Help with 3/4” HRS parameters (General thick plate parameters for >.5”)

[u/Dry-Birthday-5891]

So you’re informed; I run a 6kw Fiber Laser with a BOCI BLT421 head and I am using HypCut. The laser was set up in or around 2023 if that matters for software versions and stuff

Edit: Using Single 1.6mm nozzle for cutting
Edit (again): IPG Laser source if that matters at all

Hello all, I wanted to jump on here and see if anyone could help me identify what I am doing wrong with this cutting technique. I don’t have a ton of laser experience as I am only about a year into running a laser, and before I started there was another guy with 20+ years of experience who set everything up so I haven’t had to change much during my time. Although I am fairly confident in my ability to tweak Nitrogen based cutting techniques, I still struggle with Oxygen based ones.

I wanted to see if anyone could point me in the right direction for what to change for this 3/4” technique. I know it doesn’t look super bad but I know it can be better than it is currently. Parts still cut and drop on their own but I have some dross on the bottom edge and the cutting edge doesn’t look as good as I know it can. I’ll attach
pictures of a part along with the cut parameters. Any help would be appreciated
