#linuxcnc Calendar

01:11 AM IchGucksLive: later need to do some construction now
01:42 AM Laminae: roycroft: so i finally figured out how all those people in the forums were controling router speeds to cut alum
01:55 AM roycroft: using those external router speed control units?
01:56 AM Laminae: Yeah, superpid
01:56 AM roycroft: they don't work very well
01:56 AM roycroft: and when you slow down the router it gets really really hot
01:56 AM roycroft: so be careful if you do that
01:57 AM Laminae: Still thinking i'm just going to roll with the router but it did seem interesting
01:58 AM roycroft: it's your ears :)
01:59 AM Laminae: Sorry, what? I can't hear you
02:01 AM gloops: laminae you control the speed from linuxcnc and the g-code with a vfd
02:02 AM gloops: when i get my spindle connected again, ill make a vid with the spindle running, and then a hitachi m12 router - see which you think is best for noise
02:03 AM Laminae: gloops: the original question was how so many people were cutting 1/4in and 1/2in alum plates using a dewalt 611, i sent a few people private messages and while some of them are just setting their routers to the lowest setting, several people are using supepid
02:03 AM gloops: oh i see only saw the last few comments
02:04 AM Laminae: I would really like to choose the vfd spindle option, but i think roy makes a good point
02:04 AM Laminae: I'm in the no mans land of available products
02:05 AM gloops: water cooled spindle seems best option for slow cutting speeds
02:05 AM Laminae: And really, this isn't a mill, it's a router and trying to treat it like a mill will probably end in disappointment
02:06 AM Laminae: seems like for a lot of the applications i'm interested in 13k to 20k is pretty good
02:06 AM gloops: well, the only difference between a mill and a automated router is rigidity, bearings etc, it will cut ally if you make it strong enough
02:07 AM Laminae: I know the frame is rigid enough to do it, but requires more steps
02:08 AM roycroft: wait, is that dewalt router variable-speed?
02:08 AM gloops: ive watched mine as ive made it, i studied the theory of gantry design for some time
02:09 AM gloops: putting lots of force by hand on the spindle mount, you can see where the forces take effect
02:09 AM roycroft: laminae: you need to bypass that router's built-in variable speed control if you want to use an external speed controller or you will burn up the built-in circuitry
02:10 AM Laminae: If there were a simple one solution in the sub 500 dollar category that would allow me to control the spindle through lcnc and have speed options for hdpe, alum and wood i would be all over it but as roy said, one thing won't do all of those
02:10 AM Laminae: So i'm thinking i need to make a choice
02:10 AM gloops: ALL the bearings take it, you can see the X bearing mountings trying to lift, wouldnt believe it with a 120lb gantry but they do
02:11 AM Laminae: The user reported (slightly suspect) claims that at 60lbs there is 1.5mm frame deflection
02:11 AM Laminae: Which is supposedly relatively stiff (i don't really know to be honest)
02:11 AM gloops: 60lbs where? on the cutter?
02:12 AM gloops: every inch you go down the z - add 40lbs, leverage
02:12 AM Laminae: Yes, that's without a spindle mounted, another reported 2mm at 50lb
02:12 AM Laminae: So *shrug*
02:12 AM roycroft: get the machine
02:12 AM gloops: you will be able to reduce that
02:12 AM roycroft: get the router
02:13 AM roycroft: give it a go
02:13 AM roycroft: and you'll figure out what works for you and what doesn't
02:13 AM roycroft: make adjustments as needed
02:13 AM Laminae: I'm raising your blood pressure
02:14 AM gloops: lol
02:14 AM roycroft: mine?
02:14 AM Laminae: It's a moot point really because i've already orderd it haha
02:14 AM Wolf__: figure out what works like 0.1mm doc lol
02:15 AM roycroft: you're not affecting that at all
02:15 AM Laminae: ah good
02:15 AM roycroft: there's an orange-skinned person who occasionally does
02:15 AM gloops: my suggestion 2.2k spindle/vfd £200, full control, quiet, powerful, wont overheat
02:15 AM roycroft: but other than that i'm pretty chill
02:15 AM roycroft: gloops: i suggested that as well
02:16 AM roycroft: but you can't run those things really slowly
02:16 AM Laminae: that was what i was wanting to do but sadly i'm stuck with 110v wall outlet
02:16 AM roycroft: you can get a lower power spindle
02:16 AM roycroft: here's something that most folks don't seem to get
02:17 AM gloops: i think you can get vfd with 110v input, mine accepts it in fact
02:17 AM Laminae: 1.5kw was the option i found
02:17 AM gloops: 1.5 is fine
02:17 AM roycroft: a universal motor cannot magically generate more horsepower than an induction motor using the same amount of power
02:18 AM roycroft: the reason that the universal motors list higher hp at a given amperage than an induction motor is because the universal motor manufacturers lie
02:18 AM roycroft: don't look at hp
02:18 AM roycroft: look at amps
02:18 AM roycroft: you can buy a spindle with the same amperage rating as your router
02:18 AM roycroft: and it will have approximately the same amount of power
02:19 AM Wolf__: where do they get the HP rating from, math not counting losses?
02:19 AM roycroft: 3 phase motors are actually a bit more efficient than single phase motors
02:19 AM roycroft: their arses, i think
02:19 AM Laminae: Won't i end up melting hdpe though? i think that was what you were cautioning me against
02:19 AM gloops: with a machine frame likes this and stepper motor drive, you arent going to be ploughing through aluminium like a bridgeport
02:19 AM roycroft: that is a different concern
02:19 AM gloops: your going to be taking light passes with small cutters
02:20 AM roycroft: but i also suggested you might buy an unpowered spindle, a separate motor, and set up some sheaves to adjust the motor to spindle speed ratio
02:20 AM roycroft: that way you can still use a vfd and let linuxcnc control it
02:20 AM roycroft: but you can set it up to use two speed ranges
02:21 AM roycroft: you set it manually to one range or the other as part of your setup for making a part
02:21 AM roycroft: you can set it to a rage of, say, 80-2000rpm, and another range of, say, 10,000-24,000 rpm
02:21 AM roycroft: i haven't done the math - i'm just making up the numbers as an example
02:22 AM roycroft: but if you do that you can use the same spindle for both speed ranges, with only the need to move a belt to change ranges
02:22 AM roycroft: linuxcnc can handle all the speed control within a range
02:22 AM roycroft: and you can still run your motor at safe speeds so that it won't overheat and let the magic smoke out
02:23 AM Laminae: I think that makes a lot of sense and it's a very good option but i'll likely need to have something functional in the mean time while i figure that out
02:23 AM roycroft: which is why i said to just get the router and be done with it
02:23 AM Deejay: moin
02:23 AM roycroft: hat gets you going
02:24 AM roycroft: and when you're ready to upgrade, it will make a nice hand-held router for other projects
02:24 AM Laminae: I think we're both just agreeing with eachother a lot haha
02:24 AM roycroft: i would not mess with trying to do speed control of the router with linuxcnc though
02:24 AM roycroft: just get it, install it, and use it as is for a while
02:25 AM archivist: found an interesting article on frame stiffness in a 1963 book yesterday, lots of additional webs
02:27 AM Wolf__: ’60s tech, make it heavy and out of iron? =]
02:27 AM Laminae: Or pure asbestos
02:27 AM Wolf__: thats just fire proofing
02:28 AM Laminae: The navy made blankets out of asbestos for subs for that simble reason
02:28 AM Laminae: simple*
02:29 AM Laminae: Probably bit awkward once the health implications became apparent
02:29 AM Wolf__: lol just a bit
02:31 AM archivist: better stick to cutting cheese <Laminae> The user reported (slightly suspect) claims that at 60lbs there is 1.5mm frame deflection
02:32 AM Wolf__: seeing that I pulled a mill cutter out of a collet that probably had 1500lb of pulling force, when cutting some aluminum
02:33 AM Wolf__: 60lbs causing deflection should be fine lol
02:33 AM Laminae: I like my cheddar milled, not stirred
02:35 AM gloops: the important thing is - 60lbs WHERE
02:36 AM archivist: cutting forces can be disconcerting
02:36 AM gloops: 60lb at y rail height is a totally different matter to 60lbs on the cutter
02:36 AM Laminae: was on cutter, brb
02:36 AM gloops: because you have to add a crow bar to the cutter to realise the forces it will create
02:43 AM pink_vampire: morning
02:43 AM gloops: to get rid of the remaining deflection in mine, id need square rails, wider x footprint, 60x60 box section for the y cross members, 3/4 inch front plate on the z
02:44 AM gloops: but i think im ok with it as it is
02:47 AM gloops: i wonder about the rigidity of some of these alu profiles, you hold one, yeah seems stiff as hell, you cant make it bend, press on it, stand on it nothing
02:48 AM gloops: but steel is 3 times stiffer, and i know how steel bends
02:59 AM gloops: after ongoing pulley slip issues, ive made a careful study of the effects of force on pulleys mounted with grub screws
03:00 AM gloops: in theory the system should work ok, the screw should pin a well fitting pulley to a shaft - with a flat on the shaft
03:01 AM gloops: the problem is the screws ability to hold in the threads
03:02 AM gloops: the screw does not wear through the shaft - which is hardened, the screw does not wear, the screw reverses up the thread
03:04 AM gloops: solution - deeper thread, some kind of self locking thread device - plastic O ring insert
03:06 AM gloops: or damage the screw thread
03:10 AM pink_vampire: gloops: what are you working on?
03:11 AM gloops: pulleys lol
03:12 AM pink_vampire: for what ?
03:12 AM pink_vampire: to the cnc?
03:12 AM IchGucksLive: hi from ice frozen GER
03:12 AM gloops: a router cnc
03:12 AM gloops: yeah
03:12 AM pink_vampire: why?
03:12 AM pink_vampire: go direct drive
03:12 AM gloops: 2 pulleys with chronic slip
03:12 AM Wolf__: because things need to spin
03:12 AM IchGucksLive: gloops: are you sadisfied on the 1350 set
03:12 AM pink_vampire: hi IchGucksLive
03:12 AM gloops: Ichs so far yes, sorry havent had chance to do the tests yet
03:13 AM Wolf__: direct drive doesnt always work
03:13 AM IchGucksLive: gloops: please do
03:13 AM pink_vampire: Wolf__: what do you mean?
03:13 AM gloops: i can go direct which will reduce the tearing force immensely, but the pulleys were to increase speed
03:13 AM IchGucksLive: Wolf_ i always failed to speed on direct Drve
03:13 AM gloops: Ichs ill try but probably later in the week
03:14 AM pink_vampire: gloops: sounds like a wrong design
03:14 AM IchGucksLive: gloops: the CNCshop is the oly i found that provides this sqare 1350
03:14 AM gloops: i made some clamps yesterday and split collars - no good, 6mm bolts tightened to stripping will not hold a 4 inch pulley
03:14 AM pink_vampire: if you need more speed get a ballscrew with multi starts
03:14 AM IchGucksLive: gloops: if you licen to me use 20/25 to get best
03:15 AM gloops: ive got 60-25 tooth on
03:15 AM IchGucksLive: pink_vampire: its also the Torq
03:15 AM IchGucksLive: gloops: not 1,25
03:16 AM gloops: you can turn the screws with 2 fingers, amazing the pulleys wont hold
03:16 AM gloops: screws keep backing out
03:16 AM Wolf__: camming forces + moment of inertia?
03:16 AM Wolf__: or some shit
03:16 AM pink_vampire: it's physics, it will be the same. but with direct drive it will be more ridged
03:16 AM * Wolf__ is just making things up on the fly
03:16 AM IchGucksLive: as i said invest time do fedder
03:17 AM gloops: Wolf yeah + the cicumference of the 60 tooth pulleys magnifies it to the 10mm shaft
03:17 AM Wolf__: direct drive with the same torque would be camming the hub screws out as well
03:17 AM gloops: anyway i wont get it done sat here bbl
03:17 AM IchGucksLive: ok back to work I did need a CAD of a AT5 44Teeth to go on
03:18 AM IchGucksLive: gloops: you can always do better
03:20 AM pink_vampire: gloops: and remember ANY machine have some flex, but as long that your cutting force is very small you are not going to be effected by that too much
03:20 AM Wolf__: switch to a better hub design
03:22 AM pink_vampire: gloops: do you have a real problem with surface finish when you cut? or the machine is completely malfunction because of that?
03:23 AM Laminae: What cnc router machines are is everyone using?
03:23 AM pink_vampire: Laminae: here? metal working milling machine
03:24 AM Laminae: Likea tormach or similar?
03:24 AM pink_vampire: yes
03:24 AM pink_vampire: I have the G0704
03:24 AM Laminae: I've seen a lot conversions on that
03:26 AM pink_vampire: tormach was not exist back then
03:29 AM Wolf__: gloops: http://www.sdp-si.com/products/Fairloc/Index.php
03:31 AM Wolf__: huh, tormach has been around for like 15yrs I think?
03:32 AM pink_vampire: not the 440
03:32 AM Laminae: the 770 is very appealing
03:33 AM pink_vampire: i'm on 2nd floor (old wood house) even the G0704 is a bit too much here
03:34 AM Laminae: If i had a place to put it in this house i might have opted for one of them jut because i'd love to get into machining, realistically i need the plastic panels more than machining but the cool factor of machining is just so high
03:34 AM * Wolf__ kinda wants a laser
03:35 AM Laminae: I laser cut those panels https://imgur.com/a/Zfu2p
03:35 AM pink_vampire: for sheet materials engraver wwill leave dust to the tormach
03:35 AM Laminae: I really don't ever want to laser cut hdpe again
03:36 AM Laminae: It's a massive mess
03:36 AM Wolf__: lol
03:36 AM pink_vampire: what do you mean by that?
03:37 AM Wolf__: molten goo?
03:37 AM Laminae: I have a bunch of .9 nemas and mgn linear rails leftover from printer builds i'd like to make a small bench top engraver for pcb cutting
03:37 AM Laminae: Yeah, lots of melting and rough edges
03:37 AM Wolf__: nice ds1054
03:37 AM Laminae: I cleaned it up a lot befor ei put that together
03:37 AM Wolf__: what watt laser cutter?
03:38 AM Laminae: I don't recall, absurdly over powered for my applications, big kern laser work bought
03:39 AM Laminae: that 1/4 hdpe took five times the time to cut than 1/4in acyrlic
03:39 AM Wolf__: should have done the hdpe then, probably just needed tuned in for the material, did have air assist nozzle right?
03:40 AM pink_vampire: nex time use acrylic
03:40 AM Laminae: Acylic ddoesn't have nearly enough tearout strength
03:40 AM Laminae: Ends up cracking form vibration
03:40 AM Laminae: particularly when printing above 100mms
03:40 AM pink_vampire: what about delrin?
03:41 AM Laminae: that would be a few hundred bucks in delrin
03:41 AM Wolf__: acetal cuts even worse with laser also
03:41 AM pink_vampire: carbon fiber?
03:41 AM Wolf__: even worse
03:41 AM Laminae: If it weren't so hard to source melamine is a very good option
03:42 AM Laminae: That's really what led me to the cnc, because i make a whole lot of stuff out of delrin and hdpe
03:42 AM Laminae: cnc router*
03:42 AM pink_vampire: what size of sheets?
03:43 AM Wolf__: yup. good option, also opens up cutting carbon fiber sheet
03:43 AM Laminae: Depends, the panels on that corexy are 16 x 20
03:44 AM pink_vampire: 16x20"?
03:44 AM Laminae: yeah
03:44 AM pink_vampire: 60x40 is a bit too small
03:45 AM Laminae: For what?
03:45 AM pink_vampire: the x carve have large bed
03:45 AM Laminae: Oh, unfortunately i don't have the space for a machine anywhere near that size
03:46 AM Laminae: That's why i'm using that cbeam machine
03:46 AM Laminae: I'm buying a house next year and it may be a different story then
03:55 AM pink_vampire: Wolf__: what machine is that?
03:56 AM Laminae: That's almost exactly what i'm thinking
03:56 AM Wolf__: crazy design that came out of my head, 2.5w laser using minimal parts, nema 17 steppers, all belt drive and printed parts
03:56 AM Laminae: I'm thinking i'll use a smoothieboard
03:57 AM Laminae: maybe a duet if i'm feeling spendy
03:57 AM Wolf__: and a smoothie x5 board lol
03:57 AM Laminae: .9 or 1.8 steppers?
03:57 AM Wolf__: idk some steppers I got super cheap lol
03:57 AM Wolf__: https://i.imgur.com/HBO8Q3a.jpg
03:58 AM Wolf__: https://i.imgur.com/awiDTkM.jpg
03:58 AM Laminae: Did you reconfigure your limit switches to right side?
03:58 AM Wolf__: no limit, only homing and pray lol
03:59 AM Laminae: I know it's possible to hack octoprint for laser cutting
03:59 AM Laminae: Might be handy if you don't want to be ethered
03:59 AM Laminae: tethered*
03:59 AM pink_vampire: how safe is those 2.5W lasers?
03:59 AM Laminae: man, you could take cheap 50 cent tactiles and it would work!
04:00 AM Laminae: The biggest risk is what you're cutting vamp
04:00 AM Laminae: Things like pvc are very dangerous
04:00 AM Wolf__: I had a spare old laptop so I put linux on it
04:00 AM Wolf__: eye protection needed
04:00 AM Laminae: technically copper is bad because high reflection but if you're wearing laser rated glasses that isn't really a concern
04:00 AM Wolf__: only issue is vapor, fire and reflected laser
04:01 AM pink_vampire: did you try to mark glass with the 2.5W laser?
04:01 AM Wolf__: wavelength on the diode lasers will burn out retinas before you can blink
04:02 AM Wolf__: nope, wont mark glass or clear stuff
04:02 AM Wolf__: need c02 for glass/clear acrylic
04:03 AM Laminae: co2 lasers get insanely expensive
04:03 AM pink_vampire: what about marking powder coat paint?
04:03 AM Laminae: the one that cut those panels is about 150k
04:03 AM Wolf__: that it can do
04:03 AM Laminae: Diode lasers are fantastic for etching tools too
04:03 AM Wolf__: I built that 2.5w as a test bed for the smoothie and software
04:04 AM Laminae: We had one for that but someone broke it and it has been out for rma almost a year
04:04 AM Wolf__: looking at about $4-5k total cost for a 120w RMS C02
04:04 AM Laminae: I would have to build an enclosure because there my girlfriend, cats, dogs
04:05 AM Laminae: i'm not sure that would make it through 1/4in acyrlic though
04:05 AM Laminae: if that's important to you
04:05 AM Wolf__: 120w RMS will do 3/4” plywood
04:05 AM pink_vampire: where do you get the safety glass for the enclosure?
04:06 AM Wolf__: depends on wavelength
04:06 AM Laminae: If you looked at the light table/foam etc i linked earlier i cut all that on the co2
04:06 AM Laminae: the laser safety is a lot easier with co2
04:07 AM pink_vampire: invisible beam.. easy..
04:07 AM Wolf__: 120w co2 I know will do 1/2” acrylic at least, 1/2” ply easy
04:07 AM Laminae: http://www.lasersafetyfacts.com/resources/FAA---visible-laser-hazard-calcs-for-LSF-v02.png
04:07 AM Wolf__: c02 can cut acrylic and mark glass because the wavelength sees those as opaque
04:08 AM Wolf__: so you can make the enclosure out of regular plexiglass
04:08 AM Wolf__: if it starts to melt, you have reflections lol
04:08 AM Laminae: Oops, wrong laser chart
04:09 AM Wolf__: the 2.5w blue laser I have wont even cut cardboard in one pas
04:10 AM pink_vampire: Wolf__: according to the chart it is a fire hazard from 9.3 meters
04:10 AM Laminae: You really need suction and a lot of air pressure to blow out cut
04:11 AM Laminae: Plus bezel clouding
04:11 AM Laminae: Acylic requires you to be attentive, someone started a SERIOUS fire on the Kern a few years ago
04:12 AM Laminae: a co2 laser also degrades if it isn't used
04:12 AM Wolf__: laser kinda implies fire hazard IMO lol
04:13 AM Laminae: What did you pull that lcd out of wolf?
04:13 AM Laminae: and are is it uart or i2c?
04:13 AM Wolf__: https://www.panucatt.com/azteeg_X5_GT_reprap_3d_printer_controller_p/ax5gt.htm
04:14 AM Wolf__: its a Viki2
04:14 AM Laminae: Have you looked at the Duet?
04:15 AM Wolf__: SPI
04:15 AM Wolf__: nope
04:15 AM Wolf__: I haven’t messed with the laser in about a year now
04:15 AM Wolf__: been busy working on heavier metal cutting stuff
04:15 AM Laminae: Oh man, the drivers are tier one, if you're really into high precision https://www.duet3d.com/
04:16 AM pink_vampire: brb
04:18 AM Wolf__: the x5 board I have is loaded with the same TMC2660
04:19 AM Laminae: I missed that, still huge for wifi connectivity, tft touch screen exapnsion, thermistors and sensors, it's a fantastic board
04:19 AM Laminae: I really want 32 bit boards to be more standard
04:19 AM Wolf__: only suck is a few things arent documented about the board, like how to setup the TMC2660 lol
04:19 AM Laminae: 8 bit can be great but there are just so many limitations
04:20 AM Wolf__: 0-10V out doesnt seem to work either
04:20 AM Laminae: Oh yeah, 24v all the way too
04:20 AM Laminae: so tired of 12v boards
04:20 AM Laminae: most serious heat beds and major hot ends need 24v
04:21 AM Wolf__: this one does 35V on the stepper side, 30V main input
04:21 AM Wolf__: has lot of nice things about it
04:22 AM Wolf__: 0-10v out is for VFD control
04:22 AM Laminae: For the cost that is a sweet little board
04:23 AM Wolf__: I need to bug panucatt again to see if I can get the board schematic tho
04:24 AM Laminae: I love all the weird community overlap in cnc
04:24 AM Wolf__: yup lol
04:24 AM Laminae: Bums me out that the maker movement is losing steam
04:24 AM Laminae: Or i guess lost steam really
04:24 AM Wolf__: I have a Re-Arm board somewhere on mu desk here
04:25 AM Wolf__: someday I might swap my 3d printer over to smoothie
04:26 AM Laminae: What is your printer using?
04:26 AM Wolf__: but I’m stuck with the “its not broke so dont fuck with it” right now
04:26 AM Wolf__: modded marlin on ramps board
04:26 AM Laminae: ramps is alright
04:27 AM Wolf__: http://www.panucatt.com/Re_ARM_for_RAMPS_p/ra1768.htm
04:27 AM Wolf__: 32bit ramps =]
04:27 AM Laminae: single extruder?
04:28 AM Wolf__: mine, yeah, I have a i3v 10’x10’x12’
04:28 AM Laminae: Do you tinker with esp32? https://imgur.com/a/rQtpu
04:29 AM Laminae: Been tinkering with them a lot
04:29 AM Wolf__: I totally suck at coding so =\
04:29 AM Laminae: Me too
04:31 AM Wolf__: I need to work on that
04:33 AM Laminae: I learn it best by looking at and editing stuff other people have made
04:33 AM Laminae: changing functions until they break and then fixing them
04:34 AM Wolf__: lol
04:34 AM gloops: btw pink_vampire this isnt a design fault, my design is one of the better ones youll see
04:35 AM Wolf__: yeah that works for simple things, super complex things like multi rotor FC code on the other hand…
04:35 AM XXCoder: you will show everyone eh? ;)
04:36 AM Laminae: For stuff like that i just stare at the libraries until it kind of makes sense
04:36 AM archivist: libraries--
04:36 AM gloops: the problem i have is that m working with pure crap
04:37 AM gloops: the metal used in these parts is dross
04:38 AM Laminae: I like the adafruit libraries, good documentation
04:38 AM Wolf__: yes
04:38 AM Wolf__: helps when things are actually explained lol
05:18 AM Laminae: Hey Wolf, have you done much carbon fiber cutting?
05:26 AM Wolf__: nope
05:41 AM Laminae: That was an option we discussed for cutting an effector for large deltas
05:41 AM Laminae: None of us have tried it though
05:42 AM Laminae: and much more material cost than 6061
05:47 AM XXCoder: hey guys
05:47 AM pink_vampire: hi XXCoder
05:47 AM XXCoder: I need a wireless repeater that I can wire directly to power wires and ethernet connection
05:47 AM XXCoder: so there is no wall wart and such
05:47 AM XXCoder: is there such thing?
05:47 AM XXCoder: hey pink
05:48 AM pink_vampire: try in #hardware
05:48 AM XXCoder: maybe ok
05:50 AM Laminae: I wonder is This Old Tony laughs and if he does what it sounds like
05:51 AM Loetmichel: XXCoder: not very likely
05:52 AM Loetmichel: a repeater uses not that much power, so they usually have external wallwarts
05:52 AM XXCoder: yeah I probably will end up using ceiling box into plugs
05:52 AM Wolf__: XXCoder: http://a.co/5xJk6Gy
05:52 AM XXCoder: actually, plug / ethernet plug (yes, such exists)
05:52 AM XXCoder: then wire connections to it, put repeater near it
05:53 AM Loetmichel: not that many companies would go all the way to ensure CE and other conformity for the PSU if they dont need to because they can buy ready to use certified wallwarts
05:53 AM Wolf__: or do you mean direct wire like electrical hazard type wiring?
05:53 AM Loetmichel: you could use a POE-capable repeater and place the wallawrt at the switch
05:55 AM XXCoder: poe is nice but not worth setup for one item
05:56 AM Wolf__: they make single unit poe injectors
05:56 AM pink_vampire: is just an adapter and normal power supply
05:56 AM Loetmichel: there are some poe-wallwarts with injectors into standard rj45 plugs
05:56 AM XXCoder: nice
05:56 AM XXCoder: just dont connect to wrong one eh ;)
05:58 AM pink_vampire: XXCoder: https://www.dhresource.com/0x0s/f2-albu-g5-M00-6F-5F-rBVaJFkAQyKATF7BAADJogUemiU749.jpg/dhl-black-passive-power-over-ethernet-poe.jpg

