[00:00:21] <andypugh> Ah, yes, here we are: https://sites.google.com/site/manisbutareed/visualizing-emc2-configurations

[00:01:46] <tjb1> Anyone know where I could happen to find this part the wire is connected to?? - http://www.dynatorch.com/images/ohmic1.jpg

[00:04:07] <andypugh> tjb1: Starting point: http://uk.rs-online.com/web/c/?sra=oss&searchTerm=earth+tag&x=0&y=0
[00:04:32] <tjb1> So earth tag is what that is called
[00:04:52] <andypugh> Probably a ground tag where you are
[00:04:53] -!- rob_h has quit [Ping timeout: 265 seconds]
[00:05:42] <andypugh> But it's a conduit gland grounding tag, I think.
[00:06:54] <tjb1> Thanks
[00:07:06] * jdh ponders pointing out the wire is connected to a faston connector
[00:09:28] <andypugh> I chose to answer the question meant, not the question asked.
[00:10:10] <tjb1> http://www.fiatplus.com/grounding-ring-around-sender-pr-289940.html
[00:10:15] <tjb1> So close
[00:10:55] <andypugh> how many do you need? If it's just one, make it
[00:11:59] <andypugh> 20 minutes with a drill and file. 5 mins if it only needs to work
[00:13:11] <jdh> what's the ID?
[00:15:27] <tjb1> I would have to check but I am guessing around 7/8"
[00:16:06] -!- ctjctj [ctjctj!~cjohnson@c-24-62-5-242.hsd1.nh.comcast.net] has joined #linuxcnc
[00:16:07] <jdh> maybe a big ring connector with a faston crimped in it.
[00:17:04] <tjb1> Like so ? - http://www.ebay.com/itm/Ring-Terminal-Lug-4-0-Wire-7-8-Stud-Tinned-Lot-6-/250510540071#ht_1539wt_1165

[00:17:26] <Connor> jdh: I got the air cylinder for $100.00
[00:17:29] <jdh> that's probably too thick, but like that.
[00:17:34] <jdh> cool
[00:17:45] -!- chron0 [chron0!~chrono@2a01:4f8:140:1ffd:5054:ff:fe7e:4583] has joined #linuxcnc
[00:17:58] <jdh> you can buy that ring connector at an auto parts store
[00:18:36] <Tom_itx> you could cut one from a 2" square block of copper too
[00:18:41] <Tom_itx> your choice
[00:19:53] <jdh> or strip 3" of insulation off the wire, wrap it around, and twist tightly.
[00:22:15] <tjb1> I loaded it into cad and the one for the fiat appears to have a .700 hole diameter
[00:22:42] <tjb1> I cant use the hypertherm ohmic cap...
[00:23:42] <andypugh> Connor: After I deigned one for you? Bah!
[00:24:15] <tjb1> I probably will go with a floating torch so I dont have to rely on the tip/metal conducting
[00:24:21] <Connor> andypugh: I would be happy to build one.. Just don't have time or the materials.. not even sure I could do it with the mini lathe or the mill.
[00:25:00] <andypugh> it did need a lit of threading work (Or welding)
[00:25:34] <linux-cnc-bob> whats whats a good feedrate for MDF cuts on a small mill? 1/8" endmill
[00:25:38] <linux-cnc-bob> and good cutdepth per pass
[00:25:42] <andypugh> The only advantage was that it was the right shape for the job.
[00:26:28] <andypugh> linux-cnc-bob: You normally work from peripheral speed and cut-per-tooth

[00:57:04] <Anon5565> hi andy my name is rick, using release 2.4.6
[00:57:09] <gmagno> argh... drag and drop does not work... (http://gcode.joewalnes.com/) you guys know of any gcode viewer? I dont have linuxcnc on my laptop

[00:57:16] * ReadError cant wait to cut into this new 1/8" piece of g10
[00:57:34] <Anon5565> g10? is for?
[00:57:59] <linux-cnc-bob> its like fiberglass
[00:58:08] <linux-cnc-bob> wrecks milling bits fast
[00:58:18] <ReadError> yea but cuts awesome ;)
[00:58:32] <Anon5565> yeah, glass 10 bar, wear tools for sure
[00:58:34] <ReadError> im only using some cheapo 10$ endmills
[00:58:50] <linux-cnc-bob> probably should use a vacuum too or the dust can get all over the feed screws and rails
[00:58:58] <ReadError> yea i do
[00:59:05] <ReadError> stand there the entire time with it
[00:59:10] <Anon5565> better water, i think
[00:59:18] <linux-cnc-bob> my first milling project is a vacuum attachment :D
[00:59:34] <Anon5565> no good for your health
[00:59:42] <linux-cnc-bob> vacuum is outside
[00:59:59] <Anon5565> ar you doing a frame?
[01:00:05] <linux-cnc-bob> me?
[01:00:15] <Anon5565> yes, bob
[01:00:57] <linux-cnc-bob> I noticed there are 4 threaded holes on the bottom of the spindle, so am making a 1/2" thick MDF plate to bolt to that, and then have a hole in it beside the spindle to attach a vacuum hose
[01:01:33] <linux-cnc-bob> not sure of the best way to orient the vacuum hose by the cutting tool
[01:02:33] <Anon5565> vaccum drag air as a semisphere

[01:49:45] <Tom_itx> no support on the top side
[01:49:56] <cradek> that mount is not anywhere near perfect enough to use a solid coupler
[01:50:07] <cradek> it needs to be about 100% more perfect, or you need a flexy coupler
[01:50:07] <Tom_itx> i flat wouldn't use it
[01:50:26] <tjb1> can anyone open www.pct.edu
[01:50:59] <linux-cnc-bob> no
[01:51:01] <Tom_itx> no
[01:51:17] <linux-cnc-bob> are flexible couplers crap?
[01:51:27] <tjb1> alright, thanks.
[01:51:32] <linux-cnc-bob> i have some aluminum ones with a spiral cut in them that seem pretty good but not sure
[01:53:17] <cradek> those are fine but you have to be sure your motor stalls before they snap
[01:53:29] <cradek> they just have to be chosen carefully
[01:54:56] <r00t4rd3d> i have a flex coupler
[01:55:38] <r00t4rd3d> or maybe it isnt
[01:56:31] <r00t4rd3d> "These couplers will not damage the shaft."
[01:56:35] <r00t4rd3d> my white ass
[01:57:33] <r00t4rd3d> so i need a beefy 23 for my x axis, suggestions?
[01:57:42] <r00t4rd3d> 3A
[01:58:28] <jdh> 1/4" shaft?
[01:58:53] <r00t4rd3d> well i think i am going to replace my coupler with a more flexable one
[01:59:00] <r00t4rd3d> so it dont matter i guess
[01:59:27] <r00t4rd3d> sparkfun -might- warranty my motor

[02:03:58] <jdh> I'd get somethign smaller
[02:04:04] <r00t4rd3d> why
[02:04:16] <Tom_itx> mine are 282 oz
[02:04:26] <Tom_itx> you don't really need one that big i doubt
[02:04:49] <jdh> cheap chinese tb6560 probably won't like 3amps
[02:05:09] <r00t4rd3d> i was running it at 3 already
[02:05:14] <r00t4rd3d> on 2a motors :)
[02:06:42] <r00t4rd3d> all the motors at that place are 3a
[02:07:23] <jdh> some 2.8's
[02:07:28] <r00t4rd3d> i just seen
[02:08:32] <r00t4rd3d> they have a 1.4 too

[02:30:45] <Connor> jdh: You get all your stepper covers wired up and everything?
[02:31:41] <Tom_itx> Connor i got some of those DIN plugs put on my control box
[02:32:00] <Connor> Update your pictures! :)
[02:32:30] <jdh> connor: still need to do the Z. I want to replace the stepper mount and redo the ACB's at the same time so I've put it off.
[02:32:43] <jdh> but, it's 64F in my garage right now.
[02:32:44] <Connor> Ahh
[02:32:45] <Tom_itx> i did
[02:33:19] <Connor> Tom_itx: Sorry. Misread who sent me that. You like those DIN plugs ?

[02:40:24] <Tom_itx> linux-cnc-bob, the coords are stored for G54
[02:40:33] <linux-cnc-bob> ok
[02:40:38] <linux-cnc-bob> i got it back to zero
[02:40:45] <linux-cnc-bob> but still have the G54 showing on the GUI

[02:42:19] <cradek> or http://linuxcnc.org/docs/html/gui/axis.html#_menu_items (in particular, Machine / Zero coordinate system)
[02:42:42] <cradek> if it's showing a G54 line in the preview, you haven't zeroed it

[02:46:24] <Tom_itx> all new wiring too
[02:46:52] <Connor> Looking at this video of you milling out the box.. What are you using a Drill Chuck ?
[02:47:08] <Tom_itx> because i didn't have a collet that size
[02:47:15] <Tom_itx> or one available
[02:47:23] <Tom_itx> it works fine, it's such a light cut
[02:48:15] <Connor> Yea, I just heard that the run out can be bad... and chucks aren't good with side load...
[02:49:38] <Tom_itx> it's a .031" cutter, i think the cutter would break before i'd have to worry about side load

[04:13:35] <jdh> ordered it a couple of weeks ago. I had 5 others, but the sensor was on the side instead of top.
[04:14:00] <Connor> Ah. Does chips or swarf trip it ?
[04:14:24] <jdh> I put some Al chips on it, nothing. Not sure what steel will do
[04:15:27] <jdh> looks like this one was $6. The others were a lot cheaper.
[04:17:20] <Connor> I'll get back to the home and limit switches at some point.. I think playing with the power draw bar is going to be fun.
[04:17:46] <jdh> what size washers and how many?
[04:18:36] <Connor> Right now, just a stack of 6.. Don't remember the size.. I think it's the ones HOSS spec'c out for the manually operated version.. They'll do for testing though.
[04:20:59] <jdh> so, if you just want to mill out a circle profile, what do you do?
[04:21:31] <Connor> You can use the g-code for just a circle.
[04:21:44] <Connor> and calculate the offset for the tool diamater.
[04:22:18] <jdh> yeah, it should be easier than that.

[04:23:08] <Connor> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple_EMC_G-Code_Generators
[04:23:14] <Connor> Maybe Arc Buddy ?
[04:23:29] <jdh> that just gives you the one line
[04:23:49] <Connor> okay, what are you trying to do?
[04:23:59] <jdh> cut a .875 circle
[04:24:26] <Connor> You want the inside of it to be .875, or the a .875 disk ?
[04:24:26] <Jymmm> in what?
[04:24:49] <jdh> inside circle, to mount a switch.
[04:25:02] <jdh> in whatever I mount the switch in. Aluminum or plastic
[04:25:05] <Jymmm> how thick is the material?
[04:25:39] <jdh> it is N inches thick.
[04:25:49] <Jymmm> N is not a number
[04:26:00] <jdh> the number doesn't matter
[04:26:32] <Jymmm> It does if i *WAS* gonna write the code for you.
[04:26:34] <roycroft> if he doesn't know yet what material he'll be using he probably doesn't know the value of N at this point
[04:26:59] <jdh> ahh... I can write the code. It should just be easier than that.
[04:27:09] <roycroft> it is
[04:27:16] <Connor> G2 or G3 is your best bet.
[04:27:22] <roycroft> just buy some software that does it for you :)
[04:27:31] <jdh> Connor: sure, that's teh easy part
[04:27:49] <Connor> What's the hard part?
[04:28:19] <jdh> having to write a program everytime you want to cut a circle.
[04:30:45] <jdh> roycroft: I did buy software that does it. But,it's win* and it seems silly to have to draw a circle in cad, then generate a toolpath for it
[04:33:41] <tjb1> jdh, how do you like the oldhams
[04:34:07] <jdh> they are fine. Better than the lovejoy/spider ones on my router
[04:34:57] <Jymmm> Most switches have notches/grooves to prevent turning in what they're mounted in.
[04:35:35] <jdh> this one is a push/pull e-stop. No flats
[04:35:45] <Connor> jdh: So your wanting a ngcgui
[04:35:56] <Jymmm> no 1/8" groove in it?
[04:36:00] <jdh> Connor: that would be fine.
[04:36:28] <jdh> I don't recall one. I think it is actually a metric size.
[04:36:58] <Jymmm> 22mm
[04:37:20] <jdh> Connor: I tried using the array of circles thing, but it didn't seem to handle tool diameter.
[04:38:46] <Connor> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?G12-13
[04:40:15] <Connor> http://wiki.linuxcnc.org/uploads/circular_spiral_pocket_subroutine.ngc
[04:40:18] <Connor> from that.. #3..
[04:40:34] <Connor> looks like a ngcgui script..
[04:41:27] <jdh> no tool diameter compensation
[04:41:49] <Connor> You sure?
[04:41:57] <jdh> no
[04:42:11] <Connor> I think you enter T# command
[04:42:16] <Connor> followed by.. M something..
[04:42:32] <jdh> m6
[04:42:41] <jdh> but that is for g41/g42
[04:43:05] <jdh> this looks like it calculates how far inside to cut based on tool diameter (without usinjg g41/g42)
[04:43:20] <jdh> so, that's pretty close. Just want a profile, but...

[05:32:38] <plasmator> question - what's the best way to set things up to replicate multiples out of the same stock on a mill? Do I do it in CAM? In the controller? ???
[05:33:30] <WillenCMD> To repeat the same program?
[05:34:36] <plasmator> basically, at different places
[05:34:48] <plasmator> I have a program that's output from MasterCAM, for one part
[05:35:41] <plasmator> but I want 4 of that part :)
[05:36:02] <WillenCMD> i would think a macro would be the easiest solution
[05:36:26] <WillenCMD> use different work zones for the locations
[05:38:09] <WillenCMD> solid cam will set that up for you, i don't know about mastercam
[05:39:01] <plasmator> hm, I guess I'll have to do some more googling
[05:39:19] <plasmator> kind of an awkward thing to google, keep getting oddball results :)
[05:45:33] <plasmator> looks like "Transform Tool Paths" is the trick in MasterCAM
[05:48:16] <ktchk> linuxcnc can shift x or y position and touchup to new g54 and do another mill.
[05:53:57] <plasmator> I think that is the thing to do if you have multiple vises/fixtures
[05:54:30] <plasmator> For multiples, in say a 2d sort of operation, I think the Transform Tool Path is the way to go
[05:54:59] <plasmator> took me just a few clicks :)
[05:57:38] <plasmator> thanks all

[16:42:23] <cncjerry> this thing ran like a champ for years on the old version
[16:42:37] <cncjerry> no, don't feel like changing that
[16:42:47] <Jymmm> you may have to
[16:42:51] <cncjerry> is 49065 really bad?
[16:42:56] <jdh> no
[16:43:17] <jdh> but a $79 atom cpu/board will get much less

[16:43:37] <cncjerry> like I said, this ran perfectly for years, I upgraded because I saw a problem with CV on certain cuts

[16:44:00] <cncjerry> It only goes that high when I was moving a lot around
[16:44:19] <Jymmm> it should never go that high =)
[16:44:24] <jdh> worst case is what will happen, at the worst possible time.
[16:44:27] <cncjerry> it is 4863 if I let it sit
[16:44:53] <jdh> read the above url
[16:45:17] <jdh> do you have new video drivers or other new stuff also?
[16:46:12] <cncjerry> no, the only thing I added was a new USB keyboard. other than that, it is the same system. oh, and I gave it its own partition instead of the windows drive
[16:46:35] <Jymmm> cncjerry: was a PS2 keyboard before?
[16:46:48] <cncjerry> are there settings in the system for pulse rate or something? I have this tuned down, it will do 300ipm but I only run it at 60ipm
[16:46:58] <cncjerry> yep
[16:47:01] <cncjerry> was ps2
[16:47:08] <cncjerry> duh

[16:47:13] <cncjerry> didn't think of that
[16:47:22] <cncjerry> wish I could.
[16:47:28] <cncjerry> had a little accident
[16:47:34] <Jymmm> It's not a fix, but a crutch
[16:48:11] <cncjerry> this is a 3mhz p7? can't remember, but it was a high end chip when I built it 8yrs ago.
[16:48:39] <Jymmm> no such thing as a P7 =)
[16:48:55] <cncjerry> ran perfectly except I saw a facet problem on outside corners under consant velocity so I thought I would try the new version
[16:49:25] <cncjerry> ok, socket 7? come on, cut me a break, it has been years. and by the way, I worked for IBM on the PC prior to it coming out in 1980\
[16:49:43] <jdh> wow, and still going?

[16:53:30] <cncjerry> I thought there was a cv change after

[18:24:14] <A2Sheds> andypugh, thanks for the low pressure steam turbine links, ends up they only want to cool the steam down to 80 deg C and release it into the sewer
[18:24:25] <A2Sheds> sorry 80 deg F
[18:24:49] <andypugh> That's still a fair bit of energy to recover
[18:25:23] <andypugh> Are you saying that they don't want that energy back?
[18:25:38] <A2Sheds> cooling tower with 2000A 480VAC is on the top of their list
[18:26:14] <andypugh> Can't you show them the maths?
[18:26:16] <A2Sheds> they don't want to exchange the heat to preheat the water supply into the autoclaves
[18:26:45] <andypugh> Not preheating might make sense, but they could generate significant amounts of electricity.
[18:26:54] <A2Sheds> they mostly just want to cool the steam and dump it into the sewer
[18:27:22] <andypugh> Yes, but, the turbine will cool the steam, and possibly power a cooling statge.
[18:27:45] <A2Sheds> yeah, not too interested, but they will think about it
[18:28:08] <A2Sheds> not sure if it's the NIH syndrome or ??
[18:28:49] <andypugh> And they wonder why the US burns more fuel per capita than anywhere else.
[18:29:28] <A2Sheds> 50M BTU/hr x 4 = 50MW and with losses in the turbine and generator you still end up with ~15MW
[18:29:41] <A2Sheds> gas fired autoclaves
[18:29:47] <andypugh> What is that in $ per day?
[18:30:00] <A2Sheds> 6 cents per KWH
[18:30:47] <andypugh> $20,000 per day.
[18:31:23] <A2Sheds> 15MW x 12 hrs = 180,000 KWH = $10,800/day
[18:31:46] <andypugh> They could consider themselves as a gas-fired power station and get cement board as a byproduct
[18:31:56] <A2Sheds> heh, yeah

[18:32:04] <andypugh> I was running 24 hours a day.
[18:32:12] <jdh> someone would probably pay them to dispose of their waste heat for them.
[18:32:40] <andypugh> If they had flue-gas desulphurisation they could make gypsum board as a byproduct too.
[18:32:55] <A2Sheds> yeah, they run for 2 hrs, when they reach 130 PSI they stop and then run down to 0 over 2 hrs
[18:33:05] <djdelorie> they could heat the surrounding neighborhood's houses too

[19:20:06] <tjb1> 1/4" square tubing in place of the extrusion?

[20:38:15] <andypugh> http://uk.rs-online.com/web/p/optocoupler/7344962
[20:38:44] <andypugh> The problem with a conventional optocoupler is that it doesn't suck the charge back out of the capacitor, so youneed a bleed resistor.
[20:40:02] <andypugh> That device needs PWM and logoc gnd to 2 pins on one side, and +10V and VFD gnd on the others, and the middle one is then a virtual pot.
[20:40:07] <MrSunshine> andypugh, humm ? what capacitor? :)

[20:55:26] <tjb1> Just took a look, every extrusion has a "crease" at the same area
[20:55:27] <andypugh> MrSunshine: So, presumably a capacitor and resistor then?
[20:55:37] <tjb1> Just 2 of them appear to actually have a noticeable bend at this crease
[20:55:56] <MrSunshine> two filters, an opamp for low impedance output and another capacitor for some extra voltage smoothing (optional dont know if i will need it) :P
[20:56:28] <MrSunshine> just a acap and resistor i only got 6V out of it
[20:56:30] <Connor> tjb1: Send'm back and order from 80/20
[20:56:38] <MrSunshine> when hooked up to the vfd
[20:57:03] <tjb1> The thing is Connor, this place quoted me much lower than 80/20 and the shipping was also free for me
[20:57:16] <Connor> tjb1: You get what you pay for ?
[20:57:51] <taiden> ygwypf
[20:57:55] <tjb1> Connor: I dont exactly think they are the harbor freight of extrusions
[20:58:29] <Connor> Didn't say that. But. I know 80/20 would not except that sort of imperfection in their product either.
[20:58:52] <Connor> I mean, they sell linear pads and stuff to use with their product.. it HAS to be straight for that kind of thing.
[20:58:53] <tjb1> I will be able to get 2 working pieces out of it
[20:59:11] <andypugh> MrSunshine: Ah, well, that chip + 1 resistor + 1 capacitor gives me full-swing and linear.
[20:59:13] <Connor> Yea, you'll have to cut it right at the bend.
[20:59:15] <tjb1> I will have to watch which side I use if I want to do any routing but the THC will take care of that
[20:59:32] <Connor> THC ?
[20:59:35] <andypugh> I guess your OP-amp solves the push-pull problem in your circuit.
[20:59:39] <tjb1> torch height control
[20:59:47] <tjb1> It can compensate for it but a router wont
[20:59:59] <tjb1> but then again I could face the spoilboard on the router to take care of that
[21:00:13] <Connor> You should do that anyway.

