Unity-M2 Controller

Unity Controller customized for use with bench-top mill conversions using a higher amp Z driver with NEMA34 motor options and the replacement of the fifth driver by two extra relays.

  • Expandable to your needs, versatile, and flexible.
  • Can be used for 2, 3, or 4 axis systems.
  • Get it with or without motors
  • Motors (if purchased) are pre-wired with 6 Feet of 5-Conductor 22 Gauge Motor Wire and XLR connectors

Have A Look Inside:

  • 40Volt (110VAC Input) Linear Power Supply for the fastest motor operation
  • Professionally wired, installed, mounted and tested electronics
  • 4 Drivers, Breakout Board, IDC cables, and wired connector ports
  • Full Enclosure with Power switch, fan, and fuses
  • Modular and organized

Driver System:

  • 3x 5.6Amp MondoStep Bipolar Drivers (X, Y, and A axis)
  • 1x 7.8Amp MondoStep BiPolar Driver (Z axis)

Breakout Board:

The PBX-MX is an isolated parallel port breakout board for use with software such as LinuxCNC or Mach3.

Integrated back panel includes:

  • Connections for up to 4 motors
  • Connector for limit switches
  • Connector for E-Stop
  • Earth ground connection for improved EMI protection
  • Auxilary 5v logic output that can drive an accessory like the Powerswitch Tail
  • IEC power connections for the primary power and the router control relay
  • Built in PWM to 0-10VDC analog signal interface for spindle speed control to a VFD or SuperPID.
  • PBX-MX Isolated Parallel Port breakout board
  • Two AC inputs
  • Color coded

Pin-out

We recommend using LinuxCNC's coolant mist and flood for controlling Relays 1 & 2. This would provide M7 and M8 commands and on-screen checkboxes for control.

Note: These relays do not provide power, they simply open/close circuits.
