[09:36:41] <Paragon39> Morning All, Does anyone participate in pcb milling? If so what angle router bits do you use?
[09:40:40] -!- Guest85744 [Guest85744!~slime@dslb-088-070-073-127.pools.arcor-ip.net] has parted #emc
[09:40:43] <Paragon39> The reason I ask is that I purchased some 60 degree bits but am having little success with them. In the end I hand ground a broken .8mm tc drill bit with a diamond file which works much better (finer tracks) but is not ideal.

[09:58:10] <TekniQue> 700-013-8 60 router for isolation milling and rub out
[10:04:54] <Paragon39> Thanks Guys... These are the bits I purchased. I guess you pay for what you get! http://cgi.ebay.co.uk/5x-Carbide-PCB-Engraving-Bits-CNC-Router-Tool-60D-0-1mm-/260775707209?pt=UK_Home_Garden_PowerTools_SM&hash=item3cb7718249
[10:05:21] <Jymmm> Paragon39: Those are engraving bits.
[10:05:42] <Jymmm> Paragon39: Like if you were engraving plastic name badges
[10:06:45] <Paragon39> Jymmm: Oh OK... Some website regarding pcb-gcode pointed me to them. Can't remember which one! :-(
[10:07:00] <Jymmm> Paragon39: Like these: http://www.reddingmedical.com/prodimg/Pin%20badges.big.jpg
[10:07:53] <Jymmm> Paragon39: or this: http://www.papersignman.com/images/engraved-nametags-lamicoid.jpg
[10:07:54] <Paragon39> Oh I see... So no good pcb's then... Dam
[10:08:15] <Jymmm> Well, they have a flat on them
[10:08:48] <Paragon39> I guess I can still use them for their intended purpose sometime down the road!
[10:09:10] <Jymmm> "...A pack of five V-shape carbide ***flat bottom*** engraving bits..."
[10:10:09] <Jymmm> Paragon39: Those two other links I gave are what some of the ppl on here are using. I don't recall which is which. Might ask cradek or others.
[10:10:10] <Paragon39> They are advertised as PCB routers on ebay... "5x Carbide PCB Engraving Bits CNC Router Tool 60D 0.1mm"
[10:10:56] <Jymmm> Paragon39: I have a bridge for sale... cheap
[10:11:15] <Paragon39> Brideport?
[10:11:23] <Jymmm> Brooklyn
[10:11:47] <Paragon39> Ok I am interested how much ;-)
[10:11:55] <Jymmm> $20
[10:12:35] <Paragon39> Bit pricey!
[10:12:58] <Jymmm> Includes the water too
[10:13:31] <Paragon39> Mmmm... OK, go on then!
[10:13:49] <Jymmm> They are nice bits btw if you want to engrave in plastics
[10:14:33] <Jymmm> I think I've done as small as 8pt type using them.
[10:14:52] <Jymmm> Ariel 8 or 7 pt
[10:14:54] <Paragon39> Look for some real pcb bits on ebay now or some that are located in the uk.
[10:15:11] <Paragon39> That's not bad!
[10:16:15] <Jymmm> Dont know anythign about them, http://www.crownhill.co.uk/level3.php?cat=52
[10:17:09] <Jymmm> Paragon39: http://www.google.com/search?q=Mechanical+Etching+Bits+UK
[10:17:56] <Paragon39> Thanks Jymmm ... Google.. Now why didn't I think of that ;-)

[10:19:51] <Paragon39> not cheap these bits are they.
[10:20:38] <Paragon39> Im becomming a right tight b%$^ard in my old age ;-)
[10:21:11] <Jymmm> Trade off the cost for the headaches doing it other ways
[10:21:28] <Paragon39> Very true!
[10:21:53] <archivist> make a holder to hand grind
[10:23:30] <Paragon39> I could grind the flat out of the 60d router bits.. worth a try.
[10:25:00] <Paragon39> Have you seen this, it works surprisingly well. http://phk.freebsd.dk/CncPcb/
[10:26:17] <Paragon39> I cut one board without and the with z-probing the z-probe board was distinctly more uniform, at the cost of a longer cycle.

[13:26:19] <MattyMatt> Paragon39: the best pcb milling I've seen was done with a 0.2mm EM
[13:28:47] <MattyMatt> on a specific PCB machine. I certainly wouldn't try that on my plywood machine. I get through enough 0.8mm as it is
[13:32:16] <jthornton> skunkworks: no, we are just starting to grow algae on everything so the deck is slippery
[13:37:14] <MattyMatt> arrr swab the deck
[13:40:10] <MattyMatt> Paragon39: I got these since my usual HK suppllier ran out of 0.8 http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=180650433597. iirc this place has smaller ones too

[15:15:41] <ssi_> hey Connor
[15:15:48] <Connor> heya
[15:16:36] <ssi_> schmitt triggers helped a lot
[15:16:43] <Connor> Did they? Cool
[15:16:45] <ssi_> my opto home switches repeat to about 0.0015 now
[15:17:09] <Connor> That's good.
[15:17:32] <ssi_> yep!
[15:17:34] <Connor> That's probably about the best you can get with stuff we're using.
[15:17:37] <ssi_> agreed
[15:18:12] <Connor> and that's also probably well with in tolerance of your measuring device even.
[15:18:26] <ssi_> maybe
[15:18:31] <ssi_> was using a cheapy dial indicator for that
[15:18:38] <ssi_> I will probably put a tenths DTI on it
[15:18:49] <Connor> That's what I mean... It probably is off itself..
[15:18:51] <ssi_> actually
[15:18:59] <ssi_> no, cause I turned some diameters and measured them
[15:19:01] <ssi_> homing in between
[15:19:08] <ssi_> measured with a tenths mic
[15:19:15] <ssi_> it's homing error ;)
[15:19:20] <ssi_> turned .875 and got .872
[15:19:28] <Connor> ok
[15:19:29] <ssi_> .850 and got .848
[15:19:33] <ssi_> .825 and got .826
[15:19:39] <ssi_> that's acceptable
[15:19:54] <Connor> This on a lathe or mill ?
[15:19:56] <ssi_> lathe
[15:20:00] <ssi_> so 0.0015" radius error
[15:20:01] <Connor> Ah.. okay.
[15:20:34] <Connor> That's more critical than the home sensors for a router then..
[15:20:44] <ssi_> yes, much
[15:20:51] <ssi_> cause I'm counting on knowing where my centerline is
[15:21:10] <ssi_> but what I can do anytime I need to work to tighter tolerance than that is take a test cut and measure
[15:21:13] <ssi_> and then bake in an offset
[15:21:31] <Connor> yea.
[15:21:55] <Connor> The other thing you might try.. is cutting a angle on your flag for the slot sensor..
[15:22:19] <ssi_> my flag is terrible right now
[15:22:21] <skunkworks> can you hook a switch on a cam off the shaft? then hook the 2 switches in series.
[15:22:25] <ssi_> I'm going to mill one out of solid aluminum
[15:22:36] <ssi_> skunkworks: I don't followy ou
[15:22:46] <ssi_> on the X leadscrew you mean?
[15:22:49] <skunkworks> parrallel actually...
[15:22:52] <skunkworks> yes
[15:23:07] <ssi_> better way to do it would be to get an encoder for the axis
[15:23:13] <ssi_> emc will do switch + encoder homing
[15:23:46] <jdhNC> someone had a G0602?
[15:23:50] <ssi_> I was going to do that as my first solution, but the cheapy us digital encoders I can get don't have an index pulse
[15:23:54] <ssi_> I have a g0602 :P
[15:24:09] <ssi_> now that the home switch is repeating as close as it is, I can probably get a 300lpr encoder and use that for homing
[15:24:13] <jdhNC> how much work did you have to do out of the box?
[15:24:19] <Connor> Try having the flag angled as it slides into the slot.. further in it goes.. more of the flag the sensor sees.. might give a little better resolution..
[15:25:04] <ssi_> jdhNC: I made a copy of the X axis thrustbearing mount that has a stepper flange on it, turned a ballscrew for the X axis
[15:25:12] -!- mrsunshine [mrsunshine!~mrsunshin@] has joined #emc
[15:25:14] <ssi_> jdhNC: made a new Z end bearing mount and turned a ballscrew for it
[15:25:27] <ssi_> jdhNC: knocked all the gears out of the gearbox, took one of the end bearing plates and machined it for a leadscrew bearing
[15:25:41] <ssi_> fitted a spindle encoder and home switches
[15:25:53] <ssi_> made a toolpost riser block and fitted a QCTP
[15:26:01] <ssi_> and turned a backplate and mounted a 5C collet chuck
[15:26:15] <jdhNC> you did all the turning on the 602?
[15:26:18] <skunkworks> ssi_: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=102-1307-ND
[15:26:50] <ssi_> skunkworks: that works
[15:27:02] <ssi_> need to see if it'll fit the standard screw pattern on the back of a nema 23 stepper
[15:27:26] <ssi_> jdhNC: just the chuck backplate. I turned the X screw on my big lathe, and I turned the Z screw on my surface grinder
[15:27:41] <ssi_> I'm probably going to go back and turn a new X screw on the 602 and finish grind it on the grinder
[15:27:51] <ssi_> not happy with teh concentricity of the bearing journals on the X screw

[15:34:16] <skunkworks> 2 switches - the other one is on the linear part.
[15:34:32] <ssi_> yea
[15:34:34] <ssi_> makes sense
[15:34:39] <ssi_> I'm gonna grab these encoders though
[15:34:50] <ssi_> seems like it could be handy to have both for homing and for watching for lost steps

[15:36:44] <ssi_> SO WORTH IT
[15:36:48] <skunkworks> yes
[15:36:48] <ssi_> heartily reccomend it
[15:37:00] <ssi_> a friend of mine gave me six ITX Via C3 machines
[15:37:02] <ssi_> they're old and slow
[15:37:03] <anonimasu> my plasma is still dead :S
[15:37:06] <ssi_> too slow to software stepgen
[15:37:06] <skunkworks> I am running 2 5i20's in my conversion/
[15:37:08] <ssi_> so I got the mesa
[15:37:14] <ssi_> so glad I did
[15:37:24] <ssi_> the mesa costs less than buying an atom board
[15:37:28] <ssi_> and is more capable
[15:37:35] <anonimasu> mhm
[15:37:39] <anonimasu> both is perferred :D

[15:38:52] <ssi_> I love that style toolchanger
[15:39:14] <ssi_> yea I've seen this video before
[15:39:18] <ssi_> congrats on that
[15:39:44] <Connor> Holly heck.. How old is that thing ?
[15:40:55] <skunkworks> 60's
[15:41:10] <ssi_> skunkworks: it looks like it preselects the next tool as soon as it makes the toolchange
[15:41:21] <ssi_> are you doing the TXX right after the M6?
[15:41:23] <ssi_> is that how that works?
[15:41:46] <Connor> That big drill bit looked a bit wobbley.
[15:42:04] <skunkworks> ssi_: I programmed it that way
[15:42:13] <skunkworks> Connor: yes - it is bent...
[15:42:36] <ssi_> in the g-code, or in the logic for the toolchange?
[15:42:37] <Connor> didn't make much of a difference in the operation though.
[15:43:39] <skunkworks> gcode for now.. I think one of the programmers is trying to make it read ahead and pre-fetch. Have not looked at that recently though.

[16:04:03] <skunkworks> working great
[16:04:37] <ssi_> I'm really impressed with EMC
[16:04:52] <ssi_> been wanting to get familiar with it for ages, glad I finally did
[16:05:06] <cradek> my little machine has two 5i20 also
[16:05:08] <ssi_> my plasma table's still running mach3, mostly cause the THC is supported
[16:05:11] <cradek> it's easy to run out
[16:05:15] <ssi_> but I'd like to find a way to move it over
[16:05:17] <skunkworks> it is one awesome piece of software!
[16:05:32] <ssi_> absolutely
[16:07:35] <skunkworks> cradek: size doesn't matter :)
[16:08:02] <cradek> skunkworks: I like the size of mine!
[16:08:31] <skunkworks> I would love to have something like that or smaller in the corner of my garage....
[16:08:48] <skunkworks> for those nights I cannot sleep :)
[16:08:57] <ssi_> cradek: what is your machine?
[16:09:24] <cradek> http://timeguy.com/cradek-files/emc/jr.jpg
[16:09:42] <ssi_> "little machine" :P
[16:10:15] <skunkworks> cradek: what are the ceilings?
[16:10:28] <cradek> 8' almost exactly
[16:10:41] <skunkworks> great (I have 10ish')
[16:10:42] <cradek> but 8'4 or so right above the machine
[16:11:27] <cradek> this machine is really nice. if you want a small one, get one of these.
[16:11:44] <skunkworks> right
[16:12:08] <skunkworks> cradek: did you ever figure out your bent shaft issue?
[16:12:25] <cradek> no, I've just ignored it
[16:12:28] <skunkworks> heh
[16:13:11] <skunkworks> I could get the z axis to buzz a little while jogging - so I lowered the p-d a bit and have forgotten about it. (doesn't f-error)
[16:13:49] <cradek> a retrofit is never done, but if it's working it's good enough.
[16:14:05] <skunkworks> iirc f-error is set to .001.
[16:14:18] <skunkworks> right - There are still a bunch of stuff we want to do.

[17:28:58] <Paragon39> I am thinking it is based on this technology:- http://mrsec.wisc.edu/Edetc/nanolab/3D_print/index.html
[17:31:08] <skunkworks> wow - that is wisconsin. they sure do a lot of research at madison (I am in wi)
[17:36:06] <skunkworks> JT-Shop: I thought the normal 1shot did it for one servo cycle if the pulse width was set to 0

[17:38:23] <pcw_home> anonimasu so maybe you will have to start isolating noise a bit at at time to see how it gets into the electronics box
[17:38:25] <pcw_home> step motor wires can be pot through a ferrite bead (2 wires = one step motor winding per bead for common mode choke)
[17:38:26] <pcw_home> switch wires can be put through a common bead, nastier things like start relay can go through a RF choke (facing noise source) an then capacitor to ground

[17:48:48] <anonimasu> I think I have a pack of them somewhere
[17:52:28] <Jymmm> anonimasu: did you wrap the relay wire like I suggested?

[17:53:10] <anonimasu> no, I didnt, I forgot
[17:53:52] <Jymmm> the diameter of the core realy doens't matter too much, 1/2" or there abouts.

[17:55:16] <anonimasu> do I stick them close to the controller
[17:55:18] <Jymmm> no metal pipes and such.
[17:55:22] <anonimasu> wire straight through?
[17:55:41] <anonimasu> for the ferrite cores
[17:56:33] <Jymmm> I'm not talking ferrite cores, I'm talking air core.
[17:56:41] <anonimasu> well, I can try that also, while at it
[17:56:48] <anonimasu> but it seems all other stuff is the problem also
[17:57:58] <Jymmm> Coiling the wire around an air core created an RF choke.
[17:58:05] <Jymmm> creates
[17:58:35] <Jymmm> Typically used with coax, but can be used for other purposes.
[17:58:58] <Jymmm> Most wrap around a chunk of pvc pipe
[17:59:28] <Jymmm> 6 to 8 turns, but 10 turns won't do any harm
[17:59:35] <anonimasu> hehe, I cant do that with my wire
[17:59:38] <anonimasu> it's very thick..
[17:59:51] <Jymmm> then get a bigger pipe

[18:36:18] <Paragon39> My brothering law just accidentaly put a little window cleaner in his engine mistakenly thinking it was oil. He called the Audi Stealer and was quoted a 1000ukp to remedy the situation :-0
[18:36:45] <Paragon39> :-0 was meant to be the other one with the wide open mouth!
[18:36:55] <jdhNC> I hesitate to say your brother is an idiot, but...
[18:37:17] <L84Supper> how much is a little?
[18:37:45] <jdhNC> how much could it be... let it run for a few minutes then change the oil
[18:38:35] <L84Supper> exactly, I just got through rebuilding an engine that blew a head gasket, it must have had a quart of coolant in the oil and it caused no problems
[18:38:53] <Paragon39> Brothering Law... Not disputing that ;-) In fairness the bottle was the same colour and size. Apparently it was very little.
[18:38:55] <jdhNC> how much oil did it have in the coolant?
[18:39:14] <jdhNC> for 'very little', I don't even think I'd change the oil.
[18:39:17] -!- acemi [acemi!~acemi@unaffiliated/acemi] has joined #emc
[18:39:21] <cradek> seems like it would just drain out. you could even pour a couple quarts through (drain plug open) to help flush it.
[18:39:37] <cradek> and he can have that advice for only UKP500.
[18:40:13] <L84Supper> now corn syrup or cain sugar, that's fun
[18:40:40] <amperbiguous> The car is scrapped... I suggest he sell me the car. I would begrudgingly deal with it...
[18:40:52] <Paragon39> I think it was a case of tipping the bottle and like thinking oh sh*t that not the colour of oil! DUH
[18:41:39] <amperbiguous> though really: just flush it and consider the engine "cleaner" after the fact. ;)
[18:42:08] <Jymmm> Connor: what is what used for?
[18:42:15] <Connor> yea..
[18:43:34] <Paragon39> Well he seems quite concerned as fairly late model. I suggested DIY change OIL filter (probably not necessary) and flush with 10watt oil mixed with a little Kerosene. But I think quickfit quoted hime like £50 or somthing. Big F'ing difference!

[18:48:27] <awallin_> hiwin? don't know who resells them online cheap...
[18:48:40] <Jymmm> I'd think the water in the window cleaner would just evaporate off at engine temp. Just do an oil change to prevent the soap from breaking down the oil. Besides, don't they have 'detergent' oils these days?

[18:49:58] <Paragon39> Thats with the nut...
[18:50:17] <mrsunshine> hmm, with ballnuts, they have a standard backlasn of 0.00 - 0.05mm it seems, if i would put oversized balls in that, could that be reduced even more? :)
[18:50:26] <mrsunshine> is it possible to put oversized balls in a new ballnut and ballscrew?
[18:50:30] <JT-Shop> the "pulse generator" part threw me off
[18:51:18] <Jymmm> mrsunshine: Not OVERsized, but larger balls. If you had a big supply of various sizes. It's called "hand loading"
[18:51:26] <Jymmm> mrsunshine: Where you at?
[18:51:41] <mrsunshine> sweden
[18:52:13] <Jymmm> mrsunshine: Oh, nevermind then. I know of a place that will let you hand load yourself and you just pay for what you use.
[18:52:43] <mrsunshine> everything is so damn expensive in sweden :(
[18:52:51] <mrsunshine> taxed to death
[18:52:52] <cradek> some high quality screws have two nuts (even with two circuits each) with a spacer between them. then you can adjust the play with a surface grinder.
[18:52:53] <mrsunshine> this country
[18:53:22] <Paragon39> Never thought of using slightly larger balls :-)
[18:53:28] <Jymmm> Though, having a kevlar vest wouldn't be a bad thing to wear with you. It's in an "unique" location.
[18:53:59] <Paragon39> mrsunshine: Especially booze!
[18:53:59] <mrsunshine> Jymmm, but thats what i ment realy, putting 4.01 balls insted of "standard" 4 balls for example
[18:54:20] <cradek> I have done exactly that
[18:54:21] <jdhNC> how can you put in 1/100th of a ball
[18:54:33] <Jymmm> mrsunshine: Yes, that's "hand loading" the ballnut, instead of just machine factory automated loading.
[18:55:03] <mrsunshine> 68 for both ballnut and ballscrew wasnt so bad =)

[19:13:01] <jdhNC> you could use an LED for the receiver also
[19:13:44] <anonimasu> cost is not really the big issue I need it working for work...
[19:13:56] <Paragon39> jdhNC: LED for receiver.. interested how that functons!
[19:14:42] <jdhNC> Paragon: google it, or check http://en.wikipedia.org/wiki/LED_circuit#LED_as_light_sensor
[19:14:57] <Paragon39> will do.
[19:15:00] <mrsunshine> Paragon39, ahh, he had a couple of sizes =)
[19:15:28] <Jymmm> Paragon39: http://cs.nyu.edu/~jhan/ledtouch/ watch the video
[19:16:13] <mrsunshine> Paragon39, but only sends in the uk? :/
[19:16:41] <PCW> Another possible HF ground loop source is the PC power, A line filter may help here

[19:17:33] <mrsunshine> hmm, i should get myself some money, as i want to drive throught the uk and see the countryside etc there, why not just make a turn and throw in some ballscrews at the same time :P
[19:19:06] <Paragon39> mrsunshine: Try contacting seller to ask if he can send to you. If you get stuck let me know as I maybe able to forward on.
[19:19:30] <mrsunshine> Paragon39, haha, and you just keep them for yourself! :P
[19:19:39] <mrsunshine> is Paragon39 a frequenter here? :P
[19:19:47] <Paragon39> I'll keep the nut!
[19:19:59] <mrsunshine> haha :P

[19:20:52] <Paragon39> Well I never... re: LED receiver
[19:21:04] <skunkworks> PCW: maybe a good surge suppressor - the better ones have decent filtering
[19:21:53] <anonimasu> I have a spare ups...
[19:21:56] <anonimasu> maybe that would help
[19:21:56] <Paragon39> mrsunshine: No one answered ... lol
[19:22:02] <mrsunshine> Paragon39, =)
[19:22:57] <mrsunshine> oh well, no rush to upgrade the mill, maybe i get another one in the meanwhile and start working on that insted :P

[19:25:05] <andypugh> Yo! JT-Shop! I am running that code now. Only problem is it is for a 12mm cutter, and I bought a 10mm. :-)
[19:25:06] -!- e-jones has quit [Quit: Ex-Chat]
[19:25:58] <andypugh> Also, the MDF is going really raggedy. I can see I might have to soak it in some kind of bonding agent before sanding.
[19:27:14] <andypugh> I do have a plan B, while pondering the MDF I spotted a big block of rigid protoyping foam that I liberated from work. Doh!
[19:27:33] <JT-Shop> andypugh: give me a minute or three
[19:28:03] <andypugh> I have also learned that 10mm Z steps would probably be fine for roughing :-)
[19:28:13] <JT-Shop> ok
[19:28:48] <JT-Shop> you doing the outside?
[19:29:43] <andypugh> Yes, it's running unattended now.
[19:30:07] <andypugh> I reckon that the 1mm on radius will be fine to take up on the finish cuts.
[19:30:51] <JT-Shop> ok, so you only need the planar finish fixed for 10mm
[19:31:04] <mrsunshine> when milling metal, is high or low rpms usaly used?
[19:31:04] <anonimasu> awallin_: you there?
[19:31:06] <andypugh> Yes.
[19:31:11] <mrsunshine> in what range is a "safe" range to have?
[19:31:14] <mrsunshine> 2k ? 3k ?
[19:31:16] <andypugh> mrsunshine: Correct rpms.
[19:31:23] <anonimasu> did anyone play with interferometery?
[19:31:34] <andypugh> anonimasu: In passing.
[19:31:44] <anonimasu> andypugh: how did it work out?
[19:32:01] <anonimasu> is it possible to diy something that will give a decent resolution?
[19:32:06] <mrsunshine> andypugh, that is, i want to set a maximum rpm my spindle can go to .. so for using 2 - 12mm endmills =)
[19:32:13] <anonimasu> I mean, I cant measure less then 0.01mm for scraping and stuff..
[19:33:05] <andypugh> mrsunshine: Surface speed (rpm x diameter) is pretty much constant. Carbide tooling you might use 70m/min for steel, 120m/min for Aluminium. (Unless those numbers are mm/sec...)
[19:33:10] <JT-Shop> andypugh: I just sent planar finish Y, I'll do the inside in a bit
[19:33:15] <andypugh> Thanks.
[19:33:26] <andypugh> anonimasu: Blue is 0.001"
[19:33:49] <anonimasu> blue?
[19:33:52] <andypugh> You use a reference surface and Ble.
[19:34:05] <andypugh> (Engineer's Blue)
[19:34:07] <anonimasu> yeah, I know, but I have trouble finding a plate..
[19:34:17] <ssi_> prussian blue :D
[19:34:27] <andypugh> http://en.wikipedia.org/wiki/Engineer%27s_blue
[19:34:42] <anonimasu> I have a can of that but no plate
[19:34:46] <andypugh> You could make a plate, by scraping...
[19:34:49] <anonimasu> hence why im wondering...
[19:35:02] <ssi_> or you could buy a plate for like $40
[19:35:05] <cradek> you can't make one plate, but you can make three
[19:35:12] <anonimasu> work has one but it's like the unicorn everyone knows it exists but nobody knows where
[19:35:18] <anonimasu> :D
[19:35:18] <andypugh> Can? I think you have the wrong stuff. Blue is an oily paste, comes in a tin or a tube.
[19:35:20] <ssi_> how big do you need?
[19:35:29] <anonimasu> it says engineers blue
[19:35:30] <Paragon39> cradek: you beat me to it...
[19:35:32] <anonimasu> :)
[19:35:49] <anonimasu> ordered from the us... it's oily like hell and if you get it on your hands enjoy being blue for 2-3 days
[19:36:20] <ssi_> scraping blue is in tubes when I've seen it
[19:36:24] <andypugh> anonimasu: Wikipedia says: When Prussian blue is mixed with http://en.wikipedia.org/wiki/Methylated_spirit it forms a quick drying stain which is known as http://en.wikipedia.org/wiki/Marking_blue or layout dye. This stain is used in the http://en.wikipedia.org/wiki/Marking_out operation in metalworking. Both the "marking out" blue, and the "scraping blue" may be referred to as engineer's blue, which can lead to substantial
[19:36:24] <andypugh> confusion.
[19:36:25] <anonimasu> tho, for scraping on the machine measuring the surface while scraping with interferometery would be easier
[19:36:26] <ssi_> layout blue is in cans, or spraycans
[19:37:03] <anonimasu> http://www.rdgtools.co.uk/acatalog/43935.jpg
[19:37:06] <anonimasu> that kind of blue :)
[19:38:19] <andypugh> anonimasu: That's exactly the right stuff.
[19:38:30] <andypugh> In fact, have you stolen mine>
[19:38:34] <ssi_> haha
[19:38:46] <anonimasu> tho, as i cant find my plate im looking for options
[19:38:48] <anonimasu> :)
[19:38:50] <anonimasu> laser...
[19:39:09] <ssi_> anonimasu: how big a surface do you need

[19:39:25] <anonimasu> very very straight...

[19:39:48] <ssi_> heh
[19:39:57] <ssi_> maybe not the best supplier for you
[19:40:00] <ssi_> but point stands
[19:40:03] <anonimasu> did i mention I pay 250 for shipping
[19:40:04] <ssi_> 12x18" for $40?
[19:40:15] <anonimasu> and 0.002" is shit.
[19:40:21] <ssi_> .0002"?
[19:40:33] <anonimasu> I'd rather pay for a grade 0 plate with 6um per 100mm...
[19:40:34] <anonimasu> :)
[19:40:55] <ssi_> have at it
[19:41:09] <anonimasu> shipping that here is like 250$

[20:12:21] <andypugh> It is about 85% of the way through the thickness, but it is becoming increasingly inefficient, doing lots of rapid-to-clear, running of to the other end of the work, feeding down at cutting rate to the depth, having a quick dab, then rapid out again. Not the most optimised toolpath it seems.
[20:15:13] <JT-Shop> no, OneCNC has a bad habit of cutting lots of air :/

[21:08:04] <ssi> tiny mill
[21:08:15] <ssi> Connor: I wouldn't get anything bigger than a 4" vise
[21:08:19] <Connor> Not so tinny. It's a desktop mill
[21:08:24] <Connor> larger than a X2.
[21:08:25] <Connor> http://www.grizzly.com/products/Drill-Mill-with-Stand/G0704
[21:08:30] <ssi> Connor: get a set of R8 collets
[21:08:39] <ssi> 3/4" and 1/2" endmills are good choice

[21:11:55] <ssi> I thinkthat's probably a good size and value for the 704
[21:12:03] <JT-Shop> ssi that is better than the mill LOL
[21:12:14] <Bridgeport2> good afternoon group My question is I have a short program that loads the tool and turns the spindle on then has some short moves and then the part is done so i move out of the way and leave the spindle run so i can load the next part
[21:12:16] <Bridgeport2> when icycle start the machine the spindle goes off for a split second when it gets to the tool change line but i am using the active tool so no tool change .
[21:12:16] <ssi> I don't believe in cheap vises :)
[21:12:17] <Bridgeport2> this spike is tosting by brake and the vfd .
[21:12:19] <Bridgeport2> why does it try to stop and how can i fix this
[21:12:28] <ssi> the glacern's a good inexpensive vise
[21:12:30] <Connor> I'm on a budget. :)
[21:12:36] <ssi> I have a 4" double kurt on my bridgy
[21:12:42] <ssi> but I paid $275 for it on ebay, damaged

[21:13:48] <Connor> I might be able to swith the collets and that 20 pc end mill set.. I may have to use my drill press vise for a bit.
[21:13:55] <andypugh> (so it's totally useless)
[21:14:04] <Connor> swing..
[21:14:06] <ssi> can't get jaws for it?
[21:14:09] <andypugh> Hi Bridgeport2
[21:14:15] <JT-Shop> oh no don't buy any endmills from the Griz
[21:14:31] <andypugh> ssi: Jaws are something crazy like $700
[21:14:38] <ssi> wtf
[21:15:02] <JT-Shop> I don't see any vises on the Griz
[21:15:03] <Connor> I've got a set of 3/8" hold down clamps coming from Harbor freight.. got 25% off.

[21:15:38] <JT-Shop> I would not get that one for my drill press
[21:16:00] <ssi> Connor: there are things worth saving money on
[21:16:03] <andypugh> Bridgeport2: You could set the "Toolchange with spindle on" parameter..
[21:16:06] <ssi> and there are things that you just need to man up and spend a bit
[21:16:14] <ssi> now, I agree that spending $1k on a kurt is rough
[21:16:19] <ssi> but buy that stinkin $200 glacern
[21:16:21] <ssi> you won't regret it
[21:16:24] <ssi> vises are important
[21:16:31] <ssi> you can't make accurate repeatable parts with a crap vise
[21:17:10] <Connor> ssi: I agree.. but.. I'm doing this as a hobby... Barely swinging the $$$ for the mill.. I can buy add-ons later.. I just need the bare bones to get started and buy the other stuff one-sy two-sy at a time.
[21:17:11] <ssi> don't bother with the swivel base
[21:17:19] <JT-Shop> guys you have to remember this is a Griz mill it's not going to be real accurate anyway
[21:17:21] <Bridgeport2> I thought the tool change had no effect if it was calling the current tool
[21:17:22] <ssi> I'm doing it as a hobby too
[21:17:28] <andypugh> Bridgeport2: It's a parameter in the INI file: http://www.linuxcnc.org/docview/html/config_ini_config.html#sub:%5BEMCIO%5D-Section
[21:17:42] <ssi> JT-Shop: the mill is surprisingly nice
[21:17:43] <andypugh> (you can always change it back after this job).
[21:18:21] <ssi> I wish glacern had a 4" premium
[21:18:23] <JT-Shop> yea, I live a few hours from Griz and have been there looking at the machinery many times
[21:18:25] <ssi> flat-sided so you can mount it on edge
[21:18:34] <Connor> Grizzy sell's it.. but, it's made by someone else..
[21:18:40] <Connor> http://www.machinetoolonline.com/PM-MV-BenchMills.html
[21:18:42] <JT-Shop> China
[21:18:48] <andypugh> Another thought, what does your toolchange line say? and do you have anything hooked up to the toolchange logic? I thought that the entire toolchange sequence was skipped if you had the correct tool loaded.
[21:19:22] <ssi> I'm just sayin
[21:19:27] <ssi> it's not worth buying a $140 crap vise
[21:19:31] <ssi> when you can buy a $220 good vise
[21:19:51] <ssi> not enough discrepancy in price to warrant sacrificing
[21:19:51] <andypugh> No, but I am so far happy enough with my reworked $20 vice.
[21:19:52] <Connor> BF20's, come from the Weiss plant.
[21:20:06] <Bridgeport2> that is what i thought also the line is t14 m6
[21:20:08] <JT-Shop> Connor: any idea why my php works on the hosted site and not on my local machine? I have LAMP installed and can do everything else but the tables won't load from the php....
[21:20:49] <Connor> JT-Shop: you get any errors?
[21:20:51] <andypugh> Bridgeport2: Any logic in the HAL file, or just the normal hal_manualtoolchange stuff?
[21:21:08] <andypugh> JT-Shop: At a guess, permissions?
[21:21:17] <JT-Shop> no, I just get the page that says your database can't be found

[21:21:44] -!- MOGLI [MOGLI!~MOGLI@] has joined #emc
[21:21:49] <Connor> Oh. Could be that the php config file needs to be updated with IP of your SQL server.
[21:22:01] <Bridgeport2> i will have to look at how Kim K set things up but it is a manual tool change
[21:22:17] <JT-Shop> ok, that might be it then
[21:22:19] <Connor> or your LAMP doesn't have SQL started, or, SQL permissions, or Firewall.
[21:22:32] <Connor> could be a few different things.
[21:23:10] <JT-Shop> I think it is the IP of the SQL server... any way to make it "know" if it started from http://localhost ?
[21:24:27] <Bridgeport2> can you verify that the line should be ignored if it calls the current tool or am i missunderstanding what is supposto take place?
[21:25:09] <Connor> You might be able to write a few lines that can check the host name of the machine.. and set the IP correctly.. or, just cheat and modify your hosts file and add the same machine name in pointed to that the live server uses.
[21:26:02] <atom1> php?
[21:26:34] <Connor> Yea, he's asking me about some webpage stuff running on a linux box with apache and php
[21:26:43] <atom1> ser = $_SERVER["HTTP_HOST"];
[21:26:45] <atom1> what's that do?
[21:26:57] <atom1> $theuri = $_SERVER['REQUEST_URI'];
[21:26:59] <atom1> and that
[21:27:05] <atom1> i use them but forgot why
[21:27:12] <Connor> gets you the host name the person typed in to get to the site.
[21:27:26] <Connor> the 2nd one that is.
[21:27:30] <andypugh> Bridgeport2: Mharberler is your man for toolchange as he is busily rewriting it.
[21:27:44] <JT-Shop> Connor: thanks
[21:27:55] <andypugh> mhaberler: I mean
[21:28:06] <mhaberler> hi!
[21:28:17] <Connor> URI gets you the page name.. host gets the host header name.
[21:28:38] <Connor> so www.domain.com/page1.html HOST would be www.domain.com and URI would be /page1.html
[21:28:52] <andypugh> Bridgeport2: Do you have a way to check that TOLCHANGE_WITH_SPINDLE_ON idea without blowing up another VFD?
[21:29:03] <Connor> Okay. so.. back to this.. getting the mill and that set of collets from Grizzly.. anything else ?
[21:29:35] <andypugh> Connor: You could consider not getting the collets, and going for the Tormach R8 toolchanger instead.
[21:29:59] <Connor> Umm.. yea.. how much ?
[21:30:04] <andypugh> R8 is rather long, and that mill is quite small.
[21:30:31] <andypugh> It's a manual toolchanger, just shorter and with repeatable Z-height.
[21:31:08] <andypugh> http://www.tormach.com/Product_TTS2.html
[21:31:21] <Bridgeport2> well if the spindle stays on that is a good thing and if i try it 1 or 2 times it wont hurt things but i have 200 parts to run at 106 second each and dont want it trying to stop and then start all the time it over heated the last vfd :( $300
[21:32:02] <Connor> Order that from where.. and what's the cost?
[21:33:13] <andypugh> You can buy direct from Tormach, but a) I have no idea how good it actually is, and b) it isn't cheap.
[21:33:36] <andypugh> http://www.tormach.com/Product_TTS_sets.html
[21:34:27] <Connor> Umm.. Yea.. not happening any time soon. :)
[21:35:05] <andypugh> But I know that MT3 is annoyingly long, and R8 is even longer. Less of an issue on a CNC mill where you can move away and back easily, but a pain on a manual when you have to move the work out of the way to drop the tooling out.
[21:35:48] <Connor> yea.. again,, bare bones.. I have no machining eq except for a drill press and grill press vise..
[21:36:02] <Connor> and a old sears milling table that's too big to fit on my drill press.
[21:36:14] <andypugh> Bridgeport2: Try the SPINDLE setting for the time being then, it's just an INI file change. (might be annoying when you do need to change tools though)
[21:37:02] <Connor> and what's wrong with Grizzly end mill set 69760 ?
[21:37:05] <andypugh> mhaberler: Do you know if the spindle is meant to briefly stop and restart during an M6 even if the same tool is requested again?
[21:37:10] <Connor> G9760
[21:37:27] <mhaberler> you mean with vanilla iocontrol change?
[21:37:34] <Bridgeport2> am i correct in thinking that the line should be ignored if the tool is current?
[21:38:16] <andypugh> mhaberler: Yes. I am only asking you as I know you have looked at it before tearing it up and starting again.
[21:38:33] <mhaberler> hold on..
[21:39:37] <andypugh> Personally, I never buy anything TiN coated as I think it is just something they do to make poor quality tools look blingy. The really expensive cutters don't tend to have it.
[21:40:34] <ssi> andypugh: yea, I agree
[21:40:49] <Connor> Well.. it'll be till may something till I get my mill.. So.. I'll order it and the collets.. and wait on the endmill and vise I guess.
[21:40:51] <ssi> the only TiN endmills I have are either cruddy chinese ones or $100 each solid carbide
[21:40:58] <andypugh> Connor: Boring heads are really useful. While you are CNC-converting they are ideal for boring bearing housings and then the mill makes it easy to get the centre distances right.
[21:41:13] <ssi> yes, can't live without my boring head
[21:41:15] <ssi> get some cheapy parallels
[21:41:20] <ssi> a spotting drill
[21:41:40] <Connor> http://www.grizzly.com/products/4-pc-Center-Drill-Set-60-/H5930
[21:41:41] <Connor> those ?
[21:41:49] <ssi> nonono
[21:41:51] <ssi> lemme find one for ya
[21:42:16] <ssi> http://www.use-enco.com/CGI/INSRIT?PARTPG=INSRAR2&PMAKA=891-4247&PMPXNO=3904228
[21:42:16] <Connor> Harbor freight has parallels I think..
[21:42:18] <andypugh> (I use centre drills :-)
[21:42:20] <ssi> yes, they do
[21:42:24] <ssi> centre drills work
[21:42:27] <ssi> but I really prefer spotting drills
[21:42:39] <ssi> and that just happens to be a $14 US example
[21:42:41] <ssi> for the picture :)
[21:42:49] <ssi> they can be had cheaper hahah
[21:42:54] <mhaberler> andypugh: using iocontrol: spindle is still turned off if tool already loaded
[21:43:05] <ssi> I've got a solid carbide spotting drill that I bust out for hard work
[21:43:37] <andypugh> mhaberler: Even with the SPINDLE_ON_DURING_TOOLCHANGE ini file option
[21:43:39] <andypugh> ?
[21:43:49] <ssi> ok so how do folks go about doing VFD interface with a 7i43?
[21:43:54] <mhaberler> hold on..
[21:44:34] <andypugh> My centre drills were cheap from eBay. Too cheap, they are eccentric and waggle the head of mt flimsy mill...
[21:45:02] <andypugh> ssi: simplest, cap and resistor
[21:45:06] <Bridgeport2> I would check my BP II but it is 12 miles away right now
[21:45:08] <ssi> and then what, PWM?
[21:45:17] <andypugh> yes
[21:45:26] <ssi> works fairly well?
[21:45:32] <mhaberler> anypugh: in that case it wont turn it off; the only difference is that iocontrol wont rais the tool-change signal and hence not wait for tool-changed
[21:45:56] <Connor> Oh, Edge finder.. this set.. http://www.grizzly.com/products/4-pc-Edge-Finder-Set/H5556 or this set.. http://www.grizzly.com/products/4-pc-Edge-Finder-Set/H2939
[21:45:58] <mhaberler> the interpreter execution and canon commands are all the same
[21:46:10] <andypugh> ssi: WHat I actually have is an isolated DC-DC convertor, and a precision current source, and an op amp. But it isn't very good.
[21:46:13] <ssi> Connor: tbh, I just use my spotting drill as an edge finder
[21:46:24] <ssi> andypugh: what's not good about it?

[21:46:58] <ssi> I see
[21:47:15] <Bridgeport2> So in manual tool change i dont need it to pause and it will continue on with the motion and cut
[21:47:23] <andypugh> However, it does give you 0-10v from a 5V PWM
[21:48:27] <ssi> my VFD and 3-phase motor for the lathe came in today
[21:48:34] <ssi> I dunno if i have it in me to get it all running tonight
[21:49:36] <Connor> I'm thinking the H5556 set.
[21:49:37] <andypugh> I feel like some weird middle-man here. mhaberler, have you noticed that the toolchange query is really from Bridgeport2

[21:49:55] <ssi> Connor: agreed
[21:49:59] <mhaberler> ok
[21:50:16] <andypugh> ssi: It is possible that the VFD might be happy with a PWM input, check the manual.
[21:50:20] <Connor> It has 6 wiggler ends vs 5
[21:50:57] <ssi> I'm realizing that the VFD I got is 120VAC input only

[21:51:17] <ssi> which is simultaniously good, because it means I don't need to install a new 230VAC line
[21:51:25] <ssi> and maybe bad, cause I lose flexibility
[21:51:32] <JT-Shop> you will find you only need one edge finder with one squiggley end
[21:51:57] <Connor> same price either way.. with 4 different ones. :)
[21:53:17] <JT-Shop> for $2 you can get a good one http://www1.mscdirect.com/cgi/NNSRIT2?PMAKA=86425246&PMPXNO=2222918&cm_re=ItemDetail-_-ResultListing-_-SearchResults
[21:53:20] <JT-Shop> more
[21:57:14] <JT-Shop> but I've not used it in so long I don't even know where it is :)
[21:57:15] <Connor> don't forget shipping charges
[21:57:34] <ssi> just get the ones from grizzly
[21:57:40] <ssi> maybe you'll use them more than I did :P
[21:57:55] <JT-Shop> really you don't even need one
[21:58:04] <ssi> nope
[21:58:19] <ssi> btw, something you're going to quickly figure out with this stuff
[21:58:24] <ssi> tooling costs way more than the machine
[21:58:29] <ssi> and you can't avoid it
[21:58:29] <Connor> OKay. the machine, collects, center drills, and edge finder.. Total to my door WITH liftgate service 1234.40
[21:58:47] <Connor> ssi: Oh.. I know.
[21:59:07] <Connor> I've spent years massing tools for electronics and general tools...
[21:59:25] <ssi> also
[21:59:26] <Connor> Anyone have a coupon code for grizzly?
[21:59:27] <ssi> "massing" is a good term
[21:59:34] <ssi> cause most of this tooling will be heavy ;)

[22:02:40] <JT-Shop> I'd drop the center drills and edge finders and get a set of parallels
[22:03:05] <Connor> I'll get the parallels from local Harbor freight.
[22:03:10] <Connor> with 20% coupon
[22:03:15] <JT-Shop> there you go
[22:03:25] <andypugh> Anyone tried the wavy parallels?
[22:03:26] <JT-Shop> do you have any way to measure parts?
[22:03:42] <Connor> I have digital calipaers
[22:03:46] <JT-Shop> nope
[22:03:56] <Connor> and 1 Dial indicator with mag base.. and another one coming..
[22:03:57] <andypugh> You can touch-off with the caliper.
[22:04:01] <JT-Shop> you should be good to start then
[22:04:27] <Connor> Need that with my CNC Router.
[22:04:35] <ssi> probably would be a good idea to get a small DTI and some kind of holder that you can put in or around the spindle
[22:04:39] <JT-Shop> after you square and size your material just put a dowel pin in your collet to set you X location of the part in your vise
[22:04:42] <ssi> for tramming the mill head to the table and tramming the vise to the table
[22:04:45] <Connor> I wonder if you get better pricing if you call and order vs placing order online ?

[22:05:18] <andypugh> (Yikes)
[22:06:02] <andypugh> They nest into each other (and crush a bit too) so you are less likely to clamp the parallel instead of the work.
[22:06:03] <Connor> tinyurl or bitly.
[22:06:22] <andypugh> http://www.chronos.ltd.uk/acatalog/XC278L.jpg
[22:06:33] <andypugh> (I was copying from the wrong page)
[22:06:43] <JT-Shop> I would end up drilling them lol
[22:07:08] <andypugh> They are more likely to get out of the way than a solid parallel
[22:07:22] <JT-Shop> ssi there doesn't appear to be any need to tram the head on that one
[22:07:43] <JT-Shop> instead of shooting out the side of the vise :)
[22:11:35] <andypugh> Reading that Interweb, it seems that the foam board I have might actually be intended for foundry patterns. One plus of CNC is that trying again is no real pain.
[22:12:06] <JT-Shop> do you want the roughing outside one with 10mm passes?
[22:13:42] <JT-Shop> andypugh: one thing for sure being active on the forum forces you to know EMC very well :)
[22:14:09] <andypugh> If it isn't too much trouble. The roughed part was actually good enough in the MDF (considering how much rework and painting it needs anyway)
[22:14:34] <JT-Shop> no trouoble
[22:14:40] <JT-Shop> trouble
[22:14:49] <andypugh> JT-Shop: Yes, most of the time I don't know the answer myself the first time, but know where to find it.
[22:15:11] <andypugh> Also, no rush. Not going near a CNC machine for 2 weeks. (not going near land for 1 week)
[22:17:53] <JT-Shop> lucky you, I'll do it now so I don't forget

[22:34:57] <JT-Shop> I hate tilting heads like the folks in Maine
[22:35:05] <ssi> also, since my mesa card is running all 3v3 IO, I think I'll need some kind of op amp circuit to get 10v
[22:38:05] <KimK> ssi: What daughter card(s) are you using? (Just curious)
[22:38:09] <ssi> none!
[22:38:10] <ssi> :D
[22:38:12] <andypugh> ssi: Use the +10 from the VFD and an opto-isolator into an RC
[22:38:25] <ssi> hmm, that'd work
[22:38:43] <andypugh> Pretty much what I have.
[22:39:06] <ssi> i dunno if I have any discrete optoisolators
[22:39:16] <ssi> I have optointerruptors, could just wrap tape around it

[22:40:43] <andypugh> I did have a design with two optos, one that conducted on the PWM low cycle and one on the high. That ought to be linear with frequency.
[22:41:28] -!- mhaberler has quit [Quit: mhaberler]
[22:41:50] <andypugh> The issue is that with a resistor to the input and a cap to ground, the current flows in at +V and out at -V. But with an opto it flows in when the opto is on. And stays there.
[22:42:31] <andypugh> So you need to make other arrangments to bleed the charge out of the cap.
[22:42:43] <ssi> I may play with an op amp circuit first
[22:42:56] <ssi> 10v single sided supply from the +10vdc that the vfd provides
[22:43:02] <ssi> 0-3v3 in, 3x gain

[23:15:39] <ssi> without stealing one out of something else? :P

[23:25:17] <Jymmm> or just a resistor and a cap.
[23:25:20] <ehidle> ssi: nothing wrong with doing amp/filter in a single stage
[23:27:05] <ehidle> ssi: just put a cap in parallel with the feedback resistor in your standard non-inverting op-amp topology
[23:27:09] <andypugh> ssi: My filter. Works a treat (it's on one of those Arduino shields): http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?ResolverToQuadratureConverter

[23:27:49] <ssi> k imma go play
[23:28:03] <andypugh> I admit, I have no idea how it works, I got the circuit diagram from Wikipedia.
[23:28:35] <ssi> :D
[23:29:21] <andypugh> (Just the filter, I do understand the rest)
[23:29:27] <ehidle> yeah a Sallen-Key will give you a second order
[23:29:30] <ehidle> for an extra component
[23:29:43] <andypugh> Seems very effective.
[23:29:48] <ehidle> yes they are
[23:29:54] <ssi> I'm looking at the sallen-key stuff n
[23:29:58] <andypugh> Does it still have a phase lag?
[23:30:07] <ehidle> the phase varies with frequency
[23:30:29] <andypugh> Not a problem in this application, of course.
[23:30:37] <ehidle> do you guys have LTSpice?
[23:31:00] <ssi> ehidle: tl072 should be ok single-ended, yes?
[23:31:02] <andypugh> Isn't that cheating>
[23:31:03] <ehidle> (free app at www.linear.com for doing basic circuit modeling... can do bode plots for op-amp filters and all that)
[23:31:19] <ssi> faster for me to breadboard it and scope it than get the damn sim working :)

[23:31:50] <ehidle> ssi: most op-amps will work single-ended as long as you bias them right.. just have to make sure you use the non-inverting topology and always have a positive input signal
[23:32:13] <jdhNC> TI has TINA-TI, another spice-alike that works well
[23:33:08] <ssi> andypugh: what's the PWM frequency for spindle control?
[23:33:19] <ssi> er rather, I know you can set it to whatever
[23:33:22] <ssi> but what's practical
[23:34:14] <andypugh> Considering that the VFD is 50 or 60Hz, a small factor of that seems sensible.
[23:34:17] -!- Bridgeport2 has quit [Quit: ChatZilla [Firefox 4.0/20110318052756]]
[23:34:34] <andypugh> Say 1kHz?
[23:35:10] <ssi> kk
[23:35:25] <andypugh> You don't want to go too high or you lose PWM resolution (much more of a problem with software PWM than FPGA PWM)
[23:35:54] <andypugh> If higher frequencies make the parts cheaper, go higher. But Mhz is too much :-)

[23:49:43] <KimK> andypugh, mhaberler: Thanks for helping John (Bridgeport2) while I was unavailable.
[23:49:45] <KimK> andypugh: I just saw your reply to my post. Maybe we should chat a bit before you disappear? How can I help you by using my loaner 7i49? What can I send you regarding the "BSPI instances" you asked about?
[23:50:12] <mhaberler> sure
[23:50:35] <andypugh> Do you have a firmware for the 7i49?
[23:50:57] <KimK> mhaberler: And thanks too for your work on improving the tool change, we certainly can use that.
[23:51:49] <andypugh> It seems that the patch I posted only currently works on 2.5, unless you seperately patch your master-based branch with http://git.linuxcnc.org/gitweb?p=emc2.git;a=commit;h=9cf47f1b89af9a59fb9a74df2f35e4b636d85b9d
[23:52:25] <JT-Shop> andypugh: have a safe trip... talk to you later
[23:52:31] <mhaberler> it's not there yet.. it turned out a fairly hard problem to solve, but its on the way; as a fallout there will be Python embedded in the interpreter -- meaning oword subs may be Python code
[23:53:03] <andypugh> But, having done that you should find that the BSPI pins get named in the dmesg output, and that there are BSPI instance names declared there too.
[23:53:49] <andypugh> At that point it is a case of taking the sample 7i65 comp file and modifying it a bit.
[23:54:08] <andypugh> It might turn out to be really easy. Or it might not.
[23:54:24] <KimK> andypugh: PCW sent me a bitfile for the 7i49, but I have not yet had time to do anything with it. I'll have to look it up, I think I asked for a sort of typical assortment of cards with the 7i49. BRB...
