Printer: Any

Github

https://github.com/kevinakasam/ERCF_Filament_Cutter

Config

1. Add [include mmu/addons/mmu_erec_cutter.cfg] to your printer.cfg
2. Edit mmu_erec_cutter.cfg and mmu_erec_cutter_hw.cfg to work with your setup

Blobifier

An addon used to create purge blobs instead of using a wipe tower

Compatibility

MMU: Any
Printer: Voron v2, others in the works

Github

https://github.com/Dendrowen/Blobifier

Config

1. Add [include mmu/addons/blobifier.cfg] to your printer.cfg
2. Edit blobifier.cfg and blobifier_hw.cfg to work with your setup
3. Set variable_user_post_load_extension : "BLOBIFIER" in mmu_macro_vars.cfg
4. Optionally set variable_user_post_form_tip_extension : "BLOBIFIER_PARK" in mmu_macro_vars.cfg to park the nozzle on the tray during a swap. Note that it is always recommended that you at least z-hop on toolchange so that the toolhead is immediately lifted off the print. Read Toolchange Movement for more details.

Important

For all add-on extensions, ensure that you always use the "cfg" files from Happy Hare and not those sourced elsewhere so you have the most recent changes and fixes.
