Partial success

Need to work on the hight of the bearing holders. The coupler is not the right size but it works and will do for now.

Failure

I think one of the kids knocked the build platform, not only that but the scale is wrong, a 608 bearing won't fit without fiddling. I think I might still use them in the prototype.
Printing the coupler. I will be using M6 threaded rod.

I think you're right, it's definitely not cutting as much as it used to. I'm gonna take a look at the TTL signal. I read the current by cutting the + lead to the laser and inserting an ammeter. I'll swap back to the old card and do the same thing.

You can trace the image or load the DXF to T2Laser, just set force override units to make sure the size is correct as the header seemed to be incorrect.

I have done that and it did load a create g-code. 849.24 line count, total distance nearly 589 meters and a 4+ hour time. I think there has to be a better method. Maybe I'll just get T2L to outline the image file I can create of the file.

You have to save it in a CAD program such as QCAD or LibreCAD or NanoCAD.

The copy of Inkscape I have will not output a new enough DXF that BCL will accept it. How do I change that or did I somehow obtain an older copy of the program?

I suspect your laser is only partially on. If those are real power numbers then nothing is being lost to heat and we know that the fan and heat sink are required for normal operation.

I did some measurements. At full power, the laser draws 0.65a and the supply is at 11.68v, for 7.59w. So I guess the advertised 10w rating of this laser is a bit of Chinese puffery. Still, 7-1/2 watts is nothing to sneeze at.

But that still leaves the question of why the two boards seem to yield different power levels. The laser doesn't drag the supply voltage down significantly. All I can think is that the TTL pulse width isn't quite going to 100%. I do have an oscilloscope so I may hook it up and see. But this isn't a deal breaker, I should be able to do a lot with 7-1/2 watts.

Google search brings up 12V @ 2A.
The button is probably a lower power mode.
TTL hookup to non-ttl ready controllers requires adding your own wire and headers.
I suspect you could wire the power connector to the power laser connector.
