Good job. I know I've also said, "Don't break anything" under my breath. I liked the voice over comments. My MMU3 for MK4 shows up tomorrow, and I already feel like I've built it 🙂

Haha! Thanks so much! Great timing!

Finally I received my MMU3 for Mk4. While I was waiting I watched your and other video's about the assembly (2 or 3 times :-)) , thanks to that putting mine together was a walk in the park. I have my filament on a dedicated shelf above the printer on "integrated auto rewind spool holders" (by Vincent Groenhuis). Just finished a torture test with 500 filament changes without any issues, it works like a charm. This setup eliminates the filament buffer completely and I think it has the smallest footprint possible. I'm looking forward to see your upcoming multi color prints with the MMU3.

Oh I'll definitely check that out. Thank you!

You made that look very easy. 😀 I really like that you have the steps superimposed on the top left of the video. Regarding the zip ties. If you want to get the zip tie to go in from the bottom of the electronics cover, just bend the last half inch of the tie at a 90-degree angle. That should allow you to get it through the hole. I would go back and trim the sharp ends of the tie wraps that you left with your scissors using your filament cutters. You can get a very nasty cut on one of those zip ties.

Oh, I'll try that. I always trim my ends off but I'll keep an eye in that. Thanks so much!

looking forward to your first mmu prints with this, I have only made a 2 color sheep and poker chip test prints so far, might try an 8hr + 5 color on the MK4 this weekend

Yeah I made the sheep and was happy with that. Got distracted by editing. I need to try out some more things. Thanks!

How comes you didn't make the parts yourself? I usually download Prusa's gcode and slow the print down for improved quality. That ringing triggers my OCD a little, although I might be a tad weird like that admittedly.

I was thinking the same thing, how in the world of input shaping do they ship parts looking like that.

@@kazolar Actually they do print as fast as reliable possible, with 0.3mm layerhight. I am also pretty sure they also still use mk3´s without input shaper in part of their printfarm. Functional parts do not need to look nice. Printing time and cost of printers matters in production. For this reason I prefer printing myself (exept my first mk3 of course - it´s a hen-egg situation). While it can take a lot of time if you print slower with less layerhight - if your printer stays at home it does matter. Also if I go to work in the morning coming back after 11h it doesn´t matter to me if the printer has printed 5h and waited 6 for me or printed 11h and just got ready after I arrived. Also waiting weeks for the kit to arrive the printer has more than enough time to print parts in it´s finest quality at home.

I printed some of my parts for the MK3S to S+ upgrade. And I ended printing a bunch of parts I didn't need, thought the .6 nozzle would work which made the holes super difficult to get screws/bolts in. I'd just rather make sure everything is going to work before I start building. But yes sometimes I see weird thing son the printed parts from Prusa too. Thanks!

@@tada3dprinting Another aspect often missed: Even with heavy industrial shelfs, you can not totally avoid vibrations of neighbouring printers influence each other. Input shaping can just compensate for each printers own vibration, but not for vibrations introduced by other printers around. So a printfarm with a quite density of printers sitting side by side is quite different from a home setup. Input shaping and rigid shelfs still do a great job, but you will not get the same results as you do with a single printer or printers with significant more space between. Combine this with quite high speeds in a printfarm, using bedshakers and optical properties not realy being the priority for functional parts, I am still quite impressed with the results prusa produce in their printfarm. But of course I prefer the results I get on my mk4 with more conventional speeds, sitting in an enclosure on its own table (or at least being the only active printer on this table).
