Updating your printer.cfg
Upon installing OpenNept4une, you'll receive the most current version of printer.cfg. This is occasionally refreshed with new features and therefore requires periodic updating to get the latest configurations & macros.
During the initial setup of OpenNept4une, accessible via this Wiki, you'll conduct several calibrations detailed on the Printer Calibration page. Essential settings such as bed_mesh, z_offset, PID tuning, and input_shaper are automatically saved at the end of your printer.cfg under the SAVE_CONFIG section, which looks like this:
#*# <---------------------- SAVE_CONFIG ---------------------->
These settings are commented out (#) in the main body of the printer.cfg file so Klipper actively uses your SAVE_CONFIG values. This approach ensures your calibrated values are separated and prioritised from the main body of the printer.cfg, a standard practice in Klipper.
- Access your printer via
SSH. - Execute the
opennept4unecommand. - Choose
Option (1)to install the latest printer configuration. - You may skip additional config & dtb.
The update process automatically backs up your existing printer.cfg as backup-printer.cfg.bak in the same directory, with subsequent backups numbered sequentially. It then integrates your previous SAVE_CONFIG settings into the new printer.cfg file, ensuring your calibrated data is preserved through the update.
If you want to implement your own, additional macros. Please paste these into user_settings.cfg. The macros listed here will never be overwritten during a configuration update.
