[00:00:43] <XXCoder1> nice eh
[00:00:59] <zeeshan> yea
[00:01:21] <zeeshan> you sure you need such huge lead screws?
[00:01:25] <XXCoder1> I guess orange spots is place I inject grease
[00:01:29] <zeeshan> no
[00:01:40] <zeeshan> those are the ball returns

[00:01:44] <XXCoder1> ahh
[00:01:49] <zeeshan> the golden thing is the grease nipple
[00:01:57] <XXCoder1> cool
[00:02:12] <XXCoder1> it was only kit that has those size
[00:02:17] <XXCoder1> so yes I guess lol
[00:02:28] <XXCoder1> it was bit cheaper when I bought it

[00:08:47] <XXCoder1> 3 for less than $20 each
[00:08:56] <zeeshan> that is so cheap
[00:09:00] <zeeshan> considering how much it costs to make em
[00:09:47] <XXCoder1> yeah, probably will buy
[00:10:46] <XXCoder1> damn he dont also sell antibacklash coupler

[00:41:06] <Tom_itx> i used solid couplings on mine
[00:41:07] <zeeshan> i have the aluminum shit style coupler
[00:41:18] <zeeshan> lol tom
[00:41:29] <renesis> haha my taig has hollow plastic tube couplers
[00:41:31] <zeeshan> a little fiex is good :P
[00:41:34] <renesis> 4 tiny tubes per axis!

[00:41:36] <zeeshan> :D
[00:41:37] <renesis> wat
[00:41:39] <zeeshan> hi
[00:41:41] <renesis> hi
[00:41:44] <zeeshan> nice to see you here
[00:41:50] <Tom_itx> never had any problems... you need to get them aligned
[00:42:00] <renesis> i forgot i joined!

[00:42:59] <zeeshan> w/ a solid couling
[00:43:04] <Tom_itx> it's still running
[00:43:42] <Tom_itx> i've had it for probably 20 yrs or so
[00:43:53] <Tom_itx> in various forms
[00:43:59] <Tom_itx> upgraded a time or two
[00:44:36] <zeeshan> Tom_itx: see i was thinking running a solid coupling
[00:44:48] <zeeshan> by first mounting the motor and ball screw toghether
[00:44:51] topcyde_ is now known as topcyde
[00:44:55] <Tom_itx> you gotta get them aligned if you do
[00:45:07] <zeeshan> and then seeing where it naturally where the stepper sits
[00:45:15] <zeeshan> account for gravity
[00:45:26] <zeeshan> and then bolt it on the stepper bracket by shimming it accoridngly
[00:45:35] <zeeshan> is that how you kind of did it?

[00:47:33] <zeeshan> my brackets arent that style :P

[00:51:58] <renesis> tom_itx: thats standard step mounting for sherlines?
[00:52:39] <Tom_itx> it's not sherline's but quite similar i think
[00:53:03] <renesis> that thing makes my taig look huge
[00:53:38] <Tom_itx> i've done quite a bit with it but it *is* limited

[00:56:21] <Tom_itx> no, i wasn't looking for any
[00:56:34] <XXCoder1> lol I am
[00:56:43] <XXCoder1> its one of few parts I still need
[00:59:12] <XXCoder1> Think I just need 3 zero backlash couplers, nema 23 mounts, and some of those screws

[01:08:47] <tjtr33> zeeshan, re: " 5" diameter circle out of ss 304" consider making a punch & die?
[01:09:02] <zeeshan> tjtr33: yes i did
[01:09:14] <zeeshan> shearing will cause residual stresses at the shear interface
[01:09:18] -!- cjb has quit [Ping timeout: 240 seconds]
[01:09:22] <zeeshan> so i cant do that either
[01:09:38] <tjtr33> so will a spinning cutter, but you can judge
[01:09:54] <zeeshan> less than shearing

