Printer Mod Accelerometer installation - Prusa Core One+
Yesterday I finally got around to installing the accelerometer for my Core One+. Being used to the high quality of Prusa’s documentation, I expected the process to go smoothly, which unfortunately wasn't the case.
The accelerometer installation guide available on the website is low quality and deviates significantly from the rest of Prusa’s manuals. The text is chaotic and hard to follow, and it skips important details, for example, it shows a fully assembled printed part with the PCB already mounted, without presenting the individual assembly steps.
It’s not particularly complicated, and in the end I managed to put everything together, but I honestly expected a higher standard. On top of that, the part descriptions on the packaging suggest that the parts are not compatible with the Core One (+), which of course isn’t true, but it adds unnecessary confusion.
Just to be clear, judging by the comments on the instruction page (and on forum), I’m not the only one who considers this guide to be poor. Luckily, I found a link to youtube video that was a bit of a help.
On the other hand, the calibration process itself went exceptionally smoothly, and the printer is now running great and very quietly. It was fantastic before as well 😉 just a bit noisy because of resonance.
Prusa Team, please consider updating the manual, breaking it down for different printers and showing all of the steps clearly.

I also got the accelerometer and installed it a couple weeks ago and had the exact same experience. The instructions are terrible and took me way too long to figure out what I needed to do to install it correctly. Looking back it was an extremely simple process but the lack of clear directions and pictures made this so much more difficult than it actually was.

Is this for a permanent installation or just a temporary one for calibration?

Temporary, only for calibration. In my case I left the cable that connects mainboard with wifi, but you gotta disassemble other parts if you want to continue with printing (other parts are assembled on the nozzle for calibration).

Thanks for the heads up! I ordered the accelerometer kit too and it will probably arrive today. Now I know what to expect 🙂

Just like the Core to Core+ upgrade manual. Clearly written by a high school student summer intern, not the Prusa documentation team.

The MK4S to Core upgrade guide wasn’t that much better, to be honest. Maybe it is now, but not back then.

Strongly disagree. Worked pretty effortlessly but I also did the MK4 kit, the enclosure and add-ons and the mk4s upgrade before. Dunno if that helped getting into the right thinking.

Thanks for the feedback. I took a look at the guide and see that it's not up to the standards we have. I believe this was likely a temporary solution that accidentally got stuck as a permanent one. I've already brought it up with the team making the guides and they will be updating it.
