No turning motor and extruder heaters not heating

[Mackenzie Liang]

Hello all,
I have a Pro C with the dual extruder, and before it was working fine except the filament was not feeding very smoothly. This afternoon after rewiring the connections (only to make things looks better), nothing works. It doesn't response to home command, perhaps the motors were not running. Even the fans were not running either. The bed can heat up, but the extruder heaters can't. Checked the power supply with a multimeter, it is fine so suspected reason is the GT2560 board, but it's not likely since we just get it two weeks ago and it had only been installed there for couple days. Could anyone suggest anything to test where exactly the problem is? Thanks in advance.

Regards,
Mackenzie

i have a similar issue.
its working perfectly and now it wont extruder the filament for it to print. the heater works everything work. my connections are all good.
WHAT COULD POSSIBLY BE THE ISSUE? i feel like this geeetech printers aren't doing what they are suppose to do. plus geeetech support should just upload the required codes for all printers instead of us running around etc and ending up beig at the same spot of with extra and more problems
