    • Control Stepper Motor with Core2 and GRBL 13.2

      Hello,
      I'm using the Core2 controller and the GRBL 13.2 module. I want to drive two stepper motors continually at a slow speed. The motors are attached to rollers, so they should be continuously rolling.

      The motor I purchased is a Nema 17 bipolar from here: https://www.ebay.com.au/itm/175580114720

      I have the motor turning using the example Arduino code, but the torque is very low; we can twist the axel easily.
      What could be causing the toque to be so low? Have I specced the motor incorrectly, or do I need a different driver?
      Thanks
