I was just going through cleaning things up on the forum and making sure all of the manual releases were up to date. I realized the final version of the R2 SKR manual was never posted on the folgertech drive.
It is marked as v1.5 SKR. If you have the old controller before the SKR update, use the prior manual version found here.
The final SKR version can be found on my personal drive here.
The links in the official post will be updated if/when they get uploaded to the official drive.
