I guess I have something to do later today. ---

Looks like a newer version of the printer as the spool holder is on the side instead of the back as in the V1.0. ---

> [@Lion](#): > > It could just be a print, it’s what I did. It’s not. Look where the spool holder is attached. There’s no print and there aren’t any screw holes in that location in the model we both have. The Z rail and it’s aluminium extrusion profile however is behind that spot which would explain where it’s been now attached to. ---

Mine was fine, I didn’t have to make any adjustments. ![PXL_20250612_185134757](https://canada1.discourse-cdn.com/flex030/uploads/sovolforum/original/2X/b/b2a0376e62f2c05bf269e7e0422caf3c75ad53a0.jpeg) ---

Thank You – to those who contributed to this thread (OP, Cardoc, and Vergo). I had gone through calibration and still had significant print quality issues. Correcting belt tension and re-running input shaper/resonances made a significant improvement. I had trouble with the app, so used a 3d printed analogue tension meter (**[here](https://github.com/Diyshift/3D-Printer/tree/main/GT2%20Belt%20Tension%20Meter)**). Good Luck. ---

Ringing/ghosting issues are often tied to vibration and motion settings, so the suggestions about belt tension and input shaping make sense. One additional thing that can help is running a simple test print after each adjustment instead of changing multiple things at once. This makes it easier to see exactly what improved the quality. Also, try [printing a test](https://myprinttest.com/) pattern with straight lines and sharp corners, as these usually make ringing more visible. It’s a quick way to confirm whether the changes actually reduced the vibration artifacts. If you want a quick reference, using a test print page or pattern can help you consistently check print quality after each tweak. That way you can compare results step by step instead of guessing what worked. [Previous page](https://forum.sovol3d.com/t/print-quality-issues-ringing/7866.md?page=1)
