Hi Guys, I'm not sure where the problem is, and therefore , which forum to post it in, but here goes.
I recently installed a ESS in my Chinese 6040 Router.
I use Cut2D to generate the G Code and Mach3 to run the machine.

I think this started after the ESS install, but not sure.
Problem:  I load the G Code frorm Cut2D. When I press Cycle Start in Mach 3, the code moves 2 lines ( stops at N140TM06 ) and then stops....I have to press Cycle Start again before the spindle starts and the rest of teh G Code is read.
I ttied the same code in Mach3 in Demo mode on another PC and it doesn't do it!

I assume it has something to do with the Mach 3 configuration on my CNC Machine.( wrong box ticked?)
Has anyone seem this before? Any idea what causes it?

I  have no idea where to start looking. I don't know much about G Code.
I have attached the FIRST PART of the last G Code this happens on, but they all do it.

check your Settings in:

Config -> General Config -> Tool Change

Thanks TPS. You're on the money.
I must have inadverantly selected ' Stop spindle Wait for Cycle Start' instead of ( I assume the default ) 'Ignore Tool Change'

I did look into the M06 Command  and did see ATC mentioned, but I never made the connection.
Thanks again.
Steve
