Movement Distance Not Correct.
recently i tried centering a shaft on my machine using a digitizing probe and i cant figure out why the DRO in emc is reading wrong ?
It reads about 0.040 more then the actual part size , why is this ? I tried setting the tool diameter to zero but it does not seem to help. The manual says its a scaling issue? I'm not sure what that means.
Thanks in advance
I had a shaft in the vise and started on one side touched down, zeroed, and moved to the other side. The diameter was out +0.040". I then checked a parallel in the vise for width along X , This time i got 0.066" over.
The docs said it could be that scaling is set wrong , not sure what that is?
Do you know the true dimensions of the vice and the parallel? If it always measures things 5% big then I would suspect an error in the axis scaling in the INI file (ie, how many steps it takes to move the axis an inch).
If the error is approximately the same regardless of the size of the thing you are probing, then I would suspect a mechanical issue.