[01:11:34] <zeeshan> Jymmm: yea man

[01:18:07] <scooty_puff> what are 8 wire steppers? are they just like 4 wire but with 4 coils?
[01:18:35] <cradek> yep
[01:18:43] <cradek> split each coil in half
[01:18:45] <XXCoder1> those is called 4 phase right?
[01:18:48] <zeeshan> http://www.esuli.it/wp-content/uploads/2011/10/stepperWiring.png
[01:18:49] <cradek> no
[01:19:04] <cradek> the idea is you can put those pairs in series or parallel
[01:19:04] <XXCoder1> oh
[01:19:32] <zeeshan> http://probotix.com/stepper_motors/unipolar_bipolar/
[01:19:35] <zeeshan> this is a very simple site
[01:19:38] <zeeshan> that made me understand it
[01:19:44] <zeeshan> shows the benefits..
[01:19:54] <zeeshan> basically you end up finding out that you want bipolar paralle :d
[01:19:59] <zeeshan> for most torque!

[02:31:11] <XXCoder1> scooty_puff: linuxcnc is orogram to control cncs
[02:31:26] <XXCoder1> oddly we talk about cncs more than program here...
[02:31:39] <XXCoder1> diycnc is very dead
[02:31:50] <XXCoder1> *#diycnc channel
[02:31:53] <PetefromTn_> and we talk about basically anything that pops up quite often as well ;)
[02:32:59] <scooty_puff> this is random but i am in the process of writing my own cnc control program for a atmega644
[02:33:14] <scooty_puff> wierd i just stumbled in here
[02:33:47] <PetefromTn_> These guys could probably figure out how to run linuxCNC on about anything... Even a saltine cracker I think.
[02:34:48] <PetefromTn_> There are already some guys working with arduinos and beagle bone black stuff with linuxCNC.
[02:35:21] <PetefromTn_> altho I admit I don't know SQUAT about that stuff.

[02:39:21] <scooty_puff> i want to eventually strap a yag laser on to it
[02:41:00] <scooty_puff> like 2-40 watt and pulse it as fast as i can get it to go
[02:41:01] <jdh> you could strap a yak on it for testing. might do less damage.

[03:09:44] <XXCoder1> huh?? http://www.pbclinear.com/Linear-Plain-Bearings-with-Simplicity-Maintenance-free-Liner
[03:09:52] <XXCoder1> it looks like its for SBR rails
[03:09:57] <XXCoder1> but no balls?
[03:10:05] <CaptHindsight> XXCoder1: the plain bearings are polymer bearings
[03:10:16] <CaptHindsight> yeah no balls
[03:10:25] <XXCoder1> better? worse?
[03:10:51] <CaptHindsight> their polymer bearings are better than Chinese sbr ball bearings
[03:11:07] <CaptHindsight> watch the video... hold a sec...
[03:11:13] <XXCoder1> they do have 12 16 and 20. I has those sizes.
[03:11:26] <XXCoder1> problem is im not sure of external dim

[03:14:17] <tjtr33> hey i got that hurco running, took 1st cuts today
[03:14:22] <CaptHindsight> I'm checking into their lead times, the prices look good
[03:14:36] <XXCoder1> its my frame that will have worse effects on precision than bearings.

[03:20:41] <XXCoder1> good.
[03:20:57] <XXCoder1> those definitely is nice rails.
[03:21:37] <CaptHindsight> it's funny when you can just send them a sketch and have them design and give you a BOM in 1 day where the repcrap makers take months to come up with wobbly stages
[03:21:53] <XXCoder1> well
[03:21:56] <XXCoder1> more money
[03:22:19] <CaptHindsight> any machine designer can slap together a glue gun or dlp printer in an afternoon
[03:22:42] <XXCoder1> if I ever decide to make 3d pinter

