12:15 AM Getty: Tom_L: Still awake?
12:18 AM XXCoder: tom dont tend to stay long
12:18 AM XXCoder: busy guy
12:18 AM Getty: ah ok
12:18 AM Getty: i was just kinda curious, cause he suggested me first that Ethernet Solution
12:18 AM Getty: isn't that like the master of latency?!
12:18 AM XXCoder: it uses that different from what I understand
12:18 AM XXCoder: thats why you dont use it with regular ethernet card
12:18 AM Getty: oh i see
01:31 AM ChunkyPuffs: Right, guys, I ned some help
01:32 AM ChunkyPuffs: this is getting dire
01:32 AM ChunkyPuffs: I can cut shit just fine, but I can't get the cut to go to the depths I want it to go to
01:32 AM ChunkyPuffs: this is a misunderstanding of fusion or something
02:29 AM Deejay: moin
02:58 AM crazyben: Good moning
02:58 AM crazyben: Good morning
02:59 AM XXCoder: good monetizing for you also
03:05 AM crazyben: Anyone here using ethercat on a 64-bit environment?
03:07 AM XXCoder: in what way? as network or as commucation cable between controller and machine?
03:07 AM crazyben: xxcoder: yes
03:07 AM XXCoder: on both? both isnt same thing.
03:08 AM crazyben: xxcoder: As a communication cable to control the machine.
03:09 AM XXCoder: there is MESA card that uses ethernet yeah
03:09 AM XXCoder: bits dont really matter in this respect.
03:14 AM crazyben: do you use this in your setup - if yes, on which os?
03:20 AM crazyben: can see my components now..
03:21 AM crazyben: ethercat slaves 0 0:0 PREOP + EK1100 EtherCAT-Koppler (2A E-Bus) 1 0:1 PREOP + EL1008 8K. Dig. Eingang 24V, 3ms 2 0:2 PREOP + EL2008 8K. Dig.

03:22 AM XXCoder: unofrtunately mine is BOB with TB6600s
03:22 AM XXCoder: parallel port interface
05:08 AM jthornton: morning
05:09 AM XXCoder: hey jt
05:14 AM XXCoder: how did making minium example go
05:15 AM jthornton: never did get it to work
05:15 AM XXCoder: yeah? one I modified from yours worked fine
05:16 AM XXCoder: or did you mean it didnt work with linucnc?
05:16 AM XXCoder: becaue I didnt test that
05:16 AM XXCoder: im pretty sure linuxcnc would require haltranslations defined
05:16 AM jthornton: I didn't try it on it's own just with linuxcnc
05:17 AM XXCoder: maybe just add a sphere at 0,0,0 and add haltranslation of all 3 axis on it
05:17 AM XXCoder: then move sphere upwards 400
05:17 AM XXCoder: then see if it works
05:35 AM jthornton: what did you modify to make it run stand alone?
05:36 AM XXCoder: all machines can be stand alone
05:37 AM XXCoder: just do this: phyton ./somefile assuming you in same dir
05:37 AM XXCoder: you wont be able to do anything besides change viewpoint zoom in out
05:37 AM XXCoder: but thats good for fast testing
05:37 AM jthornton: if you have the shebang line you just need to do ./nameoffile
05:37 AM XXCoder: chmod +x yeah
05:38 AM XXCoder: then can run it directly with simply ./whatever
05:38 AM XXCoder: if its not marked exec you would need to use python to run it
05:42 AM XXCoder: hm I wonder if +x is a requirement for linuxcnc to be able to run it
05:42 AM XXCoder: doubt it but lemme test
05:43 AM XXCoder: permission denied
05:43 AM jthornton: yea it is
05:45 AM XXCoder: loaded fine here now
05:49 AM XXCoder: what error is you getting?
05:51 AM jthornton: linuxcnc.error: emcStatusBuffer invalid err=3
06:04 AM XXCoder: cant figure that one
06:07 AM jthornton: I assume you should be able to just show one piece in the tk window?
06:08 AM XXCoder: yeah
06:08 AM XXCoder: tooltip and world have to be grouped into that object be besides that yeah
06:08 AM XXCoder: so minium 4, some object, tooltip work, and result of collection of all 3
06:11 AM Tom_L: morning
06:11 AM XXCoder: hey
06:11 AM XXCoder: haltranslate might be required lemme try
06:12 AM jthornton: ok
06:12 AM Tom_L: 44, Hi 39, Lo 22
06:12 AM Tom_L: cold is on the way again
06:15 AM jthornton: going to be pretty warm here today 62F
06:18 AM XXCoder: bleh! finally got it running
06:18 AM XXCoder: case of dumbass, apparently folder on desktop is a shortcut
06:18 AM XXCoder: so when I copied it to make test
06:19 AM XXCoder: well i was apparently modifing same folder no wonder it didnt work
06:19 AM XXCoder: so lemme test something
06:19 AM XXCoder: okay running fine
06:19 AM XXCoder: dont need any haltranslate
06:21 AM XXCoder: jthornton: http://dpaste.com/3CKD15Q
06:22 AM XXCoder: making something weird with it now. just dancing ball
06:24 AM jthornton: cool it finally works for me, prob don't need the pins yet I'll test
06:24 AM XXCoder: im checking if all 3 haltranslates can be assigned to single object lol
06:27 AM fragalot: hey
06:28 AM XXCoder: hey
06:29 AM jthornton: ok I finally got what I needed just the code to display the base and it's only a few lines
06:29 AM * fragalot needs to find an affordable ~40mm drill or long annular cutter to continue the part he's working on
06:29 AM fragalot: because screw going from 15mm up to 42mm with the boring head :P
06:29 AM XXCoder: yep very short
06:29 AM XXCoder: im still writing new ini almost done
06:31 AM XXCoder: some kind of error, no line drawing, or maybe sphere is too small. base is way too high so probably silly error
06:32 AM fragalot: shame forstner bits dont work on cast iron :p
06:32 AM jthornton: http://dpaste.com/2GQ4T58
06:32 AM XXCoder: super brief lol
06:32 AM jthornton: that's what I need for the docs super brief and to the point and most important it works!
06:33 AM XXCoder: btw using 3 haltranslates to single object apparently works. could see sphere move in all axis.
06:34 AM XXCoder: lol i tranplanted base not sphere no wonder places seemed swapped
06:35 AM jthornton: cool, paste that up when you get it done
06:35 AM jthornton: looks like firefox is forcing me to reboot lol
06:35 AM XXCoder: firefox is kinda broken all you need is close reopen firefox
06:36 AM XXCoder: sometimes have to wait few minutes
06:36 AM XXCoder: no reboot needed
06:36 AM jthornton: yea, I can't reboot right now anyway I have a terminal open running the coop automation
06:37 AM XXCoder: umm alpha dont work
06:37 AM XXCoder: ball should be 50% transparent
06:38 AM XXCoder: 10% I mean
06:40 AM XXCoder: http://dpaste.com/3EQ5BFB
06:40 AM XXCoder: enjoy lol
06:40 AM XXCoder: I changed ini to have 600x600x600 volume machine
06:40 AM XXCoder: base is much larger than actual work volume
06:40 AM jthornton: are you running that from linuxcnc?
06:41 AM XXCoder: apparently if you group work and tooptip in such way it shares same spot it wont draw a line
06:41 AM XXCoder: I moved work from sphere to base
06:41 AM XXCoder: yeah sphere just moving around and drawing a line. its a 3d etch
06:41 AM XXCoder: etch a sketch 3d version lol
06:46 AM jthornton: is the sphere the red dot?
06:48 AM XXCoder: yeah
06:48 AM XXCoder: its pretty tiny
06:48 AM XXCoder: i'd make it larger if transparencies work
06:48 AM XXCoder: it dont seem to be case
06:49 AM jthornton: ok, I just need to make the axis connections in hal now
06:57 AM weenerdog: good morning
06:59 AM XXCoder: hey hey
06:59 AM XXCoder: jthornton: bet it'd be fun to run a giant hilbert 3d grid with sphere vismach :P
07:02 AM weenerdog: thats something like i used to make fusion cry like a bitch. except it weaves over and under itself
07:02 AM weenerdog: but i got a plan. i was being stupid. i was making a height field instead of vector paths
07:07 AM jthornton: well I discovered more trickery and secret shit I hate to find if there is a file called sim_hardware.hal in the same directory it gets loaded even if it is not in the ini file...
07:08 AM jthornton: well maybe not dunno yet
07:08 AM XXCoder: hope not vismach is pretty conplex as is lol
07:08 AM XXCoder: I dont think can be more simpler and still axis than mine. well could have no base but hard to see movement otherwise lol
07:08 AM XXCoder: *still 3 axis
07:09 AM jthornton: lol I found out how it got loaded source sim_hardware.hal
07:09 AM jthornton: in the hal file...
07:10 AM XXCoder: it loads itself?
07:10 AM jthornton: should the red ball move when you run a file after connecting up the pins
07:10 AM jthornton: yea seems that way
07:10 AM jthornton: err no the main.hal file has that line
07:10 AM XXCoder: ahh
07:11 AM XXCoder: move as in move as commanded by linuxcnc? yeah
07:12 AM jthornton: I see the sphere.Xaxis and rest changing but the red ball does not move...
07:13 AM jthornton: http://dpaste.com/19HQS27
07:14 AM jthornton: http://dpaste.com/3HBG4RC
07:15 AM XXCoder: did you change test to sphere in hal and ini also?
07:15 AM XXCoder: ah you did
07:15 AM jthornton: ini?
07:15 AM XXCoder: yeah my mistake it has a name but its not critical
07:15 AM XXCoder: I think
07:16 AM XXCoder: MACHINE = sphere
07:17 AM XXCoder: line 13 or below version
07:17 AM XXCoder: dunno if its critical at all
07:17 AM jthornton: that should just be the name in axis
07:17 AM XXCoder: yeah
07:17 AM XXCoder: hmm strange that sphere dont move.
07:17 AM XXCoder: wonder if 2.8 changed so single object cant have 3 haltranslates?
07:34 AM XXCoder: jthornton: learned something new
07:35 AM XXCoder: tooltip must be group with lowest base object. it cant be collection with a collection and work
07:35 AM XXCoder: for example if I define sphere and cylinder, collection them together, then collection them again with tooltip it wont draw
07:36 AM XXCoder: would need to collection tooltip with say cylinder, then collection them with sphere
07:40 AM jthornton: can you paste that example?
