I was working on some issues with the lathe today and discovered that what I thought was a 1:1 relationship between the pulley on my spindle motor and pulley on the spindle head - is not. The diameter of the spindle pulley is 4.2125” while the spindle itself is 5.175” (they are probably actually 107mm and 130mm or thereabouts). This give a 0.833 ratio and explains why 3500rpm is actually spinning at about 3000rpm according to my tach. I am wondering the best way to let Linuxcnc know that this is the case so that commanding 3000 gives me 3000.
