printing on a monoprice maker select v2, print speed at 50mm/s and all normal settings - says it takes about 9 hours. Why is that if you guys printed in 4? the layer height is .3mm with only 15% infill. any help appreciated guys, cant figure out why its printing so slow. i have a buddy who has the exact same printer and his prints 2x as fast as mine at the same settings in cura. How?
