Problem with scale? Stepconf/axis

I configured my machine using axis. I used numbers provided me by manufacturer (with some calculations I had to do to "translate" from manufacturer parameters to emc2/axis parameters).
Math I have to do was to translate manufacturer "axis resolution" to leadscrew pitch in stepconf.
I have got 266.66 steps/mm , my stepper has 1.8deg/step (so 200 steps/rev).
I calculated that leadscrew pitch should be 0.75001875 (and it gives axis scale 266.7 - rounded up, I guess).
I have tested axis and everything looked working fine.

But when I started to use emc2 / axis, it looks like that all distances are scaled down by 2 (approximately).
I tested it for both G20 (inches) and G21 (mm).
I do not thing that it is a problem with microstepping or gears (I have stepper directly connected to leadscrew) because testing axis in stepconf works fine.

Could you please help me find what could generate such strange problem?

I attached my stepconf file.

Thank you in advance!

To be precise - real machine moves like all distances were scaled down by 2.
Axis shows correct distance.
For example: G0 X20 gives me a distance 20mm in axis, and 10mm on real machine.
But testing config in stepconf 20mm gives 20mm on real machine.

Ok. found it Sorry...
Stepconf shows +- , so distance has to be counted twice ))))

It looks like the manufacturer "lies" a bit in documentation. Among others there were parameters for smaller version.

I have got machine with license for PC-NC software and settings for this software.

From my calculations from parameters given by manufacturer it looks like that leadscrew has 0.75001875 mm pitch. I measured it (from "tooth" to "tooth") and it looks like it has 3 mm.
In the other hand emc2 works fine with 0.375 setting and without microstepping.
I tried settings with microstepping but I configured something wrong and my machine has started fast like creazy and blocked.
So I will rather stay with 0.375 and no microstepping.
Maybe manufacturer modyfied a bit construction (steppers, drivers, leadscrew) forgeting to update documentation
I am pretty new at CNCing (moving from reader/story-teller to practicioner )
I will asked them in near future. But currently I am happy with my first success with configuration and trying to find appopriate bits to PCB milling (first approach failed - I broke bits trying to touch off :/)
Thank you for your suggestion!

I like your solution.
Thank you for great tip!
