[00:00:08] <Loetmichel_> btw: making the coil like a car spring and inserting it into the chimney of a small wood stove should be more efficient in harvesting heat than the simple barbecue thing
[00:00:19] <Loetmichel_> it wastes a lot of heat
[00:01:02] <Loetmichel_> i once made a second coil and set it up 5" above the first one and put them in series
[00:01:54] <Loetmichel_> (cold water-> upper coil -> lower coil-> back to the pool) and that resulted in 5°C more temperaure on the "hot" end
[00:04:37] <Jymmm> Loetmichel_: so basically the upper coil is acting as a "pre heater" for the lower coil
[00:04:47] <Loetmichel_> yes
[00:04:50] <Jymmm> k
[00:05:49] <Jymmm> Loetmichel_: I was planning on placing the coil at the bottom of the firebox (under the coals) so that when the wood diesout, it can still extract the last bits of heat left.
[00:06:19] <Loetmichel_> i dont think that'll work very well
[00:06:28] <Jymmm> whys that?
[00:07:15] <Loetmichel_> because the bigger portion of the engery is in the combustion gasses. not in the coal
[00:07:51] <Loetmichel_> the radiated heat of the stove walls is less than what flees thru the chimney
[00:07:52] <XXCoder> well if its in concerete blocks it would last quite a whule after fire burns out
[00:07:59] <Jymmm> Well, the gas is 60% of the energy compared to the solids, yes.
[00:08:52] <Jymmm> XXCoder: concrete can only withstand about 500F as I understnad it
[00:08:59] <Loetmichel_> so it would make more sense to place the heat exchanger where it can harvest as much as possible from the gasses
[00:09:07] <Jymmm> I am making firebricks though
[00:09:21] <XXCoder> hm thought it could stand up to more than that
[00:09:27] <XXCoder> how hot you plan on?
[00:09:56] <Loetmichel_> Jymmm: how good are you at welding?
[00:10:03] <Jymmm> Loetmichel_: Well, I'll try both ways, hows' that =)
[00:10:11] <XXCoder> more energy thgat way too
[00:10:19] <Loetmichel_> get some 1/4" mild steel sheets
[00:10:24] <Jymmm> Loetmichel_: EXCELLENT, since I've never wleded anything in my life =)
[00:10:48] <Loetmichel_> make a "box in a box" with around 1" of space around the inner box
[00:10:52] <Jymmm> XXCoder: A wood stove can easily get into the 800+ range without even trying
[00:11:03] <Jymmm> Loetmichel_: a reburner =)
[00:11:15] <Loetmichel_> make the inner box your fire box and fill the room between the two with water
[00:11:20] <Loetmichel_> done ;-)
[00:11:32] <Loetmichel_> thats called a "wassertasche" in german
[00:11:41] <Jymmm> Loetmichel_: If I could find a tnak, I'd just toss it in the firebox =)
[00:11:45] <XXCoder> somewhat confused, how hot does fireplace get anyway
[00:12:01] <Loetmichel_> it is readily aviable to mount into open fireplaces here
[00:12:08] <Loetmichel_> tnak?
[00:12:09] <Jymmm> XXCoder: If the sides of a wood stove are glowing orange, you've added too much fuel =)
[00:12:13] <Jymmm> tank
[00:12:16] <Jymmm> water tank
[00:12:22] <Cromaglious_> or have an air leak
[00:12:27] <XXCoder> lol ok
[00:12:30] <Jymmm> Cromaglious_: that too
[00:12:49] <Loetmichel_> Jymmm: no, the other way around
[00:12:50] <Cromaglious_> I had to fix my brothers stove..
[00:12:51] <Jymmm> XXCoder: IT's called "over firing" your wood stove
[00:12:55] <Loetmichel_> fire inside, water around it ;)
[00:13:21] <Jymmm> Loetmichel_: Yeah, but unless I had SS it would rust out on me =)
[00:13:30] <Loetmichel_> it wouldnt rust that much
[00:13:45] <Jymmm> XXCoder: I've done it not even trying
[00:13:45] <Loetmichel_> thats why i said: take 1/4" steel
[00:13:46] <Cromaglious_> his flue was 20' straight up... he had 1/2" of door gasket missing...
[00:14:01] <Jymmm> Cromaglious_: OUCH
[00:14:08] <Loetmichel_> 1/8" should be plenty for structual reasons
[00:14:22] <Loetmichel_> so the other 1/8 is for "rusting away" ;)
[00:14:23] <Jymmm> Cromaglious_: just 1/2" huh?
[00:14:29] <Jymmm> Loetmichel_: haha
[00:14:48] <Cromaglious_> just 1/2" was enough to turn the flue red up about 8'
[00:15:13] <Loetmichel_> Cromaglious_: yes, its funny what a bit of "forced air" can do
[00:15:19] <Jymmm> Cromaglious_: I kinda whine a bit when I cant clam the fire to burn all night because there is still too much air with the damper all the way closed
[00:15:21] <Cromaglious_> first fire in his stove after he moved in...
[00:15:34] <Jymmm> calm*
[00:15:40] <Loetmichel_> the usual way i start my barbecue: http://www.cyrom.org/palbum/main.php?g2_itemId=12046&g2_imageViewsIndex=1
[00:16:07] <Jymmm> you drop drones into it!!!
[00:16:08] <Loetmichel_> those quadcopters make for quite a hurricane underneath them at full throttke ;)
[00:16:14] <Loetmichel_> throttle
[00:16:31] <Jymmm> I like the drone fuel bbq idea better
[00:16:59] <Jymmm> Cromaglious_: I now keep 50lbs of sand at the ready at all times
[00:17:05] <Cromaglious_> after I replaced all the gaskets it would bank down and run for 3 days on 1'x1'x1' of oak
[00:17:46] <XXCoder> Jymmm: ya but how hot does regular fireplace get in house? because it tend to be concerete tpp
[00:17:54] <XXCoder> too
[00:17:56] <XXCoder> Jymmm: well sand can take TOOOONS of heat
[00:17:57] <XXCoder> then you can extract heat from it
[00:18:09] <XXCoder> con: probably long while to warm up
[00:18:15] <Jymmm> XXCoder: sand is to douse a firebax fire
[00:18:23] <Jymmm> firebox*
[00:18:39] <XXCoder> sure but then you can use it as heat volume
[00:18:43] <Cromaglious_> I would love to put an insert into my fireplace
[00:18:48] <Loetmichel_> XXCoder: we managed to get our 1/2" square steel bars that made up the coal tray in the fireplace burned thru
[00:18:49] <Jymmm> XXCoder: I said CONCRETE, specifically =)
[00:18:54] <XXCoder> it takes a while to heat up, but stays therre for long time
[00:18:56] <Loetmichel_> in less than half a year
[00:19:01] <Jymmm> XXCoder: not mortar
[00:19:08] <Loetmichel_> so much for heat ;)
[00:19:29] <XXCoder> heh metals have very poor heat contain
[00:19:38] <XXCoder> it conducts heat too well to.
[00:20:01] <Cromaglious_> Loetmichel_, I melted my grate burning trash and oak before I moved out of my antioch house...
[00:20:24] <Loetmichel_> Cromaglious_: it was oak here, too
[00:20:24] <Cromaglious_> warped the air damper too
[00:20:24] <Jymmm> Cromaglious_: antioch, like by richmond?
[00:20:40] <Loetmichel_> but it was an open fireplace
[00:20:47] <Loetmichel_> inside the living room
[00:20:56] <Cromaglious_> Jymmm, Out on highway 4 yep
[00:21:11] <Jymmm> Cromaglious_: Ah, I didn't relaize you lived in the bay area
[00:21:20] <Cromaglious_> I was born in the bay area
[00:21:26] <Loetmichel_> with about 120 lb of copper in the exahaust hood.
[00:21:26] <Jymmm> heh
[00:21:28] <Loetmichel_> ;-)
[00:21:32] <Cromaglious_> I live in Riverside county now
[00:21:45] <Jymmm> Cromaglious_: Norco? Corona?
[00:21:51] <Cromaglious_> Temecula
[00:21:57] <Jymmm> oh BFE
[00:22:00] <Loetmichel_> <- lived in a house once that had central electric heating
[00:22:00] <Cromaglious_> bit more highbrow
[00:22:10] <Loetmichel_> with "night current"
[00:22:13] <Cromaglious_> Loetmichel_, my condolences
[00:22:40] <Jymmm> Cromaglious_: you went south, I went north =)
[00:22:45] <Loetmichel_> meaning there were 3 1000 liters water tanks in the cellar, heated electrically over night and pumped thru the house by day
[00:22:55] <Cromaglious_> I remember house with a plaque by the front door... "This House is all electric"
[00:23:02] <Loetmichel_> and that was EXPENSIVE
[00:23:14] <Loetmichel_> so we welded together a heat exchanger for the fireplace
[00:23:56] <Cromaglious_> when the power company stopped giving them a break on the cost of power... you never saw so many gas furnances, water heater and ranges go in
[00:23:59] <Loetmichel_> ... and had a big sign beside the fireplace "FIRST START THE PUMP, THEN LITE THE FIRE!"
[00:24:11] <SpeedEvil> hah
[00:25:00] <Cromaglious_> I lved in 2 places with electric stove and heaters... both apartments... blah!
[00:25:48] <Cromaglious_> Jymm :) my folks are in Richmond, my brother in Walnut Creek
[00:26:56] <Cromaglious_> my wife and I want to retire in Morro Bay though...
[00:28:05] <Cromaglious_> but my parents are too healthy... probably both got over 20 years left in them each...
[00:29:31] <XXCoder> crom I have met some old people that seem to not age but simple sllllowly "dry". they live so long
[00:30:01] <XXCoder> like jerky, more dry, tougher as ages
[00:36:22] <Jymmm> XXCoder: lmao
[00:38:34] <XXCoder> https://www.youtube.com/watch?v=w7t_G-bk0W4 I love old goverment videos.
[00:41:19] <XXCoder> too bad some of those seem to be lost art now
[00:41:36] <XXCoder> people rather program stepper than do special gears to automate some motions
[00:42:40] <R2E4> anyone seen any new trivkins configs anywhere for two motor axis?
[00:43:06] <R2E4> for 2.7.8 pre
[00:49:27] <R2E4> Configurations with non-identity kinematics and configurations that use duplicated axis letters (for example, gantries using more than one joint for an axis coordinate) will require appropriate independent control logic to support both joint and teleop (world) jogging.
[00:49:52] <R2E4> What is that suppose to mean? will require independant control logic.
[03:47:16] <Deejay> moin
[05:44:35] <jthornton> morning
[05:45:27] <XXCoder> hey
[05:45:33] <XXCoder> im printing SCP logos lol
[05:47:28] <jthornton> cool, did you print any of the wire clips?
[05:47:55] <XXCoder> not yet lol
[05:48:02] <XXCoder> forgot about it
[05:48:07] <XXCoder> what scale did you do btw
[05:49:03] <jthornton> last was 115% but it still was a bit small
[05:50:29] <XXCoder> hm ok. weird though
[05:53:57] <jthornton> R2E4: do you mean 2.8 pre?
[05:54:10] <jthornton> or better known as master
[06:12:37] <XXCoder> Secure. Contain. Protect.
[06:57:36] <XXCoder> jthornton: http://picpaste.com/IMG_20161030_042555-q03efQAI.jpg
[06:59:08] <jthornton> cool what is it?
[06:59:39] <XXCoder> its fictional (maybe? LOL) agency Fountian that secures abnormal stuff in world
[06:59:58] <XXCoder> some of stuff they hold is really dangerous
[07:00:41] <jthornton> lol
[07:00:47] <XXCoder> this one being most famous, and basis of weeping angel in doctor who. http://www.scp-wiki.net/scp-173
[07:01:32] <XXCoder> there is 3 classes, safe,l ecluid and keter
[07:02:00] <XXCoder> that one is euclid because while it is containable intellence exists and they dont understand it fully.
