[Emc-developers] Rockhopper revisited
Greetings Guys; Someone mentioned that rockhopper can make .pdf s somehow, and those of coarse can be scaled. Since I now own an HL3170CDW color laser printer, what steps does it take to do this, blowing my lathe .hal file up into at least a 6 page output? Progress on the lathe, it seems I bought a dud controller on ebay, blown in a manner similar to what I did with the first one. So rather than pour more money down that rat hole, I've ordered one that uses HEXFET's, good for 25 amps, runs dead silent. Nominally $150, some outfit in Wisconsin makes it. And I've located the rest of the chips to shotgun the C41, so maybe I'll be turning the spindle motor again by Monday evening. Thanks for any help on rockhopper.

Re: [Emc-developers] exploring the LinuxCNC 'burden' on my BeagleBone Black
Hi Kent, I was your dev list post and noticed that your blog link says that you're running the starter kit from Michael on a BBB and that it's a 3.8 kernel with Xenomai etc. I was about to build a 3.8 for the BBB etc, but decided to ask Michael where to find whatever he's already built. He responded that there would not be a 3.8 for a couple of weeks - so I'm confused. Can you point me to the source of the software load referenced in your blog? Dave On 6/6/2013 12:19 PM, Kent A.

It's interesting that ssh for the X forwarding is a big chunk of your CPU utilization. Have you tried switching ssh form the default 3des cipher to blowfish? It's much faster. There's more to come in the details that I haven't posted yet. Despite blowfish and arcfour both being faster---it must be true, I read it on the Internet---they don't substantially aid here. The issue may be clouded by the ARM chip which I suspect isn't tweaked the way many x86 chips are, and the algorithms in the OpenSSH routines, which I suspect may have been tweaked for x86. There were differences to be sure, just no home runs. The ciphers I forced my SSH client to select using the -c option were -c (default) aes128-ctr -c arcfour256 -c arcfour128 -c arcfour -c blowfish-cbc I also ran throughput tests between the hosts, using 'dd' to generate very large files of zeros in memory (to avoid benchmarking the file system) on the BBB and piping them through ssh to one of the x86 hosts. Haven't had time to post the numbers. I did not see any significant advantage to using compression (-C option), either. That's a technique often used in WAN communcations, whereas my hosts are communicating over a single LAN segment. Regards, Kent -- How ServiceNow helps IT people transform IT departments: 1.

Re: [Emc-developers] Rockhopper revisited
On Thursday 06 June 2013 18:55:24 EBo did opine: rockhopper? Yeah EBo, it draws logic diagrams of what you have wired up in your .hal files. But my lathe has so much stuff, that by the time I load its generated output into inkscape, and zoom in to where I can actually read the box titles, is about 2 feet high pushing 6 feet wide, so if I want to print it, I need to run it thru a poster maker, tiling the image onto about 15 sheets in landscape mode. With that, I hope to see what I may have thats dead ended and can be removed, easing lcnc's workload in the servo-thread.

