Cutting Rowmark

[clockwork]

Hi all
Need to cut some of this for a model. Purchased the material from Trotec - website information about laser cutting this
suggests speed and power settings but also mentions PPI settings. (reference to 40 watt CO2 laser)
I seem to remember being told that there are some settings you 'change at your peril'. Would appreciate advice .......
Thanks in anticipation .....

Depends on the thickness, but I found 50/20 worked well on .75 if it is very fine work you will need to tweak the corner power
