My Gantry weight is pulling the router head down by .007" when at the middle of the X-axis run - so I'm using the Functions section of MACH 3 to correct the Z-axis as the X-axis makes it's run.
Hi, i'm trying to use the ARCSIN function in mach3 (in the functions area):
(arcsin(sin((x/37.3)*PI)))/(arcsin(sin(PI/2))))*1
But, what is the command within MACH3 to perform ARCSIN ???

Ah, after some trial, I found I had some bracket problems - the ARCSIN command does work. Also, I have to use 3.14159 in lieu of "PI".
The formula works GREAT! dead center of my run I have the Z-axis raise by .007" and back to zero on each end!
