Title: x and y movement confusen
Post by: sivtek on December 17, 2013, 03:04:13 PM

I am confused of the movement on my mill. (Mach 3 settup) I espect the spindle  to go to the left (+ postiv dir.) when I press the left arror, put +10x in the dro and then "go to zero" and put g0x10 in the MDI. The same in the y direction (+ posetiv dir. away from me {or up}).
But this is what is happening in the x dir.:

Press left arrow spindle move to left (OK)
Enter +10 in x DRO, spindle move to left (OK)
Enter g0x10 in MDI, spindle move to right (?)

In the y dir, this is what happen:
Press up arrow spindle move up (OK)
Enter +10 in y DRO, spindle moves down (?)
Enter g0y10 in MDI, spindle moves up (OK)

How can I correct this? My mill is working well, but it is confusing to remember this and its easy to go wrong.

Thanks for any help

Thanks, but that was not the qestion. If you look at my question you se that the movement in one axses is differen according to the way I am using mach 3. I was espekting the spindle to move in the same direction if I used either arrow left, go to sero using dro x 10 or using MDI g0x10. Am I wrong? Have I explaind me OK?
Espect that it is some settings in mach 3 I have missed?

When you enter 10 in the DRO and press goto zero, the tool is moving from 10 to 0. When you do G0 X10, the tool is moving from 0 to 10. Opposite directions.

Thanks, that explains it. The only thing now is to change the direction on the x arrow movement.

I tested the mill again and everything is ok, in a matter of fact it was ok all the time. What was wrong was that I had not learnd the "driving rules".
Thanks for putting me right (and my confusing).
