    Are they better for you to read now or do I need to scale them up more?
    Sorry, but they look the same to me. Still unreadable.

    But if you wanted to here is the code. Note that your drive gear diameter may be 11mm, but they are accounting for how far the teeth sink into the filament.

    <geometry type="cartesian">


    <axis id="a" length="100000" maxfeedrate="1600" stepspermm="96.275201870333662468889989185642" endstops="none"/> <!-- stepspermm is incoming filament length, see comment at bottom for explanation -->
    <axis id="b" length="100000" maxfeedrate="1600" stepspermm="96.275201870333662468889989185642" endstops="none"/> <!-- stepspermm is incoming filament length, see comment at bottom for explanation -->

    <!-- explanation of steps per mm:
    Steps/mm is calculated by dividing the 'drive gear steps per revolution' (in this case, equal to motor_steps) by the 'drive gear circumference' (drive gear diameter = 10.58)
    So we get: 3200/(PI*10.58) = 96.275...
    -->
