12:21 AM veegee: The machine screws included with my panel have a triangular shank
12:26 AM veegee: Instead of a perfectly round shank, you can clearly see it has 3 flat sides that the thread is on, with rounded corners
12:26 AM veegee: Why do they do that?
12:26 AM veegee: It it supposed to help with self tapping?
12:26 AM XXCoder: pics?
12:26 AM veegee: Ok taking them now
12:26 AM veegee: I'll take it with my 90mm macro prime
12:30 AM perry_j1987: tomorrows going to be fun day
12:30 AM perry_j1987: going to .... tram the 6040
12:31 AM perry_j1987: go over the thing make sure its all still together nicely
12:35 AM veegee: XXCoder https://www.youtube.com/watch?v=DuwMAOuLwcc&feature=youtu.be
12:35 AM veegee: Watch the shank, it's clearly three sided instead of round
12:36 AM XXCoder: yeah wow weird
12:36 AM XXCoder: i bet its whats that word again
12:36 AM XXCoder: ah yes!
12:36 AM XXCoder: constant width
12:36 AM veegee: I don't get it
12:37 AM XXCoder: welcome to weird world lemme link it
12:37 AM XXCoder: https://youtu.be/fRqwYsfiME8
12:38 AM XXCoder: other type, one nearer yours https://youtu.be/2eUWT9cI23o
12:38 AM XXCoder: but 2d cross section
12:40 AM XXCoder: once I get a working 3d printer im making few of those constant widtj spheres.
12:41 AM veegee: Ok but what's the point?
12:41 AM XXCoder: for screws? dunno
12:41 AM XXCoder: maybe youre right, its for self tapping, more space for chips
12:42 AM veegee: Yeah that's the only reason I can think of. Some of the holes in the sheet metal weren't tapped
12:43 AM XXCoder: more constant widthj fun https://youtu.be/fOojOfpcPZM
12:47 AM W1N9Zr0: https://superuser.com/questions/516513/why-the-different-coarse-threaded-screws/516550#516550 suggests they're for thread-forming in sheet metal
12:48 AM XXCoder: check out one of pictures. 2d constant width!
01:23 AM XXCoder: ohh new HALON but safer. https://interestingengineering.com/new-carbon-fiber-material-dissolves-in-water-flame-retardant
01:50 AM enleth: any hints on chucking rimmed timing pulleys in a lathe? the best idea I've had so far is to chuck a short piece of aluminum round stock scrap in a 3-jaw, machine a recess that tightly fits the pulley, drill and tap a hole or three in the side walls for set screws bearing on the teeth and use CA glue and those set screws to mount the pulley
01:51 AM enleth: the point here is to machine the pulley's inside bore
01:54 AM jymmmm: XXCoder: Nitrogen to replace halon
02:01 AM XXCoder: isnt that most of air already :P
02:12 AM Deejay: moin
02:50 AM enleth: XXCoder: uh, that's totally not what this article is about
02:51 AM enleth: XXCoder: it's about halogen-based resin additives that were traditionally used to make fiber-resin composites flame-retardant
02:53 AM enleth: granted, their mode of operation is similar to how halon fire suppression works (i.e. they make the burning plastic locally generate a halon-like fire suppressant as it burns, so it stops), but I don't think anyone in the industry would consider the terms interchangeable
02:54 AM enleth: halon-based suppression systems are there to stay for now in some specific industries, it's hard to replace them with anything because they stop the oxidation process chemically instead of just pushing oxygen out like nitrogen flooding would
02:57 AM XXCoder: it does menion fire supressing
05:14 AM JT-Cave: morning
05:15 AM XXCoder: yo
05:19 AM pink_vampire: https://i.imgur.com/ZVB4bEO.png
05:19 AM XXCoder: ah thats your crack grinder eh'
05:19 AM XXCoder: ;)
05:19 AM XXCoder: thats pretty damn small
05:19 AM XXCoder: or is that novelity huge aa battery? ;)
05:20 AM pink_vampire: you almost got it right...
05:24 AM XXCoder: cocoine?
05:28 AM pink_vampire: https://i.imgur.com/lF4WegA.png
05:28 AM XXCoder: sd killer?
05:29 AM pink_vampire: why not?
05:29 AM XXCoder: yeah
05:56 AM andypugh: enleth: to machine pulleys I tend to machine a split ring to “fill in” the groove and grip that in the three-jaw.
05:58 AM andypugh: So, bore a hole the pulley OD in a bit of stock bigger then the flange OD, part it off, cut it in half, plonk it round the pulley.
06:21 AM howto: i am not able to compile smictrl on wheezy
06:25 AM howto: guys the laptop has a smi enabled chipset but when i run s 0 on it it ends with a register unchanged message.What do i do to disable it?
06:25 AM howto: on ubuntu atleast i can run the thing
06:27 AM andypugh: howto: You are reading the wrong docs, I think
06:28 AM andypugh: There is absolutely no need to compile smictrl yourself.
06:28 AM howto: how do i do this on wheezy?
06:29 AM andypugh: You just need to edit rtai.conf: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?FixingSMIIssues
06:29 AM howto: beacause the i compiled on ubuntu ends up with some syntax error thing
06:30 AM howto: page not found sir
06:30 AM andypugh: Huh?
06:30 AM howto: when i click on readme smi link inside the site it leads me to that error
06:31 AM JT-Cave: link works for me
06:31 AM howto: when i click readme.smi link\
06:31 AM XXCoder: security problem with readme.mi
06:31 AM andypugh: So just don’t read it :-)
06:31 AM XXCoder: invalid certification for site
06:34 AM howto: i paased that point andy but the link is dead on my part
06:35 AM howto: itd says 'page not found' when i bypass security
06:35 AM andypugh: Why do you need to read that link?
06:35 AM andypugh: If you _really_ want to read that readme file, it is here: http://svn.savannah.gnu.org/viewvc/rtai/vulcano/base/arch/x86/calibration/README.SMI?view=markup
06:35 AM howto: beacause i am not a linux expert
06:36 AM andypugh: But, why?
06:36 AM andypugh: If you are not a Linux expert then you _really_ don’t need to read thet READEM
06:37 AM andypugh: All you need to do with Wheezy is step 4 on http://wiki.linuxcnc.org/cgi-bin/wiki.pl?FixingSMIIssues
06:37 AM howto: i can not read thogts andy...how should i suppose to know what was at that link i had to see to know ...does that make any sesnse to you?
06:38 AM howto: now i know
06:38 AM howto: and yeah dont need it :)
06:38 AM howto: is there an allready compiled smictrl for wheezy in its repositories?
06:39 AM andypugh: Are you using RTAI?
06:39 AM andypugh: Have you tried using rtai_smi ?
06:39 AM howto: yep
06:39 AM howto: how do i use that?
06:40 AM andypugh: You do what step 4 of the Wiki page tells you to do. You add it to the load line of rtai.conf
06:41 AM andypugh: sudo nano /etc/linuxcnc/rtapi.conf
06:41 AM andypugh: copy, paste, copy, paste
06:41 AM andypugh: Ctrl-X Y
06:41 AM andypugh: run linuxcnc
06:44 AM Tom_L: morning
06:45 AM JT-Cave: morning
06:45 AM JT-Cave: going to try and finish up those logs this morning
06:47 AM Tom_L: better get it done before the cloud moves over
06:47 AM Tom_L: it's due here this weekend sometime
06:49 AM JT-Cave: yea I know
06:49 AM JT-Cave: it's already hot out there
06:49 AM Tom_L: it's not 'hot' but kinda muggy here
06:50 AM Tom_L: 77 currently
06:51 AM Tom_L: https://www.kake.com/story/42297431/kdhe-issues-warning-for-expected-dust-storm
06:52 AM Tom_L: looks like the south might be getting the worst of it
07:08 AM JT-Cave: yea looks like it will be south of me today
07:31 AM JT-Cave: well it looks like Raspberry Pi OS Lite with OpenBox works as expected with PyQt5... finally
08:04 AM skunkworks: JT-Cave: so you could run probe basic
08:04 AM skunkworks: ?
