Motors are not working

[mere 0]

Hi,

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?

Thanks,

Zoltan

Really simple question, are the motor drivers in place?

Look at this photo:

http://wiki.ultimaker.com/File:El1.5.4-PCB.jpg

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:

http://wiki.ultimaker.com/Electronics_build_guide

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.

- Do the motors get warm ?

- Have you plugged in the motor wire in the motherboard ?

Looking at the board, I don't have any motor drivers mounted on them. They are not in the box, either, they are missing from my batch.

Seems they sent you a motherboard that hasnt been tested. The tested motherboards are always supplied with stepper motors. Contact support, they can help you further.
