This is a long video.
I just wanted to document some of the assembly problems I encountered so others might benefit from my errors. I ordered this 2017 upgraded prusa clone version with the ATmega 2560 integrated control board from eBay seller ink-top in Los Angeles. The generic brand is CTC. The instructions, in the form of a pdf file, is not the easiest to follow so there's a bit of trial and error. You need to decompress the RAR files on the CD before you can install the Cura software to your computer. The Cura software is not the latest and is in Chinese.
This kit comes with 1 spare corner bracket and 1 motor mount bracket. Most of the parts are pre assembled unlike some of the other kits I've seen on Youtube.
The integrated control board has 4 plugged in stepper driver motor drivers. Since 3 D printers need to run for hours to print something, the drivers can overheat and cause problems. Plug in drivers are better than ones soldered to the board.
Initially, I could not get the right dc voltage from the 15A power supply. The power supply is on 220v by default so you have to find the switch and switch it to 110v before you check it. Cheap power supplies often fail and come doa. I can understand the default voltage set to 220v as a 110v power supply plugged into a 220v by mistake would immediately be damaged. There's trim pot where you can adjust the DC voltage. I set it initially to 12.3v.
I neglected to use some of the washers included in the kit. They certainly would help in preventing the screws from vibrating loose.
I'm sure I'll make more mistakes so that'll be good material for making another video.
