K280 Delta DIY 3D Printer kit with Auto-level,Large Printing Size 280X600mm,Fast Heating Bed to 110 Degree

The instructions for building this thing were virtually non-existent and it clearly was designed embracing a policy of “only the dumbest way possible.” Why they would put dozens of crucial screws in places that are nearly impossible to reach with the included Allen wrench (or any other tool), wrenches that are the wrong size for the included nuts, etc idk. Complete pain in the ass that has taken many hours longer than the build should have needed imo (it took me a total of 18 hours or so). Starting in on day 2 of building this thing shortly. Note I said day, I already have 8 hours on the project.Edit 1: so here we are at week 3 of trying to get this hunk of junk to actually print. Literally everything with this build is a ridiculous pain in the ar$e. It also appears as if there is a decent chance of faulty electronic parts like the autolevel device (which means it ALL goes back in the box and gets shipped back all for a piece the size of a dime). If you're looking for anything that isn't days to weeks worth of work then deff shop somewhere else. Since the autolevel device came busted I either have to pack the thing all back up (hours of work at the very least) and ship it back just to get a piece that is about the size of a quarter. If that's the case, I plan on following my own advise and shopping elsewhere for something with less hassle.Edit 2: I returned this garbage printer and getting one by flsun that’s just a little shorter (320mm printable height). The He3d printer is a nightmare plain and simple, nothing works the first time, support is all forum based and spotty otherwise good luck getting a reply from customer support, I still haven’t. Seriously don’t waste your time and money with this pos, get one that works right the first time.Final edit: my Flsun Super Racer arrived yesterday, took maybe 20-30 min to build, has a super nice touch screen and was clearly built in a “let’s work smart not hard kind way.” Calibration was pretty trivial and it looks super swanky in comparison to that he3d crap. If you get nothing else from this review at least He3d my advice and do NOT buy a damned thing from He3d, they are using false advertising and are straight up a scam. I should also mention, the one I got in replacement for the He3d garbage was in fact cheaper and WAY better quality manufacturing. Sorry, the pics of the He3d printer refuse to load for some reason, I’ll try it again from my computer later.

I didn't like that the instructions were not clear and the 2 prong power cable was not safe the machine is very loud other than that its easy to upgrade firmware and prints well once its calibrated, the probe is a bit crappy ill be designing something to actually hold it

As everyone else points out the instructions are horrendous and the video is not much better. It is a relatively straight forward build(I've never built a 3d printer before.. So it really can't be that bad right?) the hardware and extrusions all seem to be of good quality. The main board is a makerbase mks gen l 1.0 which is from what I can tell a solid board. The steppers are generic and work fine. The powersupply is also generic, but is LOUD it rattles and the fan is rediculously loud. The stock firmware gave me many headaches even though it was marlin firmware it was still horrendous. I updated to 1.1.9 bug fix and was blown away with the difference. I was able to calibrate on the new firmware with ease. I was able to print a test cube and it printed well, however my hot end decided that it wouldn't stay hot after that so I haven't been able to print anything else. Trying to print at 210 and it will heat up slowly but can't hold them temp and drops down until I get a thermal runaway. I've ordered a new heater which should fix the issue.After getting the new heater, I was able to make an awesome print. It has great accuracy and prints very well.The second print I attempted the power supply popped. It blew out the suppression MOV. I attribute this to cheap parts. I ordered a new replacement with fan control and such.Overall I would still have bought this printer, but would be ready to swap parts out.

The components are all of very good quality, and the tools included were of a better quality than I was expecting. All the parts fit together straight and tight.Yes, the documentation is weak (common complaint). But the video assembly instructions offered, as well as the internet in general filled in the gaps on how to assemble this printer quite nicely. I finished my assembly in about 6 hours.My control board had the Marlin firmware preinstalled, but the documentation gave me the impression that the Repetier firmware was what would be loaded. You might want to check the "printer info" in your slicing program to avoid the confusion I had.I had no issue getting the printer to power on, connect to the PC, or to get the firmware updated.Calibrating this big printer was a little tricky, but the instructions that people like Maker Steve have on the internet are very helpful. Maker Steve's calibration spreadsheet is a must have to simplify your calibration method!My first attempts to print were a little frustrating, because the hot end kept jamming. I found that 75mm of heat resistant tubing inserted into the heat sink solved this problem for me completely.After that, this printer has been working without hiccup! It's reasonably fast and surprisingly accurate.Overall, I can't complain. It's a good, huge printer for a very low price!
