I am an 80 year old newbie and don't know anything about wood.  Need cut and engrave tests for 6 mm MDF.  It is listed but no tests.  What would be the closest wood in XTool Material Library that I can try?  Also, if I learn how to create my own and save it as 6 mm MDF, will it show on the Material Library? I have an S1 40W.

Thanks,
