  1. Got a dual nozzle setup on my printer, 0.4 and 0.8mm and want to improve print speeds while not having to use a 0.8mm nozzle for exterior surfaces. What I dream of doing is printing the outer one or two shell with a 0.4mm nozzle, at 0.25mm layer height then another interior shell with a 0.8mm nozzle with 0.5mm layer height. This of course would need to do two of the thin layers for every thick layer, but this is already done for the print infill at higher layer heights so must be doable? How can I do this and if not is it on the horizon for being doable?
  2. Ah yes, I probably should have mentioned I've had a play with that setting but I found it knocked ~10-20% off the print time but not the 50%+ I'm after for it to be worth it. I really need it to also print some of the perimeter layers at the larger layer and nozzle size with just the external wall to be the finer nozzle. - Ideally using the larger nozzle for 95% of the print (inc outer perimeter layer) and just switching for the 5% that needs the finer nozzle such as printed hinges and threads.
  3. Found a few old threads saying it wasn't possible back in 2017 but was wondering if it's now possible to set up a Cura to print 1 or 2 exterior layers with a 0.4-0.5mm nozzle and 0.25 layer height and print the infill and maybe a couple more perimeter layers and the infill with 1mm nozzle and 0.5mm (a multiple of the finer layers) layer height? I'm guessing if this is possible we could then progress to using the large nozzle for most of the print and just using the finer nozzle on threads on other parts that need higher tolerances and finer detail? I print a lot of large parts where detail isn't important over 95% of the print as they are purely functional parts but finding 1mm nozzle quite hard to get the detail on the 5% that needs it - I've tried printing with a 0.4mm nozzle but found the 20h+ print times too long (4-6 hours with the 1mm nozzle)
