Hi Guys, I have an early Bridgeport Interact CNC milling machine, I converted it many years ago to use MACH3 and was working really well. I have been using the CS LABS IP/A motion controller. This stopped working so I sent it back to Poland to be inspected. They confirmed the device was faulty. After paying out large sums of cash, I received the repaired device back only to have the same fault. Now CS Labs support are no longer getting back to me.
What other motion controllers can I use. My Servo drives use a 10v signal, and I only need 3 axis.

A lot of drives have both 10-0-10 volt input called analogue and also TTL step and direction input you need to find or check the manual for the drives you have.
If the drives can take TTL(0-5V) then any mach3 breakout board can drive the machine.
Sometimes you need to tell the drive the input type but some detect is automatically.

Have a look at CNC drive motion controllers. I have the uc100 and the eth400 and have not had issues with either. you can use the uccnc software or there is a plugin for mach3. you can ask questions on the forum to make sure it will do what you want.

Are these the old DC Servos? Nowadays, it is just better to go with AC servos or closed-loop Steppers. Those motors are high-maintenance and probably old, with a lot of wear. Get something that is brushless, uses new technology, and is easy to connect to.
