[00:10:55] <Jymmm> archivist: Heh, right now I'm just working on *a* ham radio; probably going to build a DDS version
[00:11:51] <Loetmichel> Jymmm: for medium wave: just use a program for the PC

[00:13:10] <Jymmm> Loetmichel: Yep, I have one.. rtl-sdr, but that's receive only, no transmit.

[00:13:15] <Loetmichel> it is unsetteling to go in a adjacent room and can hear the played MP3s clearly in the medium wave radio...
[00:13:33] <andypugh> There is a ton of radio stuff in Linux by default
[00:13:36] <Loetmichel> without any transmitting device put on the pc besides its cpu
[00:13:56] <Loetmichel> Jymmm: no, i meant: WITHOUT any transmitter
[00:14:15] <Loetmichel> was a exploit to get keylogger data out of non-internet-PCs
[00:14:52] <Jymmm> Loetmichel: I understand, and that's what rtl-sdr is (google it), they are cheap $20 and nothing more than the dngle, an antenna, and free software is all that's needed.
[00:15:17] <Loetmichel> the cpu will be idle and full load in µs intervals, taht modulates the VCC, that modataes the PSU and the power canble will send it
[00:15:51] <Jymmm> Loetmichel: But, I passed and received me Extra class license last saturday, so I what to build a transceiver so I can get on the air!
[00:16:29] <Loetmichel> hrhr, congratiulations and good luck
[00:16:47] <Jymmm> well, received in FCC database on thursday that is =)
[00:16:54] <Jymmm> Loetmichel: good luck?
[00:17:09] <Loetmichel> in building the transceiver
[00:17:37] <Jymmm> Loetmichel: Well a transmitter is not that hard to build... http://www.sparkbangbuzz.com/easy-ten/easy-ten.htm
[00:17:39] <Loetmichel> you're on of a dying kind
[00:18:11] <Loetmichel> i dont know ANY AFU which builds his equitment himself
[00:18:13] <Jymmm> Loetmichel: Not really... http://www.youtube.com/watch?v=_2HCVP3oKEw
[00:18:45] <Jymmm> Loetmichel: I'm not talking tubes here, though some are into building those.
[00:18:58] <Loetmichel> the old ones who can are dead, and the young ones buy them stuff
[00:19:29] <Jymmm> No, it's just personal preference is all.
[00:19:57] <Jymmm> I want low DC power, tube doens't fit in that category =)
[00:20:31] <Jymmm> Loetmichel: here's another http://www.youtube.com/watch?v=mrDYEbRGEds
[00:20:35] <Loetmichel> oh, i have to coorect that: i know ONE... one of my workers is AFU with a russian license... about 50 years, and constantly rebuilding his Equipment
[00:21:22] <Loetmichel> but the other 10 or so i have met: only bought stuff, not even a selfbuild antenna sometimes
[00:21:56] <Loetmichel> Jymmm: depends on the tubes
[00:22:19] <Loetmichel> there are really nice little russian tubes made for battery power.
[00:22:20] <Jymmm> If that's all they want, sure. It's just like those that just want to engrave PCB's, or build room sized CNC Mill machine like skunkworks__
[00:22:49] <Loetmichel> they are small, steel casing( non breakable) and use very low power for heating
[00:23:31] <Jymmm> Loetmichel: You do relaize some of those are 100V batteries for tubes, right?
[00:24:24] <Loetmichel> Jymmm: thats what electromechanickal converters are for ;-)

[00:29:42] <Jymmm> yep, all by hand too
[00:30:01] <Jymmm> it's frickin amazing watching him make them

[00:39:02] <andypugh> L84Supper: http://www.pico-systems.com/pwmservo.html
[00:39:44] <L84Supper> andypugh, thanks! that looks good
[00:40:20] <Loetmichel> <- bedtime
[00:40:39] <Jymmm> Havne't seen Jon around here in a long time.
[00:40:54] <Jymmm> or JMK for that matter
[00:42:11] <Jymmm> L84Supper: http://pico-systems.com/osc2.5/catalog/product_info.php?products_id=26
[00:43:54] <andypugh> L84Supper: The Mesa 7i29 is similar in spec bout dual-channel for a bit less than twice the price.
[00:44:01] <gmouer> those drives say 20amp but no mention if that is peak or cont. are there more specs somewhere? a friend is looking for something for a bridgeport
[00:44:01] <L84Supper> great, and I can modify it for larget FETS and change the current sense resistor to up the capability to 50A
[00:44:54] <r00t4rd3d> what u gonna use that for?
[00:47:10] <andypugh> gmouer: Pico can sell a complete turnkey conversion for a Bridgeport
[00:47:47] <gmouer> not on their website though?
[00:47:54] -!- rob_h has quit [Ping timeout: 260 seconds]
[00:48:09] <andypugh> Mesa can sell you the components to do the job, or any similar job, but rather less turnkey
[00:48:21] <L84Supper> it's for wheelchair motors used in hackerspace projects
[00:48:34] <r00t4rd3d> lol
[00:48:58] <r00t4rd3d> battlebots
[00:49:09] <L84Supper> yeah, that kind of stuff
[00:49:33] <andypugh> gmouer: http://www.pico-systems.com/largepwm.html
[00:49:42] <r00t4rd3d> i imagine a wheelchair motor is fairly strong
[00:50:37] <r00t4rd3d> or from one of those scooters fat people ride around on
[00:50:39] <L84Supper> somebody asked me about some remote controlled Daleks, i figured somebody must have an off the shelf motor controller for that size motor
[00:50:55] <andypugh> L84Supper: www.4qd.co,uk
[00:51:04] <L84Supper> r00t4rd3d, yeah, it's what they are using
[00:51:12] <andypugh> http://www.4qd.co.uk
[00:51:21] <gmouer> kind of funny, they say for large machines and show a taig as a example
[00:52:01] <gmouer> wonder what those sell for?
[00:52:16] <L84Supper> some of the motors are 36V 50A max
[00:52:17] <andypugh> Yeah. No idea why. The _link_ that page says "Bridgeport" and Jon runs a Brigeport.
[00:52:40] <L84Supper> in the luxury wheel chairs
[00:52:52] <andypugh> My Robotwars robot was 200A max.
[00:53:04] <gmouer> I will pass the info on, a phone call will get him the answer
[00:54:11] <r00t4rd3d> see that tomorrow SpaceX is gonna try and launch a rocket to the space station?
[00:54:39] <andypugh> Actually, 4QD are ideal for wheelchair motors too. That's largely their market, wheelcahirs and golf carts.
[00:55:13] <L84Supper> http://newaycnc.en.alibaba.com/productlist.html if they came factory equipped with LinuxCNC, would people be interested or afraid of them?
[00:56:34] <L84Supper> they currently offer a few different controller with Fanuc being the most popular
[00:59:39] <gmouer> andy, do you have to configure linuxcnc from scratch for those pico drives, or is there a template or similar around?
[00:59:55] <L84Supper> http://www.sundamachinetools.com/ same for this manufacturer
[01:00:15] <gmouer> I am going to do my bridgeport too in a few months, ditching mach totally
[01:01:33] <r00t4rd3d> gmouer, the guy who makes those drives was an early adapter to linuxcnc
[01:01:45] <r00t4rd3d> so i imagine its not to hard to get them working correctly

[01:02:13] <r00t4rd3d> http://www.linuxcnc.org/docs/devel/html/common/emc-history.html
[01:02:33] <andypugh> gmouer: No idea. I have never had anything to do with Pico. I randomly "went Mesa" when I started, then wrote drivers that were missing, got sent samples, wrote more drivers....
[01:02:35] <gmouer> yea, I know pico's are pretty common. There must be some sample code floating around somewhere or a guide
[01:02:39] <r00t4rd3d> Jon Elson = Pico Systems
[01:03:01] <andypugh> There are Pico configs in the standard distribution
[01:03:27] <gmouer> yea, so far I bought 2 mesa setups, a 7i76 and a 7i77
[01:03:33] <andypugh> Any LiveCD comes with Pico confs.
[01:04:50] <gmouer> ha! I just recently installed from the live cd, wonder if they installed to the hard drive when I installed, will have to peek around
[01:05:40] <r00t4rd3d> run stepconf and see if they are listed
[01:05:46] <andypugh> They should be _somewhere_ in the sample configs selector when you start via the picker.
[01:06:20] <gmouer> the price of those drives is certainly right
[01:06:20] <andypugh> r00t4rd3d: They are not stepper drives, nothing to do with Steconf
[01:06:26] <r00t4rd3d> oh
[01:06:57] <gmouer> the bridgeport sem motors like around 15-20amps cont. peak of double would be nice
[01:09:10] <andypugh> Pico PPMC uses the parallel port to talk to an FPGA. It's quite a lot like the Mesa 7i43.
[01:10:02] <andypugh> But there is no reason that you can't use the drives with any other PWM source, including Mesa,
[01:10:59] <gmouer> it would be pretty hard to pry me away from mesa boards now that I have used them
[01:11:07] <andypugh> Well, 7i29 then
[01:11:37] <andypugh> Pricing is pretty much the same when you consider that the 7i29 is 2 channels
[01:13:46] <andypugh> Just check that they can work down at 24V

[01:17:37] <gmouer> here is bridgeport, used pico drives but at the bottom of the page, under servo tuning, he talks about AMC drives, so that is confusing http://igor.chudov.com/projects/Bridgeport-Series-II-Interact-2-CNC-Mill/

[01:22:05] <L84Supper> http://kellycontroller.com/brushless-hub-motors-c-21_62.html anyone ever try anything by Kelly Controls?
[01:22:12] <andypugh> Is it actually possible to buy via Alibaba? I always had the impression that it was aimed at companines selling in container loads.
[01:22:48] <L84Supper> you can order 1-2 depending on the vendor
[01:23:15] <L84Supper> having someone in China to purchase and ship them also helps
[01:24:09] <L84Supper> otherwise it's TT and wait 3+ days for the payment to clear and then it gets shipped, or you have to use an escrow service

[02:47:40] <ScribbleJ> I bought it off ebay, from hongkong.
[02:47:41] <Connor> Is there a standard M20x1.5 fitting for hydraulic/air or something? I have a pump that looks to have a M20x1.5 outlet..
[02:48:02] <tjb1> The mechanical parts look good
[02:48:04] <ScribbleJ> Yea
[02:48:29] <ScribbleJ> It's worth what I paid for it, but it's not ... well, quality.
[02:48:30] <ScribbleJ> heh
[02:48:56] <ScribbleJ> It came with a harmonic drive 4th axis which is cool, too.
[02:49:01] <tjb1> Electronics or linear and drive parts?
[02:49:29] <tjb1> Electronics look pretty shatty
[02:49:51] <ScribbleJ> I'm not sure what that question means. The electronics are pretty lousy, but they do the job. I'd like to at least make a new box for them soon.
[02:50:05] <tjb1> Whats not quality
[02:51:03] <tjb1> Nothing better than a build log with no pictures...

[12:16:52] * jthornton ponders a feed and speed calculator design
[12:17:10] <gmouer> I face milled some the other day, 2" face mill, about .050 doc, stalled the spindle !!! a attention getter, never had that happen before
[12:17:48] <jthornton> yea, that would get your attention fast
[12:17:59] <jthornton> a BP knee mill?
[12:19:19] <gmouer> yes, but in fairness, I leave the head pulley drive set at 3300rpm and let the vfd do all the speed change work, so that facemill running at about 1k rpm was in a area of low motor rpm/not much torque multip by the belt drive etc.
[12:20:01] <gmouer> still, a attention getter !! 4140PH showed that weakness quick
[12:20:38] <jthornton> since converting mine to linuxcnc I've been running the spindle at 1800 and setting the variable pulley to get final rpm
[12:21:14] <gmouer> so you leave the motor rpm constant and vary the mechanical pulley drive?
[12:21:26] <jthornton> I "think" I want to change out the variable speed belt drive and replace it with a timing belt
[12:21:39] <jthornton> yes, to get the best torque out of the motor
[12:22:07] <gmouer> what do you do for program controlled speed settings then?
[12:22:42] <jthornton> I have a GS2 VSD that is controlled by linuxcnc and just put in S1800 as I have to be there to change tools anyway
[12:22:59] <jthornton> so when I change a tool I just dial up the correct speed
[12:23:16] <gmouer> ok, gottcha there are some nice articles and info on timing belt drives for the bp on cnczone
[12:23:35] <jthornton> I've not seen them
[12:23:59] <jthornton> mine is a series 1 with a 1 1/2hp spindle motor
[12:24:03] <gmouer> one of the bp guys made and sold them commercially, he put pics and details in a thread
[12:24:33] <jthornton> any search terms that might get a hit on that?
[12:24:47] <gmouer> ok, close, mine is a 2hp vari speed head, a v2e3 cnc mill, sort of a rare breed
[12:25:24] <jthornton> mine came with an Anilam 3 axis CNC conversion on it
[12:25:28] <gmouer> I am sure I can find it, I will post a link in a bit
[12:25:34] <jthornton> thanks
[12:31:31] <gmouer> peek at post#5 for starters, this is the guy that did it, more details in other threads http://www.cnczone.com/forums/bridgeport_hardinge_mills/55030-varispeed_vfd_conversion.html
[12:31:47] <jthornton> thanks
[12:32:42] <gmouer> that is the nicest conversion I have seen. Very professional
[12:34:03] <jthornton> that is nice and I like the idea of using a poly v belt
[12:35:00] <gmouer> yes, the later bridgeport interact knee mills used a poly belt and fixed drive, they had a dc spindle motor though
[12:35:26] <gmouer> the disk brake in that thread is pretty trick too
[12:35:42] <jthornton> my BP VMC uses poly belt drive on the spindle with a 7.5hp servo drive
[12:35:53] <jthornton> yes that is much nicer than the stock brake
[12:36:11] <gmouer> oh yea, that 308 that I am so jealous over after seeing it
[12:37:07] <gmouer> vmc's that can fit under a garage door are few and far between
[12:41:04] <jthornton> it fit under the normal door with the Z all the way down
[12:42:01] <jthornton> nice, I just found a tutorial on using sqlite with python... just what I was looking for
[12:45:05] <gmouer> being new to linuxcnc, I am using a need to know approach, my head still hurts after sorting out that G10/G68 situation, that is why I am going to mill up some toolholders for the new lathe, it gives the headache a break
[12:45:33] <jthornton> and time to think about it...
[12:46:06] <gmouer> some battles are more bloody than others, I usually win though
[12:46:59] <jthornton> yep, I keep trying till I get what I want or find out that what I wanted was not what I needed
[12:47:52] <gmouer> here is a lathe identical to the one I just finished, got mine for $500 though, thats why I couldn't pass it up http://www.ebay.com/itm/American-Way-Gang-Tool-CNC-Lathe-with-PC-Based-CNC-Control-/330792638933?pt=LH_DefaultDomain_0&hash=item4d04c719d5
[12:48:38] -!- jepler [jepler!~jepler@emc/developer/pdpc.professional.jepler] has joined #linuxcnc
[12:49:22] <jthornton> cool lathe
[12:50:21] <gmouer> didn't need it, still not sure what I am going to do with it, but it was too good to pass up and the retrofit got my feet wet with linuxcnc
[12:50:44] <jthornton> that a 5c collet?
[12:50:49] <gmouer> yes
[12:51:07] <gmouer> under the collet nose is a standard a2-5 spindle mount
[12:52:21] <andypugh> It looks like Tormach are going with Gang Tooling on their lathe. The approach does have some attractions. I guess the only real problem is that you can't use more than 2 tools at the same time as the tailstock.
[12:53:14] <gmouer> I think it all comes down to what kind of work you anticipate doing, gang is great for some things, a pain for others
[12:53:54] <gmouer> on my 14x40 that I retrofitted, I am going to be building a 8 tool auto tool turret for it
[12:54:17] <gmouer> based on those german plans that are around the net, but with some tweaks
[12:55:34] <gmouer> got side tracked for a while when this new lathe fell into my lap though

[14:42:49] <andypugh> I wonder if it could be used for high-reosolution 3D printing?
[14:43:51] <pcw_home> maybe with some kind of height feedback
[14:45:36] <L84Supper> andypugh, it already is
[14:46:04] <andypugh> One day I am sure I will invent something first :-)
[14:46:06] <JT-Shop-2> fired up the grinder spindle and it is super quiet and runs perfect...
[14:46:11] <L84Supper> heh
[14:46:25] <pcw_home> also for fine pitch solder paste
[14:46:26] <andypugh> Grinder spindle motors tend to be a bit special.
[14:46:26] <JT-Shop-2> I don't know how it ran before the way it was wired up
[14:46:41] JT-Shop-2 is now known as JT-Shop
[14:47:14] <Tom_itx> my bud had to replace a ballscrew bearing on his mill. the dealer wanted $1400.00 for one bearing
[14:47:17] <JT-Shop> it's a normal motor more or less with an 0 ring drive
[14:47:20] <Tom_itx> double race
[14:47:39] <L84Supper> pcw_home, 3d printed multilayer PCB's on your desktop are not too far off
[14:47:52] <Tom_itx> i think he finally found one for $700
[14:48:08] <pcw_home> Sounds like the dealer is pocketing a fair proportion
[14:48:22] <Tom_itx> or the bearing quality is higher

[14:48:30] <andypugh> Bearing pricing is crazy. The company my dad worked for routinely got 95% discount off of list price.
[14:48:34] <Tom_itx> or both
[14:48:46] <pcw_home> hey they had that in to 70's (Multiwire)
[14:49:04] <Tom_itx> i forgot to bring the number with me but i did tell him about vxb
[14:49:11] <andypugh> Multiwire is still there, too.
[14:49:18] <Tom_itx> although they didn't stock that one
[14:49:35] <Tom_itx> german bearing
[14:49:49] <Tom_itx> bolem?
[14:49:53] <Tom_itx> i forget the brand
[14:49:57] <JT-Shop> now I need to find a source for bjiur metering blocks
[14:50:45] <L84Supper> pcw_home, we are reducing the cost of conductive ink by 10-100x so it can replace plating, drilling and laminating
[14:51:51] <L84Supper> the optomec aerosol jets are too slow and clumsy to work with for production
[14:53:26] <L84Supper> but it's a nice approach for higher viscosity fluids that can't be deposited with inkjet
[14:53:51] <L84Supper> inkjet 2-20cps, aerosol jet 1-1000 cps
[14:59:11] <pcw_home> Looks like a good thing for solder paste or other metallic emulsions that get sintered (hybrids etc)
[14:59:47] <L84Supper> yes
[15:00:44] <L84Supper> think about being able to print a multilayer PCB on your desk in the same time it takes to print out the layers on your desktop printer for proofing
[15:01:09] <L84Supper> and below 3 mill trace and space
[15:01:47] <pcw_home> nice for protos (as long as you dont need copper for thermal/ conductivity reasons)
[15:02:49] <L84Supper> good for production since the boards can reproduce 0.5-2oz copper on power ad ground layers
[15:03:07] <L84Supper> the conductivity is very close to bulk copper
[15:03:30] <andypugh> L84Supper: Have you seen http://www.hitachi-chemical.com/products_pwb_05.htm ? That basically disposes of the whol concept of layers.
[15:03:44] <L84Supper> the trick has been getting everything into one machine
[15:03:49] <pcw_home> I wonder about production (hard to beat 2d imaging for speed)
[15:04:08] <pcw_home> (like ebeam vs masks)
[15:04:53] <L84Supper> andypugh, yeah, the 3dprinters can print non-planar conductors
[15:05:07] <pcw_home> sounds great for protos or 3D printed objects
[15:05:15] <L84Supper> pcw_home, it's as fast as 2d imaging
[15:05:27] <andypugh> Gadhets with the wires in the structure.
[15:05:41] <pcw_home> you mean seconds per card?
[15:06:06] <L84Supper> so it's actually faster that traditional plate, drill, laminate, etch etc for multilayer
[15:06:18] <L84Supper> that/than
[15:07:42] <L84Supper> the tech has actually been working for a while but it's a big patent minefield holding it back
[15:08:08] -!- factor has quit [Read error: Connection reset by peer]
[15:08:10] <L84Supper> slowing it down actually vs holding it back
[15:10:33] <L84Supper> ~25 microOhms cm vs 1.7 microOhms cm for bulk copper

[15:11:04] <L84Supper> it will probably get closer in the next few years as the process gets improved
[15:11:48] <pcw_home> conductive epoxy for part attach?
[15:13:00] <L84Supper> pcw_home, or even traditional solder paste
[15:13:11] <andypugh> JT-Shop: Worth a try, as is an ultrasonic tank
[15:13:22] <L84Supper> embedding inductors is easy
[15:13:34] <JT-Shop> good idea, my neighbor has an ultrasonic cleaner
[15:13:43] <L84Supper> same for small value capacitors and resistors
[15:14:20] <L84Supper> ultrasonic bonding / welding also works
[15:14:24] <andypugh> <imagines JT getting into a truck to drive 100 miles to the neighbour>
[15:14:46] <JT-Shop> not quite that bad, he lives about a 1/2 mile away
[15:15:31] <pcw_home> metering nozzles plugged?
[15:15:39] <JT-Shop> some are
[15:15:42] <L84Supper> we have been using LinuxCNC so far to control the printers
[15:18:48] <pcw_home> We have a customer doing something related (bigger and cruder though)
[15:18:50] <pcw_home> we thinking of ways to use halstreamer and some mods of the encoder
[15:18:51] <pcw_home> counter to "paint" the data stream out
[15:18:58] <pcw_home> we are thinking
[15:19:04] <L84Supper> at some point we have to settle on whats the best way since it's not a CNC machine but there are lots of similarities

[16:39:48] <skorket> Is there such a thing a laser dial?
[16:40:13] <IchGuckLive> did you hear strange noises of the spindel
[16:40:20] <skorket> IchGuckLive, what's the alternative? I have different work that I want to have done, I need to eyeball the position
[16:40:59] <IchGuckLive> skorket: measuring tape
[16:41:08] <FinboySlick> skorket: And going slow when jogging.
[16:41:12] <IchGuckLive> but that gives you only a idee
[16:41:38] <IchGuckLive> take a pin H7
[16:41:58] <IchGuckLive> move to a final dimension Block
[16:42:15] <IchGuckLive> and turn at min speed 10-50
[16:42:30] <IchGuckLive> jog 0.005
[16:42:39] <IchGuckLive> see what happens
[16:42:50] <skorket> I'm sorry, what is jogging?
[16:43:08] <IchGuckLive> movement by one klick
[16:43:59] <skorket> I don't hear any strange noises from the spindle
[16:44:27] * Loetmichel makes a noodle sieve otu of this aluminium sheets ;-)
[16:44:30] <Loetmichel> out
[16:45:11] <IchGuckLive> skorket: then you are fine
[16:47:02] <pcw_home> I guess brinnelling the spindle bearings is a risk with a crash
[16:47:49] <IchGuckLive> pcw_home: is there a note on your page what liit switches are to use NC is this NPN or PNP
[16:48:07] <IchGuckLive> ormal close
[16:48:11] <IchGuckLive> N
[16:48:37] <pcw_home> PNP (or NC mechanical connected to + power)
[16:49:16] <IchGuckLive> Thanks
[16:49:21] <pcw_home> so normal (safe) condition is a high signal
[16:49:31] <IchGuckLive> i know
[16:49:37] <andypugh> PNP / NPN is something of a misnomer, or at best an umperfect metaphor, for ways to wire limit switches.
[16:50:15] <pcw_home> proximity sensors and the like are often named that way however
[16:51:04] <andypugh> Indeed, but it still bugs me if they clearly aren't made of layers of N-type and P-type.
[16:51:06] <IchGuckLive> one more question pcw_home for treading on lathe with 7i76 what encoder for the spindel do you think to use 100-1024 ppr
[16:51:10] <pcw_home> PNP meaning a sensor with a sourcing output
[16:51:12] <pcw_home> NPN meaning a sensor with a sinking output
[16:51:48] <pcw_home> up to you any should be OK unless you have really high RPM
[16:51:57] <andypugh> IchGuckLive: The higher the better, 7i76 can count fast.
[16:52:19] <IchGuckLive> so i go for 1024
[16:52:20] <L84Supper> do electrons fall or rise faster? :)
[16:52:40] <jthornton> depends on your point of view
[16:52:52] <alex4nder> and the direction of your bias resistors. ;)
[16:52:59] <alex4nder> and/or pushing and pulling
[16:53:00] <L84Supper> haha
[16:53:13] <pcw_home> 1024 PPR is 4096 counts/rev so 7I76 encoder limit is about 30,000 RPM with 1024 PPR
[16:53:34] <pcw_home> (encoder may no go that fast however)
[16:53:55] <IchGuckLive> is there anywhere a example for turret with steppers controlled
[16:55:10] <L84Supper> pcw_home, do you have anything up to 36V 50A in a 7i29 card?
[16:56:04] <skorket> hmm, ok, maybe you guys will have some suggestions. I just measured my runout with a depth indicator pushed into the bit sideways and it looks like it's in the 1-2mil range
[16:56:39] <skorket> I just ran a test though, routing out a PCB with a 25 deg bit and I still wasn't getting traces when the pitch was set to 20 mil
[16:56:53] <skorket> any suggestions on what's happening?
[16:57:33] <pcw_home> L84Supper No, 50A requires pretty special PCB work >1" wide traces even with 2 Oz copper
[16:58:20] <L84Supper> pcw_home, just checking, it comes up from time to time
[16:59:02] <pcw_home> If I just put lower voltage lower on resistance FETS in I would still have a bunch of VIAs that would go
[16:59:14] <L84Supper> yeah big mosfets and #6 conductors
[16:59:26] <L84Supper> yeah, limited by the PCB
[16:59:39] <pcw_home> were doing a 48V 30A drive however (50A peak)
[17:00:16] <pcw_home> its smaller, and uses Fairchilds new dual-cool MOSFETS
[17:00:31] <L84Supper> they are using 24V 20A wheelchair motors and also some 36V 50A from something bigger, maybe a small forklift or electric dolly
[17:01:46] <Tom_itx> or treadmills
[17:02:30] <pcw_home> (this is a brushless drive but we will support brush as well)
[17:02:32] <pcw_home> We will make a higher current one but it gets ugly because
[17:02:34] <pcw_home> you need a daughtercard for the DSP once you get above 2Oz copper
[17:03:04] <L84Supper> 0.0015Ω@VGS=10.0V, is pretty good
[17:03:48] <pcw_home> I think the ones we are using are 2-3 mOhm 60V SO8 footprint
[17:04:19] <L84Supper> ok some are even 0.00099Ω@VGS=10.0V
[17:04:30] <pcw_home> (with a heatsink on top hence the dual cool package))
[17:05:57] <L84Supper> http://kellycontroller.com/24v-brushed-dc-seriespmsep-ex-controller-c-79_80.html found these units as well
[17:10:46] <pcw_home> Yeah at 24V capable MOSFETs are really good and cheap (and you dont have the DV/DT turn on issues like you do at higher voltages) so its good for battery power things but in general lower voltage motors are a pain wiring and connector wise
[17:12:12] <pcw_home> (and power supply wise, which is why you dont see 24V motors on CNC machines very often)
[17:16:10] <IchGuckLive> pcw_home: if i ebay search "Inductive Proximity Sensor Detection Switch PNP" it all sais NO not expected NC

[17:20:54] <andypugh> skorket: The runout might not be the whole story, perhaps the head moves too?
[17:21:14] <pcw_home> They are available, you can do it the other (NO) way as well
[17:22:12] <pcw_home> but 7I76 does need PNP = sourcing sensors unless you want to add an external pullup resistor
[17:22:29] <IchGuckLive> pcw_home: i ask the china man if he has also PNP NC

[18:20:19] <L84Supper> Loetmichel, any suggestions for the fastest B&W laser printer?
[18:20:25] <Loetmichel> no
[18:20:59] <Loetmichel> the fastes i had in my fingers was the HP cp2025, but thats a cheap model
[18:21:02] <FinboySlick> archivist: I thought I had at least that as a reliable reference on this machine but apparently nope...
[18:21:13] <Loetmichel> there ought to be better models out there
[18:21:46] <archivist> FinboySlick, how far out is it, do you have a good reference to try it against
[18:22:00] <L84Supper> Loetmichel, looking at using their optics since they scan so fast and are relatively inexpensive

[18:28:24] <FinboySlick> andypugh: I should have tested it when I bought it.
[18:28:42] <FinboySlick> I'm well out of warranty now.

[18:30:11] <andypugh> Having said that, a mlll should still make things flat even if the ways slope, as long as there is no taper between the ways and the top of the table.
[18:30:44] <FinboySlick> archivist, andypugh: You're both right though. Were it not for the logistics and timing, I'd have just brought it back.
[18:31:10] <andypugh> And if there is taper in the table, then a light skim with a fly cutter should fix it. Possibly bond on a sacrificial top plate (or strips)
[18:31:54] Tom_L is now known as Tom_itx
[18:32:10] <archivist> his column axis is out too so that may produce a dished flat
[18:32:10] <FinboySlick> andypugh: I can't drive a flycutter with this spindle.
[18:32:19] <andypugh> The top-plate idea also works if the tool can't reach all of the table, and it generally can't.
[18:32:33] <FinboySlick> Top plate is what I'm planning on.
[18:32:56] <FinboySlick> I might try lapping the table when I build up the courage to take the whole thing appart.
[18:33:09] <archivist> surface plate and blue and hard work with a scraper
[18:33:37] <L84Supper> FinboySlick, how much taper does it appear to have?
[18:34:08] <andypugh> archivist: Not much help with no reference. And the reference is inside the linear guides
[18:34:12] <FinboySlick> L84Supper: I'm still at a loss on how to measure things reliably. I get different results everywhere so far.
[18:34:28] <archivist> andypugh, for making the surface flat
[18:34:55] <andypugh> If the surface isn't flat, then I would look at having it ground.
[18:36:01] <archivist> but it sounds like there are so many possible faults, correction should be done in the right order else it will be just made worse
[18:36:52] <L84Supper> FinboySlick, even though it's out of warranty have you tried discussing the issues with them?

[18:48:07] * archivist just read Len Shelton's msg on the list re mach3 bugs :)
[18:49:16] <FinboySlick> I'll try to get things so that the vise is setup completely flat, then, with some luck, I'll be able to tweak the Z axis perpendicular to that.
[18:51:13] <archivist> FinboySlick, you can just use an add on plate and mill as large an area flat as you can with a small end mill, then get that flat (may be a saw tooth if spindle axis is tilted)
[18:52:07] <archivist> my first milling machine had a saw tooth on any flat I milled

[20:55:10] <syyl> something a bit over 110k eur
[20:55:21] <FinboySlick> Hehe, okay.
[20:56:11] <syyl> but that machine is awesome :D
[20:56:22] <syyl> cnc router on steroids
[20:58:24] <andypugh> FinboySlick: The smaller Tormach is a little cheaper than the Syil.
[20:58:53] <syyl> i am a bit uncertain about the tormachs
[20:59:10] <syyl> the seem to be a bit like haas, only cheaper..

[21:04:19] <archivist> Im coming to the "use old industrial" as it is generally just built right rather than new machines
[21:04:46] * syyl hugs his deckel
[21:05:13] <archivist> may need the wear "taking out" though
[21:06:11] <syyl> btw, i got my little deckel now running with closed loop stepers in x and y
[21:06:20] <syyl> with glas scales
[21:07:41] <syyl> positioning is better than 1/100mm
[21:08:39] <archivist> I did get to see a deckel once in someones garage..does that count
[21:09:15] <syyl> of course
[21:10:15] <archivist> I dont think it will still be there as the owner said goodbye cruel world
[21:14:12] -!- ve7it has quit [Remote host closed the connection]
[21:19:33] <andypugh> I know a chap with a Deckel. It's lovely
[21:19:45] <archivist> ex boss got himself a Thiel as we were closing down which meant the Adcock and Shipley followed me home
[21:20:14] <archivist> I have see that Deckels pics on his site
[21:20:15] <syyl> thiel is something like the mother of all deckel/mahos
[21:20:46] <archivist> it had surface rust when we went to see it http://www.collection.archivist.info/archive/DJCPD/PD/2009/2009_08_13_Thiele_Milling_Machine/
[21:22:11] <syyl> its a nice, big machine..
[21:22:51] <FinboySlick> Looks rigid too.
[21:23:23] <archivist> £800 iirc plus the transport to get it home
[21:23:55] <toastydeath> i'd buy it for that
[21:24:28] <FinboySlick> I need a place where I can put machines like this. My house is inadequate.
[21:25:38] <archivist> throw the car out of the garage!
[21:25:52] <FinboySlick> BTW, apologies to the whole channel for always bitchin' about my mill... I needed an outlet that actually understands.
[21:26:01] <FinboySlick> Heh, I don't even have a garage.
[21:26:10] <FinboySlick> Besides, this is Canada, I'd need a heated garage.
[21:27:22] <archivist> I have a 10x20ft garage 3 lathes a mill and the hobbing machine and some crap
[21:27:35] <FinboySlick> Anyway, I'll keep fixing my Syil 'till it works. As the experienced guys say: It's not the tools it's how you use 'em.
[21:30:03] <archivist> making something work can be fun and educational
[21:30:57] <FinboySlick> archivist: Well, I bought this thing for educational purposes. I sort of hoped I'd be learning the cnc milling bits though, not the fixing your mill bits. I guess the former is most important though.
