Core 2 with GRBL 13.2 Module

[Revilo_oli]

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
