After a few hickups I finished building my MK4 kit and Tukkari enclosure. The first few prints have been fantastic.

My MK4 kit had a couple bad bearings, so I replaced all the bearings and rods on the X and Y axes with MISUMI equivalents. I noticed that they have a fair bit less slop in the movement and are overall quieter.

I also made a custom G10+steel print sheet, and it’s working exceptionally well with PETG. It sticks strongly while hot, and doesn’t release until the bed drops below about 40 deg C at which point parts pop off easily. It leaves a super gloss surface on the first layer as well. If anyone is interested in building one, here are the parts I used:

(white 250x240x1mm g10 sheet) https://www.aliexpress.us/item/2255801004367032.html

I bonded them together with 3M 200MP double-stick tape (which is thin, strong, and heat-resistant) and filed notches in the g10 to match the sheet. I didn’t abrade the G10, PETG sticks perfectly while glossy. I was very careful about cleaning it with iso. alcohol before printing, and I wipe it again every print or two.

The filament dryer is a Sunlu S1 Plus, which has a built-in fan to circulate air for better drying. I printed this guide and used a PC4-M10 fitting and 4mm OD teflon tube with it to reduce friction into the enclosure:

I’m quite happy with the setup. It is a little noisier in the enclosure than just on the table due to the melamine particle board panel vibrating while suspended on its plastic feet. I’ll set it on foam and/or a paver eventually to improve this.

    There’s a reason my mk3s is the one I have as a fallback. It’s really easy to service and I find it doesn’t need a whole heck of a lot of tweaking. I imagine not having to set z height is nice but I haven’t found the need to change it once it’s dialed in as I pretty much only use the satin build plate and don’t change nozzles often.

        I wish there were comparable products because I want that build surface for my voron, it’s just a bit smaller than an xl so there’d be some overhang.
