hi folks sorry been extremely busy.

i've managed to work out some superb settings for the mendel90, it's currently operating at *200*mm/sec, with a layer height of 0.15mm, and the prints are coming out with smooth walls most of the time. i'm deeply impressed with the mendel90, now - it's only taken me 18 months (!!) to get the right settings.

the bamboo plywood is in place, successfully - i put a diagonal cut on each edge, and a matching groove into each piece of 3d-printed plastic, only about 0.8mm depth (it's supposed to be 1.4mm but it prints out at less than that) - and the panels hold perfectly.

not only that but they hold sufficiently well that i decided to use them for structural support on the screen edge. the screen hinge has proved particularly tricky: it's quite a small piece, taking a huge load because it contains the friction hinge. turns out that if i jam the bamboo panel into it (and its neighbouring pieces), the screen hinge stays still under load. i'd previously tried all sorts of tricks to get the screen hinge to "lock" into its neighbouring pieces and it wasn't working: the plywood does a really good job.

am still making minor adjustments, chewing through PLA like it's no tomorrow, photos to follow, then they can be sent to crowdsupply.
