[00:00:45] <JT-Shop> emcrules_w700: you might have to get with Dewey on that one
[00:01:13] <JT-Shop> that's going to be bad ass http://imagebin.org/183554
[00:03:13] <emcrules_w700> JT-Shop: just tried it it works fine
[00:04:00] <andypugh> 11/11/11 here as of 3 mins ago
[00:04:40] <andypugh> The last date with only 1s and 0s in it that any of us will see.
[00:05:02] <emcrules_w700> thats in five hours for me. A special day to remember all of our brave vetrans!!!!
[00:05:32] <andypugh> And the non-brave ones who died anyway.
[00:06:02] <emcrules_w700> well said
[00:06:55] <emcrules_w700> JT-Shop: what is that an ACME slingshot
[00:08:45] <PCW> OK no more segv, now to test with resolver
[00:09:29] <andypugh> JT-Shop: Are you sure that the shackles are beefy enough?
[00:09:39] <syyl_> that kind of crossbow was used by the coyote to catch the roadrunner...
[00:09:46] <JT-Shop> andypugh: yea they will hold fine
[00:09:50] <syyl_> everyone knows what happened to him ;)
[00:10:17] <JT-Shop> it is a ballista with a twist... using truck spring instead of the torsion box
[00:10:29] <andypugh> JT-Shop: There are going to be immense forces when the cable goes straight
[00:10:53] <JT-Shop> yep
[00:11:31] <JT-Shop> we won't shoulder fire it the first few times for sure
[00:12:14] <andypugh> Talking of which (and 11/11/11) http://www.bbc.co.uk/news/magazine-15652440
[00:12:19] <JT-Shop> the cable clips will hold till the cable almost breaks... maybe more
[00:12:52] <andypugh> I am happy with the clips, it's the spring-shackle equivalents.
[00:13:25] <andypugh> I bet you a beer that they straighten themselves out.
[00:13:39] <JT-Shop> that I won't bet on :)
[00:13:58] <Nick001-Shop> JT-Shop-What servo amps are you using with the mesa cards on the hardinge?
[00:13:59] <JT-Shop> if they do a bit, it won't be a show stopper
[00:14:13] <JT-Shop> the ones that came on the CHNC
[00:14:36] <Nick001-Shop> are you using the tachs?
[00:14:58] <JT-Shop> yep, you have to AFAIK
[00:15:08] <JT-Shop> unless your cradek
[00:15:49] <JT-Shop> I just plugged into the velocity input on the drive and tied the encoder back to the 7i33
[00:15:56] <Nick001-Shop> I'm trying to rid of them as they give me a prob and what did cradek do
[00:16:43] <JT-Shop> you have a HNC like Danimal_garage and cradek?
[00:17:54] <Nick001-Shop> i think so hardinge HCNC with an allen bradly CNC control
[00:18:24] <JT-Shop> mine had the General Numeric control with Fanuc drives
[00:18:49] -!- Loetmichel has quit [Ping timeout: 260 seconds]
[00:19:05] <Nick001-Shop> totally different than mine GE servo amps
[00:19:26] <skunkKandT> Nick001-Shop: if you have enough extra dacs - you can output a simulated tach signal and send it to the amps
[00:19:32] <Danimal_garage> JT-Shop: exact same machine as cradek
[00:20:03] <Nick001-Shop> how do I get extra dacs
[00:20:17] <Danimal_garage> mine had GE HIAK amps
[00:20:19] <skunkKandT> money.. ;)
[00:20:22] <Danimal_garage> ha
[00:20:41] <skunkKandT> you are using the picosystems stuff aren't you?
[00:21:15] <Danimal_garage> yes
[00:21:23] <skunkKandT> then I don't know.. (I only am familiar with mesa)
[00:21:24] <Danimal_garage> just the resolver boards
[00:21:33] <skunkKandT> I meant Nick001-Shop
[00:21:37] <Danimal_garage> oh
[00:21:50] <Danimal_garage> well i like to hear myself type so...
[00:21:52] <skunkKandT> how do you like the resolver converters?
[00:21:54] <Nick001-Shop> right using pico for now
[00:22:15] <Valen> nano FTW!
[00:22:32] <skunkKandT> I have a 7i33 and 7i48 for my 'build' so I have 10 dacs ;)
[00:22:44] <Danimal_garage> they work
[00:22:50] <Danimal_garage> just too expensive
[00:22:50] <JT-Shop> I'm surprised at how far I can draw the ballista back by hand
[00:22:52] <skunkKandT> still have a couple left over.. I may get rid of all my tachs (down to 2)
[00:22:58] <Nick001-Shop> mesa has 1 resolver card for $69.00 vs 450 for the pco cards
[00:23:16] -!- Loetmichel [Loetmichel!Cylly@p54B13FDC.dip.t-dialin.net] has joined #emc
[00:23:30] <skunkKandT> mesa has really done some cool things.. And I have not had the hardware hickup once
[00:23:54] <skunkKandT> and my setup is not for the faint of heart
[00:24:03] <Valen> they just need a high amperage medium voltage controller
[00:24:17] <skunkKandT> Valen: amc drives...
[00:24:23] <Valen> url?
[00:24:27] <skunkKandT> ebay
[00:24:31] <skunkKandT> ;)
[00:25:31] <andypugh> Nick001-Shop: Which board is that?
[00:26:13] <Nick001-Shop> I saw the mesa had a 4 resolver card
[00:26:34] <andypugh> There is the 7i49 6-resolver card, but that is $184
[00:27:00] <Nick001-Shop> still cheaper than 450 for pico
[00:27:24] <Nick001-Shop> just have to do something about the servo amps
[00:27:44] <andypugh> It also needs an FPGA card, whereas Pico is standalong
[00:28:07] <emcrules_w700> http://ontario.kijiji.ca/c-ViewAd?AdId=328874116&MessageId=MSG.VIEW_AD.REPLY_TO_AD_SENT&mpname=R2S&mpname=Activity-R2S&mpuid=80014%3B145%3B328874116%3B-1677519194%3B%3B&secev=AQAAATOKxiAAAM0AAAACACIxMzM5MDA0ZGJjYS5hMjBiMjZkLjYwM2E2LmZmZmZmNGNjAAAAABOaOIQBAAAAAgAAAABZaC8AgDh13z5eDWn9kp%2FN32r2tROUQAg*
[00:28:20] <emcrules_w700> what do you guys think^
[00:28:43] <JT-Shop> I never click on a link that long
[00:28:51] <andypugh> Cute
[00:29:19] <Nick001-Shop> I'll get anything that will work
[00:29:40] <emcrules_w700> http://ontario.kijiji.ca/c-buy-and-sell-business-industrial-CNC-Kitamura-my-center-0-W0QQAdIdZ328874116
[00:30:50] -!- karlkec_ has quit [Quit: Ex-Chat]
[00:30:53] <andypugh> I do try to be completely impartial between Pico and Mesa. it's hard because I know nothing much about Pico
[00:31:35] <JT-Shop> me too
[00:31:40] <andypugh> Ballscrews are not as expensive as people think
[00:32:22] <andypugh> But you are probably looking at $500 to get than machine working if the screws are useless or missing.
[00:32:32] * JT-Shop starts working on ballista trigger parts
[00:34:02] * Tom_itx demands updated pics
[00:34:23] <emcrules_w700> Yeah the worn ball screws dont scare me
[00:35:01] <emcrules_w700> you would be amazed how hard it is to find a small VMC for a steal.
[00:35:16] <Nick001-Shop> the pico board is having hiccups and I'd like to go back to the resolvers rathe than the encoders.Just need to do something about the servo amps. would rutex amps work with mesa?
[00:36:43] <emcrules_w700> Nick001-Shop: i use teco amps and they work great with mesa.
[00:37:38] <andypugh> Nick001-Shop: Have you looked at the Mesa amps?
[00:38:03] <JT-Shop> JT-Shop that's going to be bad ass http://imagebin.org/183554
[00:38:03] <andypugh> What tyoe of motor are they?
[00:38:38] <Nick001-Shop> Where are they
[00:39:22] <Nick001-Shop> I didnt see them on their site-mesa
[00:39:24] <andypugh> http://www.mesanet.com/ (look under "motion control")