08:08 AM veek: do you guys buy parts through a company account or through a personal account when dealing with big retailers
08:38 AM veegee: veek I make it in the name of my company
08:38 AM veegee: but I just bill it on my personal card
08:38 AM jymmmm: Tom_L: You get a dust storm and flood warnings, lovely... Get your video camera ready, sounds like it'll look like shit (mud) hit the fan :D
08:39 AM veegee: Do they make 600V load centers/circuit breaker panels?
08:41 AM jymmmm: veegee: Google says... hahaha
08:41 AM veegee: Yeah it didn't give me any good results
08:41 AM veegee: my industrial unit just has a common bus
08:41 AM jymmmm: https://www.platt.com/search.aspx?q=3+phase+125+amp+3R+Sub+panel+600v
08:42 AM veegee: I looked through them, it ignores the very important 600V part
08:43 AM veegee: Also, a transformer is rated at 30kVA 600 delta to 240 delta, does that mean it's 30kVA total or 30kVA per phase?
08:43 AM jymmmm: https://electricalpowerandcontrol.com/product/square-d-3-phase-225a-600v-series-e1-i-line-panel-new/
08:43 AM jymmmm: I have no clue
08:47 AM veegee: Yeah it's 30kVA total. so 30,000/sqrt(3)/240 is the phase current
09:35 AM Tom_L: JT-Cave, python2 or python3?
09:37 AM perry_j1987: morning
09:40 AM perry_j1987: i wonder "how" flat granite tiles are
09:41 AM SpeedEvil: I suspect polished ones may be fairly flat.
09:42 AM jymmmm: perry_j1987: Top yea, bottom not so much
09:42 AM perry_j1987: im going to "TRAM THE CNC" today (starburst effect and swoosh)
09:43 AM Tom_L: perry_j1987, shine a laser beam across em and you'll see
09:43 AM perry_j1987: dont think i own any laser beams
09:44 AM SpeedEvil: grazing angle reflections tell you a fair amount
09:44 AM Tom_L: or a piece of mirror
09:44 AM SpeedEvil: Look at the reflection of (say) fine text off the surface at 1 degree to the surface.
09:44 AM Tom_L: it is likely a higher quality than pane glass
09:45 AM perry_j1987: that is true
09:45 AM Tom_L: and should be 'flat' on both sides
09:45 AM SpeedEvil: Well, float glass can be pretty decent TBH
09:45 AM perry_j1987: i have a glass tile here i could nab for the day
09:46 AM SpeedEvil: Also, you can take several tiles and get them pretty smooth and flat without much issue
09:46 AM SpeedEvil: Just abrasively lapping
09:48 AM Tom_L: mmm, radar looks relatively clear. must be the dust coming because it looks cloudy
10:06 AM perry_j1987: hmm https://amzn.to/2CDYNvd if you used one of these as a perm mounted touch plate and then tie the switch itself into e-stop to handle accidents so if it tries ramming the endmill in to far and doesnt register the probe (using just the body of the switch)
10:21 AM tiwake: when anodizing two different colors with two different bases (water based and solvent base), should the solvent go down first, or the water?
10:46 AM perry_j1987: quiet in here today
11:10 AM perry_j1987: what all methods are there for checking z axis perpendicularity
11:24 AM Tom_L: perry_j1987, i used an indicator in the spindle
11:24 AM perry_j1987: i dont have a 123 block or anything to sweep
11:25 AM Tom_L: https://www.youtube.com/watch?v=GtFTRyS__Yc
11:27 AM pink_vampire: poor indicator
11:27 AM perry_j1987: hes got too much angle on that stylus doesnt he?
11:29 AM pink_vampire: make the tip a bit more flat, and use tip with larger radius is you can, or put it in angle, so it will be easier on the indicator
11:29 AM perry_j1987: that doesnt check for perpendicularity
11:29 AM Tom_L: sure it does
11:29 AM Tom_L: explain why it doesn't
11:30 AM perry_j1987: you have to move the z up and down against a square
11:30 AM Tom_L: are you not cutting with the spindle?
11:30 AM Tom_L: doesn't the spindle need to be perp to the plate?
11:31 AM Tom_L: i do know what you mean and i did check that too but not on yt
11:31 AM Tom_L: indicator on a height gage would work
11:31 AM Tom_L: just fasten it to the table
11:31 AM Tom_L: in both planes
11:31 AM perry_j1987: im trying to figure out the sequence of events to check from start to finish on this 6040
11:32 AM Tom_L: now go buy a $500 height gage...
11:32 AM perry_j1987: need to head over to harbor freight and pick up a set of feeler gauges to cut up for shims
11:34 AM perry_j1987: from what i was reading they were saying that you need to sweep the z up and down first and get it 90 to the x/y and then tram the head
11:34 AM perry_j1987: so your not cutting ramps ie z moving in x or y on z moves
11:35 AM pink_vampire: perry_j1987: to run the Z against square can fool you because you don't know if your Z is right or you have a table that is not flat. or the square can bi in slight angle
11:36 AM perry_j1987: this whole thing makes my head hurt lol
11:36 AM pink_vampire: perry_j1987: the way Tom_L did it, is the correct way. to make sure the spindle is square with the table
11:36 AM perry_j1987: this 6040 is a wet noodle
11:37 AM perry_j1987: ya but the spindle can be square to the table but the z going up and down it could still be angled?
11:37 AM pink_vampire: every is rubber in those high precision measurements
11:39 AM perry_j1987: imagine it traveling like a funicular
11:40 AM pink_vampire: it can but if you don't know if it square with the table, you can't eliminate where the error is coming from
11:47 AM perry_j1987: k ima head over to harbor freight and get some feeler gauges to use as shim stock
11:58 AM skunkworks: come on - just use your coordinate measuring mill... http://electronicsam.com/images/greenmachine/20180831_162711.jpg
12:14 PM perry_j1987: lol
12:14 PM perry_j1987: looks big enough.. can i bring my 6040 over to sit up there? :P
12:18 PM skunkworks: :) 6040? one wrong move and it would be turned inside out ;)
12:27 PM perry_j1987: lol
12:28 PM perry_j1987: just waiting for fusion to finish adding offline cache
12:28 PM perry_j1987: tired of using phone teathering out in the shop heh
12:30 PM Tom_L: skunkworks, :)
12:31 PM Tom_L: perry_j1987, you adjust it until it's right then you do it 2 more times
12:33 PM perry_j1987: aye
12:34 PM perry_j1987: ok offline cache finished
12:34 PM perry_j1987: 3 gigs worth of cad models lol
12:34 PM perry_j1987: heading out to get some shim stock
12:34 PM perry_j1987: cya later
12:36 PM Tom_L: does a 6040 even have enough z travel to worry if it's perpendicular?
12:57 PM veek: oh the shame - you utter rotter sync - that price was for 40 rolls - there's a tiny arrow on the french website https://www.antalis.fr/eshop/packaging-machines-emballage/protection-anti-corrosion/film-barriere/complexe-alu-vacupac
01:00 PM veek: oh! how could i have missed that *bitter sobs*
01:01 PM pink_vampire: Tom_L: exactly, I think the 6040 have only 3-4" of Z travel.
01:06 PM roycroft: pink_vampire: rumor has it that you use linuxcnc to control your 3d printer
01:06 PM roycroft: is this correct?
01:06 PM pink_vampire: my mill was my first printer
01:06 PM pink_vampire: and yes, it was with linuxcnc
01:06 PM roycroft: yes, i recall your talking about that the other day
01:07 PM roycroft: but your dedicated 3d printer doesn't use linuxcnc?
01:08 PM roycroft: i'm asking because the printer i recently bought is working great, but, as 3d printers tend to be, it's really slow
01:08 PM roycroft: and i'm finding more and more uses for it
01:08 PM roycroft: so i'm already thinking about getting another one, and am pondering building the second one from scratch
01:27 PM pink_vampire: roycroft: my 3d printer run marlin and octopi
01:29 PM roycroft: that's what i'm using too
01:29 PM pink_vampire: if it's work don't fix it.
01:29 PM roycroft: i'm not considering converting my current one
01:30 PM roycroft: but if i build one from scratch i can use anything
01:30 PM roycroft: i may just buy another ender 5
01:30 PM pink_vampire: what do you have now?
01:30 PM roycroft: an ender 5
01:31 PM pink_vampire: I have just simple clear acrylic,
01:31 PM roycroft: they make an version of that printer with a larger print volume, but i've not made anything even remotely approaching the limits of this one yet
01:31 PM roycroft: the print volume is 220x220x300
01:31 PM roycroft: which is pretty big
01:32 PM pink_vampire: yeah, mine is 180x180x180
01:32 PM roycroft: that's big enough for most things
01:33 PM pink_vampire: for larger parts, I ask the mill to make something from metal.
01:36 PM roycroft: the printer is so useful i can't believe i didn't get one a long time ago
01:36 PM roycroft: i went out to the shop this morning, for example, and needed to use my spindle sander
01:37 PM roycroft: it has an odd size dust collection port, and whenever i use it i have to do some funky stuff with hose clamps and duct tape to attach it to an extractor
01:37 PM pink_vampire: yeah I know it is the best tool ever!
01:37 PM roycroft: this morning i just measured it, and the extractor hose, and the adapter is almost done printing
01:37 PM roycroft: it took like 5 minutes to design it in solidworks
01:37 PM pink_vampire: vase mode?
01:38 PM roycroft: two slightly tapered cylinders with a tapered transition
01:38 PM pink_vampire: what slicer are you using?
01:38 PM roycroft: and if by vase mode you mean i sketched the profile and did a rotational extrusion, yes
01:38 PM roycroft: i'm using cura
01:39 PM pink_vampire: same as me
01:39 PM pink_vampire: I want to try recycle HDPE and try printing it.
01:44 PM roycroft: https://www.roycroft.us/Vacuum-Port-Adapter.pdf
01:45 PM Tom_L: it's a reducer
01:45 PM Tom_L: pvc isn't the right size?
01:46 PM roycroft: no, not at all
01:46 PM roycroft: the spindle sander has an odd size dust port
01:46 PM roycroft: the extractor hose is for a festool extractor, which is 32mm
01:46 PM roycroft: pretty standard in europe, but not here
01:47 PM roycroft: i could buy something and modify it in the lathe
01:47 PM roycroft: but it seemed easier to just measure the ports and print it
01:48 PM roycroft: even if the first part doesn't quite fit
01:48 PM roycroft: it will take seconds to modify the drawing
01:48 PM roycroft: a couple hours to reprint, but that's just clicking the "print" button and walking away until the email arrives saying it's done
02:42 PM Tom_L: when were we discussing air tanks? i'd just fixed the drain on mine. went out to check and it's still at full pressure just like i left it back then
02:42 PM Tom_L: no leaks test... pass
02:50 PM roycroft: about 3-4 days ago
02:51 PM jymmmm: Tom_L: Now to run the 'will it stop a 50cal' test
02:52 PM jymmmm: Tom_L: If that test passes, then run the "Hold my beer..." test
03:13 PM Loetmichel: *MAAAAN* why me? I just were on the way back from a friend in my convertible... about 20km from home: ((!)) lights up and the brake pedal gets mushy... got a liter of dot4 at the next fuel station, refilled the reservoir, crawled home... parked, pumped the pedal a few times: reservoir empty again. and a big puddle under the left rear wheel. *GREAT*... so i tried if the Station wagon will
03:13 PM Loetmichel: work for commuting monday: nope, nothing. not even unlocking the car. After manaully unlocking it with the key a carwled into the back (luckily the rear seats were already folded) and connected a jumper box. Tried to start it: clack... lights out. Jumper box also empty. Had to connect TWO 12V 40Ah AGM blocks in parallel that i had by chance in the car to get it startet... drove 20 minutes
03:13 PM Loetmichel: to recharge the batteries a bit... now i have to see where i can get new brake lines installed on the convertible in a hurry. :-(
03:22 PM Tom_L: diy
03:23 PM Loetmichel: not today
03:23 PM Tom_L: those use a double flare on the end right?