06:01 AM Laminae: the big ol gran daddy of hyperlinks there
06:11 AM gloops: right i wont be having any more pulley issues, m8 bolt straight to flat on shaft in 20mm of thread https://ibb.co/e3fzAc
06:11 AM Laminae: Hey wolf, what laser did you use on the diode engraver?
06:11 AM Wolf__: cheapest I could find on aliexpress lol
06:12 AM XXCoder: ubiquiti ap not bad
06:12 AM Laminae: Haha, fair enough
06:16 AM Laminae: I would really like to be able to adjust focal length
06:16 AM XXCoder: arch linked us that cheap but powerful laser diode. but problem is its fiberoptic, and it is "raw cut" so you have to cut and polish ot
06:16 AM XXCoder: or it will spray laser out and probably put your eye out :P
06:17 AM Laminae: How many watts?
06:17 AM XXCoder: something like 30?
06:17 AM XXCoder: hence the danger :)
06:18 AM Laminae: Wow
06:18 AM Laminae: I thought 15watts was risky biscuits
06:20 AM XXCoder: 12w version https://www.ebay.com/itm/ST-Fiber-Optic-Collimator-Focuser-Laser-Diode-Engrave-Etch-Cut-Mark-Illuminate/251597123585
06:21 AM XXCoder: archivist: you there?

06:24 AM Laminae: Once i finish the corexy build and the cnc router build i might feel like doing the laser
06:25 AM XXCoder: or just get one of OpenBuilds ACRO System lol
06:25 AM XXCoder: surpising cheap. lower laser power though.
06:25 AM XXCoder: may be good taste test if want laser lol and can upgrade it
06:25 AM fragalot: please pay more for the glasses than what you paid for the ACRO.
06:26 AM XXCoder: think google is included
06:26 AM XXCoder: *goggles
06:27 AM Laminae: Well i have enough parts left over from printer builds i would mostly just need to buy a controller board and laser
06:27 AM Laminae: have a buncha 350mm mgn rails
06:30 AM jthornton: yikes we are getting an ice storm tonight
06:30 AM jthornton: better test the generator
06:33 AM Laminae: East coast?
06:34 AM jthornton: midwest
06:34 AM Laminae: Ah cool beans
06:35 AM XXCoder: steady 40s/30s here
06:35 AM XXCoder: was 50s f during jan, which is way warm
06:39 AM XXCoder: off to bed I go laters
07:21 AM gloops: i dunno, lasers are becoming pretty common, a lot of diy laser products on ebay
07:22 AM gloops: its 2D, the drawing and stuff is easy, they dont even draw anyway they upload and convet photos stuff like that, or download vectors
07:22 AM archivist: base for an 8x4 router https://www.ebay.co.uk/itm/Granite-surface-table-8-ft-x-4-ft/152895129155
07:23 AM gloops: would do it
07:26 AM gloops: actually something came up with that ive just bid on for 99 pence
07:27 AM gloops: pretty sure he'll remove it if it isnt getting a lot more by the last day
07:27 AM archivist: the 2x2 table :)
07:28 AM gloops: no haha
07:29 AM gloops: hmm, might just finish this second insert, first one doesnt move at all when clamped to shaft and shaft in vice
07:31 AM gloops: nah will have to leave it, might finish tonight
07:34 AM archivist: CMM for the brave https://www.ebay.co.uk/itm/ITP-Coordinate-Measuring-Machine/112799284218

07:44 AM archivist: looks a bit like a key cutting machine
08:05 AM gloops: thats my latest solution to pulley slip, m8 bolt, obviously cut down to size, doesnt slip when yanked in vice https://ibb.co/e3fzAc
08:09 AM gloops: pulley bolted to the larger diameter, reamed to fit stepper, originally made these with ally and wasnt great, plus much smaller screw, its all about the screw threads holding tight
08:15 AM archivist: I made couplings for mk1, using couplers from arc euro trade these days
10:52 AM jthornton: lunch minute was eggciting so back to prepping for the ice storm

01:35 PM gloops: actually not.. https://www.boredpanda.com/carved-wooden-giant-lion-sculpture/
01:36 PM fragalot: :-)
01:39 PM gloops: on the moors not so far from here, there are dozens of old mill wheels abandoned, its the only place you can get millstone grit stone, these are stones a ton or so in weight, very inaccessible places even for a horse and cart sled
01:40 PM Rab: That's an obscene use of that tree. Hopefully it was already dying or something.
01:40 PM gloops: in the old days they reasoned it was better to carve the wheels where the rocks where, then if a fault in the stone was revealed during carving, they hadnt transported it for miles for nothing
01:41 PM gloops: every one abandoned has some fault, pretty sobering to think someone spent weeks chipping away at really hard rock to have just leave it there, and probably not get any money
01:42 PM gloops: http://l7.alamy.com/zooms/ca418b6156134c3e9ed0c7e7535ac3a5/abandoned-millstones-below-stanage-edge-derbyshire-ddg914.jpg
02:23 PM * gloops taps the screen
02:24 PM * fragalot wakes up
02:25 PM gloops: i reckon pink_vampire mummified him/herself with powder coating by accident
02:25 PM fragalot: I think my laptop suffers from buffer under-run for the speakers
02:26 PM fragalot: at random intervals it seems to have a bout of "tin can" sound, and a few seconds later it's fine again
02:26 PM gloops: my speakers havent worked since this install, cant be bothered to fix it
02:27 PM MrHindsight: cheapskate tip: powder coatings are inexpensive sources of powder for SLS printing
02:28 PM gloops: something i really need seems to have fallen down the back of a full triple wardrobe
02:29 PM fragalot: lol
02:29 PM fragalot: MrHindsight: clever.
02:29 PM fragalot: MrHindsight: what material are those coatings anyway?
02:30 PM MrHindsight: they offer polyesters, epoxies and urethanes
02:31 PM MrHindsight: and blends
02:31 PM fragalot: intersting
02:31 PM MrHindsight: they just formulate them to have a Tg >150C, so they melt in an oven, not in your hands
02:31 PM fragalot: hehe
02:32 PM Rab: Nerd NASCAR in T- 14 minutes: https://www.youtube.com/watch?v=wbSwFU6tY1c
02:35 PM MrHindsight: fragalot: any news on that powder printhead?
02:36 PM fragalot: MrHindsight: nothing interesting yet.. just a powder dispenser that can print a pattern
02:38 PM MrHindsight: an inkjet printhead that can handle really high vapor pressure solvents would be much better
02:38 PM fragalot: as an alternative to the laser, or as a method to make the powder stick where you want?
02:38 PM MrHindsight: powder in high vapor pressure vehicle, jet, flash off solvent, laser sinter, repeeat
02:41 PM MrHindsight: ah never mind that would be for room temp depsositon
02:41 PM fragalot: interesting concept, but keeping the nozzles clean would be a challenge
02:43 PM MrHindsight: at elevated temps lots of solvents would do
02:44 PM fragalot: how would you keep the atmosphere inert?
02:44 PM fragalot: (high temp + solvent = ATEX)
02:45 PM MrHindsight: the build chambers are flooded with nitrogen
02:45 PM Wolf__: how about vacuum
02:45 PM MrHindsight: inkjet works with differential pressures
02:45 PM fragalot: MrHindsight: which you continuously contaminate with vapors
02:46 PM MrHindsight: plus lower pressure + lower boiling points
02:46 PM fragalot: granted, there's still no oxygen..
02:46 PM MrHindsight: I said solvent but really meant vehicle
02:46 PM MrHindsight: so depends on your chemistry background
02:48 PM MrHindsight: ink, paint and coatings chemists tend to use the terms a bit differently
02:48 PM fragalot: I have an aqcuired distaste for electrochemistry. :-)
02:48 PM fragalot: normal chemistry is still fine.. the standard rules typically still apply there
02:49 PM MrHindsight: photochemistry is another black magic field
02:50 PM fragalot: I prefer photography. :P
02:50 PM MrHindsight: you just help the reactions with a bit of external electrons or photons
02:50 PM fragalot: MrHindsight: or add one-way polarizing filters rather than ion membranes
02:59 PM phipli: Heh. First car in space
02:59 PM phipli: (other than the various rovers)
03:00 PM MrHindsight: wasn't there a car in space in Flubber?
03:01 PM phipli: the graphics are for this one
03:01 PM MrHindsight: next you're going to say that it was only a movie and made up
03:01 PM phipli: which one?
03:03 PM gregcnc_: did the core land?
03:03 PM phipli: not sure
03:04 PM SpeedEvil: The absence of booster landing footage - or at least the booster standing on the droneship has usually meant that there is a large hole in the droneship.
03:04 PM SpeedEvil: if it misses entirely, the footage continues.
03:04 PM gloops: the sunday sport posted pics of a WW2 bomber on the moon
03:04 PM SpeedEvil: The footage is interrupted by the massive sonic interference to the antenna.
03:04 PM gloops: also this https://farm6.staticflickr.com/5066/5683217529_a69e93613c_z.jpg
03:04 PM phipli: yeah - one of the others I watched they didn't show the explosion
03:05 PM SpeedEvil: They probably don't have prompt (good) footage of the explosion.
03:05 PM xunil: hehe
03:05 PM xunil: i'm hoping the core landing just took out the transmitters
03:05 PM xunil: but was otherwise successful
03:05 PM xunil: still, 2 outta 3 ain't bad
03:06 PM phipli: not exploding is good going for the first launch of a new rocket
03:07 PM xunil: true, though it being made of three falcon 9s gave it a big head start
03:07 PM gregcnc_: same after any trip to taco bell
03:07 PM xunil: haha.
03:09 PM phipli: gregcnc_, do you land?
03:09 PM SpeedEvil: It's a pity in a way it wasn't a side booster they lost if tehy had to lose one - the core is unique.
03:09 PM SpeedEvil: and specially modified quite a lot.
03:10 PM gloops: 1 million pound reward for first amateur rocket in space
03:10 PM phipli: I wonder what the best way to find out if it exploded is?
03:11 PM SpeedEvil: gloops: who?
03:11 PM SpeedEvil: phipli: wait a while till they announce it
03:11 PM gloops: i dont think anyone has claimed it yet?
03:12 PM gloops: nothing though for the first working diy cnc router
03:12 PM SpeedEvil: gloops: I meant who is offering that - I had not heard of any such prize.
03:13 PM gloops: oh, yeah pretty sure the reward exists, it might be more
03:14 PM gloops: hmm nothing comes up on google, i saw it on a TV documentary
03:15 PM SpeedEvil: I think you might be thinking of the x-prize.
03:16 PM SpeedEvil: https://en.wikipedia.org/wiki/N-Prize or perhaps
03:16 PM SpeedEvil: But that's 10K, not $1M
03:17 PM gloops: well, dont take my word for it i may well be wrong, but i watched this thing - they were hoping to get this big prize
03:22 PM gregcnc_: they probably have to get a ship out to the drone ship to see
03:24 PM Tom_itx: first cuts last night
03:24 PM Rab: I'm surprised they don't have drone quadcopters flying around the drone ship, since this is such a continuing problem.
03:24 PM gregcnc_: you would think
03:24 PM Rab: Tom_itx, any video?
03:24 PM Tom_itx: of course
03:25 PM Tom_itx: not the best cutting because i was trying to get the coolant nozzle working right
03:25 PM Tom_itx: and i wasn't sure what kind of aluminum it was
03:25 PM Tom_itx: actually i don't think i published the vid
03:29 PM Tom_itx: https://www.youtube.com/watch?v=jW6RluMbYBQ&feature=youtu.be
03:29 PM Tom_itx: it all gummed up on the first couple parts until i got the coolant goin then it was alot better
03:30 PM gregcnc_: feed looks low, but it could be that 5052 crap
03:30 PM Tom_itx: yeah i'm not sure what it is
03:31 PM Tom_itx: feeds are low because of the spindle hp is also low
03:31 PM Tom_itx: i'll play with it and see where it likes to be best
03:32 PM Tom_itx: near the end i finally got coolant working
03:32 PM gregcnc_: .0005-.001ipt if you want to keep loads low
03:32 PM Tom_itx: i know
03:32 PM Tom_itx: i think i started with .001
03:32 PM gregcnc_: ok there it's cutting
03:32 PM Tom_itx: and wend down a bit
03:33 PM gregcnc_: cool
03:33 PM Tom_itx: a big machine should be able to handle .002-.004 chip load
03:33 PM Tom_itx: on good aluminum
03:33 PM gregcnc_: 1/4" tool?
03:34 PM Tom_itx: 3-16
03:34 PM Tom_itx: i got some 1/4 to try too
03:34 PM Tom_itx: and 3/8
03:35 PM Tom_itx: i stalled the sherline spindle with a 5/16 drill so i didn't wanna push it too much yet
03:35 PM gregcnc_: HP of those sherline spindles?
03:35 PM Tom_itx: not very much
03:35 PM Tom_itx: .6 maybe?
03:35 PM Tom_itx: the spindle is fine it just needs a bigger motor
03:36 PM gregcnc_: I calculate cutting power just because it usually works.. my Emco is only 1HP and can drill 12mm in 6061 fairly quick
03:38 PM Tom_itx: i think i'd have a hard time stalling the steppers though
03:38 PM gregcnc_: yeah those are substantial
03:38 PM Tom_itx: and the amps aren't turned up on them either
03:39 PM Tom_itx: maybe if/when i get a better spindle-motor i will but for now i'll probably leave them where they're at
03:40 PM Tom_itx: my bud offered me an old 6" kurt he has. i may go get it and see if it will fit on there somehow
03:41 PM Tom_itx: been looking at 4" vises
03:41 PM gregcnc_: I have a 4" kurt
03:41 PM Tom_itx: you like it?
03:41 PM Tom_itx: well that goes without saying...
03:41 PM gregcnc_: there are a few 3"
03:41 PM Tom_itx: i think 3 is too small really
03:41 PM gregcnc_: yes, can't complain
03:41 PM gregcnc_: depends on the work you do
03:42 PM Tom_itx: DX40?
03:42 PM gregcnc_: I wish someone made kurt style 2" for the Emco
03:42 PM gregcnc_: PT400
03:42 PM Tom_itx: oh the flat style
03:42 PM gregcnc_: They don't make them anymore, but they are only ground on the sides
03:42 PM Tom_itx: with no boltdown base
03:42 PM Tom_itx: they make similar though
03:42 PM gregcnc_: it's on the table on it's side right now
03:43 PM Tom_itx: i wonder how shars compares to them
03:43 PM Tom_itx: i know they're cheaper
03:44 PM Tom_itx: quality and dollars
03:44 PM gregcnc_: basically from what i read is they are ground to the same tolerances, if you get reall unlucky they crack
03:44 PM gregcnc_: bah they are NOT ground to the same tolerance
03:45 PM Tom_itx: i won't be making aircraft parts with it so i can give a little on tolerance
03:46 PM Tom_itx: i might try running it a little closer to .001 chipload and see if it does better now that the coolant is working
03:47 PM Tom_itx: i can run up to around 5k rpm but usually don't
03:47 PM Deejay: gn8
03:48 PM giacus: hello!
03:48 PM giacus: what's up?
03:48 PM gregcnc_: https://www.kurtworkholding.com/manual-4-inch-versatilelock-vise/3400v
03:48 PM gregcnc_: they flipped the moving jaw to the back
03:49 PM gregcnc_: don't listen to me
03:49 PM gregcnc_: i'mout of it today
03:49 PM gloops: evenin
03:50 PM Tom_itx: for a homebuilt mill made from stuff i got from the junk yard i'm pretty pleased so far
03:50 PM gloops: looks sound Tom
03:50 PM gregcnc_: that's odd, some of the line drawings do show the handle on the stationary jaws side
03:50 PM giacus: hi Jymmm !!!
03:51 PM giacus: you alive?
03:51 PM Tom_itx: gregcnc_ what's the advantage of that style over the one with the boltslots in the base?
03:51 PM Tom_itx: well you know what i mean... i think
03:51 PM gregcnc_: I have mine bolted to the table on it's side right now to hold a part vertically
03:52 PM giacus: Hey! cradek !
03:52 PM Tom_itx: http://allindustrial.com/kurt-d40-machine-vise-anglock-cnc-10-3-16-opening-workholding-iron-clad/?utm_medium=googleshopping&utm_source=bc&matchtype=&network=g&device=c&adposition=1o2&keyword=&campaign={campaign}&adgroup={adgroup}&gclid=CjwKCAiAweXTBRAhEiwAmb3Xu6qZnefOwxfKBYT0TA2uUxg0sVCQ2nAq2gQc-Fg0djrVU76_9M8jaRoCPQQQAvD_BwE
03:52 PM Tom_itx: like that one
03:52 PM Wolf__: thats the reason I got the GMT vise
03:52 PM Tom_itx: just being able to mount it differently?
03:53 PM Tom_itx: i don't think it would fit under my spindle if i did that :)
03:53 PM Tom_itx: limited options here
03:53 PM gregcnc_: It gives a bit tighter spacing if you are putting a bunch of them on a table
03:53 PM Tom_itx: that's true
03:53 PM Tom_itx: for a gang vise setup
03:54 PM Wolf__: err spent more for the GPV because of the flexibility to use it on its side or on end if needed
03:54 PM gregcnc_: https://www.tormach.com//uploads/images/Gallery/products/workholding/Vises_and_Jaws/31759_CNCVise_SideMounted_lrg.jpg.
03:54 PM Tom_itx: i could mount the 6" kurt off to the side of the machine box and use it for squaring blocks etc
03:55 PM Tom_itx: it wouldn't really be in the way there but wouldn't be that useful either
03:55 PM gregcnc_: I was looking for anything at the time I bought this and it has been handy more than once
03:55 PM Tom_itx: there's a fair amount of table i can't really use for anything else
03:56 PM Tom_itx: are those prices about the same as the other style?
03:56 PM Wolf__: IMO just get the shars version
03:57 PM gregcnc_: I would guess more grinding means more cost, 1000USD for the 3400V
03:57 PM Tom_itx: yeah probably so
03:58 PM Wolf__: http://www.shars.com/products/toolholding-workholding/vise/4-single-lock-down-precision-milling-machine-vise
03:58 PM Rab: Tom_itx, 6" Kurt is ~80lbs. Seems like you would want to keep that off the table unless you need it, to save machine wear?
03:58 PM gregcnc_: i paid 400 on ebay for NIB several years ago now
03:59 PM Wolf__: ^ that too, 6” is damn heavy
03:59 PM gregcnc_: I may get a shars for the Arboga. crappy screwless vise is crappy
04:00 PM Tom_itx: i suppose you're right
04:00 PM Tom_itx: i got an old 3" something like that i don't think i've used more than twice
04:00 PM Wolf__: if I wasn’t using a knee mill I wouldnt have bought the 6"
04:00 PM Tom_itx: i could get that out but i really hate to
04:00 PM gregcnc_: unlikely you'll wear your rails in your lifetime on a toy mill
04:01 PM Tom_itx: yeah that's kinda how i look at it
04:01 PM Wolf__: really the bad part is moving it off the table lol
04:01 PM Tom_itx: it's not gonna be runnin 24/7 either like some
04:01 PM giacus: Les watt?
04:02 PM Tom_itx: it can't weigh more than the mill and i put it on my work table
04:02 PM Rab: Those rails look beefy as hell, but the screws are the wear items I had in mind.
04:02 PM Tom_itx: yeah
04:02 PM gregcnc_: you can calculate all that
04:03 PM Wolf__: I may have to get one of the 4” shars vices, make a subplate so the bed and fix jaw will match my 6”
04:03 PM Tom_itx: well i'll eventually get a 4" but the attractive part of the 6" is the cost
04:03 PM Tom_itx: an afternoon of bs'ing with an old friend :D
04:04 PM Wolf__: =) shars 4” $150 isnt terrible
04:04 PM Tom_itx: agreed
04:05 PM Tom_itx: but it isn't blue and doesn't say kurt on it
04:05 PM Wolf__: get both lol
04:05 PM Tom_itx: i can't remember that other good brand we used to use on occasion
04:06 PM gregcnc_: i looked at all of them trying to find a small vise, they are all crazy expensive
04:06 PM gloops: been here before giacus?
04:07 PM Tom_itx: i know
04:07 PM Wolf__: very true gregcnc_
04:07 PM Tom_itx: most of the good 4" are more than the 6
04:07 PM Tom_itx: the 6 is so common
04:07 PM gregcnc_: if you need light weight Chick makes aluminum body
04:07 PM Tom_itx: i think he's got a 10" under his workbench that almost never gets used
04:07 PM Wolf__: I got the GPV-615 because the cost was the same as their 4”
04:08 PM Tom_itx: yeah chick was it..
04:08 PM Tom_itx: some of theirs are nice

