Motors are not working

Recommended Posts


I've just assembled my Ultimaker(Batch 6) and I can't get any of the motors(x,y,z,extruder) working.

When I connect it to my computer via USB, the main fan starts up. I switch the power on and the fan spins up even more.

I can connect to it in replicatorG, I can heat up the extruder head and switch the extruder fan on and off.

When I try to test the stepper motors, nothing happens.

Any ideas what I might be missing?

Really simple question, are the motor drivers in place?

Look at this photo:


On the right there are 4 motor drivers, they should be placed exactly as in the photo. Make sure they are not the wrong way around.

Also, maybe the step drivers are tuned down all the way, check:


especially the part about tuning the step drivers. While they tried to tune the drivers correctly, they might have shifted during transport, or where tuned incorrectly.

The Ultimaker team is improving this in their production step, new kits shipping this week should have better calibrated drivers then the drivers shipped in older kits.
