Hi,

I want increase the step pulse to 60us. I tried to activate "Sherline mode" but the maximum step pulse is 40us. Could you give me the different step for increase the step pulse please.

Thank you

I don't believe that you can.

Hi,
I think Ger is right, you cannot program Mach to produce a 60us pulse.

You could make a circuit to do so if you wish. It would require one IC timer per channel, probably a simple 555 timer for cents each.

Do you mind me asking why its necessary to have such a long pulse? Do you require similarly extended pulses on other channels/axes?

It's work!! I have used NE555 timer. The datasheet of "CharlyRobot" said me that I have need a long pulse. I use a rack of CharlyRobot. I keep the power party and I have replaced the command party. Like this -> http://www.usinages.com/threads/un-nouveau-avec-une-charlyrobot-emc2-sous-linux.24645/

Thank you

Hi,
they look like ordinary steppers to me. I think I would try a regular stepper driver, probably a Geko and see if it works, I suspect it will.
Thereafter conversion to Mach is straightforward.
