I checked the wires and they seemed fins so i put it back together again and suddenly the extruder was working again. One small problem.. the motor was extruding when it should be retracting and retracting when it should be extruding. Later I found out that after checking the wires I put them back together just like the other motors for the Z, X and Y axis.. the problem is that the extruder motor wires connect to the board differently.

Anyway, its working again but I still don't have any idea what caused the the motors to move like they where.


Thanks anyway for the help,

but when slicing with slicer it is working the way it should.

Strangely enough the extruder motor is now working again but only it extrudes when it should be retracting and it retracts when it should be extruding.

Does anyone here have had this problem?

I'm trying to solve this problem for 2 days now and I have seen some screenshots of the repertier host, it seems with my printer the green graph is lower then some others are showing (is it correct the green graph shows voltages?)

I fixed the printerbed and the printer was working fine 95% of the time.

Could it be a part on the motherboard thats broken?

I switched the z axis chip with the extruder chip and now the zaxis works fine but the extruder motor is still not rotating. (I also changed and checked the voltages with a multimeter again)

I'm going to uninstall the repertierhost and driver for the printer and install it again to see if that helps. If anyone has some suggestions about how to solve this please let me know.

I checked the voltages

Extruder= 193 proper voltage should be 192

With the power turned off, unplug the extruder motor from the board (marked E) and swap it with another motor, like X.  Then click the X arrows in Repetier and see if the extruder turns.  If not, then there is something wrong with the motor.  If it turns properly, then there might be something wrong with the driver chip.  It might be as simple as adjusting the voltage, or the chip might be bad.



I swapped the Y axis motor with the Extruder motor and now the extruder motor is working as it should. So I guess its the chip then, should I buy a new chip or is there anything else I can try to make the printer work again?

So does the motor move freely with out the filament?

Ow sorry, no the same happens.. extruding about 3mm than retracting 3mm over and over again. (There is a video in the text file below the last reply)

Looks like your hotend is probably clogged. There is a pretty good set of instructions for cleaning your hotend on the Official wiki.

NOTE: Be very careful when tightening up the acrylic pieces or removing the hotend. The acrylic pieces WILL BREAK.

No the hotend works fine. I removed the filament from the extruder and the same thing happens. (New video below)

I am having a hard time seeing what is going on in the video. Can you use a sharpie or something to draw a line on the filament gear? That way we can see the movement.


Ok, Thanks for the reply,  I have drawn a line with a pencil and the video url is in the text file below (cant post a url at the moment)
