Problema nel settare la potenza, velocità e fuoco

Ciao di nuovo a tutti, son ancora al “getting started” sembrerebbe.
In pratica non riesco a trovare un settaggio che non bruci il legno come invece sembrq fare.
Ho un atomstack 24W e ho settato il fuoco col spessore in dotazione. Ho la pompetta dell’aria aperta che soffi sul taglio (non so se regolandone il potenziometro influisca in qualche modo perché mi sembra che lightburn bypassi quel potenziometro). Su compensato da 4mm il risultato fronte retro è quello visibile nelle foto. Allego anche il file test usato vista SVG e vista da lightburn con relativi parametri.
È tutto troppo bruciato, addiritura la scala laterale me l’ha staccata mentre stava ancora incidendo (ma quello sarà un problema di priorità di taglio?).
Ho provato a mettere il laser 1mm più in basso dello spessore, di tenerlo un po’ più in alto, non capisco quale sia il problema (se invece è tutto normale allora mi arrendo).

Hello again everyone, I’m still at the “getting started” it seems.
Basically I can’t find a setting that doesn’t burn the wood as it seems to do.
I have an atomstack 24W and I set the fire with the thickness supplied. I have the open air pump that blows on the cut (I don’t know if adjusting the potentiometer affects it in any way because it seems to me that lightburn bypasses that potentiometer). On 4mm plywood the front-back result is the one visible in the photos. I also attach the test file used SVG view and view from lightburn with relative parameters.
It’s all too burned, it even detached the side ladder while it was still engraving (but is that a problem of cutting priority?).
I tried to put the laser 1mm lower than the thickness, to keep it a little higher, I don’t understand what the problem is (if instead everything is normal then I give up).

vabe che il legno forse era anche un po’ imbarcato?

ok, maybe the wood was also a little warped?

la vista del file in svg la allego qui perché sul commento iniziale ho già allegato 4 foto e non si puo di più

There is way too much heat put into the material.

Double your speed AND cut the power in half. Did you try to use the Lightburn Material Test to get an approximate range of settings for that material?

ohhhh thank you so much for answering. Actually I have an old LB version without the possibility to make the test material. I found this test online.
I’ll try doing the settings you said. Actually I already wanted to tweak with the settings but I’m not skilled enough to do anything but random for now so thnks for a direction. So 800/40 and 12K/10 right?

800/40 and 12K10 what? Without units this is meaningless. What you presented is not double or half of anything.

Those numbers do seem to indicate you are using mm/m in Lightburn, which is good for a diode laser. for comparison, my 40w/20w laser 20w setting cuts 2.8mm Baltic Birch plywood at 1200mm/m, 80% power, and 4 passes. Etching is at 3000mm/m, 20% power, and 1 pass.

These should get you in a range that you can see results you can adjust.

I was talking about speed and power as you said to double the first and halve the latter. Now for the black parts it’s set at 400mm/min and 80%power
so I should set it to 800mm/min and 40%power for 4mm thick pine plywood… 1 pass also. Now it’s night here, I just came back from work, tomorrow I’ll try these settings and those you suggested in your previous comment

ok so I tweaked a bit with the settings and this is the result on 4mm plywood. It seems your settings are in fact the best ones (lines 1 and 2) but the first line is still “smokey” on the back, is it normal or do I have to do something else?
PS: i have a matrix panel, not a honeycomb, to support the wood. They said it’s better
PPS: and the machine is atomstack 20w

up, no ideas? Or is it normal?

wow… don’t fret, so many answers!. Ok, I write in english, there’s a trnslation, IS THERE SOMEBODY WHO CAN HELP?! Hello?

The variability in organic material makes material testing is one of the most important steps. The engraving settings can also be adjusted to personal taste.

There are several ways to manage smoke staining.

Some people prefer to spray lacquer on wood before engraving.
You can manage an exhaust fan to direct the smoke away from the work.
You can use masking material to keep the smoke from staining the wood.

wow so many solutions I didn’t know, so there ARE some precautions you guys normally take, nobody said that, in every video they just place the wood and start… I have built a good enclosure for the cutter, on a custom table, with an air assist and a pump to extract smoke through a filter. It seems the tweaking on the 1st line are giving the best results at the moment though. Thanks for helping (and keep on doing it lol, I’m not done yet)
