Hi,when I first set up my machine and greener,I was doing 'motor tuning' with the help of someone walking me through the 'unknown' over the phone.For 'maximum pulse width' I used some form of text editor to change the number(when I just change the number in the 'motor tuning' window,it does not 'save').Can anyone tell me how to do this edit?
Also I recall him commenting that  we had to increase the pulse (14usecs) and he was suprised how high we needed to go although he didn't start any lower than 10 usecs ; now this is a small desktop Sherline using their driver,so I suppose the minimum required pulse, as applies to more expensive setups must be from a cost standpoint, more negotiable.But as I read the Sherline literature they say the minimum pulse is 22usec!?Comments?-Thanks,Keith

Hi Keith:

  If your using a sherline, ignore the pulse width, just select "sherline mode" in the ports & pins, it will make all the pulses 40us..

Thanks Art.I must not have that option in the 5.6 of Mach2.Note to self: update-Keith
