[00:24:43] <Connor> renesis: Stay away from those.. Inductance is terrible.
[00:28:26] <Connor> renesis: see this:
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Stepper_Formulas
[00:36:30] <pfred1> a high inductance motor will have high torque but it won't be able to run high speed
[00:37:01] <pfred1> it will have too much inductive reluctance
[00:38:15] <pfred1> the best motors have a high current, and a low voltage rating
[00:39:14] <pfred1> unless you have an application where you need high torque at a low wpeed like you are doing christmas animations
[00:48:41] <renesis> connor: oh damn, yeah just the x axis scaling on the torque curves says a ton, 23 vs 24
[00:48:50] <renesis> you dont even really have to look at the curves, heh

[01:09:46] <XXCoder> good night all
[01:09:51] <pfred1> nite
[01:21:10] <zeeshan> pcw_home: is it an okay idea to use an e-stop switch in this config: when a standard e-stop NC switch is pressed, power will be taken away from the contactors killing power to drives etc. to tell linuxcnc it's in e-stop mode, i was thinking of using the NO contacts of the e-stop drifve a 24vdc signall to one of the input pins. what do you think?
[01:22:34] <Connor> zeeshan: Why not just check to see if the 24v signal is gone?
[01:23:05] <zeeshan> correct me if im wrong
[01:23:17] <zeeshan> but since the input pins are sinking
[01:23:32] <zeeshan> that means they need a 24vdc signal to change state right?
[01:24:20] <Connor> +24v through the NC side of estop, to the coils of the contactors AND to a 24v INPUT on the 7i77 (in parallel).
[01:24:42] <Connor> When E-Stop is engaged, it cuts power to the contactor, and drops the power to the 7i77 pin.
[01:24:52] <Connor> thus, you see your signal state change.
[01:25:07] <Connor> in lcnc you can invert the signal if needed.
[01:25:07] <zeeshan> well i guess i need to clarify this confusion
[01:25:18] <zeeshan> it's a sinking input...
[01:26:07] <Connor> The difference is, 7i77 requires a positive voltage, the other requires it to be grounded.
[01:26:24] <Connor> since your E-Stop will have 24v+ running through it.. not a ground.. your good.
[01:27:12] <zeeshan> okay that makes sense :)
[01:27:26] <zeeshan> im providing postive 24vdc through a limit switch then to an input pin
[01:27:32] <zeeshan> so the e-stop isnt any different
[01:28:02] <Connor> and the reason is.. you can have false inputs if you were to ground out a wire by accident via chafed wire or something.
[01:28:33] <zeeshan> i totally agree
[01:28:35] <zeeshan> i was thinking of it wrong
[01:28:37] <Connor> Correct, no diff between the limit and estop setup.
[01:29:15] <zeeshan> im counting the 24vdc signal requirements
[01:29:16] <Connor> and them being setup in a NC state insures that if a wire breaks.. your estop will bill tripped, or limit will be tripped thus, making it "fail safe"
[01:29:37] <zeeshan> im counting 17 pins!
[01:29:41] <zeeshan> er
[01:29:45] <zeeshan> 17 +24vdc signals
[01:29:51] <zeeshan> going to need a buncha terminal blocks
[01:30:03] <zeeshan> im looking at the dn-qd12x-a on automation direct
[01:30:12] <zeeshan> in .2" of din rail space
[01:30:15] <zeeshan> it gives you 4 pins
[01:30:22] <zeeshan> i only have 2" of space to spare
[01:30:37] <zeeshan> plenty of space :)
[01:30:58] <Connor> Hmm.. that's a 2 tier setup.
[01:31:39] <zeeshan> the way im imagining it is
[01:31:51] <zeeshan> 24vdc supply -> din rail term block -> each limit switch, solenoid, sensor , etc
[01:32:10] <zeeshan> then the return wires from each switch for example will go to the associated input on 7i77
[01:32:20] <zeeshan> for a solenoid it'd be a bit different
[01:32:30] <zeeshan> it'd go back to the -24vdc rail
[01:32:42] <Connor> and from 7i77 output.
[01:32:47] <Connor> http://www.galco.com/buy/Wieland/57.403.7055.0
[01:32:52] <zeeshan> my solenoid for the hydraulic tool changer
[01:32:55] <Connor> I used those for my 48v buss
[01:32:58] <zeeshan> i've decided won't go to 7i77
[01:33:03] <zeeshan> there is too high chance of a accidental trip
[01:33:06] <zeeshan> im wiring it to a direct switch
[01:33:18] <Connor> ok
[01:33:20] <zeeshan> the 7i77 will be inline to monitor things like "is the spindle running"
[01:33:27] <zeeshan> with a relay latching that solenoid
[01:33:54] <zeeshan> have you tried the screwless term blocks?
[01:34:00] <zeeshan> ive only used screw.
[01:34:10] <Connor> No.
[01:34:47] <Connor> so, using the 7i77 as a interlock.
[01:34:51] <zeeshan> yes
[01:35:46] <zeeshan> +24vdc -> relay switch side controled by 7i77 -> momentary switch -> -24vdc
[01:36:05] <zeeshan> last thing i want is a tool flying out at 3000 rpm
[01:36:26] <Connor> I'm kinda stalled out right now.
[01:36:30] <zeeshan> why
[01:36:31] <Connor> can't do anything.
[01:37:05] <Connor> Well.. I need Pete's help to machine some stuff on the Base and saddles of the G0704, and finish making one of my ballnut mounts.
[01:37:27] <Connor> and.. I found out that my house has really bad white mold issue.. along with some plumping issues
[01:37:34] <pfred1> I was kinda stalled out today myself
[01:37:54] <Connor> Probably going to be after the first of the year before I can do anything.
[01:38:12] <zeeshan> don't stress
[01:38:19] <zeeshan> i took a break from this cnc stuff for a couple weeks
[01:38:22] <zeeshan> just getting back into it
[01:38:31] <pfred1> heck I've taken years off
[01:38:32] <zeeshan> its nice to have a break :)
[01:39:05] <Connor> CNC stuff is my stress reliever
[01:39:06] <pfred1> it would be nice to have my machine running again before Christmas but I donot know if that is going to happen, or not
[01:39:30] <zeeshan> connor can you dehumidy?
[01:39:33] <zeeshan> and kill the white mold like that?
[01:39:37] <pfred1> yeah if I'm not in the mood i don't mess with it
[01:39:46] <Connor> Going to have to take out a Home Equity Line of Credit to get the $$$ to help cover the cost of repairs.
[01:39:50] <zeeshan> pfred1: what kind of machine do you have
[01:39:55] <pfred1> I get green mold that gorw on the outside of my house
[01:40:15] <pfred1> well technically right now I guess I don't have anything at all but usually a router
[01:40:22] <Connor> zeeshan: It's going to take a professional cleaning company to remove it. Repair some major wood fungas and wood rotted floor joists..
[01:40:31] <zeeshan> =/
[01:40:36] <pfred1> I kill my mold with bleach and jomax house wash
[01:40:38] <Connor> and then we need to enclose the craw space and stuff to keep it from happening again.
[01:40:57] <zeeshan> i have some black mold in the washroom
[01:40:57] <Swapper> would it be even manageble to put linear rails on a RF45 style z column ?
[01:40:57] <pfred1> I'd have to move my house to prevent mold from growing on it
[01:41:00] <zeeshan> only place w/ mold
[01:41:01] <Connor> also need to have the duct work cleaned and flex duct replaced.
[01:41:03] <zeeshan> ftoo much humidity
[01:41:19] <pfred1> bah germcidal bleach kills the stuff
[01:41:24] <Connor> zeeshan: Yea.. I live in Tennessee..
[01:41:43] <zeeshan> this is why we need concrete block houses
[01:41:46] <zeeshan> :)
[01:41:48] <pfred1> you can watch the mold change colors as it dies its fun
[01:41:54] <zeeshan> pfred1: is it instant?
[01:42:02] <Connor> and keep the house around 67.. which causes the ducts to condensate..
[01:42:05] <pfred1> well it happens right before your eyes
[01:42:17] <pfred1> it don't take long
[01:42:23] <zeeshan> pfred1: i have like a 2" spot (circle) where the mold is confined on the wall
[01:42:30] <pfred1> I use one of them spray pump bottles to spray it
[01:42:30] <zeeshan> do you think it goes into the dry wall too
[01:42:31] <Connor> pfred1: Insurance should cover Mold removal, just not the damage.
[01:42:34] <zeeshan> or would it be only on the surface
[01:42:36] <zeeshan> so it can breathe
[01:43:33] <pfred1> I live in delaware and mold gorws on the outside of lots of houses here
[01:43:42] <pfred1> it seems to favor some colors more than others
[01:43:55] <pfred1> it likes the color my house is
[01:44:02] <Connor> Only GOOD thing that might come from this is ability for me to enlarge my workshop and maybe buy a 10x22 lathe...
[01:45:04] <pfred1> then once i kill it with bleach and house wash I pressure wash it off
[01:46:25] <pfred1> before it dies the stuff really clings
[01:46:40] <pfred1> but once its dead it washes off more easily
[01:47:37] <Connor> They're going to soda blast it out.. and then treat it with chemcials
[01:47:50] <pfred1> hmm i say treat first
[01:48:09] <pfred1> kill it in place
[01:48:23] <Connor> I say, let them do it. I'm not professional, and insurance is covering the removal.
[01:48:30] <pfred1> cool
[01:48:47] <pfred1> insurance doesn't pay me to wash my house I should see if they would
[01:48:50] <Connor> but, I have to foot the bill for deductible, and repair
[01:48:50] <zeeshan> is it ONLY on the surface??
[01:49:05] <Connor> zeeshan: In My case? Probably not.
[01:49:14] <Connor> some of it has damaged the floor joist.
[01:49:39] <pfred1> if it is just dry rot you can fix that
[01:49:58] <Connor> It's not.
[01:50:02] <pfred1> oh
[01:50:24] <Connor> Wood eating Fungus possibly.
[01:50:30] <Connor> I'll no more in the next few days.
[01:50:31] <pfred1> I've taken wood that was like a sponge and made it sound again with wood hardener
[01:50:37] <Connor> err.. I'll know more.
