Hello guys,
I have a problem with spindle speed: I often have programs involving M3 and M4 (both clock and anti-clock turning) but I can't set Mach3 to WAIT until the given speed is reached and, even more important, to wait for the motor to slow down to zero before inverting the sense of turning.
I correctly use the S command and indeed the spindle goes to that speed in the end but it can take a from 3 to 8 seconds depending on the rpm you choose: the faster, the longer it takes.
I know there is a setting in the config page to set how many seconds to wait after the S command before starting machining but this is not enough when you have to wait for the spindle to slow down before changing the sense of rotation.
Since the lathe has an rpm sensor that works perfectly it would make much more sense if it were read by Mach3 to know when to start machining or to wait until TE counter reaches zero before issuing the change sense of rotation.
Can it be done on mach3? What is the command?
Thanks!
