02:15 AM Deejay: moin
06:00 AM Tom_L: morning
06:44 AM jthornton: morning
06:48 AM TurBoss: morning
07:01 AM miss0r: Machine shop 101: Always, at a moments notice, be prepared to extend and mount support wheels on the kids bike.
07:03 AM miss0r: the misses bought what she thought was a universal universal set. but it didn't fit the bike.
07:03 AM miss0r: unless you wanted the bike to be at 45 degrees before they catch the ground - I assumed not :D
07:09 AM jthornton: lol
07:21 AM gloops: spoiling the kids with stabilisers on the bike
07:21 AM gloops: learning to ride a bike was a do or die thing in my day lol
07:25 AM miss0r: I had stabilisers myself...
07:26 AM miss0r: We tried the broomhandle stuff there, but he hated it and didn't want to use the bike...
08:34 AM tiwake: I never got training wheels
09:03 AM _unreal_: YAWNNNNING
10:21 AM Tom_L: gloops, same with swimming
10:28 AM pcw_home: I learned on a grassy field with my father holding the bike upright, so the few spills I took were not serious
10:29 AM pcw_home: I remember the first time I rode on pavement I felt like I was flying since there was so much less drag than the grass
10:49 AM jthornton: glad to be home again
11:06 AM _unreal_: I remember my mom telling me the WALL is not the breaks
11:06 AM _unreal_: heh
11:36 AM Rab: I learned with training wheels, but I don't think it's a very good method. The most important part of cycling is balance, and training wheels take that away.
11:38 AM Rab: The hip thing for learning these days is a push bike with no pedals. After you get pretty good at cruising around by kicking, it's not a big leap to add the drive train.
12:22 PM Tom_L: it's kinda funny to watch some adults try to ride these electric scooters they have all over town now
12:38 PM jesseg: like the hoverboard things or the little mini electric bikes?
12:39 PM Tom_L: https://www.spin.app/
12:39 PM Tom_L: there's about 4 companies with em here
12:40 PM jesseg: lol
12:41 PM _unreal_: OK i'm trying to figure out what I'm doing wrong
12:42 PM Tom_L: where should we start?
12:42 PM Tom_L: :)
12:43 PM _unreal_: using fusion360 I'm trying to do a 2D contour cut. I'm milling the bottom 2mm with tabs the top 98" is a ramps milling job
12:43 PM _unreal_: but I have it setup and it keeps trying to CUT on the line rather then offset the tool to cut around th part
12:44 PM _unreal_: so instead of offsetting the 1/8th bit its putting the midle of the bit ON the edge line of my part? I dont get it
12:44 PM Tom_L: is there a tool setting for programming the center of the tool instead of the edge?
12:44 PM _unreal_: no idea
12:44 PM _unreal_: its the same "tool" from the tools list in fusion
12:44 PM _unreal_: so I dont know
12:44 PM Tom_L: that's probably where it's at
12:45 PM Tom_L: same tool but different operation
12:45 PM _unreal_: why would everything else work
12:45 PM _unreal_: I'll look
12:45 PM Tom_L: i can define multiple ops for the same tool and call them up separately
12:46 PM Tom_L: every cad is a bit different but they all should have the same basic set of operations
12:46 PM Tom_L: and that's pretty basic
12:50 PM gregcnc: anyone ever had an empty box arrive from an Ebya purchase?
12:50 PM Tom_L: not yet
12:51 PM jesseg: LOL not yet gregcnc ... What didn't you get?
12:51 PM gregcnc: small priority box wasn't sealed well and not taped, 2 sets of 7008 P4 bearings
12:51 PM jesseg: uhoh
12:52 PM jesseg: and not packed right either
12:52 PM gregcnc: yeha
12:55 PM gregcnc: nice that the postman just puts an obviously open, empty box in my mailbox so delivery confirmation shows delivered
01:06 PM _unreal_: my bits just showed up
01:06 PM _unreal_: yaya
01:06 PM _unreal_: lets see if I can get one more part milled before I have to go drive for 4 fucking hours to get my daughter
01:09 PM hightower2: Hey folks, can you give me some ideas for something I could use to mill aluminium parts
01:10 PM hightower2: I have no knowledge about this area basically, so even suggestions whether I am looking for a finished product, or a used/refurbished machine which would then be retrofitted with something, would be useful
01:10 PM hightower2: basically I need a 3d machine that's controlled by free software
01:11 PM JT-Shop: that's called a mill
01:12 PM hightower2: any suggestions for products? I would use it to machine bicycle parts, if it is relevant for precision it needs to have
01:14 PM hightower2: (small parts I mean, not frames)
01:16 PM JT-Shop: used they have many names... for hobby use a smaller mill could work for production you need a real one
01:33 PM hightower2: Got some ideas for a 1m to 1.5m size (square), up to couple K euro?
01:36 PM Tom_L: fairly large workarea for that price
01:38 PM Tom_L: https://all3dp.com/1/best-diy-cnc-router-kit/
01:42 PM Tom_L: a production mill will cost quite a bit more
01:43 PM hightower2: thanks, looking into it now
01:48 PM gregcnc: you have to be realistic about the tolerances you expect
02:00 PM hightower2: From that URL above the https://3dtek.xyz/product/heavy-mill/#review looks like the most sturdy
02:00 PM hightower2: (and with 1m or above size)
02:06 PM Tom_L: hah, i went thru their selection process and came up with about $7k
02:07 PM hightower2: yes
02:07 PM hightower2: same here :)
02:08 PM gregcnc: what kind of bicycle parts are that large?
02:15 PM hightower2: Well they're not, but since I'm making one purchase, i.e. don't intend to buy this thing multiple times...
02:17 PM hightower2: but well, probably still lack knowledge about product specs in general, so can't yet make an informed decision
02:18 PM Tom_L: you're better off finding one that will run linuxcnc. grbl will limit what you can do with it
02:18 PM Tom_L: research that as well
02:19 PM gregcnc: what kind of precision do you really need? I'd mill vs a router
02:25 PM hightower2: Tom_L, hehe yes, but as a layman I wasn't able to find a list of finished mills/routers supported by LinuxCNC
02:26 PM hightower2: On the website they list compatible hardware drivers, but when I go search for hardware on the net, I typically don't see what HW interface it has, so I can't make a link between a driver and whether a particular build is compatible
02:36 PM JT-Shop: usually ready made real mills use proprietary software and hardware
02:38 PM _unreal_: OMG..... these new single flute spiral upcut 1/8th bits are AMAZING
02:39 PM _unreal_: its like the material is not even there
02:39 PM JT-Shop: it's about time you had some success with that
02:39 PM _unreal_: way less defelection as well
02:40 PM _unreal_: THESE ARE WORTH THE MONEY https://www.amazon.com/gp/product/B078S3S956/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
02:41 PM _unreal_: I'm not get much of any melting ether using pvc or starboard
02:42 PM _unreal_: Infact before I was getting up deflection of my Zed frame when Pecking. now its pulling it down LOL
02:43 PM hightower2: JT-Shop, ok, but I also haven't been able to find instructions for building one sturdy, solid mill, to use with linuxcnc then
02:45 PM gregcnc: is the control a priority? usually the capability of the machine is more important
02:46 PM hightower2: agreed on capability (if you're asking me)
02:46 PM JT-Shop: hightower2: usually one builds from scratch or converts used machinery to use LinuxCNC, the forum has thousands of examples
02:47 PM gregcnc: if capability is the priority, you need to determine what's required to make the parts you have in mind
02:47 PM JT-Shop: with one exception Tormach uses a modified version of LinuxCNC https://www.tormach.com/
02:47 PM hightower2: JT-Shop, yes, but I don't think I'm on a level where just an example of how someone did it will help me. I need a basically complete tutorial. I agree that if I knew what I was looking for, I could help myself with the forum. But at this stage, I can't.
02:48 PM JT-Shop: I've never seen a tutorial anywhere on how to build a machine...
02:49 PM gregcnc: everyone started with nothing
02:49 PM JT-Shop: yup
02:49 PM JT-Shop: well we all started with the desire...
02:49 PM hightower2: well I guess and with basic knowledge about it... I don't have it yet
02:50 PM hightower2: I have a 3d printer (well, couple of them, one I build myself). But that's it
02:50 PM gregcnc: reading the forums is a good place to start
02:50 PM gregcnc: cnczone has several ground up builds
02:51 PM Rab: gregcnc, I've received several eBay lots of parallels, end mills, etc where the sellers just jammed 15lbs of loose metal into a USPS flat rate box. 2-3 times the box has arrived with huge holes torn by the contents; but astoundingly, everything described in the lot and photos was present, with nothing missing.
02:51 PM gregcnc: the big question is do you want to build machines and manufacture parts?
02:52 PM Rab: IIRC I received a 7" rotary table that was packed in a flat rate box.
02:53 PM gregcnc: this was a small flat rate, and you can see where the adhesive let go on the flap. it just wasn't pressed well enough to keep it together
02:53 PM Rab: So I regard those boxes as a boon for a sender, curse for a recipient.
02:53 PM gregcnc: that is where adhesive made contact it pulled paper away, but actual contact was small
02:54 PM gregcnc: So ebay said file "missing parts".
02:58 PM Rab: hightower2, what's your budget?
02:58 PM JT-Shop: I never trust the adhesive on flat rate boxes
02:58 PM _unreal_: hightower2, what kind of mill are you looking to build? or materials?
02:59 PM _unreal_: wood metal
02:59 PM _unreal_: other?
02:59 PM Rab: Aluminum, I believe.
03:00 PM _unreal_: is he going to mill the parts. hand cut? have them cnc'ed?
03:00 PM _unreal_: heh
03:01 PM Rab: Perhaps the answers lie in scrollback.
03:01 PM _unreal_: I read
03:01 PM _unreal_: didnt see anything
03:06 PM _unreal_: hightower2, still live?
03:06 PM _unreal_: Rab, currently I'm milling a multi block from PVC foam board so I can do all of the "flipping" of parts for dual side milling for the parts for this minicnc I designed right now
03:06 PM _unreal_: just got some new bits in and I'm totally in love with them
03:06 PM _unreal_: https://www.amazon.com/gp/product/B078S3S956/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
03:06 PM _unreal_: MAJOR difference over any other bit I've used
03:06 PM hightower2: _unreal_, yes, checking out OX CNC router right now
03:06 PM hightower2: supposedly it works with linuxcnc
03:06 PM _unreal_: hightower2, how are you planning to build said cnc?
03:06 PM _unreal_: hand cut parts, bolted/weld?
03:07 PM _unreal_: gregcnc, depends on how he sets up
03:07 PM _unreal_: if he does multi axis milling
03:08 PM gregcnc: which is why I expect him to answer
03:08 PM _unreal_: 4-6 axis
03:08 PM gregcnc: 73 axis
03:08 PM hightower2: yes, multiaxes would be preferred, so I don't have to attend to the machine too often
03:08 PM gregcnc: so where does toolchanger com intoplay?
03:09 PM _unreal_: hightower2, you can go multi axis Z and A axis for major ablites
03:09 PM gregcnc: router and series production/multi axis/tool changer don't really fit together
03:10 PM _unreal_: !!!! PALM TO FACE why didnt I do a pocket with the 1/4" bit first and finish with 1/8th
03:10 PM _unreal_: ARG.
03:11 PM _unreal_: hightower2, I think you need to identify what kind of features you need the machine to do before making any final decitions
03:11 PM _unreal_: decision
03:11 PM Rab: hightower2, take a look at this video: https://www.youtube.com/watch?v=S20akqg2UuQ
03:11 PM _unreal_: What is the average size of parts that may be needing multi axis functions.
03:12 PM _unreal_: That will give you an idea on the work area you need
03:12 PM _unreal_: a FULL bike frame for example would be better to have a FIXTURE that you manually flip it over.
03:12 PM Rab: Precision Matthews is a US company, which resells a very common type of asian benchtop mill. A mill like that will cut aluminum all day long, and with CNC bells and whistles will come in well under 7K EUR.
03:13 PM _unreal_: yet time for quick shower quick lunch and off to the races :(
03:13 PM _unreal_: 4 hour tour... going to pick up my daughter
03:14 PM _unreal_: sigh
03:14 PM hightower2: thanks Rab, checking
03:14 PM Rab: It's best suited for discrete aluminum parts which require rigidity, but not a lot of work envelope. The OX CNC is a router, best suited to cutting large areas of flat stock; but perhaps not rigid enough for the type of work in the video.
03:17 PM _unreal_: if you need ridged shy away from big extrusion square frame cnc's. They tend to have a lot of deflection when milling harder materials like metal
03:17 PM gregcnc: and an industrial machine https://www.youtube.com/watch?v=myDMHoYJ9Sk
03:19 PM Rab: You can mill aluminum with a router. Loetmichel in particular produces good work in Al with a chinese 6040 router, which is a very economical machine. But it might not be ideal for heavy-duty work.
03:24 PM hightower2: gregcnc, hehe, speedio is what I need :) but not in agreement with the price range tho :)
03:24 PM gregcnc: yeah, it might make sense to pay someone to make parts
03:24 PM hightower2: https://www.ebay.com/itm/Brother-Speedio-S700X1-5-Axis-Vertical-Machining-Center-BT-30-New-2017-/174028655809
03:25 PM gregcnc: that's what you're competing with, if not yet, when you release your part to market and someone sees they sell....
03:28 PM gregcnc: There were several people who documented their startups with simple machines, but once they made it, they pulled all their youtube videos
03:28 PM gregcnc: plenty start with taig/sherline/tormach and move on
03:28 PM Rab: Exhibit A (first to market): https://k-edge.com/shop/light-and-action-camera-mounts/go-big-pro-handlebar-mount-2/
03:29 PM Rab: Exhibit B: https://www.aliexpress.com/item/32945372916.html
03:29 PM gregcnc: yep. part of that is building a loyal customer base
03:30 PM Rab: Exhibit B is a bit of a gamble, though, because after flooding the market with machined aluminum mounts for a year, many manufacturers realized they could substitute painted die-cast pot metal.
03:31 PM gregcnc: sure, but most will risk 2.48USD
03:31 PM Rab: And a $400 GoPro. ;)
03:32 PM gregcnc: most don't think of it that way
03:32 PM Rab: Indeed.
03:32 PM gregcnc: it's nice they stole the original image too
03:34 PM _unreal_: later off to the races :(
03:35 PM hightower2: cya _unreal_ thanks
03:41 PM jdh: I have 4 k-edge mounts. Tried a couple of chinese clones but replaced them with real ones
03:48 PM Tom_L: mmm seems uk is gonna get hit with a winter blast
03:57 PM jthornton: not here lol
03:57 PM Tom_L: not here either
04:00 PM Tom_L: https://www.theguardian.com/uk-news/2019/jan/14/uk-weather-arctic-blast-freezing-temperatures-snow-met-office
04:02 PM Tom_L: doesn't sound like global warming to me
04:04 PM Loetmichel: *giggle* just saw a youtube-vid about a GMC crackerbox semi with a detroit diesel Turbocharged 2stroke gesehen ... Comment of the test driver:"You have hurt your thumb in the door to drive that thing right. If you are not pissed at it you dont drive it right. It REALLY doesent like low RPM!"
04:37 PM rmu: wtf 2 stroke turbo
04:38 PM rmu: diesel
04:38 PM rmu: 2 stroke diesel??
04:38 PM gregcnc: sure
04:51 PM SpeedEvil: Lots of large ship engines are 2 stroke
04:51 PM SpeedEvil: ^most?
04:52 PM infornography: *thinks*
04:53 PM jthornton: some of the smallest engines are also 2 stroke diesel
04:53 PM SpeedEvil: 'diesel'
04:54 PM infornography: diesel and two stroke makes for a pretty simple machine
04:55 PM infornography: I guess that makes sense
05:34 PM Elmo40: 2-strokes RULE!
05:35 PM Elmo40: Detroit 2-Stroke is a wicked diesel engine. youtube it. they sound like nothing else.
05:35 PM jthornton: better than a rattling Cat?
05:36 PM Rab: Elmo40, I've worked with a few of those, in buses and other vehicles.
05:36 PM * jthornton used to work on 16 cylinder EMD's that had 645 cubic inch per cylinder displacement
05:36 PM Rab: In the bus application they had a huge screw-type blower.
05:37 PM Rab: I believe it didn't develop a lot of boost, just slightly over atmosphere, but it moved a huge amount of air.
05:38 PM Tom_L: jthornton, you could probably take a nap in the cylinder
05:39 PM jthornton: not very comfortable in the cylinder but the oil pan was big enough to get inside
05:40 PM jthornton: an oil change you crawled inside the oil pan as best as you could and wiped it out with rags... can't remember how many barrels of oil it took
05:40 PM Tom_L: watched a show the other day on container ships... the guy was walking around in the engine inspecting the bearings etc for any sign of wear
05:41 PM jthornton: yea those engines are huge and slow
05:41 PM jthornton: the EMD was 900 RPM
05:41 PM Tom_L: they actually had to crank it over while he was inside to finish the inspection
05:58 PM jthornton: I saw a show a while back on the largest engine ever built for a ship and it was like 3 stories tall
06:08 PM jthornton: putzing around with the ender 3 testing some bridging settings... this print is looking good, no sagging
06:27 PM jdh: any interesting numbers. pla?
06:45 PM _unreal_: I'm back did any one miss me
06:45 PM _unreal_: I missed me
06:46 PM jym: of course
06:56 PM Tom_L: jthornton, did you get the pro?
06:57 PM _unreal_: did hightower2 ever pick something or still working out the numbers?
06:57 PM hightower2: _unreal_, nothing yet
06:58 PM skunkworks: jthornton: your directions are awesome.. Had to follow them a few times... (bad old micro sd card)
06:58 PM hightower2: _unreal_, I was mesmerized by gregc's video of https://www.youtube.com/watch?v=myDMHoYJ9Sk :)
06:59 PM _unreal_: hightower2, be aware that things like that are NOT that hard to setup but take a LOT of time
07:00 PM _unreal_: and if your not making a LOT of the same thing with a high turn over rate it quickly becomes $not worth it
07:00 PM hightower2: yeah, of course
07:00 PM _unreal_: What kind of parts do you PLAN on milling
07:01 PM hightower2: lower volumes, custom parts that are not generally available off the shelf
07:01 PM _unreal_: hightower2, give you an example. my current project https://drive.google.com/open?id=1NMDZD1AhnIh9qN-_XjH8rDLjb4nw0W1O
07:02 PM _unreal_: thats the output of this https://drive.google.com/open?id=19VlY8azpnC9eZ7JNq42H4jq3nAH1Qj13
07:02 PM _unreal_: I'm currently milling a MULTI part plate so I can take a bunch of parts and FLIP them over to do the reverse side milling easy
07:03 PM _unreal_: I could "could" produce a number of these and sell them. but from a time point of view unless I could get $275 each JUST for the body it wouldnt even be worth it. do to the milling time
07:03 PM _unreal_: then again my machine is not super fast
07:03 PM _unreal_: or large with a 7.75"x12" work area
07:03 PM _unreal_: and 1.25" Z
07:04 PM _unreal_: 1.5"
07:04 PM Tom_L: z seems to be your issue
07:25 PM Elmo40: Rab, the Roots blower was necessary. there is almost no vacuum created with these Detroit 2-strokes since they have an exhaust valve. later models incorporated turbos along with the Roots.
07:26 PM Elmo40: only 1.5" or Z?? Damn... that is tiny!
07:34 PM _unreal_: wtf. FUCK YOU MICROSOFT AGAIN
07:34 PM _unreal_: latest winbs update forces a desktop to act like a tablet
07:34 PM _unreal_: just locked me out of my cnc machine
07:34 PM _unreal_: while running
07:35 PM _unreal_: I had to pull the control cord to kill it
07:39 PM _unreal_: one thing I have noticed with these new bits. the chips its making. do NOT get picked up well milling PVC foam board. it makes these wierd lite curly worm like things
07:40 PM _unreal_: ok I'm back and zero'ed and milling again
07:41 PM _unreal_: this time I had saved the stored offset position :) muhahahahahahaha
07:43 PM Tom_L: turn off updates too
07:43 PM Rab: _unreal_, try LinuxCNC?
07:46 PM _unreal_: I LOVE linuxcnc but the controller for my HOME cnc machine is windows based
07:47 PM _unreal_: I have a planetcnc controller
07:47 PM _unreal_: the latter versions are linux capable but they WONT enable the one I have to run in linux because its "old"
07:48 PM _unreal_: Tom_L, I did and YET they have the power to overide that
07:49 PM _unreal_: milling at 500mm a min
07:50 PM _unreal_: lol
07:50 PM _unreal_: I need to make a mini cyclone seperator
07:50 PM _unreal_: I have to admit this car vacuum cleaner is working out GREAT
07:51 PM _unreal_: doesnt pick up big stuff. I expected that but does a great job with chips
07:53 PM _unreal_: I would LOVE to have something like this setup https://news.thomasnet.com/fullstory/laser-projection-equipment-shows-designs-on-work-surface-11432
07:55 PM _unreal_: any one know of any opensource systems like that?
07:57 PM _unreal_: ?
07:59 PM Tom_L: not sure why you'd need it
07:59 PM Tom_L: you know where your origin is
08:03 PM Rab: _unreal_, I got all the stuff to build this cyclone seperator. Seems pretty easy. Shame about the Photobucket links. https://forum.shapeoko.com/viewtopic.php?t=3344
08:04 PM _unreal_: photo bucket?
08:05 PM Rab: Yeah, the images linked in the thread are all degraded and fuzzy.
08:06 PM _unreal_: likely deleted and they are over sized caption images that are hostd on shapeoko
08:06 PM _unreal_: and P.U. milling pvc board not my fav.
08:07 PM _unreal_: I really should have just re done the gcode for a 1/4" end mill
08:07 PM _unreal_: just to bulk material mill it
08:07 PM _unreal_: was not expecting that @#%@#EFSA windows bs
08:08 PM _unreal_: from what little I've found if the display goes into this "mode" you cant get out of it unless you have a touch screen WTF
08:09 PM _unreal_: I love it when the numbers work out that you have to mill a 1/4 of a MM on the last pass
08:09 PM _unreal_: I mena COM ON
08:09 PM _unreal_: lol
08:10 PM _unreal_: I'm watching my machine do its thing and its like a coin pusher because I turned the vac off becuase its not doing anything
08:10 PM _unreal_: its just not picking up the shavings. wierd
08:11 PM _unreal_: its making these long stringy shavings that are like dreadlocks
08:20 PM _unreal_: when it finishes uploading I'll share a link of what the shavings look like
08:20 PM _unreal_: they are kind of messed up
08:20 PM _unreal_: My vacuum wont touch them
08:21 PM _unreal_: not much for "SMALL" dust particals with this cutter
08:22 PM Tom_L: just the result of a skin cut
08:22 PM Tom_L: no?
08:23 PM _unreal_: huh?
08:24 PM Tom_L: <_unreal_> I love it when the numbers work out that you have to mill a 1/4 of a MM on the last pass
08:24 PM Tom_L: just the result of a skin cut
08:24 PM Tom_L: the stringy shavings
08:24 PM _unreal_: no the stringy shavings are do to the new endmill
08:24 PM _unreal_: https://drive.google.com/open?id=1NRppyN5O5PAUBj-3Qqo3BgI5jUPH5a1h
08:24 PM _unreal_: nothing to do with the last cut
08:25 PM Tom_L: hmm
08:25 PM _unreal_: and I tell you I just used a stick trying to clear some of the shavings becaue they were building up under the shoe. and that new END MILL WILL FUCKING GRAB O.....M.....G......
08:25 PM _unreal_: THAT THING WILL GRAB
08:26 PM _unreal_: a straight flute doesnt grab liek this thing grabs
08:26 PM _unreal_: omg
08:26 PM Tom_L: different geometry or just sharp?
08:26 PM _unreal_: very different and sharp
08:26 PM Tom_L: ahh, spiral flute
08:26 PM _unreal_: https://www.amazon.com/gp/product/B078S3S956/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
08:27 PM _unreal_: these fuckers CUT LIKE HELL!!!!
08:27 PM _unreal_: I'm cutting material 1/3 faster then normal with out any worries of loosing steps
08:32 PM flyback: why don't you just add a encoder to avoid missed steps
08:32 PM flyback: like the inkjet printers use
08:33 PM _unreal_: the software MUST support it
08:33 PM _unreal_: the hardware MUST support it
08:33 PM flyback: https://www.google.com/search?q=inkjet+printers+encoder+strip&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiQkIKQmNTkAhVvkuAKHQYcBb8Q_AUIEigC&biw=1440&bih=750
08:33 PM _unreal_: My motion controller does not support encoders
08:34 PM _unreal_: and strip encoders are useless on cnc mills unless they are 100% sealed from dust
08:34 PM flyback: yeah I was about to say I dunno how they would hold up thete
08:34 PM flyback: oh well
08:35 PM _unreal_: the only way to encode is to use shaft encoders
08:36 PM _unreal_: Non of my stepper motors have dual end shafts only single end
08:36 PM _unreal_: so I have no location I can use to put an encoder on.
08:53 PM _unreal_: boy its quiet
09:06 PM _unreal_: well my 12v vac is now on its way out :)
09:06 PM _unreal_: just started doing the sleeve bearing BUZZ from the motor....
09:07 PM _unreal_: only it was caused by the hose being clogged. had no idea
09:07 PM _unreal_: just oiled it up and its working again
09:07 PM _unreal_: I'm not to worred about it. i figured that motor was going to be TEMP regardless. I'm going to swap it for a bldc when it does die
09:07 PM _unreal_: less power and higher rpms :)
09:31 PM _unreal_: so close to done
09:31 PM _unreal_: milling
09:52 PM _unreal_: well I feel stupid, just found an other error in my cad drawing. Not an issue just fixed it :)
09:55 PM Tom_L: what was the issue with the offset cutter earlier?
10:06 PM _unreal_: offset cutter?
10:06 PM _unreal_: which part?
10:07 PM Tom_L: no idea what part
10:09 PM Tom_L: 12:43 PM _unreal_: using fusion360 I'm trying to do a 2D contour cut.
10:09 PM Tom_L: 12:44 PM _unreal_: so instead of offsetting the 1/8th bit its putting the midle of the bit ON the edge line of my part?
10:11 PM _unreal_: oh I have no idea. I fixed it some how by using some thing I had done in my history "undos"
10:12 PM _unreal_: and it was just correct. BUT I still need to figure out how to do the roughing again. fusion360 for having such advanced features is SUCH A PITA
10:12 PM _unreal_: for nc generation
10:12 PM _unreal_: I had it setup nice once. then something changed didnt know what and it did stuff worng every time there after
10:16 PM _unreal_: Oh thank god just found an old version of carbide create on archive.org.... god damn carbide create really fucked up there latest version bad. its almost totally un usable
10:45 PM _unreal_: sigh milling the corrction now into my part
10:48 PM * _unreal_ loves milling air
10:56 PM XXCoder: _unreal_: thats new
10:56 PM XXCoder: windows only or?
10:59 PM _unreal_: windows only?
11:00 PM _unreal_: I'm finishing the last of my multi reversing jig for the parts for this mini cnc I designed
11:00 PM _unreal_: will be nice to be able to just bang them out
11:00 PM _unreal_: I could do them one at a time but I figure it would be worth it to have a flipping jig. I could then maybe sell a few of these machines :)
11:00 PM _unreal_: DIY you build it
11:01 PM XXCoder: is carbide create windows program only?
11:01 PM _unreal_: yes
11:01 PM XXCoder: oh well lol
11:01 PM XXCoder: whats wrong with latest anyway
11:01 PM _unreal_: funny you should ask EVERY THING
11:01 PM _unreal_: I mean its like a 2 year old wrote the software
11:01 PM _unreal_: so many bugs and errors and aspects that are totally broken
11:02 PM _unreal_: like you try to resize something and the entire part moves on you to a new location
11:02 PM _unreal_: menus and items are sticky
11:02 PM _unreal_: just really messed up
11:02 PM XXCoder: strange. expecially since earlier is fine
11:05 PM _unreal_: as far as I can tell at least build 413 is the best damn limited CAD major cam software out there
11:05 PM _unreal_: for cnc code generation
11:06 PM _unreal_: but My god that early version I've been using has a lot of wierd annoying bugs in it but its SOOOO damn easy to make complex nc code
11:06 PM _unreal_: 2d code
11:06 PM XXCoder: interesting
11:06 PM _unreal_: 413 a build from ? 2017 I believe
11:07 PM _unreal_: has a lot of wierd bugs. things are sticky menues are sticky and other wierd bugs but everything WORKS
11:07 PM _unreal_: and the menu system for milling jobs is a dream
11:08 PM _unreal_: Where you can adjust jobs
11:08 PM _unreal_: and order them etc...
11:09 PM XXCoder: I hjavent found a decent cam yet for linux
11:09 PM XXCoder: its virtually all windows:(
11:10 PM _unreal_: lets say I make a GRID 1/4 by 1/4 4" x4" and I want to mill it. EVERY AUTO cam software makes a crazy path that takes HOURS.. carbide. I can use the "line tool" drag over all the lines and make a nice Zig/zag snake path in both directions in a few min.
11:10 PM _unreal_: ya
11:10 PM _unreal_: as I've said before freecad is a waste of time
11:10 PM _unreal_: so over bloated
11:10 PM XXCoder: not for me, I love it
11:11 PM _unreal_: have you tried designspark?
11:11 PM XXCoder: nah
11:11 PM _unreal_: I'd suggest at least trying it
11:12 PM XXCoder: watching videp
11:12 PM _unreal_: you get past the few minore learning curves and its brain dead simple
11:12 PM _unreal_: you've seen my cad draws
11:13 PM XXCoder: windows only.
11:16 PM _unreal_: ya that I'm not a fan of
11:16 PM _unreal_: I have not bothered to get my desktop up and running yet ether :/
11:16 PM _unreal_: much better computer.
11:16 PM _unreal_: so I can leave my laptop on linux but I've been so busy trying to get all of the parts for my daughters mini cnc done
11:17 PM _unreal_: I only have a few left to go
11:18 PM _unreal_: well XXCoder some times the beast win's
11:18 PM _unreal_: windows that is
11:18 PM XXCoder: im thinking I might have to have a windows pc just for that cam stuff
11:20 PM _unreal_: XXCoder, how long do you think it would take you to design this and generate the NC code? https://drive.google.com/open?id=10MLBQXee-33djBb4kWd6c-Wew7gYVnKX
11:20 PM XXCoder: looking
11:21 PM _unreal_: thats milling assuming a 1" stock
11:22 PM _unreal_: ?
11:24 PM XXCoder: interesting
11:24 PM XXCoder: loaded linuxcnc to see what it cuts
11:25 PM XXCoder: running 3axis-tutorial
11:25 PM XXCoder: i made that vismach a while ago
11:25 PM _unreal_: how long do you think that would take you to generate?
11:26 PM _unreal_: make the cad file then make the gcode?
11:26 PM XXCoder: 3d model not too bad, but cam dunno as I dont have a method for that yet
11:26 PM _unreal_: for what?
11:26 PM XXCoder: cam
11:26 PM _unreal_: heh
11:26 PM _unreal_: I use multi softwares
11:27 PM _unreal_: for cam
11:27 PM _unreal_: carbide is my primary GOTO
11:27 PM _unreal_: I often split functions between different CAM softwares
11:27 PM _unreal_: and edit the gcode by hand
11:27 PM _unreal_: a dash of this a pinch of that ;)
11:28 PM XXCoder: cool :)
11:28 PM _unreal_: so making that part in design park and converting to gcode took me about 25min
11:28 PM XXCoder: i dont do model or programming at work
11:29 PM _unreal_: can you view SKP or stl files?
11:30 PM XXCoder: stl yeah
11:31 PM _unreal_: https://drive.google.com/open?id=1bEtuf4uRFn4xw0Ak_PECo-5kZgzVa_jk
11:31 PM _unreal_: Thats the latest build
11:31 PM _unreal_: with corrections
11:32 PM _unreal_: ?
11:32 PM XXCoder: thats pretty cool
11:34 PM _unreal_: at work I'm mostly hands on but I do cad drawings for them now and then
11:34 PM _unreal_: When they need something custom done or water jetted etc...
11:34 PM _unreal_: parts for super yachts
11:35 PM _unreal_: I've had to make drawings for things like custom vent grills to be water jetted out of glass
11:35 PM _unreal_: and aluminum parts that had to be h2o jetted for example
11:35 PM _unreal_: then install them :)
11:36 PM _unreal_: you may like "gcode ripper" they DO have a linux version.
11:36 PM _unreal_: but it will back convert gcode into cad files
11:36 PM XXCoder: maybe though my cnc project have been shelved for a while
11:36 PM XXCoder: no shop :(
11:37 PM _unreal_: I dont have a shop ether
11:37 PM _unreal_: my cnc is in my room
11:37 PM _unreal_: I'm a full time single DADA
11:37 PM _unreal_: Part of the reason why I'm building my daughter this contraption :)
11:38 PM _unreal_: So she can learn
11:38 PM _unreal_: just wondering. how much $ Interest do you have in this mini cnc design of mine? if you where to purchase one what would you expect to pay?
11:38 PM _unreal_: just wondering
11:39 PM _unreal_: ?
11:39 PM XXCoder: very hard to say. likely less money than metal chineseium machine
11:39 PM XXCoder: but how much less? dunno
11:40 PM XXCoder: I suck on market
11:40 PM _unreal_: I'm building it from starboard
11:40 PM _unreal_: starboard is is stronger by a LOT
11:40 PM _unreal_: https://drive.google.com/open?id=1NMDZD1AhnIh9qN-_XjH8rDLjb4nw0W1O
11:41 PM _unreal_: the vertical arms are 3/4" thick
11:41 PM _unreal_: you can see where I was having MAJOR problems the other day
11:42 PM _unreal_: have not tried the new milling bits on starboard yet...
11:42 PM _unreal_: spent most of the day cading and milling this parts holder so I can flip parts over and mill there ass side
11:42 PM _unreal_: considering how ruggid this mini cnc I'm making is. I'd expect at least $225-280 for it
11:43 PM _unreal_: btw starboard is expensive when it gets thick
11:43 PM _unreal_: lot of waste to build this machine
11:45 PM _unreal_: I would suggest gcode ripper. you may find it interesting
11:47 PM _unreal_: ?
11:53 PM XXCoder: price does seem reasonable
11:53 PM XXCoder: https://www.scorchworks.com/Gcoderipper/gcoderipper.html this?
11:59 PM _unreal_: yep
11:59 PM _unreal_: well off to bed with me
