Hey, I have 25+ years on you, and I manage (most of the time) :) According to my calendar. I think I hung a new one last winter sometime... That could be dangerous. Yes, and of course the pee stops. :) I have to tell a story here though. Coming home after Christmas at the farm near Ithaca a coup[le of years ago, on I-68 west of Cumberland, it started blowing snow in golf ball sized flakes, doing about 30 mph crossways of the road. My Dee gets nervous in those conditions cuz I'm an old Iowa farm kid who learned to drive the winter of 1949-50, somewhat legendary for bad weather and roads. So I just keep on trucking as fast as visibility allows. Booming down one of those grades someplace around Negro Mountain at about 50 mph, with maybe 100 feet of visibility if the tail lights of the next rig came on, my wife said: "You know don't you, that if you ever sell this truck, you are going to have to explain the cuts in the passenger grab rail are from your wife's fingernails?" I busted out w

And you know what? They're going to change the month -again- in just a few days. I can't keep up any more! This coming Sunday is actually 24 November. Right? I will be home: can't risk going out in this condition. A mere 4 hours along the Future I-86. Heck, you could sneak out & back before supper and nobody'd notice. Now, after eight hours on the road, you might be as disconnected from reality as I was after returning from near Harrisburg PA on Tuesday, through the Pocono Snows. Driving always dumbs me right down to room temperature. Must. Recalibrate. Caffeine. Delivery. System.

Re: Problem with the new hm2_pci write function

Sebastian Kuzminsky — 2008-11-20T02:29:31

Yes, the excellent debugging files you provided definately show a bug in the driver. The bug only manifests when there are no pwmgens enabled, and I guess except for you, all the hostmot2 users are on servo machines. Hold on, I'll fix it... Ok, I just checked the bugfix into CVS (TRUNK and 2.2), if you can update and recompile that should fix it. If you can't or don't want to compile from source, you can work around the bug by enabling one pwmgen instance in your config modparam. Assuming, of course, that you dont need those IO pins for GPIO... Thanks for helping us find this! Your help is much appreciated.

Hi, I want to bring up to date you about my sleepless night and my .write function. Please read my lasts messages to understand my problem. First, I have commented the addf hm2_5i20.0.write servo-thread line in the configuration file and I have launched EMC2. All works right, but there's no write function latched to servo-thread. After I have executed in the terminal the command: halcmd show all (output very long and I can copy only the last part) dmesg (entire response) The output are available in my site: http://www.robomatek.com/files/test.txt After, I have made a proof... I think that to solve the problem it's better to split the part to understand which make problem. So I have made a .hal file that I have executed by terminal after start up the realtime. After loaded the source file, I have put "halcmd start" in the command line, and my PC crashed down!... Fortunately, I have saved the "dmesg" response in a file. Here, the .hal source file: http://www.robomatek.com/files/test.hal and the dmesg re

TRUNK users: some obsolete drivers will be removed inJanuary!

Sebastian Kuzminsky — 2008-11-19T16:05:17

This message affects only users who run CVS TRUNK and also use two old obsolete Mesa 7i43 drivers. I think there are exactly zero of you, so, None, here's fair warning. The following drivers will be *removed* from CVS TRUNK in January 2009. They will not be removed from the 2.2 branch. * mesa7i43-gpio: This is an old GPIO-only driver for the Mesa 7i43. It has been superseded by the new hostmot2 and hm2_7i43 drivers, which work much better. * m7i43_hm2: This is an old driver for HostMot2 on the Mesa 7i43. It was sort of an early prototype for the current hostmot2 driver system. It has been superseded by the hostmot2 and hm2_7i43 drivers, which work much better. If you use either of those two obsoleted drivers in TRUNK, now's the time to switch to hostmot2 and hm2_7i43. The m7i43_hm2 driver in 2.2 will stay, but it wont be in 2.3 when that comes out.

Ed Nisley — 2008-11-19T13:48:31

I've offered to show off my Sherline CNC setup for a couple of folks from the Sherline list who are thinking about buying one. After considerable to-and-fro-ing, we've settled on this coming Sunday, 24 September. If anybody else is interested, c'mon over... I figure you guys all know more than I do about EMC, so anybody who shows up can keep me straight. We'll shoot the breeze, see how the CNC thing works, talk about EMC & G-code & stuff like that, and play with shiny toys. No agenda, no schedule, no sales pitches. I'm in Poughkeepsie, NY, halfway up the Hudson between NYC and Albany, inconveniently located quite far from nearly everywhere else. Drop me a note for details. Show up before noon-ish and you'll get in on some cold-cut lunchy things. If you're not out by suppertime, you'll be forced to eat something then, too...

Re: G54 -P out of range

Chris Radek — 2008-11-19T04:33:13

Here is where we my results differ. When I do this second G10, the G54 origin is put back at the unoffset machine origin as expected (in AXIS you can even see the axes move and the cyan unoffset-origin point disappears). The displayed position is now 2,2,2 as expected.

Re: G54 -P out of range

Stephen Wille Padnos — 2008-11-19T03:47:13

I don't understand what you're trying to do. G10 sets an origin, it does nothing to the work volume (except shift its position). Please explain the following: 1) What are you trying to accomplish? (I know you've told us, but I don't understand "change the volume", so please try to explain again) 2) What steps are you taking to accomplish your goal? Step by step please, don't leave anything out. Show us the G-code, tell us the mode changes (auto/MDI/jog ...), everything. 3) How are you determining that what you want is not happening? Are you expecting the user interface (which one, by the way) to change? Are you looking at the var file? What do you expect to see that you're not seeing? Hopefully the information on how to do what you want is in the manual (somewhere near where Chris pointed you), but it may be that EMC can't do it, or that there's another way to describe what you're trying to do. - Steve ------------------------------------------------------------------------- This SF.Ne

Re: G54 -P out of range

Chris Radek — 2008-11-19T03:23:42

OK, I see - you are expecting the var file to be written immediately but this is not a guaranteed behavior. It gets written at various times but not after every block. It is certainly written at shutdown so the coordinate systems are saved. Is it true that the machine motion is correct in all cases, including when setting an active coordinate system, and the system origins are saved when EMC exits and then restored on the next run of EMC? The var file is a way for the interpreter to save some values - it's not meant for "human consumption". If you need to interact with the var file directly, you can be sure of getting consistency by doing it when EMC is not running. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect

Re: How can I reduce the DAC noise

Stuart Stevenson — 2008-11-19T03:13:40

Gentlemen, I agree with Jon on this. If the servo amp has tuning you cannot disable then the EMC2 tuning is superimposed on top of the servo amp tuning. This drastically inhibits the tuning capabilities of EMC2. thanks Stuart On Tue, Nov 18, 2008 at 8:49 PM, Jon Elson public.gmane.org> wrote: ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/
