Duet 3 mini X axis weird sound at decel
-
Hi,
Since I've switch to duet 3 mini, i got a weird sound at decel on the X axis at high speed that sometimes (i think) cause layer shifts, Y doesn't even if it have same settings.
I thought in first place that it was the M569 V parameter that was too high but even at 1 i have this sound, in spreadcycle i haven't this sound but it's a lot louder.does anyone had the issue and resolved it ?
Here's a video if you want to listen https://drive.google.com/file/d/1-kVhqiigsvg7bo2yxqshgJVfqGPtCCtb/view?usp=sharing

@krohm-koala please post information about your setup, the config.g to show what motor currents you are using, input shaping in use etc. I would expect Y to be different from the X on a bed slinger.

@t3p3tony i have a MK3S bear, i run the same settings on X and Y motors, that's why i don't understand the problem. Here's my config.g

@krohm-koala I think V1 on the M569 commands for D3 is quite unusual
have you followed this:
https://duet3d.dozuki.com/Wiki/Tuning_Stepper_Motor_Drivers?#Section_Configuring_stealthChop
As a comparison try the default (M569 Pn Sn with no other parameters ) for the X axis. -
@t3p3tony I haven't tried to follow this but looking at it, i don't think i'll help. Default V parameter make the change to spreadcycle at 1.9mm/s.
V1 on my M569 was to be sure i don't go in spreadcycle and that wasn't the cause of the sound, i run it at V15 (250mm/s) usually, as i tried to go as fast of my duet 2 (i was able to print my infill at 200mm/s and can't anymore) i'm searching for what limits me for achieving that speed and principally what makes the sound as it didn't in spread cycle.
Do you think the motor can be faulty ? -
@krohm-koala not sure about the motor, can you easily swap them?
-
@t3p3tony at first i'll just swap cables from X and Y, it's not complicated to swap X motor for another but i haven't one with same specs in stock and swap both motor will be a long job with the tensioning etc. If i need to go to this step, i'll do
I'll come back to you for the result. -
@t3p3tony So, at his time, i've done some tests, i've swapped cables with no change, i've change the cable and even used another driver, same thing, i reduced and augmented accelerations and same with current, still no real change. I also have just wired an other motor, it seems to do same-ish things without even mounting it. it's really weird that just this axis does it, i think i'll end my search for speed ^^
-
Search for speed and using stealthchop aren't really compatible. If you stay in spread cycle does the sound go away?
-
@phaedrux yes it goes away but I had some layershifts when the driver switched to spread cycle during prints, and keeping it spread cycle the entire time is louder, i should try since there was many update since I've tried having it switched, maybe also bad config, I don't know, switching was loud and sounded almost as what I experience now.
