Hi,
Im getting myself a cheap chinese cnc engraver, 3 axis.
Im wanting to engrave on 38mm round aluminium, the letters will be around 6mm heigh and two lines of words. What software will allow the cutter to adjust its height to follow the curve? no need to go to 4th axis as im not writing all around the pipe..

Im new to cnc so dont want something to complex.

Thanks
Darren
