Hello everyone.

I would like to reduce my acceleration and jerk to a minimum to get the best quality possible, what are your recommended minimum settings?

Can some one also provide me with the gcode lines for the starting script for acceleration and jerk?

thanks so much!

I have found that things are pretty clean with X and Y at 900.
I have settled into using a JERK setting .1x the XY acceleration.

M201 X900 Y900 E5000 ; acceleration
M205 X9 E5000 ; jerk

I usually run at
M201 X1600 Y1600 E5000 ; acceleration
M205 X16 E5000 ; jerk

for faster print times.

thank you!
just what I was looking for!
and what kind of time difference do you note between the 2? is it double the time or just a fraction?

I have recently used the website http://gcode.ws to get better estimates of build times. It takes jerk and acceleration into account where slicer estimates I've seen don't take those settings into consideration.
