    Good call Clive!
    I rarely think of the basic machine set up being at fault! :D
    You think that's too expensive? You're not a Model Engineer are you? :D

    I got it figured out! It was an extra decimal point. i.e step per was set 2000.xxx instead of 200.xxx
    I guess, I assumed the step per start at 1600 and goes up.

    Appreciate your help, everyone!

    Now the step per is resolved, I need help to figure out why everything except square, rectangle, and straight lines come up deformed.

    The shapes below were supposed to be 20mm circle, and 20x20x20mm triangle.

    Could be missing steps ie. acceleration too high or voltage to the steppers too low. Or even excessive backlash. Or couplings loose on the motors.

    Glad you got the steps per right now.

    How to sort them out?
    The only things I'm sure is not the issue, are the voltage to steppers and coupling, the seems/feel tight/fine.

    Well you was sure the steps were fine before. Post a pic. of the machine also what drives and what is the voltage supplying them. What is the acceleration settings in Mach.

    Have you measured if the actual distance is the same for X100 and Y100

    We don't have crystal balls to see these things.
