I have noticed different behavior with the 4.5 plugin and my DMC1425 versus the 4.4 plugin with my PCI DMC1800.
When I trip an limit or E-stop button with 4.4 and my DMC1800, mach 3 goes into E-stop mode instantly, and the machine stops instantly.
When I trip a limit or E-stop with the 4.5 special plugin and my DMC1425, mach3 goes into E-stop mode instantly, but the machine will keep executing commands for a bit (maybe a second?) before it notices the E-stop.
Also, if I am holding down an arrow key to jog the machine, and trip a limit, mach3 will go into E-stop mode instantly, but the machine will keep jogging until I let go of the button. Once I let go of the button, the machine will stop completely and remain in E-stop mode until reset.
It's almost like the plugin doesn't notice that Mach3 has entered E-stop mode.
Ideas?
