Extruder motor stop/clicking noise

[jedrzejgalecki 0]

The extruder motor makes a clicking noise and stop after

printing a while. What can I do about this?

Hi

If it turns initially then possibly the Pololu driver is over heating

Have a look at it and see if the heat sink has come off or the fan underneath is not spinning.

After that look up in the wiki how to adjust the trimpot on the Pololu driver

It looks like it doesn't have enough power.

You could try to switch 2 stepperdrivers, but make sure to put them back the right way.

Look at the potmeters (tiny screws, only on 1 side) for an indication before you take them out.

The stepperdrivers are the small chips connected to your electronic board on the bottom.

The E stepperdriver is the one that is alone, like not in the row of 3.

If that doesn't make a difference, look in your UltiController.

If you have an UltiController, go to UltiController > Control > Motion.

I don't know from the top of my head what it is called, but what are the values that are connected to 'E' ?

It is very likely one of two things:

1) Bad stepper motor

2) Bad driver (aka polulu)

Swap something to see if the problem moves.

I would remove all filament, heat up the head to 180C (extruder won't move if temp is < 170C). Then move the extruder until it stops working. Figure out how long that took. Write it down.

Now turn off power, swap drivers, try again.

If it lasted much longer (forever) then it is a bad driver. Maybe you can adjust the current on it. If it lasted about the same amount of time, now change motors. Swap stepper motor with X or Y stepper. Repeat experiment.

Thanks for an answers. I swap drivers and the motors are not moving with bad driver (checked with x, y, and z axis).

what is that band around the extruder? It looks like the black lever is not all the way down in the slot...

Try turning the little potentiometer on the driver a tiny bit before ordering a new one.

Yes, I don't think it's related to the motor not turning properly, but Peggy is right - your extruder isn't closed properly. You need to squeeze the two prongs very tight against the body of the extruder, and slide the bolt on the lever all the way to the bottom before rotating it.
