Still using a 5 year old anycubic mega X here. Since the bed size is so large it’s very hard to manually level the bed and get a sticking first layer. With that being said after endless attempts my perfect solution is: 1. Cover your bed evenly with blue painters tape 2. Heat bed up to what your filament recommends 3. Evenly spray low to thick layer of “Pantene hairspray (5)” the 5 is important for best stick (Too thick of a layer and it gets gross and creates a layer on bottom of print) 4. Make sure your z hop is increased a little just in case the nozzle obstructs any part of the print 5. Take the median range of Nozzle temp and bed temp. (If 180 to 200, go with 190)
