How do I set up a .6mm profile and .4mm profile for the same physical printer?  

RE: How do I set up a .6mm profile and .4mm profile for the same physical printer?

Let me clarify that.  I have the profiles set up in Prusa Slicer, and both printing across the network, but I don't see how to have the two profiles on the Prusa Connect web page.  If there's a simple way to set the nozzle size in Prusa Connect, then that would work just as well.

Hi, you posted under the wrong category, this is more PrusaLink and Connect and less PrusaSlicer studf. I'll move it to Prusaslicer. I know I was trying to do the same thing but I'm not at the PC right now. I'll get back to you tomorrow. Sorry

It was already under "Prusalink and Connect".  You said it was "less PrusaSlicer stuff" but then said you'll move it to "PrusaSlicer", lol.  I'm sure you'll let me know what you meant.

Thanks for getting back to me.  This was giving me a real headache!

Hi Jeffery, 

I think you have ended up in the right place... 

Prusa slicer (PS) needs to know what size nozzle orifice you are using.  (set that in 'Printer settings > Extruder) use the actual value e.g. 0.6mm
then PS needs to know how wide you would like the extrusion width to be... (Set that in 'Print Settings > Advanced' there are a number of parameters,)
in most instances the extrusion width is wider than the actual nozzle, to promote  squishing of adjacent printed traces. 
exceptions usually are

'Support' where the extrusion width is normally slightly thinner than the nozzle diameter, to promote weak bonding,

'Top infill' which is usually the same as the nozzle diameter and 'first layer', which is usually a little wider than the nozzle diameter, but narrower than the other extrusion widths. 

For prusa printers there are ready made profiles which can be selected in the configuration wizard under the configuration drop down menu
If you have a different printer, then you may be able to 'crib' the extrusion widths off a prusa profile for the same nozzle size

then layer height is limited by nozzle diameter, you should never exceed 80% of the  nozzle diameter....  so with a larger nozzle you may be able to use a larger layer height. 

Then there is the issue of How much filament can your extruder melt?   
If you use large extrusion widths with fast speeds and thick layer heights it is possible to run into problems with the amount of filament that you can melt, this value is a factor of what hot end you have fitted to your printer, what filament you are using, and what temperatures you are using.    there is a variable in 'Filaments > Advanced > 'Max volumetric flow'  ' which controls this feature, and this effectively monitors the use of filament, and slows toe print speeds if there is a risk of exceeding the max volumetric flow.  

the type of filament in use can also change the speeds that you should print at, TPU and PETG generally print slower than PLA for instance
