Hi,
I attempted to solder my Stepper wire to marginally thicker wire (.3 mm thicker) and blew out one of the polarshield stepper shields in the process. I am not sure why this happened as it was 300v wire. This also happened with my adafruit motorshield.
I have now purchased awg 24 wire which is slightly thinner than the stuff I previously used in my extension attempt, but I am worried that I will burn out the shield once again. Any thoughts as to why this is happening or solutions would be greatly helpful.
Yes, I have had everything unplugged during the process and am using polargraphSD power supply and parts.
Thanks,
Erik
