Larger Nozzles on Flashforge Dreamer

We recently upgraded our two Flashforge Dreamers with Micro Swiss All Metal Hotends and have been getting great results from it, even printing in Polycarbonate with the tiny 0.2mm nozzles! We've been really impressed with the fine detail you can get with the tiny nozzles, but how big and fast can the Dreamer extrude?

Micro Swiss makes all the way up to a 1.2mm nozzle, but given the Dreamer uses a 0.4mm nozzle stock how much plastic can it really extrude properly? Anyone have experience running larger nozzles on the Dreamer, with or without an all metal hotend?

Thanks,
Joe

biggest I've gone to date is 0.5.

The issue isn't really how large a nozzle can you use. But how fast can the printer cool the bead.

I can't see 0.6 being a problem, and you might get away with 0.8.
But you will soon hit the law of dimishing returns.
Ie: because the most important factor is to cool the bead and get it to set as fast as possible, before it deforms under it's own weight.
The bigger the nozzle - the slower you'll need to print.

Unless you add a couple of turbofans and second print area cooler, then 0.6 and maybe, 0.8 is probably your limit. And 0.8 will have to be printed pretty slow.
