      Hi everyone,

      I'm currently working with a Core 2 v1.1 ESP32 and GRBL module 13.2, and I'm encountering an issue with my stepper motor setups. Here are the details of my configuration:

      Controller: Core 2 v1.1 ESP32
      GRBL Module: Version 13.2
      Power Supply: 12V, 3A
      Stepper Motor: normal Bondtech NEMA17 Pancake Stepper, 25mm
      Software: UI Flow
      Step Subdivision: 1/32 Step

      Issue:

      The stepper motor only functions correctly in the Z axis at normal (slow) rotation speeds.
      When attempting to use the X and Y axes, the motor does not work unless I increase the feed rates to 10x or higher.
      When i try to change the adress to 0x71 the module is not beeing recognised.

      Troubleshooting Done:

      I've tried changing the step subdivision and the power supply settings.
      I've tested this setup with 5 different GRBL modules, and the issue persists across all of them.

      Could this be a bug in the GRBL module? I'm wondering if anyone else has experienced similar issues or has any suggestions on what else I can try. Any help would be greatly appreciated!

      Thanks in advance for your quick responses!

        With some testing it was found that the core 2 was faulty and it had to be replaced
