start to smoke and crack le. I wasn't paying atte ntion late one night
while testing so me boa rds and ended up destroying all the chips
on three boards. Once you are sure everything is OK, turn on the
power su pplies. The first indication that the drivers are wo rking
and that the motors are good is that the motor shaft will be rigid.
It shouldn't be easy to turn the shaft by hand. You will be able to
turn the shaft manually a little, but it should take a bit of effort.
Next, start moving the motors clockwise and counter-clockwise
using the appropriate arrow in the CNC Control window as seen
in Figure 5.\ I.

If all is well, you will be ab le to move all thre~iiijt~ in both
directions. If one of the drivers isn 't working, check-the motor wire
co nnections first to make sure they.are in the correct order. Then
check the thro ugh-holes and traces on the board to verify that all
the co nnections are good. I did have a board that wouldn't work
