The PMDX-134 is a mother board for interfacing Gecko stepper drivers with CNC controls. 

Features of the PMDX-134

  • Simplifies system wiring and makes most connections pluggable.
  • Mates directly with up to 4 each G201X or 4 each G203V Gecko drivers by plugging onto terminal strip pins of the drives
  • Future Gecko stepper drivers that use Ground as COM (common) for Step and Direction may also be compatible.
  • Allows unobstructed access to Gecko adjustment potentiometers and DIP switches
  • Includes 2 standoffs for mounting the PMDX-134 at the correct height
  • Does NOT support the G320 and G340 servo drivers or older G201, G202, G210, and G212 stepper motor drivers.
  • Can connect directly to a PC parallel port using PMDX-DB25Ribbon and PMDX-DB25MtoM cables
  • Can connect to PMDX-125 or PMDX-126 using a PMDX-HDR26Ribbon or PMDX-HDR26Ribbon-18 cable.
  • Can connect to other breakout boards with compatible parallel port ribbon header connectors.
  • Can connect to the SmoothStepper or other pulse generators with parallel port style ribbon header connectors.
  • Motor connections are made by re-using the pluggable terminal strips supplied with the Gecko drivers.

Note: The step and direction signals used to run this board as a real time CNC device require precise timing. These signals are normally provided by a personal computer motherboard with an onboard parallel port, a parallel port interface card plugged into a motherboard with ISA, PCI, or PCI-Express slots, or by an external device such as the SmoothStepper. You cannot use a USB to printer adapter because it will alter critical timing of CNC control signals. Laptop computers, even those with parallel port interfaces, are not recommended as CNC control computers due to design features that can alter critical timing. If you must use a laptop be prepared to deal with these design issues and/or plan on using an external pulse generating device such as the SmoothStepper.
