RE: [CAD_CAM_EDM_DRO] Help implementing spindle & coolent on/off

Hi,

I'm in the process of testing a converter board I have built to allow
Master5 to drive the Controller box that comes standard with the Taig CNC
Mill. The standard controller uses a phase drive input. It has no limit
switch or relay driver capability.

The board I'm testing allows a single port to control 4 step/dir axis, 4
limit switches (with the option to sync the limit switch with a particular
phase), emergency stop input, drive enable input and the capability to drive
four relays.

Each of the function mentioned above are controlled by 4 PIC16F628
microcontrollers, one for each axis. The driver for the relays are provided
by a single ULN2003A chip.

Since your using Gecko's, the PMDX-120 seems like a reasonable way to go.
Although I haven't used one, only seen the site at
http://www.pmdx.com/PMDX-120/index.html

Cheers,

Peter Homann
