General Mach Discussion / Problem with pp port ?
« on: September 22, 2008, 01:47:40 PM »
Hello all,
The problem i have is getting mach to output 0-5volts on pin14 to control the anolog speed control which is 0-10v.
In ports & pins /spindle :-step pin 14, dir 8, port 1,
In motor tuning/spindle :-steps per 1000 , velocity 1500, pulse 3.
Spindle pullys:-Max speed set 1220 ,ratio 1:1
With the command m3s1220 the voltage on pin 14 changes from .08volts to .25volts. however if pin14 is setup as dir pin
on either z or x the voltage swings from .08v to 4.4v .
tried deleteing the xml,s and re-installing mach, but still no joy .
help please,
rgds mick.
