Linux

simreprap

1. Install dependencies

   sudo apt-get install libdevil-dev libtool-bin libtool libfontconfig1-dev clang libelf-dev freeglut3 freeglut3-dev gcc-avr avr-libc gcc make git libcairo2-dev picocom
   

2. Clone repository

   git clone https://github.com/buserror/simreprap

3. Compile

   cd simreprap
   make -I shared/libc3/

4. Run

   export SIMAVR_UART_XTERM=1
   obj-x86_64-linux-gnu/reprap.elf

Pronterface

1. Install dependencies

   python-wxgtk2.8 is required and is not available in the Ubuntu 16.0.4 repositories.

   sudo add-apt-repository ppa:nilarimogard/webupd8
   sudo apt update
   sudo apt install python-serial python-wxgtk2.8 python-pyglet python-numpy cython python-libxml2 python-gobject python-dbus python-psutil python-cairosvg
   

2. Clone the stable branch for Printrun

   git clone -b stable https://github.com/kliment/Printrun

3. Run

   cd Printrun
   python pronterface.py

tty0tty

This project will setup virtual COM ports, which is what 3D printers communicate through.

1. Download

   git clone https://github.com/freemed/tty0tty

2. Build

   # build
   cd tty0tty-1.2/module
   make
   
   # Copy the new kernel module into the kernel modules directory
   sudo cp tty0tty.ko /lib/modules/$(uname -r)/kernel/drivers/misc/
   
   # Load the module
   sudo depmod
   sudo modprobe tty0tty

3. Test / set permissions You should see new serial ports in /dev/ (ls /dev/tnt*) Give appropriate permissions to the new serial ports

   # list new COM ports
   ls /dev/tnt*

   

   # setup permissions
   sudo chmod 666 /dev/tnt*

   You can now access the serial ports as /dev/tnt0 (1,2,3,4 etc) Note that the consecutive ports are interconnected. For example, /dev/tnt0 and /dev/tnt1 are connected as if using a direct cable.

4. Make tty0tty persistent

   # edit modules
   sudo vi /etc/modules
   
   # add this line
   tty0tty

picocom

Install picocom to see traffic over COM port

1. Install

   sudo apt-get install picocom

2. Use

picocom /dev/tnt0

simavr

1. Build

   simavr

   git clone https://github.com/buserror/simavr.git
   cd simavr
   git checkout tags/v1.4

2. Run

   ######### TODO ######## We need to add steps for running and opening a virtual com port

simutron

######### TODO ######### ######### DOES NOT WORK #########

simutron is not required. It only provides a GUI around simavr

1. Download and extract

   # download
   wget https://sourceforge.net/projects/simutron/files/Simutron-1.0.1/Linux/simutron-1.0.1-SR1-Linux-x86_64.tar.gz
   
   # extract
   tar -xvzf simutron-1.0.1-SR1-Linux-x86_64.tar.gz
