This is a kit to build the control system for a CNC milling machine. All parts were pulled off a working machine built in 2003 for hobby use, and in good condition.
Included in this package:

Centroid M400 CNC Motion Controller with Linux V2.61 SSD.
  • All buttons work, cables are in good condition. 
  • Fiber optic cables have not been kinked. 
  • - Built in conversational programming cycles
  • - Built in part/tool probing cycles
  • - Built in Tool changing capabilities
Centroid M400 Brushless 4-axis AC Servo4 Drive System.
  • Used for AC Motors
  • Plugs are available if needed, they are currently attached to the motor cables.

Centroid PLCIO2 unit for M400 and T400 CNC machine I/O

  • The PLCIO2 is a general-purpose PLC unit which expanded the I/O protocol to support 35 inputs, 39 outputs and a 12-bit analog spindle speed output.
  • Used in M400, T400, and some M39 and T39 controls, 2002-present.
  • Inputs may be 5V, 12V or 24V, either current-sourcing or current-sinking. They are configurable in banks of four: different banks on the same PLCIO2 may operate at different voltages and/or with differing current flow. Input SIP resistors must be installed to match the input voltage on each bank of four inputs.
  • Input power must be externally supplied.
  • Logic power is supplied by an external switching power supply, providing +5, +12 and -12 VDC to header H1.
  • Of the 39 outputs, 22 drive on-board relays rated up to 10A and 250V; the remaining 17 are 5V solid-state outputs which require external relays or SSRs.
  • The analog spindle speed output can be configured for either 0-5V or 0-10V.
  • There is no on-board provision for bipolar analog output. You must supply an external DPDT relay to switch the analog polarity if your spindle drive requires it.
