Setting up soft limits in UCCNC .. "Logic"

[John11668]

Correct re purpose of softlimits ie prevents crashes at end of travel.

Whatever back off you set you don't need to alter the gcode as Zero is still zero. So to clarify on my machine with a back off of minus 5mm after machine has been homed the DRO will display -5mm when displaying machine co-ordinates.

But doesnt a backoff of -5 take you beyond the home limit presuming you are homing in negative direction from an x positive position on the table .??

As I said earlier make sure you have the right direction for the back off - my home is far right so moves postive in X to get home, therefore I back off negative.Big noise and you got it wrong!
