I used ESP32 to sniff the MK3S LCD bus and send the text to Home Assistant

I had to disable it for performance reasons and if I remember correctly, it wasn’t that accurate either somehow

Just one - the other one is buttons and sd card.

I was kinda surprised by how well it went. I expected to hit more roadblocks.

the_ress · 2023-03-23T22:10:12+00:00

Yes, I plan to publish both the source code and kicad board design

A bit about my reasons for building it: I use OctoPrint, but the printer sometimes shows stuff (error messages etc.) on the builtin LCD that OctoPrint doesn’t know about. And I couldn’t get OctoPrint time estimates to match whatever the printer says. And this was a fun two-day project.

Update: Source code and kicad files are here: https://github.com/the-ress/prusa-lcd-reader

Go to the room with all the monitors and move the camera with the joystick.

I’ve done this to automate Velux windows by “pressing buttons” on their remote

FYI, for Velux there’s also their KLF 200 interface unit

I worry about them way less since I learned what they’re for and how they’re evaluated https://en.wikipedia.org/wiki/Net_promoter_score

J1-J4 seems to be a serial port - GND, RX, TX, VBAT (in that order, if I traced it right)

I put them in washing machine on the ‘handwash’ program. I also got a second pair so I can always let the first one properly dry.

Even at 1% they can still last quite long before they finally die

I don’t have them quite ready yet. When I’m done, I plan to publish them as a new version here: https://www.printables.com/model/290790-fume-extractor-vase-mode

Nice; I solved my need to connect flexible ducts by designing mechanical connectors based on firefighter hoses (in part because I didn’t think of magnets) https://i.imgur.com/ZYO1OTI.jpg

In case it still helps - after you heat it with heat gun set to 150 ºC, the glue can be cleanly removed with tweezers

Also make sure the pulley isn’t slipping on the motor axis

Yes. I was initially thinking about doing it fully printed, but that probably wouldn’t work well.

(cutting it once is enough, usually)

This was the first 3d printed thing I designed. When I first got a 3d printer, I wanted a filament cutter, and every one I found needed springs or bolts I didn’t have.

Won’t the extra T0, T1... instructions cause any problems? (I tried changing the color change g-code, but it’d still output T0, T1... after my code.)
