I seriously hate this leveling system. Can never get it right. I see why they went away from it in new versions.

I just upgraded my M2 to the single v4 extruder. Luckily, it works! I don't really notice a difference yet from the v3, though I'm using the exact same settings. Are there some recommended settings for the v4 to get the best prints at a good speed? I want to take full advantage of this new hardware....

cool good to know, thanks for the replies. Maybe since I'm new to this I'll go with the single v4 upgrade for now. Thanks!

I found the merge all outlines setting, where is the perimeter settings? I'm pretty new to this.

I'm trying to do this exercise but for some reason Simplify3d only wants to print one of the four walls (of the .4mm thin wall). Anyone know how to get it to do all four walls? Here are my settings, based on rsilver's high quality settings: https://dl.dropboxusercontent.com/u/3098507/3d/M2HighQualit...

My prints are all having the same issue: the first few layers are printing too small. Initially I thought it was printing right and then warping, but after watching it closely I realized it's simply printing wrong and then correcting after a while. What could be causing this?

Do you need the dual extruder in order to print supports (generated in Simplify3d)? Or can the single do it? Also, what are the other advantages of having a dual extruder?

So I just got my M2 a month ago and noticed the v4 extruder is available. Is it pretty easy to upgrade? Also is it compatible with the dual extruder component? Or does the dual extruder include a v4 as well? Thanks.

hmm, must be something funny with that gcode. I imported a stl from thingiverse and it's now printing just fine! This is incredible!

Here's my machine settings:
