RRF 3.4 input shaping preview available

dc42

@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.

Argo

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)?

dc42

@argo the automatic shaper recommendation generator is under development.

skrotz

@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.

dc42

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

@skrotz said in RRF 3.4 input shaping preview available:

@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.

Interesting, my Duet WiFi powered delta normally runs at PA 0.2 and has been fine. My tool changer didn't have the correct extrusion with the earlier firmware, but that uses a tool board and it is running fine now with the later firmware.

skrotz

@dc42 definitely some extruder weirdness for me that I don't get on 3.3.

I only had PA on briefly (the clunking is disconcerting) on a test print of a calibration cube but did notice this from M122:

my extruder motor is the standard LDO one in a filastruder railcore kit, used as a direct drive.

dc42

@skrotz thanks.The step errors are not right. Please can you connect a laptop to the Duet via USB, load a terminal emulator (e.g. YAT), and send M111 S1 P4. That will enable Move debugging. Then run that print. For each step error recorded you should get a few lines of DDA and DM printout in the terminal. Post those lines here.

Also please post the print file and your config.g.

Argo

@dc42

Using the same frequency with ZVDD or other shaper is giving me worse results. I don‘t think I can just use the measured ringing frequency with shapers other than ZVD?

skrotz

@dc42 it took a bit of finagling to get things hooked up to the PC, but so far even though I heard the clunking it didn't output anything on the terminal at that point even with the debug enabled. I may be able to try again later, is there anything else I could/should enable? an M122 after stopping showed "hiccups" but no stepper errors at that point. I only did a small amount of the print though, I had to stop as I think I injected something via the terminal at the wrong time and caused some problems.

I've included my config file and the gcode I'm printing.

config.g

CFFFP_xyzCalibration_cube_195.gcode

dc42

@skrotz please can you try again, this time wait until M122 shows some step errors, as it did in your previous M122 that you posted here.

Some extduders do sound clunky when used with pressure advance, however it shouldn't be different in the latest 3.4 with input shaping compared to 3.3.

OwenD

@dc42
Just an update.
Upgraded to the latest binary.
This time the print completed with no apparent missed step issues, or clunking including during sectioins using DAA.
No step errors in the M122 report, but a couple of hiccups.

Too late in the night to evaluate the results in regards to print quality of each mode.

skrotz

@dc42 There's definitely different behavior between 3.3 and 3.4 - no clunks on 3.3. I need to do a quick print on 3.3 with PA disabled to double check some strangeness I see with same on 3.4, then will try and collect the data again, I think I sorted out what went wrong previously with my 3.4 print (user error basically).

skrotz

@dc42 ok I did a simple print of the xyz calibration cube on 3.3 with PA disabled, and it looks clean, but the same print on 3.4 shows some zits or bubbles in spots that don't show in the 3.3 print - it looks like it is overextruding sometimes before it changes direction, they occur in several spots on the "X" of the calibration cube. They are consistent in where they occur in 3.4, multiple prints show them in the same places. Something is definitely wonky with extrusion in general for me in 3.4, and made worse when PA is enabled.
