Strange artefacts (motors vibrating)

Hi,

I have smoothie-board v1 with the latest firmware. Core xy config
I have a strange artifacts on my prints. See the image

This started some time ago and i don’t remember what I’ve done (or I did not) to trigger that problem.

I can hear and feel the motor vibrations cause this artifacts.
I’ve tried to downgrade the firmware. I’ve tried to create a new config file from scratch using windows notepad (not notepad ++ or similar). I’ve tried to play with motor currents and junction_deviation .

Regards,
Matija!

That looks like the wrong image.

(Note that if you put a link to an image on a line of its own, the image will show in your post, including in the preview that shows while you edit. I edited your post to move the image link to a line of its own. You can also upload images here, as well as post links, whichever is easier.)

You can also paste your config between ``` lines, like this:

```
Your config file goes here
```

Thanks on your edit.
I don’t understand your’s comment “That looks like the wrong image.”
Now i can see the preview of the image. But it’s only a fragment of whole image. When I click on the image, the full version opens. When you click one more time, the full size version appears. On the image is black printed part with those strange artifacts.

later I’ll post my config file.

Oh, that looks like the google album is defeating the “onebox” that tries to display it. It would be much easier for people with smoothie experience to be able to actually see the problem without guessing that they have to click twice. Can you please upload the image (or multiple images) here along with your config file when you upload, to make it easier for people to help? (I’m not a smoothie expert, I just help run the site… :slight_smile:)

Here;

And here is my config file

Same issues on X & Y?
Try pringing a cube at 45 degrees angle to “isolate” the motors. (Since you have a CoreXY)

I had similar issues and found it to be the extruder that was causing the issues for me…

As for your config, i’d suggest you lower the current for the motors and see what happens. You already have quite low acceleration so shouldn’t have to use that high current unless your gantry is really heavy. Also look into lowering your junktion_deviation. 0.05 is default i think.

Thanks Saldo.

I’ll try in a few next days.

Hi,

as SaldoT suggested I’ve tried to print a cube. Well not a cube but a hexagon so i’ll have all combinations. And the results are;

  1. When both motors are working with same speed (for example for the parallel wall to x or y) there are no vibrations.
  2. When one motor is working and other stand still (for bottom layer the lines are at 45deg) the vibrations are the worst.
  3. When there is some combination is motors speed like printing wall of hexagon at 60deg, the vibrations are present, but not so terrible as when printing lines at 45deg.

I’ve lowered the motor current to 1.1, and junktion dev at 0.05

My thought was that one of the motors were causing the issue but that doesn’t seem to be the case.
I can’t think of anything that would result in the errors when you’re running only one of the motors but no issue when both motors are running. Doesn’t make sense to me… So i’m afraid i don’t have any suggestions on how to solve it. =/

I think I’ve found an solution.
I cleaned all moving parts and oiled them. Although I’m using Igus drylin bearings. After that everything is ok.
Why the problem was noticeable only when both motors were working. I guess that had something with the forces direction of the core xy system.

Regards,
Matija

Igus rails are designed for low speeds ( though their sales guy will come to your home but won’t tell you that … ), they have all sorts of problems at high speeds, bought tons of their stuff and had to replace most of it with proper steel/ball rail systems.
