[00:01:54] <FloppyDisk5_25> Hmmpfff... The pirate guy is Duc, he's on this irc regularly... You just need to ask at the right time, I guess.
[00:02:26] <FloppyDisk5_25> that same writeup is also here: https://forum.linuxcnc.org/forum/12-milling/29997-bridgeport-boss5-stepper-to-servo?limitstart=0
[00:03:01] <Contract_Pilot> Ok, So i may have to tie it to 24V and use outputs
[00:05:34] <Contract_Pilot> I can set the VFD up for sinking or sourcing
[00:06:24] <FloppyDisk5_25> That pirate guy mentioned how he set it up (sinking/sourcing).
[00:06:57] <Contract_Pilot> Yea, looks like he is using external psu i want to keep wiring to a min and use the 124v internal
[00:14:32] <FloppyDisk5_25> Watch out for noise...
[00:15:28] <FloppyDisk5_25> Keep power isolated from vfd to 7i76 as best you can.
[00:15:56] <FloppyDisk5_25> Umm, 12v internal? that should be ok.
[00:16:20] <Contract_Pilot> the WJ200 requires 24V
[00:16:31] <Contract_Pilot> My Field is 12V
[00:22:22] <Contract_Pilot> So Instead of using these
[00:22:27] <Contract_Pilot> # 5 SPINDLE ENA-
[00:22:27] <Contract_Pilot> # 6 SPINDLE ENA+ Pin 1 (Logic Input)
[00:22:27] <Contract_Pilot> # 7 SPINDLE DIR-
[00:22:27] <Contract_Pilot> # 8 SPINDLE DIR+ Pin 2 (Logic Input)
[00:22:43] <Contract_Pilot> I would tie it to output ?
[00:22:51] <Contract_Pilot> and use 12V Field
[00:23:00] <Contract_Pilot> ahhh 24V
[00:31:33] <Contract_Pilot> BBL
[02:21:35] <Contract_Pilot> Spindle is working yep yep..
[02:21:45] <Contract_Pilot> Next
[02:26:55] <Deejay> moin
[02:39:47] <Contract_Pilot> Morn
[04:40:01] <XXCoder> heys
[06:09:04] <jthornton> morning
[06:55:08] <Tom_itx> quiet morning
[07:10:01] <jthornton> elderberries should be fat and juicy this year
[07:12:05] <jthornton> wow another order that makes 3 this month
[07:25:27] <archivist> I have a clock to look at at last!
[07:27:01] <jthornton> cool
[07:27:20] <jthornton> a very old one?
[07:30:20] <archivist> a vienna has a case falling apart needing gluing and a polish + hide some blemishes, movement seems not too bad, oiled it and it is ticking
[07:30:46] <archivist> 1880-1930s ish
[07:31:31] <jthornton> wow that is old
[07:31:49] <jthornton> got a photo of it?
[07:32:51] <archivist> not taken any pics yet, I should so there are before/after images
[07:33:56] <archivist> just testing the movement to see how well it goes before I decide restore or clean or a cheap oil and run
[07:35:44] <archivist> there are two bits missing, the hammer off the strike (waiting for brass wire) and the handle off the key (made that already)
[07:57:35] <Contract_Pilot> Evening
[07:57:57] <Contract_Pilot> or Morning hahaha almost bed time... got spindle and encoder working on Path Pilot
[07:59:02] <Contract_Pilot> Waiting on some NC Proximity and NC switches, Few Connectors for Wiring, Molex Pins for the Encoder... And should be able to button her up.
[07:59:36] <Contract_Pilot> Then on to hardware.... Need a coupler for X axis ball nut.
[07:59:43] <Contract_Pilot> Should be able to make it.
[08:00:18] <Contract_Pilot> Tool Post Mount Got the block of metal just need to mill it out
[08:52:14] <MacGalempsy> good morning
[11:33:48] <The_Machine> interesting that #emc redirects here
[11:35:54] <CaptHindsight> The_Machine: this project used to be called EMC = Enhanced machine Controller
[11:44:04] <CaptHindsight> heh Cannot join #emc (Channel is invite only)
[11:44:29] <CaptHindsight> so people end up here when they check for an open room
[11:49:13] <The_Machine> i wonder why it's invite
[11:49:14] <The_Machine> anyway, thanks
[12:43:26] <CaptHindsight> The_Machine: probably to insure that there's little to no free support
[12:44:26] <CaptHindsight> just a guess, my opinions are entirely my own and don't reflect the opinions of the developers and management of EMC
[12:44:46] <archivist> I think it is a state "we" left it
[12:45:20] <archivist> the BORG called EMC had no choice there :)
[13:21:52] <plpower> hi
[13:23:22] <plpower> CaptHindsight: emc is a factory and a inshurenc company priivate chat
[13:24:09] <plpower> CaptHindsight: no chance for a convert try o the max file
[13:24:27] <plpower> got time to run hours of fine milling
[13:24:42] <CaptHindsight> I'm tied up until the weekend
[13:25:02] <plpower> ok so maybe next week i will ask again
[13:25:15] <plpower> cand find a autodesk chatroom
[13:25:23] <plpower> or fusion360
[13:26:18] <CaptHindsight> the file opens as a wireframe, then you can change it to render in different modes
[13:27:00] <CaptHindsight> if you have to jump through hoops to export it then it's a first for me
[13:32:23] <plpower> theee is a video from 3dsmax to fusion30 on youtube that klicks you thrue the system
[13:33:37] <CaptHindsight> yes, I saw the link
[13:33:37] <plpower> next week time enoph
[13:37:51] <plpower> ok Asia Food today wife calling for Dinner im off
[13:38:06] <plpower> have a Cool Milling and dont break to many Bits
[16:22:59] <Deejay> gn8
[16:54:28] <Frank_15> T_T cant find any webpage shipping precision ground METRIC flat stock, maybe anyone knows one??
[16:57:36] <CaptHindsight> https://store.diesupplies.com/precision-marshall-ground-flat-stock-c13.aspx
[16:58:36] <CaptHindsight> http://products.southerntoolsteel.com/viewitems/flat-ground-stock/flat-ground-stock-metric-sized?
[17:02:38] <Frank_15> thanks! i've already seen the first page, but they were only shipping in 1m lenght, which is too much to ask someone to put inside a travel bag.. he
[17:03:08] <Frank_15> i will check the dimensions they ship on sotherntoolsteel, thanks capthindsight,
[17:07:11] <Frank_15> do you know if at southern they send 1 piece, or they only ship in large quantities
[17:08:17] <Frank_15> lol, already answered myself
[19:28:13] <Duc_main> anyone have experience with step up boasters. Looking for 12v to 48-72v
[19:31:12] <Tom_itx> http://www.ebay.com/itm/DC-Boost-Voltage-Regulator-Car-Motor-12V-24V-to-48V-60V-72V-Power-Supply-Charger-/281538416723?hash=item418cff5053:g:rSgAAOSwiCRUmLFs
[19:31:16] <Tom_itx> how much current?
[19:31:34] <Duc_main> Need to run Nema34 motor off the thing
[19:31:48] <Tom_itx> likely not a good idea to use a boost
[19:32:21] <Tom_itx> getting the current you need could a trick
[19:32:42] <Duc_main> wonder what else I could use. Figure I have a 12V power from the truck or do I use a AC converter then drop to DC
[19:33:09] <Tom_itx> is this a truck application?
[19:33:20] <malcom2073> You should use a better suited motor I'd say
[19:33:28] <Duc_main> yes and no you could say
[19:33:50] <Tom_itx> trying to find the application before recomending anything...
[19:33:57] <Duc_main> for the turrent application. Figure I can use a 12v car battery or jumper cables off the truck
[19:34:26] <Tom_itx> get an AC to dc supply
[19:34:51] <Duc_main> for a much cleaner power supply
[19:34:57] <Tom_itx> that one i posted handles 5A i think if that's enough
[19:35:19] <Tom_itx> keep in mind those are Chinese amps
[19:36:01] <Valen> why are you stepping voltage up that far?
[19:36:07] <Valen> what is the total power requirement?
[19:36:40] <Tom_itx> yeah, you don't need extreme speed on a turret changer
[19:37:07] <Duc_main> not really Could probably run them off 12V
[19:40:01] <Duc_main> its not a high speed app
[20:15:04] <CaptHindsight> I like the name on the back of the supply "Fultree" it sounds like a western name but it's not
[20:15:44] <CaptHindsight> man you can't climb up here since it's a Fultree
[20:17:10] <malcom2073> heh
[20:22:36] <codepython777> anyone into laser cutting hanging in here?
[20:34:19] <CaptHindsight> laser cuttin, metlin and curin
[20:43:08] <codepython7771> http://www.shopbottools.com/mProducts/desktop.htm - does anyone own one of these?
[21:12:41] <witnit> holy moly
[21:12:47] <witnit> why is it sooo expensive?
[21:15:14] <witnit> "precision-coated lead screw with anti-backlash" yeehaw
[21:17:35] <malcom2073> Lol because shopbot
[21:17:44] <malcom2073> it's for people who don't really know what they're doing, but have money to burn
[21:17:55] <malcom2073> But not enough money to buy a *real* machine
[21:19:47] <witnit> I just cant fathom how it even I just dont...this...my brain.... COST does NOT equal VALUE
[21:21:30] <witnit> for that much money I could buy machines weighing WELL over 2 tons
[21:21:44] <witnit> 2 tons of IRON
[21:22:30] <witnit> for that much money I could rent a building to put 40 tons of machinery in for a year
[21:23:16] <gregcnc> would get you a few months rent around here
[21:26:29] <witnit> heh, my building rent is <6k per year and I still havent filled it up, that would include 10 screw machines with barloaders, 4 lathes, a mill and room for inventory, robotic welder cell, chip spinner, chip tubs, fork truck, you name it
[21:29:16] <gregcnc> they sell those machines because there are customers
[21:32:59] <SpeedEvil> To be fair - if you can make a decent machine tool in 100lb - it could be at a signfiicant premium
[21:33:25] <SpeedEvil> Regrettably, that does not look 'decent'
[21:33:29] <witnit> ^
[21:36:15] <witnit> I feel only slightly bad that the guy was asking about it and me saying all that stuff, seriously though, I feel like giving it any credit at all should be punishable by law. and anyone even looking at it should get an earful about value vs cost
[21:50:05] <enleth> witnit: maybe there's just an obscure market for rich people who need to mill butter, soap and wax
[21:50:34] <enleth> I don't see any other explanation for such a machine
[21:59:35] <enleth> which reminds me that I need to buy some hard soap for the bridgeport training I'm doing this saturday
[22:14:36] <yasnak> witnit, what screw machines?
[22:15:37] <SpeedEvil> yasnak: http://www.shopbottools.com/mProducts/desktop.htm
[22:15:37] <yasnak> i've got stars citizen and now index
[22:16:01] <yasnak> 5 grand?
[22:16:28] <yasnak> unless it comes with a free seat of powermill i'm out
