[00:15:47] <Dave911> JT-Dev: ... I was snooping on the emc-devel IRC .... How do your overrides work? Are you using a knob with a binary output or ?? I like the idea of using a pot type knob to override feed rate.
[02:44:30] <EricKeller> if the machine moves the commanded distance, shouldn't the dro show the correct distance?
[02:45:28] <pfred1> EricKeller that'd depend on the elasticity of the duck tape holding said mechanics together
[02:46:02] <EricKeller> my son wanted some of my duct tape earlier, I said "get your own duct tape"
[02:52:26] <morfic> did he ask for Duct Tape or Duck Tape?
[02:53:34] <pfred1> when they silverized duck tape it became duct tape
[03:00:12] <EricKeller> I always called it duct tape, but it's no good for ducts
[03:00:46] <pfred1> initially it was developed to seal ammo boxes for the pacific theatre in WWII
[03:01:16] <pfred1> which is where it got the name duck tape being water resistant
[03:01:51] <pfred1> but in the 50s when the GIs came home they all remembered the stuff and it morphed into duct tape
[03:02:13] <EricKeller> it has been shown to be medically effective in removing warts
[03:02:54] <Valen> EricKeller that one hasn't been confirmed as far as I'm aware, last I read said it was about the same as a bandaid, IE keep it wet and it'll get soft
[03:03:30] <EricKeller> I read there has been a study
[03:05:14] <Valen> http://en.wikipedia.org/wiki/Duct_tape_occlusion_therapy
[03:05:52] <pfred1> there are about 200 different grades of duct tape today
[03:06:18] <pfred1> somes different than others I'd imagine ...
[03:30:45] <morfic> the jog while paused thread is growing quick
[03:40:13] <tom3p> any advice on moving a 4300lb machine 400 miles? can it be done with a truck (say F250) and a tip up style flatbed?
[03:41:25] <pfred1> most pickups are 1 ton or less rated
[03:41:30] <cradek> get bids from uship.com
[03:42:02] <pfred1> yeah you can rent a big truck from u Haul or somebody
[03:42:13] <cradek> no, you really can't
[03:42:27] <pfred1> I'd say go with rental you don't want that sort of wear and tear on your own vehicle
[03:42:42] <pfred1> cradek you can't what?
[03:42:55] <pfred1> cradek because I've rented class C trucks off u haul
[03:43:09] <pfred1> with 17,500 pound capacities
[03:43:19] <cradek> can you drive that without a cdl?
[03:43:29] <pfred1> it isn't articulated
[03:43:35] <pfred1> its a straight body
[03:44:01] <cradek> still at that weight and distance I'd get a real trucker to move it for me. it really isn't very expensive.
[03:44:16] <pfred1> yeah u haul ain't cheap either
[03:44:31] <pfred1> that distance you're talking like a grand
[03:44:43] <cradek> and consider 800 mi of diesel
[03:44:59] <tom3p> uship.com thx!
[03:45:03] <pfred1> their trucks burn regular
[03:45:27] <cradek> tom3p: worked great for me (about that weight, a little less distance)
[03:45:33] <pfred1> or should i say burn through
[03:46:16] <pfred1> but yeah you will go through a couple hundred in fuel too
[03:46:36] <tom3p> i lucked out & can inspect the machine myself. i got some work from Cleveland (breakdown) and install (OldCastle CA )
[03:47:04] <cradek> maybe roughly $400 fuel
[03:47:56] <tom3p> thx again, gnite
[03:48:06] <pfred1> when I got my mini mill off harbor they shipped it yellow freight I think
[03:48:39] <pfred1> but it was only 733 pounds
[03:49:18] <cradek> mine was about 8000 lb, 300 mi
[03:49:58] <pfred1> I keep thinking about trying to buy a deuce and a half
[03:50:11] <pfred1> you know for those special purchases
[03:50:48] <pfred1> also there's that scene in Rambo where he drives over the cop cars ....
[03:52:10] <pfred1> I should go talk to Sam Calagione about military vehicle fetishes
[03:56:56] <Dave911> tom3p: You can put 4300 lbs on a car carrier pretty easily. That is really not that much weight. The trick is that you really need a 3/4 ton truck or heavier to pull a trailer with 2 tons on it, or a half ton setup just right. You can rent a truck up to 26,000 lbs gvwr and drive it without a CDL through most of the USA.
[03:57:15] <pfred1> Dave911 23:47 -!- tom3p [~tom3p@208.255.36.3] has left #emc ["Leaving"]
[03:57:42] <Dave911> Oh.. missed him .... now I see it!
[03:58:54] <cradek> I emailed him some more info too
[03:59:42] <cradek> I think you'd be smart to have a trailer with brakes... 2t + 1t of trailer = a lot of weight to stop
[03:59:56] <Dave911> Definitely...
[04:00:18] <Dave911> Tow vehicle must be in good shape also...
[04:00:24] <pfred1> yeah running serious weight down the road is a life reaffirming experience
[04:00:33] <cradek> yes you better have a darn good truck.
[04:00:58] <Dave911> A typical car trailer is 2000-2500 lbs if it is a lighter one ... empty
[04:01:17] <cradek> yep mine is right around 2500 I think
[04:01:48] <cradek> a u-haul would be much lighter I'm sure :-/
[04:02:25] <Dave911> If you have a good 1 ton truck and the right gooseneck trailer you can actually move 15,000 lbs pretty easily, more if you have a really good trailer
[04:05:17] <Dave911> More than that, then you really need a semi rig.. which requires a CDL ... unless you have farm plates on it ..
[04:06:16] <cradek> I'm not too proud to call in the pros when something's too much for me (or my equipment) - my 8000 lb mill sure was that
[04:07:04] <cradek> 4300 lb, somewhat easier, but still probably too much for a car hauler if you actually check the numbers on it
[04:07:24] <Dave911> 8000 lbs is a lot to move and rig without some good equipment. You might be able to move it, but how do you unload it!
[04:08:04] <cradek> ah I had to do that myself... just rented a teleoperator
[04:08:57] <Dave911> Depends on the car hauler... Most of them have two 3500 lbs axles -- so the GVWR is 7000 lbs. Two tons for the load leaves you with 3000 for the trailer, so it should work. Trick is to tie it down right. Don't want 4300 lbs of machine coming through your back window!
[04:09:23] <Dave911> teloperator .... I remember you saying that you rented one??? That was probably not cheap!
[04:09:47] <cradek> nah it was fine, a couple hundred, don't remember for sure
[04:10:25] <Dave911> Having the right equipment available is everything....
[04:10:41] <Dave911> cradek: Did you catch the jog while paused discussion on the email list?
[04:10:52] <cradek> oh god
[04:11:05] <Dave911> well said
[04:11:50] <Dave911> I'm not sure that Steve doesn't already have what he wants ... but he just doesn't realize it ..
[04:12:33] <cradek> you can't currently restart mid-move which I think is important to him
[04:12:56] <cradek> you probably can't quite restart on an arc right either, not sure
[04:13:13] <Dave911> I have never heard him say that .... that I recall, but you might be right about that .... hadn't considered that ....
