So when I print models strait from thingiverse my printer will print them. Initially my model did work when I did a mini version of it. I enlarged my model to about three times the size but when I did this my printer won't print it. It moves as if it knows where to print but it just stops extruding. Once in a while it will extrude stringy filament but it' looks like it's out or it only lets a very small amount through. Only things I mess with on cura is line height and width. Does anyone know what in my slicing options could cause a model not to print? Been working on this for a week and it's getting frustrating. Maker select v2 is my printer. 215 print temp 60 bed temp. Again it prints the skirt almost perfectly. The very start it misses the bed after starting for a second but I clean the single string and it finished the skirt without issue.
