core x y stepper noise

Aztazticz

It has 6 stepper drivers. I will be using all 6.

But just for another test I swapped the extruder and the problem driver and re connected all ssteppers and printers movements are smooth and quiet.

But I’m afraid running the extruder on the problem driver will inflict extruder issues

@Aztazticz I'm just an end user like you so I have no authority but it does look to me like you have a faulty driver. You have proven that if you plug the offending motor into a different driver, the problem is fixed. Hopefully one of the Duet team will see this thread and react by authorising a warranty replacement or suggesting some other tests that you could try. If not, email the vendor or Duet3D directly and draw their attention to this thread.

EdIt. Just one thing. @Veti spotted an error with your drive mapping for the Z motors that I had missed (see his post above). Did you put that right? If not, do so and double check that you still have the problem.

Same Duet2 problem here. I have two Y steppers and they are noisy unlike X stepper.
Y steppers were connected parallel and serial, no change.
Maybe I change Y driver to E1 driver. Can't stand the high frequency noise.

Pertti

I tried to change drives to Y motors, even different drives to each but no change in Y-noise.

Aztazticz

@deckingman Yeah i fixed that, it made no difference. even though there was an error, my 3 z steppers were still functioning correctly with g32. either way, config should be correct now.

anyway cheers for your help, its up to my vender/duet now i guess.

@Pertti said in core x y stepper noise:

If you will continue isolating the problem, it will help you fixing it. For example:

Does it works better with another driver?
Does it make the noise when you hold the motor suspended in your hand?

Pertti

No change
Haven´t tried

Pertti

What I tried was that I connected the x-stepper to the Y driver physically and vice versa. Now the noise changed to x-stepper. This speaks that the signal from the Y-drive is noisy.

@Pertti Perhaps best to start a new thread to avoid confusing the original posters issue and troubleshooting.

Pertti

@Phaedrux OK!
