[07:37:55] <RyanS> Was at a machinery dealer today and was having a play with a 400 by 1000 lathe, huge in real life. don't really get an impression of size from videos

[07:49:32] <mrsun_> 400x1000 what ?
[07:49:43] <mrsun_> you know that this channel isnt all american or all outside american? :P
[07:49:45] -!- jsskangas has quit []
[07:50:29] <mrsun_> biggest freakin lathe ive seen is a vertial lathe that took pieces of upwards to like 40 tonnes :p
[07:50:41] <RyanS> That would be pretty big if it were inches :p mm
[07:51:22] <mrsun_> could be feet :P
[07:51:47] <RyanS> , I'm saying that although comparativelynot all that big.. They feel massive
[07:52:28] <RyanS> Just watching a video of a similar thing blasting off 6mm in steel
[07:52:38] <mrsun_> but what is the 1000 then ? mm and is it lenght of the bed or what? :)
[07:54:34] <RyanS> Aren't they usually specified as swing x between centres ? :P
[07:54:54] <RyanS> mm
[08:00:17] <mrsun_> ahh =)
[08:00:23] <mrsun_> well i dont know realy =)
[08:00:39] <mrsun_> swing, is that from center to bed or total swing? :P
[08:00:44] * mrsun_ feels stupid =)
[08:04:11] -!- sandorkr_ has quit [Remote host closed the connection]
[08:09:06] <archivist> americans quote the diameter they can swing, europeans the centre height
[08:09:53] <mrsun_> oh! =)
[08:09:57] <RyanS> Because Americans want bigger :)
[08:09:59] <archivist> some quote the total bed length and others the between centres distance
[08:10:29] <mrsun_> so before mentioning what i have a i need to write "im a european with a 20x100 lathe!" =)
[08:10:41] <mrsun_> 200x1000
[08:10:43] <mrsun_> i mean :P
[08:11:09] <RyanS> Suffice to say some lathes are fucking big :)
[08:11:09] <mrsun_> but im realy a trojan horse with a 400x1000 ! :P
[08:12:43] <archivist> americans remove the saddle distance, eu ignore that

[08:12:51] <_DJ_> moin
[08:13:00] <RyanS> so I got the three phase drill press , I was talking about... so will get delivered next week while I source a VFD
[08:13:52] <archivist> what does the label on the motor say
[08:15:43] <RyanS> didn't really see it but, 1.5kw, 3p, 415v.. Not sure about rpm
[08:17:15] <archivist> the plate will also say 220v with a delta sign if easily rewireable
[08:18:05] <RyanS> ah , that would be inside the junction box. I guess
[08:18:30] -!- The_Ball [The_Ball!~ballen@c114-77-185-26.hillc3.qld.optusnet.com.au] has joined #linuxcnc
[08:19:09] <RyanS> if not , you have to open the motor and do some rearranging so I'm told
[08:21:27] <RyanS> Just not sure whether to wait for sourcing VFD until I've actually had a look inside
[08:23:51] <RyanS> Is Delta Electronics any good? A number of suppliers in Melbourne have them
[08:25:45] <archivist> "do some rearranging" has included some unwrapping of the coils to find the joints for me
[08:26:21] <archivist> or you pay extra and get a 415 out inverter (costs a lot more)
[08:26:49] <mrsun_> atleast here a motor has to be 415-690 volts to be delta connected, else its Y connection that is required
[08:27:01] <mrsun_> 230V/coil 415V/phase-phase
[08:27:13] <mrsun_> delta will put 415V over each coil
[08:27:53] <mrsun_> wait .. is it 480 .. hmm oh well =)
[08:28:10] <RyanS> My friend is an electrical engineer so he can probably help out if I'm stuck
[08:28:30] <mrsun_> but in america i guess its 220V Delta as they have 110V/phase right?
[08:28:59] <mrsun_> so 220-415 motor is supposed to go delta while a 110V motor has to be Y :P
[08:29:01] <archivist> americans are strange with electricity and wiring
[08:29:06] <RyanS> I am in Australia, so we run 230 V in single phase
[08:29:21] <RyanS> 415v 3p
[08:29:40] <Jymmm> archivist: Wiring?
[08:30:17] <mrsun_> like sweden then =)
[08:30:34] <mrsun_> so if the motor is not specified as 415 - 690 or so V then do NOT delta connect it =)
[08:31:12] -!- patrickarlt has quit [Read error: Operation timed out]
[08:32:03] <RyanS> it needs to be star in that case?
[08:32:38] <archivist> 220 to an american is +-110 its a single phase line
[08:33:27] <Jymmm> archivist: Not if I run two extension cords to both sides of the panel =)
[08:33:36] <RyanS> archivist is this what you had to do to locate the joints http://forums.aeva.asn.au/forums/changing-an-induction-motor-voltage_topic1237.html
[08:35:55] <archivist> RyanS, that is a special case as he is changing the number of poles too
[08:37:04] <archivist> star to delta does not change the number of poles
[08:37:45] <RyanS> but what you have to do would not be too major for electrical engineer to rewire?
[08:38:10] <archivist> just have to find the star point, disconnect, and reconnect as delta
[08:38:45] <archivist> similar in that one is getting inside and nearly as much
[08:38:46] <RyanS> What about unwrapping the coils if necessary?
[08:38:59] <archivist> yes that too
[08:39:15] <archivist> there are some safety implications
[08:39:44] <RyanS> ok, well, I'm not too concerned if I get my mate to help out
[08:40:31] -!- vladimirek [vladimirek!~vladimire@] has joined #linuxcnc
[08:41:01] <archivist> a good sparky will have an insulation tester and be able to verify the work is ok
[08:41:53] <Jymmm> archivist: Insulation tester? (continuity?)
[08:42:24] <RyanS> I think this drive *might* be able to go from 230v to 415v https://oceancontrols.com.au/DEM-005.html
[08:42:45] <archivist> Jymmm, no to test the wire is not leaking to the case
[08:43:16] <RyanS> "Maximum Output Voltage: 3F Proportional to Input V."
[08:43:46] <archivist> note at the top it states 240 out
[08:44:14] <Jymmm> archivist: Ah
[08:45:05] <RyanS> ok I see it now
[08:50:04] <RyanS> 230v to 415v must be pretty uncommon indeed, because I haven't come across any yet whilst browsing
[08:53:42] <archivist> I think I saw one at twice the price
[08:54:30] -!- geografa has quit [Quit: Computer has gone to sleep.]
[08:56:00] <RyanS> hmm a motor servicing company gave me an estimate of about $500 to do the conversion for me.. It's tempting to go that route considering that's only about 200 more than the drive itself
[08:57:42] <archivist> this is a label for an easy to change motor http://i.ebayimg.com/t/Variable-Speed-VFD-Inverter-with-Crompton-Motor-for-Myford-Boxford-Lathe-Milling-/00/s/MTYwMFg5NzY=/z/hKUAAOxyTjNSjN~a/$_12.JPG
[08:59:21] <RyanS> ok volts 'delta' 220/250v
[09:01:15] <RyanS> I don't know if 'new Chinese import' gives any clues. http://www.appliedmachinery.com.au/machinery/97451/machtech-drilling-machine-bd35
[09:01:42] <archivist> a motor like that has 6 connections and an internal connection diagram and 3 links
[09:02:35] <archivist> that page tells us nothing we have to look at the motor label
[09:02:48] <RyanS> The junction box will have six screw terminals?
[09:03:12] <archivist> if easily changeable yes
[09:03:33] <RyanS> If not, you'll just see three screw terminals?
[09:03:34] <archivist> 3 if you have to get at the windings
[09:03:51] <RyanS> hehe beat me to it
[09:04:18] <archivist> they could fit a 6 stud plate and be lazy so beware
[09:05:13] <MattyMatt> 415V is 240V when 3 phase, so that's probably what they mean
[09:06:29] -!- rob_h [rob_h!~rob_h@] has joined #linuxcnc
[09:06:36] <RyanS> hmm and I think some of them have dodgy labels or lack of
[09:07:54] <archivist> newer motors know they may be used on a vfd so come wired with 6 studs and a sensible label
[09:08:47] <RyanS> http://res3.graysonline.com/handlers/imagehandler.ashx?t=sh&id=1847922&s=gl&index=0&ts=634830121023630000 I don't think this example is sensible (not my drill)
[09:09:35] <MattyMatt> that's common british label style for 3 phase
[09:11:29] <MattyMatt> you see 415V everywhere in old factory equipment, it means 3 phases of 240V
[09:12:26] <MattyMatt> vfd specs I've seen state the output per phase
[09:16:05] <MattyMatt> ah, the discussion is the coil wiring, not the voltage. sorry for butting in
[09:16:40] <RyanS> Conversely, would something like a ubiquitous 4x6" bandsaw be able to be rewired as three-phase?
[09:17:59] <archivist> how can we know without looking at the motor
[09:18:44] <archivist> motors are easy enough to replace anyway
[09:19:24] <RyanS> Well from . Going by the sort of motor typically supplied with that type of machine
[09:20:00] <archivist> silly question, was the machine a single or 3 phase machine
[09:20:02] <MattyMatt> they are either 1 phase or 3 phase
[09:20:19] <RyanS> They probably will come from the same factory
[09:20:24] <RyanS> 1p
[09:20:48] <MattyMatt> 1 phase motor is 1 phase forever
[09:22:51] <MattyMatt> they are stuck at their design speed, unless you want to reduce voltage and power
[09:23:15] <RyanS> ok
[09:23:18] <archivist> so one looks at the spec, there is no typical

[09:28:37] <RyanS> Three phase motors have higher torque by design. Is that correct?
[09:30:05] <MattyMatt> they can use 3x as much power, and their torque doesn't pulse at 50Hz
[09:30:07] -!- psha has quit [Quit: Lost terminal]
[09:30:25] <archivist> er what!
[09:30:51] <MattyMatt> when each phase crosses 0V, the other 2 are still supplying power

[09:31:34] <RyanS> Anyway I have Cox (1996) electric motors in the home workshop. It looks pretty helpful, so will have a read over the weekend
[09:31:34] <Valen> mesa have a *store*???? WTH
[09:32:09] <archivist> Valen, been an open seqwet for a month or three
[09:32:18] <Valen> Dr Google knows about it now
[09:32:28] <MattyMatt> what I mean is, typical 3 phase supplies can provide 3x the power to use, typically. that's negotiable with your electricity supplier of course
[09:32:50] <MattyMatt> thicker wires and fuses etc
[09:32:54] <archivist> MattyMatt, I think you maths dont add up
[09:33:10] <MattyMatt> IANAEEng :)
[09:33:14] <archivist> you can put thick wires on single phase
[09:33:28] <MattyMatt> true that
[09:33:58] <archivist> the reasons are to do with how the motors work not the supply method
[09:34:02] * Valen is tossing up between a 60A single phase and 32A 3 phase connection for some computers I'm getting
[09:34:05] <MattyMatt> you need to pay big money to get more than 60A per phase in UK tho, afaik
[09:34:08] <Valen> well that i have

[13:27:12] <terrym> Hi
[13:27:46] <jdh> Hello TerryM, how are you this fine $TimeOfDay
[13:28:13] <terrym> Good, mid morning here in Florida.
[13:29:08] <terrym> My mill has a rotary table, XYZA, is there a way to set a tool change position that does not move A?
[13:30:56] <jdh> I will be in Florida in ~11 hours!
[13:31:22] <terrym> I tried TOOL_CHANGE_AT_G30, then I tried TOOL_CHANGE_POSITION = 0.098 6.4 14.785, note no A given.
[13:31:48] <terrym> Still it move the rotary table to 0deg. every tool change.
[13:31:56] <jdh> I have no A, nor tool change position, so no experience.
[13:32:21] <terrym> Where in Florida are you going?
[13:32:40] <jdh> High Springs
[13:32:58] <jdh> with possible stops in Branford and Luraville
[13:33:13] <terrym> Ah, about a four hour drive from here as I recall.
[13:33:52] <terrym> Oh, ya, Branford is where my folks live, that is a 5 hour drive from me.
[13:34:54] <terrym> Do you do manual tool changes?
[13:35:00] <jdh> I do
[13:35:14] <jdh> but, I split my code up by tool
[13:35:29] <jthornton> terrym, you might have to just move to the tool change position in G code
[13:36:19] <terrym> Yes, I considered that ... would rather not.
[13:36:23] <Tom_itx> http://www.linuxcnc.org/experimental/gutsy/emc2_2.2.0pre_i386.changes
[13:36:29] <Tom_itx> that might address it also
[13:36:50] <jdh> sounds likely
[13:37:01] <Tom_itx> Tool change position can have an ABC component. Previously rotary axes
[13:37:01] <Tom_itx> always moved to 0 for a tool change.
[13:37:07] <Tom_itx> what what led me to that
[13:38:00] <jdh> also 6 years old
[13:38:35] <terrym> Thanks, I'll take a minute now and read that.
[13:38:57] <jthornton> Tom_itx, is this what your looking at G28/G30 now move only the specified axes to the home/reference point
[13:39:06] <Tom_itx> ok
[13:39:43] <jthornton> or this Tool change position can have an ABC component. Previously rotary axes
[13:39:43] <jthornton> always moved to 0 for a tool change.
[13:40:33] <Tom_itx> if you use G28 make sure Z is on a separate line or you may regret it
[13:40:57] <jthornton> All axes defined in the ini file will be moved when a G28 is issued
[13:41:28] <jthornton> All axes defined in the ini file will be moved when a G30 is issued.
[13:41:28] <Tom_itx> i use G28 X0 Y0 and only those move
[13:41:36] <terrym> Hum, it indicates that a position for the table can be specified, but I just want to leave it where ever it is.
[13:41:49] <Tom_itx> read the current position then
[13:44:43] <Tom_itx> N141 G49 G28 Z0
[13:44:43] <Tom_itx> N142 G28 Y0
[13:44:59] <Tom_itx> moves Z out of the way then brings the table out to change parts
[13:45:03] <Tom_itx> affects no other axis
[13:46:43] -!- FreezingCold has quit [Ping timeout: 272 seconds]
[13:46:54] <jthornton> seems the manual description is incorrect
[13:47:14] <terrym> OK, I guess that could be worked into M6? I have not yet tried defining my own M codes.
[13:47:59] <Tom_itx> my post just spits that out on a change or end of file
[13:48:21] <jthornton> you have to be running master to change G codes

[13:54:47] * jthornton fixed the docs, thanks Tom_itx
[13:57:17] * Loetmichel should reprogram the heating system over here at the company... it is freezing in the company.

[14:25:00] <GuShH> Hi, I've been told a few people around here do their own aluminum anodizing, any pointers on getting started and could someone explain me if sulfuric acid is a must or if other acids can be used (why not HCL?)

[14:28:04] <GuShH> But it seems I wasn't the cause for all the nonsense in the channel
[14:28:05] <archivist> a few missed you
[14:29:42] <GuShH> I've used HCL to dissolve aluminum from brass fittings (broken males that couldn't be removed by mechanical means) I noticed it etches the surface very quickly leaving a rough finish, similar to blasting it with oxide but not quite... is desmut required afterward?

[14:31:06] <archivist> I worked at an anodizing co 40 years ago, just remember breathing in the atmosphere there
[14:31:24] <GuShH> I would imagine it's rather different on a big scale!
[14:31:47] <archivist> there were caustic and sulphuric vats
[14:31:54] <GuShH> What I would not even dare try is plating of any kind other than zinc
[14:32:10] <archivist> I never caught a cold while working there
[14:32:12] <GuShH> nickel, chrome... no thanks.
[14:32:30] <GuShH> it must kill everything in it's path!
[14:32:50] <GuShH> perhaps the acid question belongs to the chemistry channel
[14:33:16] * GuShH just found out "clear coating" exists in powder form as well
[14:33:18] <archivist> jt in here is making a small anodizing line
[14:33:32] <GuShH> this would be mostly for a personal experiment (always wanted to do it)
[14:33:54] <GuShH> I don't think it would be easy to get repeatable results for a commercial application
[14:35:11] <GuShH> not without time, ph and temperature control at least, which requires patience, which I don't have anymore.
[14:35:23] <archivist> just need a chemist on site for commercial to keep the mix right
[14:36:01] <GuShH> I have a guy that does this for a living, I just don't want to bug him over silly questions plus there's no way they would tell me every single secret.
[14:36:26] <GuShH> he did tell me the 2000 series is basically impossible to anodize properly specially if you want a glossy finish
[14:36:55] <GuShH> which makes sense given they're trash alloys
[14:40:41] <CaptHindsight> GuShH: http://www.caswellplating.com/kits/index.html
[14:40:48] <archivist> we used to rub lanolin into the surface to fill the pores
[14:41:01] <GuShH> CaptHindsight: the idea is not to buy a kit, but thanks - also I've been staring at forums for a while, just haven't got to try anything yet
[14:41:21] <CaptHindsight> http://gnipsel.com/anodizing/anodizing.html
[14:41:27] <GuShH> oh I just saw lanolin (used for cosmetics right?) on a chem supply site I was browsing seconds ago
[14:41:59] <GuShH> CaptHindsight: is that your site? Tom_itx already pointed me to that URL, thanks though.
[14:42:21] <GuShH> also your table is crooked.
[14:42:59] <GuShH> (http://gnipsel.com/shop/hardinge/hardinge-13.xhtml)
[14:43:01] <CaptHindsight> GuShH: not my site
[14:43:08] <GuShH> aww
[14:43:17] <archivist> that is jt
[14:43:40] <GuShH> I just found it hilarious that he would have all of these machines but he couldn't be arsed to build a proper table
[14:44:13] <GuShH> Almost equivalent to driving a Ferrari on flipflops and a hawaiian shirt, not quite as bad though.
[14:44:25] <archivist> when he makes something it will be over engineered :)
[14:44:30] <CaptHindsight> GuShH: there are other acids that may be used to anodize aluminum but it's beyond what you're up to
[14:44:34] <GuShH> archivist: I like him already
[14:44:46] <GuShH> CaptHindsight: elaborate?
[14:44:52] <CaptHindsight> they are used to control thickness of the oxide layer as well as pore diameter
[14:45:22] <GuShH> I thought that was mostly up to the anodizing time, interesting
[14:45:26] <archivist> or time in the vat and current
[14:45:42] <GuShH> So given the right amps per square feet most of the structure is controlled by the electrolyte?
[14:46:00] <GuShH> seems counterintuitive
[14:46:09] * GuShH idly scratches archivist's head
[14:46:25] <archivist> I am not a chemist no idea and my experience is 40 years forgotten
[14:46:57] <GuShH> CaptHindsight: is pore diameter highly relevant to the type of dye or are there other reasons for wanting a specific size?
[14:47:04] <archivist> factory still looks the same https://maps.google.co.uk/maps?q=lichfield&hl=en&ll=52.760736,-1.795503&spn=0.001091,0.002409&sll=52.8382,-2.327815&sspn=8.925147,19.731445&t=h&hnear=Lichfield,+Staffordshire,+United+Kingdom&z=19
[14:47:15] <CaptHindsight> most anodizers don't really know what's happening down at the nanoscale, they just follow recipes
[14:47:24] <GuShH> I would imagine this goes very deep into chemistry, but you're right I'm not very interested in those details at the moment (I am interested in a few, just not all of them)
[14:47:42] <GuShH> Don't worry the same happens with anything related to chemistry, it's just not my thing
[14:47:58] <GuShH> I can appreciate it but up to a point.
[14:48:12] <archivist> for pretty you just need a thin layer, we were making window parts so needed a long life
[14:48:24] <GuShH> I actually want dull black, thick layer.
[14:48:28] <GuShH> for durability
[14:48:37] <GuShH> well not dull, matte.
[14:48:46] -!- Simooon has quit [Quit: Leaving]
[14:48:47] <CaptHindsight> what will it be exposed to?
[14:48:49] <GuShH> however I don't want to blast with aluminum oxide (don't have the means)
[14:49:03] <GuShH> general abuse at our lovely atmosphere.
[14:49:12] <GuShH> and some moisture.
[14:49:13] <archivist> you are creating an oxide in the process
[14:49:54] <CaptHindsight> by durability do you mean fade resistance? you want it to stay black?
[14:50:19] <GuShH> right, the idea is to make the part more durable. I just mentioned aluminum oxide as a blasting media since that's generally the best way to blast aluminum, anything else might embed particles (say sand = silica) which will spoil the anodizing
[14:50:35] <GuShH> CaptHindsight: scratch resistance, does it actually leak and fade with time?
[14:50:43] <GuShH> or is that entirely up to the sealing process
[14:50:53] <archivist> I dont see why you would blast it after
[14:50:58] <CaptHindsight> color fade has to do with UV breaking down the dye
[14:51:02] <GuShH> for the matte / rough finish
[14:51:12] <GuShH> which is why I asked about HCL etching first, instead of blasting it
[14:51:15] <archivist> do that first
[14:51:20] <CaptHindsight> blasting will remove oxide
[14:51:39] <GuShH> I can't blast though, also it's a messy process
[14:51:49] <GuShH> without a cabinet I'm not willing to try it.
[14:51:53] <archivist> you finish is only going to be 5-30 microns thick
[14:51:57] <CaptHindsight> if you anodize over a rough surface it will stay rough/matte
[14:52:07] <GuShH> yes, you get what you start with
[14:52:14] <GuShH> which is fine
[14:52:29] <archivist> well is will be more matte than it was before
[14:52:32] <CaptHindsight> unless you brightcoat (chemically polish)
[14:52:53] <GuShH> don't plant ideas in my head... I haven't tried to anodize and now you want me to brightcoat!
[14:53:54] <GuShH> another reason for an hcl dip (prior to degreasing) was to see if I could get rid of machining marks
[14:54:16] <archivist> drgrease before strip :)
[14:54:19] <GuShH> but chances are it will etch away rather uniformly decreasing the diameter
[14:54:31] <GuShH> err I meant to say degreasing first then etching it
[14:54:43] <GuShH> otherwise the oils won't let the acid react with the surface
[14:55:43] <GuShH> CaptHindsight: while there are commercial dyes available, will the dyes used for clothing work just fine? specially the black
[14:55:57] <GuShH> or are the pigments too big
[14:56:31] <GuShH> I can picture it leaching off to white during sealing...
[14:56:51] <GuShH> Also is steam sealing worth a try or will streaks likely occur?
[14:57:07] <CaptHindsight> UV exposure breaks down the dye molecules, water won't effect the anodic layer, it's acids and especially alkalines that break down the oxide
[14:57:38] -!- psha[work] has quit [Quit: Lost terminal]
[14:57:40] <GuShH> the parts won't be exposed to UV for long periods so I'm not too worried
[14:57:44] <CaptHindsight> you can ball mill pigments that will fit in the pores
[14:57:51] <GuShH> and we're talking hobby grade anodizing anyway!
[14:59:06] <CaptHindsight> textile dyes can work, they are similar to what is used in type-II color anodize
[14:59:57] <GuShH> I'm just thinking "cheap, readily available" and that's one of them
[15:00:06] <CaptHindsight> and yes they do wash out during sealing, that is why the ph and temp of the dye bath are a bit critical and the sealing process
[15:00:09] <GuShH> I can even pick up those pigments at the grocery store
[15:00:53] <CaptHindsight> if the dye is water based and you also seal in water the dye will want to migrate out of the pores during sealing
[15:01:04] <GuShH> why isn't the sealing process flooded with dye then?
[15:01:19] <GuShH> do most dyes decompose with the temperature?
[15:01:41] <CaptHindsight> some dyes more than others
[15:02:08] * GuShH pouts
[15:02:27] <GuShH> This is one of those "it's an artform" things isn't it.
[15:03:12] <CaptHindsight> solvent dyes and pigments work much better, but it's not traditional

[15:05:23] <GuShH> JT_Shop: Amazing machines and love to know you put them to good use
[15:05:39] <JT_Shop> run them almost every day
[15:05:47] * JT_Shop goes to make some parts now
[15:05:57] <GuShH> I was told you make tooling of some sort?
[15:06:34] <GuShH> How much does the Hardinge weigh anyway? over 2 tons surely?
[15:07:10] <CaptHindsight> GuShH: http://electrochem.cwru.edu/encycl/art-a02-anodizing.htm probably more than you want to know
[15:07:49] <GuShH> Actually if I can understand the theory behind it I'll be able to get some usable results out of it

[15:08:56] * JT_Shop designs and builds automation equipment or digs graves for animals whatever people need
[15:09:10] <JT_Shop> the Hardinge is about 2-3 tons yes
[15:09:19] <Loetmichel> CaptHindsight: its easy enough to do at home
[15:09:52] <Loetmichel> if you have enough room and a floow which isnt shys of the occasional spill of NaOH or Sulfuric acid

[15:16:49] <GuShH> I bet CaptHindsight has done "some" anodizing

[15:26:48] <CaptHindsight> http://www.bluebuddhaboutique.com/blog/2011/09/no-white-anodized-aluminum/ pretty good simple explanation of how anodize and coloring works except that they are wrong. There is a process to produce white anodize.

[15:39:33] <GuShH> JT_Shop: you can hook the OnChange message/event or check one by one into an array / list if you desire
[15:39:41] <GuShH> there are many ways to skin it
[15:40:00] <GuShH> ie using getElementById() and accessing the value element
[15:41:03] <GuShH> for radio there's also the checked element
[15:41:50] <GuShH> say your FC nozzle has an id "radio1" then getElementById('radio1').checked
[15:42:04] <GuShH> assuming you are using bare js here
[15:42:20] <GuShH> let me know if you need a hand with it
[15:43:34] <JT_Shop> GuShH, thanks I'll give that a whirl in a bit
[15:45:25] <GuShH> GCode.js includes the methods additems, setedittext, etc? or which library does?
[15:46:11] <GuShH> I just saw the code, using the addItems method, what ID is actually defined for the radio? if you have the code for the high level library you can see more or less how it's dealing with the array you are giving it
[15:46:14] <JT_Shop> GCode.js is the base configuration and Plasma.js changes some things
[15:47:02] <JT_Shop> I added the radio buttons with hmmm what is that QT something
[15:49:30] <GuShH> sure but those methods / functions (whatever you want to call them) have to be defined somewhere, since it's not standard JS
[15:50:57] <GuShH> seeing how the input is handled you can find out if there are methods exposed to obtain the information you're looking for or at least, a cleaner way to deal with the radios

[16:46:49] <GuShH> archivist: but the part being machined, what could it be?
[16:46:58] <WalterN> well yeah, the machine is kind of obvious
[16:47:00] <GuShH> my best answer: anything
[16:47:16] <GuShH> at first I thought "unfinished crankshaft" but no
[16:47:27] <GuShH> since no intermediary step I'm aware of would yield that kind of "thing"
[16:48:26] <archivist> well it is mounted on rotaries but the function of the part one needs experience of that part methinks

[16:52:13] <GuShH> are you inside the scope of "this"
[16:52:14] <jthornton> it's a drill string stabilizer or wiper

[16:58:20] <archivist> bit of a drill being more accurate
[16:59:05] <jthornton> part of a drill bit yes and a very long one sometimes... deepest I ever drilled was 5 miles

[18:02:49] <GuShH> archivist: I've had gears strip teeth but never a fallen window...
[18:02:58] <GuShH> how old is old heh
[18:03:16] <Jymmm> No rust, nothing looks loose but could be as this is the 2nd time in a week. I added grease to everything after the first time and all seemed MUCH better. 1988
[18:03:28] <Jymmm> civic
[18:03:34] <GuShH> what type of grease? should be silicone based
[18:03:37] <GuShH> oh yeah I've worked on civics
[18:03:51] <GuShH> about 7 bolts or so and the entire assembly comes right off (you have to slide the glass up and out first)
[18:03:53] <GuShH> very easy
[18:04:00] <Jymmm> lithium, it's what I had and better than none at all
[18:04:09] <GuShH> the stripped teeth were on a civic si 1.6
[18:04:17] <GuShH> yeah but clean the channels first
[18:04:18] <GuShH> then grease
[18:04:22] <GuShH> otherwise it gets worse.
[18:04:31] <GuShH> make sure it's really in the tracks
[18:04:49] <Jymmm> Is it possible that it jumped teeth previously (pre-grease) ?
[18:05:00] <GuShH> factory manual says to use white lithium in fact
[18:05:06] <Jymmm> it's in the tracks for sure
[18:05:19] <GuShH> it doesn't go all the way up or jumps?
[18:05:41] <GuShH> If it's doing a repeated "tuck-tuck-tuck" sound means you've got missing teeth
[18:05:48] <GuShH> usually at the upper region
[18:06:09] <Jymmm> when rolling up, it pops out of the front track (closest t the door hinge) then binds up
[18:06:20] <GuShH> oh roll, so it's manual
[18:06:27] <Jymmm> electric
[18:06:36] <GuShH> could be bent
[18:06:40] <GuShH> cheap stamped steel assemblies, I hate it. they have so many design errors on those cars...
[18:06:52] <GuShH> so when the arm bends this tends to happen
[18:06:59] <GuShH> but that usually occurs with manuals
[18:07:15] <GuShH> because people keep cranking and adding more and more force (due to binding on dirty channels) and that just bends the assembly
[18:07:35] <GuShH> it's geared down enough that it can strip teeth given enough time, so I would think it could also start to bend on it's own
[18:07:44] <GuShH> bah the pics are on another hdd
[18:11:46] <GuShH> found 'em ... Jymmm http://gushh.net/tmp/regulator1.jpg -- http://gushh.net/tmp/regulator2.jpg --- http://gushh.net/tmp/regulator3.jpg
[18:11:59] <Jymmm> Well, I had been using the AUTO DOWN previously and would go down 25% then stop Puch the button again, another 25% or so, etc. The button is just a glorified circuit-breaker, that's when I added grease to everything I could and it was smooth again. one press and went down 100%.
[18:12:01] -!- dway has quit [Quit: NOOOOOOooooooooo……]
[18:12:01] <GuShH> this one wasn't bent but it had a worse problem
[18:12:20] <GuShH> yeah the stops-before-it-reaches is caused mostly by dirt and gunk
[18:12:45] <Jymmm> All the original grease wa dried up decades ago =)
[18:12:53] <GuShH> in this case the gasket or whatever you call it was bent inwards and kept forcing the regulator mechanism until the teeth stripped out entirely (that's my assumption, it could've been someone tried to steal the car too)

[18:13:35] <GuShH> I might like Honda but I dislike so many of their decisions heh
[18:13:50] <Jymmm> Hopefully the rain will hold off long enough for me to take a closer look at the whole thing.
[18:14:16] <Jymmm> Is there ANY adjustments on the window or regulator? I don't see any in your pics at all
[18:14:18] <GuShH> I think you can buy the new regulator with or without the motor, I would certainly want to keep the original if it's in good condition
[18:14:23] <GuShH> not really
[18:14:40] <GuShH> there's some play when you install it, but it's indexed by the window once you slide it down

[18:15:48] -!- geografa has quit [Read error: Connection reset by peer]
[18:15:55] <GuShH> you have to take the regulator out and see what it looks like, it should be evident
[18:15:55] <Jymmm> what year is that in the pics?
[18:16:00] -!- zzolo has quit [Quit: zzolo]
[18:16:26] <GuShH> prior to 2000 I think, up to 2004 or so they used a very similar regulator... in fact I bet it still looks just about the same, most cars are (it's either based on steel wire or levers)
[18:16:48] <GuShH> you do have tensioners with wire, specially on sliding doors
[18:17:03] <Jymmm> Mine looks like your pic with the scissor arms
[18:17:30] <GuShH> just be careful with the spring
[18:17:41] <GuShH> lots of potential energy stored in that thing
[18:18:56] <GuShH> I don't remember if it works as a preloader of sorts or if it aids in storing energy for when it has to go back up again.
[18:19:19] <GuShH> at any rate you just replace the whole thing unless it's bent, then you can shape it back and reinforce it so it won't happen again
[18:19:29] <Jymmm> Eh, I'll pull it all out and see if anything is bent/broke and regrease it all
[18:20:48] <GuShH> oh ... there are some teflon or similar rollers in the channel
[18:20:55] <GuShH> those do get damaged and cause trouble as well
[18:21:10] <Jymmm> That's where I added grease
[18:21:16] <GuShH> since it flops about when they are "tired"
[18:21:28] <GuShH> only way to make sure is taking it all out
[18:22:02] <GuShH> tricky part is removing the door handle, gotta be careful with those old plastics (mine was already snapped by the bezel / plastic cover)
[18:22:11] <Jymmm> If there are no adjustments as you say, then I'll have to.
[18:23:07] <GuShH> it has enough play that you could move it half an inch or so to the side, but I don't think that's anything other than clearance.
[18:23:26] <GuShH> the shop manuals are available online, I always read them first
[18:23:37] <GuShH> of course they call for special honda tools you'll never buy heh
[18:23:53] <Jymmm> special tools? for what?

[20:47:16] <Tom_itx> the FAA is reviewing it
[20:47:54] <Tom_itx> he left skidmarks all the way down the runway

[20:49:29] <GuShH> but what if the pilot flying the pilot does the same? then you'd have to fly more pilots to fly the pilots that were flying the pilots to fly the plane?
[20:49:38] <Tom_itx> there's only like 3 or 4 of these planes around

[21:57:27] <terrym> I was looking at the docs for DISPLAY section and noticed GEOMETRY.

[23:02:48] <terrym> looking at it ...

[23:07:14] <terrym> not sure from the image on that web page, but the rotary axis looks centered on machine zero?
[23:07:48] <terrym> that is, the coordinate vectors are at the center of the ring...
[23:08:14] <terrym> oh never mind
[23:08:28] <terrym> ... that would be G54...

[23:10:27] <Meduza> andypugh, DaViruz: since the spindle driver already use the quadrature encoder, i would propably need to buffer and split the signals if i want them both to linuxCNC and the driver
[23:11:15] <andypugh> There is probably no need to buffer.
[23:11:46] <andypugh> What sort of spindle driver is it?
[23:12:08] <andypugh> It might well have an encoder pass-through.
[23:12:37] -!- kiw has quit [Ping timeout: 248 seconds]
[23:12:43] <andypugh> What do you intend to count encoder pulses with? Be aware of the pulse-rate limits of your chosen counter.

[23:14:46] <Meduza> I intend to use just a parport

[23:16:29] <terrym> I notice that example used G92, so I tried that, no change.
[23:17:02] <terrym> It still displays to rotary table as centered on machine zero.
[23:17:20] <andypugh> terrym: Have you actually moved the G54 origin?
[23:17:29] <terrym> yes
[23:17:59] <andypugh> Meduza: There are two sets of encoder iterminals, but they seem to both be inputs.
[23:18:14] <terrym> machine zero is at the lower left corner of the table, G54 is about in the middle, both in X and Y.

[23:19:02] <andypugh> Meduza: I guess you were planning to use the Z terminal output for LinuxCNC?

[23:19:46] <cradek> terrym: just to be clear, you're asking about making the preview different, not any of the actual motion?
[23:19:57] <terrym> The current work shows at the correct place, but when the table rotates it is shown as swinging around machine zero.
[23:20:28] <terrym> correct
[23:20:31] <Meduza> andypugh: i have a encoder with separate index pulse, and was wondering since the drive does not use that if that would be enough feedback for linuxcnc
[23:20:57] <andypugh> Meduza: Try it.

[23:21:58] <terrym> Yes, the actual cutting is correct, just the way it is displayed in the preview is not.
[23:22:23] <andypugh> It will definitel work. It might not work well, mainly depending on the power and inertia of your spindle. It seems likely you have closed-loop speed control of the spindle, so the single pulse might work well.
[23:23:41] <Meduza> Ok, i'll try it then :)
[23:23:53] <Meduza> the power is not that great, this is a very small lathe ;)

[23:31:20] <cradek> terrym: if your setup is fairly permanent, you could just set your homing numbers to move the origin. it makes no difference where the actual unoffset origin is.
[23:32:43] <terrym> The rotary table is just on for this job, and there are only 2 and a half parts still to do ...
[23:32:56] <andypugh> kengu: Plasma?
[23:33:18] <kengu> yes

[23:34:00] <terrym> I have 3 'profiles' for the mill: XYZ, XYZA now XYZC, and A only for use with my manual mill.
[23:35:07] <terrym> most of the time I just use XYZ, no A

[23:42:08] <Jymmm> When installing replacement windows in cars, do they usually use some kind of thread lock?
[23:43:53] -!- maximilian_h has quit [Ping timeout: 245 seconds]
[23:46:09] <andypugh> Where?
[23:47:23] <Jymmm> the glass has two plastic piece that are cemented to the glass. These pieces are what bolt on to the track that moves up/down.
[23:48:15] <Jymmm> I was asking about thread lock on these two bolts.
[23:49:21] <Jymmm> I just finished removing, cleaning, greasing, and re-installing the window regulator assembly.

[23:49:57] <Jymmm> Glass (even tempered) scares the crap out of me =)
[23:52:46] <RyanS> If I rattle off the brands of VFDs that are available to me locally.. which are lowish cost but still decent? Delta, Toshiba, ABB, Weg, Invertek, Allen-Bradley, Santerno, SEW eurodrive (very local branch),
[23:54:32] <RyanS> I didn't say teco despite being available :)
[23:57:09] <andypugh> Toshiba and ABB definitely. Allen Bradley I would expect. I think SEW are decent too.
[23:58:33] <RyanS> yeah, are they necessarily expensive? I saw abb for a pretty decent price, even from RS
[23:58:44] <RyanS> Toshiba seemed pretty pricey
