Enable limits during homing UCCNC UB1
When homing the signals from the limit switches are not considered.
Is there a way to enable this?
Reason is I'm doing a upgrade of an old mill which has +/- limits separate from home switches (located some 1/3rd between limits). If the machine is on "wrong" side of home at start up, it can crash during homing procedure.
Ideally hitting a lim during homing should make the direction change to reach home signal.
I could solve this by using the lim as home, but thought I might ask for other solution first. Having home 1/3rd between limits makes homing faster with less transport.
Im using UCCNC with a UC300eth UB1.

That's an interesting issue. You'd think the machine would know which side it was on and move accordingly. ie: the shortest direction back to home without going near a limit switch.
I have no solution for you but I am updating to the 300 and uccnc soon too.
I'll have a good read through all the uccnc stuff tonight and see if there is anything mentioned for a resolution.

Thanks.
Before homing the machine has no clue as to where it is, at least not on such a system (steppers with encoders "hybrid servos". The direction for homing can be set, but that does solve the problem.

Threadlift of the week, I know but still; no input for a better solution enabling the lim sw during homing?
