Thanks for everybody it's wonderful we can help each other around the world !
Chip, i tried to select the Sherline 1/2 Pulse Mode - not help , i tried setting the LowActives "Step & Dir." States to "Checked"- not help and i see the Pulse Frequency & Time in Int. values on the Diagnostic Screen.
i attached the files help i got from the supplier (thanks for the photos you send , you know one photo alike 1000 words )
Hood, you said to run the driver test, i run it before and everything was like the video toturial (32-36 Time between pulses Us), but now i checked it when the Mach3 was opened and he gave me 18-64 pulses sometimes . second when the test opened and "system test in 3..2..1.."
i got a message in the target windows "pulssing too fast" .
mabye this is the problem ! what are you advice me to do ?
