In this chapter, you will upgrade the old Y-axis belt tension mechanism with new parts printed from PCCF material.
⬢The latest MK4 units might already include Y-axis parts upgraded to PCCF. If your printer has these, you can skip this chapter.
⬢To verify, take a closer look from the underside of the Y-carriage and inspect the parts:
⬢New Y-axis parts: PCCF has a dull, slightly grayish texture
⬢Old Y-axis parts: PETG is glossy black
Ensure you thoroughly check before skipping.

Could not do the upgrade, wasted 1h. At step 7 the nut is not supposed to be able to rotated freely in the part. It did in my part. Missed this and thus I was not able to finish step 11. Not a good experience. Had to undo the upgrade and use the old part which was snug enough to catch the nut. Not a good experience at all

I'm using the modified part which is better than what Prusa provide (https://www.printables.com/model/814369-mk4-y-axis-overhaul-reduce-vertical-artifacts-on-y)- I guess I'll have to reprint the parts to ASA instead of originally PETG.

I had to reprint these parts recently (prior to upgrade to 4S). When I did, I used Prusa PC-CF for them.
Are these the same design as in the Mk4 build and the only difference is that they're PC-CF, or is it a different design? Meaning, should I use the included parts if I've already printed the Mk4 version in PC-CF?
TIA, Erik