[00:40:20] <skunkKandT> it is evil.. ;)
[00:40:38] <skunkKandT> (unless you have steppers)
[00:40:47] <JT-Shop> from an evil mind...
[00:40:56] <andypugh> Things like a dual 2kW H-bridge driver (ie for two motors) for $300 which plugs straight into the FPGA card
[00:41:06] <Nick001-Shop> all servos that came with the machine
[00:42:17] <andypugh> Right, logging off time.

[00:54:54] <skunkKandT> everyone is leaving
[01:02:27] <Danimal_garage> i'm still here
[01:02:32] <skunkKandT> :)
[01:02:44] <Danimal_garage> just made an offer on a vfd on ebay for the new mill
[01:02:55] <skunkKandT> new mill?
[01:02:59] <Danimal_garage> yea
[01:03:07] <Danimal_garage> got another mill coming
[01:03:16] <skunkKandT> what is it?
[01:03:29] <Danimal_garage> some japanese knee mill just like my shizuoka
[01:03:38] <Danimal_garage> kasoga or something
[01:03:48] <skunkKandT> heh - cool
[01:03:51] <Danimal_garage> it's got a bandit control on it now
[01:03:57] <Danimal_garage> bandit 3
[01:04:04] <skunkKandT> I have only seen bandits on plasmas
[01:04:12] <skunkKandT> interesting
[01:04:19] <Danimal_garage> my shizuoka had a bandit 1
[01:04:24] <skunkKandT> huh
[01:04:39] <Danimal_garage> they both have the same toolchangers on them
[01:04:58] <Danimal_garage> so i can use the same ladder
[01:05:02] <skunkKandT> neat - all set then
[01:05:06] <Danimal_garage> yea
[01:05:13] <Danimal_garage> it's already got servos on it
[01:05:24] <skunkKandT> did the bandit 1 have steppers?
[01:05:27] <Danimal_garage> yes
[01:05:51] <Danimal_garage> it's a working machine but i'll probably still emc it
[01:05:52] <Valen> thinking of getting my dad a camera for the shed to take photos of mills and such
[01:06:13] <Valen> http://www.ebay.com.au/itm/Canon-PowerShot-A450-5-0-MP-Digital-Camera-Silver-/320789171208?pt=AU_Digital_Cameras&hash=item4ab0864c08#ht_500wt_1413 what you think?
[01:06:21] <Danimal_garage> Valen: i got a decent olympus SLR pretty cheap on ebay
[01:06:52] <Danimal_garage> that seems like a good deal
[01:06:58] <Danimal_garage> cannon has decent cameras
[01:08:03] <Danimal_garage> skunkKandT: the only unknown is if the mill has encoders or resolvers
[01:08:16] <Danimal_garage> i think it's new enough to have encoders but we'll see
[01:08:16] <Valen> Danimal_garage: probably a fair bit more than $40 delivered though?
[01:08:21] <skunkKandT> I bet it is encoders
[01:08:59] <Danimal_garage> Valen: yea, i havent looked at prices lately, how much are they new?
[01:09:20] <Danimal_garage> skunkKandT: i hope so, i already have the mesa card for that
[01:09:59] <Danimal_garage> the only thing is the cover for the resolver/encoder is pretty big
[01:10:09] <skunkKandT> I love canon
[01:10:12] <Danimal_garage> it's sort of the shape of a resolver
[01:10:13] <Valen> dunno i have a budget of around $40 for it ;->
[01:10:32] <Valen> reviews of it seem mixed

[01:12:16] <skunkKandT> I don't know our exact model.. it is a bit newer than that
[01:12:48] <skunkKandT> I have always had bad luck with cameras. this is the first one I am 100% happy with
[01:13:14] <skunkKandT> the battery lasts forever.. Takes great photos and videos.

[01:14:05] <jdhNC> I've had 4 different canon powershots, they were all good (for their price range anyway)
[01:14:13] <skunkKandT> Think it is an elph
[01:14:29] <Valen> oh well it'll probably be better than even a modern phone camera
[01:14:42] <skunkKandT> similar to http://www.ebay.com.au/ctg/Canon-IXUS-220-HS-300-HS-Digital-ELPH-12-1-MP-Digital-Camera-Red-/109826025?_dmpt=AU_Digital_Cameras&_pcategid=166899&_pcatid=100&_refkw=canon+powershot+elph&_trkparms=65%253A12%257C66%253A2%257C39%253A1%257C72%253A5520&_trksid=p3286.c0.m14

[01:18:10] <Danimal_garage> sweet, i just won the VFD
[01:18:29] <Danimal_garage> 5hp mitsubishi vfd for $75, not too bad
[01:18:43] <Danimal_garage> same one as i have now on my other mill, just slightly newer
[01:19:27] <tom3p> will you be buying new motor or use whats on the BP cone?

[01:19:58] <skunkKandT> heh tosvert?
[01:20:26] <skunkKandT> we have a 5hp toshiba on the K&T from the mid 90's
[01:20:35] <skunkKandT> still going strong (knock on wood)
[01:22:48] <tom3p> what does it drive? a std 1800/3600rpm ac motor? a special spindle motor with high rpm?
[01:23:02] <Danimal_garage> standard ac motor
[01:23:09] <Danimal_garage> it's not a BP clone
[01:23:10] <Jymmm> Miss Daisy
[01:23:17] <Danimal_garage> it makes a BP look like a toy
[01:23:41] <tom3p> so you got a transmission ( and gears ?) no offense, the knee mill
[01:23:54] <Danimal_garage> i'll be leaving the motor on it
[01:24:10] <Danimal_garage> yea it's got gears and pulleys
[01:24:23] <Danimal_garage> but i'll just make it a fixed rpm and control it with the vfd
[01:24:41] <Danimal_garage> i only use between 1700rpm and 6000rpm
[01:24:47] <Danimal_garage> all smaller tools
[01:24:51] <tom3p> ah, wondered about the range
[01:25:28] <Danimal_garage> i have my current mill slightly underdriven, and i run the motor at 120hz to get to 6k
[01:25:40] <Danimal_garage> although it cuts at lower speeds with no issue
[01:25:57] <tom3p> like 400hz tops?
[01:26:14] <Danimal_garage> and no offense taken, i do actually have a BP exact clone for a manual mill :)
[01:26:19] <Danimal_garage> 120hz tops
[01:26:31] <Danimal_garage> 1700rpm motor
[01:26:41] <Danimal_garage> 3400rpm is still ok for the bearings
[01:27:11] <Danimal_garage> 120hz=6krpm on my mill
[01:27:40] <Danimal_garage> 30hz is 1500rpm
[01:28:09] <skunkKandT> we run our 1800rpm motor at the max of 4000ish rpm
[01:28:10] <Danimal_garage> the new mill will be the same
[01:28:28] <Danimal_garage> nice
[01:28:37] <tom3p> the VFD goes higher? (thats what i meant by 400hz)
[01:28:50] <Danimal_garage> tom3p: i have no clue how high it goes
[01:28:51] <tom3p> skunkKandT, thats very good to now, thx
[01:28:56] <tom3p> know
[01:29:01] <Danimal_garage> all i know is it'll do at least 120hz
[01:29:57] <tom3p> skunkKandT, would you guess a 3400rpm motor might go 2x also? like near 8k?
[01:30:18] <Danimal_garage> tom3p: yes
[01:30:30] <Danimal_garage> i have it like that on my manual mill
[01:30:55] <tom3p> great, thx, that gives me some options! my machine will be doing tiny stuff
[01:30:58] <Danimal_garage> i have a 2 speed motor on my manual mill, and i run it at 120hz sometimes
[01:31:10] <skunkKandT> tom3p: I don't know.. I might test it first... in a cage.. ;)
[01:31:15] <Danimal_garage> haha
[01:31:25] <tom3p> :)
[01:31:27] <Danimal_garage> tom3p: i wouldnt run it very long that high
[01:31:39] <Danimal_garage> bearings would be the issue
[01:31:42] <Danimal_garage> and balancing
[01:31:50] <skunkKandT> we actally tested our motor for the K&t by running it at 2X+ rpm for a while. (bearing heat and such)
[01:32:36] <Danimal_garage> i'm pretty disapointed that i couldnt fit a vmc in here
[01:32:38] <skunkKandT> right now it is only running at 1120rpm.. spindle running at 600rpm
[01:32:45] <Danimal_garage> but at least i'll have a second mill
[01:32:49] <Valen> if its not overheating, running it faster will make the bearings wear out faster but eh, is that really an issue?
[01:33:00] <skunkKandT> right
[01:33:17] <tom3p> yeah, good to know theres some headroom, (keep spare bearings at hand)
[01:33:19] <Valen> untill the copper flies out of the windings or something anyway ;->
[01:33:45] <Valen> if you can buy the bearings at your leisure you'll save $$$
[01:34:15] <Valen> vxb or ebay ;->
[01:36:50] <tom3p> i was surprised at the cost of the small spindles, like keling... 360$+vfd for 1.5kw ER11 water cooled
[01:37:06] <Tom_itx> i just ordered from vxb with good results. quick shipping
[01:37:08] <tom3p> it was near 3k$ for soemthing that was toolchangeable

