Setting up soft limits in UCCNC .. "Logic"

[JAZZCNC]

So really it is only if I have placed my job wrongly and that the toolpath will stray outside the envelope that a soft limits alarm should arise .
Are you saying that it should arise prior to hitting the start button . or will it only arise when the work zero position is defined .

Ok lets say you define your WORK ZERO in X half way up the work envelope (or put another way 200 in MACHINE coordinates.) And you defined the X ZERO point in CAD to be bottom left corner of the part and the part is 400mm long in X. When you load the code and it does it's Pre-check it should warn you, I don't think it does when you push cycle start the control should warn you before then. (In UCCNC this feature might need turning on in the settings, I think it's called Softlimits pre check)

It's easy to test just set WORK ZERO for X & Y up the top so the part falls outside the cutting area and set you Z axis at the top of travel so no damage can be done if it it doesn't work but you'll know straight away because it shouldn't work at all in which case hit the stop button.
