Wizard info page: Plus4 - Phil1988/FreeDi GitHub Wiki

This page will provide helpful information to prepare for the toolhead update process.

By following the wizard, you will be flashing the toolhead to the new klipper firmware version. This is an essential step to ensure compatibility with the new klipper version that FreeDi uses.

Make sure that you have attached the ST-Link V2 your printer's USB port and the toolhead. If you are unsure how to do this, you may have skipped this mandatory step for your Plus4: https://github.com/Phil1988/FreeDi/wiki/Step-%232:-Flashing-the-toolhead-(Plus4)

Once you have completed this, proceed with the next 2 steps:

Step #1: Flashing the katapult bootloader

This step is fully automatic. The wizard will flash a precompiled katapult bootloader that FreeDi provides. With this bootloader, you will not need to use the ST-Link V2 for future klipper updates.

Just click the "Install" button in the on-screen wizard, and it will do this for you. If anything goes wrong, the wizard will report this back.

Step #2: Flashing the klipper bootloader

The second step is semi-automatic.

  1. Locate the the reset button on your toolhead. image It might look different for your toolhead, as different revisions have been installed in the machines.

  2. Double tap the "reset" button.

This process will request katapult (the bootloader we have just installed) to go into boot mode. In this mode, it is possible to install klipper. Just click the "Install" button in the on-screen wizard to do this for you. If anything goes wrong, the wizard will report this back.
