This document describes the process of running Klipper on a Beaglebone
|
||
|
|
PRU. The PRU support is experimental.
|
||
|
|
|
||
|
|
Building an OS image
|
||
|
|
====================
|
||
|
|
|
||
|
|
Start by installing the
|
||
|
|
[latest Jessie IoT](https://beagleboard.org/latest-images) image
|
||
|
|
(2017-03-19 or later). One may run the image from either a micro-SD
|
||
|
|
card or from builtin eMMC. If using the eMMC, install it to eMMC now
|
||
|
|
by following the instructions from the above link.
|
||
|
|
|
||
|
|
Then ssh into the beaglebone machine (ssh debian@beaglebone --
|
||
|
|
password is "temppwd") and install Klipper by running the following
|
||
|
|
commands:
|
||
|
|
```
|
||
|
|
git clone https://github.com/KevinOConnor/klipper
|
||
|
|
./klipper/scripts/install-beaglebone.sh
|
||
|
|
```
|
||
|
|
|
||
|
|
Install Octoprint
|
||
|
|
=================
|
||
|
|
|
||
|
|
One may then install Octoprint:
|
||
|
|
```
|
||
|
|
git clone https://github.com/foosel/OctoPrint.git
|
||
|
|
cd OctoPrint/
|
||
|
|
virtualenv venv
|
||
|
|
./venv/bin/python setup.py install
|
||
|
|
```
|
||
|
|
|
||
|
|
And setup OctoPrint to start at bootup:
|
||
|
|
```
|
||
|
|
sudo cp ~/OctoPrint/scripts/octoprint.init /etc/init.d/octoprint
|
||
|
|
sudo chmod +x /etc/init.d/octoprint
|
||
|
|
sudo cp ~/OctoPrint/scripts/octoprint.default /etc/default/octoprint
|
||
|
|
sudo update-rc.d octoprint defaults
|
||
|
|
```
|
||
|
|
|
||
|
|
It is necessary to modify OctoPrint's **/etc/default/octoprint**
|
||
|
|
configuration file. One must change the OCTOPRINT_USER user to
|
||
|
|
"debian", uncomment the BASEDIR, CONFIGFILE, and DAEMON settings and
|
||
|
|
change the references from "/home/pi/" to "/home/debian/":
|
||
|
|
```
|
||
|
|
sudo nano /etc/default/octoprint
|
||
|
|
```
|
||
|
|
|
||
|
|
Then start the Octoprint service:
|
||
|
|
```
|
||
|
|
sudo systemctl start octoprint
|
||
|
|
```
|
||
|
|
|
||
|
|
Make sure the octoprint web server is accessible - it should be at:
|
||
|
|
[http://beaglebone:5000/](http://beaglebone:5000/)
|
||
|
|
|
||
|
|
|
||
|
|
Building the micro-controller code
|
||
|
|
==================================
|
||
|
|
|
||
|
|
To compile the Klipper micro-controller code, start by configuring it
|
||
|
|
for the "Beaglebone PRU":
|
||
|
|
```
|
||
|
|
cd ~/klipper/
|
||
|
|
make menuconfig
|
||
|
|
```
|
||
|
|
|
||
|
|
To build and install the new micro-controller code, run:
|
||
|
|
```
|
||
|
|
sudo service klipper stop
|
||
|
|
make flash
|
||
|
|
sudo service klipper start
|
||
|
|
```
|
||
|
|
|
||
|
|
Remaining configuration
|
||
|
|
=======================
|
||
|
|
|
||
|
|
Complete the installation by configuring Klipper and Octoprint
|
||
|
|
following the instructions in
|
||
|
|
[the main installation document](Installation.md#Configuring_Klipper).
