Salut Alain,
Je parle certes le français, mais à l'âge de 10 ans, nous avons déménagé en Suisse alémanique.
L'écriture est donc mon point faible. Mais grâce à DeepL.com, j'ai moins de problèmes🤣🤣.

Concernant le contreplaqué au laser :
Jusqu'à 6 mm pour le contreplaqué normal, mais pour l'okoumé, le bois ne doit pas être froid. De plus, tu dois calculer le double de coupes (passages).
20 watts est préférable, mais il faut savoir qu'il y a une ventilation supplémentaire à la pointe du laser. Tu peux l'acheter comme accessoire.
si tu as encore des questions, pose-les
Si tu ne poses pas de questions, tu n'auras pas de réponse ! 😊😊😊
A bientôt
Michel-Claude


For my English-speaking friends

Hi Alain,
I do speak French, but when I was 10 we moved to German-speaking Switzerland.
So writing is my weak point. But thanks to DeepL.com, I have fewer problems🤣🤣.

Regarding laser plywood:
Up to 6mm for normal plywood, but for okoume, the wood shouldn't be cold. What's more, you need to calculate double the number of cuts (passes).
20 watts is preferable, but be aware that there is additional ventilation at the tip of the laser. You can buy this as an accessory.
if you still have questions, ask them
If you don't ask questions, you won't get answers! 😊😊😊
See you soon
Michel-Claude

Hello
Many thank's to share your knowledge. One more question : what is, according to your experience, the maximum thickness is able to cut a 10w laser ? And the same for the 20w machine. Both for okoume plywood
Regards
Alain

Hello everyone,
It doesn't really matter which brand you choose. The important thing is that the appliance cuts cleanly and that you pay attention to handling. Also, the private place where you want to work should be properly ventilated or even have a self-made ventilation system, as I have with mine.
atomstack was recommended, there is also Vevor / Creality Falcon / Sculpfun etc. etc.
If you want to work commercially, the price is from 2000.- to over 15000.- Fr/€.
Even today's cheaper models have become better . . .the price has also adapted!
But for us model builders, a handy device is enough, so it's more in our budget, which our wives are sure to approve of!🤣🤣🤣
For me it was clear to build my model myself, which I also found on Ricardo.ch. Fixed models can, for example, have the guides cleaned or the toothed belts not tightened.
All in all, your wallet decides what you can buy, it's better to wait and save a little and then pay more for a better machine.
for today "end of fire"
Good night, your Michel-C.
PS: Picture = after new Year

Thanks Mike,

I will have a look at the possibilities and prices in my region.

Robbert

I'd recommend atomstack. Mine works beautifully and I only paid £140 about a year ago.
Take a look as they do happen to have sales sometimes.

Another thing Robbert,
I can give you the cutting data.
But I recommend that you draw a few rectangles and circles of the wood in question and enter different cutting thicknesses and speeds. Okumé wood, for example, is really hard and you need full steam or 100% laser power. Any other general questions?
Greetings Michel-C.
Ps: I also have an air pump that helps with the jet so that it is cut more cleanly by the cutter

Hello Robbert,
Gladly, here are the dates
It is a small 350 x 350mm laser cutter
Genmitsu Jinsoku LC-40 with a 10W laser.
I have also bought a 20 watt laser head, which I am now waiting for.

The whole appliance is built into an IKEA kitchen unit with ventilation, honeycomb support and a door switch that pauses the laser operation immediately when it is opened.
The door is protected against laser beams with an additional special glass plate. So you don't need safety goggles. The whole thing is mounted on table supports at working height. You can control it with Lightburn, which I think is very good software.
I still work with 2DCad and create dxf files there.
You can also use jpeg/bmp/gif/plt etc.
The only thing is that you have to buy Lightburn. You can just not have a few beers after work, but I think you'll want more and quickly forget the beers, like me!

Hi Mike,

Just found your posts and I am really curious about this machine you bought.
Can you share info about the brand and type please?

Regards, Robbert

Hi Mike, we often learn more from mistakes than successes.
I follow your explanations on laser cutting with great interest.

My latest experiences with the laser cutter are positive, but sometimes also humiliating . .
I simply forgot that cold plywood is very difficult to cut. This is especially true for okumé plywood! And also in the cold on the balcony . . At only 5 degrees???
I didn't want to fog my wife with smoke, so I moved to the balcony. I'm working on the Mississippi steamer hull at the moment anyway . . .
As I said, you never stop learning . . You forget the side effects because of all the joy, what the heck!
Greetings from Michel-C.
