SV08 Beacon/Cartographer Install Guide

EDIT 10/24: Added cartographer instructions and noted specific changes compared to beacon

This is only an installation guide. if you need a mount this is the one i used by PropFortress: https://www.printables.com/model/970499-sv08-beacon3d-rev-h-mount

This guide will be referencing the official beacon3d documentation. We will be configuring beacon contact, but if you want to just use proximity and saved z offset refer to step 7 at the very end. I'm not responsible for any damage this causes and please double check each step by referencing the official documentation.

Please keep these open in another tab as the guide references specific steps

https://docs.beacon3d.com/quickstart/

https://docs.beacon3d.com/contact/

Cartographer Docs: https://docs.cartographer3d.com/cartographer-probe/installation-and-setup (this will take you to the survey setup which taps to set auto z offset)

To get your device ID, SSH into the printer and run the following command: ls /dev/serial/by-id/*

Install guide:

1. After mounting and plugging beacon into the usb on the side of the printer, complete steps 3 and 4 in the quickstart guide.
2. Use winscp or another ftp program to hide the default sovol scripts by navigating to /klipper/klippy/extras and creating a new hidden folder called .sovol (include the . it's what makes the folder hidden)
   • put the z_offset_calibration.py and probe_pressure.py into the newly created hidden folder
3.  Update your printer.cfg by commenting out the following

• [safe_z_home] (we define this in the beacon section) 
  • *If using Cartographer probe you need to keep this in your config*
    • [safe_z_home]
      home_xy_position: 175,175
      # Example home_xy_position: 175,175 - This would be for a 350 * 350mm bed. 
      z_hop: 10
• [probe]
• [probe_pressure]
• [homing_override]
• [z_offset_calibration]
• [adxl345] & accel_chip:adxl if you want to use beacon for accelerometer (rev. H only)

1. Add the following to your printer.cfg. This is what i use for my sv08. please double check it before adding it to yours.

1. Next we will need to update our print start macro in sovol-macros.cfg. I am using the better start print macro by jontek2: https://github.com/jontek2/A-better-print_start-macro and have incorporated the beacon contact workflow. I also have KAMP installed and am using the line purge from KAMP. if you do not have KAMP you can install it from here: https://github.com/kyleisah/Klipper-Adaptive-Meshing-Purging if you don't want to use KAMP you can remove the line_purge part and uncomment the purge line that's commented out. 
   • There is a gcode offset that is added at the end to help for any thermal expansion. Adjust this line/comment out as needed: SET_GCODE_OFFSET Z=0.08 ; add a little offset for hotend thermal expansion 
   • CARTO USERS USE THIS VERSION OF THE MODIFIED MACRO: https://docs.cartographer3d.com/cartographer-probe/installation-and-setup/touch-installation/print-start-macro 
     • Uncomment the following 4 lines for QGL and change the nozzle from 150 to 145

•     Save config and firmware restart to ensure everything is being applied. We'll still need to calibrate beacon by doing the following.
  • home the machine in x and y 
    • G28 X Y
  • Position the machine in the center of the bed
    • G0 X175 Y175
  • Start the auto calibration process
    • beacon_auto_calibrate 
  • Save config
    • save_config
• If using carto, follow setup based on this page: https://docs.cartographer3d.com/cartographer-probe/installation-and-setup/touch-installation/calibration

     7. Now you're ready to start printing! with the current configuration it creates a new z offset at printing temp. If you want to use the beacon_auto_calibrate and save the mesh. comment out the below lines in the print_start macro. If doing this, make sure to run beacon_auto_calibrate at printing tempratures.
