[00:01:00] <JT-Shop> anyone bored tonight?
[00:01:09] <Tom_itx> absolutely
[00:01:16] <Jymmm> JT-Shop: Nope, going to court!
[00:01:27] <JT-Shop> scan this and see if anything wrong pops out at you http://linuxcnc.org/docview/2.5/html/gcode/overview.html
[00:01:44] <Jymmm> JT-Shop: cop wrote me up for traveling in the diamond lane, even though I was making a right turn. Though, he did tell me which days were his days off and that he was too busy with other cases to appear in court too.
[00:01:51] <JT-Shop> Jymmm: night court?
[00:02:11] <JT-Shop> he was getting the points lol
[00:02:14] <Jymmm> JT-Shop: I hit the clerks office at noon, he siad you wanna go tonight, I said sure.
[00:02:28] <Jymmm> JT-Shop: Yeah, cop quota.
[00:03:03] <Jymmm> I'm just lucky I only had to work half day today, perfect time to hit the traffic court.

[00:04:10] <andypugh> Is turning right a defence?
[00:05:31] <JT-Shop> Tom_itx: oh crap wrong link see this one http://linuxcnc.org/docview/2.5/html/gcode/gcode.html
[00:07:54] <andypugh> "Where axis words are optional, any omitted axes will have their current value." Perhaps "retain their original value"?
[00:09:28] <andypugh> And now I want to find a use for G[#101]
[00:10:05] <JT-Shop> ommitted axes values will not change
[00:10:33] <JT-Shop> yea, that makes more sense
[00:10:39] <andypugh> Hmm, passing a plane code number to a subroutine would be a good use of that
[00:12:00] <andypugh> JT, you do realise that you are moving further from "redneck" to "programmer pedantic" in your docs?
[00:12:54] <JT-Shop> holy crap
[00:13:11] <JT-Shop> some of that is still in programmer speak I think
[00:13:25] <andypugh> Hmm, in G0 the term "current traverse rate" is perhaps unclear. maybe use "current maximum speed"?
[00:13:27] <JT-Shop> mostly I added some example code today
[00:13:46] <JT-Shop> yea, that is leftover programmer speak
[00:15:08] <andypugh> And perhaps "feed rate" needs an "F" link?
[00:15:15] <andypugh> (in G1)
[00:15:27] <JT-Shop> yep, good catch
[00:15:55] <JT-Shop> and traverse has no meaning related to rapid or maximum rate
[00:16:14] <JT-Shop> I added the see ... sections for more info today too
[00:16:38] <JT-Shop> the more eyes the better
[00:16:54] <andypugh> And, getting really fussy, the "." after the second "G1" in section 4 has an extra space, and just wrapped onto the next line for me.
[00:17:19] <JT-Shop> the G1 . ?
[00:18:03] <andypugh> Yes.
[00:18:05] <A2Sheds> G1 always needs an Fx
[00:18:14] <JT-Shop> probably a trailing space, I'll check for them in the morning
[00:18:33] <andypugh> A2Sheds: Not on the same line it doesn't
[00:18:36] <JT-Shop> A2Sheds: it needs a Fx to be set but not on the same line as G1
[00:19:00] <A2Sheds> maybe i just add one to be safe
[00:19:07] <andypugh> Does 2.5 include multi-turn arcs? if so, they need a P
[00:19:14] <JT-Shop> or make it more clear to read
[00:19:21] <andypugh> (or at least a mention)
[00:19:45] <JT-Shop> ahh missing from the prototype but included in full turns sub
[00:19:56] <andypugh> Sorry, I just read to that paragraph.
[00:20:38] <JT-Shop> np, I appreciate the input
[00:23:22] <andypugh> I lose track in long sentences, can I suggest that "When programming arcs using a precision of less than 4 decimal places (0.0000) for inch and less than 3 decimal places (0.000) for millimeters can result in an error due to rounding." becomes "When programming arcs an error due to rounding can result from using a precision of less than 4 decimal places (0.0000) for inch and less than 3 decimal places (0.000) for millimetres.
[00:24:09] <JT-Shop> sounds better to me too
[00:24:27] <Tom_itx> sry i lost track of what you said
[00:24:45] <Tom_itx> andy is way head of me
[00:24:54] <Tom_itx> maybe i should start at the bottom
[00:25:01] -!- rob__H has quit [Ping timeout: 252 seconds]
[00:25:43] <andypugh> I am (a) at a loose end and (b) spent decades writing and proof-reading academic papers.
[00:26:14] <JT-Shop> what does "loose end" mean?
[00:26:32] <Tom_itx> anything like a 'loose cannon'?
[00:27:10] <andypugh> Is that not a phrase used in the US?
[00:27:27] <JT-Shop> not around here
[00:28:11] <Tom_itx> having too many loose ends to tie up means you're just too damn busy
[00:28:31] <andypugh> Hmm, http://www.usingenglish.com/reference/idioms/at+a+loose+end.html says "British English"
[00:28:55] <JT-Shop> ahh ok that makes sense
[00:30:09] <andypugh> anyway, for my next pedantic point, a missing IJK in a G2/3 isn't taken as zero in G91.1
[00:32:33] <andypugh> And, given that IJK arcs are a lot more trouble than R arcs, perhaps we should explain why they are "preferred". R is _so_ much easier
[00:32:33] <JT-Shop> where is that?
[00:32:50] <JT-Shop> that is there no?
[00:33:06] <JT-Shop> in 5.4
[00:33:30] <andypugh> OK, not got that far yet.
[00:34:42] <andypugh> And the previous pendantic point appears 3 times (once for each plane) in the phrase " If only one is specified, the value of the other is taken as 0."
[00:35:17] <JT-Shop> the sentence The center format arcs are the preferred... is a bit terse
[00:36:03] -!- skunkKandT has quit [Remote host closed the connection]
[00:36:38] <JT-Shop> If only one is specified, the value of the other is taken as 0 when G91.1 is set
[00:37:17] -!- PCCNC has quit [Ping timeout: 258 seconds]
[00:37:18] <andypugh> ... or the current value when G90.1 is set.
[00:37:46] <andypugh> (though I have _no_ idea if that is actually the right way round)
[00:38:19] <andypugh> Do we know the precision of P in G4? I am pretty sure it can be fractional.
[00:39:27] <JT-Shop> I've not tried anything less than 0.1 for G4 but assume it is the same precision as axes
[00:40:46] * JT-Shop wonders what the maximum precision of axes are?
[00:42:14] -!- H264 has quit [Ping timeout: 244 seconds]
[00:42:55] <andypugh> I would guess that for G4 is is either the servo-thread rate or the "mysterious other rate"
[00:42:57] <JT-Shop> The center format arcs are the preferred format for programming an arc due to the inaccuracies of some radius format arcs.
[00:43:46] <JT-Shop> that I don't have a clue about
[00:45:27] <JT-Shop> ah here it is Numbers may have any number of digits, subject to the limitation on line length. Only about seventeen significant figures will be retained, however (enough for all known applications).
[00:47:24] <andypugh> Section 13, G10 L10: I can only imagine that being useful in the context of a probe, so perhaps that should be linked too?
[00:48:27] <andypugh> And how long have we had G10 L11?