[01:50:57] <roycroft> insurance should not pay you to wash your house
[01:51:03] <roycroft> that's why you breed
[01:51:09] <pfred1> wood hardener is sort of like thinned out fiberglass resin it soakes into the wood and makes it really sturdy
[01:51:47] <zeeshan> hkm
[01:51:54] <zeeshan> apparently vinegar is an alternative to toxic bleach
[01:51:55] <zeeshan> :P
[01:52:10] <pfred1> bleach isn't toxic to me in small amounts
[01:52:18] <pfred1> it messes mold up though
[01:52:48] <pfred1> heck we treat city water with bleach and drink it
[01:52:58] <pfred1> chlorine is bleach
[01:52:58] <Connor> I'm hoping that fixing this helps with my wife's health issues.
[01:54:28] <Connor> time for bed. later guys
[01:54:32] <pfred1> somefolks are really allergic to mold
[01:55:54] <roycroft> i'm pretty sensitive to mold and mildew
[01:56:08] <roycroft> to most smells, actually
[01:56:19] <roycroft> i'm extremely sensitive to cigarette smoke
[01:56:53] <pfred1> some smells bother me
[01:57:33] <pfred1> we were roofing Hartx Mountain and they make hampster food there
[01:57:50] <pfred1> let me tell you the smell of roasting hampster food is nothing I care for
[01:58:27] <pfred1> guy running the machine was eating his lunch operating it though I guess folks get used to anything after a while
[01:59:02] <pfred1> we were getting bowled over by the stench out on the roof just because it was wafting out of a couple broken windows at us
[01:59:43] <pfred1> but in the middle of the day our extension cord came unplugged so we had to go back into that room to plug it back in
[01:59:52] <pfred1> only one guy made it
[02:00:09] <pfred1> when he came out he said he had dogs so he was used to pet food odors
[02:00:39] <pfred1> guy must have been living on dog food to have put up with that stink
[02:00:54] <pfred1> it was nasty!
[02:01:35] <pfred1> hampster food is green before they roast it then it turns brown
[02:06:09] <roycroft> soylent green is raw hampster food!
[02:06:42] <pfred1> yeah could be
[02:06:43] <Jymm> soylent green is people!!!
[02:07:14] <pfred1> there was this pivoting arm that dropped the pellets onto this other machine that looks like a burger roaster out of burger king
[02:07:47] <pfred1> then this ugly fat slob that just sat there and watched it all day long
[02:08:13] <pfred1> I didn't see him do anything other than eat his lunch he didn't evne get up to do that
[02:08:38] <ReadError> wood hardener is pretty cool
[02:08:44] <ReadError> the solvents they use are pretty strong
[02:14:19] <pfred1> yeah a carptender on a job turned me onto it and it works
[02:14:44] <pfred1> use the whole bottle when you open it though because it don't keep
[02:24:28] <Deejay> moin
[02:34:04] <Swapper> morning
[02:48:29] <Valen> I want to get swell lock for wood
[02:48:35] <Valen> gotta put an axe head onto a handle
[02:48:52] <Valen> bleach can be used to sterilise water in a pinch btw
[02:50:45] <roycroft> well, sanitize it
[02:51:01] <Valen> btw Connor anti mould paint actually works pretty well
[02:51:04] <roycroft> to sterilize it would require so much bleach it the water would be non-potable again
[02:51:41] <Valen> our bathroom used to get pretty festy, (on wallpaper with no ventilation), I painted it with some anti-mould bathroom paint, just a quicky and it hasn't come back
[02:52:26] <Valen> I'm wearing my mould killing shirt at the moment lol, its dark blue with bright purple dribbles on it where bleach dripped onto it from spraying it around the walls and roof
[03:18:18] <pfred1> I ruined a pair of sweat pants when I disinfected my garden pond
[03:18:25] <pfred1> I really went nuts with the bleach
[03:18:56] <pfred1> some lady gave me these water plants for it and attached was this other alge and that stuff took off
[03:19:22] <pfred1> so I drained the whole pond and hosed it down wiht bleach
[03:19:41] <pfred1> I had my doubts but that took that alge out
[03:19:44] <Valen> I need to do that to my fish tank
[03:19:51] <Valen> bleach is great stuff ;->
[03:20:04] <pfred1> I went nuts I wanted it to work
[03:20:11] <pfred1> I hated that alge
[03:20:26] <Valen> +1 for my fish tank ;->
[03:20:28] <pfred1> I spent a whole supper with a sieve trying to strain it out
[03:20:35] <pfred1> summer even
[03:20:41] <Valen> I killed off one type but the other survived
[03:21:14] <pfred1> I'd almost get all of it but a little bit would escape and then one warm day blammo it'd be all over the place again
[03:22:31] <pfred1> I've completely given up on water gardening that is a lot harder than it looks
[09:06:02] <mutley> afternoon
[09:06:25] <mutley> wondering if i can get some useful advice regardin machining plastics and the correct bits
[09:06:35] <mutley> essentially nylon
[09:06:53] <mutley> i get too much "melt" going on
[09:07:11] <mutley> using a kress spindle with a minimmum speed of 10k rpm
[09:07:32] <mutley> its been sggested i use a fast spiral cutter, carbide alumnium cutter possibly
[09:07:33] <skunkworks> go faster? coolant?
[09:07:44] <mutley> using coolant
[09:07:52] <skunkworks> *feed
[09:07:55] <mutley> faster as in feedspeed, or spdle speed?
[09:08:13] <mutley> wow realy
[09:09:19] <mutley> anyone have a good source of cutters in the uk
[09:09:48] <mutley> cutters/mill bits
[09:09:49] <PetefromTn_> what cutter are you using now?
[09:10:19] <mutley> twin flute standard helix angle around 30 degrees
[09:10:47] <PetefromTn_> you might try a single flute higher helix model and ramp up your feedrates
[09:10:51] <mutley> i spoke with an "old boy" type machnist, he suggested i need to lower spindle speed, and use a fast helix cutter
[09:11:05] <mutley> ie closer to 45 degree helix
[09:11:13] <PetefromTn_> I thought you were already going as slow as possible..
[09:11:28] <PetefromTn_> spindle speed that is
[09:11:39] <mutley> yea i been finding single flute not easy to obtain for some reason in the uk, maybe i look in the wrong places
[09:11:50] <mutley> PetefromTn_: yea as slow as my spindle will allow
[09:11:52] <PetefromTn_> try ebay
[09:12:05] <mutley> i am considering getting another spindle that will go lower
[09:12:07] <mutley> slower*
[09:12:09] <PetefromTn_> what are your feeds and speeds
[09:12:50] <PetefromTn_> basically if it is melting you are going too slow really and your spindle speed is too fast but you cannot lower it so you need to feed faster
[09:15:00] <mutley> mmmm
[09:15:20] <mutley> yea i may look at a slower spindle then aswell, any suggestin for such an item?
[09:15:30] <mutley> curently got a kress 1050 multi speed
[09:15:34] <mutley> 10-40k
[09:16:14] <mutley> my feedspeeds have ranged from150 -500
[09:16:19] <PetefromTn_> I assume this is a small table top router then?
[09:16:59] <mutley> well, its not one of those large industrial types, but its not quite table top
[09:17:22] <mutley> its a home brew, but made out of 40x80 and 40x120 extrusions, linear rails and ball screws
[09:17:27] <mutley> nema23 motors
[09:18:07] <mutley> and a proven control system that i darent mention (planet coughcoughcnc cough) that works well
[09:18:26] <mutley> its just this melt issue im trying to combat,
[09:19:39] <PetefromTn_> is that 500mm per minute or inches or what?
[09:19:50] <mutley> otherwise its a pretty stable solid machine
[09:19:54] <mutley> mmpm
[09:20:05] <PetefromTn_> yeah that is what like 20IPM?
[09:20:31] * mutley fumbles for a calculator
[09:20:38] <PetefromTn_> that is pretty slow really
[09:20:54] <PetefromTn_> what are your depths of cut and engagement?
[09:20:58] <PetefromTn_> slotting?
[09:21:11] <mutley> yea 20 inches per minnute
[09:21:13] <PetefromTn_> you just need to try to feed faster I think from what it sounds like
[09:21:30] <mutley> mmmm ok
[09:21:34] <PetefromTn_> either that or get a spindle that runs in the less than 10k range
[09:21:50] <mutley> i tend to take of 1mm at a time
[09:21:59] <mutley> the first few cuts are fine
[09:22:12] <mutley> its as i start to get deeper it then has problems
[09:22:31] <PetefromTn_> are you clearing chips well?
[09:22:38] <PetefromTn_> use some compressed air maybe
[09:22:48] <mutley> PetefromTn_: yea well i think possibly in a roundabout way your confirm some of what i was thinking and also what the old boy machnist was saying
[09:22:57] <mutley> yea i use air
[09:23:05] <PetefromTn_> but I would look into a quality single flute cutter and up that feedrate
[09:23:12] <mutley> ive even used a water spray aswell
[09:23:23] <PetefromTn_> water?
[09:23:39] <mutley> yea to try and help cool the tip
[09:23:46] <mutley> take some of the heat away,
[09:23:46] <PetefromTn_> you might try a mister with coolant if your machine is not all MDF or something.
[09:23:58] <mutley> yea its all metal
[09:24:01] <mutley> no wood
[09:24:34] <mutley> ok well i ight have to ammend my letter to santa then
[09:25:33] <PetefromTn_> you should check out a feed and speed calculator there are several free ones available
[09:26:29] <PetefromTn_> there is one called FZwizard that seems decent
[09:26:44] <PetefromTn_> or rather FS wizard
[09:27:49] <mutley> ok
[09:28:19] <PetefromTn_> full slot with guessing a quarter inch cutter you should be around 140 IPM at 10k rpm two flute it seems
[09:28:29] <mutley> in all honesty i think im part at fault for looking at doing some of this work half hearted/taking short cut
[09:28:33] <mutley> or not planning the work well enough
[09:28:44] <mutley> wow
[09:28:53] <mutley> almost sounds extreme to me
[09:29:13] <mutley> theres me going by the "gently does it" apprach
[09:29:14] <PetefromTn_> well watch some youtube videos of these smaller table top machines cutting plastics
[09:29:21] <mutley> rather than hell for leather
[09:29:50] <PetefromTn_> most of them are relatively not rigid so they cut shallow and fast
[09:31:11] <mutley> mmm interesting, makes sense
[09:31:14] <PetefromTn_> high speed and low speed will burn any cutter and you are heating up the material and cutter. Will burn it up and it will loose its edge quickly that way causing more burning and melting
[09:31:26] <PetefromTn_> low feed rather
[09:32:19] <PetefromTn_> but if there is a lot of backlash and play in the machine then all bets are off.....