[03:24:06] <XXCoder1> too bad I'm not using em lol
[03:24:25] <tjtr33> machine tools should be like legos, what do you do when the contract is over? take it apart, put parts on shelf, reconfig for next job run
[03:24:35] <CaptHindsight> XXCoder1: you can download 3d models of most automation components and layout a 3-5 axis system in a few hours
[03:25:02] <CaptHindsight> it's not a several weeks or months project

[04:04:39] <CaptHindsight> or the connection manager
[04:05:42] <revo14> when i installed debian no problem i didnt nothing
[04:05:58] <revo14> no problem for go to internet
[04:06:07] <revo14> i would like to have linuxcnc here

[04:08:29] <CaptHindsight> if you want to try you are on your own or you'll just have to ask here or the mail list about your problems
[04:08:56] <CaptHindsight> USB should just work, but not with Linuxcnc

[04:20:14] -!- Valen has quit [Quit: Leaving.]
[04:21:05] <revo14> really is very difficukt for me linux is difficult
[04:22:01] <PetefromTn_> Well I managed to get the new 7i77 card I ordered to replace the one I smoked installed in the machine. It seems to be working correctly and the green light turns on and flashes. I went up to the front of the machine and looked at the display and linux ubuntu had loaded and LinuxCNC had autoloaded without an error which I was getting before.
[04:22:07] <PetefromTn_> So that is good news.
[04:22:12] <tjtr33> it is very particular. each step must be done correctly before next step. slow works better :)
[04:22:38] <CaptHindsight> revo14: we have all been through what you are doing before :)
[04:22:46] <CaptHindsight> that's how you learn
[04:23:11] <CaptHindsight> or get fed up and become a Shepard
[04:23:19] <PetefromTn_> Now I need to figure out where I removed a 24v lead off a relay when the power supply burnt up. I am not sure which terminal it went on and I am gonna have to look carefully at my wiring diagram so I don't screw it up.
[04:23:48] <PetefromTn_> I am pretty sure where it goes but I want to MAKE sure before I hook it up and try to energize the servos.
[04:24:53] <PetefromTn_> It is late here now so I am gonna hit the sack and look at it in the morning when I am not so tired.
[04:25:18] <PetefromTn_> With any luck I will be back to machining parts tomorrow afternoon and I can get on with this retrofit.
[04:25:45] <PetefromTn_> Feel like SUCH a dumbass for screwing it up like I did.
[04:26:20] <zeeshan> PetefromTn_: howd the card burn?
[04:26:35] <zeeshan> the other day when i was hooking up the wiring for my lathe
[04:26:41] <zeeshan> i frigging reversed the polarity on the stepper driver
[04:26:41] <zeeshan> lol
[04:26:44] <zeeshan> 72VDC!!
[04:26:52] <zeeshan> it was like that for 5 minutes or so
[04:26:56] <PetefromTn_> I was trying to fix the spindle motor cooling fan setup which I did not realize had been disabled when I converted to modbus spindle control recently.
[04:26:56] <zeeshan> till i realized the drive wasn't powered up
[04:27:10] <zeeshan> luckily it worked after i reversed the polarity
[04:27:11] <CaptHindsight> heh, I've double checked my wiring and still put the 48V on the +5 and the +5V on the 48V
[04:27:46] <zeeshan> PetefromTn_: so you accidently hooked up a power wire
[04:27:49] <zeeshan> where it wasnt supposed to go?
[04:27:53] <PetefromTn_> My friend art was helping me rewire it to come on whenever servos were enabled and I accidentally hooked the wire to the wrong terminal on the relay.
[04:27:55] <CaptHindsight> sometimes you don't see your own mistakes, like proofreading your own writing
[04:28:02] <zeeshan> doh
[04:28:07] <zeeshan> CaptHindsight: i agree
[04:28:08] <zeeshan> lol
[04:28:11] <zeeshan> im used to doing car wiring
[04:28:23] <zeeshan> which isn't usually too damaging
[04:28:26] <zeeshan> if you do something wrong
[04:28:39] <PetefromTn_> Basically I ran 110v into a 24volt relay input and smoked the relay, the 24v power supply and the 7i77 card...
[04:28:39] <zeeshan> (youll find out fast enough!)
[04:28:53] <zeeshan> PetefromTn_: wow
[04:29:00] <PetefromTn_> yup...one stupid wire.
[04:29:02] <zeeshan> im suprised the power supply didnt go into overcurrent protection
[04:29:05] <PetefromTn_> in the wrong place.
[04:29:15] <PetefromTn_> nope it fried.
[04:29:18] <PetefromTn_> Nice light show.
[04:29:24] <zeeshan> what kind of supply?
[04:29:26] <PetefromTn_> lots of smoke.
[04:29:38] <PetefromTn_> linear supply that came in the machine.
[04:29:41] <zeeshan> ah
[04:29:44] <CaptHindsight> zeeshan: speaking of cars, are there any flashing tools for Nissan ECM's besides the factory consult-II?
[04:29:45] <zeeshan> maybe it didnt have overcurrent protection
[04:29:47] <PetefromTn_> it is a heavy duty little bastard.
[04:30:00] <PetefromTn_> but not heavy duty enough apparently to take that abuse.
[04:30:15] <zeeshan> there is nistune CaptHindsight
[04:30:45] <zeeshan> PetefromTn_: oh well
[04:30:46] <PetefromTn_> Pete from mesa thinks I blew the 3.3v regulator on the 7i77 card and that it might be fixable.
[04:31:03] <CaptHindsight> http://home.exetel.com.au/nds/NDSII/index.php?content=supportedcars found this for tweaking just about evrything except for complete firmware replacement
[04:31:13] <PetefromTn_> I am gonna send it to him so maybe if it is I will have two 5i25/7i77 setups here.
[04:31:28] <zeeshan> CaptHindsight: that seems like a scanner
[04:31:30] <zeeshan> never seen it before
[04:31:39] <PetefromTn_> Then I can do a lathe or something with it.
[04:31:39] <zeeshan> PetefromTn_: you dont need 2

