GRBL Commands not working as intended?

Good day,

I have a Lead 1515 with a blackbox x32. The problem I have at the moment is that when I run my programs, the (Router11 is connected to an IOT relay) doesn't start spinning until it has moved from zero to the initial cut point, at which time it hasn't reached it's full cutting speed and ends up breaking the bit as it drags across the work surface. I have adjusted the post-p (G4 P1.8) listed below to P5 yet all that it does is pause moving until however many seconds entered has elapsed and still doesn't start the spindle/router with the M3 command until after it has moved to the initial cut point.

G0X0.0000Y0.0000
M3S10000
G4 P1.8
G0X0.0000Y28.9375Z0.2000


I can only assume that my understanding of how the Gcode is read is flawed as I would think that the controller would read each line in a downward order.

I would greatly appreciate assistance from the community in understanding how to start the router then wait x seconds before the gantry begins moving to the initial cutting position or move to the position, start the router and pause x seconds before beginning the cutting process.


Thank you for your assistance in this matter

 

Yes that actually was the issue, seems like it's usually the little things that cause the most issues sometimes.... thank you