[09:44:37] <mutley> enter the vicious crcle
[09:45:08] <mutley> my machine is pretty rigid and no backlash/very low
[09:58:46] <mutley> PetefromTn_: really appreciate your advice, many thanks, ill pop back and let you know how i gt along in a few days
[09:58:50] <mutley> skunkworks: you too :)
[09:59:04] <PetefromTn_> sure good luck man
[10:00:38] <mutley> cheers :)
[10:08:36] <archivist> nobody mentions effin sharp cutters too else rubbing causes heat rise
[10:11:17] <malcom2073> I've always heard that from my dad, for plastics you have to have a really sharp cutter
[10:13:10] <archivist> and then the part you are rubbing against start to expand and make the problem worse, dont ask me how I know :)
[10:16:45] <skunkworks> You should have sharp cutters cutting plastic
[10:21:22] <PetefromTn_> you should have sharp cutters cutting almost anything so it goes without saying I figured
[10:32:41] <roycroft> if you can't find a single flute cutter that you like you can take a two flute cutter and grind one of the flutes down a little bit
[10:32:51] <roycroft> a few thousandths is enough to turn it into a single flute cutter
[10:37:38] <skunkworks> it is harder or impossible to get a carbide as sharp as a hhs cutter
[10:37:43] <skunkworks> HSS
[10:47:30] <SpeedEvil> Won't careful diamond polishing get it as sharp?
[10:47:40] <SpeedEvil> Life when that sharp is another question of course
[10:50:31] <pcw_home> I suspect for plastic you want sharp and a narrow angle, something that carbide does not do well
[10:51:02] <pcw_home> (too brittle)
[10:53:05] <CaptHindsight> but polymers won't have the same force required as metals, so lower shock waves
[10:56:25] <pcw_home> sort of like a block plane, carbide is not a good choice
[10:58:01] <CaptHindsight> themosets and themoplastics will behave very differently during cutting
[10:58:28] <CaptHindsight> thermosets won't melt whereas themoplastics will melt
[11:01:56] <CaptHindsight> that another difference between cast vs extruded acrylic panels (somebody asked about it recently)
[11:02:27] <CaptHindsight> cast is thermoset, extruded is a themoplastic version
[11:15:47] <SpeedEvil> I've been wondering about thermoset resins since I saw how cheap fibreglass was
[11:15:52] <SpeedEvil> that is - the glass fibre
[11:16:05] <SpeedEvil> I can buy a 17kg roll for 35 pounds, shipped.
[11:16:26] <SpeedEvil> And pulltrusion seems like fun
[11:16:56] <SpeedEvil> 110 ton-meters per pound.
[11:25:25] <CaptHindsight> structural pultrusions are typically expoxy and fiberglass with clay
[11:25:47] <CaptHindsight> expoxy/epoxy
[11:28:51] <SpeedEvil> clay?
[11:29:06] <SpeedEvil> you mean the clay as an additional filer?
[11:29:10] <SpeedEvil> makes sense I guess
[11:32:54] <CaptHindsight> clay as a filler
[11:33:16] <CaptHindsight> same as body filler (Bondo)
[11:34:19] * SpeedEvil idly wonders if you can fire fibreglass+clay and get a functioning ceramic.
[11:34:20] <CaptHindsight> Bondo = unsaturated polyester + clay + talc, just add fiberglass to make a pultrusion
[11:34:21] <SpeedEvil> I suspect the answer is it's pointless and the fibres melt
[11:34:21] <SpeedEvil> (for normal e-glass anyway)
[11:34:57] <SpeedEvil> How doesn't it stick to the extruder?
[11:35:03] <SpeedEvil> Do you coat it with a PTFE or wax film or something?
[11:35:13] <CaptHindsight> thin with an active solvent, IBOA, TPGDA etc
[11:35:36] <SpeedEvil> you mean injected around the extruder?
[11:35:55] <SpeedEvil> Is there an 'idiots guide to pulltrusion' online anywhere?
[11:36:13] <CaptHindsight> the extruder is under pressure and you clean it out before it sets
[11:36:18] <SpeedEvil> Filliment winding seems very straightforward
[11:36:36] <SpeedEvil> CaptHindsight: I thought it basically set in the extruder at extremely elevated temperature
[11:36:40] <SpeedEvil> ah
[11:37:06] <CaptHindsight> I haven't seen one but I know they lease the pultrusion equipment. It might be patent encumbered
[11:37:21] <SpeedEvil> Doubtful
[11:37:29] <SpeedEvil> (any more anyway)
[11:37:29] <SpeedEvil> But good point
[11:38:09] <SpeedEvil> Gah
[11:38:14] <SpeedEvil> How did I fail to look at wikipedia
[11:39:33] <jdh> you didn't want to pay $3
[11:39:43] <jdh> and be reminded that you should pay $3 or wtf
[11:41:15] <SpeedEvil> I blame alcohol.
[11:41:22] <SpeedEvil> I'm not sure why, as I don't drink though.
[11:41:58] <CaptHindsight> drugs and alcohol have been used as scapegoats for decades
[12:43:15] <anonimasu> anyone have a clue what to do when you use bldc and you got abs(commutation angle) and also, incremental in the same time
[13:12:23] <Deejay> re
[14:10:24] <anonimasu> PCW: are you there?
[14:15:37] <PCW> Yeah but busy
[14:17:00] <anonimasu> I had a quick question what do I do with the absolute value for the 8i20 after
[14:17:16] <anonimasu> reading it from the encoder
[14:17:38] <anonimasu> to initialize the angle for commitation
[14:19:01] <anonimasu> PCW: I am a bit stuck on that part :)
[14:19:11] <anonimasu> everything else is hooked up(today)
[14:21:45] <PCW> The actual absolute angle you get from your encoders relative to what the 8I20 needs really needs to be determined by experiment
[14:23:19] <anonimasu> yeah, but what pin do i write it to
[14:24:07] <anonimasu> 8i20.0.0.angle?
[14:47:46] <anonimasu> or motor.
[14:47:57] <anonimasu> (I cant find a sample config of that :S
[14:54:25] <jdh> what is the biggest size bolt (.us) would you thread into the side of 0.25" 6061 plate?
[14:55:39] <zeeshan> usually the rule of thumb is
[14:56:00] <zeeshan> at least the diameter of the bolt of meat between the edge of the hole and the plate
[14:56:08] <zeeshan> because of the way the frustra distributes
[14:56:36] <zeeshan> http://www.roymech.co.uk/images/screw_17.gif
[14:57:42] <zeeshan> i meant to say 1/2 the bolt diameter
[14:58:50] <zeeshan> looks like 8-32 would work.
[15:05:47] <PCW> anonimasu: bldc.N.encoder-offset I believe
[15:07:48] <jdh> 8-32's are pretty much high on my list of 'taps-I-have-broken-off'
[15:08:09] <SpeedEvil> 6061? Why tap.
[15:08:29] <SpeedEvil> Sort-of-serious
[15:09:48] <jdh> vs?
[15:10:18] <SpeedEvil> drilling the appropriately sized hole, and then firmly screwing
[15:10:48] <SpeedEvil> Depends on the app of course
[15:12:43] <jdh> this is a mounting bracket for a camera.
[15:12:56] <jdh> the part being bolted to it will be slotted for height adjustment
[15:13:11] <SpeedEvil> probably not appropriate then - they can go in a little skew in some cases
[15:13:26] <SpeedEvil> It worked surprisingly well when I tried it though
[15:19:49] <PCW> Ha neon lights counting up on the Cinncinatti Millicron ACO module and WD fed
[15:19:51] <PCW> Now if I can figure out how to read the inputs...
[15:28:23] <tjb1> Does anyone know what happens to a wave sping when its compressed, does the OD get bigger?
[15:31:38] <_methods> hmm
[15:31:41] <_methods> good question
[15:33:51] <_methods> i dont' think so but i think it depends on the type of wavespring
[15:34:13] <tjb1> http://www.mcmaster.com/#9714k75/=uytbpt
[15:34:15] <_methods> usually they're made to fit in a cavity
[15:34:46] <tjb1> Looking at that guy, unfortunately I can't really find anything similar with a higher weight. One thing I did read talked about stacking these in the past to raise the working load though.
[15:35:05] <_methods> yeah i dont' think tthat the dia should change on that
[15:35:17] <_methods> some of the clipped wave springs might though
[15:35:29] <_methods> they sell stacked wave springs
[15:36:00] <_methods> i guess mcmaster calls them high load compression springs
[15:36:14] <tjb1> I'd like something close to those diameters or something around 1.8 ID and under 2.75 OD with around 100-120lbs
[15:36:14] <_methods> http://www.mcmaster.com/#wave-springs/=uytcg8
[15:36:42] <tjb1> I can't find the size I need in that style
[15:37:02] <_methods> yeah you might have to get them from somebody besides mcmaster
[15:42:22] <tjb1> Might have to just try stacking the McMaster ones, not finding much else
[15:45:08] <zeeshan> im thinking stacking them might reduce their springiness
[15:45:19] <zeeshan> if you have wave washer , flat washer , wave washer
[15:45:21] <zeeshan> you might be ok :P
[15:45:28] <zeeshan> but if you stack like 10 of those wave washers
[15:45:29] <tjb1> thats an idea
[15:45:34] <zeeshan> i'm not sure what would happen
[15:45:51] <tjb1> spot weld them together at matching peaks
[15:46:09] <zeeshan> welding a spring is not good usually!
[15:46:16] <zeeshan> spot for them to crack
[15:46:19] <zeeshan> im not sure what your application is :)
[15:46:41] <zeeshan> the only place i've seen those wave washers is in the reverse gear
[15:46:43] <zeeshan> of my transmission
[15:47:14] <zeeshan> do you have to use a wave washer?
[15:47:17] <zeeshan> can you use a belleville?
