Refined the BLTouch mount, aligned with the nozzle at just the right height, and chopped up for #3DPrinting.
We can't be shy in @marlinfw.org testing so I'm printing this with the latest motion code in development. Wait till you try it! You'll see the improvements from the first print.

It's not the prettiest part but it should do the job of getting the old Prusa i3 up and running! Maybe I'll do a little more refinement and remove some of the excess… #RepRap #3DPrinting #CAD

I took a day off for nostalgia to add colorized listings to the #Atari BASIC thing. I'm using the AtariBASIC source code (annotated with pseudo-code) to inform the tokenizer. The most important component I need to implement is the little VM that applies the B.N.F. to each statement. #CodingLanguage

The most natural way to experiment with #LLMs is to wrap up Frotz in a #Python Tkinter UI and feed the LLM the output of #Zork.
Using several system prompts for the role of summarizer, sidekick, assistant, and player.
It's important to keep context small but rich, so this Summarizer is doing well.

I printed this piece for my Prusa i3 Jalopy Rebuild. The Adjustable X-Idler has always been a bit of a joke in old brittle PLA, quickly disintegrating every time. But with modern PETG a little bit of material goes a long way, so this turns out to be a pretty sturdy part!

I’ll be live streaming later today, putting some final touches to the upcoming Marlin 2.1.3 release. This version will be tagged on Friday and we’ll patch up your reported issues in followup point releases. #3DPrinting

The runner up for #ABBUC 2021 was "Fallen Kingdom" for the #Atari XL/XE. (Ported in 2022 as a Steam game called "Chessformer.") It combines chess with a platformer containing 30 challenging levels. I needed to stretch my coding skills, so for a weekend challenge I ported the game to #Pico8!

Local #LLM Mistral Small 3.2 keeps hitting the mark. Given a succinct system prompt to convert C header content to YAML the result is strongly aligned. For the next test I gave Mistral 280 lines of C++ to convert to Python. It did the job with only one gaffe (a ternary). With that one correction, 🤌🏻!

A little off-kilter due to the metal casing coming up against the current plug wiring, but once I replace the blade connectors with direct-soldered wires it should fit perfectly.
Next: Extruder mount for 7mm frame top-left corner. Probably mounted on a bearing so it can swivel.

The old Prusa i3 is coming together slowly, new custom part by new custom part.
I just sticky-taped the PSU to the right side of the i3 frame, so I can chop off most of the bottom and side for the PSU cover….
Oh well, it's already #3DPrinting right now, but I'll add more flair to the final design.

The cheapest way to double your print speed.
Flipped over when you’re printing bookends, wide-end-up when you’re printing clones.
Bonus: Bookends mode cancels vibration in X. That’s just physics, man!

I dug out this languishing game project and installed an ancient version of #Unity3D on the 2012 MacBook Pro.
I’ll be updating GOTH to work with the latest Unity IDE in my copious spare time, then extending the game a bit, and then… making it available to the world! #coding #arcadegame

Classic black/white/silver stylings will work nicely for a clean look.
I need this #Prusa i3 revamp to be pure #RepRap — but with a 32-bit rocket engine and the benefits of 12 years of software & silicon evolution.
I have a simple point to demonstrate about the potential of hobby #3Dprinting!

This #Prusa i3 rebuild will be epic! Using the original Graber MDF frame with a lighter Y axis, faster Z axis, silent steppers, high flow extruder, 24V power, 32-bit Marlin, input shaping, graphical LCD. I want to see what @marlinfw.org 2.1.3 can do on this lightweight classic from 2013. #3Dprinting

This is also a test of the latest @marlinfw.org with improved handling of the stock Chiron bed probe.
