M208 - Firmware Recover

planner Firmware-retraction recover settings. FWRETRACT

Description

Use M208 to set the feedrates and additional lengths for firmware-based retract recovery. The lengths set by M208 are applied in addition to the lengths set by M207 when un-retracting (aka “recovering”) the filament. The new values will apply to all subsequent G11 commands.

The “swap” values apply to firmware-based recover moves after a tool-change.

Notes

Requires FWRETRACT.

See related codes G10, G11, M207, and M209.

Usage

M208 [F<feedrate>] [R<feedrate>] [S<length>] [W<length>]

Parameters

[F<feedrate>]

Recover feedrate (units/min)

[R<feedrate>]

Swap recover feedrate (units/min)

[S<length>]

Additional recover length. Can be negative to reduce recover length.

[W<length>]

Additional recover swap length. Can be negative to reduce the length.

Examples

Set recover extra length to 0.2mm and recover feedrate to 10mm/s

M208 S0.2 F600 

Set a retract length of 2mm and total recover length of 2.5mm

M207 S2.0  ; 2.0mm retract 
M208 S0.5  ; 2.0mm + 0.5mm recover
