With regular GRBL we expect to get a line like the following:
Please perform this test and report back. The Pn:PXY show here that both limit switches are triggered as far as the controller is concerned.
If you’re inclined to perform the next tests, repeat the question mark test while holding one of the Limit Switches and report that result here… then repeat this a third time while holding the other limit switch.
Please copy and paste the results into a reply here for confirmation.
Looking forward to seeing the results.
