MH871 Motherboard bad??????? HELP!

[bigtracy 4]

I need some help and I am ready to call tech support. I think maybe my Motherboard or I/O board is bad but I want t know which one before I have one overnighted to me. So I thought I would post on here first to see if anyone had the same issue?

I am running XP on my PC using Flxistarter (Roland PNC-1000 driver) and USB cable connection. Have been fine for 2 years and now I get "cannot open port" in production manager and no matter what USB port I use, my device manager does not recognize the cutter when I plug it up.

All functions work fine on the cutter itself and even a test cut is successful. Then, I took the USB cable and hooked it up to my small backup cutter and it works fine so I know the cable is good.

Then, the last time, I plugged the USB into my PC and then as soon as the cable made the slightest contact with the cutter port, the power on the cutter dropped (like it was being drained) and even the fan spun slower and the display went dimmer than normal ; and the USB cable started getting HOT!!!

Next, I decided to ground the cutter to the stand and YES, I should have done this a long time ago but I was not having issues. After I ran a ground wire from the cutter to the stand, the power drain problem went away, but my PC still does not recognize the cutter.

After all that, I went to Staples and got a USB to Serial Adapter and hooked it up via the serial port. The USB to serial adapter shows up in the device manager and after matching the Com ports in Flexi, I tried to cut ; machine never moved but it went through the percentage on the production manager screen until 100%, but the cutter never moved.

Does this sound like the I/O board or the Motherboard??

I am behind on orders and need to have one or the other overnighted to me but I want to make sure that I get the right ting to fix this.

Thanks!

just a thought mine does that but it is new and i have it installed on a network and find that the cutter is paused and stacking up jobs to cut then when it gets switched over i have a ton of stuff cutting. look there first see if it is paused in the printer fax section. hope you get it fixed

Thanks for the idea. I had tech support on the phone yesterday and they think it is my I/O board. I am having one sent to me and will post the results. Hope it works!!!!

New I/O board should fix the issue, and they are pretty simple to replace.

Well, the new I/O board did the trick!! Thank goodness I am back up and running again!! Tech support was very helpful and professional!
