This is probably are very simple question to answer so here it is.
When cutting on a cnc 3 axis router, the feed rate can go as quickly as 80 ipm when cutting wood.
But, when I cut something that has more than 1 axis moving at a time in travel (like a 2 ½ D drawing) the federate goes way down.
In other words, when I am doing straight cuts I get 80 but if I am cutting something with the zed moving at the same time, federate goes WAY slower.
Is this a common thing to occur? What can I do to change this?
I have 2 different machines, 1 stepper and 1 servo and they both do the same thing.
thanks,
Steve
