Solved 3.5.0rc1: Input shaping causes layer shifts!?
-
@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.
-
@NeoDue I was seeing major layer shifting on 3.5.0-rc2, like an inch or two at a certain height consistently on a certain print I was doing. Going back to 3.4.6 resolved the issue. Seems like there are still some major kinks to work out in rc2. This was on a railcore II with a duet2 wifi and duex.
-
@skrotz Thanks for the information! I guess your message saves me from re-testing with 3.5.0rc2 for now, at least until the Duet team asks me to do some tests.
I am aware that it works with 3.4.6. But I am afraid going back is not an option for me since I use some of the new functionality introduced in 3.5.
Thus, no input shaping for me until this issue is resolved.
-
@skrotz One more thing: it might be great to keep / post the affected print file and your config.g from when the issue happened here to give the Duet team the chance to take a look at these files as well.

Github issue:

@NeoDue and @skrotz please can you both try the firmware at https://www.dropbox.com/scl/fo/8mwsfwo61tacbyxsu39j9/h?rlkey=zwyd8luhpj7hnanldm4rzm5om&dl=0. If you encounter any layer shifts, then to help me track down the cause please report the following:
- A M122 report taken after layer shifts have occurred. Don't run M122 more than once unless further layer shifts occur, because each time M122 is run it clears the data it reports, and I want the data that may relate to a layer shift.
- Your config.g file
- What M593 input shaping command you were using, if it isn't in the config.g file
- What height the layer shift(s) occurred at
- A link to the GCode file you were printing.
Also please verify that you don't get layer shifts if you do the same print with input shaping disabled (i.e. M593 P"none").

@dc42 thanks! I might only be able to do that the coming weekend, but I definitely will as soon as I can!

Made test print with your rc2+ firmware. Layer shifted at 16,05mm
I didn't get M122 directly after layer shift, I did it when I disovered it.

@vaike_peeter do you have a spec sheet of your stepper drivers at hand?
-
Z-motors - LDO-42STH40-1684L300E
A and B(x,y) motors - LDO-42STH48-2004MAH
I already checked current if you think that.
-
@vaike_peeter with your .9 degree steppers you hit like 48kHz step rate per axis on CoreXY with 16x microstepping. You should get fine prints dropping down to 8x microstepping and giving more headroom for additional computation like IS.
There are some other considerations like maximum RPM and torque that you may be hitting with the 2004s. Check the back emf calculator and the TDS of your steppers for the physical stepper limits too. https://www.reprapfirmware.org/emf.html

@oliof
I will test this when I get back home
-
FYI had something similar happen this night on a machine running just closed loop motors.
Just installed the RC2+ and will see if it happens again.
Already sent this to @dc42 directly as well. -
@dc42 just to make sure since I have no experience yet with the test firmware versions you provide: On my 6HC with no further addon electronics than the PanelDue (a clone, as already noted somewhere here in the forum, since the original PanelDue has too large footprint for this printer - I would have used the one I already own otherwise) and the Wifi module I just need to upload and install Duet3Firmware_MB6HC.bin - correct?
-
@NeoDue said in 3.5.0rc1: Input shaping causes layer shifts!?:
I just need to upload and install Duet3Firmware_MB6HC.bin - correct?
Correct!

@oliof That was really good hint. My test print came out without layer shift. Will continue testing but seems promising. Thank you.
Now X and Y motors are configured 8 microsteping with 80 steps per mm. -
@droftarts thanks! But I fear I need to report that did not work as intended at all - the last information I got from the DWC was that it was updating the board firmware... and now I am having a dead printer. I fear I need to work my way to the Duet in the printer and do a restore via USB this weekend instead of doing the test. Now where was the website explaining that process, it has been ages since I needed that...
