dwc2-for-klipper-socket

This is a rewrite of dwc2-for-klipper. As Klipper offers now a unixsocket API, its time to use it and run outside klippers main thread.

Things you should know

• It works everywhere where klipper works, not only with duet boards
• Klipper is not RepRapFirmware
• This is a translator between klipper and Duet Web Control
• The DWC service can be restarted at any time without restarting klipper
• Sometimes buttons get a bad response - especially macros
  • Usually a timing issue
  • Make sure action gets performed
  • Set AJAX retries to 0 for now:
  • Settings > Machine-Specific > Number of maximum AJAX retries
• There is a configfile now
• Klipper's printer.cfg is displayed as a virtual file (config.g) in system section
  • Restart after configuration edits works
• The macros you define in printer.cfg are displayed as virtual files wthin DWC's macros/klipper folder
• For pause and resume macros you can use:
  • Klipper gcode macros pause_print, resume_print, cancel_print (not case sensitive)
  • DWC macros pause.g, resume.g, cancel.g - this is in line with RRF
  • DWC macros are overriding Klipper's macros
