A translator between DWC2 and Klipper

• printing from klippers virtual sdcard
• pause / cancel prints (resume?)
• babystepping feature using klippers SET_GCODE_OFFSET Z_ADJUST
• editing klippers configuration. Its displayed as config.g in system section. So the webif restarts klipper after saving.
• Klipper macros are imported as virtual files and can be accesed from the dashboard
• uploads and downloads of gcodes
• gcode analysis using regex to determine duration / layerhighth / firstlayer / filamentusage and other
• the math for printtime left based on whatever, showing layerhistory, detecting layerchanges etc. (needs working slicer regex)
• settings of webinterface are saved and loded correctly
• homing / extruding / moving
• heater control
• setting fanspeed / extrusionmultipler / speedfactor during print in statuswindow
• Heightmap is working. (needs manual BED_MESH_CALIBATE) It is kept only for displaying, even after BED_MESH_CLEAR
• webcam integration works now
  • with mjpeg-streamer add the streaming url to settings. example: http://192.168.2.20:8080/?action=stream
  • With youtube live https://webcam.io/support/howto-embed-youtube-live/
• pause/resume/cancel macros are working now - see Things you should know
• plugin for Cura 4.0 does work, just enter url for example: http://192.168.2.188:4750/

• webcam integration
• heightmap
• printsimulation
• actual machinespeed, only displaying the requested values
  • klipper does not have this feedback (yet)? due to its lookahead feature
  • can we calc this? movelength/junction/acceleration is there
• cancel/pause/resume macros. I will do this soon
• rrf/dwc cura plugin
• ......

• Klipper messages are marked as warnings.(yellow)
  • Noramly klipper knows ok and error
• Klippers printer.cfg is displayed as a virtual file (config.g) in System section
  • restart after conf edits works
• The macros you define in printer.cfg are displayed as virtual files wthin DWCs macros
• For pause and resume macros you can use:
  • kliper gcode macros pause_print resume_print cancel_print (not case sensitive)
  • dwc macros pause.g resume.g cacnel.g - this is in line with rrf
  • dwc macros are overriding klippers
• ....

python2, tornado, gunzip, unzip, wget

sudo pacman -Sy && pacman -S python2 python2-tornado wget gunzip

Maybe you´ll need to change the startup system for klipper to access ~/klipper/klippy/klippy.py

I asume here that you used the octopi install script from Kevins github.

sudo apt install wget gzip tar

Then switch to your klipper user and:

sudo systemctl stop klipper
cd ~
mv klipper klipper_backup 
PYTHONDIR="${HOME}/klippy-env"
virtualenv ${PYTHONDIR}
${PYTHONDIR}/bin/pip install tornado==5.1.1

git clone https://github.com/KevinOConnor/klipper.git
git clone https://github.com/Stephan3/dwc2-for-klipper.git
ln -s ~/dwc2-for-klipper/web_dwc2.py ~/klipper/klippy/extras/web_dwc2.py

mkdir -p ~/sdcard/dwc2/web
mkdir -p ~/sdcard/sys
cd ~/sdcard/dwc2/web 
wget https://github.com/Duet3D/DuetWebControl/releases/download/3.1.1/DuetWebControl-SD.zip
unzip *.zip && for f_ in $(find . | grep '.gz');do gunzip ${f_};done
sudo systemctl start klipper

cd ~/sdcard/dwc2/web 
wget https://github.com/chrishamm/DuetWebControl/releases/download/1.22.5/DuetWebControl-1.22.5.zip
unzip DuetWebContro*.zip
for f_ in $(find . | grep '.gz');do gunzip ${f_};done
