Gene, The new screws (if single start) move the axis almost twice as far per step (2.5mm vs 1.27mm) so the new scale will need about half as many steps to move one inch.
So new scale = old scale x 1.27mm/2.5mm or old scale x .508 New scale = 64000 x .508 = 32512 You could also approach the problem by saying that the new screws have 10.16 tpi (25.4/2.5) so the new scale would be old scale x 10.16tpi/20tpi still comes up 64000 x 10.16/20 = 64000 x .508 = 32512 Cecil >My mill's old XY screws were 20 tpi acme's and have now been replaced with >2.5mm pitch ball screws. >The current scale is 64000 in those 2 axis's. Is there a quick and dirty >way to convert that 64000 to the new screws value? ------------------------------------------------------------------------------ Open source business process management suite built on Java and Eclipse Turn processes into business applications with Bonita BPM Community Edition Quickly connect people, data, and systems into organized workflows Winner of BOSSIE, CODIE, OW2 and Gartner awards http://p.sf.net/sfu/Bonitasoft _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
