my Y-Axis is powered and wired to a external stepper driver to the C3D LaserBoard.
- Now I have another (a second) external stepper driver left and I want to know if I should go for the X-Axis or the Z-Axis?
I ask this, because the Z-Axis (movable bed) weights 5kg and is attached on 4 sides to a trapezoid thread rod.
- Is it more clever to put the external stepper with the motor to the “heavy lifting Z-Axis” or doesn’t it even matter at all?
- And if I connect a stepper motor directly to the board, do I have to use the green connectors behind/infront of the 4-pin connector?
Thanks for helping
