Yes I know this, I am asking if the GTM32 Pro has accommodating pins for Z-Min to enable a probe.

I can see from product pictures that the GMT32 Pro is almost identical to the GMT32. With the exception that the Pro has custom connectors.

Hi all,
last night I constructed my new Rostock 301. However it doesn't come with a z-probe for bed leveling. I would like to add one. However I am confused as to where it would be wired to on the GTM32 board.

Any further advice on where in the firmware to modify to enabling would also be welcome ...
