RRF 3.4 input shaping preview available

I have now updated the binaries at https://www.dropbox.com/sh/l020weqx7pijv84/AACFM3knhVXQ1hKu6NyKOfx6a?dl=0. These fix the bug that gave step errors when running one of my tests prints, so they may well fix the main issues that other users found when using the binaries that I posted yesterday. I also found and fixed a less serious bug that sometimes caused an incorrect amount of extruder retraction at the end of a move, when medium to large values of pressure advance were used.

[skrotz]

@dc42 Tried the new firmware, did a full power cycle after installing just in case. Had same clunking noise on printing a calibration cube on the infill. I discovered disabling pressure advance caused it to stop clunking.

Normally I have S 0.12 for PA, with a little experimentation anything at 0.4 or above (ish) seems to cause the clunking noise. If there's specific debug that would help with this, I can try and gather it.

[dc42]

@skrotz thanks. I've only tried pressure advance up to 0.2. It sounds like I have a little more work to do to get it right.

After you have run a print with high PA and had the clunking, does M122 report any step errors in the MainDDARing debug?

[dc42]

@skrotz PS - is your extruder drive connected to the main board, or to a CAN-connected expansion or tool board?

[dc42]

Last update for tonight. I've updated the binaries at https://www.dropbox.com/sh/l020weqx7pijv84/AACFM3knhVXQ1hKu6NyKOfx6a?dl=0 once more:

• These binaries are based on RRF 3.4.0beta1. This means that if you want use them with attached SBC, you must first upgrade to 3.4.0beta1 from the unstable feed on the package server; and then upgrade to the input shaping RRF binary. The benefit is that you will be able to collect data from an accelerometer if you have one. If necessary you can downgrade later to the standard RRF 3.4.0beta1 binary from https://github.com/Duet3D/RepRapFirmware/releases/tag/3.4.0beta1.

• I fixed a bug that caused extrusion to be inaccurate when the extruder was driven from a CAN-connected tool or expansion board.

You're too quick on the updates!

Was testing your previous update,'none', 'zvd', 'zvdd', 'EI2', and 'EI3' all work as expected. 'daa' does some wonky movement - unfortunately I mistakenly cleared out the terminal logs, so I'll retest 'daa' on your newest version hopefully sometime soon.

[dc42]

@sebkritikel thanks for testing it. DAA uses a different section of code from the other methods, so it could quite easily have different bugs. I'll quite likely remove support for DAA if the other methods turn out to be better, as I expect.

[OwenD]

@dc42 So far I have found as soon as DAA is enabled I get a massive layer shift and it stops extruding.
Currently testing other modes as I had DAA first.'

Can confirm all other input shaping modes worked but daa causes step loss every time.
Also stops extruding for some reason.

@owend I confirm there is a bug in the implementation of DAA. I hope to get time to fix it today.

[dc42]

I have updated the binaries at https://www.dropbox.com/sh/l020weqx7pijv84/AACFM3knhVXQ1hKu6NyKOfx6a?dl=0 again:

• Fixed a bug that caused incorrect movements when DAA input shaping was selected
• Fixed a bug that sometimes caused incorrect extrusion on CAN-connected extruders when pressure advance was used
• Fixed a bug that caused a filament error pause to lock up if the pause.g file used certain commands in combination, e.g. a M106 command followed by a tool change
• Increased Duet 3 MB6HC Ethernet task stack size by 50 words
• Fixed a bug that caused a crash when the slicer labeled objects using M486 and there were more than 20 (Duet 2) or 40 (Duet 3) objects on the build plate. Unlike the other ones, this bug is also present in RRF 3.3 stable and 3.4.0beta1.

I have tested that movement with DAA enabled is now working; however on my delta printer, when printing the test piece it's much less effective at reducing ringing than the other shaping methods. I have also tested with pressure advance set to 0.5.

@dc42
I got Duet3 + toolboard ver1.1 installed - Today i have upgraded to 3.4.0beta1-inputshaping (2021-07-11) - i have then used latest binaries to be able use accelerometer in SBC configuration. -when i try to G1 X-50 G4 S2 M956 P121.0 S1000 A0 G4 P10 G1 X50 F20000 i received Error: M956: Accelerometer not found but when i send M120 B121 in response i got : Accelerometer detected: yes, status: 00
Is this got any thing to toolboard still being: Duet TOOL1LC firmware version 3.3 (2021-06-15 16:12:58)? is there any files to upgrade TOOL1LC to 3.4 firmware?

[dc42]

@cadetc you don't need to upgrade the tool board firmware. I assume you have verified that you are running DSF 3.4.0b1 on the Pi. We are looking into a possible cause of the problem you are having with M956.

@frederik thanks, we have identified the cause. Fixing it will require a change to DSF on the Pi.

Meanwhile, you should be able to send the command to the Duet from an attached PanelDue if you have one, or via USB.

Measurement without input shaping (Y axis):

With ZVD input shaping:

The print results to also show that it is working.
I also have no issues with PA nor was it necessary to recalibrate PA.

Is it planned to to be able to use different shapers and frequencies per axis or to use an "automatic frequency and shaper finder" in conjunction with the accelerometer (like Klipper does)?

@argo the automatic shaper recommendation generator is under development.

@dc42 I mis-typed, I meant that PA clunked unless I took it down to 0.04 (not 0.4), reducing it from my usual 0.12 value. Sorry about that.

I've grabbed the latest firmware and still have that same result of clunking with PA at or above 0.04 or so. My extruder is attached to E0 on the duet2, I have a pretty standard railcore setup, so I have z steppers on a duex5 but X/Y and E0 are on the duet2 wifi.

Aside from the PA clunking, everything else so far seems fine, things were printing ok with DAA, and now with zvdd in some quick tests.

@argo, as you have a fairly broad resonance, ZVDD will probably work better than ZVD.
