Trying to fix our plasma table and we are running out of ideas. Running a HPR260xd on a Hornet gantry system.

Finished a cut on a sheet. Operator came back and it was in the air with no error fault. Operator changed consumables. When you hit start run, you can hear gas, you can hear the main power relay pull in. The head will go down, press into the material, and then rise back up. No error code at first. Occasionally we get a "Start Lost" error code.

Ohmed all the lines and grounds. Replaced one board already.

Any ideas would be of great help.
