Voltage Measurement Locations
Depending which stepper motor chip voltage you want to read, you will need to
position your multimeter in different positions of the board. You will need to place a
small screwdriver with one end of the multimeter clipped onto it on the small screw
head labelled TP – and another end of the multimeter will need to be set to ground
on the board.
TP X will measure the voltage for the X axis.
TP Y will measure the voltage for the Y axis.
TP Z will measure the voltage for the Z axis.
TP E1, TP E2 and TP E3 will measure the voltage for print jets 1, 2 and 3.
