This is my third 3d printer and overall I like it. But there are things others should consider before choosing it as a project.
I have been using it for the last week and it is growing on me. Once the stops are adjusted and the bed is leveled it works flawlessly.
I picked this printer because it was cheaper and faster then ordering the pieces separately.
I ordered it from MatterHackers and it was shipped from Velleman in Texas (USA). It arrived in about 3 days with standard shipping. The packing was very good, The inner box alone would probable have been OK. Sorry about no unboxing photos but I had not intended to write this at the time. Most of the parts are in clearly marked bags the others are east to identify. The injection molded plastic parts are excellent quality.
The assembaly instructions are better written then most, Almost as good as Heathkit was. A lot of the stress was pulling the 90 deg brackets out so I could correct something.
The first and biggest problem are the 90 Deg. brackets. It comes with 20 but you only need 14 (and could easily cut that down to 12) These brackets will need lots of work before you can use them. you will need to be able to slide them along one extrusion while holding another at 90 degrees. 5 pair need to make a perfect 90 deg angles. Spend the time to test fit them and sort out the most perfect pairs and the rest of the build will be a lot easier.
The second thing was that bag #26 had the wrong setscrew in it. Don't panic, the screw is in bag 28.
Leveling the bed is a pain but exact. The rest of the assembly nits i picked where:
The instructions should have you wire the limit switches before mounting. The end stop wire is Orange not Red. I ran out of the small heatshrink(some nits are smaller then others) The bed thermistor wires are Red Brn not Blk Wht.
I love the last line in the assembly instructions "Make sure to read and understand these next chapters, because they contribute a whole lot to the printing quality of the K8200." The User manual that is referenced on the MaterHackers site is about converting the K8200 to a milling machine.
The information you need to set it up can be found here: http://www.k8200.eu/manual/printing. You will need at least 3 hands excellent eyesight and a very tiny non-conductive screwdriver.
The instructions assume you are using Repetier but after half a day I switched to MatterControl and its been farily smooth since then. I'm still in the tuning stages. My preferred toolpath is Slic3r using Repetier as a front end and g-code viewer and build plate filler on my desktop computer and transferring the g-code to my printing computer. (Not 3DSlicer A viewer for MRI's and other 3d medical images.)
Repetier Patched as i was writing this and i haven't tried the new version. Now i just drop the .stl in MatterControl and come back when it is done.
I feel I got a good value for money. If it had better 90 deg. brackets I would not hesitate to recommend it. But with the extra elbow grease you end up with a lot for your money. Also note it is a kit for the 3drag RepRap.
( Before Johnny Storm asks I didn't see a way I could post this under reviews since I am not an official "reviewer".)
