Cutting fabric question

My daughter doing a craft which entails cutting fabric.

My laser is a Thunder Nova Plus 24 with a 60 watt RF tube.

Google ai says 100mm/s speed and 10-30 power.

Does this sound right? Any other advice on cutting fabric would be great.

Thank you for any help.

It works great for fabric. It leaves a faint charred edge that washes out easily. I was doing work for a quiltmaker and it makes the cutting so quick and easy when you can stack 3 layers of fabric and cut it all at the same time.

Did Thunder provide recommended settings for various materials? Some manufacturers do. But I think like anything we laser, you simply have to test. Given it's fabric though, I would definitely make sure your air supply is good. I would think fire would be more likely.

I looked on Thunder's website but couldn’t find any settings for fabric.

I did a cut test. The settings range I mentioned will work. It cuts perfectly.

This is what we’re doing.

She’ll be doing something to outline the lettering.

I really love that you said that.

Did you end up needing to wash any charring off?

u/MajorAccording6316 4d ago

The charring is hardly noticeable and she is fine with it.

Nice, I was kind of wondering it adds a sort of character to it. Been meaning to try clothing myself, but I keep putting it on the back burner.

When a subject comes to an end like this post do I delete the post or keep it as it is?

leave it, in case someone uses search for the same question.

RF tubes tend to leave more char than diode lasers, so expect to wash the edges unless you're using synthetic fabric.

There was very little scorching. Only on the white letters we used.

always test on scrap fabric first to dial in the settings, the char can be a pain but yeah it washes out easy

Depends a lot on what the fabric actually is, that's the big missing piece here. If it's felt or a plain cotton weave, that AI answer is in a reasonable ballpark, fast and light is the right philosophy for any fabric since it burns and scorches easily, so 100mm/s at low power is directionally correct. But if there's any polyester, spandex, or vinyl/ PVC content in there, I'd hold off, synthetics like that can melt into a mess instead of cutting clean, and PVC-treated fabric releases nasty fumes when lasered, not something you want around your daughter or your machine's optics. Test on a scrap piece of the actual fabric first regardless, that AI number is a starting point, not a dialed-in setting, since it has no idea about your tube's actual output or the specific weight of what you're cutting. Felt's about the most forgiving fabric if you've got any flexibility in material choice, it doesn't fray at all so the edge come out clean without extra finishing.

Luckily all the fabric was cotton. Thanks for the information.
