    So I finally got every thing connected on the tinyg. I have motor3 and motor 4 on the y-axis. I set
    $3ma and $4ma to = 1. I can turn the motors flex coupling and every thing turns find by hand.
    But when I connect to universal G code sender and hit the y+/- the motor 4 turns fine. But appears
    to be no movement on the motor 3.

    I disconnect the lead screw on both sides for testing.

    So just the motor is connected to the flex coupling. I up the step to 5 in on the universal gcode sender to
    see the motor rotations better.

    If I click the +/- I see motor 3 move several turns. But motor 4 moves only a degree or 2. So I thought I
    might had a bad motor. So I changed the motors for 3 and 4. But only to find the motor connect to motor
    3 output on ting moves only a few degrees.

    The trim pots are set between 4 and 8. I moved them motor 4 slightly to left or right with no change.

    Any suggestions? Setting?

    Thanks

    Problem fixed… I discovered the $3tr=1.25 was the same on $1tr and $2tr. But on $4tr it was 3.60. Changing it to 1.25 and reconnect the leadscrews etc all works.

    Good, you are in business.

    I was going to suggest your provide a parameter list ($$ report) on a cloud drive with URL; that frequently reveals info and provides a lot of info about your setup.

    Good luck with your machine.
