Unsolved G2/G3 arc slow down
-
Hi,
I am performing various tests and configurations on a clay printer. I have noticed that when I generate the gcode with the instructions G2/G3 it reduces the speed to half when I make the movement of an arc.
Do you know what could be the cause of this. I have checked the Gcode and I don't see any Fxxxx command before the arcs.
Do you know if it could be a config.g parameter or is it something in the firmware?Thank you.

@amimafe You may want to check your Jerk settings, the Arcs will internally be turned into a series of short lines and the jerk setting will limit how fast the printer can handle the transition from one line to the next.

Hi @gloomyandy ,
The problem I see is that if I increase the jerk to improve the speed of the arcs, when the printer makes a corner it will make a very strong jerk.
Is there no way to make the printer perform a constant movement as if it were performing a straight line? -
@amimafe I don't think there is, you basically have jerk, acceleration and speed to play around with. You may want to take a look at some of the discussions in this thread: https://forum.duet3d.com/topic/36505/fw-3-5-2-high-jerk-good-for-circular-path-not-for-corners

Wow, it's certainly very interesting and I think it might be just what I needed. I will study it well and give an answer.
Thank you very much
