Very slow speeds for retraction during wipe

[black_jack53]

I have a problem with the retraction during wipe setting.
If I tick the boxes under the advanced tab as shown in the picture(link)
https://www.dropbox.com/s/ptsp2z75a456w ... 6.png?dl=0
the prinhead will stop at a certain point while printing a benchy and filament will drool out of the nozzle. I found the problem within the gcode S3D is creating:

Code: Select all

; solid layer
G1 X83.969 Y102.297 F6000
G92 E0
G1 X83.954 Y102.282 E0.0003 F1751
G92 E0
G1 X83.969 Y102.297 E-8.0000 F5
G1 Z9.000 F1002
G1 X117.598 Y100.627 F6000
G1 Z8.600 F1002
G1 E0.0000 F1800

The line #30635G1 X83.969 Y102.297 E-8.0000 F5 is causing the problem because filament is retracted by 5 mm/min.
Until the full retraction distance is achieved the printhead will stop moving.

In other models this problem is even worse up intil the speeds dropping to 0 mm/min (F0)...

However if i tick the checkbox for wiping only on mot outer perimeter in the advanced tab i have no issues at all.

Here is also a Link to my Ultimaker FFF profile and the complete gcode of the benchy:

Hope anyone can help me with this issue

Hi,

I have the exact same problem using Simplify3D 4.0.0. This has to be a regression in 4.0.0. I am running the same profile as I did for previous versions and did never have this problem before.

Did you by any chance find a resolution to the problem? I will file a support ticket right away and see what happens.

Here is another piece of Gcode showing the issue. My retraction length is 3.5mm and retraction speed is 45mm/s (F2700).

Code: Select all

G92 E0
G1 X107.878 Y99.958 E-3.5000 F20