03:23 PM Tom_L: haven't had to do one of those in quite a while
03:23 PM Loetmichel: have to see if i can remove the rear wheel tomorrow when its not so dark, and then look if i can find the broken part
03:24 PM Loetmichel: i suspect the flex line between read left caliper and hard line
03:24 PM Loetmichel: because i have dot4 spray on the inside of the rubber but NOT in the rim
03:24 PM Tom_L: alot easier fix
03:24 PM Loetmichel: but i cant say for sure until i remove the wheel
03:25 PM Loetmichel: and now its to dark
03:25 PM Tom_L: just hope the connection isn't rusted beyond use
03:27 PM Tom_L: if the line is bad, the piston pucks probably are too
03:28 PM Tom_L: i couldn't count how many drum brake cylinders i've honed and rebuilt...
03:29 PM Tom_L: fewer disk since they're newer
03:32 PM perry_j1987: o/
03:32 PM miss0r2: Goodevening
03:33 PM perry_j1987: just got out to the shop
03:33 PM perry_j1987: got feeler gauges to cut up for shim stock
03:33 PM perry_j1987: and plethora of other things
03:34 PM Loetmichel: Tom_L: its a 2004 BMW 318i convertible... no brake drums anywhere in sight ;)
03:34 PM perry_j1987: just for initial thing i threw an indicator on the front face of my spindle and swept the z up and down
03:34 PM miss0r2: uh oh
03:34 PM perry_j1987: .17 off in however long this 6040's z travel is
03:34 PM Loetmichel: (apart from the handbrake, but thats INSIDE the rear discs and cable driven
03:34 PM Tom_L: Loetmichel, maybe you'll be lucky then and the pistons & o rings are still good
03:35 PM Tom_L: perry_j1987, .17" ?
03:35 PM miss0r2: perry_j1987: I assume you are talking mm? :D
03:35 PM perry_j1987: ya
03:36 PM miss0r2: which is still horrible.. but not *that* horrible :D
03:36 PM Loetmichel: Tom_L: as rapid as that pedal got mushy and disappeared i would take a bet that the rubber flex line exploded that feeds the caliper from the rigid line. the car doesent look AS rusted from the underside that it would warrant a steel line being rusted thru
03:36 PM Tom_L: if it's off .17" in z i'd question who put it together...
03:36 PM perry_j1987: china put it together
03:36 PM Loetmichel: Tom_L: some chinaman ;)
03:36 PM perry_j1987: so it being off .17" would still be in their wheel house haha
03:36 PM Tom_L: how much z travel?
03:37 PM Loetmichel: about 80mm
03:37 PM miss0r2: I had one of those generic chinesium routers (fleabay special) in the past. Much the same experience
03:37 PM Loetmichel: depending on where the spindle is mounted
03:37 PM miss0r2: mine was off alot in the x-y squareness
03:38 PM Tom_L: i feel much better now knowing i didn't get one
03:38 PM Tom_L: i could eyeball it closer than that
03:39 PM perry_j1987: i got the spindle in the mount at base of spindle
03:40 PM miss0r2: issues I encountered with mine(include but is not limited to) that the round linear guides for the X-axis was not installed in any bores or recesses - they were simply pulled up against a painted surface with a M6 screw...
03:40 PM miss0r2: through a 8mm hole if I recall correctly.
03:40 PM miss0r2: It left some adjustment possibilities :D
03:40 PM perry_j1987: wait hah
03:40 PM perry_j1987: i had too much angle on the stylus
03:41 PM perry_j1987: just adjusted that so it was measuring right
03:41 PM perry_j1987: .12 now
03:41 PM Tom_L: inch or mm?
03:41 PM perry_j1987: now its a precision cnc :P
03:41 PM perry_j1987: mm
03:41 PM Tom_L: ok that's not quite as bad
03:41 PM perry_j1987: welp guess im done for the day now
03:41 PM perry_j1987: crack a beer
03:41 PM perry_j1987: lol
03:41 PM Tom_L: no you gotta get it trammed!!!!!
03:41 PM miss0r2: hahaha
03:42 PM perry_j1987: darn it being held accountable lol
03:42 PM perry_j1987: ok i suppose
03:42 PM Tom_L: gawd that was easy...
03:42 PM miss0r2: meh depends.. If it is only ever used for engraving or cutting out 0.5mm sheet that out-of-tram-ness is alright :D
03:42 PM perry_j1987: i gotta rig up a way to get an indicator in the collet next eh?
03:43 PM Tom_L: yup
03:43 PM Tom_L: yeah the edges won't be any more bevelled than a waterjet
03:44 PM perry_j1987: i dont have a way to put my plunge style in the collet
03:44 PM perry_j1987: whats this other style called with the lever stylus
03:46 PM miss0r2: what you just called
03:46 PM miss0r2: a lever indicator
03:47 PM miss0r2: But if you can measure that it is out of tram moving the spindle up and down, your imprecission is between the linear rails of your Z axis and your spindle
03:48 PM miss0r2: i.e. the spindle is mounted at an angle to the Z-axis rails
03:50 PM * miss0r2 is drawing some new parts to mount the solar array on the land rover camper project
03:52 PM * Loetmichel is thinking about ordering a couple 50W W panels to mount on the Station wagon. As long as the convertible is working the wagon just sits in the parking spot.
03:52 PM perry_j1987: i love my solar
03:52 PM Loetmichel: its NOT good for the batteries to get discharged to less than 2 V ;)
03:52 PM miss0r2: Loetmichel: haha 2 volts. I plan on stopping a smidge before I reach that level :D
03:53 PM miss0r2: I'm installing two 12v/100ah AGM batteries
03:53 PM Loetmichel: miss0r2: i meant the car starter batteries
03:53 PM miss0r2: I have 240watts of "flex" monocrystal solar panels on the roof. and a cute 40 amp MPPT charger. This thing will be adequate for running my beer fridge :D
03:53 PM Loetmichel: BMWs are chronical standby current suckers ;)
03:54 PM Loetmichel: when it sits for more than 2 months its apparently down to less than 2V :-)
03:55 PM miss0r2: hehe. This setup of mine has a two-way VSR so that the generator can charge both the starter battery and then the solar battery once the starter battery is full. and the solar panels can.. you get the idea.
03:56 PM miss0r2: also, I have battery isolators on everything. Both my old land rovers have one. I disconnect the battery when i park. Because reasons
03:56 PM perry_j1987: https://ibb.co/SrHR9CW
03:56 PM perry_j1987: got mounted in there
03:56 PM perry_j1987: just unscrewed from magbase and put in a junk collet
03:56 PM miss0r2: Indeed. Do yourself a favour and measure across two parallels
03:57 PM perry_j1987: not bad idea
03:57 PM miss0r2: also, triple check the measurements, as those ajustable arms have a tendency to wander
03:59 PM perry_j1987: got it zero'd in 6 oclock position
03:59 PM perry_j1987: checking 12 now
03:59 PM perry_j1987: nm cant see back there heh going to zero in 12 and check 6 instead haha
04:00 PM miss0r2: hehe
04:00 PM miss0r2: Get yourself a mirror like the rest of us!
04:01 PM perry_j1987: that'd be another trip to the store heh
04:03 PM Loetmichel: miss0r2: 2001 BMW 525i... if you isolate the battery when parking it WILL complain at next start. (aka have a ton of "faults" storend in the ECU and run in limp mode for a while)
04:03 PM miss0r2: pffft... "ECU"... :)
04:04 PM miss0r2: The most complicated electronics in my land rovers are the indicator relays
04:04 PM Loetmichel: hihi, i can imagine. and still it is famously unreliable ;)
04:05 PM perry_j1987: appears -.28 from back to front
04:05 PM miss0r2: Atleast it doesn't drain the battery or alternately gives you ECU faults that results in a limp drive! HA! This is always a limp drive, so jokes on you! :D
04:05 PM miss0r2: perry_j1987: That is noticeable :D
04:06 PM Loetmichel: perry_j1987: one of the reasons mine have both a vacuum table on them that i can face off
04:06 PM perry_j1987: thats a roughly 180mm circle i got
04:07 PM miss0r2: considering it is a generic chinesium machine I would argue that is will within factory specs.. :]
04:07 PM perry_j1987: lol
04:07 PM miss0r2: but a reasonable result should be around 0.02mm on such a machine
04:08 PM perry_j1987: this one has a fully milled spindle/bearing mount
04:08 PM miss0r2: yeah.. who milled it?
