Hi,
I have a CNC plasma machine that I was very happy with but now I have a problem with it.
Plasma source: Hypertherm Powermax 45xp
Torch: T45m
Control: XPTHC-4H
Software: NcEditor v12 from Weihong
CNC table: downdraft, Chinese made.
PROBLEM:
Normally when I run a program the cutting head makes the IHS (touches the metal sheet and sets the cutting height)
But now the cutting head goes down, touches the metal sheet and tries to keep going down, not sensing the metal sheet.
This problem is not permanent. Sometimes it works.
I have changed the consumables SHIELD, Cutting head, Electrode, Gas ring. (everything is from my local Hypertherm distributor)
My local Hypertherm distributor said that T45m torch is an old torch for Hypertherm powermax 45.
I tried to contact the Chinese manufacturer but they first said I should change the consumable (what I already did) and then they said they don't understand the problem etc.
Can anyone give me a hint what to try and do?
Thanks Dan
