Thank you for your answers. @Carla_Birch I have not checked Vref, I will try to advise and check. But at 100% flow, it can be seen that the extruder is already pushing very much filament. I calibrated the steps for the extruder to a Creality filament in white. From the default value of M92 E93, I adjusted the step value to M92 E98.27. When calibrating the flow of the same filament, I had to change the flow to 95.24%. Now I have another filamet and when calibrating the flow I got a value of 93.02%. I hope I didn't make a mistake during the calibration. @GregValiant I tried your recommended settings, leaving the line width at 0.4mm. In the first attempt, I left everything original (including print speed), I just adjusted the two recommended parameters. The result was bad. In the 2nd attempt, I reduced the speeds, but there were still gaps in one hole. I don't know what to do anymore. I also attach the Cura profile from the 2nd print attempt. Can you please see if I have something wrong there? Thank you for your help. Profil.curaprofile

@Carla_Birch Thank you for your reply. I tried two prints. 1. Printing. Adjusted the wall width to 0.38mm and I left Flow 93.02%. The result: the gap still made. 2. Printing. Adjusted wall width to 0.38mm and Flow to 100%. The result is significantly better, although a hint of a gap is slightly visible in one circle. BUT, the problem was with the extruder. Flow 100% is already a large flow, because in the 4th layer he started to jump very often when he filled the area. This was followed by 2 layers of 50% triangle filling, which helped to level the excess filament and the extruder no longer skipped. Where else could there be a mistake when making such gaps in a circle? It is strange that he will do this only between the inner line and the fill line. I have an Ender 3 with a motherboard and a basic frimver. Do I have the G-code flavor set correctly? Thank you very much.

Hello. I have an Ender 3 3D printer and I have a problem with the gaps between the inner wall and the top layer fill. Please don't know what it could be? I tried to slow down printing to 50 / 25mnm and also various other settings, but I still can't remove those gaps. Could this be a bug in Cura? Or where can there be a mistake? Why does he only do it somewhere? Will you be willing to help me even if I have an Ender 3 printer? Thank you very much. Tom
