[01:57:43] <andypugh> jthornton_: I might have a metal-spinning project. https://picasaweb.google.com/lh/photo/pYomg8CstFoxtFfEtJZyxNMTjNZETYmyPJy0liipFm0?feat=directlink
[02:01:22] <andypugh> Thing is, this is a historical object, a ritual object even. I noticed it was in a mess when offered the underlying drinking vessel to quaff from at the 90th anniversary ball of the club. You take the gallon cup, bow to your left, bow to your right, he takes the lid, you drink. Bow left, bow right, he puts the lid back on, you pass the cup left. So, the lid sees quite some wear.
[02:04:47] <andypugh> The copper ring was added recently, and was not a great plan. It might have been OK soldered on, but it was just rolled in to what appears to be the original rim, stretched.

[02:19:30] <Valen> dont think pewter tigs andypugh
[02:19:41] <Valen> braising is the common answer i believe
[02:20:28] <andypugh> Soldering is conventional. But I woulf hate to melt the whole thing.
[02:20:55] <Valen> well before you start whats the end goal?
[02:21:29] <andypugh> To make it not look broken, and survive 100 more years.
[02:21:45] <Valen> so what bit comes apart?
[02:22:00] <andypugh> ?
[02:22:05] <Valen> the crown part or the silver part away from the copper
[02:22:12] <Valen> i cant really make sense of the image
[02:22:35] <andypugh> it should be a single part, a lid with a locating rim.
[02:22:42] <Valen> Ahh
[02:22:58] <Valen> can you remake the underlying vessel or is that historic also?
[02:24:00] <andypugh> Much more so. It has the name of every President of the club since 1922 engraved on it.
[02:24:06] <Valen> ahh
[02:24:09] <Valen> hmm
[02:24:25] <Valen> I was thinking perhaps machine up a ring of a softer metal (perhaps) then glue it on to the bottom
[02:24:37] <Valen> that way theres no heat involved
[02:25:13] <Valen> softer than the cup tat is
[02:25:14] <andypugh> The lid is (currently) a lot thinner outside the concave curve
[02:25:55] <andypugh> Thing is, the lid gets dropped. The pot is full of beer and is rarely dropped.
[02:26:37] <Valen> dropping the beer is bad for ones health
[02:26:46] <andypugh> I could just turn a sturdy rim from solid pewter and solder it on.
[02:27:09] <Valen> I'd suggest glue, if your worried about heat
[02:27:25] <andypugh> Glue is unauthentic
[02:27:29] <Valen> there are some pretty nifty epoxies
[02:27:47] <Valen> any repair is unauthentic ;-> question is what will damage the underlying material the least
[02:27:56] <andypugh> Ideally I want people in the future to have no idea I ever did anything.
[02:27:59] <Valen> googling pewter, it basically *is* solder
[02:28:54] <Valen> so the temperature control is going to need to be neat
[02:29:26] <andypugh> Yes, a tin lead alloy where the lead preferentially dissolves into alcohol. It's the ideal drinking vessel material :-)
[02:29:35] <Valen> but of course!
[02:29:56] <Valen> spray epoxy line the inside of said cup? ;-> works for cans
[02:33:46] <andypugh> Actually, Wikipedia says that Lead is not a major constituent of pewter, and should be entirely absent from tablewares
[02:34:28] <Valen> current ones
[02:34:38] <Valen> seemed to indicate it may still be around
[02:34:50] <Valen> I'd be using a tin/lead solder though in the repair
[02:35:03] <Valen> mpt is like 220C vs the pewter at 260C
[02:35:15] <Valen> but I'd be really worried about it softening
[02:35:24] <andypugh> If you are drinking 12 pints of beer from a cup, worrying about lead seems inapppropriate
[02:36:04] <Valen> I use tin/lead for my plumbing ;-> I'm not that bothered
[02:36:14] <Valen> but if its easy to avoid, you may as well
[02:37:45] <andypugh> The lid barely touches the contents
[02:38:33] <Valen> you seem to be labouring under the impression i'm against tin/lead solder, I'm saying you must use it in order to not melt the pewter
[02:38:49] <andypugh> But it belongs to one of the worlds foremost technical universities. They can analyse it :-)
[02:39:12] <Valen> I wonder about using something like a woods metal alloy in place of solder
[02:39:36] <andypugh> I would prefer to TIG with an identcal material.

[10:59:20] <RyanS> how do USB motion controllers deal with the limitations of USB?.. e.g. you can't run a gecko G540 via a USB to parallel converter (I've read something about that being too slow or indirect)
[11:08:44] -!- cmorley2 has quit [Ping timeout: 244 seconds]
[11:14:06] <awallin> you can send a stream of commands one-way over usb
[11:14:25] <awallin> the problems are with feedback, i.e. send a command, then quickly get a response, then send the next, etc.
[11:22:09] -!- Valen has quit [Quit: Leaving.]
[11:29:46] <archivist> RyanS, the steps must arrive on time with consistent delay, that cannot happen over usb

[11:37:25] <awallin> archivist, RyanS: don't you think the usb motioncontrollers all send some high-level commands over usb, and have step generation on the usb-board. for open-loop machines that will work. i.e. the lpkf pcb-routers I have used all use something similar-ish to HPGL over RS232. works fine. but no feedback control.
[11:37:59] <RyanS> so USB motion control units like Smoothstepper could mess up the part being machined because the feedback isnt there?
[11:38:12] <cblack30> A good usb motion controller will handle all it's control onboard, only taking simple commands from the host such as "move to 3". For instance in a usb stepper controller the host computer would send a command "move 3000 steps over 1.2s". It would then be up to the usb device to queue up this command and properly output steps to the motors.
[11:39:09] <awallin> any open-loop approach will fail if the motors loose steps
[11:39:58] <RyanS> However most hobbyist CNC routers (which is what I'm looking at) are open-loop stepper based right?
[11:40:58] <awallin> depends on how you define hobbyist... some people in this channel have the cnc-fever pretty bad :)
[11:41:28] <jthornton> and many use cnc for production work
[11:41:43] <awallin> if you are spending 5k on tools vices toolholders etc etc anyway then servos makes a lot of sense
[11:42:00] <RyanS> hmm $3000 < routers I'm talking about
[11:42:02] <cblack30> Most stepper controlled machines are open loop, as long as sized properly you wont have any issues
[11:42:09] <awallin> if you are trying to spend <1k to do some small easy stuff then steppers are a cheaper way to start
[11:42:33] <jthornton> yea you don't want no whimpy stepper driving the Z when you rapid a 1" end mill into the vise
[11:43:08] <awallin> linuxcnc potentially makes the servo option quite similarly priced to a stepper solution..
[11:43:18] -!- bmwyss has quit [Quit: bmwyss]
[11:44:16] <RyanS> so what would be some of the main causes of an open loop system missing steps?
[11:44:18] <cblack30> Hit up ebay, you can easily find used servo motors with drives fairly cheap.
[11:46:04] <awallin> RyanS: steppers can work much better in applications where there are no or little cutting forces, like reprap 3d printer, or a laser cutter. with a mill there are big and variable cutting forces. if the holding torque of the motor is exceeded you loose a step
[11:47:04] <awallin> pcb-milling is another example where the cutting forces are small
[11:47:40] -!- sumpfralle has quit [Ping timeout: 260 seconds]
[11:47:43] <RyanS> servos would be overkill for a wood, plastic & aluminium cutting router of say 600x400mm bed size?
[11:48:21] <awallin> that description doesn't define the cutting forces sufficiently
[11:48:43] <awallin> try spindle power, cutter diameter, depth-of-cut, and feedrate specifications instead
[11:48:58] <archivist> and depends how well constructed it is too
[11:49:24] <archivist> no backlash and play on a servo system
[11:50:30] <cblack30> no backlash?
[11:50:40] <RyanS> hmm 1.5kw, 6mm, conservative cut depth whatever that may be
[11:51:16] <archivist> backlash= play or lost motion in the drive
[11:53:31] <awallin> 1.5kW with a 6mm cutter and 1-2mm width of cut should be ok, at a slow feedrate, in aluminium. if you plan to make parts that need a lot of roughing however get servos..
[11:54:12] <awallin> and that will need lots of coolant, so better build an enclosure for the mill and a re-circulating coolant system
[11:55:21] <awallin> if you stick to plastic and wood just a vacuum cleaner to take away the dust might be enough. bigger parts in aluminium is a completely different world
[11:57:14] <RyanS> essentially the Chinese 6040 with 1.5kw spindle ..... Apparently is prett solid build quality, ball screws , 150N.cm steppers ... it can do some light aluminium machining I've heard, it's primarily a wood router
[11:57:41] <RyanS> and the controller is shit
[11:57:49] <RyanS> however
[11:59:07] <RyanS> Not much Z axis travel :(
[11:59:30] <awallin> so the biggest steppers you can fit/afoord, geckodrives, and linuxcnc over parallel port would be the budget upgrade I think
[11:59:36] <awallin> afford

[12:08:35] <awallin> the psu and switches from that box are probably re-usable. if experience says the control is otherwise bad then a swap for geckordives is probably worth it
[12:10:48] <RyanS> hmm I don't see why you could tram the frame on one of those machines surely there is every chance it could be out of alignment
[12:11:39] <archivist> nothing is perfect, but how good do you need
[12:12:07] <archivist> I wonder what drivers are in the box
[12:14:56] <RyanS> There are some pictures umm, http://www.carving-cnc.com/cnc-diy-accessories/cnc-stepping-drive/t65-3a-stepper-motor-driver.html
[12:15:35] <RyanS> Not really much information
[12:16:22] <archivist> enough to know its a cheaper driver
[12:18:46] <RyanS> There is a thread on CNC zone about it.. I'm surprised there isn't more talk about the quality of the VFD

[14:27:17] <JT-Shop> you asked if I was here
[14:27:39] <andypugh> I did. About 12 hours ago.
[14:28:33] <archivist> time flies
[14:28:57] <JT-Shop> yes, it was a nice long nap
[14:35:25] <JT-Shop> do you still need me for something?
[14:37:43] <andypugh> Just a metal-spinning question
[14:38:02] <andypugh> Did you look at the photo?
[14:38:34] <JT-Shop> no, let me scroll back
[14:38:56] <andypugh> No need

[14:39:36] <JT-Shop> interesting
[14:39:59] <JT-Shop> is the top silver soldered to the dish?
[14:40:01] <andypugh> Someone tried to repair/reinforce the rim by stretching and rolling it round a copper ring, anf that turned out to be rather counterproductive.
[14:40:37] <andypugh> I am trying to figure out how to fix it.
[14:40:38] <JT-Shop> oh I see now, I though it was sitting in a bowl or something
[14:41:19] <JT-Shop> when I was spinning the test parts often I needed a backup tool to keep the wrinkes from forming
[14:42:02] <JT-Shop> as soon as I noticed wrinkels starting I backed up the metal then used my tool to push to the backup and that removed the wrinkles
[14:42:09] <andypugh> I think I will end up cutting off the outer part of the rim and making a new edge to weld/solder on.
[14:42:31] <JT-Shop> what is the material?
[14:42:36] <andypugh> Pewter
[14:43:11] <andypugh> First job, find a source of pewter sheet
[14:43:40] <JT-Shop> have you attempted to use a small hammer to remove the wrinkles yet?
[14:44:48] <andypugh> No, I am planning to look at it and think for a week or so.
[14:44:58] <andypugh> It has a certain history.
[14:45:10] <JT-Shop> that is always a good plan
[14:45:15] <archivist> my local scrap yard tends to keep pewter items as little value, get some from scrap and recast/roll

[14:49:21] <andypugh> I found them, and will send of a query next week.
[14:49:38] <archivist> ah that front page mentions how it is done by centrifugal casting too not spinning
[14:56:10] <andypugh> That lid was spun, I am fairly sure.
[14:59:20] <andypugh> And it seems to be made of two layers. There is a smaller inner lid soldered in.
[14:59:59] <archivist> could it just be a pressing too
[15:04:51] <andypugh> It was made as a one-off so I am fairly sure it is a pressing.
[15:05:08] <andypugh> Sorry, I am fairly sure it is a spinning.
[15:07:22] <andypugh> 8" diamter, by the way. There may be a lack of a sense of scale in the picture.
[15:08:37] <andypugh> In use, to give a sense of scale. http://www.the22club.org/wp-content/gallery/90th-anniversary-dinner/img_6455.jpg

[19:39:18] <IchGuckLive> pcw_home: still strugeling with the servo here no Serial communication to get the motorfile into the drive
[19:39:46] <IchGuckLive> i managed to get some parameters into it so i can access now the Jogmode but then the servo stalls
[19:40:09] <IchGuckLive> it triggers back and foce about 10deg
[19:40:29] <IchGuckLive> if i git jog forward then reward
[19:40:39] <IchGuckLive> if i hit forward forward nothing
[19:41:49] <pcw_home> IS the drive set up for the particular motor/encoder? that would be the first thing (getting commutation right) symptoms of bad commutation are inability to spin the motor
[19:42:00] <IchGuckLive> maybe ishoudt get the encoder signal controlled so the Index is not on the A or B phase
[19:42:51] <IchGuckLive> pcw_home: i did what i think it is wright no other encoder motor connfig work
[19:43:26] <IchGuckLive> the file omron provided is giving me other things but i do not have the omron encoder for the servo
[19:44:13] <IchGuckLive> my main problem is that i now got 4 Servos same type the encoder are all the same but the datashieed gives me a other encoder type
[19:45:08] <IchGuckLive> it is 1 pulse index per rev in the manual and all encoder give me a nice clear serial signal i gess on the encoder index
[19:45:31] <IchGuckLive> so i gess maybe there are A quad B Serial
[19:45:55] <IchGuckLive> or somthing like that or absolute
[19:46:15] <IchGuckLive> i now mounted a standard A/B /Z to the Servo
[19:46:23] <IchGuckLive> and set this connfig up
[19:46:37] <Tom_itx> open collector encoders need pullups
[19:46:48] <IchGuckLive> that gives me after 5+ weeks a sign of Driver allive
[19:49:54] <IchGuckLive> the encoder is Dynapar E222048xx4x01
[19:55:02] <IchGuckLive> i think now that all the servos are ok but i simply got the wrong settings
[19:55:38] <IchGuckLive> as omron delivers costem made Camera Systems they may not have the standard Encoder inside the Servo

[20:02:01] <IchGuckLive> Tom_itx: i fixed some screws now and if i hit jog the servo turns without command slowly but there are only 10rpm in the parameter
[20:02:23] <IchGuckLive> i dont think it shoudt move without command
[20:03:22] <AR_> well, i need to rebuild my cnc
