Good point, I am used to machines where that can be assumed. Not the case with a fabricated gantry router. Distance from fully-retracted spindle to table at various points will tell you how the table aligns with the true X/Y plane. There might be a work sequence somewhere on the interweb which runs through the optimum sequence for aligning such a machine. I have never even seen one in-person. (I will be putting some of all this in practice this weekend, we are moving my dad's machine tool collection from the temporary to permanent workshop. http://www.lathes.co.uk/smartbrown/page6.html http://www.lathes.co.uk/colchester/page14.html http://www.zhongyang-engrg.com/photos/se8089.jpg http://www.scottmachinery.co.nz/dbimage.php?meth=norm&img=BORE-1-0003__1 Likely to be a long hard weekend. Even the saddle of the borer is the sort of mass you can't even move by hand.) -- atp ------------------------------------------------------------------------------ Join us December 9, 2009 for the Red Hat Virtual Experience, a free event focused on virtualization and cloud computing.
