Reverse writing with Creality Rotary roller

Hello.
I test for the first time the Creality rotary roller with my Falcon 10W engraver and LaserGRBL + Inscape ==> output = *.svg file.
I think I connected correctly the roller to the engraver.
I changed $101=60.375 as mentionned in the document.
When I engrave the writing is reversed, I joined the picture of the result.
What did I do wrong ?
Thanks for your help.


Humm I turned the roller 180 degrees and the writing is now correct.
I will use this bypass until someone gives me a better way to fix.
