    How do you know it moves in inches? Does the X move in inches as well?

    You need to give more info about the settings on your machine etc.

    If Z is moving around 25 times further than required then the motor tuning for the Z axis is probably incorrect, it is most likely doing exactly what it has been told to do.

    Make sure tuning is correct may be totally different to X & Y and be sure to save axis settings every time changes are made, you solved the motor tuning problem with auto calibration in this or previous thread, how are you measuring that movement accurately with much smaller Z axis movement any errors may be larger.

    What setting do you mean I'm new to this

    The motor steps per unit in motor tuning.

    I done the automatic motor configuration in the setting menu measured it movement it was correct.
    When I toggle the z and y with the arow keys it will work in mm I can be seen that the movment matchs the fro but when z is moved the movement in the dro and a axis will move in inchs

    The only way that can happen is if you've got your motor tuning wrong.
    Motor tuning units are set for all axes at once so you can't have a mix.
    If tuning units are set to mm and X and Y work fine you will get really close if you take the number for "steps per" currently set for Z and multiply it by 25.4, Mach3 can't tell when you instruct it to do stupid things, it simply does what it's told.

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

    When I stated in your previous thread to check wiring you responded I was definitely wrong then that you had found the broken wire.
    When I stated the code was wrong and would not run in a different thread, you replied I was wrong and later PM'd me to get the edit to correct that code.
    Again I try all axis are using same measurement scales they cannot do otherwise, therefore your tuning steps per unit are incorrect they are for mm's if axis is moving in mm and for Inches or out by a factor of 2540% if axis is moving in inches instead of mm.
    There is no alternative computers just do what they are told, you put rubbish in you will only get rubbish out its the way it is.

    I started changing the motor tuning rather than the running in the setting.
    But when I run the code after setting zero the z just go's down past the materal down to the bed maybe I'm not setting the zero right.

    I'm very thankful for all your help don't think I'm not the pm was a personal thank you

    Can you show your working for the maths that give you this result? ;-)
