Extruder turns of at start of print

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.

What firmware are you running? Have you done a PID tune since changing hotend?

I used the lastest stable version on github. I forget to add that. Yes i auto tuned it as well.

The latest stable version of which firmware?


Moved to the smoothie category for you

Look at the start gcode in Cura, or in the file you are printing. Sounds like you are sending it an M104 S0 in error (or S"some other low value")
