Anyone have recommendations on what types of bits they use to engrave acrylic? Also feeds and speeds for those bits. I am needing a small point. Right now I am playing with some 30 degree with a 0.005 tip but am having issues with not cleaning out some of it. Looks like it is melting part back to it.
I used a ball nose that was a .125 inch. I think I had it set at 8,000 rpms at 100 inches per min. I told vcarve it was an engraveing bit at a .02 pressure.
@Edward_Bigham great looking product, rare to see a Yanmar outside a boat down here.
@Jamie_Wilson I do it with a ball nose too. 2mm on aluminum 700mm/m .075mm DOC. 5mm/m dive.
@Brandon_Satterfield that was my firsttractor. My big tractor is an Allis Chalmers. It’s a 1968 one seventy. Older than me.
@Edward_Bigham That looks great!
@Colin_Kaminski thank you sir. I try my best. I just love experimenting with the r7.
Thanks
