However when viewing the preview with the movement speed as the color display it does show the dense layers moving at the default
print speed. I guess it must be my speed estimation settings that are not working correctly I will do a few large test prints to get the real time
Thanks for providing the .factory file. I've had a look at it and made some "tweaks"... I just put a model on the print bed and scaled it up
200% for my experiments.
Using the slicer settings as provided in the .factory file, print time for my model was: 4hrs, 45mins
after making some adjustments, I'd managed to reduce the print time to 3hrs, 27mins
. The TL;DR out of
all of this is that your infill & retraction settings play a HUGE role with respect to print times.
Here's a list of the changes that I'd made along the way...
Speed Overrides Section:
- Changed inner perimeter speed to 85%
- Changed XY travel speed from 80mm/sec to 100mm/sec
- Unchecked "Reduce print speed for excessively quick layers" <-- this factor affects print times when enabled for small models
- Unchecked "Reduce print speeds for short perimeters" <-- this factor also affects print time when enabled for small models
- Changed "Dense infill percentage" from 99% to 80% (99% seemed excessive, top layer will still be smooth @ 80% dense infill)
- Changed infill from 15% to 5% <-- This is where the bulk of the print time savings come from!!!
- Unchecked "Perform Tool Change Retractions"
- Unchecked "Only retract when crossing open spaces"
- Unchecked "Force retraction between layers"
- Checked "Require minimum extrusion for retraction", set value to 3.00mm
Hopefully this might give you some insight for getting the print times down for your model(s).
You don't know what you don't know until you know (my philosophy for continued learning).
