 Includes an esp32, microUSB version.

These work great on a ZenXY, with one exception. The new fluidnc does not allow for negative endstop travel so you will need to manually trim the endstop flags on the ZenXY to adjust your exact home position. One that is done, everything works as expected.

I do have two of the older GRBLESP32 versions that do allow for the negative movement. Send a note if you want those substituted in your order instead of this version.
