OK as per my previous thread, I'm concluding that my desktop's on-board parallel port simply isn't working right and probably never will. It could move the axes around basically but kept stalling out immediately at much lower speeds than it could keyboard-jog at when running code or a move command is manually entered. Every software fix has been tried and nothing had any effect.
So I went to Goodwill and picked up a Siig CyberParallel PCI card to try. The system recognizes it and says I have the latest driver.
I went into BIOS and disabled the on-board parallel port.
I set the Siig card to LPT2, IRQ 5. I could not find any setting for port address (the 0x278 thing). So I'm assuming (hoping) it uses what is "normal".
No response from Mach3 with it configured for LPT2. Mach3 says it's online and moving, the controller hardware does nothing at all. No motion or sound or anything.
I changed the Siig to LPT1 and reconfigured Mach3 accordingly. No response.
I removed the Mach3 parallel port driver, rebooted, reinstalled the driver, and rebooted (exactly as per the Installation Guide). Still nothing. Changed to LPT2 again. Nothing.
DrvTest.exe saw no problem and declared the system "excellent".
I did try removing the card and reenabling the on-board parallel port in BIOS. It didn't seem to work, no response from the controller. I tinkered with it awhile but put the card back in and went back to trying to make the card work since I know the on-board parallel isn't going to really work anyways.
Any suggestions on getting this card to work? Are there any known issues with this card?
