Using heightmap

[screwt]

Hello, and thanks for sharing LaserWeb4.
I was wondering if a height-map functionality exists in LaserWeb4.
Here is an illustration on what i mean by height-map functionality.

Hi @screwt
No, Laserweb itself does not have any height map functionality built into it.

What GrblControl is doing there is quite interesting, and sorta neat.

Height mapping is usually handled by the device firmware, rather than the controller program on the PC.

• Firmware height compensation is quite common. My Duet3d powered printer uses it, Klipper and others can too.
• It tends to be an 'advanced' feature only found on 32-bit controllers and not on the 328P grbl boards cheaper kits come with.

GrblControl has added a feature so it can probe the board and add the heightmap itself, by-passing the firmware. This is pretty neat (imho). LaserWeb does not have any equivalent feature unfortunately.

What you can do is generate gcode in laserweb in your browser, save it, then load it into GrblControl, which can apply the heightmap and run the cutting job.

• Laserweb runs in a web browser.. it's just a website. You can go here and generate gcode with it.
