Enough talking !Let’s start making !
Go to:https://github.com/MincheeLab/MakeYourOwn3DPrinter/blob/master/doc/index.md
What you will need
● Acrylic frame: 3 parts● 5 step motors● 1 heated bed● 1 bag of printed plastic parts● 1 set of electronic: Arduino + RAMPS● 1 set of mechanical parts + cables● power supply● rods...find out ;-)
You did make a 3D Printer ;-)
Congratulations!

Motor power
● measure the DC Voltage● around 1.5V ~ 1.7V● if not, rotate clockwise
3D Printer best friends...
How to mess up with your printer ;-)
● Filament in/out - always @hot temperature
● Bed leveling - enjoy the fun ;-)
● Hot-end jammed● Extruder temperature - depend on material quality too...
● Room temperature
Printing Tips & Tricks
before reaching this quality...lot of fails...
