Question No. 2

Hi all, Do all cnc programs have provision for closed loop feedback
from encoders? as I guess this takes care of missing steps. I'm
planning to build a small mill to cut clock plates & cross out clock
wheels, I expect the available table force to be in the region of 200
lbs., this is more than enough to break any end mills that I will be
using, so maybe missing steps won,t be an issue. (Adding encoders is
obviously a lot of work if the general opinion is that open loop will
be O.K.) Thanks in advance for any comments, as always they will be
valued & greatly appreciated. Ian Sutherland.
