Assuming you unplug the rotary axis when you remove it, you could simply use a
normally closed homing switch that unplugs with the axis. Problem with this is
it wouldn’t let you use the fast approach, slow home sequence with a single
switch.

Maybe I am thinking too simplistically, but my approach would be:
Start with my 3-axis config
Copy it
add the fourth axis information to the copy
change the name of he config to 4 axis.
The steppers I used cannot have the motor connected while powered. So this
method suits me.

Greetings all;
out of the logic that determines whether the machine will run gcode when
that A axis has not been homed because its unplugged, off the machine
and stored and either is unhomed, or was never homed since this power
up.
How is this best done? Preferably done so that a powerdown

Please let this thread die. This is an argument based purely on personal

Gene,
And that is why if you had bought a comparable machine state side from a
reputable manufacturer who would have stood behind it and supported it you
would have paid 5 to 10 times as much for it. You'd have been paying for those
services not just the machine.

That does tend to drop a wrench in the gears. :(

Hardware driver ( IRAM256-2067-A2 ). The software side of things works
really well.

Impressive Sam. Added a brownie point to your video. It would be nice to
see the block diagram of your setup. What impressed me is
With rt_preempt realtime - I have had pretty good luck with laptops..
(although the one I have in that video is probably the worse one I have
found so far.. - it runs a 500hz thread 'ok') my previous laptop ran 1khz
no problem.