[01:37:48] <Valen> we got a 3Kw from ebay with VFD for ~$400 or so
[01:38:27] <Valen> Tom_itx: how is the kwality?
[01:38:44] <Tom_itx> seems pretty good
[01:38:45] <Danimal_garage> i heart toolchangers
[01:38:54] <Valen> we want a toolchanger :-<
[01:38:54] <Tom_itx> i got these to fix a washing machine :)
[01:39:12] <Tom_itx> ordered SS for better wear
[01:39:17] <Tom_itx> in the app
[01:39:29] <Tom_itx> so they were a bit higher
[01:39:33] <Valen> probably get ceramic for the same price as if you got regular ones locally ;->
[01:40:07] <Tom_itx> have you ordered from them?
[01:40:22] <Valen> no but they are really cheap
[01:40:35] <Tom_itx> i'm not familiar with ceramic
[01:40:43] <Tom_itx> i'm sure they're good
[01:40:52] <Valen> a friend got some bearings for his little motorbike (pocket bike) but they died after a race (regular steel bearings)
[01:40:57] <Tom_itx> but where would you most likely use them?
[01:41:12] <Valen> high speed, high temperature stuff i presume
[01:41:21] <Tom_itx> jet engines?
[01:41:33] <Valen> they use weird stuff
[01:41:41] <Valen> things like dental drills and such like
[01:41:45] <Tom_itx> oh
[01:41:54] <Tom_itx> spindle heads?
[01:42:04] <Valen> i think i have heard of them for high end stuff
[01:42:14] <Valen> but i'm not sure what their shock loading is like
[01:42:14] <Tom_itx> not cheap
[01:43:22] <Valen> no
[01:43:35] <Tom_itx> you can specify brand too i believe
[01:43:42] <Tom_itx> i see several brands listed
[01:43:51] <Valen> you don't want to know what they cost from a "reputable" bearing supplier ;->

