Hi, I don’t have any STL files editor so the only way I find to print the piece up to a desired height is by adding a post processing script, Pause at height. But it didn’t work.
Am I missing something?
I’d appreciate any help.
Hello @rva1945 …! 
Welcome to the Creality Forum…! 
If you are using Creality Print 5.xxx you could just put in a pause where you want the print to end…
Right click to get that menu…
My printer is Ender 3 V2 NEO.
