#emc-devel | Logs for 2007-06-08

[00:00:02] <jepler> yeah I sure understand
[00:00:10] <jepler> we also got in well after dinnertime last year
[00:00:36] <jmkasunich> are you gonna have your cell on?
[00:05:22] <cradek> jepler: let's load tomorrow
[00:05:34] <cradek> it would be great to get up, shower, and leave on saturday
[00:05:36] <a-l-p-h-a_> I won't ask.
[00:45:52] <cradek> jepler: do you want to fix those obsolete comments in the ppmc configs?
[00:54:34] <cradek> forget it
[01:01:19] <cradek> build build build
[01:07:13] <SWPadnos> cradek, maybe we should spend a little time making my fast machine into a .deb builder
[01:07:39] <SWPadnos> I just haven't had the time/mindshare to do it yet
[01:08:00] <jepler> cradek: sorry, I don't think I ever got around to fixing it
[01:08:08] <cradek> are you volunteering to do the 2.2 series of releases if I help you get going?
[01:08:15] <jepler> cradek: loading tomorrow sounds great
[01:08:15] <SWPadnos> sure
[01:08:36] <cradek> jepler: no problem, jon doesn't care I guess
[01:08:53] <cradek> SWPadnos: cool, let's talk about it more then
[01:08:55] <SWPadnos> I think it may be fast enough to do separate packages for dapper and feisty as well
[01:08:58] <SWPadnos> yep
[01:09:25] <SWPadnos> I bought a couple of extra hard disks as well, so we can experiment with fresh installs and the like
[01:09:31] <cradek> the board is supposed to assign a release manager for each new branch - it's just been me so far
[01:09:47] <SWPadnos> maybe I'll open an ssh port for you ;)
[01:09:58] <cradek> I have 2x 9G in my box, only one is used
[01:10:16] <SWPadnos> I'll have 3x320G, with two unused :)
[01:10:33] <SWPadnos> unless I decide to grab the hot spare from the server RAID, in which case it'll be 4
[01:10:37] <cradek> is your gpg key in the keyservers?
[01:10:43] <SWPadnos> no
[01:11:04] <cradek> we'll have to work out keys
[01:11:05] <SWPadnos> since I had to think about what you said, and I've never done anything related to that, I'm sure no is the correct answer
[01:11:23] <cradek> ok that's fine
[01:11:34] <cradek> we have some time to work on it (not today or tomorrow)
[01:11:48] <SWPadnos> right
[01:11:52] <cradek> I'm going to try to get this CD made tonight
[01:11:56] <cradek> ... and pack
[01:12:01] <cradek> fat chance, I'm sure
[01:12:11] <SWPadnos> I have to figure out why my wife's computer decided to spontaneously lose all her desktop settings and email
[01:12:22] <cradek> ouch
[01:12:24] <SWPadnos> (Ubuntu Feisty, so no Windows jokes, please)
[01:12:25] <SWPadnos> yeah
[01:12:35] <cradek> lose as in can't find, or lose as in delete?
[01:12:45] <cradek> (the mail)
[01:12:47] <SWPadnos> at least I've finished the robot controller, other than the defective motor drive (I think)
[01:13:02] <SWPadnos> lose as in Thunderbird asks about creating a new profile
[01:14:02] <cradek> * cradek makes a face at thunderbird
[01:14:04] <SWPadnos> heh
[01:14:22] <SWPadnos> not only is the profile file gone, I think the mainl store is gone as well
[01:14:28] <SWPadnos> mail store
[01:14:30] <cradek> just because it's the best gui 3-pane standard mailreader doesn't mean it's good
[01:14:42] <SWPadnos> no
[01:14:46] <cradek> that's a new one on me
[01:15:05] <SWPadnos> she had actually had another problem, and couldn't shut down
[01:15:20] <SWPadnos> so obviously the thing to do in that situation is power doen with the power button ...
[01:15:51] <cradek> that's harmless nowadays
[01:15:58] <SWPadnos> even ctrl-alt-del didn't work. I wonder if it's due to my plugging in a different keyboard - maybe it wasn't considered the promary
[01:16:11] <jmkasunich> do we have anybody bringing a printer yet?
[01:16:20] <SWPadnos> yeah, I figured that whatever was happening before was the real problem
[01:16:21] <cradek> did you look in lost+found?
[01:16:24] <cradek> jmkasunich: not me
[01:16:25] <SWPadnos> yep, empty
[01:16:40] <cradek> did you look on your last backup tape?
[01:16:41] <SWPadnos> jmkasunich, not me either, unless I have room for the laser
[01:16:54] <SWPadnos> I'm sorry, I didn't understand that :)
[01:16:56] <jmkasunich> I have a small laser, networked even
[01:17:03] <cradek> :-/
[01:17:04] <SWPadnos> that machine has no backup system at all
[01:17:14] <jmkasunich> I'm not sure how well lasers travel though
[01:17:21] <SWPadnos> yeah - mine is a network PS and HPGL laser
[01:17:30] <cradek> jmkasunich: might take the toner out and put it in a plastic bag
[01:17:30] <jmkasunich> ISTR something in the packaging about never ever ever ship one with a toner cartridge installed
[01:17:34] <SWPadnos> they're great, just take the toner cartridge out
[01:17:41] <cradek> ha
[01:17:47] <cradek> that must be the right advice
[01:17:53] <SWPadnos> or we're all wrong
[01:18:07] <SWPadnos> 60/40 that it's the right advice ;)
[01:18:40] <cradek> (1/2)^3
[01:18:48] <jmkasunich> spiral taps and machinable wax. I coulda swore I had some was, but last time I looked I couldn't find it
[01:18:51] <SWPadnos> hmmm. that's not great odds
[01:19:14] <SWPadnos> I can bring some Al blocks for hte Mazak
[01:19:15] <cradek> jmkasunich: the taps are more important of the two
[01:19:17] <SWPadnos> relatively large ones
[01:19:32] <cradek> jmkasunich: (and matching drills)
[01:19:37] <SWPadnos> do we want tapping head(s) for comparison?
[01:20:16] <jmkasunich> size is a tradeoff
[01:20:29] <jmkasunich> larger won't break, but they'll use up a lot more material
[01:20:50] <cradek> and cost more when I manage to break them anyway
[01:20:58] <jmkasunich> I have 3/8-16 spiral, 5/16-24, and #6,8-32
[01:21:23] <SWPadnos> I'm not positive I have the right kind, but I can also bring several somewhat smaller ones (if I can find them)
[01:21:40] <SWPadnos> actually, they may be the same threads you just mentioned
[01:22:24] <jmkasunich> those are pretty standard
[01:22:36] <jmkasunich> 6-32 spiral is easy to break
[01:22:47] <jmkasunich> I also have a couple of weird ones
[01:22:58] <jmkasunich> like 5/16-32, and 1/4-40, very find for their size
[01:23:24] <jmkasunich> hmm, question for Roland: what toolholders does he have?
[01:23:29] <SWPadnos> hmmm. 1/4-40 is a great one for fine adjustment of big things ;)
[01:24:22] <jmkasunich> correction, 1/4-48 ;-)
[01:24:28] <SWPadnos> even better ;)
[01:24:52] <SWPadnos> we had an optics pointing device with two screws that were something like #6 or #8, 64-pitch
[01:24:59] <jmkasunich> nice
[01:25:14] <jmkasunich> I have 1/2-20 too, not spiral tho
[01:25:44] <jmkasunich> somewhere, I know not where, I have a piece of gray PVC plastic 1" x 4" x 24"
[01:26:25] <SWPadnos> I'll be happy to see the difference between the "right" tap for CNC tapping (with a tapmatic or rigid tapping) and "not the right ones" :)
[01:26:38] <jmkasunich> back to the toolholding though - unless roland has a drill-chuck for the mazak, we aren't likely to be drilling or tapping
[01:27:00] <SWPadnos> will the BP have spindle orient this year?
[01:27:03] <jmkasunich> SWPadnos: what do you mean?
