Thanks for replying. Not sure what components this machine uses, but the producer mentioned "second generation" thus I was thinking they were referring to the UMII. The machine was delivered with the Ultimaker software (CURA), and the manual specified to select the UMII for slicing...
However, the menus / setup etc etc. is terrible, it won´t even return to "home" after having printed. We also have a Makerbot here, and although the MB is quite basic as well, it´s a supercomputer compared to this one..... Anyhow, the print-surface of 200x300x360 is what made us purchase one of these for testing-purposes.
I guess I would need a new driver for the X-stepper-control. Where are those normally located? I did not see any on the front-section of the motherboard, perhaps I need to loosen the board?
