Description

The PBX-USB is a USB interfaced CNC controller that was developed specifically to work with the CNC USB Motion Controller Software from link titlewww.planet-cnc.com www.planet-cnc.com. This Interface sports 4x 10 pin PBX-Header Connections for interfacing to our existing stepper motor drivers. It has an additional header for direct connection to our RBX-1 3 channel relay board. This software/hardware combination can be further expanded with jog key inputs and an I2C bus for nearly unlimited additional I/O. This will allow the development of jog pendants, digital readouts, and input/output cards for a variety of purposes. The software runs on Windows and replaces Mach3 or EMC2. It can even be run through a virtual machine on a Mac or Linux host.
