I’m using the ender 3 ke and have started building a lower frame p80 G19 and I have come across problems with my measurements and fills as I’ve tried 2 times already and it has been off or has been looking like a slinky on the end of the rails. I have done them right side up… can I get the right measurements to accomplish this task im using PLA+ too btw. I’ve inputted the measurements from the stl file via cura and need further assistance. Please and thank you 🙏
