[00:01:30] <Tom_itx> well you can't buy one at ikea
[00:03:32] <andypugh> The problem is that the lathe is going to look rather scruffy when I fit it :-)
[00:03:48] <Tom_itx> guess you know what to do about that
[00:04:07] <andypugh> Need to learn how to do frosting :-)
[00:04:29] <Tom_itx> and what is that?
[00:04:36] <Tom_itx> learning all sorts of new terms here

[00:16:13] <atom1> PCW, what board do you add to the firmware.txt for the 5i20... i20_400 ?
[00:16:30] <atom1> for the 9.2 webpack stuff...
[00:16:48] <PCW> firmware.txt?
[00:17:15] <atom1> the build_bit.sh reads that file
[00:17:23] <atom1> and builds those bit files listed
[00:17:37] <atom1> i43_400 SVST2_4_7I47
[00:17:43] <atom1> that's what i had for mine
[00:18:03] <PCW> dont know
[00:18:22] <atom1> how do you build them with 9.2?
[00:18:27] -!- printallthething has quit [Read error: Operation timed out]
[00:18:39] <andypugh> I think that the LinuxCNC Hostmot2 build environment differs from the Mesa one
[00:19:18] <PCW> it thats just including the card stuff the file included is i20card.vhd
[00:20:37] <micges> atom1: -i20 SV12 SVST2_4_7I47 SVST2_8 SVST8_4 SVST8_4IM2 SVST8_3P SV12IM_2X7I48_72 SV12_2X7I48_72 TPEN6_6 SVTP6_7I39
[00:21:06] <atom1> that will build several
[00:21:08] <micges> atom1: just delete bit files you don't need
[00:21:13] <atom1> yeah
[00:21:38] <atom1> you don't need to specify the 200 400 gate part?
[00:21:50] <andypugh> Yes, you very much do need that
[00:22:09] <andypugh> (For cards where it is ambiguous)
[00:22:11] <micges> atom1: nope with 5i20
[00:22:22] <atom1> k
[00:22:29] <atom1> i knew you did with mine
[00:22:36] <atom1> 7i43
[00:23:13] <atom1> it's just been a long time since i've built one with 9.2
[00:24:58] <micges> I have env ready, it can be hard time to setup any webpack to compile mesa stuff
[00:25:20] <atom1> http://tom-itx.dyndns.org:81/~webpage/emc/xilinx/xilinx_install_index.php
[00:25:27] <atom1> i wrote that when i did it the first time
[00:27:00] <PCW> 5i20 only comes in one FPGA size
[00:27:35] <micges> seems usefull, worth to put on wiki, many have problems with webpacks
[00:27:49] <atom1> there's also one for 14

[01:05:53] <Tom_itx> PCW do you optimize for speed in 9.2 as well?
[01:07:07] <PCW> Yes (mostly) some things are close to the limit and need to be optimized for area
[01:07:45] <Tom_itx> ok
[01:08:03] <Tom_itx> seem to have both environments back working again

[02:36:54] <PCW> only the Spartan2 boards (5I20,4I65)
[02:37:18] <Tom_itx> what about 7i43?
[02:37:51] <Tom_itx> i thought i used 9.2 once for it but maybe not

[03:31:20] <lwizardl> I was wondering if taking an old inkjet printer apart if I could reuse the hardware to move a webcam or base for a 3d scanner
[03:32:27] <eric_unterhausen> depends on the printer
[03:32:35] <eric_unterhausen> generally, the older, the better the parts
[03:33:17] -!- sumpfralle has quit [Ping timeout: 252 seconds]
[03:33:32] <eric_unterhausen> if you can find an old plotter, those were good
[03:34:47] <lwizardl> well I have a HP Laserjet 4, a few old HP inkjets, a epson AIO
[03:34:55] <lwizardl> and a few brothers
[03:35:27] <lwizardl> I have 2 old plotter/printers but those I want to repair

[03:37:44] <lwizardl> hmm this is one of the printers I have http://breakingyard.blogspot.com/2008/07/lexmark-z1300-printer.html
[03:38:14] -!- eric_unterhausen has quit [Ping timeout: 252 seconds]
[03:38:54] <CaptHindsight> those are pretty small printers
[03:39:42] <cradek> the original hp deskjets had a nice dc motor with encoder, and a belt to move the head
[03:39:48] <lwizardl> yeah it was free and it works just the ink usage is terrible
[03:40:24] <cradek> they are very hard to disassemble until you know the trick: hold it as far over your head as possible, and accelerate downward quickly
[03:40:50] <CaptHindsight> aqueous ink is ~$5/L
[03:41:00] <lwizardl> like maybe 75-100 sheets before its time to replace on it. since I use a epson for my color prints and a lexmark laser for text only I dont need the others
[03:44:00] <CaptHindsight> http://refillbay.com/product/1-gallon-bulk-ink-for-epson-printer-cartridges-yellow.php?ref=ADWPR&gclid=CNHm8K-lhLwCFQISMwod0woAVA you can even buy bulk gallons for ~$70
[03:44:42] <lwizardl> nice
[03:45:10] <lwizardl> I will have to see if that ink will working in my inkjet. I have an epson r320 for my main color prints
[03:45:37] <CaptHindsight> the trick with Epson is resetting the cartridge
[03:46:44] <CaptHindsight> 6 colors (CcMmYK)
[03:47:01] <CaptHindsight> you also need to filter to <10um
[03:47:23] <lwizardl> I have the aftermarket carts in mine.
[03:47:50] <lwizardl> I plan to buy the refill tube versions. i found them on ebay for about $30
[03:48:08] <lwizardl> so then I can just keep refilling the bottle that is attached
[03:49:01] <CaptHindsight> bulk ink kits, yes they just modify the cartridges with tubing and have a reset feature
[03:50:32] <Tom_itx> ok i updated the xilinx 9.2 page a bit
[03:50:39] <CaptHindsight> just be sure to filter\
[03:50:40] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/emc/xilinx/xilinx92_install_index.php
[03:52:48] <lwizardl> these look similar to thes I bought. http://www.ebay.com/itm/12-Pack-T048-Non-OEM-Ink-For-Epson-Stylus-Photo-R200-R220-R300-R300M-R320-/121065262723?pt=US_Ink_Cartridges&hash=item1c300d4e83
[03:53:14] <lwizardl> I only paid $7 for a full set of ink on mine and have printed lots of dvd covers so far
[03:53:37] <lwizardl> and this is the CIS upgrade I plan to buy http://www.ebay.com/itm/Continuous-ink-system-for-Epson-R200-R220-R300-R320-/400153994845?pt=US_Ink_Cartridges&hash=item5d2b09665d

[04:36:47] <tjtr33> andypugh, the finish on the Rivett is beautiful, not the scraped flaking i'm familiar with (twist the scraper), more like flaking (straight pushes, alternating rows of 90 degrees).
[04:36:53] <tjtr33> what you have is really pretty tho, like chemical crystaline patterns.
[04:36:53] <tjtr33> dont go deeper than your wipers can handle!

[15:16:26] <CaptHindsight> what's the difference between the -ta and the com?
[15:16:35] -!- jnaour has quit [Read error: Connection reset by peer]
[15:16:43] <CaptHindsight> besides the connectors?
[15:17:04] <heathmanc> the ta and the com have pluggable terminals
[15:18:30] <heathmanc> but the com has common input reference and a common output power source
[15:23:00] <CaptHindsight> the 7i37com has optos on the inputs, can you use 4-24V to supply the touchprobe through a suitable resistor and monitor the probe?
[15:23:19] -!- jnaour has quit [Read error: Connection reset by peer]
[15:23:48] <heathmanc> not sure
[15:24:02] <heathmanc> it's just a touch place, not a real probe
[15:24:16] <CaptHindsight> connect an input to the probe side of the resistor, when the probe goes to ground the voltage will drop to 0
[15:25:02] <CaptHindsight> a probe is usually just insulated conductor from the machine
[15:25:15] <heathmanc> right, and this is insulated
[15:25:17] <CaptHindsight> whats your "touch place"?
[15:25:32] <heathmanc> just copper pcb single sided
[15:25:47] -!- jnaour has quit [Read error: Connection reset by peer]
[15:26:33] <CaptHindsight> so you have a probe insulated from the machine? and you gave a conductive surface (the copper pcb)?
[15:26:42] <CaptHindsight> gave/have
[15:26:47] <heathmanc> yes
[15:27:06] <heathmanc> just clamp an alligator clip on the bit
[15:27:16] <heathmanc> i had it working with the 7i37ta
[15:27:29] <heathmanc> but i am trying to eliminate some wiring
[15:27:40] <CaptHindsight> so you're touch probe complete the circuit when it touches the copper trace/foil side
[15:27:48] <CaptHindsight> you're/your
[15:27:52] <heathmanc> yes
[15:27:58] <CaptHindsight> sorry no coffee yet
[15:29:32] <CaptHindsight> you can wire the pcb to ground and then use a pull up resistor from power (4-24V) to the probe
[15:30:14] <CaptHindsight> then run the probe side of the resistor to an input, when the input is low the probe has made contact with the pcb, when high it has not
[15:30:32] <heathmanc> or the other way around wouldn't it be
[15:30:44] <heathmanc> the "probe" is the tool bit
[15:30:58] <CaptHindsight> no, since the input is on the probe side of the resistor
[15:31:30] <CaptHindsight> the probe should be insulted from the machine
[15:31:42] <heathmanc> the pcb is
[15:31:49] <CaptHindsight> or the probes tip to be more exact
[15:32:05] <heathmanc> there lies the problem..
[15:32:29] <CaptHindsight> but you can connect a wire to the copper side of the pcb
[15:32:39] <heathmanc> yes
[15:32:46] <CaptHindsight> so ground it
[15:33:12] <CaptHindsight> if your probe is not insulted from the machine you can do this the other way around
[15:33:28] <heathmanc> right, it has to be the other way around
[15:33:41] <CaptHindsight> power (4-24V) through a resistor to the pcb foil
[15:33:59] <CaptHindsight> pcb foil to an input of the 7i37
[15:35:39] <CaptHindsight> the foil will be current limited by the resistor and be high (4-24V) until the probe (ground) touches it

[16:08:54] <R2E4_> The green light is flashing.
[16:09:11] <jthornton> just use a 7i77 or 7i76 for the second card in pncconf I think
[16:09:22] <jthornton> and only configure the I/O

[16:13:25] <R2E4_> I did, and no pins, let mecheck again.
[16:15:10] <jthornton> did you pick 7i76x2?
[16:15:46] <R2E4_> no
[16:16:10] <jthornton> the second card won't show up unless you pick x2
[16:16:35] <R2E4_> The pins are there, there hidden under hm2_5i25.0.7i84.... lol
[16:17:35] <R2E4_> The green light is flashing so it did see it automagically. Guess its in the firmware, no need to program it.
[16:18:12] <R2E4_> The pins just automagically showed up.... Thats fantastic!!!!
[16:18:29] <jthornton> a 5i25 has the firmware built in
[16:18:46] <jthornton> you do not need anything to configure that
[16:20:41] <pcw_home> the driver probes the remote card for its name and I/O capabilities so it is pretty automatic
[16:21:08] <skunkworks> automagical
[16:22:59] <R2E4_> To add anothr 7i84 card just connect TB6 parralell rs422 and it will find it and give it hm2_5i25.0.7i84.1?
[16:23:36] <pcw_home> You need another RS422 channel
[16:23:50] <pcw_home> (a 7I74 will give you 8 more)
[16:24:01] <pcw_home> (for example)

[16:31:15] <R2E4_> IS there a reason why you went with RS422 instead of rs485? RS485 you can put 32 addresses on one line and give each module an address.
[16:31:41] <R2E4_> speed?

[16:34:01] <pcw_home> radial RS-422 is scalable and I hate daisy chain wiring

[17:16:17] <CaptHindsight> every part I've ever checked to swap was off by too much to work
[17:16:36] <zeeshan|2> thats exactly what im worried about
[17:16:42] <zeeshan|2> i know the Yoke or whatever you call it
[17:16:46] <zeeshan|2> where the nuts go in
[17:16:51] <zeeshan|2> is different
[17:16:56] -!- garfong has quit [Quit: Leaving]
[17:17:11] <zeeshan|2> im hoping somebody has already ordered some ball screws for this mill and they'll have dimensions =D
[17:18:39] <jdh> got your lathe X done?
[17:18:52] <zeeshan|2> jdh: no
[17:19:00] <zeeshan|2> im still making the 3 hp motor mounts for it
[17:19:36] <CaptHindsight> I'd like to find a press brake like this http://www.ebay.com/itm/261354336799
[17:20:01] <zeeshan|2> and waiting on vfd
[17:20:05] <zeeshan|2> i do shit in stages so i can use the machine if a job comes on the side
[17:20:06] <zeeshan|2> :)
[17:20:06] <zeeshan|2> the other day i had to make a spacer
[17:20:07] <zeeshan|2> so i just bolted up the 4 bolts for the carriage and just used the rack and pinion to move the Z
[17:20:07] <zeeshan|2> :)
[17:20:47] <jdh> you just did.
[17:21:33] <CaptHindsight> heh, only closer http://www.ebay.com/itm/VERSON-25-TON-PRESS-BRAKE-/221330039274 like this, but still for sale
[17:21:33] <zeeshan|2> lol
[17:21:40] <zeeshan|2> i wish i had a shop space like you guys
[17:21:47] <zeeshan|2> i have to make use of my 20x20 garage =[
[17:22:13] <CaptHindsight> mine is dirt cheap 6K sq ft
[17:22:50] <CaptHindsight> excess warehouse build-outs from before the crash of '08
[17:22:56] <zeeshan|2> hehe
[17:23:00] <zeeshan|2> did you buy the place
[17:23:04] <zeeshan|2> or rent it out
[17:23:24] <CaptHindsight> rent for a few year before i go
[17:25:50] <zeeshan|2> my dad's got this empty land that he's doing nothing with
[17:25:55] <zeeshan|2> i was thinking of putting up a metal building there
[17:26:11] <zeeshan|2> the only problem is its 50 minutes from my house
[17:26:14] <CaptHindsight> concrete pad one weekend
[17:26:18] <zeeshan|2> and that's a hell of a drive to go work on stuff :)
[17:26:40] <CaptHindsight> thats like 4 miles during rush our
[17:26:46] <zeeshan|2> haha
[17:26:49] <CaptHindsight> our/hour
[17:26:51] <zeeshan|2> its about 50 miles
[17:27:38] <zeeshan|2> we'll see. right now all the major machines are in the garage and they fit fine :P
[17:28:05] <CaptHindsight> I'm running out of power here 208/200A 3p
[17:28:45] <CaptHindsight> wish they had run 480 instead
[17:28:51] <zeeshan|2> they actually deliver 208 3ph?
[17:28:57] <zeeshan|2> i thought it was only 480
[17:29:00] <zeeshan|2> or 600V
[17:29:10] <CaptHindsight> yeah, pretty common now
[17:29:25] <zeeshan|2> pretty much all my stuff had a vfd
[17:29:33] <zeeshan|2> 230v 1ph to 3ph
[17:29:34] <zeeshan|2> :)
[17:29:34] <CaptHindsight> I think they figured warehouse vs industrial
[17:29:47] <zeeshan|2> even 208 means most of your industrial machines need a motor change
[17:30:00] <zeeshan|2> cause they're usually 480v or 575V
[17:30:18] <CaptHindsight> and no AC in the warehouse, only in the 4K sq ft offices
[17:31:11] <CaptHindsight> it's only bad on 90F + days and want to concentrate
[17:31:35] <zeeshan|2> you sir
[17:31:38] <zeeshan|2> need 1hp fans
[17:31:44] <zeeshan|2> =D
[17:31:56] <CaptHindsight> i just run hot, I have them
[17:32:21] <CaptHindsight> fans + dehumidifiers

[17:32:33] <zeeshan|2> use one of those
[17:32:35] <zeeshan|2> air conditioned suits
[17:32:36] <zeeshan|2> :-)
[17:32:45] <CaptHindsight> 5 ton AC unit maybe next
[17:32:47] <zeeshan|2> its anti-radiation too!
[17:33:18] <CaptHindsight> I started making one last year
[17:33:47] <CaptHindsight> ends up packing those chill bags into a vest work well
[17:33:56] <CaptHindsight> just change them every 2 hours
[17:34:40] <CaptHindsight> http://www.glaciertek.com/default.aspx?AspxAutoDetectCookieSupport=1 like these
[17:34:42] <zeeshan|2> http://thekevinchen.wordpress.com/2012/03/11/mclarens-air-conditioned-race-suits/
[17:34:43] <zeeshan|2> wow
[17:34:45] <zeeshan|2> mclaren made some
[17:35:02] <zeeshan|2> oh nice!
[17:36:02] <zeeshan|2> ah so it jut uses a special material thats stays cold
[17:36:10] <zeeshan|2> i thought it was using something like peltiers
[17:36:18] <CaptHindsight> what they use in gel packs for colling
[17:36:22] <CaptHindsight> cooling
[17:36:45] <CaptHindsight> somebody here made a fur suit with peltiers
[17:36:53] <zeeshan|2> http://www.fastcodesign.com/1662859/nanotech-clothing-warms-in-winter-cools-in-summer
[17:36:58] <zeeshan|2> this guy already built one using peltiers
[17:38:21] <CaptHindsight> you never know around here, one summer it barely gets into the 80's the next it's 90's half the time
[17:38:41] <zeeshan|2> yea its pretty mild up here in ontario
[17:38:48] <zeeshan|2> just winters can get brutal
[17:39:03] <CaptHindsight> this winter is nuts
[17:39:11] <zeeshan|2> my coolant 50/50 mix
[17:39:14] <zeeshan|2> actually froze up!
[17:39:18] <CaptHindsight> back to -10C today, was +10 2 days ago
[17:39:19] <zeeshan|2> during that polar vertex event
[17:39:37] <zeeshan|2> its mighta been more like 45/55
[17:39:48] <zeeshan|2> had chunks of ice in it
[17:39:59] <CaptHindsight> yeah I even went back to 5w in the vehicles
[17:40:55] <CaptHindsight> zeeshan|2: I finds lots of used cnc's in the MI, Oh area
[17:41:19] <CaptHindsight> but I bet they would charge customs on the border crossing
[17:43:19] <R2E4_> They allways ask way more for machines up here in Canada. Sometimnes you can find good deals.
[17:43:52] <CaptHindsight> the shop in China is +10 C in winter and up to 42C in summer
[17:43:54] <skunkworks> like an r2e4?
[17:44:13] <CaptHindsight> have to get the space suits or AC there
[17:44:19] <R2E4_> yes but oyu only pay customson what you paid for iut. If you could get a receipt for 500, you would only pay like 50.00 or so.
[17:45:03] <R2E4_> Well, I got my R2E4 for cheap, I actually cut a job on my cnc router for it.
[17:45:33] <CaptHindsight> I'd buy a peltier suit if the coolers are replaceable
[17:45:43] <R2E4_> I just converted it to 220 single phase, put a VFD on it and everything worked.
[17:46:03] <CaptHindsight> losing a few pounds would also help :/
[17:51:22] <CaptHindsight> http://www.ebay.com/itm/140810782163 were these accurate enough to use the twin spindles to make one part seamlessly?
[17:53:01] <CaptHindsight> probably accurate enough but did the travel overlap each spindle to extend the X?
[17:55:53] <CaptHindsight> I was going to drive from Detroit to London, ON to install equipment and they were going to charge customs for the tools even though they were coming back with me

[19:36:58] <pcw_home> yes you can use the signal machine-is-on

[21:13:51] <heathmanc> have a 1.34hp spindle that I'm unsure of the pinout.. Can't seem to get a manual
[21:14:17] <heathmanc> has a 6 pin latching connector
[21:14:21] <andypugh> How many wires?
[21:14:41] <andypugh> All the same size?
[21:14:49] <heathmanc> can't tell, just 6 pins on the connector.
[21:14:52] <heathmanc> wires are internal
[21:15:58] <andypugh> Is it just a motor?
[21:16:21] <heathmanc> appears to be 5 wires and a ground
[21:16:32] <heathmanc> it's a 24k rpm ekstrom carlson spindle, square
[21:17:01] <andypugh> How do the wires ring out with a multimeter?
[21:17:33] <heathmanc> working on it now
[21:19:24] <heathmanc> showing 2 ohm between 1-2-3
[21:19:45] <heathmanc> .4 between 4-5
[21:19:45] <andypugh> Those sound like the 3-phase motor wires then.
[21:19:50] <heathmanc> it is 3 phase
[21:19:56] <heathmanc> just not sure why the 5 wires
[21:20:00] <andypugh> I am going to guess that 4-5 are a thermistor
[21:20:07] <heathmanc> i can understand 3 and the ground
[21:20:13] <heathmanc> possibly
[21:20:25] <heathmanc> getting ready to wire it up to a hitachi wj200
[21:20:28] <andypugh> Put it in the freezer and see if 4-5 changes?
[21:20:50] <andypugh> (or the oven)
[21:20:57] <ries> http://imgur.com/gallery/GRbigda

[22:07:09] <andypugh> They can probably be hex-crimped, but soldering is probably your only option.
[22:07:29] <heathmanc> lol, the connector has a tab to release them
[22:07:34] <heathmanc> i will solder them

[22:22:26] <andypugh> You need a fairly powerful iron. I tend to push the iron into the cup, fill it with some solder, then hold the tinned wire against the iron and when all the slodder on both is molten pull the iron out, push the hot wire into the cup of solder, then wince in pain as the heat travels up the wire to my fingers.
[22:22:55] <heathmanc> sounds about normal
[22:23:08] <GuShH_> use pliers you dumb simpleton
[22:23:16] <heathmanc> i have a 150 watt gun

[22:25:38] <heathmanc> hope to get it to flow

[23:47:56] <Loetmichel> and not really precise
[23:47:57] <zeeshan|2> 49"
[23:48:09] <zeeshan|2> that's good enough to measure lead screw error

[23:54:22] <zeeshan|2> haha
[23:54:22] <zeeshan|2> wtf
[23:54:32] <zeeshan|2> are you a mechanical engineer?
[23:54:47] <andypugh> When it didn't send parts flying across the room it gave good data. But that was one hell of a scary mouse click to engage the cluth.
[23:56:16] <andypugh> zeeshan|2: Yes, I am a mechanical engineer, and at the time I was a Postdoctoral Research Mechanical Engineer, paid to push boundaries. (the application was component crash-testing to simulate vehicle crash tests)
[23:56:32] <zeeshan|2> that's cool
[23:56:45] <zeeshan|2> im doing my research in metal forming right now
[23:56:53] <zeeshan|2> but your project sounds more fun :)
[23:57:06] <andypugh> Google "cam plastometer"
[23:57:34] <andypugh> And "explosive metal forming"
[23:57:44] <zeeshan|2> i know about the later
[23:57:52] <zeeshan|2> latter, but not the cam plastometer stuff
[23:57:55] <zeeshan|2> never seen that before
[23:58:11] <zeeshan|2> sounds like i'd need a 1/2" plate in between me and the jig
[23:59:06] <andypugh> It's the middle-ground between conventional quasi-static testing and the Split Hopkinson Bar stuff.
[23:59:09] -!- terabyte- has quit [Quit: terabyte-]
[23:59:40] <andypugh> (and the far end of that is the dynamite + split hopkinson bar)
