Troubleshooting non responsive machine- Mach3/Syil x4

[paulus.v]

I’m abit lost sorry - I thought the bob was the issue? The machine has worked, I’ve used it for about a year- the problem came after moving it.

Would I be correct to say I need a new bob and motor drivers?

No. Unless you really want/need to make an upgrade. I doubt you have fried your motor drivers.

Could you start again troubleshooting the signal, starting from your computer?

First measure the parallel port pin output voltages to see if mach3 outputs signal when you send commands and if this signal is 0-5 volt. If not, there's a problem on the computer side. It could be mach3 parallel port driver, computer power management, bios settings.

If mach3 is transmitting and receiving 5v signal through the parallel port then most probably the BoB is the problem.

If you need more detailed assistance in checking the signal I can try to give you a step by step guidance.

Checked and mach3 is sending 5v through the parallel port
