    I am making a DIY Makelagelo art robot with a RAMPS-1.4 and the marlin firmware and I have ran into an issue with my stepper motors. I ran a test program and they worked fine, but when I upload a program or give it instructions via the usb cable, the stepper motor works fine, but the robot skips the stepper motor bits with no delay. I have modified the marlin configurations according to this website:

    Pretty sure it’s a firmware issue.
    My robot has no limit switches, no LCD, and no SD card support.
    I’m pretty much a beginner with Arduino, and I have no idea what’s going on in my Arduino’s brain. any help appreciated. Thank you.
