First, could someone post the Equation for Steps per inch. I have done a search but all posts seem to have a dielic in paragraph form.

1/8 microstep

Step Angle 1.8 degree (200 spr)

.200 pitch BallScrew

Second, my Softlimits are set up as X=8.5-max 0-min, Y=4-max 0-min, Z= 0-max -7-min. When viewing the table display, my Z axis depth boundary lines are not 7 inches they seem to be at a very deep depth like 30 inches. X and Y are fine (did restart program)

Third, For reference, I use 8000 Steps per inch, and calculated about .0136 for my backlash. Nook Ballscrew and standard ballnut not preloaded. Does this seem close? But yes alot of backlash. or after I use the correct Steps per inch will this be closer to .008 or even .005 (all axis's are tight )

Thanks Mark
