RRF 3.4 input shaping preview available
-
@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:

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

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

@jenpet
So i tried the latest beta and also noticed cluncky movements. That appeared only when i turned up acceleration to 7000mm/s. It does it also when i do movement for accelerometer to gather data. If i put acceleration down to 4000mm/s it does move smoothly. Also only ZVDD and EI2 seems to be affected. I attach a video of the testing i did. Also wiring is temporary and only for these tests, i'm not measuring real resonance with it i think.@dc42 LIS3DSH working good! Nice work!
EDIT: Just found i was setting an acceleration greather than the one defined in M201.Rising the M201 values solved it.However i think this is not an expected behaviour.
-
@mikes I tried 7000 to 2000 acceleration but the issue is still there. I have tried zvdd and ei2.
I had a similar issue like in your video. Which jerk values do you use?
-
@jenpet Right now these are my settings, but not sure if they are good. I'm just trying atm:
M566 X1500 Y1500 Z60 E8000 ; Set maximum instantaneous speed changes (mm/min) M203 X20000 Y20000 Z6000 E15000 ; Set maximum speeds (mm/min) M201 X20000 Y20000 Z3000 E1800 ; Set maximum accelerations (mm/s^2) M204 P7000 T7000 ; Set printing acceleration and travel accelerations
Be sure that your M201 has higher values that the one in M204. This was the issue for me
-
@mikes I am using lower values, I would try it
M566 X300.00 Y300.00 Z24.00 E300.00 P1 ; set maximum instantaneous speed changes (mm/min) -
@dc42 I think the breakdown so far for 7-28 3.4 build is:
With No PA and no input shaping, things look normal. No extrusion blobs or zits. Corners bulge a bit due to no PA as one would expect. (Just did this print). Things look identical to RRF 3.3.
With no PA, but EI3 input shaping enabled, I get no clunking or hiccups/errors, but I do get some small occasional extrusion zits/blobs, in the same place each print. Corners bulge a bit more than the print with no PA and no input shaping - probably an artifact from the ei3 input shaping?
With PA at 0.12 and no input shaping, I am getting the clunking noise, usually when printing the gyroid infill. I do not get this clunking with 3.3, it is abnormal. The print has extrusion issues.. lines where the head is moving to print the X or the Y of the cube seem to be over extruded at times, some maybe under extruded. Parts of the X look a bit jagged. (just did this print). M122 reports 2679 hiccups but no errors for MainDDARing move stats.
I assume with PA and EI3 input shaping, I'll get clunking plus the layer shift others are reporting, but I haven't done that print yet on 7-28 3.4.
