well.. EMC won't trap the slot smaller than tool error
nor can it do adaptive tool offsets (yet)
even simple things like a 'v' cut into a straight edge can lead to problems. old CNC controls (like a burney) will just radius from one edge to another. in the 'v' case this gouges a big chunk out of the material...I have seen this happen. That's why I ask...
best thing to do is grab a copy of BDI-Live and run some evaluations - It saves the hassle of doing an initial install.
* SpeedBump nods
If you find the code is usable (or adaptable) for your needs, the next release will have a bunch of stuff that might be of interest..
I'll look into it. Is there a design document somewhere outlining the structure of EMC2?
only the emc2_source_code_notes
in CVS somewhere?

does this channel log it's data? can I see the discussions from the sunday developer meetings somewhere?

That should keep you busy for a few hours...

good day gents...
* paul_c is away: Making chips
Need just a bit of boot advice.
* danfalck is away: going out to the shop...
dan...going shopping is always a good idea
eeeks... Not this time of year.
no paul...not that kind....to the shop...to the shop
good morning! sorry for ditching you the other day i had to leave to take care of somethings
hi mike...what are you doing these days
unix consulting, competing with sherline
going pretty well actually!
did you find that ISO ?
please don't put it on a public server - It's still under testing
-rw-r--r-- 1 root root 604M Dec 10 16:40 bdi-4.02.iso
sherline seems to think it is good for public use!
what is it based off of?
I need to add a post-config script and clean up a few things.
they have an open PO with me, I am just waiting for them to supply me with a disk image
The CD is Debian based, and running a 2.6.9 kernel.
you are crazy
how are the cherry chips
what is the advantage of running 2.6?
laying out the tool paths
RTAI development is concentrating on 2.6 kernels.
is the performance increase significant enough to justify the risk of an unstable kernel?
I think paul likes the bleeding edge
Is 2.6.9 any more unstable than the pre18 2.4 series ?
i don't know! asking you =)
to paul's horror I'm also going shopping
but every time i have worked with -latest linux kernel i have been very disapointed
i built a huge SQL server a few weeks ago
Been running a 2.6.9 kernel continously for the last month - No problems so far.
i had to buy redhat enterprise for $1500 because it was x86-64
Debian has 64 Bit packages in their repository.
hmm I need to use tool length compensation
does not seem to be well documented in the handbook
which is the tool file and what is the format?
ah...I see it...tool.tbl
just working on tool paths here
is segmotqueue working fine for you now?
no, sadly some more problems crept up
just have to run low accel
segmentqueue still stops cold every once in a while
beginning to sound like its terminal :(
works, but not reliable enough for production
if it cant be fixed in over a year, then perhaps its time to start afresh?
yes...the original author is on to other things...and just can't do a lot of free programming
I liked that 'segment assembly' mehtod I saw in another system ...
run down the path in the forwards directio, acceleratring out of the corners
turn it around and run backwards
well...just a plain old splining of the path would do
couple of iterations and you have the perfect path of little segments
with corner slowing
oops, tea time, back in ten
funny thing is emc does have cubic "subinterpolation"
ok...back to tool paths for me...and lunch
well I've always thought cnc packages needed a way to get a toolpath off a function
at least 2nd order polynomial and maybe a generalized function give the function axis, limits and watch it go
I'm still thinking 2D but....
* picnet Tips hat.
certainly didn't get much response off that suggestion did I. ;-)
