Re: [Emc-users] gedit tools-external tools-new missing
On Saturday 06 September 2014 07:15:11 John Thornton did opine And Gene did reply: Gene, I've uploaded version 1.6 of Arc Buddy and used it to create a path from a print. I used the tools Arc Buddy way so it would insert the correct things for me. If you put a feed word in it prepends it to the G code. That doesn't show in the display although it is exported to gedit with it. Don't enter the leading F, I got two of them when I entered f10. You might change the prompt to say enter feed value. And it would still need to have the XY centerpoint entered after calculating it by hand by moving the centerpoint anchor to a phantom point that results in the start point being exactly where it is according to reading the DRO. For half circle turnarounds in the end of a groove, its fairly easy but it gets needs a sci calculator complex when the start and stop angles are not exactly on a 90 or 180 degree quadrant marker. I would find the geometric center of the arc angle entered, then go up that angle by the radius of the entered diameter, and adjust the center X,Y entered to change that point to the point just calculated, using a sin or cos of the angle times the radius, add those to the entered staring XY, then do the rest of the math. That way you can cut an arc for however many degrees you want that starts exactly where its at. For loops to cut to depth, output the present dro data entry as a restore move to cut the next pass deeper, before or after the g2/3 move. You might display this newly calculated center point found by this method as a mental error check to the user, but it will never need to be seen as a gcode entry. The only reason to save it would be for use as the reset move when incorporated into a loop to depth. Heck, if is a long slot that winds back up at the same point at the end of the loop, even that line of gcode is deletable gingerbread. Am I making any sense here?

[Emc-users] LinuxCNC 2.6.3 is released
Another month, another LinuxCNC bugfix release. This one's got some fixes for bugs that probably don't affect very many people. The most important ones are: * The XHC-HB04 jog pendant should work out of the box on Wheezy now. * External glade files should work better in gscreen and gmoccapy. (If you don't know what this means, it probably doesn't affect you!) Also several less impactful fixes, and documentation improvements (English and French). A new feature was added: the Axis GUI has a new (optional) .ini option that controls the default starting spindle speed: [DISPLAY]DEFAULT_SPINDLE_SPEED. Documentation for this new option is here: http://www.linuxcnc.org/docs/2.6/html/config/ini_config.html#sub:DISPLAY-section As always, my thanks go to the folks who tested and reported issues with earlier releases, and to the folks who worked to fix those issues.

Re: [Emc-users] Homing and restarting Lcnc problem
I tested for the hal_parport device or resource busy problem but was unable to reproduce it. I tested on a debian 7 system recently installed from the hybrid.iso. I tested at a master branch revision which describes as v2.6.3-659-gce43af0 (today's master branch) using a standalone test script in the file pp.hal loadrt hal_parport cfg=0 loadrt threads period1=100 loadrt not net x not.0.out = not.0.in parport.0.pin-01-out addf not.0 thread1 addf parport.0.write thread1 start which I ran multiple times in succession with halrun pp.hal I did not receive any errors in the terminal or in dmesg. On my system, the install parport_pc /bin/true line is commented out in /etc/modprobe.d/linuxcnc.conf, so hal_parport is working in cooperatin with the linux parallel port driver. My parallel port is on a PCI card. If you can, please test with the standalone hal script (modifying cfg= if necessary) to see whether that produces the problem for you. But the most basic explanation (that I completely botched the unregistration process for rtai when adding uspace) seems to be discounted at this point. Jeff -- Slashdot TV. Video for Nerds.

No, that has not been true for a long time now. Since version 2.4.0 (2010), linuxcnc has by default cooperated with the Linux parallel port drivers, so hal_parport and other parport-using drivers generally do not interfere with or experience interference from the kernel parport_pc driver. For that reason, systems installed since that time have the modprobe.d line that would disable parport_pc commented out by default. One great advantage of this, which we have probably not evangelized hard enough (or scrubbed away all documentation to the contrary), is the ability to refer to parports by their linux numbering, not worrying about I/O port addresses: loadrt hal_parport cfg=0 points at the system's default parallel port, if linux detected one. Super easy, and it even worked on my system where the only parport is a PCI-E one! Some people may still feel more comfortable with parport_pc not loaded. This reduces the risk that some linux software (such as the printing system) will touch the port, causing the attached CNC to do something unexpected. Those people can uncomment the line or take more drastic measures if they prefer. (best possible measure to take: a proper physical estop chain so this doesn't happen even when somebody boots windows 98 from cdrom or whatever crazy thing you might imagine) Jeff -- Slashdot TV.

Re: [Emc-users] Rifling machine
First off I don't want to start a shouting war of Tastes Great vrs Less Filling. As a (former) firearms manufacturer I researched barrel manufacturing methods in depth after being ask to reproduce a replacement barrel for a long since out of production item. The Hook and pull (sine method) was developed back in the black powder days when steel was soft and bores were large. Keep in mind that one reason a single groove is cut has to do with chips in the bore. The cutter often takes less than .0002 per pass. Early machines could easily be hand powered, albeit a long monotonous process. Because of the time factor Enfield actual made some barrels with only 2 grooves. As bores got smaller 6.5mm became about the smallest bore that could be produced reliably with current materials. During WWI material science improved. The cutter is often held straight in larger bores and all twist timing is done externally. Button rifling on the other hand relies on the angle of the flutes of the button to control twist rate. Button rifling is like a swaging operation because no cutting takes place. Broach rifling is like button rifling in that the twist is controlled by how the broach was ground, but the grooves are cut, not pressure formed. If this were attempted with LCNC I think it is an application which begs for absolute encoder support. Any loss of position while in process would likely destroy both work piece and the cutter and cutter carrier unless machine was dis-assembled to allow removal of work and cutter assy together so tool could be backed out by hand. The beauty of the original design is that short of taking a chuck key or wrench to the machine it is nearly impossible to get out of sync. Greg Bentzinger -- Slashdot TV. Video for Nerds.
