Geeetech

how did you solve the problem

Having the same, took the complete head in part, resoldered every wire and connection - still the same

Admin - any help ? any advice?

I guess Geeetech is not really interessted in our problems and questions will not be answered?

What causes the 0.Temp reading on the nozzle and how can we fix it?
do you have the board with the 4 contacts, where the nozzle gets its contacts when engaged?

Thanks

did anyone ever got help on this problem with 0 Temp on the Nozzle?

I have tried 6 nozzles, all the same problems. I took the complete head apart and resoldered every wire, every connection on it, traced all the wires down to the main board to make shure, no brocken cable. Put it back together ...
