As with most of us here, I’m a self taught shopbot user. I’ve been at it for about 9 months now. Today I just noticed that the shopbot software comes with a “Spindle Warmup Routine” in the custom cuts menu. I have never used this before, I’ve always just loaded my part files and started cutting. But should I be warming up the spindle first? What are the benefits of doing so? The costs of not doing so? Who out there warms up their spindle and who doesn’t?