07:41 AM XXCoder: nah it was abstract
07:41 AM XXCoder: i was curious if I could do 3 sphere, one only x, one xy motion and one xyz motion then attach tooltip to last one
07:41 AM XXCoder: drawing refused to work
07:42 AM XXCoder: I reverted it to single sphere like one you saw
07:44 AM jthornton: does the single sphere move for you?
07:44 AM XXCoder: yeah
07:44 AM XXCoder: in all 3 axis
07:44 AM jthornton: your using 2.7?
07:44 AM XXCoder: running it and manual moves dont work?
07:44 AM XXCoder: yeah
09:31 AM gloops: https://www.ebay.co.uk/itm/ENGINEERS-3-MORSE-TAPER-SHANK-DRILLS-IMPERIAL-QTY-8/392175102280? start collecting stuff like this fragalot
09:33 AM Getty: https://twitter.com/mr_peterdowning/status/1066393475367747584 you guys might lke this :D
09:36 AM fragalot: gloops: thanks :-) -- I'll need to figure out whether or not I can hold these in the schaublin though
09:37 AM fragalot: i've got morse adapters for it, but they require threads to pull it up into the spindle.. so doesn't work with those tails
09:37 AM jthornton: tapers on a couple look pretty beat up...
09:41 AM fragalot: jthornton: and the grinds look AWFUL too :P
09:41 AM jthornton: it did say assume they needed a regrind lol
09:41 AM fragalot: but if it stays below £50 or so I don't mind a few of them being unusable
09:41 AM fragalot: also, has anyone else ever noticed how ebay will sometimes NOT show you ANY items in one of their shops?
09:41 AM fragalot: that kevstools' store for example shows as cmpletely empty for me right now
09:47 AM JT-Shop: me too
09:48 AM Tom_L: playin with a bouncin ball today ehh?
09:48 AM Tom_L: snow started a bit ago
09:52 AM fragalot: JT-Shop: do you have any experience with indexable drills?
09:52 AM fragalot: i'm wondering if they require more or less power than conventional drills, given their tendency to have less of a taper on the tip
09:53 AM Tom_L: we used some 3" ones on some Ti parts
09:53 AM tiwake: fragalot: less pushing more RPM
09:53 AM Tom_L: power wise i'm not sure
09:53 AM Tom_L: not in Ti :D
09:53 AM fragalot: tiwake: more curious whether the schaublin's 3kW spindle can push them or not
09:53 AM tiwake: well sure
09:54 AM fragalot: around 40mm dia
09:54 AM tiwake: fragalot: donno... I don't do metric
09:54 AM tiwake: :P
09:54 AM fragalot: about 1.6"
09:54 AM tiwake: insert drill or insert spade drill or something else?
09:54 AM tiwake: I've done lots with both
09:55 AM fragalot: either, open to suggestions
09:55 AM tiwake: what material?
09:55 AM tiwake: and volume
09:55 AM tiwake: heh
09:55 AM fragalot: cast iron
09:55 AM tiwake: oh pff whatever works
09:55 AM fragalot: pre-drilled at 15mm, 60mm deep
09:55 AM tiwake: use insert drill
09:55 AM * fragalot => ebay
09:55 AM tiwake: spade drills don't like pilot holes
09:56 AM JT-Shop: fragalot: I think I have one somewhere lol, I guess the load depends on the insert
09:56 AM Tom_L: make sure you can get the inserts for them
09:56 AM fragalot: Tom_L: yea :P
09:56 AM tiwake: the problem with insert drills is you can't really change the size of the hole, so make sure you get exactly the size you need
09:56 AM fragalot: had fun yesterday roughing out the horizontal support bracket for the mill
09:57 AM fragalot: especially once you realize "hang on this thing has a horizontal spindle"
09:57 AM tiwake: spade drills give you a large-ish range of insert spade options
09:57 AM JT-Shop: Tom_L: just trying to understand vismach so I can make sense out of the documents
09:57 AM tiwake: but they hate pilot holes
09:57 AM fragalot: tiwake: I plan on boring to size, I just want to reduce the roughing time
09:57 AM tiwake: cast iron? its going to be butter
09:57 AM tiwake: so spin it up
09:57 AM fragalot: lathe isn't big enough
09:58 AM tiwake: fragalot: what is the volume?
09:59 AM fragalot: 5,5x5,5x2,5 "
09:59 AM tiwake: no, I mean volume of parts per week or month or whatever
09:59 AM fragalot: https://www.youtube.com/watch?v=Cw7Mwd6ey6g <== that thing
09:59 AM fragalot: tiwake: one.
10:00 AM tiwake: just doing one? merf... just use a roughing endmill then
10:00 AM tiwake: and G13 it up
10:00 AM fragalot: manual machine
10:00 AM fragalot: but.. I can peck it out
10:01 AM fragalot: thanks for the suggestion
10:01 AM tiwake: there is no reason to use a $200 tool for making a 1.6" hole for one part
10:01 AM tiwake: lol
10:01 AM tiwake: unless you want to use it for other things
10:01 AM fragalot: they can be found used for far less, and don't wear out in the home shop.. ever :P
10:03 AM tiwake: do whatever you want... I'm just suggesting crap based on.. well... my experience with such tools
10:03 AM fragalot: but I didn't want to risk spending ~ €60 on one (plus inserts) if a 3kW spindle wouldn't run it
10:03 AM fragalot: hence asking about that in the beginning
10:03 AM tiwake: thats like 1.something hp?
10:04 AM fragalot: 4hp
10:04 AM tiwake: its cast iron, it will be fine
10:04 AM fragalot: sweet
10:04 AM tiwake: steel? more issues, but not horrible
10:06 AM fragalot: I figured out the ebay issu
10:07 AM fragalot: change the "post to ...." on the right, and suddenly it all shows.
10:07 AM Tom_L: JT-Shop, have you seen this one: https://www.youtube.com/watch?v=JbPgHUxsEBA
10:09 AM Tom_L: https://www.youtube.com/watch?v=1JzuyvvDWzc
10:09 AM Tom_L: even better
10:10 AM JT-Shop2: saw the former but not the latter, both quite impressive but no clue how they did it lol
10:10 AM Tom_L: doesn't appear vismach can show material removal like commercial products
10:10 AM fragalot: that's cool
10:12 AM Tom_L: shows possibilities though
10:18 AM JT-Shop2: last day of vacation for me gotta get something done...
10:18 AM Tom_L: expecting cold in a day or so?
10:20 AM JT-Shop: tomorrow night the cold will arrive here
10:20 AM Tom_L: not alot of snow but it's sure windy
10:22 AM JT-Shop: we are supposed to get up to 40 mph gusts tonight
10:23 AM Tom_L: Wind Speed: 38mph
11:43 AM ChunkyPuffs: Hey guys do you think I can do 6mm at a time with a 12mm 2 flute flat?
11:43 AM ChunkyPuffs: on wood
11:43 AM ChunkyPuffs: carbide
11:43 AM fragalot: depends on the wood & how rigid your router is, but.. absolutely.
11:53 AM gloops: id use a spiral cutter, depends on the wood, and your machine, like oak is a lot harder than pine
11:54 AM fragalot: i've found oak cuts a lot nicer
11:55 AM fragalot: (assuming sharp tool)
11:58 AM gloops: oak does cut well yeah, ive found pine to be more variable, some cuts great, another piece doesnt
11:58 AM fragalot: yeah.. some days you get a piece with tight grain that works well, other times you get stuff with like 10mm growth rings
11:59 AM gloops: there is only one way to really know the outcome of a given speed and cut etc heh
12:03 PM ChunkyPuffs: streaming on https://twitch.tv/memetic_ again
12:03 PM ChunkyPuffs: so you can see the outcome of this horrendous experiment
12:03 PM ChunkyPuffs: hope I don't break the bit
12:05 PM ChunkyPuffs: just going to do it at 4mm per passes instead, to avoid potential horrendous behaviour
12:05 PM fragalot: Good luck :-)
12:06 PM gloops: i can show you a vid that proves the outcome...
12:06 PM gloops: but you try first ;)
12:07 PM fragalot: yea gloops but you were plunging with a cutter that wasn't designed to plunge :P
12:07 PM John_ is now known as Guest27703
12:07 PM gloops: not that one lol
12:07 PM fragalot: :D
12:10 PM gloops: 21mm pass https://www.youtube.com/watch?v=XL18xJf0_Do&t=1s
12:11 PM gloops: a flat bit needs slower feed
12:13 PM Rab: gloops, what's the rated power of that spindle?
12:14 PM gloops: 800w
12:15 PM gloops: the dovetails are actually perfect, if i say so myself, no breakout or chipping
12:27 PM ChunkyPuffs: gloops, generally speaking, what needs to change as you get larger flat heads?
12:27 PM ChunkyPuffs: do you need to reduce the rpm? do you need to reduce the feedrate?
12:29 PM fragalot: ChunkyPuffs: typically you want to keep the chip per tooth the same, and the rpm optimal for the material & cutter combination you have
12:30 PM ChunkyPuffs: so feedrate stays the same fragalot ?
12:30 PM MarcelineVQ: which would be a good idea to use a calculator to determine
12:30 PM ChunkyPuffs: I'm not really advanced enough yet to know what chip per tooth is
12:30 PM fragalot: ChunkyPuffs: it should be one of the fields in fusion
12:30 PM ChunkyPuffs: My cnc doesn't have control over it
12:30 PM fragalot: chip per tooth == how much each tooth cuts away each time it spins around
12:30 PM fragalot: so if you lower the RPM, your feedrate goes down
12:30 PM ChunkyPuffs: you set the feedrate and speed, that's all I can adjust in my software
12:30 PM fragalot: if you increase RPM your feedrate goes up
12:31 PM fragalot: if you increase in diameter, your surface speed goes up, so you reduce the RPM to compensate
12:31 PM ChunkyPuffs: which in effect means lowering feedrate/
12:31 PM ChunkyPuffs: but you have to manually lower your feedrate ,right?
12:31 PM fragalot: if you don't have a CAM software to figure that out for you, yes.
12:32 PM MarcelineVQ: ChunkyPuffs, search "speeds and feeds" on youtube
12:32 PM fragalot: for wood, the range that you can work in is quite forgiving though
12:35 PM ChunkyPuffs: MarcelineVQ, I'm aware of the concept
12:35 PM ChunkyPuffs: so now I'm asking what exactly it is that I have to do for larger bits
12:35 PM ChunkyPuffs: speeds and feeds relates to material more than it does to the cutter
12:36 PM ChunkyPuffs: so a search result is about that more than what I want, which is info about the cutters
12:36 PM fragalot: carbide can take much higher feedrates, as it is more rigid, and can stand the heat better
12:36 PM gloops: the straight bits cant clear chips like a spiral cutter, you need to drop the feed/speed
12:36 PM fragalot: or an air blast
12:36 PM ChunkyPuffs: so would you say 20k RPM 1500mm/min is too much for a 2 flute flat head?
12:37 PM gloops: for a deep cut probably yes
12:37 PM ChunkyPuffs: 6mm per cut
12:37 PM fragalot: hit go & listen.. if it sounds wrong, it probably is
12:37 PM ChunkyPuffs: I'm not riskin a £20 bit on that
12:37 PM gloops: depending on the cutter youre looking at a mm or 2 per pass, for deep cuts slow it right down
12:37 PM ChunkyPuffs: yet
12:38 PM fragalot: ChunkyPuffs: so start slow
12:38 PM ChunkyPuffs: there's no such thing lol
12:38 PM ChunkyPuffs: you don't have time to react
12:38 PM gloops: 12ipm is not uncommon for pine you know
12:38 PM ChunkyPuffs: the cut either works or it doesn't, you either take it too far or you don't
12:39 PM gloops: try 750mm/min maybe 300mm for plunging
12:40 PM gloops: it wants to be cutting its way through, not smashing
12:45 PM John_ is now known as Guest70957
01:07 PM Tom_L: ChunkyPuffs you gettin a handle on feeds n speeds yet?
01:07 PM Tom_L: chipload is the amount of material removed by a tooth in one revolution
01:08 PM Tom_L: https://www.youtube.com/watch?v=AQlgvApxQBo
01:31 PM gloops: got it cutting yet ChunkyPuffs
01:32 PM ChunkyPuffs: not quite gloops
01:32 PM ChunkyPuffs: I'm gonna try metal with a 3mm 1 flute
01:32 PM fragalot: before doing the wood thing?
01:32 PM ChunkyPuffs: I'm a bit tired though, been up 48hrs
01:32 PM ChunkyPuffs: yeah before doing the wood thing, I've had a few successful wood cuts before
01:33 PM ChunkyPuffs: I don't have access to a 6mm bit, or optimal stock for the wood though, so it's limiting, i have 4mm aluminum here
01:33 PM gloops: 3mm snaps very easily with metal lol
01:34 PM fragalot: alu is tricky
01:34 PM fragalot: do NOT let ANY heat build up around the bit
01:34 PM MarcelineVQ: it is, going to slow welds the chip to your bit
01:34 PM MarcelineVQ: and it gets worse from there
01:35 PM gloops: the perennial issue with routers and aluminium is spindle speed, they nearly all have high speed spindles which have little torque at low revs and risk overheating
01:35 PM fragalot: gloops: at the same time, a 3mm bit single flute calls for high RPM
01:35 PM fragalot: but, you are correct.
01:37 PM MarcelineVQ: on the plus side, it should be quite easy to find speed and feed charts for aluminum
01:41 PM Tom_L: single flute on metal probably not the best idea
01:42 PM fragalot: Tom_L: works fine on alu
01:42 PM fragalot: ask datron if you have any doubts :P
01:42 PM Tom_L: meh, i believe you
01:42 PM Tom_L: i'd just rather have 2
01:42 PM MarcelineVQ: 1 and 2 flute are ideal for alu, afaik
01:42 PM Tom_L: some like 3
01:43 PM fragalot: Tom_L: 2 is fine, IF your machine can move fast enough to keep the chipload nominal
01:43 PM Tom_L: yeah
01:43 PM fragalot: and that is where a single flute comes in
01:46 PM jbar: Is your machine primarily a router for wood or a milling machine for metal?
01:47 PM ChunkyPuffs: gonna do it tomorrow
01:55 PM gloops: single flute allows lower feed at fast spindle revs - useful for steady stepper machines
01:57 PM gloops: and a lot of these feed/speed calculators are assuming a solid milling machine, not a router built with tinny extrusions lol
02:10 PM gloops: Ukraine says that a second boat has been hit by Russian fire, and two crew members were wounded.
02:10 PM gloops: looks like it might be kicking off over there
02:28 PM gregcnc: all feed speed calculators assume best case conditions with coolant and good chip clearing
02:33 PM Tom_L: sharp tools & rigid machine
02:34 PM Tom_L: took me a couple trys to find the happy spot on my little mill
02:34 PM Tom_L: stay there and it works great
02:40 PM tiwake: anyone happen to know of a good SIP phone service subscription?
02:43 PM gloops: optimum speed/feed doesnt apply when your main concern is cutting down the vibrations
02:44 PM gregcnc: optimum?
