If you're using a high-end bluetooth headset on your Macbook Pro it's likely your mac is using an audio codec which favors battery efficiency over high quality. This results in a drastic degradation of sound, the SBC codec is the likely culprit, read more about it here.

Find out what codec you're using

Play a song on your headphones
Option (⌥) click the Bluetooth button at the top of your screen
If you're using AAC or aptX, you can stop here—those are the highest quality codecs.

Change your codec to AAC or aptX

CR-6 post-unboxing checklist

With most of the CR-6 SE issues being due to bad wiring or loose/too tight screws I feel like it is time for a good post-unboxing checklist, to be walked through pre-assembly. Even though I do not have my unit shipped yet, I've seen enough issues and fixes that I can compile this post.

I initially posted this on the independent CR-6 community Facebook group but since not everyone wants to use Facebook (which I totally understand), I will repost it here. I mirrored most of the relevant content of Facebook to imgur.

If you have any feedback or anything that needs to be added, please let me know and I will amend this post!

Note: There are some known issues with this printer - please read the entire guide. (It is long, I know, but this is a necessary evil!)

Reverse Engineering SP110e LED Controller

Through Bluetooth sniffing, using this method I've been able to (semi reliably) control the SP110e controller via Homebridge.

You can find this controller for very cheap here: https://www.aliexpress.com/item/4000773623427.html?spm=a2g0o.productlist.0.0.4f09329cJ7C1H4&algo_pvid=542e757b-587f-4540-8652-2195883f1349&algo_expid=542e757b-587f-4540-8652-2195883f1349-0&btsid=0bb0622a16012309671478585ed4bd&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_
