Hello community and sorry if there is a same topic in the forum. I want the S3D to extrude filament before a print start like cura do. I achieved to do that with gcode like "extrude 5mm feed stock". Is there a way to do that from the software as default? I added more skirt lines but when filament is extruded before print i have better adhense

Thanks, John

Well what printer do you have? Different printers use different commands, so if you want help, that would be some good info to start with ;)

But yes, typically all you need to do is add 1 or 2 lines into your starting script and then it will run before every print. For example:

G92 E0 ; zero the E-axis
G1 E20 F800 ; extrude 20mm of filament at 800mm/min
