[00:25:12] <malcom2073> So friends wife asks me "Well... what will you use this mill for?" I couldn't answer her. She doesn't understand "brackets for other machines" or "cool stuff!". What do you all tell people who don't even know what a mill *is*, if they ask?
[00:25:31] <_methods> machine guns?
[00:25:45] <malcom2073> Haha I told her I would be machining an AR15 lower
[00:26:05] <archivist> I often have something I have made in a pocket
[00:26:06] <_methods> hehe
[00:26:20] <malcom2073> I've not made anything yet heh
[00:26:41] <Tom_itx> tell them you make things that make the world go round
[00:27:15] <Tom_itx> and that you are expanding your knowledge
[00:27:29] <malcom2073> She really wanted a concrete example that she could understand, of what it could actually do by way of an example
[00:27:31] -!- anth0ny has quit [Quit: anth0ny]
[00:27:51] <malcom2073> She didn't know what a mill was, I had to explain it was like a drill, but could cut sideways
[00:27:53] <syyl_> make her something
[00:27:59] <syyl_> and let her watch
[00:28:14] <syyl_> i did that with my girlfriend and we both hat great fun
[00:28:19] <malcom2073> syyl_: I plan on it, she wants a batman symbol cutout of 1/4" aluminum
[00:28:25] <malcom2073> but that's very... easy
[00:28:33] <malcom2073> NOt a really good example of what milling does
[00:29:05] <syyl_> https://dl.dropboxusercontent.com/u/24396704/pro_ring_damast_15.JPG
[00:29:15] <syyl_> i did the left ring while she was in the shop
[00:30:43] <Rab> malcom2073, make it a contoured relief.
[00:31:23] <malcom2073> Rab: She wanted a cutout, but I expect once I do that she'll want more hah

[01:42:57] <PetefromTn_> hey tom howsitgoin
[01:47:36] amnesic_away is now known as amnesic
[01:50:26] <PetefromTn_> Well I managed to sell a bunch of different items on the fleabay and picked up some cash from the part time job I have been working at so I can maybe start purchasing items for the CNC lathe build.
[01:51:34] <PetefromTn_> I am trying to decide what parts I want to get first. I kinda want to get the spindle motor and the ballscrew ordered so I can maybe actually use the lathe sorta manually while I get the control working. maybe...LOL
[01:53:21] <zeeshan|2> what kind of ball screws are you thinking of getting
[01:53:50] <PetefromTn_> probably can only afford ones from LInearmotionbearings..
[01:53:58] <PetefromTn_> this screw is rather large..
[01:54:09] <PetefromTn_> I just need the Z screw
[01:54:15] <zeeshan|2> diameter?
[01:54:46] amnesic is now known as amnesic_away
[01:55:27] <PetefromTn_> Well the largest he sells is 32mm I think
[01:56:33] <PetefromTn_> 1pc 3205-1600mm ballscrew with a double zero backlash ballnuts and end machined as both ends this is what he offered me for the specs I sent him Price was like $200.00 shipped
[02:01:05] <Tom_itx> just doing a bit of rewiring here
[02:01:15] <PetefromTn_> I should be able to find a suitable motor and get the ballscrew and possibly order some of the PC supplies with the cash I have the rest will have to wait until I can get a bit more cash or my tax return...

[02:38:06] <PetefromTn_> http://www.driveswarehouse.com/p-2534-wj200-037lf.aspx nice hitachi makes a single phase input sensorless vector drive for 5hp.. reasonable price. If I did go with a 5hp on the lathe it would probably save me about $500.00 or more... Depending on the motor I get.
[02:45:47] -!- patrickarlt has quit [Remote host closed the connection]
[02:48:11] <skunkworks> what is the spindle motor currently?
[02:49:14] <PetefromTn_> currently there is no spindle motor. but it came with a C frame type 7.5hp spindle motor as as option with a 5hp C frame type motor as standard equipment
[02:51:33] -!- micges has quit [Quit: Wychodzi]
[02:56:26] <zeeshan|2> thats rated for 3 ph input

[03:10:24] <bobo_> PetefromTn what would you guess $ differance of 5 HP vfd 1 vers 3 phase input to be .
[03:11:13] <PetefromTn_> well for the name brands like Hitachi it is about $300.00 difference or so.
[03:12:19] <PetefromTn_> http://www.driveswarehouse.com/p-2536-wj200-075lf.aspx This drive would probably work for a single phase input running 5hp motor. even tho it is 3 phase.
[03:13:00] <PetefromTn_> http://www.driveswarehouse.com/p-2123-pc1-50.aspx this is single phase 5hp input
[03:13:00] <bobo_> interesting thanks
[03:13:47] <PetefromTn_> http://www.ebay.com/itm/181559186612?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT then there is the one Zeeshan is using which has single phase input up to 5hp
[03:14:44] <PetefromTn_> There are also quite a few newer Chinese offerings on ebay that will run 5hp motors on single phase input.
[03:14:45] -!- skorasaurus has quit [Ping timeout: 252 seconds]
[03:17:04] <PetefromTn_> I have been kinda leaving it up to the motor I find for the best prices. IF I happen to find a 7.5hp motor that fits my machines specs for a great price I will grab it and get the appropriate vfd but if I happen upon a great deal on a 5hp I will just grab that and try to probably get another Hitachi or Teco vfd.
[03:18:40] <bobo_> was looking at www.dialog5.com -Wessler's project , where (I think ) he used external cap bank to get around #phase input limit
[03:19:23] <bobo_> Wessley's project
[03:20:18] -!- patrickarlt has quit [Quit: Leaving...]
[03:20:37] <PetefromTn_> not sure what you mean. My Cincinatti Arrow 500 has a 10hp motor and I run it on single phase input daily...
[03:21:24] <bobo_> also used a pre-charge circuit for inrush limiting
[03:22:50] <Tom_itx> mmm new spindle encoder is working
[03:22:58] <Tom_itx> need to figure out the index pulse
[03:23:21] <PetefromTn_> Tom_itx Nice man. What did you change on the encodr?
[03:23:40] <Tom_itx> went from a 48 count to a 2000 count with index
[03:24:02] <PetefromTn_> is it an off the shelf encoder or something you built from scratch?
[03:24:18] <Tom_itx> off the ... used equipment
[03:24:54] <Tom_itx> pretty small
[03:25:02] <Tom_itx> but just right for the mill
[03:25:13] <PetefromTn_> what did you need the additional counts for? or just the index
[03:25:17] <bobo_> just thinking if 3phase only was cheep vers pricer 1 phase than might be something to consider
[03:25:31] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/cnc/new_pulleys/spindle_enc6.jpg
[03:25:52] <PetefromTn_> the larger 3 phase input drives can be used you just need to double the size compared to the motor usually..
[03:25:54] <Tom_itx> i was after the index mostly but added res won't hurt anything
[03:26:39] <PetefromTn_> sure
[03:26:49] <PetefromTn_> you going to try rigid tapping with it or something?
[03:27:29] <Tom_itx> never can tell :)
[03:27:50] <PetefromTn_> heh
[03:39:02] <bobo_> Pete was wondering what the AC inrush amps are on the Cincinatti are at inital turn on
[03:39:37] <PetefromTn_> no idea but I run the entire machine on a 60 amp breaker and have never popped it yet
[03:41:53] <PetefromTn_> and actually ran a 1/2 inch endmill recently full depth thru 3/4 inch 6061 plate on accident and it slowed it down a touch but it never stopped... Scared the shit out of me hehe... that was at 4500 RPM and about 30 IPM... I cut the stock to the wrong length in my program and the cutter should have been just taking a little off the end hehe
[03:42:54] <bobo_> Chips bruse the paint?
[03:43:26] <PetefromTn_> what paint?
[03:44:03] <bobo_> paint inside machine
[03:44:28] <PetefromTn_> naah I got lucky with this machine the paint in the entire enclosure is in great shape.
[03:45:20] <bobo_> need bigger dof.
[03:45:52] <PetefromTn_> when I got it there was a TON of gunky stuck on coolant and chips glued all over it even on the outside but some good degreaser took care of that and now it looks really good inside and out.
[03:46:01] <PetefromTn_> dof?
[03:49:41] <bobo_> deeper depth of feed -----some people aren't happy unless chips are chiping paint off the bosses mach
[03:50:56] <PetefromTn_> Oh depth of cut. yeah I think that was PLENTY deep LOL. It was supposed to be a sort of full depth peel milling around the outside of the material working its way in until it leaved a finish pass of .01 of the actual part.
[03:58:03] <bobo_> Pete did you get a chcnce to look at the watch outide ring the garage journal guy was asking for quotes on ?
[04:00:06] <bobo_> have heard that watch is of 304 stainless material
[04:00:45] <PetefromTn_> no not really I was not aware he was wanting quotes. I thought you just wanted me to see what he was making. Besides I doubt I would be competitively priced for a one off part like that in stainless

[06:03:27] <evilren> haha.making sure that slacker daddy still working, keeping her breakfast cereal jar filled, and new designer booty pajamas
[06:13:54] <PetefromTn_> yeah man she is awesome.
[06:14:15] <PetefromTn_> she is always asking me how it is going in the shop and what kind of cool parts I am going to make next
[06:14:40] <PetefromTn_> I have been trying to come up with something new and interesting for my personal sales here lately
[06:15:28] <PetefromTn_> I have been watching a lot of youtube vids of other guys who make stuff for sale guys like John Grimsmo and some others. They make some neat stuff and have some cool ideas
[06:15:59] <PetefromTn_> I don't exactly want to get into making knives but some of the stuff they do can be applied to other projects.
[06:16:38] <PetefromTn_> My program for the Picatinny rail profile works awesome and I have run it a bunch of times so I know it works. I have been thinking of some new applications for it.
[06:17:35] <PetefromTn_> any of you guys tried crazy glue to hold down metal parts for light milling?
[06:17:50] <PetefromTn_> and engraving etc.
[06:18:13] <evilren> ive used double sided sticky tape
[06:18:27] <PetefromTn_> yeah I have done that a bunch
[06:18:30] <evilren> vhb type stuff but not as hardcore
[06:18:33] <PetefromTn_> it actually works quite well
[06:18:45] <toastydeath> I used to know a guy who held down large parts with stickey tape
[06:18:45] <PetefromTn_> but I have not really tried it with coolant flowing
[06:18:49] <toastydeath> on a 50" VBM
[06:19:00] <toastydeath> sheet metal
[06:19:21] <PetefromTn_> just watched a vid where john G held down some beautiful copper parts with crazy glue
[06:19:33] <PetefromTn_> seemed to work well altho one edge did lift up on him on the go around
[06:19:43] <evilren> ca glue comes in a ton of varieties
[06:19:47] <PetefromTn_> Copper is really sticky to machine so not terribly surprised by that
[06:20:21] <evilren> cleans up easy with acetone
[06:20:50] <PetefromTn_> that Intake manifold cover I designed they are trying to figure out how many they want and I have been trying to determine ways to speed up the process and hold it down tightly without clamping and unclamping
[06:21:30] <PetefromTn_> if they order enough of them I will probably buy a little vacuum pump or maybe even a venturi vaccum block and make a fixture to mill five or six at a time
[06:21:33] -!- Tecan has quit [Quit: Live Long And Phosphor!]
[06:22:03] <PetefromTn_> that would allow me to do some other things to it that were more difficult the way I made the prototype
[06:26:25] <roycroft> i made a venturi vacuum pump a few years ago for doing wood veneer
[06:26:37] -!- Komzpa has quit [Ping timeout: 272 seconds]
[06:26:38] <roycroft> it works great
[06:26:55] <PetefromTn_> nice... does the compressor run like freakin' crazy or is it not too bad
[06:27:04] <PetefromTn_> I know Horrible Freight sells one for a reasonable price
[06:27:12] <PetefromTn_> I had considered getting one of those
[06:27:18] <roycroft> i use one of those 3 gallon portable air tanks as a vacuum reservoir
[06:27:28] <roycroft> and that helps keep the compressor from running non-stop
[06:27:40] <PetefromTn_> no kidding I have one of those here.
[06:27:42] <Jymmm> PetefromTn_: Dude, Make your girl something for no reason at all this week.
[06:27:57] <roycroft> if your seals are good it doesn't have to run constantly
[06:28:11] <PetefromTn_> my compresor is a vertical 220v model from Lowes it is not great but it works really well.
[06:28:14] <roycroft> and vacuum clamping is incredibly strong
[06:28:21] <PetefromTn_> Jymmm yeah man I need to.
[06:28:34] <roycroft> i have a 5hp compressor from home depot
[06:28:46] <PetefromTn_> yeah these LIM covers I am making will be a perfect project for vacuum hold down..
[06:28:48] <roycroft> about 10 years ago the motor died and i bought a leeson to replace it
[06:29:07] <PetefromTn_> There is a lot of surface area to clamp to and only a few thru holes on the perimeter
[06:29:20] <Jymmm> PetefromTn_: GIVE IT TO HER THIS WEEK, no slacking off now. she don't care what it is, expect it's from Daddy to her. Make a small necklace charm, or something
[06:30:01] <roycroft> about 4 years ago the compressor itself died and i replaced it with a us-made one (i forget the brand right offhand, but it was made in wisconsin)
[06:30:06] <Jymmm> PetefromTn_: it could be her monogram even
[06:30:09] <PetefromTn_> I hear ya LOL.... Believe me I spend a LOT of time with my kids especially since I am at home working instead of out working for someone else. It really is nice.
[06:30:10] <roycroft> it's a really nice compressor now
[06:31:14] <PetefromTn_> If I can get my shop into a good position with the new CNC lathe and the mill making more money I will be very happy guy and be able to take care of my kids and do their homework etc etc like I have been.
[06:32:35] <PetefromTn_> It is kind of a dream of mine to be able to work for myself at home making cool parts and be able to be with my family all the time. It is just not easy to get the work going and the retrofit has taken a lot of time. Hopefully the Lathe will be a bit simpler and be going a bit quicker
[06:33:08] <roycroft> i've never been happy working for other people
[06:33:19] <roycroft> i was self-employed for a long time, and would like to be again
[06:33:32] <PetefromTn_> maybe I will run down to HF and grab that venturi vaccum pump they sell.
[06:33:47] <PetefromTn_> I have wanted to try a vacuum hold down fixture on the mill for awhile.
[06:34:15] <roycroft> i got mine from a veneer supply outfit, but it's similar to the hf one
[06:34:18] <PetefromTn_> with the Kurt D688 it has an 8.8" opening and then you can swap the jaws to the outside and hold quite a large fixture without having to remove the vise
[06:34:52] <PetefromTn_> the Custom Battery trays I make for the race shop guys is all done on a vise mounted fixture.
[06:36:03] <roycroft> you can't make money doing production work without good jigs/fixtures
[06:36:18] <PetefromTn_> fer sure
[06:36:49] <PetefromTn_> so far I have a bunch of custom fixtures out in the shop and I have just gotten started in this stuff.
[06:40:05] <roycroft> i've only done a handful of paid jobs machining - my work is almost entirely personal projects and learning projects, but i used to make custom cabinets a long time ago
[06:40:21] <roycroft> it's the exact same way with woodworking - jigs and fixtures make or break you
[06:40:53] <PetefromTn_> hehe you don't have to tell me man I was a professional Custom Cabinet builder/designer for almost 20 years!
[06:41:53] <PetefromTn_> built countless kitchen,bathroom,built ins, and custom cabinets in multi million dollar homes out of every style and material you can imagine
[06:42:33] <roycroft> that world is too competetive now
[06:42:38] <bobo_> so--the kids homework just how is old dad doing with that NEW math stuff confused with that NEW history stuff yet ?
[06:43:34] <roycroft> www.roycroft.us/NewMath.mp3
[06:43:42] <roycroft> speaking of which :)
[06:44:20] <PetefromTn_> honestly I took a lot of pride in my custom cabinet work and I could probably go right back to it with paying customers in no time as I have a bunch of people always asking me if I still make cabinets heh
[06:45:06] <PetefromTn_> there are still a couple very loyal customers who I would drop what I am doing for and make a kitchen or bathroom just because they were so good to work with before.
[06:45:21] <roycroft> i'm getting a bit old to be hauling sheet goods around all day
[06:45:26] <PetefromTn_> I still have enough woodworking equipment to do most stuff.
[06:45:34] <roycroft> it's funny
[06:45:51] <roycroft> metal is heavier, well, more dense, than wood
[06:45:53] <PetefromTn_> my biggest reason for NOT doing it anymore is that it takes a lot of room to build a kitchen full of cabinets and my shop is not that big
[06:46:06] <roycroft> but we usually use smaller bits of it at a time, or have devics to help move it around
[06:46:29] <roycroft> well it doesn't take that much room to build a kitchen full of cabinets
[06:46:34] <PetefromTn_> that and after having lung surgery it is probably not the best idea for me to be sucking up a bunch of sawdust...
[06:46:38] <roycroft> but it takes a lot of room to store them until they're all done :)
[06:47:06] <PetefromTn_> yeah I have built a ton of kitchens from my shop and once they are assembled it gets REAL cramped real fast
[06:47:45] <roycroft> my shop would have plenty of room if it weren't for all the materials and projects
[06:47:46] <PetefromTn_> the last one I did I did like I typically do and stash some of them in the house in the den but even that was not enough room
[06:48:33] <PetefromTn_> plus finishing gets real tedious and I seem to always forget a piece of trim or something and have to revert back to woodworking mode and that creates its own problems
[06:48:50] <PetefromTn_> you really need a shop about twice the size of mine at least to be able to do it right.
[06:49:14] <PetefromTn_> The metalworking is MUCH cleaner, quieter, and takes up a helluva lot less room overall.
[06:49:34] <roycroft> and you don't have to go out to cold, wet, muddy job sites all the time
[06:49:48] <PetefromTn_> my next door neighbor who is a very nice Italian lady came over the other day and wanted me to make some wood circles from some plywood for her
[06:50:31] <PetefromTn_> I made them in like fifteen minutes and she asked me if I was not able to find cabinet jobs because she had not heard any saws running lately LOL
[06:50:53] <roycroft> my main shop is my garage
[06:50:55] <PetefromTn_> I told her that I am making metal parts now and showed her the CNC machines and some parts I was working on
[06:51:09] <roycroft> which is my machine shop, woodworking shop, brewhouse, and laundry room
[06:51:17] <PetefromTn_> she was like Oh thats nice but you were so good at woodworking LOL...
[06:51:23] <roycroft> it's kind of a pain because sawdust and metal chips don't mix very well
[06:51:31] <PetefromTn_> that is pretty much how my shop is too..
[06:51:38] <roycroft> all my machinery has covers
[06:52:02] <roycroft> and i just have to do a big cleanup whenever i switch modes from woodworking to machining and vice versa
[06:52:23] <roycroft> i do have an outbuilding that i use for welding/grinding
[06:52:32] <roycroft> so i keep that grinding dust out of the main shop
[06:56:23] <roycroft> i don't have anything resembling a paint booth
[06:56:35] <roycroft> when i have to do a lot of painting i move the machinery out of half the garage
[06:56:37] <Jymmm> Whats that word that reports use to say something about someone but no actually accuse them of it, begins with an "a"?
[06:56:42] <roycroft> then i put up a tent frame in the other half
[06:56:46] <Jymmm> reporters*
[06:56:54] <roycroft> alledge?
[06:57:01] <Jymmm> not apprantntly, but something like it
[06:57:14] <Jymmm> YES! TY roycroft
[06:57:20] <PetefromTn_> alledged
[06:57:31] <roycroft> then i hang a "tent" that i made out of 6mil plastic and duct tape from the frame
[06:57:42] <roycroft> it has a taped-on zipper for a door
[06:57:58] <PetefromTn_> LOL I actually made a big PVC pipe paint booth I used to assemble outside the shop
[06:58:27] <roycroft> i set that up, line it with bricks around the permeter to keep the walls from collapsing in, then spray the walls and floor down with water, set up a table, and start painting

[18:04:46] <mozmck> I've been going through JT-Shop's gui tutorial (very nice tutorial btw!), and he has a homing_ok() function which returns false if the axis is already homed.
[18:04:56] <pcw_home> axis belly-aches about it but allows it
[18:06:33] <mozmck> huh, ok. for some machines it is not uncommon to need to re-home - say after a crash or e-stop where position might be lost.

[19:14:53] <zeeshan|2> god i hate this stupid sumitomo vfd's modbus control

[19:15:38] <zeeshan|2> theyre using their own communication system

[19:21:46] <zeeshan|2> how do i put this
[19:22:00] <zeeshan|2> modbus is a standard protocol right..
[19:22:00] <skunkworks> does it have analog input?
[19:22:10] <zeeshan|2> skunkworks: yea
[19:22:16] <zeeshan|2> but i want to communicate over rs485
[19:22:17] <skunkworks> well there you go :)

[19:22:29] -!- pjm_ has quit [Quit: KVIrc 4.2.0 Equilibrium http://www.kvirc.net/]
[19:22:45] <zeeshan|2> in regular modbus you can do something like "read_input_registers" which is a standard function with a function code of 04
[19:22:53] -!- pjm [pjm!~pjm@uhfsatcom.plus.com] has joined #linuxcnc
[19:22:54] <zeeshan|2> and then you specify the address, and the number of registers you want to read
[19:23:11] <zeeshan|2> and if youre using ascii mode , it does a LRC check , or if its RTU mode it does a crc check
[19:23:17] pjm is now known as Guest19679
[19:23:22] <zeeshan|2> these guys decided to change the function codes to random ones

[19:24:42] <zeeshan|2> cat > /dev/ttys0 & echo -e "231902138091238092130982132"
[19:24:52] <zeeshan|2> anyone know how i can transmit in ASCII
[19:24:54] <cpresser> zeeshan|2: with minimalmodbus you can do 'instrument.read_register(register=0815, functioncode=0xaffe)'
[19:25:15] <zeeshan|2> cpresser: will it do a BCC check?
[19:25:25] * cpresser recommends to start a python shell and try this
[19:25:26] <zeeshan|2> bcc check is basically XOR all the ascii code
[19:25:33] <cpresser> BCC = checksum?
[19:25:35] <zeeshan|2> yes
[19:25:39] <cpresser> yes, it does
[19:26:51] <cpresser> non-standart modbus sucks. i had some trouble with a 'burster9180' amplifier. i will write a (negative) review on by blog
[19:31:18] <zeeshan|2> hehe
[19:37:18] <zeeshan|2> okay minimalmodbus seems to be working with the standard modbus vfds

[19:53:49] <zeeshan|2> this library is REALLY good
[19:53:53] <PetefromTn_> I could use some help with it tho if you guys have the time. I was thinking I could post a lot of screen shots and photos and whatnot and try to get the config that currently works saved.

[20:07:32] <Computer_Barf> anyone know of any intel atom alternatives for small pc's for linux cnc?
[20:07:59] <Computer_Barf> Ive considered using a beaglebone black with a mesa ethernet card
[20:11:02] <skunkworks> does the beaglebone have dedicated ethernet?
[20:11:08] <malcom2073> I use a beaglebone black without a mesa ethernet card :P
[20:11:10] <PetefromTn_> dunno man but I am getting ready to start my CNC lathe retrofit and will probably pickup the J1900 board as recommended by PCW recently. MY Cinci uses the atom D525 board but do have some issues with the occasional real time error.
[20:13:11] <skunkworks> as malcom2073 says - the bbb does have its own built in hardware stepgen/pwmgen/encoder counter (pru)
[20:13:46] <zeeshan|2> how many enconder counts?
[20:14:31] <Computer_Barf> yeah , I had a few diffrent reasons for the mesa card, and encoders was part of that

[20:23:46] <Computer_Barf> ive been considering this because ive heard its got good latency for linuxcnc,
[20:24:33] <Computer_Barf> but i mean, im surprised were not seeing custom atom boards
[20:30:11] <SpeedEvil> what do you mean?
[20:31:29] <Computer_Barf> i mean stuff with onboard ram, storage, stripped of all the stuff you wouldn't really need for cnc. More stuff like minnowboard max
[20:32:12] <Computer_Barf> maybe gpio , beaglebone black like all in one boards that are pc's intended for cnc application

[20:34:46] <CaptHindsight> plus there's not that much volume in making x86 mainboards for Linuxcnc
[20:35:23] <Computer_Barf> ahh yes, I shouldn't ignore the economics
[20:36:49] <CaptHindsight> and what would an x86 mainboard for Linuxcnc have that a standard mini-itz or atx would not?
[20:37:01] <malcom2073> It'd have a mesa built in!
[20:37:02] <malcom2073> :-D
[20:37:05] <CaptHindsight> maybe lack of EPP for AMD boards
[20:37:34] <Computer_Barf> well, take a look at the minnowboard max
http://www.minnowboard.org/meet-minnowboard-max/
[20:37:43] <Computer_Barf> pretty stripped down
[20:38:37] <Computer_Barf> still an atom processor, still an ethernet port for the 7i76e mesa board
[20:39:08] <Computer_Barf> but malcom2073 had a good point, having the mesa be part of it.
[20:39:41] <CaptHindsight> site won't even load for me :(
[20:39:48] <Computer_Barf> :(
[20:40:12] <malcom2073> Some of these boards have PCI-E, are there any PCI-E mesa's, or only PCI?
[20:40:25] <CaptHindsight> pci and pcie
[20:40:42] <Computer_Barf> mesa 7i76e , with the e standing for ethernet
[20:41:49] <CaptHindsight> http://elinux.org/Minnowboard:MinnowMax
[20:42:14] tjb11 is now known as tjb1
[20:42:34] <CaptHindsight> someone could make an x86 board with a xilinx fpga but then you have the pinout issues
[20:42:54] <CaptHindsight> which version of IO boards do you support the 50 pin or?
[20:44:03] <Computer_Barf> the minowboard max looks nice but, its like 160 ish when im looking for 99.99 ish
[20:44:33] <CaptHindsight> and it would need the largest fpga to cover the range of IO people use from what EPP can handle to 8 axis servo
[20:45:31] <CaptHindsight> is that the Atom without a GPU?
[20:46:03] <CaptHindsight> no it has one
[20:46:33] <Computer_Barf> i could get the beaglebone black and hook the 7i76e to the ethernet but im worried that the beaglebone black might lag too much
[20:47:12] <Computer_Barf> ill probably play it safe and buy a biostar mini atx
[20:47:34] <malcom2073> the BBB lags hardcore when doing UI stuff, it's nice as a headless controller though
[20:48:43] <Computer_Barf> yeah, thats what i figured
[20:49:23] <malcom2073> I'm sticking with atom boards on any machine I can fit it on heh
[20:49:24] <CaptHindsight> try one of the allwineer or imx6 boards with ethernet and GPU

[22:09:29] <PetefromTn_> Okay folks.. I just fired up the Cincinatti and I am going to TRY to get this thing converted to Imperial native units. I am going to try to work thru it starting with saving the current configuration to my flash drive. I am going to setup my laptop out in the shop so I can work between the two machines and be able to post pictures etc. if I need any help. Hoping I can get some assistance when I invariably get stuck.
[22:09:44] <PetefromTn_> machine is almost finished warming up.
[22:10:07] <cradek> is this linuxcnc and you're just editing a config?
[22:11:02] <PetefromTn_> yes this is linuxCNC and I want to edit my original configuration on the Cincinatti Arrow 500 from a metric native units to an imperial Native units so I can get my tool table editor to reflect Imperial dimensions.

[22:11:55] <PetefromTn_> yeah I know but as you may or may not know I am not good at this stuff and I will not have help other than you guys on here today.

[22:12:35] <PetefromTn_> It is apparently more than just changing some simple quick settings the servo tuning parameters are also involved and would need to be changed.
[22:12:46] <cradek> do you know how many mm there are in an inch?
[22:12:53] <PetefromTn_> Hopefully without screwing up the whole damn machine as it works really good right now..

[22:13:02] <cradek> then you're set :-)
[22:13:03] <PetefromTn_> I work back and forth all the time
[22:13:26] <cradek> hmm I am not sure if you'll have to change pid parameters
[22:13:32] <PetefromTn_> but I am very used to the HAAS machines at my other places of work that all use inch dimensions for cutter compensation and tool settings
[22:13:50] <PetefromTn_> honestly I am quite open to any suggestions you may have
[22:13:56] <cradek> if your tooling is mostly inch sized, then having a mm tooltable would suck
[22:14:20] <PetefromTn_> I just want the machine to operate the way it currently does but allow me to use inch measurements and tool offsets.
[22:14:28] <PetefromTn_> yes indeed it definitely does SUCK right now.
[22:14:49] <PetefromTn_> and I am trying to integrate cutter compensation into my CAM program with the machines post to allow me to make changes at the machine.
[22:14:56] <PetefromTn_> This is QUITE important to me right now
[22:15:29] <cradek> at first glance I bet P,I,D will need to get scaled but FF1,FF2 won't
[22:15:36] <PetefromTn_> The way the machine works right now it is setup to boot directly into linuxCNC upon startup...
[22:16:37] <PetefromTn_> which I would assume is NOT an issue because you just minimize the linuxCNC axis control interface and get to the ububtu desktop and I can then save the configuration file to the flash drive. I think I did this before correctly but not sure what if anything I may have missed.
[22:17:01] <cradek> I bet if P is 1000 in mm, it'll be 39.37 in inches because it's multiplied by the amount of error
[22:17:04] <PetefromTn_> I realize this is all very simple stuff to you guys but to me it is not and I do not want to screw up the working running machine..
[22:17:13] <cradek> same for I,D
[22:17:23] <cradek> you'll want to save the whole config directory
[22:17:40] <PetefromTn_> Let me get setup out there with the laptop and I can get started here. Hopefully it will not take long..
[22:17:51] <cradek> I have to run, but I bet lots of folks here can help

[22:51:03] <rob_h> even the new controls too
[22:51:06] <PetefromTn_> Ok so I have the entire linuxCNC folder saved to the flash drive now with the exception of the examples stuff
[22:51:16] <rob_h> ok
[22:51:26] <rob_h> so now you can make the changed needed
[22:51:32] <PetefromTn_> I am going to remove the flash drive and stick it in the laptop here and then I will post my hal and ini files to pastebin
[22:51:34] <rob_h> if something does not work you can now reff back to the old stuff
[22:51:41] <rob_h> ok
[22:52:24] <rob_h> did you ever get your ATC working peter?
[22:52:46] <PetefromTn_> no not yet still need spindle orient to work
[22:53:04] <rob_h> oh did you chagne the drive
[22:53:07] <karl> yeah i've tried inverting the polarity too, but no change. I don't know if this matters, but i don't get the error if i only set the switches to be homing and no limit - however, the homing still doesn't work - the switch get tripped but the machine just keeps going, eventually hitting the rails
[22:53:50] <PetefromTn_> http://pastebin.com/cm26eGLt
[22:54:40] <rob_h> is it a one switch does both?
[22:54:42] <PetefromTn_> http://pastebin.com/49eM9Ukn
[22:54:44] <rob_h> ie home and limit
[22:54:55] <PetefromTn_> no the machine has seperate homes and limits
[22:55:11] <rob_h> sorry i talkign to karl peter
[22:55:16] <rob_h> erm both links same
[22:55:24] <karl> i have one switch per axis, those switches will be configured as both homing/limit for that axis
[22:55:29] <PetefromTn_> the spindle drive as well as the rest of the electronics with the exception of the spindle motor is all brand new
[22:55:56] <rob_h> aah yea makes it fun to setup orient then been there done that
[22:56:06] <PetefromTn_> oops sorry
[22:56:53] <rob_h> also does the ini end like pastbin says... at spindle, output_max_limit
[22:56:54] <PetefromTn_> http://pastebin.com/UqM9zze5

[22:58:28] <rob_h> karl sorry cant help much more iv not tryed to setup a switch like that where its a home and limit maybe someone else will help soon
[22:59:13] <PetefromTn_> it looks that way last line on the machines file reads OUTPUT_MAX_LIMIT = 6000
[23:01:07] <rob_h> ok, just checking was all
[23:01:15] <PetefromTn_> is that not normal?
[23:01:47] <rob_h> its fine
[23:01:50] <PetefromTn_> my spindle drive is the Hitachi WJ200-110LF and we have it actually configured via modbus
[23:01:52] <rob_h> just depends how your ini was made
[23:01:57] <PetefromTn_> it will rigid tap now perfectly
[23:02:11] <rob_h> in closed vector
[23:02:16] <PetefromTn_> we made the whole setup initially with PncConf and then modified from there
[23:02:36] <karl> thanks anyway. tho even getting them to work as homing switches alone would be great, not sure why it doesn't go with the latch velocity when it hits the switch
[23:02:55] <PetefromTn_> the toolchanger is the next big step and right now I want to concentrate on the Imperial measurements
[23:03:37] <PetefromTn_> There is a fellow named Brendon in New Zealand I have been trying to help convert the same exact machine and he will probably be able to use some of what I have setup on my machine hopefully.
[23:03:42] <rob_h> Karl, manual is quite good on that just double check it... is multi setups to homing i know
[23:04:07] <rob_h> yea they are all quite the same
[23:04:24] <rob_h> i had to replace my spindle drive not long after conversion, it was a mitsubishi tho
[23:04:30] <rob_h> crazy price to have it fixed
[23:05:01] -!- The_Ball [The_Ball!~ballen@202.10.92.134] has joined #linuxcnc
[23:05:02] <rob_h> altho it did kinda work in closed vector for orientation etc.. it was never as good
[23:05:07] <PetefromTn_> yeah my spindle drive was an emerson Control techniques Spindaxx 200 and good lord are those things expensive...
[23:05:18] <rob_h> now i have a yaskawa on it.. but with there spindle software on the drive.. and it works grate
[23:05:44] <PetefromTn_> I thought you said you had mechanical orient or something like that.
[23:05:49] <PetefromTn_> perhaps it was someone else
[23:05:52] <rob_h> yea emerson dont have anything todo with CNC any more.. and they get lost when you talk CNC now days
[23:06:20] -!- R2E4_ has quit [Read error: No route to host]
[23:06:21] <PetefromTn_> actually from what I understand they do make controls now and they are quite advanced....cannot remember the name
[23:06:53] <PetefromTn_> so anyways back to the conversion to imperial
[23:07:09] <rob_h> back in the days...
https://www.youtube.com/watch?v=D6dGYsXAPIU
[23:07:09] <PetefromTn_> I have backed up the files to the laptop
[23:07:14] <rob_h> yes
[23:07:19] <rob_h> looked over the hal
[23:07:25] <rob_h> looks grate, all need to tweak is the ini
[23:07:39] <PetefromTn_> you are the one who made that vid LOL nice man I see it worked okay at least..
[23:07:46] <PetefromTn_> are you sure of that>
[23:07:50] <rob_h> where it says, Axis X , axis y, axis z

[23:08:29] <rob_h> you need to convert some things to imperal like encoder_scale

[23:08:54] <rob_h> under traj .. linear_units = mm becomes. ...
[23:09:09] <PetefromTn_> okay so I need to shut down the currently running linuxCNC program
[23:09:17] <rob_h> yea if its running
[23:09:41] <PetefromTn_> I am going to put it in estop and shut down the program but keep the PC with ubunut live
[23:09:46] -!- R2E4_ [R2E4_!~IceChat9@207.164.206.172] has joined #linuxcnc
[23:10:02] <rob_h> yep
[23:10:21] <PetefromTn_> once the changes are made restarting the entire machine will be necessary unfortunatley this way but it is the safest I think
[23:10:34] <rob_h> DEFAULT_VELOCITY = 20
[23:10:35] <rob_h> MAX_LINEAR_VELOCITY = 266.66667 need converting too in [TRAJ]
[23:12:00] <rob_h> or just loadup the machine from the menu or shortcut
[23:12:05] <PetefromTn_> Okay so one thing at a time here. for each axis I need to change the encoder scale from 1250 by divide by 25.4?
[23:12:08] <rob_h> dont need to reboot
[23:12:43] <PetefromTn_> perhaps it would be easiest to start at the top of the .ini file..
[23:12:44] <rob_h> your looking for anything that is in machine units..
[23:12:49] <rob_h> ye
[23:13:13] <PetefromTn_> max feed override spindle override are set to 2.0000
[23:13:32] <PetefromTn_> that is just 200 percent right
[23:14:23] <rob_h> ye they are % so are fine
[23:14:39] <rob_h> under display
[23:14:40] <rob_h> DEFAULT_LINEAR_VELOCITY = 33.333
[23:14:40] <rob_h> MAX_LINEAR_VELOCITY = 133.66667
[23:14:40] <rob_h> MIN_LINEAR_VELOCITY = 0.010000
[23:14:40] <rob_h> DEFAULT_ANGULAR_VELOCITY = 0.250000
[23:14:40] <rob_h> MAX_ANGULAR_VELOCITY = 1.000000
[23:14:41] <PetefromTn_> def lin vel 33.333
[23:14:44] <rob_h> MIN_ANGULAR_VELOCITY = 0.010000
[23:15:51] <rob_h> only thing ill not be sure off as chris said.. is the PIDs iv never changed a machine over before
[23:16:56] <rob_h> but id just /25.4 and should be fine
[23:16:59] <PetefromTn_> so for instance the first one would be multiplied by 25.4 to is 846.6582 that does not sound right
[23:17:09] <rob_h> its in MM right now
[23:17:12] <rob_h> so need to make it "
[23:17:19] -!- karl has quit [Quit: Leaving]
[23:17:27] <PetefromTn_> 1.31?
[23:17:33] <rob_h> so 33.333 becomes 1.312
[23:17:53] <PetefromTn_> does that sound right for a default linear velocity?
[23:18:32] <rob_h> its what the machine is at on load/start
[23:18:34] <rob_h> on the slider
[23:18:36] -!- adb has quit [Ping timeout: 276 seconds]
[23:18:58] <rob_h> 2000mm
[23:19:01] <PetefromTn_> it is usually at like 75 IPM or something like taht
[23:19:02] <PetefromTn_> that
[23:19:04] <rob_h> so just makign it the same but in inch
[23:19:38] <PetefromTn_> okay so all of those settings you just noted divide by 25.4
[23:19:40] <rob_h> it is in seconds
[23:19:46] <rob_h> so *60 = per min
[23:19:57] <rob_h> its in the manual
[23:20:06] <rob_h> yep
[23:20:21] <rob_h> they just contorl sliders on the axis gui
[23:20:28] <PetefromTn_> so 1.312 is correct then
[23:20:49] <PetefromTn_> that would be 78.2 so that sounds correct
[23:21:00] <rob_h> ye
[23:21:01] <PetefromTn_> hang on I will make these changes
[23:21:03] <rob_h> can change it if u wish
[23:21:46] <PetefromTn_> what do you mean
[23:22:01] <rob_h> if you wanted some other default speed
[23:22:23] <rob_h> 50ipm instead or 100
[23:22:33] <PetefromTn_> like I said the machine is just fine right now the way it is I just want to get it to be native inch
[23:22:47] <rob_h> brb gunna grab a drink
[23:22:49] <PetefromTn_> then I can play with other settings once it is working the way I want
[23:22:51] <PetefromTn_> OK
[23:25:11] <Tom_itx> goin back to inch ehh?
[23:25:29] <PetefromTn_> trying to
[23:25:46] <PetefromTn_> should have known better then making it native metric
[23:25:53] <Tom_itx> heh
[23:26:14] <rob_h> you was getting ready for the switch over ;)
[23:26:15] <PetefromTn_> we just thought we could use Lee's configuration to get it going faster and he has the same machine
[23:26:15] Audioburn is now known as pinkfloyd
[23:26:16] <rob_h> [TRAJ]
[23:26:16] <rob_h> LINEAR_UNITS = mm
[23:26:16] <rob_h> DEFAULT_VELOCITY = 20
[23:26:16] <rob_h> MAX_LINEAR_VELOCITY = 266.66667
[23:26:25] <PetefromTn_> ok hang on
[23:26:39] <PetefromTn_> the default angular velocity is also converted?
[23:26:46] <PetefromTn_> as well as the max and min angular?
[23:26:47] <Tom_itx> they all get converted
[23:26:53] <rob_h> yea
[23:27:01] <Tom_itx> it's not the same units now
[23:27:02] pinkfloyd is now known as audioburn
[23:27:14] <rob_h> would make it pritty fast other wise
[23:27:23] <PetefromTn_> ok stby
[23:28:24] <Tom_itx> some you may need to read about to convert properly
[23:28:51] <PetefromTn_> Okay so I have
[23:29:07] <PetefromTn_> Defailt angular vel .00984251
[23:29:09] <rob_h> you have pritty big following errors
[23:29:23] <PetefromTn_> max ang .03937007874
[23:29:41] <PetefromTn_> min ang .00039370079
[23:29:59] <rob_h> sounds right i did not do the math my self
[23:30:02] <PetefromTn_> I am sure we just got it to work and did not mess with it I really need to do some more tuning and set them tighter
[23:30:14] <PetefromTn_> okay next item
[23:30:27] <rob_h> in the traj section
[23:30:38] <rob_h> [TRAJ]
[23:30:38] <rob_h> LINEAR_UNITS = mm
[23:30:38] <rob_h> DEFAULT_VELOCITY = 20
[23:30:38] <rob_h> MAX_LINEAR_VELOCITY = 266.66667
[23:30:38] <rob_h> becomes
[23:30:38] <rob_h> [TRAJ]
[23:30:40] <rob_h> LINEAR_UNITS = inch
[23:30:42] <rob_h> DEFAULT_VELOCITY = 0.787
[23:30:46] <rob_h> MAX_LINEAR_VELOCITY = 10.498687795275590551181102362205
[23:30:52] <rob_h> obvisly you can round that long one abit
[23:32:40] <PetefromTn_> OK so no force homing is still 1 and cycle time is still .010
[23:32:51] <rob_h> yea
[23:32:56] <rob_h> what i missed out just leave as is
[23:33:09] <PetefromTn_> K
[23:33:29] <cradek> angles (ABC axes) are always in degrees so you should not change them
[23:33:51] <PetefromTn_> does that include the angular velocities
[23:34:03] <cradek> yes, deg/sec deg/sec^2
[23:34:10] <PetefromTn_> shit
[23:35:04] <PetefromTn_> so default angular, max and min angular need to be changed back..
[23:36:18] <PetefromTn_> it was .25 .1 and .01
[23:36:33] <PetefromTn_> or rather 1.0
[23:36:36] <PetefromTn_> and .01
[23:36:41] <PetefromTn_> is this correct chris?
[23:36:48] -!- bedah has quit [Quit: Ex-Chat]
[23:36:56] <rob_h> yea sorry forgot about them

[23:36:59] <rob_h> MAX_ANGULAR_VELOCITY = 1.000000
[23:36:59] <rob_h> MIN_ANGULAR_VELOCITY = 0.010000
[23:37:05] <rob_h> thats what it should be
[23:37:59] <PetefromTn_> ok changed back
[23:38:18] <PetefromTn_> the traj settings are ok?
[23:38:25] <PetefromTn_> rather the changes we made
[23:38:45] <rob_h> ye
[23:38:57] <PetefromTn_> Ok axes now..
[23:40:03] <PetefromTn_> this is where it will get complicated I suppose
[23:40:26] <rob_h> just need to find machine units settings and change them over like you just did
[23:40:52] <PetefromTn_> I am not sure what they are completely
[23:41:10] <rob_h> the manual does show pritty well what is what..
http://linuxcnc.org/docs/html/config/ini_config.html#sub:AXIS-section
[23:41:22] <PetefromTn_> Home at 255 is 10.39
[23:41:39] <rob_h> 10.039
[23:41:51] <PetefromTn_> yeah sorry
[23:44:28] <zeeshan|2> PetefromTn_: just go through each variable
[23:44:44] <zeeshan|2> :-)
[23:45:25] <PetefromTn_> yeah but that scares the piss out of me man heh
[23:45:42] <Tom_itx> gotta start somewher
[23:45:43] <Tom_itx> e
[23:45:59] <Tom_itx> you got a backup config i'm sure
[23:46:18] <PetefromTn_> OK down to max velocity on X...
[23:46:34] <PetefromTn_> it was 300 changed to 11.8110236

[23:46:59] zeeshan|2 is now known as zeeshan
[23:47:17] <PetefromTn_> when we setup the machine it would do over 750 IPM but I have it knocked down to save my sanity
[23:47:57] <rob_h> i see Z is realy slow
[23:48:08] <PetefromTn_> yup same reasons
[23:48:10] <rob_h> 5m/min
[23:48:12] <LeelooMinai> I wonder why they use "per minute" for or those linear figures... It's much easier to get a sense how fast something is in "per second"
[23:48:19] <LeelooMinai> or=all
[23:48:36] <CaptHindsight> tradition
[23:48:44] <PetefromTn_> what do you think of the PID and FF1 settings..
[23:48:55] <LeelooMinai> I mean "per minute" is good for snail not a machine:)
[23:49:09] <cradek> tradition! but originally, maybe so you can use integers

[23:49:30] <CaptHindsight> lots of rates are at a snails pace
[23:49:39] <LeelooMinai> Wel, mm/s would use integers too
[23:49:52] <zeeshan> today my professor whos a "leading expert" in machining
[23:49:57] <CaptHindsight> think 1932
[23:50:09] <zeeshan> is like the best method is tue take your grinding wheel
[23:50:13] <PetefromTn_> no idea what to do with the PID and FF1 settings but max outputand encoder scale needs to stay the same right..
[23:50:13] <zeeshan> and true your table surface lol
[23:50:18] <LeelooMinai> If something moves 1 mm/s it's slooow
[23:50:19] <zeeshan> rather than make it precisely to begin with
[23:50:22] <zeeshan> thought that was interesting :P
[23:50:51] <Tom_itx> zeeshan what did the cmm say about your circle?
[23:51:11] <zeeshan> i havent cut anything yet
[23:51:15] <zeeshan> still working on modbus for spindlke

[23:52:08] <rob_h> i find a CMM is ok but its not the best thing in the world
[23:52:10] <PetefromTn_> anyone have suggestions on the PID and FF1 settings or basically the rest of the axes X settings?
[23:52:23] <rob_h> i think if u just convert should be fine
[23:52:30] <rob_h> need todo encoder scale also obvisly
[23:52:40] <Tom_itx> the percentages will be the same
[23:53:07] <PetefromTn_> is it possible to make these changes, save the file, then somehow enable only one axis at a time..
[23:53:33] <zeeshan> you have 7i77 right?
[23:53:36] <PetefromTn_> yes
[23:53:40] <zeeshan> i dont think you can
[23:53:43] <zeeshan> they all enable together :(
[23:53:45] <rob_h> have to mod the hal
[23:53:53] <zeeshan> its a physical limitation
[23:53:58] <rob_h> ie comment the enable out or something like that probly
[23:54:10] <zeeshan> rob_h: that will take care of it software wise
[23:54:12] <zeeshan> but if he enables x
[23:54:16] <zeeshan> all 3 drives will eanble.
[23:54:29] <zeeshan> thats just the way ena+ stuff is handled on the physical siude
[23:54:41] <rob_h> depends how his real world wires are... true
[23:55:21] <rob_h> peter if you set the ferror small it cant go any where if it did try
[23:55:32] <PetefromTn_> this really sucks... I wish the damn tool table editor measurements were switchable... I would not have to even do this shit
[23:55:42] <rob_h> linuxcnc should stop it .. its pritty dam good at that
[23:56:20] <zeeshan> magic e-stop button :D
