Balsa sheet cutting with 2.8W JTech

[StevenDomenici]

My J-Tech 7w cuts 1/8" Baltic Birch with ease!

Really lol It takes forever, I have to take 10 passes at 250mm to cut through

[StevenDomenici]

That’s discouraging! How’s your focus? At that speed and 60% power, I could cut it in 2 passes. Too much charring though. I’ll work on some speeds and power settings today. I just got my new one yesterday.

Well I’m cutting at 100% power and 250mm a minute and I think I’m focused

12IPM? My machine only reads mm, and what watt is your laser?

[ShaneJamerson]

You can change the unit settings in lightburn.

And 7W laser with HD lens.

HD lens? What’s special about it?

Hmm so it’s the same as a G2 lens from what I’m reading
