Dwell Issue with Spindle

General
1

Hello,

I am having a strange issue with my new install in that despite setting the dwell (M3) straight after my S3 command the spindle does not begin spinning up until after the dwell.

The spindle is also turning off during rapid moves and then back on for the next plunge.

I have attached an example of one of my Gcode files where this is happening. I am operating on a Lead 1515 machine, PP is on Vectric.

My concern is that it will break bits and damage work if not fixed.
Any idea what is happening here?

Thanks

That is your dwell command which is 5 milliseconds long. Maybe change it to 6000

Does your controller use grbl because i suspect the laser enable is on, as annotated with $32=1? You’ll need to change $32=0

Yes indeed that worked. BTW, 5 seems to be seconds rather than milliseconds.

Thanks for your help.

I’ve heard g4 is up to controller interpretation. Glad it’s figured out though
