[00:07:47] <zeeshan> anyone weld a bracket near a cnc controller before?
[00:07:54] <zeeshan> does it destroy the electronics :P
[00:08:23] <zeeshan> even if you keep the tungsten and ground clamp distance 5"? :P
[00:08:28] <zeeshan> with no electronics in the path

[00:54:06] <toastydeath> that's cool as shit

[09:41:07] * JT-Shop finally got Mate installed on Debian
[10:16:42] <tjtr33> JT-Shop, did you have to build MATE?
[10:16:43] <tjtr33> I'm not so happy with wheezy on a chromebook and Gnome3.
[10:43:43] <Jymmm> tjtr33: Did you expect gnome to work nicely at all?
[10:46:49] <roycroft> gnome is a festering pile of shite
[10:47:17] <roycroft> you'd be better off being honest about wanting to run crappy code and just install windows
[11:10:57] <lair82_> Hello Guys, working on my debian build, I am trying to get my touch screen driver working, and of course I am doing more stumbling around than moving forward, I found this page http://home.eeti.com.tw/LinuxDriverDownload.html and I am not sure which driver to download, any pointers?
[11:11:45] <archivist> only you know which touch screen you have
[11:12:34] <lair82_> True, all the drivers on that page apply to my screen, I don't know the linux kernel version it is asking for.
[11:13:53] <PetefromTn_> Hey lair nice to see the touchscreen getting implemented more. I have seen a couple retrofits with them using linuxCNC. Good luck with it man.
[11:15:11] <cradek> Iceweasel can't establish a connection to the server at home.eeti.com.tw.
[11:15:21] <lair82_> All three of our turning centers use touch screens, and I have never had to load a driver before, they were plug and play, we found these on ebay, got a good deal, and now the are making my god dam hair fall out
[11:15:32] <PetefromTn_> LOL
[11:15:34] <PetefromTn_> that bites
[11:15:47] <PetefromTn_> what type of screen do you use on your turning centers
[11:17:48] <lair82_> We have a couple IBM Point Of Sale touch screens, and those worked fine, but we found these because we wanted to go to a 17" screen instead of 15" like the IBM's
[11:18:24] <PetefromTn_> nice... got any pics of your working setups? Do you have a custom interface setup?
[11:22:34] <lair82_> We just run Gmoccapy
[11:23:03] <cradek> I use touchy on a lathe and a vmc
[11:23:21] <cradek> I think both touch screens just plugged in (usb) and worked
[11:23:37] <cradek> I think they are older elo something-or-other
[11:26:11] <lair82_> Here is the latest one of them, http://www.linuxcnc.org/index.php/english/forum/30-cnc-machines/27099-cincinnati-milacron-12qx60q-retrofit, here is the second one, http://www.linuxcnc.org/index.php/english/forum/30-cnc-machines/26348-2nd-cinci-up-and-running, and here is my first retrofit, http://www.linuxcnc.org/index.php/english/forum/30-cnc-machines/25774-cincinnati-up-and-running
[11:28:45] <lair82_> What Linux kernel version would a debian build be? "Kernel 2.6.24 Upwards", or "Kernel 2.6.23 Downward" or "Kernel 2.4.X" ?
[11:29:16] <archivist> uname -a in a terminal
[11:29:30] <cradek> it's not really any of those - those are ~ 6 year old numbers
[11:30:15] <lair82_> Thats what they list for a linux based operating system
[11:30:48] <lair82_> I would suppose then that "Kernel 2.6.24 Upwards" should be the right one.
[11:31:25] <cradek> well that sounds like the best guess you can make
[11:31:36] <cradek> it doesn't sound very promising, though.
[11:35:31] <PetefromTn_> wow man those look like some serious Cincinatti Iron ya got there. Thanks for sharing the pictures and builds.
[11:39:42] <pcw_home> some suggest using the usbtouchscreen driver for egalaxy rather than the proprietary driver
[11:41:33] <lair82_> By proprietary, you mean the one that comes with debian?
[11:42:25] <pcw_home> No, the one that comes from EETI
[11:49:52] <pcw_home> heres a egalaxy touchscreen howto for Ubuntu 14.04 _might be_ helpful for debian:
[11:49:53] <pcw_home> https://docs.google.com/document/d/1G4oD6Y8vlyNHW6wJT89pxcjWHoETLLT-SEoAIW6_7Xc/pub
[11:56:41] <Tom_itx> currently 16F
[11:59:03] <_methods> no thank you
[12:00:05] <lair82_> I will go give that a whirl pcw_home
[12:00:30] <pcw_home> might be close...
[12:02:42] <PetefromTn_> jeez that is getting pretty cold man.. I think we are at like 37 degrees here or so.
[12:04:59] <_methods> i guess i won't whine about how cold i am since it's 54 here
[12:05:52] <archivist> I am wearing enough layers
[12:11:18] <Tom_itx> forgot to check what it was this morning
[12:11:25] <Tom_itx> that's the noonish temp
[12:11:46] <Tom_itx> supposed to be 4 overnight
[12:12:28] <unfy> was 4F an hour ago here ._.
[12:15:18] <PetefromTn_> damn that is getting down there the coldest we have seen here was actually about two below. that is in the 15 years I have lived here anyways...
[12:16:46] <unfy> if you are from TN, where about in TN ? i've got family there
[12:17:49] <unfy> (a brother an hour or so outside of knoxville, and a cousin ... that is... somewhere)
[12:23:28] <PetefromTn_> I am about twenty minutes south of KNoxville.
[12:24:20] <lair82__> pcw_home this is all 32bit stuff right?
[12:24:46] <pcw_home> Yes
[12:25:01] <unfy> brother's just south of harriman, in Kingston.
[12:25:24] <lair82__> Would this be with "X" or without?
[12:33:44] <pcw_home> Dont know :-(
[13:54:07] <Tom_itx> pcw_home, do you know what they ended up doing on my din rail mounts?
[13:55:34] <pcw_home> I dont know, way things have been going they might ship you a bag of dog hair
[13:57:50] <pcw_home> (I know they have the adapters but they have a huge amount of stuff to ship before year end)
[15:38:22] <unfy> with a small 16x16 cnc and using the skateboard bearings (8mm inner wall) ... and going the cheap all thread route for leadscrew. would M8 threaded rod be that much beneficial over 5/16th's (7.93 mm ?)
[15:38:43] <unfy> should be less chance for vibration so i'd assume so ?
[15:46:33] <unfy> granted - 5/16 cheap all thread is what.. $6 ? a couple meters of 8m is $20 in stainless ?
[15:48:17] <unfy> do both and report back the answer i guess :D
[16:05:56] <Deejay> gn8
[16:12:48] <Tom_itx> pcw_home, NP thanks.
[18:14:39] <PetefromTn_> jeez man..
[18:14:49] <PetefromTn_> just made a bunch of parts for a customer
[18:15:00] <PetefromTn_> and they are designed to fit a particular product
[18:15:12] <PetefromTn_> they gave me one of the products to build off of
[18:15:22] <PetefromTn_> I have the parts ALMOST finished now
[18:15:30] <PetefromTn_> and they brought over another one
[18:15:38] <PetefromTn_> the new one is SLIGHTLY different LOL
[18:15:50] <PetefromTn_> so now my parts don't fit
[18:16:19] <PetefromTn_> luckily I just have to make some subtle adjustments to them and the program and we will be good again but almost had a heart attack there for a minute
[18:20:25] <unfy> that's a rage thing
[18:21:29] <PetefromTn_> actually it is probably NOT the customers fault it appears that the manufacturer has made a subtle change to the product and they did not really know it. Neither did I until I tried to fit it into my machined parts.
[18:21:54] <PetefromTn_> I left .03 all around it but that was not enough apparently so just changed the drawing and program
[18:22:10] <unfy> oh, the mfr knew it. if you tried to get replacement parts, you'd undoubtedly have to specify which version etc
[18:22:16] <PetefromTn_> if it was a LOT different it really could have screwed me here. I would have to change the whole damn part.
[18:22:34] <PetefromTn_> and made a new fixture
[18:22:39] <PetefromTn_> and reprogrammed the whole thing
[18:22:41] <_methods> nothing like building to a sample.........the wrong sample lol
[18:22:52] <PetefromTn_> and threw away a couple hundred bucks worth of aluminum
[18:23:04] <PetefromTn_> yeah I know right
[18:23:12] <PetefromTn_> they were cool about it tho.
[18:23:13] <unfy> and depending on how much of a dick you wanted to be, you could easily tell your client "you ordered parts for A. i made parts for A. parts for B will require you to buy new stuff - albeit at a heavy discount"
[18:23:30] <PetefromTn_> they even said they would help pay for new materials when we THOUGHT it was fubar.
[18:24:17] <PetefromTn_> thankfully it is just that the pocket needs to be larger on both pieces and there is thankfully enough material there to allow that.
[18:24:29] <PetefromTn_> it might actually make the part lighter which is always nice.
[18:24:49] <PetefromTn_> I did not need the stomach ache from worrying about it today tho LOL.
[18:25:02] <unfy> hehe
[18:25:27] <PetefromTn_> These guys have several more custom parts products they want me to make so I would have taken care of it regardless they are nice to work with.
[18:25:44] <unfy> that's always a plus :D
[18:26:03] <unfy> i do know that when a place takes care of me, i'll shop there reguardless usually
[18:26:11] <PetefromTn_> right now I have a bunch of parts that have to be RE-machined tho hopefully I can get them done tonight while watching TV and get back on track tomorrow.
[18:26:30] <unfy> (there's a plastics company in town that treated me right etc)
[18:27:53] <PetefromTn_> Today some friends came over and I showed them my kids Quadcopter toy. We flew the crap out of that little bastard earlier... Then we got on the subject of a custom built quad copter again and I THINK I am screwed in that light.....I am gonna HAVE TO HAVE ONE!!! LOL
[18:29:10] <unfy> have a few friends that have been building them from kits and stuff... they seem to enjoy'em a lot
[18:30:08] <PetefromTn_> even this little toy is amazing really.
[18:30:15] <PetefromTn_> it hovers effortlessly
[18:30:22] <PetefromTn_> and climbs very quickly
[18:30:29] <PetefromTn_> it can rotate left or right
[18:30:43] <PetefromTn_> it can pitch forward, backwards, and left or right
[18:30:47] <PetefromTn_> which basically means
[18:30:56] <PetefromTn_> it can go basically anywhere you want to go
[18:31:14] <PetefromTn_> if you are steady on the control it is surprisingly smooth and steady
[18:31:30] <PetefromTn_> and if you want to rip around doing loops and flips it will do that all day long too
[18:31:42] <PetefromTn_> I never would have thought it would be this controllable.
[18:31:58] <PetefromTn_> after watching many youtube videos of them there is one I really like
[18:32:05] <PetefromTn_> it is called a QAV400
[18:32:17] <PetefromTn_> and there are free frame plans online you can download
[18:32:28] <PetefromTn_> so I can try to machine one here on the VMC
[18:32:34] <PetefromTn_> which alone would be fun
[18:33:24] <PetefromTn_> trying to decide what to make it from most are carbon sheet or fiberglass sheet
[18:33:32] <PetefromTn_> which is both nasty stuff to machine really
[18:33:56] <PetefromTn_> the commercial made ones have aluminum rotor spars and CF frames
[18:34:34] <PetefromTn_> the big purchase here tho is the Remote control unit and transmitter, most of them are several hundred bucks..
[18:42:38] <Tom_itx> where are the plans/
[18:42:38] <Tom_itx> ?
[18:44:20] <Tom_itx> nm.. found
[18:46:51] <PetefromTn_> http://untestedprototype.com/2014/06/r-400-fpv-quad-plans/
[18:48:02] <Tom_itx> what did he make his out of
[18:48:49] <PetefromTn_> I think it is CF
[18:48:59] <Tom_itx> it looks heavy
[18:49:27] <PetefromTn_> yeah I agree it kinda does but keep in mind it is 400mm between rotors
[18:49:42] <PetefromTn_> and was designed to use an 8-10 inch prop apparently
[18:51:08] <PetefromTn_> The plates are ideally milled from 1.5mm fibreglass or carbon fibre, while the arms and legs are intended to be milled from 6mm fibreglass.
[18:51:34] <Tom_itx> is fiberglass heavier than carbonfiber?
[18:51:44] <PetefromTn_> The arms use the same mounting pattern as the popular QAV400/500, allowing builders to source high quality extruded aluminium or fibreglass arms and an assortment of leg solutions from various places around the world.
[18:52:05] <PetefromTn_> I would think so depending on the thickness
[18:52:27] <PetefromTn_> the G10 or whatever is pretty dense stuff and nasty to machine really
[18:52:41] <Tom_itx> i know of a guy that built one using aluminum and he was constantly bending it
[18:53:00] <PetefromTn_> you would not believe the video some of these things have captured tho. amazing stuff really.
[18:53:20] <PetefromTn_> I am sure
[18:53:47] <PetefromTn_> I would love to be able to make it from 1/8 inch plate or something cheap but it probably would kinda suck if/when you crash it.
[18:57:17] <Tom_itx> wonder how thick the carbon fiber its
[18:57:18] <Tom_itx> is
[18:58:51] <PetefromTn_> 1.5mm according to that.
[19:01:24] <SpeedEvil> That is a _terrible_ design
[19:02:04] <SpeedEvil> How on earth you expect that to be anything other than floppy, I dunno
[19:02:36] <PetefromTn_> do you have a lot of experience with quadcopters?
[19:02:38] <SpeedEvil> Specifically - it's relying on the rigidity of the beams
[19:02:55] <SpeedEvil> And not the beams being vertically tall
[19:03:32] <SpeedEvil> If you mill the base out of 12mm ply, it'd likely be more rigid
[19:03:48] <SpeedEvil> Simply due to its height
[19:05:11] <SpeedEvil> And no - I was just addressing the design.
[19:05:52] <PetefromTn_> well be that as it may there are MANY youtube videos showing some impressive flights with the same basic design
[19:06:22] <SpeedEvil> I'm not saying if you use a ridid enough plate that it can't be made to work
[19:06:52] <Tom_itx> machine it from Ti
[19:09:18] <PetefromTn_> a lot of the design is to house the motors and electronics of course but there is also a lot of discussion about vibration dampening. That may be why it is designed the way it is? I have not idea just making an observation
[19:09:56] <SpeedEvil> Oh wikipedia. I don't think that word means what you think it does.
[19:09:59] <SpeedEvil> 'Approximate (to 6 significant digits) specific stiffness for various species of wood[50]'
[19:11:55] <Tom_itx> the frame is extremely stiff due to the materials chosen and construction methods applied. This model uses black anodized, milled aluminum arms
[19:12:10] <SpeedEvil> http://en.wikipedia.org/wiki/Specific_modulus is useful - the number you care about for beams where the vertical height is unconstrained, but the weight is not - is youngs modulus / density^3
[19:12:18] <Tom_itx> body is G10
[19:12:20] <Tom_itx> whatever that is
[19:12:29] <Tom_itx> probably a carbon fiber
[19:13:19] <SpeedEvil> Spruce may be several times better than CF - simply as it's lower density
[19:13:19] <Tom_itx> FR4
[19:13:31] <Tom_itx> so it's not cf
[19:13:37] <PetefromTn_> we machined a bunch of G10 at the shop I worked in
[19:13:39] <_methods> yeah pcb magterial
[19:13:40] <Tom_itx> same as circut board
[19:13:45] <PetefromTn_> it is nasty stuff really
[19:13:47] <Tom_itx> i got plenty of that
[19:13:59] <PetefromTn_> really? Send me some LOL
[19:14:08] <_methods> hehe
[19:14:14] <_methods> copper clad both sides plz
[19:14:17] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/etching/Copper2.jpg
[19:14:21] <Tom_itx> _methods, it is
[19:14:34] <_methods> oh wow you do have a pile of it
[19:14:42] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/etching/Copper3.jpg
[19:14:44] <_methods> i'll be right there
[19:14:46] <Tom_itx> and a few sheets
[19:14:52] <PetefromTn_> what thickness?
[19:14:57] <Tom_itx> .062
[19:15:06] <XXCoder1> copper
[19:15:27] <PetefromTn_> thats probably too thin and the copper plating is not desirable for this application
[19:15:33] <Tom_itx> funny, i got rid of most of it
[19:15:40] <Tom_itx> we had about 2 pickups full
[19:15:41] <_methods> wut?
[19:15:49] <_methods> you could have sold it on ebay
[19:15:53] <Tom_itx> tried
[19:15:56] <_methods> really?
[19:16:04] <Tom_itx> several years back
[19:16:23] <_methods> i buy mine from some guy in mass. on ebay
[19:16:41] <_methods> he sells small cut up pieces
[19:16:50] <_methods> 6x6 or so
[19:16:55] <Tom_itx> that first pic was just part of the cutoff we picked up off the boardhouse floor
[19:16:58] <_methods> 12x12
[19:17:06] <PetefromTn_> wait a minute... actually that is 1.5mm LOL
[19:17:18] <Tom_itx> sounds about right
[19:17:20] <_methods> yeah .o6
[19:17:29] <_methods> 1mm is approx .04"
[19:17:31] <PetefromTn_> damn you got the quadcopter mother lode.
[19:18:07] <Tom_itx> i'm gettin kinda tired of stubbing my toe on it
[19:18:10] <_methods> hehe you won't need wires just cut traces
[19:18:48] <PetefromTn_> exactly that would be sweet
[19:18:50] <_methods> don't they make those miniflies like that
[19:18:56] <_methods> just put it all on a pcb?
[19:19:19] <PetefromTn_> if you watch the videos the factory made ones actually have solderable traces for some of the electronics on the base plates.
[19:19:52] <Tom_itx> i think that's 2oz copper but i honestly can't remember
[19:20:08] <_methods> http://dangerousprototypes.com/2013/02/25/quadcopter-in-a-5x5cm-pcb/
[19:20:11] <PetefromTn_> probably would not affect the weight all that much really but I dunno
[19:20:17] <Tom_itx> it works whenever i need a board
[19:20:54] <PetefromTn_> with four 8-9 inch probs and that kinda power it would probably be negligible difference in performance
[19:22:10] <_methods> oh crazyflie is the one i was thinking about
[19:22:13] <_methods> http://www.bitcraze.se/crazyflie/
[19:23:07] <PetefromTn_> Tom_itx How much would you sell me enough plate to make two of those 400 models for? you can PM me if you want.
[19:26:27] <PetefromTn_> if you wanted to sell any at all LOL
[19:31:14] <The_Ball> Made some gang tooling on the mill: https://wigen.net/owncloud/public.php?service=files&t=7fc571d948dbeacb08d374383649e398
[19:31:19] <The_Ball> Works a treat
[19:33:26] <PetefromTn_> neato
[19:33:36] <PetefromTn_> is that an ER32 holder?
[19:33:41] <PetefromTn_> what did you make with it?
[19:36:53] <_methods> The_Ball: did you do something to lock your column?
[19:37:13] <_methods> i have one of those mills sitting at work the boss said i could have
[19:37:23] <The_Ball> _methods, no, just clamp it with the original bolts?
[19:37:57] <_methods> i heard they columns have a tendency to move when machining
[19:38:05] <_methods> we only ever used it as a drill press at work
[19:38:17] <PetefromTn_> I once saw a cool parallelogram clamping setup someone made for those machines that allowed you to raise and lower while maintaining alignment.
[19:38:28] <PetefromTn_> I used to have one and it was actually quite nice.
[19:38:29] <The_Ball> _methods, I do have to re-position everything when I raise or lower the head of course. I've never had the head spin on the column if I've remembered to tighten it properly
[19:38:38] <archivist> use a lot of muscle to tighten the column clamps
[19:38:54] <_methods> i might take it then
[19:38:55] <The_Ball> I've forgotten to tighten it properly plenty of times
[19:39:06] <archivist> I got rid of mine as soon as I could
[19:39:10] <PetefromTn_> I actually did have to replace the column bolts with better larger ones but it was solid as a rock once it was tightened down.
[19:39:35] <_methods> maybe i won't take it then lol
[19:39:38] <The_Ball> _methods, for free you can't really go wrong, but it's very entry level of course
[19:39:39] <_methods> but free mill
[19:39:41] <_methods> yeah
[19:39:53] <_methods> well i have one of the little x2 clones
[19:40:01] <archivist> as a drill they are ok, very solid
[19:40:03] <The_Ball> my next one will have a proper dovetail on the z for sure
[19:40:13] <_methods> yeah we only ever used it as a drill press at work
[19:40:18] <PetefromTn_> I tig welded some barstock to the nuts so it would not rotate on the other side and used larger bolts.
[19:40:38] <PetefromTn_> I had both the RF31 and the RF45
[19:40:45] <_methods> i was thinking aobut taking and just making a square column for it or something
[19:40:54] <PetefromTn_> the RF45 was better but it had its own issues.
[19:41:13] <PetefromTn_> really the little round column was a nice machine and very smooth cutting due to the belt drive
[19:41:31] <The_Ball> PetefromTn_, I believe this is the RF45, I can't imagine how the rest of the machine would hold up if you manage to move the head with the original bolts clamped down
[19:41:35] <PetefromTn_> If I got one for a good price let alone free I would grab it and use it for a manual mill.
[19:41:53] <Tom_itx> PetefromTn_, figure out how much you need and let me know
[19:42:10] <PetefromTn_> no actually that is the RF31 or at least a clone of it.
[19:42:22] <PetefromTn_> the RF45 was a square dovetail column machine
[19:42:26] <_methods> yeah the barrel switch went out on it and it's just sitting in a corner rusting
[19:42:29] <The_Ball> PetefromTn_, ah ok, thanks for clearing that up
[19:42:43] <PetefromTn_> methods I would probably just put a VFD on it anyways.
[19:42:52] <_methods> oh yeah?
[19:43:12] <_methods> that's actually a good idea
[19:43:14] <PetefromTn_> sure and a 2 or 3 hp 3phase motor which is easy to change out..
[19:43:16] <_methods> i might have to do that
[19:43:53] <_methods> well couldn't i just use the motor on it already?
[19:44:01] <_methods> why would i need a vfd and a new motor?
[19:44:08] <PetefromTn_> a guy I shoot airguns with just got a real good deal from Enco on an actual RF31, it is white and sitting in his shop now. He said he paid less than a grand for it I was kinda shocked because the Harbor Freight ones are that much or close to it now.
[19:44:27] <PetefromTn_> well the machine is probably single phase motor now no?
[19:44:39] <_methods> yeah single phase i'm pretty sure
[19:44:41] <PetefromTn_> if it is 3 phase you are good to go with just a vfd most likely.
[19:44:56] <PetefromTn_> you can get small hp motors for it pretty cheap.
[19:45:05] <_methods> the motor is good though
[19:45:06] <PetefromTn_> or just replace the switch
[19:45:11] <archivist> http://www.diycnc.co.uk/html/my_project.html
[19:45:11] <_methods> just the on off switch is gone
[19:45:18] <PetefromTn_> or sell the motor and get a 3ph one.
[19:45:50] <PetefromTn_> is that yours archivist?
[19:46:10] <archivist> hell no
[19:46:11] <_methods> the one at work is like 2x that size
[19:46:23] <PetefromTn_> yeah that actually looks like an RF30
[19:46:27] <archivist> I did have the alpine badged one
[19:46:37] <PetefromTn_> the RF31 is actually a good sized little machine.
[19:46:37] <_methods> we must have a rf45 at work then
[19:46:55] <_methods> oh is the rf31 the bigger round column one?
[19:47:01] <PetefromTn_> again the RF45 is square column and geared head with dovetail
[19:47:06] <PetefromTn_> yeah
[19:47:19] <PetefromTn_> apparently
[19:47:24] <PetefromTn_> mine was the larger one
[19:47:27] <The_Ball> archivist, is that your site?
[19:47:30] <archivist> my column was not square to the XY
[19:47:30] <_methods> ah yeah it must be the rf31 at work
[19:47:36] <archivist> The_Ball, no
[19:47:36] <PetefromTn_> grizzly has a different name for it
[19:47:58] <PetefromTn_> you can shim under the column
[19:48:09] <archivist> I was just googling for alpine milling machine images
[19:48:56] <PetefromTn_> http://thumbs2.picclick.com/d/l400/pict/390646397981_/MILL-DRILL-eg-RF-31-JET-BIRMINGHAM.jpg
[19:48:57] <_methods> wow i had no idea those things were that expensive
[19:49:02] <PetefromTn_> that is what mine and my friends looked like
[19:49:02] <_methods> i thought they were like $500 lol
[19:49:22] <PetefromTn_> they used to sell the RF31 at harbor freight for like $899.00 or so
[19:49:34] <PetefromTn_> plus the stand was another hundred or so.
[19:49:35] <The_Ball> archivist, been planning a ballscrew upgrade like that for a long time, but I'm finally moving house and will upgrade my mill to something sturdier
[19:50:43] <PetefromTn_> like I said I had both the round column and the square column machines and they were both nice. The round one was a pretty decent manual machine I would have another one if I got a good deal.
[19:51:00] <_methods> well i can't bitch about free
[19:51:11] <_methods> i'll have to make some room in the garage lol
[19:51:28] <_methods> i need some room at work where the damn thing is sitting anyways
[19:51:46] <_methods> we just not a new pemserter set up there and it's all in the way
[19:51:50] <The_Ball> I built a cage around mine a long time ago, took up too much room though: https://wigen.net/workshop/zx30/IMG_0243.JPG
[19:51:52] <_methods> s/not/got
[19:52:15] <PetefromTn_> https://www.youtube.com/watch?v=kV0xi6SrOSM&list=UUFCopiUpaDrS5VBkrYFuGFQ&index=9 this is my youtube video showing my old RF45 conversion. Sorry for the crappy video...
[19:52:20] <_methods> oh wow that paint
[19:52:29] <_methods> it actually has paint on it lol
[19:52:46] <_methods> so shiny
[19:53:31] <PetefromTn_> yeah I totally stripped it down and refinished it. It was light green when I got it.
[19:54:22] <The_Ball> PetefromTn_, that's a nice conversion!
[19:54:39] <The_Ball> pitty about the mach ;)
[19:54:45] <PetefromTn_> yeah I know right LOL
[19:54:54] <PetefromTn_> that was back before I knew anything about linuxCNC
[19:55:02] <PetefromTn_> but I did put a LOT of work into that machine.
[19:55:15] <_methods> it's a heavy bastard
[19:55:38] <PetefromTn_> I sure as hell would not trade it back for my CIncinatti arrow 500 but it was a nice machine while I had it. It would have probably been even nicer with linuxCNC.
[19:56:34] <The_Ball> PetefromTn_, do you still have/use the RF45?
[19:57:46] <The_Ball> PetefromTn_, my dad has what I believe is the RF45, it's got a dovetail head and a geared spindle, wondering if it's worth converting, or would you choose something else today?
[19:59:14] <_methods> i think the rf45 is supposed to be superior to the rf31 for conversions but i don't know
[19:59:26] <_methods> i've never converted either
[20:01:09] <PetefromTn_> I do not any longer own the RF45. I bought it almost fifteen years ago now for $1500.00 brand new, kept it manual for a LONG time and converted it about four years ago or so. Used it to learn CNC and made all sorts of stuff with it. Finally sold it for about $6k complete and with the CNC stuff and some tooling
[20:01:34] <PetefromTn_> Used the money to buy my Cincinatti Arrow 500 and have been retrofitting and running that machine for about a year or so now.
[20:02:38] <PetefromTn_> if you do not have any interest in making any real money with the machine and want a decent mill to convert that will fit in any garage shop the RF45 is a great little machine.
[20:02:53] <PetefromTn_> I actually made some cash with it here and there making parts for local customers
[20:03:56] <PetefromTn_> but compared to the VMC it is a toy and not nearly as powerful, rigid, or accurate. For most parts that don't need to be better than say .001" or so it was fine tho. if I HAD to I could do even better but it took a lot of fiddling and farting aruond with it.
[20:05:09] <PetefromTn_> after going thru all the trouble of retrofitting that machine and refinishing it, adding the belt drive, new motors, ballscrews, encoders, one shot oiler, etc. etc. etc..
[20:06:00] <PetefromTn_> I would definitely recommend if you can find a decent used CNC machine to retrofit it is MUCH MUCH easier to start with something that is already CNC with ballscrews and everything than to build all of that stuff.
[20:13:28] <The_Ball> PetefromTn_, sorry at work so lost focus.
[20:13:39] <PetefromTn_> yeah me too. running parts right now
[20:14:26] <The_Ball> PetefromTn_, yeah all that makes sense, I'll keep my eyes open
[20:17:55] <XXCoder1> man
[20:18:33] <XXCoder1> I love sriracha candy canes
