After seeing +Walter Hsiao's recent blog posts, I got inspired to do some experiments with taking pictures in a light tent.

+Walter Hsiao Did his own version of the Cranestyle Mini.

Walter, maybe you can share with us where some of the parts were sourced? I'm particularly interested in the platform heater you used. Also, is that base a single 6-slot extrusion, or is it a couple of smaller ones put together. If it's one, where did you source it? I really wanted to find wider ones (especially for the 150mm-scale Cranestyle less-mini I've started building), but Misumi didn't have them.

Those all-metal bowden fittings also look like an improvement, but I haven't seen those ones with M6 threads.

Speaking of the bowden tube, does one that short actually work? How is the extruder mounted, and how much is it able to move?

I see an endstop switch for the X axis. Is the fan the trigger? There is also something attached to the X motor that I assume is part of the Z endstop trigger. Personally, I removed all of the microswitches from mine, and I use TMC2130 sensorless homing for X and Y and an inductive probe for Z.

Running that hot end umbilical from below the platform looks pretty clean, but I would worry that it would snag on things carrying the machine around. And is it long enough for the machine to reach X min and Z max without the cables encroaching on the build area?

Maybe you can also discuss some of your other design choices.

I saw this tonight from Pasadena. The sun was just below the horizon and the sky was dark, but the rocket was high enough to be out of the earth's shadow by the time the interesting stuff started happening. It was pretty spectacular.
Elon's sleigh flew past Los Angeles tonight... :-)

Which slicer do you use on a daily basis, and why do you choose it over the other options? If you use more than one regularly, what makes you decide to use one or the other? There have been polls on the popularity of various slicers, but polls fail to cover the "why" part. I'm looking for reasons to recommend one slicer over another for certain types of jobs, or to certain types of users.

Put together a little article with +Whosa whatsis about one of our pet peeves: how to define 3d printing "resolution." Check it out at the link:

My first class with +Whosa whatsis on Lynda.com has just been released, "Additive Manufacturing: Optimizing 3D Prints."

Lynda.com classes are behind a paywall, but they have free trials! Many schools also have subscriptions.

The class on Lynda.com: https://www.lynda.com/CAD-tutorials/Additive-Manufacturing-Optimizing-3D-Prints/618717-2.html

Some of it is also available via LinkedInLearning:
