there's gotta be something wrong with RF people

@macona now I have pressure suggestions in all ranges 😅 I guess it depends on everything else and I need recipes per nozzle per material 3.5 psi: youtu.be/Rlf3UzY5Hu8?t=… 8.7 psi: manufacturer suggestion 22 psi: youtu.be/29xY4gch6fs?t=… 36 psi: youtu.be/BsHLxEhNU68?t=… hundreds of PSI

@MarcoReps FWIW, I use a much smaller one which gave me significantly better results. But I have no idea what is available for your machine. The bystronic that was at one of the places i worked at in the past used very high pressures in thr several hundred PSI range.

Are there any experts on oxygen-assisted fiber laser steel cutting here? I can't seem to get this thing to behave. My best results in 6mm mild steel came out of 0.5 bar, 90% power, 15mm/s, 0.5mm standoff, -2mm nozzle focus, and an excessively long initial pierce to be safe

@macona yes this uses a standard M11 nozzle thread, but I only have 1mm and 1.2mm in stock rn, both behaving very similarly

@MarcoReps Can you change nozzle size? I have found on my little co2 that nozzle diameter makes a big difference when cutting steel.

only suspect left to check: the focus following. capacitive distance sensing in the midst of molten metal, plasma, sparks, blobs of dross, extreme heat .... sound like a nightmare for electronics, maybe it gets confused and oscillates?

I suspected my cheap oxygen pressure regulator at first and got an electronic SMC one (no regrets, it's cute) but it didn't fix it. When cutting circles I get different landscapes in the walls depending on direction, which points towards poor beam centering, but it seems good

POV: you are a highly trained professional and you've been given a yellow crystal on a cart to shove into the anti-mass spectrometer

Visiting something very cool in January so I finally upped my camera game 🥸 Although it will be hard work to carry this monstrosity in one hand all day long

at least it's not the Hirschmann Micro-Kleps

How long do I have left, Doctor Twitter?

@SchizoDuckie noted thank you! but! don't building materials nowadays have to be flame-retardant and self-extinguishing?

@MarcoReps If you've ever seen the glue layer of laminate burn through you'll never do this again. Don't. Please. Once the glue layer catches fire it burns like a lithium battery, spewing flames. Source: I may or may not have burnt a whole german house worth of laminate back in the day.
