RRF 3.4 input shaping preview available

[MikeS]

@dc42 thanks for the new release. It seems that is running good, you should call the next beta "clunk free".

However i noticed i can't stop during mid-print because the firmware goes to status "generic.status.cancelling" when cancel button is pressed. From there i can't press the cancel anymore and the printer won't start a new job

@mikes, that bug was fixed in the 3.4.0 beta 2 release.

[MikeS]

@dc42 i lost one day and the beta is already out! thank you!

[dc42]

I wish to thank all who have tested the RRF input shaping previews. With your help, I believe I have the new step generation code working well including input shaping and pressure advance. This has given me the confidence to include the new code in RRF 3.4.0 beta 2 which we released today.

Please upgrade to that release, and start new threads for any issues you encounter with it.

@jenpet said in RRF 3.4 input shaping preview available:

@dc42 the two contour lines get thinner and thinner at the end so that there is a gap between them.
Now I try to lower PA value again.

If you mean the two perimeter lines, they are joined in the perimeter at the top, joined for part of the length of the perimeter on the right, and not joined at all in the perimeter at the bottom. The difference between top and bottom suggests to me that you have chosen an unfortunate wall thickness and the slicer has failed to ensure consistent infill by altering the extrusion widths - so that whether the perimeters are joined or not is very sensitive to small changes. I am assuming that the thickness of all three walls is supposed to be the same.

I also have problems with pressure advance and input shaping with de PA values I already got finetuned without input shaping.

Top one: input shapping ei3 @48Hz + PA 0.1 (orbiter extruder direct)

Bottom one: just input shapping and no PA

Both 100mm/sec, 6000mm/s2 acceleration

You can see corners are ok with the PA, and bulges with no PA...
