@cadetc RRF 3.4-b2pre isn't compatible with the DSF version from the unstable package feed. We'll update the package feed as soon as the remaining issues with IS/PA are confirmed to be fixed.

I have no problems with the July 28 beta bin
Duet3Firmware_MB6HC-28-07.bin

Print status problem started with the August 1 beta bin
Duet3Firmware_MB6HC-1-08.bin

But as chrishamm said

RRF 3.4-b2pre isn't compatible with the DSF version from the unstable package feed. We'll update the package feed as soon as the remaining issues with IS/PA are confirmed to be fixed.

Problem lays with incompatibilie DSF - only surprised me why works with ver. 28-07 but not with ver. 1-08

dc42

@cadetc thanks.

JenPet

@dc42 I have also tested new version but can't see any improvement

dc42

@jenpet I have just found one cause of the issue with PA. I'll have a new binary soon.

dc42

@JenPet @skrotz @MikeS I have updated the binaries at https://www.dropbox.com/sh/ja08b7qdzsl8kjc/AAAwUbkN2XJvurq5CuQTgx5Wa?dl=0. This version does not give rise to hiccups in my tests.

JenPet

@dc42 PA is still not working for me.

@jenpet please check the firmware date using M115, which should be this afternoon.

To reproduce this, I will need your config.g file and the GCode file you are printing.

JenPet

@dc42 Firmware date is ok

skrotz

@dc42 just starting a print but definite improvement so far. Clunkiness is at least greatly reduced, if not gone. Will see how the print looks in a bit. Sounds much more normal.

dc42

@jenpet I don't see any M572 command in config.g. Are you running without pressure advance?

JenPet

@dc42 M572 is in the start script of gcode

dc42

@jenpet ok, I am running your file now.

Adrian52

@dc42 just completed cal cube with ei3 and 0.8 pa, no clunking, nice finish - 0 hiccups, 0 errors, 0 underruns. Brilliant - thank you.

dc42

@jenpet I am getting the step errors now. Looking into it.

skrotz

@dc42 Happy to report significant improvement with this build printing with PA enabled and ei2 input shaping on. As mentioned clunking is greatly improved, and the print quality is significantly better. No major extrusion issues or jaggedness. There are a few layers, for example on the right side of the X (notably near the middle of it) on the calibration cube that seem slightly misaligned or overextruded, and are noticeably different from a 3.3 print. I do also notice that the X and Y of the calibration cube seem noticeably wider than previous prints. I suspect though that these issues are getting into the nitty gritty of input shaping, and away from the egregious bugs I was seeing, which seem fixed so far with this build.

I will try and do some more test prints today with various things enabled/disabled to gather more data for you. Many thanks for the rapid fixes!

oh and M122 reports no hiccups or errors on this print:

dc42

@skrotz thanks for your feedback.

@skrotz said in RRF 3.4 input shaping preview available:

I do also notice that the X and Y of the calibration cube seem noticeably wider than previous prints.

Is that with input shaping disabled, or enabled? I do expect there to be slight extrusion differences when input shaping is used. I do not expect there to be significant differences from RRF 3.3 when input shaping is set to none in 3.4 and DAA is disabled in 3.3.

There will be a further update when I have fixed the step errors seen by JenPet, which I have reproduced

skrotz

@dc42 The print was with input shaping enabled:

M593 P"ei2" F41 S0.10

I'll try and do some more prints with input shaping and PA disabled in various combinations and see how they compare.

To my eye, the width of the X and Y changing seems likely to be due to input shaping.. not necessarily bugs, but just artifacts of the movement changes happening with ei2 input shaping on. The lines that look slightly misaligned or over extruded after the X feel more like a bug that is still rattling around. More prints with various knobs on and off should help identify that potentially.

dc42

@skrotz I've just found and I believe fixed the bug that was affecting JenPet. It might cause slight extrusion errors on other machines using PA. New binary coming soon.

dc42

@skrotz @jenpet I've put new binaries at https://www.dropbox.com/sh/ja08b7qdzsl8kjc/AAAwUbkN2XJvurq5CuQTgx5Wa?dl=0.
