View 3D Printer 2Nd Layer Problems Pics. Open generated gcode with cura. Incomplete top layer fills, top layer holes/gaps.
Print edges are bending if the problem starts with a new printer then the likelihood is that something is amiss with the printer's configuration.
I print petg without cooling at all, and never had problems with delamination (although it won't bridge as well). Double check the printer's construction and alignment. Add printing media below this area if the overhang is too difficult to manage for the 3d printer. Actual results 2nd layer is bigger than others, causing elephant foot when printing, tested on 4.7.0 and 4.6.2 with several stl.
