    I am building an ACRO 1010 using the NEMA 17 steppers and the CNC xPRO V4 Controller Stepper Driver board
    Was checking for proper commanded movement via GRBL and Lightburn software.

    After completing a few homing cycles of 100mm each time, I noticed that the Y1 motor was very warm to hot. Y2 was luke warm ans well as the X motor.
    Do I have the current too high? Y axis moves nice and smooth so I know it is not a binding issue.

    Thanks

    Never mind, figured it out.
    Had to re-adjust the current pots. Had turned em down when I should have been turning them up.