[18:45:51] <IchGucksLive> andypugh: thanks but there is alot of vat and more to bring these to Germany
[18:46:01] <Danimal_garage> 5hp mitsubishi, same as the drive on my other mill, just a little newer
[18:46:17] <andypugh> That's an inclusibe price, within the EU, there should be no VAT to pay.
[18:47:01] <andypugh> Sorry, no it isn't It adds up to almost exactly €49 when I try a checkout..
[18:47:02] <Danimal_garage> now i just need to find out if the mill has resolvers or servos

[19:00:19] <mrsun> would be a nice replacement for the screws on the micromill =)

[19:18:17] <JT-Shop> any ideas "So the saga continues…. The problem is related to either software or the Mesa Boards not the computer hardware. We all of a sudden started to have the similar issues with another computer. Maybe something with EMC and Ubunto isn’t jiving?? The other option which seems unlikely is the USB drive that we’ve been using to transfer the files from our CAD/CAM computer to the EMC...
[19:18:19] <JT-Shop> ...computer. One employee thinks it has a virus. It’s really strange. Yesterday it was looking good then we had to make a slight ini change. We tried to open the ini file and it wouldn’t open. We just got a blank screen. After that the computer froze up and we had to pull the plug (literally) to shut it down.
[19:18:21] <JT-Shop> Do you have any idea why the system would keep losing the G54 and G55 touch off settings? It seems that whenever we have issues this also happens. We keep having to reset them. "

[19:22:03] <A2Sheds> run memtest for a few hours
[19:22:53] <JT-Shop> he ran memtest tested the hard drive etc and all reported clean on the Foxcon. This current computer is an older one he was using before getting the Foxcon
[19:22:54] <cradek> I'm picturing them just shutting off the computer with emc still running. this would cause offsets to not be saved.

[21:43:24] <andypugh> I am completely baffled. Someone on CNC zone is trying to use my bldc component to spin a fanuc motor using a normal hal-sensor bldc drive. With the 4 position bits netted to the parport they all go true (on my machine) but that comes out at the wrong angle. If I unlink the pins from the parport then they all change state, but the angle doesn't change. Until I have them _all_ unlinked, when it starts to work, and I can setp t
[21:43:25] <andypugh> input pins and get angles out. That makes no sense at all.
[21:44:54] <JT-Shop> makes even less sense to me
[21:48:00] <andypugh> Well, imagine that the pattern of 4 bits corresponds to an angle, and as the bit values change, the angle should. While any of the bits are netted to the parport, the angle is fixed, regardless of the bit values. Once they are _all_ disonnected, then changing their values has the expected effect.
[21:48:33] <andypugh> I have an inkling what the problem might be.

[22:09:38] <andypugh> The issue seems to be (and I am checking) that the parallel port pins are not numerically 0 or 1, they are numerically 0 or their bit position.
[22:11:38] <JT-Shop> that is interesting
[22:14:47] <cradek> and entirely normal
[22:15:07] <cradek> for digital pins you must test them with if(pin) or if(!pin)

[22:15:26] <cradek> if you write if(pin==1) you're doomed
[22:15:41] <cradek> (you are not the first or last to write that bug)
[22:16:00] <andypugh> The problem was v = pin1 | pin2 << 1 | pin3 << 2 | pin4 << 3
[22:16:36] <andypugh> I am of the opinion that it could be considered a bug in hal_parport.
[22:17:11] <mhaberler> andypugh: the complaint department is, in fact, manned: http://mah.priv.at/gallery2/main.php?g2_view=core.DownloadItem&g2_itemId=35617
[22:17:45] <cradek> andypugh: that's how hal pins work. it's a mistake to think it's particular to hal_parport.
[22:18:05] <cradek> you need to treat them as C booleans (zero for false, or nonzero for true)
[22:18:13] <andypugh> But it isn't how C logic in general works, is it? TRUE == 1?
[22:18:26] <cradek> no, C does not work that way
[22:18:54] <cradek> if(a) {body} executes body if a is nonzero
[22:19:08] <cradek> if(!a) ... zero
[22:19:24] <andypugh> Yes, but (3 == 3) evaluates, reliably, as 1?
[22:19:35] <cradek> yes
[22:19:54] <cradek> (but irrelavent)

