Hello. I had received my R2 2 days ago and problems began earlier than I even printed something. I unpacked printer, loaded filament, calibrated Z offset and tried to make first test print. Print bed moved up to the extruder, extruder moved to the front of the printer and straight after that: Error Detected Connection Interrupted I tried to print 5 or 6 times and each time same scenario with errors 'printing' and 'main board not connected'. I checked the official troubleshooting docs and made what they advice. I'm completely new to the 3D printing and would be glad to hear any advice and idea. P.S. Printer came to me with POGO board pins broken. I have already requested from support a replacement.
