Recently I have been using a Prusa I3 MK2. I really like how it does a purge line right before it starts to print at the very front left of the build plate. I think that the Mini would really benefit from this type of command. Even if you preheat a Mini and extrude filament before it is started, by the time it goes through its whole start up process, the filament often times has trouble coming out. This obviously differs in severity by different types of filament, but it seems to be a consistent issue. I think that a purge of filament at the end of the Mini’s startup process would really improve it’s success rate. The heavy duty purge that the Prusa does is way more effective at getting the filament going than the outline skirt that most slicers do.
I looked at the scripts tab of S3D for the Prusa and see the following:
G1 Y-3.0 F1000.0 ; go outside printing area
G1 X60.0 E9.0 F1000.0 ; intro line
G1 X100.0 E12.5 F1000.0 ; intro line
Would it be as simple to add this to the Mini’s script? Would I need to alter it at all?
