I am trying to CNC cut ¼ in carbon steel, however I can't find the correct settings in XCS, when I emailed Xtools support they said that it can't cut past 5mm.

However, the website says it can cut up to 10mm carbon steel…

 I am very confused but have been tweaking the settings so much but still haven't found anything that has cut well, has anyone had any luck tuning XCS to cut ¼ in carbon steel? 

My current cutting settings are:

Power and duty cycle: 100% 

Speed: 15mm/s 

Nozzle: Double layer nozzle 

Gas: 12psi of pure O2.

Cutting frequency: 3000hz

perforating duration: 700ms

Perforation duty cycle: 60%

Perforation frequency: 1500hz

 

Any help would be very appreciated!! Thank you!
