NEW VERSION OF THE ONLINE G-CODE GENERATOR AND VIDEO MANUAL
I saw a lot of similar design, but nothing worked well for me.
So I decided to design my own.
I did a lot of variations of standard designs and a lot a lot of tests.
The result is here. :)
It is small and it works like a charm. :)
I did already a lot of prints and still without any problems.
