Just bought my first issue (No.1) of Robi magazine at 7‑Eleven convenience store, if you live in Hong Kong you can subscribe it online, I already re-order the issued magazines (No.2-5 issue) & made a subscription as well.

RepRap DIY 3D Printer

My first blog, wanna build a 3D printer myself for a long time, been gathering information, sourcing the parts that may needs, I already got most of the main component in stock but still deciding how to build the frame of the 3D printer, probably using the V-Slot aluminum extrusion. I' am recently start selling the parts on my eBay store as well, just in case anyone need it and it went quite well, thanks for the support! Will update from time to time! Any idea, suggestion please leave me a message. Good day!

Ideas for better 3D printer?

1. Multi Color & material with single extruder? Mosaic Manufacturing came up with a solution to turn your machine into a multi-colour 3D printer.
2. Multi nozzle diameter with single extruder?
3. Print Bed Auto calibration
4. Affordable (Reasonable price)
5. Require less (Easy) maintenance
6. Expandable so you can upgrade your printer in the future
7. Keep the structure as simple as possible  (MakerGear M2 & Printrbot Metal Plus did a great job)
8. Can be use with laser engraving & CNC router as well
9. Faster Printing time

Software

     1. Arduino IDE

• Program that needs to upload Marlin (firmware) to your arduino mega 2560 main board

     2. KISSlicer

• Program that takes 3D files (STL) and generates G-code for your 3D Printer

     3. Printrun

• Program that runs the G-code from the KISSlicer & control your printer movement in order to print out your part

Code

1. Ramps1.4 Arduino Stepper Motor Test Code
