Transfer Failed - Lightburn 1.2.03

[Fireplug (Doug Stilwill)]

After loading a file, when I hit the start button I receive an error. It says: “there was a problem sending data to the laser. The machine may be paused or busy.” Everything is current, as far as updates, I just loaded the program a couple days ago. I have shut down all files except my browser. I tried to attach a picture of the open software and the error message, but it didn’t load properly.

Suggestions?

What’s happening on the machine itself? Have you tried power-cycling/resetting it?
Is there any info in the console window in LightBurn that says anything that might be a clue, such as an alarm state or that it’s already attempting to cut a job?

What laser are you using? And has it worked before this? If so, has anything changed?

Have you selected the COM port that your laser is connected to, and do you see communication between LightBurn and the laser controller before you try to run a file? If you don’t, you’re not connected yet.

In this window you might see ‘Choose’ here - click it, and try each option in turn until you see something in the console that looks like they’re talking to each other:

I have the D1 Pro 10W. Yes reset, no errors in any windows, other than the one I listed. No, I have not been able to get it to recognize my laser.

I have the COM port selected, but it still isn’t working.

“It still isn’t working” is very little to go on.

• do you see any output in the console window?

• does the computer “ding” when you plug the laser in and turn it on?

• has it ever worked? Like, was it working before and suddenly now it isn’t, or has it simply never worked at all?

“it still isn’t working” is a clip of an answer to all the advice I have followed.

This is a screenshot of what I get when I hit the start button.
I have downloaded the driver, the software version is current, in both Lightburn and XCS, I have the right COM port selected, I have my laser selected, my laptop “dings” when I turn the laser on. I forgot, it did move once when I hit the “home” button on the move panel, the laser head did move to the upper left corner and I haven’t been able to get it to do anything since.

Click the ‘Console’ tab - does it show any communication between LightBurn and the laser?

[Fireplug (Doug Stilwill)]

It says “waiting for connection”

Then you’re not connected to the laser. If you click where it says “COM3” do you have other choices? Are you still running other software that’s connected to the laser? (only one can talk to it at a time)

Try the “Enable DTR Signal” - you can toggle on this setting in Edit>Device Settings e.g;