04:12 PM phipli: quick release
04:12 PM phipli: ?
04:12 PM Tom_itx: hmm
04:12 PM Tom_itx: those are aluminum?
04:13 PM phipli: I wouldn't have thought so
04:13 PM phipli: but I don't know what it is
04:13 PM Tom_itx: well the ones we had weren't
04:13 PM Tom_itx: but someone here mentioned it

04:13 PM phipli: it is quite pale coloured for steel
04:14 PM Wolf__: looks like a cam lock system
04:14 PM Tom_itx: looks too tall for me too
04:14 PM Wolf__: 100mm bed height
04:15 PM Tom_itx: bed or top of jaw?
04:15 PM Wolf__: bed
04:15 PM Wolf__: 150mm to top of jaw

04:17 PM phipli: anyone know where to get them cheap?
04:17 PM Tom_itx: i'll probably end up with a shars
04:17 PM phipli: even if larger quantities?
04:17 PM Wolf__: check ebay?
04:17 PM Tom_itx: i got a tube of em
04:17 PM Tom_itx: is that cheap enough?
04:18 PM Tom_itx: http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/RTC1st.jpg
04:18 PM MrHindsight: my Shars aren't bad, Pete-from somewhere had poor results from a cheaper model
04:18 PM Tom_itx: mine are like that though
04:19 PM Tom_itx: cheaper model as in different brand?
04:19 PM MrHindsight: cheaper Shars
04:19 PM MrHindsight: said it would push the parts up
04:19 PM Tom_itx: phipli, if that will do i can see if i can find them and send you some
04:19 PM MrHindsight: when cranked down
04:19 PM Tom_itx: yeah
04:19 PM phipli: Tom_itx, wrong continent - postage would be more than the parts :)#
04:20 PM Tom_itx: you think?
04:20 PM phipli: but thank you

04:20 PM Wolf__: does it need to be that style
04:20 PM Tom_itx: i don't know what postage is but i used to send stuff all over for like 3 bux
04:20 PM phipli: Wolf__, that is cheap :)
04:20 PM Wolf__: … would think that stamped steel part would be cheaper lol
04:20 PM phipli: Wolf__, exactly
04:21 PM phipli: Wolf__, looks better too :)
04:21 PM phipli: stupid weird pricing :)
04:21 PM Tom_itx: that looks like the one i've got
04:21 PM phipli: Yeah, I had a few of them but used them at Halloween making "eyes in the dark"

04:23 PM phipli: waiting for the "Dispatched"
04:23 PM Tom_itx: k
04:23 PM phipli: then I only have ~20 days to wait :(
04:23 PM Tom_itx: i generally have parts in hand before i do that :)
04:23 PM gregcnc_: look at tolerance in description
04:23 PM phipli: Tom_itx, no, I have those bits
04:23 PM phipli: this is something else
04:23 PM phipli: I already have some of the part... just figuring I might use more in the near future
04:24 PM MrHindsight: Tom_itx: that looks like the one Pete tried
04:24 PM Tom_itx: yeah i see that now
04:24 PM MrHindsight: http://www.shars.com/products/toolholding-workholding/vise/6-690v-cnc-milling-machine-vise-0-0004-1 are the ones I have
04:25 PM MrHindsight: I used to bend more parts from squeezing them too much than any flatness or height issues
04:27 PM gregcnc_: i cut dies into soft jaws and bend parts on purpose

