Sorry big mistake !
It's not norwegian , its from SpiralFromImage script
from Krummrey.
I apologize once more.

Hi all,
I have machine created from UNO and CNC Shield controller.
Everything seems working fine but i write app for creating "norwegian" style for UNO using only C17 command and pen up and down of course.

But i dont know what is wrong. Generated code is OK but drawings not.
Seems to be skipped or missing motor steps. I'm using NEMA17 from Microcon. Bad tension in some areas ? / using T2.5 timing belts with 16 teeth pulleys/ or is it calibration ? Maybe servo lifting ?

I write small util to reread generated code back to image and all is ok.
Problem must be HW type i think. Any ideas? thanks.
