HELP!!! I have an Ender3 V3 KE , I love it.. But I have a problem. The last few models after it gets past the base and is doing the infill, it scrapes over the infill. if I adjust the z axis, it stops for a few levels. If I let it go it does get worse. I've also adjusted the print speed, paused the print to check the hotend for tightness. I'm afraid that if I let it go to long it might break the model loose from the print table. Thanks Philacop1
