Renew3D

A simple, cheap and (hopefully) reliable 3D printer.

What kind of name is this?

I built my first 3D printer a couple of years ago, but there was no assembly, only parts from thingiverse, etc. Then I had an idea to make a new printer with extra features, but the project became waaay to complicated (check it here). So this printer here, is a "renewed" version of those two (quite bad, I know).

Getting Started

The files for this printer are available in .f3d, .step and .stl formats. If you want to assemble the printer, I suggest that you check assembly.f3z (alternatively assembly.step) first, and check what materials to buy and what parts to print. Then look into the printed_parts directory and browse files in different formats. If you have a sensor, board, hotend, etc. check the extras directory.

Firmware Uploading (Linux)

You can use any firmware you like, here is just my example config using Marlin 2.0.x for Ramps board with mega 2560.

1. Download Marlin Firmware here.
2. Install platformio (example on Arch Linux):

   $ paru -S platformio

3. Go to the downloaded firmware directory and replace Marlin/Configuration.h and Marlin/Configuration_adv.h with files from firmware in this repository.
4. Plug in the printer and run:

   $ platformio run --target upload -e mega2560

Note on cheap Chinese boards

Try these steps (stop when you get it to work):

• Install i2c-ch341-dkms from AUR.
• Disable udev rules:

   /usr/lib/udev/rules.d/90-brltty-device.rules
   /usr/lib/udev/rules.d/90-brltty-uinput.rules
  

• Specify upload_port = /dev/ttyUSB0 in ini/avr.ini

Development

Specific Components

If you are creating a new specific part (like SKR 1.3), put it in the extras directory. If it's made of multiple bodies, export the whole file as .f3d and .step. Then export separate bodies (only printable parts) as .stl.

Main Assembly

For main assembly, use only the assembly.f3z when developing. then export the modified printable parts in all formats and put them in main_assembly directory.
