    Totally agree with the low tooth contact area on the top pulley.

    Would another idler wheel below the drive pulley be sufficient.... ... Say 180 degree + contact area.

    Also I'm not familiar with the stepper drive power system you mentioned. I'm looking AT Chinese Hss86 closed loop DRIVES. To drive a nema 35.
    If its a way to power them, is there a handy video available. ☺

    Bear in mind the machine will be cutting ply, plastic sheet, wood and maybe a bit of aluminium.
