I have a problem getting the pendant to work. It seems to be conflicting with my 485USB that controls my spindle. I can see the port that the USB485 for the spindle is but the iMach3 pendant doesn't show a port number. I've looked in the device manager and there is no port that is showing up for the iMach3 pendant and when you go into Mach3 to configure it there is no place to assign it a port#. I gave the 458 a different port number and I can get it to work thinking the pendant was trying to use that port# by default but when I plug the pendant back in I get the same problem that the VFD can't see the port anymore. You cancel when it ask you to edit it because it says the port is open and you have to restart Mach3 with the pendant unplugged. I have tied to contact VistaCNC for about 2 weeks with no response. Is there any reason why this is happening?
