Custom 3D Printer with Arduino MEGA2560 and maybe a Raspberry Pi?

[TheCoder2019]

So, I got into 3D CAD about a year ago, and I now want to print some of them out. So I have a 12x12 inch plate of aluminum, and an Arduino MEGA2560. Instead of being a normal Human and buying a prebuilt 3D Printer, I want to DIY one. Can someone generate a BOM with a budget of $150 USD?

 

NOTES:

Prints ABS and PLA Filament

Supported file types are OBJ and STL

Supports USB Devices like a flash drive

Can read more than 1 file at a time

Print quality is very good, and precise

 

Any help and advice is appreciated!

I would probs just go the RAMPS route with octoprint  I think you'll struggle with that budget personally

No one uses a bog-standard Arduino for such. You need a lot of extra circuitry even just for driving the stepper-motors and using an Arduino with those plastic connectors will just introduce a ton of headaches. You need a power-supply, you need a way of controlling current flowing into the extruder and the heatbed, you need overcurrent- and overvoltage-protection and so on.

 

Cobbling everything together by yourself is certainly possible, but unless you have access to a very good selection of electronics to salvage from, you won't be getting to your $150 target with any good quality. Shit quality? Sure, that's doable.

Old 3d printers commonly used a mega with the ramps 1.4 shield. It works fine, but the mechanics of a printer is way harder and will probably cost you more than just $150. I’d spend the extra $100 to get an ender 3

Do not build your first printer, buy something that works. Just my 2c, but I've been doing this for a looooong time and you'll find yourself up a creek with little/no documentation/forum help to fall back on.
