Good timing with this. I had an old maker select v2 from ~2015, and at some point, the SD card got jammed in and ripped the card reader off the PCB, so I just ordered a Core One (preassembled) over the weekend. The CoreXY system (and enclosure) seems more elegant than bed-slinging, but it's evidently more fiddly. Hopefully the enclosure also prevents it from accumulating dust as quickly. You mentioned you stripped one of the tensioners - does a screw thread into a 3d printed part? Is there a more robust version of the part?

> You mentioned you stripped one of the tensioners - does a screw thread into a 3d printed part? Sort of. A metal screw is threaded into a square nut that sits inside a 3D printed part. All good unless one gets to the end of the screw's motion range, after which the square nut begins to turn inside the plastic part and strips it. I have printed spares for the plastic part, also I know better than to trust Prusa's frequency detector applet, so this is not a deal breaker once you understand the system. There are much better ways than Prusa's applet to detect the belt's frequency, some described in the linked article. Prusa offers free downloads of all the printer's plastic parts: https://www.printables.com/model/1167816-core-one-printable-parts/files https://www.printables.com/model/1167816-core-one-printable-... > Is there a more robust version of the part? The original part is printed using PCCF, very strong, but the embedded square nut is too small to resist worst-case forces.
