Clearly the value for G0 is different than that for G1.... what value do you have for G1?

Maybe I should make the spreadsheet deal with different speeds and accelerations for G0 and G1 and estimate the motor power based on which is worst case... As stated the value of 0.02 will produce an overestimate on the motor size for large routers or table-based machines but isn't too bad on a small lighter machines
