Nextruder Adjusting Tension Hard?

Folks, am I crazy? I was trying to loosen the pressure on the extruder gear as suggested by the article to print TPU, but the shroud completely blocks access to the adjustment screws. I searched, but I have to assume either Prusa or a modder has fixed this problem somehow? Or what am I missing? For background, I have a pretty early 5-tool machine (yes the one that came with the 0.6 nozzles).

Thank you in advance for any advice.

Best,

Tad.

There are several dwarf board cover remixes on Printables to help with getting at the tensioning screws heads on the XL.

Here are a couple

RE: Nextruder Adjusting Tension Hard?

What article?

I should preface it by saying that I haven't printed much TPU on my XL (also one of the first models) and didn't have any issues. Assuming you're referring to the idler screws I don't see how the shroud would block access.

Here's the Prusa KB article on adjusting idler strength for TPU: https://help.prusa3d.com/article/idler-screw-tension_177367
