About this product
A CNC interface card built around the TB6560 stepper driver for controlling up to four axes of 2-phase and 4-phase motors in the 42, 57 and 86 frame sizes. It connects to a PC through a standard parallel port and works with Mach3, MACH2 and KCAM4 software. It also includes optocoupler-isolated inputs, spindle relay control and microstep selection.

Frequently asked questions
Which software can control this CNC interface card?
The listing states it works with Mach3, MACH2 and KCAM4 series software through the standard parallel port. Set the motor, step and spindle parameters in the software to match your machine.
Can it drive NEMA 17 motors?
The listing specifies 42, 57 and 86 frame steppers, which correspond to NEMA 17, NEMA 23 and NEMA 34. The listing also says the motor phase current should be below 3 A, and the driver output must stay within its 3.5 A peak rating.
