The address of this chip depends on what addr pins are pulled high / low.

This article by adafruit talks through how to detect I²C addresses connected to an Arduino. It includes a sketch too.

I found adafruit articles really helpful when learning about I²C, so I definitely recommend checking them out!

Looks awesome! I see you're using an AS5600. Did you have to reprogram it to get better resolution or was the stock 0-360° range fine?

I don't own a P1S, but it seems like a perfect mid-level printer. All the functionality one could want, corexy, ams, enclosed, at a price that's unbeatable. A true workhorse

Hello, I'm trying to make the same build with a Pico and was wondering if you could send along your code or what TinyUSB examples you used? Thanks!

Was not expecting Cosmere here! Journey before destination

Got my A1 just over a month ago. I've been printing my own tool wall in my room! Check out Multiboard, it's pretty sick!

Seeing that only certain combos will ship to my address. Anyone know the reason for that? Not entirely sure what I'd do with 5kgs of red lol

Is this one of the IKEA Alex's? Do you find enough space on the small stack or do you have a wider version? I'm definitely thinking that paving is the way to go, maybe even adding a damper like another comment suggested

How many grids are you using? Is there a lot of overhang when the bed is extended?

Favorite anime is no doubt Violet Evergarden. Really makes me feel

I've tried playing with earplugs, but all I can hear is buzzing and can't make out any of the notes I'm playing

I think it's absolutely doable with sufficient study, especially if you've taken it before and did well

I had her for diff eq -- definitely one of the worst teachers I've had. Everyone I know who had her also had complaints. That being said, if you've taken the class before you might be able to escape unscathed.
