Steve,
The file below has my Mach4 Input and Output Signal setting for HiCON.
These work just fine for example Mach4 V3804 the spindle starts just fine.
I have used the same settings on many Mach4 Programs for many years and have machined many carvings all without issue.
But now it will not start.
Regards,
Mauri.