04:34 PM MrHindsight: you could take a clump of steel and make a vise
04:34 PM phipli: you can also load the software into other things, including a version for the esp8266 if I remember
04:34 PM MrHindsight: it just exude quality when the non machined surfaces have so many voids
04:35 PM MrHindsight: doesn't exude
04:35 PM Tom_itx: you'd think they would pick a good one to take a pic of too
04:36 PM MrHindsight: cost to many monies
04:36 PM Tom_itx: McDonalds shows you what it's supposed to look like, not what's crammed in your torn bag you get
04:36 PM MrHindsight: bags are cheap and full of fiber :)
04:37 PM MrHindsight: not that gunk they put inside them
04:37 PM Tom_itx: yeah they're usually stuck to the cheese too
04:38 PM MrHindsight: I grew up with fast food, not every day but it was always around
04:38 PM Tom_itx: me not so much but once in a while
04:38 PM MrHindsight: I just can't handle it anymore. I now treat it as a laxative.
04:38 PM Tom_itx: works great for that
04:40 PM MrHindsight: found a small cartesian system that TomP gave me in parts
04:40 PM MrHindsight: have to put it together
04:42 PM MrHindsight: was for an EDM
04:42 PM phipli: Tom_itx, is LTO (Link Time Optimisation?) worth playing with when compiling stuff for AVRs?
04:45 PM Tom_itx: i never messed with it
04:46 PM Tom_itx: if you're short on space it might be
04:46 PM Tom_itx: http://tom-itx.no-ip.biz:81/~webpage/avr/

04:48 PM phipli: what was the datalogger?
04:48 PM phipli: (I like making dataloggers - one day I might make a useful one :) )
04:48 PM Tom_itx: some project an aussie and me did a long time ago
04:48 PM Tom_itx: he was making a wind generator
04:48 PM Tom_itx: and wanted to log something
04:49 PM phipli: I made an AVR based 8 channel thermocouple logger by multiplexing the inputs
04:49 PM Tom_itx: i think the blades flew off it in a storm :)
04:49 PM phipli: but I never got to the point of calibrating it
04:50 PM phipli: (the multiplexer would be messing with the very sensitive raw thermocouple signals - I wanted to work out by how much, and how stable it was
04:51 PM Tom_itx: i did find out with that first test cut, my mill goes where you tell it to unlike my sherline
04:52 PM MrHindsight: https://imagebin.ca/v/3qoumb4XZcfM m20-2mm screws
04:52 PM Tom_itx: yours?
04:52 PM phipli: lol - thought you meant M20x2 mm...
04:52 PM phipli: as in 2mm length
04:52 PM phipli: was thinking that was hardly space to get the thread started
04:52 PM MrHindsight: 2mm pitch
04:53 PM phipli: :)
04:53 PM Tom_itx: are those tubes or spring over the screws
04:54 PM gloops: i reckon that big studding bar would work ok
04:54 PM MrHindsight: just a non-threaded section
04:54 PM gregcnc_: Fine acme screws?
04:55 PM MrHindsight: gregcnc_: yes
04:55 PM gloops: a bloke sells pieces on the car boot sale, from his work, the bigger diameter stuff easily looks like it would drive a router or something
04:58 PM MrHindsight: the Y table is in the background
05:05 PM MrHindsight: the XZ must be ~100lbs
05:06 PM MrHindsight: the Y table is a few inches thick with webs
05:07 PM MrHindsight: need a good base to mount it on
05:08 PM MrHindsight: gregcnc_: aren't there some machine bases on the local CL?
05:08 PM gregcnc_: not that i can think of recently
05:09 PM gloops: you bought that MrHindsight?
05:10 PM MrHindsight: enclosures https://chicago.craigslist.org/wcl/tls/d/cnc-mill-and-lathe-enclosures/6474253281.html
05:10 PM MrHindsight: gloops: no, re-found in my stuff
05:10 PM MrHindsight: gift from friend
05:11 PM MrHindsight: comes with the base
05:12 PM MrHindsight: heh $525 OBO or 2 for $1200 :)
05:13 PM MrHindsight: ah fine print "Only the white portion is included. " so no bases :(
05:13 PM gregcnc_: i wonder if they manage to sell any of those and how they got stuck with them
05:13 PM MrHindsight: if I was building a machine that fits it's not a bad deal
05:14 PM MrHindsight: splashproof, windows, doors etc

05:46 PM MrHindsight: how did they expect to get the proper dimensions from just one picture?
05:47 PM MrHindsight: how much work is it to measure your neck, chest, waist and arms?
06:42 PM Tom_itx: then you wash it once and it barely fits your kid let alone you
07:45 PM jopa: Why it is so problematic finding Philips 432 post processor ?
07:45 PM Tom_itx: for what cam?
07:47 PM jopa: Like...any ? I got for Creo I can share with you but can't get any for something like SolidCam, Cimco or CamBam. I don't feel comfortable with Creo.
07:48 PM Tom_itx: so take the one for Creo and make one yourself
07:48 PM jopa: Hm that's viable option. I am software developer mysefl helping in my father workshop. How hard would be to remake Creo to Cimco PP ?
07:49 PM Tom_itx: i've tweaked a few but nothing for current software

