12:19 AM CaptHindsight: Tom_L: spindle encoders?
12:32 AM pink_vampire: CaptHindsight: for spindle I think you need much higher resolution.
01:23 AM diverdude: Does anybody know if this is the formula accelstepper is using to calculate acceleration ramps? https://www.embedded.com/design/mcus-processors-and-socs/4006438/Generate-stepper-motor-speed-profiles-in-real-time
01:26 AM diverdude: it seems so :)
01:59 AM Deejay: moin
02:25 AM selroc: hmmmmmm
02:25 AM selroc: log not working
02:27 AM selroc: no, only lagging
04:13 AM diverdude is now known as Guest3619
04:23 AM XXCoder: laggy loggy
04:26 AM veek: what's the difference between a 4 stroke 2 wheeler petrol engine and a tractor/tiller engine.. i was looking at some specs and the tiller has Displacement (Swept Volume) 631 cu.cm whereas the 2-wheeler has ngine Displ. : 87.8 cc but SUPPOSEDLY it produces 5 bhp of power at 6500 rpm and the tiller is rated at 9hp..
04:27 AM veek: the power's almost comparable but the displacement's hugely different
04:59 AM jthornton: morning
05:04 AM Tom_L: morning
05:07 AM Jin|away is now known as Jin^eLD
05:07 AM Jin^eLD: morning
05:21 AM Deejay: hey
07:17 AM Loetmichel: *MUHAHAHA* chinese people... Jist cracked open one of those cheap 5V2A SMPS... WHY?!? -> http://www.cyrom.org/palbum/main.php?g2_itemId=17198&g2_imageViewsIndex=1
07:21 AM jdh: why did you open it?
07:22 AM Loetmichel: it should go into a steel inclosure.. i think i get a different one out of the stash ;)
07:33 AM gregcnc: if it fits it ships
07:33 AM Rab: If it doesn't fit, make it!
07:34 AM Loetmichel: hmm, just open a second one... PCB mounted in the other enclosure shell.. PCB not bent.. but the rest looks equally bad... -> http://www.cyrom.org/palbum/main.php?g2_itemId=17201&g2_imageViewsIndex=1
07:34 AM Loetmichel: Rab: indeed!
07:36 AM Rab: Oh, I guess they forced it in backwards then?
07:37 AM Loetmichel: yes, looks like it
08:01 AM Loetmichel: well, it looks decent now at least... and works the job its supposed to... -> http://www.cyrom.org/palbum/main.php?g2_itemId=17204&g2_imageViewsIndex=1
09:25 AM Tom_L: Loetmichel but you voided the warranty by cracking it open !
09:26 AM Loetmichel: Tom_L:_ warranty? on cheap chinese PSUs?
09:26 AM Loetmichel: especially ones that were surplus from some Fiberoptic media converters we bought and used inside a PC
09:27 AM Tom_L: 100% satisfaction warranty lasts until they ship it
09:27 AM Loetmichel: indeed ;)
10:00 AM Spida: Loetmichel: fiberoptic media converter inside PC? why not use a fiber card?
10:01 AM Loetmichel: Spida: no free slot
10:01 AM Loetmichel: mini-itx board
10:02 AM Spida: ah
10:16 AM robotustra: question: does anybody know how to get tool path coordinates from interpreter of rs274ngc without execution the command?
10:19 AM cradek: I don't understand your question, can you say more?
10:20 AM robotustra: let say I open gcode file and give and I what to get the trajectory of the tool.
10:21 AM robotustra: rs274ngc interpreter can read and execute this code, but I would like to get a whole trajectory before execution to draw it in OpenGL view window
10:22 AM seb_kuzm1nsky is now known as seb_kuzminsky
10:22 AM robotustra: I didn't find a function which parse gcode file line by line and return the trajectory coordinates in the interpreter
10:23 AM robotustra: where I can get trajectroy coordinates from without actual running of the code?
10:24 AM cradek: are you aware that AXIS already does this exactly?
10:24 AM cradek: you could look at that, or perhaps you should look at the standalone interpreter, which is the program named rs274
10:26 AM robotustra: I read a doc about rs274ngc, but it has NO function to return position coordinates
10:27 AM cradek: but it prints the moves to stdout
10:27 AM robotustra: and I don't want to make my own interpreter of gcode because it's 1) too big (>12000 lines)
10:27 AM HighInBC: no need to interpret every line at once
10:28 AM robotustra: cradek, does it prints while execute?
