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 mechanical movement

that motors will skip steps (this means that when a motor is driven it wants to turn but the forces on it are too

great and it returns to its original position). When this happens it could have several causes. Check for mechanical

stiffness and add a bit of lubricant to the threaded rod and the smooth rods. If this does not help and a motor

keeps skipping steps you can raise the calibration voltage for that particular motor to 0.55V.

Now we can attempt to control the printer with Repetier. Move the HEATED BED PCB into the middle of the printer

by hand and make sure the extruder arm is at about 20 cm (7.87") from the heated bed.

Click this button in the Repetier software:
