Hi Richard,
No fear of doing that my friend - ask as many questions as you need.
From your calculations it would appear that your stepper driver is set to 1/8th microstepping.
I don't know the exact figure (I am sure that someone here does) but Mach3 supports a precision which is many times greater than the accuracy of any of our machines so you just need to resolve this Z axis steps issue you are experiencing. I think we have mentioned it before but you have thoroughly checked all the mechanicals for loose grub screws, slipping coupler, etc., etc. ??

Sorry, I know I've asked a lot here. Thanks to anyone that helps. Tweakie and RICH have been great to me, but I don't want to look a gift horse in the mouth.
