    I looked in your other thread on this same problem

    Here is something for you to try, I have 2 things that may be causing you problem

    Can you run through the program without the router running you could easily have a noise problem for that router that is causing a problem with the Z axes stepper motor

    The other problem is you should not be programing using a G91.1 as if there is any error this will make it worse

    Thanks but in in the process of reinstalling MACH3. If the new copy of Mach doesn’t fix it I’ll be back searching for solutions.

    The G91.1 is fine.
    Mactec doesn't know what he's talking about.

    Really I said it was something to try, G91.1 this is not normally use for any type of programing and was only developed for users that could not understand how to setup there machines, it is totally not needed if the control is setup correctly

    If you can prove other wise we are all listening

    G90.1 & G91.1 Set IJK Arc Mode
    Interpretation of the IJK values in G02 and G03 codes can be in one of two distance modes: absolute or incremental.
    To go into absolute IJ mode, program G90.1. In absolute distance mode, IJK numbers represent absolute positions in terms of the currently active coordinate system.
    To go into incremental IJ mode, program G91.1. In incremental distance mode, IJK numbers usually represent increments from the current controlled point.
    Incorrect settings of this mode will generally result in large incorrectly oriented arcs in the toolpath display.

    Your Mach3 was running ok you proved that by using other programs

    Like I said run the program with the Router turned off

    On the contrary, this makes sure there won't be any issues.
    You've been trying to tell people for years not to use G91.1, when in reality, it prevents users from having errors.

    It does not prevent anything if the control is setup correct

    It's only a simple I &J setting in Mach3 that takes care of any problems anyone may ever have

    If this is set correct in General Config. there is no need for it to be in the program it serves no purpose

    Z axis drive is stalling is the most likely the problem when using an Open Loop feedback system.
