hello again, I am having problems with my print staying on the plate. I have done the following: leveled the bed at least 20 times. a single sheet of paper just grazes the nozzle of the extruder at four of the five locations. The center location is always a little lower. I then run the auto level which completes successfully. I have tried every combination that I can think of for different heats. I can get about 60% through the rabbit demo file before it breaks free of the bed. this is using the filament that came with the printer. The settings that get me that far are nozzle 195, bed 65, and it doesn't matter if it prints at 100 or 200. The area has almost no air circulation. I have tried as high as nozzle 220, bed 75, and as low as nozzle 175, bed 50. I have pretty much tried every combination in between an increments of five degrees. ambient temperature is around 80° Fahrenheit as I shut off the air conditioning to reduce circulation. most of my attempts fail within the first two layers. I also clean the bed with isopropyl alcohol between each attempt. what should I try next?
