Settings for suede and very fine leather.

[JamesW]

Hi All,

Anyone got some good cut settings for thin suede or very fine leather?

This afternoon I spent two hours testing some very, very thin suede. (around 1.25mm) It cuts, but as soon as the laser strikes it, it shrinks. So you need a VERY low power setting. I've ended up with 15% power (60W) 15mm/sec and three passes.

This is tedious, and I don't like the quality of the cut edge.

Looking online, some forums have suggested adjusting the PPI (I'm assuming this is "Pulses per Inch"?) which may be achievable by tweaking the laser frequency. Mine's set at 20,000, and I tried 10,000, which, I'm kidding myself, marginally improved the cut quality. Usually I don't ever change this setting, but having tried everything else...

Cutting this material MUST be is an achievable task, and I want to know how you do it. Any tips?

Cheers,

James

I may be wrong but the PWM setting is for RF tubes and not CO2 glass tubes - changing it may damage the tube!

If you increase the speed it should help - 15mm/sec seems very slow.
