But wouldn't that break the ability to home the gantry's sides independently?
That's a huge problem. The gantry isn't going to align itself. A relevant point of the context here is this is going into a community shop, with a constant stream of new users with very limited supervision. So "power down these axes and mechanically align them" doesn't sound like a viable option. In the past I've had the stops aligned and ran the gantry into the stops until both sides' steppers stalled... gently. But that sort of hackery won't really fly here. People would just be jamming it at high speeds and damaging the drives or at least keep screwing up their zero.

Yes, it would mean going with a development version of LinuxCNC rather than a released version. For aesthetic reasons I have been running JA versions on my machines for years (none of my machines require it). However for "normal users" it is maybe a step too far. This is why I was suggesting that you try running a trivkins config and use the "gantry" HAL component to link the joints. There is a sample HAL file here: https://github.com/cdsteinkuehler/linuxcnc/blob/0e0418b362f45d7ad332fa3f211cbf8c2f24efd9/configs/ARM/BeagleBone/Probotix/Comet.hal -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Transform Data into Opportunity.