[00:49:05] -!- theorbtwo has quit [Ping timeout: 252 seconds]
[00:50:10] <andypugh> Section 16 could, perhaps, have a warning that UV WU and VW planes do not support arcs. (in fact, are they any use at all?)
[00:50:52] <andypugh> (though I see that that is mentioned in G2/G3)
[00:51:06] <JT-Shop> g10 l11 is new to 2.5
[00:51:52] -!- theorb has quit [Remote host closed the connection]
[00:53:03] <JT-Shop> good to mention it in both places as I found out this morning how users read the manual with Ctrl F and not the page up/down keys
[00:53:55] -!- theorbtwo [theorbtwo!~theorb@91.84.53.6] has joined #emc
[00:54:20] <JT-Shop> I have not come up with an example for G10 L11 yet
[00:54:23] <andypugh> Section 21, this just makes no sense, and has a typo(twice): "If the X Y coordinates specificed are not the current coordinates when calling G33.1 for tapping or the move will not be along the Z axis but will traverse from the current location to the X Y specificed."
[00:55:32] <JT-Shop> what happens if your not at the current coordinates it will move from the current to final while trying to tap at an angle
[00:55:44] <JT-Shop> quite interesting to see
[00:56:21] <JT-Shop> ... for tapping the move...
[00:56:27] <andypugh> I think you need to lose the "or"
[00:56:33] <JT-Shop> yea, see it now
[00:57:00] <andypugh> and "specified"
[00:58:05] <andypugh> I have found it is almost impossible to proof-read your own stuff, because you read what you meant, not what you typed.
[00:59:33] <andypugh> This is a good idea. It might save those perfect welds half an inch from the seam: http://www.machine-dro.co.uk/steck-mig-light-welding-gun-mounted-led-torch.html
[01:01:30] <JT-Shop> cool, I can't have enough light when welding
[01:02:13] <JT-Shop> and yea, I read what I meant not what I typed...
[01:03:13] <JT-Shop> dang led's are getting bright, the one I just got for my 870 will blind you... but that is what you want
[01:04:20] <andypugh> That site is worth a browse, if only for the vast range of differently-tipped digital calipers. (and that is where my 3" caliper came from)
[01:05:05] <andypugh> This is probably the most special: http://www.machine-dro.co.uk/gear-tooth-digital-calipers-.html
[01:05:19] <JT-Shop> hmmm, I don't see "dog end" on English Idioms and iirc that was the term Jethro Tull used

[01:05:49] <JT-Shop> wow, dueling calipers
[01:05:57] <andypugh> A "Dog End" is the last, barely smokable, bit of a cigarette (or spliff)
[01:06:14] <JT-Shop> spliff?
[01:06:49] <andypugh> "enchanced" cigarette?
[01:06:58] <JT-Shop> got ya
[01:09:50] <andypugh> I really ought to got some of these, but at about half the price of a digital caliper, perhaps I will just carry in scribing with calipers.

[01:12:55] <JT-Shop> I don't see lagniappe either
[01:13:17] <JT-Shop> must be a cajun thing
[01:13:19] <andypugh> Here's a high-workload suggestion. Links from the docs to youtube vids of the G-codes in action.
[01:13:39] <JT-Shop> ohh that would be neat
[01:14:15] <JT-Shop> here is one for offsets http://www.youtube.com/watch?v=G4-lUNa0CpY&list=UUt3eCzdbsQeuCifjsTyvvTg&index=2&feature=plcp

[01:17:15] <JT-Shop> 3 minutes till the dog barks, if you see any more I'll read back in the am
[01:17:24] <JT-Shop> thanks for the feedback Andy
[01:18:13] <andypugh> G33.1 exists from skunkworks. http://www.youtube.com/watch?v=jAcFeVlftrw
[01:18:28] <JT-Shop> lol peck tapping
[01:18:52] <andypugh> It's a good example if the fact that it waits for index
[01:19:30] <andypugh> (and good propaganda for EMC2 and Big Stuff
[01:19:35] <JT-Shop> yes, there is another one where a chap picks up the thread by moving the spindle by hand while the tapping routine is running
[01:19:53] <andypugh> That's G76 I think?
[01:19:58] <JT-Shop> yea
[01:20:09] <JT-Shop> rethreading or something
[01:20:27] <JT-Shop> eventually they all come over from the Dark Side

[01:21:18] <JT-Shop> or plasma
[01:21:21] <JT-Shop> or...
[01:21:22] <andypugh> Night!

[01:27:40] <andypugh> Hi Mr Sz
[01:28:13] <andypugh> I don't suppose you still have any laser engraving capability?
[01:28:17] <robin_sz> so why does this bit of crappy C i wrote to read the serial port, be magically turing 0x83 into 0x03 ... it seems to be masking off the high order bit on any char after an esc (ox1b) char ?
[01:28:22] <robin_sz> Hi Mr Pugh
[01:28:31] <robin_sz> well, odd you shoudl mention that ;)
[01:28:59] <robin_sz> I am off down to my mates 2mrw to play with his 25W CO2 engraver
[01:29:48] <robin_sz> its only CO2, not pulsed yag ... so dunno what it will do in steel
[01:30:43] <robin_sz> oh .. but I do have this:
[01:31:20] <robin_sz> https://picasaweb.google.com/robin.szemeti/Laserscope#5677083462216133522
[01:31:29] <andypugh> I spent an incredibly frustrating week of my PhD trying to work out my serial link hardware (MicroVax to PC, though at the time I didn't know it was a MicroVax) was sending random numbers, then wanted to flagellate myself when I finally noticed that it was a MSb LSb problem. Have you checked that?
[01:31:48] <robin_sz> everyting else is coming through perfectly fine
[01:32:18] <andypugh> 7 bit serial?

[01:32:31] <robin_sz> I monitor with a second port
[01:32:35] <robin_sz> and a perl script

[01:34:47] <andypugh> Missing wire in the cable?
[01:35:13] <cpresser> robin_sz: i had some similar issues once. it was all due to port settings
[01:35:17] -!- CmdrData has quit [Ping timeout: 240 seconds]
[01:35:26] <cpresser> i think with tcsetattr you got the culprit already
[01:35:34] <robin_sz> nope, same hardware. run the Perl script on /dev/ttyS1 .. stop it, run C on same prt
[01:35:56] <robin_sz> yeah, is there a "fuck about with my input" option?
[01:36:26] <andypugh> I love the failed attempt to vapourise a small boy later on.
[01:36:34] <robin_sz> yes, photshopped :)
[01:36:47] <andypugh> (disappointed)
[01:36:57] <robin_sz> the rest is 30W of 532nm
[01:37:20] <robin_sz> options.c_lflag &= ~(ICANON | ECHO | ECHOE | ISIG); is good for raw input, right?
[01:37:46] <andypugh> I hope you aren't asking me, I am trans-clueless
[01:38:03] <robin_sz> no, I ask cpresser I think, or, frankly anyone
[01:38:39] <robin_sz> you like that laser then? ;)
[01:39:02] <cpresser> honestly, i dont have a clue about those options
[01:39:11] <robin_sz> me netiher :)
[01:39:27] <cpresser> in the end, i wrote a perl script which compiled various C-programms and selected the working ones^^
[01:39:35] <robin_sz> heh
[01:39:43] <robin_sz> yeah, my Perl prootype works fine
[01:39:47] <cpresser> but i never had trouble using perl, python or java to access the hardware
[01:39:57] <robin_sz> but this is going on an embedded device
[01:40:01] <andypugh> Anyway, if you get bored, I would be keen to see if the laser can do a distinct 75lpi pattern on aluminium, brass, or austenitic stainless. (can't really use anything magnetic)
[01:40:03] * cpresser is a really bad code.
[01:40:21] <cpresser> +r
[01:40:33] <robin_sz> well, to save some time forget the brass and copper
[01:41:02] <robin_sz> you know what they make mirrors for CO2 lasers out of?
[01:41:24] <andypugh> Small boys?

[01:42:19] <robin_sz> ally and stanless will be OK I think
[01:42:35] <robin_sz> only 25W, will play 2mrw
[01:42:38] <cpresser> i also own a CO2-Laser (since 6 days), but i didnt have the guts to put in any metal.
[01:42:54] <robin_sz> how many watts?
[01:42:57] <cpresser> 80
[01:43:01] <robin_sz> oh nice
[01:43:19] <robin_sz> this is my friends ... I no longer have a CO2
[01:43:22] <cpresser> i need it to cut 12mm acrylic; 100W would have been better for that
[01:43:33] <robin_sz> 80 will be MORE thna enough
[01:43:44] <robin_sz> what focal length lens you using?
[01:43:50] <cpresser> 2" so far
[01:43:53] <robin_sz> noooo
[01:43:57] <robin_sz> 6" minimum
[01:44:13] <cpresser> <- has very few experience yet
[01:44:24] <robin_sz> for 12mm, do not use less than 6"
[01:44:33] <andypugh> Kerf?
[01:44:35] <robin_sz> yes
[01:44:43] <robin_sz> really wide kerf with 2" lens

[01:45:24] <cpresser> with larger focal lens i will get a larger spot, but more 'depth convergence'?
[01:47:04] <robin_sz> spot will be about same
[01:47:38] <robin_sz> but, if you put the focus point say, halfway through the acryllic
[01:47:51] <cpresser> spotsize is also crucial, i want to engrave the acrylic without changing the lens :)
[01:48:04] <robin_sz> spot size at top and bottom will be smaller than if you used 2"
[01:48:34] <robin_sz> well, 6" will give roughyl same spot size as 2"
[01:48:41] <cpresser> i only did a few tests with 'focus point benath the material surface'; so far they were not that good unfortunately
[01:48:50] <robin_sz> put focus on top of surface
[01:49:03] <cpresser> but i think i will learn a lot in the next few days and weeks... i am just a beginner :)
[01:49:09] <robin_sz> well, use 6" lens, really, 2" is very very short for cutting 12mm
[01:49:11] <andypugh> (Ramble) Me and my dad spent all of christmas very slowly making a puller for Freelander ABS sensors. (amongst the other engagements) Today we pulled it out and decided to check the condition of the target wheel (or "reluctor") having noticed that the end of the sensor was absent. It wasn't even turning, it had lost contact with the driveshaft and was wedged against the swivel hub casting. Quite a tight fit too. I blame Alien
[01:49:35] <robin_sz> heh
[01:49:45] <robin_sz> serves you right for buying a lorry

[01:53:57] <andypugh> OK, in the picture of small boy and laser, I am not geeky enough to identify the lathe, what is it? I can tell it is english not american, but not a lot more.

[01:59:28] <andypugh> Though, looking at my Dad's Smart and Brown, I might look at one of those for a CNC conversion. They are leadscrew-only, with the screw in the middle, under the bed. They have no headstock gearing, so make a nice VFD lathe, (my dad's has a retrofitted friction-variable-speed-drive) and a very wide bed for the size. Only drawback is plain-bearing spindle and a limited through-bore.
[01:59:58] <robin_sz> plain bearing spindle?
[02:00:06] <robin_sz> since when was that a good idea?
[02:01:24] -!- tom3p [tom3p!~tomp@74-93-88-241-Illinois.hfc.comcastbusiness.net] has joined #emc
[02:03:31] <andypugh> They were the only way, at first, and got quite good. In fact for precision work they were preferred into at least the 60s. The Smart and Brown has taper-adjustable bronze bearings, as has my big Triumph. The small lathes (Boley etc) used hardened steel in hardened steel to great effect.
[02:04:30] <robin_sz> doh!!!
[02:04:35] <robin_sz> reading into a CHAR?
[02:04:43] <robin_sz> max size of a char is ...
[02:04:48] * robin_sz beats head on desk
[02:05:02] <andypugh> And, if that link you gave was the same lathe, that is the exact same lathe that the RCSMC have, and I have no excuse for not recognising it.
[02:05:21] <andypugh> Nor have you an excuse for not using uchar
[02:05:25] <robin_sz> it is,
[02:05:38] <robin_sz> the tail end of motorbik on RH side is my GSXR
[02:07:21] <robin_sz> does ANSI C have uchar?
[02:07:25] * robin_sz suspects not
[02:07:38] <andypugh> I would love a CNC Student, but I would have to bin so many high quality parts.
[02:07:44] <Tom_itx> uint8_t

[03:17:41] <GregK> I finally have a stable setup on my pc. Now I realize I have no idea what to do to get the Mesa 5i25 card going. is there a good configuration for EMC to start with? Anything else that needs to be done for the card drivers, etc.?
[03:18:35] <Tom_itx> get the 5i25 drivers and add them to the ini
[03:18:45] <skunkworks_> GregK: you have a 5i25? Latency isn't as critical for high step generation
[03:19:05] <GregK> yes
[03:19:06] <skunkworks_> (because the 5i25 is generating the pulses)
[03:19:12] <GregK> oh
[03:19:20] <GregK> well it's stable now anyway
[03:20:03] <GregK> So putting a Mesa card in any box will make a good machine?
[03:20:28] <Tom_itx> you need decent latency
[03:20:56] <Tom_itx> mesa cards make things alot nicer
[03:21:02] <GregK> so the 1,200,000 I was seeing wouldn't acceptable..:-p
[03:22:04] <skunkworks_> heh - no. but the 25000 is more than good enough
[03:23:17] <GregK> Ok so that's good. Is there a thread on the forum I should be looking at to set up Mesa? I'm sifting through threads now.
[03:24:22] <Tom_itx> probably not for that one since it's so new

[15:41:51] <anonimasu> yeah, but it makes sense for touching off workpieces(manual states that)
[15:41:54] <anonimasu> and for setting up tools
[15:43:18] <pcw_home> Yeah you need to be front and center to jog
[15:48:09] <pcw_home> little hard to see the DRO though
[16:08:41] <toastydeath> goddamn that's a nice lathe
[16:13:51] <Mjolinor> http://www.lathes.co.uk/grayson/
[16:13:59] <Mjolinor> I hav eone of those, that's anice lathe also :)

[17:28:11] <syyl_ws> uh
[17:28:11] <elmo40> nice indeed.
[17:28:14] <syyl_ws> nice
[17:28:25] <elmo40> small swing, mind you.
[17:28:30] <syyl_ws> working? or going for emc?
[17:28:34] <elmo40> maybe 10" ?
[17:36:32] <mazafaka> JT-Shop: How much would fan improve the heat exchange from the wood stove to the air?
[17:37:51] <archivist> depends on the heat exchanger and air speed
[17:38:20] <JT-Shop> what Dave said
[17:40:27] <JT-Shop> I have one behind mine solely to circulate the heat in the shop
[17:46:51] <Loetmichel> so, ER11.collet holder done. Why must a little tidy be so much work? ( the rest of the collets are MIA somewhere in my CNC-corner ;-) -> http://www.cyrom.org/palbum/main.php?g2_itemId=12620
[17:47:11] <archivist> reminds me of heat transfer calcs for heatsinks on power stages
[17:47:38] <Loetmichel> have to make the Wrences out of something more rigid than FR4... maybe steel? ;-)
[17:48:29] <archivist> porper wrenches are cheap enough
[17:48:32] -!- theorbtwo [theorbtwo!~theorb@91.84.53.6] has joined #emc
[17:48:34] <archivist> proper
[17:49:00] <Loetmichel> archivist: to big for the space under the collet on my CNC.
[17:49:06] <Loetmichel> smaller ones would be better
[17:49:58] <elmo40> use 4140 for the wrench
[17:50:22] <elmo40> cromoly steel is great for wrenches
[17:50:59] <mazafaka> 1.5 KW heater with fan were quite good, why not use fan with the stove then. I think all the heat goes out of the garage
[17:51:01] <JT-Shop> get danimal_laptop to make you one from titanium
[17:51:04] <archivist> putting that steel on his mill would break the mill unless his cuts are very small
[17:55:34] <elmo40> it will be a thin wrench. approx 0.100" (2.5mm)
[17:55:50] <elmo40> make 10 passes at 0.010" ;)
[17:58:26] <archivist> I learnt how flexible mill doesnt work well with steel when I first got mine running :)
[18:01:30] <Loetmichel> my MILL is not flexible
[18:01:51] <Loetmichel> but the steppers are not very powerful
[18:01:58] <Loetmichel> so small cuts are ok
[18:02:14] <Loetmichel> i will test it wit a bit mild steel laying around here

[18:07:28] <archivist> Loetmichel, it looks flexible to me as the column looks small
[18:08:10] -!- IchGucksLive [IchGucksLive!~chatzilla@95-89-244-199-dynip.superkabel.de] has joined #emc
[18:08:25] <archivist> use a dial indicator to test fix to table and measure to head, push on the head
[18:09:18] <Loetmichel> the colum is 65*70mm square "tube" made out of 8mm thick aluminium sheet and a bag of M4 steel screws
[18:09:45] <archivist> mine was that small. I had to fix it
[18:10:03] <Loetmichel> it is WAY more rigid than the stappers can do for ;-)
[18:10:41] <archivist> steppers is not where the bending force comes from, its the tool
[18:11:12] -!- psha [psha!~psha@213.208.162.69] has joined #emc
[18:11:29] <Loetmichel> that are 0,7Nm steppers direct coupled to a 10mm acme "screw" with 8,466 tpi
[18:12:30] <archivist> work out the rotating energy available in a cutting tool with the mass of the spindle motor
[18:12:34] <Loetmichel> archivist: the tool runs with 24kRPM. The most forces are canceled by the mass of the HF-spinle
[18:12:45] <archivist> you machine WILL bend
[18:12:57] <Loetmichel> of coures
[18:13:00] <Loetmichel> course
[18:13:13] <Loetmichel> there ios nopthing like a not bending frame
[18:13:19] <Loetmichel> how much is the question
[18:13:35] <Loetmichel> it IS possible to mill a hammer head
[18:13:56] <Loetmichel> 0,1mm cut in Z though, but possible
[18:13:57] <archivist> as I said measure, you will be surprised how easy a machine bends with a kilo side force
[18:14:32] <Loetmichel> archivist: the linear ways are 4mm ball bearings running naked with the outer ring on 10mm round steel
[18:14:46] <Loetmichel> THERE will be bending much more than in the column
[18:15:29] <Loetmichel> but for my work its ok and mills to the thou if i have enough time and dont hurry it ;-)
[18:16:01] <JT-Shop> somebody want to push up on the head while I rotate it back vertical?
[18:16:48] <archivist> use a sky hook and a pulley
[18:17:27] <Loetmichel> jeah, tahts something i have missed quite some times... a sky hook ;-)
[18:17:37] <IchGucksLive> Loetmichel: in germany there are the epson laserjet steppers available for 12 euros at 2,4V 1,5A 2Nm driving at 24V this is a good combination
[18:17:47] <JT-Shop> the sky hook is over the lathe at the moment
[18:18:08] <archivist> its on wheels isnt it?
[18:18:10] <Loetmichel> IchGucksLive: not neccessary
[18:18:11] <JT-Shop> and if I had built it 3" shorter the BP would still be sitting on the trailer
[18:18:22] <Loetmichel> the mill runs fine with te vextas
[18:18:24] <JT-Shop> it's not that heavy reall
[18:18:29] <JT-Shop> really
[18:19:10] <Tom_itx> are you measuring flex with a ruler or a dial indicator?
[18:20:18] <IchGucksLive> is there anywhere a example how to build a spindle motor fro a lathe on emc
[18:20:29] <Loetmichel> Tom_itx: who, me?
[18:20:35] <Tom_itx> yeah you
[18:20:42] <Loetmichel> i COULD measure it with a dial indicator
[18:20:51] <Loetmichel> but i dont want to know it ;-)
[18:20:56] <Tom_itx> i bet
[18:21:27] <archivist> when you break a few cutter it is time to know
[18:21:40] <Loetmichel> and frankly: I have seen the dial indicator a few days ago... but dont ask whre the magnet base for it is ;-)
[18:22:02] <Loetmichel> ... i have NO idea
[18:23:05] <archivist> Tom_itx, I have an indicator of 100th of a thou on its own stand, it can sense a little finger on the column
[18:23:37] <Tom_itx> i bet that was cheap
[18:23:53] <GregK> out of curiosity how much HD is needed these days for EMC2 and Ubuntu? I was setting up on a 4GB CF and I'm runnign out of space.
[18:24:01] <Tom_itx> mine's just .0005" last word dial
[18:24:12] <Tom_itx> err .0001 i forget
[18:24:18] <archivist> cannot remember the cost (probably army surplus)
[18:24:28] <syyl_ws> i was suprised how much a real mill can bend...
[18:24:30] <Tom_itx> laser refraction
[18:24:34] <syyl_ws> from light hand-force
[18:25:07] <archivist> and small ally columns move about 10 thou probably
[18:28:20] <IchGucksLive> GregK: you made somthing wrong there is a xbuntu rti with less then 200MB

[18:41:32] <Loetmichel> sooo, found the dial indicator. not as bad as i thougt: -> http://www.cyrom.org/pce/columnflex.avi (3MB, xvid) that is a 0,01mm dial, meaning pressing between 3 and 5kg gets you about 0,1mm flex. and: NO play in the acme threads. fine for me ;-)
[18:42:34] <IchGucksLive> Lois this a FFp230
[18:42:46] <IchGucksLive> Loetmichel:

[18:51:05] <Loetmichel> GregK: very impressing
[18:51:26] <Loetmichel> but i think to buy a china spindle will be cheaper than the material alone ;-)
[18:51:36] <Loetmichel> s/impressing/impressive
[18:52:07] <archivist> very good set of pictures
[18:52:10] <GregK> Yes, china spindle is cheaper, but I wanted to be able to cut steel with power.
[18:52:26] <GregK> I need to balance before final assembly

[19:01:34] <Loetmichel> extended
[19:01:46] <GregK> yeah that's about what I'm at, only 360MB left..
[19:01:48] <Loetmichel> in x direction it flexes much more
[19:02:19] <GregK> 430MB after dumping non essential progs.
[19:03:08] <archivist> Loetmichel, torsion in the column I went up to 150-200 mm per side on the column to get better
[19:03:35] <GregK> I have to grab some lunch thanks for the help!
[19:04:41] <Loetmichel> archivist: normally i have 0.8mm or 2mm tungsten carbide mill bits in the spindle
[19:04:56] <Loetmichel> so i have seldom more forces than a few 100 grams

[20:27:55] <pcw_home> too bad it cant be sent back postage due
[20:31:03] <GregK> pcw glad to see you if you ahve a minute. I'm looking at the Mesa 0 configuration page and see the "Sanity Checks" does the selection here make any difference?
[20:31:18] <GregK> I have 5i25 and 7i76
[20:32:31] <GregK> OK, I gues I don't have any of those boards, so I unchecked what was checked by default

[20:45:58] <syyl> closed loop stepper :D
[20:45:59] <syyl> works!
[20:50:51] <emcrules> syyl, How did you close the loop?
[20:51:24] <syyl> glas scale -> mesa 5i20 -> emc :D
[20:52:00] <emcrules> I figured that part. I meant with the steppers in paticular
[20:53:37] <syyl> i used that hal as a basis

[20:56:29] <JT-Shop> GregK: you don't need the sanity checks for the 5i25/7i76
[20:56:58] <JT-Shop> I need to get mine hooked up to the plasma
[20:57:12] <emcrules> JT-Shop got my phase converter for my mill
[20:57:14] <syyl> now i need a second glas scale for the y axis..
[20:58:23] <JT-Shop> cool
[20:58:27] <emcrules> Fanuc OM runs fine on 245, 245, 250VAC
[21:00:48] <emcrules> I bought a ready to go unit. Silly buggers put the schematic inside it with all the cap values for all horsepower models
[21:01:22] <emcrules> now i can build my dad one lol
[21:02:08] <JT-Shop> emcrules: have you ran yours yet?
[21:02:31] <emcrules> Running right now
[21:02:43] <JT-Shop> I am real interested in how well the voltage balance is?
[21:03:07] <JT-Shop> self starting?
[21:03:12] <emcrules> Yup
[21:03:25] <emcrules> Phase quest
[21:03:36] <JT-Shop> do they have a 15hp listed on the schematic?
[21:03:39] <emcrules> leeson motor with a bunch of caps
[21:03:46] <emcrules> thats what mine is
[21:04:15] <emcrules> Im running a kitamura mycenter zero with no problems
[21:04:41] <emcrules> on a 40 amp breaker
[21:04:49] <JT-Shop> what is the start cap(s) values
[21:04:53] <emcrules> should have a 80 amp breaker
[21:05:08] <emcrules> one sec i have to take off the cover
[21:05:20] <JT-Shop> mine is on a 50
[21:07:12] <emcrules> shit i cant take off the cover irs running and the push button wires are attached to the cover
[21:07:27] <emcrules> i will take it off tonight and get back to you
[21:07:46] <emcrules> making brackets for my router right now
[21:08:15] <GregK> The pc looks like it's ready. It looks like I'll be OK with the 4GB CF after all. Now, it's time to finish the machine.

[21:19:49] <Loetmichel> only at cold boot i could get it up
[21:20:02] <Loetmichel> so i switched to a normal 80gb HDD

[22:06:07] <cradek> that is the wrong answer
[22:06:14] <cradek> http://linuxcnc.org/emc2/dists/lucid/base/binary-all/
[22:06:32] <cradek> unless you have very special requirements you should get it from our apt repository

[22:09:25] <clytle374> cradek, thanks. Might I ask why the bitfile should change?
[22:09:39] <clytle374> isn't there some new wonder wizard for the mesa cards?
[22:09:53] <cradek> well in general they change when they get added features or bugfixes
[22:09:58] <cradek> I'm not sure if that's what you are asking
[22:10:16] <cradek> there is pncconf
[22:11:56] <clytle374> yeah, that was the question. I assume I should get the newer of the 5i20 packages
[22:14:04] <cradek> http://linuxcnc.org/emc2/dists/lucid/base/source/hostmot2-firmware_0.8_amd64.changes
[22:14:14] <cradek> looks like version 0.8 added support for dual 7i48 setup
[22:14:31] <cradek> so yeah, always get the newest
[22:15:44] <PCW> EMCs repository bit files are pretty old but the only bug I know of is the muxed encoder velocity estimation scaling bug
[22:15:46] <PCW> all the newer stuff is for sserial, resolvers or newer fpga cards/daughtercards
[22:16:19] <clytle374> I got http://linuxcnc.org/emc2/dists/lucid/base/binary-all/hostmot2-firmware-5i20_0.8_all.deb
[22:16:29] <clytle374> much easier than building my own last time
[22:18:21] <clytle374> PCW, I'm using a 7i48, I remember it has mux so do I need diff .bit files?

[22:19:13] <clytle374> I might be using a pendant card later... matter?
[22:19:19] <PCW> There is a bug in the velocity estimate in the repository bitfiles
[22:20:12] <clytle374> Should I use the ones from mesanet?
[22:20:16] <PCW> velocity estimate will be a factor of 16.66 too low on a 5I20
[22:20:44] <clytle374> I've seen that number before. lol
[22:21:26] <PCW> well its pci cllock/2
[22:22:40] <clytle374> oh, I was thinking 1/6
[22:23:04] <clytle374> are the mesanet files the newest?
[22:24:59] <PCW> it was a copy/paste error in the muxed encoder section which meant the
[22:25:00] -!- GregK has quit [Quit: Bye Bye]
[22:25:01] <PCW> timestamp rate register never got setup so instead of being set for 1 MHz
[22:25:02] <PCW> the default value ended up being pciclock /2
[22:26:21] <clytle374> such things happen
[22:26:52] <PCW> The source at mesanet is the latest but not all the bitfiles are
[22:26:54] <PCW> I expect this to all be much better when Sebastians buildbot is making the latest
[22:28:35] <clytle374> I've got the old bit file I made ~2 years ago, I can use that for now.
[22:29:01] <PCW> the funny thing about the velocity estimation erro on muxed encoders
[22:29:02] <PCW> is that no one noticed (you can tune around it if you use the velocity estimate in a PID loop)
[22:29:04] <PCW> until samco tried to get the spindle RPM from the velocity estimate
[22:30:04] <PCW> The bad thing now is that if people update their bitfiles, they may have 16.66 or 25 times as much D term as they used to have
[22:30:59] <clytle374> No way to flag that to warn people is there?
[22:31:19] <clytle374> One of my encoder input will be from the spindle

[22:31:50] <PCW> I think the driver (2.5 or >) has a flag to warn you to update your firmware
[22:31:52] <clytle374> getting the compiler was ugly, and used a weeks worth of bandwidth, so I'm not building it again
[22:33:05] <clytle374> can it warn about the error?
[22:33:17] <PCW> Well you never actually had to build it (I can always supply latest bitfiles)
[22:33:19] <PCW> But I'm hoping Sebs buildbot work will obviate that
[22:33:58] <clytle374> It was for the 7i48 about 2 years ago.. I built it to prove I could..
[22:35:09] <clytle374> can you get me one for 5i20 and 1 7i48? also got a 7i37 and not sure what I'm doing on the 3rd port yet
