My Rumba my be fired?

Post by somedud3 » Tue Jun 30, 2015 10:32 am

I recently bought a rumba controller board and had it up and running for a short time when all power towards the hotend and fan connector stopped working. Stepper motors are still operational and the hotend and fan controllers are only half lit when code is sent to them. All their voltage read zero.

Stepper can be controlled, it means the MCU of rumba is fine. Was everything fine before?

And, when you test the voltage, the black pen of multimeter should touch GND on PSU, rather than the "-" plus on fan connector, so as for hot bed and hot end.

Ok Fan 0 reads 18v and HE0 reads 24v. I've tested the fan with an external power source and it work so I don't believe the fan or hotend is fired.

These pins need jumper caps:

If the setting voltage of fan is 12V, plug the jumper cap to the slot highlighted in the picutre. If it's 24V, plug jumper cap to the bottom 2 pins.

That is what I have, but another problem came up while transporting the board. One of the M7 fried, so I will try to repair that and see.

Yes it is one of the M7 diodes above the square 5A orange capacitors

Could you please tell me which M7 is fired.
