4-Axis Mach3 USB Motion Controller Interface Board, 100 kHz

This 4-axis USB motion controller interface board connects stepper and servo motor drives to Mach3 software with step-pulse frequencies up to 100 kHz. It provides dedicated connections for limit switches, emergency stop buttons, automated tool probes, and spindle control. It is an ideal control solution for makers, educators, and hobbyists building custom CNC machines and 3D printers.

Multi-axis motion and pulse control

The board provides 4-axis linkage support to connect up to four stepper or servo motor drives with a maximum step-pulse frequency of 100 kHz. It also supports connection to an electronic handwheel for manual control.

Versatile inputs and spindle regulation

Four general-purpose inputs accommodate limit switches, emergency stop switches, probe switches, and homing inputs. A 0-10V analogue output port allows Mach3 software to regulate spindle motor speed.

Isolated relay outputs and power requirements

Four general-purpose isolated relay drive outputs allow automated control over spindle start, forward and reverse rotation, and pumps. An external 24V DC power supply is required to isolate the USB connection from external ports for system stability, with an on-board LED indicating connection status.
