Kit's Machine

Tomorrow I will look at configuration of ports, limit switches etc. and how to get auto-squaring on the two-motor X axis working.

It doesn't have auto squaring, each motor moves independently while homing and you just adjust the home switches to square the gantry.

Pooh! I thought somewhere I'd read that auto-squaring was possible. Perhaps it was in a possible-future-devoplments chat on the CNCDrive blog or similar.

Back when I had microswitches placed where they could get smashed if they failed to operate and the old version 1 of LinuxCNC on my machine I made a micro-adjustable end-stop (OK, it was an M6 bolt in a bit of aluminium angle) for gantry squaring. That dissapeared when I upgraded to proximity sensors. I'll need to to come up with something similarly cunning for the new installation. The present arrangement is far too clunky for easy fine adjustment which is currently tuned to a hair's breadth in the LinuxCNC v2.8 config file. Once it's been made, a properly implemented mechanical adjuster will be quicker to set up anyway.
