Cutting paper and card

[fenster]

Hi
I have only had my VLS3.50 50watt for a week and have been trying different materials I cannot find a setting that doesn't scorch the edge of the paper or card. Is this normal or is there a setting that won't do it? I have tried adjusting the intensity but this didn't work.

Also any ideas what would be the best setting to cut High Impact Polystyrene I have tried variations of acrylic and card but the edge seems to melt.

Any help greatly appreciated

Had this from someone here who uses them a bit:

I have tried cutter some paper on our 50W laser and there was no scorch marks.
I used ‘paper’ material with a thickness of 0.1mm – 0% override. VersaLaser control panel software version 5.26.
You could try reducing the airflow by adjusting the valve as described on p79 of the User-guide. ( this is a .pdf document located on the installation CD)
As regards HIPs, in our experience also we have found that it is not a suitable material to cut on the laser as it tends to melt too easily.

Hi,
I have a VLS3.50, 40Watt, and I send you some settings that work at me (power (%)/speed(%)/PPI):
- paper/cardboard 250g/mp - 60/80/1000. Increase speed if burn too much;
- acrylic transparent, 6mm - 2 passes: 1. 100/3/1000 and 2. 100/15/1000 and rise table with 1mm.

But.... hey: laser burn!
I make 2 years of tests on diferent materials .... and still do tests.
