Introducing The Creality K1 Max! (And how is the K1 after 100+ hours?)

The above links are affiliate links, so following them before purchase will normally pay me a commission fee.

Please note that Creality sent the K1 Max over at no cost to me.
Notes: 1. yes some artifacting in a couple of places, but hey, it's better than the interlacing. I don't know what davinci resolve's deal is at the moment. I think it didn't like the 1000x speeds. Not a huge deal. I rendered this in 4k even though only some of the footage is 4k. Let me know if that is a thing you found useful or not.
2. Yes I know the big "max" has a lot of ghosting - I did this piece in 2h12m and it's 200mm wide, I was maxing out the printer, of course you'll get this. Deadlines are a thing.

Yes I have a website now where I write random things when I have time:

It is H.264; one of the current disadvantages of jail breaking the K1/Max and using Fluidd is that it doesn’t support the codec currently. Gotta give Creality credit for using a good codec for playback that’s far superior to MJPEG.

It's nice seeing creality push into the prosumer market, I feel a lot better about these machines now that they are out in the wild.

So, Creality still violating open source licenses.

Qidi didn't do a perfect job of how they released the sources but at least they appear to have done so on a timely basis.

I ordered the Qidi X-Max3 instead of the K1 Max, and Qidi honoring the open source license terms was a major factor in this decision. Ordering the Creality would be a slap in the face to everyone who has contributed to all the software Creality are currently using in violation of license terms.

K1 Max — I bought one a month ago and am in love. I have many makes and models of printers and this is the best one in 9 years.

I'm fairly happy with my K1 Max overall. So far I've not used any glue stick at all and had great bed adhesion every print, even with ABS and ASA. The only issue was with TPU, which was _very_ hard to get off the bed. I'll definitely use some sort of seperation agent the next time I print TPU.

[TechieSewing]

Now that manufacturers like glue stick again, maybe they'll start including painter's tape with their printers. I'd like some wide one that can cover half of the bed, to get smooth texture on the prints bottoms.
That extruder changing timelapse was funny :)

I think Creality did a great job overall with the K1 and K1 Max. I advised people there would probably be some teething issues, but especially once the code is out and any early revisions are finished, should be a super solid printer.

[dtaggartofRTD]

hardware looks solid. I still worry about their software. Creality's reputation for half-baked solutions is well deserved at this point.

I'd love to see a video showing the difference between using thermal paste on the heat break or not.
I used some of the paste leftover from waterblocking my GPU, and it gave me an extra 10c before I started getting consistent clogs.
Granted, I was using $0.10 heat breaks from Taobao, but It would be an interesting topic.
If I can get rid of my Super Racer, I'm gonna be picking up a regular K1. Tired of FLSUN's crappy software and cheap clackity bearings.

0:07 Holy hell, is that lens parfocal with a constant apeture?

[Lawn_Care_Lounge_tv_uk]

i love my k1 so much ive bought another unrepaired k1 again here in uk both cost me 200 each these are return creality printer we also have a ender 3 v3 ke that we hate and dont use any more

[MTNDEWGANG]

So, for a third k1, I feel like they would make a p1p machine. No frills, no glass, probably less electronics maybe no internal cooling fan and drop it at $399-450. That would be a HUGE bomb shell.

I was excited when I built my Voron that I had a mains powered 300mm bed. I was envisioning fast heat up. With a Voron, you supposedly set the max bed power to 60 percent (with 110v). This is to prevent the bed from warping. Maybe because the LDO kit beds are very thick? I have a slow heating bed again. Not sure if this will be a future issue with these beds or not. Something else to keep an eye on.

I did a 30 hour print yesterday I've done 130 hrs on the K1 max I use glue sticks on tall parts only no need on the wider stuff

[noway]

Hear spray makes very good adhesion and homogeneous layer of glue

[thomasnixon]

It's hard to tell from the video, but they could have made the AC bed work well on 110V and 240V by splitting the bed resistance in two: the bed would have three terminals A, B and C, with half the heater between A and B, and the other half between B and C. If A is wired to neutral, then you get approximately the same power when C is switched to 240V, or when B is switched to 110V and C is switched to neutral.

This would explain why the bed power board is so complicated, and why there are 3 power wires (and earth) going to the bed. Other similar schemes could work too, for example just having two heaters with different resistances, and using one or the other.

What sort of camera does it use? Is it just USB or something else? I haven't been able to find any good info on it other than it seems like it doesn't support other USB cams for some reason despite it running a version of Klipper.
Also, why would the US 110V not heat the bed the same as our 220V versions? The heaters are built to wattage for the voltage so it should be the same output for each region. There are even some models of AC heaters that can be used for 110V or 220V depending on how they are wired so they might not need 2 different part numbers.

I haven´t used glue stick on my Creality k1 max since i got it. It prints fine even with ASA. So i don´t know if Creality wants you to use it or not but from my experience its not needed.

[d.jensen]

Glue stick ensures the print will come off as much as it ensures the print will stay on until then. ;)

[BarnesysBuilds]

Had a K1 for 3 months and overall been really happy with it, however last week it decided to pack it in and wont print anything stable anymore, under extrusion and then birds nests every print. Progressively got worse and worse until its now unusable.

So im thinking the extruder has weakened and lost precisely control of filament feed and retract and as a result ruins prints. As its the original extruder i have asked to be sent a new one and lets see if that fixes the issue. Not great after only 20 or so prints.
