    As soon as you need limits your job is toast.
    Plan ahead and ensure that your job fits in the machining envelope and that you have your work offset or your zero set such that the job which will fit the envelope is within the envelope,

    You think that's too expensive? You're not a Model Engineer are you? :D

    Sorry Nick don't agree. Softlimits work good because they won't allow code to run unless it fits within the machines cutting range. They also stop you accidently running into the hard limits which can be pain.
    The only thing is that the machine must be homed first for them to work properly.

    ECCO: First Slow zones don't work so forget them.

    Setting the Soft limits is easy. Set Soft Max for X & Y to +19 & 7.375 and Soft Min =0. For Z axis Soft Max =0 Soft Min -13.500

    Remember you must always Home when first starting machine or after resetting for soft limits to work correctly.

    I struggle with the concept of unknowingly creating and running a job that doesn't fit within a machine's envelope but I can imagine that with the right approach that should be possible ;-)

    Yes I understand and agree to point but there's more to it than that. The fact you can't run into the limits is worth the trouble of the 1min it takes to setup. Very useful on small machine that can run from one side to other in blink of eye while jogging.

    Ok gentlemen the soft limits are now functioning as they should. X & Y movements are declared in Soft Max and the Z negative movement is entered in Soft Min. Even slow limits work. Many thanks for your assistance. Regards ECCO.

    If your meaning Slow Zone then it doesn't work like you probably think. It's only used when jogging NOT when homing. So when approaching the limits it will slow down gradual at the distance entered.

    When homing the Speed% is used which is % of the velocity set in motor tuning for that axis but will travel at this speed over the full distance each axis has to move.

    JAZZCNC thanks for the advice. Can we presume that when running a program that the cycle would not exceed the soft limit envelope? ECCO.

    When soft limits are turned ON then Mach will give a Soft limits warning when you press cycle start if out of limit range.
