I've just installed my Hemera (24V) direct extruder. I'm currently attempting to perform the PID tune on it and the PID autotune times out due to the hotend taking too long to reach the setpoint of 220C. Settings & Equipment Printer: Ender 3 Pro Control Board: SKR V1.4 Temp Sensor is set to 5 in Marlin. Both the thermistor and the heater cartridge seem to be within their resistance tolerance and the thermistor is reading properly when at room temp. I've checked my wiring multiple times as well. As you can see in the picture below, the rise time is way too long to be normal. Has anyone else come across this issue? Thanks in advance (The setpoint here was 220C.)
[Solved] : Heatbreak was too far into heaterblock causing the heater block to be against the extruder housing
Thanks for following up and letting us know what was wrong. You solved the same issue I was having and despite following the instructions troubleshooting this failed because the ONLY thing the instructions say is if you dont get the nozzle fitted correctly you can experience filament that oozes out. It also shows one more total engineering fail of this otherwise awesome tool. However the least they could do is update their already updated instructions to let us know about the potential this can happen (correction.... WILL HAPPEN!) until they finally wake up and actually hire a mechanical engineer that can design and actual functional tool!
