Buildbotics controller not powering up

Hey ksw,

you could try to see with a multimeter if the Meanwell power supply has its AC input power. If so, you could check if the power supply delivers 36 V DC power.

If it has, you could short J18 on the AVR mainboard, the controller should boot then. If so, the pushbutton is broken.

wood dust on the pcb or overheating can make this. The solution would be sufficient dust extraction, enclosing the controller in an enclosure with a big fan and a HEPA filter , and replacing the noisy small fan by a 120 mm fan in the top of the case. If the system freezes it is certainly the smaller upper pcb which is the Raspberry Pi. I don’t think it is much ventilated should the environment be hot.

Should wood dust be the cause, I would use a ESD-safe brush to try to clean the pcb. Or you remove the pcbs and use CRC KONTAKT LS to clean them.

Also if you had a problem with the SD card, I would not overwrite the old one but buy one of good quality (Sandisk brand).
