@dc42, DSF has also been updated to 3.4.

There is a further update needed to go with this RRF build, not released yet.

@dc42 The extrusion issue with PA is still there. A single wall line starts at my testprint at 0.45 and the line ends at 0.30 thickness.

Is that with or without input shaping applied?

@dc42 With Input Shaping mode zvdd @ 55Hz

@jenpet @skrotz I've just found and fixed a bug that was sometimes causing incorrect axis deceleration profiles when input shaping was used, typically leading to clonking sounds from the motors. On my test system it occurred when using ZVD input shaping but not when using EI3. This would also have affected the rate of extrusion vs. axis movement, which might make it look as though PA was not working properly at the end of a segment.

I have updated the binaries at https://www.dropbox.com/sh/ja08b7qdzsl8kjc/AAAwUbkN2XJvurq5CuQTgx5Wa?dl=0.

JenPet

@dc42 I have tested the updated firmware but see no improvement in my problem with extrusion

dc42

@jenpet thanks for the feedback. I will continue to work on this tomorrow.

@dc42 with this latest firmware I also did not see much difference. with PA enabled I still had extruder clunking and issues with over/under extrusion and jaggedness on some layers, especially where the head was moving to print the X and Y of the calibration cube. M122 reports no step errors but lots of hiccups:

@skrotz I noticed that on my system the axis motors were sometimes clunky, and that led me to another deceleration bug. This may have been the cause of the hiccups that you observed. I have now fixed that and updated the binaries at https://www.dropbox.com/sh/ja08b7qdzsl8kjc/AAAwUbkN2XJvurq5CuQTgx5Wa?dl=0.

@skrotz and @JenPet, if you still have extrusion issues with this build, please test with PA enabled both with and without input shaping enabled, to see if there is a problem with PA even without input shaping.

@dc42 I’m having some issues to collect the data with the version from July 31 using a Duet 3 6HC and Tool board V1.1

M955 P121.0 I25

Fred-Y

I just noticed 2 things:

a file is created to collect the data but it is empty and also seems to stay open

I have to reboot the board and after I can delete it
The temperature only start to act weirdly after I tried to collect the data from the accelerometer.

The arrow is when I ran the macro to collect data, it sounds directly related.

I hope these info are useful, let me know if you would like additional details.

Edit:
I did a little more testing and rolled back the firmwares to get back to a stable version, it seems the issue is with the Tool Board 1LC firmware, it seems to be working fine with this combo:

@dc42 Sorry to always be the bearer of bad news but no real difference with this firmware from what I can tell, still hearing clunking noises and still extrusion issues and jagginess on the print with PA enabled and EI3 input shaping enabled. I will try and do a test with input shaping disabled soon.

UPDATE: started a print with input shaping disabled, and was getting the clunking, maybe even worse than with input shaping on. Disabled PA and things quieted back to normal. I then turned on input shaping back on (with PA disabled) and it still sounds normal, no clunking. so PA in general seems to be the cause of the clunking. I'll see if I'm still having extrusion blobs/zits with PA disabled but input shaping on.

UPDATE 2: still seeing the same extrusion blobs with PA off and input shaping (ei3) enabled.

stats below are from the print with both PA and input shaping enabled:

@dc42 I also tested the new version and couldn't see any improvement.
The issue only happens when PA is on. As soon as PA is off, the extrusion is correct.
It's a problem with PA even without input shaping.

dc42

@jenpet and @skrotz, thanks for your feedback. I am running a test print on a bench setup and getting a slight clunking of the extruder on some moves only when I increase PA to 0.3 or higher. I am trying to track down the cause.

CadetC

@dc42 said in RRF 3.4 input shaping preview available:

I have now fixed that and updated the binaries at https://www.dropbox.com/sh/ja08b7qdzsl8kjc/AAAwUbkN2XJvurq5CuQTgx5Wa?dl=0.

In my case, after installing the latest 3.4.0beta2-inputshaping (2021-08-01) - after starting the print DWC immediately reports the completed print - although the table is just warming up and printing has not even started yet. I cannot stop printing because only the - "print again" button is active - I have to click on emergency stop.
Below is the status screen -after printing has started

Adrian52

@dc42 my experience is similar - I use pa of 0.8, and this gives clunking and poor finish, with and without input shaping, and around 6000 hiccups per 18000 moves for both. Reducing pa to 0.2, still without shaping, gave a much better result, but still 446 hiccups. Clunking still noticeable, particularly on the first half layer of solid infill - the second half of the layer where the line length is decreasing is much smoother

MikeS

@adrian52 I'm printing 2 cubes, one with stable and one with the beta. I'm mid second print and seems that same PA value (0.04) gives different results with the beta... i'll try to post detailed photos of the outcome once it's finished.

I hear less noise from the extruder than latest beta, still there is some there. More noticeable at higher printing speed.

3.3 Stable:

3.4 Beta:

Unluckily i have to dry the filament buut it's the only glossy filament that i have atm and is easier to shot to seeartifacts. As you can see there is something wrong on the edges of beta print. Seems that more PA is needed than 3.3.

Printed with the same g-code with the same settings.

@dc42 seems like same results on this firmware for me. Clunking sounds, and extrusion issues/jagginess on a calibration cube print with PA and input shaping (ei2). my PA is at 0.12.

sorry in previous posts I've been putting my input shaping as ei3, I meant ei2. It's been ei2 not ei3.

Same problem as with previous binaries - after starting a print, the status immediately shows that the print is 100% complete - when I click emergency stop, DWC hangs up and I have to physically cut power to reset the printer
