my cnc knee mill ran on a mectronix card 8+ hours a day for 10 yrs, and the folk who built it had the oiler run about 8x a day for about a minute. this is a good discussion for making the software maintain a schedule you can decide on. but I lived with the consequences of their 8 x 1 schedule which was excessive oil on the ways and on the motors and in the coolant. when/if I get this thing running again on either mach or uccnc, my oiler system will be set to run once a day on turn on, and if it is a programming pita, I will leave it out, mount a spring loaded button on the oiler, and hold it down for 30 sec every morning I run. yes the ways need oil. most of these machines here could live with an oil wipe by rag every morning. sometimes the best way to work is k.i.s.s. jmho, ymmv.
