And because of the extruders flow limits, a taller layer wouldn't gain much time as you'd still have to slow down to allow the extruder to keep up with PETG. Time to bond before cooling was improved quite a bit by slowing the side fan to an idle speed, I just made the best bearing carrier I've made yet by essentially turning it off. And I'm ploting how to fix a baffle on top of the hot block to keep the front fans cooling air away from the hot block. Those hot ends that have the fan clipped onto the heat sink look like a better idea. Still looking for a 2 bolt mount that does that.

Thats quite a bunch of layers if the part is 40mm tall. > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
