I know that Dwell in milliseconds hadn't worked with the smoothstepper in some time. I'm not sure it ever got fixed.
My question is, if Mach & Smooth stepper only supports Dwell in Seconds, then will fractions of a second not work?
G4 P0.5 This seems to be totally ignored and 1 second is way too long.
I'm doing tapping routines and I'm trying to fine tune the Dwell between the M4 and backing out of the hole. Anyone know a way around this?
(Mach 3.43.53)
Thanks,

Richard,
Must be a recent bug addition. When I used a SmoothStepper, fractional delay values worked fine. Try an older version of the plug-in (I think I last used v05ogx), and I think you'll find it works as it should. I don't understand why the millisecond mode has never been fixed....
Regards,
Ray L.

I hadn't had any luck with any dwells set less than 1 second. I also noticed, when running on PP port, my spindle stops immediately at the end of the feed down depth and with the smoothstepper there is a delay so my tap extends much more than normal. I guess this is due to the usb delays or the way the SS works. I know my VFD stops on a dime and reverses quickly, but when running G-Code it seems there is a delay between machine motion and the spindle.
Maybe I can put a slight underfeed in my Feed coming back up so the tapholder isn't stretched out so far when it comes out of the hole.

As far as I am aware the SS has never taken notice of the Dwell setting in General config and will always treat a dwell as seconds. I had thought I had remembered an option in the plugin for setting this but I just looked and dont see it so I must have been mistaken.
