I'm new to this forum and am using Mach3 with my homebuilt CNC routers. I am writing to ask if Mach3 supports anything other than a trapezoidal velocity profile. With the standard profile, even though I've decreased my accelerations significantly, I still experience a fair amount of jerk (2nd derivative of velocity) that could be reduced alot with a simple sin/cos (S-shaped) velocity profile. Does anyone know if this is possible with Mach3? I've searched google, and these forums and haven't found that it does so thought I'd pose my question directly. If not, how do I go about requesting this feature?
Thanks.
