I have a driver board I got from ebay, and it worked for a little while. It uses TB6560 driver chips. **broken link removed**. It's 24V.
I know the Y axis driver chip blew out, I may have connected a motor wrong and damaged it while I was learning. First it wasn't driving the motor well, the others spun smoothly but any attached to that just vibrated, then it made a sizzle and pop sound and the power supply shut itself off. I found inky black stuff that smells like ammonia on the pins of the chip. If I connect it to power again it shuts off every time. I checked the power supply and it's ok.
I don't know how to check the two regulators, there is a 12V and a 5V regulator. Is it likely that just the driver chip being blown would make the power supply shut off? The regulator chips are so cheap I'm tempted to just replace them just in case. I would hate to put in a new $5 driver chip just to fry it again because something else is bad.
Would it be a good idea to remove that chip from the board and try powering it up? It seems to me that it would not damage the board to have one of the driver chips missing and if that is the only bad component it should power up once that is removed.
Any advice would be appreciated on how to go about checking the components and what I should look for based on the fact that I know the driver chip blew up and that the power supply shuts off when connected to the board
Thanks
