Printer Model: Ender 5 Pro
MCU / Printerboard: BTT SKR Mini e3 v3 klippy.log file too big, 29 mb? is this the root to the whole problem? something nasty happening?
Describe your issue:
Hey guys! Polymer Engineer from sweden here!
What an awsome firmware to begin with! But ive encounter something strange i couldnt fix, i was first using Cura, but to get firmware retraction to work without addons/plugins i switched to SuperSlicer, ive turned of everything i can find that is doing any auto speed thing in the slicer to make Klipper take care of things. X Y movements is really solid and works really good, but the firmaware retraction is working but it retracts so slow!
6mm retraction at 100mm/s speed takes 4-5 seconds, so something is of but i cant find where…
I can uploead klippy to google drive if needed, it was too big for forum, 29mbv ;o
A klippy.log would help since it contains the interpreted config that you are using. You either can zip it, upload it to gdrive.
The settings that limit retraction velocity are:
[extruder]
#max_extrude_only_velocity:
#max_extrude_only_accel:
# Maximum velocity (in mm/s) and acceleration (in mm/s^2) of the
# extruder motor for retractions and extrude-only moves. These
# settings do not have any impact on normal printing moves. If not
# specified then they are calculated to match the limit an XY
# printing move with a cross section of 4.0*nozzle_diameter^2 would
# have.
And if you are using firmware retraction (G10/G11):
[firmware_retraction]
#retract_length: 0
# The length of filament (in mm) to retract when G10 is activated,
# and to unretract when G11 is activated (but see
# unretract_extra_length below). The default is 0 mm.
#retract_speed: 20
# The speed of retraction, in mm/s. The default is 20 mm/s.
#unretract_speed: 10
# The speed of unretraction, in mm/s. The default is 10 mm/s.
You sir should be awarded an gold medal and an high five, i feel so stupid! Ofc i need to define more movement if i klipper should do the movement instead of the slicers “assumptions”…
