This week I updated our UM2 to firmware 14.03 and immediately ran into a problem, when starting a print job, the printer would start printing without even heating up the nozzle. So the UM2 would just go through the motions without releasing any material. Manually tuning the nozzle to 220 degrees, did help, but its not the way to work I guess.
I downgraded beck to Cura 14.01 and installed its firmware and it was all back to normal. But the file I saved with the 14.03 version would still print without heating the nozzle (it even displays no further information on the display when selected from the menu on the UM2)
any thoughts?