[04:14:07] <cradek> well fwiw I doubt you really want that in the case he describes (insert breaks - you notice - pause - jog away - replace insert - resume - it feeds to the point where you paused and then continues)
[04:14:27] <cradek> in that case you'd leave some uncut (the part that went by before you paused)
[04:14:54] <Dave911> Right.. so you'd have to run the last move anyway .. if the insert broke..
[04:15:22] <cradek> so I guess you'd have to restart some other way (probably a lot like the way emc can already do now)
[04:16:11] <Dave911> So I am still thinking that he may really not have an issue at all... I asked him to try the run from here .... along with Les' tool change alteration ... but apparently he hasn't done that yet ...
[04:16:44] <cradek> thanks for trying - he's pretty hard to help
[04:17:04] <Dave911> I think that most of his gcode is cam generated so the O loop thing should not affect him ... with no O loops ..
[04:17:35] <Dave911> >>he's pretty hard to help.... agreed .... NP
[04:17:47] <cradek> yeah that's a big obstacle to a general solution - he says he doesn't care if/how that works - kinda inadequate as a spec
[04:17:59] <Dave911> Steve helped me out before with a cam software problem I was having so I was trying to return the favor
[04:18:40] <Dave911> >>he says he doesn't care if/how that works - kinda inadequate as a spec ..... Needs a bit more work I'd say ... ;-)
[04:19:18] <Dave911> I think he just wants someone to pass a magic wand over EMC2 and have it show up ..... not so easy ...
[04:19:31] <Dave911> Oh well..
[04:19:54] <cradek> yeah some things are quick and easy to add - unfortunately this is not quick or easy
[04:20:12] <Dave911> I can see why....
[04:20:46] <Dave911> I heard a while ago that someone was developing another User interface for EMC2 called Mocha .... have you heard about that?
[04:20:58] <Dave911> Is that real or vaporware?
[04:21:28] <cradek> I think that's not quite the right name - I can't remember what it is - but I've seen screenshots of it
[04:21:47] <Dave911> OK ...
[04:22:38] <Dave911> The Eztrol software that was done for Smithy .... was that closed source or ?? I heard that used QT ??
[04:23:11] <Dave911> Someone was asking about that the other day I saw...
[04:23:13] <cradek> it was/is qt - I think it's open source - I'm not sure how to get it though
[04:23:36] <Dave911> Might have buy a machine?
[04:23:55] <Dave911> SWPadnos I think mentioned that the other day ....
[04:24:38] <Dave911> Have you been using your Mori Jr much?
[04:25:44] <cradek> not too much lately. no projects happening right this second.
[04:26:24] <cradek> and always something else to do - today was truck maintenance again - no machining required
[04:26:39] <Dave911> In one of your pictures regarding your Mori ... I think I saw a big motorhome ... do you still have that? Is that the truck?
[04:27:13] <cradek> yeah that's the bus - it's currently not at all broken :-)
[04:27:39] <Dave911> Is that a school type bus or ?? I forgot other than it was big.. ;-)
[04:27:42] <cradek> today was bronco maintenance - simple but a pain in the butt - when it rains it doesn't run
[04:28:00] <Dave911> So it is a fair weather truck.. :-)
[04:28:05] <cradek> yeah it's a blue bird, same size/shape they use for school buses
[04:28:25] <Dave911> Do you use that for camping etc?
[04:28:26] <cradek> (this one wasn't ever a passenger bus - it was a special mobile classroom/office thingy)
[04:28:29] <cradek> yes
[04:28:32] <cradek> it's awesome
[04:28:37] <Dave911> Nice ...
[04:28:51] <Dave911> What kind of MPG does that get ...
[04:28:53] <cradek> drove it to emc fest in kansas...
[04:29:05] <cradek> not bad, 7-8 highway (diesel)
[04:29:10] <cradek> pretty good for a HOUSE
[04:29:17] <Dave911> That is not bad at all..
[04:29:35] <Dave911> Do you know what engine it has in it?
[04:29:57] <cradek> a cummins straight 6 heavy duty something-or-other
[04:30:09] <Dave911> Wow, very nice....
[04:30:34] <Dave911> Did you sell that car that Jymmm was chatting with you about?
[04:30:51] <cradek> yep it's sold, but he hasn't picked it up yet
[04:31:02] <Jymmm> cradek: bastard!
[04:31:10] <Dave911> cool.. that seems like that happened quick ...
[04:31:30] <cradek> yep it sold itself - the guy was looking for a car as old as he is - he really likes it
[04:31:45] <Dave911> sorry Jymmm didn't mean to bring up a sore subject ...
[04:31:51] <cradek> haha
[04:31:55] <Jymmm> Dave911: LOL, it's all good =)
[04:32:12] <Dave911> Jymmm... aren't you in CA .. I thought you weren't allowed to have old cars ... ;-)
[04:32:18] <Jymmm> I'll just get a fiberglass body kit instead.
[04:32:30] <cradek> Dave911: lots of bus pictures here:
http://geektrap.com/bill/01205761106
[04:32:31] <Jymmm> Oh sure we are, there's just none here.
[04:33:01] <Dave911> Thanks for the picts link....
[04:33:27] <Jymmm> When you transfer a 34+ yo car, you have to get it smoged ONCE, it'll fail, then you take it to the Ref, then it's exempt forever after that.
[04:35:03] <Dave911> So the car can fail the smog test and still pass?? Wierd ...
[04:35:20] <Dave911> cradek: REALLY nice bus :-)
[04:35:31] <cradek> thanks
[04:35:45] <pfred1> Dave911 whats stranger is the persistant belief that manufacturing new vehicles has no environmental impact
[04:35:54] <Jymmm> Dave911: No, it fails. Jsut will get EXMPTED by a Ref.
[04:36:45] <Dave911> Jymmm... I get it but you would think that it would have to fail being older and you could just go straight to the ref..
[04:37:02] <Dave911> pfred1: True... crazy but true
[04:38:13] <Jymmm> Dave911: maybe you can, I don't know.
[04:38:53] <Dave911> Ok .. government stuff is a strange and mysterious thing oftentimes ..
[04:39:07] <Jymmm> Dave911: Damn cradek sold my car damnit!
[04:39:13] <Jymmm> ;)
[04:39:33] <cradek> Jymmm: you're too young to know how to drive it anyway
[04:39:54] <Dave911> Yeah... but personally I would have gone after his bus :-) but it probably is not for sale for any worldly price
[04:40:17] <Jymmm> cradek: You put the crank in the front of the bumper, turn on the ignition, and crank that sucker!
[04:40:27] <cradek> heh, not QUITE that old
[04:40:41] <Dave911> What was it you sold again??
[04:40:48] <cradek> 52 chevy
[04:40:59] <Dave911> Oh yeah..
[04:41:23] <Dave911> I have a 62 Thunderbird I need to fix up or sell... amongst others...
[04:41:30] <Dave911> Too many projects
[04:41:37] <Dave911> Too little time
[04:41:50] <Jymmm> Dave911: Yeah, cradek wused out on me when I told him I wanted to shave the top =)
[04:42:10] <Dave911> I remember ....
[04:42:11] <cradek> this guy wants to restore it to original and drive it
[04:42:24] <Jymmm> oh, I'd drive it!
[04:42:40] <cradek> I have awesome 3" wide whitewalls on it
[04:42:48] <Jymmm> and stick spark plugs in the tail pipe too!