02:45 PM Roguish: tiwake: https://www.ooma.com/
02:46 PM Roguish: been using 'em for years. good enough. bill is appox $4 per month
02:46 PM tiwake: Roguish: can I install my own SIP client on my computers?
02:47 PM XXCoder: Tom_L: yeah impressive as heck, that machine
02:47 PM Roguish: not sure about that. don't think so, need one of their boxes, i believe. about $70 now. check 'em out at least.
02:48 PM XXCoder: but yeah while vismach requires work object to be made and included, it doesnt do anything
02:48 PM tiwake: Roguish: because I'd like to have the service for the same phone number on my cellphone, and my cellphone does not run on iOS or android
02:48 PM XXCoder: you could add stock shape yourself but besides it being there there is no effect
02:48 PM Roguish: tiwake: that's beyond me. good luck. let us know how it works out.
02:49 PM XXCoder: I wonder if there was supposed to be input on stock size and it feeds to vismach so it could show it. even if it doesnt show cuts with good transparancy (which doesnt work) it would be quite effective
02:49 PM tiwake: Roguish: if its a regular SIP phone service, I can get whatever SIP client I want, cisco phones, whatever SIP client I want on windows or linux or whatever
02:49 PM XXCoder: s/cuts/cuts,
02:51 PM Tom_L: none of the examples i've seen show stock
02:51 PM Tom_L: except maybe one lathe example
02:52 PM XXCoder: youtube there is one actually but none included in linuxcnc
02:52 PM XXCoder: toolchange one. it keeps smashing into stock with tool changes lol
02:52 PM XXCoder: going off later :)
02:58 PM tiwake: Roguish: yeah, its not going to be flexible enough to do what I want
03:16 PM Deejay: gn8
05:19 PM andypugh: Quick project: https://www.thingiverse.com/thing:3238845
06:07 PM Tom_L: good idea andy
06:09 PM Tom_L: do magnets affect those calipers at all?
06:09 PM Tom_L: they're capacitive aren't they?
06:20 PM andypugh: Doesn’t seem to have any effect
07:35 PM XXCoder: Tom_L: I think it uses rolls to measure motion but could be wrong
07:39 PM Net|: https://www.ebay.ca/itm/Seagate-Expansion-8TB-Desktop-External-Hard-Drive-USB-3-0-STEB8000100/282703004987
07:40 PM XXCoder: selling yours eh
07:54 PM MarcelineVQ: XXCoder: rolls?
07:54 PM XXCoder: roller whatever its called
07:55 PM XXCoder: its wheel on the part that slides out
07:55 PM XXCoder: but not certain if thats the case since if it is, it could easilt slip or something
07:55 PM MarcelineVQ: ah, no that's just a wheel for precision sliding
07:55 PM XXCoder: not that one
07:55 PM XXCoder: internal
07:56 PM MarcelineVQ: nah there's no mechanical parts inside, https://www.wonkeedonkeetools.co.uk/calipers/how-does-a-digital-caliper-work/
07:56 PM Tom_L: As the sliding jaw travels along the main scale, the rectangular plates align and misalign and the capacitance (the amount of electrical charge) between the plates changes. This sends a signal to a chip within the caliper, which generates the readings shown on the LCD display.
07:56 PM XXCoder: nice site reading
07:57 PM Tom_L: hah i got mine from google
07:58 PM XXCoder: capatence nice
08:23 PM milkii_ is now known as milkii
09:31 PM Getty: So I think its stepper
09:31 PM Getty: cause it says STEPPER MOTOR 8-D
09:32 PM Getty: aehm STEPPING MOTOR so :D
09:32 PM Getty: i am no expert, tho :D
09:32 PM Getty: the bad part is, that i now noticed that a) i cant see the motor of the 2nd axis and b) there is only the Parallel Port as any output of the device at all
09:32 PM Getty: i feel trouble coming up
09:33 PM XXCoder: nice
09:33 PM Getty: nice?
09:33 PM XXCoder: finding out that its stepper
09:33 PM XXCoder: little bit of latency here
09:33 PM XXCoder: have you looked if there is electrics box anywhere in it, like under table
09:34 PM XXCoder: if not that dos box probably is directly controlling it
09:34 PM XXCoder: but then where do steppers get power as parallel port cant supply that much amps
09:34 PM XXCoder: sounds like wiring tracing in your future
09:35 PM Getty: they got a power of course
09:35 PM Getty: i mean thre is one power connector
09:35 PM Getty: wait a sec must find out how to make an album again on imgur
09:35 PM XXCoder: does it just go to psu?
09:36 PM Getty: https://imgur.com/a/SQEtATF
09:36 PM Getty: here the album of the corner stones
09:36 PM Getty: that one motor i can see, the parallel port connector with nothing else around, the drill and the power connector
09:36 PM XXCoder: IO bet you electrics is under inside box]
09:36 PM XXCoder: you might have to lift and remove cover
09:37 PM Getty: well inside then, there is just plate under it
09:37 PM Getty: question
09:37 PM XXCoder: or top
09:37 PM Getty: do we really want that?
09:37 PM XXCoder: pictured your router table seem to have alum board with bolts on it?
