Our experience with K40 laser is that $100=157 and $101=157 are sweet spots for K40 laser x and y step distance. It’s a great idea to get started by typing $$ and copying and pasting the results to a backup document, so you can always go back to your existing configuration if you need to. The $$ command reads all your machine’s current settings. The Lightburn interface showing command line Useful $ settings The command-line is available in any G-code sender software.
It’s where you can click in the space and type in settings (or even directions such as G0 X150 directly). The command line is circled and highlighted in the image below. So the $ symbol indicates to the controller that the instructions relate to settings, and are not an instruction to move, burn or cut anything.
G-code controllers normally just receive movement directions, such as go to x position 150 at full speed is G0 X150 ( note there is no F or feed rate parm, it assumes the fastest feed rate e.g. If you need to change a setting that’s not in the user interface, you’ll need to use the command line to send $ settings to your controller. So why don’t all machine settings just get shown in a nice user interface ? Well, there’s quite a few settings, and not all of them are relevant to each application and every user, so designers only make interfaces for the minimum. Checking the box actually sends settings to your controller in the background, user friendly right ? Some of the easy to use interface for laser control in Lightburn software An example is shown in the image below, from Lightburn software, where the Laser mode enable can be set by clicking a checkbox.
The best case scenario is that you can adjust the settings you need in a nice user interface, without learning manual configuration via a G-code sender. And if you’re building your own laser or CNC, you’ll need to know all about controller settings. Even if you’ve bought a pre-made laser or CNC machine, you’re still likely to benefit from fine-tuning the settings for your materials or needs. The brains of laser cutters and CNC machines, G-code controllers, include settings covering speed, physical limits, directions and intensity (of a laser beam, or rotational speed of a spinning endmill).