[07:15:34] <SpeedEvil> 173 isn't my favourite
[07:15:55] <SpeedEvil> http://www.scp-wiki.net/scp-914 - even sort of on-topic
[07:16:15] <XXCoder> lol yeah
[07:16:36] <XXCoder> one of creepier ones is shadow girl
[07:16:52] <XXCoder> damn it can disappear anything.. besides that one scp
[07:16:59] <XXCoder> unkillable lizard
[07:18:30] <XXCoder> and easter frog geez
[07:18:38] <XXCoder> hell of gross out, that one
[07:18:58] <XXCoder> theres worse ones but that one just hit button so hard
[07:29:47] <XXCoder> SpeedEvil: this is my abostute favorite http://www.scp-wiki.net/scp-447
[07:30:02] <XXCoder> I find it really funny. and wonder what the heck would happen :P
[08:15:34] <XXCoder> oh yeah SpeedEvil you know theres scp game too?
[08:15:42] <XXCoder> never tried it, but yeah :P
[08:20:23] <SpeedEvil> I have seen it played
[08:20:49] <XXCoder> just googled youtube
[08:22:03] <XXCoder> https://www.youtube.com/watch?v=-11bFONAbzg lol
[08:23:11] <XXCoder> hew yeah gonna stop watching
[08:24:02] <XXCoder> it, like many 3d games, make me dizzy :(
[08:25:34] <JT-i3> I wonder how I had any internet on this PC with a mis-wired lan cable...
[08:25:46] <JT-i3> note to self use the cable tester when you make a cable
[08:26:18] <MacGalempsy> they work well and are cheap
[08:26:54] <JT-i3> I have a good one, just need to use it when I make a cable
[08:37:42] <JT-i3> I wish I could remember what archivist said about blocking annoying stuff on your browser
[08:37:57] <Tom_L> JT-i3 what's the latest lcnc ver you're running on anything?
[08:38:25] <Tom_L> what brouser?
[08:38:45] <Tom_L> i use ABP
[08:38:48] <Tom_L> on ff
[08:39:10] <JT-i3> on firefox
[08:39:16] <Tom_L> add block plus
[08:39:29] <JT-i3> he had a link to some list that blocks somehow
[08:39:59] <Tom_L> in the extensions area
[08:40:07] <Tom_L> oh
[08:40:12] <JT-i3> some linux thing
[08:40:26] <Tom_L> this works pretty well
[08:40:29] <JT-i3> the hosts file
[08:41:00] <Tom_L> it has a warning removal list
[08:41:11] <JT-i3> https://delightlylinux.wordpress.com/2012/05/31/block-ads-using-the-hosts-file/
[08:41:46] <JT-i3> http://winhelp2002.mvps.org/hosts.htm
[08:42:24] <Tom_L> you could ask rue
[08:42:28] <Tom_L> he does that as well
[08:42:34] <Tom_L> pretty sure
[08:46:26] <tjtr33> CaptHindsight, minnie pearl sez HowDEE
[08:47:05] <tjtr33> i'm reading logs, got a long way to go to 'now'
[08:52:14] <archivist> JT-i3, something on the lines of http://www.guidingtech.com/4868/edit-hosts-file-block-websites/
[08:53:31] <archivist> does allow selective blocking
[08:55:20] <archivist> trouble with adblock software is they do tracking as well/instead of
[08:58:36] <JT-i3> thanks
[09:30:34] <JT-i3> XXCoder: scaling the part has some undesirable effects
[09:31:55] <Jymmm> I think I might have found my new "reverse lights" for the car... https://www.amazon.com/Sucool-Square-Tractor-vehicles-automative/dp/B00NIHOZY4/
[09:34:55] <Jymmm> CaptHindsight: I did come across some "spot" lights in a smaller configuration, not a "light bar" one.
[09:38:50] <Jymmm> It's 7am and it's STILL dark outside =(
[09:40:10] <Jymmm> CaptHindsight: Spot https://www.amazon.com/4200Lumens-Wrangler-Trailer-Fishing-Tractor/dp/B00Q683YZS/
[09:51:10] <BeachBumPete> its amazing how good some of the newer LED lighting coming out is..
[09:53:13] <BeachBumPete> I just bought a shop lite/work lite that has magnetic mount and hooks to hang in about any conceivable way and it is both brighter, more efficient, and uses less energy than the old Halogen shop light I used to burn myself on regularly :)
[09:55:51] <Jymmm> BeachBumPete: This is the one I bought and installed behind the grill of my SUV last year https://www.amazon.com/TMH-Motorbike-Motorcycle-Excavator-Bulldozer/dp/B00KQXKG46/
[09:56:14] <BeachBumPete> nice I would bet that it is blindingly bright huh
[09:56:39] <Jymmm> BeachBumPete: But, I just found this one for $10 cheaper https://www.amazon.com/gp/product/B00WE47FVM/
[09:56:45] <BeachBumPete> what kind of SUV?
[09:57:38] <BeachBumPete> I wonder what the longevity of these things is going to be..
[09:58:41] <Jymmm> BeachBumPete: 2001 Ford Expedition. My headlamps were never that good, even when I drove it off the lot brand new. The lens are now yellowed, replacement lens are $40 and would be the same results, this was $40 and far brighter, a no brainer. I almost hit 6 deer in a month because I couldn't see them off in the distance.
[09:58:52] <BeachBumPete> the LED bulbs I have been installing throughout my new home here say they will last 8-10 years? I know they do not get hot at all like the incandescents did
[09:59:58] <BeachBumPete> seems like those deer aim for you sometimes doesn't it.
[10:00:15] <BeachBumPete> we killed a few in the time we lived in Tennessee..
[10:00:38] <Jymmm> They just dont know which way to go. They start to go back ino the brush, then zoom out at the last minute.
[10:00:46] <BeachBumPete> my wife hit one with my 93 Probe GT ripping the headlight off the right side and cracking the windshield
[10:00:56] <BeachBumPete> then she hit one with my Bronco
[10:01:18] <BeachBumPete> I hit one with my wife in my custom lifted offroad Suzuki Samurai with my wife in the car
[10:01:56] <BeachBumPete> the only good thing is unlike out west the deer there are not too big generally
[10:02:10] <BeachBumPete> like hitting a tall skinny dog mostly
[10:02:19] <Jymmm> I used a relay and wired it to the highbeam so I can flash he light or leave on solid
[10:02:24] <BeachBumPete> but they can still mess up your car
[10:03:05] <BeachBumPete> our neighbor in Tennessee hit one in his old pickup truck and it jumped at the last minute going thru the windshield and nearly killed him
[10:03:52] <Jymmm> If I get another, I'd wire it to the reverse lights and maybe mount it UNDER the rear bumper... it gets SUPER dark going in reverse and I back into my long driveway.
[10:04:12] <BeachBumPete> nothing wrong with some good lighting
[10:04:18] <Duc> enleth: the mill is starting to look good
[10:04:36] <BeachBumPete> I used to have a bunch of rock lights on my suzuki samurais for seeing under the truck out on the trail
[10:04:41] <Jymmm> I'd perfer to mount it to the roof, but I'm chicken shit to drill =)
[10:04:52] <BeachBumPete> does your truck have a roof rack?
[10:05:16] <Jymmm> a luggage rack, but it's not the mounting, but running power to it
[10:05:26] <BeachBumPete> ah
[10:06:03] <BeachBumPete> my neighbor was showing me this torch light he got from some online chinese supplier
[10:06:14] <BeachBumPete> this thing is amazingly bright and powerful
[10:06:28] <BeachBumPete> it has a lens that both directs and adjusts the beam
[10:06:41] <BeachBumPete> I need to find out where he got it
[10:06:51] <BeachBumPete> he said it was like 20 bucks
[10:07:34] <sync> I like the 90mm hella led retrofits
[10:07:47] <Jymmm> BeachBumPete: $3.43 http://www.dx.com/p/sipik-sk68-cree-q3-wc-120-lumen-convex-lens-led-flashlight-black-1-aa-1-14500-39585
[10:08:06] <BeachBumPete> do you have that one?
[10:08:13] <Jymmm> Nope,
[10:08:24] <Jymmm> but it has 454 reviews
[10:08:32] <BeachBumPete> it looks something like that but was smoother looking and longer body
[10:08:37] <Jymmm> and only takes ONE AA battery
[10:08:54] <enleth> Duc: it would be better if the old control still worked, it will be a huge PITA to reattach the original keyboards and displays and emulate some of the old behavior
[10:08:56] <BeachBumPete> yeah that is what is so amazing about this stuff
[10:09:08] <BeachBumPete> so little power required
[10:09:22] <Duc> enleth: why even try. Did you see the panel I made to replace my items
[10:09:26] <BeachBumPete> used to take a maglight with six cells to put out that much light
[10:09:28] <Jymmm> All my flashlights are now 18650 based
[10:09:37] <enleth> Duc: computer monitors and keyboards make for very shitty DROs
[10:09:40] <BeachBumPete> yeah rechargables
[10:10:04] <sync> http://www.hella.com/agriculture/assets/media_global/977_90mm_Gesamtbroschuere_HELLA_EN.pdf those are really nice
[10:10:19] <enleth> Duc: and this mill is still supposed to be used as a manual machine as well as CNC
[10:10:36] <Jymmm> sync: HELLA's are hella expensive
[10:10:46] <BeachBumPete> hell yeah they are
[10:10:54] <Duc> enleth: But if you puttting the backbone as linuxcnc then it doesnt matter what you use. a 22in monitor makes it easy to read the DRO
[10:10:57] <sync> it's adequate for what they do
[10:11:11] <Jymmm> sync: I could buy 2-3 of the china specials for the cost on one HELLA
[10:11:12] <sync> they actually put the light where you need it
[10:11:32] <enleth> Duc: I prefer separate displays and physical keys
[10:11:35] <enleth> Duc: especially the latter
[10:11:50] <Jymmm> sync: Not saying they're bad, on not better than the HELLA, but way out of my budget
[10:11:58] <enleth> Duc: it would be even more of a PITA to make a DRO keyboard from scratch
[10:12:18] <Duc> enleth: most of my functions are controlled by switches and knobs. Monitor is just a display
[10:12:31] <enleth> Duc: do you have a DRO for manual operation?
[10:12:41] <enleth> Duc: with stuff like center finding etc.?
[10:14:06] <enleth> I can repurpose the programming keyboard (replacing the glyphs on the keys obviously) for those
[10:14:11] <sync> Jymmm: too bad, I used them a lot on the rally cars, the hid units are insanely bright
[10:14:18] <Duc> enleth: i purchased a old control panel and just rewired it to a 7i84
[10:14:27] <enleth> It will be a PITA, but using a PC keyboard for that is a bigger PITA
[10:14:44] <enleth> Duc: uh, and I have a panel already
[10:14:57] <enleth> there will be a monitor above it or something like that
[10:15:02] <Jymmm> sync: I avoid HID like the plague, way too much to them for SPOF's
[10:15:29] <Jymmm> sync: I dont need a fucking cooling fan on my lights damnit =)
[10:15:45] <sync> there is no fan on the hellas
[10:16:05] <Jymmm> sync: Not on the light itself, but the controller
[10:16:06] <BeachBumPete> they are quite complex to install
[10:16:13] <Duc> enleth: http://i1221.photobucket.com/albums/dd465/shefron/Machinery/20140427_154530_zpsrg0mpczc.jpg
[10:16:26] <sync> no Jymmm
[10:16:31] <sync> it is just a stainless box
[10:16:33] <enleth> Duc: still not a DRO
[10:16:34] <Duc> enleth: http://i1221.photobucket.com/albums/dd465/shefron/Machinery/20140427_154435_zpszr9h8w6n.jpg
[10:16:48] <Duc> enleth: the DRO is on the monitor screen.
[10:17:03] <Jymmm> sync: I dont need no stickin box either, just two wires tyvm =)
[10:17:13] <enleth> Duc: and where are buttons for typical DRO operations during manual machining?
[10:17:36] <Duc> enleth: such as?
[10:17:36] <sync> well, we tried the led ones and they were just not bright enough Jymmm
[10:17:50] <Jymmm> sync: Plus brighter also means more current draw and I like a balance between the two
[10:18:10] <enleth> Duc: zero an axis, switch between absolute/incremental, switch between machine and datum coordinates, find center of part, etc.
[10:18:22] <Jymmm> sync: I totally get it, really. They are far better for light output no doubt. I live in the forest and I totally get it.
[10:19:34] <Jymmm> sync: I could add a 2nd 20" led and double the brightness, or get two 10" to get wider area and overlap as I see fit
[10:19:38] <enleth> Duc: my point is that I want stuff like that to work without touching the PC keyboard and mouse(/other mouse-like device)
[10:19:45] <Duc> enleth: the buttons on the panel can be programmed for those steps. I dont have mine setup yet but I do have the jog incr, max jog speed, axis selection, program speed already setup
[10:20:41] <enleth> Duc: well that's cool, but I don't really see the point you're trying to get across
[10:21:53] <Duc> enleth: no clue at this point. Im so confused this morning
[10:22:18] <enleth> Duc: I have a rather well-defined requirement about an emulated DRO for manual machining, with physical buttons, and I have the original TNC panel that can be repurposed for this, so I'm definietely not going to *replace* it with a monitor
[10:22:27] <enleth> besides, the biggest monitor I could stick there is 14"
[10:22:38] <enleth> and I don't have time to replace the whole pendant
[10:22:58] <BeachBumPete> I gotta build a whole pendant for my CNC lathe :)
[10:23:06] <enleth> so a monitor will be attached on top or to the side of the pendant
[10:23:09] <sync> Jymmm: yeah, probably. ime focused beams are more useful than the bars, we tried one and it only made the near field brighter which does not help when you are hammering down forest roads at 230kmh
[10:23:23] <R2E4> Hey Pete......
[10:23:30] <R2E4> Tennessee Pete?
[10:23:37] <Duc> I do need to buy one of the handheld units for controlling stuff. at times it would come in handy
[10:23:41] <BeachBumPete> R2E4 hey R2
[10:23:55] <R2E4> I see you survived......
[10:23:59] <BeachBumPete> no longer tennessee pete
[10:24:07] <BeachBumPete> oh yeah we are surviving
[10:24:25] <R2E4> I was down there fro a week and a half
[10:24:28] <BeachBumPete> enjoying the beautiful weather right now ;)
[10:24:37] <BeachBumPete> oh yeah where?
[10:25:47] <R2E4> clearwater
[10:25:59] <R2E4> My whole family is there
[10:26:05] <BeachBumPete> I was stationed in St. Pete for a couple years
[10:26:10] <R2E4> howz your lathe coming along?
[10:26:13] <BeachBumPete> dated a girl from Dunedin
[10:26:26] <BeachBumPete> its very nice there too
[10:26:26] <R2E4> haha, I was born and raised in Largo
[10:26:43] <BeachBumPete> I like the pass a grill beach area
[10:26:59] <R2E4> yeah...... its all grown up like crazy there
[10:27:15] <BeachBumPete> it is everywhere now it seems
[10:27:20] <BeachBumPete> but it is still nice
[10:27:36] <R2E4> howz your lathe coming along?
[10:27:49] <BeachBumPete> here on hutchinson Island where I have been working it is very nice and reasonably quiet
[10:28:08] <BeachBumPete> well I finally got both the Lathe and the VMC out of storage and moved into my shop
[10:28:25] <BeachBumPete> the lathe is off the skids and is sitting there waiting for me to get back to work on it.
[10:28:29] <R2E4> You putting mesa stuff on the lathe?
[10:28:46] <BeachBumPete> I have everything for it except the spindle drive and a Z axis ballscrew
[10:28:58] <R2E4> you using 5i25 or the ethernet one?
[10:28:59] <BeachBumPete> yeah all mesa stuff and DMM servos and drives all brand new
[10:29:31] <R2E4> What are you doing with the old servo and drives?
[10:29:36] <BeachBumPete> I was planning on using the same 5i25/7i77 combo that worked so well on the Cinci
[10:29:50] <BeachBumPete> it never had any I bought the lathe gutted
[10:30:02] <R2E4> yeah, I have another VMC coming up but am pondering the ethernet or the 5i25......
[10:30:11] <BeachBumPete> it only had some small electronics parts in the cabinet
[10:30:20] <R2E4> My vmc is strill great and that is a great combo but the ethernet would be nice
[10:30:39] <BeachBumPete> I just had the 5i25/7i77 here already
[10:31:11] <R2E4> I have a 7i77 already here, so I might just get the 5i25
[10:31:16] <BeachBumPete> actually I blew up my 7i77 awhile back screwing around in the Cinci and send it back to mesa and bought another one while they repaired it
[10:31:21] <R2E4> I have a bridgeport to do also.
[10:31:35] <R2E4> CNC bridgeport series 1 boss 9
[10:31:36] <BeachBumPete> then I got a new 7i77
[10:32:00] <R2E4> lol, howd you blow it up?
[10:32:03] <BeachBumPete> I would be just happy to have the VMC and the lathe finished
[10:32:27] <BeachBumPete> well I was playing with the low voltage DC and trying to adjust some wiring and screwed up LOL
[10:32:32] <BeachBumPete> its been fixed awhile now
[10:32:39] <R2E4> lol
[10:32:50] <R2E4> That machine on 3 phase?
[10:32:58] <BeachBumPete> no I don't want 3 phase
[10:33:07] <enleth> R2E4: my Series 1 MDI is almost working now
[10:33:10] <BeachBumPete> both will run on single phase the CInci has been on it for awhile
[10:33:16] <enleth> R2E4: on a 7i77, that is
[10:33:32] <R2E4> oh yeah, what servo is on that series 1
[10:33:47] <R2E4> SEM?
[10:34:28] <BeachBumPete> I need to extricate my azz from the couch here and get out there and work on the machines
[10:34:36] <BeachBumPete> they are not gonna retrofit themselves :)
[10:34:37] <R2E4> hahaha
[10:34:50] <R2E4> your vmc is done no?
[10:35:02] <BeachBumPete> well define done..
[10:35:15] <R2E4> yeah, my toolchanger is still not working
[10:35:23] <BeachBumPete> it was working before I moved it
[10:35:30] <BeachBumPete> toolchanger is still inop
[10:35:37] <BeachBumPete> but I was using it all the time
[10:35:59] <BeachBumPete> now I had to relocate the huge electronics cabinet on the back to allow it to fit under a standard garage door
[10:36:12] <R2E4> oh shit,
[10:36:18] <BeachBumPete> so I had to disconnect a bunch of stuff and move some wiring to get it to work
[10:36:19] <R2E4> have to rewire everything?
[10:36:25] <BeachBumPete> no just move some things
[10:36:33] <BeachBumPete> it was not that bad really
[10:36:53] <BeachBumPete> it was far more difficult to make the bracketry to support the cabinet and relocate it
[10:37:08] <R2E4> I just loaded the new pre with JA merged.
[10:37:10] <BeachBumPete> but it is solid as hell now with heavy duty brackets in three places
[10:37:33] <BeachBumPete> I need to get it going again I have a BUNCH of customers nagging me for work right now
[10:37:51] <R2E4> thats a good nag....
[10:38:23] <BeachBumPete> yeah it sure is
[10:38:31] <BeachBumPete> so I need to get it going
[10:38:50] <BeachBumPete> still working on the sub panel for the electronical
[10:39:06] <BeachBumPete> got the 100 amp breaker and the 60 and 40 for the sub and the box mounted up
[10:39:50] <BeachBumPete> Im a wee bit nervous about hooking to the big breaker because the mains come into this box and run under the breakers right near where I will be working
[10:40:17] <BeachBumPete> stupid layout
[10:40:24] <BeachBumPete> dunno why they do it that way
[10:40:27] <R2E4> yeah but you have a disconnect switch before the machine?
[10:40:50] <BeachBumPete> well the machine has the main disconnect and the sub panel will have the breakers on it
[10:41:36] <BeachBumPete> I am talking about working inside the main electrical panel inside the house
[10:41:45] <BeachBumPete> I got a pic somewhere
[10:42:15] <R2E4> yeah, I put an new control box external to the drives and power stuff. I dont have to go into the main control box.
[10:42:24] <BeachBumPete> http://i.imgur.com/wDo8B6K.jpg
[10:42:32] <R2E4> oh.... yeah, thats a bit nerve racking
[10:42:46] <BeachBumPete> see the two big heavy cables going under and around the left side
[10:42:48] <R2E4> I installed all the 600v, trannys, stuff here in my shop
[10:43:18] <R2E4> yeah thats the main feed
[10:43:37] <BeachBumPete> yup and the second 220 volt breaker down on the left side is the one I am swapping out
[10:44:04] <BeachBumPete> its actually UNDER there a bit so it may just be me being a whiney ass
[10:44:05] <R2E4> lol, not too much left in that panel. You putting a sub in the garage?
[10:44:15] <BeachBumPete> yeah that is what I am talking about
[10:44:23] <BeachBumPete> I am adding the 100 amp breaker to power the sub
[10:44:39] <R2E4> Sure you have the right guage?
[10:44:42] <BeachBumPete> I was going to swap the whole panel but its such a PIA
[10:44:52] <BeachBumPete> the wire?
[10:44:57] <R2E4> yeah, that would suck.
[10:45:41] <BeachBumPete> the wires coming out of that breaker go to a non existant well pump and we are now on city water and sewer so its not used any more
[10:46:05] <BeachBumPete> so the breaker will be replaced and new wires going out the side of the box to the sub panel
[10:46:09] <R2E4> no I mean the cable your running to the new sub panel
[10:46:26] <BeachBumPete> yeah I have some very heavy cable from the old setup in Tennessee
[10:46:43] <BeachBumPete> its a bitch to work with but its whats necessary
[10:47:07] <BeachBumPete> I don't recall the gauge
[10:47:08] <R2E4> 220 at 100 amps is 4 guage wire if it is copper
[10:47:16] <BeachBumPete> that sounds right
[10:47:20] <BeachBumPete> it is copper
[10:47:44] <BeachBumPete> I used the same stuff to run the VMC in the house in Tennessee
[10:48:23] <R2E4> Yeah, I thought about putting the VMC in the house and the wife in the shop also.......
[10:48:42] <R2E4> that didnt go very well......
[10:48:43] <R2E4> lol
[10:49:05] <BeachBumPete> I have it in the plastic conduit with single lead wires for each
[10:49:25] <BeachBumPete> my wife is actually fine with it we almost never parked out cars in the garage anyway :)
[10:49:28] <R2E4> I have a guy wanting me to do some lower receivers for ar-15
[10:49:35] <BeachBumPete> LOL so do I
[10:49:45] <R2E4> huh?
[10:49:46] <BeachBumPete> my friend in Tennessee I used to work with
[10:49:48] <R2E4> really?
[10:49:54] <R2E4> thats funny
[10:49:55] <BeachBumPete> he is makign some now and wants me to make them
[10:50:15] <BeachBumPete> he works for a company that makes them but he wants to do billet custom ones or something
[10:50:16] <R2E4> the problem is the magazine pocket
[10:50:23] <BeachBumPete> yeah
[10:50:30] <BeachBumPete> some guys use a fourth
[10:50:34] <BeachBumPete> and a custom fixture
[10:50:57] <R2E4> I am getting a wire edm for that, the guy is going to buy it and out it in my shop....lol
[10:50:58] <BeachBumPete> he swears he can sell the hell out of them
[10:51:11] <BeachBumPete> that should work nicely
[10:51:19] <BeachBumPete> just drill a long hole and string it up
[10:51:26] <R2E4> he wants them 80%?
[10:51:40] <BeachBumPete> does your machine self string like some I have heard can do?
[10:51:58] <R2E4> no, it is a small one.
[10:52:20] <R2E4> I can do 8 X 10X6, something like that
[10:52:26] <BeachBumPete> there was a guy near me in Tennessee that had a small shop with like six EDM machines
[10:52:42] <BeachBumPete> all mitsubishi I think it was
[10:52:50] <R2E4> You cna charge the hell out of those jobs, because there are not many people that do it
[10:53:05] <R2E4> its too specialized.
[10:53:23] <R2E4> Are you going to do them?
[10:53:32] <R2E4> Do you have a model of it yet>?
[10:53:42] <BeachBumPete> I have had several people approach me about making lowers but there are already tons of people making them I thought it would not pay too well
[10:54:11] <R2E4> I am going to get 120.00 each which is not too bad
[10:54:12] <BeachBumPete> I could see some custom stuff being more my style but I don't know
[10:54:29] <BeachBumPete> you doing 80 percenters?
[10:54:34] <R2E4> yeah
[10:54:48] <BeachBumPete> ah okay those already have the pocket tho right
[10:55:02] <R2E4> No I am starting from billet
[10:55:18] <BeachBumPete> you are going to MAKE the 80 percent lowers from billet?
[10:55:24] <R2E4> yes
[10:55:29] <BeachBumPete> wow thats unusual
[10:55:36] <R2E4> why?
[10:55:38] <BeachBumPete> most are forged or cast or whatever
[10:55:55] <BeachBumPete> and they are quite cheap
[10:56:03] <R2E4> Some are some are machined from billtet, the expensive ones
[10:56:07] <BeachBumPete> but I am no expert whatsoever
[10:56:36] <R2E4> The forged ones are cheap, very pourus
[10:56:39] <BeachBumPete> the place he is working for has to serialize and everything
[10:57:00] <R2E4> up here 80% is as far as I can go.
[10:57:18] <R2E4> Not yet considered a firearm.
[10:57:18] <BeachBumPete> ah
[10:57:36] <R2E4> So I dont have to serialize them.
[10:57:54] <BeachBumPete> I don't know if I will do it or not
[10:58:02] <R2E4> Thinking of 1911's also, he said he could sell the shit out of those,.
[10:58:08] <BeachBumPete> they are quite complex actually
[10:58:12] <R2E4> yeah
[10:58:18] <BeachBumPete> the buffer hole threading etc
[10:58:28] <BeachBumPete> several different setups
[10:58:34] <BeachBumPete> unless you have a rotary axis
[10:59:06] <R2E4> I am getting a 4th axis servo
[10:59:07] <BeachBumPete> nothing crazy but not simple either
[11:00:01] <R2E4> oh its going to be ibnteresting
[11:00:24] <BeachBumPete> lots of shops making gun parts nowadays :)
[11:00:42] <R2E4> your scopes turned out nice......
[11:00:54] <BeachBumPete> which ones?
[11:00:59] <R2E4> I was in awe of those.....
[11:01:09] <R2E4> The ones you did in Tennessee
[11:01:13] <BeachBumPete> you mean the scope wheels?
[11:01:17] <R2E4> yeah
[11:01:28] <BeachBumPete> oh yeah thanks man I worked pretty hard on those
[11:01:33] <BeachBumPete> I used to make them all manually
[11:01:54] <BeachBumPete> I used a super spacer and a bunch of custom radius turning tools on the lathe
[11:02:10] <BeachBumPete> pretty time consuming but it was fun
[11:02:27] <BeachBumPete> now I am making them with the CNC stuff its a bit easier
[11:02:34] <BeachBumPete> and I can do some stuff I was unable to do before
[11:02:39] <R2E4> You have a tumbler?
[11:02:45] <BeachBumPete> no not yet
[11:04:18] <BeachBumPete> well I better get out there and get some work done on the machines. Nice chatting with you R2 hope your AR work goes well for you...
[11:04:41] <R2E4> yeah, see ya man. take care
[11:04:42] <enleth> R2E4: yep, SEM MT30H4-44
[11:04:59] <R2E4> they torque dc servos?
[11:05:14] <enleth> R2E4: I removed the original Bosch Z15-1A servo drive already and installed one Copley Controls 423 drive, two more to go
[11:05:24] <enleth> no, 44V/1000RPM
[11:06:05] <R2E4> Does your have the air speed motor for the spindle?
[11:06:28] <enleth> yep, but I removed it, the whole VarSpeed transmission is completely clapped out
[11:06:36] <enleth> I'll have to replace it with a toothed belt
[11:06:47] <R2E4> OH, thats what I wanted to know. How did you do that?
[11:07:07] <R2E4> Just remove the whole clutch mechanism alltogether?
[11:07:23] <R2E4> Replace it with a special pully?
[11:07:35] <R2E4> Then run the motor off a vfd or something?
[11:07:41] <enleth> pretty much
[11:07:55] <enleth> I've got a VFD already, one of the first things I did to this mill
[11:08:26] <enleth> I found a transmission ratio for varispeed that generates the least noise and vibration, close to the top speed
[11:08:35] <enleth> set it to that and left it there
[11:08:46] <R2E4> Mine is still working of the old boss 9 control and I am drip feeding it. but the spindle is making that noise and the air speed controller is BS, never can get the correct speed.
[11:08:59] <enleth> there's a worm gear by the indicator plate, so it keeps the setting without any drivting
[11:09:13] <enleth> *drifting
[11:09:30] <enleth> you can just unbolt the air motor and attach something electrical there
[11:09:42] <enleth> machining an adapter plate should be simple enough
[11:09:43] <R2E4> 1 7i77 I would imagine is enough
[11:09:56] <enleth> do you have a VFD?
[11:10:00] <R2E4> yes
[11:10:10] <enleth> then don't bother with varispeed at all
[11:10:19] <R2E4> Mine is running on single phase now
[11:10:23] <enleth> unless yours is in a very good condition
[11:10:38] <R2E4> no its not..... very sloppy
[11:10:56] <enleth> mine isn't and while I appreciate the curiousity factor of this solution, I can't afford the $1000 it would take to restore it
[11:11:42] <R2E4> You putting a reduction with the pullys?
[11:12:09] <R2E4> For more torque? I am afraid when running slower speed the torque wont be there.
[11:12:20] <enleth> use the backgear for torque
[11:12:36] <R2E4> ah ok
[11:12:57] <R2E4> So your going with 1:1
[11:13:43] <enleth> right now I'm getting about 3500RPM without backgear and the motor is 1440 or 1730RPM, I can't remember which
[11:13:59] <enleth> so it's actually 1:2
[11:14:23] <enleth> I'm dialing it down with a VFD and using the backgear
[11:14:33] <enleth> the latter does a 9:1 reduction
[11:14:54] <enleth> which comes out as 4.5:1 at the spindle relative to the motor
[11:15:56] <R2E4> you should be able to get 5000 then
[11:16:23] <enleth> after I replace the varispeed, sure
[11:16:31] <enleth> but I don't want to run it so fast now
[11:16:48] <enleth> it gets noisy enough to vibrate the whole mill at full speed
[11:17:16] <R2E4> yeah, I cant wait to get mine done. I havent started yet....lol
[11:18:03] <enleth> anyway, right now I'm more preoccupied with the servo drive replacement
[11:18:15] <R2E4> yeah.....
[11:18:39] <R2E4> Replacing the EA board I presume....
[11:18:39] <enleth> I'm building a hodgepodge of 48VDC telecom power supplies to power them
[11:18:45] <R2E4> or removing it
[11:18:50] <enleth> EA board?
[11:19:07] <R2E4> the board with the relays and shit in the back panel
[11:19:19] <enleth> why would I do that?
[11:19:30] <enleth> those relays are perfectly fine
[11:20:15] <R2E4> oh, there is some coms stuff that communicate with the drivers I think, not all wired relays.
[11:20:37] <enleth> R2E4: http://imgur.com/a/FxxAs
[11:20:54] <enleth> the last photo shows the control enclosure
[11:21:12] <enleth> you can see the first servo drive installed and some space for the other two
[11:21:25] <enleth> everything above those is relays and contactors
[11:21:30] <enleth> and they are staying
[11:22:18] <R2E4> oh, mine is not like that
[11:22:20] <enleth> thanks to them, I can power it up with no control at all and have working handwheels, axis brakes and endstops
[11:23:00] <enleth> I would be *very* uncomfortable setting up a machine like that with software endstops
[11:23:31] <enleth> let alone a software estop
[11:23:44] <R2E4> Can you raise the knee?
[11:24:06] <enleth> no, it's not powered and I haven't bothered to motorize it yet
[11:24:15] <enleth> there's always someone around to help with cranking
[11:24:20] <R2E4> hahaha
[11:24:41] <enleth> worst case, someone's on cranking duty for the evening
[11:25:13] <R2E4> thats a nice project.....
[11:25:43] <R2E4> I cant believe how rock solid the mesa stuff is.
[11:26:10] <R2E4> I did my VMC 2years ago and havent had one problem.......
[11:26:18] <R2E4> with anything
[11:26:32] <R2E4> (pun intended...)
[11:27:01] <enleth> if only there wasn't an $60 USPS charge, VAT and duties to be paid for every order
[11:27:13] <R2E4> I hate that.....
[11:27:29] <enleth> there's supposedly some EU distributors
[11:27:41] <enleth> but their prices are even worse than that
[11:27:58] <R2E4> what about JT? He doesnt use UPOS does he?
[11:28:24] <Tom_L> i think he does
[11:28:46] <enleth> I don't think it's going to be any cheaper to use anything else
[11:30:03] <R2E4> ok gots to get back to the grind. Have a Joint-axes dual axis gantry router to finish.
[11:32:14] <zeeshan> howdy
[11:44:31] <JT-i3> hi
[12:01:14] <Tom_L> hey
[12:40:33] <JT-i3> hmm, the display works with my extra ramps board... time to look at the borked one
[12:44:37] <Tom_L> display or ramps board?
[12:45:54] <JT-i3> the display works on one ramps but the one that came with the printer it quit and has been flaky
[12:46:28] <Tom_L> 4 line?
[12:46:39] <Tom_L> i bet i have a few extra
[12:46:58] <JT-i3> 4 line smart controller
[12:47:28] <Tom_L> mine's kinda stupid
[12:47:50] <JT-i3> the display works on one ramps so I don't think the display is bad and the ramps board runs so...
[12:48:17] <Tom_L> check the pin solder job
[12:57:23] <JT-i3> looks good to me
[12:57:31] <JT-i3> going to swap cables next
[12:57:42] <JT-i3> no can't be cables they work on one
[12:57:49] <Tom_L> mmm
[12:58:09] <Tom_L> firmwares both the same?
[12:59:33] <JT-i3> yep
[13:00:36] <Jymmm> Well, first test of mortar/perlite "firebrick" is in molds drying.
[13:01:27] <Jymmm> Never worked with mortar before, man it needs VERY little water surprisingly
[13:02:21] <Tom_L> jup
[13:02:41] <tjtr33> kiln, furnace, or pizza oven?
[13:03:08] <Tom_L> pizza oven of course!
[13:03:56] <Jymmm> I wish!
[13:04:13] <Jymmm> to line a wood burning firebox
[13:05:03] <Tom_L> using firebrick too or just mortar?
[13:05:26] <Jymmm> Using mortar to bind the perlite
[13:07:49] <Jymmm> Tom_L: Not sure if it's legit, but sounds like it (read the comments too) https://www.youtube.com/watch?v=ZZAoohv4ku8
[13:08:05] <Tom_L> no sound
[13:10:28] <tjtr33> clay perlite bricks diy. thanks jymmm, always interesting http://www.info.bioenergylists.org/stovesdoc/Ogle/Clay/MAKING%20LIGHT%20WEIGHT%20REFRACTORY%20CERAMIC.pdf
[13:13:36] <JT-i3> hmm the symtom I have points to the ramps is not seeing the lcd
[13:14:14] <Tom_L> it's just a prewired data cable?
[13:14:18] <Tom_L> nothing to mix up...
[13:14:38] <Tom_L> beep test the wiring from pin to other pin
[13:15:04] <JT-i3> yea 10 pin with a key, I have more to try
[13:15:14] <JT-i3> but the cables work on one ramps board
[13:16:12] <Tom_L> no bad solder joints on the avr itself?
[13:17:14] <JT-i3> https://reprapchampion.com/products/lcd-2004-smart-display-controller-for-ramps-1-4-reprap-3d-printer-electronics?utm_medium=cpc&utm_source=googlepla&variant=7733035715&gclid=COSWpZyLg9ACFYOFaQodbc0Pag
[13:17:52] <JT-i3> I can only check the outsides of the controller
[13:18:11] <Tom_L> but you said it worked on one
[13:18:19] <Tom_L> so it's likely not the lcd controller
[13:18:22] <JT-i3> yep it works on one
[13:18:44] <Tom_L> or is that the whole controller board?
[13:18:48] <JT-i3> and the ramps 1.4 plus is a single board
[13:19:14] <Tom_L> what are the backside plugs for?
[13:19:18] <Tom_L> the hbridges?
[13:20:05] <Tom_L> i see.. the board plugs into the L card that plugs into the 2560
[13:20:07] <Tom_L> ?
[13:22:04] <JT-i3> https://www.aliexpress.com/item/New-Version-3DYMY-Ramps1-4-Plus-3D-printer-control-board-Mega-2560-R3-motherboard-RepRap-Ramps1/32504151046.html?spm=2114.01010208.3.1.Ufwuu6&ws_ab_test=searchweb0_0,searchweb201602_2,searchweb201603_1&btsid=a38d404d-d236-4057-aa28-291cfabe6e7b
[13:22:10] <JT-i3> that's the ramps board
[13:23:18] <Tom_L> yeah, hasn't changed too much from what i remember
[13:29:04] * JT-Shop has to give up on it for a while and get some ladder written
[13:50:32] <Jymmm> It's raining so hard (volume primarily) that the gaage is starting to flood and there's not a thing I can do about it right now *sigh*
[13:50:58] <Tom_L> get out the canoe
[13:57:39] <zeeshan> bail bucket
[13:57:46] <zeeshan> no need to stop canoeing!
[14:00:13] <zeeshan> Tom_L: retrofit my lathe plz
[14:00:13] <zeeshan> ;D
[14:20:38] <JT-Shop> would you believe a bad power supply connected to a PLC that was connected to a PC via a USB port could make a laptop go nuts and reboot
[14:21:04] <JT-Shop> spend all day yesterday figuring that out
[14:24:59] <JT-Shop> I guess the SPI chip took a walk on the ramps board
[14:25:16] <CaptHindsight> quality!
[14:26:47] <CaptHindsight> in the old days you could warn people about crappy products
[14:29:46] <Tom_L> zeeshan your lathe is too honkin big!
[14:34:02] <Tom_L> JT-Shop, i wonder what they need a spi chip on it for
[14:37:07] <CaptHindsight> Tom_L: http://notserpe.blogspot.com/2012/05/ramps-14-schematic-errors.html it's just for the AUX-3 connector
[14:37:28] <JT-Shop> I think that is what they use to communicate to the smart controller but I may be wrong
[14:38:06] <CaptHindsight> it's passive, the SPI controller is in the microcontroller on the duino
[14:38:19] <JT-Shop> ah
[14:38:42] <Tom_L> oh the one on the 2560?
[14:39:08] <JT-Shop> what is a 2560?
[14:39:14] <Tom_L> the avr chip
[14:39:19] <JT-Shop> ah
[14:39:33] <Tom_L> read what it says on it's lid
[14:40:00] <JT-Shop> oh yes it is a mega 2560
[14:40:49] <CaptHindsight> mega 2560 schematic http://www.gridgit.com/postpic/2012/10/arduino-mega-2560-schematic_432700.jpg
[14:44:05] <CaptHindsight> it's not like using Mesa or PLC's
[14:45:11] <CaptHindsight> good pcb layout, ESD protection, etc were all considered overbuilding
[14:45:27] <CaptHindsight> and have no place in their designs
[14:45:59] <Tom_L> they're a dime a dozen anymore
[14:46:27] <t12> have some engravings: http://www.thisiscolossal.com/2013/12/hobo-nickels-paolo-curcio/
[14:47:35] <CaptHindsight> and the Chinaco knockoffs are made even worse
[14:50:05] <Tom_L> are they not all made there??
[14:54:01] <CaptHindsight> oh, the ones made by Arduino have special powers
[14:54:51] <MacGalempsy> magical huh?
[14:55:42] <CaptHindsight> magic, voodoo, juju, B.S. whatever you want to call it
[14:56:35] <CaptHindsight> I like the ones made by Keystudio since they use yellow connectors
[14:57:01] <Jymmm> CaptHindsight: cause yellow connectors have super powers?
[14:57:21] <CaptHindsight> https://www.aliexpress.com/item/2014-the-last-new-MEGA-2560-R3-development-board-FOR-arduino-an-improved-version/32247818078.html
[14:57:34] <CaptHindsight> well super is a bit overblown
[14:58:43] <Jymmm> =)
[14:58:49] <Jymmm> just askin ;)
[14:59:03] <Tom_L> Jymmm, sportin a swimsuit yet?
[14:59:37] <CaptHindsight> indoor rafting?
[15:01:59] <MacGalempsy> any pics of the newdpaper heater?
[15:26:42] <JT-Shop> finally got that damn ladder done and tested for the dip tank
[15:27:34] <MacGalempsy> whats the dip tank for?
[15:29:44] <JT-Shop> they dip the boards in something that keeps fungus from growing for a few weeks so they have time to stack them with slats so they air dry
[15:30:40] <MacGalempsy> mesa boards?
[15:31:25] <JT-Shop> oak and hickory
[15:31:30] <MacGalempsy> oh. lol
[15:31:32] <JT-Shop> flooring
[15:32:26] <MacGalempsy> is there a mesa board like a 7i77 that is ethernet controlled?
[15:34:03] <MacGalempsy> something compact to control something like https://youtu.be/tW0PxUzTRT8
[15:34:17] <JT-Shop> 7i77E
[15:34:48] <JT-Shop> http://mesaus.com/index.php?route=product/product&path=66&product_id=66
[15:36:56] <CaptHindsight> so Mesa has Ethernet with Step Dir on the same board now
[15:38:16] <JT-Shop> aye
[15:39:04] <CaptHindsight> I see a 7i76E is there a servo version 7i77E?
[15:39:36] <JT-Shop> 7i92M or H + 7i77
[15:40:36] <CaptHindsight> so no all on one board yet, it is still two separate boards
[15:45:01] <suavesteve> A quick question, does anyone know if it's possible to modify a single axis feed-override? I'm retrofitting a machine which had a seperate Z override for canned cycles, which the owner really wants to keep in the replacement. Even if it wasn't limited to canned cycles, he'd be happy.
[15:45:03] <MacGalempsy> for an injection machine steppers would probably be fine.
[15:45:40] <Tom_L> suavesteve you'd have to separate the soft control in axis
[15:45:51] <Tom_L> someone was trying to do that some time back here
[15:45:57] <Tom_L> forget who it was
[15:47:07] <Tom_L> i'm not sure it works in canned cycles
[15:47:30] <suavesteve> I figured it wouldn't be an often-requested feature
[15:47:45] <suavesteve> Just thought I'd see if there was a quick out-of-the-box solution
[16:01:25] <R2E4> For the new JA stuff, what is the comment about requiring appropriate independant control logic for both joint and telop jogging?
[16:02:22] <R2E4> thats just for both joint and world, but if your not using joggin in joint you wont need it?
[16:05:04] <nubcake> hi
[16:13:50] <MacGalempsy> hi
[16:45:55] <gregcnc> zeeshan, I may end up making those an adapters. The connections on the compressor are flat face it turns out. Can't find drawings for AN spec though.
[16:46:29] <BeachBumPete> well I managed to get the coolant troughs and chip pans installed under the Cinci but not before I realized one of the custom mounts I made for the moving of the electronics cabinet impeded on the area that the coolant trough occupies a bit. I had to remove the bracket and cut it down some and then reinstall it so everything will fit properly. I also managed to bust my forehead on one of the leveling screw pads so I bled f
[16:47:08] <gregcnc> sounds like a long day
[16:47:40] <MacGalempsy> ouch. pics of head or it didnt happen
[16:48:32] <BeachBumPete> you want to see pics of my busted head?
[16:48:47] <MacGalempsy> lol. how much blood?
[16:48:55] <gregcnc> nothing is real without evidence today
[16:49:02] <BeachBumPete> what are you a vampire or somethin'
[16:49:16] <BeachBumPete> you guys will just have to take my word on it ;)
[16:49:18] <MacGalempsy> nah. just messin
[16:49:42] <BeachBumPete> I am VERY glad that the damn coolant troughs are under the machine tho they take up tons of room in the shop
[16:50:11] <MacGalempsy> what else is there left to do
[16:50:13] <BeachBumPete> there are the two trays and the big huge rubber hose that connects the left side to the right side, plus the chip pans that go over both of the troughs
[16:51:15] <BeachBumPete> well now that it is leveled and the trays are under it I can work on reconnecting the wiring that went from the back electronics cabinet to the pendant up front. About a dozen wires or so, then I will kinda go thru everything to ensure nothing vibrated loose during the transport
[16:51:56] <BeachBumPete> I still have to make some modifications to the cable chain setup to allow for the longer distance to the electronics cabinet. the lowering required moving it to the right side about six or seven inches
[16:52:22] <XXCoder> JT-i3: scaling part has what issue?
[16:52:23] <MacGalempsy> will u need to splice wires?
[16:52:45] <BeachBumPete> should not be a big deal as there was ample cable length and the cable chain even with the head all the way down goes quite a ways above the column
[16:52:52] <Tom_L> BeachBumPete how fitting just before halloween
[16:52:52] <BeachBumPete> no no splicing or cutting anything
[16:53:06] <BeachBumPete> Tom_L?
[16:53:12] <Tom_L> hole in head
[16:53:14] <MacGalempsy> cool when does the electrician come?
[16:53:24] <BeachBumPete> you mean I can carve pumpins on the VMC?
[16:53:35] <BeachBumPete> what electrician?
[16:53:42] <BeachBumPete> just kidding
[16:53:45] <MacGalempsy> the bloody forehead?
[16:53:58] <BeachBumPete> its not pretty
[16:54:15] <MacGalempsy> dont u have to run a new line for the vmc?
[16:54:17] <BeachBumPete> I may hire my friend to hook up to the mains for the sub panel he is a cert
[16:54:41] <BeachBumPete> no new anything but the sub panel really
[16:54:50] <BeachBumPete> the machine sits RIGHT next to the breaker panel
[16:54:58] <BeachBumPete> its like three feet away or so
[16:55:00] <gregcnc> that's convenient
[16:55:05] <MacGalempsy> do you have a panel switch- or do u have to pull the meter?
[16:55:29] <BeachBumPete> if I want to kill power completely I would have to pull the meter but not sure that will be necessary
[16:55:40] <Tom_L> oh heck, wire it hot
[16:55:52] <MacGalempsy> just standby for the next power outage
[16:56:02] <gregcnc> is there not a main breaker?
[16:56:19] <BeachBumPete> yeah there is a main breaker which will obviously be off
[16:56:49] <BeachBumPete> but the problem as I said earlier is that the mains go around the cabinet and into the top of the box so they are hot unless you pull the meter.
[16:57:22] <BeachBumPete> http://i.imgur.com/wDo8B6K.jpg
[16:58:27] <Tom_L> acceptable but not what i or probably you would have done
[16:58:28] <BeachBumPete> the plan is to pull that second 220 breaker down on the left side and install the larger sub panel feed breaker
[16:58:36] <BeachBumPete> what is?
[16:58:43] <Tom_L> the route of the mains
[16:58:59] <BeachBumPete> yeah its kinda stupid I think but probably the way they wired this particular box I guess
[16:59:20] <BeachBumPete> how would you do this tom?
[16:59:29] <Tom_L> which?
[16:59:40] <BeachBumPete> wiring this sub panel from that panel?
[16:59:49] <Tom_L> any spare room?
[16:59:52] <gregcnc> no open slots is tough
[17:00:16] <BeachBumPete> the only place that can be used like I said is that second breaker down on the left side
[17:00:16] <Tom_L> i found some narrow breakers for mine for a couple circuits which gave me room for a larger breaker
[17:00:36] <gregcnc> is it not in use, there is a lot of 220 stuff
[17:00:39] <BeachBumPete> I have a square D 100 amp
[17:00:41] <Tom_L> i made sure it used both buss bars too
[17:01:15] <Tom_L> the wide ones probably do
[17:01:16] <BeachBumPete> no that particular breaker used to power a well pump
[17:01:25] <gregcnc> perfect
[17:01:37] <Tom_L> does each leg come from a separate bar?
[17:01:47] <Tom_L> it would have to to be 220v
[17:01:57] <BeachBumPete> there is no well pump anymore so I will remove the breaker and install the new one there
[17:02:15] <BeachBumPete> not sure on the bar thing...
[17:02:22] <Tom_L> pull it and see
[17:02:26] <BeachBumPete> its a 220v 30 amp on there now
[17:02:33] <Tom_L> has to be then
[17:02:40] <BeachBumPete> standard square D breakers
[17:02:43] <gregcnc> I think that depends on the type of box
[17:02:56] <BeachBumPete> the one above it is the 50 amp range one
[17:03:33] <gregcnc> it's a full size 2 pole breaker so just put in what you need
[17:03:35] <BeachBumPete> actually its a 20 amp 220 volt one
[17:04:32] <gregcnc> I'd do that myself. nothing to it
[17:04:43] <BeachBumPete> but I am going to pull it out and install the larger one and then hopefully knockout an access hole in the side of the box and run the wires over to the sub panel which I plan to sit right next to it
[17:04:56] <BeachBumPete> I kinda agree
[17:05:08] <BeachBumPete> just leery of those bigass leads underneath everything
[17:05:20] <Tom_L> why?
[17:05:25] <BeachBumPete> really the breakers are ABOVE that
[17:05:29] <gregcnc> just jam a poky thing through them
[17:05:33] <BeachBumPete> just because they are mains
[17:05:35] <gregcnc> just DON"T
[17:05:37] <Jymmm> LICK EM
[17:05:45] <BeachBumPete> you guys are all heart
[17:05:58] <Tom_L> i'm not afraid to work in a box like that
[17:06:03] <Tom_L> just use precautions
[17:06:22] <Jymmm> BeachBumPete: Sounds like you are doing what I did, but just pull the meter if you have an issue
[17:06:24] <BeachBumPete> I think I can just kill the main breaker and remove the other one and stick the new one in and CAREFULLY hook up the new wires
[17:06:32] <Tom_L> you can probably attach the wired before you plug the breaker in anyway
[17:06:47] <Tom_L> ^^
[17:06:47] <BeachBumPete> thats true as well
[17:06:52] <XXCoder> so theres no "upstream" breaker
[17:07:02] <Tom_L> that's probably what i would do
[17:07:07] <BeachBumPete> no just the main you can see in the pic
[17:07:21] <gregcnc> yes, I've wired the breaker before installation
[17:07:23] <Tom_L> just bend everything so it fits right
[17:07:32] <BeachBumPete> yes definitely
[17:07:41] <BeachBumPete> the new wires are THICK so that might help a bunch
[17:08:04] <Tom_L> you could even loop it down a bit just to be save in case you ever had to move it
[17:08:11] <Tom_L> safe*
[17:08:15] <BeachBumPete> I bought a square D 100 amp sub panel at lowes and the ground bar for it as well as a 60 amp and a 40 amp
[17:08:58] <Tom_L> it'll be fine, don't worry about it
[17:09:18] <BeachBumPete> as long as I am carful it will be
[17:09:18] <gregcnc> 2AWG?
[17:09:28] <BeachBumPete> I think its 4
[17:09:49] <BeachBumPete> gotta check
[17:09:53] <gregcnc> 4 may be undersize for a 100A breaker
[17:09:56] <Tom_L> you got room for the neutral wire on the neutral bar?
[17:10:48] <BeachBumPete> I know the ones that went from the 60 amp breaker about 25 feet to the machine were adequate. If I need to get heavier to go from the box to the sub so be it.
[17:12:19] <BeachBumPete> http://i.imgur.com/8pBicip.jpg OUCH!
[17:12:24] <Tom_L> you might have an issue getting the neutral in
[17:12:44] <BeachBumPete> why?
[17:12:55] <Tom_L> is there an open screw for it?
[17:13:07] <Tom_L> that's gonna be a big wire
[17:13:39] <BeachBumPete> this is true
[17:13:52] <Tom_L> i don't see any open screws
[17:14:33] <BeachBumPete> well once I remove that one breaker there should be no?
[17:14:37] <Tom_L> looks like some are bigger than others too
[17:14:52] <BeachBumPete> sure
[17:14:55] <Tom_L> yeah if the hole is big enough
[17:14:58] <BeachBumPete> I will have to look at it
[17:15:08] <Jymmm> CaptHindsight: Does this have super powers? https://www.aliexpress.com/item/Mega-2560-R3-Mega2560-REV3-ATmega2560-16AU-CH340G-Board-ON-USB-Cable-compatible-for-arduino-No/32563483538.html
[17:15:17] <Tom_L> you could double up on another circuit there but i doubt that's code
[17:16:14] <BeachBumPete> I guess if I have to pay an electrician so be it.
[17:16:29] <Tom_L> that buss isn't hot
[17:16:43] <BeachBumPete> the ground buss?
[17:16:51] <Tom_L> yeah, i'd move a wire over if i had to
[17:17:15] <BeachBumPete> yeah I know its not hot but like I said the less I have to poke around in there the better.
[17:17:24] <Tom_L> i can't tell if 8 from the bottom is open or not
[17:17:31] <BeachBumPete> once I kill the main most of that area is fine
[17:17:32] <Tom_L> it's kinda hidden
[17:17:56] <BeachBumPete> yeah 8,9,10 even
[17:18:12] <BeachBumPete> what gauge ground wire would I need do you think?
[17:18:23] <Jymmm> BeachBumPete: 0/4
[17:18:28] <Tom_L> 8 & 10 are bigger screws it appears
[17:18:32] <Tom_L> use one of them
[17:18:41] <BeachBumPete> yeah I agree but 4 is pretty thick
[17:18:49] <Tom_L> you can tuck that wire under the rest pretty easy
[17:19:10] <Tom_L> just prebend it a bit
[17:19:41] <Tom_L> leave it plenty long and wrap around the bottom of the box
[17:19:46] <Tom_L> more room there
[17:19:51] <BeachBumPete> I mean all of those wires electrically go to ground so if I HAD To double one up is that not the same thing? I hope I will not have to and there are open terminals.
[17:20:10] <Tom_L> it won't hurt anything
[17:20:32] <BeachBumPete> as long as they all have good contact and are secured.
[17:20:37] <Tom_L> yup
[17:20:57] <BeachBumPete> sure wish the original box was better for me but oh well.
[17:23:09] <BeachBumPete> its interesting that in the entire time I was running the VMC on a 60 amp breaker in Tennessee it never once blew the breaker even when I crashed the hell out of it running a 3/4 cutter full width full depth thru a 1" bar of 6061.. it just slowed down and kept chugging... I wonder just how much it typically pulls actually.
[17:24:21] <BeachBumPete> I must say that I had to clean my shorts after that episode however :)
[17:26:04] <CaptHindsight> Jymmm: does it pass the juju test?
[17:26:13] <Tom_L> i'm not running heavy machines but iirc i used a 60A to the garage on mine
[17:26:25] <Tom_L> welder, compressor etc all fine
[17:26:36] <BeachBumPete> one at a time correct
[17:26:45] <Tom_L> i never worried about it
[17:26:51] <Tom_L> 5hp compressor
[17:28:12] <BeachBumPete> yeah like I said MOST of the time I run my machine quite gingerly
[17:28:26] <CaptHindsight> Jymmm: I think not. It's made and sold by ChinaCo. It's only good it it comes from Arduino but it may still be manufactured in China.
[17:28:27] <BeachBumPete> lightish cuts in predominatley aluminum parts
[17:29:04] <Tom_L> you still gonna make gun parts?
[17:29:17] <BeachBumPete> airgun parts?
[17:29:24] <Tom_L> yeah
[17:29:29] <BeachBumPete> of course ;)
[17:29:29] <Tom_L> the stuff you were making
[17:29:38] <BeachBumPete> can't wait to start making them again
[17:29:52] <BeachBumPete> got a bunch of customers waiting kindly for me to get up and running
[17:30:15] <CaptHindsight> Jymmm: notice the fine print? It says compatible and not 100% compatible.
[17:30:19] <BeachBumPete> if I can get the CNC lathe going as well I have a bunch of other parts to make on it.
[17:30:50] <Tom_L> you may not wanna run them both at the same time though
[17:30:59] <BeachBumPete> no I doubt I could
[17:31:18] <Tom_L> you get busy enough you could run bigger service
[17:31:21] <BeachBumPete> the CNC lathe has a 7.5 HP motor
[17:31:24] <Tom_L> or split it into 2
[17:32:12] <BeachBumPete> I probably should have just gone with a 5hp lathe spindle motor just for power consumption
[17:35:52] <BeachBumPete> I just figured bigger is better even tho the original machine came standard with the 5hp motor and the 7.5 HP motor was an upgrade..
[17:41:54] <BeachBumPete> I SO MISS having a lathe man
[17:42:23] <Nick-Shop> Whats the maximum voltage I can apply to a stepper motor rated at 4.8v per phase 3.0 amp , 2 phase , 425 oz in?
[17:42:33] <CaptHindsight> BeachBumPete: is there much work down there for a machinist?
[17:43:37] <malcom2073_> Nick-Shop: Afaik, it comes down to the dielectric strength of the windings, which is typically higher than you'd want to put through it
[17:43:45] <BeachBumPete> CaptHindsight don't know yet I have not gone looking too much since I have not gotten the machines operational yet
[17:44:17] <BeachBumPete> but I do have a lot of work waiting for me just from previous customers and some race car guys around here
[17:45:54] <Nick-Shop> <malcom2073> How would one get that rating?
[17:46:04] <malcom2073_> Nick-Shop: Datasheet, otherwise the mfg
[17:46:44] <Deejay> gn8
[17:47:00] <Nick-Shop> I guess I'll try the mfg - bet they don't know
[17:48:10] <CaptHindsight> https://e2e.ti.com/blogs_/b/motordrivecontrol/archive/2012/01/17/the-5-2v-stepper-motor-and-50v-stepper-driver-paradox
[17:49:56] <malcom2073_> Like I said, typically higher heh
[17:50:12] <malcom2073_> I mean, I'm sure at 1kv+ you'll cause damage of some sort, even if it's for such a small fraction of a second that it doesn't overheat
[17:50:23] <malcom2073_> But do they even make stepper drivers at those voltages? :-P
[17:55:46] <Nick-Shop> want to try out a DIV268N with a 48v power supply and not fill the shop with smoke Motor is a 23HS9430B
[17:56:20] <Nick-Shop> the driver says 48v is ok - max
[17:56:55] <Tom_L> i wouldn't run a driver at it's max voltage
[17:57:08] <Tom_L> especially if it came from china
[17:57:27] <CaptHindsight> Nick-Shop: so you want to know the maximum voltage into the driver not the max voltage across the motor
[17:58:32] <CaptHindsight> you hope it whats written on the enclosure or the spec sheet
[17:59:12] <CaptHindsight> but if it's a knock-off from China then anything goes
[17:59:35] <Nick-Shop> specs for diver 1s 12-48v - I assume thats what it will send out to the motor at max of 3 amps
[17:59:50] <CaptHindsight> nope
[18:00:01] <CaptHindsight> it chops the voltage
[18:00:34] <Nick-Shop> chops it to what?
[18:01:26] <Tom_L> current
[18:01:38] <CaptHindsight> http://www.haydonkerk.com/Resources/StepperMotorTheory/tabid/192/Default.aspx
[18:01:45] <Tom_L> the higher voltage helps it recover quicker
[18:01:54] <Tom_L> so you get better performance
[18:02:18] <Nick-Shop> want to get to the upper part of the 425 oz-in torque
[18:04:24] <Tom_L> what's the current rating on the steppers?
[18:04:24] <CaptHindsight> https://ece.uwaterloo.ca/~mte320/Files/Stepper%20Motor.pdf
[18:07:37] <Nick-Shop> current rating is 3.0 amps
[18:08:05] <Tom_L> what about the driver?
[18:08:53] <Nick-Shop> Between 2 links - have a weeks worth of reading :-)
[18:09:29] <Nick-Shop> diver is settable to 5amps
[18:10:02] <Nick-Shop> 3.3 amps is the closest to what I need
[18:11:24] <Frank_10> hi
[18:11:25] <Frank_10> bye
[18:13:07] <XXCoder> https://www.youtube.com/watch?v=ioOivnmlRUI
[18:13:08] <XXCoder> man
[18:13:10] <XXCoder> that is awesome
[18:13:15] <XXCoder> look how he balanced it!!!
[18:49:35] <zeeshan> that is a neat project XXCoder
[18:49:46] <XXCoder> indeed
[20:04:40] <gregcnc> RC guys been balancing props like that for 30 years
[20:07:47] <zeeshan> whats that method called?
[20:08:11] <zeeshan> magneti c balancing?
[20:11:58] <gregcnc> magnetic balancer, effective for light pieces that can be slipped over a shaft or I guess integral shaft with a pointed end
[20:12:52] <zeeshan> ah
[20:14:27] <gregcnc> been googling for AN specs, but can't seem to find full details
[20:14:34] <SpeedEvil> A quad can in principle report dynamic balance
[20:14:36] <zeeshan> i have it
[20:14:40] <zeeshan> what fitting y9ou lookign for
[20:14:43] <zeeshan> i got a cad model too if you wantr
[20:14:56] <SpeedEvil> - correlation of the accelleration with rotation for a motor
[20:15:05] <SpeedEvil> (if the ESC is sufficiently controllable)
[20:15:39] <gregcnc> but do effectively adjust the balance you needs software to interpret the measurements
[20:15:41] <SpeedEvil> (most aren't, and sensory)
[20:17:07] <gregcnc> -6
[20:17:20] <zeeshan> damn it i got -10 -8 -16
[20:17:21] <zeeshan> lol
[20:17:59] <gregcnc> eh I'll just measure what I have
[20:18:13] <zeeshan> you can download the models from parker's site
[20:18:21] <zeeshan> as long as it's 37 degree
[20:18:28] <zeeshan> and you get the distance from the taper to the thread correct
[20:18:30] <zeeshan> youre good to go :P
[20:18:35] <gregcnc> I did see that
[20:18:55] <zeeshan> i was tired of paying 10 bux an aluminum weld bung
[20:19:02] <zeeshan> so i made about 100 of each of the above
[20:19:06] <zeeshan> now i have a life time supply
[20:19:06] <zeeshan> :D
[20:21:59] <gregcnc> I'm not even sure I can buy an adapter to fit the compressor
[20:21:59] <zeeshan> greg
[20:22:05] <zeeshan> you has dropbox?
[20:22:11] <gregcnc> no
[20:22:20] <zeeshan> hm
[20:22:22] <zeeshan> how to send pdf
[20:22:28] <zeeshan> actually i think i can share link
[20:22:29] <zeeshan> sec
[20:23:42] <zeeshan> https://www.dropbox.com/s/f9jyg665bd6wnja/AS4395%20Standard%20%28superceded%20MIL-F-5509%28.pdf?dl=0
[20:23:43] <zeeshan> try that
[20:24:46] <gregcnc> great! thanks
[20:24:57] <zeeshan> np!
[20:26:22] <zeeshan> http://imgur.com/a/8Dbxt
[20:26:24] <zeeshan> i dont get my lathe
[20:26:28] <zeeshan> starting to work on it
[20:26:38] <zeeshan> it looks like they use a 1:1 spur gear?
[20:26:47] <zeeshan> isn't that asking for backlash?
[20:27:54] <gregcnc> belts have backlash too
[20:28:20] <gregcnc> maybe motor was int he way
[20:28:49] <zeeshan> at20 is supposed to be backlash free
[20:29:13] <zeeshan> nahh man
[20:29:19] <zeeshan> they have it like this for X axis too
[20:29:39] <zeeshan> (i made a typo in album title), this is the Z servo
[20:30:52] <zeeshan> you think they've machine the spur gears very precisely
[20:30:59] <zeeshan> so theres less than a couple tenths backlash?
[20:30:59] <zeeshan> ;p
[20:31:33] <gregcnc> could be
[20:32:36] <gregcnc> what kind of position feedback does the machine have?
[20:32:50] <zeeshan> so far i've only seen encoders on the motors
[20:41:42] <gregcnc> is that a taperlock on that gear?
[20:42:11] <zeeshan> honestly i've never seen it before i s tarted work at my current company
[20:42:25] <zeeshan> it looks like a tsubaki powerlock to tme
[20:42:27] <zeeshan> *to me
[20:42:42] <zeeshan> so yes, taper lock
[20:42:45] <Tom_L> zeeshan what you gettin done?
[20:42:57] <zeeshan> Tom_L: going through the machine slowly
[20:43:10] <zeeshan> i took off the z servo motor today and starting to clean things
[20:43:21] <zeeshan> realized that it's coupling to the z ball screw w/ a spur gear
[20:43:29] <zeeshan> so i was thinking "how do these guys take care of backlash"
[20:44:58] <Tom_L> you finding books for it anywhere?
[20:45:12] <zeeshan> nope
[20:45:14] <zeeshan> :(*
[20:45:26] <zeeshan> i have a book for the motors
[20:45:27] <gregcnc> which model is that?
[20:45:42] <zeeshan> but i dont have books for the machine. the motors don't normally come with these gears
[20:45:46] <zeeshan> gregcnc: model of the motor?
[20:45:51] <gregcnc> lathe
[20:45:56] <zeeshan> nakamura tome tmc-3
[20:46:01] <zeeshan> w/ fanuc 3t control
[20:50:58] <zeeshan> i wish i had a parts catalog for this machine
[20:51:02] <zeeshan> cause it'd at least show the exploded views.
[20:52:25] <Tom_L> is the SC series anything close?
[20:52:42] <sync> I think you can get really low backlash on spur gears zeeshan
[20:52:51] <sync> they just have to be made right
[20:52:58] <zeeshan> Tom_L: i'm not sure
[20:53:02] <zeeshan> they look similar :P
[20:53:04] <zeeshan> sync: hm
[20:53:11] <zeeshan> i guess i'll find out when the machine is running!
[20:53:19] <Tom_L> http://www.methodsmachine.com/_assets/machines/b7754b0d-8a0a-45e7-b709-4fd543e652e3.pdf
[20:53:26] <Tom_L> i just pulled that up is why i asked
[20:53:43] <zeeshan> i see red cap motors :P
[20:53:46] <zeeshan> so thats already diff!
[20:55:03] <gregcnc> direct drive servos
[20:55:42] <zeeshan> yup youre right
[20:56:09] <zeeshan> worse comes to worse, if i do find out it's got serious backlash
[20:56:15] <zeeshan> ill convert to at20 belts or something
[20:56:37] <Tom_L> http://www.ironfurnacecwma.org/nakamura/nakamura-tome-tmc-3-manual.pdf
[20:56:39] <Tom_L> zee
[20:56:42] <gregcnc> do the gears look worn?
[20:56:57] <zeeshan> no
[20:57:07] <zeeshan> Tom_L: thats some crazy pdf
[20:57:11] <zeeshan> with random words
[20:57:11] <zeeshan> lol
[20:57:36] <gregcnc> those links are always BS, there are so many of than that make google results useless
[20:57:45] <zeeshan> why do they exist
[20:57:47] <zeeshan> i dont get it
[20:57:47] <zeeshan> lol
[20:57:53] <zeeshan> i come across those pos's sometimes
[20:57:55] <gregcnc> click traffic i assume
[20:58:37] <gregcnc> eventually they lead you to a site where they want you to register to download, but i never tried
[20:58:52] <zeeshan> sounds like a scam
[20:58:52] <zeeshan> :P
[20:59:02] <gregcnc> some here was looking for a manual too .....http://www.cnczone.com/forums/machinery-manuals-brochures/286078-nakamura-tome-tmc-3-wiring-hydraulics-manual.html
[20:59:21] <gregcnc> some turbozee guy
[20:59:36] <gregcnc> lol
[21:00:57] <zeeshan> haha
[21:01:00] <zeeshan> i posted that so long ago dude
[21:01:04] <zeeshan> i'm hopeless!
[21:01:06] <Tom_L> hah
[21:01:10] <Tom_L> just saw that too
[21:01:18] <zeeshan> i tried emailing methodsmachine
[21:01:27] <zeeshan> they told me they onyl deal with usa people
[21:01:28] <zeeshan> ;[
[21:01:43] <zeeshan> i contacted my local nakamura supplier
[21:01:54] <zeeshan> they told me they could likely get the manuals, they dont know for sure
[21:02:00] <zeeshan> but it'll prolly cost me 1000-2000$
[21:02:06] <gregcnc> https://www.amazon.com/gp/offer-listing/B012YC65BE/ref=dp_olp_used_mbc?ie=UTF8&condition=used
[21:02:08] <zeeshan> (basically they were telling me to fuckoff)
[21:02:46] <zeeshan> i contacted arpi too
[21:02:50] <zeeshan> they dont have it anymore
[21:02:53] <zeeshan> old listing
[21:03:08] <zeeshan> i wish someone in here was japanese
[21:03:18] <zeeshan> i guarantee you that it exists on a jap site
[21:03:43] <Tom_L> what's google do with it?
[21:05:09] <Tom_L> is a tmc15 similar?
[21:05:22] <zeeshan> no
[21:05:23] <zeeshan> its tiny

[21:06:04] <Tom_L> what about slant 4?
[21:06:11] <gregcnc> how old is that lathe?
[21:06:17] <zeeshan> 1983 i thjink
[21:07:06] <zeeshan> Hello, I have come across a machine to repair. Could you please tell me where I can get a wiring manual for: Nakamura Tome TMC-3 Serial #15419 I would need an english version. I would appreciate any help. Best Regards, Zeeshan
[21:07:14] <dioz> any suggestions on a little 1/3 HP metal lathe?
[21:07:14] <zeeshan> Hi Jeff san TMC-3 15419 was sold to CANADA according to NT data base. I think this inquiry from person in CANADA. Please take care of this issue. Thanks and Best regards Nakamura-Tome Precision Industry Co., LTD
[21:07:38] <zeeshan> Please find as follows price and delivery for requested manual for your Nakamura TMC-3, S/N 15419. TMC-3 Parts List …. Price CDN $350.00
[21:07:44] <zeeshan> oh its 350 cad for the parts manual
[21:07:45] <zeeshan> hmm
[21:08:04] <zeeshan> and another 350 for electrical wiring diagrams
[21:08:11] <zeeshan> i might have to just shell that out
[21:08:15] <zeeshan> =[
[21:08:16] <Tom_L> where's that at?
[21:08:23] <zeeshan> im going through my emails from last year
[21:08:27] <Tom_L> oh
[21:08:51] <zeeshan> elivery ex stock after receipt of your order and remittance.
[21:08:55] <zeeshan> wtf kind of delivery terms is that
[21:08:56] <zeeshan> lol
[21:09:20] <Tom_L> take your money and sorry sucker
[21:09:33] <gregcnc> means they have it in stock
[21:10:18] <Tom_L> hah did you see google's logo for halloween
[21:10:29] <zeeshan> http://phoenix.craigslist.org/evl/tls/5793150595.html
[21:10:33] <zeeshan> i found this ad on craigslist
[21:10:40] <zeeshan> was posted a month ago
[21:10:52] <zeeshan> maybe he'll sell me the manuals? :P
[21:11:48] <zeeshan> ah fak he has fanuc 6t on his machine
[21:12:12] <Tom_L> worth asking
[21:14:35] <Tom_L> https://www.amazon.com/NAKAMURA-LATHE-PARTS-CATALOG-MANUAL/dp/B012YC65BE
[21:14:38] <Tom_L> zee
[21:15:19] <zeeshan> that is sold by arpi
[21:15:25] <zeeshan> they dont have it anymore
[21:16:31] <dioz> any suggestions on a little 1/3 HP metal lathe?
[21:17:17] <dioz> any suggestions on a tig welder ac/dc with pedal to weld some 16-28 gauge sheet metal?
[21:17:20] <dioz> galv iron
[21:17:21] <gregcnc> are you trying to bring the fanuc back to life?
[21:18:33] <zeeshan> hell no!
[21:18:37] <zeeshan> im only reusing the drives
[21:18:55] <zeeshan> i mostly want the parts manual to figure out why there is so many hydraulics
[21:18:59] <zeeshan> and figure out all the switches
[21:19:07] <zeeshan> so i can make sure i understand the logic required
[21:19:12] <dioz> hydrauliks
[21:19:16] <Tom_L> wonder if the local machine tool place could help you
[21:19:19] <zeeshan> for example, i don't understand what happens when you try to order a tool change
[21:19:21] <Tom_L> maruka usa
[21:19:28] <zeeshan> and if there is a brake for the X axis?
[21:19:34] <zeeshan> or some sort of lock
[21:19:41] <zeeshan> i dont see a brake on the motor itself
[21:19:56] <gregcnc> is the original control dead?
[21:23:31] <zeeshan> not sure
[21:23:36] <zeeshan> but it's too ancient for me
[21:23:37] <zeeshan> :P
[21:23:41] <zeeshan> i need to linuxcnc it!
[21:29:58] <dioz> anyone here know how to make a overhead projector ?
[21:32:12] <dioz> anyone here ever used an overhead projector to put an image on a wall in a childs bedroom?
[21:32:23] <dioz> gf wants to do some finding nemo stuff for a child
[21:32:43] <XXCoder> zeeshan: buy machine and manuals, keep manuals and sell machine for little bit more
[21:32:51] <zeeshan> hehe
[21:33:27] <XXCoder> or do minor refab and make it linuxcnc machine and sell for $2k more
[21:33:57] <Tom_L> archivist doesn't have anything like that does he?
[21:34:00] <BeachBumPete> we used an overhead projector to paint scenes from the hobbit back in school
[21:34:02] <zeeshan> im not planning to sell it
[21:34:10] <zeeshan> this is going to be my machine for a lpong time :)
[21:34:12] <Tom_L> zeeshan ^^
[21:34:17] <Tom_L> have you checked with him
[21:34:22] <zeeshan> Tom_L: i asked him a while back
[21:34:23] <XXCoder> oh thought you was considering buying second one for manuals lol
[21:34:25] <zeeshan> nothin
[21:34:33] <zeeshan> XXCoder: nahh
[21:34:42] <zeeshan> im trying to avoid shelling at 1k iin manuals
[21:34:45] <zeeshan> i could use that money for vfd.
[21:34:47] <zeeshan> :[
[21:34:50] <Tom_L> what makes you think you can get them in japanese?
[21:35:04] <zeeshan> cause theyre made in japan
[21:35:07] <zeeshan> im sure they sell em locally
[21:35:10] <zeeshan> and more locals buy it!
[21:35:10] <XXCoder> zeeshan: mind doing a little consulting free? heh
[21:35:23] <zeeshan> sup
[21:35:47] <XXCoder> I has BOB breakout, and I want spindle that knows what rpm its running at, and I want to use 500v ch9nese spindle
[21:35:50] <XXCoder> 52mm type
[21:36:06] <XXCoder> possible?
[21:36:46] <Tom_L> powered by what?
[21:37:00] <XXCoder> usual psu
[21:37:02] <Tom_L> a vfd?
[21:37:05] <zeeshan> 500V?
[21:37:10] <zeeshan> that is some serious voltage
[21:37:12] <XXCoder> thats what I dont understand fully
[21:37:21] <XXCoder> oops thats typo
[21:37:23] <XXCoder> 500w lol
[21:37:39] <Tom_L> a vfd should be able to give you the rpm
[21:37:47] <zeeshan> is it an ac motor
[21:37:49] <zeeshan> or dc?
[21:37:55] <XXCoder> ze lemme link
[21:38:05] <zeeshan> Tom_L: buy me manuals
[21:38:05] <zeeshan> ;[
[21:38:10] <Tom_L> poo
[21:38:15] <Tom_L> i can't find any
[21:38:20] <XXCoder> https://www.amazon.com/Konmison-Spindle-Motor-Converter-Collect/dp/B0154LENB6 300w but same idea
[21:38:48] <zeeshan> its a dc spindle motor
[21:38:55] <Tom_L> water cooled is better
[21:39:08] <zeeshan> if you want to measure the rpm of that motor
[21:39:09] <XXCoder> yea but then mostly wood and little bit alum
[21:39:14] <zeeshan> you're going to need to put a spindle encoder on it
[21:39:19] <zeeshan> Tom_L: made spindle encoders
[21:39:53] <Tom_L> not that rpm
[21:40:05] <zeeshan> 12000 rpm psst
[21:40:07] <zeeshan> thats nothin
[21:40:08] <zeeshan> ;P
[21:40:15] <Tom_L> i know
[21:40:21] <Tom_L> but for a regular encoder?
[21:40:44] <zeeshan> just get a single line encoder
[21:40:45] <zeeshan> ;p
[21:40:45] <XXCoder> 3k-12k is ok I guess. I was thinking maybe optical encoder, trigger each rotation (not positonal, would enable tapping)
[21:40:58] <zeeshan> its not like youre going to be tapping with this thing
[21:40:59] <zeeshan> :)
[21:41:05] <XXCoder> indeed
[21:41:18] <XXCoder> so how would I wire it up
[21:41:52] <zeeshan> i'm not sure how you'd do it with just a bob
[21:42:06] <Tom_L> doesn't pete make some dc drivers?
[21:42:09] <XXCoder> that was what i was wondering
[21:42:27] <XXCoder> zee that one comes with VDF looks like
[21:42:36] <zeeshan> thats not a vfd
[21:42:41] <zeeshan> its a dc drive
[21:42:53] <XXCoder> " Spindle Motor+110V VFD+clamp+13* ER11 "
[21:43:14] <zeeshan> i guess variable frequenc ydrive
[21:43:18] <zeeshan> can refer to dc too
[21:43:23] <XXCoder> interesting
[21:43:24] <zeeshan> i'm used to seeing them for ac :)
[21:44:10] <Tom_L> https://www.amazon.com/dp/B0154MW4E8/ref=psdc_13400331_t1_B0154LENB6
[21:44:16] <Tom_L> is that the one you're looking at?
[21:44:25] <Tom_L> analog input
[21:44:56] <XXCoder> well one thing Im still uncertain is how control those type of spindle
[21:44:58] <Tom_L> doesn't say if it's 0 - +10v or +-10v
[21:45:09] <XXCoder> maybe some other hardware can control it better
[21:45:10] <Tom_L> mine is 0--10v
[21:45:19] <XXCoder> if I recall right, 0 to 10v
[21:45:29] <Tom_L> 7i47s would do
[21:45:44] <Tom_L> that's what i'm using for mine
[21:45:57] <Tom_L> but i had to use an isolator board
[21:46:05] <XXCoder> can I add some form of feedback, for rpm, and it sets and adjusts if it slows down while cutting
[21:46:39] <Tom_L> i put mine in a pid loop with an encoder
[21:46:52] <XXCoder> pid?
[21:47:20] <Tom_L> http://linuxcnc.org/docs/2.7/html/man/man9/pid.9.html
[21:48:21] <Tom_L> bleh... i'm getting nowhere faster than you tonight
[21:48:41] <XXCoder> interresting
[21:49:14] <XXCoder> only one I know of is super-pid
[22:00:29] <XXCoder> https://www.youtube.com/watch?v=MQrzcwsGYy8
[22:00:42] <XXCoder> man I like that guy in captain disillusion
[22:52:04] <Kevin`> XXCoder: you might want to go the other route.. leave the spindle open-loop and instead adjust everything else based on the measured spindle speed
[22:52:39] <XXCoder> make x, y z slow down if spindle slow down?
[22:52:58] <Kevin`> I expect that works better for threading, and if it really overloads it won't just keep pushing on
[22:53:31] <Kevin`> that's an induction-drive spindle right? it will maintain a pretty accurate speed by itself aside from load variation if so
[22:54:00] <Kevin`> oop, nevermind
[22:54:08] <Kevin`> I looked at the link and it's only two wires, so dc
[22:54:12] <XXCoder> hmm so basically basic dc vfd but has rpm sensor that helps x y z scale with real rpm?
[22:54:24] <Kevin`> on that you basically control power/torque, so you need to go closed loop to get anything close to a reasonable speed
[22:55:34] <Kevin`> the three wire spindles are nearly synchronous by themselves, and I mistakenly thought that's what you had
[22:56:04] <XXCoder> yea im still very vague on spindle control unfortunately. was previously using simple grinder lol
[23:17:34] <XXCoder> lol https://www.kickstarter.com/projects/1830738289/maslow-cnc-a-500-open-source-4-by-8-foot-cnc-machi?ref=category_recommended
[23:45:57] <Kevin`> I think you can do better for $500
[23:47:00] <CaptHindsight> mo'profit
[23:47:21] <Kevin`> I like the idea, but it probably doesn't work as a commercial product, doesn't compete with mass produced routers
[23:49:53] <CaptHindsight> I only want to contribute if he promises to take the money and build a shack in Saskatoon
