# dwc2-for-klipper-socket

This is a rewrite of [dwc2-for-klipper](https://github.com/Stephan3/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](https://github.com/KevinOConnor/klipper) and [Duet Web Control](https://github.com/Duet3D/DuetWebControl)
- 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

### Installation ###

@th33xitus made a installer, see:
[Installer](https://github.com/th33xitus/kiauh)

##### Klipper needs to run with an additional arg ```-a /tmp/klippy_uds``` ####

This is my klipper systemd service located at ```/etc/systemd/system/klipper.service```
```
[Unit]

```

---- todo add /etc/default here ----

Make sure klipper is up and running with unixsocket enabled before next steps.
