Graham,

I tried the formula function X*2 as suggested by entering this on the line for X in the formula axis correction box under functional cnfgs and it doesn't work. I tried it several times and also the same formula for y as Y*2 and it either does nothing or returns a dro as if no formulas were enabled. Also strange results where even though X1 is entered in MDI, DRO shows motion in A. When attempting test in formula axis correction box I get error found on position 1 General parser error blocked! So I apparently have a problem with Mach 3 and using the formulas.

Thanks, Woodeye
