Acceleration

[Rebekah_harper]

Hi team,

I would like to see all the speed settings to have adjustable acceleration feature associated with them.

I found this in Cura and makes for smoother motion, avoiding the jerking movement.

It allows for faster prints as I have found when I try and push my printer it doesn't like the jerks. but with cura I reach higher speeds especially in first layer.

kind regards

Rebekah

I agree. I was surprised to find no acceleration adjustment option. I think of this program as purporting to give full control of the 3d printing process. We don't always need full control until there are problems, but I'm seeing some issues that I can currently only fix by going slower with S3D, whereas I can solve the same problem by adjusting acceleration in other slicers.

I wouldn't mind seeing this feature implemented as well.

In the mean time, if you have't found a solution yet, and depending on your machine, here's a bit of code that will help... These codes may potentially vary for your printer, so before using them verify that these are correct with the manufacturer.

M204 S300 ; M204 = Set Acceleration ; S300 = Acceleration mm/s

M205 T0 X1 Y1 ; Set Jerk ; T0 = Extruder (adjust as needed for multi-extruder mahcines) ; X1/Y1 = Jerk of 1 (lowest value) with a rate of up to 20 (which I believe is the highest value and default)

I've noticed that most default acceleration rates default to 1,000mm/s and with some machines with a direct control pad may have a minimum of 500mm/s. Using the above code will override your printers defaults. Upper limits of acceleration may also vary from 5,000 - 10,000mm/s.

Good luck!

Very sad this Option isn`t implemented in 4.0

It's not something that influences other features of the configuration, does not change throughout part etc.. normally it's part of startup script and since Simplify3D gives ability to customize startup script implementing a feature to "add stuff to startup script" is waste of resources. Better add something more useful. Acceleration would make sense if you could change acceleration to have different values in different segments of the print so if you have a corner that's "sharp" you reduce acceleration and jerk, and then get them up again when you have corners that are not that "important" ... that would maybe be a great feature, to have "variable acceleration and jerk" .. but just "configure acceleration for startup script" - it's something set to "safe value" by the printer configuration

I wish to change the Acceleration and jerk in Lines 1;3;5;7;9...... and with litle other Parameters in Lines 2;4;6;8;10......
to reduce the Shadowing
If Acceleration and Jerk on all Lines the same, vibrations from the Printer amplify on the Surface.
