[00:17:01] <zeeshan|2> can someone help me decode this diagram

[00:30:58] <ssi> zeeshan|2: looks like your pumpenmotor's connected to your umgeschaltet
[00:31:04] <zeeshan|2> ROFL
[00:32:14] <zeeshan|2> i cant tell whats going on
[00:32:17] <zeeshan|2> whats the big X (SL1)
[00:32:22] <zeeshan|2> and ws and dk
[00:32:30] <ssi> SL1 looks like a railroad crossing
[00:32:36] <zeeshan|2> ds looks like a pressure switch
[00:32:42] -!- zlog [zlog!~zlog@ip68-102-196-57.ks.ok.cox.net] has joined #linuxcnc
[00:32:55] <zeeshan|2> its the wire coming from the tank
[00:32:58] <zeeshan|2> yellow covering
[00:33:51] <pcw_home> level float?
[00:34:14] -!- micges-dev1 has quit [Quit: Wychodzi]
[00:35:28] <zeeshan|2> whats the thing with what it looks like is 2 diodes
[00:35:30] <zeeshan|2> 1 2 3 4
[00:35:53] <zeeshan|2> i thought this central lubrication had just power wires
[00:35:58] <zeeshan|2> but it looks like theres 6 wires coming out of the unit
[00:36:00] <zeeshan|2> no idea where they go :P
[00:36:55] <zeeshan|2> nm
[00:36:59] <zeeshan|2> that this is the"pumpenmotor"
[00:37:00] <zeeshan|2> :P
[00:37:09] <ssi> DAS PUMPENMOTOR
[00:37:13] <pcw_home> thats the pumpenmotor (it has two windings so can be 110V or 220V)
[00:37:15] <zeeshan|2> DAS IS
[00:37:31] <zeeshan|2> okay then the float makes sense
[00:37:41] <zeeshan|2> cause it shuts power off the pump if fluid level is low
[00:37:45] <zeeshan|2> so i guess you dont burn out the motor
[00:37:53] <zeeshan|2> actually
[00:37:55] <zeeshan|2> it could also be a light
[00:38:11] <CaptHindsight> re
[00:38:16] <syyl_> sl1 is a lamp
[00:38:32] <syyl_> "pumpenmotor" is a motor
[00:38:35] <zeeshan|2> das lamp
[00:38:43] <zeeshan|2> is dk and ws
[00:38:47] <zeeshan|2> some sort of timed siwtched
[00:38:50] <zeeshan|2> they have funny arrows on em
[00:39:37] <pcw_home> so lamp is on when pump is running
[00:39:43] <CaptHindsight> zeeshan|2: that gif is with German robots and Japanese swords
[00:39:43] <zeeshan|2> yes
[00:39:50] <zeeshan|2> CaptHindsight: haha
[00:40:01] <zeeshan|2> i looked through my pi&d handbook
[00:40:07] <zeeshan|2> and i couldnt match any of those symbols theyre using
[00:40:11] <zeeshan|2> except the ds
[00:40:16] <zeeshan|2> it looks very similar to a pressure switch
[00:40:28] <CaptHindsight> I dob't think that a Japanese robot vendor would have allowed that :)
[00:41:12] <zeeshan|2> if you think about it
[00:41:13] <pcw_home> Yeah DS could be a pressure switch also
[00:41:20] <zeeshan|2> this machine was made in the era where the berlin wall was still up
[00:41:30] <zeeshan|2> :D
[00:43:36] <pcw_home> which wires went to the controller?
[00:43:59] <zeeshan|2> pcw_home: all i know is thers are 6 wires
[00:44:01] <zeeshan|2> 1 of them is ground
[00:44:05] <zeeshan|2> 2 of them are l1 and l2
[00:44:08] <zeeshan|2> the other 3 are a mystery
[00:44:46] <pcw_home> what pins do the 3 mystery wires go to?
[00:44:56] <zeeshan|2> its really hard to tell
[00:44:58] <zeeshan|2> cause the wiring is am ess in there
[00:45:02] <zeeshan|2> im gonna check
[00:45:14] <syyl_> die lampei would guess that at least one goes to the plc
[00:45:22] <syyl_> -die lampei
[00:45:54] <pcw_home> and which pins are L1 and L2
[00:46:23] <pcw_home> 5 looks like one of L1,L2
[00:46:59] <syyl_> 5 and 8?
[00:47:16] <syyl_> maybe
[00:47:36] <syyl_> happy guessing, i go for my bed ;)
[00:48:08] -!- gonzo_nb has quit [Remote host closed the connection]
[00:48:16] <pcw_home> not 8 I dont think (motor would be on all the time)
[00:50:06] <pcw_home> also 1,2,3 seem to be be low voltage (UMAX=42V)
[00:52:22] -!- rob_h has quit [Ping timeout: 240 seconds]
[00:52:52] <pcw_home> so my guess is 4,5 = L1,L2
[00:52:54] <pcw_home> 2= sensor switch common
[00:52:55] <pcw_home> 1,3 sensor switch outputs
[00:55:56] <zeeshan|2> dk is a manual switch
[00:55:57] <zeeshan|2> i found it
[00:56:28] <zeeshan|2> okay the wires that went to the external control cabinet are at pin 1, 2, 4, 5, 8, and ground
[00:56:57] <zeeshan|2> and 8 is one leg
[00:57:08] <zeeshan|2> 5 is the other leg
[00:57:35] -!- lucashodge has quit [Client Quit]
[00:57:57] <zeeshan|2> so the mystery wires are 1 2 4
[00:58:38] -!- jerryitt has quit [Quit: Connection closed for inactivity]
[00:59:13] <zeeshan|2> i think im wrong about pin 5

[01:02:41] <PetefromTn_> Evening folks.
[01:05:12] <ssi> PetefromTn_: hey
[01:05:14] <ssi> any opinion on this?
[01:05:15] <ssi> http://atlanta.craigslist.org/atl/tls/4735122273.html
[01:06:46] <PetefromTn_> Looks like a big heavy bastard huh
[01:06:48] <zeeshan|2> for cnc?
[01:07:12] <ssi> nah, probably leave it manual
[01:07:13] <PetefromTn_> There is a guy local here that has two machines that look almost exactly like that
[01:07:13] <XXCoder> nicely foggy pics
[01:07:23] <PetefromTn_> yeah that would not be a candidate for CNC really.
[01:07:31] <zeeshan|2> why not
[01:07:46] <ssi> cause it's probably a nice manual lathe
[01:07:49] <ssi> and I need one of those :)
[01:07:51] <PetefromTn_> yeah basically
[01:07:55] <ssi> and I already have two cnc lathes
[01:07:58] <zeeshan|2> whats the diff between cnc lathe
[01:07:59] <zeeshan|2> and manual
[01:08:01] <PetefromTn_> it has all gear driven actions and whatnot
[01:08:06] <ssi> well look at pete's lathe for instance
[01:08:15] <ssi> it doesn't have all the change gears and leadscrew and everything
[01:08:19] <ssi> it's just a bed
[01:08:20] <XXCoder> one has "CNC" in place of "Manual". ;)
[01:08:21] <zeeshan|2> mine did
[01:08:22] <ssi> perfect for cnc
[01:08:25] <PetefromTn_> I mean you could CNC about anything
[01:08:25] <zeeshan|2> it had quick gear change box
[01:08:26] <zeeshan|2> power feed
[01:08:27] <zeeshan|2> etc
[01:08:29] <ssi> sure
[01:08:29] <zeeshan|2> i ripped it all off
[01:08:30] <zeeshan|2> =D
[01:08:37] <zeeshan|2> and just use a button to manually machine
[01:08:40] <PetefromTn_> but it would be a waste to make that one CNC
[01:08:46] <ssi> point is, I'm not gonna take a 70 year old nice manual lathe and throw all the manualy bits away
[01:09:00] <ssi> I'd rather use a grizzly if I were gonna do that
[01:09:00] <XXCoder> isnt there way to do both
[01:09:09] <ssi> and I've already done that :P
[01:09:10] <PetefromTn_> Hey man
[01:09:11] <zeeshan|2> XXCoder: yea its called handwheels w/ encoders
[01:09:12] <zeeshan|2> :P
[01:09:21] <PetefromTn_> I just spent most of the day underneath my house
[01:09:31] <XXCoder> sounds fun. buring bodies.
[01:09:35] -!- Demiurge has quit [Remote host closed the connection]
[01:09:47] <PetefromTn_> I would like to kick the ass of the guy who did the air conditioning install
[01:09:52] <zeeshan|2> ssi what lathes do you have
[01:09:52] <ssi> I spent all night last night cleaning up stuff
[01:09:55] <zeeshan|2> other than hnc
[01:09:56] <ssi> I cleaned up my tube amps and stuff
[01:10:00] <ssi> zeeshan|2: G0602
[01:10:10] <PetefromTn_> I basically removed half the return plenum
[01:10:10] <ssi> I had a clausing 6300 12x36 but I sold it to Dannifer
[01:10:23] <ssi> I cleaned up one of my basses that was hanging on the wall and real bad off
[01:10:23] <ssi> https://fbcdn-sphotos-e-a.akamaihd.net/hphotos-ak-xap1/v/t1.0-9/10425496_10100519846900152_6080753954434852054_n.jpg?oh=de246030f010a7f33d250926c92c131a&oe=551B63FD&__gda__=1424577704_9cb98d21e1632d20f3d43263c64f4333
[01:10:29] <zeeshan|2> whats the point of having 3 lathes
[01:10:30] <zeeshan|2> :D
[01:10:36] <ssi> after a lot of scrubbing and wax
[01:10:36] <ssi> https://scontent-a-lga.xx.fbcdn.net/hphotos-xfa1/v/t1.0-9/10703622_10100519876460912_1395401883298200434_n.jpg?oh=e0f818e5372e78c991fd741076d6ed8f&oe=54E8DA30
[01:10:41] <zeeshan|2> wow
[01:10:41] <PetefromTn_> nice
[01:10:46] <zeeshan|2> ssi to be honest with you
[01:10:50] <zeeshan|2> that looked cooled smoked
[01:10:50] <zeeshan|2> lol
[01:10:52] <zeeshan|2> *cool
[01:10:53] <PetefromTn_> are any of you guys good with sheetmetal?
[01:11:04] <ssi> I built an airplane from scratch :P
[01:11:05] <XXCoder> heh careful there is things that lose value with cleaning
[01:11:15] <PetefromTn_> well I have a serious question for yo.
[01:11:16] <PetefromTn_> you
[01:11:32] <ssi> my sheetmetal skills are not exactly the same as HVAC sheetmetal skills tho :P
[01:11:38] <PetefromTn_> basically all the duct work under my house is mostly rectangular
[01:12:08] <PetefromTn_> and the new unit has those square to round adapters so you can run the more efficient 14" round insulated ducting
[01:12:33] <PetefromTn_> so after removing all the laughable leaky, shitty plemun they built under there
[01:12:46] <PetefromTn_> I now have two rectangular duct openings
[01:12:50] <PetefromTn_> one for supply
[01:12:52] <PetefromTn_> one for return
[01:13:16] <PetefromTn_> I have to adapt both of them to the new unit which has two 14" round pieces of duct going into it.
[01:13:30] <PetefromTn_> I saw a couple videos on youtube about how to do that
[01:13:43] <PetefromTn_> but they used some fancy software
[01:13:54] <PetefromTn_> to figure the angles and bend locations
[01:14:25] <PetefromTn_> I was wondering if any of you guys know how to do this so I can get it designed and maybe get a .dxf of it and transfer the dims to real sheetmetal here
[01:14:36] -!- Meduza [Meduza!~meduza@addprofile.se] has joined #linuxcnc
[01:15:13] <PetefromTn_> I got the rest of it sorted out and we will be installing the new unit this week.
[01:16:27] <PetefromTn_> https://www.youtube.com/watch?v=pxhHBgPYdrM something like this
[01:16:47] <zeeshan|2> you can do that in inventor
[01:16:48] <zeeshan|2> or solidworks
[01:16:50] <PetefromTn_> https://www.youtube.com/watch?v=bYs4_STaQlU
[01:16:52] <zeeshan|2> using sheet metal module
[01:16:57] <PetefromTn_> that is a video showing the software
[01:17:45] <PetefromTn_> Basically what I need is that kind of transition only it has to be offset to the top or bottom. IE the round part is not in the middle of the rectangular part.
[01:18:00] <zeeshan|2> do you wanna do it with 2 sheet metal pieces
[01:18:01] <zeeshan|2> that you weld together
[01:18:03] <zeeshan|2> or 1 piece
[01:18:16] <PetefromTn_> probably two I will just rivet it together
[01:18:24] <zeeshan|2> do you know the dimensions
[01:18:27] <PetefromTn_> sure
[01:18:36] <PetefromTn_> the round is as said 14" diameter
[01:18:54] <PetefromTn_> the two rectangular plenums are 10x18 and 10x20
[01:19:21] <zeeshan|2> let me clarify
[01:19:22] <PetefromTn_> I started to draw it in freecad but I do not know how to unfold it once it is done
[01:19:33] <zeeshan|2> you need sheet metal module to do that
[01:19:37] <zeeshan|2> does freecad have it?
[01:19:41] <PetefromTn_> doubt it
[01:19:45] <zeeshan|2> are you doing 14" round ->? 10x18 for one
[01:19:50] <zeeshan|2> and anotehr is 14" round -> 10x20?
[01:19:55] <PetefromTn_> yeah
[01:20:00] <zeeshan|2> length of transition?
[01:20:11] <PetefromTn_> whatever makes the most sense..
[01:20:15] <zeeshan|2> haha
[01:20:20] <PetefromTn_> I am not limited by the distance
[01:20:38] <PetefromTn_> they are both pointing towards the unit which is like ten feet awar
[01:20:40] <PetefromTn_> away
[01:20:46] <PetefromTn_> say 24" or so?
[01:21:06] <PetefromTn_> less if possible to get the most efficient use of materials
[01:21:11] <PetefromTn_> and easiest bends.
[01:21:22] <PetefromTn_> This shit is thin so that is not really a problem.
[01:21:37] <PetefromTn_> do you have sheetmetal module?
[01:21:40] <zeeshan|2> what is material thickness
[01:21:40] <zeeshan|2> yea
[01:21:51] <PetefromTn_> hang on I will measure it.
[01:23:11] <PetefromTn_> Looks like about .023"
[01:24:10] <PetefromTn_> probably 24 gauge
[01:25:28] <PetefromTn_> You can see in that video they made some like 1" flanges in the ends of the rectangular part.
[01:25:39] <PetefromTn_> That would make it much easier to attach it
[01:26:26] <PetefromTn_> I am gonna call this AC shop down the hill from me in the morning to see what they might charge to make them but I have a BUNCH of sheetmetal here from the old plenum shit I removed that I can probably use to make my own.
[01:28:31] -!- AR_ [AR_!~AR@] has joined #linuxcnc
[01:28:47] <PetefromTn_> ssi You gonna buy that lathe?
[01:31:29] <zeeshan|2> pete
[01:31:32] <zeeshan|2> i have it made
[01:31:40] <zeeshan|2> but the thing is i dont get where you want the flanges
[01:31:42] <zeeshan|2> on the rect part
[01:32:10] <PetefromTn_> well the first thing is like I said it needs to be oriented offset to one side of the rectangular part.
[01:32:11] <zeeshan|2> lemme show you apic
[01:32:34] <PetefromTn_> In other words the edge of the round has to be parallel to one of the long edges of the rectangle
[01:32:45] <PetefromTn_> BTW thanks for doing that
[01:32:50] <PetefromTn_> I appreciate it
[01:33:11] <zeeshan|2> np
[01:33:13] <zeeshan|2> i hope this is what u need
[01:33:27] <zeeshan|2> http://i.imgur.com/so7ATzD.png
[01:33:32] <zeeshan|2> is that the shape?
[01:34:11] <zeeshan|2> oh
[01:34:11] <zeeshan|2> shit
[01:34:29] <PetefromTn_> yup I think so but it is hard to tell if the round part edge is inline with one of the square edges
[01:35:03] <zeeshan|2> can you tell me the video
[01:35:06] <PetefromTn_> basically the round part has to be offset the four inches from the long edge across from it on one side.
[01:35:07] <zeeshan|2> and wart part
[01:35:17] <PetefromTn_> hang on.
[01:35:22] <zeeshan|2> *what
[01:38:09] <PetefromTn_> https://www.youtube.com/watch?v=bYs4_STaQlU In this video at .26 you can see a small picture of the duct preview in the top left of the screen. YOu can see how the round hole is offset from the center and from the side
[01:38:29] <zeeshan|2> yes
[01:38:42] <PetefromTn_> Basically I need the round hole in the center of the long axis and offset to the top or bottom in the short side 10" dimension.
[01:38:42] <zeeshan|2> how much of an offset do you need
[01:39:10] <PetefromTn_> whatever puts the round hole even with the long side 18" or 20" depending on which one you are drawing first
[01:39:19] <zeeshan|2> ok lemme show you an image
[01:39:23] <zeeshan|2> thatll clarify it a bit better
[01:39:27] <PetefromTn_> trying to find you a picture to represent
[01:39:59] <PetefromTn_> at 1:53 in that video you see the side view that is exactly what I need
[01:40:23] <zeeshan|2> okayt you want it shifted to the right
[01:40:33] <zeeshan|2> is it okay if its like 1" away
[01:40:34] <zeeshan|2> from the corner?
[01:40:47] <PetefromTn_> yeah I need it 90 degrees on one side that is the long side.
[01:40:55] <PetefromTn_> but centered on the long edge
[01:41:56] <PetefromTn_> hard to describe I guess
[01:42:06] <PetefromTn_> if you look at it from the round hole side
[01:42:21] <PetefromTn_> the edge of the round hole will be even with the middle of one of the long edges
[01:42:42] <PetefromTn_> and the round hole will be centered along the length of the long edge from side to side
[01:43:58] <zeeshan|2> http://i.imgur.com/tka24Ir.png
[01:44:01] <zeeshan|2> kinda like that?
[01:45:23] <PetefromTn_> unfortunately not really the rectangular part would need to be centered on the round part....and the top edge of the round part would touch the top edge of the rectangular part
[01:46:04] <zeeshan|2> hm
[01:46:20] <zeeshan|2> but the diameter is 14"
[01:46:23] <PetefromTn_> so the bottom half you did not show would be a larger piece due to the offset
[01:46:25] <zeeshan|2> and the rect part is 10"
[01:46:29] <PetefromTn_> yeah
[01:47:03] <zeeshan|2> might be easier to do it with just one piece then :P
[01:47:27] <PetefromTn_> basically just like in that video I just posted but the round part needs to be in the middle of the long direction
[01:47:56] <zeeshan|2> yea but its bit eaasier for him
[01:48:02] <zeeshan|2> cause the tube is smaller than the rect
[01:48:23] <PetefromTn_> yeah I know
[01:48:38] <zeeshan|2> what makes it challenging is
[01:48:41] <zeeshan|2> one part is expanding
[01:48:45] <zeeshan|2> while another part is collapsiing
[01:48:47] <zeeshan|2> if you kow what i mean
[01:49:02] <PetefromTn_> ssi http://knoxville.craigslist.org/tls/4721684300.html looks like a nice machine here too..
[01:49:21] <PetefromTn_> yeah I know that is why I was hoping to get a cad drawing done.
[01:49:31] <PetefromTn_> I thought about using cardboard to try to build it
[01:49:37] <PetefromTn_> then transfer it to sheetmetal
[01:50:19] <PetefromTn_> Lemme work on a 3d model of what I need and maybe I can just send you that and you can use it easier?

[01:54:43] <zeeshan|2> sounds good
[01:55:43] <zeeshan|2> can you check this out
[01:56:05] <zeeshan|2> http://i.imgur.com/ORekOqL.png
[01:56:07] <zeeshan|2> like that i hope?!?!
[01:56:22] <zeeshan|2> or does the top of the circle
[01:56:27] <zeeshan|2> have to be exactly tangent
[01:56:31] <zeeshan|2> to the rect line
[01:57:02] <zeeshan|2> nm
[01:57:08] <zeeshan|2> i changed it to tangent
[01:57:10] <zeeshan|2> and it works
[01:57:35] <PetefromTn_> yeah if the rectangle was touching the top of the circle it would be what I need
[01:57:50] <PetefromTn_> working on the drawing right now but that is basically it.
[01:58:07] <PetefromTn_> The bottom half if split on the 10" side would be larger than the top halp
[01:58:08] <PetefromTn_> half
[01:58:36] <zeeshan|2> http://i.imgur.com/573wYKk.png
[01:58:46] <PetefromTn_> it's basically a loft op
[01:58:57] <zeeshan|2> yes
[01:59:53] <PetefromTn_> yeah that last one is it. as long as the square dimensions are 10x18 or 10x20 and the round is 14"
[02:00:49] <zeeshan|2> its not liking it
[02:00:53] <zeeshan|2> not wanting to flat pattern
[02:01:09] <PetefromTn_> hm
[02:01:26] <PetefromTn_> as long as it is close to level with the top edge it should be fine.
[02:02:01] <zeeshan|2> ok it worked
[02:02:02] <zeeshan|2> it was my fault
[02:02:03] <zeeshan|2> lol
[02:02:03] <PetefromTn_> The duct is strapped to the bottom of the floor joists suspended a few inches underneath it so if it was just centered it would not be able to be installed because the top edge would hit the joists
[02:03:27] <zeeshan|2> im just confirming if the flat pattern makes sense
[02:03:42] <PetefromTn_> no hurry here LOL
[02:04:17] <zeeshan|2> yea the flat pattern makes no sense
[02:04:18] <zeeshan|2> haha
[02:07:20] -!- Tecan [Tecan!~fasdf@unaffiliated/unit41] has joined #linuxcnc
[02:07:20] <zeeshan|2> there we go!
[02:07:23] <zeeshan|2> how many b end lines do you want
[02:07:24] <zeeshan|2> for the curve
[02:07:37] <PetefromTn_> as few as possible to make it work right
[02:07:51] <PetefromTn_> I don't have a brake here so I will be doing it the hard way
[02:07:52] <zeeshan|2> well think of it like this
[02:07:59] <zeeshan|2> you got a circle
[02:08:07] <zeeshan|2> if you do 8 bend lines total
[02:08:12] <zeeshan|2> you have 8 flat portions on that curve
[02:08:13] <PetefromTn_> http://i.imgur.com/jR4dTiy.jpg
[02:08:34] <PetefromTn_> yeah I understand the concept
[02:08:41] <zeeshan|2> so you gotta make the call
[02:08:44] <PetefromTn_> probaly like ten or so five from each side
[02:08:55] <zeeshan|2> okay make a 10 sided polygon in freecad
[02:08:59] <zeeshan|2> and see if it looks okay to you
[02:08:59] <zeeshan|2> :D
[02:09:07] <PetefromTn_> should allow me to get it done and not be bending for days
[02:09:12] <zeeshan|2> haha
[02:09:17] <PetefromTn_> no I know what it will look like;
[02:09:32] <PetefromTn_> I just don't have the software to make it unfold
[02:09:45] <PetefromTn_> so I can use the .dxf to create the real thing here in the shop
[02:10:21] <zeeshan|2> http://i.imgur.com/LwpSqNO.png
[02:10:23] <PetefromTn_> you see I bought a couple 14" round adapter rings that have sheetmetal fingers all the way around for riveting or screwing it in
[02:10:25] <zeeshan|2> does that look ok?
[02:10:41] <zeeshan|2> looks like a nightmare to me :D
[02:11:04] <PetefromTn_> looks like twelve which should be fine actually
[02:11:07] <ssi> PetefromTn_: that clausing does look nice, although it's hard to tell with atht one blurry picture
[02:11:10] <Connor> ssi murphy oil soap works good on smoked covered stuff.. I know from exp.
[02:11:17] <zeeshan|2> PetefromTn_: its gotta be a multiple of 4
[02:11:22] <ssi> yeah
[02:11:24] <PetefromTn_> okay that is fine
[02:11:26] <zeeshan|2> for each quadrant of the circle
[02:11:34] <zeeshan|2> okay thats the 10x18
[02:11:48] <zeeshan|2> lemme send you the DXF
[02:11:56] <PetefromTn_> ok
[02:12:12] <PetefromTn_> so that is half right which half is it?
[02:12:23] <zeeshan|2> no thats the whole thing
[02:12:37] <PetefromTn_> oh sorry you are right
[02:12:46] <zeeshan|2> all you gotta do is rivet it
[02:12:47] <zeeshan|2> at the end
[02:12:59] <PetefromTn_> yeah
[02:13:05] <PetefromTn_> I can split it If I need to
[02:13:09] <zeeshan|2> yes
[02:13:14] <PetefromTn_> wish I had a bigass plotter here LOL
[02:13:18] <zeeshan|2> yea man
[02:13:21] <ssi> I have a bigass plotter :P
[02:13:22] <zeeshan|2> you could print it out
[02:13:25] <zeeshan|2> and test it on a piece of paper first
[02:13:25] <zeeshan|2> haha
[02:13:26] <ssi> I need ink cartridges for it
[02:13:41] <PetefromTn_> that would be easiest
[02:13:48] <PetefromTn_> but I will have to do it the hard way
[02:14:01] <PetefromTn_> laying it all out on the metal from dims from the .dxf
[02:14:09] <PetefromTn_> what does the solid model look like>
[02:15:04] <zeeshan|2> http://i.imgur.com/vAQtdJn.png
[02:15:09] <zeeshan|2> theres an extra line theere
[02:15:12] <zeeshan|2> cause its the split line
[02:15:32] <PetefromTn_> that looks beatiful man
[02:15:35] <zeeshan|2> this is one of those drawings
[02:15:37] <PetefromTn_> exactly what I need
[02:15:43] <zeeshan|2> that you hope to god you'll never have to draw in drafting class
[02:15:44] <zeeshan|2> by hand
[02:15:45] <PetefromTn_> thank you
[02:15:47] <zeeshan|2> np man
[02:15:51] <zeeshan|2> 10x18
[02:15:54] <zeeshan|2> what was the other one
[02:15:58] <PetefromTn_> 10x20
[02:16:06] <PetefromTn_> exactly the same orientation
[02:16:09] <zeeshan|2> okay
[02:16:37] <PetefromTn_> it's too bad ssi is so far away I could have him burn it for me on the plasma and then I would just need to bend the friggin thing
[02:17:32] <ssi> if my plasma was set up :P
[02:17:46] <ssi> the water table is actually out at the coaters getting blasted and powder coated
[02:17:54] <zeeshan|2> i forget
[02:17:57] <zeeshan|2> if i save it as dxf
[02:17:59] <zeeshan|2> and im using 1:8 scale
[02:18:02] <zeeshan|2> will it show up on your end?
[02:18:32] <zeeshan|2> im gonna leave one dimension in there
[02:18:36] <zeeshan|2> it should say 17.5"
[02:18:38] <zeeshan|2> and measure it
[02:18:43] <zeeshan|2> just double check
[02:19:09] <PetefromTn_> you can't save it 1-1?
[02:19:33] <PetefromTn_> I can just scale it here in .dxf form I guess
[02:19:42] <zeeshan|2> i wouldnt want you scaling it on your end
[02:19:48] <zeeshan|2> ive had some bad experience with tha tbefore
[02:19:54] <PetefromTn_> ?
[02:19:56] <zeeshan|2> if that one line measures 17.5"
[02:20:05] <zeeshan|2> we're good!
[02:20:23] <PetefromTn_> what was the total length you wound up using?
[02:20:36] <zeeshan|2> 24
[02:20:42] <PetefromTn_> okay
[02:21:19] <zeeshan|2> should i email these
[02:21:25] <PetefromTn_> sure
[02:22:40] <PetefromTn_> this will be much more efficient and smoother than just adding a freakin' box like the other guys did. More work but I think it will be worth it.
[02:23:05] <PetefromTn_> I will just add the flanges of like 1.5" to the rectangular end before I try to cut it out.
[02:23:22] <PetefromTn_> Probably cut it from cardboard first to make sure it will work.
[02:23:38] <PetefromTn_> ssi that is a nice looking clausing tho huh?
[02:23:51] <PetefromTn_> If I had 3k laying around I would go look at it I think,
[02:24:03] <PetefromTn_> probably get it for $2500
[02:27:29] -!- FreezingCold [FreezingCold!~FreezingC@] has joined #linuxcnc
[02:29:15] <zeeshan|2> yea id definitely do it with cardboard first
[02:29:19] <zeeshan|2> i was making this:
[02:30:20] <zeeshan|2> http://i130.photobucket.com/albums/p252/turbozee84/sheetmetal_zps667cac4d.png
[02:30:23] <zeeshan|2> for an intercooler pipe
[02:30:25] <zeeshan|2> weird ass transition
[02:30:32] <zeeshan|2> i printed that out
[02:30:36] <zeeshan|2> and layed it on the pipe and traced it
[02:30:54] <zeeshan|2> it still needd like about 1/16-1/8" of clean up
[02:30:54] <PetefromTn_> yeah it would be nice to have those capabilities
[02:30:57] <zeeshan|2> to get a perfect fit
[02:31:06] <PetefromTn_> I usually just cave man it
[02:31:22] <zeeshan|2> i used to too to be honest
[02:31:34] <zeeshan|2> but after i wasted some stainless tubing
[02:31:39] <zeeshan|2> i was like f it!
[02:31:41] <PetefromTn_> but for something like this I wanted to try to make sure I got it right since it is going to ensure my house is energy efficient
[02:32:30] <PetefromTn_> I also only have a certain amount of sheetmetal here to play with so screwing one up would make me have to reach into my poscket some more
[02:32:51] <zeeshan|2> http://i130.photobucket.com/albums/p252/turbozee84/ypipe_zps6992c98a.png
[02:32:54] <zeeshan|2> this was another weird one
[02:33:00] <zeeshan|2> trying to figure out how to cut the transition right
[02:33:33] <zeeshan|2> i ended up cave manning that one
[02:34:39] <zeeshan|2> i sent the dxfs
[02:34:44] <zeeshan|2> plz lemme know if they open right
[02:34:48] <zeeshan|2> one dimension should be 17.5
[02:34:53] <zeeshan|2> the other should be 19.5 (for the 10x20)
[02:35:02] <PetefromTn_> look good so far.
[02:35:04] <PetefromTn_> BRB
[02:35:09] <PetefromTn_> Gotta put my kids to bed
[02:52:21] <PetefromTn_> well the 17.5" dimension shows the same in my program so it's all good.
[02:55:54] <PetefromTn_> neato
[02:56:13] <PetefromTn_> the bend angles actually already have the dimension angles listed

[03:21:48] <PetefromTn_> bring it up here man LOL

[03:21:57] <ssi> easier
[03:24:05] <zeeshan|2> PetefromTn_
[03:24:09] <zeeshan|2> you have a box and pan brake?
[03:24:16] <PetefromTn_> nope LOL
[03:24:21] <zeeshan|2> they confuse me
[03:24:26] <zeeshan|2> theres so many different kinds
[03:24:29] <zeeshan|2> i never know which one to buy
[03:24:31] <Connor> I want a 24" one..
[03:24:45] <ssi> we have a 48" enco box brake here
[03:24:46] <ssi> but it mostly sucks
[03:25:03] <zeeshan|2> whats the biggest length of the box
[03:25:05] <zeeshan|2> you can maake
[03:25:07] <zeeshan|2> length = depth
[03:25:17] <ssi> I dunno
[03:25:21] <zeeshan|2> the ones were at eaton were quite different
[03:25:22] <Connor> http://www.grizzly.com/products/24-Box-and-Pan-Brake/G0557
[03:25:26] <zeeshan|2> i dont think theyre called box and pan brakes
[03:25:26] <Connor> that's the one I want.
[03:25:45] <zeeshan|2> http://www.jps-machinery.co.uk/wp-content/uploads/2013/03/Hydraulic-press-brake-2.jpg
[03:25:47] <zeeshan|2> it was like that
[03:25:48] <Connor> G0557 24" Box and Pan Brake
[03:25:56] <zeeshan|2> is that still considered a "box and pan brake"
[03:25:57] <zeeshan|2> lol
[03:26:04] <zeeshan|2> i just called it a "brake press"
[03:26:05] <PetefromTn_> they make a large combo machine I would not mind having but they will not genereally do anything real thick
[03:26:17] <ssi> I would try to find the one we have on the enco site
[03:26:18] <Connor> If it has fingers that can be removed.. then yes.. it's a box and pan brake
[03:26:18] <ssi> but it blows
[03:26:26] <ssi> unknown word
[03:26:27] <ssi> We were unable to find an exact match for your search for "BRAKE"
[03:26:31] <zeeshan|2> yea you can remove the fingers
[03:26:32] <zeeshan|2> and adjust them
[03:26:36] <zeeshan|2> and put different types of dies
[03:26:54] <PetefromTn_> I would rather have a nice big press brake
[03:26:57] <zeeshan|2> like i never understood why these things needed to be so huge
[03:27:02] <zeeshan|2> like it looks like it weighs 15,000 lb
[03:27:03] <zeeshan|2> or more
[03:27:09] <Connor> PetefromTn_: 48" ?
[03:27:10] <zeeshan|2> yet a box and pan brake 48" is like..
[03:27:12] <zeeshan|2> 1000 lb
[03:27:33] <ssi> ours is way less than that even
[03:27:35] <Connor> zeeshan|2: Thickness of material you can bend dictates it's mass
[03:27:36] <ssi> maybe 500lb
[03:27:39] <zeeshan|2> connor
[03:27:45] <zeeshan|2> these things did like .185" max
[03:27:47] <zeeshan|2> or .2"
[03:27:55] <zeeshan|2> that doesnt seem like a lot
[03:28:05] <ssi> it doesn't?
[03:28:06] <ssi> heh
[03:28:12] <PetefromTn_> http://img.directindustry.com/images_di/photo-g/hydraulic-presses-brake-cnc-113373-5558131.jpg
[03:28:21] <zeeshan|2> no it doesnt
[03:28:24] <zeeshan|2> when you consider hydraulics
[03:28:38] <Connor> STEEL ?
[03:28:38] <zeeshan|2> yes something like ete posted
[03:28:47] <zeeshan|2> is what i imaged something that can easily do .2" steel
[03:28:48] <Connor> That's damn thick to be bending.
[03:28:48] <zeeshan|2> no prob
[03:28:53] <roycroft> that's quite a bit when you're talking about a sheet metal brake
[03:29:03] <PetefromTn_> http://www.bangshift.com/assets/images/news/2009/May/10-16/press%20brake.jpg
[03:29:06] <roycroft> and when you're talking 1000lbs you're talking about a sheet metal brake
[03:29:13] <ssi> it's one thing to bend a piece of 1/4" steel thats's 2-3" wide
[03:29:20] <ssi> it's another hting entirely to bend 48" of 1/4" steel
[03:29:31] <zeeshan|2> i know!
[03:29:36] <zeeshan|2> i calculated the forces before
[03:30:09] <Connor> Anywho... the little 24" would suit my needs.. just not sure where I would put it.
[03:30:16] <zeeshan|2> maybe its something to do with distortion
[03:30:17] <zeeshan|2> and not forces
[03:30:37] <zeeshan|2> like yea the metal might not yield at 50 ton force
[03:30:47] <zeeshan|2> (the frame of the brake press)
[03:30:48] <zeeshan|2> but it might flex
[03:31:35] <roycroft> i had to bend some 0.120" 304 ss a couple weeks ago
[03:31:40] <roycroft> the pieces were about 2" wide
[03:32:16] <roycroft> i milled a vee groove in the pieces at the bend point 0.060" deep
[03:32:42] <roycroft> my 30" 3 in one sheet metal machine just about broke trying to do the bend
[03:33:16] <roycroft> it's rated to bend 20ga ss at full width

