Laser CNC, board MPC6515 driver panel PAD03 V1.2. In PAD03 V1.2 quartz resonator is broken. question - to what frequency was it. I try 12MHz but not succes.

Re: Laser CNC

if you know the part number on the microcontroller then you can look up the crystal it probably uses
so lift the sticker and see whats under it

Re: Laser CNC

It might be a mpc89e58, similar to a 8051, it should use a 12mHz crystal, Did you try an actual crystal or a ceramic resonator?

I try 12MHz but not communication with MPC6515





I will try another frequencies. I'm using now an 8MHz quartz resonator now, it shows the same message, but currently I don't have a communication checking machine. I will check on popular frequencies while in the company.

Re: Laser CNC

Check and see if it has a low voltage detection ic chip because some micro controller use this type of device and it will cause it to keep trying to restart in a loop

It would be located on the 5 volt rail near the micro controller input pin the device is normally a 3 pin device look at the data sheet for what would a low voltage detection circuit
