"Extra length on restart" setting is ignored

[Smartnitz]

OrcaSlicer Version

1.8 beta2

OS version

Windows 11

Additional system information

No response

Printer

Bambu Lab P1P

How to reproduce

1. Slice the Cube Primitive model
2. Change "Extra length on restart" value either in the "Printer>Extruder" Settings or the Filament>"Setting Overrides" Setting
3. Check the G-Code for any layer: In the very first line for each layer the extruder is supposed to unretract filament. Check the unretract length value in the G-Code

Actual results

Whatever "Extra length on restart" is set to is ignored. It is only unretracting the regular retract length.

Expected results

"Extra length on restart" value should be added to the regular unretract length.

I just checked it in OrcaSlicer 1.7 and it has the same issue. Last version the feature was working is 1.6.6

The bug is still present in the final Version 1.8 :(

I noticed that this bug is related to the "wipe while retract" setting. Turning this off also fixes the issue with the "extra length on restart" setting. Still hoping for a fix soon, since both settings are really important for me

found the temporary fix here:

Yes, confirmed

Candidate fix here: #3065

please test and come back with observations.

PS. you shouldn't need extra length for restart with the P1P/S and your retraction value in the attached file is too high (0.8 is good for a P1X/X1C printer) but I assume you're doing that to demonstrate the bug.

The fix solves the problem and has worked perfectly for me so far.

Thank you so much <3

The setting is very practical for some filaments that virtually suck themselves back into the nozzle when retracted.
I use 0.4 mm retraction + 0.1 mm extra. The values from the screenshot are for demonstration purposes only.
