Hi,
I am just finishing building a small tool post sat on top of a stepper on my cnc based rose engine. The idea is that when I cut a pattern on a curved surface I can rotate the cutter so that it is always normal to that surface, the allowable range would be 0 - 180 degrees.. I need to buy a controller and was was looking into the new digital ones such as the DM320C from Zapp. I understand that you can program the micro-step revolutions so I am wondering how this is achieved. Also would it make sense to set the micro-step to 36000 pulses per rev or 0.01 degree per pulse, is this possible.

Anyone done this yet?
