[00:01:31] <andypugh> Things to try: 1) Put a stud from a good holder into the naughty holder, see if things are better. Perhaps it’s a longer stud?
[00:02:27] <andypugh> 2) See if the new holder is longer from flange to stud-seating face (not definitive, there may be different gaps between the taper gauge line and the flange)
[00:02:48] <PetefromTn_> he needs to push a holder in there without a pullstud and see how far it goes up and take a photo for comparison
[00:03:16] <zeeshan> pete
[00:03:19] <zeeshan> okay good idea
[00:03:22] <zeeshan> heres some pics.

[00:03:31] <zeeshan> its not making contact properly i guess
[00:03:34] <zeeshan> you can see the lines.
[00:03:40] <zeeshan> in the bluing where it has made contact

[00:03:52] <andypugh> PetefromTn_: I thought about that, but removing the pullstud… No, wait, I didn’t think of that. I thought of removing the drawbar (big job) not the pullstud (trivial job). Doh!
[00:03:56] <zeeshan> thats the stud to holder.
[00:04:09] <zeeshan> lemme take pic of just holder by itself

[00:06:30] <anonimasu> you can screw the pullstud out i think
[00:06:33] <anonimasu> with a special tool
[00:09:38] <andypugh> HSK has both face and taper contact, partly through using a thin-walled taper.

[00:10:40] <andypugh> The Tormach TTS achieves the same thing in a different, and cheaper way. But that basiclly relies on frction and (apparently) tends to loose the axial clamp. It is still fairly clever though.

[00:13:21] <zeeshan> without a pull stud
[00:13:42] <zeeshan> i measured the difference with feeler gauges, and there is a 3 thou diff between the two.
[00:13:50] <zeeshan> w/ the pull stud in the tool holder
[00:13:54] <furrywolf> apparantly I need to learn german. yay.
[00:13:59] <zeeshan> the tool sticks out 3 thou more .
[00:14:08] <zeeshan> so clearly something is up!
[00:14:08] <andypugh> That’s not going to matter
[00:14:26] <zeeshan> why andypugh
[00:14:29] <andypugh> Now compare flange to pul-stud distance
[00:14:35] <furrywolf> someone I know bought a unimog... and everything is in german. all the labels on all the switches that don't work (which is all of them except the headlights) are german, as is the manual to fix them...
[00:14:49] -!- patrickarlt has quit [Remote host closed the connection]
[00:15:00] <zeeshan> andypugh: no way to measure that at home
[00:15:00] <zeeshan> lol
[00:15:05] <zeeshan> precisely that is.
[00:15:15] <andypugh> Well, OK, 3 thou might matter for clamping, but you would expect more than 3 thou of residual travel in the drawbar.
[00:15:16] <zeeshan> actually nm
[00:15:32] <zeeshan> i can measure with a height gauge on a granite plate
[00:15:43] <furrywolf> I assume having a fourth locked position between 1-2 and 3-6 on the tranny is normal? it feels like it's designed that way, just a bit odd.
[00:16:11] <_methods> so you have toolholders that work correctly?
[00:16:15] <zeeshan> no
[00:16:19] <zeeshan> i dont
[00:16:21] <_methods> ahhhhhh
[00:16:36] <zeeshan> this is the first time a tool holder has been insdie this machine over 5 years
[00:16:40] <zeeshan> :D
[00:16:46] <PetefromTn_> so you measured the toolholder without the pullstud and with the pullstud and without the pullstud it goes in deeper?
[00:16:47] <_methods> so the dist it's out is the same no matter if you have pullstud in or out
[00:17:02] <zeeshan> PetefromTn_: yes without pull stud
[00:17:04] <zeeshan> it goes in 3 thou deeper
[00:17:05] <zeeshan> 3-4 thou
[00:17:16] <PetefromTn_> then something is obviously wrong
[00:17:18] <zeeshan> im using stacked up feeler gauges so there is slight error in measurement
[00:17:19] <_methods> yeah
[00:17:23] <_methods> your holder is wrong
[00:17:26] <PetefromTn_> it should draw up more
[00:17:47] <zeeshan> methods i think you missed this part
[00:17:47] <PetefromTn_> probably the pullstud is wrong or there is something wrong with the drawbar
[00:17:49] <zeeshan> i posted this:
[00:18:01] <zeeshan> https://www.flickr.com/photos/128539016@N05/14996196844/
[00:18:04] <zeeshan> there is an adjustment
[00:18:13] <andypugh> Ah, sorry, I thought the 3 thou was the difference in clearance between a good tool and a bad tool. Are you saying you have no good tools?
[00:18:22] <zeeshan> andypugh: no
[00:18:30] <_methods> you have the wrong taper
[00:18:36] <PetefromTn_> he just got tools and studs
[00:18:41] <zeeshan> #40 is all the same methods
[00:18:51] <PetefromTn_> and is not sure the studs are the right ones for the machine
[00:18:54] <zeeshan> im not trying to argue here
[00:18:59] <zeeshan> but the only pull stud
[00:19:02] <zeeshan> that has a diameter close to what i need
[00:19:04] <zeeshan> is .996
[00:19:07] <PetefromTn_> 40 taper is 40 taper
[00:19:10] <_methods> pullstud is not your problem
[00:19:11] <zeeshan> all the others are .75" in diameter
[00:19:18] <_methods> you have the wrong toolholder
[00:19:19] <zeeshan> so it'd fall right out
[00:19:28] <zeeshan> _methods this is a conversion pull stud
[00:19:36] <_methods> the pullstud is not your problem
[00:19:37] <zeeshan> that is supposed to allow you to run cat40 tools
[00:20:29] <PetefromTn_> have you checked the bellvilles stack on the drawbar for any cracked bellevilles? what kind of adjustment is there?
[00:20:42] <zeeshan> pete apparently you can turn that alley key
[00:20:46] <zeeshan> to adjust the height
[00:20:52] <zeeshan> of where the pull stud bottoms out
[00:21:01] <zeeshan> socket head cap screw i mean
[00:21:12] <PetefromTn_> I would adjust until it seems like the tool is properly seating
[00:21:16] <zeeshan> You'll need a depth mike and a special tool to adjust the tool gripper fingers (search this forum for a couple of solutions for that - it basically involves a long-reach hex wrench inside a giant straight-blade screwdriver).
[00:21:20] <PetefromTn_> then put a long bar in a holder
[00:21:21] <andypugh> It is worth trying to figure out what iw wrong where. But pragmatcally you are ging to end up skimming a bit off of the tooholders or pull-studs to get the knob nearer the gauge line.
[00:21:39] <zeeshan> skimming the pull studs would be the easiest
[00:21:45] <PetefromTn_> and grab it and try to wiggle the tool when it is locked in...
[00:22:05] <zeeshan> PetefromTn_: i dont get you
[00:22:10] <zeeshan> wahtcha mean
[00:23:40] <PetefromTn_> I mean that you need to adust it until the tool seats fully and your un-knob equipped tool inserted goes in less deep than a complete tool with pullstud and then once you think you have it right put a long bar of thick steel in the holder and try to rip the toolholder out of the machine to ensure it has fully seated and will not come out before you try to do any cutting tests.
[00:23:53] <anonimasu> zeeshan: I can take a pic of the tool also.
[00:23:54] <andypugh> I think he is suggesting a more pleasant alternative to what I do when my spindle gets hot and the tool sticks, which is put a crowbar in the gap between the flange and the spindle and pull the holder down against the bellevilles.
[00:23:57] <anonimasu> it's not so special
[00:23:57] <anonimasu> :)
[00:25:09] <zeeshan> PetefromTn_: okay like hold a bar in the er collet
[00:25:16] <zeeshan> trying to basically simulate cutting force
[00:25:20] <zeeshan> so it doesnt blow up in my face :)
[00:25:33] <PetefromTn_> yeah but after you have it as good setup in there as you can and think it is right..
[00:25:41] <zeeshan> see this is a bit risky adjusting this
[00:25:44] <zeeshan> cause if i go overkill
[00:25:49] <zeeshan> instead of 3-4 thou
[00:25:51] <zeeshan> i go 6 though
[00:25:54] <zeeshan> this shit will get jammed in there
[00:25:56] <zeeshan> and impossible to remove
[00:26:01] <zeeshan> thou
[00:26:06] <andypugh> I don’t think it will
[00:26:09] <PetefromTn_> the danger here is that if the pullstud is not fully seated it can FEEL like it is holding but may just be barely holding..
[00:26:20] <zeeshan> well wouldnt it be obviously?
[00:26:22] <zeeshan> obvious?
[00:26:24] <zeeshan> cause i have the keys out
[00:26:29] <zeeshan> so i should not be able to spin it
[00:26:30] <andypugh> There should actually be quite a lot of “spare” pull in the drawbar.
[00:26:31] <zeeshan> like these guys were saying
[00:26:45] <zeeshan> ah andypugh.
[00:26:56] <anonimasu> it shouldnt stick in the taper anyway
[00:27:00] <anonimasu> that's a different problem
[00:27:35] <PetefromTn_> make sure also that the single drive dog you have is not contacting the holder on the inside that can tweak the holder sideways in the taper...
[00:27:48] <zeeshan> pete iremoved em both
[00:27:49] <zeeshan> for this test
[00:27:49] <andypugh> If the drawbar is practically fully-retracted when the taper touches, is there any tension left in the belleville stack?
[00:27:58] <PetefromTn_> for instance my Cincinatti the holder only goes in one way even tho it appears that it can go in either way
[00:28:06] <zeeshan> andypugh: i dont have access to the belleville stack :(
[00:28:33] <anonimasu> if you adjust it too much it will drop the tool

[00:28:55] <andypugh> I wasn’t suggesting checking, I was merely pondering the situation.
[00:28:57] <zeeshan> PetefromTn_: id be backing off the adjustment
[00:28:57] <PetefromTn_> if you put mine in the wrong way it will tweak it sideways and apparenlty it will wedge itself in the spindle and it is a real bitch to get it out...
[00:29:03] <zeeshan> so the top of the pull stud doesnt bottom out
[00:29:24] <_methods> PetefromTn_: yes it does suck
[00:29:38] <_methods> pain in the ass gettin stuck tools out like that
[00:29:48] <PetefromTn_> luckily a friend told me about this and I am very careful to make sure I put tools in the right way.
[00:29:58] <andypugh> PetefromTn_: Why not shorten the dogs so that can’t happen?
[00:30:01] <zeeshan> https://www.flickr.com/photos/128539016@N05/16023467657/
[00:30:04] <zeeshan> only can find this damn pic.
[00:30:07] <_methods> yeah i depress the drawbar release then i put it in and spin both ways
[00:30:11] <_methods> then release
[00:30:13] <PetefromTn_> its not about how short they are..
[00:30:15] <zeeshan> you can see the witch's hat
[00:30:24] <_methods> it will go in further when its in the right orientation
[00:30:30] <zeeshan> PetefromTn_: i am planning to put the keys in
[00:30:31] <PetefromTn_> one dog is closer to the centerline than the other one
[00:30:36] <zeeshan> only after the tool is seated correctly
[00:30:46] <PetefromTn_> good idea
[00:30:54] <zeeshan> it wouldnt even go on right now
[00:30:58] <zeeshan> cause the distance is wrong :P
[00:31:05] <PetefromTn_> I have actually considered modifying my spindle dogs and toolchanger pawls so it does not matter...
[00:31:06] <zeeshan> damn non symmetric cat40
[00:31:22] <andypugh> PetefromTn_: Yes, so you _could_ shorten one dog (radially) so that the tools fit either way.
[00:31:33] <zeeshan> tell me what to do guys!!!
[00:31:33] <zeeshan> adjust
[00:31:38] <zeeshan> or cut the retention knob !!
[00:31:39] <zeeshan> :P
[00:31:56] <andypugh> if all the knobs are the same, then probablu adjust.
[00:32:00] <PetefromTn_> I would adjust it carefully maybe a quarter turn and record which way and how far so you can put it back
[00:32:11] <zeeshan> well i have a long depth mic
[00:32:14] <zeeshan> i can measure current position
[00:32:20] <zeeshan> and adjust it so i move it 5 thou
[00:32:31] <zeeshan> (differnce is 3-4 thou)
[00:32:42] <PetefromTn_> did the new pullstud conversion come with any instructions?
[00:32:43] <zeeshan> man
[00:32:45] <zeeshan> now that i think about it
[00:32:50] <zeeshan> shouldnt there _always be bloddy clearance
[00:33:02] <zeeshan> @ the top of the pull stud
[00:33:05] <zeeshan> PetefromTn_: no

[00:33:14] <zeeshan> its hard as hell
[00:33:16] <zeeshan> so might be a pain to machine.
[00:33:32] <PetefromTn_> you would need to grind them if you did.
[00:33:41] <PetefromTn_> pullstuds are hard as shit...
[00:33:42] <zeeshan> i have cvd inserts
[00:33:47] <zeeshan> that might be able to touch it
[00:33:56] <zeeshan> but i much rather adjust
[00:34:01] <zeeshan> then f around wit hthis
[00:34:17] <zeeshan> im really glad you guys caught the fact it wasn't seated right
[00:34:21] <andypugh> I would expect the drawbar to have 2mm “spare” travel at least. But then I know nothing about them.
[00:34:21] <zeeshan> i was gonna try to mill something lol
[00:35:10] <PetefromTn_> that pullstud is so different from typical if it is even close to going in and locking down it is hard to believe it is not the right size... you probably just need to adjust. Are you sure that hex key hole in the stud is not larger than the screw up inside the spindle?
[00:35:22] <zeeshan> PetefromTn_: exactly man!
[00:35:28] <zeeshan> scientific deduction
[00:35:28] <zeeshan> hahaha
[00:35:39] <zeeshan> with the gripper closed
[00:35:44] <zeeshan> its like .850-.8"
[00:35:53] <zeeshan> if you look at all the cat40 or bt40 pull studs on mari's website
[00:35:55] <zeeshan> theyre all smaller
[00:36:01] <zeeshan> so they'd all just fall out
[00:36:24] <PetefromTn_> mine don't look ANYTHING like that nor do the HAAS ones I am used to.. it would certainly fall out if that is what the original stud looks like
[00:36:50] <anonimasu> the hex hole is a lockscrew for the whole puller
[00:36:58] <anonimasu> then there are - - slots around it for adjusting
[00:36:59] <zeeshan> http://www.maritool.com/images/RK71123.jpg
[00:37:32] <_methods> i thought you were trying to put a NMTB 40 in there lol
[00:37:48] <_methods> so that is just a regular cat40 tool holder?
[00:37:50] <PetefromTn_> I am kinda surprised that your machine does not have a label showing what kind of pullstud it uses
[00:38:02] <PetefromTn_> mine does
[00:38:14] <CaptHindsight> zeeshan: try spreading a small thin drop on some paper and cover it with clear film to see how it cures

