Hello.
I just purchased a 4040 CNC machine with a 300w spindle. Because the spindle is low-power, i'm worried about burning the motor out. Say if I wanted to make a sign like this. Should I remove 1mm per layer? What would my ideal feed rate be with a 1/2 diameter V bit, connected to a 1/8 er11 shaft?
How deep can I cut without straining the motor?
My warranty is only good for 3 months, but i'm going to try and get a year out of this motor, so I don't want to run it at 20000 rpm and burn it out.I want to use softwoods like pine and spruce.
