Heaters will not turn on

@kvi94 yes you can use the VIN ground terminal, or the middle pin of any of the IO connectors.

@dc42 Please find below the voltage of the resistors when both output are off.

R40 = 0.001V
R115 = 0.025V

R53 = 0.032V
R57 = 0.001V

@dc42 I managed to measure the voltage when the heaters are in active state by the firmware, the reading are as follows:

R40 = 0.001V
R115 = 0.025V

R53 = 0.585V
R57 = 0.004V

@dc42 did you manage to take a look at the values? What does it suggest?

Thank you.

@kvi94 if you are sure that the heaters were on when you took the measurements and had not yet faulted, then it looks like those drivers have failed. Please email warranty@duet3d.com with a link to this thread.

@dc42 I had someone to keep an eye on DWC for any fault while I took the measurements, so I am pretty confident they had not faulted.

Alright, I will get this done.

Thank you.
