need help cutting 1 mild steel
(OP)
Hi im fairly new to this laser thing as out company. Bought laser two years ago and guy that was running it quit a year and couple months in. Really seems like this thing hates 3/8,1/2 and one inch. But really cuts the rest fine? MY 3/4 is awesome thats what confused me? Our machine is a mitsubisha 3045 lpv plus i believe something like that. Don't have a lot of confidence in our reps. they just don't seem real sure about what there doing? What do most people use for gas? I know somebody talked about about a nitrogen generater but do we need one? Also seems like my beam is always change positions? My cutting parameters are something like 3300 watts and like 24 ipm and gas is like 1.2 with a Type 8 nozzle is this close or am i all messed up with my setup?

Nitrogen generators have their place, but are expensive. Also cuts with a genorator can change the edge discoloration as flow changes (high flow = worse discoloration). Makes most sense for beam path purge.
If your beam is moving, is your lens tight?

Thanks.

If you own a machine, you can download cutting conditions right from the website. There are many pierce routines. It depends on which one you use. You can talk to the training department.
That much movement on BM is too much. That site also has the latest info on alignments or call into the help center.
Hope this helps

I'm pretty sure that you mentioned your ¾ was cutting well. If that is the case, in that situation, I would tell my clients to use the exact same set up to cut 1". The difference being the feed rate. Just slow it down by 25-30%.
I'll state the obvious, steel quality is extremely important. There cannot be any scale on the top surface and the alloy should be homogenous. You have to correct you alignment issue. If money is tight, there are 3rd party service parties available that are often better than the manufacture's people.
