I am using a Master Plotter XY300P.In the past I used the program that came with the plotter, I think it was PCSign. Then I purchased SignGo FD, because PC Sign wouldn't work with the anything after windows vista. I rarely used the plotter and didn't have too many issues. Now we started to use it with Windows 7.
Now, when we cut often it cuts fine, Then all of a sudden the head will just cut a line across the vinyl. Or sometimes, the head won't lift up upon returning home and cut a line through everything on its return home. Then other times the head will just run straight across and slam the plotter (cutting the vinyl) and bang against the far wall. At first I thought this was due to a serial to USB adapter for my serial cable, so I installed a serial card and seem to still be having similar problems. I am going nuts, now that we are starting tpo get a couple of jobs using a plotter again. We are not getting so many as to really warrant going out and buying a new plotter yet (however we hope this happens soon so that we can buy a new plotter). Any help would be GREATLY appreciated.
Here is an example. (Red line is the messup)
The first one is what the plotter was doing before. after cutting the box it wouldn't lift and cut through the rest of the vinyl.
The second is what I am getting today. checked all connections and settings. The red line starts at the a and continues. I stopped the cut at this point, that is why there it ends where it does.
For better understanding, here are all the setup files for both the serial port and SignGo:
