No Step pulses on any step axis was created by purwanu

I have installed successfuly the EMC, the latency-test give very nice result on the maximum jitter, it gave around 11000. After StepConf wizard, I noticed there is no pulses coming from the parallel port, the control direction signal is working fine. In my setup, I put all pin into "Unused" except the XYZ Step and Direction.

Have I missed something? I am new to EMC2...

You might try and open the HAL Configuration window from Axis and watch the parallel port pins while you jog each axis real slow to see if EMC is generating the pulses.

Hello,

I tested the xstep pinout, with HALScope, there were pulses. I found that 1K resistor series with the optocoupler was too big. So without that resistor, now the step pulses has driven the L297 nicely..

Thanks...
