Hey, I’m brand new to 3D printing (Christmas present). I’ve printed several smaller objects successfully but when printing larger ones, I’ve noticed in one area the PLA filament doesn’t want to stick to the bed, but everywhere else it sticks great. I’ve re-levelled the bed twice to no effect. I’m wondering if akin oil on the bed could be an issue? It’s always in the same area. If this is the case, what can I clean it with? Or what else could cause it?
My model is a Monoprice 13860 Maker Select V2.
Use Blue Painters tape for play l, works great.
Other options include glue stick, hairspray.
A heated bed will also help.
Elmers purple (dries clear) glue stick works better than the white one in my experience.
@Panayiotis_Savva the bed is heated and it has a surface similar to a plastic mouse pad that’s attached
These are the best method I found they with for me 
+1 Elmer’s purple glue stick. If you have an even coat and still have problems, might be a bed level problem? Don’t be afraid to clean that old glue off. In my experience, eventually that stuff gets too old or globby and prevents a good first layer. Double check your z height settings. And have fun!!
What’s a good product for cleaning off oily substances from the bed? Rubbing alcohol?
I think dishsoap would be an OK place to start. That typical cuts grease and oil well.
@Jonathan_Dagnillo Yes Isopropanol is absolutely ideal. Here’s what I’ve been using for the last year or so (it lasts forever):
