- Ceramic Screw Driver
- 2mm Hex Driver
Start by removing the 4 screws on the etray Cover with the 2mm Hex Driver.
Move the etray cover to the side, and locate the stepper drivers inside the etray as shown in the picture.
NOTE: The stepper drivers from front to rear are X, Y0, Z, E0 and Y1.
Grab your multimeter and turn it on to 2V setting.
With the machine powered on, put the black probe on a ground terminal (shown in picture), then insert the red tip of the probe into the lowest gold hole of the three, located on the stepper driver to measure the voltage. Since these are metal, be careful of the placement as you may short components.
The voltages should read:
X, Y1, Y2, Z : .750 +-.003v
E0 : 1.000 +-.003v
Insert the ceramic screwdriver into the hole located above the 3 gold holes and make any adjustments necessary.
