Ok that is fine for the frequency as I was wanting to know if you had selected the external controller and you have.
Place this xml in the Mach3 folder and using the laoder open it and see how you get on. I have not changed any ports or pins from that of the original one so not sure if they are correct or not but see how you go.

OK, I cloned it and used Mach Loader. Initial error was for different s/n, OK. Now it gives me "Spindle-axis Step Port = 0. Valid values are 1 and 2."
"Spindle-axis Dir Port = 0. Valid pin values are 1,23,4,5,6,7,8,9,14,16, and 17" errors.
X,Y,Z,A are step port 1 dir port 1 with 2-9 pins on the axes, and spindle enabled with step pin 14, others zero.
X,Y,Z,A homes are port 1, 10-13, respectively.
EStop is port 1 pin 15.
Outputs port 1 pin 17, port 1 pin 1.
Charge pump port 1 pin 16.
I applied those and it gives me the original spindle errors. I believe I'm closer to running, though! What should the inputs be for a relay-based router
as the spindle? It's not set up yet, physically.
Thanks much for the help, by the way, Hood!