[01:27:04] <SWPadnos> I have R8 holders
[01:27:28] <jmkasunich> you mean the bp that was sitting in the doorway last year?
[01:27:32] <SWPadnos> I think JonE wants to make one of the BP retrofits do tapping this year
[01:27:46] <jmkasunich> I seriously doubt it has a spindle encoder
[01:27:53] <SWPadnos> that's part of his "push" to get the index thing fixed
[01:27:58] <SWPadnos> hmmm
[01:27:59] <cradek> I wonder how he intends to do that :-)
[01:28:11] <SWPadnos> damfino ;)
[01:28:48] <jmkasunich> cradek: your lathe spindle doesn't reverse does it?
[01:28:53] <cradek> no unfortunately
[01:29:15] <cradek> I'm not sure what would be involved because I don't know what kind of feedback it has
[01:29:58] <jmkasunich> SWPadnos: what did you mean by "the difference between the right tap for CNC"
[01:30:09] <skunkworks> for tapping - 'by hand' would be a good test (for the lathe)
[01:30:10] <cradek> I also don't have a motorized tailstock
[01:30:25] <cradek> very true, I could just turn it
[01:30:30] <jmkasunich> cradek: I wasn't thinking of the tailstock
[01:30:31] <SWPadnos> oh - I think Tapmatic recommends spiral taps vs "hand taps"
[01:30:36] <jmkasunich> clamp the work to the table
[01:30:42] <jmkasunich> SWPadnos: oh, that
[01:30:50] <cradek> http://www.sherline.com/reverse.htm
[01:30:54] <SWPadnos> when I look at MSC, they have about 15 kinds of tap, and I have no idea what the real differneces are
[01:31:03] <jmkasunich> for thru holes, spiral _point_ are best, for blind holes spiral flute
[01:31:23] <jmkasunich> duh, I was looking only at spiral flute, I have a wider selection of spiral point
[01:31:44] <cradek> A current surge that can instantly burn out the speed control can occur if the switch is thrown in one direction while the motor is still turning in the other direction.
[01:31:58] <jmkasunich> heh, here's one cradek can break: 7/16 BSW
[01:32:12] <SWPadnos> "Bull Shit Weight" ?
[01:32:12] <jmkasunich> ok, so not reversing the lathe
[01:32:23] <jmkasunich> british standard whitworth I think
[01:32:26] <SWPadnos> heh
[01:35:20] <jmkasunich> http://www.hgrindustrialsurplus.com/search-products/product-detail.aspx?id=40-715-470&searchtable=1&sortExpression=&SortASC=&pageSize=50&currentPageIndex=0
[01:35:23] <jmkasunich> wonder what that is?
[01:35:43] <SWPadnos> it's a tapper
[01:35:50] <jmkasunich> well no chit
[01:35:53] <SWPadnos> heh
[01:36:08] <SWPadnos> it looks to be in rough shape
[01:36:12] <jmkasunich> doesn't look like the usual procunier or tap-matic
[01:36:36] <SWPadnos> it's similar to a Commander (I have a couple, if you want one)
[01:36:44] <jmkasunich> heh, cradek won'
[01:36:48] <jmkasunich> won't break these: http://www.hgrindustrialsurplus.com/search-products/product-detail.aspx?id=42-120-058&searchtable=1&sortExpression=&SortASC=&pageSize=50&currentPageIndex=0
[01:36:49] <SWPadnos> it looks more like a rigid tap
[01:37:03] <jmkasunich> I have a procunier #2
[01:37:31] <SWPadnos> ok. I think that's similar to a Tapmatic 50 (or SPD5)
[01:39:16] <jmkasunich> when I hit HGR tomorrow I'll see if there are taps for cheap
[01:40:25] <jmkasunich> bins like this are kinda fun to root thru
[01:40:58] <jmkasunich> http://www.hgrindustrialsurplus.com/search-products/product-detail.aspx?id=30-304-957&searchtable=1&sortExpression=&SortASC=&pageSize=50&currentPageIndex=1
[01:41:21] <SWPadnos> damn - now there's a spindle motor: http://www.hgrindustrialsurplus.com/search-products/product-detail.aspx?id=12-246-635
[01:41:31] <jmkasunich> heh
[01:41:53] <jmkasunich> this looks kinda neat: http://www.hgrindustrialsurplus.com/search-products/product-detail.aspx?id=30-344-002&searchtable=1&sortExpression=&SortASC=&pageSize=50&currentPageIndex=1
[01:41:59] <SWPadnos> 4500RPM - that's pretty fast for such a big motor
[01:42:17] <SWPadnos> yeah, that is cool
[01:43:08] <cradek> emc2-ubuntu6.06-desktop-i386.iso 0% 2576KB 42.1KB/s 4:29:59 ETA
[01:43:16] <cradek> arg.
[01:43:18] <jmkasunich> ouch
[01:43:29] <SWPadnos> ok. I should spend a little time with my visiting sister before I leave for a week. see you guys tomorrow (IRC) and Sunday (real life)
[01:43:38] <cradek> safe trip swp
[01:43:38] <jmkasunich> goodnight
[01:43:45] <SWPadnos> that's faster than my upload speed :(
[01:43:59] <jmkasunich> anybody need drills: http://www.hgrindustrialsurplus.com/search-products/product-detail.aspx?id=42-103-105&searchtable=1&sortExpression=&SortASC=&pageSize=50&currentPageIndex=1
[01:43:59] <cradek> I could put it on a tape and drive to work...
[01:44:02] <SWPadnos> which is the main drawback to my building ISOs and .debs
[01:44:10] <cradek> right
[01:44:17] <cradek> guess why I don't do it very often
[01:44:21] <SWPadnos> heh
[01:47:37] <jmkasunich> how difficult would it be to build debs on virtual machines?
[01:47:56] <SWPadnos> it's the upload that kills you
[01:48:06] <SWPadnos> but with VMs, it may be the build as well :)
[01:48:32] <jmkasunich> my new box is pretty quick
[01:48:44] <jmkasunich> I'm gonna get the farm moved over to it while I'm at the fest
[01:48:56] <jmkasunich> seems like the farm machines ought to be able to build debs too
[01:49:23] <SWPadnos> try doing a full build in a VM and not in a VM on that machine
[01:49:36] <jmkasunich> iaven't set up vmware yet on it
[01:49:56] <jmkasunich> its probably 2:1, but thats still not bad
[01:50:12] <jmkasunich> building a kernel would take a while, but not building EMC
[01:50:37] <cradek> it's not really much time to wait for the builds - it would be the same effort on an infinitely fast machine
[01:51:36] <SWPadnos> ok. I'm really leaving now. good luck at HGR tomorrow :)
[01:51:41] <jmkasunich> goodnight again
[01:51:52] <cradek> bye
[01:53:02] <jmkasunich> I should try to remember to call Roland tomorrow and ask him if he has a drill chuck for the mazak
[01:53:07] <jmkasunich> tap holder too
[01:57:06] <jmkasunich> cradek: you need a machine AT work, do build the debs on
[01:57:19] <jmkasunich> or the iso's anyway
[01:57:58] <cradek> I definitely could do that.
[01:58:16] <cradek> this'll be there tomorrow, which is soon enough though
[02:04:03] <cradek> jepler: taking camera equipment?
[02:04:21] <jepler> cradek: if I remember I'll bring my canon with 18-55 and 100mm macro lenses
[02:04:23] <jepler> if I don't, then I won't.
[02:05:06] <cradek> um ok, should I then?
[02:05:47] <jmkasunich> I'll have my point-n-shoot
[02:06:09] <cradek> ok
[02:06:31] <jmkasunich> I kinda wish I was keeping my server online
[02:06:32] <cradek> I shouldn't bother then
[02:09:20] <cradek> ok if the mesa card isn't in the machine, it won't show up in lspci, even though it's packed
[02:09:36] <jmkasunich> ?
[02:09:54] <jmkasunich> you need lsboxes
[02:12:03] <cradek> that would be great!
[02:22:18] <jmkasunich> even better would be "findboxes" and "fillboxes"
[02:27:04] <jmkasunich> cradek: did you solve your noise issues with ferrite? need any more ferrites?
[02:27:29] <cradek> the lathe is working perfectly now, except for the PS being a little saggy
[02:27:36] <jmkasunich> ok
[02:27:45] <cradek> thanks though
[02:28:14] <jmkasunich> I'll toss a comple in a box anyway, we might use them for something else
[03:33:55] <SWPadnos> what about the threads component? :)
[03:34:05] <SWPadnos> heh
[03:40:36] <jmkasunich> threads and motmod are the exceptions
[03:40:53] <jmkasunich> and threads will go away sometime, when we have "newthread" as a command
[03:41:27] <SWPadnos> heh. I didn't want to mention ...
[13:02:18] <jepler> I wonder what benefit there is to having task and io separate now
[13:02:39] <alex_joni> jepler: actually I wonder why io shouldn't be in RT
[13:02:41] <jepler> I get the impression that in the past (emc1) the way to customize was to replace io with a different program that knew the details of your I/O hardware
[13:02:56] <alex_joni> e.g. merged with the motion controller
[13:03:05] <alex_joni> jepler: that's correct
[13:03:28] <alex_joni> but it also was split in 3-4 different controllers just to prove the flexibility/design of NML
[13:15:31] <alex_joni> jepler: does a new translation count as a new feature?
[13:31:46] <jepler> I'd say a new translation is fine to include during a release series, if that's the question you're asking.
[13:32:04] <cradek> figures. I just released last night.
[14:40:13] <jmkasunich> OK, I think I have the wiki updated for 2.1.6
[14:40:23] <jmkasunich> I'll leave the linuxcnc parts for alex_joni
[14:40:43] <cradek> thanks
[14:40:47] <cradek> I sent the customary email
[14:40:52] <jmkasunich> np
[14:42:18] <jmkasunich> * jmkasunich prepares an HGR shopping list
[14:49:12] <jepler> "packages like Mach 2 that have a step and direction output for the spindle. The step pulse is converted to an analog level (the pot) and the step direction contact is in place of the FWD/REV switch. "
[14:49:59] <cradek> oh, it's just pwm
[14:50:00] <jepler> sounds a tiny bit like how I abused freqgen to get pwm(pdm)+direction for servo motors before the pwmgen component came along
[14:53:07] <jmkasunich> yeah
[14:53:52] <jmkasunich> can anybody think of anything else I should look for/at when I'm at HGR?
[14:54:30] <jmkasunich> gonna try to find cheap taps for cradek to break'
[14:57:41] <skunkworks> do we take bets on how many will break before it is working ;)
[14:58:02] <jmkasunich> that depends on what material he's trying to tap
[14:58:14] <jmkasunich> wax would be nice
[14:58:17] <jmkasunich> plastic
[14:58:21] <jmkasunich> aluminum
[14:58:33] <jmkasunich> 4140 heat treated ;-)
[18:31:00] <alex_joni> I'll be doing the SF stuff in a second too
[19:57:00] <jmkasunich> cradek: around?
[19:58:11] <SWPadnos> ok - just got the quick ref cards
[19:58:18] <jmkasunich> how'd they turn out?
[19:58:28] <SWPadnos> they look pretty good, and now we know the correct decisions to make for another batch ;)
[19:58:42] <SWPadnos> (I'd probably go with the 5 mil lamination, for one)
[19:58:44] <jmkasunich> which decisions are?
[19:59:25] <SWPadnos> the text of the G-code side is a little small. some folks with imperfect vision or low-level shop lighting may have a hard time reading them
[19:59:32] <jmkasunich> I was afraid of that
[19:59:37] <SWPadnos> other than that, they're nice
[19:59:58] <SWPadnos> I think a two-column table, rotated 90 degrees would be better for that
[20:00:06] <jmkasunich> yeah
[20:00:19] <jmkasunich> next time around I think I'd like to enter it into easycad
[20:00:28] <SWPadnos> but since that's a royal PITA, I'm happy with the result :)
[20:00:56] <SWPadnos> did you find anything else fun at HGR?
