I got this stepper driver to be used with this motor. https://www.sparkfun.com/products/10847
I successfully used it with a low voltage supply but read that it would have superior performance if I used a higher voltage. Keep in mind that even with this low voltage the driver got very hot.
I then switched to 24V power supply and as soon as I turned it on the driver immediately went up in smoke and a section of the transistor array seems to have melted from the inside as small lumps are now clearly visible. The interesting thing is that it wasn’t hot to the touch even though it was clearly burnt out.
I decided to purchase the big easy stepper driver but I don’t know whether to expect the same thing as both include the 24V supply within their rated voltage inputs.
No public wish lists :(
