@NeoDue @oliof please try the new firmware at https://www.dropbox.com/scl/fo/p0136wx04h8xf6ejwdnn9/h?rlkey=efrfwyb6o5tqid11gustz3uvy&dl=0. This fixes the interaction between extruder PA and IS.
If you get any layer shifts or hear any strange noises (e.g. bangs) from the motion motors, please run M122 and post the report here. Note, each time you run M122 it clears the accumulated debug data after reporting it, so only the first M122 report taken after a layer shift or strange noises contains useful data - although of course if you get another layer shift or strange noises after running M122 then you can run M122 again to report data relevant to those events.

@dc42 I will do so next weekend, unfortunately no play time beforehand.

@dc42 Great! I hope I can manage to test tomorrow or wednesday!

@dc42 I'm still getting layer shifts.

@adrian thanks. Your M122 report contains useful data. Please can you share your config.g file and any other macros it calls, daemon.g if you.use it, and the print file. Also the approximate height at which the first layer shift occurs.
-
@NeoDue @oliof @adrian I have identified and corrected another step timing anomaly. Please try the updated files at https://www.dropbox.com/scl/fo/p0136wx04h8xf6ejwdnn9/h?rlkey=efrfwyb6o5tqid11gustz3uvy&dl=0.
As before, if you get any layer shifts or hear any strange noises (e.g. bangs) from the motion motors, please run M122 and post the report here. Note, each time you run M122 it clears the accumulated debug data after reporting it, so only the first M122 report taken after a layer shift or strange noises contains useful data - although of course if you get another layer shift or strange noises after running M122 then you can run M122 again to report data relevant to those events.

@dc42 I am afraid your last changes might have made things worse: one slight "bang" noise already layer 3, and layer shift at height 1.4mm.
The test part is the same as in my previous tests.
Here is the M122 readout of the bang:

I could directly turn blob occurrance (and therefore rumbling on the next layer) and off by switching between IS on and IS off.
Edit: In case it matters: the "test-blob" I found occurs on layer 2, 4 and 6 in the middle of the last line of the solid infill of my test part. Prusaslicer decided in its wisdom to split this line into two long pieces which are connected by two very short ones. This is the gcode that causes the blob:

@NeoDue thanks for testing the latest firmware. TBH I wasn't really expecting this latest change to fix bangs and/or layer shifts, because it shouldn't directly affect axis motors. However, the anomalies reported by the "min interval" report in the Move section have disappeared in your latest M122 reports, also the ebfmin value is now zero as expected instead of -1.
I ran your compete print (without filament) on my bench system, apart from the first few layers which I had previously removed because no anomalies were detected in them. The print completed without incident. I didn't hear any bangs, but I can't say whether there were any layer shifts because the motors were not connected to axes.
I would love to have a print in which bangs always occur at the same places, because that would give me a chance to replicate the issue. However, the impression I have from the reports in this thread is that the bangs and layer shifts are somewhat random, because they don't consistently occur at the same places in the print. Would you agree?
Are you still confident that the bangs and layer shifts don't occur when IS is not enabled?

@dc42 said in 3.5.0rc1: Input shaping causes layer shifts!?:
I would love to have a print in which bangs always occur at the same places, because that would give me a chance to replicate the issue. However, the impression I have from the reports in this thread is that the bangs and layer shifts are somewhat random, because they don't consistently occur at the same places in the print. Would you agree?
Are you still confident that the bangs and layer shifts don't occur when IS is not enabled?Yes, to doublecheck that was the intent behind the test I mentioned in my second post today.
The blob I mentioned there seems to reliably be created with IS on even if it is obviously not large enough to create a layer shift every time. The randomness of the layer shifts (edit: except the one at 5.65mm, which seems to be reliable so far!) might indicate that these are created by such blobs as well - there are numerous occurrances of such short moves in the code file.
Edit: Maybe one more question...: let's assume my thought above is correct. On the other hand, I am confident that you dug out and eliminated all the issues of the code.
Can you think of a setting or a combination of settings that - with the RRF input shaping code working as intended - might be responsible for creating a larger blob with IS enabled for this given gcode snippet than it does with IS off? I am thinking of things like "IS changes Pressure Advance which may have such an effect on very small moves if PA is not 100% correctly calibrated" or such.
In addition, I would assume it should be something that does not happen in the Marlin implementation of IS since I did not have any of such issues prior to switching to the Duet. -
@dc42
My layer shifts are in random places and directions. Mine seem like it decides randomly to turn early. -
-
@adrian Can you place the gcode file on a file sharing service and make it available via that?
Have you confirmed that if you print the same part with input shaping turned off (and no other changes), that you do not see any layer shifts?

