I've had a good evening of mostly tightening M3 nylocs. Eventually after about three hours my desktop CNC engraver went from looking like the first picture to the second one.
There were only a couple of moments of retracing my steps. The set of picture instructions you download were OK. However they've changed the design slightly and substituted some fasteners so you run out of shorter ones if you use them everywhere they suggest.
I've no idea if it works at all as I haven't powered it on, let alone installed the software. This is a job for tomorrow evening.
