preface.....just replaced my (leaking) oil-free 30gal compressor with a new oiled 30gal compressor. no change in Amp or Voltage for them and they are NOT on the same circuit as the mill. the mill has a dedicated breaker for it, no other load on that line. as of installing the new comp....when the mill starts a job and ends up forcing the compressor to kick on, it shoots an error to the mill and stops the job. real pain in the backside. solution for now....shut off the air while small mill jobs are completed. otherwise each time the comp turns on it forces us to start the job over. additionally, if i pause a mill job and turn on the compressor it does not error while in standby. but as soon as i resume the job, it errors out.
