Title: Ballscrew mapping

Hello Guys,

I have a question yet again, how "operational" is the ballscrew mapping in mach3?

Thanks
Fernando

Haven't the foggiest. You won't find much if any info on it. I even went to the Wiki. Have been curious though and temped to fool with it just for kicks. Wonder if anyone has even used it yet?

Well i just went to the yahoo group and searched it for ballscrew mapping.

Apparently Art commented that people who used it actually reported it worked!
So good news... now to find a way to accurately map the screws. heheh

Laser calibration is the best, lots of companies do it now, try google.

Yup,
Some time ago i got a quote form someone that did that service.

it was 200dlls per axis on a ball bar test, (hard to think doing a ball bar test with just one axis)
it was 350dlls per axis with laser.

I dont know what it consists of. just measuring or helping you map your machine or what.

Fernando

Hmm........ ?
1?-So how you do use the pull down menu to enter hard data from a source other than feedback from  an encoder?
2?-If a curve is created based on a known start point along the axis, and you are not using encoders, will it still work?
