So, i just upgraded to Volcano on my E3d. Calibrated the Z-probing and print height. After that i upgraded my Firmware and the Webif. Now the extruder turns of at the start of a print. I can still print but i have to quickly turn the extruder heater on agian or the printer halts on temperature.
Cant find a thread with this topic. I run Cura as a slicer and have not changes any settings since before.
EDIT: I also did an auto tune for the extruder.
