[02:37:50] <Deejay> hi XXCoder
[08:12:20] <Tom_itx> moin
[09:22:16] <zeeshan|2> mornin :P
[09:24:04] <archivist> mid afternoon, what time do you call this!
[09:24:55] <zeeshan|2> archivist: should i keep this level
[09:25:22] <archivist> hard fo rme to say :(
[09:25:34] <zeeshan|2> is there anyway i can put a 0.0005" vial in it?
[09:25:58] <archivist> or just read/estimate it to that accuracy
[09:26:09] <zeeshan|2> i wanted this for machine leveling
[09:26:19] <zeeshan|2> the manuals usually say "0.05/1m level to be used"
[09:26:44] <archivist> I have changed a vial in the clinometer, that cost me £80 just for the vial
[09:26:54] <zeeshan|2> thats not bad
[09:27:04] <zeeshan|2> where do you get vials from?
[09:27:27] <archivist> some place in Leicester
[09:28:57] * zeeshan|2 needs
[09:29:05] <zeeshan|2> no 130952 hilger watts vial
[09:31:16] <archivist> or one encased in 12" of Cooke Troughton Sims iron
[09:31:36] <zeeshan|2> archivist: please help me find a vial for it :)

[09:38:47] <zeeshan|2> http://www.ebay.co.uk/itm/Hilgaer-Watts-12-Engineers-Precision-Block-Spirit-Machine-Level-in-box-130328-/301839927974?hash=item46470fcaa6:g:urAAAOSwBLlVT32X
[09:38:49] <zeeshan|2> what do you think of this?

[09:39:56] <zeeshan|2> I need one 0.05/1m
[09:40:32] <zeeshan|2> i see couple on ebay
[09:40:35] <zeeshan|2> for like 125 quid
[09:40:38] <zeeshan|2> but they look a bit rough
[09:40:44] <zeeshan|2> http://www.ebay.co.uk/itm/Cooke-Troughton-Simms-Ltd-Engineers-Level-original-Box-Very-nice-/361473438702?hash=item54297ef3ee:g:xVAAAMXQM0FRfVXg
[09:40:54] <archivist> my spare is "used"
[09:41:02] <zeeshan|2> lets see! :D
[09:41:20] <archivist> let me take a pic.....
[09:51:54] <zeeshan|2> la la la
[09:55:15] <archivist> clear space.....
[09:57:45] <malcom2073> Man... spend $90 on a stupid vacuume hose kit for my car.. only to find it's missing the one piece that I bought the damn set for anyway.
[10:02:50] <archivist> zeeshan|2, the darker one http://www.collection.archivist.info/searchv13.php?searchstr=cooke+troughton+levels
[10:02:55] <archivist> last 5 images
[10:04:11] <archivist> had a bit of a hard life, has some wear on its feet
[10:06:02] <zeeshan|2> i dont see wear? :)
[10:06:10] <zeeshan|2> you mean the corners being rounded?
[10:06:36] <zeeshan|2> is there adjustment for the vial?
[10:09:49] <archivist> the vial adjustment is under the serial number label
[10:10:04] <zeeshan|2> i kinda like the design of the hilger watts
[10:10:08] <zeeshan|2> i dont know why!
[10:10:36] <archivist> I see wear when I slide it on the surface plate and get shiny patches
[10:10:53] <zeeshan|2> ah
[10:10:58] <zeeshan|2> http://www.collection.archivist.info/searchv13.php?searchstr=hilger+watts
[10:11:01] <zeeshan|2> im liking this page more :)
[10:13:30] <archivist> my box is only a .001
[10:13:38] <zeeshan|2> same as mine
[10:13:40] <zeeshan|2> 6.2
[10:14:37] <archivist> but cooke did some good stuff http://www.collection.archivist.info/searchv13.php?searchstr=PD9357
[10:14:58] <zeeshan|2> to me , a person who doesn't know much about levels
[10:15:08] <zeeshan|2> the hilger watts looks higher quality :P
[10:15:12] <zeeshan|2> "looks" being the keyword
[10:17:04] <archivist> the cooke box is .00025 " though :)
[10:18:47] <archivist> damn the UPS price for sending it is a bit yuck
[10:19:04] <zeeshan|2> how much?
[10:19:18] <zeeshan|2> uk to canada shipping is $$ :)
[10:19:41] <archivist> 107 for the cheapest to 137
[10:19:50] <zeeshan|2> wow!
[10:19:56] <zeeshan|2> that box level came to me for 35 quid
[10:20:08] <zeeshan|2> (70$ cad)
[10:20:21] <zeeshan|2> they used royal mail though i think
[10:20:25] <archivist> what carrier?
[10:20:26] <zeeshan|2> which get rerouted to canada post
[10:21:56] <zeeshan|2> if youre sending 2kg
[10:22:11] <zeeshan|2> using royal mail, using international standard
[10:22:14] <zeeshan|2> its 26 quid
[10:22:59] <archivist> but including packing this currently is around 10kg
[10:23:24] <PetefromTn_> Royal mail....Baah ;)
[10:23:45] <archivist> I kept the packing and it has a <10kg label
[10:26:06] <zeeshan|2> 10kg!!
[10:26:08] <zeeshan|2> jeez
[10:27:34] <archivist> actually it was 6.5 kg in packing
[10:29:44] <zeeshan|2> i dont they ship anything more than 2.5kg
[10:29:47] <zeeshan|2> =/
[10:31:57] <archivist> your level is somewhat heavy, my 6.2 is a gnats over 5kg
[10:32:07] <archivist> in box
[10:33:14] <archivist> he might have sent it on the new ebay global shipping thing
[10:33:19] <zeeshan|2> yes
[10:33:23] <zeeshan|2> that was it exactly
[10:34:21] <archivist> I had something via that route to here just before xmas
[10:34:35] <archivist> a bit of renishaw :)
[10:34:59] <zeeshan|2> hehe
[10:35:50] <archivist> amusing getting cheap renishaw from that distance
[10:36:27] <zeeshan|2> i have yet to find anything cheap renishaw :P
[10:36:46] <archivist> http://www.ebay.co.uk/itm/400683596800 17$ shipping
[10:37:14] <zeeshan|2> i dont know what that is :P
[10:37:18] <zeeshan|2> thats the prob with renishaw
[10:37:19] <zeeshan|2> theres so many models
[10:37:20] <archivist> just a socket for the LP2 probe
[10:37:24] <zeeshan|2> not sure which one i need for digitizing
[10:38:03] <archivist> yes lots of reading and learning to do
[10:38:47] <archivist> cant find docs to take the TP2 probe apart to clean the contacts
[10:41:26] <zeeshan|2> looks like omp40
[10:41:27] <zeeshan|2> is what i want
[10:41:59] <zeeshan|2> but i think it uses line of sight..
[10:42:03] <zeeshan|2> to transmit
[10:43:44] <PetefromTn_> https://knoxville.craigslist.org/tls/5421952218.html sweet welding table deal
[10:43:59] <zeeshan|2> that is cheap pete! :D
[10:44:06] <zeeshan|2> monster size table
[10:44:28] <PetefromTn_> hell yeah I bet that bitch is REALLY HEAVY!!
[10:44:46] <zeeshan|2> im not sure how youd get that off a trailer
[10:44:54] <zeeshan|2> pump truck when its on the ground
[10:44:57] <zeeshan|2> but forklift needed?
[10:44:59] <PetefromTn_> If I was not moving I would be calling that guy right now
[10:46:18] <archivist> rofl, builders level
[10:46:45] <zeeshan|2> lol archivist
[10:46:46] <Tom_itx> zeeshan|2 want's to make sure the barber got his flattop flat
[10:46:48] <PetefromTn_> well its not a granite surface plate man
[10:47:00] <zeeshan|2> its a joke
[10:47:04] <zeeshan|2> we're level nerds
[10:47:05] <zeeshan|2> :)
[10:47:50] <Tom_itx> so PetefromTn_ thinks he's movin again...
[10:48:01] <PetefromTn_> 3/4 plate is supposedly 30.6 lb/ft
[10:48:15] <PetefromTn_> Tom_itx Don't know yet man
[10:48:16] <zeeshan|2> isnt it 7/8
[10:48:38] <Roguish> steel ==== 0.283 lb / cubic inch
[10:48:38] <Tom_itx> anticipation killin ya?
[10:48:57] <PetefromTn_> looks like 3/4 to me but I may be blind LOL
[10:49:08] <PetefromTn_> hell yeah the anticipation is killing me man
[10:49:14] <PetefromTn_> rub it in why dontcha
[10:49:19] <PetefromTn_> ;)
[10:49:23] <zeeshan|2> my table which is a 5 x 3
[10:49:26] <zeeshan|2> 1/2"
[10:49:30] <zeeshan|2> just the top is 500lb
[10:49:43] <PetefromTn_> that is probably 900 lbs easy huh
[10:49:49] <zeeshan|2> more
[10:49:54] <zeeshan|2> cause its bigger
[10:49:58] <PetefromTn_> sure
[10:50:11] <Tom_itx> OT but anybody use the square reader for business?
[10:50:26] <zeeshan|2> 4032 cubic inches
[10:50:51] <zeeshan|2> 1141 lb :P
[10:50:52] <PetefromTn_> 4608?
[10:51:40] <zeeshan|2> 4*8*12^2*.875
[10:52:03] <PetefromTn_> .75 ;)
[10:52:11] <zeeshan|2> it says 7/8 in the ad
[10:52:47] <zeeshan|2> but i think youre right
[10:52:50] <PetefromTn_> I know it does... can't remember if 7/8 steel measures 3/4
[10:52:51] <zeeshan|2> hes got that written wrong
[10:52:57] <zeeshan|2> causehe's showing .75
[10:53:10] <PetefromTn_> still thick as hell and monster heavy
[10:53:33] <Tom_itx> PetefromTn_ what's it gonna cost ya to move all your machines to FL?
[10:53:45] <PetefromTn_> too damn much :D
[10:53:56] <Tom_itx> worth taking them?
[10:54:03] <Tom_itx> or get more once you're there..
[10:54:05] <PetefromTn_> probably $2k or more
[10:55:54] <PetefromTn_> so yeah way worth the price but it still sucks to have to pay it.
[10:56:17] <PetefromTn_> shame these things gotta be so damn heavy huh
[10:56:37] <Tom_itx> shove it in a Uhaul... haha
[10:56:49] <PetefromTn_> I would if it would fit ;)
[10:57:02] <PetefromTn_> bitch is pretty big
[10:57:14] <Tom_itx> i doubt they're trucks are rated for the load
[10:57:31] <PetefromTn_> I did not really realize HOW big until I saw it on the back of that rollback wrecker coming to my house
[10:59:56] <PetefromTn_> http://imgur.com/fvAsjnC
[11:01:22] <Tom_itx> i bet he had fun unloading that
[11:01:45] <PetefromTn_> http://imgur.com/UWaJBSO
[11:02:28] <PetefromTn_> honestly he made it look pretty damn easy....I was the one chewing my fingernails LOL
[11:03:31] <PetefromTn_> he actually used the secondary vehicle ram underneath the bed to drag it to the edge of the ramp and had it hanging off the back just enough to get the skids on the concrete
[11:04:59] <PetefromTn_> then he sorta tilted the bed a bit, released the winch a bit, shuttled the bed out from under it slowly, released the winch a bit, and kept jockeying it until most of it was on the concrete.. then he released the winch some more and pulled the truck completely out from underneath it while still controlling the top with the winch
[11:05:09] <PetefromTn_> once it was on the ground completely
[11:05:21] <PetefromTn_> he used that big ram to push the machine way back into the shop,
[11:05:31] <PetefromTn_> then he backed up some more and did it again
[11:05:44] <PetefromTn_> until it was basically where it sits now within a few feet
[11:06:01] <PetefromTn_> guy sure knew how to run that rollback
[11:06:30] <PetefromTn_> I am HOPING for a similar ease to taking it out and unloading it down in Florida
[11:06:43] <PetefromTn_> ASSUMING we pass these inspections and actually close on the house LOL
[11:06:45] <CaptHindsight> http://chicago.craigslist.org/nch/bfs/5424450063.html "Developed a control problem 15 years ago and has not been in use since." "Was only used for plastic machining."
[11:07:18] <CaptHindsight> the only thing missing was "the operator was a little old lady that only came in on Sundats"
[11:07:34] <PetefromTn_> hehe
[11:07:57] <CaptHindsight> lotsa rust for a mill thats never used
[11:07:57] <Tom_itx> maybe you should hire the same guy
[11:07:58] <PetefromTn_> yeah we always cut soft cheese on it and cleaned it every time we used it
[11:08:20] <PetefromTn_> Tom_itx I wish I could but he is only a local mover.
[11:08:38] <PetefromTn_> besides we gotta move the lathe too...
[11:09:29] <Tom_itx> does he have a brother? :D
[11:10:03] <PetefromTn_> heh why you wanna date? ;)
[11:10:20] <Tom_itx> not with him
[11:10:36] <PetefromTn_> he told me that their trucks are only certified to run local
[11:10:44] <PetefromTn_> or licensed or whatever
[11:10:53] <Tom_itx> so?
[11:11:00] <PetefromTn_> if he gets caught going over certain lines he can get fined big time
[11:11:46] <PetefromTn_> I wish I knew a sexy chick down in Florida I could set him up with to change his mind but I am out of ideas LOL
[11:13:03] <PetefromTn_> I got a bid on my ad on uship from a guy in pennsylvania
[11:13:49] <Tom_itx> http://www.leecontracting.com/?gclid=COW-oM3A1MoCFQ6RaQod-gsBHw
[11:13:53] <Tom_itx> they sound expensive
[11:13:55] <PetefromTn_> he said he has an F350 diesel dually and a tilt bed heavy equipment trailer and said he could move both machines to PSL for around $1700 bucks. Seemed quite reasonable especially if he can load and unload them...
[11:14:51] <Tom_itx> http://www.heavyequipmentmoving.com/
[11:15:39] <archivist> shiftyershit.com
[11:15:43] <Tom_itx> http://www.equipmentshippers.com/
[11:16:20] <PetefromTn_> I already spoke with two PRO riggers and they are crazy what they want to move it...
[11:16:39] <PetefromTn_> I think my best bet will be with these Uship guys
[11:16:57] <archivist> or stay put, its cheaper to not move
[11:16:58] <Tom_itx> doesn't sound too bad really
[11:17:09] <PetefromTn_> no it doesn't really
[11:17:30] <PetefromTn_> if I could get them both into a storage unit safe and sound in PSL for under $2k I would be quite pleased I think
[11:18:33] <PetefromTn_> archivist yeah I am sure it would be...but then I would not be where I want to be in Florida near family and friends enjoying the surf and sand and fishing and seafood etc etc. etc.
[11:19:02] <PetefromTn_> I would still be up here in the icebox freezing my baguettes off ;)
[11:19:36] <Tom_itx> zee's in the icebox
[11:19:37] <Tom_itx> not you
[11:21:35] <Erant> $1700 to move some heavy machinery from TN to FL? Seems reasonable
[11:22:42] <Erant> And he has to come from PA?
[11:22:55] <Tom_itx> yeah, lemme know when it's all loaded and ready and i'll jack the truck and have it rerouted to Ks
[11:24:23] <PetefromTn_> I agree I was pleased with those prices. The one from Pa seemed pretty serious about it and knew what he was talking about it seemed.
[11:25:00] <PetefromTn_> Probably wants to make a trip to Florida and figures he can make money along the way so why the hell not huh
[11:28:46] <Erant> That's a long-ass drive.
[11:30:40] <Erant> Now that I've got a nice library of stuff set up, this CadQuery thing is starting to get real useful.
[11:31:25] <Erant> "I want a Nema-23 cutout, at offset X in this body" : make_nema23(body.faces(">Z").translate((p_nema23_offset, 0, 0)))
[11:35:47] <CaptHindsight> Uship is good for the trucking part if you can work out the load and unloading
[11:36:28] <PetefromTn_> well like I said this guys appears to be able to do both...
[11:36:33] <CaptHindsight> I got some really dumb responses from Uship at times asking if the machine could be boxed
[11:36:58] <archivist> yes, in an effin big box
[11:37:15] <CaptHindsight> PetefromTn_: what will he use for loading?
[11:37:49] <PetefromTn_> http://controversialtimes.com/issues/constitutional-rights/this-marine-saw-a-deputy-in-trouble-what-he-did-next-has-people-calling-him-a-hero/ This is an awesome story and the facebook comments on it are freaking HILARIOUS!
[11:38:18] <PetefromTn_> apparently he has a heavy duty hydraulic tilting trailer with a winch on it...
[11:38:26] <CaptHindsight> tilt bed with a winch?
[11:38:34] <PetefromTn_> thats what he said
[11:41:29] <CaptHindsight> https://www.youtube.com/watch?v=-VODfrbLkQA Hydraulic assist Tilt bed trailer getting loaded
[11:43:57] <t12> lol @ the moustache
[11:45:07] <PetefromTn_> t12 I know right... Only a real man could pull that off LOL
[11:45:43] <t12> style moustache into ar15
[11:45:43] <CaptHindsight> just don't hire this guy https://www.youtube.com/watch?v=iwXqWt6FsJY
[11:47:05] <t12> https://www.youtube.com/watch?v=wYi24D9lHqc&t=12s
[11:47:21] <PetefromTn_> man I drove truck for a very short time and I KNOW how hard it can be to get into some of the places drivers need to get into...it REALLY sucks..
[11:48:22] <Erant> CaptHindsight: Couple of 2x4's will make quick work of that :/
[11:52:13] <CaptHindsight> https://youtu.be/WIy417zSFWk?t=1m21s thats why the other 17 wheels are there
[12:00:35] <CaptHindsight> there are several youtube videos from truck dash cams of idiot drivers, these don't even come close to the idiots I come across
[12:01:37] <CaptHindsight> what you need is a dash cam in a small car to really capture idiots
[12:02:12] <PetefromTn_> my experience is that most drivers are very cautious and careful after all it is their livelihood if they screw up they are in BIG trouble both legally and financially...
[12:02:54] <PetefromTn_> as they say there are OLD drivers and there are BOLD drivers but there are no OLD BOLD drivers ;)
[12:03:00] <CaptHindsight> sure truck drivers
[12:03:03] <t12> sf on the other hand
[12:03:18] <t12> someone will flat run you over in an intersection at night in the rain to get 30seconds on a light
[12:03:30] <t12> while running a red
[12:03:40] <CaptHindsight> it's the SUV and minivan drivers that are generally the worst I come across, closely followed by the pickup truck
[12:04:06] <t12> here its bmws and audis and such
[12:04:24] <CaptHindsight> yes, in larger cities
[12:04:46] <Erant> I ride a motorcycle, minivans are the worst offenders when it comes to trying to merge into you, or just generally not paying attention
[12:05:08] <Erant> Probably because they have kids in the back and are more focused on trying to get them to shut up than whether or not they're about to kill a biker.
[12:06:07] <CaptHindsight> I stopped riding a motorcycle years ago. I have friends that have been hit on every bike they own
[12:06:50] <CaptHindsight> I used to get rear ended at stop lights in my convertible with the top down
[12:08:11] <Erant> CaptHindsight: I've been hit before. Cabbie thought he could make the left in an intersection...
[12:08:28] <Erant> He couldn't.
[12:08:31] <PetefromTn_> hey asshats I drive a minivan!! :(
[12:08:50] <Erant> Do you have whining kids in the back?
[12:08:58] <PetefromTn_> occasionally
[12:09:08] <PetefromTn_> but mostly it is just me trying to get where I am goin'
[12:10:00] <PetefromTn_> I find most of the little cars are driven by the shitheads predominately... they never seem to know where they are going and they always are weaving in and out of traffic etc. etc. etc.
[12:10:18] <Erant> We're also stereotyping. It makes me feel horrible, but the worst offenders are asian moms in minivans.
[12:10:22] <PetefromTn_> always on the phone, texting, doing their makeup, etc.
[12:10:49] <Erant> I hate that I'm stereotyping, but it helps keep me alive on a day-to-day basis, so...
[12:10:57] <PetefromTn_> I honestly love my minivan LOL
[12:11:19] <Tom_itx> Erant, well.. my neighbor across the street pulled into their driveway and took out their neighbor's fence
[12:11:23] <PetefromTn_> have had a couple over the years... best vehicle for moving your stuff around and lots of room for the kids and whatnot
[12:11:27] <Tom_itx> stereotyping?
[12:11:32] <Erant> Tom_itx: How do you even...
[12:11:37] <Erant> O_o
[12:11:43] <Tom_itx> and high centered it
[12:11:53] <zeeshan|2> rofl
[12:11:56] <zeeshan|2> you drive a minivan?!?
[12:11:57] <zeeshan|2> :D
[12:11:57] <Tom_itx> haha
[12:12:01] <zeeshan|2> hahahaha
[12:12:05] <zeeshan|2> sorry :P

[12:16:56] <CaptHindsight> I got stuck with Chrysler minvan for a rental due to a schedule screw up...
[12:17:08] <Jymmm> PetefromTn_: zebra riverkill?
[12:17:46] <CaptHindsight> it had 2 modes, 0-95% gas pedal would slowly accelerate you as though you were in a sailboat...
[12:18:27] <Jymmm> and the other mode?
[12:18:30] <CaptHindsight> 96-100% pedal and it would spin the front wheels, I don't know how much tread was on those tires after that weekend
[12:18:39] <Jymmm> lol

[12:24:46] <CaptHindsight> just noticed that it's 46F outside, going out
[12:25:02] <Jymmm> 34F and sunny
[12:25:49] <CaptHindsight> Jymmm: has your snow cover melted?
[12:26:00] <miss0r> I am realy having a hard time figuering out how fast (feed/speed) I should run my newly made fly cutter... I have read a bit about it online, but I was hoping to find a calculator, as this has a variable diameter. Do you guys have any hints?
[12:26:29] <Jymmm> CaptHindsight: No snow for a while just has been NON STOP RAIN for days lately
[12:26:51] <Jymmm> Solutions for Welding Zinc Coated Steels http://awo.aws.org/2015/02/solutions-for-welding-zinc-coated-steels/
[12:27:48] <CaptHindsight> miss0r: probably slower
[12:27:56] <Jymmm> CaptHindsight: Just call me Noah, they had been lining up outside two by two
[12:28:22] <miss0r> CaptHindsight: at the moment I am running at 178 rpm. feed at 20mm/min
[12:28:25] <CaptHindsight> miss0r: use the outside diameter of the cutter and start from there
[12:28:53] <miss0r> indeed. but I can't seem to find the reccomended chip load for the inserts I am using
[12:28:56] <CaptHindsight> whats the diameter and depth of cut?
[12:28:57] <archivist> noise and finish is a good indicator
[12:29:22] <CaptHindsight> what material is being cut?
[12:30:11] <miss0r> at the moment the diameter is 164mm and the depth of cut is 0.06mm.
[12:30:17] <miss0r> I am cutting low carbon steel
[12:30:22] <CaptHindsight> when the inserts break and the spindle stalls you got too greedy
[12:30:41] <miss0r> CaptHindsight: on a 5hp spindle - so I hope it won't come to that ;)
[12:30:43] <Jymmm> CaptHindsight: Adamantium
[12:31:41] <miss0r> when I finish a pass of the surface it looks like it was precision ground. but I was hoping for something a bit more mirror like
[12:32:21] <miss0r> the surface finish is leveled within 0.001mm. and it feels good to the touch. but still not a mirror
[12:33:25] <_methods> you usually need to precision grind something to make it look like it was precision ground
[12:33:28] <_methods> lol
[12:33:38] <miss0r> so my tram is very good it seems. I just want something shiny! :)
[12:34:18] <miss0r> _methods: it has the same surface-look. not quite a mirror finish but very leveled
[12:35:21] <miss0r> also: when using carbide inserts - shouldent the cutaway be blueish of color?
[12:35:37] <miss0r> or does that not go for fly-cutters?
[12:36:04] <_methods> it just depends on the material and the size of the chip
[12:36:31] <CaptHindsight> thanks Jymmm, now it's raining here
[12:36:33] <miss0r> well - chip is very small/thin.
[12:36:35] <_methods> at .06mm depth of cut i doubt you're getting much of a chip
[12:37:02] <_methods> that's probably not even the radius of your insert
[12:37:09] <miss0r> just being carefull with my new machine here :) I just got it in here last week.
[12:37:14] <_methods> tool nose radius that is
[12:37:23] <zeeshan|2> miss0r: which insert are you using
[12:37:35] <miss0r> althou the nose radius is quite small, I think you are correct ;)
[12:37:38] <_methods> hehe don't want to break the new toy on the first day

[12:38:29] <Jymmm> CaptHindsight: Sorry man, it's still sunny here, but it was yesterday morning too then did a sneak-attack in the evening.
[12:38:32] <miss0r> indeed. I used a 'bore' tool holder for the job.
[12:38:41] <miss0r> it was what I had laying around
[12:39:04] <zeeshan|2> 0.4mm nose radius :)
[12:39:29] <zeeshan|2> but usually for carbide, cutting edge radius is like 0.025 mm
[12:40:06] <zeeshan|2> so that should tell you your min chip load

[12:41:08] <CaptHindsight> Fly Cutter Cutting a Mirror Finish on a 9"W x 18.5"L HRS plate in one pass
[12:41:55] <miss0r> CaptHindsight: i've seen it. and I have also druled about it.
[12:42:09] <miss0r> zeeshan|2: Yeah. I need to read more about it :)
[12:42:44] <zeeshan|2> one you know feed you can figure out the surface finish
[12:42:58] <CaptHindsight> so they are at 0.025mm depth vs your 0.06mm
[12:42:59] <zeeshan|2> theoretically its R_t = f^2/(8R_n)
[12:43:03] <zeeshan|2> R_n = nose radius
[12:43:08] <miss0r> also, only an idiot like me would stand in line of fire wearing a sweater... all the cutoff just sticks to me like a magnet
[12:43:13] <zeeshan|2> R_t = max roughness = ~ 4-7 R_a
[12:43:21] <zeeshan|2> f = chipload
[12:44:11] <miss0r> the max roughness... erh... what number is that?
[12:44:53] <CaptHindsight> so if you are taking too much out your surface will be rougher than if you take less
[12:46:04] <zeeshan|2> its hard to explain over text
[12:46:08] <zeeshan|2> but let me take a ss of my notes
[12:46:20] <miss0r> indeed. I will look up this formula online and get a bit wiser :)
[12:46:38] <zeeshan|2> http://i.imgur.com/yMNOLsg.png
[12:46:51] <zeeshan|2> that should make it pretty clear :P
[12:46:58] <CaptHindsight> if you increase your feedrate and keep the rest the same it will start to look like a vinyl record
[12:46:59] <miss0r> indeed. thank you :)
[12:47:12] <miss0r> CaptHindsight: goes without say ;)
[12:47:26] <zeeshan|2> this formula will also tell you
[12:47:31] <zeeshan|2> that you cant get better finishes than grinding :P
[12:47:36] <zeeshan|2> or lapping!
[12:47:56] <miss0r> indeed. I don't have a surface grinder here - So I will have to make do
[12:48:30] <CaptHindsight> is that what Lap dogs are for?

[13:16:00] <Kucharsky> Hi there, do you guys know of any syntax coloring plugin for gedit?
[13:16:22] <Kucharsky> I mean gcode code syntax highlighter
[13:16:24] <Kucharsky> ?
[13:19:57] <_methods> isn't syntax highlightin in gedit by default?
[13:29:14] <miss0r> it seems the first 5-6cm of the workpeice is mirror finish. then the carbide insert wears out and it starts looking a bit foggy in the surface - in orher words: am I too hard on it?
[13:29:52] <cpresser> CaptHindsight: yep, those liik quite similar
[13:30:23] <Kucharsky> methods it does not seem to work this way
[13:34:36] <_methods> oh gcode
[13:34:59] <_methods> i only know of paid gcode syntax highliters
[13:38:24] <archivist> you can edit the the highlighting

[13:39:59] <Tom_itx> http://www.cnc-club.ru/forum/viewtopic.php?t=80
[13:40:20] <archivist> and http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Highlighting_In_Gedit
[13:40:37] <Tom_itx> 2nd link mentions that
[13:40:44] <_methods> i've just use cimco
[13:40:59] <Tom_itx> i just use black and white
[13:41:47] <_methods> cimco has a nice backplot function so if you're tryin to figure out what some random gcode file is it can be helpful
[13:45:20] <Kucharsky> Thank you guys for help
[13:45:50] <Kucharsky> _methods: is cimco editor expensive?
[13:46:17] <Kucharsky> _methods: does it work on linux?
[13:48:05] <_methods> it's expensive and it works in wine
[13:48:10] <_methods> but not native
[13:48:31] <Erant> Sublime text has a highlighter: https://github.com/themachinist/gcode-syntax-highlighting
[13:48:51] <Erant> And - of course - vim has one: http://www.vim.org/scripts/script.php?script_id=4910
[13:49:03] <_methods> ah cool i'll have to try that sublime one
[13:49:19] <_methods> i use sublime for most stuff nowadays
[13:49:48] <Erant> emacs undoubtably has one, but I don't particularly feel like touching emacs with a 10ft pole.
[13:49:51] <Erant> So
[13:50:01] <_methods> i rarely use cimco unless i need the backplot
[13:50:13] <_methods> but linuxcnc with axis simulation should do the same thing
[13:51:59] <_methods> or to drip feed something
[13:57:29] <_methods> http://www.cimco.com/download.php3
[13:57:42] <_methods> they have a free feed and speed calculator program on there
[13:57:49] <_methods> i've never tried it before
[13:58:08] <_methods> i guess you can use their stuff free for a month too if you just want to test it out
[14:12:40] <zeeshan|2> 4.42
[14:20:38] <Kucharsky> I'm trying out sublime
[14:20:57] <Kucharsky> never used this editor befor but looks awsome at first glance
[14:46:24] <d42> it is quite good if you have no regard for your freedoms
[14:51:28] <Kucharsky> Hey folks, I'am editing demo linuxcnc ini file (axis.ini) For some reason in ini file for axis Z there is this comment for value MAX_LIMIT (how deep down my tool can go)
[14:52:00] <Kucharsky> # Normally the Z max should be 0.000!
[14:52:00] <Kucharsky> # The only reason it's greater than 0 here is so that the splash screen
[14:52:00] <Kucharsky> # gcode will run.
[14:52:00] <Kucharsky>
[14:53:02] <Kucharsky> But when I try to run sample program "3d chips.ngc" program start from -27 coordinate on Z and axis says it will not run this program
[14:53:34] <Kucharsky> I'm puzzled
[14:56:55] <lv-esad> hi there
[14:56:56] <Kucharsky> Sorry I ment Z max is 0 but program wants to go to z = 10
[14:57:38] <Kucharsky> how do I run this program when It's forbiddent in config to set Z_MAX > 0
[14:57:39] <lv-esad> is there anyone with a chinese lasercutter cnc ?
[14:57:40] <Kucharsky> ?
[14:59:10] <Jymmm> CaptHindsight: it's hailing
[15:01:58] <os1r1s> Kucharsky Wouldn't you need min_limit to be < -27?

[16:24:53] <JT-Shop> Kucharsky: http://gnipsel.com/linuxcnc/g-code/index.html
[16:33:37] <Kucharsky> JT-Shop: Thank you. I'm in the process of reading L.cnc documentation. There is a section on programming there but It's not straightfoward for begginer like me
[16:34:32] <Kucharsky> JT-Shop: I was thinking on reading sth. more tutorialish ;) Thanks
[16:36:27] <JT-Shop> that's why I wrote the tutorial to complement the documents
[16:44:50] <PetefromTn_> well just ordered four Maritool variable flute EM's for this steel plate since I just snapped another one LOL. 2nd day air hopefully they get here by tuesday along with the other engraving cutters I ordered from BitsandBits.com LOL
[16:50:26] <JT-Shop> we had a good time in Franklin TN...
[16:55:25] <PetefromTn_> never been there. Been to Pulaski tho...
[17:04:07] <PetefromTn_> http://i.imgur.com/DFBk3Mr.jpg :D
[17:05:18] <jthornton> how the heck do you weld that?
[17:07:24] <MrSunshine> ough someone got their welding cut out for them ...
[17:07:26] <PetefromTn_> VERY carefully ;)
[17:07:46] <PetefromTn_> actually the way I am going to do it is
[17:08:04] <PetefromTn_> take a single runner from the manifold plate to the merge off,
[17:08:19] <PetefromTn_> polish the snot out of the entire run and tack it more if necessary
[17:08:33] <PetefromTn_> then plug and back purge that runner
[17:08:40] <PetefromTn_> then tack it back in place
[17:08:46] <PetefromTn_> remove the next one
[17:08:49] <PetefromTn_> and so forth
[17:08:51] <PetefromTn_> and so on
[17:09:12] <jthornton> wow that has got to be a pain
[17:09:33] <PetefromTn_> honestly the hardest part is the polishing
[17:09:34] <CaptHindsight> Jymmm: cats and dogs here now, some look on fire, could be wrong :)
[17:09:58] <PetefromTn_> but since this is the very first one a prototype we had to figure out where everything would fit...
[17:10:43] <jthornton> are you going to weld the places that are hard to get to before you put the runner back?
[17:11:23] <PetefromTn_> like I said I will Tig weld the entire runner each joint all the way around and then put it back in place and tack it there...
[17:11:39] <jthornton> ah I missed that part
[17:11:41] <PetefromTn_> then once all three are back in place Tig weld the flange and the merge
[17:11:48] <PetefromTn_> do you guys like it?
[17:11:56] <jthornton> it's sweet
[17:12:05] <PetefromTn_> http://i.imgur.com/QxvrOMl.jpg
[17:12:17] <PetefromTn_> this is a mock up in the car with the three rotor motor in position
[17:12:25] <jthornton> I can really appreciate the effort that goes into something like that
[17:12:38] <PetefromTn_> its not simple LOL
[17:13:07] <PetefromTn_> http://i.imgur.com/aIHuK2K.jpg and with the Borg Warner in position..
[17:13:10] <jthornton> I know
[17:14:29] <PetefromTn_> it also still needs to be completely polished, tig welded, we also have to add the wastgate tubes and locate them, then once the manifold is complete we will need to make the downpipe and the rest of the intake tubing...
[17:14:47] <PetefromTn_> quite a bit of work getting the complete system mocked up and working
[17:14:55] <jthornton> what is it for?
[17:14:59] <PetefromTn_> then we get to make the smae thing again and again...
[17:15:11] <PetefromTn_> its for that car and a couple others...
[17:15:40] <PetefromTn_> there are three 3 rotor builds going on at the shop right now and another one that is supposed to be finish the kit and mail it to the customer for them to install...
[17:16:48] <PetefromTn_> I just thought it looked kinda cool all twisty and turny like that and I figured you guys might appreciate it... All the flat flanges I machined on my Cincinatti Arrow 500 VMC with LinuxCNC!
[17:16:50] <jthornton> so custom work
[17:17:15] <jthornton> dang I have 1.5 GB of band width to use tonight
[17:18:03] <PetefromTn_> yeah its custom they don't come with the 20B motor and all of this is sorta custom altho it is not new. The design of mine is new but this setup of motor, turbo,car has been done quite a few times...
[17:19:49] <jthornton> what kind of car is it?
[17:20:20] <PetefromTn_> its for an RX7 FD
[17:21:41] <PetefromTn_> http://i.kinja-img.com/gawker-media/image/upload/v16hakd5mftbqt8epgly.jpg Goes in something like this...
[17:22:49] <jthornton> cool, is the 3 rotor engine a kit?
[17:22:53] <Jymmm> CaptHindsight: Fire Roasted from the sky!!! Got coleslaw?
[17:24:19] <PetefromTn_> no not a kit really... the 20B motor came in a sedan mazda made in Japan and a few other vehicles but never in the RX7 that I am aware of. It takes custom motor mounts and a custom oil pan setup to clear the subframe crossmember and a few other things along with the turbo manifold stuff etc.
[17:24:44] <jthornton> ah a graft from another car
[17:24:51] <jthornton> that makes more sense
[17:24:55] <PetefromTn_> yeah basically
[17:25:18] <PetefromTn_> they sure sound amazing and can make a bunch of HP pretty effortlessly.
[17:26:06] <PetefromTn_> they have one that was built previously in the shop now that runs and it sounds amazing and it is not even really a built motor. Just has a street port and single turbo setup. Still made like 750hp apparently...
[17:26:36] <jthornton> holy crap batman that's a bunch of power for a small car
[17:26:54] <PetefromTn_> yeah I think so too LOL
[17:27:28] <PetefromTn_> but the ones they are building now should be considerably more powerful with bridgeports and bigger turbos, larger diameter tubing etc. etc...
[17:28:07] <PetefromTn_> do you think the tubes flow well?
[17:28:17] <PetefromTn_> I mean aesthetically
[17:28:41] <jthornton> from what I see yes they will look like a snake wrapped around more snakes
[17:28:48] <jthornton> very cool
[17:29:19] <zeeshan-mill> la la la
[17:29:26] <zeeshan-mill> someone operate this machine
[17:29:36] <PetefromTn_> this one was my own idea and I was not sure if other people would feel that way about it. I think it looks pretty cool but its nice to get others opinions...
[17:30:39] <jthornton> the mock up photo looks the coolest and that is what you would see when you pop the hood
[17:30:46] <zeeshan-mill> damnit i cant open your links pete
[17:30:48] <zeeshan-mill> machine runnin
[17:30:55] <PetefromTn_> oh sorry LOL
[17:31:17] <zeeshan-mill> i want to see
[17:31:17] <PetefromTn_> its the 3 rotor turbo manifold I have been designing and building over at the race shop
[17:31:28] <zeeshan-mill> nice!!
[17:31:33] <zeeshan-mill> for what turbo
[17:31:46] <PetefromTn_> Borg Warner
[17:31:54] <zeeshan-mill> s452?
[17:31:57] <zeeshan-mill> or whatever its called
[17:31:58] <PetefromTn_> it will fit EFR
[17:32:05] <zeeshan-mill> ah
[17:32:07] <PetefromTn_> internal wastegate
[17:32:19] <PetefromTn_> but this particular one will have external WG's
[17:32:30] <PetefromTn_> somewhere wherever we can stick them anyway LOL
[17:32:42] <PetefromTn_> can you see it then?
[17:54:26] <jthornton> I should learn how to make a hybrid install of Linux Mint with LinuxCNC
[17:58:31] <Tom_itx> are we all having fun this evening?
[17:59:25] <PetefromTn_> meh not really I am kinda stressed the hell out over all of this moving and finishing stuff around here ;)
[18:00:19] <Tom_itx> i was gonna write some code but after updating some i've about had it
[18:00:55] <Tom_itx> not gcode.. other stuff
[18:01:00] <jthornton> I'm building a new J1900 for the BP
[18:01:41] <Tom_itx> nice
[18:01:55] <jthornton> had a full day a bit of the Natchez Trace Parkway ride and back country
[18:01:57] <Tom_itx> i'm running a couple of those here
[18:02:01] <Tom_itx> win7 on em for now
[18:02:19] <jthornton> blew my mind when the usb keyboard didn't work
[18:02:53] <jthornton> well it didn't boot up nice...
[18:04:11] <jthornton> jibberish on the screen
[18:04:53] <Tom_itx> i booted 10.04 up on one once but really didn't run the mill with it alot
[18:05:17] <jthornton> do you recall how to get to the boot menu?
[18:05:36] <Tom_itx> not for sure
[18:05:44] <Tom_itx> maybe you his esc while it's coming up?
[18:05:55] <Tom_itx> i can't remember
[18:07:03] <jthornton> shift
[18:08:41] <jthornton> LOL still wondering where my solder station is...
[18:13:53] <Frank__> helloes
[18:14:19] <Frank__> anyone running heavy cnc router?
[18:16:04] <membiblio> Frank - a heavy router or something called heavy cnc?
[18:16:09] <membiblio> heavy.. :)
[18:16:19] <membiblio> not i
[18:16:31] <jthornton> I used to be heavy but now I'm not
[18:16:49] <Frank__> cuz i want some info on good z axis for wood
[18:16:52] <membiblio> they look nice
[18:16:59] <Frank__> i dont know if i should go with steel or alum
[18:17:17] <Frank__> my gantry is going to weight with z axis on about 150kg or more
[18:17:28] <Frank__> for 1.3mts
[18:45:36] <Jymmm> Frank__: you can use it for weight lifting =)
[18:50:41] <Frank__> lol, its out of my league!
[18:51:18] <XXCoder> just hulk up ;)
[18:51:39] <XXCoder> world would be different if anyone could hulk up
[18:52:39] <XXCoder> and suepr steachy pants would be very popular.
[18:53:41] <Frank__> what weight do you think would 1kw servomotor (panasonic) move at around 1000 ipm? imposible question right? haha
[18:56:47] <Sync> depends on a lot of variables
[19:06:59] <Frank__> okey can i try a different question? :D coupling to ballscew, timing belts or spring coupler, idk if its called like that
[19:10:26] <jdh> do you need gearing, or would the motor be in an awkward position at the end of the screw?
[19:11:34] <pcw_home> A 1k servomotor can move several tons at 1000 IPM, jut not accelerate very fast
[19:11:49] <pcw_home> s/jut/just/
[19:15:01] <Frank__> OMG
[19:15:04] <Frank__> several tons?
[19:15:23] <Frank__> i think i have overpowered motors for my use
[19:15:46] <Ralith> you may be misunderstanding the relationships between torque, acceleration, velocity, and gearing
[19:15:54] <Frank__> actually, i have more rotor inertia than load inertia
[19:16:25] <Ralith> most things can move several tons
[19:17:11] <Frank__> well yeah, i should have clarifyed, its use is for a cnc router, so u can expect vels of 1000ipm etc etc moving 100kg each motor
[19:17:17] <radicaldev> My truck weighs several tons. I can move it =)
[19:17:34] <Frank__> with like the pedal? haha
[19:18:09] <radicaldev> Under normal circumstances. I've had to push it a few times, though.
[19:18:36] <XXCoder> lol http://www.commitstrip.com/wp-content/uploads/2015/11/Strip-Fantasia-650-finalenglish.jpg
[19:19:38] <radicaldev> XXCoder: Happens to the best of us.
[19:20:16] <witnit> Frank__: gearing, friction, inertia, also acceleration/deceleration requirements all play big factors on how much motor you really need
[19:20:35] <pcw_home> Yeah, you should make sure that you have torque for the peak cutting load at peak acceleration + some amount of headroom
[19:21:08] <Frank__> im in trouble if i over sized the motors?
[19:21:24] <Frank__> i should have gone with steppers all the way T_T way cheaper
[19:21:38] <witnit> depends on if the motors can destroy your hardware under unusual runaway situations
[19:21:52] <pcw_home> steppers max out around 200W
[19:22:02] <Frank__> this is 5x then
[19:22:11] <Frank__> 1kw 3.2nm 3000rpm panasonic servos
[19:23:03] <Frank__> still have to check my speed requirement thou
[19:23:11] <witnit> Im no expert on steppers but, i dont really think they have any respectable advantages over servo systems, other than torque at low speed and simplicity
[19:23:35] <Frank__> aaaaaand price
[19:23:47] <malcom2073> Price and simplicity
[19:24:07] <malcom2073> The disadvantages outweigh that if you're doing production or high risk machining
[19:24:10] <pcw_home> for small things they are much simpler (and being 50 poles are natively slow speed devices)
[19:24:52] <Frank__> why do you mean production work as disadvantage for steppers? durability? speed?
[19:24:56] <Frank__> both ? =D
[19:25:08] <malcom2073> Frank__: If you skip a step, you won't know until you're done and measure the part
[19:25:16] <Frank__> i intend to do production wood routing
[19:25:25] <witnit> providing you are putting together some large order of units using multiple motors, most people can afford to move up to a servo system and it just not be a big deal
[19:25:26] <Frank__> i see
[19:25:38] <witnit> not to mention servo systems are VERY flexible
[19:25:51] <Frank__> im afraid of blowing them up
[19:25:56] <witnit> fear not
[19:25:59] <Frank__> my friend
[19:26:01] <Frank__> hahaha
[19:26:02] <witnit> :)
[19:26:26] <witnit> just spend 100 on ebay and play with an encoder, motor and amp
[19:26:29] <malcom2073> Yeah, I replaced the servos on my mill with steppers because it was cheaper than buying new drivers, and easier than figuring out the tuning/etc
[19:26:40] <malcom2073> But I'm doing slow stuff, it's limited to 30ipm
[19:26:43] <Frank__> i already have the 4 servos
[19:26:52] <Frank__> even the z axis has 1kw panasonic
[19:26:58] <witnit> oh, I should read up and see what you have said
[19:27:02] <Frank__> yeah first build guys
[19:27:13] <Frank__> im going with mesa cards
[19:27:40] <malcom2073> Heh, nah,if you've already got the motors you're golden
[19:27:55] <Frank__> red botton to press i hope not
[19:28:39] <witnit> IMO drill some holes in a sturdy board and mount your motors all to it so you can do testing without them flopping around on the table
[19:28:41] <Frank__> i see
[19:28:54] <Frank__> this router has a max of 2.4mts on the long axis
[19:29:27] <witnit> just rough tune them on the table until you get it close and learn a thing or two, then move them to your build and retune them to accomodate the load they will be moving.
[19:29:32] <Frank__> good advice, ill keep that in mind
[19:29:37] <witnit> you will make it through it
[19:30:04] <witnit> what kind of feedback do you have?
[19:30:11] <Frank__> u mean encoder?
[19:30:16] <witnit> yeah
[19:30:36] <witnit> sometimes motors will have other types of feedback
[19:30:40] <witnit> like resolvers
[19:30:52] <witnit> encoders are very easy
[19:30:59] <Frank__> 2500p/r(resolution: 10,000) 5-wire serial incremental encoder
[19:31:02] <Frank__> copy pastee :D
[19:31:48] <witnit> do you know which cards you will get?
[19:32:14] <Frank__> i was thinking 5i25/6i25 and 7i85s
[19:32:46] <Frank__> i still havent finished assembly and painting
[19:33:08] <Frank__> i have to figure out z axis, build it, maybe at the same time setting up electronics
[19:35:03] <witnit> you already have your amps?
[19:35:13] <witnit> drives^
[19:35:34] <Frank__> yep, bundle with servos
[19:39:14] <Frank__> i should get going! thanks for the talk
[19:39:18] <witnit> nice I think you are going to be very pleased with the smooth quietness and speed, just be careful a runaway servo motor once its already attached to a hardware (often caused by accidently flopping a pair of wires like when replacing an encoder)
[19:39:45] <Frank__> ohh i have read about that
[19:39:55] <witnit> pinch points are bad keep your fingers outta tyhem :PO
[19:40:09] <Frank__> the error that cannot catch up and ends up flipping the servo or something alike
[19:40:09] <witnit> GL!
[19:40:30] <witnit> BIG RED BUTTON install it
[19:40:31] <witnit> :)
[19:40:36] <Frank__> thanks! ill be having some news these days
[19:40:45] <Frank__> hahahah
[19:54:39] <witnit> anyone have any experience with load cells? and possibly graphing the data
[21:00:03] <radicaldev> What are the main differences between the DMV8825s and Gecko 250s?
[21:06:02] <malcom2073> Different current ratings, midrange resonance cancellation, microstep configuration
[21:07:28] <malcom2073> The 250 is significantly quieter in stepping (cleaner signal)
[21:07:50] <malcom2073> Pretty much everything
[21:09:26] <radicaldev> The 8825 allegedly can do 1/32 steps, I'm not sure how useful a metric that is when evaluating a driver, but the big thing to me is: I can get 5 8825s for 10 dollars. Do I really NEED some serious drivers like the Gecko line?
[21:10:11] <os1r1s> radicaldev The geckos also change their stepping rate on the fly
[21:10:17] <os1r1s> radicaldev Which the 8825s will not
[21:10:33] <malcom2073> Depends entirely on what you're doing. If you're running a 3d printer with nema17's, the 8825 is great. If you're running a small router with nema23's, the 250 is great
[21:11:11] <malcom2073> The 8825's don't do well with high speed screw systems due to the lack of anti-resonance, but they do fine with belted systems and slower screw based machines
[21:12:00] <radicaldev> Interesting... but a lot of drivers out there don't have midband resonance compensation
[21:12:38] <os1r1s> The 8825s are more limited on current too
[21:13:00] <os1r1s> They don't have the protections either
[21:13:19] <malcom2073> Yes, a lot of cheap stuff is cheap :P
[21:13:37] <malcom2073> But again, depends on what you're doing. If you don't need anti-resonance, you don't need it
[21:14:03] <radicaldev> That seems crazy, to change the stepping rate while stepping... How does that work out to an accurate part?
[21:14:22] <os1r1s> radicaldev the driver takes care of it
[21:14:58] <os1r1s> So it sends full steps to the motor when needing to move fast. It sends 1/10 stepping when its moving slow
[21:15:05] <os1r1s> Makes for the best of both worlds
[21:15:15] <radicaldev> I see.
[21:15:16] <os1r1s> The computer just sends the 1/10 stepping
[21:15:25] <os1r1s> The driver does the rest
[21:15:54] <radicaldev> So essentially, with the Gecko drivers you can go faster, more quietly, and drive bigger motors
[21:16:04] <os1r1s> radicaldev Correct
[21:16:08] <radicaldev> with less risk of destroying the driver
[21:16:12] <os1r1s> That too
[21:16:54] <os1r1s> For 4 axis, a g540 makes a lot of sense
[21:17:43] <os1r1s> It includes the breakout board + an isolated VFD
[21:18:47] <radicaldev> I intend to get a G540 before I have 4 axis capabilities, but I've got to wait until after the IRS gets done with me. Company I work for still hasn't sent my 1099 =/
[21:19:48] <radicaldev> for now, I've got homemade drivers and some 8825s on the way.
[21:20:28] <os1r1s> radicaldev What kind of machine?
[21:21:30] <jfindley> the one you sold me
[21:22:01] <os1r1s> jfindley haha
[21:22:07] <os1r1s> You crack me up
[21:22:15] <jfindley> dunno why the other nick was used
[21:25:20] <jfindley> Anyway, I've got circuit board drilling down, but I want to play around with plastic, metal, and wood now before I buy a proper CNC machine.
[21:25:34] <jfindley> proper being very large, and fairly expensive.
[21:25:47] <os1r1s> jfindley So circuits have gone well for you?
[21:29:03] <jfindley> yes and no, I successfully routed some boards and that went well, but it just doesn't compare to the printer/paper/board/ferric chloride/water method.
[21:29:29] <jfindley> The long part of that process was drilling the holes, which the CNC machine excelled at.
[21:29:43] <os1r1s> jfindley Thats weird. I've gotten ones on that machine to SMD
[21:30:19] <jfindley> It's not that it's not capable, it just can't do them that fast.
[21:31:02] <os1r1s> It should be faster than ferric chloride
[21:31:11] <os1r1s> Much faster
[21:32:49] <jfindley> With the TinyG?
[21:32:52] <os1r1s> jfindley Yes
[21:33:15] <os1r1s> A 2x2 board with a reasonable number of SMD components should take less than 20 minutes
[21:33:44] <jfindley> Ok, maybe our process there differs.
[21:34:20] <os1r1s> Possibly. I did 7 arduino pro type boards in about 4 hours.
[21:34:31] <os1r1s> And I was pretty lax about starting them up
[21:35:10] <os1r1s> For that size mill, tinyg is perfectly capable
[21:39:27] <jfindley> What software were you using with the TinyG?
[21:40:35] <os1r1s> I'd build the circuit with eagle. Then I would use eagle2cad (If memory serves). Then I would send it with one of the serial programs
[21:42:33] <jfindley> Hmm. For circuit making, I use eagle, then print the layout onto dextrin coated 8 1/2x11 paper, stick that onto copper clad board (1/2 oz) and run it through a laminator, then soak it in water for about a minute, remove, dry, and sponge with ferric chloride.
[21:43:01] <os1r1s> jfindley pcb2gcode
[21:43:38] <os1r1s> That was the cam part of the program
[21:43:38] <jfindley> The etching part for a sheet that size takes about 15 minutes or so, then it's off to the shears to cut out the individual circuits, then they're fed several at a time to the CNC machine. I wrote my own controller in C++ because I didn't like what was available.
[21:43:55] <jfindley> yeah, I use pcb2gcode too, for the drill layer.
[21:44:07] <os1r1s> I use that for the etching and milling
[21:44:11] <os1r1s> and drilling
[21:44:48] <os1r1s> Its just a lot easier to hit go. Change bits 3 times. And then its complete
[21:45:17] <jfindley> The best one I used was some cloud based thing, but I like having everything in house.
[21:46:15] <jfindley> http://chilipeppr.com/
[21:47:30] <jfindley> os1r1s: How were you fixing the boards to the CNC machine?
[21:47:40] <os1r1s> jfindley double sided tape
[21:47:48] <os1r1s> carpet tape is easiest
[21:47:55] <jfindley> Oh yeah, you mentioned that. Carpet tape =)
[21:48:23] <os1r1s> jfindley http://os1r1s.com/?p=239
[21:48:25] <jfindley> I 3D printed some fixtures that did pretty well.
[21:48:44] <os1r1s> That was my first attempt before I tuned it a bit
[21:49:04] <os1r1s> jfindley You should be etching at about 6 times that speed
[21:49:52] <os1r1s> jfindley Look at etching is the first step
[21:49:54] <os1r1s> That video
[21:50:27] <os1r1s> jfindley If your 3d printed fixtures only clip the sides, you could have issues.
[21:51:12] <jfindley> os1r1s: Definitely, for etching. Drilling works out pretty well, though.
[21:52:20] <os1r1s> jfindley On that page you can see my vacuum fixture. That works even better
[21:53:01] <jfindley> os1r1s: Yep! It's something I want to mess around with one of these days.
[21:53:42] <jfindley> For now, i want to play with LinuxCNC and get used to general purpose milling
[21:54:48] <os1r1s> jfindley This gets you chilipeppr locally https://github.com/synthetos/TinyG/wiki/Chilipeppr
[21:55:35] <os1r1s> fwiw
[21:56:19] <jfindley> Those guys did a good job. I wrote my thing in around 20 hours or so.
[21:56:35] <jfindley> Not as fancy, but did exactly what I wanted =)
[21:58:05] <jfindley> Do you think the 8825s will work for this guy?
[21:58:18] <os1r1s> jfindley Yes. They should work ok for that
[21:59:14] <jfindley> If they can just hold me over til May I'll be satisfied with the $10 in amazon reward points I spent on them =)
[22:00:32] <os1r1s> jfindley I am in the process of CNCing a much larger mill :)
[22:00:38] <os1r1s> Can't wait to be done.
[22:00:45] <os1r1s> The time its taking is driving me crazy
[22:00:52] <zeeshan|2> which mill
[22:01:05] <os1r1s> zeeshan|2 A PM25-MV. Nothing like yours :P
[22:01:28] <zeeshan|2> box column
[22:01:29] <zeeshan|2> nice
[22:01:46] <os1r1s> zeeshan|2 Doing servos on it too. Direct feedback to linuxcnc
[22:01:51] <zeeshan|2> nice :D
[22:02:09] <os1r1s> I'm trying to figure out if I have to gear them up/down
[22:02:19] <os1r1s> zeeshan|2 Or I should say I'm hoping I don't need to
[22:02:40] <zeeshan|2> how much torque
[22:02:50] <jfindley> os1r1s: Are you taking video of this process?
[22:02:56] <os1r1s> jfindley No
[22:03:03] <jfindley> =(
[22:03:23] <os1r1s> zeeshan|2 The x/y have peak 350 oz/in but constant 50 oz/in
[22:03:37] <zeeshan|2> seems a bit small for a mill that size
[22:03:48] <os1r1s> zeeshan|2 And it will run .5 TPI ballscrews
[22:04:27] <os1r1s> zeeshan|2 If I gear them up, I'll have plenty of torque
[22:04:33] <jfindley> os1r1s: What materials will you be working on?
[22:04:37] <os1r1s> I was just hoping I didn't need to
[22:04:40] <zeeshan|2> but then you go slower :{
[22:04:40] <os1r1s> jfindley Mostly 6061
[22:05:21] <os1r1s> zeeshan|2 If I can cut with it direct drive just to make some adapters, I will be happy.
[22:06:34] <zeeshan|2> you will be able to
[22:06:52] <os1r1s> zeeshan|2 What do you think the max feed would be?
[22:06:53] <zeeshan|2> with the right combo of cutter size and depth of cut :D
[22:06:58] <os1r1s> hehe
[22:07:13] <zeeshan|2> i feel like if youre running a 1/4" cutter
[22:07:27] <zeeshan|2> you could prolly do 0.050 doc at 10 ipm easily
[22:07:52] <zeeshan|2> gotta test to see its capability :P
[22:07:59] <os1r1s> haha
[22:08:20] <os1r1s> If I do 8:1 gearing, it should do well
[22:09:19] <jfindley> zeeshan|2: That seems really slow.
[22:09:21] <os1r1s> zeeshan|2 That would still mean 250 IPM rapids, but 400 oz/in constant torque
[22:09:43] <os1r1s> jfindley That isn't that slow
[22:09:58] <zeeshan|2> we could really work out the math
[22:10:04] <zeeshan|2> to get a beter estimate
[22:10:13] <zeeshan|2> what diameter lead screw?
[22:10:32] <os1r1s> 16mm
[22:10:57] <zeeshan|2> ball screw?
[22:11:13] <os1r1s> Yep. 5mm pitch
[22:11:44] <zeeshan|2> so its not .5 pitch screws :P
[22:11:53] <zeeshan|2> .197
[22:12:07] <zeeshan|2> 5 TPI
[22:12:11] <os1r1s> .5 TPI
[22:12:14] <jfindley> os1r1s: https://www.youtube.com/watch?v=6j4AJjJb4A8 That's pretty close to this, right?
[22:12:21] <zeeshan|2> how are you getting .5TPI
[22:12:32] <os1r1s> It uses the RM-16 Metric C7 grade ball screws. 5mm Pitch (.508 TPI)
[22:12:38] <zeeshan|2> 5/25.4 = pitch in inches , 1/(5/24.4) = 5 tpi
[22:12:40] <os1r1s> ^ from the listing
[22:12:50] <zeeshan|2> either im tired as hell
[22:12:53] <zeeshan|2> or theyre doing the math wrong
[22:13:03] <zeeshan|2> math dun lie!
[22:14:07] <zeeshan|2> T = [F*D_p/2] * [ (L+pi*f*D_p) / (pi*D_p - fL)
[22:14:41] <zeeshan|2> f ~ 0.01 for a ball screw
[22:15:06] <os1r1s> Looking
[22:15:19] <os1r1s> Assume 5mm pitch for our discussion :) I know that part is right
[22:18:16] <os1r1s> Your math looks right. It seems like 5 TPI
[22:18:38] <os1r1s> zeeshan|2 ^
[22:19:10] <zeeshan|2> okay using the formula
[22:19:16] <PetefromTn_> Oh hell someone is questioning Zeeshan's maths...;)
[22:19:19] <zeeshan|2> you can say T = 0.82*F
[22:19:33] <zeeshan|2> convert the oz-in to a non retarded unit :P
[22:20:11] <os1r1s> jfindley https://www.youtube.com/watch?v=3cbaxVRqyjc
[22:20:19] <zeeshan|2> assuming it can put at 350 oz-in , thats 21.875lb-in
[22:20:45] <os1r1s> zeeshan|2 But do you focus on constant or peak torque when it comes to a servo?
[22:21:05] <zeeshan|2> do you have a chart
[22:21:08] <zeeshan|2> really the chart will tell
[22:21:12] <zeeshan|2> peak will give a good estimate
[22:21:18] <PetefromTn_> http://imgur.com/wXu4cmj ROFL
[22:21:38] <zeeshan|2> using peak, your motors can provide a cuting force in the axis direcvtion
[22:21:42] <zeeshan|2> of 27lb approx
[22:22:23] <os1r1s> And that include the 5 TPI screws in the calc?
[22:22:27] <zeeshan|2> yea
[22:22:39] <os1r1s> That doesn't seem like much
[22:22:49] <os1r1s> Though I'm not sure how much you need on a mill that size
[22:22:57] <zeeshan|2> more than that
[22:23:03] <zeeshan|2> if youre cutting steel
[22:23:22] <os1r1s> So if I gear it at 8:1. That would give me 216
[22:23:53] <zeeshan|2> yea but youre gonna go so slow
[22:23:54] <zeeshan|2> for rapids
[22:24:40] <os1r1s> zeeshan|2 Hmm, the wrong TPI strikes again. I had calced it would do 250 IPM
[22:24:46] <os1r1s> With 8:1
[22:24:51] <zeeshan|2> how
[22:24:52] <os1r1s> But that would be off
[22:25:06] <zeeshan|2> whats the max rpm of the motor?
[22:25:07] <zeeshan|2> 2000?
[22:25:09] <os1r1s> 4000 rpm motors.
[22:25:28] <os1r1s> Sorry, 4700
[22:26:35] <zeeshan|2> so 940 ipm at 4700 rpm
[22:26:47] <zeeshan|2> 117 ipm at 1/8
[22:26:52] <zeeshan|2> thats still prettyu good!
[22:27:00] <os1r1s> That would be about 78 turns per second. Or 15.6 IPS. or 936 IPM ungeared. Gearing it would get me to 117 IPM
[22:28:56] <zeeshan|2> im workin out the milling math
[22:29:10] <os1r1s> zeeshan|2 And I greatly appreciate your help.
[22:29:19] <zeeshan|2> if youre running a 1/4" cutter, assuming youre slotting
[22:29:25] <zeeshan|2> you can theoretically do a 0.25 " doc
[22:29:36] <zeeshan|2> so wayyyyyy more than i was thjinking
[22:29:42] <os1r1s> With 27 lbs?
[22:29:44] <zeeshan|2> you prolly wanna take half that
[22:29:48] <zeeshan|2> to give yourself a buffer
[22:29:48] <zeeshan|2> yea
[22:30:11] <os1r1s> At what feed?
[22:30:13] <zeeshan|2> this is all approx
[22:30:17] <zeeshan|2> 0.002 ipt
[22:30:19] <zeeshan|2> 2 flute cutter
[22:30:33] <zeeshan|2> so around 25-30 ipm
[22:30:40] <os1r1s> That would be hauling ass
[22:31:14] <os1r1s> Given I'm limited to 2250 RPM, I can't go near that
[22:31:49] <zeeshan|2> i hope i did the math right
[22:31:50] <zeeshan|2> checkin :P
[22:31:55] <zeeshan|2> my sense says its off
[22:31:56] <zeeshan|2> lol
[22:33:18] <zeeshan|2> fak
[22:33:21] <zeeshan|2> made a mistake
[22:33:36] <zeeshan|2> okay new numbers
[22:33:56] <os1r1s> hehe
[22:34:25] <zeeshan|2> 1/4" cutter, 2 flute, .25 woc, .25 doc, 0.001 ipt ,
[22:34:37] <zeeshan|2> so you can do 20 ipm
[22:34:38] <zeeshan|2> no prob
[22:34:46] <zeeshan|2> but you'd prolly want to take half the doc.
[22:34:51] <zeeshan|2> to keep a buffer
[22:34:57] <zeeshan|2> .125 doc is pretty damn good.
[22:35:01] <os1r1s> But limited to 2250 RPM I can't go near that anyway
[22:35:08] <os1r1s> I'll be stuck down around 8-9
[22:35:12] <os1r1s> IPM
[22:36:04] <os1r1s> Unless you think thats off
[22:36:26] <zeeshan|2> why are you limited to 2250 rpm
[22:36:34] <os1r1s> Max spindle speed
[22:36:39] <zeeshan|2> oh
[22:36:52] <zeeshan|2> yea that'll change things =-/
[22:36:57] <zeeshan|2> cause you need to maintain 0.001 ipt for sure
[22:37:02] <zeeshan|2> especifically if youre using carbide
[22:37:10] <zeeshan|2> thats going to be a touch one
[22:37:12] <zeeshan|2> *tough one
[22:37:33] <os1r1s> zeeshan|2 So that will keep me under 10 IPM
[22:37:40] <os1r1s> Most likely
[22:37:50] <zeeshan|2> yes
[22:37:57] <zeeshan|2> but then your tool will be ploughing
[22:37:59] <zeeshan|2> rather than cutting
[22:38:07] <zeeshan|2> but if you use hss youll be ok
[22:38:16] <zeeshan|2> the yg1 carbide cutters are nice too
[22:38:22] <jfindley> Still at 0.05" DOC?
[22:38:25] <zeeshan|2> they have cutting edge radius of approx 0.0005"
[22:38:38] <zeeshan|2> no jfindley, at 0.125-0.25" doc
[22:38:45] <zeeshan|2> i personally wouldnt exceed .1875"
[22:38:50] <zeeshan|2> dont want to stall the motor :P
[22:39:07] <zeeshan|2> os1r1s: i think if you did 4:1 ratio
[22:39:10] <zeeshan|2> you could cut steel :D
[22:39:15] <zeeshan|2> easily
[22:39:16] <os1r1s> zeeshan|2 That will be the goal
[22:39:22] <os1r1s> zeeshan|2 Not that I do it often
[22:39:29] <os1r1s> But I would like to be able to without thinking
[22:39:41] <zeeshan|2> i hate gear ratios on cnc
[22:39:46] <zeeshan|2> another bs source of error!
[22:39:49] <zeeshan|2> but sometimes it has to be done
[22:40:07] <os1r1s> Maybe 6:1 would be decent. That would give me a good multiple and still let me rapid at 157 IPM
[22:40:16] <os1r1s> And plenty of torque
[22:40:22] <zeeshan|2> yes
[22:40:29] <os1r1s> zeeshan|2 I was worried about what backlash it would introduce
[22:40:45] <zeeshan|2> if youre using those ebay ball screws
[22:40:49] <zeeshan|2> they'll be a source of backlash
[22:40:55] <zeeshan|2> need tweaking
[22:41:01] <zeeshan|2> mine had .004"
[22:41:07] <zeeshan|2> w/ the double nut i went down to 0.001"
[22:41:24] <zeeshan|2> the mxl or whatever those belts are called
[22:41:25] <zeeshan|2> from sdpsi
[22:41:33] <zeeshan|2> didnt do anything to bring in backlash
[22:41:44] <zeeshan|2> was happy about that :D
[22:41:58] <os1r1s> zeeshan|2 I know the GT2 and HTD variants are supose to minizmize it
[22:42:01] <os1r1s> minimize it
[22:42:12] <Erant> I need to ream a blind hole for a taper pin. My reamer doesn't go in deep enough... Should I just cut it off?
[22:42:14] <os1r1s> But I am/was skeptical
[22:42:32] <Erant> It was a cheap reamer, I have no issue cutting it. Just wondering if that's what you're supposed to do.
[22:42:44] <zeeshan|2> erant i do the same thing with pipe taps
[22:42:44] <zeeshan|2> lol
[22:42:47] <zeeshan|2> when the hole is blind
[22:43:00] <os1r1s> zeeshan|2 Man, thank you for all your help. I've been batting this around for a few weeks now.
[22:43:07] <zeeshan|2> np man
[22:43:09] <Erant> I figured that was the solution. :)
[22:48:54] <Erant> I just replaced my Z axis with an 'ebay' ballscrew.
[22:49:18] <Erant> There's stil 0.005" there somewhere, but I think it's just the belts/pulley.
[22:49:48] <Erant> It's not the ballscrew (unless I f'ed it up somehow), should be C3 grade.
[23:50:34] <Crom_> there much better
[23:51:34] <Crom_> wow wind is really kicking up, Temecula CA south east of Los Angeles on I15
