[02:59:15] <skunkworks> zeeshan: the base thread is pretty heavy lifting,.. (floating point and such) you may be able to increase it to 2-5khz - but not too much more.
[02:59:56] <zeeshan> so 200000 ns max
[03:00:18] <zeeshan> you mean decrease right?
[03:00:21] <skunkworks> you are not really going to gain much unless the machine is pretty high performance...
[03:00:41] <skunkworks> right - increase frequency - decrease period.. :)
[03:00:53] <zeeshan> you saw my servo error?
[03:00:54] <FinboySlick> zeeshan: It was a bit of a joke. Vim is very hard to use if you're not familiar with it.

[03:04:09] <zeeshan> btw i saw your thread on practicalmachinist
[03:04:11] <zeeshan> or was it cnczone
[03:04:17] <zeeshan> youve been working on that k & t for a long time!
[03:04:25] <zeeshan> that machine is a beast
[03:04:28] <skunkworks> we have had it since the mid 80's
[03:04:51] <Tom_itx> running linuxcnc since?
[03:08:27] <PetefromTn_> https://www.youtube.com/watch?v=VvdMJAs5NRM Ground control to Major tom..... sorta LOL. Can't decide which version I like better but I love that song....
[03:09:48] <PetefromTn_> skunkworks that Kearney and Trekker is a monster man. nice to know something you have had for that long is still working and making parts thanks to LinuxCNC!!
[03:11:03] <PetefromTn_> zeeshan Man that servo tuning is a beotch huh... it is so time consuming trying to tweak everything to be as good as you can get it.
[03:11:47] <zeeshan> yea haha
[03:12:23] <PetefromTn_> really glad to see you are getting almost ready to enjoy making parts on that machine tho.
[03:12:36] <zeeshan> so close! :)
[03:12:45] <zeeshan> i really am hoping to finish modbus tonight
[03:12:57] <PetefromTn_> you are the modbus guru LOL
[03:13:06] <zeeshan> im not gonna bother running shielded cable for my spindle encoder
[03:13:09] <zeeshan> too lazy
[03:13:13] <zeeshan> i already have wires toging there
[03:13:16] <zeeshan> but they are not shielded
[03:13:35] <PetefromTn_> my machine has differential encoder but it is running in shielded cabling because it was already there.
[03:13:38] <zeeshan> prolly just use deboeunce
[03:13:42] <zeeshan> *debounce
[03:13:53] <zeeshan> PetefromTn_: have you tried rigid tapping
[03:13:59] <PetefromTn_> yes many times LOL
[03:14:01] <zeeshan> nice man
[03:14:07] <Tom_itx> PetefromTn_ did you get yours converted to english speaking?

[03:15:00] <PetefromTn_> it is basically back to where it was before only with inch native measurements thanks to you guys Robh PCW Zeeshan etc etc.
[03:15:23] <PetefromTn_> I have not even turned it on today tho.
[03:15:35] <zeeshan> long live america
[03:15:38] <PetefromTn_> had a bunch of crap to take care of and pay some bills etc..
[03:15:39] <zeeshan> and the imperial system
[03:15:44] <PetefromTn_> hells yeah!
[03:15:46] <zeeshan> the machining class, they talk in metric units
[03:15:49] <zeeshan> i'm so lost in terms of feel
[03:15:58] <zeeshan> "yea can machine aluminum at 436km/h"
[03:16:26] <zeeshan> about 8000 m/s
[03:16:35] <toastydeath> it's aluminum so the answer is "Yeah you can machine it that fast"
[03:16:50] <zeeshan> yea but i dont have a feel for mm/s or m/s
[03:16:52] <PetefromTn_> I am just so used to working with machines setup for inch tool tables and most of the cutters I use are inch. Most of the parts I make are inch and even when they are not it is just metric dimensions in my cad cam so it is still all inch to me LOL
[03:16:54] <zeeshan> i bet PetefromTn does now
[03:17:22] <zeeshan> pete do you have a feel for
[03:17:30] <PetefromTn_> honestly I get plenty of metric work in the local shops
[03:17:31] <zeeshan> 121,111 mm/s
[03:17:37] <CaptHindsight> zeeshan: did you get your servos tuned?
[03:17:57] <PetefromTn_> was invited to work in ANOTHER shop in knoxville today heh
[03:18:11] <zeeshan> 286089 ipm
[03:18:12] <zeeshan> lol
[03:18:17] <zeeshan> CaptHindsight: i sold the machine
[03:18:25] * zeeshan jokes
[03:18:29] <PetefromTn_> gave up and said hell with it ;)
[03:18:30] <zeeshan> been working on modbus man
[03:30:29] <skunkworks> Tom_itx: linuxcnc sometime in the late 2009 or so iirc
[03:30:48] <pcw_home> I think the servos are fairly well tuned, the rest is stiction which is not really a tuning issue
[03:30:49] <skunkworks> ran the original control until then.. (until it smoked...)

[03:36:45] <zeeshan> i need to understand linear scales better. how do you calculate the number of encoder counts?
[03:37:04] <zeeshan> like the spec in the manual is 5 fold interpolation @ 25kHz
[03:37:12] <zeeshan> what does that exactly mean?
[03:37:43] <pcw_home> 25 KHz sine wave input
[03:37:43] -!- anth0ny_ has quit [Quit: anth0ny_]
[03:38:01] <zeeshan> what determines the fact that its 25kHz?
[03:38:02] <Valen> your encoder doesn't specify a resolution
[03:38:15] <Valen> ?
[03:38:15] <zeeshan> is it a predetermined thing based on the physical glass scale?
[03:38:18] <PetefromTn_> anyone got any good netfilx movie reccomendations? Got some drawing to do here and wanna watch something good LOL....
[03:38:18] <zeeshan> valen no
[03:38:29] <Valen> they don't say .001mm scales or something?
[03:38:30] <pcw_home> how fast the EXE can process the analog data
[03:39:08] <zeeshan> okay so thats telling the response rate
[03:39:18] <zeeshan> they dont mention any thing about resolution
[03:39:29] <zeeshan> another spec is "minimum edge seperation a"
[03:39:35] <zeeshan> .950us
[03:39:51] <Valen> if its connected to a computer the simple answer is move it a centimeter and see how many counts you get ;->
[03:39:57] <zeeshan> valen i did that
[03:40:01] <Valen> and?
[03:40:04] <zeeshan> but i want to understand it better rather than trial and error
[03:40:13] <zeeshan> i dont like knowing something :P
[03:40:24] <Valen> right the correct way to do it is to get the spec sheet from the manufacturer
[03:40:29] <Valen> which will specify the resolution
[03:40:32] <Tom_itx> zeeshan, wanna know a secret?
[03:40:47] <zeeshan> Tom_itx: let me guess you're going to say, i can't know it!
[03:40:51] <Tom_itx> heh
[03:41:12] <Valen> failing that, move it a known distance, then work out how many counts it is, then round it so its right
[03:41:25] <zeeshan> well thats how i got 25400
[03:41:26] <Valen> IE you move it 10mm and get 10001 counts, its going to be 100 counts per mm
[03:42:04] <zeeshan> i actually dont even know that..
[03:42:12] <zeeshan> why its 25400..
[03:42:18] <zeeshan> i was expecting a whole number
[03:42:18] <Valen> counts per what?
[03:44:09] <Valen> 25400 counts per?
[03:44:23] <zeeshan> i'm thinking :)
[03:44:27] <zeeshan> retracing what i did
[03:44:31] <pcw_home> inch probably (1 u)
[03:44:48] <zeeshan> moved it 10 thou
[03:44:58] <zeeshan> it overshot, then i found ratio
[03:47:37] <pcw_home> maybe a 20 micron pitch scale (so 5u resolution with quadrature) --> 5X EXE box --> 1 u
[03:47:46] <zeeshan> accuracy grade: +/- 5 um
[03:47:57] <zeeshan> signal period 20 um

[03:57:28] <PetefromTn_> LOL anything good I guess....sci fi? why ya got anything..
[03:57:57] <PetefromTn_> watching the whole nine yards right now....
[03:58:21] <FinboySlick> That's a cool one, especially since I was in Montreal when I watched it.
[03:58:31] <zeeshan> where the hell is this 1000 factor coming from
[03:59:01] <FinboySlick> PetefromTn_: You like dark comedy?
[03:59:11] <PetefromTn_> I guess so
[03:59:26] <FinboySlick> Ever watched 'Shallow Grave'?
[03:59:33] <PetefromTn_> nope
[03:59:41] <FinboySlick> One of Ewan McGreggor's first movies.
[04:00:11] <FinboySlick> Depends if you want a distraction or something you can focus on. I assume a distraction since you're drawing too.
[04:00:12] <PetefromTn_> aah Obi Wan...
[04:01:44] <FinboySlick> One of the better sci-fi I've watched recently was Automata.
[04:02:05] <PetefromTn_> is that the one with antonio banderas?
[04:02:10] <FinboySlick> Yes.
[04:02:15] <PetefromTn_> huh
[04:02:25] <FinboySlick> Too slow for your taste?
[04:02:41] <PetefromTn_> I saw that one on there but it looked kinda B grade from the cover is it good?
[04:02:59] <LeelooMinai> The table with electronic parts killed my suspension of disbelief - those capacitors and microswitches... come on:p
[04:03:08] <Valen> iron skies is awesome
[04:03:21] <PetefromTn_> on netflix?
[04:03:23] <FinboySlick> PetefromTn_: Yes, I quite liked it. It's not big budget but it doesn't need to be.
[04:03:24] <Valen> its B grade sci-fi, with space nazi's
[04:03:25] <LeelooMinai> But it had low budget.
[04:03:41] <Valen> but all the "science" is pretty right
[04:03:46] <Valen> and its funny as heck
[04:03:49] <FinboySlick> Valen: Have yet to watch that but it looked pretty nice.
[04:03:51] <PetefromTn_> cool..
[04:03:52] <LeelooMinai> I guess they had no money left after the CGI
[04:04:18] <PetefromTn_> I will check out those here after this one.
[04:06:00] <zeeshan> this doesnt make any sense to me. 1 count = 0.02mm , (1count/0.02mm)(25.4mm/1in)(1in) = 1270 counts
[04:06:09] <zeeshan> how am i getting 25400 on my encoder scale
[04:06:10] <FinboySlick> PetefromTn_: You seen District 9?
[04:06:12] <PetefromTn_> Hey this is looking up the chick from Species in on there LOL
[04:06:26] <zeeshan> there is a factor of 20 coming from somwhere?
[04:06:46] <PetefromTn_> yeah I saw that but it was kinda annoyingly graphic....sorta
[04:07:51] <PetefromTn_> I did not finish watching it tho..maybe it gets better in the end..
[04:08:03] <zeeshan> it must be the fact that its 10 fold interpolation.
[04:08:07] <zeeshan> 1270 * 10
[04:08:20] <zeeshan> and then there are two edges .
[04:08:30] <FinboySlick> PetefromTn_: It's probably the best, most awesome sci-fi I've seen in years. How far did you get?
[04:08:32] * zeeshan gives up , back to modbus
[04:08:50] <FinboySlick> PetefromTn_: you want big sound to fully appreciate it, mind you.

[04:10:26] <PetefromTn_> I dunno like I said it did not get finished at all.
[04:10:29] <FinboySlick> Well, the main character gets pretty sick mid-movie.
[04:10:47] <FinboySlick> But that's a leadup to pretty awesome stuff.
[04:11:16] <PetefromTn_> Honestly when I get movies I have young kids so if it gets real graphic I sometimes end up having to turn it off and try to watch it after they go to bed.
[04:11:51] <PetefromTn_> and USUALLY in the evenings I am out screwing around with my CNC schtuff so I wind up taking it back to redbox unwatched hehe
[04:12:07] <FinboySlick> Yeah, it's not kids friendly for sure. If you haven't spoiled it with trailers though, I highly recommend that you make it through.
[04:12:18] <PetefromTn_> OK willdo..
[04:12:30] <PetefromTn_> is it in netflix?
[04:12:43] <FinboySlick> Might be. I'm in Canada, we have cheapo-netflix.

[04:15:05] amnesic is now known as amnesic_away
[04:17:02] <PetefromTn_> Ya know what was a fantastic movie as far as acting.... the Lady in the water.
[04:17:23] <PetefromTn_> Paul Giamatti was amazing in that movie I thought
[04:17:35] <FinboySlick> A thing to notice about District 9 when you give it another go is that Vickus is just a regular schmoe trying to deal with the pretty crappy situation he's in. He's no hero and really just wants to save his skin. And then they turn the awesome dial to 11.

[04:22:28] <PetefromTn_> https://www.youtube.com/watch?v=KjhAKyiRL0k seriously one of the most powerful and moving scenes I think I have ever seen in a movie. Watching the scene alone does not really give you the full picture of what is happening.

[04:23:33] <FinboySlick> I hesitated bit because that guy just doesn't know how to *end* movies.
[04:23:58] <PetefromTn_> yeah
[04:24:47] <FinboySlick> I think he's stuck trying to outdo his 'The sixth sense' ending and failing miserably.
[04:25:02] <PetefromTn_> Oh he did that?
[04:25:06] <PetefromTn_> that was pretty good..
[04:25:10] <FinboySlick> Yeah, and *that* was quite good.
[04:25:16] <FinboySlick> But he also did Signs...
[04:25:24] <PetefromTn_> I liked signs..
[04:25:43] <PetefromTn_> he is good at that hiding the bad guy kind of thing right until the end.

[04:29:07] <FinboySlick> I tend to prefer little indie-ish movies lately.
[04:29:20] <FinboySlick> I had a lot of fun with 'Cheap Thrills'.
[04:29:51] <PetefromTn_> but I gotta say it left me balling my eyes out LOL.. You can FEEL the pain that man felt deep in his soul and it all comes out in that scene. I am probably sounding like a real goof here but oh well...

[04:30:44] <PetefromTn_> that would scare the crap out of me to run a press like that LOL
[04:30:54] <XXCoder> it requires special structure
[04:31:14] <PetefromTn_> I have had schtuff fly out of my little 20 ton press before just doing little stuff.
[04:31:31] <XXCoder> 35k for cnc drill
[04:32:12] <roycroft> there have been things that i have wanted to make very very flat before
[04:32:18] <roycroft> a 2500 ton press would be perfect for that

[04:36:49] <XXCoder> they has LOTS robot arms
[04:36:57] <LeelooMinai> They could at least give them some helmets...:)
[04:36:59] <FinboySlick> XXCoder: My sister is in Louisiana I think. Maybe she can squeeze it in her luggage.
[04:37:07] <XXCoder> heh
[04:37:15] <roycroft> helmets would do nothing
[04:37:28] <roycroft> they would be counterproductive, actually
[04:37:32] <PetefromTn_> yeah pretty much..
[04:37:37] <XXCoder> its Elio companym they bought a very big factory that used to make hummers and such
[04:37:37] <roycroft> they would give the workers a false sense of safety
[04:37:47] <PetefromTn_> anything that gets in there is done...simple as that.
[04:37:49] <XXCoder> roycroft: well would help for bumps and such
[04:38:02] <XXCoder> but yeah if machine screws up - blood puddles
[04:38:07] <LeelooMinai> Right, so maybe they should tell them to work naked, because clothes can give false sense of safety too:p
[04:38:20] <PetefromTn_> thats the night shift
[04:38:48] <roycroft> stuppin' in the stampin' room
[04:39:52] <PetefromTn_> that reminds me of a screwup I did years ago in woodworking
[04:40:15] <PetefromTn_> I was doing a complex installation with a more experienced pro woodworker
[04:40:30] <PetefromTn_> we had made this triple tier corner crown
[04:40:45] <PetefromTn_> and we were trying to fit it to the wall and ceiling
[04:41:05] <XXCoder> larger pic of 2500 ton press
http://www.eliomotors.com/wp-content/uploads/2015/01/Press1.jpg
[04:41:11] <PetefromTn_> I kinda screwed up the angle and it was JUST a touch off but I did not realize it until we had it glued up
[04:41:23] <PetefromTn_> so I was like well...
[04:41:43] <PetefromTn_> I will just take it over to the big 12" sliding miter box and just kiss the angle on the one side.
[04:41:53] <PetefromTn_> this piece was like over a foot tall
[04:42:09] <PetefromTn_> my parter was like no way man thats too dangerous
[04:42:21] <PetefromTn_> I said no I think I can do it..
[04:42:29] <SpeedEvil> Tablesaws are fun
[04:42:35] <PetefromTn_> so I plopped it up there on to miter box
[04:42:37] <SpeedEvil> very safe if you know how to use them
[04:42:48] <SpeedEvil> Murderous if you take the least little liability with them
[04:42:51] <PetefromTn_> setup the angle and tried to set the stop to the correct depth by eyeball
[04:43:01] <FinboySlick> PetefromTn_: The proper words for situations like that are: "Hold my beer and check this out."
[04:43:02] <PetefromTn_> He was standing there watching me...
[04:43:12] <PetefromTn_> I fired up the blade
[04:43:17] <XXCoder> lol
[04:43:20] <PetefromTn_> and SLOWLY brought it down into the part
[04:43:34] <PetefromTn_> it went real well right up until the last little tip
[04:43:36] <SpeedEvil> A sliding mitre saw?
[04:43:42] <PetefromTn_> then it grabbed!
[04:43:46] <PetefromTn_> and holy shit
[04:43:47] <SpeedEvil> It punched you in the chest
[04:43:53] <PetefromTn_> pieces were flying everywhere
[04:44:04] <PetefromTn_> I swear you would have thought a freakin bomb went off
[04:44:17] <PetefromTn_> there was painted pieces all around the saw
[04:44:25] <SpeedEvil> There is _so_much_ energy in that spinning blade that if stuff goes wrong, ...
[04:44:30] <PetefromTn_> luckily none of them hit me
[04:44:49] <PetefromTn_> I looked over at my partner and he was shaking his head laughing..
[04:44:56] <PetefromTn_> he said are you allright?
[04:45:00] <PetefromTn_> I said yeah..
[04:45:05] <PetefromTn_> he said I TOLD YOU SO!!
[04:45:17] <PetefromTn_> SpeedEvil there sure as hell is man.
[04:45:22] <PetefromTn_> LOTS of energy a
[04:45:42] <PetefromTn_> and it is difficult to put it into words just how powerful they are
[04:46:04] <PetefromTn_> I have LITERALLY made millions of precision cuts in woodworking my entire life
[04:46:07] <zeeshan> pete
[04:46:10] <zeeshan> i have good news :)
[04:46:21] <PetefromTn_> but it has bitten even me a couple times..
[04:46:29] <PetefromTn_> zeeshan yeah whats that?
[04:46:43] <FinboySlick> https://www.youtube.com/watch?v=u7sRrC2Jpp4
[04:48:15] <PetefromTn_> yup...
[04:48:21] <PetefromTn_> that has happened to me before too.
[04:48:45] <FinboySlick> PetefromTn_: The one with the tablesaw is pretty darn scary.
[04:48:50] <PetefromTn_> I always try to set blade height JUSt above the work and cut from the bottom but sometimes it is not possible
[04:49:13] <PetefromTn_> you think that is scary you should have been there to see that screwup I did with that miter box LOL..
[04:49:24] <PetefromTn_> the worst ever for me tho
[04:49:35] <PetefromTn_> I have about a four inch scar on my right wrist
[04:49:54] <PetefromTn_> the cut was from a piece of chemmetal laminate I was cutting on a sliding tablesaw
[04:50:03] <FinboySlick> Had large-ish drillpress grab one of my gloves once. Was weak in the knees for a little while after.
[04:50:04] <PetefromTn_> it kicked back and I deflected it with my arm
[04:50:23] <PetefromTn_> it sliced DEEP into my wrist and hit the bone.
[04:50:34] <PetefromTn_> luckily it did not hit anything real important
[04:51:00] <PetefromTn_> had I turned my wrist just a touch either way it would have been REALLY REALLY BAD.

[04:53:27] <PetefromTn_> http://i.imgur.com/llLTB4w.jpg this happened years ago..
[04:54:22] <XXCoder> heh I still got integation shaped scar on hand from nail getting though my hand and going out sideways
[04:54:29] <XXCoder> thankfully it didnt get between any bone
[04:55:20] <XXCoder> I was prying plank away from deck (we were demoing it) and I was p[ushing it upwards. stupid lol

[04:57:01] <XXCoder> but been decade since then
[04:57:41] <PetefromTn_> Well folks now that I got the inch or imperial dimensions native setup on the Cincinatti.
[04:58:01] <XXCoder> gonna run
[04:58:09] <PetefromTn_> I REALLY need to start thinking about the spindle orient
[04:58:25] <PetefromTn_> was chatting with my machininst friend today
[04:58:36] <PetefromTn_> and he was like...lemme get this straight.
[04:58:44] <PetefromTn_> you own a CNC vertical machining center
[04:58:52] <PetefromTn_> and it has a 21 tool changer
[04:58:59] <PetefromTn_> and you run it daily
[04:59:07] <PetefromTn_> but the toolchanger does not work????
[04:59:17] <PetefromTn_> I was like yeah I know I know LOL
[05:01:20] <PetefromTn_> trouble is I don't even know where to start.
[05:04:33] <zeeshan> sorry pete lol
[05:04:35] <zeeshan> got distracted
[05:04:37] <zeeshan> https://www.youtube.com/watch?v=YqR0IW2cKTY
[05:04:51] <zeeshan> it works it works it works!
[05:06:21] <FinboySlick> zeeshan: I wish I could interface with my vfd like that, but it's all in chinese and comes with no manual :P
[05:06:40] <zeeshan> FinboySlick: it has serial comms?
[05:06:54] <FinboySlick> zeeshan: I honestly don't know.
[05:07:10] <FinboySlick> It doesn't have a DB9 connector that I can tell though.
[05:07:53] <PetefromTn_> that looks pretty good man.
[05:08:04] <PetefromTn_> what signals can you monitor on it
[05:08:33] <PetefromTn_> does it have encoder feedback?
[05:08:38] <zeeshan> yea it has feedback
[05:08:43] <zeeshan> i dont think its necessary for our app
[05:08:54] <zeeshan> well at least for me. since i dont have tool changer
[05:09:00] <zeeshan> for you, its important :)

[05:10:00] <PetefromTn_> you like it then?
[05:10:18] <zeeshan> well its a hitachi drive
[05:10:24] <zeeshan> so im hoping its reliable
[05:10:26] -!- tronwizard has quit [Ping timeout: 246 seconds]
[05:10:28] <PetefromTn_> nice
[05:10:38] <zeeshan> i know its a 100% hitachi drive
[05:10:43] <PetefromTn_> I have had good luck so far with the two hitachi drives I have
[05:10:44] <zeeshan> cause every single parameter
[05:10:46] <zeeshan> is the exact sdame
[05:10:52] <zeeshan> from the programming menus
[05:10:57] <zeeshan> to the communication protocol
[05:11:11] <zeeshan> to the tech specs and dimensions
[05:11:20] <PetefromTn_> nice
[05:12:39] <zeeshan> did you find a 7.5HP single phase drive?
[05:12:42] <PetefromTn_> I found out today the original motor was a 3 speed motor..
[05:13:10] <PetefromTn_> not really sure how that affects the choice of the new motor
[05:13:56] <zeeshan> not a big deal with a vfd
[05:13:58] <PetefromTn_> not picked a drive yet because have not determined the motor choice yet.
[05:14:10] <PetefromTn_> I would not think so but I dunno really
[05:14:30] <zeeshan> 3 speed motor is a good thing because its been designed to operate for long periods of time at 3 diff speeds
[05:14:38] <PetefromTn_> my most important criteria is getting the max torque out of the system
[05:14:39] <zeeshan> so you can definitely vary the range on the speed
[05:14:41] <zeeshan> without burning up motor
[05:15:43] -!- FinboySlick has quit [Quit: Leaving.]
[05:17:30] <PetefromTn_> yeah
[05:18:02] <PetefromTn_> I am thinking a low RPM motor like 1200 or 1700 with the right setup of pullies will get me what I want coupled with the VFD
[05:21:33] <zeeshan> yea]
[05:25:23] <PetefromTn_> zeeshan Got any ideas how I could get spindle orient working with the hitachi since it is apparently similar to your vfd?
[05:28:06] <zeeshan> PetefromTn_: these vfds want eeither a sensor that outputs current or voltage
[05:28:25] <zeeshan> so basically since you already likely have a spindle encoder going to 7i77
[05:28:43] <PetefromTn_> I do
[05:28:51] <zeeshan> maybe you can output -10 to +10v signal analog
[05:28:53] <zeeshan> to your vfd
[05:29:17] <zeeshan> you will need to calibrate your analog output to make your motor speed
[05:29:46] <zeeshan> so basically you'll be monitoring velocity
[05:29:54] <zeeshan> and do a velocity feedback loop @ the vfd.
[05:30:10] <zeeshan> make = match
[05:31:22] <zeeshan> now that i think about it
[05:31:37] <zeeshan> you probably dont even need a pid loop on the vfd..
[05:31:46] -!- erictheise has quit [Quit: erictheise]
[05:32:01] <zeeshan> you can probably do a velocity feedback loop in linuxcnc?
[05:32:11] <PetefromTn_> that would be nice
[05:32:19] <zeeshan> you already have an encoder giving it information about your spindle rpm
[05:32:22] <PetefromTn_> I would think since I have feeback already
[05:32:25] <zeeshan> and youre outputting 0-10v
[05:32:50] <PetefromTn_> valen watching iron sky man!!
[05:34:08] <PetefromTn_> perhaps all we need is some sort of seperate macro that will use the existing signals
[05:35:51] <PetefromTn_> or rather all I need LOL
[05:38:37] <PetefromTn_> hey they have VW beetles on the dark side of the moon LOL
[05:39:20] <SpeedEvil> Of course they don't.
[05:39:29] <SpeedEvil> VW beetles are aircooled - they'd overheat immediately

[13:07:53] <Tom_itx> i see no metal shavings...
[13:08:25] <zeeshan> hehe
[13:08:30] <zeeshan> still a while from there
[13:08:32] <zeeshan> need tool :/
[13:08:48] <zeeshan> prolly get them by next week
[13:08:49] <Tom_itx> is that what your modbus looks like?
[13:09:02] <zeeshan> yes
[13:09:14] <zeeshan> this one spindle vfd was a pain cause it did not use modbus
[13:09:21] <zeeshan> it used its own serial protocol
[13:09:42] <zeeshan> most time consuming part was trying to modify a modbus library to add an extension to it
[13:09:58] <jdh> it isn't a 'pain', it is an opportunity to succeed.
[13:10:21] <zeeshan> its a pain man, regular modbus vfd takes like at most 1hr to write the driver for
[13:10:28] <zeeshan> maybe 4hours
[13:10:32] <zeeshan> this thing took 4 days
[13:11:18] <jdh> how long would it take now.
[13:11:26] <zeeshan> about the same
[13:11:27] <zeeshan> :P
[13:11:54] <Tom_itx> did you save a copy of it?

[15:40:21] <jdh> oops
[15:45:54] <Jymmm> What you do jdh, WHAT DID YOU DO!!!
[15:46:53] <jdh> not me, he cursed his computer by not saving important work elsewhere.
[15:49:24] <malcom2073> There's a computer joke about "Jesus Saves", but I forget it
[15:49:47] <jdh> save early, save often.
[15:49:55] <archivist> what, you did not back it up?
[15:50:00] <malcom2073> I like that solidworks pops up a window when I haven't saved recently
[15:51:27] <jdh> that's annoying.
[15:51:33] <jdh> auto-save to a recovery file in teh background
[15:51:47] <jdh> I really despise anything that pops up and steals focus
[15:52:22] <malcom2073> It doesn't steal focus
[15:52:28] <malcom2073> just a little window inthe bottom right
[15:52:53] <malcom2073> Not a popup really, part of the main screen, but it "looks" like a window
[15:53:11] <malcom2073> but yeah auto-saving to a recovery file would be cool
[15:56:36] <pcw_home> real operating systems have file versions :-)
[15:56:37] amnesic_away is now known as amnesic
[15:58:30] <unfy> as far as focus, my primary hate.... that i still foam at the mouth over to this day.... is the old X11 "sloppy mouse focus" stuff
[15:59:10] <unfy> where the WM moves focus to whatever is beneath the mouse cursor, even without a click. as someone who "tosses his mouse" to the side / corner of screen constantly - that drove me batty
[15:59:26] <malcom2073> I like not having to click on a window to scroll things :/
[15:59:51] <unfy> and - ITS BEING USED TODAY still! folks are doing it in web things! you put your mouse over a search thing, you click on it and get a box. move the mouse away and BAM - it hides the search thing
[16:00:40] <unfy> annnnnnyway. /rant :D
[16:01:59] <archivist> not as bad as the win8 hiding the vertical scroll bar from the screen
[16:02:41] <unfy> "does it need to be there all the time" ... "should it be context aware" ... i dunno.
[16:02:55] <unfy> on a small screen i actually use the auto hide task bar stuff....
[16:03:12] <unfy> sadly, none of the context aware shit ever works correctly ._.
[16:03:20] <archivist> you have to wave right get the bar back to get further down a page
[16:04:37] <unfy> there is much about win8 that attempts to bring the tablet / phone experience to the PC ... which... outside of a tablet pc... makes no sense ._.
[16:04:51] <unfy> i still haven't used win8 for more than an hour overall
[16:05:03] <mozmck> same for gnome3 and unity
[16:05:11] <unfy> ugh ._.
[16:05:13] <_methods> that's why i use xfce
[16:05:15] <_methods> it's all i need
[16:05:16] <_methods> simple
[16:05:19] <_methods> lightweight
[16:05:19] <unfy> xfce <3 window maker <3
[16:05:26] <unfy> (or afterstep heh)
[16:05:42] <Rab> unfy, focus-follows-mouse is the first thing I turn on. I still think it's the best thing since sliced bread. ;)
[16:05:48] <unfy> i wrote several of my own dock apps for as/wm :D
[16:05:59] * unfy chews on rab's corner! nu nu nu nuuuuuuuuu
[16:06:00] <mozmck> and the gnome3 folks attitude is as bad as or maybe worse than microsoft's
[16:07:30] <mozmck> I use xfce, but I use the Nemo file manager (fork of nautilus with all the good features left in etc.)
[16:08:47] <Rab> http://www.all-day-breakfast.com/wmx/
[16:08:51] <Rab> ^^ best WM of all time

[16:11:02] <_methods> hmmm i might try that i just use thunar
[16:11:44] <mozmck> thunar is pretty nice, but I like having tabs in the file manager, so I don't have to open so many windows.
[16:12:19] <unfy> wmx looks a bit beos like....
[16:12:25] <unfy> and.... i think i like it <3
[16:12:46] <unfy> i miss the old days when i had time to mess around with such things
[16:13:08] <mozmck> I also use nemo-terminal which embeds a small terminal at the top of the directory window. Very nice for running a quick command in a directory such as "git pull" :)
[16:13:57] <mozmck> There are also hotkeys to switch between bookmarks and tree view on the left which I don't think Thunar has.
[16:15:08] <mozmck> I also use rabbitvcs which integrates nicely with nemo and shows me at a glance if one of my 40+ projects has changes which are not commited.

[16:33:09] <mozmck> jthornton_: I wonder if you can have 10.04 write out an xorg.conf that works, then use it in one of the others?
[16:33:39] <jthornton_> everytime I add an xorg.conf file the computer will not boot up
[16:34:01] <mozmck> that's odd.
[16:34:28] <jthornton_> there is no xorg.conf file of any kind on this machine
[16:34:55] <pcw_home> Yes but only when order is entered (We have been doing inventory, but will be done today so the order should be entered/shipped today or tomorrow)
[16:35:32] <jthornton_> mozmck, with 10.04 lspci -k gives me 00:0d.0 VGA compatible controller: nVidia Corporation C61 [GeForce 6150SE nForce 430] (rev a2)

[17:30:00] <jdh> it hasn't had any gcode it in for a couple years. just plastic printing shit
[17:30:13] <toastydeath> compared to the conversational languages of toy controls
[17:30:18] <toastydeath> it just spanks everything
[17:30:24] <norias> hmm, new fanuc?
[17:30:34] <PetefromTn_> but those prototrak ads always feature some old guy that is in business and implies he never needs to learn G code LOL...
[17:30:36] <norias> how about, implement the standard?
[17:30:56] <toastydeath> nobody implments the standard, so why start now
[17:31:02] <toastydeath> plus the shit they're adding is incredible
[17:31:11] <norias> lol
[17:31:13] <norias> fair
[17:31:16] <PetefromTn_> what shit who is addins?
[17:31:19] <PetefromTn_> adding?
[17:31:28] <toastydeath> Fanuc basically implemented conversational g-code
[17:31:32] <norias> yeah, what are they adding?
[17:31:55] <toastydeath> up in the g300 range, there's g-code canned cycles for all kinds of stuff similar to lathe canned cycles for roughing and finishing
[17:32:05] <toastydeath> like facing, pocketing, contouring
[17:32:13] <norias> yeah
[17:32:15] <toastydeath> they also added some virtual path controls
[17:32:22] <PetefromTn_> in conversational?
[17:32:25] <norias> oh
[17:32:26] <toastydeath> no, it's all in g-code
[17:32:28] <norias> eh.
[17:32:34] <norias> i've been doing that forever
[17:32:36] <toastydeath> but the control itself has live documentation
[17:32:36] <PetefromTn_> well yeah
[17:32:43] <norias> just write a generic sub
[17:32:47] <norias> for like pockets
[17:32:49] <PetefromTn_> most manufacturers have their own particular bent on G code...
[17:33:04] <PetefromTn_> many are quite interesting and useful.
[17:33:05] <toastydeath> of course they do, and i'm saying i've used a shitload of controls
[17:33:11] <toastydeath> and the new fanuc shit is amazing
[17:33:19] <norias> at the end of the day, if g-code is implemented well
[17:33:22] <toastydeath> by comparison to the piddly options other manufacturers have
[17:33:25] <norias> i.e. has loops, logic control
[17:33:37] <norias> calling of subs that can pass args
[17:33:44] <norias> the sky's the limit
[17:33:45] <PetefromTn_> I just get amused by those prototrak ads...
[17:34:08] <toastydeath> everyone can do that, and that's not impressive
[17:34:11] <norias> i get very unexcited by additional g-code commands
[17:34:15] <norias> that aren't portable
[17:34:24] <PetefromTn_> the idea that anyone who is smart enough to be a machinist would have issues with learning something that is not conversational..
[17:34:34] <PetefromTn_> cracks me up..
[17:34:51] <norias> i've met some dumb machinists
[17:34:58] <toastydeath> I think that's coming mostly out of the printing movement where people want parts but don't want to have to learn anything
[17:35:10] <PetefromTn_> my brother in law has a prototrak equipped CNC knee mill. When I was out there in Norcal visiting he showed it to me...it was not too impressive really.
[17:36:53] <PetefromTn_> well gotta go meet my wife for lunch.. BBL

[18:31:36] <toastydeath> one pcie 2.0 lane is just barely slower than SATA

[18:36:17] <toastydeath> I don't know how they present themselves to the bios, i'm not familiar with the pcie handshake/probing
[18:36:23] <pcw_home> I would expect so
[18:36:52] <norias> does the motherboard have to have special support for the PCIe HD?
[18:36:59] <norias> or is it largely plug and play
[18:37:09] <pcw_home> PNP
[18:37:13] <norias> no kidding
[18:37:31] <norias> i think
[18:37:37] <norias> i'm going to document this build really well

[18:41:01] <mozmck> anyone have experience with this MB? Pretty good price right now:
http://www.newegg.com/Product/Product.aspx?Item=N82E16813135391
[18:41:14] <norias> linuxcnc preinstalled and pre-configured for the hardware
[18:41:54] <CaptHindsight> norias: too many variations, plus most people handy enough to use Linuxcnc are handy enough to build their own
[18:43:18] <CaptHindsight> plus lots of users are on tight budgets, if there was a $499 linuxcnc box with $475 in parts you'd hear about the $24 markup
[18:43:42] <norias> ha!
[18:43:52] <SpeedEvil> http://www.mauve.plus.com/opensourcehw.txt
[18:43:58] <norias> same could be said about linux generally
[18:44:00] <SpeedEvil> this is some of the issues in making modern computer hardware
[18:44:11] <norias> why doesn't everyone just compile their own kernel?
[18:44:18] <SpeedEvil> this was wrtitten about mobile phone class hardware.
[18:44:23] <SpeedEvil> But the same pretty much applies.
[18:44:31] <norias> right on
[18:44:45] <SpeedEvil> The basic problem is a 'compile' of a linuxcnc capable motherboard may be the thick end of a thousand dollars.
[18:45:15] <norias> i think the value is in "tested and known to work"
[18:45:46] <SpeedEvil> The problem with tested and known to work hardware is that the manufacturer is normally under no obligation not to change it.
[18:45:52] <norias> i.e. don't spend a bunch of time on irc and forums finding the right hardware
[18:46:00] <norias> no, and that's fair, too
[18:46:06] <pcw_home> and your thousands of dollars and months of time have gone into something thats obsolete
[18:46:25] <norias> where do the thousands of dollars come from?
[18:46:31] <norias> i see boards for... $60
[18:46:34] <SpeedEvil> Now, there are vendors out there that guarantee to sell parts for extended periods.
[18:46:36] <SpeedEvil> They are not cheap
[18:46:42] <norias> i think this machine, altogether, will cost $500
[18:46:56] <pcw_home> (that was about building from scratch)
[18:47:01] <norias> oh, heck with that
[18:47:06] <SpeedEvil> norias: In order to sell a motherboard for $60, you need to build 50K of them
[18:47:23] <norias> i'm saying start with something relatively simple
[18:47:26] <norias> one class of stuff
[18:47:33] <pcw_home> the J1800/J1900 MBs are decent, low power and cheap
[18:47:34] <norias> oh, i'm not saying make the boards
[18:47:44] <roycroft> you find a cheap system board that works with linuxcnc
[18:47:47] <roycroft> for <$100
[18:47:47] <norias> i'm saying buy stuff off newegg
[18:47:52] <roycroft> then you buy two of them
[18:47:54] <norias> put it together in a box
[18:47:57] <roycroft> leave the other one in a box
[18:48:02] <norias> test it out well
[18:48:05] <roycroft> when the first one dies, you install the second one
[18:48:07] <CaptHindsight> laptops and some servers have 100% margins or more where desktop parts are in the few % range
[18:48:10] <norias> and offer it as the "no research" options
[18:48:11] <roycroft> and start looking for another board that works
[18:48:29] <SpeedEvil> norias: and you're selling that, and then the manufacturer changes the BIOS
[18:48:37] <SpeedEvil> norias: and it goes from 10us latency to 5ms
[18:48:47] <norias> i know tons of people in to cnc as hobby
[18:48:52] <norias> that don't want to learn all that stuff
[18:49:06] <roycroft> the other option is to find a machine that works and that the federal government buys
[18:49:07] <pcw_home> If you are not after really low latency for software stepping, almost anything can be made to work
[18:49:11] <norias> or, machine shops with dead machines
[18:49:22] <roycroft> the government requires parts availability for five years
[18:49:28] <roycroft> as part of its contract
[18:49:31] <norias> right
[18:49:41] <norias> i think it's doable
[18:49:43] <roycroft> so you if you use a governement model you can be sure to get it fixed for five years
[18:49:50] <norias> i don't think you'd make tons of money
[18:50:19] <norias> but if you had, say, two tested mobo's
[18:50:19] <roycroft> but almost any computer will work for linuxcnc with a mesa board, won't it?
[18:50:35] <SpeedEvil> norias: It's all doable.
[18:50:40] <norias> if supplier A changes
[18:50:41] <roycroft> you're offloading the real time stuff to the mesa board
[18:50:43] <norias> switch to B
[18:50:44] <SpeedEvil> norias: the problem is - is it doable at a profit.
[18:50:52] <norias> oh, really?
[18:51:02] <pcw_home> My experience is that almost any newer Intel MB will work
[18:51:06] <norias> i think it is if you don't dive in to it deep
[18:51:14] <SpeedEvil> norias: if you're using an off-the-shelf board, what's to stop people just seeing 'oh - they've used board X' - I will buy that board - and not paying you
[18:51:15] <norias> if it's just a side thing
[18:51:19] <pcw_home> and many AMDs will also
[18:51:27] <SpeedEvil> And that too.
[18:51:27] <norias> sure, some people would do that
[18:51:43] <SpeedEvil> 'guaranteed' - when most motherboards work to a reasonable degree is a questionable thing
[18:51:57] <SpeedEvil> The sane thing is probably to make a nice USB controller.
[18:51:58] <pcw_home> I think you are worrying too much about PC choice
[18:52:02] * roycroft dosn't see a significant market for linuxcnc-specific machines
[18:52:05] <norias> maybe i am
[18:52:23] <SpeedEvil> Which can run most of the hard-realtime algorithms on that, and has full linuxcnc support
[18:52:29] <norias> i think after i build this machine
[18:52:36] <roycroft> i agree about worrying too much about the peecee
[18:52:42] <norias> i'll just make a second controller box
[18:52:46] <norias> stick it on my website
[18:52:50] <norias> and see if someone bites
[18:53:20] <norias> i'd have about $500 in, and if it doesn't sell
[18:53:21] <norias> eh
[18:53:32] <norias> sell the mesa cards to someone
[18:53:36] <norias> and i've got a little computer
[18:53:40] <norias> pretty low risk
[18:54:17] <pcw_home> J1800/1900/2900s work fine

[19:11:51] <pcw_home> so if you have a sensor connected to an encoder input (and the encoder input is jumpered for TTL mode)
[19:11:52] <pcw_home> the sensor has to pull down (NPN output)
[19:11:54] <pcw_home> On the other hand if these are really slow sensors for a low res encoder, you may be better off using field I/O inputs
[19:11:55] <pcw_home> read at the servo thread rate
[19:12:50] <zeeshan> these are spindle encoder

[19:14:33] <zeeshan> sdsalkdjsa 100.
[19:14:51] <zeeshan> must be doing math wrong somewhere
[19:15:17] <Tom_itx> x4 for quadrature
[19:15:18] <pcw_home> Yeah you can do that but the encoder input needs a pulldown for a PNP sensor
[19:15:39] <pcw_home> 400 counts/rev
[19:16:30] <zeeshan> can i hook up to mpg input?
[19:16:43] <pcw_home> no index
[19:17:07] <pcw_home> if you have the PNP sensors just use a pulldown

[19:21:04] <Tom_itx> 22k ... i had made a note of it
[19:21:19] <Tom_itx> just double checking
[19:21:53] <pcw_home> and input threshold is ~50% of Vfield
[19:22:18] <pcw_home> (60% going high, 40% going low)
[19:23:02] <pcw_home> so at 24V thats 14.4V high and 9.6V low

[19:45:59] <zeeshan> can these sensors be wired for differential?

[20:04:20] <zeeshan> i think i finally understand this pull up / pull down stuff
[20:04:51] <zeeshan> so currently on the encoder inputs there are pull up resistors between vcc (5v) and the pin.
[20:06:16] <zeeshan> 2K ohms if jumpered in TTL , so i ned to provide a path to ground now to make it at logic state low
[20:06:24] <zeeshan> if i directly connected a wire to ground, it would be a short circuit
[20:07:00] <zeeshan> i dont get why it needs to be a 22k ohm resistor though
[20:09:16] <PetefromTn_> hehe it's magic man...just go with it.
[20:09:20] <zeeshan> haha
[20:11:28] <zeeshan> just to triple confirm........... i would use encoder 5's ground terminal on the 7i77
[20:12:04] <zeeshan> for one leg of the resistor, the other leg would go to qb5, another at qa5, another at idx5

[20:27:01] <PetefromTn_> why would I be choosing a motor if it had a motor?
[20:27:30] <PetefromTn_> the machine came to me without a spindle motor, Z axis motor, or Z ballscrew.
[20:28:45] <PetefromTn_> I got information from the manufacturer about the original motor and it apparently came with a three speed 3ph motor and the part number does not even come up in a google search.

[20:29:02] <zeeshan> lol PetefromTn_
[20:29:19] <PetefromTn_> it is a C frame or face mount motor but the motor mount plate does not seem to match any of the standard frame sizes..
[20:29:27] <PetefromTn_> at least not any that I come across...
[20:29:38] <zeeshan> do you have a drawing of the flange for your machine
[20:29:51] <jdh> fortunately, you have a VMC and can make an adapter plate.
[20:29:56] <zeeshan> yea
[20:29:59] <PetefromTn_> I posted the information here before..
[20:30:03] <zeeshan> thats what i had to do on my old manual bridgeport clone
[20:30:14] <zeeshan> and used a standard c frame motor
[20:30:16] <PetefromTn_> yeah I can make anything but I would like to find something that is made to fit
[20:30:23] <zeeshan> why
[20:30:34] <zeeshan> usually that is the expensive route :P
[20:30:37] <PetefromTn_> so I don't have to screw with stuff just bolt the damn thing in..
[20:30:48] <PetefromTn_> yeah probably...
[20:30:59] <PetefromTn_> honestly I am not averse to making mods to the plate
[20:31:02] <zeeshan> electric motors are so stupid expensive new
[20:31:03] <jdh> and, you like making things
[20:31:16] <PetefromTn_> but the plate has a large hole with four bolt holes outside of it...

[21:02:30] <zeeshan> PetefromTn_: think the bolt circle is 9"?
[21:02:54] <zeeshan> looks very much like a 284T frame motor
[21:05:11] <PetefromTn_> large hole is about 7 1/8" and bolt circle is about 8.5"
[21:06:10] <PetefromTn_> 284 T does not even appear to be a face mount frame?
[21:06:12] <zeeshan> http://www.hydramount.com/products/cmotor.php
[21:06:14] <zeeshan> have you seen that?
[21:06:44] <zeeshan> tc i meant
[21:08:02] <PetefromTn_> in that graph the AJ dimension would need to be the 8.5" and the AK or register would need to be the 7 1/8"...
[21:08:47] <PetefromTn_> I assume the bolt pattter diameter is measured from the center of the bolt holes not the outer edge right?
[21:08:56] -!- toastydeath has quit [Read error: Connection reset by peer]
[21:08:56] <zeeshan> yea center to center
[21:09:58] <PetefromTn_> yeah that is what I figured..
[21:10:24] <PetefromTn_> so like I said the main hole is 7.125 and the bolt circle diameter is 8.5"
[21:10:34] <PetefromTn_> which does not seem to fit any of those frame styles
[21:10:56] <PetefromTn_> and even if I wanted to make it fit I would be looking at making an entirely new plate basically..
[21:12:19] <PetefromTn_> Dunno what frankenstein motor they put in this thing but it does not seem to be anything normal heh
[21:12:29] <zeeshan> show pin
[21:12:32] <zeeshan> er
[21:14:29] <PetefromTn_> notice from the diagram picture that the register ring is outside of the bolt hole pattern whereas my plate is the opposite.

[21:19:35] <zeeshan> custom adapter plate time! :P
[21:19:54] <zeeshan> the benefit of that would be if you ever had to replace it too
[21:19:59] <zeeshan> you can buy a standard motor
[21:20:09] <zeeshan> bridgeport clone is the exact same way :/ weird motor type
[21:21:00] <PetefromTn_> honestly I have found a couple local motors that are the right speed and HP for good prices but none are face mount they are all foot mount. I would need to fabricate a custom mount and try to ensure it is horizontal perfectly....would rather not screw with that if possible.

[21:53:01] <Tom_itx> you must update from 2.5x to 2.6 first though
[21:53:20] <PetefromTn_> MPM1901FRM381 that is the part number I got from Standard Modern. I honestly would love to find some information about it but so far nothing.

[21:55:56] <zeeshan> man that is BAD ASs
[21:56:00] <PCW> 190 is 190 MM
[21:56:04] <zeeshan> i love spindles with servo motors
[21:56:15] <Tom_itx> heh
[21:56:20] <PetefromTn_> it was apparently sold along with the anilam control and equipped with Custom Servo Motors parts
[21:56:29] <zeeshan> that is very cool dude
[21:56:39] <zeeshan> you have crazy indexing abilities :P
[21:56:47] <zeeshan> without the induction motor slip bs
[21:56:48] <PetefromTn_> it would be if the motor was still in there heh
[21:57:02] <PCW> pretty sure Custom Servo Motors was bought out by Parker
[21:57:03] <zeeshan> its prolly gone cause its 1000bux
[21:57:04] <zeeshan> :P
[21:57:26] <PetefromTn_> why would they put an encoder on the spindle if they used a servo for a spindle motor?
[21:57:41] <zeeshan> prolly external edcnoder
[21:57:55] <PetefromTn_> the spindle has a really nice timing belt driven encoder
[21:58:07] <PetefromTn_> on a servo motor?
[21:58:39] <zeeshan> im talking out of my butt :)
[21:59:56] <PetefromTn_> I dunno I am sure the thing COULD have had a servomotor for the spindle but I seriously doubt that is what I will be putting back into the machine. If that is the case it would explain the non standard motor mount plate but not the spindle mounted encoder
[22:00:25] <PCW> It may have been induction motor (but check the mounting Ill bet thats the frame)
[22:00:28] <PetefromTn_> I will be lucky if I can afford to put back a quality 7.5hp low RPM AC 3phase motor and drive
[22:01:02] <PetefromTn_> I have no information on the original motor frame size other than it MAY have been made by parker as you suggest.

[22:18:34] <Tom_L> you'd think there would be an easy way...
[22:19:07] <PCW> probably the original would be a bit more HP than you can comfortably run
[22:19:22] <PetefromTn_> apparently 7.5 HP
[22:19:29] <PetefromTn_> according to the nameplate
[22:19:43] <PetefromTn_> what makes you say that?
[22:19:54] <malcom2073> Heh, price to pixel ratio on that auction is funky
[22:21:00] <PetefromTn_> http://www.ebay.com/itm/CONTROL-TECHNIQUES-190EZB301CAAAA-AC-SERVO-MOTOR-3000-RPM-NEW-/321577096905?pt=LH_DefaultDomain_0&hash=item4adf7d16c9
[22:21:07] <PCW> just because most of the servo motors in that size are 12 or more HP
[22:21:09] <PetefromTn_> another high priced option
[22:21:35] <Tom_L> that one looks wicked
[22:21:51] <PetefromTn_> I am hoping that the narrow square frame type of the original motor will not preclude my inserting a typical 3 phase face frame mount motor in there...
[22:21:57] <PCW> probably about 20 HP
[22:22:50] <Tom_L> stall 43.2 Nm
[22:23:04] <PetefromTn_> I suppose If that happens I will be forced to make a custom mount that holds the motor 180 degrees the other way
[22:23:08] <PCW> If it was a induction motor, it would have a lower rating so it probably was an induction motor in the frame
[22:24:12] <PetefromTn_> that part number I posted is the one I got from the Manufacturer.. I will be hearing hopefully from Parker here soon and I will know the particulars of the motor.. all I know is it was 7.5HP
[22:25:25] <PetefromTn_> it would be my luck to buy a lathe that had an uber expensive servomotor in it that has been removed. going back with one is basically out of the question as far as price is concerned.
[22:26:50] <PCW> it likely was a induction motor, just wounds on a a rectangular 190 mm frame
[22:26:55] <PetefromTn_> I am going to take some quick measurements of the motor housing area to see what I am up against here. Looks like I will absolutely have to modify that mounting plate which is not really a big deal but I was hoping to be able to just buy a nice AC motor and vector drive and be done with it.

[22:29:10] <PetefromTn_> shit...
[22:29:28] <PetefromTn_> the rectangular opening where the motor goes in is only about 9" wide...
[22:29:53] <PetefromTn_> almost ANY 3 phase induction motor I buy will be wider than that I am sure..
[22:30:04] <Tom_itx> need a bit of room around it for cooling too
[22:30:42] <PetefromTn_> well actually there is a LOT of room inside there but the openining you have to stick it thru is only 9" wide
[22:31:21] <SpeedEvil> Grease the edges of the hole.
[22:31:48] <PetefromTn_> fortunately there is an enclosure on the headstock side of the machine that houses the spindle encoder and some other things that is more than long enough to mount the motor opposite to it's typical mounting

[22:38:53] <PetefromTn_> you can see the large enclosure outside of the rectangular hole where the motor goes.
[22:39:21] <zeeshan> HEHEhe something intriguing about watching the serial port for communication
[22:39:27] <PetefromTn_> you can also see that there are sliders to allow you to easily insert the motor and then load the belts and adjust it to tension without it falling thru
[22:39:32] <zeeshan> buncha 0s and 1s :)
[22:41:21] <PetefromTn_> you can see the lower rectangular hole has four bolt holes around the edge that is where the mount plate goes.
[22:42:54] <PetefromTn_> perhaps I should just take that plate and make a weldment on it horizontally that places the motor outside of the hole and locates the motors shaft in the same plane it would be if it were inside the hole.
