Mk1 does not support THC function, which is used with external THC controller that controller the Z axis so that machine is cutting always on the same distance from the surface.

Our Mk3 series of controllers support G10 g-codes which can be used in the beginning of a program and can initiate the offset measurement and offset setting. The absolute value for Z is changed but you could use it like you have mentioned.

Greetings, I have a USB controller by probotix (PBX-USB). Does this board support the Z floating head feature?

Best regards.
