Hi,

I printed about 30h or so with RRF 3.6.0-beta2+4 without issues but just now I got this error:

Error: Movement halted because a step timing error occured on drive 2 (code 7). Please reset the controller.

Drive 2 is my left rear Z motor.

@leone

You can find the latest (sub)version of beta 3.6.0 here for now:
https://forum.duet3d.com/post/347763

@Phaedrux

Yes but I can't say whether it has improved compare to RRF 3.4 as I can't remember the results anymore as it's almost two years ago.
With RRF 3.6 beta pressure advance is visually unaffected by input shaping. Corners are very sharp with normal PA values.

@dc42

Thanks! I can confirm that problem has been fixed.

@gloomyandy

With "M564 H0" in config.g you can.

@gloomyandy

Detailed steps:
-> I power on the printer
-> (axis are not homed). I try to move the tool head +10 on x but it goes right diagonal. When I move +10 on Y it somewhat fixes the issue and X moves as it should
-> when trying to home the axis the problem is back again

I recorded a video, maybe then it's easier to understand:

Hi,

because I also got this error with with 3.6.0-beta2+1 :
https://forum.duet3d.com/topic/36988/rrf-3-6-0-beta-2-error-code-7
...I tried 3.6.0-beta2+3 from here: https://www.dropbox.com/scl/fo/pasag1g18orahwvn49qp2/ABWgw6D-TyKWxxurTmGwiUE?rlkey=r9h3rjyw1l4wh7xbr8yho37gw&e=1&dl=0

Problem with RRF 3.6.0-beta2+3:
When commanding +10 on X the tool head moves diagonal. Then I command Y to move back and forth and then back on X fixes the issue and the tool head moves as intended. When commanding to home the axis the tool head moves diagonal again. This did not happen with 3.6.0-beta2+1 (flashed back to confirm).

Just wanted to report that with RRF 3.6 (beta) the issue is gone. Pressure Advance works as intended with input shaping.

@dc42

I can confirm the issues are gone with Duet 3 Mini 5 + Toolboard 1LC

@Exerqtor

It seems it only temporarily fixed the issue. I just startet my printer for the first time since I was able to successfully print a Voron test cube and when inserting filament via PanelDue the extruder runs backwards at 5mm/s and forward at 10 mm/s when commanding it to extrude. With other words the bug came back

@ctilley79

Yes, I also had this issue and the extruder was overall extruding a bit too much filament whilst printing. My normally calibrated extrusion multiplier set in the slicer would not work anymore.

What helped:

• Duet 3 Mini5+ reset + Toolboard 1.2 reset (via button)
• formatted the SD card and copied just the config files
• flashed the Duet 3 Mini 5+ directly over the boot loader as a mounted drive to a PC and then flashed the Toolboard over the web interface

Now the reverse running extruder issue is gone and also my set extrusion multiplier works again.

I don't know what caused the issue tbh. Maybe the countless flashings over the web interface with all the beta versions (I also flashed Klipper to it fort testing purpose) causes issues over time but that's just a wild guess on my side.

@CCS86

Thanks but Flow is tuned right but it won’t work this this beta release. Flashing to previous build or Klipper and the problem is gone.

@CCS86

Worked flawlessly for the past 6 years on several printers.

Pressure advance / corners have been vastly improved! Corners are crisp and infill lines are strong even with input shaping enabled.

Edit:

I take my below reporting back. The printer was behaving very odd today. The extruder changed it's direction and changed it back after pausing. I decided to format the SD card + Reset the board with the button + Flashed the firmware via the boot loader / mounted the board directly to the PC.
Now the printer is behaving as expected and the extrusion issue is also gone. I don't know what went wrong there. Maybe the countless flashes with RRF and Klipper I did in the past did leave some left overs.
I had something similar back in the Duet 2 days after several beta flashes where I also had a bug which I could not reproduce after resetting the board.

But another thing is new and I've just checked my e-steps to rule that out: My slicer extrusion multiplier decreased from 0.91 to 0.89 for PLA.
Is anyone else noticing that? As long as PA is working fine I can live with that but it's odd that after the update I had to re-calibrate my EM.

Edit:
I've had to decrease EM to 0.868 in order to have a mechanical fit of two parts without much friction.
But you can see that the layers have gaps which indicates under extrusion. My old calibrated EM was 0.91.
Something seems off I guess?

@ctilley79

I'd say it's a 80% improvement to before and compared to my printers with Klipper or Bambu X1.
So it was definitely a step in the right direction.

@Monteaup

It seems some extruder / hotends cause issues with the PA implemenation we have atm with RRF.
With Klipper you also would need to play around with "PA smooth time" so PA does work properly. Maybe we'll see such implementation in RRF anytime soon.

I already tested different slicers and settings also different RRF versions.

Only thing that helped with my machine was connecting Klipper (Pi).
I suspect that PA smooth time is the factor (feature) that is RRF missing to improve this.

But the reasons why my bedslinger (also RRF with Duet 3 Mini) produces better corners? I don't know. My Voron (printer with the issues) uses a different kind of hotend which is also not compatible with the PID algorithm RRF uses as PID tuning only works when calibrating the hotend as heater and not as a tool But that's another issue I already reported in another thread.

@Heartleander81

I see.

I know from another Klipper user that he also only could get nice corners by playing around with the smooth time setting. Pressure advance alone did not help much.

Maybe extruders / hotends are so particular nowadays that we need this setting to get nice corners?

Here is the example from the user I'm talking about:

He has a bowden setup and needed to increase the smooth time in order to get nice corners. PA alone did not the trick.

@dc42
How high are the chances we might get this feature for RRF? I think this might very much help those who are having problems with PA at the moment.

@Heartleander81

So altering the smooth time value did improve your corners and PA alone did not?

@jay_s_uk

Did you already have the time to print a comparison between RRF and Klipper on your setup?
