Hi Andy,
The version of my EMC2 is 2.4.3. I do not whether the problem has been
fixed on this version or not.

So I now have my machine up and running on EMC (Wahoo) but I am running into a
machining issue.
The issue comes up when machining a 3D part. see photo:

The star is cut using an 1/8 ball end mill. The cutter goes to a depth of .25
inch and then fol

Just in case anyone else wants more changer information:

The problem with this is an enormous amount of room and capital required.
Plus, this is just not my style -- though I respect the fact that other
people may make other choices.

Andy, Kirk, Chris, Kyle,
Thanks for the replies and info. Combining my response into one post to

The relay contacts are coming into a Mesa 7i37 board. My concern is both

Are you talk
What is the sequence of messages sent and received to an FPGA parallel
port servo card at each servo interval? I looked on the wiki and
couldn't find this information. What all goes on when controlling 3
servos over the parallel port?

My guess is that it is not worth $20k. At best it would be worth $14k or so.
Lots of dreamers on ebay asking for a pie in the sky.
I have never been like that and I despise this approach to business.
That said, if i can fix it in a few hours and by throwing some minimal money
at it, I will try.
yep, something like that.

I would bet that this machine has non generic software on it
specifically designed to make it easy for people to grind cutters and
tools.
If you put a generic CNC control on it you will have none of that,
making the machine much harder, maybe impossible to sell.
