I have started mounting a Mitutoyo 715 linear scale on the x axis of my 1100 thinking it might be usefull ..
Just saw some in Bob Warfields CNCcookbook series here he says:
"Another thing to be aware of is that a lot of machine control software, including Mach 3, has a feature known as “ballscrew mapping”. This feature lets you measure the true position reached at various points along the ballscrew and use it to compensate for errors in the ballscrew. This function works very well, and should be taken advantage of if you have the means to accurately measure the deviations. This alone is a good reason to install an inexpensive DRO at least temporarily on your machine until you can get the compensation tables calibrated."
I searched for "mapping" in the Tormach PCNC and pathpilot sections and didnt find any post son this......Am I missing some posts or is this yet to be considered here?
and does PP presently have provisons available for ballscrew mapping....
Probably later looking at using the linear scale's absolute positioning ability to improve over mechanical homing switches...?
at some point
Thanks
