Prepare the Raspberry Pi

Follow the instructions to install OctoPi on a SD card.

Tested version:

OctoPrint version	OctoPi version
1.10.0	1.0.0

Default user configuration is:

Username	Password
admin	octopi

Once OctoPi is installed, boot the Raspberry Pi.

Optional: configure network (wifi in /etc/wpa_supplicant/wpa_supplicant.conf).

Install dependencies

First,

sudo apt-get update && sudo apt-get upgrade

Then, install pigpio (see documentation):

sudo apt-get install pigpio

Enable the pigpiod service (auto-start at boot)

sudo systemctl enable pigpiod

Create the 3dpc-software folder and clone this repository:

mkdir ~/3dpc-software
cd ~/3dpc-software
git clone https://github.com/hperchec/3dpc-software.git

Create symbolic link for service

sudo ln -s ~/3dpc-software/service/3dpc.service /etc/systemd/system/3dpc.service

Enable the service

systemctl enable 3dpc.service

Enable hardware PWM

In /boot/config.txt

# Enable hardware PWM
dtoverlay=pwm-2chan,pin=12,func=4,pin2=13,func2=4
