@adrian52 interesting that you got a layer shift also.. I assumed it was related to me disabling PA because it happened at roughly the same point as when I turned off PA to mercifully end the clunking, but sounds like maybe it would have happened no matter what... probably an input shaping bug then.

dc42

@skrotz @Adrian52 @CadetC @sebkritikel I found and fixed the cause of the stepper errors and associated layer shift, and I updated the binaries at https://www.dropbox.com/sh/ja08b7qdzsl8kjc/AAAwUbkN2XJvurq5CuQTgx5Wa?dl=0. I don't yet know whether this also caused the extruder clunking or that is a different issue.

@dc42 with pa at my usual 0.8, and shaping set to ei3, the new binary still gives pauses and clunking. Towards the top of my cal cube I got a big progressive layer shift in the y direction. M122 gave 5908 hiccups in 17015moves, but no step errors or underruns.
I then set pa to 0 at the console, and without changing anything else, the cube printed smoothly with a nice result; 0 hiccups, 0 step errors, 0 underruns in 18073 moves.

@dc42
Thanks for a update, I'll do test print with change every 25 layers(5mm) as follow "no IS", daa, ei2, ei3, zvdd, zvd -PA set to 0.022 and acceleration 4000, print speed 100m/s

CadetC

@dc42
Print finished/stopped - again best results with ei3 - on pictures from bottom -"no IS", daa, ei2, ei3, zvdd, zvd(failed print stopped)
Everything was fine until the zvd was turned on - . below is a picture of the printout and a link to a video showing clunking noise - you would think that the head is blocking on the rails - which of course is not true

With PA disabled all is OK

@cadetc ei3 has so far seemed to be the best for me as well on my core XY printer in initial testing.

@cadetc please post the GCode file and your config.g.g file,then I will try to reproduce it.

@dc42 since it seems like PA is still having issues, I printed a calibration cube with ei3 input shaping on but PA disabled, and things were fine except for it still having the same extrusion bubbles/zits that aren't present in RRF 3.3 with DAA on and PA disabled (or enabled). No stepper errors or hiccups or clunking while printing with PA off:

=== Move ===
DMs created 83, segments created 35, maxWait 23082ms, bed compensation in use: mesh, comp offset 0.000

@skrotz does PA still have problems if you turn input shaping off?

@skrotz said in RRF 3.4 input shaping preview available:

extrusion bubbles/zits that aren't present in RRF 3.3 with DAA on and PA disabled (or enabled).

I realize this may be a bit of a stretch - are you sure the bubbles/zits problem is not caused by the wet filament? - have you tried going back to RRF 3.3 to check using the same filament that this problem does not exist?

MikeS

@dc42 Is the LIS3DSH already implemented in these beta binaries? If so i could give it a try and check if PA and IS are giving problem also on my build running fine with the stable 3.3. I've already printed some part that i can compare

Yes, but only when connected directly to the main board via SPI at present.

Adrian52

@dc42 it does for me. Cal cube gave similar clunking and pausing, and 6306 hiccups in18073 moves. No step errors, and underruns [0,0,3]. Y shift less, but poor finish.

Adrian52

@skrotz I got a nice result with pa disabled using ei3.

skrotz

@cadetc cubes printed on RRF 3.3 with same filament are fine, and the extrusion issues on 3.4 are not random, they happen at the same exact place each print. It’s not the filament.

Is this with input shaping disabled and PA enabled; or some other combination?

if I understand correctly i can use it connected to the duex5 with a duet2wifi right?

I have tried the new uploaded firmware but I have still the issue, that at the end of an move is not enough material when PA is on.
