Re: [Emc-users] rapid prototype
Hi Jeshua, for me use a regular CNC mill for rapid prototype makes more sense. major challenge is the head that will introduce hot plastic. i think that small shop or business can start manufacture such heads or wait until Made in China will be ready. i found that reprap city based and not country based like EMC2 and result of that there is not enough people in each city that have good experience. is there proven design for head? design of head in reprap too simplify as i can see. thanks aram interesting if anyone used EMC to build rapid prototype machine. it should be 4 axis machine. 3 axis X Y Z and 4th axis head that injects liquid wax -plastic. Hi Aram, There has been some discussion on this list recently converting mills to 3D plastic printers using EMC, see these threads: [Emc-users] Status of Linux-emc and 3d printing?

[Emc-users] Usefulness - was Re: OT: 3D Printer Mods? [Emc-users] OT: 3D Printer Mods? [Emc-users] 3D Printer Mods? I would like to see a wax printer as well, but people have reported successfully performing a lost-plastic process with both ABS and PLA plastic. The process is the same as doing lost wax, but you burn out the plastic instead of wax. From what I read the PLA is safer/more pleasant to burn out (smells like maple syrup I read) but the ABS burned out cleaner. I am sure with some experimentation you could get great results from both. That is what I primarily plan to do with a 3D printer and/or conversion when I get around to it.

Re: [Emc-users] The screw works!
On Tuesday 24 July 2012 06:30:42 mark center did opine: I use 0 to 5 degree rake and 2 to 3 degrees absolute flank clearance. The compound angle, viewed orthogonal to side view, is about 10 to 15 degrees. The spiral effect (lead angle) causes entering side to be more acute than exit. Nothing is really terribly critical as long as a cutting flank does not rub against either side of the thread flank. Ridiculously acute appearing tool angles will cause less problems than angles that would appear correct for turning, they just wear faster. You might only be able to thread ten or fifteen parts before you need to resharpen. The lead angle is a function of lead, diameter, and whether internal/external. Rather than make a jig, since I didn't really know what I was doing yet, I just tipped my vise up 60 degrees and clamped it into the vice at about 15 degrees to the left on the right side of it, with a 1.5 dremel diamond wheel and arbor in a drill chuck in the spindle, turning about 2000 revs. That took me about an hours worth of sweeping it back and forth, lowering the z about a thou per pass to get rid of the belly and bring the shine all the way to the edge, and when I did, I found it was sensitive to the wheels direction of rotation, leaving a shiny line at the cutting edge that would not wipe or blow away if the wheel was turning to approach the edge, but which was almost instantly removed if I reversed the spindle so the diamond was traveling upwards toward the edge. Then I turned it over but set the left face at about 20 degrees, (pitch angle SWAG) which again started polishing the lower side first, and I've lowered z an additional 20 thou since. When I gave up well after dark last night, with about 30 thou to go to get it up to the cutting edge, meaning another 3 to 6 thou down at the spindle. Apparently my attempts to sharpen by hand had left it effectively with zero heel clearance on the left, cutting edge. Quite a belly on the side I am having to remove. Because the threads I was cutting are relatively fine pitched, I haven't tried to form a round nose on the tool other than making a just visible shiny spot on the end, not more than a couple thou wide with a hard arkansas stone. The first thread I cut with it was beautiful, the last were pretty rough feeling but worked. I have a parting tool that I have threaded several times on a manual South Bend Big 10 (and now a Monarch 10EE) I've not considered buying an insertable tool yet, most of the tool shanks are too big for this machine, and the inserts are sold by the karat. But it would be nice if there was a side of the tool clamp for the cutoff tool, most holders offer little or no sideways deflection restraint, with this a2z's wedge style clamp being particularly non-impressive in that regard. More bad weather today, it was 76 at 6 AM, with severe afternoon thunderstorms predicted. The only advantage of the heat to me is a lighter weight sock to keep my diabetic feet from feeling like they are freezing. I hope it doesn't replay 3 weeks ago, there are still some folks in WV without power. And the state P.U.C. is all over the electrical folks because of it. Thank you Mark.

From what I've seen looking into USB 2.0 device programming, the transfers are too quick for most (maybe all) microcontrollers to keep up with in software, so you are generally tied to DMA transfers on the microcontroller side. FTDI has some chips that eliminate the DMA issue for the programmer, but they may do DMA internally. There is a mode called 'isosynchronus' where a peripheral negotiates a certain amount of transfer for every time USB transfers data. This mode can be used for more reliable data streams. I suspect that a high bandwidth peripheral that has a USB port all to itself will not be as problematic as one that contends with a mouse and keyboard for the port. I also suspect that the USB connection has a certain period between communication events. A base period that gets lots of real time errors from contention with USB*/may/* have much less problems with both faster and slower base periods. Perhaps when documenting what works, and what doesn't, it would make sense to keep track of: 1:USB 1.1 or USB 2.0 2:What is the device? 3:Does it have the port to itself? 4:Is a hub being used? A hub may complicate the timing. 5:The appropriate part of the log files. -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Dear sir, when i excute wish8.5 , it'll show the information wish8.5[5112]:segfault at 0 ip(null) sp bfc67b60 error 4 in wish8.5[8048000+1000] Segmentation fault. i have installed tk8.5/tcl8.5 in a Development Machine ,then i copy wish8.5 and the lib it needs to my target machine . my target machine is a i486 architecture with the linux kernel is 2.6.32 + rtai3.8 which is the same with my Development Machine . the wish8.5 can be excuted in my development machine ,but to my target machine ,it shows wish8.5[5112]:segfault at 0 ip(null) sp bfc67b60 error 4 in wish8.5[8048000+1000] Segmentation fault. i don't know the reason. yours liangrunhan -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Re: [Emc-users] BASE_PERIOD and Intel D525MW boards
Gene (and, others) I assume you also have the option set in the kernel line of your grub.conf (or menu.lst, depending on the mood of the distro divided by the phase of the moon) isolcpus=1, Yes - e.g., top shows 1 processor. When running a Gcode program, it's averaging 68% idle. Hyperthreading is off in BIOS, as is audio, ethernet, and serial port. I do have in the machine: 2nd PCI serial port; for cnc4pc mpg; touch probe code in the HAL file (cnc4pc touch probe) I did bring the BASE_PERIOD down from 30,000 to 28,000; last time a real time error came up was when moving the USB mouse over the linuxcnc window border. Poof! up comes the real time error message. I guess I'll just live with it; it does take about 10 minutes for it to show up, so it's not too bad (I guess??)

I got a G540 so I switched over the 5i25 firmware to the G540x2. Was there an XML file for use with pncconf? I did some searching and couldn't come up with anything. I had used the prob_rfx2 xml with the BOB I had previously. Thanks Bryce I have not made a XML file for this yet... I thought it had a charge pump component, which PNCconf doesn't know about but I can not see that in the PIN file, so I should be able to build one the PNCconf can already use... I'll see if I have time tonight. Chris M The latest G540 configuration uses a one output stepgen for the chargepump due to that rather annoying G540 feature that the chargepump needs a 10 KHz frequency which would force the use of a base thread if the bit was just GPIO (dont know why 500 Hz would not have done, oh well) The chargepump stepgens are at the end numerically so dont interfere with the G540s stepgen assignment (they are stepgen 8 (P3) and 9 (P2)) There are a couple ways to get a square wave out of the stepgen. One is to set the position scale to 1, set stepgen output mode to quadrature and operating mode to velocity and finally set the velocity to .25 (this is .25 instead of 1 because quadrature mode counts 4x as fast at step/dir mode) -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
