Hotend will not heat up
Posted: Fri Jun 28, 2019 8:33 pm
Hi, can anyone offer any suggestions as to why my hotend has just stopped heating up?
It first of all started by randomly giving me thermal runaway messages halting the prints, then it just stopped heating up altogether,
I have:-
Checked wiring - all cables have continuity
Checked hotend breakout board - continuity from socket to all connectors
Replaced cartridge heater
Replaced mainboard
Checked mainboard fuses - all intact and have continuity
Tried pre-heating hotend - appears no voltage to cartridge heater?
Swapped driver on extruder stepper - no change
I am about out of ideas on this and essentially my printer is useless at this time, if anyone has any suggestions or helpful advice I'd very much appreciate it.
