I am new to CNC, and very new to woodworking, and have been having newbie troubles for past few weeks.
Today I've tried cutting a piece of oak, and ended up with damaged work.
Here is the picture:
What puzzles me is that other side of the same piece ended up perfect, like this (sorry for the blur):
Area I was cutting was 20 x 20cm.
I am not sure if this (breakage and 'hairy edges') happened because of wood, or because of something else.
Any pointers that could help this newbie are much appreciated
Thanks.
