Thanks. The example is clear. All that is needed s a user-space app that
can talk to a user any way it wants. Seems the details are all abstracted
away in hal.component
I can think of a bunch of maybe useful experiments to try.

Why not print the classic "Benchy" boat, and only try to make working parts
when that works?

Idea: Make a printer with two tanks. One resin and one IPA.The
printer raises the part out of the resin then the tanks moves on a rail and
the platform goes back down but this time int IPA tank and the platform
move 1mm or 2mm up and down

Hackaday has a series of articles under 3D Printering. The latest, #42, covers
cleaning resin prints. The basics are use two IPA washes. One for initial
cleaning to get most of the uncured resin off, then a second one to finish.
When the second has too much resin dissolved to wash clean, swap

For a toothed pulley with a flange on both sides I'd modify the 3D model to
make one flange a separate part, with features on it and the body of the pulley
to align it so that when glued on it will be concentric.
To glue PLA, cyanoacrylate (super glue) works well. So does tetrahydrofuran,

I have contemplated building one with a base/frame made of scrap granite
countertop material, granite surface plates, or an epoxy/mineral casting.
Vibration dampening is a good thing. The high accelerations of marginally
rigid frames can induce visible artifacts.

I don't really know much about it. there is a big heidenhain service

boards that allow you to interface a 0-10v signal also which then converts
to PWM in the inverter. So I bet there are pretty standard. If I do end

The 8i20 takes DC input.
If you rectify 400V three-phase then you will get 565 V.
400V is the RMS voltage. A rectifier charges the capacitor to

There are test objects with a selection of features, including various angles
and overhangs. Try printing without support then observe which angle it goes to
a bird's nest. That's the minimum angle you can get away with printing without
support. Of course there's a setting for that. Yup, the
