12:03 AM jesseg: Howdy Folks
12:06 AM XXCoder: yo
12:06 AM XXCoder: pink_vampire: so wghats you sandblastibngv
12:06 AM pink_vampire: the tool setter
12:06 AM pink_vampire: hi jesseg
12:06 AM pink_vampire: i can make a video feed
12:12 AM pink_vampire: XXCoder: http://www.ustream.tv/channel/21137007
12:13 AM pink_vampire: jesseg:
12:16 AM pink_vampire: is it working?
12:16 AM * jesseg looks around
12:16 AM pink_vampire: i go to the sandblast box, so write to me on the chat over there
12:16 AM jesseg: well it shows a black view
12:16 AM gloops: mine will work today
12:16 AM XXCoder: black also
12:16 AM * gloops prepares for final victory in the field
12:16 AM jesseg: pink_vampire, Doesn't seem to be working for me.
12:16 AM jesseg: pink_vampire, oh OK I'm getting sound. but no video
12:19 AM pink_vampire: mmmm
12:19 AM pink_vampire: let me see
12:19 AM gloops: jthornton spotted the missing link in my ini files, thats why hanging around in here is useful, i wouldnt have spotted that for ages, if it all
12:21 AM gloops: and having watched the gantry sim, i now understand how a gantry (2 motors) works
12:24 AM gloops: you first get a jog screen with joints 0 1 2 4 etc, you can jog though, until the homing cycle is complete, the joints 0124 then changes to XYZ
12:24 AM gloops: cant jog
12:28 AM `Wolf: need to learn to walk before you can run?
12:28 AM gloops: so when you get to XYZ you then have a normal axis machine ready to run, i never got that far, but i will today
12:28 AM `Wolf: =p
12:28 AM XXCoder: pink_vampire: not trying live stream again?
12:28 AM pink_vampire: i try to find a way
12:29 AM pink_vampire: any idea?
12:29 AM XXCoder: sadly no
12:29 AM pink_vampire: i wish it was like a video room
12:29 AM gloops: its good that things wont work sometimes, it forces you to learn, ive had a couple of days working on ini and hal files, i know my way round those now, or a lot of them anyway
12:29 AM pink_vampire: so every one can talk
12:30 AM XXCoder: would be useless to me
12:31 AM `Wolf: gloops: its been over a year since I have run my lcnc machine so I’ll almost be releaning when I set up my next mill lol
12:32 AM gloops: Wolf surprising how soon the memory goes - i hadnt used linuxcnc since last summer, it takes a while to come back, but it does come back
12:32 AM `Wolf: right now I would be happy if I could remember were I put my hakko flush cutters….
12:36 AM jesseg: I wouldn't even mind knowing where your hakko flush cutters are. :P
12:37 AM `Wolf: more on amazon lol was $15 for 5 of them
12:49 AM gloops: looking at drilling 3 stepper motor shafts to get a tapered pin in, slipping as i knew they would with screws
12:49 AM gloops: they dont drill too easy
12:50 AM Cromaglious_: I have life! it LIVES!
12:50 AM gloops: woohoo!
12:53 AM gloops: remind me what you were working on Cromaglious?
01:00 AM IchGucksLive: morning from germany
01:01 AM gloops: hello
01:02 AM XXCoder: hey
01:03 AM pink_vampire: errr
01:05 AM IchGucksLive: gloops: whats on today first 2hr test
01:06 AM gloops: Ichs yes more testing, too early to work in garage though
01:08 AM gloops: i wont be building any more cnc machines for a while i can tell you haha
01:10 AM gloops: i will start collecting bits for a 4 axis router though
01:10 AM IchGucksLive: you will be getting more praxis
01:11 AM IchGucksLive: beleve me im buildin one after one
01:11 AM IchGucksLive: d3z1b3l: Guten Morgen
01:11 AM IchGucksLive: gloops: i can tell easy as i got only 4-5 systems
01:12 AM IchGucksLive: and build them in seri
01:12 AM gloops: well im not an engineer or a machine builder, i only want them for myself to use, i cant afford to buy ready made machines
01:12 AM IchGucksLive: ready made bearly fit needs
01:13 AM gloops: true yes, big money for a proper machine of good size
01:13 AM IchGucksLive: its always a compromise on work and material
01:13 AM IchGucksLive: gloops: this only can fit a homemade
01:13 AM IchGucksLive: and you got a first choice to make
01:14 AM IchGucksLive: 280 OR 420 Euros to spend
01:14 AM IchGucksLive: meening sbr or hiwin
01:14 AM IchGucksLive: then on Framing AL vs Wood
01:15 AM IchGucksLive: meening 80Euros or 250Euros
01:15 AM XXCoder: all machine have comproses. just select best fit
01:15 AM gloops: same size as the one ive mad are going for 5-10k new, on ebay, i think ive spent about £900
01:15 AM IchGucksLive: look at sorotec prices
01:15 AM gloops: i would have spent a bit more on ally profiles for the main rails, looking back, steel is hard work and time consuming
01:16 AM IchGucksLive: yes 45x90 is the perfect fit
01:16 AM gloops: i will use it next time
01:17 AM pink_vampire: I'm trying something
01:17 AM gloops: ive mad all kinds of things from steel, trailers, frames etc, i cannot believe it took this long to get a few pieces of box section right for a gantry
01:17 AM gloops: weeks pass!
01:18 AM XXCoder: one word made it harder.
01:18 AM XXCoder: "precision"
01:18 AM gloops: well it remains to be seen how much of that i got as well XXCoder lol
01:18 AM IchGucksLive: http://www.tecwalker.com/aluprofile-baureihe10-raster45.html
01:19 AM XXCoder: :)
01:19 AM XXCoder: honestly almost anyone can slap together a box
01:19 AM IchGucksLive: XXCoder: stiffnes is the goal
01:19 AM XXCoder: making it work for cnc is harder
01:19 AM gloops: it isnt bad actually, everything moves ok, the screws and bearings wouldnt allow it without fairly close tolerances
01:20 AM pink_vampire: how do i share a live video on instagram?
01:21 AM gloops: yes Ichs, steel is ok for the table, alu for the gantry and x support rails
01:21 AM IchGucksLive: if you can turn the leadscrew with 2fingers full way it is goiing on 3Nm like hell
01:21 AM IchGucksLive: its 9Euros per meter
01:22 AM IchGucksLive: best on Al Konstruction is all profiles fit together with screwing
01:22 AM IchGucksLive: bad Price
01:24 AM IchGucksLive: if your side rail needs more change from 45x60 to 45x90
01:24 AM IchGucksLive: and on to 135 180
01:24 AM gloops: well, i dont suppose anybody ever listens until theyve tried and learned the hard way
01:24 AM IchGucksLive: <- SMILES
01:25 AM IchGucksLive: a entirer school setup on lcnc went to WIN
01:26 AM IchGucksLive: and now askes fro reset to new lcnc
01:26 AM pink_vampire: https://www.instagram.com/pink.cnc/
01:26 AM pink_vampire: i started a live feed
01:26 AM IchGucksLive: pink_vampire: your cnc got its own profile
01:26 AM XXCoder: it does make it look great
01:27 AM pink_vampire: on istegram you need to see a live feed
01:27 AM XXCoder: only see one picture?
01:27 AM IchGucksLive: pink_vampire: lightning colector ?
01:27 AM jesseg: pink_vampire, I don't have instagram account, however I see a picture of a little aluminum thing or something
01:27 AM jesseg: but no video yet.
01:28 AM IchGucksLive: im off 2 "work"
01:28 AM jesseg: Have "fun"
01:28 AM jesseg: :P
01:28 AM pink_vampire: you need to open it from instagram
01:29 AM jesseg: instagram.com?
01:29 AM jesseg: oh, the app?
01:29 AM pink_vampire: the app
01:29 AM pink_vampire: yes...
01:29 AM XXCoder: oh no app
01:29 AM pink_vampire: it only ask for email
01:30 AM XXCoder: no "app" on linux pc :)
01:30 AM pink_vampire: app on the cellphone..
01:35 AM pink_vampire: i try again
01:35 AM pink_vampire: Wolf__: ?
01:35 AM pink_vampire: Wolf_ITX: ?
01:35 AM `Wolf: what
01:36 AM pink_vampire: do you see my live feed?
01:36 AM `Wolf: nope lol
01:37 AM `Wolf: I was over at the other bench fixing a fiberoptic amp
02:09 AM Deejay: moin
02:17 AM Crom: Upload install video's
02:18 AM Crom: Uploading CNC Fusion X2 kit
02:20 AM gloops: right, i think working, synchronised homing of 2 joints, got the speed back, just a stupid slipping pulley stopping me from a proper test, cant sort that out just yet too early to making noise
02:23 AM Crom: I have a bent ball screw on the X, I had to drill and tap new holes for the NEMA 24 steppers. Integrated closed loop steppers, nice and quite, cept for the bent screw
02:24 AM Crom: running off my cnc3040 PS and BOB
02:24 AM gloops: shouldnt affect operation Crom? except at high speed maybe
02:24 AM Crom: gloops: yep
02:25 AM Crom: go it up to 5.1 in/s
02:26 AM gloops: thats pretty quick, is it a long screw?
02:27 AM gloops: mine is bent on Y, it doesnt seem to causing any problem, but only been playing with it while testing
02:27 AM gloops: all my stuff was bent when it arrived, rails screws
02:31 AM Crom: the longest screw
02:32 AM Crom: going to take my thrust bearing plate and mod it for more travel on my buddies 33686
02:35 AM gloops: well im gonna have another cup of tea then strip these pulleys off
02:36 AM Crom: also looking at my saddle to see if I can turn the X ball nut around and have is ontained within the saddle
02:36 AM Crom: just finished my last cuppa for the night...
02:37 AM gloops: it would be nice to just finish the mechanical and press the button and it all works, it never happens like that though, this works, that doesnt, this nearly works, you dont get the final satisfaction before another round of messing about
02:39 AM Crom: I notched the base plate to be able to drop in the Y ball screw, trimmed the Y ball nut mount, to fit into it's hole at an angle
02:39 AM Crom: Had to grind the end off the Y screw to fit into the base
02:41 AM Crom: it was 3mm too long
02:43 AM Crom: https://www.youtube.com/watch?v=-XS9o2lHqiU It's alive!
02:43 AM gloops: excellent, cant beat that feeling when it first moves
02:46 AM XXCoder: hiding behind drawer eh ;)
02:48 AM Crom: The computer is on the table with the 3040, made one extension cable to drive one motor
02:48 AM gloops: cant find lead for my camera to upload vids, memory card gone in phone, people should be a bit more considerate moving my stuff, this is serious sht!
02:48 AM pink_vampire: Crom: how you did the live on youtube?
02:48 AM XXCoder: pink there should be stream in upload page?
02:49 AM XXCoder: could be wrong, never needed to stream
02:49 AM pink_vampire: there is no
02:49 AM Crom: on phone youtube app.
02:49 AM pink_vampire: i have it
02:49 AM pink_vampire: but i can't see the live option
02:50 AM Crom: click the camera top right, should have option record, GO LIVE, or saved video's
02:50 AM pink_vampire: you can take a screen shot?
02:55 AM `Wolf: pink_vampire: https://i.imgur.com/4MyIF1e.jpg that button…
02:56 AM pink_vampire: i don't have it
02:56 AM XXCoder: hmm is it logged in>
02:56 AM pink_vampire: hoooooooooooooooo
02:56 AM `Wolf: are you logged in
02:56 AM pink_vampire: one sec
02:56 AM Crom: hyy[p://ibb.co/bx7MUR
02:57 AM pink_vampire: i think i know what is the issue
02:57 AM Crom: http://ibb.co/bx7MUR
02:57 AM `Wolf: ^ thats the next screen
02:58 AM Crom: ordered a new router to replace both pieces of Shite I have
02:59 AM XXCoder: your spindle died?
03:00 AM `Wolf: this thing is pretty neat https://i.imgur.com/AelWIDc.jpg
03:01 AM pink_vampire: what is that?
03:01 AM XXCoder: spindle control?
03:01 AM `Wolf: fiber optic amp
03:01 AM `Wolf: sensor
03:03 AM Crom: heh, spindle died while back. Got an aircooled 1.5kw haven't finished the wiring for the 220
03:03 AM Crom: inet router is getting replaced
03:03 AM XXCoder: never could find replacement brushs?
03:04 AM Crom: tossed the 400w DC POS!
03:04 AM `Wolf: the two little plates that are screwed together are the “send/receive” units, docs read that its sensitive enough to detect 0.005mm wire
03:05 AM XXCoder: cant use that dc for something else? lol
03:05 AM fragalot: Wolf__: yeah they work really well. :)
03:06 AM fragalot: Wolf__: it's just a bit annoying that the optical lead is always too short for what I need them for
03:06 AM `Wolf: lol yeah, I could see that
03:06 AM Crom: probably cut off the collet chuck and use it in my ER32 chuck
03:06 AM `Wolf: thinking optical tool length/diameter sensor
03:07 AM XXCoder: if I recall right, the collet is easily removable
03:07 AM fragalot: `Wolf: interesting concept
03:07 AM `Wolf: would beat using a touch plate
03:08 AM fragalot: certainly would, though it would be more complex
03:08 AM XXCoder: wolf I saw one video where guy used laser to do pre-measurement of tool length, then it would use touch plate for faster but accurate measurement
03:08 AM fragalot: if you have a tiny tiny V-bit and you touch Z off-center
03:08 AM fragalot: so you would need to scan for Z
03:08 AM XXCoder: then it rapids stright to exactly top of jaw jeez lol
03:08 AM pink_vampire: Record and stream from the YouTube app. Note: For YouTube live on mobile, your channels must have over 100 subscribers
03:08 AM XXCoder: 100 dang impossible lol
03:09 AM `Wolf: XXCoder: why do you think I have the thing on my desk lol =]
03:09 AM `Wolf: saw the same vid lol
03:09 AM Crom: I have 17 subscribers
03:09 AM XXCoder: 4? for me lol
03:09 AM pink_vampire: 0 for me
03:09 AM `Wolf: I think I have 2
03:09 AM Crom: what's your channels?
03:10 AM fragalot: I have 4 too.. God knows where those came frmo
03:10 AM XXCoder: couple is from this channel lol
03:10 AM fragalot: must have been when jI had a video ofo my reprap running at 850ipm
03:10 AM Crom: nite nite bedtime for Bonzo
03:11 AM XXCoder: apparently cheeeap https://www.youtube.com/watch?v=iPlo4A1xXSs
03:11 AM fragalot: as that is almost the only video i have, lol
03:11 AM fragalot: that, and a cow eating my DIY tricopter
03:11 AM XXCoder: one channel has 2 random videos. other has few cnc router videos
03:12 AM `Wolf: wow I have 26 subs lol
03:12 AM fragalot: showoff
03:12 AM `Wolf: how I have no idea lol
03:12 AM * fragalot gives pink_vampire a free sub
03:12 AM `Wolf: Wolfmetalfab is my youtube...
03:13 AM pink_vampire: https://www.youtube.com/channel/UCCjJVBLH6qwO4zEeRXpi74w
03:13 AM XXCoder: mines xxcoder :P
03:13 AM fragalot: Wolf__: you've had enough!
03:13 AM pink_vampire: this is my channel
03:13 AM archivist: I probably win with number of views for a vid
03:15 AM `Wolf: probably
03:15 AM pink_vampire: still no option for live
03:16 AM fragalot: my top vid apparently has 637, surely that is something to be proud of
03:16 AM pink_vampire: and i even did the phone verification
03:16 AM archivist: 101 subscribers and 668k views on one vid
03:16 AM fragalot: pink_vampire: your subscription rates are going through the roof!
03:16 AM `Wolf: top is 1410 views… and its a unlisted vid lmao
03:16 AM fragalot: Wolf__: hahah
03:17 AM XXCoder: 190 highest viewed video lol
03:17 AM fragalot: youtube's not really my thing to post things on
03:17 AM `Wolf: when I was doing a test on a nano quad FC lol
03:17 AM fragalot: the reward is negligible, and the effort is insane
03:17 AM XXCoder: 114 highest directly cnc related video
03:19 AM Crom: wow I have a video with over 1k vews
03:25 AM Crom: https://youtu.be/uOO879rhJF8
03:25 AM pink_vampire: https://hangouts.google.com/call/Fli8eMxiL7iCXwkX0HWCAAEE
03:26 AM pink_vampire: is that any good
03:26 AM pink_vampire: ?
03:27 AM `Wolf: yeah, i forgot about that
03:27 AM XXCoder: zero views crom?
03:27 AM XXCoder: had to close video. autofocus makes me dizzy sadly.
03:27 AM XXCoder: worse than handheld
03:35 AM Crom: You were the first to watch it then
03:35 AM XXCoder: watched maybe minute of it before focus changes made me dizzy
03:36 AM pink_vampire: :(
03:36 AM Crom: Looking for better camera's and better tripods
03:36 AM XXCoder: and lighting
03:36 AM pink_vampire: are you using the phone or the computer?
03:36 AM XXCoder: theres cheap led bar lights now
03:37 AM Crom: XXCoder: My main light is a LED shop light
03:37 AM Crom: phone
03:37 AM pink_vampire: errrr
03:37 AM XXCoder: or maybe very cheap light panels using light strips and light scattering sheet. cheao
03:38 AM XXCoder: once we finally build a shop, we probably will use those led inserts lights. great light
03:38 AM fragalot: I'm quite enjoying my camera
03:38 AM `Wolf: yay more crap installed on this computer now
03:39 AM Crom: I need to pick up some more LED shop lights
03:39 AM Crom: $40 at Home depot
03:39 AM fragalot: cheap, they're €65+ here
03:39 AM fragalot: for the crappy ones
03:39 AM XXCoder: not bad. costco has special deal, and tacoma city pays for some of it. so its $25 here
03:40 AM `Wolf: I got 4’ x6 for $55 on amazon
03:40 AM `Wolf: I also have some costco lights that were $25 each
03:40 AM Crom: I need to get up to costco the
03:41 AM Crom: htn
03:41 AM Crom: well nite nite, wife has declared bedtime
03:41 AM XXCoder: not sure if still sells em. I saw they had better versions but same price
03:41 AM XXCoder: but that was bit ago also
03:41 AM `Wolf: lol got google hangouts working, no one else there of course
03:42 AM XXCoder: i was there but didnt stay long. no point as I cant do talky part :P
03:42 AM `Wolf: yeah
03:43 AM gloops: close, very close
03:54 AM gloops: strange thing, x joints = 0 and 1, if i jog them individually, they move the same direction for + and - on the jog button, but when homing they search in opposite directions - had to invert search velocity for 1 motor
04:03 AM pink_vampire: https://gaming.youtube.com/channel/UCCjJVBLH6qwO4zEeRXpi74w/live
04:04 AM XXCoder: hmm trying to figure what I am seeing
04:05 AM XXCoder: ah
04:06 AM pink_vampire: Crom: ^
04:06 AM pink_vampire: do you see it?
04:06 AM XXCoder: he already left for bed
04:06 AM pink_vampire: :(
04:07 AM pink_vampire: Crom_: ^^
04:07 AM pink_vampire: https://gaming.youtube.com/channel/UCCjJVBLH6qwO4zEeRXpi74w/live
04:07 AM `Wolf: lol is that a airbrush being used as a sandblaster?
04:08 AM pink_vampire: no
04:08 AM pink_vampire: type in the youtube screen
04:08 AM pink_vampire: the sandblast is not in front of the computer
04:13 AM pink_vampire: the video is any good?
04:13 AM XXCoder: its bit rough but then usual for phone and handheld
04:14 AM pink_vampire: i'm starting a new part
04:14 AM pink_vampire: 2024-T3 aluminum
04:16 AM XXCoder: the refocuses is also not nice to me bleh heh
04:19 AM slipalong: Hi anybody have any experience of these Chinese 4Kw spindle motors?
04:19 AM slipalong: Specifically taking the collet holder off.
04:20 AM XXCoder: 4kw or 400w?
04:20 AM slipalong: 4Kw
04:20 AM slipalong: want to fit it to a Mill
04:20 AM XXCoder: cool dunno on those
04:23 AM slipalong: Trying to work out if I can remove the closet holder to fit a pully
04:24 AM slipalong: collet holder
04:24 AM archivist: probably not if that is the spindle itself
04:25 AM XXCoder: pics or its impossible
04:25 AM `Wolf: most of those china spindles look like they are made in
04:26 AM XXCoder: made in <country not found>? dang
04:33 AM pink_vampire: so, how do you like my stream?
04:34 AM `Wolf: watching sandblasting is kinda meh ;p
04:34 AM pink_vampire: LOL
04:35 AM XXCoder: reminds me too much of my previous job
04:35 AM XXCoder: sandblasted hundreds of parts
04:35 AM XXCoder: in hot summer (shop temp was 85f or so) with long thick arm coverings
04:35 AM XXCoder: I had to steal a fan to keep myself cool
04:35 AM pink_vampire: i need to sandblast the base
04:36 AM `Wolf: meh, worst things to do
04:36 AM `Wolf: try welding in 100f weather...
04:36 AM `Wolf: total suck
04:36 AM XXCoder: fun
04:36 AM XXCoder: dont do any welding myself
04:37 AM jthornton: morning
04:38 AM `Wolf: full leather welding coat, hood, gloves, in some pain in the ass position under a truck for 4-5 hrs
04:38 AM pink_vampire: do you think I can do tig here>
04:38 AM XXCoder: if I ever do welding it will be in very confortable position
04:38 AM pink_vampire: ?
04:38 AM XXCoder: no backbreaking, as my back is bad enough
04:38 AM `Wolf: big isn’t bad
04:39 AM `Wolf: been thinking about bringing my tig box in to the basement here
04:39 AM `Wolf: tig* isn’t bad
04:39 AM XXCoder: oh just got pay increase at work. first job I ever had that gave me pay rainses twice
04:40 AM `Wolf: Trump tax shit
04:40 AM XXCoder: huh
04:40 AM `Wolf: my take-home went up this month
04:40 AM XXCoder: no its end of year evaluation for me
04:40 AM `Wolf: oh double bonus then lol
04:40 AM XXCoder: I'm about to arrive at 3 years worked so far
04:41 AM XXCoder: also means my cnc is 5 years old lol
04:41 AM XXCoder: too damn ittle use
04:41 AM `Wolf: lol
04:42 AM `Wolf: only thing with tig welding indoors you need to watch out for is outgassing crap that is on the parts you are welding
04:42 AM pink_vampire: i need a shop
04:43 AM `Wolf: I need a bigger shop…
04:43 AM `Wolf: which I’m working on lol
04:43 AM pink_vampire: lets share a space.
04:43 AM `Wolf: add about 1500sqft to my house
04:43 AM gloops: holy sheep, 30 minutes trying to anlyse homing problem, eventually decided to check wire for breaks, got to the end of the wire - not in switch
04:44 AM XXCoder: if(shop.exists() == true) shop.needBigger() = true;
04:44 AM XXCoder: doh gloops
04:44 AM `Wolf: love county zoning, I need to make house bigger so I can make the shop out back bigger
04:44 AM gloops: done too much on this now lol
04:44 AM XXCoder: then house again? ;)
04:45 AM `Wolf: no, i don’t really need a big house lol
04:45 AM `Wolf: just me in 1400sqft
04:45 AM pink_vampire: me too
04:45 AM XXCoder: actually wolf that makes sense, because I once saw a house at old place, its garage is 3 door one, and taller and bigger than orginial house
04:45 AM XXCoder: owner killed probably 25 evergreens on its lot
04:45 AM `Wolf: yeah, thats common in my area
04:45 AM `Wolf: attached garage = part of the house
04:46 AM XXCoder: its... bare spot compared to houses around it
04:46 AM XXCoder: thing is it wasnt attached.
04:46 AM `Wolf: skips over the zoning issues
04:46 AM `Wolf: attached is a loose term, a breezeway between them means attached lol
04:47 AM XXCoder: yeah but it wasnt at all
04:47 AM XXCoder: orginially it was just house surrounded by nice and VERY tall evergreens
04:47 AM XXCoder: owner probably pissed off lot of neighbots.
04:48 AM `Wolf: *shrug* most everywhere around here has zoning for outbuildings can’t exceed a set ratio to the homes sq footage
04:48 AM `Wolf: unless its farm or commercial property
04:49 AM XXCoder: farm type gets abused so much by rich
04:49 AM XXCoder: huge lots taxed like farm, and even credits. but no farming going on
04:54 AM Wolf__: farms in this area end up subdivided and full of houses...
04:54 AM pink_vampire: https://i.imgur.com/r4KhnVt.mp4
04:55 AM XXCoder: same idea as that worm toy thing
04:58 AM gloops: what happens if you weigh 24 stones?
04:59 AM XXCoder: it turns into siccors
04:59 AM XXCoder: cant spell that word :P
05:00 AM Wolf__: if you weigh 24 stones then it goes to furlongs per fortnight speeds
05:01 AM gloops: plus would need to bounce harder on hills
05:01 AM XXCoder: I guess people awesome on sex would rock that thing so hard
05:02 AM Wolf__: people awesome at sex dont just bounce
05:03 AM gloops: thats the next logical adaptation
05:07 AM XXCoder: no, but sure has good musicles to dos o
05:09 AM Wolf__: could be someone made it for him because pedaling was too complex of a task
05:10 AM XXCoder: or he made it himself for same reason
05:24 AM laminae: Anyone alive at the moment?
05:24 AM archivist: no
05:24 AM malcom2073: Nope
05:24 AM laminae: I had my suspicions
05:24 AM jthornton: maybe after one more cup of coffee
05:25 AM XXCoder: unfair to all those unalives
05:25 AM laminae: So, full disclosure, i'm one of those 3d printing geeks that is creeping into the dark side
05:25 AM malcom2073: laminae: That's what I did
05:25 AM archivist: rofl
05:25 AM laminae: You're all the dark side
05:25 AM laminae: just fyi
05:25 AM malcom2073: I now have over 3 tons of CNC machines :)
05:26 AM laminae: Haha, well i'm a little overwhelmed choosinga controller, and i don't mind paying for software but there is some much confliucting information between mach4 or linux cnc
05:26 AM laminae: or which boards function well
05:27 AM Wolf__: easy
05:27 AM malcom2073: Linuxcnc allows you to use (almost) any comptuer with a parallel port, and even some without with additional hardware
05:27 AM jthornton: I tried mach once...
05:27 AM laminae: I scooped up a c-beam machine kit and don't know which board i should control it with
05:27 AM malcom2073: mach4 requires an external controller
05:27 AM Wolf__: dont pay for software (Lcnc) and get mesa stuffs
05:27 AM malcom2073: Find yourself a cheap old computer, and throw linuxcnc on it
05:27 AM archivist: quite a few are coming to linuxcnc because it can do things mach can only dream of
05:27 AM jthornton: laminae: steppers?
05:27 AM laminae: 23 nemas
05:28 AM XXCoder: laminae: it was opposite for me. first cnc, then reprap :P
05:28 AM laminae: Hold on, grab a link to original kit
05:28 AM jthornton: https://mesaus.com/index.php?route=product/product&path=69&product_id=78
05:28 AM laminae: http://openbuildspartstore.com/openbuilds-c-beam-machine-xlarge/
05:28 AM laminae: Oh no, Xxcoder is here!
05:28 AM jthornton: https://mesaus.com/index.php?route=product/product&path=66&product_id=66
05:28 AM XXCoder: shhh
05:29 AM jthornton: or a 7i92M + 7i76
05:29 AM laminae: I do most of my modeling in fusion and i see it has a option to generate gcode and i know pocket nc controllers recognize that
05:29 AM laminae: do others as well?
05:29 AM Wolf__: gcode works on most all real cnc stuff
05:29 AM XXCoder: you have poicket nc?
05:30 AM Wolf__: post processing on the gcode may differ for different controllers tho
05:30 AM laminae: Negative
05:30 AM laminae: Just would love the convenience of exporting gcode natively
05:31 AM Wolf__: if you want a rough idea of what lcnc and mesa gear can do look at what the tormach cnc machines do
05:31 AM XXCoder: apparently there is new pocket nc. https://www.youtube.com/watch?v=s4pliuHi_Uk
05:32 AM laminae: jthorton: i assume you're suggesting the pair?
05:32 AM laminae: Yeah 5 axis
05:32 AM archivist: hobbing is lcnc only :)
05:32 AM laminae: sexy as hell
05:32 AM XXCoder: it LOOKS better. but no idea if it sounds the same lol someone menioned it sounded awful
05:33 AM laminae: The idea of 5 axis that cheap is beatiful to me
05:33 AM XXCoder: $5k is not cheap to average person
05:33 AM XXCoder: but 5 axis yeah
05:34 AM XXCoder: https://www.youtube.com/watch?v=XHN2EFwahiI
05:34 AM laminae: WHy is there so little documentation on the 7i76?
05:38 AM XXCoder: heyy diy https://www.youtube.com/watch?v=joGv4ErUJgY
05:38 AM jthornton: what do you mean
05:39 AM jthornton: laminae: http://www.mesanet.com/pdf/parallel/7i76man.pdf
05:39 AM XXCoder: using brass gear and steel worm gear to preload
05:40 AM laminae: Just can't seem to find many builds running it
05:42 AM jthornton: have you looked on the forum?
05:42 AM gloops: got it, 3 axis homing like a dream, still cant get to XYZ layout because no switch on z axis, homing sequence cant complete
05:43 AM gloops: that is a minor issue once i find the switch
05:43 AM jthornton: gloops: manual home the z
05:43 AM XXCoder: you can change it to manual home for z
05:43 AM gloops: good thinking i can try that
05:43 AM archivist: laminae, people document their first build but by the time they are using mesa documentation takes a back seat
05:43 AM gloops: 0000 all home values
05:43 AM * XXCoder is so glad linuxcnc has actual manual homing. flipping 3d printers dont have that
05:44 AM gloops: or i think there is an ignore home or something, ill try the manual first
05:44 AM laminae: Sorry got distracted reading that link
05:44 AM laminae: That makes sense
05:44 AM laminae: Setup looks simple enough
05:44 AM malcom2073: XXCoder: Sure they do, you're just using the wrong interface. Most of them support G92
05:44 AM XXCoder: automated homing with switches or something?
05:44 AM malcom2073: That too
05:45 AM laminae: ANy particular stepper driver to consider? i was looking at dq 542ma because that's what is suggested on the website
05:45 AM gloops: first im going to save these hal and ini files on multiple drives, murphys law wont catch me this time
05:45 AM XXCoder: ugh tormach uses lght gray on white
05:45 AM XXCoder: ah malcom2073 suppose can do that but eh
05:46 AM malcom2073: XXCoder: That's the same thing linuxcnc does
05:46 AM XXCoder: careful, murphy may go to extreme means to hit you
05:46 AM XXCoder: well gonna sleepo night
05:46 AM malcom2073: murphy usually does heh
05:48 AM jthornton: laminae: the G203V is thee best stepper drive for 80vdc
05:48 AM jthornton: http://www.geckodrive.com/geckodrive-step-motor-drives/g203v.html
05:48 AM jthornton: smaller brother http://www.geckodrive.com/geckodrive-step-motor-drives/g251x.html
05:50 AM laminae: Hmm, i'm guess the big bnrother would be overkill for my build? what would you suggest
05:50 AM jthornton: voltage = speed in the stepper world
05:51 AM archivist: servos are faster
05:51 AM laminae: I don't think my spindle or frame could hand the kind of kit you guys are throwing around
05:51 AM * jthornton wonders how many thousands of 7i76's are running machines
05:51 AM gloops: servos = 1500-3000rpm or more, steppers = 600 rpm
05:52 AM laminae: I'm out of my element Donny!
05:52 AM gloops: what are you making laminae?
05:53 AM malcom2073: jthornton: I wonder how many are *not*? :P
05:53 AM malcom2073: My dad has one, sitting on a shelf
05:53 AM malcom2073: Has been for years now
05:53 AM laminae: cbeam xl
05:53 AM laminae: http://openbuildspartstore.com/openbuilds-c-beam-machine-xlarge/
05:53 AM laminae: Most of the names i work with are 17's, it's a whole new world man
05:53 AM laminae: nemas*
05:54 AM malcom2073: I have some nema34's on my mill, I almost got 42's
05:54 AM gloops: myself, i wouldnt buy the electronics from them, or at least i would compare the prices, you can get good deals on ebay
05:54 AM malcom2073: But yeah I have 17's on my 3d printer, they're so cute and tiny
05:55 AM laminae: I really wanted to do a pro 4896 but i'm moving within a year definitely wouldn't want to move it once it's set up and it would have left me totally tapped and unable to buy materials to learn on and play with
05:55 AM gloops: 36v psu, 280 or 425 oz steppers will do that imo
05:56 AM gloops: these are £20 motors
05:57 AM laminae: Which controller of the two would you choose? do you think i'll be able to hit that 80v ball park witht his little guy?
05:57 AM laminae: Driver*
05:58 AM laminae: the 50v max notes 17 through 34 so i was leaning that way
05:59 AM laminae: but again, way out of my element
05:59 AM gloops: drivers? the dm542a or similar are popular, copy of the leadshine model, actually in the us i think the genuine leadshines are the same price, 50v max
06:00 AM gloops: you cannot put more volts through, it trips a red light
06:01 AM gloops: right, found my switch, i could be 30 minutes away from knowing if my gantry works
06:02 AM laminae: jthornton was suggesting these: http://www.geckodrive.com/geckodrive-step-motor-drives/g251x.html
06:04 AM jthornton: they are bullet proof and have mid range morphing
06:04 AM archivist: that frame looks flimsy for real milling
06:04 AM gloops: he knows a lot more about it than i do, i mainly look at low price stuff too, there is cheap stuff that is proven to work reliably, but obviously there are better products, the geckos have a good reputation
06:04 AM laminae: The mesa ethernet board is very appealing to me
06:05 AM gloops: that is the way to go if you can spend a little more
06:05 AM laminae: Those geckos are only ten bucks more apeice than the 543s anyway
06:06 AM gloops: no brainer then
06:06 AM laminae: Dammit, the mesa is out of stock
06:07 AM jthornton: of what?
06:07 AM laminae: 7i76e
06:08 AM jthornton: yea they are building them atm, should be back in stock in a few weeks
06:09 AM * jthornton unplugs the monitor for a while to see what happened to the RPi Zero wlan0
06:09 AM laminae: Might take me that long just to get the rig built anyway
06:13 AM archivist: laminae, before you get too far, what are you going to make/machine
06:14 AM laminae: delrin hdpe and alum plates
06:14 AM laminae: mostly parts for making 3d printers
06:19 AM gloops: 700 notes, v bearings
06:20 AM laminae: In a perfect world it would be linear rails
06:21 AM gloops: ballscrews?
06:21 AM laminae: Yeah
06:22 AM gloops: should be ok then
06:24 AM laminae: What wattage were you thinking on the psu?
06:24 AM gloops: 4
06:24 AM gloops: oh wattage
06:24 AM archivist: er more that that
06:24 AM laminae: 4 watss? i'll turn on an led
06:25 AM gloops: 350-400
06:25 AM gloops: 4 amp
06:25 AM laminae: The linked one was 24v 500 watt, which if i'll get better performance out of something beffier i'm all bout that
06:25 AM laminae: As long as there's a buck converter or something on the board
06:25 AM archivist: 24v is a bit low
06:25 AM gloops: it will give more amps but generally around 4 for bigger steppers
06:26 AM gloops: get higher volts
06:26 AM laminae: https://www.amazon.com/Adjustable-Converter-110V-220V-Switching-Transformer/dp/B0777MH681/ref=sr_1_4?ie=UTF8&qid=1517660543&sr=8-4&keywords=48v+power+supply
06:26 AM gloops: if i turn the volts down on mine there is a distinct difference
06:26 AM laminae: https://www.amazon.com/Eyeboot-AC110V-Universal-Regulated-Switching/dp/B01L5GHEU6/ref=sr_1_3?ie=UTF8&qid=1517660747&sr=8-3&keywords=36v+power+supply
06:26 AM gloops: like this http://www.ebay.co.uk/itm/UK-EU-36V-350W-9-7A-DC-Switching-Power-Supply-For-CNC-Router-3D-Printer-DIY/112723750305?
06:27 AM gloops: thats ok what you posted
06:27 AM laminae: Seems close to th 36v 400w one
06:27 AM laminae: Awesome
06:28 AM laminae: THe mesa board is electrically isolated from the drivers right?
06:28 AM gloops: they give out more than 36v, all 3 ive got do anyway
06:28 AM laminae: relays?
06:30 AM gloops: back to the theatre of operations
06:36 AM laminae: Suggestions on spindle?
06:39 AM * JT-Shop starts a fire while waiting on etcher to finish flashing
07:02 AM laminae: jthornton: still around?
07:06 AM gloops: right im in, 2 motor gantry works
07:06 AM archivist: it was that easy!
07:06 AM gloops: easy
07:07 AM gloops: still got slipping pulleys though so racking when jogging, but software side - working
07:07 AM archivist: what time is the red tape opening ceremony
07:07 AM gloops: you dont get to XYZ layout till all joints are homed
07:07 AM gloops: archivist probably another week of messing about with this lol
07:08 AM jthornton: yea, monitor was connected to the RPi for a while
07:09 AM gloops: i might leave it for today now, the design and build over months was all hinged on that 2 motor axis working, and ive seen it now lol
07:10 AM archivist: should have done that part earlier, less worrying time
07:10 AM gloops: i might just do something else, anything but drilling, welding, reading manuals
07:11 AM gloops: archivist i was going to set the motors up with flags and get it sorted - but then my screws arrived
07:13 AM gloops: in fact, no..i will just get these pulleys sorted today then thats it
07:27 AM jthornton: damn wide angle RPi camera has slightly different bolt pattern than the official one
07:40 AM IchGucksLive: hi from snowing germany
07:40 AM IchGucksLive: d3z1b3l: ?
07:41 AM IchGucksLive: later
08:01 AM Tom_L: morning, afternoon on the odd side of the pond :)
08:01 AM jthornton: lol
08:02 AM Tom_L: well i finally figured out the easy way to get dxf into my old cad cam
08:02 AM Tom_L: it want's to see a full 3d model on import
08:02 AM Tom_L: so iges or sat etc only
08:03 AM Tom_L: 32F
08:03 AM Tom_L: and most cad import it as a drawing file
08:03 AM Tom_L: flat
08:05 AM jthornton: we are up to 28°F
08:06 AM Tom_L: doesn't make me feel any warmer
08:06 AM jthornton: chickens are being lazy this morning only 2 eggs so far in 4 hours
08:07 AM Tom_L: o
08:07 AM Tom_L: it's henry's fault
08:08 AM jthornton: yea he is still in the dog house lol
08:45 AM gregcnc_: pro tip: if you get a super deal on a carbide boring bar and it cuts awesome, don't crash it at first chance.
08:45 AM archivist: that was the cheap price to lock you in
08:46 AM gregcnc_: just a good deal on ebay
08:47 AM archivist: making my own boring tools for 2mm id holes was fun, watching it flex
08:48 AM gloops: redesigning pulley fixing method next, bigger bolts
08:49 AM gloops: 4x4mm bolts
08:49 AM Tom_L: (they can't be bigger than the shaft)
08:49 AM Tom_L: they shouldn't be bigger than the shaft radius
08:49 AM gloops: ill need new shafts soon lol
08:49 AM * Tom_L gives gloops a box of grub screws
08:51 AM gloops: used tiny grubs screws, hex head screws same thread to tighten harder, just vibrates them loose
08:51 AM gloops: its only on the motors, the pulleys on the screws are solid
08:51 AM Tom_L: back it with a 2nd grub screw
08:51 AM gloops: its got 2 in
08:51 AM Tom_L: weld them in place
08:51 AM gloops: i might use some superglue or resin to steady them
08:53 AM gloops: you need a split collar with an o clamp
08:55 AM gloops: these screws are for holding wires in a light fitting, not clamping a 4 inch pulley on a shaft
09:15 AM archivist: gloops, taper lock are good
09:17 AM archivist: taper in the pulley, flange pushing a taper collet into the gap around shaft
09:18 AM gloops: ill have a think about it
09:20 AM archivist: I found a couple at a model engineer show
09:20 AM fragalot: What's wrong with taper lock?
09:20 AM archivist: nothing
09:21 AM archivist: someone is having trouble with grub screws :)
09:22 AM fragalot: That's what you get for using the chinese ones made of slag rather than metal :P
09:22 AM gloops: it is along the right lines the taper lock bush
09:23 AM gloops: i cannot have a machine of this magnitude depending on piddling screws
09:23 AM fragalot: if your car can depend on glue joints to stay together, machines can rely on grub screws
09:24 AM gloops: something a little more substantial is required
09:24 AM fragalot: larger grub screw
09:24 AM fragalot: (what are we talking about? I missed the beginnning)
09:27 AM gloops: just pulleys slipping on motor shaft, already got flats, 2 screws
09:27 AM fragalot: taper pin?
09:28 AM gloops: shaft doesnt like drilling
09:28 AM gloops: that was my first design plan
09:28 AM fragalot: loctite the pulley on
09:28 AM fragalot: hope it never has to come off
09:28 AM fragalot: if it does.. heat.
09:29 AM gloops: that might work, theres obviously some clearance and its working its way loose, if it was bedded in with something so it cant wiggle
09:30 AM fragalot: also, when you say 2 screws, are they both on the same side, or opposing?
09:30 AM fragalot: if opposing, get rid of one.
09:30 AM gloops: at 90 degrees
09:30 AM fragalot: that's fine
09:32 AM gloops: well, it can be sorted anyway ill go back to it
09:33 AM gloops: it runs long enough to make a vid lol, ill get one tommorrow
09:33 AM fragalot: :)
09:34 AM fragalot: does anyone here have experience with acrylics?
09:34 AM Tom_L: depends what you want
09:35 AM fragalot: I have a cylinder where I need to insert some baffles, but I can't use screws... how well does glue wick in, and what clearance should I aim for?
09:35 AM Tom_L: Weldon #4 solvent
09:35 AM Tom_L: it's a water like liquid that gets in the cracks
09:36 AM * fragalot gets on the gargler to see if he can get that here
09:36 AM fragalot: so the clerance should be a sliding fit?
09:37 AM Tom_L: yeah fairly snug but enough so liquid can wick in
09:37 AM fragalot: alright, thanks :)
09:37 AM Tom_L: http://www.ipscorp.com/
09:39 AM Tom_L: http://weldon.com/wp-content/uploads/2015/03/SELECTION-GUIDE-COMPLETE-SET-2017.pdf
09:39 AM Tom_L: they may have changed their numbering
09:40 AM fragalot: can't seem to find weldon in europe
09:40 AM Tom_L: look for an acrylic solvent
09:41 AM fragalot: am doing so :-)
09:41 AM Tom_L: #16 was a tube (paste)
09:41 AM Tom_L: #4 was a liquid
09:42 AM fragalot: I have a tube of acrifix that's a paste.. tried that but it does not wick at all
09:42 AM Tom_L: no the solvent works better
09:42 AM Tom_L: i use a syringe to apply it in a corner
09:50 AM fragalot: christ
09:50 AM fragalot: acrifix makes a 5-component glue
09:50 AM fragalot: FICE.
09:50 AM fragalot: FIVE*
09:51 AM fragalot: "here are the ingredients. enjoy"
09:57 AM fragalot: found some 0,6mPa stuff -- thanks Tom_L :-
10:56 AM Louis_Cypher: Hi everybody
10:57 AM Louis_Cypher: May I ask for a recommendation about stepper wiring
10:57 AM Louis_Cypher: ?
10:57 AM fragalot: Asking is free.
10:57 AM Louis_Cypher: I am planning to use two ballscrews and two steppers to move the gantry of my machine
10:57 AM jthornton: just ask the question
10:58 AM Louis_Cypher: Would you suggest to hardwire those two motors or would you synchronize them in linuxcnc?
10:59 AM Louis_Cypher: I was thinking of connecting the input wires of the motor drivers to the same terminal to have them running synchronos
10:59 AM Louis_Cypher: I will use a belt between the motors to force synchronisation as well
11:00 AM Cromaglious: Today Make cables and BOB Box
11:01 AM archivist: Louis_Cypher, if you have a belt you only need one motor
11:01 AM fragalot: yeah a belt over 2 motors is going to fight more than it's going to work
11:01 AM Cromaglious: Louis_Cypher: look at jmc-motor.com iHSS57-36-20 NEMA23 Integrated closed loop steppers
11:02 AM archivist: two screws and two motors can easily be used as well
11:02 AM Cromaglious: then setup homing to synchronize them
11:02 AM Louis_Cypher: Are you sure? The Motors should be pretty accurate right?
11:03 AM Louis_Cypher: Why should I home two motors that do the same thing seperately? That will cause a lot of forces on the gantry, right?
11:03 AM archivist: linuxcnc has a homing mode for two motors to get the gantry square
11:04 AM Louis_Cypher: OK. So you are saying that I should synchronize them in linuxcnc
11:04 AM fragalot: Cromaglious: I've always wondered if those are true "closed loop" or more "error checking"
11:05 AM Cromaglious: fragalot: you more the lead screw with a wrench, motor fights you to move it back to position
11:05 AM Louis_Cypher: "yeah a belt over 2 motors is going to fight more than it's going to work" => My thinking was that the motors should be an order of magnitude more accurate than the play in the belt
11:05 AM fragalot: Neat.
11:05 AM Cromaglious: you move
11:05 AM fragalot: so true closed loop
11:05 AM fragalot: Louis_Cypher: if they are, then why bother with the belt?
11:05 AM Louis_Cypher: I just want the belt for emergency in case one motor has a broken wire or the like
11:06 AM Louis_Cypher: If that happens my gantry will be bent for sure
11:06 AM archivist: Louis_Cypher, use servos and feedback then linuxcnc will stop
11:06 AM Cromaglious: yep, I have 11 of them now 3ea NEMA23 iHSS57-36-20, 6ea iHSS60-36-30, and 2 NEMA17 closed loop steppers with drivers
11:06 AM fragalot: Louis_Cypher: if it's loose enough that it's going to work as a backup only, then sure.
11:06 AM Louis_Cypher: Aren't hose pretty expensive?
11:07 AM Louis_Cypher: That was the idea
11:07 AM fragalot: Cromaglious: I've got 3 86J18118EC-1000 motors with 3 2HSS86H drives from jmc
11:08 AM fragalot: well, from rattm, but I would be surprised if he doesn't get them from jmc too
11:08 AM Cromaglious: Louis, 1 price for encorder, stepper, and driver. NEMA24 2Nm (285) oz in iHSS57-36-20 motors are $125ish with shipping
11:09 AM Cromaglious: 86 ah NEMA34
11:09 AM Louis_Cypher: That'll be aroung 450$ for two of them including taxes ant toll. That's a lot
11:10 AM fragalot: Louis_Cypher: your belt idea as backup if it's slack enough is fine.
11:10 AM Cromaglious: and no headache of loosing synch
11:10 AM fragalot: just don't put it on guitar string tight
11:10 AM Louis_Cypher: My original setup uses one Nema 23 for two ballscrews but I am fearing that will be to weak to run both screws
11:10 AM fragalot: but you will need a way to have both motors home correctly
11:11 AM fragalot: so they can't use the same electrical signal
11:11 AM Cromaglious: then you trade speed for power and gear down the motor
11:11 AM Louis_Cypher: That was why I was thinking of connecting to one and the same pin on the BOB
11:11 AM fragalot: Louis_Cypher: but how does that guarantee both home?
11:11 AM Cromaglious: Louis_Cypher: Linuxcnc will home synchronized motors and synch them
11:12 AM fragalot: Louis_Cypher: the gantry can shift when not powered, so they must both be re-homed to a known position
11:12 AM fragalot: so you can't use the same pin
11:12 AM Louis_Cypher: It is only the gantry that has to be homed, right? As long as the motors are synchronous homing only once should be fine
11:12 AM fragalot: in other words - use a different pin, different home sensors, and let linuxcnc handle it
11:12 AM fragalot: Louis_Cypher: sure, but you can't gaurantee that when the power is off
11:13 AM Louis_Cypher: that's how I use it on my shapeoko (running GRBL)
11:13 AM Cromaglious: i agree with fragalot, you're asking for LOTS of trouble if you don't
11:13 AM fragalot: not unless your belt is super tight between them
11:13 AM Louis_Cypher: OK, got it
11:13 AM fragalot: and if it's super tight, you will have the motors fight eachother
11:13 AM Louis_Cypher: On my Shapeoko the expperience was different
11:14 AM Louis_Cypher: The Motors were fighting each other via the gantry
11:14 AM Louis_Cypher: after rigidly connecting them (rod) they wordked like a charm
11:14 AM Cromaglious: Louis_Cypher: yeah and it's using a grbl basically?
11:14 AM fragalot: shapeoko's have a lot of play that allows for flexing though
11:15 AM Louis_Cypher: Motor accuracy should be round 0.25° or even better
11:15 AM Louis_Cypher: Yes it is
11:15 AM gloops: ive just got a 2 motor gantry running, just run home all at startup, both motors start off bang in step, when you close linuxcnc you need to home again
11:15 AM Cromaglious: Iordered a smoothieware board, and I have plenty of mega 2560/Ramps boards running Marlin as well
11:15 AM Louis_Cypher: That's right. That's why I built the new one
11:16 AM gloops: its essential to keep them homed - thats the whole point, if one misses steps youre running out of sync
11:16 AM Cromaglious: and running closed loop steppers basically making loosing a step impossible
11:16 AM Louis_Cypher: OK, so I will connect them with a *loose* belt and home both motors at a time
11:16 AM Louis_Cypher: right?
11:17 AM Louis_Cypher: Can I setup a two motor setup in stepconf?
11:17 AM gloops: you dont need a belt accross the motors
11:17 AM fragalot: Louis_Cypher: Yes.
11:17 AM fragalot: gloops: he wants one just to help him sleep.. no issue with that
11:17 AM Louis_Cypher: just want to be sure that the gantry isn't bent when things go wrong (they will)
11:17 AM fragalot: Louis_Cypher: actually i'm not sure if stepconf can, but you can certainly edit the hal file to do it
11:17 AM gloops: no stepconfig doesnt set up gantry
11:17 AM Louis_Cypher: had broken wires on my Shapeoko a coule of times
11:18 AM fragalot: Louis_Cypher: but gloops is an EXPERT on setting up dual motor gantries by now
11:18 AM gloops: ive got working hal an ini files, ill post them on the forum or somewhere
11:18 AM Louis_Cypher: that's good (and it's a pitty that stepconf can't do it
11:18 AM Louis_Cypher: that would be great
11:18 AM Louis_Cypher: Which forum?
11:18 AM gloops: fragalot youve never seen a proper gantry lol
11:19 AM Louis_Cypher: One more:
11:19 AM Cromaglious: Shapeoko uses crap wires. I use MIDI or DMX RDM cables that I cut up
11:19 AM gloops: linuxcnc - if youre here occassionally i can send them, not got them on this PC atm though
11:19 AM Louis_Cypher: What is the maximum speed of a Nema 23 approximately
11:19 AM Louis_Cypher: ?
11:19 AM fragalot: gloops: does a Seramill 410 count?
11:19 AM Cromaglious: Louis_Cypher: depends on price
11:19 AM Louis_Cypher: Mine is completely wired by myselfs
11:19 AM gloops: im getting around 6000mm/min atm, still testing though, and i have geared up
11:20 AM Louis_Cypher: Maybe that's even worse ;-)
11:20 AM Cromaglious: Louis_Cypher: Clearpath servo (setup as step and dir) can do 4000 rpm
11:20 AM Louis_Cypher: I have seen your pictures gloop
11:20 AM Louis_Cypher: Great machine
11:20 AM Louis_Cypher: I just wanted to calculate my approximate max speed
11:21 AM Louis_Cypher: Currently running 1600 steps per turn
11:21 AM Cromaglious: Louis_Cypher: my JMC-motor.com 's are good to around 1500-1800 RPM since clearpath is a servo and my jmc's are steppers
11:21 AM Louis_Cypher: 2000mm/min with load would be sufficient for my machine
11:21 AM gloops: yes for speed you want servos or closed looped steppers really, remember you need the screws to handle the rpm as well though
11:22 AM Louis_Cypher: THanks, that's good enough for a guess
11:22 AM Louis_Cypher: If I have to gear up, the synch belt doesn't make any sense anymore or I do have to run to pulleys
11:22 AM gloops: you will get 2000mm/min with 5mm ballscrews and coupled straight to nema 23
11:22 AM Cromaglious: my speed limit is my computer... piss poor step genrates
11:22 AM Louis_Cypher: Good point gloops
11:23 AM gloops: anyway making teA
11:23 AM Louis_Cypher: Seams you are british ;-)
11:23 AM Cromaglious: better than that using 5.08mm (.200" ballscrew)
11:24 AM Louis_Cypher: @gloops: great.
11:24 AM Louis_Cypher: Thanks
11:24 AM Louis_Cypher: The I will give the double screw setup a try
11:25 AM Louis_Cypher: Maybe I do start with my single motor and check whether it does loose steps
11:26 AM Cromaglious: look at around 4minute mark https://www.youtube.com/watch?v=-XS9o2lHqiU you can hear the ballscrew slapping around a bit.. it's bent a bit
11:27 AM Cromaglious: at the end it's moving 7700mm/m
11:28 AM Louis_Cypher: Is it fixed on both ends?
11:28 AM Louis_Cypher: Mine is much longer
11:28 AM Cromaglious: 0.200" ballscrew just over 8" of travel
11:28 AM Louis_Cypher: Maybe I should be more cautios
11:28 AM Cromaglious: just fixed at left side
11:28 AM Louis_Cypher: Ouch
11:29 AM Louis_Cypher: Mine is fixed on both ends
11:29 AM Cromaglious: 1500rpm max at 5.1"/s
11:30 AM IchGucksLive: good evening from germany
11:30 AM Cromaglious: I just need a straight screw, one end is fine for my short ass screw
11:30 AM Louis_Cypher: OK, that's aroung 7.5m a minute
11:30 AM Cromaglious: 7,7M/m
11:30 AM Louis_Cypher: I was calculating for my screw
11:31 AM gloops: at the end of the travel is that noise the screw?
11:31 AM IchGucksLive: Louis_Cypher: 12m/min is max on steppers
11:31 AM Louis_Cypher: Depends on screw, right?
11:32 AM Cromaglious: a bit, slop in the saddle is a bit
11:32 AM IchGucksLive: Louis_Cypher: The Setup itself
11:32 AM fragalot: IchGucksLive: good evening TO germany.
11:32 AM IchGucksLive: as i read 1600steps so 1/8micro
11:32 AM Louis_Cypher: LImited by what?
11:32 AM IchGucksLive: WHY
11:32 AM gloops: i shimmed by ballnuts pretty carefully, i noticed they are very sensitive to being twisted at all, makes a big difference how free they turn
11:33 AM IchGucksLive: Louis_Cypher: on 5mm Ballscrew Best Speed Best Torque best acuracy can be reatched BY
11:33 AM gloops: i made shims from a steel measuring tape
11:33 AM Loetmichel: *hrhr* interesting what details the "pro" eye notices... I just watched a late night show with some band playing in it... zoom on the singer: "ah, neutrik xlr." Zoom on the keyboarder: "more neutriks" camera pans over the mixer: only neutriks there, too... "they must have plenty of money at BBC, not a sigle switchcraft or similar crap!" ;)
11:33 AM IchGucksLive: Louis_Cypher: 400/turn Motor 20/25=1,25I Timingbelt at 0,01mm/step
11:33 AM Louis_Cypher: Did anyone experience inaccuracies due to excentric pulleys using a geared setup?
11:34 AM IchGucksLive: Louis_Cypher: where in the world are you
11:34 AM Louis_Cypher: Germany
11:34 AM IchGucksLive: Dann gehts auch in deutsch
11:34 AM Cromaglious: I'm almost thinking of making a hemijoint typ ballnut mount, 0 axial movement, x amount of radial and pitch
11:34 AM IchGucksLive: Louis_Cypher: drück mal doppelt auf meine namen
11:36 AM gloops: you could straighten the screw in a lathe or on some v blocks
11:36 AM Cromaglious: Loetmichel: yep, I've been screwed by bad cables at too many shows, I really hate it when gardeners cut out cables using string trimmers... (Outdoor shakespeare shows)
11:37 AM Cromaglious: s/cout out/cut our/
11:38 AM Loetmichel: Cromaglious: the belden cables we used 20 years back when i was in the business would have stood up to the nylon trimers.
11:38 AM Loetmichel: they were pretty much indestructible
11:38 AM fragalot: Loetmichel: you'd imagine they want things to be reliable at the bbc
11:39 AM fragalot: cheap gets expensive on live performances
11:39 AM Loetmichel: fragalot: i think so, yes
11:39 AM Loetmichel: its just interesting what catches the eye. even after all those years out of the business
11:40 AM Loetmichel: couldnt even tell you what band had played there... but the tech catched my attention ;)
11:42 AM Cromaglious: heh... I was a tire jockey (tire changer at tire shop) 40 years ago... I was overr at the tire shop getting a rim swapped out and I was pointing out mistakes (I was only customer there) and showing efficeincies.
11:42 AM fragalot: Loetmichel: I know the feeling :-)
11:42 AM Cromaglious: Loetmichel: same way on bands... Local crew 25 years ago...
11:43 AM Cromaglious: Time to replace my swiss seat and beeners...
11:43 AM Loetmichel: Cromaglious: yes, i am pretty annoying when going to get my car worked on while i stand beside it, too... :-)
11:44 AM Cromaglious: I have to climb a radio tower in a while
11:45 AM Loetmichel: Cromaglious: remove the main fuses of the transmitter and put them in your pocket... had my share of idiots to prove that to be a wise idea ;)
11:45 AM Loetmichel: (... and on a warships radar, not radio) ;)
11:45 AM Cromaglious: yep, throwing the breakers and locking the panel
11:47 AM fragalot: Loetmichel: isn't that why they invented keelhauling?
11:47 AM Cromaglious: only thing alowed plugged in is the router that we are aiming the panel attenna for
11:48 AM Loetmichel: fragalot: nott looked at that brightly when its your sergenant that you keelhaul... even if he earned it ;)
11:48 AM Cromaglious: and blanket parties
11:48 AM Loetmichel: (no idea what that is in american navvy. i was a "gefreiter" he was a "stabsbootsmann")
11:49 AM jesseg: Anyone ever tried these guys out? https://www.ebay.com/itm/121792648966
11:49 AM Cromaglious: jesseg: yes I have three
11:50 AM jesseg: Cromaglious, wow cool tell me more! Been happy?
11:50 AM Cromaglious: https://www.youtube.com/watch?v=S28XDMUmnNc
11:51 AM Cromaglious: jesseg: estatic! I now have 11 of their closed loop stepper
11:51 AM jesseg: wow cool!
11:51 AM fragalot: interesting setup
11:52 AM jesseg: Looks like you're cutting out the motor mount with the motor it's gonna mount
11:52 AM Cromaglious: yep
11:52 AM jesseg: well super cool
11:53 AM Cromaglious: go to my channel and watch the X2 at 5.1 in/s video, that's the iHSS60-36-30 (NEMA24 425oz in) motors
11:53 AM Cromaglious: using a carbide wood router bit
11:54 AM Cromaglious: on the mount cutting
11:54 AM jesseg: cool
11:54 AM jesseg: How do you detect following error?
11:56 AM Cromaglious: I need to wire up the alarm so I can estop on alarm. following error allowance is set with a tuner.
11:56 AM jesseg: cool
11:56 AM Cromaglious: if you get beyond the allowance it'll alarm and stop
11:57 AM Cromaglious: then you have to power cycle the drive
11:57 AM jesseg: naturally
11:57 AM Cromaglious: and rehome it
11:57 AM jesseg: I guess that makes sense
12:00 PM Cromaglious: on open loop stepper, you have no way of knowing when you have lost a step
12:00 PM jesseg: yeah that's why I patently hate steppers :P
12:00 PM Cromaglious: the drives also have a PED signal... On station, it changes state.
12:01 PM jesseg: In fact, a number of years ago, before it was popular, I built a prototype closed loop stepper by hacking on an encoder and writing firmware for a PIC
12:02 PM jesseg: What's a PED signal?
12:03 PM Cromaglious: that's the way I was going to go, then I saw clearpath, then I found JMC-motor a more reasonable solution. cheapest clearpath $257, Jmc-motor $115
12:05 PM Cromaglious: JMC's are coming down in price.
12:06 PM Cromaglious: PED is on station, when the motor is all caught up and following error is currently 0, PED changes state
12:07 PM Cromaglious: ALM changes state when following error is outside of allowed amount
12:07 PM Cromaglious: and motor stops
12:08 PM Cromaglious: bbiaw, getting a cuppa and have my morning ciggy butt
12:09 PM gloops: well, closed loop stepper sounds better, but what is the advantage really?
12:10 PM gloops: for high precision work, you miss steps, either it throws a full stop, or it regains the steps
12:10 PM malcom2073: If you're near the limits of your machine design, you'll know if you missed a step
12:10 PM malcom2073: If you oversize your steppers so it's not an issue, there's no real advantage
12:10 PM IchGucksLive: d3z1b3l: bist du da
12:10 PM gloops: yes you should match steppers to the load, naturally everyone ignores that and tries to get more and more out of a stepper
12:11 PM gloops: closed loop might regain the steps - but that could already be too late for close tolerance work
12:12 PM IchGucksLive: gloops: you can stop the g-code imedatly on los
12:12 PM IchGucksLive: and regain on green
12:13 PM IchGucksLive: i use halui pause
12:14 PM gloops: if youre watching Ichs
12:14 PM Cromaglious_: gloops: you can track PED signal for close tollerance
12:15 PM gloops: how many steps can it lose before reacting?
12:15 PM malcom2073: I would assume, if it microsteps, that it would know before it lost a step
12:15 PM malcom2073: if it starts to fall behind before getting a full step off
12:15 PM Cromaglious_: gloops software definable
12:16 PM gloops: well, i should get those then heh
12:17 PM fragalot: Cromaglious_: it's a 1000/rev encoder
12:17 PM fragalot: so let's say it needs 2 edges of that to track where it should be
12:18 PM fragalot: then that's the best accuracy it has to work with :)
12:19 PM gloops: we saw someone in here who used closed loop, but not connected to software, the machine made a massive error, which it then regained, but job was already lost
12:21 PM fragalot: even when you get an error, depending on the job it could either be fine, or lost
12:21 PM fragalot: if you're working down to tenths it's down the drain anyhow
12:22 PM fragalot: even if you're running true closed loop (eg. from linuxcnc directly)
12:24 PM gregcnc_: gloops i think that massive error was due to using default error setting
12:24 PM gregcnc_: which happened to be gigantic
12:25 PM gloops: gregcnc the one im thinking off, he didnt clamp the job properly, - large sheet of wood, the wood was lifting above the cutting length of the tool
12:26 PM gregcnc_: yes he pops in here when he runs into troubles
12:26 PM fragalot: I'm now curious what the error setting on mine is
12:26 PM fragalot: and how to actually set it
12:26 PM gregcnc_: you have to check how much error the drive allows before it faults.
12:26 PM fragalot: (they did not come with any form of usable manual)
12:26 PM gregcnc_: some are adjustable some are fixed
12:26 PM gloops: right i understand now gregcnc
12:26 PM gloops: i am only being contrary to try and learn about this stuff - honest lol
12:27 PM Cromaglious_: letting it run 8" + 5.1in/s 12in/s/s accell
12:28 PM fragalot: Right.. forgot it had an RS485 serial connection, lol.. that'l work to change the settings
12:28 PM gloops: most of the closed loop are stronger than typical nema23s anyway, which is a good start
12:29 PM gregcnc_: IMO closed loop stepper drives really only prevent cumulative lost steps. if a few steps scraps a part, it won't help.
12:30 PM fragalot: ^
12:31 PM gloops: http://www.zappautomation.co.uk/es-mh342200-20nm-holding-torque.html £840 for stepper driver and cable
12:34 PM gloops: similar debate over 2 motors on 1 axis versus single motor - what if one of the 2 motors loses steps? well what if the single motor loses steps?
12:35 PM Crom: you don't know until you rehome
12:35 PM fragalot: single motor loses step -> part fails
12:35 PM fragalot: dual motor and one loses steps continuously -> potentially warp gantry
12:35 PM fragalot: assuming you're using 2 of those 20Nm jobbo's
12:36 PM gloops: the outcome is the same if one of a pair loses, or a single loses anyway
12:36 PM fragalot: i'd rather scrap a part than tweak the machine frame
12:37 PM Crom: if you track PED, you don't have that worry
12:38 PM IchGucksLive: gloops: you are about to overshoot
12:38 PM fragalot: that said, even a single motor can tweak a frame, as I learned... 12 years ago?
12:39 PM IchGucksLive: 20Nm will kill your Balklscrew including Beariuing on Block
12:39 PM fragalot: 6Nm motor on an M10 leadscrew, accidental rapid before I properly set up the limit switches :P
12:39 PM Crom: I'll have to configure the MESA 7i92M to read the 2nd port for PED and ALM
12:40 PM fragalot: rather than | | the frame ended up / /
12:40 PM gloops: a dual motor axis can lose steps on one side for the same reason a single does, cutter at far side, hits something - lost step on that screw
12:40 PM fragalot: gloops: you mean if the coupler slips
12:40 PM fragalot: then yeah, you're right
12:40 PM fragalot: IchGucksLive: get a bigger ballscrew :P
12:40 PM gloops: the gantry can rack unless its totally rigid
12:41 PM Crom: the frame goes from || to = heh
12:41 PM IchGucksLive: gloops: on that price i woudt go the Pinion way
12:41 PM Louis_Cypher: Have to leave in an urge. THanks a lot guys!
12:41 PM IchGucksLive: with highend gears at 120Euros and 4Nm you get 45Nm
12:42 PM IchGucksLive: at les then halv the costs
12:42 PM gloops: Ichs i wont be buying servos, not yet
12:42 PM IchGucksLive: Hybrid is not servo
12:42 PM gloops: its servo prices lol
12:42 PM IchGucksLive: its a Fake
12:42 PM IchGucksLive: but better then TB6560
12:43 PM gregcnc_: no encoder?
12:43 PM IchGucksLive: Hybrid also no encoder to LCNC
12:44 PM IchGucksLive: if then 7i77
12:44 PM IchGucksLive: im off GN(
12:44 PM IchGucksLive: 8
12:44 PM Crom: I'm looking at all these servo's and they are like 0.2Nm, to get back to 2Nm, you loose 10x the speed
12:45 PM gloops: i cant see me having any problems, its difficult to force the gantry to miss step by hand, and these are only 3nm motors
12:46 PM Crom: time to oil ways
12:46 PM fragalot: gloops: yeah you'll be fine
12:48 PM gloops: just some method of holding the bigger pulleys tight, ill sort something
12:52 PM fragalot: gloops: do your steppers have keys?
12:53 PM fragalot: https://www.youtube.com/watch?v=LNxa9ec3N9M
12:59 PM gloops: no keyways no, actually ive just though, i didnt have this trouble with my other chain drive router, with the sprockets, ill see what i did with the bushes i made to fit to the motors, think it was just bigger crews, like 5 or 6mm
01:00 PM fragalot: gloops: perhaps it's just a better fit on the shaft?
01:00 PM fragalot: gloops: sleeve the pulleys & press them on whilst warm.. then hope you never need to clock them :P
01:00 PM gloops: maybe, i cant remember now what they were like, still got them in the garage though
01:01 PM XXCoder: geez. investors is insane. one icea tea company rebrands as "long blockchain" and stock doubles
01:02 PM fragalot: XXCoder: invest heavily into ponzi coin
01:03 PM XXCoder: im sure it will EVENUALLY stabilize and have better utility. but right now im not buying any
01:03 PM fragalot: XXCoder: look up what ponzi means
01:03 PM fragalot: specifically the ponzi scheme
01:04 PM XXCoder: .. I know what it means.
01:05 PM XXCoder: in any case, its not ponzi. it's a bubble.
01:06 PM fragalot: ponzicoin was designed to be a ponzi scheme
01:06 PM fragalot: the rest is indeed just another bubble
01:07 PM XXCoder: theres new digital coin called ponzicoin?
01:07 PM XXCoder: geez lol
01:07 PM XXCoder: sounds super legit
01:07 PM fragalot: http://ponzicoin.co/home.html
01:08 PM fragalot: it was a joke coin that got out of hand
01:08 PM XXCoder: "We suggest shilling this coin heavily to your family and friends like a fucking sociopath."
01:10 PM fragalot: brilliant isn't it
01:10 PM XXCoder: "A: Yes, it's not a good crypto scam if it doesn't involve pre-mined coins. I have pre-mined 200 PonziCoins for testing purposes and also because I like money."
01:10 PM XXCoder: lol
01:11 PM fragalot: the Q&A section is brilliant isn't it
01:11 PM XXCoder: yep
01:11 PM XXCoder: well off for naop later
03:30 PM robi: new ASS roter got ere
03:31 PM gloops: photos?
03:32 PM Cromaglious__: ASUS routerAC3100
03:33 PM gloops: oh, a router
03:37 PM gloops: there is not much mystery left in the 3 axis machine for me, although there is still plenty i need to know about them
03:38 PM fragalot: 3.1 :P
03:38 PM fragalot: (since you use 2 Y motors)
03:38 PM gloops: it will be some time off and i have a lot of other things to think about, but just at the back of my mind some new interest is slowly forming in a more advanced design
03:38 PM fragalot: already?
03:38 PM gloops: well i call the long axis X fragalot
03:39 PM fragalot: what do you have in mind?
03:39 PM fragalot: gloops: fair.
03:39 PM gloops: im not sure, something with rotary
03:41 PM fragalot: I could do with some rotissery tomorrow
03:41 PM gloops: i suppose it inflicts some who make machines, its never over, theres always the next one
03:41 PM gloops: hog roast?
03:42 PM fragalot: ribs
03:42 PM fragalot: chicken
03:42 PM fragalot: the works
03:42 PM gloops: any pork?
03:44 PM fragalot: not if there are ribs around
03:45 PM fragalot: I finally got around to making little collars for my press plates
03:45 PM fragalot: so I can stop dropping the damn 9kg beasts all the time
03:54 PM Cromaglious_: Am I back?
03:54 PM fragalot: yes
04:02 PM Deejay: gn8
04:20 PM gloops: someone on facebook asking for cam developers, university student needs to write cam software
04:22 PM CaptHindsight: do my homework for me?
04:22 PM CaptHindsight: there are a bunch of papers on it he could use and copy
04:24 PM gloops: i told him to come here dont know if he will
04:45 PM Petross404: How do you solve the missing rpc/rpc.h?
04:46 PM Petross404: I have this problem : https://forums.gentoo.org/viewtopic-t-1076454.html
05:26 PM JT-Shop: you use debian
05:32 PM Petross404: I am using gentoo
05:32 PM Petross404: I try to compile it with success

09:08 PM Tom_L:
09:09 PM malcom2073: trippy
09:11 PM malcom2073: I picked up yet another car today, more projects.
09:12 PM laminae: jthornton: went with the gecko drivers, i'm a bit out of my depth looking at spindles
09:14 PM laminae: The build documentation suggests a dewalt 611 but looking at people that do significant amounts of alum i'm going to want cooling, air pressure and suction
09:14 PM laminae: And i want my controller to manage speed
09:15 PM laminae: I'm tempted to just get the dewalt because it works and build up the rest on the side but again, kinda lost
09:15 PM laminae: Side note, anyone feel free to chime in
09:25 PM roycroft: you're building a cnc router, laminae?
09:25 PM laminae: Yep
09:25 PM roycroft: i'm in the middle of a wood router table build
09:26 PM roycroft: i've been using a porter-cable 7518 motor for router tables for the past 30 years or so
09:26 PM laminae: All about the craftiness
09:26 PM roycroft: but for this table i decided to get one of the 80mm chinese spindles
09:26 PM laminae: I've done a lot of 3d printing and laser cutting
09:26 PM laminae: but cnc router is new
09:26 PM roycroft: i wanted to be able to adjust the speed easily
09:27 PM roycroft: but a major reason for the spindle is that it is so much quieter than a router motor
09:27 PM roycroft: like 6x quieter
09:27 PM roycroft: also, i got a water-cooled spindle
09:27 PM roycroft: with a router table the cooling fan for the motor blows chips all over the place
09:28 PM roycroft: a water-cooled spindle has no cooling fan
09:28 PM roycroft: i'm not going to suggest you get one of those spindles
09:28 PM roycroft: just sharing my decision making process
09:28 PM roycroft: quiet and unmessy are big considerations for me
09:29 PM roycroft: https://www.amazon.com/gp/product/B011971H90/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1
09:29 PM roycroft: that spindle
09:30 PM roycroft: https://www.amazon.com/gp/product/B00Z4ZKXP8/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
09:30 PM roycroft: and that vfd
09:30 PM roycroft: together they cost about as much as a porter-cable 7518 motor
09:30 PM roycroft: lots of folks control that vfd with linuxcnc
09:32 PM roycroft: you can find brackets for the 80mm spindles all over the place on ebay if you don't feel inclined to make one yourself
09:35 PM laminae: I was also planning on having a vac and mister combo
09:36 PM laminae: How are you intending to control speed?
09:36 PM roycroft: there are air-cooled spindles that cost a bit less
09:36 PM roycroft: i will control the speed with the vfd
09:36 PM roycroft: i have a remote panel for it with a potentiometer on it
09:37 PM roycroft: but this is a manually operated router table
09:37 PM roycroft: you would control the speed with your cnc controller
09:37 PM laminae: Assuming you're outside of the states?
09:37 PM roycroft: i'm in oregon
09:37 PM laminae: Me too actually >.> that's a 220v spindle
09:37 PM roycroft: yes
09:37 PM roycroft: it's a 3 phase spindle
09:38 PM roycroft: the vfd takes single phase 240vac in and outputs 220vac 3 phase
09:38 PM roycroft: the vfd can also take 3 phase in
09:38 PM roycroft: it doesn't care
09:39 PM laminae: Assumiong you're voltage source is already wired that way?
09:39 PM roycroft: i have 240vac circuits in my shop
09:39 PM roycroft: i don't know how powerful a spindle you need
09:39 PM laminae: Unfortunately i do not
09:39 PM roycroft: mine is 2.2kw (3hp)
09:40 PM laminae: 110v standard wall
09:40 PM roycroft: if your need is for a smaller one you can get a smaller vfd that takes 120ac in
09:40 PM laminae: 120*
09:40 PM emc: I just, JUST finished configuring a Huangyang 110v VFD to work work with LinuxCNC.
09:41 PM laminae: I would prefer to have my controller manage endmill speeds so i'll still have to find an option for that
09:41 PM laminae: How was that experience?
09:42 PM emc: agonizing until ecstasy
09:42 PM roycroft: it's pretty straightforward
09:42 PM laminae: I'm intending to use a 7i76e controller via ethernet to linuxcnc
09:42 PM emc: You are speaking my language....that's what I'm using.
09:42 PM roycroft: the vfd has analog inputs for frequency control
09:42 PM emc: I'm using the RS485 USB interface
09:43 PM emc: it works like a charm
09:43 PM roycroft: you can do that too
09:43 PM laminae: scooped up these drivers for ti: http://www.geckodrive.com/geckodrive-step-motor-drives/g251x.html
09:43 PM roycroft: i'm doing a cnc conversion of my mill/drill whenever i get around to finishing it
09:43 PM laminae: I'm going to wait a month, if the 7176 is still out of stock i'll have to find an alternative
09:43 PM roycroft: i'm using mesa hardware and gecko drives - i have all that stuff already
09:43 PM roycroft: i have stepper motors for it too
09:43 PM roycroft: and the computer
09:43 PM roycroft: all i need are the ball screws, and the time and ambition to actually do the conversion
09:44 PM laminae: Only thing i don't have is the mesa stuff ordered
09:44 PM laminae: Oh and psu
09:44 PM roycroft: jt, who lives on this channel, is an authorized mesa reseller
09:44 PM emc: I can't recommend that board highly enough. After fartzing around with 3 different parallel boards, it's like I jumped of a skateboard and onto superbike
09:44 PM roycroft: if you need mesa cards talk to him
09:44 PM roycroft: he usually goes by jt-shop
09:44 PM laminae: talk to who?
09:44 PM roycroft: jt
09:45 PM laminae: He seems to be here, probably AFK
09:45 PM roycroft: yes, it's saturday night
09:45 PM emc: Is he the guy behind mesaus.com?
09:45 PM roycroft: if he's smart he's hanging out with his wife
09:45 PM roycroft: yes
09:45 PM pink_vampire: hii every one
09:45 PM roycroft: it's dark in missouri, so i'm sure he's not hanging out with his chickens at the moment :)
09:45 PM laminae: THis is what i'm building on
09:45 PM laminae: http://openbuildspartstore.com/openbuilds-c-beam-machine-xlarge/
09:46 PM emc: He's the guy who got me rolling...just buying his pre-configured 2.8pre hard drive...worth every dime.
09:46 PM laminae: I would have liked something larger but i don't have the space and i'm moving within a year so i really didn't want to buy something that would be really hard to move
09:46 PM emc: I needed the dual motor y-axis, and I was chasing my tail trying to get LCNC wired up to drive it. I was going nuts.
09:46 PM emc: that purchase took a month off my build time.
09:47 PM pink_vampire: laminae: please avoid rails like that
09:48 PM laminae: Unfortunately it is too late for that
09:48 PM pink_vampire: how do I make the red switch click like the yellow one?? https://www.youtube.com/watch?v=y5U4axU0efY
09:48 PM laminae: You mean the y axis movement?
09:48 PM laminae: Or c beams in general?
09:49 PM roycroft: get another yellow one and paint it red?
09:49 PM pink_vampire: it is must be small
09:50 PM pink_vampire: 12mm diameter
09:50 PM pink_vampire: the hole diameter
09:50 PM roycroft: grind it down before you paint it
09:50 PM emc is now known as CNCZombie
09:51 PM pink_vampire: this is the inside https://i.imgur.com/pV3O4ow.jpg
09:51 PM laminae: that's a tactile vs push switch
09:51 PM CNCZombie: You just want it to have it go "thunk" when you press it"
09:51 PM CNCZombie: ?
09:52 PM pink_vampire: i want it to make the click sound
09:52 PM CNCZombie: I can think of several brutal kludge hacks
09:52 PM pink_vampire: like what?
09:53 PM pink_vampire: it is need to be strong
09:53 PM CNCZombie: the first of which is buy a 2nd red button, field strip it and fudge a mount for it underneath a shell of the yellow button -- with it's electrical guts removed.
09:54 PM pink_vampire: the yellow is 30mm hole diameter, and the red is 12mm
09:55 PM CNCZombie: right.
09:55 PM pink_vampire: i don't have very limited room where the reg go
09:56 PM CNCZombie: You'd have to create a bracket that holds the "guts" of yellow underneath the stipped-out red switch then create a sprung pushrod between them.
09:56 PM CNCZombie: that's a problem then.
09:57 PM roycroft: i would not go trying to modify an existing actuator
09:57 PM laminae: If that is push-to-make vs -push-to-break you could just swap the back shell for a 12mm threaded tactile switch
09:57 PM pink_vampire: i don't have a room for that
09:57 PM roycroft: you should be able to find a 12mm actuator with the specifications that you need
09:57 PM laminae: Assuming there isn't an illuminated led of something on ctontact
09:58 PM pink_vampire: https://www.ebay.com/itm/Durable-12V-12mm-Elevated-Car-Black-Button-Blue-Angel-Eye-LED-Momentary-Switch/332234465328?epid=910485606&hash=item4d5ab7a030:g:c5sAAOSwr6pZ8NYg
09:58 PM pink_vampire: this one look nice
09:58 PM CNCZombie: can you disassemble the red one and reasseble it non-destructively?
09:58 PM roycroft: make a nice cup of tea, pull out the allied and newark and mouser and digi-key catalogs, and spend some time perusing them
09:58 PM pink_vampire: but how do i know if it make the click feel?
09:59 PM laminae: Does it have a product code stamped on it?
09:59 PM pink_vampire: CNCZombie: I need a new switch, not to modify it
09:59 PM laminae: WOuld be easier to determine with a schematic diagram
09:59 PM laminae: Then we'd know what current it's rated for and the dimension specs, travel etc
10:01 PM CNCZombie: I've rebuilt vintage arcade games by kludging switch interfaces with new guts, so I'm very comfortable with it. It't not for everyone...but I was trying to keep original appearance, and some things just were available.
10:01 PM CNCZombie: were not available.
10:02 PM laminae: side note, can anyone suggest something better than this to run the 7i76? i'm only linking it because it was one of the hgher reviewed iptions on the known working hardware but that was quite some time ago https://www.gearbest.com/tv-box-mini-pc/pp_590406.html
10:02 PM roycroft: you want a momentary action tactile actuator
10:02 PM roycroft: "tactile" is the key word for the clicking bit
10:02 PM laminae: It's like there's an echo
10:03 PM pink_vampire: mmm
10:03 PM laminae: Knowing if your shell will fit what you order is the problem
10:04 PM laminae: And there aren't many pinned options like you are seeking so you won't have much selection
10:04 PM pink_vampire: it is need to be soft to press on it
10:04 PM laminae: Would be easier to find a suitbale sub if we had the datasheet for the one that currently fits
10:04 PM roycroft: i just got a atx system board with an atom processor and stuck it in a 3u rack mount chassis for my linuxcnc computer
10:05 PM roycroft: i got a mesa 5i25, which is why i needed the bigger enclosure
10:06 PM laminae: In a perfect world i'd like to atach the computer to the back of the montior so i can swing it in and out, but that is defintiely an option
10:06 PM CNCZombie: I have one of these, in use with the 7i76e: https://www.ebay.com/i/142670626280?chn=ps
10:06 PM CNCZombie: Upgraded to an SSD and maxxed the memory.
10:07 PM CNCZombie: It's nice to have a touchscreen
10:10 PM roycroft: i put an ssd i my linuxcnc machine
10:10 PM laminae: I think i have a spara sata sst
10:10 PM roycroft: i didn't want a hard drive in a shop environment
10:11 PM laminae: I like the idea of the touch screen a lot
10:11 PM roycroft: and i got a kiosk touchscreen for the machine
10:11 PM roycroft: it will be nice
10:11 PM roycroft: i'm going to build a custom control panel for the machine
10:11 PM roycroft: and the kiosk display will bolt right in
10:11 PM roycroft: i also got a stainless steel kiosk keyboard
10:17 PM laminae: That would take more space than i can really spare unfortunately
10:18 PM roycroft: yeah, sounds like you're tight on space
10:18 PM roycroft: i found an old roll-around 19" cart from some ibm system
10:19 PM roycroft: my plan is to put the linuxcnc machine in the rack, along with a box for the gecko drives, etc., and the power supply for the motors
10:19 PM roycroft: i have a 48vdc rack mount power supply
10:19 PM roycroft: the cart top is the perfect height to hold a console
10:20 PM roycroft: there will be a bit of extra room in the rack part of the cart
10:20 PM roycroft: since it's roll-around i might be able to use it for multiple cnc machines
10:20 PM roycroft: until i need to run more than one at a time
11:11 PM Connor: Added a Main Disconnect switch to the back of the VFD enclosure.. also got the X Axis power feed working.. Who ever re-assembled the mill prior to my ownership installed the bearings and the screw backwards. Suppose to have a fixed side (2 bearings) and a floating side. Fixed was suppose to be on the left, floating on the right.. Oops.. they had it backwards.. Not good when installing the power feed on the right hand side..
11:47 PM Cromaglious_: Anyone want 4 of the knockoff sonoff wifi modules?
