I pulled this from the loft-space a couple of months ago and it is now set up in its new home.

Some of the software has moved on. I'm still using Grbl v0.8c. I see v1.1 is available although v0.9j might be an intermediate step.

I'm now using Universal Gcode Sender v2.1.15 on a box running Crunchbang++ Bookworm v12.1

I spent a while trying to set up limit switches but encountered too many spurious interruptions. I intend to try again with screened wires.

I think I've reminded myself what it's all about. What to make next?
