Hi All,

I recently upgraded my M2 to the Dual v4 Extruder setup. I'm only using the left nozzle at this time but i noticed a big difference is the print quality using the same Slic3r settings as i was with the older v3b extruder (see picture). I'm fairly certain the bed is properly leveled but i'm not sure what else could be the cause. Any help would be greatly appreciated.

More details on what you have done for calibration?

adjusted your multiplier?
Z-Offset adjusted?

Should i reduce the multiplier or increase it? i think it was set to 1.0 in this photo but I was thinking about changing it to 0.95. The z offset is set to 2mm but should i decrease it to 1mm?

there's no "doctors orders" on how to set those, its a process that is described well in this calibration thread:

This is Awesome. Get to pull out the ol' calipers tonight! Thanks!!

yeah pull them out and keep them handy. Dusty calipers are wasted calipers

Yes its a totally different hot end setup. Your v3b settings wont work. Everything needs to be retuned for the v4.

I was able to find some Slic3r settings for the v3b that someone was able to dial in pretty nicely. Do you know of anything similar for the v4 duals?

The sluc3r user base in the m2 crowd is a bit limited. I have no info for you on it. I only use s3d

Temps are different between the two aren't they ? Seems like some people had to change printing temperatures slightly. My v4 I run pla at 180 . On the v3b it was 210.
