Printer

Prusa XL 5T

How to reproduce

(1) Set up a multi-tool print.
(2) Under printer and/or filament settings, set general retraction to 0.

Under Printer Settings, select your extruders, scroll down to setting Retraction when switching material:

(3) Set Length to any value above 0 (in this case its 20 mm).
(4) Set Extra Length on Restart to any value above 0 (in this case its 4mm).

Actual results

De-retraction after tool change will not include the Extra Length on Restart value. The problematic line of gcode is : G1 E20 F1200

Expected results

De-retraction code should be G1 E24 F1200. Specifically, de-retraction after tool change should be:

Retraction when switching material (Length) = 20

PLUS

Retraction when switching material (Extra Length on Restart) = 4

For a total of 24mm.
