Re: 5-axis machine controller

Hi Marc
the cvs stuff is easy to use... attached is a step by step description of
what I had to do to download the cvs code and to get it to build. You may
find some differences now as the version I pull down was about 6 weeks ago.
Hope this helps

# The Saga of Getting the EMC/RCSLIB CVS Code to Build and Run.
#
# At this point you should have installed Redhat 6.2 and 
# patched a 2.2.14 virgin kernel with rtlinux_2_2a.
#
# some stats on system (P133/64mb and 3gb of scsi 2 drives)
# if you open this file in an editor, you can cut and paste the commands
# into a terminal window as required... or turn this into a script

[root-at-cnc src]# uname -a

# create directories for emc/rcslib project

# now try the builds
# see comment below...[root-at-cnc nist]# ./install
# 14 minutes to failure
# I could not get rcslib to build. I kept getting the following msg:
#   In file included from rcsvers.cc:3:
#   rcs_defs.hh:295: dbg_mem.h: No such file or directory
# to fix this, I had to edit /usr/local/nist/rcslib/src/rcs_defs.hh line 294  
# and comment out as shown below or delete the line 
#  //#include "dbg_mem.h"            // DEBUG_MALLOC, DEBUG_FREE
# 

[root-at-cnc nist]# ./install
# rcslib takes about 14 minutes to build on my P133
# emc takes about another 16 minutes to build, a few warnings in dcmotor2.c
# nothing fatal
# you need to answer y to the 2 questions asked.

# now try the demo
[root-at-cnc nist]# cd emc
[root-at-cnc emc]# ./rs274ngc_new_sim.run
# click on ESTOP/Estop Off, Estop OFF/ Machine on, Manual/Auto
# click on Open.../cds.ngc/Open
# click on View/Backplot
# finally... click on run and watch the gcode roll....

# the above process takes a little over 1/2 hour... It took me 2 weeks
# to figure how to due this and to get it all to work... To bad I can't
# bill by the hour :}
