Hello, I'm getting a lot oozing prior to a print. This is leading to strings and drags in the first few layers. Others have recommended entering a retraction code at the end of the print. How do I do this? I'm using Repetier-Host and slic3r. Do I just insert the G-code line: G1 E-1.2000 F1800 After the final G92 E0 line in the G-code? Thanks, Johnby Jmiceli11 - Prusa i3 and variants