This is my first situation where its performance became an issue. For those who want to run in what I called naked X11 mode, there's a bit of magic needed if you are running your XServer on Ubuntu. Not only do you need to allow it to accept X connections, typically by invoking 'xhost XClient hostname/IP' or 'xhost +' if you are lazy, but you also have to set it to allow connection via TCP. Ubuntu (well, actually Gnome) makes this unaccountably hard in its attempt to do everything for you. The traditional setting in /etc/X11/xinit/xserverrc is overruled by a setting in gdm.schemas. You can prove this by changing xserverrc to allow TCP (eg., delete '-nolisten tcp' from the invocation) and restart gdm. Run 'ps ax' and note that X started with the 'nolisten tcp' option despite you just told it not to. In Ubuntu 10.04LTS, at least, this tweak works: In /etc/gdm/gdm.schemas, change 'true' to 'false' in the following stanza schema keysecurity/DisallowTCP/key signatureb/signature defaultfalse/default --- here I've already changed 'true' to 'false' /schema Save and restart gdm using, for example, 'sudo service gdm restart'. also interesting to note - the core parts (milltask and the interpreter embedded therein, plus rtapi_app and usercomps) use negligable CPU compared to GUIs For all my runs with the AXIS GUI, milltask was number two on the hit parade, consuming roughly 28 percent of CPU time and 3.1 percent of memory. With the other GUIs it was always less than 5 percent of CPU, more typically 2-3 percent, as were hal_manualtoolc and halui across the board. I looked at every task down to 'top' which always consumed about 1 percent of CPU and 0.3 percent of memory. I was tired and only took the time in this first cut to report on the two that most concerned me. Details later, maybe. Regards, Kent * you can't work with computers at NIST for three decades and not be such. We wore belts and suspenders, so to speak. Public perception was a huge issue. By act of Congress, NIST plays a major role in computer security research, testing, and standards in the US, culminating in the Federal Information Processing Standards (FIPS). It just would not do for any of us to be caught with our own pants down...and don't think the Internet blackhats don't try. Our firewalls were/are under constant assault and we were constantly lecturing our staff about social engineering practices. Sometimes dumb luck carries the day. We were one of the few major sites to sidestep the infamous Morris worm back in 1988 but only because our principal mail server was running on VAX/VMS and not Unix. Sometimes not everyone gets the memo. Sometime in the 90s, we got hit right between the eyes by a vulnerability in Sun Solaris because we had Suns running on an experimental ATM (asynchronous transfer mode, not a cash machine) network connecting us by optical fiber to several universities. The ATM network bypassed the firewall. The Suns involved were all supposed to be in a DMZ, but dualhoming with the regular network was not unheard of. Naturally, security audits got more draconian.

Cheers, Gene Gene, fwiw try pdfposter or posterazor or poster or scribus Reading the descriptions, I installed scribus. It can blow it up ok, but when I asked for a printout, what would fit n one page at the size I had zoomed was all the printer gave me. Next, I'll see if poster can deal with an svg file for input. I did hit the posterazor site, but it mentions a trial period and never did tell me how much. And pdfposter would need the thing made into a pdf to start with. Possibly something can be worked out. I was hoping there was a plugin for scibus, but if there is, its not in the buntu repo. all available from synaptic i may have lots of repositories enabled but one of those oughtta be availble to you all of the print huge posters on std letter paper ready to be taped together i dont print stuff anymore , but when i worked on big hal diagrams i used similar tools and taped the sheets together yes, a big problem with such diagrams is size and scale when its small enough to overview you cant see the problem point when you can see the problem point you cant see the overview maybe some of the newer 'lensing' code may help ( fisheye zooms a bit, leaving the overall view as well ) btw svg is zoomable/panable so maybe you could use a good svg viewer rather than a pc of paper. up to you. also organizing hal work in 'sheets', hierarchically, like old orcad, helps regards tomp -- How ServiceNow helps IT people transform IT departments: 1.

I saved the image and looked inside. Right after the DOCTYPE declaration appears the information line !-- Generated by Graphviz version 2.20.2 (Tue Mar #160;2 21:46:26 UTC 2010) For user: (kreed) Kent Reed,,, -- !-- Title: HAL Diagram Pages: 1 -- svg width=1810pt height=2159pt viewBox=0.00 0.00 1810.00 2159.00 xmlns=http://www.w3.org/2000/svg; xmlns:xlink=http://www.w3.org/1999/xlink Great. Graphviz graciously tells us what it thinks the image size should be (SVG is scalable vector graphics and doesn't care). You'll have to figure out the size of the printable area on your printer. Let's say its 8.25 X 10.75 (laugh if you must, you A4 bigots! It doesn't get any prettier converting millimeters to points). At 72pt per inch, that's 594pt X 774pt so the image size is roughly 3 sheets X 3 sheets. You can use the ImageMagick suite (available through the Synaptic Package Manager) to create a bunch of image files of the right size out of the original SVG image: convert -crop 594x774 halgraph.svg halgraph-%d.png Hmmm. I get 12 images, not 9. Oh, wait, my roughly overlooked the fact that the image is slightly wider than 3 sheets. Anyway, there's your letter sheet-sized images. I tried to create the images in pdf directly using convert but I got abnormally wide output images. Similarly, I got strange results converting the png files to pdf using convert. You could futz around some more to get good pdf conversion or you can just print the png files directly from the Gnome Image Viewer or whatever you're using. As a matter of curiousity, what is the width and height information in your halgraph.svg file? I suppose if it's big enough, convert could choke.
