RRF 3.4 input shaping preview available

Nuramori

Just ran it on a coreXY - that was..... not successful. Everything seemed to work fine (homed correctly, bed leveled), but as soon as it went to print, it sounded like my steppers exploded. lol. Home to 0,0 seemed reversed, and just had to hit the e-stop for the first time in a long time.

Not sure I want to try that again to even get a short video.

Exciting!

Any more insight on viability or timeline for a Maestro build?

Were you running RRF 3.3 stable already?

skrotz

@dc42 Can confirm some weirdness. Was running RRF 3.3 release, uploaded new 3.4 combined firmware to duet2 wifi on a Railcore 300ZL. It reset itself after upload and homing and movement seemed ok, but when actually trying to print it seemed to stall or something, with occasional random movements.

I powered off and on and disabled all input shaping (it still had DAA enabled from my default setup, at 40hz). Was able to print a calibration cube after that, don't know if it was disabling the input shaping that did it or the power cycle. However, when printing the gyroid infill it would make a weird clunking noise that I couldn't identify where/what was happening exactly. Cube printed roughly ok however, but somewhat under extruded so maybe it was extruder motor making the clunking.

Just to be sure, I went back to R3.3 stock and things seem to be printing ok again, no clunk noises, on same exact gcode, so definitely looks like it was 3.4 causing some strangeness.

update: R3.3 calibration cube printed normally, and didn't have any underextrusion issues (or at least, something that looked like underextrusion).

Nuramori

@dc42 Yes, which works very well.

sebkritikel

@dc42 When sending commands via the console on Safari (iPhone), the print freezes, and the console returns the following:

M593 P"zvd" F30
Error: M593: expected string expression

Sending the same command from my PC (Firefox) results in the command being applied, and the print immediately resuming.

Steps I took prior to upgrading from 3.3 stable

Disabled mesh compensation
Disabled pressure advance
Disabled any M593 settings

I had no issues uploading the 3.4 .bin, homing, or starting the baseline print.

A few (ugly) pictures of the results - images showing the ringing are all from the same side, just focusing the camera on the spots indicated in blue boxes. ZVD worked great, ZVDD, EI2, EI3 drifted along the positive X and negative Y directions. IDEX printer, printed with only T0. No pressure advance.

Those of you having issues with these binaries (e.g. clunking or layer shifts), please attach a laptop via USB, load a terminal emulator, and send M111 P4 S1 to enable debug output from the Move module. If during a print it starts outputting DDA and DM listings in that terminal, then please share a sample of that output, your config.g file, and the print file.

If you can't easy attach a laptop, I am still interested in having your print file and config.g if a subsequent M122 report shows step errors is the MainDDARing section.

dc42

@sebkritikel your M122 file shows some step errors. Please share the print file and config.g.

I suspect that your iPhone was sending the wrong type of double quote characters.

dc42

I've just found that one of my other prints is also giving step errors. I'll try to squeeze a fix in this weekend. Until I have a fix, I suggest other users hold off from from using this firmware.

dc42

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.
