General Mach Discussion / Re: mach3 homing direction
« on: September 28, 2007, 08:15:24 PM »
tried the suggestions from my previous questions - thanks for response. Still confused as to directions. Understand z/x/y +ve's BUT where does Home go - mine seems
to go zero all three and then to move OFF Home I have to neg on x/y. Z is o.k bcos -ve down to work.  So, is Home max x/y positions and then I have to offset work
to ive max's to get zero/zero THEN everything is positive?  Sorry to be slooow on this

Yes this does help - thanks. I have a limit switch on each axis which I have also config to Home switch. When Home ref everything goes to limit switch as expected.
To move off Home I have to use "G0 X-1" for example, should that be "G0 X+1" am I reversed?

thanks for suggestion - I will try today. In general then, once in Home position, to move an axis it is a negative number "G0 X-1" for example. Or should it be positive,
does this mean my motor is reversed direction?

just completed 3-axis mill machine, using xylotex drives - all working o.k using limit/home switches (3 inputs only) on all axis. When using ref home command
all goes to home as per expected - upper left. When moving off axis I have to put "G0 X-1" etc (nagative numbers). O.K with that if I go 'G0 X-10 Y-10" and then
use work offset set to -10 -10 I can then use 'G0 X+1'. When using WRITE plugin the text is reversed (well as if routied on underside of board) even though
screen shows text in correct format/direction as job is run - confused as to what is going on?  Sorry if I am redundant question.   :-\ thanks
