Yep, I’m familiar with the minimum layer time. That doesn’t help if you want to have strong parts and to print fast on a large format printer. The recoat times of layer to layer make a huge difference in strength of the part. Ie: I make a large part and it takes 1 minute to start printing in that same spot again vs having a maximum layer time of 30 seconds, then the printer would speed up to make 30 seconds. This is really important if you are printing with semi-crystalline materials. I tensile test these results at work at different layer times and the results change a lot. The part may look the same if you are just trying to make a pretty part, but they are totally different for structure. Does that make more sense?
There is the opposite, there is a minimum layer time, which helps if you print small objects to give the layer enough time to cool down.
To specify the maximum layer time makes no sense to me.
