Circa 1990: Have you heard of the new Hubble Cocktail? It's very expensive,
comes in a hand polished glass, and after you finish it, your vision is all
blurry.

PLA should have enough flex for the part of a cycloidal drive that has to flex.
It also is pretty tough so wear would be a minimal issue. Just don't run it
fast and/or under a bunch of pressure without some lube. I suspect a silicone
grease made for plastics (like that sticky white stuff often

Why I asked.
Well, the Quad IV C has a gantry with 1 um glass scales on
it, apparently. The Quad QSA-30
has shaft encoders
Temperature settings (in degrees C) are in codes at the start of the g code
files so they're easy to change in any text editor.
Most of the strength in a 3D print is in the shell and perimeters around holes.
Infill over 50% is almost always a waste. Adding more perimeters does more for

NP, I just figured that was its local nick-name. Its about out of giro's
again, I sure hope that now with Elon doing our launches again, they can
figure our how to get to it for more service calls.

Have one i garage bought for similar price, however no place for car anymore.

Hi Gene,
0.01 arcsec is way too high resolution. Unless you have a telescope
with 12.6m diameter (sin(delta) = 1.22 * lambda/D, with delta the angle
in radians, lambda the light wavelength (take green 500nm) and D the
diameter.) Even then, in extremely good skies from ground level, our

Grettings all;
Using one of these 6 wire, 12 volt elderly floppy stepper driver motors,
as 4 wire on a to6600 driver I have a choice of fitting a sleeve over
the driver hub on the motor shaft, which when cleaned off is 16.8mm in
diameter, meaning the minimum tooth count for a GT2_3mm belt will
