But, for manual milling, I still use the keyboard jog keys, as they give a constant feed rate, while the MPG gives a rate that depends on how smoothly you can turn the dial. I only have one jog dial, and an axis selector that allows me to control not only the axes but also the spindle speed override and feedrate override. (Just added these last two options.) Jon Jon, Or, you could do like I did, and add a joypad as well as the MPG. The joypad gives constant feed, and I can do it right at the machine, and still have the MPG for accuracy when I need it.

I also needed to edit xorg.conf to add monitor refresh rate and resolution. They have decent latency at 38000 nS (38 uS). and DVI. This was the first time I used a USB thumb drive to install Ubuntu. My CD was giving me fits, so i tried the thumb drive and it was flawless. I've had good luck with the ATI drivers, much more so than with NVidia. Their driver blob just sucks.

To: Enhanced Machine Controller (EMC) emc-users@lists.sourceforge.net Date: Thursday, March 8, 2012, 2:49 PM Dave, you have apoint there. I'm speaking now strictly as an amateur CNC user. Of course, making one or a couple of parts is much quicker manually than using CNC. But there are lots of parts you couldn't possibly make by hand, and this is where CNC comes in on the hobbyist level. Some examples: Imagine fabricating spheric hollow surfaces with a radius of, say, about 6 meters, in a 16 inch cast iron blank, with a precision in radius of about 1 mm. I needed these for mirror and lens grinding. How would you turn something like this on a purely manual lathe? Install a radius bar across the house? Another example: milling spur or other gears. I tried to make a single odd gear for my change gear set on its own machine. I have a wonderful little high precision dividing head. I had to turn the crank wheel some odd numbers of some degrees and umpteen minutes after each cut, and after the tenth I made a minute error so the blank was lost. Then I decided to set up a CNC system first, and soon made drawers full of perfect gears in short time. I repeated this on the large mill to make change gears in modulus 2 for my large lathe too. There would have been no way to do this, especially not in reasonable time, without digital control. A third example: I was making printed circuit boards for the stepper units of the 3 axis minimill I am building. I made the boards with eagle, etched them and had them drilled within about a minute. 3 times 300 holes would take a long time positioning and drilling by hand You don't have to be a professional to profitably use a CNC system, and I'm glad there is something like LinuxCNC or EMC2, as you like.

Probably You saw it mentioned in other discussion, where I posted it, but did You read it? I had a link in there that explains Your next question. the task manager of winxp has a process priority setting, with one of the choices being 'realtime'. never tried it for anything. but the realtime mode of operation in linux is still a general hardware timeshare approach, no? No. ..including stuff like keyboard and mouse. Definitely no. I would like to ask someone more knowledgable to explain it more precisely, but the main principle is that with RTAI kernel the tasks are separated - realtime tasks and all the other tasks. Keyboard and mouse are not on realtime, screen output also is not. Also LinuxCNC itself is separated between realtime and non-realtime, like it is shown here: http://linuxcnc.org/images/stories/EMC_Control_LG.gif In theory, if machine runs short on computing power, the mouse and keyboard might stop responding, screen might freeze, but machine will keep on running the motion precisely. And the whole difference from Your examples is that LinuxCNC follows, if it is keeping up to be realtime or if it is falling behind. I seriously doubt that windoze is measuring and checking, if it really meets the requirement for realtime. If LinuxCNC is falling behind, it displays error on the screen about RTAPI error occured, run Latency test. INI file specifies the length of base thread and servo thread in nanoseconds. And each thread is ran again and again in repetition, so what LinuxCNC does is it takes the actual time, taken to execute the thread last time, and compares it with the specified number in INI file. If the actual time exceeds the requested time, then it triggers the error - machine continues working, but user is alerted that there was an realtime interrupt. Usually the solution is increasing the thread period (especially true for base thread). There is a Latency test application, which runs those 2 threads and measures the timings and shows the maximum deviation in absolute numbers (nanoseconds). And there is one very very nice feature of Linux realtime kernel, which I am sure is not available in windows: isolating CPUs for realtime There is a boot-time parameter isolcpus that allows user to isolate certain cores of CPU exclusively to realtime tasks. That is one more thing why I like D510-series ITX boards - it has dualcore Atom CPU and I usually isolate one core to realtime. Reports from other users show that it considerably improves the board's realtime performance (which is good also without this). 2012/3/8 charles green xxzzb...@yahoo.com: no, i was talking about commercial production machining centers, mostly fanuc based, 15-30yr old vintages.

As for this problem, from the clues I'm picking up here, if a global variable is created/adjusted inside of an onumber while, its gone when the corresponding onumber endwhile is finished. That is the only conclusion I can come to that fits the observed results. IMO, if its defined globally, as in #_name, even if its inside a while/endwhile then it s/b globally usable. Such seems not to be the case. So it seems to be at odds with the docs in this regard. Fixing that, could even fix the exit crashing I'm getting maybe? As in a screwed up stack? Cheers, Gene Gene, How are you returning the value of the global variable after you exit the loop? Perhaps you need an assignment statement prior to the exit of the loop to ensure you are returning the value you want? Crazy things can happen inside those things to global variables. mark I had been assuming that it was whatever it was inside the loop, when the loop fell through. That didn't turn out to be overly reliable as it was often the same value as before the loop, even if it had been modified 360k times inside the loop.