09:37 PM Getty: yes
09:37 PM XXCoder: if so, just draw its orginial position on it and remove
09:38 PM XXCoder: and hope orginial designer was smart enough to design in maintanability
09:38 PM Getty: what you mean? https://i.imgur.com/UC4o29c.jpg here the picture again
09:39 PM Getty: i feel like that box wasnt made to be opened
09:39 PM XXCoder: the BIG sheet of alim resting on extrude frame on bottom
09:39 PM XXCoder: alum
09:39 PM XXCoder: look around it see if anything is bolted on it
09:40 PM Getty: you mean under it?
09:40 PM Getty: let me see
09:40 PM XXCoder: lets picture it as collection of connected boxes, cover I am talking about is top of lowest box
09:40 PM XXCoder: also biggest
09:41 PM XXCoder: hopefully you will be able to just unbolt and remove cover
09:42 PM Getty: "unbolt"
09:42 PM Getty: how you unbolt at all?! :D
09:42 PM XXCoder: lemme download pic and paint on it a second
09:44 PM XXCoder: https://imgur.com/a/FaIjZ2t
09:44 PM Getty: ok rearranged pictures and added 2 new ones: https://imgur.com/a/SQEtATF
09:45 PM Getty: cause there is another connector i just realized not sure what it should be
09:45 PM Getty: and the bottom is pretty much solid bolted
09:45 PM XXCoder: yeah looks like it
09:45 PM Getty: XXCoder: yeah those are bolts, how you remove them?
09:45 PM XXCoder: its likely bolts to hold on drivers and such
09:45 PM XXCoder: bottom one
09:45 PM XXCoder: top looks like hex tools
09:45 PM Getty: cant we do something with the parallel printer?
09:46 PM Getty: i mean we do have the DOS stuff still :D
09:46 PM XXCoder: you'd have to look around and see if top has stuff on top of it
09:46 PM Getty: what you mean?
09:46 PM XXCoder: if not then cover should be easy enough to remove
09:46 PM XXCoder: anything on top being bolted to cover
09:46 PM Getty: i am confused i have no idea how many bolts are under the stuff
09:47 PM Getty: next to the fact that i do not know how to remove the construction on top
09:47 PM Getty: it seems pretty much like a blackbox-click-here-shit
09:47 PM XXCoder: what I mean is stuff on top connected to only sides or is there anywhere in middle also?
09:48 PM Getty: i am confused, sorry, english not native language, so i am getting confuse what you mean
09:48 PM XXCoder: can ypu take a picture, directly into front or back of machine in such way that gantry sides is to left and right?
09:48 PM Getty: you see in the pictures everything i can see more or less
09:48 PM Getty: i am unsure.... what you mean exactly for a direction here
09:49 PM Getty: you mean like into the flow?
09:49 PM Getty: like "being the plate"? :D
09:49 PM Getty: i doubt you see much, i mean i know there is not anything really beside the slides for the holder
09:49 PM XXCoder: your picture is downwards into top of machine
09:50 PM XXCoder: what I want is just picture of sides of machine
09:50 PM Getty: you see all the connectors that are on the sides
09:50 PM Getty: else the box is solid metal
09:50 PM Getty: in the pictures
09:50 PM Getty: 3 connectors, one for power, one for parallel port, one... other thing
09:50 PM Getty: oh you mean like if there are screws or something to remove it from there
09:51 PM Getty: ?
09:51 PM XXCoder: im not sure how to properly access the elctrics in box
09:51 PM Getty: i feel like my dad has never ever opened that thing
09:51 PM Getty: what can we do through the parallel port?
09:51 PM Getty: i mean is there probably a way to find out what machine and have some "driver" for it on LinuxCNC?
09:52 PM XXCoder: hard to say, maybe can reverse engineer pins and find what pin needs what data
09:52 PM XXCoder: if its even compitable with more modern cnc protocols
09:52 PM Getty: well we still have the DOS machine and can get more detailed information about what we have
09:52 PM Getty: independent of the not much that is standing on the machine
09:52 PM XXCoder: you can boot dos machine and get configuration info?
09:52 PM Getty: i hope! didnt tried yet
09:53 PM Getty: i could probably remove the harddisc best
09:53 PM XXCoder: hopefully it does have info
09:53 PM Getty: and just attach it via some bay and access it via linux
09:53 PM XXCoder: if its old enough it might use some weird filesystem but yeah
09:53 PM Getty: its a DOS
09:53 PM Getty: so i know what filesystem ;)
09:53 PM Getty: FATFS
09:53 PM Getty: ;)
09:53 PM XXCoder: fat16 likely yeah
09:54 PM Getty: it actually doesnt matter which fat
09:54 PM Getty: all the fats are totally compatible
09:54 PM XXCoder: yay we all like fat ;)
09:54 PM XXCoder: do you have PATA connector on your pc?
09:54 PM XXCoder: sata nowdays
09:54 PM Getty: i dont have yet any PC at the room
09:55 PM Getty: i doubt the harddisc is sata ;) its proably IDE
09:55 PM XXCoder: yeah ide uses PATA
09:55 PM Getty: but i got some IDE2USB thing somewhere or i buy one
09:55 PM XXCoder: not bad
09:55 PM Getty: but that also simplifies the computer situation a bit
09:55 PM Getty: that i just need a parallel port at first before i buy any actual I/O card
09:55 PM XXCoder: yeah hopefully it has list of pins and what data it expects
09:56 PM XXCoder: and hopefully its a controller linuxcnc can run
09:56 PM XXCoder: if not you would need to replace drivers and stuff in machine
09:57 PM XXCoder: maybe MESA ethernet or something, as well as whatever stepper drivers that can run yours
09:57 PM XXCoder: your steppers has voltage and amp required?
