Hi I'm a bit of a newbie but have a simple question.
I built a CNC Machine but I am using it for painting. I use the M3 code to turn on my paint sprayer. My problem is once I turn on the sprayer I want it to move right away and it doesn't. It hesitates for about 1.5 seconds and I get runs with my paint. What can I do to get it to turn on the spray and immediately activate the x-axis movement? I initially had the M3 code on it's own line then added it to the G-code line but that didn't really speed it up like I thought it might.
Any suggestions would be helpful.
Thanks in advance.

In Config. / Ports and Pins / Spindle Setup - set the spin up & spin down delays to zero.
If that is still not quick enough then try the M10 / M11 commands which will turn ON and OFF at the instant of movement. I have described them in a bit more detail here :

Yes, I checked my ports and pins in spindle setup and yes there was a 1 second delay so I set to zero. I haven't tried it yet but I'm sure that will make a big improvement. Thanks!
