It does feel like that. im using a ender 3 pro too.. I tried the Stock bed, the microporous buildtak and finally glass superheated. it works well and pops off once cold. i use 245 Inital and 220 for the rest as it seems to have zero stringing when its cooler. i can feed the petg through the nozzle as low as 180!just trying to fix the issue of small detailed first layer from sticking to the nozzle. the feature in cura which means the quick change in direction is slowed down seems to work well. ive got that set at 0.5mm/s as soon as intial layer is done i go up to 50mm/s and it prints lovely. i also level the bed using a BLtouch which is calibrated with a feeler gauge to exactly 0.2mm. so when it reads zero the nozzle touches the bed! PLA printed like a dream on anything, god i love PLA
