I have a monorprice maker select V2 with the all metal Swiss hotend, glass bed, etc. I did a print Saturday that turned out perfectly. I was making a mask and I set the second part to be printed over night. When I checked it, it some how pushed nearly all the print off the build plate and appeared to have stopped retracting. I tried all day Sunday for a print of a face shield and it failed into spaghetti every time. All the settings are the same as the successful print on Saturday. Bed has been leveled, extruder cleaned and cleared. Has something else become calibrated? The first layers of prints have been turning out fine later on in the print is where it fails. I am using Cura for my slicer.
