You can test if the cable is shorted by checking the continuity between the white and any of the two black wires, it should be open. The reason the Mightyboard is feeding Vref a voltage to the BotSteps is to allow it to adjust the hold current on the stepper motors.

The connector on the heated build platform can sometimes be misaligned and cause a connection with bad contact, leading to resistance and miightyboard heat production. It is recommended to do a good job of heat dissipation, and the working current is about 0. The key differences are as follows: So while the extruder is heating up, the steppers can be drawing less power. It mifhtyboard a plain maze of copper traces as heater elements. The reason the Mightyboard is feeding Vref a voltage to the BotSteps is to allow it to adjust the hold current on the stepper motors.
