[01:32:32] <trentster1> Howdy, has anyone seen a auto Z probe routine ignore the limits for a Z axis as set in the .ini file?
[01:33:59] <trentster1> I have limits set for Z of Min and Max travel of +160 and -160 yet intermittently when I try and run a probe routine I get an immediate error " line 5 of probe routine would exceed the negative limit for that axis.
[01:35:16] <cradek> nope, there's no way to do that other than fix your g38.x destination to be within the machine limits
[01:35:32] <trentster1> This occurs when the routine only tells it to probe down 10mm and the current Z position both relative and absolute are e.g. 10 and 0 respectively.
[01:36:05] <trentster1> cradek: thats the point, my G38.x is within my machine limits
[01:36:48] <cradek> then I don't understand
[01:36:59] <cradek> you asked if you could make it ignore the limits - the answer is no
[01:37:15] <trentster1> 1 sec let me grab the code so I can show some tangible examples
[01:37:19] <cradek> ok
[01:37:39] <trentster1> my question is why does it ignore the limits , not how can I make it ignore the limits
[01:37:44] <cradek> (the destination has to be inside the machine limits, even if you expect it to hit something and stop before then)
[01:38:04] <cradek> oh I see! but it doesn't ignore the limits...
[01:38:43] <cradek> if you think it's doing something wrong, can you reproduce it in sim/axis and tell me how to do it here?
[01:39:18] <trentster1> cradek I can make the limits +200 and -200 and still the probe will fail with a move of 10mm when its currently sitting at relative z=17 and absolute z=0
[01:39:42] <trentster1> whereby it should only error out if it exceeds -200 or +200 correct?
[01:39:43] <cradek> that would be extremely surprising!
[01:40:06] <cradek> can you show me how to do it in sim/axis?
[01:41:17] <trentster1> I am just grabbing a past screenshot
https://monosnap.com/file/i8hxOG5A2SNL9VokEpTLr3Q2jWPw1D.png
[01:43:16] <cradek> you have both a g92 offset and g54 offset
[01:43:26] <cradek> you probably just aren't where you think you are
[01:45:23] <trentster1> cradek:
https://gist.github.com/trentster/b708157f1e3d304d1a93 Z azis is [AXIS_2]
[01:46:23] <trentster1> https://gist.github.com/trentster/0ccaa9e1ab82e15ac9c7 that is the Z probe routine
[01:47:50] <cradek> consider using G91 mode! you're nuking your work offsets
[01:47:51] <trentster1> so based on those gists surely the probe should work as long as I am within the limits of both Z positions as displayed in that screenshot?
[01:47:58] <trentster1> or am I missing something.?
[01:48:29] <trentster1> The weird thing is it sometimes works fine and sometimes gives the warning it will exceed negative limits
[01:48:53] <trentster1> Sorry I am a bit of a newb when it comes to gcode deep diving
[01:49:24] <trentster1> cradek: would you mind gisting an e.g. of a probe routine you think would be more suitable that would negate the issue?
[01:49:46] <cradek> I also notice if you're running a G20 program Z-10 would be outside of the -200mm limit
[01:50:31] <trentster1> I was following the article on
http://7xcnc.com/software/probing/z-touch-plate/
[01:52:16] <cradek> also check out
http://linuxcnc.org/docs/html/user/user-concepts.html#_when_you_8217_re_lost
[01:53:09] <trentster1> thanks - will bookmark that now
[01:53:11] <cradek> after probing you should use #5063 to get the result
[01:53:52] <trentster1> 5063?
[01:54:19] <cradek> see here:
http://linuxcnc.org/docs/html/gcode/g-code.html#gcode:g38
[01:55:20] <trentster1> cradek: thanks a ton, I really appreciate your help, this has been driving me nuts for ages ;-)
[01:55:59] <cradek> welcome! hope you get it going.
[01:56:20] <cradek> be sure to watch your offsets (see that "when you're lost") and your units
[01:56:47] <trentster1> I have to! - right now I would just be happy getting a probe routine to fire consistently
[02:02:46] <trentster1> cradek: What would you recommend as a good tutorial or resource to learning / understanding coordinate systems and gcode?

[15:29:56] <kwallace> All my machines are too big for watch work and not that convenient for clocks. I need to get a lathe with WW collets. I have a junk AA109 that I could rebuild and modify for WW but it was junk when it was new -- cute but still junk.
[15:30:37] <archivist> you would be surprised how small you can work in a larger machine
[15:33:58] <cradek> I agree with that
[15:34:50] <kwallace> I have to start with 1/16th or 3/32nds stock because these are my smallest 5C collets. I'm out'a luck for work holding existing staffs. Or I'm not clever enough yet.
[15:35:46] -!- Daerist has quit [Quit: Leaving]
[15:36:16] <cradek> to hold existing staffs drill a hole in a piece of brass and fix the staff in it with shellac
[15:37:24] <cradek> spin it and center it with a toothpick as the shellac hardens
[15:38:19] <archivist> and then hand rest, graver and stereo zoom microscope
[15:38:21] <cradek> shellac will hold plates/cocks on a flat too, and you can center a hole the same way
[15:40:03] <cradek> for flats, a shape like this is easier to warm:
http://www.ebay.com/itm/111839267437
[15:40:22] <cradek> the "tables" on mine are thinner than this
[15:40:35] <kwallace> I'll have to give that a try. I have seen videos by Steffen Pahlow where he uses shellac for work mounting,
https://www.youtube.com/user/spahlow
[15:41:35] <cradek> for a staff, you don't really need to drill, just turn a divot with your graver. try hard to get it to come to a point at the center, and your staff will center very easily
[15:42:44] <cradek> am I misremembering, or do you have a sherline lathe?
[15:43:14] -!- Tecan has quit [Quit: Live Long And Phosphor!]
[15:43:18] <archivist> I have used wooden chucks for gear, to machine the centre or rim on a barrel after the teeth are cut
[15:43:40] <kwallace> No Sherline here. HNC, Feeler and Zubal.
[15:44:26] <cradek> HNC would be a fine watch lathe :-)

[15:46:09] <kwallace> and:
http://www.wallacecompany.com/machine_shop/Craftsman_AA_109/Craftsman_109-07a.jpg
[15:46:13] <cradek> I made a sherline spindle-shaped thing out of a 5C blank
[15:46:30] <cradek> so I could mount the little sherline 4-jaw
[15:49:16] <cradek> maybe you could do a similar thing for WW, but not being hard I bet it wouldn't last very long
[15:49:37] <archivist> kwallace, you know you can code the path in gcode to generate the involute, no spreadsheet needed :)
[15:49:39] <cradek> you'd have to make a very silly drawbar
[15:51:49] <kwallace> I have been studying this link,
http://www.csparks.com/watchmaking/CycloidalGears/index.jxl to try to create the tool path for gears, but I don't have a handle on it yet.
[15:56:27] <archivist> I have hand ground up a cutter to be near enough for a clock date wheel, else over her we just use cutters from a british maker so rarely need the cycloidal maths

[16:07:45] <jepler> my post did finally post
[16:19:19] <jepler> The Gmail mail server send limit is approximately 100-150 emails per day when connected to the server from a remote email client" according to this undated e-mail
[16:21:31] <jepler> so far since setting up the system, it appears 286 e-mails have successfully been sent
[16:22:42] <jepler> .. 50 in the last hour
[16:23:14] <jepler> so we may be sending enough that gmail is rate-limiting us :-/

[16:41:52] <lair82> Hello Guys, I have been on the mailing list about copying files around between Wheezy and Ubuntu, and have been talking to some people on the #debian forum, For some reason when I edit my nc files, it is changing the permissions of the file, so it can't be accessed from any other machine on the network. Any thoughts as to what may be causing this?
[16:43:20] <lair82> I have tried mousepad, kate and gedit, and they are all doing it, I tried to change the umask, but the debian guys said that is going to have no effect on fixing whatever is going on with my machine