09:57 PM Getty: i hope i dont need to open that box cause i will never be able to close it again
09:57 PM Getty: https://i.imgur.com/S7g1em4.jpg?2
09:58 PM XXCoder: 4v 1a wow pretty small
09:58 PM XXCoder: 1.8 degree per step thats very typical
09:58 PM Getty: https://i.imgur.com/lhV1C2Q.jpg?2
09:58 PM Getty: and thats the drill
09:58 PM Getty: i got a complete set of drills actually
09:58 PM Getty: got at least 3 other PROXXON packages
09:58 PM XXCoder: drill is powered on and off manually or machine does it?
09:59 PM Getty: there is a switch at it, probably manually
09:59 PM XXCoder: im looking up tb6600 stats
10:00 PM XXCoder: 5v, 0.5a to 3.5a
10:02 PM XXCoder: anyway first thing is make a disk image of your old dos systenm
10:02 PM XXCoder: need backup in case it decides to die
10:02 PM XXCoder: it may well have docs as well as program to run it
10:03 PM Getty: yeah sure, it is a common software he used with some configuration file for the setup
10:03 PM Getty: some very old DOS stuff
10:04 PM XXCoder: indeed. that configure file is what you want
10:04 PM Getty: so i am very certain we will get results
10:04 PM XXCoder: hopefully its readable, or program can read and have gui for displaying said settings.
10:04 PM Getty: else we just hammer the parallel and see what happens :D
10:05 PM XXCoder: lol risky
10:05 PM XXCoder: could send axis signal to one pin a time
10:05 PM XXCoder: but I dont know how risky it ius
10:06 PM XXCoder: expecially since you need axis enable pin also if it has such thing also
10:06 PM Getty: if i remove the drill there cant be actually much happening
10:07 PM XXCoder: yeah just be careful and make sure all axis is in middle of position range
10:08 PM XXCoder: so you can jog it small distance see if it works
10:08 PM XXCoder: but honestly reverse engineering first likely make job so much easier.
10:08 PM Getty: well all steps at a time! :D
10:08 PM Getty: i also need for sure get a computer for there... still tiggling if i should get that T30! :D
10:10 PM Getty: i assume i shouldn't use parallelport via USB, or?
10:10 PM XXCoder: usb cant do realtime
10:11 PM XXCoder: cpu being too busy can "freeze" usb when you hit e-stop and want machine to stop now
11:19 PM Getty: this t30 is actually not that bad for the job, i thought about finding another non-server PC and the problem is that most of them lag the PCIe
11:21 PM XXCoder: my pc isnt a server and works fine
11:41 PM Getty: my job is to write software, i have a hard time producing cost
11:41 PM Getty: so i take any chance! :D
11:41 PM XXCoder: programmer eh
11:42 PM Getty: well, a real full stack one, cable to cloud
11:42 PM XXCoder: nice
11:43 PM XXCoder: i learned at college and got CS degree but couldnt find a job
11:43 PM XXCoder: so im machinist now
11:44 PM Getty: i never learned anywhere, and just once had no job.. for 2 months.. before i made my own company ;)
11:44 PM XXCoder: thats even better
11:44 PM Getty: but that company is dead.... and converted into a real one, like from Freelance to LLC in US terms
11:46 PM XXCoder: not bad
11:46 PM XXCoder: growing business?
11:46 PM Getty: well not really, still fighting with legacy and parallel earning money "by the hours"
11:47 PM Getty: but i already invested a lot for pursueing the real company target: game development
11:47 PM Getty: i got literally a complete arcade here, including motion chair
11:49 PM XXCoder: this is what I want to have
11:49 PM XXCoder: whole arcade booth with asteroids
11:49 PM XXCoder: though with extra buttons to switch to other vector games
11:49 PM Getty: you are sitting in US?
11:50 PM XXCoder: yeah im in usa
11:50 PM Getty: my condulences
11:50 PM XXCoder: lol
11:52 PM Getty: XXCoder: but if you wanna become a game developer, i can push you into the right directions, i can always take extensions to my team! :D
11:53 PM XXCoder: its been too long, I have forgotten much of programming though I can do it somewhat
11:53 PM XXCoder: I recently reverse engineered vismach examples and made my own version
11:53 PM XXCoder: it'll be included in latest copies of linuxcnc 2.7 and 2.8
11:53 PM Getty: a moron can become a game developer
11:54 PM Getty: you dont even need to program, one of my friends denies to make code even tho he is a programmer, but he wanna solve everything without code, which is these days possible
11:54 PM Getty: (nearly)
11:56 PM XXCoder: right now i'm ok with being a machinist just unsure what to do in future
11:59 PM Getty: thats why i went to make that gaming company
11:59 PM Getty: i wanna make games, that is the best future i can imagine that still can bring in cash
11:59 PM Getty: beside caring for puppies
