Power supply issue
Posted: August 12th, 2016, 12:03 pm
Hi everyone,
I built a HICTOP i3 Prusa model 3DP-17 with auto bed levelling and filament monitor and put everything together. The control board and LCD work fine when plugged into USB, but the power supply only works if I disconnect the power supply from the control board. As soon as I connect the control board, the power supply LED shuts off and fan stops. There is no motor or heater activity at all.
I used a multimeter on the power supply. I get 115V at the cable from the wall, and at each connector, I get 23.9 V DC. I have double checked the polarity and it is correct. Any ideas?
Thanks
Mike Poling
