FLSUN QQ-S 90% Pre-assembled Delta 3d Printer Printing Size Φ255X360mm Lattice glass platform Auto Leveling Touch Screen

I bought this printer to complement my Ender 5 Pro. I had first wanted a delta printer but was put off because everything I read said that they did not suit beginners. The 5 Pro is excellent - I avoid the bed-shifting machines which seem wrong to me. So when this came up on offer I jumped in.The printer is well packaged and relatively straightforward to assemble. It is supplied with better instructions, tools and spares than the Creality model and this impressed me for the price. First print, a benchy downloaded from Thingiverse sliced in Cura, came out excellent printed with the bundled filament. I am not used to a glass bed and it left a wide residue mark which wouldn't scrape off and from then on I had adhesion problems which I have entirely solved by cleaning the bed after each print with an IPA mix and then applying sugar water which dries to a very sticky surface and this works excellently.Prints are very fast but this does come at a bit of a cost with occasional finish quality blips and stringing which I am still trying to tweak so I will not use this for fine detail which is what the Ender will be devoted to. It has a little higher temperature tolerance so will be my machine for bigger or general purpose prints, prototypes and PETG. Connection with octaprint from my linux PC is fine.On the face of it the niggles are reasonably trivial but are the sort that irritate. The filament holder is not the tube shown but is a flat bar which is too short for some of my (standard 1kg) rolls so I am reluctant to leave them unattended in case they work their way off it. Because the machine has a smaller user base I have not found any designs for a replacement holder and am working on one myself. There are very few fixing points on the flat top and sides giving limited scope for designs. The filament enters the extruder at a sharp angle and I have read reports of this causing considerable rapid wear so I have made a filament guide to relieve this.Loading filament is not as easy as the Ender. I have to get the filament at just the right angle to get it to fully enter the extruder and the lever is placed at the back which makes it a stretch to operate. I'm not sure how robust the extruder is and it seems potentially the weakest component to me.The printer is described as quiet. I would describe the sound as different. It does not grind like the Ender but beeps loudly at every extruder move (so every few seconds) and the movement of the arms does generate noise but not to a high level. It is recommended to lubricate the arms monthly.Overall I am happy with the printer and enjoy working to understand the best settings for it. I don't see why beginners are deterred from going here - it isn't as user-tinkerable in terms of swapping out or modifying the components as the Ender but works well as-is and I don't feel the need to change much. However the niggles seem unnecessary to me and just slightly take the edge off of it.

I looked at various delta printers and since anycubic no longer make its a narrow field for hobby/home priced units.I saw a number of negative reviews, joined the facebook group and also saw people complaining about these printers however many others raved about them and their speed and quality.Mine arrived, 90% assembled is probably and over statement, maybe its true in terms of nuts and bolts but anyway, it wasn't tricky, didn't need special tools or alignment and whilst the instructions are small and hard to ascertain detail on its pretty straightforward. I should say this is my 3rd 3d printer having already had a Makerbot Replicator 2X and a Creality CR-10 MAX but i'm by no means a "pro".After constructing i proceeded to run the leveling process, a small magnetic sensor is attached, under the print head nozzle and then to a connector and away it goes for 5 minutes moving round the heated bed checking. Then you move onto the usual paper test and set the offset to suit. It probably took 5-10 minutes in all i guess.I then proceeded to create a cura profile and slice a known object, for me this was a bit of "roger" (battle droid) i had already printed on the CR-10 and wanted to compare, one of his fingers...It ran quite a bit quicker and the quality for me was comparable, no negatives for me.I'm using ESUN PLA+, 60C bed, 200C for extruder, the printer is in my study in basement so its warm but not hot. I've not enclosed it and its stockI configured a pi with octoprint, added the printer, connected it up and sliced the droids whole blaster, uploaded and set it off, its been going pretty much 24 hours a day now for 3 days, each time i remove a print I heat the bed and re level it but thats it. Its been pretty good.Only time will tell how it fares as some have reported issues after several weeks or months so if so i will update my review but my advice thus far is, go for it. Its well price and very capable.Join the FB group if you want to do some more research search for "FLSUN QQ, QQ-S, and Q5 3D Printer Owners"

Firstly I have to state this is the 3rd FDM printer I've had. I've also owned a knock off i3 prusa and I currently own a creality cr10v2.I found it incredibly easy to put together, and the rest print came out perfect!Pros: speed (obviously), good touch interface, mostly preconstructed, includes a spare hotend, etc, includes STL files to print other spares, the touch interface is really good, and the built plate is good quality. The manual includes a troubleshooting guide and even a little slip to remind you how often you should do maintenance.Cons: I don't have many complaints, but if I must list a negative it'd be the manual. I found it easy to follow, but I've set up printers before. Often you have to rely on the images for orientation. It doesn't tell you what screws to use where. Also I feel more detail on leveling with a piece of paper would be helpful! It doesn't tell you what the paper is for at all (you need to be able to move the paper with only a tiny amount of resistance). Could be an issue for newbies. A lot of the negative reviews I've seen for printers often come down to bad leveling and the hotend getting blocked up.
