12:16 AM CaptHindsight: Open-Source Selective Laser Sintering (OpenSLS) of Nylon and Biocompatible Polycaprolactone
12:19 AM CaptHindsight: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4739701/
12:19 AM CaptHindsight: he used a 40W laser from Automation technologies (chinaco)
12:19 AM CaptHindsight: and a *duino
12:19 AM r0n0x: ooh
12:26 AM fragalot: hi
12:32 AM CaptHindsight: fragalot: any idea what SLS powders are selling for there? money/kg
12:32 AM fragalot: no, sorry
12:32 AM fragalot: we don't own any SLS
12:32 AM CaptHindsight: no problem just wondering
12:34 AM fragalot: doc: I'm sorry but I have bad news, and worse news.
12:34 AM fragalot: The bad news, is that you have 24 hours left to live
12:34 AM fragalot: guy: what is the worse news???
12:34 AM fragalot: doc: I meant to tell you yesterday
12:36 AM CaptHindsight: https://www.youtube.com/watch?v=g-4-gLlF0uw
12:37 AM fragalot: thank you.
12:49 AM r0n0x: what about metal SLS?
12:49 AM fragalot: that's SLM. :P
12:49 AM * r0n0x looks at a bag of aluminium powder
12:50 AM r0n0x: how strong a laser you need for that though? seems like something fun to try out
12:51 AM fragalot: for a small build? maybe 400W fiber as a minimum?
12:54 AM r0n0x: :(
12:55 AM r0n0x: how hard to do plastic then?
12:55 AM r0n0x: to make the printer
12:55 AM fragalot: don't need that much power for those if you aren't concerned about speed
12:56 AM fragalot: there should be plenty of examples out there
12:58 AM fragalot: mornin'
12:59 AM miss0r: mornin..
12:59 AM miss0r: I've been up 5 times last night.. The kid just wont sleep properly for the time being
12:59 AM fragalot: :/
01:00 AM r0n0x: oh neat
01:01 AM miss0r: With every sip of coffee I am slowly transforming from a tired looking neanderthal to a slightly less tiredlooking one
01:01 AM r0n0x: so how hard is it to make the printer, lasering aside
01:01 AM fragalot: r0n0x: how mechanically inclined are you?
01:01 AM fragalot: just like everything, it's all about getting the right lego pieces in the right place, and nothing more
01:01 AM fragalot: how difficult that is, depends on you. :)
01:07 AM r0n0x: i dont understand what you mean
01:07 AM fragalot: how good are you at screwing things together properly
01:07 AM miss0r: heh
01:07 AM r0n0x: good
01:07 AM fragalot: in that case, it's not that hard
01:07 AM r0n0x: what does the powder wiping thing need?
01:07 AM fragalot: gloops: https://imgur.com/gallery/OkJJz
01:08 AM r0n0x: vs say, an i3
01:08 AM r0n0x: hmm
01:08 AM fragalot: downside is that they are harder to build, powders cost more, and the prints are very messy to get out of the box of powder when done
01:09 AM Wolf__: printing with laser sounds cooler
01:09 AM r0n0x: from the looks of it, the finish is shit
01:10 AM fragalot: that depends on the printer & the person using it
01:10 AM r0n0x: so i cant quite tell how strong it is
01:10 AM r0n0x: or what the layer bonding is like
01:10 AM r0n0x: or is it effectively solid?
01:10 AM Wolf__: SLS cant be that good, SpaceX uses it to make rocket engine parts...
01:10 AM fragalot: the finish should be similar to about 320grit sandpaper
01:10 AM fragalot: Wolf__: SLS or SLM?
01:10 AM fragalot: r0n0x: solid
01:11 AM Wolf__: probably SLM, they print in inconel
01:11 AM r0n0x: so, effectively identical to say, molded plastic
01:11 AM r0n0x: i might try making a small one
01:11 AM fragalot: r0n0x: for all intents & purposes, yes
01:11 AM miss0r: I just want a DLP 3D printer
01:12 AM r0n0x: dlp?
01:12 AM fragalot: miss0r: shame though that the parts themselves aren't stable over time when exposed to UV
01:12 AM miss0r: google DLP 3D printer
01:12 AM Wolf__: I have no idea which is what, how many ways are there to melt metal powder together
01:12 AM r0n0x: O:
01:12 AM miss0r: fragalot: yeah, you need to paint them / keep them out of sunlight.
01:12 AM r0n0x: brain idea
01:12 AM fragalot: Wolf__: SLM, EBM, and sintering & infusing.
01:12 AM miss0r: The quality is THA BOMB !
01:13 AM fragalot: Wolf__: oh, and stacking & tacking sheets :P
01:13 AM r0n0x: combine powder printer with copper foil to create printed PCB
01:13 AM Wolf__: SLM = sintering?
01:13 AM r0n0x: XD
01:13 AM fragalot: Wolf__: and also powder guns or mig welders on a robot arm :P
01:13 AM r0n0x: seriously speaking though i think SLS might be my solution to producing larger scale centrifugal fan blades
01:14 AM fragalot: Wolf__: the sintering i'm talking about is a very coarse bronze "green" print, which you infuse with a different metal later to bond it properly
01:14 AM r0n0x: extrusion printed ones tend to split at the layer bond and then explode
01:14 AM fragalot: r0n0x: yeah they'd work a lot better
01:14 AM Wolf__: ah ok, they are using direct on inconel powder
01:14 AM fragalot: Wolf__: oh and there is also sand printing to print the mold & cast your part later
01:14 AM fragalot: so, there are quite a few metal printing methods
01:15 AM r0n0x: the issue is the internal stress from printing that way, large thin flat
01:15 AM fragalot: the main issue that we still have at work is that you essentially need one machine per material you wish to use if you want to be able to supply a material certificate :/
01:16 AM fragalot: it takes 2 days to switch over an SLM machine to a different material, with no guarantee of purity, and a LOT of spare parts
01:16 AM r0n0x: is nylon best choise for SLS or can different/better plastics be used?
01:16 AM r0n0x: that cant be done in filament
01:16 AM r0n0x: all ive seen so far is use w nylon
01:20 AM fragalot: I'm off -- ttyl!
01:30 AM Dave_Elec: what do you guys suggest for 2D cad on linux?
01:38 AM gloops: cad, hmm
01:38 AM gloops: there is nativecam, which i havent used, librecad is already installed, inkscape is a good 2d/vector drawing app
01:38 AM gloops: inkscape is the better drawing tool
01:40 AM gloops: you may have to join open vectors, ive not used it
01:41 AM miss0r: In fear of starting a flame war, especially in here: The windows alternatives for 2D & 3D drawing software is supirior to that of linux
01:41 AM gloops: watch the youtube vids etc, some of these apps take some application to learn
01:41 AM miss0r: And I think it will be a while before that gap is closed
01:41 AM Dave_Elec: i agree..
01:42 AM Dave_Elec: i really enjoyed solidworks back in windows
01:42 AM miss0r: I use MasterCAM 5X & google sketchup. both have their ups'n downs. Together they are a reasonable solution
01:42 AM gloops: there isnt much inkscape cant do for 2d i dont think
01:43 AM miss0r: So I've been told
01:44 AM Dave_Elec: gloops: can i join vectors close to each other with a threshold in inkscape?
01:44 AM gloops: hmm, youll have to have a look i dont use it much lol
01:44 AM miss0r: I have used it once around 4 years ago :]
01:44 AM gloops: a lot of people use it exclusively for 2d drawing for cnc
01:45 AM miss0r: maybe 3 years ago... anywho, I have no idea :D
01:46 AM gloops: yes you can join nodes with a segment or edge in inkscape
01:46 AM Dave_Elec: how
01:46 AM gloops: thing with these apps, and it applies to windows and linux, you have got to learn them, you cant just open them when you want to draw something and expect it to just happen
01:47 AM gloops: takes hours and youll have to rely on youtube and google for information and tutorials
01:47 AM gloops: join #inkscape, they know
01:49 AM gloops: im just getting the hang of one side of blender, i guess it will take 100s of hours to learn it properly, awesome tool when you can use it though
01:51 AM gloops: but when you do get good with it...
01:51 AM gloops: https://www.blenderguru.com/articles/top-10-blender-artworks-january-2018
01:52 AM Dave_Elec: saw it and i was amaized by what it can do
01:53 AM Dave_Elec: I started learning blender but i couldn't get further.. i should start again
01:59 AM gloops: ok in inkscape, select end nodes - click 'join selected endnodes with a new segment' toolbar along top
02:00 AM Dave_Elec: I saw that but i have too much secments to do it manualy
02:01 AM Dave_Elec: i was hoping to set a minimum distance between to points to merge and join them automaticaly
02:01 AM Dave_Elec: solidworks have that option i think
02:01 AM gloops: you might be able to select 2 segments and join them not sure
02:02 AM IchGucksLive: morning from germany
02:04 AM gloops: hello
02:04 AM IchGucksLive: Dave_Elec: what are the 2D off
02:04 AM IchGucksLive: Dave_Elec: images or more shapes outlines real sketch
02:04 AM Dave_Elec: where it came from?
02:05 AM Dave_Elec: they are all splines
02:05 AM Dave_Elec: curves
02:05 AM Dave_Elec: IchGucksLive: real sketch
02:06 AM IchGucksLive: ok so why not using freecad or simly go like i made a video https://www.youtube.com/watch?v=Rv1v5qj7Rek
02:06 AM IchGucksLive: there are so many FREE ways to get good gcode
02:07 AM IchGucksLive: on Linux based systems
02:07 AM IchGucksLive: offline ofcause
02:11 AM IchGucksLive: im off till later
03:10 AM Deejay: moin
03:41 AM selroc: hello
04:51 AM gloops: limit switches wired back up, need to find soldering iron next
04:52 AM XXCoder: yayy now you can come over and install limit switches for me ;)
04:56 AM gloops: haha, limit switches are among the easiest of the baffling electrical things ive done with this
04:56 AM gloops: these are actually home switches anyway, but same thing yeah
04:58 AM XXCoder: ya I do need em. just not sure how to install em
04:58 AM XXCoder: dont want reprap method of placing em
04:58 AM jthornton: morning
04:58 AM gloops: using a breakout board? just the input pins, and a ground, nothing easier
04:59 AM XXCoder: no, alim frame, not sure how to design it so its not done reprap style of smashing into swiotches
04:59 AM gloops: morning jthornton
05:00 AM gloops: ahh, i got lever arm type switchs with rollers, tbh i didnt design anything for them, i just gambled on being able to find some location on each axis where they would work
05:00 AM gloops: which was a close shave on the y axis
05:01 AM XXCoder: yeh reprap design usually also smash into lever arm type switches
05:01 AM gloops: you can probably always get them to sit somewhere, if you make a bracket or something
05:01 AM XXCoder: its supposed to be hit by something passing by it, so it detects before machine smashes into end
05:02 AM gloops: so the switch just takes the first impact of the collision lol
05:04 AM gloops: i cant believe ive been messing about with this wiring for a month, after all that its still just a jumbled box of spaghetti, serious doubts whether anything was gained
05:06 AM XXCoder: needs wire organizer thing
05:06 AM XXCoder: one with cover and ribs
05:06 AM XXCoder: nopt too sure what iuts called
05:07 AM gloops: ill do the next one on an open board and make sides and partitions to fit over the top
05:07 AM gloops: connecting this lot in a small enclosed space is sheer tedium
05:13 AM jthornton: wiring duct
05:13 AM XXCoder: thanks
05:14 AM XXCoder: I have one, havent used it yet, because havent designed electrics box yet
05:17 AM gloops: i would make flexibility a priority for cable thats going in the box, if its tight, i went for heavy duty shielding stuff which is impossible to work with except on longer stretches
05:19 AM gloops: right back to it
05:20 AM Tom_L: morning
05:47 AM IchGucksLive: hi
05:47 AM selroc: hi IchGucksLive
05:47 AM IchGucksLive: Loetmichel: schneesturm 5cm in 15min nicht zu fassen
05:47 AM IchGucksLive: hi selroc im in germany
05:48 AM selroc: pretty close
06:13 AM IchGucksLive: hi heathmanc
06:14 AM IchGucksLive: heathmanc: lots of UK people here
06:14 AM heathmanc: Yup, I'm just kind of temporary though!
06:15 AM heathmanc: Been stationed over here for about 5 years, getting ready to retire back to the states
06:15 AM IchGucksLive: lots of US people here 2
06:15 AM IchGucksLive: ;-)
06:15 AM heathmanc: For sure! Scouting around trying to find somebody good with making bitfiles
06:15 AM heathmanc: I've got an odd combo
06:16 AM IchGucksLive: sounds not that good
06:16 AM IchGucksLive: are you the 5i20 7i43 man
06:17 AM heathmanc: lol, no, I am the 4i69-25, 7i48 or 7i33 man
06:18 AM heathmanc: or a 4i65 7i40 man
06:18 AM IchGucksLive: the 4i69 FPGA or AIN
06:18 AM heathmanc: fpga
06:19 AM heathmanc: right now i need it to work with a 7i48 and 7i37ta, and in the nearest future 2x7i40hv and a 7i37ta
06:20 AM heathmanc: not versed in creating my own bitfiles, and there don't appear to be any out there for the 4i69 ata ll
06:21 AM IchGucksLive: heathmanc: ask pcw he is the man behind mesa
06:22 AM IchGucksLive: but he is at sleep at that tome
06:22 AM IchGucksLive: time
06:22 AM heathmanc: Yup, will try to catch up with him later
06:22 AM IchGucksLive: most he is at 5pm-9pm UK time
06:23 AM IchGucksLive: heathmanc: one Q why that card combination the newer 7i76 woudt give you more comfort
06:24 AM heathmanc: 7i76 is step/dir
06:24 AM heathmanc: i have a single board computer that uses the pci 104 bus
06:24 AM IchGucksLive: the 7i77 is for servos with compplete enncoder work
06:24 AM IchGucksLive: ok
06:25 AM IchGucksLive: it seams you are wright on more power to the mashine
06:25 AM IchGucksLive: and it looks very flexible
06:25 AM heathmanc: and these cards I already have. I have a 6i25, 7i76, 4i65, 5i20, 4i69-25, 7i33, 7i48, 7i37
06:25 AM IchGucksLive: im off Guests arriver here
06:25 AM heathmanc: i have a ton of options
06:26 AM heathmanc: Alright, enjoy!
06:32 AM gloops: getting a nice shock off these input switch wires when everything is powered off
06:53 AM jthornton: ouch
07:10 AM gloops: assume thats a capicitor
07:11 AM gloops: it sparks if i earth it to the frame, wondering best way to discharge it
07:12 AM jthornton: I put some small lamps on my phase converter to drain the caps
07:12 AM gloops: hmm that would have been a good idea
07:15 AM gloops: ill set something up another time to see if a light will drain it off from one switch
07:15 AM XXCoder: or put bigass resistor between so it would drain
07:15 AM XXCoder: in least thats what i remember anyway
07:21 AM gloops: seems to be quite a lot, i thought touching it to the frame would drain it quick but its still live after a few minutes lol, ive heard the resistor talked about before yeah
07:24 AM XXCoder: if I recall it'd have to be huge. like million ohm? so it dont affect much unless powered off it would drain off caps
07:26 AM gloops: not something thats going to be messed about with every day, once wired up shouldnt need touching again unless a wire pulls out, a nice little zap is a bit of a reminder though lol, could do with something
08:01 AM Beachbumpete1: Morning folks ;)
08:20 AM gloops: right thats the X homing again, think ill leave it at that for now
08:32 AM hazzy-dev: gloops: How about using a small NC relay hooked up so that it switches a resistor across the cap terminals when power is shut off?
08:33 AM gloops: i wouldnt know how to do that hazzy, think i have seen something like mentioned before
11:19 AM gloops: nice motor there for someone in the states https://www.ebay.co.uk/itm/Positec-VRDM-3913-50-LWB-Stepper-Motor-6nM-14mm-Shaft/232699215011?
11:19 AM gloops: could be well used though by the look of it
11:25 AM gregcnc: If it had a brake i'd buy it as a spare
11:31 AM gloops: id have had that for my wood lathe scheme, that would hold the spindle steady
11:49 AM gregcnc: what is the valve called that shut off the faucet (kitchen) when you squeeze the spray handle?
11:52 AM gregcnc: I see reference to diverter valves, but they are part of the faucet
12:34 PM IchGucksLive: hi
12:38 PM Tom_L: Beachbumpete1_ what's up?
12:56 PM IchGucksLive: im off Gn8
01:01 PM enleth: ok, so the chinese lubrication system parts arrived today, after two weeks, which I think is extremely fast for an AliExpress order
01:02 PM Tom_L: i'd be interested in what you got
01:02 PM enleth: everything is exactly as ordered, looks nice, parts seem to be well engineered
01:02 PM Tom_L: been looking into some sort of lube system for mine
01:02 PM enleth: machining quality is OK
01:02 PM Tom_L: been manually lubing it for now
01:03 PM Tom_L: probably top notch for chinaco :)
01:03 PM enleth: the manifolds lack Bijur's visual elegance, but they certailny do work
01:04 PM enleth: they're cast properly, it's just the design
01:04 PM Tom_L: was it a 'kit' or did you get separate parts?
01:04 PM Tom_L: got a link?
01:04 PM enleth: all separate parts, my machine is too obscure to have a dedicated kit made for it
01:06 PM Tom_L: plastic tubing?
01:08 PM enleth: nylon, brass and sleeved nylon
01:08 PM enleth: I'll try to make a link list, exporting the order to PDF generates links that are account-specific and won't work for you
01:09 PM enleth: tl;dr all the parts are directly compatible with Bijur 4mm/M8 system
01:10 PM Tom_L: http://www.cambam.co.uk/forum/index.php?topic=4966.0
01:10 PM Tom_L: ran across that
01:10 PM enleth: which is a metric version of the 5/32 tube, 5/16-24 thread system used on Bridgeports
01:10 PM Tom_L: wonder what those fittings are
01:13 PM enleth: Tom_L: https://hackerspace.pl/~enleth/ali-lubrication-order.pdf
01:13 PM enleth: one order view had links that work for anyone
01:14 PM enleth: so I just "printed" it as PDF, the links are clickable
01:14 PM Tom_L: forbidden
01:14 PM enleth: sec
01:15 PM enleth: try now
01:15 PM Tom_L: yup, thanks
01:15 PM enleth: this is all from one seller
01:15 PM enleth: and it turns out that I now have way too many ferrules, compression sleeves and compression nuts
01:16 PM enleth: because every single manifold included those
01:16 PM Tom_L: heh
01:16 PM enleth: but I ordered them separately just in case they're not included
01:16 PM enleth: they were quite cheap and I'll probably find some use for them, so no harm done
01:17 PM enleth: the whole order was $130 shipped
01:17 PM Tom_L: not bad
01:18 PM enleth: enough to re-fit the whole oiling system in a CNC mill with 15 oiling points
01:18 PM enleth: which is almost twice that of a manual Bridgeport
01:19 PM Tom_L: mine has 15 i believe
01:20 PM enleth: the only parts I kept are the pump, obviously, and several brass fittings that screw into the castings because the threaded holes are imperial
01:21 PM Tom_L: i'm planning to use vactra 2 on mine instead of grease
01:26 PM enleth: do you use grease on the ways now?
01:26 PM enleth: why?
01:26 PM Tom_L: i'm using oil right now
01:26 PM enleth: right
01:26 PM Tom_L: vactra 2 is designed for that purpose
01:26 PM enleth: so, what was that about the grease?
01:27 PM Tom_L: the link?
01:27 PM enleth: what?
01:27 PM Tom_L: not sure what you mean
01:27 PM gregcnc: lol
01:27 PM * Tom_L smacks greeniron
01:27 PM Tom_L: and gregcnc
01:28 PM enleth: the parts I linked are for oil, not grease
01:28 PM Tom_L: right
01:28 PM enleth: ah, you mean your link
01:28 PM Tom_L: that's what i'm planning on
01:28 PM Tom_L: yeah my link was just showing a way to access them
01:29 PM enleth: I didn't even read the text - is that guy pushing grease into ball nuts?
01:29 PM Tom_L: i don't care what he puts in the tubes :)
01:29 PM Tom_L: i think so
01:29 PM gregcnc: linear rail trucks
01:30 PM enleth: ah, *those* fittings
01:30 PM enleth: I looked at the brass ones on the ball nuts
01:30 PM Tom_L: https://www.hiwin.com/pdf/lubricating_instructions.pdf
01:30 PM Tom_L: apparently you can access them in different places
01:31 PM gregcnc: I didn't notice the brass tube
01:32 PM enleth: the blue sleeve fittings are actually sold as "air fittings" on AliExpress
01:32 PM gregcnc: push connects
01:32 PM enleth: https://aliexpress.com/wholesale?catId=0&initiative_id=SB_20180322102953&SearchText=air+fitting
01:33 PM enleth: ok, "push fitting" works too
01:33 PM enleth: but for oil, I'd go with the Bijur-like system I bought
01:34 PM Tom_L: wonder if fastenal or some place carries those
01:34 PM enleth: sure it does, but you don't want to know the price
01:34 PM Tom_L: i'm sure
01:34 PM gregcnc: if you only need one or two, otherwise places want to sell bags of 10
01:35 PM gregcnc: i've bought from mcmaster
01:35 PM Tom_L: plastic tube should be ok i'd think
01:35 PM Tom_L: nylon
01:36 PM gregcnc: many machines have plastic tubing
01:36 PM Tom_L: the old ones had routed brass
01:36 PM gregcnc: many new machines do as well
01:36 PM gregcnc: just depends where they are routed
01:37 PM Tom_L: wonder how you'd do it on a moving ballscrew nut
01:37 PM Tom_L: i guess attach the other end to what the nut is attached
01:37 PM Tom_L: have more than one lube point
01:38 PM Tom_L: could run the nylon tube thru the dragchain i guess
01:39 PM slipalong: Guy's need a bit of config assistance
01:39 PM Tom_L: we're good at that
01:39 PM slipalong: Im have a manually generated config with backlash and homing configured and working
01:39 PM gregcnc: normal machine stuff, make sure it won't snag, no excessive bends, protection from damage/chips....
01:40 PM Tom_L: yeah
01:40 PM Tom_L: is it common to do that though?
01:40 PM gregcnc: my lathe has it
01:40 PM slipalong: Im trying to add a halui extra panel to axis
01:40 PM Tom_L: thru the drag chain?
01:41 PM slipalong: it will have a real spindle speed displaye
01:41 PM gregcnc: I'd have to take a look as i don't remember how they did it. Travels are small so it may just hang there
01:41 PM slipalong: I am trying to all the example compnent
01:41 PM Tom_L: slipalong, http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/sherline/
01:41 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/screenshot.png
01:41 PM Tom_L: will get you that
01:42 PM slipalong: Thanks Tom In having a looknow
01:42 PM Tom_L: look at display.xml, postgui.hal
01:42 PM Tom_L: for most of the side pannel
01:43 PM Tom_L: i think
01:43 PM Tom_L: :)
01:44 PM Tom_L: some in the main .ini
01:46 PM slipalong: wow this is complicated!
01:46 PM Tom_L: no not really
01:46 PM Tom_L: break it down in pieces
01:46 PM Tom_L: display shows the widgets, the rest glues it together
01:46 PM enleth: Tom_L: I bough two runs of nylon tubing sleeved in a steel spring to deliver oil to moving assemblies
01:47 PM slipalong: what happening is that unless I comment out pyvcp.spindle-speed in the post guy hal I get an sere that it cant find the pin
01:47 PM slipalong: also if I comment that line out I dont get the extra panel at the side of axes
01:47 PM slipalong: but then it runs
01:47 PM enleth: Tom_L: brass is still used when oil needs to be dripped onto something and the end of the tube has to hang in mid-air above
01:48 PM Tom_L: yeah
01:48 PM Tom_L: slipalong, look at the first line of postgui.hal
01:48 PM enleth: otherwise it's nylon
01:48 PM slipalong: where do you define the pyvcp? though it would be on the ini file
01:49 PM Tom_L: postgui.hal
01:49 PM Tom_L: i think
01:49 PM enleth: Tom_L: that chinese seller also had aluminum tubing, but I have no idea what it's for that brass cannot handle
01:49 PM Tom_L: i've slept since then
01:49 PM Tom_L: i wouldn't use aluminum i don't think
01:50 PM enleth: brass tubing is actually cheaper, so it's not about the price
01:54 PM slipalong: Tom, where in the INI file do you tell Axes to display the pyvcp on the UI?
01:55 PM slipalong: I think my postgui hal is ok but it cant find the pyvcp.spindle-speed signal/pin to connect the rpm to
01:55 PM Tom_L: [DISPLAY]
01:55 PM Tom_L: PYVCP = display.xml
01:56 PM slipalong: that what I missed THANKS!!
02:03 PM enleth: Tom_L: https://i.imgur.com/xuVEB4Z.jpg
02:04 PM Tom_L: nice
02:05 PM gregcnc: https://chicago.craigslist.org/nch/tls/d/new-bridgeport-mill-y-table/6522477457.html
02:08 PM gloops: well, got the X homing again today, not much left at all now to do
02:36 PM JT-Shop: what was wrong with the X
02:39 PM gloops: nothing really, ive had it down to re-wire and made some stronger pulley inserts for the screws - m8 bolts now
02:39 PM gloops: or the pulleys are now fixed with m8 bolts, not the tiny grubscrews i had before
03:18 PM Deejay: re
03:28 PM Connor: Hey, what do you all use to clean surface plates? I've seen suggestions of WD40, Denatured Alcohol. Formula 409...
03:28 PM CaptHindsight: yes
03:29 PM CaptHindsight: not much is going to swell or dissolve the granite
03:29 PM CaptHindsight: whatever cleaners and solvents remove what is on its surface
03:30 PM Connor: Yes, but abrasive cleaners.. need to be avoided at all costs. Ones that leave a film too.
03:30 PM CaptHindsight: and not leave its own residue
03:30 PM CaptHindsight: yes, obviously not abrasives
03:30 PM CaptHindsight: do not belt sand before use!
03:31 PM CaptHindsight: gregcnc: how much backlash does anew Bridgeport typically have?
03:32 PM gregcnc: no idea, but who buys a new bridgeport and converts to cnc?
03:33 PM gregcnc: well ballscrew I guess
03:35 PM CaptHindsight: looks like he did, surprisingly
03:35 PM Connor: I think they say .004 to .006 is typical.
03:35 PM CaptHindsight: I must have 0.1" in the X
03:36 PM gregcnc: yeah I thought you mentioned before, price seems fair
03:36 PM CaptHindsight: yeah
03:37 PM CaptHindsight: might be worth just holding on to
03:37 PM CaptHindsight: my BP is pretty worn
03:37 PM CaptHindsight: I saw a headless BP up in Milwaukee for a few hundred
03:37 PM Tom_L: cnc it
03:37 PM gregcnc: decapitated
03:37 PM CaptHindsight: still had signs of oil marks on the ways
03:38 PM CaptHindsight: no desire to have a series 1 cnc here
03:39 PM CaptHindsight: J head
03:40 PM CaptHindsight: I got this one from an auction for $800
03:41 PM CaptHindsight: somebody used the table for hole drilling practice and then welded up the holes
03:41 PM Connor: Ugg.
03:41 PM Connor: That's just sad.
03:41 PM Tom_L: awesome
03:41 PM Tom_L: someone should use him for target practice
03:41 PM CaptHindsight: how do you not know when a 3/4 end mill has hit the table?
03:42 PM Connor: I have a something like that on my table too..
03:43 PM Tom_L: i almost broke my vise in yesterday :=)
03:43 PM CaptHindsight: heh
03:43 PM Tom_L: i changed the sub that sends it now now
03:43 PM CaptHindsight: "signs of use"
03:44 PM Tom_L: when you go from a higher work offset to a lower one, before Z would move first
03:44 PM Tom_L: now i issue G28 Z0 instead of G0 Z0
03:44 PM Tom_L: normally it didn't matter because i only was using a single offset
03:45 PM Tom_L: so i would move z first thinking it would always go up
03:45 PM CaptHindsight: "Reciprocating variable speed saw by Tool Shop #241-9848 - $20" does that mean they give you $20 and the the saw? :)
03:46 PM CaptHindsight: i think Tool Shop is the HF quality house brand at Menards
03:46 PM Tom_L: my friend bought a cheapo bandsaw a while back since he's retired now and he likes it better than the big commercial one he had at the shop
03:47 PM Tom_L: forget the brand
03:48 PM CaptHindsight: I tried a HF bandsaw for about an hour before the blade started slipping
03:48 PM Tom_L: it wasn't _that_ cheapo
03:50 PM gloops: tighten the blade till the plastic tensioning handle snaps then get some molegrips on the shaft, blade wont slip
03:50 PM CaptHindsight: reminds me to go to ACE for crafstman swap
03:50 PM Tom_L: yeah i nearly forgot they carried the stuff
03:53 PM gloops: was a good motor for sale near virginia, bet its ended now

04:03 PM Tom_L: 4 days left to bid
04:05 PM gloops: well yeah, dont suppose that many people are looking for those either
04:09 PM CaptHindsight: it looks to me like they start the bids low and keep them short
04:12 PM gloops: trump on TV lol, 60 billion in tariffs on china - as punishment for years of stealing american tech
04:14 PM CaptHindsight: yeah, was reading it earlier
04:15 PM gloops: china has responded - we wont back down
04:16 PM gloops: dji closes 725 down
04:18 PM renz: 'stealing'
04:19 PM renz: in modern r&d, theyre often providing most of the tech
04:20 PM gloops: well, you get it back yes, at a very low price
04:22 PM Tom_L: long as i get my stuff from aliexpress...
04:24 PM CaptHindsight: just more distraction
04:24 PM CaptHindsight: Russia investigation, hey look over here tariffs
04:25 PM CaptHindsight: sexual harassment, look over here taxes
04:25 PM gloops: i think it only applies to heavy iron and steel, thats how i read it anyway
04:25 PM Tom_L: i really wonder what the aliens think of this planet :)
04:25 PM CaptHindsight: bunch of monkeys, move on
04:27 PM gloops: theres probably a space beacon nearby signalling that this planet isnt worth visiting and the intelligent life isnt going to survive long enough to be worth making contact with
04:28 PM CaptHindsight: nice rock and lots of H2O
04:43 PM CaptHindsight: it's interesting, I've moved to mostly working with synthesizing DNA and mass producing it
04:43 PM CaptHindsight: lots of overlapping patents
04:44 PM CaptHindsight: but not many active projects to use it for cures
04:44 PM CaptHindsight: seems the FDA has put up roadblocks for testing on patients
04:44 PM CaptHindsight: so the Chinese are leading the way
04:46 PM CaptHindsight: expensive treatments no problem, cures, not so much here
04:46 PM CaptHindsight: more money in treatments
04:50 PM mozmck: Any real cures are buried if they don't cost $$$$
05:07 PM gloops: actually this does affect a lot of stuff, electronics and apparel
05:14 PM fragalot: hi
05:16 PM gloops: evening
05:16 PM BeachBumPete: Hey Frag
05:16 PM fragalot: received the epoxy today
05:16 PM fragalot: but not the vacuum pump yet because the supplier had some ... inventory issues
05:16 PM fragalot: which has resulted in a free significant upgrade, so i'm not complaining :-)
05:17 PM gloops: sometimes works out like that, nice one
05:17 PM BeachBumPete: \o/
05:18 PM gloops: i hope youve got the epoxy somewhere where you can keep looking at it lol
05:18 PM fragalot: what do you mean?
05:18 PM gloops: well, thats what i normally do with purchases
05:19 PM fragalot: put it on display on a shelf? :P
05:19 PM gloops: this is going to be the bog one fragalot, lot of pressure on here
05:19 PM gloops: bog = big
05:20 PM fragalot: what pressure? :P
05:20 PM fragalot: I'm the alpha male. you can't pressur eme!
05:20 PM gloops: i think you can do it actually
05:21 PM fragalot: yeah it will just take time :)
05:21 PM gloops: many would have doubts over you, but i think youve got it in you
05:23 PM Deejay: gn8
05:56 PM enleth: sooooo, I'm trying to pull the backplate off of the new lathe
05:56 PM enleth: I'm not even sure what kind of spindle nose it has
05:57 PM enleth: the previous owner swapped chucks on this one backplate
05:59 PM enleth: it's held by four bolts, almost certainly imperial size judging by the nut width (a smidge over 15mm, so probably 5/8"), that grab onto a relatively thin plate with a knurled edge, with elongated holes that allow the plate to be rotated about 10 degrees and moved over the nuts
06:00 PM enleth: there are also two funny nuts threaded onto two bolts protruding from the backplate towards the headstock, they look kinda like some sort of an ejection mechanism, but I'm not sure
06:04 PM enleth: https://imgur.com/7mohRQU bolted on
06:04 PM zeeshan: anyone work with linear bearings here?
06:04 PM enleth: https://imgur.com/0deCyC8 nuts loosened, plate twisted and slid over the nuts
06:05 PM enleth: https://imgur.com/b8CFh0W pockets in the plate
06:05 PM enleth: the chuck won't budge
06:05 PM enleth: I tried smacking it gently with a mallet, still won't budge
06:06 PM enleth: what's the correct next step to pull it off of there?
06:09 PM BeachBumPete: interesting
06:09 PM BeachBumPete: is there some kind of spanner to hold the backing plate/whatever it is?
06:10 PM enleth: nope
06:10 PM enleth: the thick ring behind the chuck is completely smooth
06:10 PM enleth: the thin plate is knurled so that it can be twisted by hand
06:10 PM enleth: judging by the bolt pattern - four instead of three or six - this might be a DIN 55027 spindle
06:10 PM BeachBumPete: have you tried to hold onto the gnurled part and spin the chuck the other way? IT LOOKS like a bolt on chuck body tho
06:11 PM enleth: the chuck won't move anywhere
06:11 PM enleth: the plate is now sliding freely back and forth along the nuts
06:11 PM enleth: any torque applied to it will transfer to those nuts
06:11 PM BeachBumPete: like in the slots movement or axially?
06:11 PM enleth: which are on bolts that, I presume, are connected to the spindle
06:12 PM enleth: tl;dr the plate is completely loose in there now
06:12 PM enleth: if it could phase through the spindle, it would fall off
06:12 PM enleth: OK, I am almost sure this is a DIN 55027 spindle
06:12 PM enleth: so, how does one get a DIN 55027 backplate off the spindle?
06:15 PM enleth: do I just bang on it some more? or try to apply leverage to the bolts against the headstock?
06:16 PM BeachBumPete: http://www.chaski.org/homemachinist/viewtopic.php?t=73851
06:16 PM BeachBumPete: not sure if that is the same situation
06:17 PM enleth: this is for a camlock I think
06:18 PM BeachBumPete: I had a D1=4 and it did not look anything like that
06:18 PM enleth: oh well
06:19 PM enleth: it's definitely designed so that the chuck pulls off of the spindle with the bolts and nuts connected
06:19 PM BeachBumPete: looking at your photos how did you get the gnurled plate from behind the smooth plate to up against the headstock?
06:20 PM enleth: look at the last photo - the plate has bean-shaped pockets with a larger hole on one end
06:20 PM enleth: after loosening the nuts, I could twist it slightly and pull it over the nuts towards the headstock
06:20 PM enleth: it is now completely loose in there
06:20 PM BeachBumPete: so if that is the case it would SEEM to be that it is some sort of cylindrical clamp
06:20 PM enleth: and I can see the thick flange it was bolted against has big holes for the nuts to pass through
06:20 PM BeachBumPete: so if you have it off the slots and up against the headstock whatever it was holding is now loose
06:21 PM enleth: yes, technically the chuck/backplate assembly is now unbolted
06:21 PM enleth: but it's still stuck on there
06:21 PM BeachBumPete: it is probably some sort of taper mount with a collar to lock it in
06:21 PM enleth: and I'm not sure where to apply force to not break anything
06:22 PM BeachBumPete: I would try to use a rubber mallet on the shiny bit in there carefully with some plywood over the ways and see if you can gently tap it off
06:22 PM enleth: so far applyin a rubber mallet failed miserably
06:22 PM BeachBumPete: perhaps try a piece of wood carefully?
06:23 PM BeachBumPete: there does not seem to be any means of locking it so I kinda doubt it would be threaded internally but I suppose anything is possible
06:23 PM BeachBumPete: personally I have never seen one quite like that
06:23 PM zeeshan: https://photos.app.goo.gl/1eNPz66dfnllU3wR2
06:24 PM zeeshan: does anyone know if this grease fitting can be turned 90 degrees towards the hole
06:24 PM zeeshan: its a m6x.75 thread
06:24 PM zeeshan: i dont know how youre supposed to do that
06:24 PM BeachBumPete: https://www.vanommen.nl/en-us/clamping-of-workpiece/chucks/bison-3-jaw-self-centring-scroll-chuck-steel-type-85.422
06:26 PM BeachBumPete: that shows the 55027 but its a complete chuck with that backplate setup included
06:27 PM BeachBumPete: zeeshan looks like just a thread in type but hard to tell from the photo. Some do have a pivot on the nozzle
06:27 PM zeeshan: i was honestly thinking this was the pivot style
06:27 PM zeeshan: but its frigging fixed man
06:27 PM BeachBumPete: you could spot face the surface to allow more rotation of the fitting
06:27 PM zeeshan: tehyve assembled it at the shop
06:27 PM zeeshan: i was thinking of asking them to put a washer in between
06:28 PM BeachBumPete: or that
06:28 PM zeeshan: at least i dont think im going crazy!
06:28 PM zeeshan: cause you confirmed they do exist with a pivot
06:29 PM BeachBumPete: at least I could have sworn I have seen them like that
06:31 PM Tom_L: what's up?
06:32 PM BeachBumPete: Hey Tom
06:32 PM Tom_L: did you see my test chamfer part?
06:32 PM BeachBumPete: me?
06:32 PM Tom_L: yeah
06:32 PM BeachBumPete: no
06:32 PM enleth: https://i.imgur.com/IQxkxHY.jpg ok, got it off
06:32 PM enleth: needed a bigger mallet
06:33 PM BeachBumPete: so I was right ;)
06:33 PM Tom_L: stuck with grease
06:33 PM BeachBumPete: glad you got it sorted man
06:33 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Vise_parts/Speedhandle2.jpg
06:33 PM BeachBumPete: sweet
06:33 PM Tom_L: a little deeper than i'd like but i didn't test it on anything
06:33 PM BeachBumPete: damn I need to break down and make one of those
06:33 PM Tom_L: just calculated
06:33 PM Tom_L: :)
06:34 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Vise_parts/Speedhandle_fit2.jpg
06:34 PM BeachBumPete: drilled or plunged the corners?
06:34 PM Tom_L: i drilled the holes first
06:34 PM BeachBumPete: sweet
06:34 PM BeachBumPete: you need to engrave your name in it ;)
06:34 PM Tom_L: all 1 program
06:34 PM Tom_L: top and bottom
06:34 PM Tom_L: i still could
06:35 PM BeachBumPete: how did you do the other side?
06:35 PM Tom_L: was sorta testing out the mods i did to my post too
06:35 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Vise_parts/Speedhandle_profile.jpg
06:35 PM Tom_L: the flat clamp marked where it should butt up against when flipped
06:35 PM BeachBumPete: ah so just reposition the clamos
06:35 PM Tom_L: the right screw stayed
06:36 PM Tom_L: just bolts on P1
06:36 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Vise_parts/Speedhandle1.jpg
06:36 PM BeachBumPete: nice is that a 2 or 4 flute?
06:36 PM Tom_L: P2 i left the right bolt and clamped
06:36 PM Tom_L: 2
06:37 PM Tom_L: pretty happy with the results
06:37 PM BeachBumPete: why couldn't you just put two clamps and remove both screws?
06:37 PM Tom_L: no need
06:37 PM Tom_L: the right hole will get drilled and tapped for a handle
06:37 PM BeachBumPete: ah ok
06:37 PM BeachBumPete: I was assuming you were going to do another hex
06:38 PM Tom_L: did it all at once with Op stops
06:38 PM BeachBumPete: I like those
06:39 PM BeachBumPete: We pulled the trigger on a nice CR Onsrud 5x12 CNC flatbed router with toolchanger today.
06:39 PM Tom_L: nice
06:39 PM Tom_L: what control?
06:39 PM BeachBumPete: We also bought a Weinig 6 head moulder with a ton of extra heads, spare parts, and the little optical comparator setup machine for the knives
06:40 PM BeachBumPete: I think it is an A&M
06:40 PM BeachBumPete: it is a used machine
06:40 PM BeachBumPete: its located in Oregon
06:40 PM BeachBumPete: I MAY be flying out to inspect it before we make final payment
06:41 PM Tom_L: still hooked up?
06:42 PM BeachBumPete: yeah
06:42 PM BeachBumPete: it LOOKS pretty nice in the photos
06:42 PM BeachBumPete: 12 tool carousel changer
06:42 PM BeachBumPete: it even has a 9 head drilling spindle in it
06:42 PM BeachBumPete: it supposedly has an aggregate tooling head setup but I could not see how
06:43 PM BeachBumPete: been watching lot of this guy Lars Christensen lately ;)
06:46 PM BeachBumPete: We did not get that HAAS VF4 we made the offer on apparently somebody wanted it more than we did ;)
06:50 PM Tom_L: what about the printer?
06:52 PM BeachBumPete: the printer is basically a done deal. ALL of these machines are going to be in one large finance deal. We are just trying now to make the deals on each of them individually and send deposits etc. Once we have everything in place the number crunchers will do the rest.
06:52 PM BeachBumPete: they also want us to inspect each one individually or have a tech inspect them.
06:55 PM skunkworks: is this thing on?
06:55 PM Tom_L: no
06:55 PM skunkworks: huh - cool
06:55 PM BeachBumPete: LOL
06:55 PM BeachBumPete: Hey Skunkie
06:55 PM Tom_L: go back to your corner :)
06:56 PM skunkworks: irssi client - text mode. my linux assimilation is complete..
07:03 PM skunkworks_: hi BeachBumPete how is Florida?
07:04 PM BeachBumPete: Florida is pretty damn nice man ;)
07:04 PM skunkworks: oops - I mean 'hi BeachBumPete - how is Florida?
07:05 PM BeachBumPete: they have been having some good sized brush fires near me lately for some reason tho.
07:06 PM BeachBumPete: Yesterday I watched one from the road while I drove home it was nowhere near me but you could see it really good coming over the Stuart bridge
07:06 PM skunkworks: My cousin lives in florida? do you know her?
