Hi, my Lulzbot Taz Workhorse stopped working and I have been trying to fix it and I have run out of ideas of what to try next.
The current state of the 3D printer is: The switch LED is working, the LCD has stopped working and the LED on the Rambo control board has stopped turning on. I have tested the fuses below the plug socker, and the three on the board (the two small 5amp ones and the big 15amp one) all seem to be working, after testing them with my multimeter, I even replaced them to be sure.
Obviously it seems the main board isn’t getting enough power. I’m not sure whether it is because the PSU is faulty or the main board. Does anyone have any advice on what to try next? Is there an easy way to tell if its the PSU or the Rambo board that is faulty?
Thanks in advance,
Threaded
