SUCCESS !
I upgraded the firmware on the xTool D1 to “V40.30.002.01B1_20220110” and now it works with LightBurn.
Following the instructions here How to upgrade the xTool D1 firmware provided the neccessary application and files to perform the firmware update. Just remember to enable the Update Firmware Switch on the xTool D1 controller board before starting the upgrade and be sure to dissable the Update Firmware Switch when the upgrade procedure is complete. Then cycle power on the xTool D1 before starting LightBurn.
The “Check for Firmware” button within the Laserbox Basic software did not recognize the need for an update. After researching several websites and documents and suggestions from this post, it seemed logical that the firmware on the xTool D1 was not up-to-date. Using the Firmware Upgrade Tool from xTool worked.
Below is the first project I ran from LightBurn and it turned out perfect.
That is a 4" round coaster that is 5mm thick. The settings I used in LightBurn were 112 mm/s at 25% power with no air assist.
Now I feel confident in purchasing the LightBurn software. I just need to learn it inside and out now. Wish me luck. I’m certain I’ll be visiting this forum frequently for guidance.
Huge thanks to all of you that participated in this post. Hopefully this info will help someone in the future.
