i'm sorry if this is the wrong section but i didn't know which one was the most suitable.
Hi everyone, I'm completing the design of my firstl aser engraver.
While for the mechanics I have already defined everything, I have some doubts regarding the electronics and its management.
Having to engrave on wood (poplar or beech plywood) and wooden boards, I would opt for a laser of 0.5 W 405 nm.
I found this KIT
for the laser and this other
for mechanic management.
I rely on your experience to solve my doubts.
The laser KIT is suitable to sustain only a modest number of hours of incisions (obviously not for continous usage, with necessary precautions) or is it likely to burn out after a few hours of use as it happens with many kits?
Are the KIT protection glasses sufficient and reliable for eyes protection?
Is the PWM system manageable with the CNCShield I have chosen? I looker for different sites but there are different types of recommended connections, also based on the type of PWM driver card.
The same laser KIT -as I understand- could be connected even without PWM, but only with an ON/OFF switch.
If I would like to cut 4mm woodden multilayer, which laser KIT should I choose?
If my proposal is not suitable, could you kindly suggest a valid (and tested) configuration for my purposes?
Your Post is very hard to read because it has no whitespace to separate the different parts. I think these are the questions

There may be some people using this Forum who have some advice for you but really, none of your questions is about Arduinos. I suspect you would be better off asking your question on a Forum that deals with cnc and lasers.
I have been wondering about the eye protection question myself and, while there seem to be lots of YouTube videos on the subject I did not get the impression that any of them was sufficiently qualified so I could rely on its advice.
I presume that more laser power = better cutting capability.
The laser engraver are based on Arduino uno and the cnc shield are connected to it
Then, i suppose that in this forum some people can help me for different think
First, choose a tested or valid configuration of hw compatible with arduino
Second, choose the hw based on your experience
I appreciate your advice for best write and i have added some blank space.
Sorry for my english, i hope you undestand my bad language

I was aware of that when I wrote Reply #1.
The fact that an Arduino is used as a controller does not mean that people familiar with Arduino programming will automatically be able to answer questions about lasers - for example, how long before the laser burns itself out or whether protective glasses are safe.
If it is any help to you I am thinking of buying one of these 5500mW lasers - but probably not for a month or two. The link is the first one Ebay produced and I am not recommending any particular supplier. Also, I have no idea whether the supplied goggles are safe.
