Re: [Emc-users] The sound of G1 vs G33 moves

Yes I'd expect it to sound different. You are asking the the Z motor to do different things in each case With G1 you are commanding an average speed over the length of the move. With G1 it is the total time needed to get to the specified point that matters. The controller will ramp up the z

[Emc-users] The sound of G1 vs G33 moves

In an effort to optimize our lathe for spindle synchronized motion a question came up. Should a machine sound the same when running a G1 vs G33 at identical feeds and speeds? When we spin the spindle at, say, 800 rpm and command a G1 move in Z at 80 ipm the machine sounds different from a