[21:00:39] <MrSunshine> andypugh, dont know realy what it solves more then that i can supply current and it will self adjust if voltage drops :P
[21:00:41] <tjb1> Guess I will just try to place the extrusion so it has the least effect and then eliminate it those ways
[21:01:29] <Connor> Yea, instead of placing it so the bend affects the Z..rotate it 90 degrees.
[21:01:42] <MrSunshine> andypugh, yeah that device looked neat =)
[21:01:56] <Connor> What size did you get ?
[21:02:21] <tjb1> Its 3"x3"
[21:02:36] <Connor> You have a 3"x"3 with a bend in it?
[21:02:39] <Connor> Wow.

[21:03:38] <tjb1> Its hard to get a picture of it
[21:03:52] <tjb1> But if you look straight down the extrusion, you can actually see the light change where the bend is
[21:04:15] <tjb1> This is the first one - http://sphotos.xx.fbcdn.net/hphotos-snc7/488111_4007149533112_1465635904_n.jpg
[21:04:20] <Connor> how long is that ?
[21:04:30] <tjb1> The whole extrusion?
[21:04:33] <Connor> yea
[21:04:39] <tjb1> 10ft
[21:04:45] <tjb1> The bend occurs at 26.5" on both
[21:05:05] <Connor> Clamping it maybe for cutting it while it's still hot ?
[21:05:27] <tjb1> Either that or this is happening when the extrusion hits the first support roller maybe?
[21:05:36] <andypugh> I wonder if you could push the kink out with a hydraulic jack?

[21:07:13] <Connor> I could see a slight crown over the whole length.. but, that's just not right.
[21:07:25] <tjb1> Yeah it occurs at one area

[21:08:13] <Connor> That doesn't sound like it happened at extrusion.. sounds like it happened after the fact.. shipping, storage, or something else.
[21:08:31] <tjb1> But a bend at the exact same point on 2 pieces?
[21:08:37] <tjb1> shipped two different companies
[21:08:43] <Connor> Then not shipping.
[21:08:52] <Connor> but, storage, or handling at the factory.
[21:08:55] <andypugh> http://www.ebay.co.uk/itm/110911991199 I have a bidder! I wonder if he has failed to grasp just what a big set it is? His other purchases don't hint at him having a huge machine tool.
[21:09:19] <tjb1> Just because you have a bidder doesnt mean they are going to pay ;)
[21:09:47] <Connor> Could be they have the parts laying flat on the ground with more stacked and had something under 1 side..
[21:09:48] <andypugh> I have been tripping over it for so long tghat the £75 it cost me is long forgotten
[21:09:59] <tjb1> The other pieces actually have a "crease" at the same area
[21:10:06] <tjb1> But they arent bent enough to affect anything
[21:10:15] <tjb1> It has to be something during extrusion
[21:10:39] <Connor> maybe 10' is just too damn long for them..
[21:10:51] <tjb1> I guess they are 20' long pieces?

[22:17:41] <andypugh> gmagno: A bit late, but simply inverting the "dir" pin might do what you want.
[22:18:11] <andypugh> But, if jog-up moves the axis down, I think the problem is that you have defined the axis end-points the wrong way round.

[22:46:08] <Tom_itx> r00t4rd3d i'm talking about rigid standoffs
[22:46:21] <Loetmichel> Tom_itx: the axles of steppers this size are hardened steel 1/4"
[22:46:24] <r00t4rd3d> people use plastic
[22:46:29] <andypugh> The mount is fine. The coupling might be fine too. But, you need to tighten the coupling _then_ the motor mounts.
[22:46:51] <Loetmichel> i would call it impossible to break them with a bit flex in the angle mount
[22:48:04] <andypugh> Flex in the mount isn't a bad thing. The problem is that the axis of the motor and the axis of the leadscrew were not 100% aligned.
[22:48:06] <r00t4rd3d> the guys at Sparkfun are pretty amazed i broke it too
[22:48:20] <Loetmichel> btw, r00t4rd3d: this coupler is NO angle compensating type, or is it?
[22:48:27] <Loetmichel> just a double clamp?
[22:48:46] <r00t4rd3d> one end is threaded for 3/8 rod and the other 1/4 shaft
[22:48:59] <Loetmichel> that is a bit "not good", even if your motor mount is relatively ductile ;-)
[22:49:23] <r00t4rd3d> im going to get another flex mount like i have on my y axis
[22:49:36] <Loetmichel> for the next stepper: get some flex couplers
[22:49:40] <Loetmichel> ;-)
[22:49:45] <andypugh> Ah, that's a poor design then. The threaded rod will never truly align in the coupling.
[22:49:47] <Loetmichel> flex MOUNT?

[22:52:25] <r00t4rd3d> all 3 of my axis are totally different in motion
[22:53:00] <Loetmichel> andypugh: me too
[22:53:14] <Loetmichel> i have experimeted with cheap bicycle chain also
[22:53:24] <Loetmichel> but have scrapped that as too loud ;-)

[22:54:46] <r00t4rd3d> i might put a belt on this one too. I have an extra gear for 3/8 rod
[22:54:52] <Tom_itx> i must be missing a step. i shared my nc_files dir and installed the windows network thingy but i can't connect to the directory
[22:54:57] <Tom_itx> ?
[22:55:06] <Loetmichel> works, no measurable backlash, but hell of a nouse at high rpm ;-)
[22:55:13] <Loetmichel> noise
[22:55:19] <jdh> can you see the computer from the winbox?
[22:55:22] <Tom_itx> it asks for a password but won't allow mine
[22:55:34] <jdh> you have to use smbpasswd
[22:55:58] <Loetmichel> Tom_itx: generate a suser in the windows box named like the linux user
[22:56:16] <Loetmichel> or set the windows dirs to "r/w for all"
[22:56:46] <jdh> I have a hard drive hooked up to my router. I save win* stuff to it and mount it under my nc_files dir

[23:22:58] <Connor> I dove with the Sherwood..
[23:23:09] <Connor> The Tusa looks way crapper to me.
[23:23:19] <jdh> I'd agree :)
[23:23:42] <jdh> I'll look for a NPT fitting for it when I go back out.
[23:23:45] <Connor> So, use the Tusa for the regulator for PDB then and leave my Sheerwood alone.

[23:33:06] <Connor> I'll have to remove the stupid console rubber and investigate it.
[23:33:22] <Connor> all 2nd stages looked good.
[23:33:33] <Connor> I wouldn't dive with them right now though.
[23:34:30] <Tom_itx> well crap. i need a couple more inputs
[23:37:21] <jdh> there are two tiny o-rings on the HP swivel. lube and twist them.
[23:38:23] <Connor> for the gauge?
[23:38:40] <Connor> I don't think it swivels..
[23:38:59] <jdh> yeah. It does.
[23:39:12] <Connor> I've had these Since 1995.. and They had to be 10 years old when i got them. :)

[23:43:42] <jdh> or Totally Useless Scuba Apparatus
[23:44:00] <Connor> and the LP's are on a swivel connector..
[23:44:12] <jdh> hose routing. use one or the other
[23:44:25] <Connor> Ah. Left or right handed..
[23:44:29] <Connor> my Sherwood isn't like that.
[23:45:08] <jdh> thats not a bad one then. its a scubapro mk5 clone
[23:45:54] <Connor> Well.. it's in worst shape than the sherwood and I've never used it.. so.. I think it's the one that'll be used for the power drawbar.
[23:46:44] <jdh> I think I have 14
[23:46:58] <Connor> have 14 what?
[23:47:02] <Connor> Regulators?

[23:47:31] <Connor> I'll need to find some plugs for 2 of the LP hoses...
[23:48:18] <jdh> i have lots
[23:48:43] <Connor> okay, got the boot off of the gauge.. no hotwater needed..
[23:50:11] <Connor> not seeing how you can take the gauge off.. it swivels between the joint that's leaking.. and I don't see any other joints??
[23:50:54] <jdh> flat on the gauge and the next one down
[23:51:18] <Connor> ok.
[23:51:49] <Connor> then I should be able to pull the hose through the boot.
