I am trying to test the extruder, and it stops at 100c and says heating failed.... Any Ideas?
Just tried on Extruder 2 and it failed 93C...
Have you checked the connections are not lose?
Nothing seems loose...
No fans on blowing at the hotends other than the hotend heatsink fan?
Nope, it seems to take a very long time for it to heat up, are the hot end fans supposed to be on full blast?
yup they are always on full.
I know I mentioned the wires before, did you check the input from the PSU at the time too?
Yup, those are good. It starts off heating well, going up about 2c every refresh and then it really starts to slow down around 80c
can you unplug one of the hotends from the rumba and have another go?
Trying it now, I was only doing one hotend at a time. I am uploading a video to youtube to show you how it is heating up. Will post the link when it is finished.
This didn't work.
This is how it heats up, not sure if it will help or not
Try with the bed not heating to 120 ?
Just tried it with only nozzle 1, nothing else and same thing.
What about just heating the nozzle and not using the presets?
You can set the temperature via the control menu.
Yup, did that and same thing. Would upgrading the firmware help at all?
My only other thought is have you not assembled the hotend correctly? A firmware upgrade shouldnt help, the PIDs that are in there by default too will definitely heat it up okay too.
There really isn't a good way to mess up the hotend... It looks just like manual... The heater and the PID are clamped in very securely... I don't understand... The fact that it is both of them makes me think it is something else...
Maybe the PT100 PCB's aren't reading it correctly... I'll tape a thermocouple to it to see what temperature that is reading...
Does it read ambient conditions correctly? Set screw holding the PT100 snuggly in place?
May be worth reading the resistance of the PT100 as well to see where the issue lies. Would be especially beneficial at "temperature"
They are tight, and it reads 18C ambient which is what my house is. I'll measure the resistance when I get home. This is frustrating.
