Thank's Mark Εισαι Φίλος και με καταλαβαίνεις !Oh sgive me a break with the dumb suggestions pleaseee.. it was working ok with his portable and the Asian card.. Now you go back 15 steps. He pluged it in and it smoked the TB6560 CHIP. What more do you need. He ran it on 12V and it smoked the chip.
Do you even have the MK4 with MM160 ? Are you even using it to make items or just spinning motors on a table.
I have the MK4c and 4x MM160. It works fine once you sort all the bad information provided by Soc Robotics in the Ebay auction and spend time exchanging Emails with Stephen. Mine did smoke but I cought it in time. It has to do with the enable pins and the TB6560 chip. You can go read the other threads regarding the TB6560 driver chip.