[23:46:36] <Danimal_garage> it would be perfect
[23:46:38] <andypugh> If you put in on wheels, it will move.
[23:46:47] <Danimal_garage> it has wheel locks
[23:46:54] <Danimal_garage> it aint moving anyways
[23:46:57] <andypugh> But if you can't lift it high enough, there is no solution.
[23:47:18] <Danimal_garage> which is the problem lol
[23:47:55] <Danimal_garage> it only needs to be hoisted about 6" or so
[23:48:09] <andypugh> You could probably rent a big engine-hoist.
[23:48:25] <Danimal_garage> i have one, but i don't think it's tall enough
[23:48:43] <andypugh> Stand that on blocks?
[23:48:49] <Danimal_garage> it's partially broken too, i need to reweld some stuff on it
[23:48:58] <Danimal_garage> hmm
[23:49:02] <Danimal_garage> hood idea
[23:49:21] <Danimal_garage> it's not like it has to move when the compressor is lifted
[23:49:48] <Danimal_garage> that's a nice little mill btw
[23:49:59] <Danimal_garage> ballscrews?
[23:50:28] <andypugh> It is getting ballscrews
[23:50:43] <andypugh> (It has two so far). It's a slow-moving project
[23:51:17] <Danimal_garage> cool
[23:51:20] <Danimal_garage> servo?
[23:52:02] <Danimal_garage> it would be cool with a high speed spindle and toolchanger
[23:52:03] <andypugh> Yes. I actually only bought it because I found myself with 3 servos and 2x 8i20 going spare :-)
[23:52:14] <Danimal_garage> ha nice
[23:52:19] <Danimal_garage> what size servos?
[23:52:26] <andypugh> 500W
[23:52:37] <Danimal_garage> a little small, aint it?
[23:53:12] <Danimal_garage> gear reduction?
[23:53:32] <andypugh> https://picasaweb.google.com/108164504656404380542/Gibbs#5630434064687887650
[23:54:05] <Danimal_garage> gear box on them?
[23:54:06] <andypugh> and https://picasaweb.google.com/108164504656404380542/Gibbs#5648298973355550482
[23:54:22] <andypugh> No. But they are 7Nm
[23:54:38] <Danimal_garage> cool
[23:55:05] <Danimal_garage> 7??
[23:55:13] <Danimal_garage> hmm
[23:55:18] <andypugh> 500W seems like a big jump from 100W steppers, to me.
[23:55:48] <Danimal_garage> mine are about 5nm, but they're 1.5kw
[23:55:57] <Danimal_garage> something off there?
[23:56:14] <andypugh> I am quoting peak, rated is something like 2.5Nm
[23:56:18] <Danimal_garage> ah
[23:56:42] <Danimal_garage> anything is better than steppers
[23:56:49] <Danimal_garage> has it moved yet?
[23:56:59] <andypugh> As for the hogh-speed spindle, at the moment it is oddly slow speed, low gear is 45 rpm.
[23:57:06] <Danimal_garage> ha wow
[23:57:41] <Danimal_garage> i don't even have a mill that will go as low as twice that speed
[23:58:09] <andypugh> It has been used manually, I am struggling with getting the resolver/arduino/5i33/bldc/8i20 loop all working
[23:58:19] <Danimal_garage> ahh
[23:59:09] <andypugh> I am not sure that the motors don't all have a pole missing, or perhaps the 8i20 has a hysteresis value. Or soemthing.
[23:59:30] <Danimal_garage> that sucks
[23:59:33] <andypugh> But I can't get less than 1/4turn of free play in the motor shafts.
[23:59:53] <Danimal_garage> resolver issue?