[00:38:47] <PetefromTn_> methods apparently his machine uses an iso40 taper and he wants to use cat40 holders so he is using a conversion pullstud
[00:39:10] <zeeshan> andypugh: those are the correct tool holders
[00:39:21] <andypugh> And cheaper than your pullstuds…
[00:39:43] <zeeshan> andypugh: the main reason i didnt buy sk40 tools was
[00:39:46] <zeeshan> most of my tooling is inches.
[00:39:49] <zeeshan> like shell mills etc
[00:39:55] <zeeshan> end mills, indexable end mills
[00:40:01] <_methods> yeah that pullstud with the bluing made it look like a nmtb tool holder

[00:46:51] <andypugh> http://www.tools-n-gizmos.com/specs/Tapers.html
[00:47:43] <andypugh> It might be that the CAT hoders are 3mm too long.
[00:47:58] <zeeshan> yea there is definitely a difference between tool hegihts
[00:48:04] <zeeshan> but thats the purpose of this retention knob
[00:48:04] <Tom_itx> are the taper diameters the same?
[00:48:05] <andypugh> That will make a difference

[00:48:53] <zeeshan> cause the tool's not gonna fly out

[01:07:03] <furrywolf> grrrrr. what the fuck is wrong with people on craigslist? someone has been listing some solar parts I could use. I've emailed them three times, pointing out I live nearby and have cash. no haggling or anything else that might make someone not want to respond. no answer at all. they just renewed their posting AGAIN.
[01:07:31] <jdh> I've had CL responses get spam filtered
[01:08:57] <furrywolf> sounds like your spam filter is highly broken.
[01:09:43] <furrywolf> unless the replies were of the form of "DEAR CRAIGSLIST USER, I WOULD LIKE TO PROPOSE TO OFFER YOU ONE HUNDRED TWENTY THREE MILLION US DOLLARS..."

[01:17:21] <Mr_Sheesh> Some CL posters are maybe there to collect email addresses for spmming, I think

[01:20:57] <zeeshan> lol
[01:21:00] <zeeshan> i dont know wtf is going on
[01:21:01] <LeelooMinai> Maxiumum once per person:)
[01:21:11] <zeeshan> i measured 3.799, double checked my depth gauge too with gauge blocks
[01:21:25] <zeeshan> these guys are saying it should b e 3.610
[01:21:32] <zeeshan> but thats for another type of machine i guess.
[01:21:39] <zeeshan> cause if it was off by .200 , i'd REALLY know it
[01:21:40] <zeeshan> lol
[01:24:39] <zeeshan> im gonna buy sk40 tool holders
[01:24:44] <zeeshan> and try them, i think that was a good suggestion!
[01:24:46] <furrywolf> bbl, work
[01:25:30] <PetefromTn_> yeah I would do that.. just to be sure and safe. a toolholder is relatively cheap a new spindle or drawbar pawls is expensive
[01:25:38] <zeeshan> yea PetefromTn_
[01:25:48] <zeeshan> and what it will also allow me to do is
[01:25:51] <zeeshan> if it works well w/ the sk40
[01:25:58] <zeeshan> it means i need to modify my pull studs
[01:26:07] <zeeshan> and itll give me an idea of by how much
[01:26:20] <PetefromTn_> sure
[01:26:43] <_methods> did you call or email mikron?
[01:26:46] <zeeshan> yea
[01:26:48] <zeeshan> they dont give a crap
[01:27:01] <_methods> they wouldn't tell you what tool holder and pull stud?
[01:27:07] <zeeshan> nope
[01:27:09] <zeeshan> wont even respond
[01:27:10] <_methods> wow
[01:27:20] <zeeshan> _methods it has to be this pull stud
[01:27:23] <zeeshan> ! :D
[01:27:38] <zeeshan> all the sources ive seen where theyre selling tools
[01:27:45] <zeeshan> they all advertise "iso40 din2080"
[01:27:53] <zeeshan> din2080 has to use an ott-groove style pull stud
[01:28:01] <zeeshan> its the only style that is avaiable with a diameter close to 1"

[01:37:13] <zeeshan> if it doesnt come out
[01:37:16] <zeeshan> at least its gripped correctly
[01:37:17] <PetefromTn_> oh like I said with the leverage bar
[01:37:23] <zeeshan> yes
[01:37:35] <PetefromTn_> yeah I would recommend it before you try any cutting
[01:37:36] <zeeshan> pry bar that thing
[01:37:38] <zeeshan> with 2 copper shims
[01:37:44] <zeeshan> so i dont own the tool or the spindle face
[01:37:51] <PetefromTn_> no
[01:38:04] <PetefromTn_> don't wedge anything between the tool and the spindle face
[01:38:08] <zeeshan> aw
[01:38:11] <zeeshan> but its the easiest!
[01:38:12] <PetefromTn_> you risk damaging stuff
[01:38:23] <bobo_> I still question the top shape of the pull stud---straight top side like a rod or ---shaped like a ball
[01:38:28] <PetefromTn_> I am talking about a round say 1" bar in a holder.
[01:38:41] <zeeshan> my biggest collet is 3/4"
[01:38:42] <zeeshan> :(
[01:38:53] <PetefromTn_> dog it down tight and then put the holder in the spindle and yank on the bar sticking out of the collet...
[01:38:54] <zeeshan> itll be hard to pull down on a solid piece
[01:39:01] <zeeshan> but ill try that

[02:01:57] <zeeshan-mill> pete
[02:02:01] <zeeshan-mill> when i yank on it
[02:02:09] <zeeshan-mill> i can i see it move
[02:02:13] <zeeshan-mill> but it doesnt come out
[02:02:14] <PetefromTn_> HAHAHAHA
[02:02:19] <_methods> heheh
[02:02:30] <PetefromTn_> when I yank on it I can see it move too man thats normal hehehehe
[02:02:32] <_methods> you shouldn't be able to pull it downward at all
[02:02:34] <zeeshan-mill> LOL
[02:02:52] <zeeshan-mill> ROFL i just read what i wrote
[02:03:08] <zeeshan-mill> methods is is with a lot of leverage
[02:03:09] * Tom_itx just wonders
[02:03:20] <zeeshan-mill> like if i grab the nut on the er chuck
[02:03:21] <zeeshan-mill> and pull down
[02:03:24] <zeeshan-mill> i cant move it at all
[02:03:28] <PetefromTn_> what moves man does it rock side to side?
[02:03:38] <zeeshan-mill> no
[02:03:40] <zeeshan-mill> not side to side
[02:03:45] <zeeshan-mill> it moves straight down
[02:03:49] <zeeshan-mill> i did what you told me not to
[02:03:57] <zeeshan-mill> i put a prybar between the two surfaces
[02:04:00] <zeeshan-mill> with copper in between
[02:04:05] <zeeshan-mill> its the only way i can get it to move
[02:04:14] <zeeshan-mill> i dont have enough strength to pull it with a rod.

[02:05:04] <zeeshan-mill> whats weird is
[02:05:08] <zeeshan-mill> i cant rotate the tool anymore
[02:05:19] <zeeshan-mill> its locked in there good now
[02:06:39] <PetefromTn_> I dunno what your drawbar force is but if it is in there right you should not be able to move it at all. I would definitely wait for the right type holder to get there and check it compared to your setup now before I messed with cutting anything but that is up to you.
[02:07:03] <zeeshan-mill> the thing is i dont know what the right holderis
[02:07:07] <zeeshan-mill> some say sk40 din2080
[02:07:11] <zeeshan-mill> some say iso40 din2080
[02:07:15] <zeeshan-mill> some say din69871
[02:07:17] <zeeshan-mill> its retarded
[02:07:25] <PetefromTn_> doesn't it say it somewhere on the machine or in the paperwork?
[02:07:29] <zeeshan-mill> no
[02:07:35] <zeeshan-mill> i have no manuals, i looked and looked
[02:07:40] <zeeshan-mill> i even tried contacting sellers of the machines
[02:07:42] <zeeshan-mill> theyre clueless
[02:07:43] <PetefromTn_> can you call the previous owner and ask them
[02:07:48] <zeeshan-mill> i did
[02:07:54] <zeeshan-mill> he doesnt know either lol
[02:07:56] <zeeshan-mill> i asked him for a tool
[02:07:59] <Tom_itx> _methods, have you used HSMWorks?
[02:07:59] <zeeshan-mill> hes like he has none
[02:08:01] <_methods> wow mystery machine lol
[02:08:07] <_methods> no i have never used it
[02:08:11] <_methods> i use mastercam or gibbscam

[02:08:57] <PetefromTn_> is there anything stamped into the spindle face?

[02:11:51] <PetefromTn_> wonder if that is toolholder length with pullstud and max tool weight or something
[02:12:13] <_methods> well i'd try hitting a local tool rep
[02:13:07] <_methods> i'd go to a local machine shop and ask them who the most knowledgeable tool rep is
[02:13:14] <_methods> hit several up
[02:13:24] <_methods> in no time flat you'll know who to talk to
[02:13:46] <_methods> or your local sandvik rep
[02:13:49] <bobo_> petefromTn -does / did your mill use spindle gage line toref tool length ? prob before conv-linux
[02:13:57] <_methods> he'll know the best tool guy in the area
[02:14:22] <zeeshan-mill> man this is definitely the right pull stud
[02:14:30] <zeeshan-mill> i measured the distance from the grip to the flat face
[02:14:34] <zeeshan-mill> and its pretty damn close.
[02:16:21] <zeeshan-mill> im thinking of trying this
[02:16:29] <zeeshan-mill> take a tool holder, loosely mount the pull stud
[02:16:41] <zeeshan-mill> lock it in the tool holder
[02:16:48] <zeeshan-mill> unscrew the tool holder from the stud
[02:16:51] <zeeshan-mill> and see wtf is up
[02:18:16] <bobo_> just thread a rod for pull stud
[02:18:36] <zeeshan-mill> ok there is a pull stud in there
[02:18:41] <zeeshan-mill> i can move it up.
[02:20:36] <bobo_> diff between "L" shape vers "C" pulling fingers ?
[02:21:40] <zeeshan-mill> whatcha mean
[02:23:16] <bobo_> L shape C shape not closeing on stud because of in a tube
[02:24:04] <bobo_> stud shape = ball or straight side
[02:27:36] <bobo_> you may have small up down if not pulling against bottom of spindle face

[02:58:17] <furrywolf> I want an auto tool setter for my new machine... probably do something stupidly trivial like just mount a microswitch facing upwards.

[03:04:22] <zeeshan> LeelooMinai: i am dissapointed in you
[03:04:28] <zeeshan> you're on irc when you should be working on your machine!
[03:04:36] <PetefromTn_> looks like the pullstud is secured at least in there.
[03:04:43] <zeeshan> PetefromTn_: is that normal man
[03:04:47] <zeeshan> when i yank on it by hand i cant move it
[03:04:48] <PetefromTn_> what?
[03:04:48] <zeeshan> but when i pry
[03:04:51] <zeeshan> it moves
[03:05:04] <PetefromTn_> dunno never pried on my toolholder against the spindle face before
[03:05:06] <zeeshan> haha
[03:05:09] <LeelooMinai> Right, well, I need to wait for money to move on
[03:05:14] <zeeshan> do you like my foil technique
[03:05:28] <PetefromTn_> you're one crazy dude
[03:05:42] <zeeshan> this is the problem man
[03:05:49] <zeeshan> working on cars, then working on cnc machines
[03:05:51] <zeeshan> not a good idea!
[03:06:52] <PetefromTn_> it seems like when you DID pry on it you were pulling against the bellevilles and the cutter holder was in position at least it LOOKS in position like mine does when it is loaded.
[03:07:24] <PetefromTn_> when you insert the tool and release the drawbar tension do you feel it pull the holder up and lock down in position?'
[03:07:45] <zeeshan> yes
[03:07:53] <zeeshan> im gonna make a video of it

[03:10:18] <PetefromTn_> http://tricities.craigslist.org/tls/4855239657.html this looks interesting...
[03:10:53] <Connor> PetefromTn_: Look at the third picture....
[03:11:11] <PetefromTn_> yeah
[03:11:26] <LeelooMinai> It's a wooden lathe:)
[03:11:32] <PetefromTn_> yeah I know
[03:11:52] <PetefromTn_> was thinking for the price the parts would be worth just buying it to take it all apart LOL
[03:12:10] <furrywolf> purchasing a non-garbage camera would pay for itself on the first thing he posts on craigslist.
[03:12:29] <LeelooMinai> Maybe the red is to hide it's from wood...
[03:13:36] <PetefromTn_> looks like it has linear guideways and ballscrews/steppers/ controller, etc. etc. It may be a piece of shit but if it works at all it might be worth $200.00 or so
[03:15:43] <furrywolf> gah! evil and scary! on the truck I'm working on, the battery master switch disconnects the GROUND. it's a 24v system with 12v loads tapped off the first battery. If you turn off the battery master switch while any of the 24v loads are on, ground will float up to 24v, and the 12v system will instead be a -12v system.
[03:17:03] <zeeshan> PetefromTn_:
[03:17:06] <zeeshan> its not automatic tool change
[03:17:09] <zeeshan> its all drawbar based
[03:17:16] <zeeshan> and in that you just yank that shit down! :P
[03:17:33] <zeeshan> and ive never had the keys out before
[03:17:48] <PetefromTn_> heh
[03:17:58] <zeeshan> the only place i used cat40 was at work
[03:18:07] <zeeshan> like 5 years ago
[03:18:14] <zeeshan> in that it was ATC
[03:18:17] <zeeshan> so never got a hand feel for it
[03:18:55] <PetefromTn_> you never loaded tools or changed cutters?
[03:19:32] <zeeshan> manually -- only w/ drawbar
[03:19:33] <zeeshan> not power drawbar
[03:20:01] <PetefromTn_> ok
[03:20:32] <zeeshan> when i look at this
[03:20:34] <zeeshan> vid
[03:20:37] <PetefromTn_> really bites ass you can't determine what the right holder is
[03:20:48] <zeeshan> it looks exactly how it looked like when the atc loaded up the tool
[03:20:51] <zeeshan> it clicks up
[03:21:05] <zeeshan> https://www.youtube.com/watch?v=6YalZU0TUpE
[03:21:09] <zeeshan> sorry its a bit blurry
[03:21:17] <zeeshan> i had the phone between my chin and cchest
[03:21:17] <zeeshan> haha
[03:21:43] <PetefromTn_> LOL I have done that before
[03:22:09] <PetefromTn_> honestly man it looks right to me...but I don't like how you were able to pry it down were you cranking on it a lot or was it easy..
[03:22:23] <zeeshan> about 40 lb of force
[03:22:33] <zeeshan> but with a 14" prybar
[03:22:43] <zeeshan> PetefromTn_: when i pried
[03:22:48] <zeeshan> it felt springy
[03:22:57] <zeeshan> so i really think i was stretching the spring washers
[03:23:07] <PetefromTn_> yeah you were pulling down the bellevilles
[03:23:07] <zeeshan> like asap my force amount decreased
[03:23:09] <zeeshan> it sprung back
[03:24:08] <PetefromTn_> so now once it is in there and locked down it does not have any side to side play and it feels like it is fully seated you are saying.. you might have it good then. It certainly looks right in that video you just posted.
[03:24:53] <zeeshan> yes no side to side play
[03:25:02] <zeeshan> but i can still spin it by hand
[03:25:05] <zeeshan> which doesnt feel right
[03:25:06] <PetefromTn_> if you feel confident that it is locked down and will not pull out maybe make some real light side cuts on a piece of aluminum or something to test how it sounds if you do not intend to buy the correct tool to test with or cannot determine what the correct tool is to biu one
[03:25:11] <zeeshan> and the blueing shows its not seated
[03:25:26] <PetefromTn_> Oh shit so you can actually turn it?
[03:25:27] <zeeshan> honestly i'd love to buy the real one
[03:25:36] <zeeshan> but i dont have the money to buy 5 diff kinds
[03:25:39] <zeeshan> that are potentials
[03:26:00] <PetefromTn_> if it was seated you sure as hell could not turn it...
[03:26:04] <zeeshan> yea if i give it like 15 ft-lb of torque
[03:26:06] <zeeshan> i can spin it
[03:26:23] <PetefromTn_> be careful you can score your spindle bore that way
[03:26:33] <PetefromTn_> gall it
[03:26:48] <zeeshan> eek
[03:26:52] <zeeshan> okay ill stop spinning it :P
[03:27:26] <PetefromTn_> yeah if the tool is seated I seriously doubt you could turn the spindle by hand even without the drive dogs engaged..

[03:27:55] <PetefromTn_> y
[03:28:52] <PetefromTn_> my pal art and I have been brainstorming on a way to make a pneumatic tubular drawbar style 5c collet closer for the CNC lathe
[03:29:15] <zeeshan> at least you'll know what tool holder to run in it!!! :P
[03:29:22] <PetefromTn_> hehe
[03:29:34] <PetefromTn_> got several ideas about how to do it
[03:29:52] <PetefromTn_> really want to be able to set collet pressure with a pneumatic regulator for consistency

[03:33:40] <zeeshan> i think i understand what you were saying bobo.
[03:33:46] <zeeshan> the hooks come up
[03:33:52] <zeeshan> and push it against the adjustment washer
[03:33:54] <PetefromTn_> its funny you mention that honestly the lathe drawbar operation is quite similar to how a lot of benchtop CNC mills drawbars work
[03:33:59] <bobo_> yes
[03:34:00] <zeeshan> when you release, the push against the other notch
[03:34:03] <zeeshan> to release the tool
[03:34:30] <zeeshan> so if i add a washer.
[03:34:42] <zeeshan> between the adjustment washer and top of pull stud
[03:34:48] <zeeshan> shouldnt it clamp more? :P
[03:34:50] <zeeshan> er.
[03:35:00] <zeeshan> no, it should be less distance
[03:35:12] <zeeshan> wait this doesnt make sense anymore to me :(
[03:35:15] * zeeshan is thinking out loud
[03:35:27] <PetefromTn_> have you tried to adjust the clamp setup while recording the original position?
[03:36:10] <zeeshan> no
[03:36:12] <zeeshan> it needs a special tool
[03:36:30] <zeeshan> basically a hollow pipe with two notches at the end
[03:36:40] <zeeshan> and you stick a 4mm allen key through the center
[03:37:15] <zeeshan> i know this much that i tried to even add 6 thou of shim between the top of the retention knob and the adjustment screw to simulate a longer length
[03:37:18] <zeeshan> and it made things worse

[03:42:28] <bobo_> you know ---under the witch hat ---hyd stuff . not a quick thing to do------also need the tool
[03:42:52] <zeeshan> i dont see it through the inspection slot :P
[03:44:42] <zeeshan> bobo_: that witch hat is not easy to remove easier
[03:44:47] <zeeshan> easier = either

[03:47:08] <zeeshan> im thinking also to definitely check the belleville washers
[03:47:18] <zeeshan> cause it makes no sense that i could move the tool holder like that
[03:47:20] <zeeshan> with just a prybar
[03:48:56] <PetefromTn_> I dunno I seem to recall reading that the cat40 belleville pressure is usually around 8-900 lbs

[06:07:47] <zeeshan> finally found a pic of the cnc
[06:07:49] <zeeshan> w/ the tools.
[06:07:55] <zeeshan> i have the correct retention knob
[06:10:12] <PetefromTn_> whats strange is they apparently make a bunch of different flavors of that same basic machine larger and smaller with different options but that one is hard to find any information on... perhaps if you were in eu you might have better luck
[06:10:26] <zeeshan> i really think its a translation issue
[06:10:35] <zeeshan> i couldnt find anything aboutr the servos either
[06:10:42] <zeeshan> when i searched some german keywords
[06:10:45] <zeeshan> i found it after a couple hours
[06:11:00] <PetefromTn_> my lathe is similar
[06:11:05] <PetefromTn_> it is made in Canada
[06:11:28] <PetefromTn_> and the electronics were a combination of anilam and HHroberts/Standard Moderns own flavor
[06:11:50] <PetefromTn_> at least parker servomotor has information on the motors
[06:12:13] <PetefromTn_> but they basically told me they would not even be able to make another spindle motor for it even if I could afford it anymore
[06:12:14] <zeeshan> did you contact standard modern?
[06:12:16] <zeeshan> or they dont exist anymore
[06:12:26] <PetefromTn_> yeah they exist and they tried to help
[06:12:35] <PetefromTn_> but they only had basic information
[06:13:12] <PetefromTn_> the good news is I had planned to basically replace everything anyways
[06:13:17] <PetefromTn_> so it is not a big deal
[06:13:34] <PetefromTn_> but if I had wanted to keep the original parts if they were still there it might have been a bitch
[06:13:46] <PetefromTn_> I still do not know what the hell kind of toolpost it had on it
[06:14:02] <PetefromTn_> its a really big block base with an air line going into it
[06:15:51] <PetefromTn_> it has a really large stud that is like permanently in the block that kinda looks like the big bolt that goes down thru one of the aloris style quick change tool posts
[06:16:03] <PetefromTn_> but it seems way too big for that.
[06:16:05] <zeeshan> you dont wanna reuse the servos?
[06:16:10] <PetefromTn_> no
[06:16:15] <zeeshan> why
[06:16:17] <PetefromTn_> I am selling the X one
[06:16:36] <PetefromTn_> because they are apparenlty resolver based and I don't want to try to mess with that
[06:16:47] <zeeshan> pcw has a card for that
[06:16:48] <zeeshan> :P
[06:16:58] <PetefromTn_> I am going to get new servos and drives that match and come with cabling and whatnot all matched together
[06:17:57] <PetefromTn_> I honestly believe that it saved me a TON of trouble on the Cincinatti and everything is brand new so no worries about it. plus it is cheaper to replace if it should eventually fail.
[06:18:11] <zeeshan> thats true
[06:18:18] <zeeshan> i went with amc drives for that reason
[06:18:22] <zeeshan> will work w/ any type of servo
[06:18:30] <PetefromTn_> thats good
[06:18:31] <zeeshan> too bad my Z one isn't as powerful
[06:18:33] <zeeshan> as i thought it would be
[06:18:34] <zeeshan> :(
[06:18:59] <zeeshan> man im so bummed out

[06:19:04] <zeeshan> i really wanted to make some chips today
[06:19:44] <PetefromTn_> I know how you feel
[06:19:58] <PetefromTn_> I don't even have a lathe here anymore to use and it is killing me
[06:20:00] <zeeshan> well look on the bright side
[06:20:06] <zeeshan> at least i didnt go mil lsomething
[06:20:07] <PetefromTn_> I cannot wait to get this thing working
[06:20:14] <zeeshan> and have a tool holder blow up in my face
[06:20:19] <zeeshan> which took out my spindle with it
[06:20:19] <zeeshan> haha
[06:20:29] <zeeshan> how long do you think your retrofit will take
[06:20:37] <PetefromTn_> exactly that would suck bad
[06:20:45] <PetefromTn_> Oh I dunno man
[06:20:54] <PetefromTn_> once I get all the parts here maybe a month or two
[06:21:02] <PetefromTn_> depending on how busy I am with other work
[06:22:56] <zeeshan> shit takes a while man :P
[06:23:12] <zeeshan> enough retrofits for me
[06:23:21] <zeeshan> (after one lol)
[06:23:34] <PetefromTn_> it sure does
[06:23:47] <PetefromTn_> I am hoping the lathe will go quicker because it is simpler
[06:23:48] <zeeshan> i think since i have a somewhat working controller
[06:23:52] <PetefromTn_> and easier to get to the parts
[06:23:54] <zeeshan> i could do more machines easier
[06:24:32] <zeeshan> i remember you saying
[06:24:34] <zeeshan> that you need ball screws
[06:24:46] <PetefromTn_> just the Z
[06:24:48] <zeeshan> does that mean you also need the ball nuts?
[06:24:50] <zeeshan> ah
[06:24:58] <PetefromTn_> already bought the angular contacts
[06:24:59] <zeeshan> youre so lucky!
[06:25:01] <zeeshan> X is done!!
[06:25:01] <zeeshan> :D
[06:25:21] <zeeshan> i would love to see how they did it
[06:25:23] <PetefromTn_> and I need to get a little sketch drawn up for the Z so I can get it ordered with machined ends
[06:25:37] <PetefromTn_> what do you mean
[06:27:37] <zeeshan> how they managed
[06:28:01] <zeeshan> to put the ball nut within the cross slide
[06:28:06] <PetefromTn_> you understand this machine was born a CNC lathe right..
[06:28:12] <zeeshan> yea
[06:28:15] <zeeshan> thats why i wanna know how they did it
[06:28:28] <zeeshan> your lathe is very similar
[06:28:33] <zeeshan> to a manual standard modern lathe
[06:29:12] <PetefromTn_> well the screw is under the cross slide slab and goes out the back side of the machine. The motor is facing the rear of the machine underneath the cross slide casting
[06:29:55] -!- mttr has quit [Ping timeout: 252 seconds]
[06:29:55] <PetefromTn_> it is actually quite similar to the 12x36 I had in the basic setup just much larger and heavier
[06:30:00] <zeeshan> http://www.machineco.com/Lathe_14inX40in_Standard_Modern.jpg
[06:30:06] <zeeshan> this it?
[06:31:07] <zeeshan> http://www.moderntool.com/products/images/5892/C0636A.jpg/
[06:31:09] <zeeshan> looks very similar to that
[06:31:13] <zeeshan> the manual wversion
[06:31:25] <PetefromTn_> http://www.hhrobertsmachinery.com/used-cnc-lathes/Used_Standard_Modern_cnc_lathe.jpg
[06:32:03] <PetefromTn_> that is pretty much what the machine looks like or will look like I am missing some of the rear sheet metal tho
[06:32:38] <toastydeath> most more recent lathes have the sheet metal
[06:34:53] <PetefromTn_> https://www.youtube.com/watch?v=1d_kDV2oGKg this is the next size up machine to mine but it is the same sheetmetal etc..
[06:35:19] <PetefromTn_> mine came with the fullish enclosure but the backsplash piece is missing when I got it.
[06:35:32] <zeeshan> how much did you pay for this!
[06:35:38] <zeeshan> i like it
[06:35:47] <PetefromTn_> not much heh
[06:37:01] <PetefromTn_> yeah I really like it too... kind of an overgrown 12x36 but with built in chip and coolant troughs and bigger motors etc.
[06:37:43] <PetefromTn_> LOL I'm wrong
[06:38:10] <PetefromTn_> actually that video I just posted is the EXACT same machine I have 14x40CNC HH roberts/Standard MOdern
[06:42:49] <PetefromTn_> I can't wait to see mine running like that.
[06:43:45] <PetefromTn_> I think once I get it working and get the collet closer setup in there it will be a good all around CNC lathe that can be run like the manual lathe I had as well as some decent production work once I get a tool turret mounted and working down the road

[07:00:04] <PetefromTn_> https://www.youtube.com/watch?v=uMiNn4ph9Js in most respects my machine will be sorta like this HAAS Tl1 I think
[07:00:12] <zeeshan> i wonder if this OTT
[07:00:15] <zeeshan> in the part number of the cylinder

[07:03:34] <zeeshan> yep
[07:03:34] <zeeshan> thats it
[07:03:55] <bobo_> is the hat made from a almost foam like plastic ?
[07:04:34] <zeeshan> no

[07:13:42] <zeeshan> you know one thing i did not try is

[07:35:25] <zeeshan> i was doing the measurement wrong.
[07:35:35] <zeeshan> it shoulda been measured in the unclamped position.
[07:37:44] <bobo_> zeeshan I think you need hyd pressure to remove the fingers adj nut/screw
[07:38:27] <bobo_> but not the witch hat
[07:38:47] <zeeshan> yea
[07:38:51] <zeeshan> dude i think i know whats wrong
[07:38:53] <zeeshan> im estimating here
[07:39:08] <zeeshan> the stroke is 5.5 mm = .2165 "
[07:39:16] <zeeshan> i measured at clamped position 3.799
[07:39:27] <zeeshan> that works out to 3.582"
[07:39:35] <zeeshan> the spec is 3.610 +/- .010
[07:40:00] <zeeshan> something is up :)
[07:41:35] <bobo_> missprint ? +_ .020
[07:41:59] <zeeshan> no
[07:42:20] <zeeshan> each thou makes a big diff
[07:42:22] <zeeshan> in the clamping load
[07:42:35] <zeeshan> im just trying to work out in my head , since i am lower
[07:42:47] <zeeshan> what would be the effects :P
[07:43:19] <zeeshan> shrug im too tired to think :)

[13:14:41] <MrSunshine> hmm only options for warped plywood in cnc is vacuum or screw it down everywhere ?
[13:14:43] <MrSunshine> :/
[13:18:35] <archivist> or follow the warped shape
[13:18:55] <MrSunshine> kinda hard =)
[13:19:06] <MrSunshine> i hate plywood
[13:19:08] <MrSunshine> its never straight
[13:19:20] <archivist> there is a probing thing someone did
[13:19:40] <archivist> was for pcb work
[13:20:06] <TekniQue> and height control seems ubiquituous in plasma cutters
[13:20:23] <TekniQue> to follow metal plates that aren't perfectly straight
[13:21:49] <MrSunshine> well in plasma you just sense the arc voltage to follow at height .. kinda hard to do that on wood :P
[13:22:20] <archivist> you probe the plane and add the error from that
[13:22:47] <archivist> should be on the wiki or in the docs somewhere
[13:24:49] <_methods> you can use a follower cone too

[16:08:11] <zeeshan> (automotive does this)

[16:08:30] <zeeshan> they put all the parts in a blast chamber
[16:08:32] <archivist> is there is a reverse attempt first
[16:08:41] <zeeshan> will it with gas and do a controlled explosion
[16:08:44] <zeeshan> it burns off all the bars
[16:08:46] <zeeshan> *burrs
[16:08:50] <zeeshan> due to surface area - volume ratio
[16:09:07] <archivist> some to a chemical dissolve of it

[16:58:27] <PetefromTn_> I am needing to get setup with a vacuum fixture to make these the way I want to so I can just whip them out quickly..
[16:58:49] <PetefromTn_> trying to decide what kind of pump and where locally I might be able to buy some vacuum thin hose and fittings etc.
[16:59:07] <PetefromTn_> I have some push loc fittings I plan to use that are rated for vacuum
[16:59:17] <PetefromTn_> gotta find a reasonably priced pump etc.
[16:59:45] <PetefromTn_> there is one on the local craigslist for a good price but who knows what is has been thru
[17:01:00] <PetefromTn_> my compressor is more than large and fast enough to use a venturi but I am not sure I want to listen to it running the whole time.
[17:02:16] <Connor> How big of a surface area is the part ?
[17:02:32] <Connor> and, are you going to do multiple parts on one fixture ?
[17:02:39] <PetefromTn_> yes and yes
[17:02:50] <PetefromTn_> the part is actually perfect for a vacuum hold down setup
[17:03:04] <PetefromTn_> it has a lot of flat surface area and the only thru holes are on the perimeter
[17:03:06] <CaptHindsight> move the compressor or build a baffle around it
[17:03:17] <PetefromTn_> LOL thats not a bad idea
[17:03:28] <PetefromTn_> but honestly doesn't the venturi make a lot of noise too?

[17:15:20] <CaptHindsight> if i ran a venturi off the compressor it would probably run continuously
[17:15:50] <PetefromTn_> probably
[17:16:45] <CaptHindsight> how many cfm do you think you need for vacuum?
[17:17:04] <PetefromTn_> meh I doubt it is really critical
[17:17:19] <PetefromTn_> as long as it pulls a good seal and hold the part never tried to figure it out really
[17:18:16] <malcom2073> vacume hold-down scares me. guy at my last job had a part come loose

[17:34:41] <Rab> That Vacmagic thing takes compressed air, I guess it's using an internal vacuum venturi.
[17:34:49] <PetefromTn_> yeah it does

[17:36:40] <PetefromTn_> I suppose it would not hurt to grab that HF venturi model since it is so cheap and just try it. if it really sucks and is loud as hell just take it back and get the pump LOL
[17:37:08] <PetefromTn_> the nice thing about the venturi is that there is nothing to go wrong with it and I already have a good compressor...
[17:37:09] <CaptHindsight> I have one in a box somewhere
[17:37:27] <PetefromTn_> LOL is it that bad?
[17:38:07] <CaptHindsight> for running a small nozzle / dispense valve or similar it's ok
[17:39:04] <PetefromTn_> I was thinking a small fixture maybe say ten by ten inches holding down some 3/16 aluminum plate to cut thru and engrave on top
[17:39:31] <PetefromTn_> I have some half inch 6061 plate to make the fixture from here I was going to use
[17:39:32] <CaptHindsight> but any compressor or vacuum pump that you are going to use for >1 hour a day I'd relocate or build a baffle

[19:03:50] <PetefromTn_> I plan to make a dedicated fixture for these parts so I will be just cutting the shape and the vacuum pockets in the half inch plate
[19:04:28] <PetefromTn_> I will be holding it on top of the kurt vise so the hose fittings will be okay underneath the plate in their appropriate positions.
[19:04:50] <Tom_itx> hint: put a little screen in the vaccuum hose to keep shavings out of the vaccuum pump

[19:14:52] <PetefromTn_> honestly the sucking debris into the pump issue is something to consider
[19:15:12] <PetefromTn_> using the venturi style would make this a non issue at least from a damage standpoint
[19:15:17] <Jymmm> I thought about having a pre-heat trought, then a "bend" heat one.
[19:15:21] <CaptHindsight> I'm designing one now that works sort of like a dishwasher

[19:17:24] <CaptHindsight> in the lab we have requirements like 98C for 5 minutes then 45C for 20 and then 80C for 30 etc

[19:24:18] <PetefromTn_> nice
[19:26:03] <FinboySlick> http://www.fabiatech.com/en/product-c.php?id=301 Would something like that just plug into a PCI mesa card using a dumb PCI bridge? Would make for quite a compact system.
[19:29:30] <toast-work> marmite: a basic hvac-style vacuum pump will work
[19:30:15] <roycroft> a lot of those vacuum tables only need a shop vac
[19:30:19] <CaptHindsight> FinboySlick: look for a 2 slot PCI backplane
[19:30:29] <roycroft> and if you have a shop vac already, i would try that before buying something else
[19:30:33] <marmite> yeah shop vac makes to mutch noise :D
[19:30:42] <toast-work> shop vac works, but is much riskier
[19:30:48] <roycroft> it would at least give you a sense of how much vacuum is needed
[19:30:51] <toast-work> the vacuum isn't particularly strong and they tend to blow out
[19:30:57] <marmite> yeah i rather spend money on a pump

[20:00:07] <FinboySlick> deanputney: Hmmm... Interesting. Depending on where you get the pulses from, it might make sense if you manage to extract timing information with them.

[20:05:09] <FinboySlick> deanputney: Deterministic realtime (and forgive my gross oversimplification here) works on the principle that it knows how the cpu spends doing each step of your program. With virtualization, the cpu is running the host OS which is doing its own thing at the same time, you never know if it was busy taking care of something else and your timing is off.
[20:05:15] <CaptHindsight> deanputney: into a stepper driver? As Step pulses?
[20:05:53] <zeeshan> im giving on this mikron MACHINE!!
[20:06:14] <deanputney> hmmm, interesting
[20:06:18] <CaptHindsight> zeeshan: don't make me up there
[20:06:18] <FinboySlick> zeeshan: Please ship it to me, I'll give it a go ;)
[20:06:24] <zeeshan> lol
[20:06:24] <deanputney> FinboySlick: It's probably into a stepper driver, yeah
[20:06:47] <CaptHindsight> zeeshan: whats up with it now?
[20:07:17] <CaptHindsight> spindle issues?
[20:07:24] <FinboySlick> deanputney: Let's oversimplify... Imagine that you're just trying to drive one axis of your machine at a set speed of 40 pulses per second.
[20:07:36] <deanputney> FinboySlick: Sure.
[20:08:24] <zeeshan> yea seems like wrong tool holder
[20:08:26] <FinboySlick> deanputney: So, every 1/40 second, your CPU has to toggle one bit.
[20:08:29] <zeeshan> its a bit annoying
[20:08:34] <zeeshan> mari tool doesnt have a drawing for their own pull stud
[20:08:36] <zeeshan> i emailed him

[20:09:04] <CaptHindsight> zeeshan: do you have any that fit?
[20:09:07] <zeeshan> no
[20:09:13] <zeeshan> theyre so close to fitting
[20:09:20] <zeeshan> its likely the correct pull stud
[20:09:25] <zeeshan> er
[20:09:26] <zeeshan> wrong pull stud
[20:09:52] <CaptHindsight> I wish my problems were that easy
[20:10:04] <FinboySlick> deanputney: Now imagine that while your CPU is running the code that toggles that bit, it gets an interrupt from the Host OS because the host OS is trying to flush its TCP table (or whatever else). Your code stops mid-execution and you're now several cycle lates before the bit gets toggled.
[20:11:32] -!- Nick001-shop [Nick001-shop!~chatzilla@50.107.148.228] has joined #linuxcnc
[20:12:35] <FinboySlick> deanputney: If you just record the output of that pin, you are very very likely to record something other than a bit toggling every 1/40 seconds.
[20:14:45] <deanputney> FinboySlick: I think the idea is to intercept the data before it hits the parallel port output
[20:15:10] <FinboySlick> deanputney: The idea would be to intercept the data before there's any sort of timing involved.
[20:15:14] <deanputney> FinboySlick: so there must be some step before it writes out where it knows what it's planning to write, and we should be able to preserve that
[20:15:21] <deanputney> FinboySlick: Right. That'd be ideal.
[20:15:21] <CaptHindsight> deanputney: why would you want to record this if you van just reliably generate the same steps every time with linuxcnc?
[20:15:29] <CaptHindsight> van/can
[20:15:54] <FinboySlick> deanputney: There's another factor you might be missing here.
[20:16:33] <deanputney> CaptHindsight: The idea is to run linuxcnc on a server, basically
[20:16:36] <FinboySlick> deanputney: You can't record anything that requires feedback.
[20:17:05] <FinboySlick> deanputney: As a simple example, rigid tapping.
[20:17:12] <deanputney> FinboySlick: Right. That makes sense.
[20:17:38] <CaptHindsight> deanputney: Linuxcnc can run on a server. What makes your server different than a desktop PC?
[20:17:39] <deanputney> FinboySlick: I think that's OK for the purposes here, though.
[20:18:28] <PetefromTn_> I have a little one of those simple pressure/vacuum tanks here I wonder if I should try to use it to help with initial suck down on the parts using whatever vacuum I choose..
[20:18:34] <deanputney> CaptHindsight: We want the motion planning to happen asynchronously from the machine movement
[20:18:36] <FinboySlick> deanputney: you're faced with the same problem on the playback side.
[20:18:58] <FinboySlick> deanputney: How do you know your playback computer won't be interrupted by a fan control interrupt or what not?
[20:19:18] <CaptHindsight> deanputney: how much of it and how much time before?
[20:19:40] <deanputney> FinboySlick: I think that's less of a concern. If it's interrupted it should probably reconnect with the CNC server and regenerate the motion
[20:19:53] <deanputney> FinboySlick: It would handle that interrupt separately
[20:20:20] <CaptHindsight> deanputney: what are you actually trying to do? Whats the bigger picture?
[20:21:33] <zeeshan> http://i.imgur.com/AlIOqNo.png
[20:21:38] <zeeshan> man
[20:21:52] <zeeshan> my tool holder is off by 2mm
[20:21:57] <zeeshan> but the retention knob dimensions are correct.
[20:22:42] <zeeshan> my holder's drawing isnt completely accurate
[20:22:42] <zeeshan> :P
[20:23:00] <zeeshan> i guess i need to draw a cat40 holder
[20:23:07] <zeeshan> and try to find a drawing for this pull stud.
[20:23:29] <deanputney> CaptHindsight: The bigger picture is somewhat beyond what I'm trying to accomplish here.
[20:24:35] <deanputney> CaptHindsight: I mostly just want to get this software running on a server at the moment.
[20:25:16] <deanputney> CaptHindsight: and I'm trying to decide what the best way to do that is. It sounds like a VM might work for my purposes, but a Docker container won't, or would at least be much more problematic.
[20:25:40] <CaptHindsight> deanputney: I have mainboards that can fit into a laptop, desktop or server enclosure. What makes your PC a server?

[21:37:35] <CaptHindsight> drill holes in the flanges
[21:38:29] <LeelooMinai> Ok, so the holes are not there because the placement may be different for different machines, or there are some systems of mounting this without holes?
[21:39:01] <CaptHindsight> if your Z has enough area you could have clamps or slots hold it
[21:39:37] <CaptHindsight> http://www.automationtechnologiesinc.com/wp-content/uploads/2011/11/KL-3040A.jpg but this is the usual

[21:50:07] <CaptHindsight> looks fine
[21:50:19] <CaptHindsight> I'd probably make a clamp
[21:51:23] <LeelooMinai> A clamp would look like what exactly? Aluminum bar with holes?

[22:06:44] <CaptHindsight> thats good enough for wheel spaces the tires flex more than that
[22:07:13] <CaptHindsight> and it will still keep balance if you keep it symmetrical
[22:08:04] <furrywolf> a few thous seems pretty painfull with a 100lb tire spinning at freeway speeds...

[22:11:04] <CaptHindsight> can't you drill all the holes from one side?
[22:11:45] <CaptHindsight> you have the center hole for the hub, holes for the studs on the axle and then holes for the new studs
[22:11:47] <furrywolf> I need to machine an step on each side for the hub-centering
[22:12:26] <furrywolf> and I don't have a lathe nearly large enough to stick it in a 4-jaw chuck and tweak until running true. :)
[22:13:29] <CaptHindsight> http://c1552172.r72.cf0.rackcdn.com/386160_x800.jpg are you making this?
[22:14:08] <furrywolf> no
[22:14:43] <furrywolf> http://www.spidertrax.com/core/media/media.nl?id=2475&c=407909&h=a76ac7fc29596ef0c98c that kind
[22:15:26] <furrywolf> except in a non-standard large 6-lug pattern only used on this vehicle and nothing else, so no one sells one. :P
[22:16:11] <furrywolf> note the raised hub area in the middle, and (not visible) a matching indent on the backside, that need to be concentric.

[22:19:09] <furrywolf> I figure a 2" spacer will let me replace my current x11 tires with x15 tires with the same minimal rubbing... and a massive improvement in not sinking in the sand.
[22:20:03] <furrywolf> hrmm, found a forum posting where a shop says they'll make them for $250/pair...

[22:36:57] <furrywolf> I don't know if I can beat that price just for the aluminum and studs!
[22:37:09] asheppard is now known as sheppard
[22:37:21] <CaptHindsight> and already anodized or powder coated
[22:37:57] <CaptHindsight> pair or set of 4?
[22:38:35] -!- chillly has quit [Quit: Ex-Chat]
[22:39:16] <furrywolf> pair
[22:43:23] <furrywolf> meh, I can't afford the new tires anyway... was just inspired by someone I know doing the same on his bronco.
[22:47:36] <furrywolf> he got hummer beadlock wheels to put on his 1-ton ford axles, but the offset is way off, needing a thick spacer...
[22:50:06] <furrywolf> I'm happy with my original kill-you-if-you-don't-seat-the-lock-ring factory rims... heh

[23:16:35] <tjtr33> any ideas how to demagnetize a 52" inconel ring? ( its hairy right now, no big walker chucks nearby either )
[23:17:32] <tjtr33> hairy as in metal particle bearded
[23:18:07] <Jymmmm> smack it really really hard on the ground.
[23:18:43] <tjtr33> hmm a bit expensive and big to whack ( i actually told them that joke already )
[23:19:18] <Jymmmm> I'm not joking, and I mean to throw it on the ground in an accelerated manner.
[23:19:31] Jymmmm is now known as Jymmm
[23:19:47] <tjtr33> Jymmmm, thx but its an aerospace part , a turbine ring

[23:20:23] <Jymmm> wrap it in bubble wrap first? ~shrug~
[23:20:41] <tjtr33> anyone built a demag? i'mm thinking an old crt demag ring might eventually work
[23:21:14] <Jymmm> what size in the ring?
[23:21:21] <Jymmm> is*
[23:21:23] <tjtr33> 52" od
[23:21:32] <Jymmm> lol
[23:21:48] <tjtr33> YOU pick it up and throw it on the floor :)
[23:21:53] <Jymmm> I've never seen a degauser that large
[23:22:11] <Jymmm> I will, let me on the forklift
[23:22:21] <Jymmm> tilt forward, PLOP!
[23:22:21] <tjtr33> a plate demag could be slid over the surface
