Great machine, super fast 3D printer. Assembled in 3 hours. Good point : stl files provided to print some parts of the printer in case one is broken.

You should use this startup gcode (you can change it in Repetier/Cura settings) : ; Default start code G28 ; Home extruder G29 ; Auto calibrate printhead G1 Z15 F9000 M107 ; Turn off fan G90 ; Absolute positioning M82 ; Extruder in absolute mode ; Activate all used extruder M104 T0 S195 G92 E0 ; zero the extruded length ; Wait for all used extruders to reach temperature M109 T0 S195 ; Purge nozzle G1 E19 F200 ; purge nozzle quickly G1 E26 F60 ; purge nozzle slowly G92 E0 ; zero the extruded length again

Got the printer within two weeks of order placement. Printer kit is complete. Instructions are photographic with minimal text. Sometimes the text showed parts in different places. Also a few instructions are out of sequence towards the end of assembly.

Be sure and use the USB stick that comes with the printer to configure Marlin. Very good settings. My first test print worked out well with the default settings after I did the calibration steps in the manual. I took about 8 hours to assemble and 5 to calibrate.

This is my first 3D printer. Much like Ikea you must pay attention to the details and orientation of the parts. Be patient and take your time. Good luck with yours.

I own 2 3D printers already and this is my 3rd one. I have a lot of experience in assembling and using these printers. This metal structured 3D printer came as a surprise as I found it more stable and it has improved printing accuracy. This printer is technologically advanced and consists of automatic platform levelling and height detection and Heated Print Bed + Switch Power (+$34 USD). It’s unbelievable to get such advanced and high functionality printer at such an economical price. Happy to have it!

For a novice like me who had no previous experience in 3D printing, Kossel came to my rescue as I had only 4 days to submit the replicas of ‘museum artifact’ as a project to my history teacher.

This printer is cost-effective and supports PLA, PVA, Wood and Nylon filaments. Do check the diameter of the filling. Mine wasn’t sturdy! The Metal frame structure makes it look beautiful.

The Integrated main board was easy to assemble. Thanks to the detailed manual!  All in All I give this printer a heart-warming 4 stars!!!

The printer was delivered safely and quickly, the printer came with a spotty LCD which was replaced by the customer services team.

I assembled the printer quickly and forgot to do a quality check on my work; I got a few bad prints and then realized the slide rails were loose.

I was still getting a lot of plastic wrapping issues which were solved by using a glass build plate. The auto bed levelling and auto calibration works wonderful. The arms that hold the nozzle works smoothly and I feel they are world class quality.

I have made some nice multi-color prints using pla and the printer also got some decent prints with Nylon.
