No ,you have not sent me the rotary axis version yet. I'd be delighted to
test it. I was over a friends house yesterday. He has a 4 axis CNC with a
rotary table. The software for the CNC ( maxnc) does linear moves on the A
axis. We figured out how to convert it to degrees. That sure would have been
nice to have the 4 th axis in degrees and why I know that the DR0 should
have that feature.
As Always, I'll get prompt feed back to you.

Subject: Re: [CAD_CAM_EDM_DRO] DRO boards
From: Tom Kulaga <tkulaga@...>
I have placed the order for a batch of Printed circuit boards for the -2/4
axis DRO boards. I should have them in 21 days. The quoted price per board
plus the $200 tooling charge makes each board cost ~$15-$16 each. Not bad.
It should make the assembly really easy.
In any case I have a list of those that have ordered boards. They will
have
first shot at them. Right now I have 35 boards on order which gives a few
spares.
Wow, 15-16 bucks for the board? That's pretty good. The encoder
chips from US Digital are only $23 each, the 74LS138's are less than
50 cents, as are the capacitors, and sockets aren't too expensive
from Jameco or Digikey... How much to get the connector
parts you're using? I know you said you changed from the ones that I
chose. Add in linear encoders and reader heads for around 50-60 bucks
per axis, and this is looking pretty economical. I had expected
around $50 for the PCB.
Tom Kulaga gets a free board for coming up with the concept, the
software and the schematic.
Hey, thanks! I guess this is a bribe to keep me updating it, huh? ;)
Speaking of which, did I send you the version with rotary table and
metric support? I don't have a four axis board here, so I was hoping
you could test it for me before I post it on the webpage.
