Just curious...
Can you make the UP arrow key, move the crosshair Up the screen with the Y axis DRO going NEGATIVE as it is moving ?
Or is that locked internally ?

Nope, Y+ is always up the screen.

Nope, you can have any key you wish for the Y+ or Y- ,  but Y+ will always move up the screen so you will need to make an upside down screenset and turn the monitor upside down, problem then would be X goes the wrong way ;D

IF in CAM you set the 0,0 to the top left then everything will work fine. When the program posts it will set the 0,0 to be top left. That is exactly where you need it to be when you set 0,0 to the left of the stationary side(back jaw ) of the vise.


Hope that helps

Not necessarily, in some CAM packages if you select the top left corner as the origin it will then rotate the part to suit normal convention, thus the need to define the X, Y and Z directions.

 It does work as you guys say in SheetCam, don't see exactly how to differentiate the part origin from the machine origin though. Need to work on that with a bit of study.
Will try with another CAM when I get a chance.
Thanks.

Hood, I have Never seen that.  In all the Cams I have used IF I define the 0,0 as top left the Cam will Draw and Post it that way. Now IF you do not define it it will ASSUME the 0,0 as bottum left and Draw/Post it as such.
