Delta kossel laser

This is my version to equip a 3D printer with a laser head.
Two objects are offered, a platform with magnetic attachments and a laser head holder what is attached to the platform.
Magnetic mount project can be found here:

I am using a 5V 1500mW laser which was previously ordered from Aliexpress: https://www.aliexpress.com/item/33019893763.html?spm=a2g0s.9042311.0.0.27424c4dgifHtx

To attach the laser to the trigorilla board, I soldered a small transition circuit shown in the figure, for PWM support to laser. NOTE, in my case the laser works with 5V, but to drive the fan, the board is giving 12V. I soldered the main power pins for PWM - 5V and GND straight to the 3d printer board, but it turned out that the whole 5V bus is connected, which means that you can connect anywhere where 5V or GND is marked, the PWM signal line is connected to 12V output "FAN 0". If you use a different type of laser or 3D printer, the connection may be different or you can use it directly from this 12 V port.

To prepare the material to be cut, I use the INKSCAPE program with this extension: https://jtechphotonics.com/?page_id=2012

With Pronterface, I adjust the height to get the laser focus point.

M106 enable FAN (LASER), but M107 disables.
with command M106 S255 switches on maximum power.

The printer software itself has been updated with the latest marlin 2.0.5.3 software. There is a doubt that delta leveling doesn't really work, but with newer versions or bugfix it should be ok.

A circuit was also created to switch from a fan to a laser, as access to this port is difficult and inconvenient.
