Weird #3dPrinting question I've been thinking about.
Would the left side print faster? (Assume that both discs in the photo below are the same diameter and height.)
My assumption is that it would. The print head could accelerate during the chunky segments but the right side would be constantly changing directions, so no acceleration.
If it would be measurably faster, I'm not sure. I need to do some testing, but it's interesting to go against years of optimization in the other direction.
@linux_mclinuxface I doubt it. The larger the facets the larger the included angle and the more it needs to slow down between facets.
It's not just segment length, it's the angle between the segments.
The details depend on what firmware you are running. In Marlin, this is directly set as "junction deviation" and in klipper it's set with square_corner_velocity
. from which the junction deviation is derived.
Don't fight your years of optimization making better parts.
@linux_mclinuxface Here is the Klipper issue [github.com] that covers Grbl and Smoothieware and why the setting is different in Klipper.
Marlin's junction deviation documentation [marlinfw.org] is lighter in detail. I do remember configuring that by trial and error until prints looked OK to me back before I moved to Klipper.
