RealPoint follows pixel by pixel black areas and drag a line until it is in that black area. There are two differences: Folded Line and LineByLine. First one acts like scribbler and tries to fill that black area by zigzag, other one just draws across lines over the drawing where is a black area.
Outline just draws contour of black areas.
Scan makes half-tone pictures by dots with so called dithering method where in darker area are more dots and in lighter fever.
Point just instead of lines fills black area with dots.
And parameter Point says, how long that point or dot will made in milliseconds. It important for lasering dots, not so important for pens.
As with EleksCAM, downloaded from BangGood are not included VisualC redistributable files, you must download it directly from EleksMaker and there is file 'VC Install x32.exe'. Install it and EleksCAM will work. There is no need to install other included 'VC Install x64.exe' as EleksCAM is 32 bit version.
@Zax Thank you for all this informations and congratulations for your YouTube Channel and your job. By modifying the settings of the windows region and the language for unicode numbers, elsmaker works.
So I will be able to test it. But actually T2LAser seems more complete. I think that will buy T2Laser to go further in the use of the machine. For now, I will practice with CAM. Thank you for your help.