@NeoDue I would like to check whether extrusion issues (blobs and similar) are responsible for the layer shifts or not. This is what I propose:
- Adapt the attached macro for your machine and test it. It measures where the homing switches are found and compares this with where they should be. It doesn't seem to work very well when using stall homing, but I am hopeful that it will work fairly well on a machine with real homing switches.
- Edit your print file if necessary to remove any homing command at the end
- Remove the filaments from your machine
- Home the printer and run this macro to check it is working as expected
- Disable your filament monitors (M591 D0 S0 M591 D1 S0)
- Run the print like that, using your usual IS and PA parameters that provoke layer shifts
- When it has finished, make sure that the print head is clear of the print, then run this macro again to check whether either X or Y has shifted.
-
@gloomyandy
I’ll work on getting that code shared out.It works fine without IS on.
-
@adrian please can you do the same test that just asked NeoDue to do, i.e. run the same print without filament and use the macro to see whether either X or Y has shiftted.

@dc42 thanks! I have rewritten the file to save its data in a file:
; Parameters to control motion to sense endstops. Copy these from the homing files. var xHomingSpeed = 500 var yHomingSpeed = 320 ; uncomment and set current if stall homing is used ;var xHomingCurrentPercent = 25 ;var yHomingCurrentPercent = 25 T0 ; activate correct Tool - the one on the X axis G91 ; relative positioning G1 Z5 F360 ; get some distance between nozzle and bed / part G90 ; absolute positioning ; Go to bed centre G1 X{(move.axes[0].max + move.axes[0].min)/2} Y{(move.axes[1].max + move.axes[1].min)/2} F3000 ; Reduce currents in case we are using stall homing - uncomment if stall homing is used ; M913 X{var.xHomingCurrentPercent} Y{var.yHomingCurrentPercent} M400 ; Check Y axis if sensors.endstops[1].highEnd G1 H4 Y{move.axes[1].max+20} F{var.yHomingSpeed} echo >>"axisshiftcheck_results.txt" "Y homing error was "^{move.axes[1].machinePosition - move.axes[1].max}^"" echo "Y homing error was", move.axes[1].machinePosition - move.axes[1].max G1 Y{move.axes[1].max-20} else G1 H4 Y{move.axes[1].min-20} F{var.yHomingSpeed} echo >>"axisshiftcheck_results.txt" "Y homing error was "^{move.axes[1].machinePosition - move.axes[1].min}^"" echo "Y homing error was", move.axes[1].machinePosition - move.axes[1].min G1 Y{move.axes[1].min+20} ; Check X axis if sensors.endstops[0].highEnd G1 H4 X{move.axes[0].max+20} F{var.xHomingSpeed} echo >>"axisshiftcheck_results.txt" "X homing error was "^{move.axes[0].machinePosition - move.axes[0].max}^"" echo "X homing error was", move.axes[0].machinePosition - move.axes[0].max G1 X{move.axes[0].max-20} else G1 H4 X{move.axes[0].min-20} F{var.xHomingSpeed} echo >>"axisshiftcheck_results.txt" "X homing error was "^{move.axes[0].machinePosition - move.axes[0].min}^"" echo "X homing error was", move.axes[0].machinePosition - move.axes[0].min G1 X{move.axes[0].min+20} ; Restore motor current M400 M913 X100 Y100 M400 G91 ; relative positioning G1 Z-5 F360 ; move bed back to where it was G90 ; absolute positioning ... and have added an M98 command into the appropriate places of the print file. I will let that run tonight.
