i have a sculpfun s9 the mother board needed replaced. after replacing it now will not turn on laser and keeps connecting and disconnecting. if i try to frame it does nothing and the fire button does nothing. when i do start it tell me the laser is not recieving anything from the computer. i replaced the usb cord and still nothing. what is the problem?
If it keeps connecting and disconnecting, the power supply might be the issue. Do you have any video? Did you make sure all wires are correctly connected? Maybe disconnect all of them and then test if you can establish a connection with the PC.
