I replaced my pentium XP machine (it was being a flakey pain in the butt) and I bought a refurb ThinkCentre and installed Win7 32bit.
On my old machine I had a VistaCNC second parallel port based on the MosChipMCS9805CV. This was used for the Vista CNC iMach III Pro pendant. It was working just fine on the old XP machine without any issues.
One the new machine, the port addresses for the 2nd card start with 2030 and 2028.
On the new machine, each time I boot up Mach3 diagnostics shows the second port as all LEDs on. If I set the address to 2028, save it, then set the address back to the proper 2030, it will sometimes make it work. Or it might just be the first 4 LEDs stuck on. Once it decides to work, then it will be fine until power off.
So here is what I have done:
- latest version of Mach3
- Mach Vista registry update
- checked BIOS - no switch for a second parallel port, only for the primary built in one
- device manager - legacy is checked off
- installed the latest 32 bit MosChip drivers
- reseated the card and the pendant plug
- the second port addresses do *not* change each time on boot up
I have read though a number of parallel port threads and found similar problems to mine, but no solution. Any suggestions
I know I can get a USB pendant, but I have spent way too much on this new CNC, so really want to re-use what I have and not buy a new pendant.
Suggestions?