[04:47:26] <zeeshan> and they asked me if i would like to proceed

[05:23:56] <PetefromTn_> I dunno I like the 8" four jaw so yeah an 8 would be nice but the lathe is kinda underpowered for too large a piece.

[08:39:23] <SpeedEvil> The 3-jaw on my lathe is quite accurate.
[08:39:35] <SpeedEvil> Unfortunately, the spindle has a whole degree and a half of bend.
[08:40:04] <SpeedEvil> It was used (not by me) to turn a rather large wooden bowl, and there was an incident.

[14:44:09] <PetefromTn_> Morning folks..
[14:44:27] <zeeshan> hi
[14:44:30] <zeeshan> change your ebay passwords
[14:44:31] <PetefromTn_> Well it has been a very good morning for me here..
[14:44:36] <zeeshan> they got hacked!
[14:45:28] <PetefromTn_> I got the new 7i77 installed and wired up my spindle cooling fan relay, installed all the new relay ice cubes and just got done testing the machine. EVERYTHING WORKS!!! YEAH YIPPEE YEEHAW !!
[14:45:33] <pcw_home> all?
[14:45:45] <zeeshan> pcw_home: according to cnn.com
[14:45:51] <zeeshan> unknown amount got hackewd
[14:45:52] <pcw_home> lovely
[14:45:55] <PetefromTn_> I cannot tell you how happy I am that I did NOT blow any of the new servo drives or spindle drive.
[14:46:20] <zeeshan> nice PetefromTn_!
[14:46:21] <zeeshan> :]
[14:46:50] <PetefromTn_> pcw_home Thanks so much for your help with this screwup I did.
[14:47:08] <PetefromTn_> Now thankfully I can get back to making some parts and some money.
[14:47:53] <PetefromTn_> It was getting to the point where I was gonna have to tell the customers about it and have to turn them away until I could get it fixed.
[14:48:02] <PetefromTn_> But now I am ready to make parts again.
[14:48:07] <pcw_home> NP, I didn't think you would have fired anything except the field I/O section of the 7I77
[14:48:15] <PetefromTn_> I just got thru warming up the spindle
[14:48:21] <pcw_home> s/fired/fried/
[14:48:23] <PetefromTn_> You build that card right man..
[14:48:35] <PetefromTn_> whatever you did it saved my expensive bits.
[14:48:54] <PetefromTn_> I got the new cards in real quick too so I was able to get it fixed quickly.
[14:49:07] <PetefromTn_> could have been a disaster with what I did.
[14:49:26] <PetefromTn_> I removed the old 7i77 card and I want to send it back to you to see if you can fix it like you said.
[14:50:13] -!- dnaleromj [dnaleromj!~dnaleromj@] has joined #linuxcnc
[14:50:16] <PetefromTn_> I looked at it and there do not seem to be any burned spots or any obvious physical damage to the card.
[14:50:37] <PetefromTn_> Hopefully it is just some chip or component you can swap out and be back running again.
[14:50:37] <CaptHindsight> zeeshan: "The database, which was compromised between late February and early March, included eBay customers’ name, encrypted password, email address, physical address, phone number and date of birth." thanks for telling us so soon :)
[14:50:47] <zeeshan> lol
[14:50:51] <zeeshan> ebay is retarded
[14:51:11] <PetefromTn_> huh I have bought several items since that time frame and not had any problems.
[14:51:44] <PetefromTn_> The 24 volt power supply I blew up for one and some tools on ebay in the last two weeks.
[14:51:52] <zeeshan> PetefromTn_: thats the point
[14:51:56] <zeeshan> its a silent attack
[14:52:05] <zeeshan> which doesn't mean you'd know your password was compromised

[17:23:26] <IchGuckLive> ebay HK
[17:23:39] <IchGuckLive> UK -> Germany
[17:23:52] <MrHindsight> USA to Germany parcel post is >30 days
[17:24:13] <IchGuckLive> i got a hint on this seller towards ebay as part stationed and sold from UK HA Ha
[17:24:49] <PetefromTn_> IchGuckLive How am I the man of the day? LOL
[17:25:07] <MrHindsight> the bad side of buying direct from China is they have a misleading ad
[17:25:19] <IchGuckLive> 7i77 in first atampt
[17:25:29] <MrHindsight> the return shipping costs to China from USA are high and slow
[17:26:06] <MrHindsight> so it's common suppliers there to make deals with you if you aren't happy for lower cost items <$50

[17:27:13] <IchGuckLive> thats why they guessing you take even more fault parts
[17:27:29] <IchGuckLive> i got a LM10UU 100 items that whee crap
[17:27:51] <MrHindsight> at least on fleaby you can post negative feedback

[18:03:57] <jt_key_west> hi tom
[18:04:02] <zeeshan> how much backlash exsts in timing pulleys like XL?
[18:04:07] <zeeshan> *exists

[18:04:28] <zeeshan> 15 teeth and 32 teeth
[18:04:30] <zeeshan> w/ a 118 tooth belt
[18:04:31] <archivist> how worn is the pulley and belt
[18:04:34] <jt_key_west> hurricanes are for the fall
[18:04:35] <zeeshan> brand new
[18:04:45] <IchGuckLive> if you can go rack and pinion
[18:04:49] <Tom_itx> JT, ~100 or so expected here
[18:05:02] <Tom_itx> then storms for a few days
[18:05:06] <zeeshan> its on a ball screw.
[18:05:22] <archivist> zeeshan, note the specs are blank on that error when I liiked
[18:05:30] <archivist> looked
[18:05:31] <jt_key_west> It never gets above 90 something here
[18:05:41] <zeeshan> archivist: im looking at images of 'clearances'
[18:05:44] <kfoltman> pcw_home: yeah yeah I know
[18:05:53] <zeeshan> and all these timing belts have abit of clearance
[18:05:58] <zeeshan> so there should be some backlash..
[18:06:01] <IchGuckLive> zeeshan: on ballscrew so why not 20/25
[18:06:08] <jt_key_west> Any storms due in the Midwest sunday?
[18:06:08] <Tom_itx> aren't you supposed to go south when it's February and blizzard weather at home?

[18:07:48] <zeeshan> not what size i need
[18:08:01] <archivist> he never understands the question :(
[18:08:10] <IchGuckLive> no backlash on 180deg in system action
[18:08:25] <zeeshan> what if its 180.5 degrees
[18:08:29] <zeeshan> :P
[18:08:50] <jt_key_west> Well gotta go take a nap.
[18:08:54] <IchGuckLive> below 80deg you got only 3 teeth in action and that will give you a backlash
[18:09:12] <zeeshan> man i shoulda just made a direct drive mount
[18:09:17] <zeeshan> for this stupid x axis
[18:09:21] <zeeshan> stupid pulleys
[18:09:32] <IchGuckLive> pulleys are great
[18:09:33] <zeeshan> just another thing to add back lash
[18:09:39] <jdh> pulleys are great
[18:09:49] <archivist> direct drive also has resolution and accuracy problems
[18:09:54] <IchGuckLive> i use them all the time
[18:10:04] <zeeshan> archivist: i have 5mm pitch lead screws
[18:10:11] <IchGuckLive> better and smoother run and gearing force added
[18:10:11] <zeeshan> and 1/4 stepping
[18:10:16] <jdh> so you ahve crappy res
[18:10:27] <zeeshan> how is that crappy resolution?
[18:10:31] <IchGuckLive> XL is at 5,08mm
[18:10:48] <archivist> what is the gear ratio
[18:10:54] <IchGuckLive> in europ i prefer metric T stuff
[18:10:58] <zeeshan> my Z axis is direct drive
[18:11:16] <zeeshan> the X axis i was planning to run only pulleys because of the placement of the stepper
[18:11:22] <zeeshan> if i mounted it direct, it'd always hit me
[18:11:26] <zeeshan> when i'd work on the machine :P
[18:11:52] <archivist> use some reduction to get a better resolution

[18:12:40] <archivist> I dont care about backlash with unidirectional G code
[18:12:55] <zeeshan> 5 mm pitch = 0.19685"... .19684/200 steps = 0.000984 " resolution
[18:12:59] <zeeshan> and its 1/4 step
[18:13:12] <zeeshan> so 0.000984 / 4 = 0.0002" resolution
[18:13:15] <zeeshan> thats plenty for direct drive
[18:13:18] -!- jt_key_west has quit [Ping timeout: 240 seconds]
[18:13:38] <IchGuckLive> so 20/25 timingbelt gives you a exact 400 stepp half steping best precission on max speed
[18:13:39] <zeeshan> so pulleys or direct drive
[18:13:41] <zeeshan> doesnt matter
[18:14:02] <renesis> fuck pulleys
[18:14:06] <Connor> zeeshan: 1/4 step doesn't always guarantee .0002" though.. the stepping can be a little off depending on where it's at on the motor..
[18:14:14] <renesis> ha
[18:14:23] <zeeshan> connor
[18:14:28] <zeeshan> the point is it's less than 1 thou
[18:14:30] <renesis> theres jitter but its not like its going to be way the fuck off
[18:14:35] <jdh> radius
[18:14:38] <IchGuckLive> im off BYE
[18:14:40] <Connor> with that being said, I think I do 1/8 stepping and all mine are direct drive.

[18:14:46] <renesis> i dont really consider my microsteps as resolution
[18:14:52] <renesis> just makes the machine run smoother
[18:15:06] <zeeshan> renesis: well if its 0.0009 without microstepping
[18:15:16] <zeeshan> you can expect it to be less than 0.0009 with microstepping
[18:15:19] <zeeshan> which is all i want
[18:15:20] <renesis> are you running geckos?
[18:15:22] <zeeshan> no
[18:15:29] <zeeshan> kl8070d automtiontechnologies drives
[18:15:40] <archivist> longshine then :)
[18:15:43] <renesis> right so the machine has to push all the steps
[18:15:53] <renesis> i think geckos like, microstep to the next full step?
[18:15:54] <jdh> it's a 34 motor?
[18:15:56] <zeeshan> i mean from the video i did yesterday night
[18:15:59] <pcw_home> long may they shine
[18:16:00] <zeeshan> when i commanded 1 thou
[18:16:01] <zeeshan> it moved 1 thou
[18:16:02] <renesis> er
[18:16:05] <zeeshan> all the way to 5 thou
[18:16:08] <zeeshan> yea jdh
[18:16:09] <renesis> the controller has to push all the steps
[18:16:41] <renesis> my xyolotex is the same, i have 200 steps motors on 20 pitch, i dont consider my resolution better than .00025
[18:17:20] <renesis> even when im technically stepping at .000063 quarter stepping
[18:17:30] <zeeshan> why not?
[18:17:39] <zeeshan> i mean if youre microstepping that much
[18:17:46] <renesis> it just keeps the steppers from sounding like theyre going to asplode from excitement during curves
[18:17:49] <zeeshan> theres no way its going to jitter by 0.0025"
[18:17:56] <zeeshan> er
[18:17:58] <zeeshan> 0.00025

[18:17:59] <renesis> right but its going to jitter
[18:18:04] <zeeshan> yes
[18:18:10] <zeeshan> but not to 0.00025
[18:18:10] <jdh> I do 20k microstepping on parkers
[18:18:11] <renesis> and theres so much other slack in the machine
[18:18:12] <zeeshan> maybe less than that
[18:18:26] <renesis> i dont really think of anything below .00025 existing on my machine
[18:18:39] <archivist> zeeshan, you should have a read of http://www.micromo.com/microstepping-myths-and-realities.aspx
[18:18:45] <renesis> jdh: steppers or brushless?
[18:18:57] <jdh> parker steppers
[18:19:02] <renesis> like, if it didnt *sound* better, i wouldnt microstep
[18:19:10] <renesis> because of the load on the controller
[18:19:22] <renesis> id rather rapid faster
[18:19:28] <jdh> that's the default setting for the drives
[18:19:32] <renesis> tho geckos i dont think would have the same issue
[18:19:36] <zeeshan> archivist: let me clarify this 100%.
[18:19:47] <renesis> jdh: so its basically analog
[18:20:03] <pcw_home> step motors have spring just line every other motion component (1/200th rev to max torque)
[18:20:09] <jdh> I guess. basically pricey and works well
[18:20:11] <pcw_home> just like
[18:20:22] <renesis> yeah i bet
[18:20:22] <zeeshan> if a non-stepped system gives a resolution of 0.001", by microstepping at for example 1/4 microstep, i could expect better than 0.001" resolution
[18:20:27] <zeeshan> what that resolution is, is unknown
[18:20:33] <zeeshan> but i can confidentally say it's better than 0.001"
[18:20:40] <zeeshan> truth or am i completely wrong?
[18:20:41] <zeeshan> :P
[18:20:46] <pcw_home> Depending on load
[18:20:48] <archivist> zeeshan, I actually checked mine :)
[18:20:52] <renesis> anything off the .001 steps is going to be more prone to jitter
[18:21:02] <renesis> it depends a lot on the circuits
[18:21:35] <renesis> like, is it current feedback or just dumb pwm, is it high slew rate or does it bog down at high step rates, etc etc
[18:21:40] <zeeshan> pcw_home: assuming that the motor isn't losing steps
[18:21:48] <zeeshan> due to overdemanding it
[18:22:04] <pcw_home> If you lose steps all is lost...
[18:22:05] <renesis> i think microstepping youre less likely to lose steps
[18:22:06] <archivist> missing steps is a complete failure, should never happen
[18:22:22] <renesis> thats why i use it, its smoothly hands off the coils
[18:22:33] <renesis> you hear the improvement
[18:22:47] <pcw_home> yes microstepping results in less resonance/noise
[18:22:52] <renesis> but in between steps, i dont consider it a rigid hold
[18:22:55] <renesis> its basically floating
[18:23:10] <archivist> but on 8th steps here I can hear the magnetic error
[18:23:19] <pcw_home> no, its a spring
[18:23:23] <renesis> right i dont 8th step on my xylotex anymore
[18:23:32] <zeeshan> honestly, just with direct drive on my Z axis i have 0.0009 theoretical resolution, without any microstepping
[18:23:43] <zeeshan> but .0009 in the X direction would be unacceptable
[18:23:54] <zeeshan> cause its out by 0.002 in the diameter.
[18:24:05] <zeeshan> so i guess a 2:1 pulley is necessary
[18:24:09] <renesis> you have 200 step motors already?
[18:24:17] <zeeshan> renesis: dieeee
[18:24:17] <renesis> fuck a pulley, its a CNC
[18:24:19] <zeeshan> watch my video

[18:28:59] <zeeshan> i moved in the same direction
[18:29:07] <zeeshan> ??

[18:29:21] <renesis> because something was stuck the first step
[18:29:32] <zeeshan> screw you guys
[18:29:33] <renesis> then broke free and shifted to the other side of a nut

[18:33:53] <zeeshan> and just do anti-backlash nuts on it
[18:33:57] <zeeshan> save some money and headache :p
[18:34:54] <renesis> zeeshan: lab at new school has three haas mills and a haas lathe
[18:35:20] <zeeshan> nice
[18:35:25] <renesis> and it seems the lathe is mostly not dead yet
[18:36:26] <renesis> also they have a fuck ton of large envelope injection mold and vacuum form machines
[18:36:44] <renesis> they were making walnut shell composite shooting clays when i visited, heh

[19:31:52] <skroon> hi all
[19:32:14] <skroon> anybody know what kind of machine this is ? http://www.formit.nl/img/content/IMG_4060.jpg table saw or something?
[19:33:24] <archivist> is it grinding or moving the plastic
[19:34:18] <skroon> grinding i think
[19:34:25] <skroon> they idea is to make a v-grove
[19:34:37] <skroon> but i've never seen these types of "wheels" on table saws, so i'm not sure what type of machine it is
[19:34:57] <archivist> looks special for the job
[19:36:41] <skroon> i've seen them more, where they have CNC thermo bending machines (for plastics)
[19:36:53] <skroon> they use this v-groove where the bend needs to be
[19:37:03] <witnit> looks like someone decided to use this wheel to drive the part at a constant feed rate, on something very similar to a router
[19:38:02] <archivist> skroon, I have seen a plastic box maker use that sort of groove for the bends
[19:38:21] <skroon> archivist: right, plastic box makers :-) that's also what i'm trying todo
[19:38:33] <skroon> witnit: ah right, might well be indeed
[19:39:37] <skroon> archivist: i'm using my cnc to make the 2d pattern, and then would like to thermo bend
[19:40:00] <witnit> I think if you needed to make one, a dc speed controller and gearbox would be simple enough to duplicate the machine
[19:40:23] <archivist> hot air gun
[19:41:19] <skroon> witnit: good idea indeed
[19:42:43] <witnit> I wonder if you could do plastic bending by heating your plastic with a fast panning laser beam
[19:42:49] <witnit> accurate heating area or something
[19:44:15] <archivist> skroon, http://www.boss-enclosures.co.uk/customdesign/Steps_and_Principles they did it, they also use rectangular grooves for fitting parts together
[19:46:42] <skroon> archivist: awesome!
