I am new to the world of cnc and have bought a J Cut 25s I want to convert it to run on Mach 3. I have replaced the BOB with a UG08 and UC300 from CNC 4 You to run from a Windows XP Laptop with a usb port. I have the rewiring part finished and installed Mach 3 and the drivers for the UC300 but I can't get the machine to move on any axis. I would really appreciate any help as i have tried everything I can think of

Thank you in advance.

Not familar with the UC300, but, do a search on it and you will find some posts about using that controller.
The posts were rather recent and some users have had problems wih it .

You may also want to try  the driver test for that laptop and see how well it will works with Mach.
