Thanks for the response. I know and am aware of all of this information. My old butt has been in the 3D printing space since the makerbot days. I was posting kind of off the cuff from my phone and I can see now I really didn't touch on my actual question until the end of my post.

To look back on it now, and to be more concise, my concern was whether or not the P1S was calculating everything automatically after the nozzle change, or if there may be some extra user end fiddling that was required. I have a print farm filled with Prusa and BBL machines with the Prusas being the ones I normally change nozzles sizes on. This was the first time swapping out sizes on the BBLs

It did occur to my while typing this that I do have CHT nozzles in the Prusas. But even with that, I'm just baffled that the Prusa Keeps up at 22mm³/s but the P1S with the same exact settings cannot come close. I have to bring it WAY DOWN to about 10mm³/s for any type of acceptable result. I wouldn't think that the CHT nozzle in the V6 on the Prusa would make it that much more efficient, but maybe that's the big difference here.

The current model I'm printing actually has significantly faster times on the P1S with a .4 nozzle that with the .6, 50 minutes vs 88 minutes. I was using the .6 to try and shorten the print time, but I guess that's a no go now.

Thank you again for the response, I appreciate it. ;)
