So I’ve been having a bad time with my TAZ 5 which I bought last year - My prints have been looking horrible due to ineffective part cooling which I have tried to rectify but haven’t had success. My solution was then to double up the fans but I only had 12V fans and a little buck converter but, like a fool, I installed the converter backwards and then when I turned the fan on, everything shut down.
I am still getting 24V in at the blue connector that comes out of the power supply but the LCD isn’t coming on and if I move the bed, it doesn’t flash either. I’ve opened the electronics control box and the big blue 15A fuse is still fine and nothing smells of smoke but no LEDs on the board go on. Have I fried my RAMBo?
