Title: Strange Axis movement
Post by: dwrightny2266 on December 31, 2015, 09:55:47 AM

Setting up a new controller, and i noticed that all axis don't return to the same position that the left from.  For example 
Starting at 0
G0
X 5"
X-5" (expecting to be at 0)
But ending at -2" on both x and y axis.

Any ideas?

Are you sure that you're in incremental mode?

When you do X 5, does it go to 5?

Either your steps/unit is wrong, or you're losing steps.

It will move out in one direction 5" but return in a different measurement.
In the General Logic Config Panel, the distance mode is Absolute, and IJ in Inc.

Need to learn more about it. Still in learning mode lol

X-5" (expecting to be at 0)

In Absolute mode, this should end up at -5, moving 10"

 Should I normally be in Abs or inc mode or is that not a simple question to answer?
?

Most people use absolute most of the time.
But each has their place.

Like anything else, the more we know, the more we find that we don't know :)

Thanks again.
