hi everybody this is my first go and its a problem
i have the deadly series 1 with a boss 6 control and it has stoped driving in x axis the stepper motor tries so i have replaced the faulty diodes which then it seems to blow 5 diodes later im out of ideas

I had a lot of problems with blowing transistors when I first got my boss 6 mill. Make sure you have leads hooked up correctly. Also you can move another axis board into a non working axis. Listen closely when you get new transistors in power supply and see if you can hear speed of motor slowing down before motor stops as motor is supposed to ramp down speed before motor stops. Otherwise you will get transistors shorting. I had a circuit board messed up when I first got my boss 6. Do you have an X-Y-Z check list? If not I can scan mine and email you a copy if I had your email address. kw grigsby
