Solved 3.5.0rc1: Input shaping causes layer shifts!?
-
@droftarts Edit: I just managed to catch a glimpse through an unused former USB port opening. If I saw correctly from the reflection, the four voltage LEDs are active, but that's about it. But as noted above, I need to take open the compartment to get a clear look.

@vaike_peeter thanks for the data. How confident are you that if you disable input shaping, you can do the same print at the same speed without getting any layer shifting?
-
@dc42 I will do teat print with IS disabled and then post results. I modified my config for x and y steppers and changed print external perimeter accel to 2000 because of ringing. Defaul accel is 5k. I’m off my printer right now.

@dc42 Okay, after a flash with Bossa the printer is up and running again ( @droftarts it turned out to be an outdated IAP file after all, the last version is from November '22 and mine was from June '22), and here is the requested data:
The print file is in the first post of this thread.
The current config.g is this one, it includes the M593 command:

The layer shift (in y axis direction) occurred at 5.5 or 5.65mm height. It might be worth to point out though that while I got a layer shift of several millimeters with rc1, now it is only some tenths of a millimeter.
Luckily, I sat directly at the printer and watched it while that happened. One thing is worth noting:
I got an audible low-frequency-"bang" from the printer twice around this height and the whole table (which is a solid 40kg wood plate mounted on electric frame) was shaking - something it only does if the y axis does some really hefty acceleration or deceleration. One of these "bangs" created the small layer shift. The printer was printing one of the inner perimeters of the outside surface of the print and did not cross any perimeters or holes in the structure at the time.
Please note no protruding material or such was there that might have blocked the nozzle, and the noise was also quite different from when that happens - such a print error usually creates more of a"rumbling" noise on my printer, with a higher-pitched "klack" or rattling noise if the motor looses one or more steps that it wants to make.
If I would have to conclude what might have created that noise, I would say the Y axis got... well... delayed and had to hurry to catch up, if that does make any sense... -
@NeoDue you need to switch to spreadcycle to avoid the bangs which happens when stealth chop switches modes, change M569 to use D2 rather than D3.
-
@oliof Thanks, but a bang that happens only with Input shaping active has nothing to do with StealthChop unless I overlook something serious. Apart from that, I already had this problem and had solved it - take a look at the additional V parameter in my config.g, that switch you mention never happens
I rather fathom if dc42 can find why I have such an amount of CAN errors (without actually using CAN for anything, probably apart from internal Duet communication...?) the problem might vanish.
-
@NeoDue if the switch never happens you reduce the attainable torque of your motors. You really want spreadcycle for faster motion.
-
@NeoDue said in 3.5.0rc1: Input shaping causes layer shifts!?:
@oliof Thanks, but a bang that happens only with Input shaping active has nothing to do with StealthChop unless I overlook something serious. Apart from that, I already had this problem and had solved it - take a look at the additional V parameter in my config.g, that switch you mention never happens
I think it would be worth running a test to be sure. Do you still get the layer shift if you run the same print with the motors in Spreadcycle? If not that might help us determine what is causing the layer shift. It may be that something in the way the IS pulses are generated is triggering a mode switch.
-
@oliof Well, I simply copied the behaviour of the original Snapmaker Marlin board there which probably means they chose the motors accordingly, and I do not have any issues obviously resulting from lacking motor torque. On the contrary - the printer is very well capable of getting the nozzle over significant buildups in the currnet configuration which makes me more fear for the linear bearings
Therefore I do not see any need for Spreadcycle. The only thing that does is making the printer noisy, at least for the speeds I am running at.
But you are right: the basic noise did sound like the "StealthChop -->SpreadCycle-Bang".@gloomyandy I will test that. One more thing: I did a second print over night, and is seems the layer shift does not occur as reliable as it did with rc1. Therefore I will rather focus on whether the "bang" will occur or not since that seems to be an indication of the primary fault which then may cause the shift, okay?
-
@gloomyandy I just ran the test with every "M69...D3..." in the above config replaced with an "M569... D2...", and I got a layer shift of about 1,5mm in x direction at 2.8mm height. Here is the M122 message:

I will let the print run on until it reaches the height where got issues before and add the result to this post.
Edit:
a second layer shift occurred as expected - same height and same direction (y) as in the test above, again with a "bang" (which did however sound more silent as when I use StealthChop.

