I have a videojet 3320 co2 galvo laser engraver.
The machine power on fine the white led(in the controller box) flashes and after 1-2 mins stop flashing and is constantly on.
After that i turn they key switch(in the controller box) the red led(in the controller box) lights the laser tube power on for 2 sec and after 2 sec laser tube power off the red stop lighting
and the yellow led(in controller box) flashes..
The yellow flashing led as the manual says it is some alarm that some problem exists.
Controller has a pendant to simplified control that connect to controller with ethernet.
Pendant powers on but seem to have no connection with controller because is says waiting for laser and when i remove the ethernet plus it says the same.
Also with pc i can not connect with smartgraph software.
I have set the dip switch 1 to videojet 3320 in on position so videojet has 192.168.1.1 ip and i have my computer to have 192.168.1.15 ip.
If i remove the 256MB mmc card when powering on the with red flashing and does not stop flashing after 1-2 minutes(with mmc inside card stops flashing after 1-2 mins).
I got the machine used and it worked previously with a siemens plc with some sensors, the plc connect to videojet via serial port of videojet.
I don't know if the machine is faulty of needs some input from plc to start..
Any suggestions what can i do ?
If controller is not repairable is there any general controller for galvos to change it?
To debug it i have the following tools
solder iron/hot air/bga reballing station/multimeters/oscilloscope/esr meter(for caps)/transistor tester/flash-eeprom programmer/bench power supply
