Great set of features for the money, and a huge build surface to boot. Love the flexible removable build surface, although I still need a little hairspray to ensure that first layer sticks perfectly.

My other printer is a Monoprice Maker Select v2.1 and this one feels a lot better in terms of build quality. I do get some clicking from the extruder when printing, but that could be a combination of my settings and not being familiar with a bowden setup.

I'm not really a fan of touchscreens and printing from SD card interface is tight and doesn't ask for confirmation so it's easy to tap the wrong thing, so loses a star for that. Perhaps fixable with a firmware update.

Best of the four printers I own. The machine is well built and functions quite well. The ‘manual’ is pretty sparse and there is not enough information on exactly how things work. If you are familiar with 3D printers this is a great deal. If this is your first, and you need lots of information on how to set up and use it, then you will have to get some of that information elsewhere.

I was excited to purchase this printer. I really liked the large build size, which was the major reason for the purchase. I’ve had it for three weeks and have had only one print that is close to good. Problems that I have encountered include:
•Filament not sticking. I spent two weeks just trying to get the first layer to stick to the bed. After spending over two hours with support I finally got the filament to stick. The interesting thing is that the sample cat model printed perfectly but nothing else would. After lots of autoleveling and tweaking the Z offset and bed temperature I finally got something that worked – kind of.
•Y layer shifts. Even after turning off the jerk option in Cura the Y axis still shifts towards the back of the machine. The result, of course, is more ruined prints.
•Stuttering. In the X and Y axes the bed seems to stutter in that it moves a short distance and then stops for a few milliseconds and then starts again. It does this every 2mm for a distance of 1mm. Not only annoying but it ruins the print.
•Lousy manual. Parts identification at assembly time caused confusion. Also the supplied photograph of machine model selection in Cura showed Monoprice options but there were none in reality. I had to contact support who suggested CR-10.
I have an RMA and will return it today for a refund. The sad thing is that I bought this because of the quality and performance of my Select Mini V2. I just wish that printer had a larger bed.

First, as seems to be consensus, the instructions are beyond horrible. I had to puzzle over the fact that the rectangular frame has a bar on the bottom that must be removed before affixing it to the base (yes, there's a sticker on it that says Remove I eventually saw, but good instructions should include that). There's no indication that one bracket for mounting the frame onto the base goes on a specific side.. The instructions reference finding a screw with a 'red circle' which I've still not found, but I did figure it out. And once complete there were several cables that were not plugged in... fortunately they all had different connectors so I was able to piece that together too. and no mention of magnetically attaching the print head . I had a lot of interpolating to do in order to assemble this unit. Eventually it was done... I replaced the power cord with one of reasonable length... and the unit powered on.
Next up was feeding filament. and what a nightmare! I had a hard time getting it through the extruder and into the tube, but once it hit the print head I could get it to go no further. I checked the Monoprice site for help and saw two new 1 star reviews and thought 'what have I gotten myself into?'. I also couldn't find any help for my problem. At this point I requested an RMA number as I planned to return it. I still might, but there's more.
I *really* wanted a cubic foot of build space so I persevered. I figured out that there's a little blue piece on both ends of the tube and if I hold that snug then filament feeds ok. Finally I had some filament coming out of the hot end.
I was a nervous about the complicated instructions regarding auto leveling and Global Z Offset. I also wasn't sure if I needed to put a layer of painter's tape on the build plate along with some adhesive or something as with my existing printer. The auto level function seems to navigate the print head around the base plate taking measurements in multiple spots. That seemed ok. I never had to adjust the whole Global Z Offset and I'm not really sure why I would. I see other reviewers saying Monoprice doesn't know what auto-leveling is. Maybe I don't either, but that seemed to work ok.
After playing around with painters tape I found a video. The guy in the video was printing directly on the base plate so I removed all of my tape and tried that. It worked. I got a nice clean couple of layers from the demo of a 3D cat they included before cancelling and inspecting it with a magnifying glass (plus I learned about the two tabs on the build plate that allow the magnetically attached top to pop right off (no mention in the instructions). Looked good to me. So now it was on to printing something I actually wanted to print.
I downloaded and installed Cura and there NO choice for the Monoprice MP10. I tried the CR-10 printer profile (as another reviewer indicates tech support recommended), but I had no luck. In fact I was so frustrated I went back and tried the included demo file of the cat again... and that worked great. I assumed it must be bad code I was producing. At this time I did some digging. There's a driver.inf file on the included mini SD card and this printer appears to be a rebranded printer. I looked for Cura profiles for that printer, but also came up empty. I questioned why Monoprice would show pictures of Cura with a fake driver in it and then it occurred to me... maybe the included Cura 3.3 software had one so I installed that. Yes, indeed... if you download Cura 3.6 or use your existing Cura software then you won't find the right profile (and the CR-10 sure doesn't seem to work), but the included Cura 3.3 DOES have a profile for the MP10. I used that to generate my code file and it printed without issue.
One other note as I think about this. One of the reviews made reference to where the Bowden tube cable is and I DID have an incident where that got caught on the build tray during leveling and it pulled the tube right out of the print head. Not good. I was able to get the tube back into the print head after a bit of fiddling.... it just seems to snap back into place... still kind of scary. I've been analyzing how that could have happened and. I'm watching to see if it happens again.
Setting this thing up has been a royal pain... it's taken at least 8 hours of time... most of which could have been alleviated with some decent instructions. It's obvious they imported this , barely put any effort into the instructions and said 'ship it'. Monoprice should pay one of us reviewers to rewrite their instructions. That said... if I continue to get results like I did last night from here on out then I'll keep it and will be satisfied with it. Time is ticking on my decision.
Update: It's been a few weeks since I first wrote this and I have kept it and printed many things including a miniature boat, paddle controller tops, and some cases for some electronics projects. It's been a breeze to use and changing filament went smoothly.

