Maybe I'm missing something, or its been asked already, Why doesn't the new Black Box X32 have 4 end stop inputs? I have other machines that use belts and they are very easy to knock out of square. Having a end stop in each Y motor makes it really easy to re-square the machine by homing. Can one of the other inputs be used as a 4th endstop?
Yes, and GrblHAL can also be configured to slave limits off each other (share A and Z on the Z input for example) - we will be posting details in due time
