Hello there,
I have recently got myself a CNC machine and run it under Mach3
There are no Home switches on the machine, but i have set up the limits on the workbench in Config/Homing/ Limits
It works fine when I activate the Soft Limit Switch in Mach3, but i do not seem to be able to make it work when am running a job in the machine,
Then the Soft Limits do not work at all,
Am i missing something here ?
Any help would be much appreciated

You need to home your machine for softlimits to work. That does not mean you need home switches although that is obviously preferable.
If you dont have home switches you can jog X and Y fully negative and Z fully positive then press RefAll button. That will set the machine coords to zero and your soft limits will now work as Mach knows where it is.
You will however have to do that each time you start Mach and you must be able to repeat that position accurately before you press the RefAll button or the softlimits will be worthless.
