Drivers for Connecting the Controller to your computer

If you don’t see the computer find the USB port and you can’t connect, then you might need to download these drivers. If you are running the new 32 Bit J Tech Controller on Windows 11, then you will need to install the drivers for the USB Chip. You can download them here:

CP2102 drivers for Windows

If you have a mac, you can get the drivers here: Silicon Labs Mac OS Drivers

Lightburn Setup Video

This is the video on how to set up Lightburn with the new 32 bit controller. Make sure you have your USB cable connected to the machine to run this project.

Changing Modes with Macros In Lightburn

This video shows how to make macros in Lightburn to change the acceleration of the machine. Doing a Raster based engraving you can go a lot faster with minimal vibration. For line mode, you might need to reduce the acceleration to get cleaner and more detailed finish on the engraving.


Sometimes it is necessary to update your configuration file that is on your machine. Good news is it is not that hard to do. We have the current configuration file available here in this link so you can update and make sure your machine is running with the newest version.

Once you download it from the J Tech website, you can then upload it to your controller using WiFi. Instructions on how to do this are in this video here:
