Re: [Emc-users] Emc-users Digest, Vol 96, Issue 51
Detailed question. I want to implement these as wizards. I see there is already work done here (http://linuxcnc.org/index.php/english/forum/40-subroutines-and-ngcgui/11414 -metric-lathe-subroutines-g71-g72-etc-etc) so I'll probably borrow from that. Feel free to borrow away ( I wrote them ) You are right, the routines are basically decrementing / incrementing loops cutting the profile down to finished dimensions. There is no gouging calculation, the profiles that can be cut are limited by tool type, profile and mounting, and ultimately operator common sense. The work very well for me within those limitations but can certainly be improved upon. I look forward to your results. regards -- Learn Graph Databases - Download FREE O'Reilly Book Graph Databases is the definitive new guide to graph databases and their applications.

[Emc-users] Newbe intro and question
Greetings list, I getting ready to buy some hardware and setup CNC on a 3in1 machine. I'll be using LCNC with a parallel port and stepper motors. This is more of a hardware question. For an emergency stop I was planning on using a charge pump and wire the enable signal in series through it and a NC switch. I found one place that sells a BOB and emergency stop that wires the step signals for each axis through separate relays and all are opened when the e-stop switch is hit. The enable signal is not cut. There is a claim that:A trip instantly stops your stepper motors and puts on the electric motor brakes to stop the axis system in it's tracks. My question: Does stopping the step signal to the controller result in any sort of braking from some EMF in the motor that doesn't occur when the enable signal is stopped? Thanks in advance for any replies. -- Raymond Julian Kettle River, MN The things we admire in men, kindness and generosity, openness, honesty, understanding and feeling are the concomitants of failure in our system. And those traits we detest, sharpness, greed, acquisitiveness, meanness, egotism and self-interest are the traits of success. And while men admire the quality of the first they love the produce of the second. -John Steinbeck, novelist, Nobel laureate (1902-1968) -- Learn Graph Databases - Download FREE O'Reilly Book Graph Databases is the definitive new guide to graph databases and their applications.

Yes as the current would be maintained thus stopping the motor. removing the enable would drop the current and the steppers would be able to spin easier, they will still cog and reduce speed.

But their efficiency is a little bit lower, wich is not a problem because they are cheaper, so for the same peak power you will pay the same. but you need more surface to install them. All silicon PV panels lose some efficiency over time. The drop is fairly steep initially then tapers off to a very slow decline. Crystal panels take a hit of 3% to 5% their first year then about 1% per year for several more years. Dunno if that's 1% of original capacity or 1% of the reduced capacity each year. Amorphous panels will drop up to 10% of their initial efficiency in a few years, so an installation using them should be oversized by at least 10% above the amount of power required. Each manufacturer has different claims and guarantees about the efficiency loss over time, but it's always a safe bet to oversize the capacity by plenty then never expand the draw to use the extra. This efficiency loss is a good thing for building systems with used panels. Get well seasoned panels that have bottomed out on their initial rapid decline and you won't have to oversize the capacity - but get them tested for output in full sun. One extra-ordinary 30 year old panel still delivered 97% of its initial capacity (in 2010) and more amps than the spec sheet. (Had to dig this out of the archive as the current site has it paywalled.) https://web.archive.org/web/20100524144011/http://www.greenbuildingadvisor.com/blogs/dept/musings/testing-thirty-year-old-photovoltaic-module Temperature also has an effect on output, efficiency loss and the overall longevity of the panel. Keeping them cool (which is a bit difficult for a dark object placed into direct sunlight) reduces efficiency loss and increases output.

Re: [Emc-users] Announcing LinuxCNC 2.6.0-pre1
Gentlemen, congratulations to the announcement of 2.6! I was very pleased to find may name on the list of contributers although I must confess that, besides participating lively, but passively in the discussions (lurking), my one and only contribution so far was the translation of a couple hundred error messages into German, more than a year ago. Big honour. Since I have no commercial application for LinuxCNC, just a few machines used for hobby purposes, it's mostly platonian love for IT applications leading me to LinuxCNC and the discussions on this list. I have installed a CD version of EMC2 and made some sample millings, but did my real CNC milling work by foot so far, using EAGLE for the coordinates, Excel for the scaling, Word for syntax structure and forming Gcode files and a free sample software, including a 3D traverse planner, for execution. Lathe work was done very effectively with home made Basic programs, a 286 PC and an old Parker-Hannifin IEEE stepper driver, but that was long ago. But being mentioned, reminded me to take up this translating again, if I only knew where to get into that. Translating was relatively easy to do, so I could take it up now after some disturbances I encountered meanwhile. To be honest, translating into Bavarian would be even easier sometimes as Bavarian often has a concise way to express things most like English has (yes, Michael, Austrian and especially Tyrolian is linguistically a branch of Bavarian). The reason, as I see it, is that English and Bavarian have close common roots in Midle High German from which they are descendants, as opposed to today's High German which was composed rather artificlally, beginnig about matirn Luther's time. The spaces provided for the messages, as I remember, are sometimes a little short limited so High German text is sometimes hard to fit into them (frequently, I felt the urge to choose entirely different language structures or even re-arrange the error messages logically instead of translating). As Franz von Kobell put it: Der Preusse spricht den gesamten Denkvorgang mit, der Bayer gibt nur das Ergebnis bekannt. The Prussian (meaning: the High German speaker) pronounces the entire way of his thoughts, the Bavarian only the result. But it would be a pain for the rest of German speaking people reading messages in Bavarian, so ... Would someone please tell me how to enter the LinuxCNC site in order to contribute some more translations?