[20:01:02] <jmkasunich> found a mill for Cradek
[20:01:10] <SWPadnos> cool
[20:01:29] <jmkasunich> unfortunately shipping will probably cost darn near the same as the mill
[20:01:38] <jmkasunich> he lives in the middle of nowhere
[20:02:04] <SWPadnos> I know the problem quite well
[20:03:05] <jmkasunich> it seems in quite nice shape
[20:03:13] <jmkasunich> http://www.hgrindustrialsurplus.com/search-products/product-detail.aspx?id=30-166-001
[20:03:25] <jmkasunich> the price is now $999
[20:03:35] <SWPadnos> nice
[20:03:41] <SWPadnos> that's about 7' tall, right?
[20:03:47] <jmkasunich> 7'2, more or less
[20:03:57] <jmkasunich> not counting the pallet it sits on
[20:04:13] <cradek> I live in the middle of the *country*
[20:04:29] <jmkasunich> actually, thats one of the problems for transport - if its less than a certain height, it can go on a common carrier, which is much less expensive
[20:04:33] <SWPadnos> and we're going nowhere, so therefore ...
[20:04:34] <jmkasunich> hi cradek
[20:04:42] <cradek> hi!
[20:05:10] <alex_joni> hi guys
[20:05:35] <cradek> I called HGR, he didn't have any ideas about Lincoln, but there's a local company called "Heavy Company" who moves about anything
[20:05:40] <jmkasunich> the QC spindle is fine - it just took slightly more torque than I could get with my greasy bare hands
[20:05:50] <cradek> cool
[20:05:56] <cradek> found a wrench?
[20:06:03] <jmkasunich> local to you, or to hgr?
[20:06:13] <jmkasunich> yeah, found a whole tub of them
[20:06:16] <cradek> local to me
[20:06:55] <cradek> "gantry to 1 million pounds" says their ad
[20:07:00] <jmkasunich> http://www.sjdiscounttools.com/arm34-307.html
[20:07:05] <jmkasunich> thats the kind of wrench you use on the spindle
[20:07:28] <jmkasunich> although you can use a non-adjustable one, or even make one pretty easily
[20:07:32] <cradek> do you know if it's a normal taper?
[20:07:39] <jmkasunich> I think its a 30
[20:08:48] <cradek> the problem is going to be the garage door being less than 7'2 tall
[20:08:59] <cradek> actually 7'2 + palette is probably ideal
[20:09:00] <alex_joni> that's only a minor detail
[20:09:05] <cradek> yeah, just tip it on its side
[20:09:10] <cradek> :-/
[20:09:17] <alex_joni> I think it's a matter of velocity
[20:09:20] <alex_joni> to make it fit
[20:09:20] <jmkasunich> its a dirt floor, right?
[20:09:24] <jmkasunich> dig a trench
[20:09:32] <cradek> nope, I'm putting it on concrete
[20:09:48] <alex_joni> and the door .. is that over concrete too?
[20:09:50] <cradek> yes
[20:11:39] <alex_joni> bummer
[20:12:25] <SWPadnos> no, that's easier - get rid of the concrete and that's probably enough extra space ;)
[20:13:05] <jmkasunich> remove from pallet outside, put on 1/2" diameter steel bars, and roll it
[20:13:19] <alex_joni> < cradek> the problem is going to be the garage door being less than 7'2
[20:13:29] <cradek> garage door is 7'0
[20:13:45] <SWPadnos> or take the somewhat less easy route and remove the head assembly
[20:14:05] <jmkasunich> cradek: you measured it already?
[20:14:17] <cradek> yes
[20:14:26] <SWPadnos> removal should be only 4 bolts plus whatever hoses/cables go up there
[20:14:33] <jmkasunich> heavy though
[20:14:46] <SWPadnos> you can use an engine hoist to move it around
[20:14:49] <SWPadnos> (once you get it down)
[20:15:25] <jmkasunich> if you could remove the head here, you could greatly reduce shipping cost
[20:15:37] <jmkasunich> because head and machine on seperate pallets would go in any old truck
[20:15:49] <jmkasunich> for delivery to a freight terminal
[20:15:55] <jmkasunich> instead of a dedicated truck
[20:16:03] <SWPadnos> maybe even on the same pallet - put the head sideways on the table (with the knee lowered)
[20:16:21] <jmkasunich> pallets are cheap
[20:16:27] <SWPadnos> shipping hem isn
[20:16:32] <SWPadnos> shipping them isn't
[20:16:41] <jmkasunich> balancing the head on the table won't be fun tho
[20:16:59] <SWPadnos> wood shims and ratchet straps ;)
[20:17:05] <cradek> where can you lift these things?
