My designated computer that runs windows7 updated yesterday morning at 3am. and when I was leaving for work I noticed a light that is normally off was lit up but dim. (the light is feedback for the power supply that runs my drivers and breakout board in an empty computer tower I built) Now the updated computer seems to be sending power back through the installed printer port cable into the c10 board in the empty computer tower and energizing the c10 breakout board. When I open mach3 my dro's move but my motors don't, also my air solenoid relay is on all the time as well. The power light on the c10 breakout board is dim when switch is turned off and lights up full when I energize the power switch. Im not sure what could have happened, maybe printer port went bad? I was using the machine Monday night. any recommendations please...thanks in advance
