It has a Mitsubishi A800 drive. (I can get the specs tomorrow) It came with 3 900+ page books. I know it receives forward and reverse signals separately. I I'm pretty sure it's PWM, but to me honest, I don't know. Sadly, I didn't build it or configure it. Coming in after someone else kinda stinks.

Moved to "PlasmaC" section.

Thank you.

The original thread was getting way long, with a lot of info spread out.
Pleas pay particular attention to the hal_gpio stuff, there is a basic 3 axis mill config that works. If you get any errors when thrying to use hal_gpio, unless the error log states "no permission" the issue is a permission error (which should not happen), otherwise it is related to the GPIO pins selected or somethng else. Mostly this occurs when a user attempts to use the SPI allocated pins without disabling the SPI interface.
What I suggest to the RPi users is to bookmark the Index thread forum.linuxcnc.org/38-general-linuxcnc-q...l-images-only#325007 for later reference . 

The major difference re GRBL & Linuxcnc is that Linuxcnc (what runs on the PC) is interprets the gcode and works out the timing & responds to realtime events.

With GRBL the PC sends gcode to the GRBL controller and that interprets the gcode.

There is no option (and so far it does that like it will ever be an option) to send gcode to an external controller.

UNITS = INCH # issue a G20 at load
DEFAULT_UNITS = INCH # same as G20

Remove the comments from those two lines.

Talking about having to drop this menu down and change every time. I thought i changed everything in the ini related to units (attached).
