hello to improve concentricity, when driling with M axis, is good to also spin the spindle; please, is there a recomandation for main spindle rpm, in relation to live tool, or something that is good to know ?


if you switch from auto or mdi to manual, the machine resets ( rpm stops, tool offset is gone ); but why doesn't it reset if i switch between auto to mdi, or viceversa ?
... in auto mode, i can press mdi and program will continue; however, i can't input anything in mdi as long as main program runs in background
... in mdi mode, i can switch to auto, but i can't select a program, until i press reset, otherwise it will throw an error

please, is there something about switching between auto - mdi ? or is it possible to activate mdi during auto mode/mid-auto, so to test a random code while the machine runs the main program ? kindly
