CrealityK1 Max 3D Printer Smart AI Monitoring 600mm/s High-Speed Printing XY Design Auto Leveling Large Build Volume 11.81x11.81x11.81in Dual-Gear Extruder for Precise and Efficient Printing

= What I WantedAs I am new to 3D printing, I wanted something that:- Easy to setup and get going on- Sufficiently capable to avoid quickly "outgrowing" it- Affordable (<$300)= Why I Choose the Ender 3 ProI was torn between the Ender 3 and the Ender 3 Pro. I settled on the Pro, as I figured that the Pro represented the best and most refined version out-of-box. The Ender 3 is a tried and true model with it's strengths and weakness well known. There are numerous howtos available on how to address the various short comings of the Ender 3. However, several of the enhancements offered by the Ender 3 Pro are either more difficult or cost - approaching or exceeding the cost differential between the 3 and 3 Pro. For example, the upgraded (sturdier) Y-axis base is more difficult to do on your own and requires significant disassembly and reassembly. The upgraded PSU is nearly the cost difference alone and results in an unused item in your drawer that you paid for.= Out of the Box ExperienceThe printer was easy to assemble and worked well without any modifications. It is critically important to get the bed "level" - not as in bubble level but as in consistent height from the extruder nozzle (I used the paper method). It is also important to make sure that the wheel/track assembles are straight and true with proper tightness. I found several helpful guide videos online for this specific model that do a good job of walking you through it.My device came with the latest FW at the time of writing (1.1.6.2), so I have no experience in FW flashing yet. I do plan on setting up an OctoPi/OctoPrint solution, but for now the including SDcard and adapter has worked fine. I've printed with both PLA and PETG and both come out surprisingly well in my opinion. I've been using the latest version of Ultimaker Cura at the time of writing (4.5.0) for slicing STL files.= Notes on UsageA note on print times. I have no experience from which to base my expectations on print times however, you do need to be patient as many prints can take 5, 10, 15+ *hours*. I haven't tinkered around much with the print settings to see how much of a reduction in time I can achieve and at what quality tradeoffs. Nor have I experimented much to see how print quality and time stacks up when printing multiple parts simultaneously versus multiple prints of singular parts.You should monitor your prints - initially to make sure it lays down a good first layer that adheres well and then periodically check on it to make sure it doesn't go awry. Also, make sure you have enough filament to finish the print and that you plan for the duration. Things like- Are you comfortable with it printing overnight or while you are away?- Will the printer be free from vibrations/bumps/drafts in it's location (e.g. dining room table) from foot traffic, AC vents, etc for the duration of the print?= Final ThoughtsOverall, I've been very happy with this purchase and foresee a long service given it's performance, upgradability, and available of spares in case of part failure.

Worth it 100%, very realiable, I already have about 800 hours of printing with no major issues. If you want to get into 3D printing, getting a Creality k1 Max will save you problems, trust me. Very easy to use and feels modern. I already have two of these.

I LOVE MY PRINTER!!!! It was a little bit of work to assemble, but there was no room for error. There were no adjustments that could be off. All pieces attached one way with no slack. As a result, I leveled it once, printed, had a failure, made a small leveling adjustment and have been printing for a week almost 24 hours a day with no problems. 11 hour prints, 8 hour prints, all working fine (OK, I had a kink in my filament and got spaghetti, but not a fault of the printer.) Yes, it has a plastic extruder, but use it for a while before you go and swap it out. I think it is a very good design, it has adjustable tension, the extruder gear is the same as the upgraded extruders, and the tension pulley has a smooth running bearing on it. The flexible magnetic build plate is a nice touch. The textured surface does not affect your bottom layer (Still smooth) and allows excellent adhesion. I tweaked my bottom layer a little TOO thin and it was hard to get the brim off the bed. (a brim is a couple lines around the model that I like because it shows if the bed is level and gets the flow moving smoothly).After a week of printing, I did install the https://amzn.to/2NIQ00D 4.2.7 Silent Upgrade board. While definitely NOT REQUIRED for smooth beautiful prints. It REALLY is much quieter. The fans are the limiting factor on noise, but that is a constant, even white noise. Not the R2D2 noise you get from the stepper motors. With this board, the printer is literally at my elbow and I have to look over to see if it is still printing.Summary: The printer, purchased just as it stands, is a fantastic deal, prints wonderfully, takes a little bit to assemble (but is still doable for a novice), and Oh, the flexible magnetic build surface is a nice touch.

Well built. Well packed but (see issue). The printer is fast. Print quality is excellent. Support is good. Klipper implementation for WEB control is adequate. However, if you are used to working with the full version of Klipper, you will feel constrained with your settings options. Almost all of the finer adjustments will need to be done in the "Creality_Print" slicer software. One small example is pressure advance.Issue - The printer arrived with the glass door shattered. The outer and inner shipping box showed no damage. What was left of the door and protective film was still taped to the chassis and in the shipping bag. I was able to clean the safety glass cubes from the chassis, drive screws, support shafts, and belts. Re-greased the screws and shafts and ran the initialization. Everything checked out OK. Creality customer service is sending a new door (after the Chinese new year). So I cut out and installed a plexiglass door until the replacement arrives. Not so sure about the glass door choice as it seems that it can be broken without an obvious sign of force.Look forward to firmware updates and I hope some Klipper genus takes the time to wiggle together a full version for this printer as Creality does give you the option to root itOther than the unfortunate door incident, I am satisfied. Like I said very fast and accurate which is what counts in the long run.--- Update ---Klipper genus is on Github by the name of Guilouz. Full Klipper implementation. Easy install (and uninstall). Supports the touch screen with Guppy. Yes, there is some Linux involved. But it is a copy and paste into a terminal program (SSL). Mainly to run a text menu so you can choose what you want to install.
