I just reset my terminal... and for some reason JOG and everything is now in reverse.
All values of movement are negative and are outside red bounding box, same goes for physical movement of my mill that is any movement will put me on hard stops and to go the other direction emc2 says JOINT area out of bounds!!!!!!!!!!!!!!
damn it what setting would be kept in memory and then reverse on a reset?
tried changing same and opposite settings in stepconf with no change, reversing table settings + - and even using the original *.INI after all that is everything I have changed and yet here I am stuck in the land of mirrors cnc style.
any ideas what the hell is going on?

If you left an offset that could explain why your box has shifted.
Jogging all axes in both directions makes them go the wrong direction now?

I can see nothing obvious that would change the directions of the motors.
Unless something changed in the HAL file.

You might look here...
wiki.linuxcnc.org/cgi-bin/wiki.pl?Coordi...t_what_should_you_do
and
wiki.linuxcnc.org/cgi-bin/wiki.pl?CoordinateSystems
As to the first question...
If I understand you what you are looking to do is set the coordinates for your work piece, just as John stated.
So in that case home your machine then jog to the start position of your work and "touch off" your x y z axis there.
All your g code will consider that location to be x0y0z0 as will your screen.
You could then jog to a new location and touch off there.
If your machine home position was originally x0 y0 before you touched off
G53 G0 X0Y0 will still bring you back to that original location.

I havent placed any offsets that i know of..... where would i look? how would i remove them? bigjohn?
thanks for the INI feedback guys ! i had a feeling that is wasnt something i had done in there.
To give you some idea i am stuck in the top left hand corner of my milling table. I can phsyically move 2.5inch x,y in that corner with ALL IN NEGITIVE values before software stop is applied (red bounding box); if i go the other direction i hit my limit switches with POSITIVE values and is outside the red bounding box. this should be the other way around!!
for instance if i change the INI table values to exact middle of my table on all of my axes, the above is still true! only I have room to move before hitting soft limits (red bounding box).
In stepconf same and opposite arent bringing the gantry to the other corners either; for some reason they arent working. other wise it would be a simple solution of going opposite opposite same and using the inverse corner.
nothing comes easy... it was all working fine sunday until i restarted my computer.
if only i could find that setting that flipped for some god unknown reason

Restarting your computer should not have any effect on your configuration.

yep tried the what to do if stuck section. nothing happened.
my movements are still in reverse that is negitive.
im currently trying something in stepconf and i will let you know if it works.
if not im still open to all your suggestions.

ok well i have solved half of the problem.
I have clicked the invert boxes in stepconf pinout and now have all three axis heading in the right direction with the correct values via jog.
HOWEVER
now it seems that same and opposite latch directions seem to do nothing! in the stepconf file latch direction value is (0)
I have changed the stepconf configuration file both in program and manually to (1) and emc2 still does the same thing.
Modal Gcodes have been tired and disabled.
oh and thanks for the wiki links I am ashamed i didnt look there before begging for help here; my humble appoligies. should have known this wouldnt have been in any one of the three manuals.
well atleast i know how to use the gcode offsets and touch offs work now! :-D wasnt a complete waste of time.
now just to get those limit switch latch directions sorted...
just name the files and you will have a print out. im all ears (and seemingly no brains)

ok.... i think i have to rethink some things...
i just found out why latch settings arent working.... they are! they are just that small i didnt notice.
the diagrams in the intergrators manual are determined by the same and opposite settings in step config! not imediately obvious for me.
here i was thinking they determine corner location for homing < ^ >
i gather homing offset does this?