[03:52:03] <zeeshan|2> yo ssi
[03:52:09] <zeeshan|2> is there anyway to interface the brake for z axis
[03:52:11] <zeeshan|2> with amc drives?
[03:54:35] <ssi> not those drives
[03:54:43] <ssi> just have the same enable drive a relay
[03:55:00] <ssi> https://scontent-a-ord.xx.fbcdn.net/hphotos-xap1/v/t1.0-9/9766_10100520524791652_4657380844245345821_n.jpg?oh=c70992eaa2662bc8482777750adb367a&oe=54E650DD
[03:55:43] <zeeshan|2> my enable signal comes right from mr 7i77
[03:55:50] <ssi> sure
[03:55:52] <zeeshan|2> and i think its limited to 300mA
[03:55:59] <zeeshan|2> so youre saying throw a relay in between
[03:56:23] <zeeshan|2> a 1-2 s delayed relay that is
[03:56:26] <zeeshan|2> (like pete was talking about)
[03:56:35] <ssi> I dunno that I'd delay it that long
[03:56:53] <zeeshan|2> i mean delay the enable
[03:56:55] <zeeshan|2> by 1-2 sec
[03:56:59] <zeeshan|2> wait wtf am i saying
[03:57:18] <zeeshan|2> i want the brake to enable for a small duration
[03:57:30] <zeeshan|2> till axis is enabled
[03:57:34] <PetefromTn_> You probably need to look into having linuxCNC output another signal to enable the relay a second or two BEFORE the enable signal goes off
[03:57:42] <ssi> that's easy
[03:57:45] <ssi> well
[03:57:54] <ssi> before isn't easy
[03:57:56] <zeeshan|2> PetefromTn_: is that how youre doing it on the cinci?
[03:58:00] <ssi> but honestly I don't think it'd be that big a deal
[03:58:19] <PetefromTn_> no as I said my drives take care of that internally but that is basically how it works
[03:58:30] <zeeshan|2> f it
[03:58:36] <zeeshan|2> disable brake
[03:58:40] <zeeshan|2> at the same time enabling drive
[03:58:41] <zeeshan|2> see what happens
[03:58:43] <zeeshan|2> :-)
[03:58:52] <ssi> they can't know that you're disabling them before you disable them
[03:58:59] <PetefromTn_> mine would drop about a quarter inch or so.
[03:59:00] <zeeshan|2> ssi well
[03:59:03] <zeeshan|2> asap it gets an enable signal
[03:59:06] <PetefromTn_> probably more
[03:59:07] <zeeshan|2> you can start a timer
[03:59:15] <zeeshan|2> before the actual enable happens
[03:59:17] <ssi> and I certainly wouldn't want them to keep the drive enabled

[04:00:09] <PetefromTn_> enabling the drives is the easy part it is disabling the drives and applying the brake the causes the drop
[04:00:29] <zeeshan|2> oh
[04:00:36] <zeeshan|2> well remember
[04:00:38] <zeeshan|2> my brake is normally closed
[04:00:41] <zeeshan|2> so its always on
[04:00:43] <PetefromTn_> if they happen simultaneously the head drops a little bit before the brake can engage
[04:01:05] -!- sumpfralle has quit [Ping timeout: 264 seconds]
[04:01:14] <zeeshan|2> until you press 24vdc through it and i think that disables it
[04:01:22] <zeeshan|2> i have still to test it
[04:01:33] <PetefromTn_> the brake should be engaged whenever power is NOT applied to it.
[04:01:40] <zeeshan|2> PetefromTn_: yes
[04:01:54] -!- mk0 has quit [Client Quit]
[04:02:05] <PetefromTn_> when you enable the drive the power is turned on DIS engaging the brake
[04:02:07] <zeeshan|2> ill try it out without any delay
[04:02:11] <zeeshan|2> if its got an issue, ill add a delay
[04:02:19] <PetefromTn_> works for me
[04:02:43] <zeeshan|2> what happens if you dont disable the brake
[04:02:47] <zeeshan|2> and try to run the servo? :D
[04:02:59] <zeeshan|2> is that a good way to blow up your 24vdc power supply
[04:03:00] <PetefromTn_> Like I said my head dropped about a quarter inch before we played with the delay in the drives settings
[04:03:49] <zeeshan|2> that can be pretty dangerous :P
[04:03:52] <PetefromTn_> now when I hit the servo on/off button in linuxCNC there is a little click and you can hear the brake engage and then you can hear the servo depowering a moment later
[04:03:58] <zeeshan|2> especially if your end mill is sitting 1/4" above your work piece!

[16:01:44] <mozmck> LXDE generally has *less* features than XFCE, so that may not be what you want.

[16:05:04] <FinboySlick> Actually, it might be cool to collaborate with linuxcnc.
[16:05:12] <jthornton> lxde seems grainy lacks the bottom bar with the open windows
[16:05:13] * FinboySlick joined the lxde team recently.
[16:05:42] <mozmck> I like LXDE too. Using XFCE right now with Nemo for my file manager though :)
[16:05:42] <FinboySlick> jthornton: There's a task bar in lxde by default.
[16:05:59] <jthornton> it's at the top
[16:06:14] * jthornton has been using ubuntu for too long
[16:06:15] <mozmck> move it to the bottom!
[16:06:15] <FinboySlick> jthornton: Oh, well, you can change that with a couple clicks.
[16:06:57] <cradek> jthornton: rest assured, ubuntu isn't what you want anymore either :-/
[16:07:08] <mozmck> heh, I agree.
[16:07:32] <mozmck> I'm using linux mint 17, xfce, with Nemo for a file manager. my own "hybrid" :)
[16:07:33] <archivist> win8 cures anybody of windows
[16:07:46] <ssi> win98 cured me of windows :)
[16:08:10] <cradek> os/2 warp cured me of windows
[16:08:18] <cradek> (it was a very long time ago)
[16:09:11] <archivist> I never ran os/2
[16:09:43] <cradek> it did some neat things we still don't have anywhere
[16:10:08] <mozmck> I liked os/2 warp as well.
[16:11:51] <archivist> I got unixed way back before linux existed, on an Altoss 1000 with ATT Unix 386 with 12 meg of memory iirc

[16:12:58] <archivist> I want to get the Altos back up and running one day
[16:14:15] * JT-Shop figured out how to add another panel but not how to attach it to the screen edge lol
[16:14:33] <archivist> 8k is enough for some powerful software
[16:18:35] <PetefromTn_> I have Ubuntu on the Cinci... Been thinking about making my laptop run linux or at least a dual boot

[16:26:15] <archivist> the laser also cooks the the food extruded /me patents that idea
[16:26:23] <ssi> archivist: that idea has been around awhile
[16:26:34] * archivist sues
[16:26:44] <ssi> that said, I experimented with cutting foodstuffs with a laser, and it makes them taste like shit
[16:26:55] <CaptHindsight> if only we could find a way to make these things from dog turd
[16:27:07] <archivist> with added burnt taste
[16:27:31] <archivist> hey no polishing turds

[16:39:39] <rootB> CaptHindsight, I own a desktop CNC router (shapeoko, i've done some modifications to it) and im trying to mill some pine wood. On my various attempts, i have to reduce the cut feedrate due to the fact that my bit either gets stuck on the wood or the wood comes out awful.
[16:39:46] <CaptHindsight> what are they actually making there besides art projects?
[16:39:53] <t12> that is unclear

[16:40:51] <ssi> I have more machines than I reasonably ought to
[16:40:55] <t12> its a big show
[16:40:56] <ssi> and I do next to nothing with them
[16:41:06] <t12> lately after working for enough hypey startups though i've found
[16:41:09] <rootB> My machine is using a dewalt DW660 as a spindle which has a 30,000rpm speed.
[16:41:12] <t12> sometimes its both a hype show and maybe real
[16:41:16] <t12> or has potential to be real
[16:41:38] <ssi> shit I'd love to see the 3d printer weenies release some decent 3d machining cad/cam
[16:41:38] <t12> I heard that mori-seki was more or less refusing to give that pier 9 facility the vmc they got
[16:41:46] <t12> because they wanted them to be on produciton lines not on showfloors
[16:41:49] <archivist> rootB, and depth of cut
[16:42:00] <t12> by give i mean allowing them to purchase, not give
[16:42:12] <rootB> archivist, the depth im trying to cut is 19mm
[16:42:24] <archivist> rootB, you need to be able to clear the chips and dust out
[16:42:31] <PetefromTn_> some deep pockets at work there to be sure...
[16:43:01] <t12> I think another way to look at it is
[16:43:04] <archivist> 19 is a lot for a small cutter
[16:43:16] <t12> that they think that the training ground for the next generation of eng's will be the maker world

[16:46:26] <rootB> archivist, i was doing cut depths of 1mm with a cu feedrate of 35 and plunge feedrate of 10
[16:46:31] <rootB> could that been a mistake too?
[16:46:36] <CaptHindsight> t12: on the other hand I also work with top university and gov labs that also can't seem to make things that work either

[16:47:32] <CaptHindsight> management thinks and engineer is an engineer, there's no difference
[16:48:20] <Rab> rootB, is this the tool you're using? http://www.amazon.com/gp/product/B00004UDIB/
[16:48:32] <rootB> i think Rab
[16:48:35] <rootB> looks a lot like it
[16:49:16] <Rab> rootB, that's a downcut bit. It's meant to penetrate through the work; using it as an endmill packs chips down into the cut.
[16:51:05] <rootB> oh
[16:51:12] <archivist> and if you use that small a tool you are probably blunting it and just creating heat
[16:51:49] <Rab> Yeah, that particular tool is HSS.
[16:51:58] <rootB> So
[16:52:07] <rootB> all the bits that came on my dremel are downcut bits?
[16:52:09] <rootB> meant to penetrate?
[16:52:45] <archivist> dremel bits are for light duty not for heavy work
[16:53:07] <rootB> so i guess they're not meant for milling at all?
[16:53:11] <Rab> rootB, that particular one is, and I know it comes in a lot of Dremel kits. I don't know if they supply other endmills. But you can easily tell upcut vs downcut by the direction of the flutes vs the motor rotation.
[16:53:37] <Rab> rootB, it's meant for sawing drywall and thin laminate.
[16:53:39] <rootB> I'm very new when it comes to milling so im still learning my 101.
[16:53:47] <rootB> fuck.. that explains a lot.
[16:54:09] <rootB> A LOT.
[16:55:00] <renesis> ha
[16:55:10] <renesis> thats not an endmill, its a router bit
[16:55:29] <Rab> Sawing drywall, you want the "chips" to go out the other side instead of into your face.
[16:55:32] <renesis> for wood, blows chips down
[16:55:59] <renesis> do they work very long in drywall?
[16:56:10] <rootB> thanks a lot linuxCNC
[16:56:14] <Rab> Most all endmills you can find will be upcut, with a very few exceptions for specific cases.
[16:56:28] <cpresser> on the 7i76, its possible to attach a MPG to inputs 16-19. but where would i get the +5V needed for the mpg to operate?
[16:56:32] <rootB> http://www.amazon.com/Amana-Tool-45200-Straight-Diameter/dp/B000K2DO9W
[16:56:35] <rootB> this is the bit im going to use
[16:56:37] <rootB> is this one ok?
[16:57:00] <CaptHindsight> rootB: the cut material has to go somewhere, it doesn't evaporate
[16:57:16] <cpresser> the inputs are isolated field-inputs, so using the +5V from one of the step/dir interfaces doesnt seem right
[16:57:25] <CaptHindsight> evaporate/disappear
[16:57:39] <ssi> cpresser: also I wonder if they'll trigger at 5v if you're running 12 or 24v field voltage
[16:57:47] <rootB> Yeah, now i understand CaptHindsight
[16:57:50] <Rab> rootB, see how the flutes don't spiral on that tool? It won't clear the chips.
[16:57:54] <cpresser> the MPG manual only says '5V operation'
[16:57:55] <ssi> cpresser: the regular field inputs trip at like 60% field voltage, or something along those lines
[16:58:10] <cpresser> the input threshold on those special pins is 2.5V
[16:58:14] <ssi> ok
[16:58:15] <rootB> Yeah Rab.
[16:58:22] <pcw_home> Yes they have a fixed 2.5 v threshold when used for MPGs
[16:58:24] <rootB> So the spirals in the bit are for clearing the chips?
[16:58:48] <Rab> rootB, correct.
[16:58:59] <Rab> rootB, this might work: http://www.amazon.com/Kodiak-Diameter-Flute-Solid-Carbide/dp/B0070YYL40/

[17:00:30] <Rab> rootB, an 1/8" diameter tool is going to be very delicate. 1mm depth of cut should be fine. 30K RPM spindle pretty much limits you to small diameter tooling.
[17:01:00] <rootB> oh well
[17:01:17] <rootB> it's 8 dollars so im going to buy it
[17:01:18] <Rab> rootB, that one definately will work, much better than the Dremel tool. But if you crash or overstress it, it will break.
[17:01:19] <rootB> and try it
[17:01:37] <rootB> Yeah i suppose that if i crash and overstress it, it's going to pop
[17:01:58] <Rab> rootB, worth a shot. You can find cheaper tooling on eBay, but you might have to wait for it.
[17:02:21] <ssi> I went to frys saturday and they had meanwell 25W 5V frame supplies on sale for $6.99 each
[17:02:24] <ssi> so I bought all of them :D

[17:05:25] <Rab> rootB, I like this eBay seller for carbide micromachining tools. Notice the price difference, as well as the range of tooling available: http://stores.ebay.com/carbideplus
[17:05:58] <cpresser> pcw_home: sure? that doesnt seem to match the manual: " channels, field voltage analog in, and
[17:06:01] <cpresser> 2 MPG encoders on inputs 16..19). Default encoder count mode is 1X to
[17:06:03] <cpresser> match normal 100 PPR MPGs. Encoder input threshold is fixed at 2.5V for
[17:06:06] <cpresser> compatibility with 5V encoder outputs."
[17:06:28] <pcw_home> it is for the MPG but not the input bits
[17:06:42] <cpresser> ah okay. now i do understand :)
[17:07:02] <ssi> I don't follow that
[17:07:05] <pcw_home> all inputs are analog so all thresholds are software
[17:07:10] <ssi> OH i see
[17:07:13] <rootB> there's a lot of variety, Rab
[17:07:26] <cpresser> does the dsPIC run with 5V? if yes, how much additional current draw does its supply allow?
[17:07:28] <ssi> thats nuts; I didn't realize the field inputs were all analog
[17:07:39] <pcw_home> 3.3v
[17:07:47] <Rab> rootB, sure. You need different tooling for different materials and types of cuts. For wood, it doesn't matter as much.

[17:51:24] <jdh> mcmaster?
[17:51:47] <ssi> but I can get this one overnight
[17:51:47] <ssi> http://www.amazon.com/3M-16587-Accuspray-Spray-Gun/dp/B00AJVE1ZU/ref=sr_1_6?ie=UTF8&qid=1415641893&sr=8-6&keywords=3m+accuspray
[17:52:44] <ssi> mcmaster doesn't carry them I don't think
[17:52:52] <CaptHindsight> an auto body shop supplier will probably be the same or more but in stock today
[17:54:40] <koss> http://www.amazon.com/exec/obidos/ASIN/B00829R6WQ/fpv-20/
[17:54:44] <koss> ^ lol nice "spray gun"
[17:54:50] <koss> funny the pic on the preview page was correct
[17:54:55] <ssi> ha
[17:55:07] <ssi> when all you have is a hammer, everything looks like a spray gun
[17:56:15] <CaptHindsight> you can get a Graco gun at ~60 locations around Atlanta
[17:57:02] <CaptHindsight> did you check with any 3M dealers in the area?
[17:58:12] <ssi> according to 3m's site, all the 3m dealers in atlanta are west marine :P
[17:58:43] <ssi> oh that's 3m marine products haha
[17:58:48] <ssi> THAT MAKES MORE SENSE
[17:59:12] <ssi> oh well I guess I'll just borrow one tonight
[18:00:06] <jdh> 3M 5200 is the best thing ever for boats
[18:00:40] <ssi> I'm gonna grab some 3m 1357 contact cement at spruce today
[18:00:43] <ssi> as well as some poly-tak
[18:01:07] <ssi> the 1357 is expensive, $40/qt, but by all accounts its the best contact cement on earth
[18:01:55] <jdh> that's a lot of contact cement. I have probably used 4oz in my life.
[18:02:14] <ssi> I'm spraying it, for upholstery
[18:03:01] <jdh> how long do you get before the nozzle clogs?
[18:03:38] <CaptHindsight> ssi: just talked to the #m rep he said they don't track inventory
[18:03:40] <ssi> we were spraying weldwood HHR yesterday, and it'll sit in the gun for hours without setting
[18:03:45] <CaptHindsight> you have to call the dealers
[18:04:01] <ssi> next day, it'd be solid, but it doesn't stick to the polypro cup and nozzle parts of that disposable tip 3m sprayer
[18:04:07] <ssi> so you can just pull the set glue out of it and reuse them
[18:05:04] -!- md-2 has quit [Quit: Leaving...]
[18:05:50] <CaptHindsight> just don't spray polypropylene adhesive
[18:05:56] <ssi> lol ya
[18:06:01] <ssi> did the embroidery yesterday too
[18:06:02] <ssi> https://scontent-a-atl.xx.fbcdn.net/hphotos-xap1/v/t1.0-9/9766_10100520524791652_4657380844245345821_n.jpg?oh=c70992eaa2662bc8482777750adb367a&oe=54E650DD
[18:06:15] <ssi> although now I'm second guessing myself on the placement
[18:09:03] <jthornton> looking good
