The doors of both the arduino as in the CW are set on COM5, but the leds of the arduino does not light up when a signal is sent by the CW.
as a parent, is correct, because the engines in another progarma function normally.

Believe that the driver of stepper motor are not the problem, because they usually funcinam with another program.

I hope you have patience with our language, because here is from Brazil and our English is not so good.

if you are 100% that you do not recieve "ok" when using the arduino terminal
the problem is your arduino code is not uploaded or running correctly.
this needs to be correct before you can move on to CW .

check you are uploading the arduinocode correctly to the correct comport & board settings

I'll check, and you return.

ok so the program is working

have you adjusted the steps to match your machine configuration in the arduino code ? as instructed (PlatenStepsPerLayer)
and set the switches on your stepper driver to match ( 16 microsteps)

see this section in the arduino code:
> adjust "PlatenStepsPerLayer" to adjust the layer thickness. for example, for a 0.1mm layer thickness using a 10 mm pitch lead screw driven
> by a 200 step per revolution step motor running at 16 micosteps per step (3200 steps per revolution) you need to set PlatenStepsPerLayer to 32.

what ballscrew or threaded rod are you using for your z axis ? ,
you will need to know the pitch to correctly set the above . i.e how many steps per mm of movement then divide by 10
i.e using 0.9 stepper motors (400 steps per rev) with a desired distance 0.1 using M10 Threaded rod ( 1.25mm pitch ) 0.1mm = 32 steps
but using standard 1.8 steppers (200 steps per rev ) this becomes 16 steps

your DIV168 will need setting to 16 if you have not already done so (sw1=off sw2=on)

attach your test gcode
