It goes more worse....
Hey folks...
I rly don't know what to do..
(RRvc4 hybrid 400)
I redo already the belt span... And measure it correctly...
Solution:Jump to solution
Okay folks... After a bit of research in my config files I found that the two Y motors was running at different amps.... Dunno how it happened...
I reinstalled ratos because I did not get any access to the configuration tool...
So I fixed the main problem with corrected settings on the motors......

Just stepping in her,... Could be a slicer issue? Look at the preview of the slicer and see if you can correlate what you see in the print vs. Flow, preview, speed preview, fan preview, etc?
hey thanks for that input 🙂
i can see bit of speed changes on the outside like the "marks" i just run a test without that limiting layer time factor and post a picture after it ...
I would say a bit better than before... But still ringing...
I think my rail guide seems to a bit loose or is that normal?
Difficult to see how hard you are pushing to make the gantry move. I assume you have VERY THOUROGLY checked that all bolts are tight? Also. did you do a belt tune with the realtime analyser?
The ringing should be less with a proper belt tune and shaper calibration (shaper_calibrate). Did you do a shaper calibrations?
I was more reacting on the horizontal lines. Did you do pressure advance with these speeds and filament?
yes screws are all rly tight and checked....
and also did my best to tune ...
i also calibrate the filament...
also tried some other filaments with the same result's
but i think specially in this case i need a bit increase PA that's true
Left one ist with my RR and right one with my Voron...
Ringing/ghosting might possibly be caused by excessive belt tension, right?
But I don’t understand the horizontal layer lines that only appear on the X-axis... especially since they are not present on the Y-axis, apart from the ghosting.
Too tight or to loose,... belt tuning is an art... I had my RR31-300 WAY too tight for months... now I tuned them (with the extruder EXACTLY in the middle of the gantry) with both belts, left and right of the gantry at 95 to 100HZ and it prints way more quite and precise (i think you can be between 95 and 110 Hz). Previously I was more at 150 Hz or higher.
I do not see a lot of ghosting or ringing. I do see Z-bands and they are both on X and Y axis. (see red marks). This should be resolved with hardware, but it could be exagerated by a slicer "issue". If for instance all layers (below the red marked layer) are printed Clockwise and the layers that stand our are printed Counter Clockwise, you could see this. It could be your nozzle is not tight, your hot end is somewhat lose, play in your extruder or mounting of the extruder, your whole extruder-assembly is lose, your belt might be going up and down on the idlers or motor,... (I have been fighting such in issue for 2,5 months after I disassembled/reassembled the printer to check the frame for squareness).
Your shaper graphs look nice to me (better than mine 😉 ).
(Guiter-stands I think 🙂 ?)
You might want to call out in #fix-my-printer with a reff to this thread (no cross-posting obviously)
"realtime analyser" was a good point... i dont got any acces to it or the configurator... seems i fkt up RATOS... (reinstalling it first now...)
Yes, if you have Ratos 2.1 rc3 (which is very stable now) the realtime analyser takes all the gueswork out off tuning the belts.
This isn't ringing or ghosting
This is ringing/ghosting
What you've got is Z banding, as Arthur mentioned
It's very unlikely to be due to your Z axis kinematics, it's too inconsistent and you've got oldham couplers.
So I'd wager it's inconsistent extrusion.
