What alternatives to gantrykins?

How to. 2 or more motors on one axis. Gantry LinuxCNC 2.8 Master
I'll report back
Yes basically, gantrykins was rendered obsolete with the release of V 2.8. So having built a gantry machine, thats all I've ever used... (using V 2.9 now)

Personally, I think that is also obsolete. I just hit home all as I turn the machine on so the joints become axes before I attempt to jog. Gmocappy allows you to home individual axes and I sometimes rehome the Z axis but if X is out for me, Y will be too.
I have a toggle switch to toggle between the two,
when switched to home the limits are switched to closed and vice versa
when switched to limits the homes are switched to closed.
So on the old gantrykins I would switch to home for homing and once homed switch back to limit.
Problem now is that when switched to limit the limits work but when switched to home the home don't work.
I also have probe configured on pin 15, which I could do without.
I now have in Hal
net spindle-on => parport.0.pin-14-out
net charge-pump => parport.0.pin-17-out
net estop-ext <= parport.0.pin-10-in
net all-limit <= parport.0.pin-11-in-not
net all-home <= parport.0.pin-12-in
net probe-in <= parport.0.pin-15-in
I've tried removing the "-not" comment from pin 11
I've tried adding the "-not" comment to pin 15 and or 12 and or 10 and 11
In my old Gantrykins Hal I had
setp parport.0.pin-16-out-invert 1
net charge-pump => parport.0.pin-16-out
net dout-00 => parport.0.pin-17-out
net all-limit <= parport.0.pin-10-in
net all-home <= parport.0.pin-11-in
net estop-ext <= parport.0.pin-15-in-not
Yea, I've sort of come to the same conclusion. The toggle switch was how I set it up in Gantrykins some 6 years ago.
I found this "Plasma Table HAL example, in git and a 9-part video series was created by swolebro" excellent post and am working through that now.
