Hello again folks. I’ve recently upgraded to Marlin 1.1 and a new pica board (Thanks Marty!). Everything seems to work great, except that the auto homing does not appear to raise the apparatus high enough before moving towards the min X endstop. This means there is not enough space for the z probe to lower, and the printer jams. There is a setting in marlin for
Z_CLEARANCE_DEPLOY_PROBE but that appears to only apply to what Marty has created, which happens after X and Y have been zeroed.
EDIT: Solution found here
