Hi all I am looking for a little help with my Alfawise U20 last week the extruer overheaded and started to smoke. I noticed that the small white wire had come loose from the heater block so today I changed the entire hot end.
I am now getting the problem that what ever temp I set the extruder to the actual temp goes sky high.
so for example I set the extruder temp to 200 and the actual temp went up to 250 and stayed that high.
any help with this will be very much appreciated
