I have a "Tangent Blade"/scroll saw/contour saw 3 axis machine I have been tasked with fixing. It is controlled by a 2011 Dell Inspiron PC, with an Intel Celeron CPU, on a windows 7 32-bit operating system, running Camsoft CNC software.

The issue is the computer crashes frequently sometimes while idle, sometimes in the middle of a running program. My best guess is the CPU is the problem because when running the software, the CPU is at 100% use (according to Task Manager), although the machine and computer have run for years without much issue until recently.

I have cleaned out the computer of dust, I upgraded the ram (there was room), I have deleted all software other than the bare essentials and the Camsoft software. I have disabled anything unnecessary from running in the background. None of these solutions have worked.

I thought maybe a more powerful CPU could work, I grabbed a Windows 7 PC with an I5 CPU, Put the GALIL Chip in it, Put the Hard Drive from the other computer into it. Plugged in the two access USB's. With this new arrangement I have no crashing and the software runs however now the Saw does not seem to be receiving any communication from the computer. The specific error code I get is "Galil Error:-2 22 Begin not possible due to limit switch". Essentially meaning the software thinks the limit switch has been triggered which is not the case.

Anyone know why this would be the case?