07:54 PM skullworks: after all these years my fav 2 1/2D cadcam is the 1990 release of BoBcad v12 for DOS.
07:54 PM Tom_itx: well i still have smartcam for dos
07:55 PM Tom_itx: i don't use that version often but it's still loaded
07:56 PM Tom_itx is now known as Tom_L
07:57 PM skullworks: the BC for Windows jumped the shark like 3X
07:58 PM skullworks: Its on like its 3rd ground up re-write.
07:58 PM Tom_L: i believe that
07:59 PM Tom_L: i looked at it several years ago
08:01 PM skullworks: I'm back using Alibre with the Mecsoft AlibreCAM plug in.
08:02 PM Tom_L: i still use my old copy of smartcam win however my kid is learing the latest mastercam so i've got access to a student copy of that
08:02 PM skullworks: Had SolidWorks from 2004-2009 but when the dark ages fell it wasn't earning its keep and I had to find a cheaper option.
08:03 PM Tom_L: smartcam paid for itself the first year and i've kept it going ever since
08:03 PM Tom_L: i doubt i'll need a different solution for home use now
08:05 PM Tom_L: it won't do 5 axis but i don't care
08:06 PM skullworks: 2004-2006 SolidWorks paid off great - We were designing a prototype system that replaced the outer cover on a Harley twin and had a PTO supuercharger that kinda set back in the gap between the cylinders.
08:08 PM skullworks: Kinda good bad vibes when all your beta testers are about to loose license from speed/ burnout tickets.
08:08 PM skullworks: and buying another half dozen HD bikes just isn't an option.
08:09 PM skullworks: Tom_L given in yet and tried Fusion 360?
08:10 PM Tom_L: no
08:10 PM Tom_L: i doubt i will
08:10 PM malcom2073: I need to try F360 again. I tried it once, but I used solidworks too much, and couldn't get into it
08:10 PM Tom_L: from what i hear it's got a ways to go
08:11 PM Tom_L: it's a good free option for those that can't find anything
08:11 PM Wolf__: need to all bug solid works to come out with a hobby license
08:12 PM skullworks: I'm thinking of trying it - mainly for turning. Adding the turn module to my Mecsoft is like another $1500 and ups the yearly tribute fees.
08:13 PM Tom_L: andy has some addins for lathe for lcnc. have you looked at those?
08:13 PM Tom_L: i have a lathe package and have used it maybe twice
08:14 PM skullworks: I'm not a hobbyist - I am an economically challenged Sole Proprietor.
08:15 PM Tom_L: we did 99% of our lathe stuff MDI
08:15 PM Tom_L: then saved it
08:19 PM skullworks: I need to rebuild our online photo archive - it was partially lost when we switched hosts.
08:20 PM malcom2073: Economically challenged, I like that
08:20 PM malcom2073: Wolf__: Seriously they need to
08:20 PM malcom2073: they have a $100 veterans license
08:21 PM malcom2073: so why not hobbiest?
08:21 PM Wolf__: yeah, would actually be smart for them to do so
08:21 PM malcom2073: Get people using it at home, and they'll recommend it at work
08:21 PM skullworks: I am actually working now - helpdesk conference line - but no one has called in for nearly 2 hours.
08:26 PM skullworks: Parent company that owns SW is Desault - same folks that made Catia.
08:26 PM Tom_L: they put up shop here in town recently
08:27 PM skullworks: I think a big reason why companies avoid low end users is support costs.
08:27 PM malcom2073: Yeah, but tbh, if you make it cheap enough, for the most part the community will support itself
08:27 PM malcom2073: look at the F360 forums
08:28 PM Wolf__: ^ just put it as no phone/live support for hobby/low cost users
08:30 PM skullworks: Company buys a few extra seats of SW and the noobs get sent to a week long training class to get them up to speed. Budget users won't opt for additional cost training but will tie up the supportlines with a bunch of "stupid" questions.
08:32 PM jdh: they make DraftSight also (free)
08:33 PM skullworks: Fusion 360 and OnShape are moving this way - Its semi open source - the user base is the one rapidly tweaking and refining some of the most popular POST configs which frees up company techs to refine internal software bugs.
08:36 PM malcom2073: skullworks: I found SW *very* easy to pick up and learn from scratch though
08:36 PM malcom2073: F360 wasn't as intuitive to me
08:37 PM malcom2073: Onshape is some of the old SW developers isn't it?
08:38 PM skullworks: I had a very rough time with SW - to me it was 100% ass backwards.
08:39 PM Tom_L: it would be nice if they could get the mouse gestures the same in SW and CATIA
08:39 PM Tom_L: more CATIA like would be nice :)
08:39 PM malcom2073: skullworks: Which may be why I find F360 odd, because I started with SW heh
08:40 PM skullworks: Onshape is try #2 from the original lead designer and many of his first crew are back on board. - They think they can do the whole thing a whole lot better - but with bean counters telling them it will cost too much in R&D + testing
08:40 PM Wolf__: I can make stuff in SW, F360 not so much...
08:41 PM skullworks: To me - you decide You need a hole at x/y and it needs to be ## size
08:42 PM skullworks: So the idea of undefined holes floating around on my screen seemed absurd
08:43 PM malcom2073: They don't have to be undefined, but yeah SW gives you the option
08:43 PM malcom2073: Which from what I hear, is odd
08:44 PM skullworks: Think of it from someone moving from an actual drafting table to software.
08:45 PM skullworks: I been doing this too long
08:47 PM skullworks: taking the program I'd written, using a teletype to make a punched paper tape, load into machine and cut air @10% in single block to confirm no tape errors.
08:50 PM skullworks: many of those tape controls could be replaced with an Arduino today.
08:55 PM malcom2073: Heh
08:55 PM malcom2073: yeah well before my time
08:55 PM malcom2073: We did have a punched tape cnc machine though at my last job
08:55 PM malcom2073: We drip-fed it over RS232 though instead
08:55 PM skullworks: Some things in SW didn't seem to make any sense - like the requirement to insert a plane to define the origin of a hole in the side of a cylinder.
08:57 PM skullworks: Think my largest file was 880,000 lines
08:58 PM skullworks: I did the engraving on a tombstone.

09:02 PM skullworks: Blaspher - Gecko drives!
09:02 PM evilroot: I'm going to use the same desk as its base
09:02 PM skullworks: whats the casting on the floor
09:02 PM evilroot: skullworks: what's wrong with Geckodrives?
09:02 PM evilroot: That's the part that links the Y and X axis
09:04 PM skullworks: Make great stepper drives, jus the way you tune and set the G320 it can be off a fair amount of counts, and if your not running glass scales or forked encoder feedback you won't know it.
09:04 PM evilroot: https://drive.google.com/file/d/0B5fQTi1W868OWW1EcWFfVjJGS2c/view?usp=sharing
09:04 PM evilroot: That's the bot together (with covers removed)
09:06 PM skullworks: That ballscrew tells me that baby will really be moving.
09:06 PM evilroot: Well these are G320x . . . I've used them with these machines before and they seem to work quite well
09:06 PM evilroot: Yeah, move speed on them is 1M/sec
09:07 PM evilroot: Also can't beat $100/each for a G320x . . . . these motors are HUGE. 500W at 70VCD for the Y
09:08 PM evilroot: *VDC
09:09 PM skullworks: http://mesanet.com/graphics/adapter/encycolo.png
09:09 PM evilroot: ?
09:10 PM skullworks: Hook these up and you can import the encoder output into LCNC and know exactly where things are.
09:11 PM evilroot: But then I'd still need motor drivers, and a lot more inputs into LCNC
09:11 PM skullworks: its a "Y" output for the encoders - one feed to the gecko, one to the controler
09:11 PM evilroot: Ahh
09:11 PM evilroot: Each motor has three encoder channels
09:11 PM skullworks: and they are fairly cheap
09:11 PM evilroot: A and B at 90deg offset and C is per revolution
09:12 PM evilroot: skullworks: if I end up having issues I'll try that, but so far G320x has worked perfectly
09:12 PM skullworks: Is the "c" labeled as Z or I
09:13 PM evilroot: I forget
09:13 PM skullworks: Is it a robot?
09:14 PM skullworks: like pick n place
09:23 PM evilroot: Multipurpose robot
09:23 PM evilroot: Seiko D-Tran XM5000
09:24 PM evilroot: Pick and place was one application, also used for all sorts of manufacturing, assembly, and biotech stuff
09:24 PM evilroot: I'm going to mount a 1.5kw spindle and use it to mill aluminum
09:25 PM evilroot: This particular one has a 600x400x250mm work area
09:25 PM MrHindsight: http://universalurethane.com/Urethane_Products/Polyurethane_Urethane_Rods_Specifications.html#specs anyone have a lower priced source for urethane rod stock?
09:38 PM MrHindsight: evilroot: are you going to support the other side of the X arm or leave it cantilevered like that?
09:50 PM evilroot: Leave it as it is. The frame is more than rigid enough to handle the load.
09:52 PM evilroot: The Y axis base is milled from 4" thick solid aluminum and the rails are THK SR-25W
09:53 PM evilroot: That way I can carve pieces larger than the effective work area if I want
09:56 PM evilroot: Though I probably won't, I'll be using this machine to mill aluminum parts for 3d printers
10:21 PM pink_vampire: hi
10:36 PM jesseg: hi
10:38 PM pink_vampire: hi jesseg
10:52 PM jesseg: How's it going there pink_vampire
10:52 PM pink_vampire: just workink on too many things
10:52 PM jesseg: same her
10:52 PM jesseg: here
10:53 PM pink_vampire: i need to reduce the diameter of the valve shaft
11:31 PM Wolf__: lathe…
11:31 PM pink_vampire: i need one..
11:31 PM evilroot: Machine shop
11:31 PM Wolf__: cutting tool in mill vise, work in collet)
11:32 PM pink_vampire: also need one
11:32 PM pink_vampire: i wish i had a collet fot that
11:33 PM pink_vampire: it is almost fit in 3/16" but it is 0.2mm larger
11:33 PM Wolf__: er collet holder and full set of collets is a must own IMO
11:34 PM pink_vampire: the shaft it 4.87, the reduced size need to be 3.93
11:34 PM Wolf__: my er-32 set and er-32 tool holders come in handy
11:37 PM Wolf__: er-32 collets set in 1/32 steps covers any size needed due to the range they close down to
11:41 PM evilroot: I'm using an Er11 on my current build
11:42 PM evilroot: But it will just be cutting aluminum
11:42 PM Wolf__: I have a couple er-15 holders, and a couple er-32 holders
11:42 PM Wolf__: my mini lathe has a er-32 chuck as well
11:43 PM Wolf__: https://i.imgur.com/8TEjtQb.jpg
11:52 PM pink_vampire: i don't have one
11:53 PM pink_vampire: and the shaft have thread on it
11:53 PM Wolf__: I shortened a M4 setscrew in a ER-32 collet last night so threads dont matter
11:56 PM pink_vampire: anyway I don't have a lathe / ER collets
11:56 PM Wolf__: part of what makes collets so great
11:57 PM pink_vampire: this is how I solved it https://i.imgur.com/Z7b2KU3.jpg
11:58 PM Wolf__: take rod stock same size as tool holder, drill/tap hole matching shaft to turn, thread it in to stub that is in tool holder, use cutter of some sort in vise to turn shaft down
