That drive is currently misplaced. I was hoping to find a download, but haven't found one yet.

I believe this is all you need. See the attached files

Thank you,
That was the ticket! The thing is moving in three directions. Now for limits, spindle control and 2010 screenset tuning.

Wall mount looks very nice.

Every time I look at that stupid pink USB stick, this is all I can think of:

Well, with all three of us on the centroid train now I hope it's a good setup!

Happy new year gents.

Guys I took PZ's advice and started a new thread so not to hijack Jake's thread.
Here is the link: https://www.hobby-machinist.com/thr...ontroller-conversion-to-centroid-acorn.65196/

I'll post my progress there.
Regards,

Below are a bunch of my PNCconf configuration files for Linux CNC and the Mesa 7i76e. Perhaps it can help Mega set up his, or help someone else. I figured I'd better do this before I started rewiring for the Acorn Centroid.
Cheers,

Jake

Thank you for the wiring and screenshots! I am still trying to move forward w Mach... currently I the nMotion board is seeing my limit and direction switches, but those values are not being passed to Mach3. I think I know what pins to use, but what port should I be mapping to?
