Hi everyone. Probably a blindinly obvious question but…
I have just got an Algolaser DIY Mk 2 10w kit. I have put it togeher and the built in files cut perfectly. I have just installed Lightburn and nothing from there burns. The laser head moves as it should nd the laser seems to be firing but nothing appears on the plywood underneath. I have checked the focus and that is OK. Any suggest ions please?
You are very likely trying to engrave at too high a speed for your laser. A common error is having Lightburn set to mm/sec, where it should be set to mm/min. mm/sec is 60 x faster than mm/min and your laser is not capable of engraving at those speeds. Go to the Settings menu (Gears icon) and change to mm/min then try your test again starting at roughly 3,000 mm/min and 75% power.
NO, the settings were as you suggested. I have just noticed that I get an error in the transcript window
G-code locked out during alarm or jog state.
error:9

You need to determine the cause of this error. Copy the entire contents of the console window here. That may help us figure it out.
Also, Please post a screenshot (not a cell phone pic) of your entire Lightburn screen with your project loaded and the Cuts/Layers Panel and Laser Panel visible. Also post a screenshot of the Settings Window (Gears icon) with the Units and Grids tab visible and post a screenshot of the Device Settings Window (Wrench and Screwdriver icon). https://www.take-a-screenshot.org/

Oh wow. I have had to leave it for now as my workshop is very cold (it is supposedly Spring but it’s not getting warmer). I will go back in tomorrow afternoon and get all the screenshots. Thanks for the reply.

Well here is best I can do - I am usually on a Mac so Windows is a strange world.

Attached is a short video showing the laser in operation using Lightburn. As you can see, one of the test pieces on the AlgoLaser has burnt properly so it is only with Lightburn that I have the issue.
Since we have no idea what speeds the laser was running with the preloaded files, run a couple test grids. You should get some kind of output. Lightburn has presets for diode laser. Load those and change the speed for engrave to 1,000 & 7,000 and Cut to 60 to 1,000. Run both the engrave and cut tests and post your results. 6,000 mm/min may still be a little fast.
I enabled that. I then setup the engrave test using the parameters suggested
then got this result
None of the text appeared!
Here is the console list

I am getting concerned because I know that Algolser do not answer emails so I am beginningto think that I have bought a nice piece of engineering!
I think you’re doing ok.
I think so too…
The darker line on the left of the test patches may be indicating that overscan isn’t selected in LightBurn. It also suggests that the difference between the travel speed and the engrave speed may be a little high or there may be another issue with the motion controller.
There’s some really interesting detail in that console window capture that you provided.
The most useful data is probably the Machine Settings, particularly $30=1000.000
In LightBurn, open Device Settings (under Edit) and confirm that the value assigned to ‘S-value max’ is 1000.
Device Settings is also available by clicking the Wrench & Screwdriver icon in the middle of the toolbar.
Edit S-value max if it doesn’t match the value for $30. When finished, click OK at the bottom of that pop up window to ensure the setting in LightBurn is changed.
If Algolaser offered packaged settings for LightBurn to use, the S-value max should have been imported correctly. If your laser shipped with a usb drive, there might be a file ending with .lbset, .lbdev or .lbprefs.
Please let us know if you imported a file like that into LightBurn before your testing. If the file wasn’t imported some of the settings may be mismatched.
There’s a note about HPGL in the console data. I’ll ask internally if the Algolaser software is HPGL based. It’s possible that it can be made to make a difference in how speed and power are controlled.
Another member of our team noticed that your laser defaulted to grbl-LPC.
He generated a device profile for the algolaser device (off the cuff - from memory).
Before attempting this, you probably want to save your current device profile first. You’re close and you may want to refer to your previous settings.
In the Laser window in LightBurn, click Devices, click to select the device from the list, then click the Export button (bottom right). Select a file name and save this file somewhere convenient.
Download the attached file and save it somewhere convenient. (Next to the other file is probably handy).
Import the lbdev (LightBurn device profile) file using the Devices window in the Laser window.
After the file is imported, before closing the Devices window, click the ‘Make Default’ button. This should activate the new device profile when the window is closed.
Please let us know if this helped.

Change the s-max value in the machine preferences window to 1000. This is the reason it doesn’t burn.
