Hi Jeff I've read those instructions, but I think they are instructions about compiling EMC2; Do you mean that I can use the same method to compile EMC 1.0-39 on BDI 4.38? I will try that tomorrow...

Problems of compiling EMC on BDI 4.38
by 沈濛 16 Mar '06

16 Mar '06

Hello everyone... I am new to Linux and EMC, and I am trying to compile EMC on a BDI 4.38 but failed. I have read the Mailing list archives and use the 3rd option from Paul -- that is use the EMC 1.0-39. During the process, I first run "sudo apt-get update", and then "./ configure" seems to be completed successfully. When I run "make", the error message is: " ... make -C /lib/modules/2.6.12.6-rtai/build SUBDIRS=/home/surix/emc-1.0/ src CC=gcc-2.95 V=0 modules make: *** /lib/modules/2.6.12.6-rtai/build: No such file or directory. Stop. make: *** [modules] Error 2 " What is the problem? Please help me... Meng Shen

Question regarding compiling EMC BDI-4.38
by Mali Simon ITPSD2 16 Mar '06

Hello, Thank you all for helping me on my last question. I have made the compiling as you have recommended: cd emc2/src ./configure -enable-run-in-place Make Sudo make install Is it normal to take almost 2 hours to compile the complete package on Duron 700MHz? There were also a lot of warnings during compiling. When the compiling was finished I have made: scripts/emc and the emc2 responded: Can't find bWidget 1.7 package. There is a debian bwidget package; install it with sudo apt-get install bwidget. This was a problem for me because I have no means to connect my computer which linux is instaled on to internet. So I have copied the complete BWidged-1.7.0 directory to /usr/lib/. When I start (scripts/emc) at the beginning was no problem. But when I made the selection from the menu the output was: localhost:/usr/local/emc2/emc2-testing# scripts/emc EMC2 - TESTING-2006-03-02 Machine configuration directory is '/usr/local/emc2/emc2-testing/configs/stepper/' Machine configuration file is 'stepper_mm.ini' Starting emc... insmod: error inserting '/lib/modules/2.6.12.6-rtai/kernel/adeos/adeos.ko': -1 File exists insmod: error inserting '/lib/modules/2.6.12.6-rtai/rtai/rtai_hal.ko': -1 File exists insmod: error inserting '/lib/modules/2.6.12.6-rtai/rtai/rtai_up.ko': -1 File exists insmod: error inserting '/lib/modules/2.6.12.6-rtai/rtai/rtai_fifos.ko': -1 File exists insmod: error inserting '/lib/modules/2.6.12.6-rtai/rtai/rtai_shm.ko': -1 File exists insmod: error inserting '/lib/modules/2.6.12.6-rtai/rtai/rtai_sem.ko': -1 File exists insmod: error inserting '/lib/modules/2.6.12.6-rtai/rtai/rtai_math.ko': -1 File exists insmod: can't read '/usr/local/emc2/emc2-testing/rtlib/rtapi.ko': No such file or directory insmod: can't read '/usr/local/emc2/emc2-testing/rtlib/hal_lib.ko': No such file or directory ERROR: Could not load 'rtapi' ERROR: Could not load 'hal_lib' Realtime system did not load Shutting down and cleaning up EMC...

i just started using bdi 4.38, so I am reluctant switch to Ubuntu. I would like to get a little familiar with emc2, but I cannot build it. I am following some instructions on the wiki, but it is indicated these may be out of date. I am running as root and copied the errors from the terminal. Sorry for the length. It is what it is. I have no idea what to try next.

