Topic: Extruder motor not functioning?

I've had Repetier on my DaVinci 1.0 for some time now.  I installed the e3dV6 a week ago and printed a dozen prints while dialing in temps.  I unloaded the filament and the motor would only turn maybe a 1/4 rotation ... so I ran the unload command a dozen or so times to unload the filament.  I took apart the hot end carriage to better align the nozzle feed tube with the stepper gearing and reinstalled everything.  At first I was getting a decoupling error and couldn't figure out the issue until I realized I accidentally plugged the PCB harness into the stepper motor.  I assume this has caused some damage somewhere along the line.

Now, with the printer on and I unplug/plug the harness, the motor gives a slight jog ... assuming this is due to receiving power.  When I load the filament, the motor gives no response at all.  When I cancel the load process, the control panel displays 'Action canceled!' and then just sits there forever ... essentially locking up.  At this point the printer is unresponsive and I'm forced to turn it off.

Any help would be very welcome.

Re: Extruder motor not functioning?

Any thoughts?  Can I supply any other info to help with diagnosis?  Do you think it's a motor or driver issue?  Could it be something else?  Again ... any help (even if it's only a hunch on something to try) is welcome.

Re: Extruder motor not functioning?

my gut feeling is a blown driver drivers can be damaged by no motor hooked up or a bad connection . you can do the old motor swap method. with the power turned off swap the extruder motor connector for antother axis then try to jog that axis na try to run the extruder.

You can also swap motor drivers with the power off of course and see if the problem follows the driver..

Re: Extruder motor not functioning?

Many thanks guys!  I'm unable to focus on the printer at the moment, but I'll let you what I find when I'm able.
