Licensing Return to top of page

There is a 30 day free trial with no restrictions on the software. The trial version will work with all supported hardware.

LightBurn software purchased via CTR (i.e. with the purchase of a new laser machine system) will include all published updates and bug fixes for a year. After that first year, the software will keep working as is, but won't be eligible for further updates. If you want additional updates beyond the first year, a small renewal fee will get you another year - please contact CTR for pricing information.
Regardless of whether you decide to update or not, the version you have will keep working forever.

You can install the product on up to two machines (computers or compatible devices) at a time, so people with Mac/PC setups, or a PC in the house and one in the shop will be covered. Licenses can be transferred between machines if you get a new PC.