[15:47:28] <tjb1> I'd like 100-120lbs
[15:47:37] <tjb1> Haven't seen a belleville that low
[15:47:46] <tjb1> with ID greater than 1.75
[15:48:23] <zeeshan> what id
[15:48:59] <zeeshan> http://www.mcmaster.com/#belleville-disc-springs/=uytikc
[15:49:25] <tjb1> http://www.smalley.com/wave-spring/ssr-0212
[15:50:56] <tjb1> So the spring is at least possible
[15:56:46] <anonimasu> PCW: I dont have counts I have rotor angle
[15:57:32] <PCW> well you will need convert
[15:57:39] <PCW> to convert
[15:58:20] <anonimasu> this is the absolute encoders
[15:58:28] <anonimasu> (hiperface)
[15:58:43] <anonimasu> I thought you could just feed electrical angle into something
[15:59:13] <anonimasu> like to the 8i20's
[16:00:51] <PCW> You can but you woudl have to create that number from the original angle and mod encoder count
[16:01:21] <anonimasu> well encoder counut is always zero on start
[16:01:56] <anonimasu> count...(which is the only time I dont have position
[16:02:23] <anonimasu> the encoder feedback is always active when power is on
[16:07:40] <PCW> sure but BLDC needs an absolute angle (which you would have to synthesize in HAL with mod encoder count and your original absolute number)
[16:07:41] <PCW> or encoder count and the original offset which suggests thar using bldc.N.encoder-offset is easier
[16:08:17] <anonimasu> what about rotor-angle? for the bldc component
[16:09:39] <anonimasu> sorry it's a out
[16:12:35] <anonimasu> pcw: encoder offset would be =Abs_Angle*Counts/rev
[16:12:46] <anonimasu> where abs_angle is between 0-1
[16:13:08] <anonimasu> pretty much
[16:15:53] <anonimasu> and the offset
[16:16:09] <anonimasu> does that seem like how it's done or tell me if im off completely
[16:16:17] <anonimasu> bbl

[16:37:52] <zeeshan> those box connectors dont look too bad
[16:38:18] <zeeshan> i wish i could somehow take my psu apart
[16:38:21] <zeeshan> and remove all those extra wires
[16:38:25] <zeeshan> without resoldering
[16:38:30] <zeeshan> damn these nonmodular supplies
[16:41:23] <Connor> zeeshan: No, That doesn't look too bad.
[16:42:35] <Connor> 1 thing you could do to get more room.. would be turn the 7i77 on the edge.. or mount it to the wall on the right hand side
[16:43:49] <zeeshan> i agree
[16:43:58] <zeeshan> i honestly didnt account for space usage
[16:44:05] <zeeshan> i was just trying to make it the most easiest to access
[16:44:15] <zeeshan> modifying stuff on the lathe controller is a pain in the butt cause its all packed
[16:44:48] <zeeshan> the goal is to mount this cabinet stuff on the wall beside the mill
[16:45:07] <Deejay> gn8
[16:45:21] <zeeshan> connor think double sided tape is good enough for mounting a ssd drive? :)
[16:45:28] <zeeshan> i forgot to drill holes for it :-(
[16:45:55] <Connor> zeeshan: Yes. That's how mine is right now. :)
[16:46:04] <zeeshan> haha nice
[16:46:13] <zeeshan> are you using the 3m double sided tape?
[16:46:18] <Connor> I also had to repair the SATA connector on min..
[16:46:21] <Connor> Yea.
[16:46:51] <Connor> The plastic center broke on the SSD during my re-working of the enclosure.
[16:47:21] <zeeshan> doh
[16:47:33] <Connor> wife had some nail glue that you use with a brush.. I.E. Polyvinyl acetate I.E. super glue.
[16:47:59] <Connor> put some on the bottom edge of the plastic and held it in place and let it setup.. looks to be working good..
[16:48:15] <Connor> That PSU for the computer.. that ONLY for the computer?
[16:49:04] * JT-Shop just dragged home a 3/4" steel table... dunno where I'm going to put the damn thing
[16:49:15] <zeeshan> connor yes
[16:49:19] <zeeshan> and one case fan
[16:49:29] <zeeshan> i figure i should put a 12v fan on there
[16:49:32] <zeeshan> and make use of the power :)
[16:49:56] <Connor> How many watts do you need for the computer ?
[16:50:07] <Tom_L> JT-Shop how big is it?
[16:50:13] <zeeshan> connor no idea :)
[16:50:22] <Connor> might look at these..
http://www.logicsupply.com/components/power-supplies/picopsu/
[16:50:36] <Connor> you could remove that huge PSU and condense down to one of those.
[16:50:51] <zeeshan> i think the athlon xp 3200+
[16:50:55] <zeeshan> eats at least 200W :P
[16:50:59] <zeeshan> i'm not 100% sure
[16:51:13] <Connor> Oh. Then those won't work. 160W is the largest I think.
[16:51:14] <zeeshan> ive always done the "throw in a big supply there and hope it works method"
[16:51:30] <Connor> Graphics card is what eats up allot of the PSU
[16:51:36] <JT-Shop> 32" x 48"
[16:51:48] <Tom_L> nice
[16:51:54] <zeeshan> how much JT-Shop?
[16:52:00] <Tom_L> mine's about the same size but 1/2" plate
[16:52:15] <Tom_L> i wouldn't sell it for anything
[16:52:26] <zeeshan> i built mine
[16:52:28] <zeeshan> it was a pain in the ass :)
[16:52:37] <zeeshan> i had to build it upside down
[16:53:08] <_methods> i just use my tablesaw table lol
[16:53:15] <_methods> old tannewitz
[16:53:30] <JT-Shop> I think it is about 400
[16:54:02] <JT-Shop> I have a 48 x 48 x 1 table that came off a machine
[16:54:09] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/framewelded2.jpg
[16:54:40] <zeeshan> i dont remember how big it is
[16:54:45] <zeeshan> 5x3.5?
[16:55:13] <zeeshan> 1" holy cow
[16:55:16] <Connor> My workbench.
http://www.ivdc.com/cnc/shop/559.JPG
[16:55:17] <zeeshan> that prolly weighs 1300lb
[16:55:18] <zeeshan> :)
[16:55:23] <zeeshan> connor yours is the best
[16:55:27] <zeeshan> its stainless too!
[16:55:35] <renesis> athlon xp 3200+ was like 80w
[16:55:38] <renesis> had one of those
[16:55:42] <renesis> almost everyone did, heh
[16:55:48] <zeeshan> overclocking heaven
[16:55:59] <zeeshan> amd made some shit processors
[16:56:02] <renesis> was when intel had their head up their ass and no one gave a shit about power
[16:56:02] <zeeshan> they always ran so hot
[16:56:02] <JT-Shop> where is the bench?
[16:56:36] <Connor> Stainless elevator door.. + I-Beam construction.. Was a Bomb rack for Airforce for 500lbs bombs. :)
[16:57:11] <_methods> your table IS the bomb
[16:57:40] <Connor> http://www.ivdc.com/cnc/mill_02_26_14_02.JPG
[16:57:41] <_methods> holder
[16:58:00] <Connor> in that picture you can see in the lower portion of the screen the caster wheel and some of the I-beam structure.
[16:58:32] <Connor> next to the jug of coolant and the AC wire.
[17:09:03] <mrsun> happy to see its not only my bench that looks like that! =)
[17:15:24] <Connor> mrsun: That was several months ago. It got cleaned up a bit when i moved the mill onto the stand.. but, now, it's a bit messy again because the mill is torn apart.
[17:18:33] <mrsun> been there, done that =)
[17:24:54] * JT-Shop needs to quit dragging shit home... shop too full
[17:32:55] <Jymm> JT-Shop: Cargo containers are fairly cheao
[17:33:23] <Jymm> JT-Shop: and can be stacked!!!
[17:35:51] <JT-Shop> gotta have some flat ground and live in a sea port
[17:36:19] <JT-Shop> you don't see cargo containers in the woods of swamp east missouri
[17:36:25] <Jymm> Nope, they can be trasnported by truck anywhere
[17:36:52] <JT-Shop> yep you still need a place to put them
[17:36:59] <Jymm> You have a tractor, I'm sue you can MAKE flat land
[17:37:03] <Jymm> sure*
[17:37:11] <JT-Shop> I don't want to store things but have them where I can use them
[17:37:32] <Jymm> Then stop bringing more shit home =)
[17:37:44] <JT-Shop> and yea I can fire up the dozer and make it all flat I guess... the neighbors might complain if there place slides down the hill LOL
[17:37:59] <JT-Shop> their
[17:38:06] <Jymm> Underground container/bunker?
[17:38:21] <JT-Shop> your not supposed to know about that
[17:38:36] <Jymm> about what? ~grin~
[17:43:00] <Jymm> JT-Shop: where did you get your cannon powder from?
[17:45:19] <JT-Shop> Dixie Gun Works
[17:47:25] <Jymm> JT-Shop: I dont see powder
[17:50:03] <JT-Shop> they probably don't ship it
[17:50:29] <Jymm> I would think they would at least list it
[17:52:44] <andypugh> Oh my! Dixie Gun Works sells Gatling Guns. I rather suspect I wouldn’t be allowed one in the UK :-)
[17:59:23] <Jymm> andypugh: Make one, say it's a tool changer or automated dispensing system =)
[17:59:51] <andypugh> It certainly is the latter. It dispenses lead. Quickly.
[18:00:08] <Jymm> exactly =)
[18:00:32] <JT-Shop> I'm guessing a 6 lb cannon would be tough to explain over there as well
[18:01:15] <Jymm> Not a cannon, it's a rianwater collection and dispensing system
[18:01:58] <andypugh> Cannons are fine. You only need a shot-gun license for one.
[18:02:15] <Jymm> andypugh: how hard is that to get?
[18:02:49] <JT-Shop> one big shotgun
[18:05:36] <andypugh> I would need a gun cabinet, but that’s about it.
[18:12:55] <jdh> can you just make your own gatling?
[18:23:19] <Valen> I was just going to make a "fire supression system"
[18:23:28] <Valen> AKA water cannons
[18:31:01] <andypugh> jdh: Yes, I could make a Gatling gun, but then I would probably find myself in some sort of legal difficulty.
[18:32:59] <Rab> Or surrounded by 30,000 decomposing knights.
[18:34:17] <pfred1> I reas an article on the net someplace about this old guy with a machine shop under his porch and he makes working miniature replicas of gattling guns
[18:34:54] <pfred1> well working replicas
[18:35:12] <pfred1> I think they fired 22 longs?
[18:36:43] <andypugh> That’s not a toy.
[18:37:34] <pfred1> I don't know they seemed to be having fun playing with it to me
[18:38:38] <pfred1> check this guy out
https://www.youtube.com/watch?v=mAgDKR0L2RA
[18:39:03] <pfred1> his baby ma deuce
[18:39:21] <pfred1> that's cute!
[18:45:31] <pfred1> that's not a gun. Now that's a gun!
http://www.hightech-edge.com/wp-content/uploads/gau-8-a-30mm-gatlin-gun-vw-beetle-comparison.jpg
[18:46:05] <jdh> http://www.gatlingguns.net/pricelist.htm
[18:46:23] <pfred1> we put wings on the Gau and call it the A-10
[19:05:39] <pfred1> well, I finally finished up the additional bracing on the X axis of my machine a litle while ago now
[19:05:50] <pfred1> it seems really solid to me now
[19:06:19] <pfred1> there are two belts of steel that wrap all the way around the machine
[19:12:32] <andypugh> Steel? Tungsten would be better :-)
[19:12:57] <pfred1> it would be much harder to cut, and drill, and tap though
[19:14:25] <pfred1> we had a sinker at the machine shop I worked in
[19:14:39] <pfred1> for when we needed holes in tungsten
[19:14:41] <_methods> we had a floater today at mie
[19:14:48] <_methods> s/mie/mine
[19:15:00] <_methods> i had to flush 2 times
[19:19:11] <PetefromTn_> Hey guys.....Is it possible to switch from metric to english display in the tool table?
[19:22:09] <pfred1> imperial not english
[19:22:14] <SpeedEvil> 0.192 nanofurlongs
[19:22:17] <PetefromTn_> whatever
[19:22:33] <pfred1> you put english on cue balls
[19:31:05] <jdh> you have a metric tool table?
[19:31:44] <PetefromTn_> yup
[19:32:00] <pfred1> egads
[19:34:01] <andypugh> PetefromTn_: I am pretty sure that the tool table is always in machine-native units
[19:34:19] <pfred1> I'm so glad the metric system never caught on for wide use here
[19:34:35] <andypugh> Probably simplest to use excel to change it then switch the machine basis.
[19:35:01] <andypugh> Or leave it as it is for when you decide to switch to a rational system
[19:35:05] <PetefromTn_> when connor and I setup the machine we made it innately metric due to the metric ballscrews
[19:35:18] <jdh> bummer
[19:35:22] <PetefromTn_> I REALLY REALLY regret that decision now
[19:35:33] <jdh> I have metric ballscrews and real units
[19:35:35] <PetefromTn_> I dunno how hard it would be to change it back
[19:35:45] <pfred1> PetefromTn_ you're like an inferior foreigner now or something
[19:35:57] <PetefromTn_> I wish this was funny
[19:36:03] <andypugh> I am not sure how touch-off works in non-machine units
[19:36:04] <jdh> it is for everyone else.
[19:36:06] <PetefromTn_> I am trying to use the cutter compensation
[19:36:14] <pfred1> with your puny little metric system
[19:36:31] <PetefromTn_> and making adjustments is a PIA
[19:37:34] <jdh> all your speeds/etc in ini are mm?
[19:37:46] <PetefromTn_> no
[19:37:55] <PetefromTn_> somehow the display is all in imperial
[19:37:56] <andypugh> PetefromTn_: Two options, switch the machine, or learn metric where it matters.
[19:38:34] <pfred1> I know metric but just looking at a metric scale gives me a headache
[19:38:34] <andypugh> You can run imperial G-code and view imperial DRO on any machine
[19:38:41] <PetefromTn_> Boy lots of condescension here today.. I don't need to learn shit I already use metric quite a bit thank you. I just want to make the tool editor table imperial
[19:39:11] <PetefromTn_> if that means I have to redo the whole machine then so be it
[19:39:14] <pfred1> all of those little millimeter hash marks ugh how does anyone tolerate it?
[19:39:23] <PetefromTn_> but I did not know how it worked so I came her for help
[19:39:28] <andypugh> PetefromTn_: Not condescending, I mix units a lot. I make Imperial parts on a metric machine all the time
[19:39:54] <PetefromTn_> I am USED to running commercial machines here and they are all imperial unless you WANT them to be metric
[19:39:55] <jdh> where are units specified other than [TRAJ] ?
[19:40:00] <andypugh> But I live in a metric world
[19:40:01] <PetefromTn_> this is ideally what I want from my machines
[19:40:32] <pfred1> andypugh in theory so do we the USA officially adopted the metric system in 1969
[19:40:51] <PetefromTn_> I don't really live in a metric world here and I want to do what I know best to minimize mistakes.
[19:40:52] <jdh> mine work fine in mm and inch
[19:41:09] <jdh> but, my tool table (such as it is) is imperial
[19:41:14] <pfred1> PetefromTn_ you do you just don't know it
[19:41:41] <PetefromTn_> ..
[19:41:57] <andypugh> And in 1812, but one of our Privateers stole your Meter. If you hadn’t declared war on us in 1812 we wouldn’t have stolen it, and you would be metric.
[19:42:07] <pfred1> andypugh in the mid 70s the USA even switched all of our gasoline pumps to liters
[19:42:25] <jdh> no we didn't
[19:42:31] <pfred1> andypugh within a week revolution was fermenting so we switched them all back
[19:42:33] <pfred1> yes we did
[19:42:44] <pfred1> in 1975
[19:42:58] <pfred1> it lasted about a week
[19:43:03] <PetefromTn_> boy this is so helpful
[19:43:14] <pfred1> people were flipping out buying gasoline by the liter
[19:43:47] <andypugh> PetefromTn_: It is not an enormous amount of work to switch your machine
[19:43:59] <PetefromTn_> okay how would one go about it?
[19:44:14] <jdh> if his speeds/etc are already in inches, what is there to change?
[19:44:17] <LeelooMinai> Shrink it by 2.54 factor:)
[19:44:30] <andypugh> PetefromTn_: Copy the entire config directory to something like “CInci_antiquated_units”
[19:45:16] <andypugh> Then go through the INI dividing by 25.4 eveywhere
[19:45:28] <LeelooMinai> Or better delete it, so you don't have second thoughts
[19:45:30] <andypugh> (it won’t be that many different numbers0
[19:46:27] <andypugh> No, keep the good, working config. Then you have the choice, and can have a metric-native any time you choose.
[19:46:48] <PetefromTn_> how do you switch configs back and forth?
[19:47:03] <andypugh> From the config-picker
[19:47:39] <andypugh> My machine can be a mill, a lathe, or an imperial lathe, depending on what config I choose
[19:47:51] <PetefromTn_> not familiar with the config-picker
[19:48:07] <andypugh> (and it is easy enough to have separate icons/shortcuts for each config
[19:49:09] <andypugh> If you go to the CNC menu and choose LinuxCNC, or type “linuxcnc” at the command lind you get the config picker
[19:49:21] <PetefromTn_> okay
[19:49:32] <PetefromTn_> right now we have the machine setup to load directly into linuxCNC
[19:49:49] <andypugh> You only don’t get the picker if you have a dedicated icon/shorcut
[19:51:50] <PetefromTn_> yes we have a dedicated icon and like I said it loads upon startup.
[19:52:13] <jdh> the last thing I made I drew in mm, which was ok, I just had to verify things since they didn't seem known.
[19:52:30] <andypugh> So, keep the metric one. It might be useful. Then edit the clone, it’s just simple maths. Excel (or equivalent) is probbaly the tool of choice for editing the tool-table. “Paste Special” with 25.4 on the clip-board and “divide” as the operation will do it in one shot
[19:52:35] <jdh> then the CAM made it in inches and it became more confusing.
[19:52:46] <Computer_Barf> ok so I pulled the trigger on the g0704 conversion kit
[19:52:57] <jdh> barf: which one?
[19:54:14] <Computer_Barf> http://s1294.photobucket.com/user/arizonavideo/library/Grizzly%20G0704%20CNC%20Kit%20RM-16%20C7?sort=3&page=1
[19:54:24] <Computer_Barf> this but c7 ballscrews
[19:54:26] <andypugh> PetefromTn_: Then you can try the new config from the CNC menu, and only when you are happy it works, change the shortcut/icon
[19:54:39] <PetefromTn_> okay..
[19:55:03] <Computer_Barf> anyone have any ideas on what cam software I should use?
[19:55:08] <PetefromTn_> so stupid question is 25.4 enough decimal places or is there more to ensure the screw pitch is correct?
[19:55:35] <jdh> it is exact
[19:55:47] <PetefromTn_> okay thank you.
[19:56:03] <andypugh> PetefromTn_: But: You can make imperial parts on a metric-native machine, it’s not _that_ hard. The only reason to switch is if you make 10x as many imperial parts as metric
[19:56:38] <andypugh> The inch was actually re-defined to the metric standard
[19:56:39] <jdh> and the tool table
[19:56:50] <PetefromTn_> yeah I know all this, I just hate having to convert my dimensions every time I need to adjust cutter positions in the table.
[19:57:56] <PetefromTn_> almost all of the parts and cutters I make are imperial and even when they are not MOST of the dimensions I get are... It just would be MUCH simpler for me and honestly this is how every machine in the shops I worked in are setup.
[19:58:01] <jdh> barf: looks nice. Can you get it with double-nuts?
[19:58:19] <andypugh> No real help for you, but the numerical entry boxes on all my machines allow me to type mm
[19:59:04] <andypugh> or in or tpi or pitch to auto convert unuts
[19:59:04] <PetefromTn_> I tried to do the auto math input on the tool table and it either did not work or I did it wrong.
[19:59:32] <PetefromTn_> I do enjoy using it to find the center of my parts at touch off tho.
[19:59:52] <PetefromTn_> nice feature and keeps me from having to reach for the calculator all the time.
[20:00:00] <Computer_Barf> jdh: idk , I would have to ask. it it just a matter of adding a second set of nuts?
[20:00:19] <jdh> dunno, connor got double nuts for his.
[20:00:24] <PetefromTn_> andypugh Do you use cutter compensation on your machines?
[20:01:10] <jdh> you using it for cutter wear, or for toolpaths?
[20:01:18] <andypugh> Sometimes. I typically only use it on hand-coded profiles. Otherwise I let the CAM do it
[20:01:20] <jdh> vs. letting your CAM do it for you
[20:01:22] <PetefromTn_> trying to yeah
[20:01:39] <PetefromTn_> I have been letting the CAM do it
[20:01:49] <PetefromTn_> but that is really a big disadvantage
[20:02:08] <PetefromTn_> not being able to change the offset without reposting is very time consuming
[20:02:23] <andypugh> I don’t do much generic milling. And I rarely care enough to be bothered about cutter wear
[20:02:42] <PetefromTn_> how do you creep up on a tight dimension?
[20:02:47] <andypugh> I really am not a good example to look at ;-)
[20:03:16] <andypugh> I don’t think I have ever milled a tight dimension.
[20:03:21] <jdh> barf: does he have prices somewhere?
[20:03:47] <ds3> use the cutter comp stuff if it is implemented
[20:04:02] <pfred1> my digital calipers taught me that 0.02mm = 0.001 inch
[20:04:03] <PetefromTn_> really? Well I have to often creep up on tight tolerance dimensions to get the parts right and having to repost after making a simple change is really sucking for me...
[20:04:09] <andypugh> I bore holes, rather than circular mill. Typically I am milling a shape
[20:04:10] <Computer_Barf> look up g0704 kit on youtube, i had to email him
[20:05:12] <jdh> way too much work.
[20:05:20] <jdh> belt drive looks interesting though
[20:05:30] <andypugh> PetefromTn_: Yeah, we play different games. The things I do would be stupid for you.
[20:05:47] <PetefromTn_> why do you say that?
[20:06:17] <PetefromTn_> you do make parts with your machines just like I do... perhaps you just make things that do not need to be very precise in certain areas is all..
[20:06:38] <PetefromTn_> it is much more than that really tho
[20:07:45] <PetefromTn_> to be able to overcome incorrect programming issues without having to repost code is also a nice feature... mostly it is just to make quick changes and adjust for cutter diameter to get the part to spec.
[20:14:18] <Computer_Barf> :( no cam recommendations?
[20:14:51] <andypugh> PetefromTn_: Most of the things I make are replicas of old castings. So none of the “shape” features are that critical. Hole positions and diameters often matter, but those are drilled/bored. I mainly work on old stuff where the 3D shape was only vaguely defined, and the engineering was all in the holes.
[20:15:38] <andypugh> Computer_Barf: Did you even ask a question?
[20:16:49] <Computer_Barf> yeah, I recently pulled the trigger on a kit for a g0704, I plan on running linux cnc but am not sure what to use as a cam
[20:17:16] <jdh> I mostly use cut2d since it is cheap and easy
[20:17:24] <jdh> could try cambam
[20:17:30] <Computer_Barf> most of the cams i see people recommend are for windows and I don't want to be switching back and forth
[20:18:01] <pfred1> we all like 'em cheap, and easy, don't we?
[20:18:33] <PetefromTn_> andypugh I trust I did not offend with my statements that was not the intention whatsoever. I am just used to doing things the way these shops locally all seem to do and I want to try to setup my machine in this manner and start using cutter comp as they do.
[20:18:45] <Computer_Barf> depends..
[20:19:09] <jdh> Pete: it is how you should have set up the machine in the first place.
[20:19:11] <Computer_Barf> but if more expensive means windows.. i would rather avoid, or have that be the second option
[20:19:14] <andypugh> PetefromTn_: No, in your situation that seems entirely reasonable.
[20:19:40] <PetefromTn_> from what little I have seen of that recent posts by methods on the autocad company's new release that is what I would be looking into for CAM
[20:19:58] <PetefromTn_> jdh I thought we already established that but thanks..
[20:20:13] <pfred1> I think some ancient versions of autocad run in wine
[20:20:22] <andypugh> PetefromTn_: It’s an hour or so of work to make an imperial config, and you always have the old one to fall back on. Just try it.
[20:20:30] <PetefromTn_> I am talking about their 3d cloud based setup.
[20:20:43] <andypugh> Fusion360?
[20:20:49] <PetefromTn_> andypugh Yes this is what I think needs to happen
[20:20:56] <PetefromTn_> yeah thats the one I think.
[20:21:20] <PetefromTn_> it looked quite impressive for what it is and as I recall there is a real cheap or free option for hobbyists.
[20:21:37] <PetefromTn_> forgive me guys tonight.
[20:21:48] <andypugh> Computer_Barf: PyCAM fits your requirements, but some of the 3D routines are unusably slow.
[20:21:49] <PetefromTn_> I was in the hospital two days ago
[20:22:01] <pfred1> has anyone here tried this?
http://pycam.sourceforge.net/
[20:22:11] <andypugh> pfred1: Yes
[20:22:19] <pfred1> andypugh well?
[20:22:26] <pfred1> is it worth the time?
[20:22:30] <andypugh> I just said :-)
[20:22:44] <pfred1> is it any good?
[20:23:13] <andypugh> It’s OK, but some of the 3D routines are unusubly skow
[20:23:31] <andypugh> (I typed it better the first time)
[20:23:54] <pfred1> yeah it does not seem to be too actively developed
[20:25:13] <PetefromTn_> if you can get that fusion 360 for cheap or free you really need to look at some youtube videos about it. That is a pretty powerful package...
[20:25:16] <FinboySlick> I think it'd be great if there was something other than OpenCASCADE (as in more modern and lighter) to write CAD apps in the open source world.
[20:26:04] <FinboySlick> PetefromTn_: I think they use HSMWorks for their CAM engine, which I think is excellent.
[20:26:26] <PetefromTn_> I just briefly watched some youtube videos and was quite impressed...
[20:26:55] <PetefromTn_> integrated CAD CAM with some good functionality and lots of toolpath options what more could you want.
[20:26:58] <PetefromTn_> 3d too
[20:27:15] <Computer_Barf> fusion 360 seems to be cloud based
[20:27:19] <PetefromTn_> I have not played with it but watched a bunch of videos one night about it
[20:27:45] <PetefromTn_> yeah it is cloud based as far as I understand.
[20:27:47] <andypugh> PyCAM can fail to produce a 3D path overnight that Mescam or CamBam can make in seconds.
[20:28:03] <PetefromTn_> jeez
[20:28:17] <Computer_Barf> yeah that sounds, like not what i want.
[20:28:18] <pfred1> ban!
[20:28:24] <pfred1> bam even
[20:28:24] <FinboySlick> PetefromTn_: The maths behind toolpath generation aren't trivial.
[20:28:30] <andypugh> Currenly I am using my 30 trials of CamBam. It isn’s as good as Meshcam, but it’s cheaper.
[20:28:40] <PetefromTn_> I can vouch for CAMBAM too... it is quite usable and capable
[20:28:57] <PetefromTn_> it does not really have a lot of stuff built in but you can CONFIGURE lots of neat stuff
[20:29:02] <Computer_Barf> cambam linux?
[20:29:06] <PetefromTn_> and there are plugins that help.
[20:29:11] <andypugh> Sadly not
[20:29:18] <PetefromTn_> what DO you want?
[20:29:31] <Computer_Barf> linux based cam
[20:29:32] <Computer_Barf> lol
[20:29:45] <pfred1> yeah I do not run Windows at all
[20:29:52] <PetefromTn_> FinboySlick To be sure... and the more complex the toolpath the more complex the program needs to be to support it.
[20:29:59] <andypugh> SheetCAM has a Linux version, and for 2.5D stuff it is fine, but is mainly aimed at plasma/laser/2D
[20:30:07] <pfred1> I have not run WIndows since about 1996
[20:30:30] <PetefromTn_> well I hate to tell you but almost all of the top CAM programs run under windoze.
[20:30:48] <pfred1> PetefromTn_ you're not telling me anything that I do not already know
[20:30:58] <PetefromTn_> wasn't trying to
[20:31:24] <andypugh> I run CamBam in a VM (On my Mac) and live with it.
[20:31:39] <PetefromTn_> but I have direct knowledge of Mastercam, CamBAM and Sheetcam as well as tried a few others so that is what I can speak of.
[20:32:17] <andypugh> PyCAM runs native, but it’s too slow at the moment. It could probably be fixed.
[20:32:49] <andypugh> But maybe it isn’t my job to fix it.
[20:33:11] <_methods> heekscad was alright for simple toolpaths
[20:33:24] <_methods> heekscam i mean
[20:33:57] <andypugh> Has anyone looked to see where the CAM module for FreeCAD is now?
[20:34:13] <_methods> wasn't that heekscam?
[20:34:14] <PetefromTn_> last I looked it was a ways off..
[20:34:32] <pfred1> a ways off like support for Imperial units?
[20:34:54] <andypugh> Yeah, no updates for years:
http://www.freecadweb.org/wiki/index.php?title=CAM_project
[20:34:55] <PetefromTn_> actually they sorta fixed that in FreeCAd
[20:34:57] <_methods> fusion360 is free and the toolpath gen was pretty damn good from what i saw
[20:35:11] <PetefromTn_> but the CAM is a ways off
[20:35:44] <PetefromTn_> there is a good bit of work going on in the forum about it last I checked. There are several posts that looked interesting.
[20:36:08] <PetefromTn_> _methods I agree I looked it after you spoke about it awhile back
[20:36:12] <PetefromTn_> looks very capable
[20:36:28] <pfred1> the state of Linux CAM is slim to none
[20:36:35] <PetefromTn_> have not tried to download it yet
[20:36:38] <PetefromTn_> need to
[20:36:52] <_methods> no lathe toolpathing though from what i saw
[20:37:03] * pfred1 will give dxf2gcode a shot
[20:37:06] <PetefromTn_> oh really...that sucks.
[20:37:43] <_methods> well it's hard to beat the pricing on it lol
[20:37:46] <PetefromTn_> I machined a couple parts for a local customer tonight. Kinda simple stuff that is getting bead blasted.
[20:37:48] <pfred1> isn't thre a g code generator plug in for blender?
[20:37:50] <_methods> and you can use it o linux
[20:38:05] <PetefromTn_> oh yeah it works on linux?
[20:38:20] <_methods> it's cloud based
[20:38:26] <PetefromTn_> yeah I know
[20:38:26] <_methods> so you can use it on whatever
[20:38:59] <PetefromTn_> it looked quite powerful from the youtube videos I watched. Some impressive features
[20:39:11] <andypugh> Night all
[20:39:14] <_methods> oh damn i'm a liar
[20:39:16] <Connor> Computer_Barf I would not use those couplers pictured in that kit. I would use Oldhams.
[20:39:16] <PetefromTn_> GN8
[20:39:21] <_methods> its only osx and windows
[20:39:40] <_methods> who the hell makes anything for osx
[20:39:49] <PetefromTn_> _methods Wanna hear about my week thus far?
[20:40:01] <_methods> shoot man
[20:40:18] <Connor> PetefromTn_: Wanna compare ? :)
[20:40:20] <PetefromTn_> Well Saturday morning I wake up and my wife makes me a nice breakfast
[20:40:33] <PetefromTn_> next thing I know I get a slight headache
[20:40:34] <Computer_Barf> Connor: theoretically i could pick those up later?
[20:40:45] <_methods> well that sounds like a good way to start
[20:40:58] <PetefromTn_> then all of a sudden my head starts spinning like fucking crazy
[20:41:10] <_methods> oh man
[20:41:12] <PetefromTn_> and I have to get on the floor.
[20:41:12] <Tom_L> did she drug you?
[20:41:27] <Connor> Computer_Barf: Yes. Does his kit come with the ballnuts & screws or you get those separate ?
[20:41:28] <PetefromTn_> HORRIBLY DIZZY AND EXTREMELY NAUSEOUS
[20:41:29] <Computer_Barf> Connor: btw ,what cam are you using?
[20:41:39] <Connor> Computer_Barf: I use CamBam
[20:41:47] <_methods> man that happened to me one time i had to go to the hospital
[20:41:54] <_methods> i had a potassium deficiency
[20:42:00] <PetefromTn_> spend the next three days in bed barely able to move my head at all
[20:42:03] <_methods> started havig seizures
[20:42:10] <PetefromTn_> finally had to go to the ER
[20:42:17] <Connor> PetefromTn_: That sucks.
[20:42:30] <PetefromTn_> they said I was terribly dehydrated and did a CT scan of my head
[20:42:34] <Computer_Barf> Connor: those pics are the rotons but I specified the c7 ballscrews for my kit
[20:42:39] <PetefromTn_> luckily they found no problems
[20:42:43] <_methods> wow
[20:42:48] <PetefromTn_> so they chalked it up to vertigo
[20:42:50] <_methods> scary as hell
[20:42:52] <Connor> Computer_Barf: No. The ones in this link are the C7
[20:42:56] <PetefromTn_> SCARED THE SHIT OUT OF ME..
[20:43:04] <PetefromTn_> I thought I was having a stroke or something.
[20:43:05] <_methods> yeah i was freaking out when i had my potassium thing
[20:43:09] <Connor> But.. you might see about getting double nuts with them..
[20:43:14] <_methods> they had to put me in a wheelchair
[20:43:18] <PetefromTn_> I have never been in that kind of mind scramble before.
[20:43:31] <PetefromTn_> yeah me too they wheeled me into the ER and everything.
[20:43:31] <Connor> PetefromTn_: Any sort of ear issues ?
[20:43:37] <Computer_Barf> ahh well either way c7's is what was selected for my order
[20:43:39] <_methods> horrible feelig
[20:43:50] <PetefromTn_> I would not wish this on my worst freakin' enemy..
[20:43:54] <_methods> i'm glad you're fine though
[20:44:00] <_methods> +1
[20:44:01] <_methods> hehe
[20:44:04] <PetefromTn_> just today I started to feel good enough to do anything.
[20:44:10] <Computer_Barf> the double ball nuts, theoretically I could pick up an additional 2 ballnuts and add them?
[20:44:25] <PetefromTn_> my head is still all messed up and I cannot turn my head too quickly or it feels like it will come back again.
[20:44:45] <PetefromTn_> they gave me what is basically turbo dramamine...
[20:45:18] * SpeedEvil thinks of the vladyvostok manoever
[20:45:37] <PetefromTn_> DAMN if that was not the worst feeling I have ever experienced in my life...
[20:45:48] <PetefromTn_> my eyes were spinning uncontrollably
[20:46:04] <PetefromTn_> I could not focus on anything for more than a moment for four days..
[20:46:18] <Connor> Wonder if one of the cilia in your ear broke off.
[20:46:31] <SpeedEvil> https://en.wikipedia.org/wiki/Epley_maneuver
[20:46:33] <SpeedEvil> err - no - that
[20:46:47] <PetefromTn_> they seem to think I got some kinda flu coupled with the dehydration and stress and the vertigo all rolled into one.
[20:46:53] <SpeedEvil> The Epley maneuver or repositioning maneuver is a maneuver used to treat benign paroxysmal positional vertigo (BPPV)[1] of the posterior or anterior canals.[2] It works by allowing free floating particles from the affected semicircular canal to be relocated, using gravity, back into the utricle, where they can no longer stimulate the cupula, therefore relieving the patient of bothersome vertigo
[20:46:58] <SpeedEvil> or that
[20:47:04] <PetefromTn_> thanks man I am familiar with that maneuver.
[20:47:11] <PetefromTn_> my wife has inner ear problems occasionally
[20:47:23] <PetefromTn_> I used to think it sucked for her when it happened
[20:47:27] <Computer_Barf> Connor: the double ball nuts, theoretically I could pick up an additional 2 ballnuts and add them?
[20:47:35] <PetefromTn_> now I have a HUGE respect and pity for her
[20:47:54] <PetefromTn_> because if it is ANYTHING like what I felt it sucks more than you can imagine sucking could suck...
[20:48:10] <Connor> The ones I have are a "set" for each ballscrew. They came pre-loaded with the ballscrews.
[20:48:53] <Connor> http://www.ivdc.com/cnc/ballscrews_100214_01.jpg
[20:49:01] <PetefromTn_> maybe I need to eat more potassium..LOL
[20:49:19] <pfred1> bananas
[20:49:28] <PetefromTn_> yeah his ballscrews with the preloaded nuts are really nice actually I saw them myself here.
[20:49:41] <PetefromTn_> yup bananas
[20:49:59] <pfred1> PetefromTn_ in any other channel your comment would be considered rather risque
[20:50:10] <PetefromTn_> which comment
[20:50:17] <pfred1> 21:22 < PetefromTn_> yeah his ballscrews with the preloaded nuts are really nice actually I saw them myself here.
[20:50:20] <Connor> rofl
[20:50:21] <PetefromTn_> aah
[20:50:30] <PetefromTn_> yeah well it is accurate so whatever
[20:50:52] <PetefromTn_> Connor and I have a SPECIAL relationship...heheh
[20:50:53] <FinboySlick> Yay for bananas:
https://www.youtube.com/watch?v=wCkerYMffMo
[20:50:59] <Connor> I'm freaking out a bit.. Still not sure what the deal is with the House. The mold and damage to the floor joist etc..
[20:51:17] <PetefromTn_> what damage?
[20:51:19] <Computer_Barf> have a flood?
[20:51:22] <pfred1> mold can be a serious issue
[20:51:41] <pfred1> I've heard tale told of houses having to be gutted over it
[20:52:09] <Connor> No Flood. We thought it might be a issue with the Sink drain and we thought we had issue with the toilet too... both the bathroom and kitchen floors are a bit soft.. the kitchen started getting REALLY bad a week or so ago.
[20:52:12] <PetefromTn_> there are HUNDREDS of houses in Florida and other parts that used that Chinese drywall that had to be gutted...
[20:52:26] <Computer_Barf> I used to work in mold remediation
[20:52:29] <pfred1> that was sulfer
[20:52:42] <pfred1> the chinese sheetrock
[20:52:44] <PetefromTn_> yessir
[20:52:47] <Computer_Barf> we did a ton of that when katrina happened
[20:52:55] <pfred1> houses smelled like rotten eggs I imagine
[20:53:03] <Computer_Barf> horrible stuff
[20:53:06] <Connor> but, one of the people looking it over today said we had some issue with the way the sunroom was done and it might be causing issues with the crawl space.
[20:53:07] <pfred1> or you had an old bulldog for a pet one of the two
[20:53:12] <PetefromTn_> it made a lot of folks sick and tore up metal parts in the house.
[20:53:18] <Computer_Barf> didn't breath right since then
[20:53:42] <pfred1> I really do try to avoid things madei n china anymore
[20:53:42] <Computer_Barf> all sensitive to anything after having done that work
[20:54:01] <Connor> have mold in the duct work too.. stupid heat and air guys told me I could leave the fan running all the time to help even the temperature in the house out.
[20:54:03] * FinboySlick has the sinking sensation that he just misplaced $40k.
[20:54:28] <Connor> that's a bad deal to do in the summer.. doesn't give the air time to condensate and drain off on the A coils.
[20:55:00] <pfred1> too bad they don't make a mold bomb like bug bombs
[20:55:25] <Connor> House on a 15 year mortgage with 6 years left.. and we going to have to take a freaking home equality loan out.
[20:55:43] <PetefromTn_> damn that sucks
[20:55:44] <Connor> pfred1: That wouldn't help in our case.. we have damage..
[20:55:45] <Computer_Barf> when houses get flooded , the gravity drags the water downward
[20:55:52] <PetefromTn_> is there anything you can do yourself?
[20:56:15] <Connor> PetefromTn_: No. You need full containment to clean it up.
[20:56:21] <Computer_Barf> so the top of the walls have certain levels of moisture, more further down. The walls will literally stripe with diffrent moulds
[20:56:22] <Connor> remove the old insulation.. etc etc.
[20:56:34] <Computer_Barf> green , black , brown
[20:56:51] <Connor> Computer_Barf: It's mostly white
[20:56:54] <Connor> in my case.
