I was on Banggood buying some other stuff and this came up on sale
So I snatched one up.
I followed the instructions for the 2.8watt laser and they apply to this as far as Marlin and hooking up to the RAMPS. The pots were apparently pre-adjusted because they were glued. Figured I’d give it a try as is. Works just fine. Fan speeds control the power of the laser. Laser starts to fire at fan speed 3 and full power at 255 as you’d expect.
Just wanted to share if anyone wanted to try out a $65 laser… Came with everything including the glasses.
The transistors did get a bit toasty on the driver board but the laser module itself seemed to barely get warm. I will come up with something to work on those heat sinks. Also need to come up with a mounting solution for the CNC or find a workable one on Thingiverse.