Hallo Andy, the links you posted a out of date! http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Translation is from 2012 and do mention under 7. Translations a Link to a document from 2009 with file lile tcl.pot, rs274.pot and axis.pot all the files do not exist any more, because someone merged all the translation in one monster file named linuxcnc.pot. Because this file is so large and many times you are not able to get the meaning of the message, I avoided it to begin to translate some stuff from that. IMHO it is the wrong way to merge all translations in one file, because you will not find anyone to translate 3500 lines of messages without comments of the meaning or the information to what part they belong! That is the reason, why I went a different way with gmoccapy and added my own translation files to /etc/po/gmoccapy, finding that way other people helping me with the translation. I am sure we will not be able to change that for the 2.6 release, but we should split off the monster linuxcnc.pot file to make clear where the translations belong to. I will go on with my GUI coding, so unfortunately I do not have spare time for translations.

That would be 400 Ohms. A 100 W vitreous ceramic resistor works well, they take momentary overloads easily. You could probably go a little lower on the resistance without trouble.

Re: [Emc-users] Announcing LinuxCNC 2.6.0-pre1 OT
Erik, 28 hours of language lessons should be plenty to order and eat Weißwürste in a Munich Bierkeller. Even kids under the age of one can speak Bavarian hereabouts. Earnestly: Danish is closer to English than Bavarian, I admit. But I did have little problems in Denmark reading things, more understanding spoken language. There is a rumor that all the languages are hard to understand which are used to scare and drive cows (e.g., besides Bavarian, also Netherlands, Danish, Schwyzerdütsch, Texan etc.) By the way: The tribes of the Saxons originally settled near the coast of the North Sea, around the Elbe river, partly in what is now Netherlands, partly what is now Niedersachsen (Lower Saxony). When they first arrived there, the sea retracted half a mile, and now it comes back every twelve hours to look if they are still there. Today's state of Saxony, part of the Federal Republic of Germany, has nothing in common with them except for the name, a consequence of feudal marriages. The name has to do with the indogermanic sax meaning a piece of rock (saxum in Latin), especially a stone knife, which shows how old this name must be. Later on, it signified a short, one bladed sword. In nordic langages it still exists a scissors, sax or saks. The Romans used it as a name for all kinds of pirates they encountered. Once you know the way how the languages have changed in the ages, their construction laws, it's easier to learn a related language - that's why I have difficulties with Chinese.

[Emc-users] reprap M104/109 function or G10 and M66 for setting and waiting on temperature?
Hi, I'm working on remapping M109/M106/M104 to something like M209 etcetera. I came across thishttp://reprap.org/wiki/Talk:G-code#M104_.26_M109_Deprecation.2C_G10_Introduction and I'm wondering about the way to continue. The M104 used in reprap style devices is for setting the temperature of the hot end, and M109 will also wait for the temperature to be reached before continuing. I'm wondering what is the right way to go. How do you normally use tools which are heated? You have to switch those tools on/of/set temperature. Is G10 the preferred way? Basically the temperature is dependant of the process (slicing, material etc) and not dependant on the tool per se. the following could be done: - set the temperature of the tool with a G10 - internally have the set temperature of that tool connected with the wcomp function - than wait with M66 on the out bit of the wcomp function? with G10 and M66 you could re-use basic functions. any thoughts on the logical and right way to do this?

[Emc-users] Silly bQ, nothing to do with Linuxcnc
Greetings; The hot water valve in our 35yo Maytag clothes washer has a screen in the inlet, and from the low flow is mostly blocked, full of lime. So I go get 2 fresh armored hoses, and some service screens for the solenoid valves, and pull it out to where I can sort of get to it. Unforch, the pair of bronze faucets that have been there since 1974 cannot be turned off, the screws threads are apparently both loaded up with hard water deposits over the last 30+ years, and a 12 pipe wrench across the top of the tee handles can't budge them. The Stem packing nuts are backed off about a turn each, I just soaked the stems with wd-40. I have an air hammer like you would put a chisel in to cut mufflers loose, would it to to let it buzz on the side of the stem to shatter the lime in th threads? Or would I just bust it off? Either way it looks like a trip out for 2 new faucets. I thought I had a can of PB Blaster, but its got up and left. Anybody have a better idea?

Not knowing any Middle High German, I tend to notice the similarities between the Danish Sønderjysk dialect and English, confirmed by reading that Saxon doesn't come from Sachsen, but further north, around Schleswig. Once you start looking, there's commonality all over the place, though often with a bit of vowel bending, and sometimes a systematic consonant softening which initially camouflages the strong connection.

So I just shut the whole house off long enough to pull the screens from the valves.

Re: [Emc-users] Silly bQ, nothing to do with Linuxcnc
One possible workaround is to mount valves on the old valve spout, where the hoses attach. It is definitely not the ideal solution, and takes a couple of extra adapters, but it will give you valves for the washing machine. Depending on the materials that the tee and the valve are made of you may end up replacing the tee if the valve won't come out. Raymond Julian Kettle River, MN The things we admire in men, kindness and generosity, openness, honesty, understanding and feeling are the concomitants of failure in our system. And those traits we detest, sharpness, greed, acquisitiveness, meanness, egotism and self-interest are the traits of success. And while men admire the quality of the first they love the produce of the second. -John Steinbeck, novelist, Nobel laureate (1902-1968) On 04/18/2014 10:20 PM, Gene Heskett wrote: On Friday 18 April 2014 23:10:44 Todd Zuercher did opine: You could try soaking the lime scale with some strong acid (lime scale remover).
