I did load the changed xml file for the mill profile and it works fine, that problem is solved.
Next problem to solve: the breakoutboard (STB4100) does not have any power on the connector for the spindle speed (00-10volt)

all done?

Thank you, that's the manual I used and checked the settings already 3 times, still no power on the 0-10 volt pin (DAC).
I ordered a new one, because I think that mine is not working and in order to have one to play around with in the office. It is quite cold in the workshop to seat and program and the machine is to big of the office...
The new one will hopefully arrive on Friday, so that I may test it over the weekend.

Currently I try to work out the frame to build on. Currently the prototype is build out of wood (left overs). So I will have to change that to aluminium and hopefully I may produce the needed parts already with my prototype.

Got the new board, and now it works partly, got power on the pin (0-10) and the inverter reacts accordingly.
Still the spindle does not react, so I guess this is a setup problem with the parameters of the inverter, still investing.

Does any one may tell me how to connect plasma to the board? It seems that a relais is needed to use the 5 volt signal to switch on the 220 volt switch for the torch.

normaly the torch ON button from the manaul torch is "emulated" by a relay contact.

I plan to use this one:

1 Canal Relays 5V 10A High und Low Level Trigger Optocoupler.
Hopefully that's the right one.
Still wondering how to connect as there are 3 pins each side.