AXIS Development Updates
by Jeff Epler 10 Mar '06

10 Mar '06

General news: We rely on our users for feedback. If AXIS won't compile for you, doesn't work, or just acts in some quirky way you don't expect, let me know. My e-mail address is <jepler(a)unpythonic.net>. I also read these mailing lists. On an experimental basis, I'm providing read-only, anonymous CVS access to AXIS. The repository name to use is :pserver:[email protected]:2401/cvsroot and a typical first-time checkout procedure would look like export CVSROOT=:pserver:[email protected]:2401/cvsroot cvs login # hit enter at password prompt cvs -z9 co axis Important branch names are: HEAD: for ongoing development post-1.2 maint1_2: for the 1.2 and 1.2.x releases maint1_1: for the 1.1.x releases AXIS 1.1: There's a new point release of AXIS 1.1, called AXIS 1.1.3. Except for the version number and an emc2 build fix, it is identical to AXIS 1.1.3rc1. Except for another emc2 build fix, it is identical to AXIS 1.1.2. http://axis.unpy.net/index.cgi/downloads/01141952313 Barring the discovery of important new bugs, I don't anticipate any new releases from the 1.1 tree, especially since AXIS 1.2 will have a final release soon. In particular, if new incompatibilities with emc2 are introducd, they may go unfixed in AXIS 1.1. AXIS 1.1 is believed to work on emc1, bdi4emc, and emc2 HEAD and Testing systems. AXIS 1.2: AXIS 1.2 is still in the release candidate process. The latest version is 1.2rc3, released on March 6. I'm not aware of any significant bugs in 1.2rc3, and if there are no further code changes I intend to release 1.2 on March 20. Please send bug reports, translation updates, or new translations before then. http://axis.unpy.net/index.cgi/downloads/01141663025 AXIS 1.2 is believed to work on emc1, bdi4emc, and emc2 HEAD and Testing systems. AXIS 1.3: AXIS 1.3 is currently under development. New features that are now at least partially implemented include: * Support for 4-axis machines in the preview and backplots. * The emc2 "run-in-place" install doesn't install files outside the emc2 directory. For bdi4emc users, this means it is now possible to use emc2 and AXIS without overwriting any bdi-supplied files! * The colors of the preview and backplot can now be configured through the X Resources database. See rs274/options.py for the configurable items. * [DISPLAY]INCREMENTS can be used to select a different set of increments for jogging. Decimal and fractional values are supported, so that an imperial user can jog by "1/32" inch if he wants to. * Additional code has been added to try to make files that don't specify G20 or G21 still show a preview plot that reflects what emc will do. There is no set feature list or release schedule for AXIS 1.3. You can get snapshots of AXIS 1.3 (which will sometimes be badly broken): http://axis.unpy.net/index.cgi/downloads/nightly AXIS 1.3 is believed to work on emc1, bdi4emc, and emc2 HEAD and Testing systems. However, unless there is community interest, we may discontinue support for emc1. Jeff Epler <jepler(a)unpythonic.net>

Note: I previously sent this message to the emc-users list but was told this one was for BDI4 specific questions. The other list was for EMC2 issues. I'm currently running BDI 4.38 on a Pentium2-400Mhz PC. I recently installed a new 276oz-in stepper motor on my X-axis and trying to tune EMC for higher rapid speed. The fastest reliable speed I can get is 25IPM (500RPM, 20TPI leadscrew, 13333 pulse/second) with my 8microstep driver. Anymore than 30IPM, you can hear the stepper motor getting rough sounding (jitter??) and motor stops spinning. The period is set at 0.000007. I have tested it set at 0.000005 (any lower PC locks up and resets) but I still can't get any faster or more reliable pulse out of the parallel port. I played around with the P setting but just makes it worse if set over 1000. I currently set the MAX_VELOCITY = .41 (25IPM) since that seems to be the most reliable speed I can get for now. Anyone out there running a similiar speed PC and what is your fastest pulse output? 13,000 steps/sec seems rather slow to me. For comparison, I unplugged the parallel cable and hooked it up to my lowly pentium233 laptop running Turbocnc. I was able to get the same motor/driver to spin at 1200RPM with no problems. At 25IPM (500rpm) the motor sound so much smoother then EMC. Actually a little bit scary watching the table move back and forth at 60IPM since I only have 12" of X travel. I've been running bdi-2xx for the last 3 years or so and have just recently upgraded to 4.38 due to hard drive update. I also went through the archives and saw the reference to Quickstep. I'll do a apt-get and test it out however I do use backlash compensation on my mill.

lsattr/chown problem on bdi-4.30
by Gene Heskett 04 Mar '06

04 Mar '06

Greetings; I'm attempting to setup an rsync backup of the emc2 directory of this install but am running into permission problems. Having mounted the share with samba, I moved the password file rsync uses to /etc/rsync on the box, doing mkdirs as I went since the rsync dir didn't exist in the as installed state for bdi-4.30. I've also made a softlink from /etc/rc1.d/S50rsync to /etc/init.d/rsync and started the daemon. Now I'd like to run the backup as the user that normally runs emc since apparently root isn't to be trusted and rsync returns a no permission error when told to be root, but even as root, an lsattr returns only bad flag errors, and a chown returns a "no permissions" error to change the ownership of that password file. How do I get around this, I'm quite used to root being all powerfull on all my machines. -- Cheers, Gene People having trouble with vz bouncing email to me should add the word 'online' between the 'verizon', and the dot which bypasses vz's stupid bounce rules.

Question regarding compiling EMC BDI-4.38
by Mali Simon ITPSD2 02 Mar '06

02 Mar '06

I hope that you can help me with my problem regarding compiling EMC on BDI-4.38. When I use ./configure I get output: Can not compile realtime code for 2.6 series kernels. I use 2.6.12.6-rtai kernel. All configuration is originally from BDI-4.38 iso CDROM. What is to do to compile the complete package? Regards Simon Mali
