3.4.0 b3 leaning prints
-
When I’m back home I’ll also post the gcode and configs.
But like Id like to emphasize again that the same gcode produces flawless prints on 3.3 and crooked ones on 3.4b3. And they were all „ hollow cubes“
I’ve even used Cura Arachne and Prusa slicer and I had the same issue with both.Anycubic Predator, Orbiter Extruder , Duet Wifi, Mosquito Hotend, Remote Extruder Stepper cooling and Part cooling

@t3p3tony I think it might be related to y direction travel between objects. With two simple 20x20x20 cubes displaced 40mm in the y direction but aligned in the x direction, I get a pronounced (18deg) slope in the - y direction on both cubes . Printing the same two cubes aligned in y but displaced in x seems to give straight sides.
-
@cabalsoul yes I understand that. I don't think its the gcode itself that is the issue (or even your config). Just need to be able to replicate the issue in order to help @dc42 work out what's causing it!

@adrian52 the theory I am working on would make it sensitive to the start and end points of the move, the acceleration, the requested top speed, and the input shaping. A cube with infill has a variety of moves with different start and end points, so would make leaning more likely. A hollow cube does the same XY moves over and over again, so you would be less likely to hit a problematic move, but you might hit one if you shift the cube.
Unfortunately, the rod length, delta radius and steps/mm are also likely to affect whether a move is problematic or not.
If you have a simple print that reproduces the problem readily, it would be helpful to me if you can test which of the following changes makes the problem occur or go away:
- Changing acceleration
- Changing requested speed
- If you are using input shaping, turn it off or change the frequency.

@adrian52 ok thanks. I will try and do the same. are your test cubes hollow or with infil? are you using input shaping?
-
@t3p3tony I used 10% gyroid infill, and ei3 input shaping
-
@dc42 I have some more to add to the theory
Both cubes are printed with 3.4b3.
The right hollow cube is printed in vase mode.
The left hollow cube was printed as a single wall. This one had a z hop setting of 1mm
I am currently printing the same gcode with no z hop and it is not exhibiting the same leaning in Y.

@jay_s_uk that's interesting! Is the Z hop configured using M207 and firmware retraction, or in the slicer?

@dc42 using M207.
The gcode files are the same.
I changed it to 0 using M207 from the console and checked it to ensure it had changed -
@jay_s_uk thanks. Please share the GCode, and I will try it on my delta with Z hop this afternoon.

@t3p3tony have now tried the two cubes without infill, without input shaping, with z hop=0, and with pa=0, and the slope in the - y direction is the same.
-
@adrian52 so its not z hop.
that just adds to the complexity then -
Here is my config and the example gcode. All my prints were printed in vase mode, no Z hop configured for PETG.

@cabalsoul thanks. so I have managed to get a lean on "simpler" boxes printed as @Adrian52 suggested, offset in the +/- Y direction. (using gyroid infil and el3 input shaping)
Has anyone observed sloping in any direction other than -Y ?
-
@t3p3tony In my case always -Y.
If i rotate the object it doesn't change anything. -
@t3p3tony in my case it is also always in -y and happens regardless of position on the build plate
-
@t3p3tony It seems that I got one of my prints leaning on both -X and +Y
On this picture it is leaning on the left and also back.
I spent quite some time today trying to reproduce the issue on simple objects like basic cubes, calibration cubes, ringing test with and without infill (rectilinear, gyroid...) but all seems fine.
I guess I changed something on SuperSclicer
... I even checked I was still on the beta3. -
@fred-y thanks for spending the time in testing this - it helps!
I will test to see if I can get a lean with the two box prints arranged in different orientations then looking for anything on +/-X
-
With a 20mm cube and a 20x20x10high cube offset in the y direction printed together, the 20mm cube (on the right) looks like this
The left cube for comparison printed with no y offset. You can see that the lean reduces after 10mm, but interestingly a smaller lean is still seen. Havent tried a 45deg rotated cube yet.
