Solved 3.5.0rc1: Input shaping causes layer shifts!?
-
Okay, this is weird: I tried to print this attached gcode file for the last days and kept having "bang" noises and layer shifts on the y axis starting at around 5.5...6mm height:
batteriebox_2x_18650_ut_0.15_T1PLA+T2PLA.gcode.zip.gcode (remark: due to the restrictions in the forum, I zipped the gcode file and had to add a ".gcode" again to the name in order to be able to upload it)These bangs happened at places where no obstructions could be seen - in somewhere around the middle of a straight line for example.
Since I am running my printer with StealthChop, I first suspected (despite using 1.8° steppers) something like the thing here in the thread https://forum.duet3d.com/topic/22436/missing-steps-cant-print-spreadcycle-stealthchop-tuning-help/ that @dc42 and @droftarts managed to sort out, herefore I followed what was done there:
- increased current (no change)
- increased the Duet cooling fan speed (cooling fan draws air through ducts that are located in the mounting base of the Duet, see here) and checked stepper driver temperatures (about hand warm / no change)
- increased jerk (no change)
- reduced speed by about 20% (no change)
- used spreadCycle instead of StealthChop (no change as well)
Due to the thread about input shaping causing stutters and blobs here, I disabled input shaping - and bingo, the printer worked as it should.
Since the code above contains an awful lot of accelerations and decelerations in the area where the layer shifts happened due to... well, whatever Prusaslicer did there..., I suspect there might be some uncaught internal communications delay causing this...?

I do not know what the figure means, but I suspect this might be related to the issue I have with the Duet 3 wifi module...?
The question is now: what can I do to get the printer running with input shaping...?

undefined NeoDue marked this topic as a question

@NeoDue if you use mesh bed leveling, set fade height to 3mm and report back whether this alleviates the issue.

@oliof No, I do not use mesh bed leveling.
The j1 has just three measurement points for z - each one above a bed adjustment screw - that are only used with a calibration macro I wrote for the Duet: at the first point the macro redefines the upper limit of the z axis by sending an M208 command, then the printer moves on to the next point and measures every second or so while telling the user to twist the knob left or right (ASCII Art rules
) until the bed is level. That will be repeated on the last point - simple assisted bed leveling which is does its job by far well enough with the (coated) glass plate the J1 has.
Since that recalibration macro has to be started by the user and its only lasting effect is the M208 command saved in a separate file that is called by config.g during boot, I do not expect that to have any influence.But if mesh bed leveling also may cause this, I am am quite tempted to see this as another indicator for some internal communications timing issue - at least I assume mesh bed leveling to be rather calculation intensive as well, just as Input shaping...?
-
@NeoDue No, mesh bed leveling is not calculation intensive, it's just that the short z movements introduce extra segmentation messing with IS in the current implementation

@oliof thanks for the explanation!

Explains the sudden layer shifting I got, going from 3.5.0 b1 to rc1 my prints started
shifting in the Y axis.
Reversing to beta1 solved the problem. -
@oliof interesting. Got the same problem with layershifts
-
This is, interesting. I have NEVER seen a layer shift on my machine. But the first longer one I did after (finally after all these years) enabling imput shaping and .. wham.. woke up to a layer shifted spaghetti monster. (Did happen about Z20, so not a fade issue I'd say.
While it could be a coincidence, this thread caught my eye.

@janjoh @Jimborr @PCR thanks, that is reassuring that I am not the only one with that issue.
I wonder if we could do something to support the devs here to narrow down that issue. Could you each post your config.g that ran when you had that issue and the gcode of the part layer where layer shifting occurred and of some layers below that? I will try to dig through that and see if I see any similarities.
What I expect to find would be an increase of motion steps per length, motor steps or time, since that was a very obvious difference in my case. Layers with a relatively low amount of acelerations and decelerations per length unit printed fine, but as soon as a layer with many of those was printed (in my case probably caused by Prusaslicer varying the extrusion width since I did not really care about the nozzle width when desingning my part), I observed layer shifts when input shaping was active.
I do not know if this might yield a result that actually helps since we would need a dev here telling us what to do, but it is at least a try.

@oliof
Did you mean to add M376 H3 to bed.g (or config.g)?
If so, I did. No change, still layer shifting.config.g

@Jimborr Ah, yes, that seems to be something else that affects Delta printers.

@agmeadows I have a couple of suggestions:
-
Do you have a PanelDue connected? One known cause of network disconnections is running older PanelDueFirmware with recent versions of RRF. Older PanelDueFirmware can't handle the longer object model keys in more recent versions of RRF, causing PanelDueFirmware to recognis that it doesn't have enough buffer space and abandon the JSON parse. Unfortunately it then asks for the data again immediately without leaving a pause. This is fixed in recent beta versions of PaneDueFirmware.
-
The large number of CAN errors probably means that you have a CAN wiring error, or perhaps that you have two boards configured to use the same CAN address. I suggest you try disconnecting some boards from CAN to see which one(s) trigger the errors. Also check that all boards are running the same 3.5.0-rc.2.
-
-
@dc42 I do not have a PanelDue connected. Also, I don't have any second boards connected. I downgraded to 3.5.0-beta.4 which seemed to resolve the layer shifts, but the errors and connection issues persist. If I keep retrying it eventually goes through. The larger the file the more I have to retry.
This is the log after a reset, boot up and then home all:

@agmeadows Just to be clear, can you confirm that you do not have any CAN based boards connected to the main control board? Do you have anything connected to the CAN connector on the board? Perhaps a photo of the board showing your connections would help?
-
@gloomyandy I have no additional boards connected to the 6HC and nothing plugged into the RJ11 connector. Here are two pictures of the board:
I am having strange disconnects as well when uploading files. I spoke with another person on the Railcore Discord server and they are having the same issue. They said, and I quote, "When uploading g code files to my duet3 connection is lost. The larger the file the larger the chance that connection is lost during upload. Using a wired connection directly to the duet."
I am doing the same thing. I had a keystone hack mounted on an external panel. I bypassed that and plugged straight in and it still had the issue.

@agmeadows do you see later shifts?
I see there is this thread:
https://forum.duet3d.com/topic/34247/duet-6hc-randomly-crasing-again/16?_=1705047609298Where you are discussing the crashes you see on the 6HC.

@T3P3Tony Yes. I have since disassembled the printer and reassembled it. The crashing seems to be resolved. Mind you, I could go several months without a problem.
The board just seems to be acting strange. Either the board or the firmware.
