Posted: Sun Jan 06, 2019 1:11 am
Hi there,
the termistore in the hotend blew up when i was stopping a print.
Bought a new termistore and change the firmware to 11.
After starting the print, Repetier Host and the display showed the temperature rising to 144/200° there it stayed but the hotend kept on heating.
I realized that as the hotend was smoking.
Then I bought a original hotend from geeetech, changed the termistore value back to 1.
I have startet pla pre heating, and the display stopped again at 144. Hotend kept heating.
Temperature changes to 144 were displayed.
I use the pro w firmware without any changes from this forum and controled the termistores with my multimeter. they seem all to be ok.
Dont know how to continue, please help.
