just driving me nuts that everything has been fine for years, and all the sudden its going crazy

thanks for all the suggestions, i'll try some of them out,,, i never thought a keyspan would help since its direct com... straight analogue should be more reliable... but you never know,...

I guess i celebrated prematurely, it did it again on me... i dont think its static now because i even built a strap from bare wire that runs across the vinyl, and i wiped it down with a dryer sheet, i just dont know now.... i could just cut smaller designs, i just would rather have it working properly

I think i figured it out, i was reading a bunch of threads about this issue and finally came across one that explained that the point of the ground strap was to remove the static from the vinyl via the rollers, and suggested checking continuity from the ground strap to the rollers... surprise surprise, i had none... so i rigged up a ground strap for the roller, i just loosely tied the wire around the roller and then braided the wire... since its loose it doesn't inhibit the roller movement, but it does create the grounding needed, i re-cut the same design again and it worked fine. thanks for everybody who contributes on these boards, couldn't have fixed it without the suggestions here.

Hey all, I have owned my MH871 for years, probably 7ish years, its worked flawlessly with signblazer up until this point. I reconfigured my desk recently and now since then my cutter will do about 20(wide)x8inches worth of cutting and then just go completely rogue cutting in random directions, then continue the project some way down the page. To the best of my knowledge no settings within signblazer or my device manager port settings were changed in any way. Oh and also, yes, i do have a grounding strap from the cutter to the stand, and i am using a grounded outlet. I took my machine apart and cleaned it out, made sure all of the connections were seated properly, i checked my com port on my computer (com'd direct from my mobo header to the machine, no USB) the only abnormality i have noticed is that signblazer all of the sudden sends to the cutter a LOT faster, previously signblazer would take about half as long as the actual cut just for the sending dialogue to go away, but recently it sends in just a few seconds... i think perhaps this is filling the buffer/memory on the cutter and it gets lost... i have cut the same design several times right on top of each other to look for inconsistencies and it seems to go rogue at slightly different points. any suggestions would be wonderful.
