I went and talked myself into a nice shiny new K1 Max a couple days ago and bought it through Amazon because it was fast shipping.

It got delivered yesterday but sadly I got sent a obviously used printer. Fingerprints all over the glass top, it was missing literally all the accessories, including the spool holder, and the re boxing job was very bad. The two small pieces of foam that were there were just loosely tossed in the printer. The bed and carriage were both just floating in air.

Needless to say, I never even took it out of the box. Called Amazon and had to do a return/refund as they had none left in stock.

So now I will be re ordering direct from Creality and I can't find info on shipping times so I can plan around the delivery.

Broke down and bought myself a K1 Max yesterday to replace a 10 year old scratch built of the same size. It will be here tomorrow.... supposedly.

Based on my past experiences with things over the years and looking at everything on the printer, the first thing I noticed that I'm not crazy about is the routing of the bowden tube.

I already have the thought in my head to reroute that and potentially moving the runout as well..... if possible, but I will need to see everything in person first to work out options.

I also plan on leaving the top glass off permanently as I only plan on printing PLA 99.9% of the time.

I've also seen several mentions of how noisy it is with all the fans running, so I already went through Creality slicer and found the setting for the side fan and turned it off, and depending on the wiring, also plan on disabling the rear exhaust fan as well as I know it won't be needed.

As far as anything else goes, would any experienced users have any other "little" things that you've done to your printer that made it just a bit better?

I actually have two showing up this weekend, a MMU2 and parts for a MMU3.

Still haven't decided exactly what I will be doing with them, but it was one of those "prices I couldn't pass up" types of things and curiosity got the best of me lol...

So far I am thinking the 3 will be going on my MK3.5, and haven't decided fir the MMU2 yet. I have a couple MK2.5s and a MK4, probably will end up on one of the 2.5s at some point.

The questions...

I very rarely actually have a need to do multi color. If I mostly do single, does that still need to run through the MMU or can I just disconnect the tube between the MMU and extruder and run it "normally" as before and just reconnect for multi color?

Second question is regarding filament runout.

Does that still get triggered on the extruder or is that in the MMU now, and is the option to automatically switch to a fresh roll on runout available yet or able to be added?

I have a possibility to pick up a MMU2s for fairly cheap.

I was digging on Prusas website as I was fairly sure they offered a upgrade kit to MMU3 but I can't find anything at all. Even digging on google I can't find anything other than full MMU3 kits or links to up[grade instructions.

Also I was planning on using it on a MK3.5S, but I also can't find any info on doing that eather.

Did they actually have a kit or am I just imagining things?? And does the MMU3 work on the 3.5S?

Edit: pics of the splitter in the comments.

I'm working on a MMU1 project and I downloaded all the relevant parts right from Prusas page on Printables.

Used Prusa PETG with their settings on a MK4.

Everything printed nice and looks good, but I noticed that the filament path and fitting holes in the splitter and extruder housings are a bit more oval than round. Like they are slightly "smooshed".

I am able to run filament through them, but it doesn't seem to be as "smooth" running it through as I'm thinking it should be.

I've never had any issues before with Prusa parts or anything else I've printed with the printer.

Has anyone else ever run into this? I don't want to run a drill bit though them, at least not on the splitter for sure, as I don't want to chance messing up the filament path.

The large pad with the ship builder.

Is there any way stock or with mods to get it to sink farther down into the ground, like almost level or just a little higher than the ground?

It's nice to have but no matter where or how I try to place it, it's always way too high. Always too many flights of stairs to get up and down.

Been using the program for a while now and do like it, but the one thing that bugs me is the "waiting for network" bit every time I reboot the PC.

I don't always have my internet on and it's kind of annoying that I need to turn it on just so the program will start.
