M208 - Firmware Recover Settings

motion Set firmware-retraction recover settings. FWRETRACT

Description

Set the added lengths and feedrates 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.

Send M208 with no parameters to get the current firmware-based retraction recover settings.

Tuning the values

See M207 for helpful G-code files and tips for tuning retract and recover.

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