[04:43:08] <Dave911> You CA guys like to modify our nice clean old cars ...... ;-)
[04:43:27] <Jymmm> Dave911: You had the right word.... OLD
[04:44:11] <Jymmm> I already know someone in LA that would do the paint job too.
[04:44:35] <Jymmm> which is 400 miles away
[04:44:49] <Dave911> Are you south of LA?
[04:45:01] <Jymmm> That would be Mexico =)
[04:45:09] <Jymmm> No, I'm near San Francisco
[04:45:14] <Dave911> Well that is south .... :-)
[04:45:42] <Dave911> OK ..
[04:46:15] <Dave911> I'm in Indiana... home of corn and soybeans ...
[04:46:28] <Jymmm> you poor bastard!
[04:46:40] <Dave911> You gotta live somewhere ...
[04:46:53] <Jymmm> Isn't that Tornado Alley area?
[04:47:26] <Dave911> Yes .... tornadoes come through here quite a bit ... but not as bad as Kansas and Oklahoma
[04:47:55] <Dave911> Still one went over my house once and touched down east of me about a mile and tore down a factory and some houses ...
[04:48:01] <Jymmm> Yeah, I'll stick with our Earthquakes
[04:48:47] <Dave911> I dunno.. earthquakes seem a lot worse
[04:49:41] <Dave911> Fortunately we have the 4 seasons out here ... ice and snow, wet and sloppy, road repair, and get ready for ice and snow....
[04:50:06] <Jymmm> lol, like I said... You poor bastard!
[04:50:34] <pfred1> Dave911 well at least the place isn't filled up with Californians
[04:50:36] <cradek> indiana sucks because it has a low speed limit (guess how I know this)
[04:50:52] <Jymmm> cradek: Traffic School you had to attend?
[04:51:02] <Dave911> hey .. we think that 65 is really fast!
[04:51:07] <cradek> a nice gentleman explained it to me when I was flying through there at warp 3
[04:51:22] <Jymmm> cradek: How nice?
[04:51:26] <cradek> at least it's small east-to-west
[04:51:27] <pfred1> 65 is our fastest speed limit
[04:51:53] <cradek> NE, IA are 75 but they're each 450 fucking miles across
[04:52:07] <pfred1> but our back roads are all 50 MPH too
[04:52:14] <Dave911> Indiana cops keep our taxes low.. ;-) Thanks cradek
[04:52:19] <cradek> heh
[04:52:32] <cradek> actually he gave me a warning - he was very nice.
[04:53:02] <Dave911> That was nice ...
[04:53:19] <Dave911> NE is way too wide
[04:53:36] <cradek> yep if I go west, 400 miles of NE - if I go east, 400 miles of IA
[04:53:47] <cradek> gets old
[04:53:49] <cradek> at least it's fast
[04:54:40] <Dave911> I've driven to WY a few times and NE takes forever to get through.. Other than Cabela's there is no place I want to stop at along I-80.
[04:57:10] <Dave911> cradek: Have you tried Les' jog enabled during a tool change - tool change py script?
[04:57:39] <cradek> no, I have no need for that
[04:58:04] <cradek> (sounds like it just does the run-from-line that you can get with a single right click, anyway)
[04:58:24] <Dave911> I think you are right ..
[04:58:56] <Dave911> What do you do on your lathe when you get swarf bound up around your bit ... just pause, clean and continue ??
[04:59:27] <Dave911> Or is that not generally an issue
[04:59:29] <cradek> pause (or turn maxvel down to zero), turn spindle override down to zero, clean up, spindle back up, resume
[04:59:47] <cradek> I don't think jogging is usually necessary
[05:00:49] <cradek> I get it more with drilling deep holes in stringy material - but I just pause it when it's up in a peck - SO 0%, clean up, SO 100%, resume
[05:01:23] <Dave911> generally probably not.. but I have worked on one job where swarf was a real problem and I sure would have liked to have been able to do that .... but if you break an insert ... well then I guess you need to stop, change tool and then resume from the appropriate line anyway ..
[05:01:41] <cradek> yes
[05:02:05] <cradek> I seem to do a lot of resuming at (right before) tool change
[05:02:32] <Dave911> Does that usually work if you don't have any O loops around?
[05:02:39] <cradek> sure, it works fine
[05:02:48] <cradek> I do it all the time
[05:03:46] <Dave911> OK... then I am lost as to what Steve's issue is ... I know what cam software he uses and it doesn't make O subs etc .. loops was incorrect although they could be I suppose ..
[05:04:49] <cradek> he wants pause - jog - mdi/touch off - cycle start to resume by feeding to the point where he paused
[05:05:14] <cradek> instead we have abort - jog - mdi/touch off - select appropriate line, right click, run from here
[05:05:32] <cradek> he thinks that is an important and unacceptable difference
[05:06:09] <Dave911> So we need to relabel a key for him so the abort is the pause key?? ;-)
[05:06:28] <cradek> you go ahead and suggest that, see where it gets you...
[05:06:49] <Dave911> you know what that will get me .. :-)
[05:07:25] <Dave911> I'll be the head of the EMC2 nanny state.. ;-)
[05:07:34] <cradek> haha
[05:09:01] <Dave911> I don't care ... I'll suggest that anyway .....all he can do is throw rocks and I am on the other side of a big pond :-)
[05:10:14] <pfred1> you could call it Pause/Abort
[05:10:43] <Dave911> "PA" for short..
[05:11:14] <pfred1> better still ||
[05:11:26] <Dave911> Really from a results stand point I just don't see the issue any longer
[05:12:41] <Dave911> Oh well ... better sign off for the nite ... good nite guys ...
[05:13:12] <EricKeller> good night, john-boy
[05:15:28] <cradek> hm, why am I still awake?
[05:16:00] <EricKeller> because the Waltons reference didn't set off a long string of "good night ...."
[06:58:39] <genehacker> newb question, so basically I've found a large expensive stepper controller that can be controlled with EMC, perhaps via parallel port
[06:59:23] <genehacker> I can just use EMC to send signals to it to drive it, correct?
[07:00:05] <celeron55> if it has a step/dir input, yes
[07:01:50] <genehacker> yes it does
[07:02:06] <genehacker> in fact is even more
[07:02:25] <genehacker> *it even has more
[07:02:56] <genehacker> so I just find a way to hook it up to a parallel port and I'm set?
[07:06:31] <genehacker> actually I don't know if it hooks up to parallel port
[07:06:42] <genehacker> it has some weird 50 pin connector on it
[07:07:21] <celeron55> you just have to wire the step and direction signals to a parallel port (assuming it accepts 5V with little current capacity)
[07:08:55] <genehacker> seriously it's that easy? I don't have to solder something complex up in between?
[07:09:13] <celeron55> if it has opto isolated inputs needing more current for example, you might need a buffer in between
[07:10:49] <celeron55> well, you should look up from a datasheet what you need to do to drive it in using those step/dir signals
[07:11:17] <celeron55> maybe there is also an enable pin or something, who knows
[07:12:08] <genehacker> I think there is some sort of enable pin
[07:12:28] <Dave911> logger_emc: bookmark

[12:16:27] <Dave911> Hi JT-Dev
[12:16:45] <JT-Dev> morning did you figure out the FO?
[12:16:57] <Dave911> Not yet ..
[12:17:12] <Dave911> How does that work?
[12:17:36] <JT-Dev> I have a rotary binary switch on the Hardinge that has 4 outputs
[12:17:56] <Dave911> oh..... to a mux
[12:17:58] <JT-Dev> I pipe that into the mux16 in dev
[12:18:16] <JT-Dev> then into the direct input for halui.feedoverride
[12:19:01] <JT-Dev> I had to wire my switch to give me an output for 0 to keep the number from the mux from bouncing between contacts
[12:19:38] <Dave911> OK ... that makes sense ..
[12:19:41] <JT-Dev> works really sweet... it does override the GUI slider but that is what I wanted
[12:20:40] <Dave911> I'll have to look at the mux16 I guess ...
[12:20:57] <JT-Dev> its in dev
[12:21:20] <JT-Dev> do you have an application for it?
[12:21:27] <Dave911> Is there a way to do this with a pot to an analog value to a override ? its in dev > no problem I can get that ..
[12:21:35] <Dave911> Lathe ..
[12:21:52] <Dave911> I just like the idea of grabbing a knob
[12:22:29] <Dave911> Seems a lot more natural
[12:22:33] <JT-Dev> if you can get a number from your pot yes...
[12:22:45] <JT-Dev> I agree
[12:23:06] <JT-Dev> I like to scan the panel and see the position of the knob and know that my fo matches it
[12:23:33] <Dave911> I do have a PLC connected so I could run a pot into an analog input
[12:24:04] <JT-Dev> then if you can get 4 outputs to give you binary your set
[12:24:18] <Dave911> Yep. For some things knobs are simply better .. FO is one of them
[12:24:34] <JT-Dev> what kind of plc is it?
[12:24:54] <Dave911> I could do the analog to digital in the PLC and send it over via Modbus
[12:25:31] <Dave911> Actually I might have enough DIs available to do it directly and skip the analog
[12:25:53] <JT-Dev> DIs?
[12:26:14] <Dave911> So you do the same for your spindle override also .... DI's - sorry Digital inputs
[12:27:03] <JT-Dev> ah ok
[12:27:12] <JT-Dev> yes and max vel
[12:27:44] <Dave911> Oh...... max vel is a very good idea ...
[12:27:48] <JT-Dev> I don't have any switches for SO and MV
[12:27:54] <JT-Dev> but wish I did
[12:28:13] <Dave911> Was that 4 bit output switch expensive?
[12:28:31] <JT-Dev> it came on the lathe
[12:28:43] <Dave911> That was handy :-)
[12:29:05] <JT-Dev> I wish I knew where to get some more
[12:29:56] <Dave911> I think that Digikey and similar sell them .... Just like a pot but with 4-5 terminals on the back ??
[12:30:28] <Dave911> Probably not cheap though..
[12:31:03] <JT-Dev> well I'm off to work now talk to you later
[12:31:06] <Dave911> Hard to beat a pot for low cost ..
[12:31:18] <Dave911> OK... Thanks!
[13:19:06] <JT-Work> Dave911: you still around?
[13:19:37] <Dave911> Yep... still here :-)
[13:20:32] <JT-Work> I wonder why you can't hack up a usb gamepad and replace the sticks with pots and using input you have 4 analog to digital inputs that don't use any I/O
[13:20:53] <JT-Work> and you have all those buttons that you could connect to switches
[13:21:52] <JT-Work> I looked at mine just before I left and the sticks give a -1 to 0 to 1 float input
[13:23:17] <Dave911> That would probably work. Have you seen the Pokeys device? I think something like that would work also. But I have never used the USB HID (SP?) interface. Does all of the I/O show up as Pins?
[13:26:47] <Dave911> Pokeys device: --->
http://www.cnc4pc.com/Store/osc/product_info.php?cPath=54&products_id=214
[13:27:50] <JT-Work> on the gamepad yes all the buttons show up as pins
[13:28:30] <JT-Work> the pokey thing looks good... has anyone used it with EMC?
[13:29:10] <JT-Work> * JT-Work reads on and it is like a keyboard
[13:29:27] <Dave911> I thought I saw someone mention it once a while ago ..... on the IRC I think...
[13:30:12] <Dave911> If all of the I/O shows up as pins that might be really easy to interface :-)
[13:30:45] <JT-Work> might be a better solution than wacking up a gamepad just depends on how the pins show up I guess
[13:30:51] <Dave911> I think there are other devices out there like that also that are used for PC based arcade games
[13:31:51] <Dave911> It would be cheaper than buying an analog card for the PLC I am using (unless I already have one ... might need to check.. )
[13:33:39] <Dave911> Good idea though - using USB for a pot interface Do you use a gamepad for your plasma table to jog?
[13:34:00] <JT-Work> yes
[13:34:14] <Dave911> Did I see you mention that your plasma table is out of commision?
[13:34:24] <JT-Work> it's much easier to see what I'm doing with the gamepad
[13:34:41] <Dave911> What kind of game pad do you use...
[13:34:49] <JT-Work> it was for a short while ... I stole the 5i20 out of it for the Hardinge
[13:35:25] <Dave911> ha ha ... that happens
[13:35:29] <JT-Work> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Simple_Remote_Pendant
[13:36:39] <JT-Work> looks like the pokey can be configured to do what you want with the I/O
[13:36:54] <Dave911> Cool you did that page .. thanks!
[13:37:00] <JT-Work> yea
[13:38:39] <Dave911> I have heard of guys using gear from this company also for CNC conversions but I have no experience with their equipment ->
http://www.xkeys.com/custom.php
[13:38:49] <JT-Work> you can have a matrix keyboard with pokey cool
[13:39:56] <Dave911> yes ... the guy who runs the company that makes Pokeys has been actively developing that product for the last few years .. he has come a long ways.. They have a interface for Mach3 also ..
[13:47:52] <Dave911> Found a game pad .. unfortunately Playstations pads are not USB ... probably need to do some shopping ;-) Or perhaps just buy one of those Pokeys devices and give it a shot. I have another project coming up where I could use that ..for overrides etc
[13:48:54] <Dave911> Oh .. better keep looking I remember I bought a USB one a while ago for flight simulator :-)
[13:49:11] <Dave911> bbl
[13:49:19] <JT-Work> I'm ordering a pokey atm
[13:50:56] <cnc> i loaded the latest ubuntu cd with 2.3.5 last nite,and then got the 2.4 update
[13:51:05] <JT-Work> great
[13:51:27] <cnc> but my axis window still shows 2.3.5
[13:51:44] <JT-Work> how did you update to 2.4?
[13:52:15] <cnc> update manager at top of screen
[13:52:34] <JT-Work> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?UpdatingTo2.4
[13:52:49] <JT-Work> did you follow the above?
[13:55:56] <JT-Work> * JT-Work must boot this windoz machine now
[14:01:35] <cnc> doing it right now
[14:58:07] <EbiDK_> EbiDK_ is now known as EbiDK
[16:23:53] <Jymmm> Morning
[16:30:16] <micges> hi
[17:31:20] <andypugh> How much do you trust your programming?
http://www.youtube.com/watch?v=yln_IGDuOCo
[17:33:50] <frallzor> I knew it was a bad idea to mill a too thin piece of wood :P
[17:33:54] <frallzor> it flexes! =D
[17:42:16] <micges> andypugh: I wouldn't sit on that chair :P
[18:00:59] <frallzor> hah i though the machine was losing steps
[18:01:43] <frallzor> and then looking at the machined part it suddenly "was gone" and then I realized when touching it, its flexing like even more crazy than I imagined :P
[18:31:17] <frallzor> steel wool is nice on wood to get rid of burrs, id you didnt know =)
[18:54:56] <i_tarzan> more than filing, planing?
[18:55:15] <JT-Work> gotta make sure the wood don't rust after you use it :P
[19:14:30] <grommit> I have a very basic gcode question. How do you set a new zero point for a fixture offset? I started homed. I move the xyz to say: X2 Y1 Z-2. From the menu if I select Machine->Zero coordinate system-> P2 G55 nothing changes. If I issue MDI command G55 x0 y0 z0 it is the same as g53 x0 y0 z0 (goes home). Also, if I edit emc.var file and plug in 2,1, and -2 into 5241,5242,and 5243 and restart EMC these just get set back to 0. What am I missing?
[19:17:33] <cradek> grommit: select the axis you want to zero, poke touch off, [enter zero which is the default], click ok
[19:21:55] <grommit> Ah, I see. I can select, say G55, from the touch off screen. I also see that Machine->Zero Coordinate System does just that, zero's that coordinate system. Duh. Ok, thanks!
[19:23:42] <grommit> I would be nice if when you were at a given position, there was a way one could touch off all axis at once (to 0.0).
[19:23:49] <grommit> I==It
[19:26:49] <grommit> Also, why is it that if I edit emc.var it gets reset to zero? Shouldn't editting that file have the same effect as touch-off?
[19:27:05] <SWPadnos> noy while EMC is running
[19:27:07] <SWPadnos> not
[19:27:08] <cradek> don't hand edit the var file with emc running
[19:27:15] <cradek> don't hand edit the var file
[19:27:22] <SWPadnos> just don't :)
[19:27:26] <cradek> if you want to set a var directly, use #1111=111
[19:27:30] <cradek> (mdi)
[19:27:49] <cradek> but that's very rarely what you want
[19:28:01] <cradek> G10, G92, G28.1, etc are better ways to affect variables
[19:30:29] <grommit> I see, editting while emc was running was my problem. It works as advertised if I edit first.
[19:31:17] <grommit> Actually as advertised says: "You can also set these values by editing the VAR file itself and then issuing a [reset] so that the EMC reads the new values." <-
http://www.linuxcnc.org/docs/devel/html/gcode_coordinates.html#cha:Coordinate-System (perhaps this needs fixed?)
[19:32:53] <SWPadnos> that page doesn't eaxctly say what "issuing a [reset]" means, does it?
[19:33:01] <SWPadnos> (not helpful on that score)
[19:33:22] <grommit> True if you want to get technical on my ;-)
[19:33:29] <grommit> my==me
[19:33:47] <SWPadnos> oh, not so much your fault, it just doesn't say, even in the pseudo-step-by-step instructions
[19:35:15] <frallzor> * frallzor gots his hands on some big pieces of wood today! yummy
[19:36:43] <grommit> btw, is there a way to reset EMC vs quit/restart? It gets kind of annoying having to keep quitting and restarting when you are tweaking things. Seems like I ought to be able to HUP it or something...
[19:37:24] <cradek> what do you mean by reset
[19:37:36] <SWPadnos> no, there's no "pretend I restarted you now" function
[19:37:37] <grommit> cuase it to reread all it's config files
[19:37:44] <cradek> no
[19:38:28] <grommit> feature request? Is there something unique that makes that difficult?
[19:38:39] <SWPadnos> it's not completely possible to do that, since the realtime system also would need to be restarted (in case you changed a thread period), which makes it a little more complicated
[19:39:28] <SWPadnos> for some set of configuration information, it's possible to do
[19:39:41] <micges> SWPadnos: realtime part is adpative to thread period changes
[19:39:58] <SWPadnos> since when?
[19:40:08] <micges> I mean emcmot part
[19:40:30] <grommit> Might be nice to have a reset for those things...(I am assuming of course that they are all the things I want :-)
[19:40:49] <SWPadnos> RTAPI chooses a base period (or whatever the fastest period is), and then makes everything else a multiple of that
[19:40:59] <SWPadnos> once loaded, RTAPI will not change that base period
[19:41:14] <SWPadnos> additionally, there is no way to actually remove threads, even if you don't want them any more
[19:42:12] <SWPadnos> individual HAL components aren't as much of an issue since you can just remove all the modules and reload them as necessary, but the underlying RTAPI stuff can be problematic
[19:42:17] <micges> SWPadnos: yes you're right, I was thinking only on emcmot part
[19:43:28] <SWPadnos> oh hmm. bbl
[20:07:18] <sealive> is there a tiimeline for 10.04 release
[20:08:33] <micges> sealive: work is in progress
[20:08:43] <sealive> :D
[20:08:43] <cradek> no, we never have timelines. we sometimes have guesses, but usually they are wrong.
[20:09:29] <sealive> lucid does not have python 2.5 anymore
[20:10:10] <sealive> i shout my python 2.5 so i got 9 errors on synaptic on karmic
[20:10:34] <sealive> apt-get uses also python2.5
[20:12:18] <sealive> ok good night all
[20:14:09] <andypugh> Does EMC2 work on 10.4, assuming a suitably patched kernel, or are there "issues"?
[20:17:58] <mozmck_work> andypugh: no issues that I've found yet, but I haven't run it through any rigorous testing yet.
[21:00:50] <Dave911> I somehow broke the tool editor in the 2.4.0 release. DGAR who wrote the script for the editor pointed me to a newer version last week, so I copied the new version over the old version and now the editor window doesn't even pop up. He had two newer versions and I tried both. I even tried copying the newer version over the older in the source code directory and then recompiled everything....
[21:00:52] <Dave911> ... Still no go. Anyone else having problems with the tool editor? The original version left zombie copies of tooledit in memory after exiting the software. I'm not sure what to do next.
[21:02:27] <Dave911> Perhaps the tooleditor in the current Git master is ok ???
[21:03:35] <SWPadnos> did you make sure that the copied files were executable?
[21:03:43] <Dave911> Yes .
[21:03:45] <SWPadnos> chmod a+x maybe
[21:03:57] <SWPadnos> hmmm, then no ideas that don't need more information :)
[21:04:08] <Dave911> With the gui - right click properties etc
[21:04:22] <SWPadnos> do you get any information if you run emc in a terminal?
[21:04:41] <SWPadnos> which +x bits did you set? user/group./others?
[21:05:00] <SWPadnos> (I don't know which actually need to be set - you would need to look at other scripts in that dir)
[21:05:33] <Dave911> Um.. didn't try that ... let me see ..... but this is after I think it is set as read only and executable.. that is the way it was set after the compile and install also ..
[21:05:54] <SWPadnos> well, like I said, there are 3 different executable bits
[21:06:26] <Dave911> I copied the modified tcl script into the source and then compiled emc so it would install it properly .. no difference
[21:06:49] <Dave911> And no compile/install errors .. let me run it from the cmd line
[21:06:55] <SWPadnos> oh hmm. in that case terminal output might be necessary
[21:07:03] <SWPadnos> if there is any
[21:07:37] <Jymmm> .
[21:08:19] <Dave911> Computer is booting ...
[21:08:36] <SWPadnos> ok. I'll go refresh my coffee :)
[21:08:39] <Dave911> I'm thinking I am doing something stupid since no one else is complaining about this ...
[21:10:37] <Dave911> No errors at the command prompt ..
[21:11:02] <Jymmm> Dave911: Like stick your finger in the light socket while standing in a puddle of water?
[21:11:44] <Dave911> Jymmm.... will that make an error show up ... ??? ;-)
[21:12:05] <Jymmm> Dave911: Only one wayt to find out =)
[21:12:13] <SWPadnos> Dave911, using AXIS?
[21:12:25] <Dave911> yes
[21:12:49] <Dave911> I tried to run the script at the command prompt via tooledit.tcl and I get an error from bash ??
[21:13:23] <Dave911> I think I did a ./tooledit.tcl ( tooltable name)
[21:13:42] <Dave911> I copied the tooledit.tcl script into the config directory
[21:13:55] <SWPadnos> have you loaded a tool table?
[21:14:13] <SWPadnos> (within axis)
[21:14:16] <Dave911> I thought it was loaded automatically when I start the config ?
[21:14:20] <SWPadnos> hmm
[21:14:35] <SWPadnos> yes indeed. does that file exist?
[21:14:38] <Dave911> Pretty sure it does .. actually I know it does
[21:14:46] <SWPadnos> [EMCIO]TOOL_TABLE
[21:14:51] <Dave911> Yes .. and I can edit it with gedit etc
[21:15:20] <Dave911> If I run a program and the tool is not in there Axis complains .. I add the tool Axis is ok etc
[21:15:32] <Dave911> So axis is ok with the tool table ....
[21:16:26] <Dave911> But tooledit (the new one from DGAR) simply doesn't fly for some reason ... perhaps it is simply a non working program ?? Seems unlikely
[21:16:44] <SWPadnos> ok, so you could edit the tool table with stock 2.4, but not any time after copying a newer version of the tool table editor?
[21:16:55] <Dave911> right ..
[21:17:13] <Dave911> But I also get no errors ... but perhaps that is normal?
[21:17:26] <SWPadnos> just for grins, you could try reinstalling emc2 with dpkg/synaptic/apt
[21:17:47] <SWPadnos> that should replace the file with the packaged one
[21:17:50] <Dave911> Does anyone have a copy of tooledit that doesn't leave zombies ?
[21:18:10] <SWPadnos> I don't know, but you're talking about two different problems
[21:18:24] <Dave911> I could do a Git update into my emc2-dev directory also and get the latest master
[21:18:47] <SWPadnos> did you install the package or compile/install (or RIP)?
[21:18:50] <Dave911> The original 2.4 release version leaves a zombie copy of tooledit after an edit session
[21:19:06] <Dave911> It is installed . not run in place
[21:19:29] <Dave911> The copy of tooledit DGAR pointed me to is suppose to get rid of the zombie situation
[21:20:09] <SWPadnos> first things first
[21:20:10] <Dave911> I can do a git update and see if it was update on the master .. I thought that this would be a more popular problem ;-)
[21:21:10] <Dave911> Well ok... I'll do the git update and find the last file put into the master and try that out ...
[21:21:14] <SWPadnos> updates to your RIP source have nothing to do with the installed packages
[21:21:42] <SWPadnos> I'd suggest making sure the installed version works first (even if it leaves zombies)
[21:21:52] <SWPadnos> then try to get the RIP version to work the same way
[21:21:58] <Dave911> I know but I can get the tcl script out of the rip update and then copy that into the install directory
[21:22:05] <SWPadnos> then try to get the RIP version to work with the modified version
[21:22:19] <Dave911> I get it .. good idea.. perhaps this only happens in installed copies ??
[21:22:43] <SWPadnos> no idea, you're the one with the tools to find out :)
[21:23:29] <Dave911> OK ... hoping someone already fixed this issue .. but I will figure this out and report back .. :-) Thanks!
[21:24:18] <SWPadnos> I'm not a definitive source on the subject, so feel free to get other answers before doing any real work
[21:25:26] <Dave911> NP .... I think doing what you suggested will nail down whether it is my error or a program problem .. I already have git on this computer and a RIP setup so it is no big deal to do what you suggest ..
[21:25:43] <Dave911> I can't think of anything else myself .... to try
[21:27:24] <Dave911> I was chatting with cradek last night .. and I was about to post something on the email list about the jog under pause/tool change but I see that a lot has been added since then !!! Wow ... John K. wrote a nice addition that I think added a lot of perspective to the situation .... seems like a real can of worms
[21:27:54] <SWPadnos> yes indeed
[21:28:45] <Dave911> Just seems like no clear solution to that ... The more I thought about it, the more pitfalls came to mind ...
[21:28:46] <SWPadnos> there are several feature requests outstanding (like backing up for EDM stuff), and there are potential changes we can make that could facilitate both those features plus more
[21:29:30] <SWPadnos> yes. it's relatively easy to fix for a small subset of machines that EMC2 currently supports, but I prefer more widely applicable fixes/additions
[21:29:35] <Dave911> Hmm backing up for EDM .. that does have a lot of similarities to an extent
[21:30:16] <Dave911> I agree, I have a hard time seeing how any one solution can be made generic
[21:30:43] <SWPadnos> yes. I think a fair amount of it hinges on addressing the difference between the interpreter state and the machine state. the interpreter can be waaaaaay far ahead of the machine
[21:31:31] <SWPadnos> and when you stop (pause / abort), the interpreter doesn't "rewind" to where it was when it placed the currently executing motion in the queue
[21:31:40] <SWPadnos> and it can't, without some fundamental changes
[21:32:12] <SWPadnos> also, since paused is still "RUN" state to the motion controller, you can't use MDI or MANUAL commands in that state, it's specifically prohibited
[21:32:20] <Dave911> Seems like at some point it makes sense to simply dump everything and then dry cycle back to the stopping point as you mentioned (I think ..???))
[21:32:21] <SWPadnos> so we may need to add another state, or something like that
[21:32:56] <SWPadnos> sure, but what happens to variables, coordinate systems, offsets, etc. that may have been changed in the code that's been interpreted but not yet executed?
[21:33:08] <SWPadnos> you need to unwind those too
[21:33:54] <Dave911> What if you just dump all of that and dry run it up to the same point?
[21:34:05] <SWPadnos> you still haven't reset things like G92
[21:34:14] <SWPadnos> or #variables that have been changed
[21:34:46] <Dave911> Oh .. geez... That would have to be remembered also ... didn't think about that .... big can of worms
[21:34:56] <SWPadnos> nightcrawlers
[21:35:11] <SWPadnos> gotta run. see you later. good luck with the tool table editor
[21:35:28] <Dave911> At some point a baseline has to be established and you have to be able to get back to that spot .. otherwise nothing will be repeatable
[21:35:37] <Dave911> Thanks ..
[21:41:58] <Jymmm> I wonder if it's worth $95

[21:45:38] <Jymmm> SWPadnos: ^^^^^
[21:46:58] <cradek> if you need one, and you want that model, it's probably a fine price
[21:47:02] <archivist> Jymmm, I have one of those, for accuracy not much better than the cheap ones, for usability yes far better
[21:47:45] <archivist> they dont auto switch off, very important for hand lathe work
[21:47:55] <Jymmm> Thanks guys. I have dial, just not digital.
[21:48:00] <Jymmm> archivist: OH, good to know.
[21:48:29] <archivist> losing ones offset on the cheap sh1t is a pain
[21:48:34] <andypugh> I am sure they are cheaper than that?
[21:48:51] <archivist> I payed about £60 iirc
[21:49:04] <Jymmm> What I want is a digital DTI that I can output to EMC to "touch Off"
[21:49:54] <DaViruz> i've had my digital mitutoyo calipers for about 3 years now and i have never ever had to reset the origin
[21:50:27] <DaViruz> also it's a more modern version then the one above, and i think i paid about the same (in a store)
[21:50:33] <andypugh> Yeah, £55 is not normally $95. In fact for tools $95 is normally £110.

[21:52:27] <DaViruz> i knew hp would kill us all
[21:53:43] <andypugh> That phrase reminded me of:

[21:54:21] <Jymmm> LOL
[21:54:58] <Jymmm> But, WHICH is the lil bastard is what I'd like to know =)
[22:06:04] <andypugh> But, anyway, back to touch-off. I have wondered if one of these would be better for that? (The vernier-shaped calipers get in their own way rather a lot).

[22:06:56] <cradek> I don't see how you'd use that for touch off?
[22:09:41] <andypugh> Well, you would need the internal version, which I couldn't find.
[22:10:02] <cradek> isn't it just as easy to use any old dowel pin?
[22:10:27] <cradek> anything that telescopes will have cosine error - something round doesn't
[22:10:53] <andypugh> If you have proper jog-wheels, yes. If you have a game-pad....
[22:11:15] <andypugh> These little things are almost (but not) right.

[22:11:47] <cradek> yikes, you can get two jogwheels for that money
[22:13:51] <andypugh> Well, there is that...
[22:14:03] <archivist> what I use is
http://www.measureshop.biz/en/measuring-instruments/dial-bore-and-depth-gauges/centring-devices/diacator-centring-devices.html
[22:14:33] <archivist> I did not pay that price though!
[22:14:51] <cradek> wait what task are you talking about? I thought you were talking about zeroing a height
[22:16:12] <tvc_> Anyone know of any examples for setting up a stepgen in velocity mode?
[22:16:16] <andypugh> We were, but I think Archivist just wanted a gloat.
[22:16:51] <cradek> there are no ready-to-use sample configs for that
[22:17:01] <pjm> tvc_ i use velocity mode control with my 7i43, i can send u the config if u want to look at it
[22:17:15] <tvc_> please :)
[22:17:15] <andypugh> Somebody here pastebinned a HAL within the last few weeks that used it
[22:18:28] <andypugh> Though the Hostmot2 stepgen has a full-time velocity input pin, and the software one only grows that pin when configured with a "v" in the loadrt line.
[22:20:13] <MarkusBec> MarkusBec is now known as MarkusBec_away
[22:22:01] <cnc> anyone know if you can set tool table lengths thru touchoff,using 2.3.5
[22:23:56] <andypugh> tvc_: You need something like loadrt stepgen step_type=0,0,0,0 ctrl_type="p,p,p,v"
[22:24:09] <andypugh> cnc: Yes.
[22:24:24] <tvc_> Andy I managed that far :)
[22:25:02] <tvc_> getting lost w/ some scale bit, can't find a good reference and I'm really not to sure exactly what it is used for...
[22:25:24] <andypugh> cnc: Actually, I am not sure.
[22:26:22] <tvc_> When I try to run it EMC tells me " 'scale.0.in' does not exist "
[22:26:39] <cnc> andypugh:I thought it was in the changelog,but cant find anything else
[22:26:55] <andypugh> It is definitely there in 2.4
[22:27:16] <andypugh> But in this 2.3.5 VM I have it isn't there.
[22:27:50] <andypugh> Yes it is.
[22:28:20] <cnc> where?
[22:28:22] <andypugh> You need to be touching off with Z selected, and then T for Tool Table is at the bottom of the drop-down for coordinate system
[22:28:58] <cnc> lemmee try that,didnt see it earlier
[22:29:29] <andypugh> tvc_ Do you have a line "loadrt scale" and an "addf scale servo-thread" ?
[22:30:27] <andypugh> cnc: You also need to have a tool loaded...
[22:31:06] <tvc_> Thanks again andypugh ;)
[22:32:53] <cnc> andypugh:thats what it was,didnt have a tool loaded,thanks
[22:36:53] <andypugh> cradek: Very cheap jog-wheel:

[22:45:47] <tvc_> Seems to be up and working fine, need to cal the speed in, should be no biggy... onto the next question... :)
[22:47:14] <andypugh> SheetCAM is nothing like as pretty as Freemill, but it does seem a lot more useful...
[22:47:44] <andypugh> Though I guess that depends on what you are doing.
[22:52:29] <martin___> martin___ is now known as martinst
[22:58:45] <pfred1> I slam dunked that driver
[23:00:40] <andypugh> In a good way, or a bad way?
[23:00:57] <pfred1> andypugh it worked right off hows your driver coming along?
[23:01:11] <pfred1> for me the third time was a charm ;)
[23:01:25] <andypugh> Half the components haven't blown up. (All the cheap ones)
[23:01:45] <pfred1> cheap stuff is tough
[23:02:25] <pfred1> now i just have to check the step input draw to see if I need to make a booster of sorts for it or not
[23:02:40] <pfred1> and if i don't then I'm done with the electronics!
[23:04:42] <andypugh> I saw this and thought of you....
http://www.seeedstudio.com/wiki/index.php?title=Stepper_Motor_Driver_v2.3
[23:05:36] <pfred1> thats out of the rep rap project isn't it?
[23:06:04] <pfred1> it has to be with the RJ-45 connectors
[23:06:25] <pfred1> remember it does NOT support ethernet!
[23:10:04] <andypugh> I wondered what they were.
[23:10:24] <andypugh> Actually, there are quite a few fun things in the Seeed Pool.
[23:10:25] <pfred1> yeah they used them because they're cheap and easy to get
[23:10:31] <andypugh> http://www.seeedstudio.com/wiki/index.php?title=Open_source_PCBs
[23:10:42] <pfred1> personally I htink they're a poor connector choice but whatever
[23:11:40] <andypugh> I don't even like them for networking.
[23:11:46] <pfred1> heh
[23:11:55] <pfred1> they're Ok for that I guess
[23:12:26] <pfred1> really I'm trying to figure out why these boards need all the connectors they have on them
[23:12:29] <andypugh> Given a choice I like to use Lemo. But Speakons are very cheap and very good.
[23:12:53] <pfred1> yjrtr's 26 different connections on the thing!
[23:12:57] <pfred1> there's even
[23:13:46] <pfred1> I use barrier strips and I use a 10 screw one of those and the high power is redundant on it
[23:14:03] <pfred1> just coz i had one extra the way it all worked out
[23:14:24] <pfred1> which with the unipolar drivers i actually use
[23:14:50] <pfred1> but on the bipolar board I suppose you have your choice where you'd like to input the high volts
[23:15:27] <pfred1> and in use I won't even use the 5 volt output but it was handy in bench testing each driver
[23:18:50] <pfred1> hmmm that is borderline now isn't it?
