I have been using the pcb-gcode with eagle which worked well but that 
board was 2 layers of copper minimum, and radio shacks copper was far 
from being even 1 oz so I had a heck of a time where I had to use 
thru-holes for an interconnect and parts were covering the thru-hole.  I 
have it working, as the spindle encoder on my cnc lathe, but it took the 
third board make to get it right.  Its very difficult to adjust part 
spaceing as it wants to match the grid whether the grid was visible or 
not, so I wound up carving new disks until I got the slots in the disk 
to make a 50%, 90 degree phase signal for use as a quadrature encoder. A 
2% error there is a huge amount of noise what I have since written a 
filter to average the last 4 edges.  So the P in a pid controller can be 
cranked up giving a much stiffer load vs speed for the spindle. But on 
spindle reversing when doing rigid tapping on the mill, that filter 
causes enough  error at the turn around point that the Z axis withdrawal 
is a couple thousandths out of registration with the fwd drive, so I 
need to rethink that a bit.  I can see it on the halscope, but its not 
yet broken a tap for me from that slight in-out miss-match.  The 
backlash compensation takes care of it on a steady run, but the 
miss-match is 0.0588235294117647059 of the spindles rotation before the 
Z, holding the tap, is reversed to follow the spindle's reverse backing 
out of the tapped hole.

This was in 1.99z.

I did read what docs I could find but could not make the make, make the 
pdf. Some dependency that wanted to pull in about a gigs worth of gnome, 
and I am running trinity, currently at R14.0.4.  Unlike gnome, it Just 
Works(TM). My wet ram at its age, 81, cannot recall exactly what that 
missing dependency was now. Heck, sometimes I can't remember what I had 
for breakfast. :)

Thanks & take care.
