Hardware troubleshooting

PowerOn problems:

Unwanted powerOn and bleep at poweroff

Measure resistances between legs of TIP127. If the resistances is below nominal values (they could be different up to 100 ohms) :

or there is short between other legs, you need to replace TIP127.

Problem could be related with Issue #51. For me it started happening when board started to measure really high temperatures(140C) and powered off.

Motor problems

Motor has no torque

There could be a couple of problems related to this issue.

1. Broken/badly soldered phase wire. Especially if you are using self made extensions or replaced connectors.
2. Burned/damaged motor coils. (There is a possibility but very low, as no one has encountered this issue yet)
3. Burned mosfets. Check with diode mode.
4. Bad code.
