After looking at the comments, and seeing the September delivery estimates for the parts req'd based on the BOM, I realized I actually have an extra S3 (Unused) printhead assembly which I'd needed for my S3, but haven't gotten around to installing it.
Now wondering, would the S3 printhead be an easy mod for my UM2+ or should I just go with the BOM and order the necessary parts?
Really amazing work btw.. I almost feel like I owe it to your efforts and should just build this DXU project rather than cheating with my surplus S3 Printhead. 😉