07:06 PM skunkworks: (I am kidding)
07:06 PM BeachBumPete: hehe
07:06 PM BeachBumPete: yeah man we go way back
07:50 PM gregcnc: I just got my F360 renewal notice 40usd/month 310/yr
07:52 PM BeachBumPete: I wonder if you could draw in fusion360 as you would draw say a wall of cabinets in autocad 2d?
07:53 PM gregcnc: not sure haven't used it much at all.
07:54 PM BeachBumPete: I was just playing with it and I was trying to determine how to create infinite lines which is typically how I create construction geometry in 2d CAD
07:54 PM BeachBumPete: I use those and offsets a LOT in my drawing to setup distances quickly
07:55 PM BeachBumPete: but I know fusion works quite differently in general
07:55 PM gregcnc: right you wouldn't be doing things that way in any solid model
07:55 PM zeeshan: how are you comparing autocad to fusion!!!!!!!!!!!
07:55 PM gregcnc: offest are common though
07:56 PM BeachBumPete: I am not comparing them
07:56 PM zeeshan: we use autocad to view drawings at work
07:56 PM zeeshan: and create schematic drawings
07:56 PM BeachBumPete: I was just wondering how hard it would be to use it to try to create cabinet drawings
07:56 PM zeeshan: a main assembly drawing in autocad is like 60mb
07:57 PM zeeshan: do u mean drawings like this:
07:57 PM zeeshan: http://www.youngarchitectureservices.com/Z-KITCHEN%201.jpg
07:57 PM BeachBumPete: I am using autocad clone currently and it is fine but it would be NICE to be able to take those drawings and try to extrude things creating 3d models somehow
07:57 PM zeeshan: thats the beauty of inventor and autocad
07:57 PM BeachBumPete: yeah something like that
07:57 PM zeeshan: since theyre owned by the same company
07:57 PM zeeshan: you can copy your autocad stuff and paste it in inventor
07:58 PM zeeshan: you'd need to constrain, but even if you didnt, it'd let you extrude
07:58 PM BeachBumPete: well you CAN just export your 2d as a DXF or DWG and import it
07:58 PM zeeshan: its really useful cause the company started off using autocad 3 decades ago
07:58 PM BeachBumPete: often that is how I create my 3d models
07:58 PM zeeshan: it never worked good for me in solidworks
07:58 PM BeachBumPete: draw the basic design in 2d and then import and extrude it
07:59 PM zeeshan: like each line element was not joined
07:59 PM BeachBumPete: but that was with simple shapes generally
07:59 PM zeeshan: when i paste it in inventor its all joined
07:59 PM zeeshan: it just doesnt know whats a vertical line or horizontal line
07:59 PM zeeshan: dimensions also carry over
07:59 PM BeachBumPete: a cabinet design while not complex is not the same kind of single body design
08:00 PM BeachBumPete: I watched Lars build a simple cabinet in F360 and it worked fine but it did not appear to be something you could generate quickly
08:00 PM zeeshan: i think it could be setup so all the leg work is done upfront
08:00 PM zeeshan: and in the future its just manipulating parameters
08:01 PM gregcnc: I think ideally youd make parametric models that would have a lot of things update witha few dimensions changes
08:01 PM BeachBumPete: yeah that would be nice too
08:01 PM zeeshan: what would change between one cabinet and another?
08:01 PM zeeshan: someone might possibly want a different style door right?
08:01 PM gregcnc: dunno
08:01 PM gregcnc: custom vs cookie cutter
08:01 PM zeeshan: or handles
08:01 PM BeachBumPete: most generally just sizes
08:01 PM zeeshan: ahh
08:01 PM zeeshan: that is a lot easier in 3d imo
08:01 PM zeeshan: cause of parametric
08:02 PM gregcnc: but that also depends how the shop is setup
08:02 PM gregcnc: if prints like that really matter
08:02 PM BeachBumPete: there are programs such as 2020 cabinet design that do that
08:02 PM BeachBumPete: you basically draw each wall in a 2d setup
08:02 PM BeachBumPete: mostly when i say draw you are selecting basic cabinet styles
08:02 PM BeachBumPete: and inputting them
08:02 PM BeachBumPete: then you change them to your needs
08:02 PM gregcnc: i worked at a place where 80% of the stuff them made was one drawing with values spit out from a spreadsheet
08:03 PM gregcnc: after i made the spread sheet
08:03 PM BeachBumPete: once you have that however you can then create a 3d model of the whole installation
08:03 PM BeachBumPete: this can be sort of toured thru in a VR style view
08:03 PM gregcnc: sales tool?
08:03 PM BeachBumPete: I wonder if something like that could be accomplished in F360
08:04 PM BeachBumPete: well it is generall a sales tool but it also generated the 2d drawings for either ordering or creating the cabinets
08:06 PM BeachBumPete: https://www.cronsrud.com/pro_series.html
08:07 PM BeachBumPete: This is basically the machine we are buying for the shop. Ours is a few years old but it is essentially the same machine
08:08 PM BeachBumPete: if you click on the additional photos the bottom left one is most like the one we are buying,
08:08 PM BeachBumPete: Looking forward to using this thing.
08:14 PM andypugh: enleth: That style of spindle seems to be like a half-hearted D1 type.
08:15 PM andypugh: Though I have to say that I don’t intuitively undestand the D1 eccentric clamps. Apart from anything else they seem to turn the wrong way.
08:44 PM dioz: any of you guys got some good youtube channels with regards to fabrication?
08:44 PM dioz: welding, etc.
08:58 PM BeachBumPete: that guy weldmonger is pretty good I think
09:11 PM dioz: right on
09:13 PM dioz: what are those measuring gauges called that look like calipers?
09:17 PM dioz: vanier caliper?
09:18 PM dioz: trying to find analog ones on amazon but no dice
09:27 PM jdh: a dial caliper?
09:27 PM dioz: yah
09:28 PM jdh: lots on amazon
09:28 PM dioz: i think i was missing the word "dial"
09:28 PM dioz: thnx
09:45 PM enleth: andypugh: I don't think there's anything eccentric in this mount
09:45 PM enleth: andypugh: it's just straight threaded rod pull, parallel to the spindle axis
09:46 PM enleth: the twist plate is there only to provide some means of putting the nuts onto the threaded rods before seating the chuck
