    I had another thread on a problem I've been having I nearly sure it now is the motor tunning.I have the native etc set for mm but It alway seems to go 40inchs rather than 40mm has anyone any details on how exactly to do it

    Motor tuning, whatever units it's set in, gets down to measuring travel and adjusting the units.
    Start with a 1mm move and adjust settings so it's near, then go to a 10mm move and adjust so it's near.
    After that try whatever distances you have good measuring equipment for, I use a DTI and guage blocks.
    Call your moves from the MDI tab,
    That's it,

    If you will not be swayed by logic or experience simply pick the idea you
    like best, but ask yourself why you sought advice in the first place and,
    for a simple life, perhaps consider not doing so in future

    Config - Select Native Units
    You will note from the pop up that this is for motor tuning and doesn't affect how G-Code is interpreted.

    Call a move, measure travel, adjust units, don't rely on automated motor tuning,

    Do you do it manually in the motor tunning drop down or do it in the setting move x 20 how far did x move

    I've never used the drop down motor tuning do-dad, I've always started manually from the steps per turn for the steppers, screw pitch etc. then measured some moves, starting small then getting bigger, adjusting the tuning figures to correct over/under size moves

    Mach3 has an auto calibration feature on settings page just install a recent version!

    I did play with the auto feature it wanted me afterwards to select a higher Kernel Speed

    It will do that, if you are trying to output more steps than it can fit in with the current set speed, the number of steps is restricted by the speed the kernel runs at.
