Individually adjust speeds for walls, infill, support and more!

Currently works with Cura, please add support for other slicers!

Supported line types:

• infill (TYPE_FILL)
• skin (TYPE_SKIN) (first/last few layers)
• skirt (TYPE_SKIRT) (also brim/raft)
• support (TYPE_SUPPORT)
• wall_inner (TYPE_WALL_INNER)
• wall_outer (TYPE_WALL_OUTER)

If you find more, please add them or open an issue!
Any unknown line types should only result in a warning Unknown command.

This script utilizes the ;TYPE: comment by Cura. The comments are replaced with TYPE_ to make them a macro call.

The macro SET_SPEEDS is called by the user to set the speed for each line type. While printing, the TYPE_ macros set M220 to the corresponding speed.

IMPORTANT: once you set one of the speeds, DO NOT USE M220, neither the speed slider! This macro will overwrite it.

The macro UI of your klipper/moonraker frontend is probably the most intuitive option.
Speeds are in percent!

; to get current speeds
SET_SPEEDS

; to set speeds, e.g. 100% for everything
SET_SPEEDS INFILL=100 SKIN=100 SKIRT=100 SUPPORT=100 WALL_INNER=100 WALL_OUTER=100

; to disable custom speed control and use M220 / speed slider again
DISABLE_CUSTOM_SPEEDS

Include betterspeedadjust.cfg in your printer config. There are multiple ways, I have the file in macros/ and include it with [include macros/*.cfg].

If you don’t already know what to do, download betterspeedadjust.cfg, upload it to your printer’s config directory and include it by putting [include betterspeedadjust.cfg] into your printer.cfg.

In Cura, go to Extensions > Post Processing > Modify G-Code and add a new script Search and Replace:

Search: ;TYPE:
Replace: TYPE_

Add two more after the one above (IMPORTANT):

Search: TYPE_WALL-INNER
Replace: TYPE_WALL_INNER

and

Search: TYPE_WALL-OUTER
Replace: TYPE_WALL_OUTER

Leave regex unchecked for all three.