10:28 AM robotustra: I want to draw trajectory BEFORE I execute a single line of code
10:29 AM cradek: do you know AXIS already does this?
10:29 AM hazzy-m: robotustra: https://github.com/KurtJacobson/Rockhopper/blob/master/GCodeReader.py#L134
10:29 AM robotustra: it does it in python. I would like to do it in c++
10:30 AM robotustra: I need c/c++ api to do this
10:30 AM robotustra: not python
10:31 AM hazzy-m: Look at how the python implementation does it, that will at least give you an idea of what you need to do in c++
10:31 AM robotustra: If I can just call interpreter line by line and get all coordinates without actual execution it wil be ok
10:32 AM HighInBC: is there a "dry run" mode?
10:32 AM robotustra: I already have an idea, I suspect that this c/c++ api already exist in the heap of the code
10:32 AM robotustra: HighInBC, where to look at this?
10:32 AM robotustra: probably
10:33 AM HighInBC: I dunno
10:36 AM robotustra: hazzy-m, it means that gcode reader reads only motion g-codes?
10:36 AM robotustra: like feed, arcfeed and traverse?
10:38 AM hazzy-m: No, it reads all the lines, there are also dwel, toolchange, rotaryindex and others, can't remember the exact names, its been a while since I played with it
10:40 AM robotustra: wait a minute, it looks like interpter can do either execution of just printing of information
10:40 AM robotustra: Igo back to reading
10:40 AM hazzy-m: That python code is using the python interface for the rs274 interpreter, so if you look at how that is implemented you should have a very good I idea what you need to do
10:41 AM hazzy-m: Yes, you can use it just to spit out info
10:41 AM robotustra: hazzy-m, why I should read python code if there is original interpreter written in c++ code + it's well documented?
10:42 AM robotustra: and I'm going to use c/c++ api directly
10:43 AM robotustra: python is smoking aside, I don't want to touch python even with 10 ft stick. :)
10:43 AM hazzy-m: reading the python code might give you a hint as how you can use the interpreter ...
10:44 AM robotustra: how to use interpreter is written in the document in English
10:44 AM robotustra: https://ws680.nist.gov/publication/get_pdf.cfm?pub_id=823374
10:46 AM robotustra: I have to read "stand alone interpreter" chapter
10:46 AM robotustra: thanks
11:09 AM JT-Shop: I wonder how that got lost from the current documents
11:14 AM fragalot: hi
11:33 AM miss0r: hey
11:33 AM miss0r: last seen miss0r
11:33 AM miss0r: seen miss0r
11:33 AM miss0r: !seen miss0r
11:33 AM miss0r: ?
11:36 AM miss0r: is the bot broken?
11:42 AM Rab: 06:32 -!- miss0r|office [~miss0r@] has quit [Ping timeout: 246 seconds]
11:43 AM Rab: 06:33 -!- miss0r [~miss0r@] has quit [Ping timeout: 252 seconds]
11:43 AM miss0r: Yeah, we had a poweroutage at some point. What is your timezone?
11:43 AM Rab: (11:42 Texas time - 06:33 = 5 hours 9 minutes ago)
11:43 AM miss0r: Great. Thanks :)
11:43 AM Rab: np
11:45 AM fragalot: miss0r: I think it was .seen, but the bot is indeed gone
11:45 AM fragalot: also - my DRO has just shipped
11:46 AM miss0r: :o Exciting news! :D
11:47 AM JT-Shop: fragalot: got your code in my program and it works perfect, thanks
11:50 AM miss0r: fragalot: Have you started picturing it for your inner eye? :)
11:50 AM fragalot: JT-Shop: glad it works :D
11:51 AM fragalot: miss0r: My inner eye?
11:51 AM miss0r: isn't that a term? :D
11:51 AM fragalot: no :P
11:51 AM miss0r: :D
11:51 AM fragalot: miss0r: what i've mostly been wondering is how the hell i'm going to rigidly mount the read head on the Y given that there's no real flat surface..
11:51 AM miss0r: its like imagining pictures in your head.
11:51 AM fragalot: on the RF45 I made a subplate with 3 setscrews to align it
11:51 AM fragalot: but i'm not sure if I want to go that route again
11:52 AM miss0r: fragalot: Didn't we somehow cover this on the video tour?