I was very optimistic about getting this printer. I started my 3d printer with a tiny printrbot simple wooden built and then made my own I3. I sold my I3 to help purchase this unit and could not be more disappointed. I will start with my list of problems and explain a little.

1. Print bed auto leveling - Not a fully automated process as expected and makes the process harder than what it would take with no sensor. You must start guessing what you z offset would be, then run the leveling process. No real way to check with a piece of paper or other method. You must try to print and observe then cancel job if it is off and repeat this process over and over again until you get in the ball park. Once you get a first layer to stick the functions will allow you to make adjust while running a job which is nice. So this took several hours to get... Hopefully just small adjustments are need from now on.

2. Filament sensor is flaky, it has stopped my jobs several times claiming to be out which it was not. Hitting the resume will start the job again without touching the filament or sensor.

3. Y-Layer shifting, this has happened several times and ruins the print. Support told me to slow down the prints but this solutions has not worked, still having this issue which is what prompted this review.

4. WIFI - I have yet to get this working at all.

5. Instructions and Documentation - Instructions don't match product, No selection for this model in Cura even tough it is shown in the directions, support told me to select the Creality CR-10 profile to work around this issue.

6. Support - They are clueless on this product, no experience with it and don't even no its features let alone how they work.

When it works the quality seems good, Product visually appears nice.

I do like the bed size and magnetic feature. This one might be a return RMA as I have gotten nowhere with my issues with support.

My wife purchased this for me for Christmas. Upon setup (to replace my aging and smaller Ender) the printer seemed pretty solid and well built, and typical quality I would expect, though the instructions left much to be desired (which is common for 3d printers).

+ its a huge build area for the cost involved, and the setup is easy.
- the bed auto bed leveling is a joke
+ easy to level by hand and does give close error correction adjustment
-useless add-ons that cause problems like the silicone sleeve, or options that do nothing, like wifi
-extremely poor instruction manual that does not detail the process. had this not been a replacement for an older 3d printer, I would have missed several key steps if I only followed the instructions

The problem is that the design of some of the components. The silicon thermal sleeve around the hot end is too loose and doesn't fit it well at all. That sleeve ruined a few prints until it eventually got in the way, and my printer started extruding into the silicone sleeve, which ended up with my hot end and printer head ENCASED in PLA.

To make matters worse, Monoprice, at the time of this review does not have replacements print head and hot ends under warranty and they do not have replacement build plates (as it is VERY flimsy and will bend easily, I recommend using a mirror or glass) and is out of stock on the nozzle, which they only offer in one size. MP couldn't even tell me if its a rebranded product so I could find the product build plate. This is a horrible purchase experience and couldn't warn people away from this product enough.