[20:17:23] <SWPadnos> there's a 5/8 eyebolt hole on top (of the manual machines at least)
[20:17:23] <jmkasunich> thats a good question
[20:17:39] <SWPadnos> and people use a forklift under the ram (on the manual machines)
[20:17:40] <jmkasunich> HGR will be happy to forklift it onto a truck using the pallet
[20:17:49] <cradek> in the photo, it's not on one
[20:17:51] <jmkasunich> the CNC doesn't have the ram
[20:17:54] <jmkasunich> it is now
[20:17:57] <cradek> ok
[20:24:12] <jmkasunich> finally: http://www.cox-internet.com/drspiff/machining/collets/tapers.htm
[20:24:23] <jmkasunich> I'm about 99% sure its a NMTB-30
[20:24:31] <cradek> jmkasunich: do you recall: would the machine be any less deep without that back cabinet?
[20:24:49] <jmkasunich> yes, I believe the back cabinet adds about 8"
[20:27:02] <jmkasunich> you'd have to remove the side cabinet too though
[20:27:25] <jmkasunich> because its right hand side (when view from the right side of the machine) is flush with the back of the back cabinet
[20:27:35] <cradek> ah ok
[20:39:03] <cradek> ouch, "heavy company" said probably $1500 (half day of work) for the last few miles :-/
[20:40:28] <cradek> I think they could do it though.
[20:44:00] <SWPadnos> got a friend with a flatbed pickup trruck?
[20:44:29] <alex_joni> * alex_joni vaguely remembers that SWPadnos was talking about a truck
[20:44:31] <SWPadnos> or, put another way, $100 +/- a case of beer may get you a friend with a flatbed pickup truck
[20:44:44] <SWPadnos> it's a pirate trrrrruck ;)
[20:45:32] <cradek> seems like the forklift is more a problem than the truck
[20:45:40] <SWPadnos> a flatbed doesn't need a forklift
[20:45:50] <SWPadnos> they have winches
[20:45:52] <cradek> oh the tipping kind?
[20:45:56] <SWPadnos> yep
[20:50:06] <alex_joni> ok, sourceforge release and linuxcnc page updated with 2.1.6
[20:54:53] <jmkasunich_> cradek: still there?
[20:55:11] <cradek> yes
[20:55:15] <jmkasunich_> did you see the message from Jon E
[20:55:27] <jmkasunich_> he will be working on the bport at the workshop
[20:55:38] <jmkasunich_> nice opportunity to see what you might be getting yourself into
[20:55:39] <cradek> yes I'm anxious to have a better look at that one
[20:55:46] <jmkasunich_> then make a decision
[20:56:11] <cradek> for instance, maybe some part other than the full head comes off the top
[20:56:19] <jmkasunich_> right
[20:58:05] <jmkasunich_> jmkasunich_ is now known as jmkasunich
[20:59:01] <jmkasunich> I was thinking about spindle speed control - replace the air motor with a nema 23 stepper, use the spindle encoder for feedback
[20:59:20] <jmkasunich> the only thing you'd have to do manually is gearchanges
[20:59:45] <jmkasunich> "the spindle encoder" being the one you'll have to add of course, the mill doesn't have one
[20:59:55] <jmkasunich> but I'm sure you want to do rigid tapping ;-)
[21:00:35] <cradek> probably not on day one, but yes
[21:00:55] <cradek> bbl
[21:01:02] <cradek> thanks again jmk
[21:02:06] <jmkasunich> you're welcome
[21:38:05] <alex_joni> safe trip guys
