Setting up soft limits in UCCNC .. "Logic"

[ngwagwa]

So are we saying that the ONLY reason for softlimits is to prevent the machine traversing beyond the home switches and crashing into endstops ( and I guess killing the traverse if we try to go beyond the positive limit, regardless of whether switches are fitted there) . in which case it seems to make sense to have a soft limit of zero and maybe an arbitrary back-off of say 5 , (and I guess that wound be +5 to bring it back within the working area)

So then I guess that I choose an offset in my G code routine to bring the tool to a new start position on my workpiece , Is that so ?

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.
