Someone please educate me on how I can make PETG stick. I'm using a Monoprice Maker Select v2 (Duplicator i3) with the stock bed lined with painters tape using hairspray. I've got a fresh nozzle, fresh PTFE tube in there. I've tried temps from 215-250 extruder and 60-80 on the bed. I've tried first layer speeds from 10 mm/s to 20mm/s. I'm using Amazon Basic transparent PETG. I cannot for the life of me get it to stick. I've leveled and releveled my bed putting it close and a little further up as I've heard petg likes a little more distance from the bed.............i'm out of ideas. It just rolls up and clogs up on the nozzle. The PETG is relatively new, could it perhaps be the material? Please help. I dont use the fan on the first layers either.
