Hello
So that they know a little how to find out that a laser diode is damaged.
I contacted the sculpfun technical service, since I had my recorder under warranty and they asked me to do the following:
1 Connect the laser head to the 5V socket of the card.
2 Focus the laser on a wall, approximately 3 meters is recommended.
Depending on how the laser comes out focusing, it is known if the laser is bad or good.
I am attaching an image of how the laser should focus correctly at that distance. Outside of that opening range it gives symptoms that the laser is damaged.
I got a very wide, completely rectangular focus, without concentration on the light beam, nothing to do with the attached image.
A 10 for the sculpfun support team who sent me a new one.
I asked them how it is possible that it has been damaged if I have hardly worked with it in a year, just little things with the little time I have and they tell me that due to different environments and engraving materials, the laser may also be damaged and the machine will not be used for a long time, which will also cause the laser to become weak.
I hope this can help someone to rule out doubts if their laser is or begins to be damaged.
