Hi,
I have a High-Z S-720/T from cnc-step with Zero 3 5ch Controller.
It work fine with Windows 10 and the USB Box.

Now I want to let ist run under linuxcnc with the onboard parallel port.
But I hear only some noises from the Motors but it doesn't move any axes.

Have anyone a working configuration for me?

I try in the mainboard BIOS ECP and bidirectional.

Thank you for Help
Chris...

Did you simply import the Mach3 config into Stepconf or start from scratch?

At least noises is _something_. At a guess your step times are too short, or the step polarity needs to be changed.

Well, try longer step times (5000nS normally works) and if that is no help try inverting the polarity of the step pulses in stepconf.
