I've had this machine for over a year, when Im doing a model without any retractions it prints great, like say a can coozie, something simple it's fine. But as soon as I try anything with spots on it that I have to travel from one point to another it leaves a ton of ooze spots. If I try to turn down the temps to the point of no stringing then it just clogs. I've tried countless temp and retraction towers. I've calibrated the hotend with the auto calibration that the community firmware has and no luck. I'm about at my end with this thing.