[23:19:13] <pfred1> my ins draw 11.8 ma and the chip outs 24 ma and i have to gang 2 together
[23:19:45] <pfred1> I guess i should demultiplex that a little to spread the draw out
[23:20:00] <pfred1> but I don't wanna!
[23:20:12] <andypugh> Is that P-Port current?
[23:20:45] <eric_unterhausen> eric_unterhausen is now known as EricKeller
[23:21:16] <pfred1> no the port is connected to a 74AHCT245
[23:21:25] <pfred1> which can source or sink 24 ma
[23:21:54] <pfred1> now if i throw a small signal diode on it i drop to under 9 ma draw
[23:22:08] <andypugh> Swap for a 74AS245?
[23:22:10] <pfred1> hmmmm...
[23:22:26] <pfred1> easier to just throw another IC in there to spread it out
[23:22:39] <pfred1> even easier to throw the diode in there and call it a day :)
[23:22:58] <pfred1> its not like I don't have a bag of 1,000 of the little buggers
[23:23:51] <andypugh> There is no 74AS245 anyway. There is an AS244 which is 64mA sink.
[23:24:03] <pfred1> dang
[23:24:18] <pfred1> that is massive for an IC
[23:25:09] <pfred1> I'll bench test it with the diode hack see how it runs
[23:25:22] <andypugh> Just use a ULN2008, you know you want to.
[23:25:25] <pfred1> if it seems to run alright I think I'll go with it for a bit
[23:25:39] <pfred1> all i want to do is be done wit hthe electronics
[23:26:05] <pfred1> much as i like electronics I'm starting to dream about these motor drivers I been at it so long now
[23:26:43] <andypugh> I know the feeling, it was nice to be in the garage machining briefly this evening.
[23:26:59] <pfred1> yeah i had fun refurbishing my plane i bought over the weekend
[23:27:14] <pfred1> I cleaned it all up and put some homebrewed oils on it
[23:27:40] <andypugh> I am not sure I want to ask how you "homebrew" oil.
[23:27:46] <pfred1> I blended some tung linseed mineral and laquer thinners together and spread that all over it
[23:28:02] <pfred1> you have to nourish the wood you know?
[23:28:21] <pfred1> 110 years old I think it was due
[23:28:32] <andypugh> This is lovely, but I think the price is optimistic.
http://cgi.ebay.co.uk/Aciera-F4-Swiss-Milling-Machine-and-Tooling-Cabinet-/280507761086
[23:29:02] <pfred1> I'm sure it runs like a watch but yes that is steep
[23:29:27] <pfred1> I'm also sure German stuff is just as good if not better
[23:29:37] <andypugh> It does have all the toys (like a dividing head with spiral-feed gearbox)
[23:30:24] <pfred1> still its a mill if you want accurate thats what grinders are for anyways
[23:30:43] <andypugh> It's a pretty colour.
[23:31:24] <pfred1> guy selling it seems like a real gem to me from the description part of the ad
[23:31:32] <pfred1> timewaster disposing of
[23:32:08] <pfred1> kinda guy you leave their company and wish they'd get run over by a bus no doubt
[23:33:16] <pfred1> I went to school with this one kid who thought everything they had or did was so much better than everyone else it was sort of a standard joke
[23:33:44] <pfred1> "not as good as mine, but then again ..." was what we always said and everyone knew who that referred to
[23:34:39] <pfred1> that poor bastard is blind today so I guess he can't see how much better he is anymore?
[23:34:58] <andypugh> There is another example of that Mill on ebay with a 7k BiN, not nearly so nice and without the big cabinet of extras. Maybe the price isn't that unreasonable.
[23:35:28] <pfred1> it looks to be in great shape i shudder to think what it costs new
[23:35:55] <pfred1> but do you really need anything that nice? I mean are you going into the watchmaking business?
[23:36:02] <andypugh> It also looks like a nice non-destructive CNC candidate, especially that quill-feed.
[23:36:35] <andypugh> If I had £6000 I wouldn't have £6000 already, but I wouldn't be buying that.
[23:36:48] <pfred1> know what i noticed
[23:36:59] <pfred1> the t slots on the table just dump there's no wells
[23:37:26] <pfred1> so I guess it just lets the coolant pour wherever?
[23:37:54] <andypugh> The long, fixed, table has funnels at the end.
[23:37:55] <pfred1> I'm not so sure I'm 100% with that design feature
[23:38:18] <pfred1> but it just drains off the work table
[23:38:21] <andypugh> What's the point in wells with a tilting table?
[23:38:29] <pfred1> thing must look like Niagra falls when you're using it
[23:38:49] <pfred1> they'd catch something
[23:38:55] <andypugh> No, I meant that alternative table... It has a universal one and a fixed one as an option.
[23:39:09] <pfred1> oh you can change the whole table out?
[23:39:27] <Jean-Paul> Hello all is pncconf still available for testing
[23:39:28] <andypugh> http://www.lathes.co.uk/acieraf4/
[23:39:47] <andypugh> Full write up of that exact same machine. (some photos in fact)
[23:40:08] <JT-Hardinge> Jean-Paul: it is in 2.4
[23:40:44] <Jean-Paul> Thanks
[23:40:46] <pfred1> well its real nice but just strange enough that it makes me feel funny about it
[23:41:20] <andypugh> I really like it. I am coming round to the idea of mills with the Y on the ram. (The Huron ones do that).
[23:41:32] <JT-Hardinge> Jean-Paul: just open up a terminal window if you have 2.4 installed and type pncconf
[23:42:18] <pfred1> a lot of people just aren't comfortable with CLI and terminals
[23:42:35] <Jean-Paul> i have 2.3.someting
[23:42:46] <Jean-Paul> i will grab it now
[23:43:14] <JT-Hardinge> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?UpdatingTo2.4
[23:43:19] <pfred1> I hope EMC gets away from Ubunto though someday goes to a more stripped down distro
[23:43:50] <pfred1> probably better off to clean install
[23:45:28] <pfred1> andypugh to do some of the changeovers on this mill you'd better be strong
[23:45:56] <andypugh> Yeah, that table looks to have some heft to it, doesn't it?
[23:46:36] <pfred1> I was thinking about if you ever got the horizontal head for it
[23:46:50] <pfred1> but yeah the table is no lightweight I'm sure
[23:47:32] <andypugh> There is the horizontal had in the kit. Even if I had the £6000 and the desire to spend it, I doubt I could find for that accessory cabinet.
[23:48:13] <pfred1> it is one strange contraption remionds me of an overgrown sherline sort of
[23:49:15] <pfred1> half them accessories no one never changes
[23:49:24] <pfred1> I mean come on it'd probably take a week
[23:50:02] <pfred1> it works on the scale of something like a sherline but ah not so practical when you scale it up 5 times
[23:50:08] <andypugh> Look at the Aciera F1 on the lathes.co.uk site for a real kit-of-parts machine. (and tiny with it)
[23:52:45] <pfred1> now its cute
[23:53:12] <pfred1> it is quite the gizmo
[23:53:46] <pfred1> now i know what all the model makers buy as soon as they hit the big lottery
[23:56:20] <andypugh> Right, time to go.
