Re: MY 210 GECKO BURNED!!!!!!

Ok,
My power supply has 4a fuse in its positive output (secondary) and
this wire goes to 3 fuses (5a each) connected to each driver. there
is on driver that do not allow the whole system to power on. the fuse
that goes after tranformer blows up but if just two drivers are
connected it works fine. One thing I noticed today is when the whole
system is power off the stepper connected to the damaged driver does
not rotated freely like the others two. somethingmust be in short.
Any suggestios??

Luis..
