when an inch isn't

Hi,  trying to get the travel to actually measure correctly. 

I have entered:
200 motor steps
1.9 microstep
pulley 1:1
max velocity
max accel 30

Right now an inch measures 1.016"

What is my next step?

Cheers!
 

1.9 microstep

Microstepping is usually a number that is a power of two (ie 2,4,8,16).

Your .ini file would help.

Technically an inch is actually defined as 25.4mm, this came about in the 1930 or so as different regions had different definitions. The development of slip gauges or "Joe Blocks" had a bit to do with this.
I still can't understand why some regions of the world will attempt to use anything to avoid using the metric system......Yes it's as big as 3 football fields and as deep as 4 school buses.

en.wikipedia.org/wiki/Inch

Tho it makes no reference to slip gauges.

Leadscrew ptich is required or the numbers mean nothing (or if belt drive belt pitch)

Look at geometry and lost motion.

Remember that the distance between London and Paris is the same whether you represent it in kilometers or miles. The only difference is the way you slice it.