Without a functioning driver, Windows 2000 won't admit your pickit exists even if the port itself is electrically sound. Your smart drive test was necessary but not sufficient. It exercises a different driver. Were I in your shoes, I'd install MPLAB X IDE in Linux and drive on rather than arm-wrestle with W2K. To paraphrase what Admiral Farragut never exactly said, Damn the bugs, full speed ahead. Regards, Kent Hi Kent: Thanks for the note. I am aware of the age of Windows 2000 as I used it in my business of computer animation in S. W. Florida. That was up to 2005 before I retired. I agree it is a pain but sense I am retired and this is a hobby, I used what I had on hand, as MPLAB listed the system software could be Windows 2000 or XP. Hi, Bill. My wife and I are retired as well and fully understand the financial constraints. We choose to forgo many technology baubles in order to spend more in other pursuits, like staying involved in our grandkids' lives. My wife, for example, is still using a Sony laptop we bought when she was consulting a decade ago. She likes the full keyboard so much she doesn't want to buy a new laptop. We're running Windows 2000 on it because that's the latest version that has working drivers for it. I put that Query on this web site about two weeks ago, asking if there was a complier that would work for programming the dspic's, under Linux. One of the fellows said that there was a compiler but it was a pain to get all the files, in place, that was needed to use it under Linux.. Being the novice that I am, not being a programmer, I thought it would be more of a challenge than I could overcome with my limited knowledge. However, I think I will give it a try as I like the Linux operating system much better that Windows. It reminds me of the Amiga operating system that I use to use for model building, ray tracing, and animation recording. Oh, man, a Amiga user. You really were serious about animation work. I never had one but I drooled over the one my friend (also in video and animation work) had. I have neither the eye nor the temperament for graphics work. I envy those who do. If I need some direction, are you willing to lend a bit of help once in a while? I and the rest of the LinuxCNC crowd are always available to kibitz. Collectively, we know everything (and if it turns out we don't we can still sympathize with you!). What direction did you decide to go---MPLAB or MPLAB X? And in Linux directly or in Windows running as a virtual host in Linux? Of course, inquiring minds also want to know what you have in mind for those dspics. Bill Good luck. Regards, Kent Hi Kent: Yes we are all for the grand kids too! Well I think I will go with Linux. The MPLAB I have just downloaded was 8.80. I purchased the Pickit 2 debug. The project is a brushed servo controller. Knowing me I think it will go beyond that, maybe BLDC. Then who knows what. Well Kent back in 1985 my wife and I opened an Amiga store in Florida. Because I used it for 3 D wire frame modeling, in my Architectural Illustration business. I thought it would really catch on. She and I went to Commodore's repair school so we could support the machine. We were authorized Video Toaster retaillers. Opened a larger store in a strip shopping center about 1989. I ran both businesses from that location. About the time we got rolling the Hi-way dept. started tearing up the main hi-way that went in front of our center. And the first war started. Mail order got going real strong and we were doomed. I could buy Commodore Hi-res monitors from mail order cheaper than I could buy from Commadore direct and we were authorized retailers with them. I hate loop holes!! It was a great machine, 1 main processor and 5 sub-processors. Multitasking for real and all on 512K ram. I networked the Amiga, with the Windows NT4.0, and the MAC Quadra 950, for all animation and video

APICs were added to CPUs and their chipsets back in the early 2000's I believe. If you don't have one on your CPU/motherboard then obviously the software cannot use it - hence the NOAPIC option.

Re: [Emc-users] State of Wizards/Druids for simple machining.
Yup. I'm here. It's been a while since I touched GWiz -- or EMC ^H^H^H^H LinuxCNC, for that matter. I've been thinking about a slightly different model for manual (or perhaps I should call it interactive) machining. Imagine: 0 -- select a tool from a menu (also feed rate, etc -- or possibly material) 1 -- select a wizard -- rectangular surface, pocket, bolt hole, or whatever 2 -- follow directions (for rectangular surface): 3 -- move the tool to the upper left corner (using jog, mpg, keyboard, whatever). 4 -- push the select button on the screen, panel, mpg... 5,6 -- now do the same thing for the lower right corner 7 -- now select a stepover 8 -- hit go... The machine then just does what you told it to do. I think this would be pretty straightforward using the existing subroutine capabilities, mdi interface, etc. Ken On 3/8/2012 2:56 PM, gene heskett wrote: On Thursday, March 08, 2012 02:53:49 PM Frank Tkalcevic did opine: Don't forget GWiz (http://wiki.linuxcnc.org/cgi-bin/wiki.pl?GWiz_-_A_Gcode_Wizard_Framewor k) - it needs a screen shot - that page doesn't sell it well.

Re: [Emc-users] ubuntu 10.04 + emc cd from the emc build problem
You must be thinking that the ISO is bad, but the CD that just failed on me while installing 10.04.04 was burned with the same ISO that I used to create the USB stick drive that just installed the software.. (?) I have about a 50-50 hit rate with installs off CDs and I have no idea why. It could just be my luck (I don't buy lottery tickets for the same reason) or ? ;-) Dave On 3/9/2012 11:42 PM, gene heskett wrote: On Friday, March 09, 2012 11:36:06 PM Dave did opine: I thought you probably still had the LinuxCNC live CD image sitting on your hard drive someplace.
