Has anyone had any experience with, or seen dual X axis endstops using a arduino UNO? I’m building a new machine, and I have dual steppers for my X axis, and a driver for each.

I didn’t think the uno boards had enough pins for 4 drivers. You have to drive them separately, so they at least need separate step pins, and then you’d have to do some backflips in the firmware to keep the same dir and enable pins, but it would be possible.
I did not think of that, as I planned to parallel the signal for the X axis. But with that in mind, it probably is not possible. I suppose I may look into another board after I get the mechanical parts all working and squared up.
IOn a side note, I cut some decent pieces of aluminum on my Lowrider. 6mm plates, made the cuts in 2 passes.
Nice.
Since you like grbl, you might try the grbl_esp board: https://www.tindie.com/products/33366583/grbl_esp32-mpcnc-cnc-controller-ver-122/
There is also a port for grbl for Ryan’s rambo, or you can just try the rambo with the firmward Ryan uploads on it.
