If I knew anything about the interp, I'd be half tempted to try to implement G90.1/G91.1 (abs/relative I&J for arcs)
it would be a good first project
add them to _gees in interp_array.cc
what the heck, might as well give it a shot
handle them in convert_distance_mode (set a new flag in "settings")
they'll become a modal group, right
well first, how do you want them to work?
can you have g91 and g90.1 both in effect?
or can you only have one of the four?
if the former, new group - latter, same group as g90/g91

I was originally thinking of them as a distinct pair
no smoke yet.
what are we testing?

cool, I can't look at it now I'm downloading open office for windoz's on dial up :)
dial up? what is that? ;)
it connects to the string that goes out to the highway and there is a tin can on the other end
and most of the time the string is broken
no it is reliable but slow
I can get high speed if I install a 75' tower to see the antenna

no I'm down in a valley on a dead end dirt road off of a dirt road...
with cutter compensation in effect, some dwell will occur for blocks that are executed in less than .25 seconds. colinear moves cannot be programmed.
M codes cannot be used until the block after cutter compensation is turned off.
Z axis moves will not be compensated.
(I don't know what that means)
Z motion must not be programmed in either the first or last three compensated blocks.
Multiple Z moves must be separated by at least two blocks of XY data.
most of these are design compromises - but the colinear thing seems like a 'documented bug'
EMC: 03jmkasunich 07TRUNK * 10emc2/src/emc/rs274ngc/ (7 files): initial work on G90.1/G91.1 - so far all it does is parse the g-codes and sets an internal variable

hi.. i need a bit answer on:
acording im reading on HOSTMOT2.c, PC communication behave on Mesa is based on 3 Major variable:
"Encoder", "StepGen", "PWMGen" ... and PID calc being done on PC, based on encoder information, is my perception Correct?
mesa do the counting and send the value of pos to pc
if u dont mind, please explain anything on this, to enrich my knowledge(or curious)... any commment would be very usefull for me
|_____|``|_____| ''=is the length of PWM and stepgen is how much |``| pulse being generate
cos i must disconnect my internet connection about couple minute from now... thats above is my homework
alex_joni: did we do the 2.2.7 yet?
I hope to get word back from max about the stg fix on TRUNK
if he tests it and it's ok, I'd definately want to stick it in 2.2.x
ok, just wondering
but it's probably not that important to hold off 2.2.7
what is stg?
I think it was one of the first (if not the very first) hardware that worked with emc1
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emcdevel/2008-11-09.txt
hi all, would fanuc,siemens etc operator & machine manuals be of any use as reference material? if so im happy to donate some copys your way
paper or electronic?
electronic would be more convenient, but probably would run afoul of copyright if we posted them somewhere, or made copies for every emc developer
paper would avoid that, but murphy says the guy who has them isn't the guy who needs to refer to them
i have siemens in electronic, as downloaded that from there website,
also have a fadal one also on CD,
we need to follow copyright
is the seimens website open to anybody? if so, let us know the URL, we can put it on our wiki or somewhere, and if we need to look at the manual we can go there
if the website is only open to seimens customers, etc, then things are more complicated
SWPadnos (but not exclusively): http://www.xtratum.org/
that is _really_ interesting to watch during the following period
it seems RTLinux/GPL is evolving into XtratuM which is both a layer ontop of a regular linux (like the old RTLinux patching), but also a system designed for embedded archs (if I read it properly)
seems it's similar to ADEOS in some aspects
ok jmkasunich ill add the seimens link onto wiki some where ill have to dig it out my bookmarks for ya, if there ever anything u need looking up just let me know ill be than willing to help out any way i can