11:52 AM miss0r: I can't remember the conclusion
11:52 AM fragalot: miss0r: we only covered position :P
11:52 AM miss0r: I'd need another tour or extensive amounts of pictures
11:53 AM fragalot: miss0r: https://media.exapro.com/product/2016/05/P60503105/1ae93fe53814ae9bab524ed25fe06340/schaublin-13-vertical-milling-machine-p60503105_4.jpg
11:54 AM fragalot: the proper place to put it would be on the right of that clamp
11:54 AM miss0r: yeah. that is what we talked about, yeah
11:55 AM fragalot: so the rail is easy.. just use that brown strip that's perfectly square to mount it
11:55 AM miss0r: I would probally make a block of steel with two bolts to attack it, and three set screws; two at the bottom & one at the top
11:55 AM fragalot: so the same way I did it on the RF45 then
11:55 AM miss0r: for ajustment
11:55 AM miss0r: basically, yeah
11:55 AM fragalot: I guess it did work well, and i'm expecting less than 1cm of bondo on this machine :P
11:56 AM miss0r: bondo?
11:57 AM fragalot: body filler
11:57 AM miss0r: hehe
11:57 AM miss0r: the RF45 was basically bodyfiller with some cast iron reinforcements inside :D
11:57 AM fragalot: I played around with a euromac FX punch today
11:58 AM fragalot: blimmin' nice machine, that
11:58 AM miss0r: hehe :D
11:58 AM miss0r: I fell in love with a small okuma CNC lathe today :-/
11:58 AM miss0r: it *only* has a footprint the size of my maho
11:59 AM miss0r: alas... impossible love
11:59 AM fragalot: xD
11:59 AM miss0r: but it was just so damn cheap!
11:59 AM fragalot: ZX, not FX*
11:59 AM fragalot: miss0r: until you add the Schunk chuck
12:00 PM miss0r: it already came with a röhm chuck. both 3 and 4 jaw
12:00 PM fragalot: no comparison
12:00 PM miss0r: rotary tools damnit !
12:01 PM miss0r: two x rotary tools
12:01 PM fragalot: just enough to make you realize what you're missing
12:01 PM fragalot: :D
12:02 PM miss0r: :'( *sob*
12:02 PM fragalot: CNC lathes only really get interesting once you start with 8 axis machines
12:02 PM miss0r: if I had the room to fit it, I would've bought it on the spot
12:02 PM fragalot: quicktech has some really neat affordable compact ones that i've run in the past
12:02 PM miss0r: nah. I would be pretty happy to own a two axis cnc
12:03 PM miss0r: This was an okuma Space Turn LB something. They only wanted 8k eur for it
12:03 PM fragalot: pocket change
12:03 PM miss0r: I'm not quite over it yet...
12:03 PM fragalot: xD
12:04 PM miss0r: Reality kicked in, and told me I had to turn it down
12:04 PM fragalot: so. no GLS delivery note yet
12:04 PM miss0r: the tracking info still says it is in Denmark...
12:04 PM miss0r: Tomorrow I will call them and tear them a new one
12:04 PM * fragalot nod
12:05 PM fragalot: speaking of tearing a new one
12:05 PM fragalot: do you know where I could get some covers for my Z ways
12:05 PM fragalot: I tried using a rubber flap but with the way the Y moves that's just no good
12:05 PM miss0r: Can you do me a favour, and go put 22ish screws in a piece of wood, and take them out again, so I do not feel I've put all those screws in for no reason ? :)
12:06 PM miss0r: what are you thinking? harmonica ones?
12:06 PM fragalot: either harmonica, or stainless ( ones that overlap like the original
12:07 PM fragalot: er, like the deckels
12:07 PM fragalot: i'm not sure if schaublin ever bothered with way covers
12:08 PM fragalot: at least there's certainly zero provision for it
12:08 PM miss0r: hmm.. Looking, one sec. But if I can find it, it will be at a danish seller. And our luck with shipment isn't realy that great
12:09 PM fragalot: also - I think my whim purchase of a tschorn 3D taster may have been optimistic
12:09 PM miss0r: You should've gone for haimer :)
12:09 PM fragalot: because the table has to be all the way down and it /BARELY/ clears the vise xD
12:09 PM miss0r: :D
12:10 PM fragalot: I wish I could 've found a direct BT30 one that wasn't €600
12:10 PM miss0r: fragalot: https://industrikomponenter.dk/
12:10 PM miss0r: Its all in danish :D but they got what you need
12:10 PM miss0r: https://industrikomponenter.dk/produkter/maskinbeskyttelse/
12:11 PM miss0r: 1) http://industrikomponenter.dk/wp-content/uploads/2017/02/teleskopafdaekning.pdf
12:11 PM fragalot: i'm wondering how the hell I can actually mount bellows correctly
12:11 PM miss0r: 2) http://industrikomponenter.dk/wp-content/uploads/2017/02/foldebaelge.pdf
12:11 PM fragalot: the fact that the Y is on top of the machine, and the XY assembly moves sideways does not make it straightforward
12:12 PM miss0r: Nope. I guess you'll just have to clean it often :D
12:12 PM fragalot: :D
12:13 PM miss0r: Mill alot of cast iron with & use the airgun often. Then you will be forced to clean it :D Easy
12:13 PM fragalot: :P
12:14 PM miss0r: Nice, they also have leadscrew covers: http://industrikomponenter.dk/wp-content/uploads/2017/01/teleskopfjedre.pdf
12:14 PM fragalot: I also need to make a pan for it
12:14 PM miss0r: I did not know that
12:14 PM fragalot: because flood coolant atm is ... well, a mess.
12:14 PM miss0r: That comes as a surprise :P
12:14 PM fragalot: and a huge waste as 80% of it goes on the floor
12:15 PM fragalot: (it runs down the vertical Y table slots, onto the Z handwheel & floor on both sides of the machine)
12:15 PM miss0r: That sounds less than ideal
12:16 PM fragalot: Quite.
12:17 PM miss0r: https://9gag.com/gag/aN1x9Zr danish commercial. :)
12:18 PM miss0r: "vegan alert" :D
12:18 PM fragalot: ha
12:18 PM fragalot: I like the pet name he's got
12:18 PM miss0r: "Skattebasse" ?
12:18 PM fragalot: because if you interpret it in flemmish it means "fart berry"
12:19 PM miss0r: hehe
12:19 PM miss0r: Its basically 'sweet heart'
12:19 PM fragalot: (and yes we actually use that as an endearing term sometimes tooà
12:19 PM miss0r: haha, of course you do :D
12:23 PM miss0r: I have an issue with a machine I am working on. It mixes air into the oil, almost making it foamy
12:23 PM miss0r: reasonable deduction; air is getting into the system. And because it is a medium pressure system, it must get in there before the pump.
12:23 PM fragalot: use an oil that doesn't have a saponifier in it
12:24 PM miss0r: Well, by the time the oil gets back to the resevoir, its returned to its clear state
12:25 PM miss0r: before the pump theres a pipe going into the resevoir, through a filter & into the pump. and I cannot for the life of me find a hole or bad joint ! :-/
12:26 PM miss0r: Its not a real issue, as the oil is still quite viscous(?) & lubricates like it is supposed to. It just looks wrong
12:26 PM miss0r: it probably pisses me off more than it should :]
12:27 PM fragalot: :P
12:28 PM fragalot: I wonder if I could abuse my saline content refractometer for coolant
12:28 PM fragalot: :P
12:28 PM miss0r: you can
12:29 PM miss0r: but it needs the right scale in there for it to make sense :)
12:29 PM fragalot: relative measurement is fine for me :P
12:29 PM fragalot: mix 'known good' amount, read it's ... salinity ... and use tha as a baseline
12:29 PM * fragalot will try this
12:48 PM -!- #linuxcnc mode set to +v by ChanServ
12:57 PM miss0r: fragalot: A friend of mine just dumped three raaco drawer systems off
12:57 PM miss0r: The small ones... :) but still, where does he expect I can fit that ? :D
12:57 PM fragalot: kitchen
12:58 PM miss0r: We actualy have a very small kitchen :D so not
12:59 PM fragalot: office
12:59 PM fragalot: livingroom
12:59 PM fragalot: car
12:59 PM miss0r: Quite likely where they will end up(office)
12:59 PM miss0r: hehe car.. Not a good idea to have non lockable drawers in a car..
