hooked up the motors and they all ran except the motors wouldn't run at low feedrates they would just jimmy back and forth and when I would jog or run a short program the machine doesn't always run in the right direction, if I tell it to go in the - direction it might keep going in the plus direction but then it would go in the - direction there was no set pattern. using a laptop with +5v from the usb port and running cncpro. Any suggestions? Running Camtronics control stepper motors
