Hoping you can help me out. We built a Cbd plasma machine and so far so good. Because of the size of the machine being 1,5m x 2 m we are running 2 y axis motors. Everything is working fine but every now and then the y axis gets stuck and it destroys what ever part we are running. Also we cannot make near perfect circles. It is usually off by 0.5 to 1 mm off and they look like geoids and not circles.
Any suggestions on what we can try and trouble shoot?
We are running and arduino to run the machine.
