Hi i have my electronics all hooked up and i am building a MendelMax 1.5 or 2 i'm not sure.
I have the stepper motor driver connected to their position according to schematic diagram and the microsteppers jumper were installed. The scenario is this:
X and Y axis works fine. Z axis couldn't move with two motors connected at the same time. Loud buzzing and whining noise is heard only. When i take off one of the Z motor, it moves smoothly. The stepper motor driver i used here is A4988 red colour driver. I have changed to DRV8825 purple colour driver to test and they could turn smoothly but the driver turns incredibly hot.
The power supply i'm using is a 12V 30A power supply. Can anyone tell me what the problem is or teach me how to further troubleshoot to identify what problem it is?
Thanks.
