UM3 Dual Extrusion with 2 Different Size Nozzles

Wondering if this is possible? I would like to pick up the new 0.25mm AA print core but don't want to lose my ability to print with PVA.

Pretty sure it works.  Someone told me he did 0.8mm left core with pla and 0.4mm right core with pva.   Also I know for sure someone who used the left core for shell and the right core for infill.  You could play with this in cura before you buy anything.  There's also the option of getting 3dsolex cores which allow you to swap out nozzles.

I was wondering this too.  I imagine that it should be possible, as long as both cores are printing at the same resolution.

You can print with 2 different size Print Cores as long as you're using the same layer height.

My regular print routine is PLA using a .6 3DSolex AA core and a .4 BB Ultimaker core for PVA.  Just tell Cura the correct line width (I use .53 for the .6 3DSolex AA core).  Been doing this for more than a year now.

I use the 0.8 pla laft + 0.4 polysupport right, works fine, just remember that layer height range is limited.

yes this works just fine!
Be sure to remember height difference.

Successfully using PLA 0.4 in Extruder 1 and PVA 0.8 in Extruder 2.

However, I must override the warning/error msg from the UM3 that says different cores being used each time I print.

 

Can this be a preference option so that we don't need to override each time?
