The controller board of the printer has 4 motor drivers, these are the 4 little PCBs that sit on top of the main board.

These drivers control the current that flows through each motor. To do that correctly each of them needs to be calibrated. Take your multimeter and a

Adjust the little trimmer on the driver with the ceramic screwdriver until you measure 0.425V.

Repeat this process for the other 3 motor drivers. In the following steps we will test all the motors of the printer, it is possible due to stiff me

First strip the end of the cable so you have 15 cm (5.9") of free wire. Be careful not to cut too deep while you are stripping the cable.

Loop the wire through the first tie wrap as shown in the picture.

Use the clamp-on filter as shown in the pictures below.

Now loop the wire through the second tie-strip.
