General Mach Discussion / Still stymied by my LPTs
« on: January 13, 2011, 02:35:00 PM »
I had been using my Mach3, WINXP, Zylotex, Sherline 5400 mill setup for some time when, just after Christmas, I started having harddrive problems. I've switched to another HD, but can't get the setup working again, apparently because of LPT problems. I recall I had problems there initially, too.
I'm using a Rosewill PCI board with 2 additional PPs.
Checking Device Manager, I see LPT3 as being at 0xDD00, and set Mach3 Port1 equal to that value (enabled). Incidentally, when I change the port address in Ports and Pins, I have to force the Apply button to become active. Subsequent checking confirms the new address.
Motor Outputs are enabled for X, Y and Z. With the cable connected, I get DRO values to change, but no motor movement.
Checking with a multimeter, I see unchanging +4.90v on pins 2 through 7, which are the assigned Dir and Step pins.
I've run DriverTest, and get Excelllent results.
What else shall I try?
