For my MESA 7i92 I have this set up for sharing limit switches.
The Home and Minus Limit switch for the X axis are shared.
net min-home-x => axis.0.home-sw-in
net min-home-x => axis.0.neg-lim-sw-in
And the Positive Limits for X and Y along with the Minux Z are shared.

In the HAL file I can do a
loadrt charge_pump
but an
addf charge_pump
fails with
function 'charge_pump' not found.
If I leave that out and run MachineKit on the Beagle I do see
tool changer be CANopen based.

nnected to a decent Cape is to run MachineKit but instead of the Axis

of both worlds. A small

This is all still kicking the tires. Maybe a PIC32 would be an easier solution.
