    I have the x velocity max set to 65,000 mm/min and the G0 command does move the tool at this speed.

    When I enter g1 f20000 x300 command the tool moves at 39.02 mm/min
    While g1 f200000 x300 gets a speed of 39.02 mm/min
    and g1 f2000 x300 gets a speed of 39.02 mm/min

    In the past I have been able to use g1 commands and they worked. On the Z axis the g1 command works with the feedrate limiting the speed. Why does it no longer work on my X axis?

    Odd behavior indeed.
    What Gcode sender you use?

    Please run $$ report and copy all results to a cloud drive, post the URL here.

    That will provide a good basis for understanding your setup.

    Im using Coolterm. Ive also tried typing in the G1 code manually, which may be seen identically to sending a text file as far as the TinyG is concerned.

    I will post the $$ file tomorrow.

    Quick thought (it’s late)

    I think $xfr=800 is limiting in X , not $xvm

    Give it a try

    cmcgrath5035 you are a genius! That was my hold up. I wouldn’t of thought to try that with such an odly low and specific velocity limit

    Thanks
