Took 3 days to deliver so no complaints there. I spent an easy 2 days doing the assembly. Make sure things fit smoothly and correct if they don't. It's a lot harder to pull apart latter. Printer worked straight up but I then spent some time calibrating. I now just turn it on and print. For the money it's brilliant and the print quality is amazing.
I've been choosing a delta kit between the linear rails, smooth rods or roller-carriages design - but that appears to be the last thing which may affect the print quality. First you should look on push-rod ball-joints play and equality of their length! Kossel is the cheapest solution - roller carriages, but they work quite well and easily upgradable to linear rails.So I concluded that in case of failure my money loss would be minimal with Kossel Mini.
In fact, after 3 days of assembly and software configuration I finally started the first 3D print in my life (end-stop mount): https://youtu.be/AuJ0LaVsB38
My 2-nd test print was more complex, also not bad: https://youtu.be/x0kJCxQ-pBs
1 star off for the problems with Marlin firmware provided on SD-card (not compillable, with some Chinese characters).
So I've searched for another firmware and transferred configuration settings from original (not a big deal for a software engineer professional, but could be an issue for others).
Printer was sent to Germany by UPS parcel. I had to redirect it to a remote pickup station where I picked it up. Correspondence with the sales team was fast and good. The printer was safely packed and everything was in good shape at arrival. I was very pleased with the complete kit. Everything in it was packed in dedicated boxes, packing list, USB with manual, everything thoroughly labeled. Assembly needed three unhurried evenings. The assembly guide is awesomely detailed! Electrical assembly also was very easy, too. Parts fitted easily together and after no time I was able to print my first parts ever (OK, the hotend holder has some slight problems accepting the M3 nuts, but nothing critical). I reflashed the mainboard with a Marlin firmware modified by "LVD" (reprap forum) which made calibration very easy. So, after all, I´m very happy with the kit and printing with it makes a lot of fun! Thank you for your nice kit, I can recommend it.
I am an extruding machine setter so it was not a problem to assemble the 3D Printer. Also, the manual was quite helpful. I loved the aluminium frame which created good quality prints and it was more stable than the previous plastic framed printer that I bought. And lastly, thanks for those 2 cooling fans because I didn’t face that heating problem again. Recommended!
Wonderful printer kit! I was happy to see that most of the pieces were ABS injection molded and the few 3D printed parts were well done in orange ABS. No parts were missing and there were lots of extra screws and nuts. Although the instructions were in somewhat broken English, the steps and images were easy to follow. I had some questions about first layer nozzle height which they answered right away on Skype. I had a broken thermistor, but I had an extra E3Dv6 which I used instead. When I mentioned this to support they insisted on shipping me a replacement. The printer has been printing quickly and accurately and I believe I made a good purchase!
