When I just started Mach4, I get a warning:
"file \Machine.ini, line 2145: key SpindleMax was first found at line 1625"
When I click OK, I get another:
"entry "SpindleMax" appears more than once in Group "/Darwin".
I haven't touched any spindle settings since I installed last night, as I don't have a machine connected. Only 3 motors enabled in Darwin, and the three were assigned to X, Y, and Z in Mach4.
I went into Config:Mach, and saw that the motors were no longer enabled. When trying to enable them, I once again got the dreaded frozen Mach4, requiring yet another 5 minute reboot.
At this point, Mach4 crashes so frequently that it's not any fun even trying to do anything with it, as the crashes ALWAYS require a reboot. Looks like I'll wait a few more weeks and try again.
