Computer swap - need help
« on: April 07, 2017, 10:23:30 AM »
Hi guys.  I'm new here and looking for some help that is hopefully it is a small issue.
I have an older plasma table that uses candc drives and serial and parallel ports .
The original computer gave the blue screen of death.
So I replaced the computer and i have one small problem.  The torch on relay keeps flickering,  it will actually turn plasma on if the power is on..
The motion is working fine.  I tried the serial port test button in mach 3 and it says that there is no serial communication.
I have checked the addresses and it appears ok.  Windows says the port is working.
Any help would be great, I've been staring at it for a day, rereading the same stuff, and I think I missing something.
