This I did read. Still not getting the meaning of life and everything....

What is this odd number? And why should I take that as a unit?

What do the _two_ numbers represent? Why use INPUT_SCALE (I do not
have feedback via DRO)?

Again, what do the two pairs f numbers represent in laymans terms? For
what real pitch and stepper motor would this example apply?

Sorry to bother you with my ignorance again. I do not get the curve here.
How can I apply the above to my setup? I have a metric leadscrew with 5mm/rev
and 200 steps/rev motor. how does this tie in to the conf.ini in the axes
section? (I hope I can work out the 1,5mm/rev and 200steps/rev z-axes
myself then)


Thanks and best regards,
