After first time setup and initial calibration, this first layer print has cumulative precision error further it goes in printing. I saw this error before but I forgot what cause it. Could anyone help? [20250908_101218]

@sovol3d I revoked “Solution mark“ because I found root cause. Nozzle has wrong offset (my default 3.5mm is off by -0.09mm) and setting it manually in printer.cfg has no effect even when is set from Klipper screen via manual z offset calibration. I used filament gCode override, and I think that pri…

Hello @sovol3d Could you help him?

[image] KoizumiChineko: cumulative precision error I’m not sure what you mean. To me the X and Y precision shown in the photo seem fine. The entire thing seems under extruded, minor for the top left, some worse bottom right. What filament are you using. Even a tiny variation in filament dia…

I doubt it, I’ve just did belt tension adjustment (tutorial below) and frequency was off by 70 Hz, after calibration and mapping I would try print again. I think that was it SV08 AB axis belt replacement and adjustment tutorial

I tighten the belts, calibrated K factor and flow rate. Same issue persist but not as intense as before, so could be there something else I could try?

[image] cardoc: Have you done a “flow rate calibration” for this roll of filament? [image] cardoc: Try switching the solid infill to concentric and run another test print. Did you try these? Might help to sort out the issue.

You can enter the mainsail to view the grid diagram of the hot bed and make adjustments. If one side is high and the other side is low, it may be that the gantry is tilted. It is recommended that you can QGL calibration several times. [image]

I don’t think it’s for me. @KoizumiChineko it’s probably for you.

@mich0111 Yep I think so. @sovol3d I will address first layer issues after my first big print, but despite first layer issues after calibration Z quality is near perfect. I will update soon. [20250909_200121]

ok so this is result after calibration [image] [image] so is anything I can do about it?

Your print seems correct to me. What more do you want?
