I am having a similar problem with a 6mb on my Mori-Seiki. I can download to the pc but suddenly cannot upload to the machine,boom error 86 . We have changed to a different pc, swapped out cable and replaced the i/o Punch board. The service tech hooked a break out box to the rs 232 port and determined it to be in the machine. Now they (service tech) want to pull the entire motherboard and send it in for repair. I drew the line there.
There has got to be a way to check things out and not have to tear the machine apart to fix it. Any ideas? |
