The laser is breaking down the molecular format of the sponge.
sadly, you cannot stop it happening. as to cleaning it up?
not really any way to do it other than by choosing a different foam

I'm in UK
Wife had Pfizer - not too much of side effect, a bit rough
Me - AstraZeneca - real rough for 24 hours (I had covid at Christmas and ended up in hospital so feeling bad from the Vax was...
You measuring residual current (at the black wire from the tube) or on the actual PSU Chuck?
Flawless advice :)
In reality brother? No, if you are close enough to see what it going on you are close enough to lose eyesight.
The problem is power density, if something reflects off of a flat surface it will...
I'm not a man of faith but I pray that nobody here will be the last person to die of covid before the vaccine rolls out in force.
we are gonna be good folks, hold the line...dig in just that bit...
Like the fellas are saying, a TT 100 with a 60 watt tube will do a premium job of cutting 1/4 inch , great tube, quality beam profile , nice sharp edge cuts.
A great choice for a 1/4 cutter :)

Fibre is the wrong machine for acrylics, some plastics can be leeched with a fibre (think of keyboard keys) but in general fibre for cutting plastics is a no go.
when I get a bit of spare time (my...
Surprisingly many grades of stainless cut very well and give a good edge finish (not so much on a galvo but on a flatbed where you can have gas shielding) 316 (S32) is great, takes a bit of power but...
define "easiest"
The one that will give the best quality or the one that will cut quickly etc?
Hi Hannu,
Avoid letting customers near Fibres like the plague, the 1064 nm wavelength blinds for giggles (and the eye damage is permanent), safetywise for screens + public/customers you will need...
with a 30watt Fibre?
None of them, while 30 watts can cut very thin metal, the finish and general quality will be very poor (not to mention slow as molasses on a winter day)
Start thinking 500...
I know Jean + Phil well, I can say without any fear of contradiction those folks have forgotten more about lasers than I'll ever know. It will be worth the wait for sure :)
You get used to it after a while Clare :)
sounds good,
If the HT PSU ignites the tube on test then that is ruled out as that bypasses everything in the safety system.
Leaves the Low voltage rail supply and the main controller card

Your mirrors or final lens is loose...
On tube length, there is no real limit (other than beam divergence) BEFORE it hits the final lens (on many lasers the beam has already traveled several feet before getting to the tube, in the case of...
Look up viral loading
A well intentioned mask is going to trap all the viruses and amass them right in front of your breathing holes. Low viral load is survivable, high viral load is killing even...
Ghosting on Rastering is less likely, the material is subjected to a much lower power density per unit time.
Vectoring requires the highest power density per unit time, typically demonstrated...

Our English neighbors are panic buying loo roll
Us Welshies are all licking door handles trying to get two weeks off work :)
The English folks are losing their minds and panic buying Loo roll, Pasta and dried rice

Nylon doesn't ablate Bill, it just melts :) messy, even on higher powered machines you need to use high pressure gas to keep the cut looking good.
Lasers are duel use, routers aren't :) the D-Use is what gets lasers a hard time :)
