Hi guys, thanks for your fantastic work!
I received my kit a few days back and immediately tried to assemble all the parts. I have assembled a few kits and this is not the worst, but being the previous build a Prusa original MK3, the bar was very high.
First thing I noticed is that there are a lot of parts that are not classified or identified. Also the quality of the metal parts like the brackets for the Z axis is not very good. I think that they are too thin, the same for the screws for attaching this machine seem too thin and would prefer to see M5 or M6 (which are easier and cheaper to buy).
The building instructions are not terrible but need some work and organization in the website.
When trying to upload the firmware to the Arduino board I had some trouble, you can improve that step just preloading the latest firmware. Takes some time, but I think that it could be well spent from the user perspective.
Instead trying to order them from China and pay in advance and all this trouble I would suggest to look for local suppliers/partners in Europe, USA, etc. Shipping all this weight of screws and chains seems not an intelligent thing since it can be found in any local hardware store. The same for screws, bolts and the such. And then you could concentrate your money and time in buying the special bits that are custom made for you like: motor shield and the motors, cables and that’s all. Maybe designing some parts to be 3D printed could help to make it easier to build locally?
Still not have builded the frame because I have no space, but looking for some partnership with a local maker. We also want to build something that can be easily disassembled and put aside.
One last advice: Being the cheapest cnc is a good add but anyone in China can make it cheaper than you.