(edit: corrected height of 1st layer shift)
(2nd edit: I just saw that I did two additional smaller layer shifts in Y between the two that are mentioned in this post, so there are four in total) -
@NeoDue Thanks for running that test, I notice that you have a number of custom driver settings using M569 and M915, how did you choose those values?
-
@gloomyandy yes, you are right - my X and Y steppers are set with an M569 P0.0 S0 F4 Y1:2 D2 H5 V25.
This means:- F4 = off-time 4 - the Duet default value is F3, the value that was set by Snapmaker was F6. I settled with something in between that worked and "sounded good". According to the TMC data sheet, the value does not play a role in StealthChop anyway.
- Y1:2 Hysteresis start and end values in the chopper control register --> taken from the original Marlin code for the TMC2209 drivers since the datasheets claim those have the same range for both drivers. I admit the code I had to go through was more than chaotic, but I hoped for the best and it... well, worked, that is why I left those values. Again, according to the TMC data sheet, these do not play a role in StealthChop.
- V25 = tpwmthrs: first of all, the TMC steppers do create issues when dynamicly switching from StealthChop over to SpreadCycle, as Oliof correctly pointed out. Since I know that the TMC steppers on the original controller board of my printer use StealthChop all the time, I went to mimick that behaviour and followed the advice from @dc42 given here: https://forum.duet3d.com/topic/22436/missing-steps-cant-print-spreadcycle-stealthchop-tuning-help/131 --> in order to not switch over to Spreadcycle, I set V25 which translates to 375mm/s - which then is high enough never to leave StealthChop mode.
-
@NeoDue @oliof I'm a little surprised that using spreadcycle made the problem worse. Usually as mentioned above spreadcycle is a more "powerful" mode and tends to have less issues with lost steps.
I wonder if any of the custom settings you have (that would then have been enabled) could have come into play?
It looks like you have enabled CoolStep with M915 T1. My understanding of how that works is that with the settings you have the motor current could be reduced to 50% of the selected value if the motor loading during the previous moves is low. I wonder if that might be causing problems with your print?
@NeoDue If you can face another test print it may be worth using the default RRF spreadcycle settings with no special timing and no coolstep options?
Just to explain why I'm asking about all of this... There have been very few reports of this problem from others, this may mean that there is something in your configuration that makes the problem more likely to show up.
-
@gloomyandy Yes, I understand As noted above, I had tried that for the Y axis alone with RC1 (did not help back then), but I will retry right now.
From my understanding, M915 T1 effectively turns off Coolstep, that is the reason for these lines.
-
@NeoDue From my reading of the code and of the TMC 5160 datasheet a value of 1 will be setting the lowest bit of the COOLCONF register which will set the SEMIN value to 1. The datasheet says:
If the StallGuard2 result falls below SEMIN*32, the motor current becomes increased to reduce motor load angle. %0000: smart current control CoolStep off %0001 … %1111: 1 … 15
So a value of 0 will disable CoolStep but 1 will have it enabled. The RRF default is to set the COOLCONF register to 0.
-
@gloomyandy That went fast - tested with the following stepper settings:
M569 P0.0 S0 D2 ; testweise auf Spreadcycle umgestellt. M569 P0.1 S1 D2 ; testweise auf Spreadcycle umgestellt. M569 P0.2 S1 D2 ; Antrieb an DRIVER_2 (Z) läuft vorwärts mit Spreadcycle M569 P0.3 S0 D2 ; testweise auf Spreadcycle umgestellt. M569 P0.4 S0 D2 ; Antrieb an DRIVER_2 (E1) läuft rückwärts mit Spreadcycle M569 P0.5 S1 D2 ; Antrieb an DRIVER_3 (E2) läuft vorwärts mit Spreadcycle
Got the same layer shift in x direction again, this time a little earlier at 2.2mm and aborted the test...

@NeoDue Interesting, though it is a bit concerning though that this seems to be a different layer shift to what you were seeing with your original settings. Can you try disabling input shaping and see if this "new" layer shift goes away?

@gloomyandy That test is already running

@gloomyandy I got the "T1" from somewhere deep inside this forum when we had our last discussion about the topic ( https://forum.duet3d.com/topic/33756/rrf-3-5-0-rc1-shaking-rattling-in-stealthchop ). But thanks, as you put it, it sounds more logical.
Edit: judging from a finger test of the Y motor temperature, the two settings do not seem to make any difference though.
