I'm have trouble finding the Test points for testing the Controller prior to installing the stepper motor control chips

I had replied to your email, but I'll post this here in case anyone else is having trouble spotting them.

I have marked the testpoints with arrows in this diagram:


TP1 for X Axis,
TP2 for Y Axis
TP3 for Z Axis
5V for testing 5V rail.

Test with a multimeter between the test point and the ground screw terminals.
