Only reason I brought this up , I made a small router pantograph from plans years ago, it required letter patterns scroll sawed out . Very tedious and limiting. It could only output 3 sizes of cuts mostly for sign making. After reading your post, I thought now I have 3d printers maybe I will take another shot at it . Unlimited fonts and the ability to scale the lettering would give more versatility to my rig.
I am really going to try and find an engraver like yours. She's beautiful.
Where's the fun in Cnc, hand work still rules. Cheers Mike.
