how hacking you mean please? Of course at the earliest I start debugging about USB connection and configure opi (power supply and etc) What happens exactly? - Printing stops in the middle of print job but often after print job it is impossible a new assign print job in the octoprint... :-( Exactly not working preheat bed and after I can see error message that Z switch is broken... I think that is problem mainboard and USB connective. Z stopper is normal without defect. I read in the forum that - print-over-USB for the Ultimaker 2 is currently not "officially supported" by Ultimaker...

This is exactly the problem, I have the octoprint but a have problems with USB comunnications betwen manboard and rpi :-( purely and simply i want make adjusments or replace motherboard with supported wifi. if that is possible? Thanks
