Hi,
I have a RUMBA board (using Repetier firmware and client). The heating resister is not heating up.
It used to work OK but something (don’t know what) went horribly wrong and it overheated & blow the T0 Thermistor connections (so they no longer acknowledged when a thermistor was been connected). I solved that by changing pins.h to use the T1 thermistor connections. The thermistor readings work just fine now.
But now neither the T0 nor (having changed pins.h again) T1 Heating resister connections heat up the resister (I've tried several and checked the connections are OK).
I connected a multimeter.
- With the ‘Heat resister’ button off it reads: resistance
- When I ask Repetier to heat up the resister it reads: 0 resistance
(I’m thinking I should be checking voltage or something but didn't get anything helpful – but quite possibly since I wasn't sure what to set my multimeter to)
So, it’s trying to do something but not enough power is getting through????
Is that fried? (T0 and T1 heating resistor connections?)
Any ideas?
Thanks
Pete
