I'm new to the forum and the M2 will be my first 3D printer so I'm hoping some of you veterans could give some tips on the M2, its scheduled to ship next week.

- I've read that with a heated bed you shouldn't need to use tape with PLA filament, is that correct? How about glue, hairspray, etc., I've read many conflicting views but maybe somebody who specifically owns the M2 could describe their experience?

- When printing a large flat object should I use the raft or ok without it? I've read its not needed with PLA?

- I guess this is probably more of a CAD or slicer question. If I have a model, for example that has a bore hole for a screw to go through. Is there anyway to have the printer reinforce the wall just around those bore holes? I'll be using Simplify3d. I know you can have separate profiles for different levels of the model, but is there a way to specify just certain features like the bore hole for reinforcement?

I have lots more questions, but these are a good start I guess for a noob.

Thanks!
