuration for oxy fuel even if it is not plasmac to be able to recover the cut, or as it would be implemented in a normal configuration.

A standard/normal config will work just fine, i have several plasma cutters in use with oxy at client sites, all have a normal config for oxy and PlasmaC or my old config for plasma.
The only usable feature would be adding "reverse run" and setting the Z axis in hal to use external offsets and make small adjustment in height during cut. The latter is not important at all for thin sheets, thin being 20-30mm, as several mm in height have no impact on cut quality for oxy.
Adding pause to preheat the material is a s simple as inserting
G04 P900
for 15 minutes of preheat.
Also a G1 Znnn with a slow feed can be added when piercing so the torch lowers slowly to prevent molten metal hitting the nozzle.