01:00 PM fragalot: easy fix
01:00 PM miss0r: I also would like to be able to access it *sometimes* -> less easy fix than what you were thinking about :P
01:01 PM fragalot: I was just thinking a simple pin & 2 washers
01:01 PM fragalot: slide pin in, all drawers locked.. remove pin, all drawers open
01:01 PM miss0r: okay - that is pretty easy. But still a minimum of 4 per drawer system
01:02 PM miss0r: four columns of drawers.
01:02 PM fragalot: or 2 if you use a wide strip
01:03 PM miss0r: huhm.. Not a bad idea actualy. You know I hate to give it to you :D
01:03 PM fragalot: :P
01:06 PM miss0r: my wrist watch just fell into 9 pieces.. wtf
01:07 PM miss0r: the band broke off and the watch fell to the ground sheering two additional pieces off the band + alot of loose pins
01:07 PM fragalot: oops
01:08 PM miss0r: It had it at the watch repair man last week to have the pins checked!
01:08 PM miss0r: I felt they were getting loose, and he told me they were fine and not worry about it !
01:08 PM miss0r: bah!
01:08 PM miss0r: He thought he would get this repair job :D but jokes on him, I'll take the next one down the road
01:46 PM gregcnc: interesting two speed belt drive for mill spindle https://www.instagram.com/p/Bn4JWudgR2f/
01:59 PM fragalot: gregcnc: looks like a great way to wear them out :P
01:59 PM gregcnc: flat spots
02:44 PM syyl: as far as I know he has a plan to completely get them free of the pulley when not in use
02:45 PM Jin^eLD: if gmocappy hangs, what would be the way to see why or to debug it?
03:15 PM Tom_L: gregcnc, rig up 2 AC compressor clutches
03:15 PM Tom_L: one for each side
03:16 PM Tom_L: or something similar
03:55 PM Deejay: gn8
04:09 PM pink_vampire: i need help with feed and speed for drilling
04:11 PM Tom_L: material?
04:11 PM pink_vampire: 2024-t3
04:12 PM Tom_L: https://www.chipblaster.com/high-pressure-drilling-speeds-feeds-aluminum
04:12 PM Tom_L: wait.. that's not for drills
04:13 PM Tom_L: http://www.morsecuttingtools.com/Technical%20Data/HSS%20&%20Cobalt%20Drill%20Speed_Feed.pdf
04:13 PM pink_vampire: problem #2 where is the tap & drill set???
04:13 PM Tom_L: what do you mean?
04:14 PM Tom_L: depends how you program them
04:14 PM pink_vampire: i can't find my tapping set
04:14 PM Tom_L: set to the point and add .3 * diameter for the point
04:17 PM pink_vampire: i want to see what drill diameter i need, but i need to find the tapping set first.
04:18 PM pink_vampire: ok, found it!
04:18 PM Tom_L: the .3 is for a 118 deg point
04:18 PM Tom_L: also depends on the type of tap
04:18 PM pink_vampire: the screw is 8-32, and the drill is #29
04:18 PM Tom_L: high helix is recomended for cnc
04:19 PM Tom_L: how deep?
04:19 PM pink_vampire: I'm going to tap by hand.
04:19 PM Tom_L: wtf for?
04:19 PM pink_vampire: i only need to drill it
04:19 PM Tom_L: you got linuxcnc for that !!
04:19 PM pink_vampire: for the servo spindle belt holder
04:20 PM Tom_L: for the drill depth figure the depth you want and add .3*diameter for the point
04:20 PM Tom_L: set the drill off the point like you would a mill cutter
04:20 PM pink_vampire: the hole depth is 25mm
04:20 PM Tom_L: 1"
04:21 PM Tom_L: no tap will tap that deep
04:21 PM Tom_L: not that size
04:21 PM pink_vampire: the tapping is 3/4" deep
04:21 PM Tom_L: so peck drill the hole
04:21 PM pink_vampire: but how do i drill it?
04:22 PM Tom_L: what do you mean?
04:22 PM Tom_L: G83
04:23 PM pink_vampire: what rpm, Z feed, in what depth to peck it?
04:23 PM pink_vampire: the drill is hss
04:23 PM Tom_L: you can peck the drill diameter and be safe
04:23 PM Tom_L: 800-1000 rpm probably
04:23 PM Tom_L: figure your chip load from that
04:24 PM pink_vampire: I can't go that slow
04:24 PM Tom_L: minimum?
04:24 PM pink_vampire: 20K
04:24 PM Tom_L: good luck
04:24 PM Tom_L: make sure you spot the holes
04:24 PM pink_vampire: i can go up to 60K
04:24 PM Rab: With HSS?
04:25 PM pink_vampire: it will be almost like EDM
04:25 PM Rab: I mean, friction drilling is a thing...
04:25 PM Tom_L: 2024 is kinda gummy isn't it?
04:25 PM Tom_L: better run a test hole
04:25 PM pink_vampire: much harder then 6061
04:26 PM Rab: Are you using coolant?
04:26 PM pink_vampire: baby oil
04:26 PM Tom_L: i'd hope so if he's goin 1" deep
04:26 PM Tom_L: 25mm sry
04:27 PM Tom_L: you may end up burning up the drill at those speeds
04:27 PM Tom_L: i've never tried it with a high speed spindle
04:28 PM pink_vampire: at least is not titanium that can self ignite
04:28 PM Tom_L: you want .001 - .002" per revolution
04:29 PM Tom_L: so figure your minimum rpm ( it will have no torque at that speed )
04:29 PM Tom_L: and adjust your feed to that
04:29 PM Tom_L: use the drill diameter as the peck depth
04:29 PM Tom_L: approx
04:30 PM pink_vampire: i don't have 1/8" center drill on hands.
04:30 PM Tom_L: http://www.norsemandrill.com/feeds-speeds-drill.php
04:31 PM pink_vampire: i will use the tip of 1.6mm carbide drill as starter
04:31 PM Tom_L: you need to spot it or the drill will wander and break
04:31 PM Tom_L: better not be a drill from your 'crap' set either. use the good one :)
04:32 PM pink_vampire: the #29 is new from the box.
04:32 PM pink_vampire: and the 1.6mm is also new
04:32 PM Tom_L: from china, germany, sweeden or USA?
04:32 PM Tom_L: etc
04:33 PM pink_vampire: USA
04:33 PM infornography: I got some chinese centerdrills the other day and they break if you look at them sternly
04:34 PM infornography: no more china drills
04:36 PM pink_vampire: my probe is too big for my HF spindle :(((
04:36 PM pink_vampire: i'm using paper :(
04:39 PM Jin^eLD is now known as Jin|away
05:21 PM pink_vampire: chatteringggggggggggggggg
05:24 PM gloops: movingggggggg?
05:25 PM gloops: tool or work
05:26 PM pink_vampire: carbide tools are nice and solid, but hss in 60K, is like a string, it flex sooooooo much
05:27 PM pink_vampire: and i'm sure someone across the road also can hear the chattering noise from it
05:27 PM gloops: what is the operation/machine pink_vampire, i missed the convo
05:28 PM pink_vampire: so don't drill with 3.4mm hss drill at 60K rpm, it will make some noise
05:28 PM pink_vampire: gloops: i'm just trying to drill some aluminum
05:28 PM gloops: 60k rpm lol
05:29 PM Tom_L: a little ridiculous at best
05:29 PM gloops: not nt going to clear chips without fast feed? will just melt them
05:31 PM pink_vampire: gloops: the drill is flex like crazy
05:31 PM Tom_L: just don't pick the drill outta your eye when it snaps
05:33 PM pink_vampire: the drill is stick out about 3"
05:37 PM pink_vampire: 2 holes done 8 more to go
05:38 PM Tom_L: good you didn't decide to tap at 60k
05:40 PM pink_vampire: Tom_L: it will become a welded stud
05:42 PM pink_vampire: the pecking take time
05:48 PM pink_vampire: part fly from the vise
06:27 PM pink_vampire: Tom_L: I think i fount the best way of using the HF spindle,
06:29 PM CaptHindsight: started dissasembly of a Chinaco router, they used heat shrink along with a twist vs solder and shrink for the motor connections
06:29 PM pink_vampire: the penetration must be slow to get a good start in the center, then to crank up the spindle speed and about 10mm you can dust the material in 60K
06:30 PM pink_vampire: CaptHindsight: what is "Chinaco router"?
06:30 PM CaptHindsight: Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/encoder/encoder_batch.jpg spindle encoders?
06:46 PM gloops: unseasonably warm night
06:47 PM pink_vampire: here is 70
06:48 PM gloops: not sure what the temp is but im guessing around the same
06:51 PM pink_vampire: 21~C
06:55 PM * Tecan >>> Auto-op est suspendu...
07:05 PM Tom_L: CaptHindsight, for a friend
07:06 PM Tom_L: various robotics projects
07:12 PM pink_vampire: Tom_L: what kind of robot is that?
07:18 PM Tom_L: anything he decides to use them on
07:18 PM pink_vampire: oh ok
07:29 PM Tom_L: is there a hexchat for wheezy?
07:30 PM pink_vampire: what is hexchat?
07:31 PM Tom_L: irc client
07:32 PM CaptHindsight: yes if I recall correctly
07:33 PM CaptHindsight: https://packages.debian.org/wheezy-backports/hexchat
07:33 PM Tom_L: i had xchat on it but would rather have hexchat
07:33 PM Tom_L: at least i think it's wheezy
07:33 PM Tom_L: 10.04?
07:34 PM Tom_L: i forgot how to check
07:35 PM Tom_L: and i don't remember how to install backports :(
07:36 PM CaptHindsight: https://backports.debian.org/Instructions/
07:38 PM Tom_L: i don't think xchat was set up to use SASL
07:39 PM Tom_L: can't talk on the shop pc with chanserv in the channel
07:39 PM Tom_L: so i wanted to try and fix it
07:40 PM CaptHindsight: security is pretty messed up on a few distros
07:41 PM Tom_L: i've got hexchat working here and another windows box but i wanted to add it to wheezy
07:41 PM CaptHindsight: most distro maintainers are too busy or lazy to be bothered to do anything to fix things properly
07:51 PM Tom_L: ok i got it. thanks
07:53 PM pink_vampire: oily hands
07:53 PM pink_vampire: but 4 parts are done
07:54 PM CaptHindsight: not strain relief https://postimg.cc/7bqwTvvy
07:55 PM pink_vampire: CaptHindsight: this is common on those connectors
07:55 PM pink_vampire: you need to cut the ends shorter
07:56 PM pink_vampire: i need to clean the machine and make food
07:57 PM Tom_shop: ok, all is good in the world again
08:00 PM pink_vampire: what do you mean ?
08:02 PM Tom_L: i fixed my problem
08:04 PM pink_vampire: i'm cleaning
09:38 PM trentster: Just built a new cnc router machine that uses 2 steppers for Y axis, any opinions on the best way to use proxomity switches to home each side square?
09:40 PM trentster: I already have a working config from an existing machine, but I see there is a lot of ways to do it with dual. I am using 2 seperate drivers, 1 for each of the steppers.
09:40 PM hazzy: trentster: Are you using 2.7 or 2.8~pre? You really need to be using 2.8 to do it right ..
10:01 PM pink_vampire: trentster: just use the same signal to drive both motors
10:03 PM trentster: Hazzy, I am not sure the exact version, I havent touched my machine in about 2.5 years it must be 2.7.x something
10:09 PM pcw_home: Yeah, the right way is to use 2.8 and have 2 stepgens and 2 joints for Y (to allow proper gantry homing)
10:15 PM trentster: pcw_home: is 2.8 a must have for this?
10:16 PM trentster: I dont even see 2.8 on the main project page
10:16 PM trentster: isn't 2.7 current (stable)
10:16 PM CaptHindsight: trentster: it's the version that has support for 2 motors on one axis
10:17 PM pcw_home: If you want to do proper gantry homing 2.8 is better (with 2.7 there's a somewhat kludgy workaround (the gantry component)
10:18 PM pcw_home: 2.8 is the development version "master"
10:21 PM trentster: Damn…guess I will have to upgrade. I am loathe to touch it tbh, its been working flawlessly for 2.5 years without a hiccup.
10:21 PM trentster: Is recommended route to backup config and wipe and reload 2.8 from scratch using a bootable iso?
10:24 PM pcw_home: If its flawless I would leave it alone, If you need proper dual motor dual switch gantry homing 2.8 is your best bet
10:26 PM trentster: sigh…
10:26 PM trentster: Thanks guys (scratches head)
10:38 PM Kevin`: turn the current down, slam it into the end stops, and turn it back up. only sort of kidding :)
