PanelPi

Raspberry Pi control panel for DuetWifi

Work In Progress

Releases

Beta 2

28/11/2018 - Beta 2 release!
Releasing latest binary from master branch, include working GCode view and some bug fixes. Not much development recently, will spend more time on it during Christmas holidays.

Beta 1

08/07/2018 - Beta 1 release!
PanelPi is now in a usable state, however, only printer with XYZ axes and 1 hotend is supported, it was tested on a Core XY setup with a single hotend.

Why PanelPi?

The main motivation of starting this project is I want a control panel for my DuetWifi with a better UI and touchscreen then PanelDue.

How is this better then PanelDue or duet web interface?

• Better UI :)
• Better touch experience with Raspberry Pi's capacitive touchscreen
• No wifi disconnect / javascript issues

How is it worse?

• Long boot up time, RaspberryPi + JavaFX start up time can take from 30 seconds up to a minute.
• It consume more power

PanelPi is not a money saving solution to PanelDue, RaspberryPi + official 7" screen is not much cheaper

Setting up Panel Pi

Prerequisite

• Raspberry Pi 3
• Official Raspberry Pi 7" touchscreen

Hardware setup

The 5v output from the Panel Due port might be a little under voltage, which will trigger RaspPi's under voltage warning, it's better to get power directly from 5v PSU if possible.

Software setup

1. Flash RASPBIAN STRETCH Lite to your SD card

   • https://www.raspberrypi.org/downloads/raspbian/

2. Setup raspberry pi wifi and ssh

   • https://www.raspberrypi.org/forums/viewtopic.php?t=191252

3. SSH into RaspberryPi

4. raspi-conf

   • memory split - 128mb
   • enable serial port
   • hostname
   • console auto login

5. apt-get update/upgrade

6. install java

   • sudo apt-get install oracle-java8-jdk

7. install javafx

   • https://lb.raspberrypi.org/forums/viewtopic.php?t=146098#p1009599

8. install wiringpi

   • http://wiringpi.com/download-and-install/

9. install xorg

   • sudo apt install xorg libgtk2.0-0

10. Run Panel Pi

    • sudo java -Dprism.order=sw -Djava.ext.dirs=/home/pi/jdk1.8.0_92/jre/lib/ext/ -jar panelPi.jar

TODOs

• Console view - command hint and validation
• Stop mimicking duet web interface and optimise UI for small touchscreen
• Webcam support?
• Multi-hotend/Tool support
• More detailed step-by-step setup instructions
• Splash screen
• Use raspberry pi as a second SD card slot? (Is it possible?)
• improve startup time
• Edit list items in setting
• Developer docs
• Raspberry Pi image for easier setup
• UI for other screen resolutions?
• Port to android?
• Custom CSS

Why JavaFX, Kotlin?

• Easy to mimic duet web interface's look and feel using CSS
• Possibility of porting to android
• Easy to write compact code quickly

Known Issues

• Slider is difficult to use
