For the several months that I've had this VLS 3.60 (with air assist and 2.0 lens), when I cut acrylic there are distinct lines running vertical (or normal to the cut edge). They're spaced very close together, less than a millimeter apart.
I've played with dpi, power and speed, with little luck, and I'm looking to get some settings hints on how to reduce this effect if that's possible. I realize it may not be exactly the same for my machine as another, but just hoping to get some guidance. I'm usually cutting 1/8" but sometimes 1/4".
I just remember seeing the perfectly glass smooth acrylic shapes at the vendor's shop. They had said that specific example was cut on a different type of laser (can't remember the type), but that I should be able to get the same results from the VLS.
My other question was in regards to the slight angle on the acrylic (or any other material for that matter), is this minimized by focusing the laser to the top surface of the material. Would it be greatly reduced when cutting thicker (1/4-1/2") acrylic if I were to be using the high density focusing lens kit, as opposed to the 2.0. It seems to me this reduces the cone angle of the laser, just not sure how significant it is for cutting (I was told by VLS the HDFO isn't intended for cutting...).
Thanks for any light anyone can shed on this for me, it's not my main business so I haven't been able to devote a lot of time to testing out settings, but I'd like to be able to get a cleaner edge so I can make really professional looking signage.
