Extruder Stepper motor fail

[markus_kyroe]

Hi,

Finally I have got time to finish my upgrade from 1.0 to 2.0.

Everything was ready before the test run. When I wanted to get some fillament though the extruder - after some time this started happening: http://www.youtube.com/watch?v=470UHVp_ ... e=youtu.be

The stepper motor seems to clog and says this unhealthy sound - and keeps on doing this

What to do?

can you turn motor by hand ?
are you shure about the wiring , connector on printed circuit board , check, plug out in ....
try to adjust the small pot on the print to set current limit...

if it worked in version 1.0 it should work now ! no panic.

It it pretty difficult to check if I can move the motor by hand as there is no space around it for me to grab - any tricks?

Pretty sure about the wiring - it worked fine the first 5 minutes. I'll try to adjust the pot when I return from christmas holiday. I'll keep you updated - thanks for the answer and happy christmas!

I unmounted the wires from the extruder motor and mounted them again - IT WORKS NOW - and the test print worked perfectly.

Thanks for the help
