I was working on a CNC with a brand new AXBBE Controller. Everything worked perfect for 2 weeks. But slowly UCCNC started loosing connection for no particular reason sometimes. Usually it was solved by rebooting the PC (windows @##^ù^m!!!)
Today i was working on the machine and it happened again but this time impossible to reconnect. As i went to check the control box i noticed " power failure " was activated. So i guess it has to do with the 5V power supply.
I am using meanwell DIN rail power supply 5V 2.4A as suggested for the AXBBE. Voltage was at 5.15V instead of 5V, but all is stable.
I haven't been able to reset the AXBBE properly. Looking at the documentation i read " To remove this fault condition the 5V power connected to the board has to be toggled ". Does it only mean " turn off " ? Maybe there is more to what i understood.
I also check wires around the box and it does not appear to have any short circuit.
Here are my questions :
- How can i properly remove the " power failure " condition
- Is it possible that the controller is faulty/damaged ?
- If voltage was a little bit more than 5V ((5.15) is it bad ?
- Maybe the board was defective ?
Haven't had any issues with AXBBE for the past 3 years, i love the boards and that they were conceived in Europe
.I have some in stock so it's ok i can deal with the replacement.
Just trying to understand what could be happening
Thank you for your help !