[20:57:12] <Connor> but, they're telling me the color doesn't matter... that can greatly depend on what the mold "Eats"
[20:57:14] <pfred1> Connor it may be time to call your friendly neighborhood arsonist
[20:57:27] <PetefromTn_> might have something to do with your wife's health issues...
[20:57:46] <Computer_Barf> basically, the diffrent ones compete , which is why mould is toxic. Its not so much the spores, but the substances created in association, to fight for territory against other types.
[20:57:50] <Connor> PetefromTn_: Yes Sir. It could be a contributing factor or a continues trigger.
[20:58:16] <pfred1> compete to be king of the mold?
[20:58:27] <pfred1> there can be only one!
[20:58:30] <Computer_Barf> lol
[20:58:35] <Connor> pfred1: And no.. I don't think I would do that.. I've had house fires as a Kid. I don't want to go through that again.
[20:58:38] <PetefromTn_> it's funny as I understand it.. everyone wants their houses to be nice and weather tight...
[20:58:53] <pfred1> Connor that's ehy you tell them to stop by when you're on vacation
[20:58:59] <PetefromTn_> but when your house is really weathertight you can get mold and other issues much easier
[20:59:09] <Connor> pfred1: No. not the fire itself.. the clean up and aftermath.
[21:00:02] <pfred1> I've thought about it and i know they check for accelerant so Ifigured just pack the crawlspace with crumpled newspapers
[21:00:14] <Connor> PetefromTn_: From my understanding. 2 design methods.. Open Crawl space.. and closed crawlspace.. Open is normally okay.. but, if you don't have enough ventilation under the house.. it can cause issues. When house was built.. no insulation.. no AC etc.. so it was good..
[21:00:37] <pfred1> they say now you're better off to leave yoru crawlspace vents closed
[21:00:37] <Connor> Closed Crawl space, if not done exactly right.. can create a perfect breading ground for mold...
[21:00:39] <PetefromTn_> Well I gotta machine the other sides of these parts tonight so I can get them ready for delivery tomorrow.
[21:00:47] <PetefromTn_> I am sure...
[21:01:03] <PetefromTn_> our crawlspace is open with vents all around that have screens on them.
[21:01:16] <PetefromTn_> but you can still get mold in there if not careful...
[21:01:28] <pfred1> we have vents that open and close I just leave them closed
[21:01:33] <Connor> pfred1: Yes.. but.it has to be done correctly.. ANY moisture under the crawlspace in a closed crawlspace and POOF you have major issues
[21:01:45] <Computer_Barf> Connor: so i guess if this guy only has single ballnuts, i would need to purchase doubles
[21:01:54] <PetefromTn_> hopefully I will be clear headed enough to drive tomorrow...
[21:02:10] <Connor> Computer_Barf: You can get them from linear motion bearings guy.. which is where he's going to get them too most likely.
[21:02:11] <PetefromTn_> not been able to drive or hardly walk for almost a week now.
[21:02:33] <pfred1> PetefromTn_ what's the matter?
[21:02:35] <PetefromTn_> Connor Sorry your house has issues man....
[21:02:35] <Connor> PetefromTn_: Yea, that sucks.. Timing couldn't be worse.
[21:03:22] <PetefromTn_> pfred1 did you not hear the conversation just now? I had a serious sick the last four days... it SUCKED BAD!!
[21:03:27] <Computer_Barf> when I did that kind of work , we often built big pvc framed plastic tarp enclosures
[21:03:36] <pfred1> PetefromTn_ like a cold?
[21:03:47] <Computer_Barf> basically make a box with an open side against the offending area of mold
[21:03:52] <Connor> PetefromTn_: Hopefully.. if The sun is shining and all the starts line up.. we'll be able to repair everything and have some money to do new kitchen cabinets and counter tops.. and maybe be able to expand my workshop.
[21:03:57] <PetefromTn_> yeah just read back a bit....
[21:04:06] <Connor> who knows.. a nice 10x22 lathe too.
[21:04:09] <PetefromTn_> that would be nice..
[21:04:21] <PetefromTn_> get that 12x36....
[21:04:25] <Connor> If it costs too much.. we might look at just getting it repaired and look for a new house.
[21:04:34] <Connor> PetefromTn_: If in the budget.
[21:04:40] <Computer_Barf> then we wore these really nice hepa face masks, professional hepa vacs, and filtering machines , tyvek suits , etc
[21:04:58] <PetefromTn_> BBL
[21:05:12] <Computer_Barf> basically cut out all the drywall, bag , vacuum , clean, bleach , sand , vac , wipe , bleach, repeat
[21:05:44] <pfred1> bleach rules
[21:05:57] <Computer_Barf> it was a super anal process, and was miserable conditions with those masks , heat, etc
[21:06:02] <pfred1> germcidal bleach
[21:06:19] <Connor> Computer_Barf: Yea.. thats interior repair.. what about stuff like floor joists etc ?
[21:06:23] <pfred1> well you miss a little bit and it just blooms again
[21:06:27] <Computer_Barf> there was always this conflict on standards on if you were supposed to use bleach or this other stuff
[21:06:46] <Connor> They're talking about going in and soda blasting..
[21:07:28] <Connor> May need to install a french drain behind the house...
[21:07:33] <Computer_Barf> we sanded 2x4's and such. Yeah , i didn't do it , but if it was bad enough they had something like sand blasting
[21:08:06] <Connor> I mean.. they're talking maybe having to replace floor joists.. that's scaring the crap out of me.
[21:08:10] <pfred1> I'm surprised they haven't developed some kind of an encapsulation proceedure
[21:08:43] <Connor> http://www.crawlspaceninja.com/image/76277748_scaled_256x192.jpg
[21:08:44] <Connor> like that ?
[21:08:50] <Connor> vs
http://www.crawlspaceninja.com/image/76277745_scaled_256x192.jpg
[21:09:38] <Computer_Barf> yeah thats the thing.. mold remediation used to not be as big a deal, but they talk about it today like its the next smoking. considering the mess katrina did to my lungs its probably true
[21:10:09] <pfred1> it is really noldy where i live
[21:10:13] <pfred1> moldy even
[21:10:18] <Computer_Barf> but yeah, i can understand how the way they treat it can be bothersome if the bill is landing on you.
[21:10:51] <Connor> I'm hoping insurance covers some of this...
[21:11:47] <Computer_Barf> does having someone inspect it create some permanent record of it existing?
[21:12:04] <Computer_Barf> I was just a worker so I didn't really learn that kind of thing
[21:12:11] <Connor> Not sure.. why?
[21:12:27] <Connor> If you sell, you have to disclose..
[21:12:35] <Connor> I'm sure.
[21:12:40] <Computer_Barf> lol yeah
[21:12:53] <Connor> like Lead paint.
[21:12:59] <Computer_Barf> but man i would be tempted to slap a coat of killz on it and ..
[21:13:24] <Connor> If it gets ANY air.. it would continue to grow.
[21:13:40] <Connor> any ways.. that's been MY week from hell.
[21:13:42] <Computer_Barf> i know they have inspectors that basically have machines that can test the load in the air
[21:14:06] <Connor> going to go find some food..
[21:14:12] <Computer_Barf> we had these huge dessicant machines that ran on propane
[21:14:50] <Computer_Barf> you could hook it up to the crawl space and feed super dry air into the space and suck it out with a fan
[21:15:11] <pfred1> it is always humid here
[21:15:47] <Computer_Barf> yeah no i mean as a temporary measure to minimize the spread and speed of damage.
[22:23:29] <jdh> Connor: how do you set the preload on the nuts?
[22:24:30] <Connor> jdh: You would have to shim / grind the spacers..
[22:24:41] <Connor> but, like i said, they were already preset
[22:24:57] <Connor> switching to ipad
[22:24:58] <jdh> no springs/bellvilles in there?
[22:25:02] <Connor> brb
[22:28:26] <Connor_iPad> So. No. Not springs or belleville washers.
[22:29:19] <skunkworks> that is how the big boys do it...
[22:29:50] <Connor_iPad> How?
[22:30:05] <jdh> I don't see how they work otherwise
[22:30:19] <jdh> unless the spacers are perfect
[22:30:38] <Connor_iPad> They're ground.
[22:30:53] <skunkworks> right - ballscrews are ground - the shims are just right.
[22:34:04] <Connor_iPad> You can see that the spacer is only screwed to the front ball nut.
[22:44:32] <skunkworks> we have some 2 inch ball screw/nuts here I should take a picture of..
[22:45:57] <Connor_iPad> Yes. You should. :)
[22:47:34] <XXCoder> .. that you made? heh
[22:48:19] <skunkworks> no. Out of random machines we have scrapped or robbed parts from.
[22:50:54] <skunkworks> not of the nut - but this is the size of the ball screws in the k&
[22:50:56] <skunkworks> t
[22:50:59] <skunkworks> http://electronicsam.com/images/KandT/conversion/xaxis/ballscrew.JPG
[22:51:26] <skunkworks> 2tpi
[22:51:35] <skunkworks> *3tpi
[22:54:13] <XXCoder> large
[22:54:32] <XXCoder> its even larger than one I saw on car sized cnc router'
[22:55:31] <Connor_iPad> Dang. That's big.
[23:01:46] <Valen> I'll take 7
[23:06:14] <zeeshan> ill take 2
[23:07:09] <skunkworks> y axis ball screw + right angle zero backlash gearset. (the pinion has an inner and outer gear and is adjusted to take the slack out.)
[23:07:11] <skunkworks> http://electronicsam.com/images/KandT/conversion/yaxis/Ygears.jpg
[23:07:16] <zeeshan> jdh it is confusing
[23:07:31] <zeeshan> but those ground spacers apparently set the preload :P
[23:07:35] <zeeshan> i still have yet to mount the new nuts
[23:07:48] <skunkworks> The z axis drive train is even more complicated..
[23:09:43] <Valen> using a spacer to set the preload on a ground ballscrew is common
[23:09:53] <Valen> I use belvilles because I use cheap screws ;->
[23:11:07] <zeeshan> i dont personally like the ground spacer stuff
[23:11:10] <zeeshan> its non adjustable
[23:12:30] <skunkworks> if you keep it oiled - it should last for a very long time..
[23:12:52] <skunkworks> it is a bearing...
[23:14:37] <Valen> its adjustable, you just put new spacers in ;->
[23:14:42] <Valen> but yea, scary lol
