Xylotex 4 Axis Drive Box with PacSci 116 oz.in. Stepper Motors


Front View

The drive box (like the one above) comes with color coded 6' motor cables terminated with the connectors that plug directly in to the PacSci motors.

The Four 116 oz.in. Pacifc Scientific stepper motors will be like the three shown above, except they will be DOUBLE SHAFT. These motors are RFE (removed from equipment), so they are used, but they still run fine. They will work well on a Sherline size machine.
Back View Also included are the 110VAC Power Cord and a 3' Parallel port cable

$435.00 Complete, Ready-To-Run, Plug-&-Play Drive Box (available while PacSci motor stock lasts)

You will need:
1) a PC running a CAM program like TurboCNC or Mach2. These programs take the output of CAD programs (G-code files) and generate the required STEP and DIR signals out the parallel port for the box to use. These programs are configuarable to allow proper setting of the STEP and DIR requirements

2) The Xylotex 4 axis drive box and motors. The box requires 120VAC, 60Hz . The box can optionally be factory set up to run off of 220VAC.

4) Your CNC Ready machine (Sherline/Taig/Router/Retrofit...)

Important software consideration:

The drive box requires the STEP pin on the DB25 connector to have the follwoing STEP and DIR pinout:

  • STEP X - Pin 2
  • DIR X - Pin 3
  • STEP Y - Pin 4
  • DIR Y - Pin 5
  • STEP Z - Pin 6
  • DIR Z - Pin 7
  • STEP A - Pin 8
  • DIR A - Pin 9

The STEP input must be an ACTIVE HIGH (+) signal. The DIR line must be stable 200nS (nanoseconds) BEFORE and AFTER the rising edge of the STEP line. The STEP signal should be high for a minimum of 2uS (microseconds).

The drive box plays NO role in home/limit/stop switches, or spindle/coolant output. To see a possible method of connecting switches to a drive board, look at the top of this PAGE..



Note: Although the drive has signal line filtering and buffering, some spindle motors can make excessive electrical "noise" (EMI - Electromagnetic Interference). This should be reduce at the source (the spindle).
