17.10.1 UM2plus - er07
Hi, I just tried the 17.10.1 release on my Ultimaker 2+. The printer is unresponsive since trying anything (print, home head, etc) just throws the ER07 (X or Y Switch Broken). Rolling back to official firmware solves the issue.
I got the same problem at first: you need to factory reset after flashing. See https://github.com/TinkerGnome/Ultimaker2Marlin/issues/77
