i think it would be a great if 0.8kw, 1.5kw, 2.2kw, 3kw / 24000rpm/ machine presets are included for the most popular chinese water cooled spindles. I have 3kw/ and 0.8kw/ and for the moment am using the Mcmaster router preset to 18k rpm.
These 4 have no documentation about torque curves, so should be found from similar brand ones. They are the defacto DIY spindles everybody around the world uses for a router, with 0.8kw like most popular in small machines, 2.2 for woodworking and the 3kw for people that cut aluminum or have stronger machines.
I think these presets a very needed. If i knew how to do it properly, i would have made them, as i need the 0.8kw and the 3kw one all the time.And i know of at least a couple of people that use the program and have 2.2kw machines
