Thanks, glad you like it :)

I have a trotec 360 speedy flex and use a 2,85 lens. I have tried a lot of different settings and 100 power, 7 vector with an offset of .08 seems to do the best job...but no matter what I do it end up looking either light or dark brown and you can feel the annealing. I want to get this black color without any changes in the metal. Do you suggest anything to help? Ive tried everything from 20k hz to 80k hz. 55k hz gives it a really dark brown but it isn't the black im seeking.

Hello Robert! Thank you for your question. If you still can feel the marking, the power is too high. Also, there is no complete black when marking stainless steel with our Speedy machines. There is always some brown left (process- and material-related heat distribution, type of process, ...). You can get a complete black with our Galvo laser markers, which were designed especially for marking metal.

What is the "pre-spray" that you mention?

When we are talking about the "pre-spray" we talk about our "Laser Marking Solutions": www.trotec-materials.com/supplies/laser-marking-solutions.html If you only have a CO2 laser, you can pre-apply this sprays or pastes to mark metals. Here we have described the process: www.trotec-materials.com/material-usage-hints/marksolid-marking-spray The link goes to the international website - if you need such a spray or paste, please select your country webshop right here on the homepage: www.trotec-materials.com/

CO2 laser requires treatment of stainless steel in order to mark it. Correct? The fiber laser in your galvo style can only anneal and engrave. Correct? The difference in galvo and flatbed is speed, the end product is the same. Correct?

Yes, partly yes and it depends :) To mark stainless steel with a CO2 laser, its surface needs to be coated (e.g. anodized aluminum) or treated with a marking spray. The fiber lasers in our Galvo systems can mark in different ways. They can engrave and anneal, and also remove coatings or "stain" material. Check out this article on our website covering these marking methods in detail: www.troteclaser.com/en/knowledge/faqs/how-to-laser-mark/ The difference between Galvo and flatbed lasers is the speed and the size of the work area. Depending on the products you want to engrave or cut and the volumes you want to do, sometimes a Galvo and sometimes a flabed laser with a bigger work area can be faster. We'd have to look into this in detail for a valid recommendation, which system is the faster one.

What ppi is recommended for fiber stainless?

The frequency is specified in Hertz (Hz) for fiber lasers (not in ppi). It depends on the laser power of the respective machine and on what exactly is to be done (engraving, starting ...). Therefore there is no standard parameter. The print job is sent with a resolution of 1000 dpi (if that is what is meant). We hope that this will help, your Trotec Team
