I am trying to etch some things that need to be an exact scale. I have PDF documents that print to paper at 100% and are perfectly sized, however I am having a heck of a time getting the same from the Laseraxe.
I am using CNCC2019 V1.24 and a PDF of a "Printable Ruler" from here: https://www.printablerulers.net/
I can convert the PDF to an image (png for example) and this also prints on paper to the correct size, but not on the Laseraxe.
I have tried converting the PDF to gcode using Inkscape and importing the gcode directly into CNCC2019 but the scale is even worse.
What is the correct/best way to etch this attached file to end up with it being true to scale?
The PDF file is here: https://www.dropbox.com/s/upjya52jupqddyk/15-cm_ruler_mm.pdf?dl=0