04:08 PM perry_j1987: so only place to adjust tram for in front to back direction (y) is with the bolts that hold it to the x rails
04:09 PM miss0r2: no!
04:09 PM miss0r2: That won't fix your error.
04:09 PM miss0r2: you need to ajust this error between the z-axis rail carriages and the spindle mount
04:09 PM perry_j1987: that joint does not exist
04:10 PM perry_j1987: the z axis rails and motor mount are 1 solid block
04:10 PM miss0r2: okay. I need to make sure I understand how you did the first measurement. Can you describe the setup for me?
04:11 PM perry_j1987: uploading pic one min
04:12 PM perry_j1987: https://ibb.co/6RhddcG
04:13 PM miss0r2: That looks like a smaller version of the last picture you posted?
04:13 PM perry_j1987: first one showed the indicator arm this is up showing the mount
04:14 PM miss0r2: I get your latest setup. But the first setup you did, where you deduced that it moved 0.12mm, where exactly did you have the indicator stand mounted, and what were you measuring on?
04:15 PM perry_j1987: oh i just had it stuck on the vise with magbase and was sweeping the front face of the spindle body
04:15 PM miss0r2: damn
04:15 PM perry_j1987: not an extremly accurate place to measure from
04:15 PM miss0r2: well.. this means one of two things:
04:16 PM miss0r2: 1) The spindle body is tapered or
04:16 PM miss0r2: 2) the spindle is mounted at an angle to the z-axis rails i.e. that massive block is faulty
04:16 PM perry_j1987: the z axis is held onto x with a plate on top and bottom
04:17 PM miss0r2: it it was perfectly parallel to the z-axis rails you would not get any needle movement doing that first test(assuming the spindle housing is nice and straight).
04:17 PM perry_j1987: so if one of those plates was loosened and tapped it could adjust the z in that orientation
04:17 PM miss0r2: it could still be out of tram, even if the needle did not move during the first test.
04:18 PM miss0r2: if that milled out block is not completely straight, you will never be able to get this machine trammed properly.
04:18 PM perry_j1987: china wouldnt have sold me something... not perfect you know
04:19 PM miss0r2: :D
04:19 PM miss0r2: A thought occured:
04:19 PM miss0r2: if you remove the spindle and indicate inside the spindle bore
04:19 PM perry_j1987: aye i could do that
04:19 PM miss0r2: sweeping z-axis up and down
04:19 PM miss0r2: then you could determin if the spindle is crooked in the bore or the bore if off
04:21 PM perry_j1987: there's so much flex in this
04:21 PM perry_j1987: i can push on spindle with finger and indicator spins lal the way off the scales lol
04:22 PM miss0r2: yeah. I'm not surprised. You can look at that later :D Try to figure out if it is flex or if theres some loose screws
04:26 PM roycroft: or just don't push on the spindle :)
04:27 PM roycroft: if we stop pushing on the spindle the flex will go away
04:27 PM roycroft: does that sound famliar?
04:27 PM miss0r2: word of the wise :D
04:27 PM Deejay: gn8
04:29 PM roycroft: i got lucky - my dust collector port adapter that i printed this morning fits like a glove on both sides
04:30 PM roycroft: no more wanky duct tape tricks for that :)
04:30 PM roycroft: wonky, rather
04:39 PM pink_vampire: roycroft: the part look nice!
04:39 PM pink_vampire: it is still printing it?
04:39 PM XXCoder: roy pics? heh
04:40 PM andypugh: perry_j1987: Maybe find a different image hosting site? That one shows me your pic very small, and naked ladies somewhat bigger.
04:40 PM perry_j1987: naked ladies?
04:41 PM perry_j1987: i told them to get out of the shot while i was taking the pic
04:41 PM andypugh: Yes. (well, three lingerie models and one allegedly live cam)
04:43 PM pink_vampire: perry_j1987: this is what I got https://i.imgur.com/elesCo5.png
04:43 PM andypugh: Maybe you have an ad-blocker?
04:45 PM pink_vampire: or 3
04:45 PM XXCoder: https://i.ibb.co/TLJmF3p/6-F785-D94-FBC3-406-A-BC3-E-1-E80-DD6-A3-ED1.jpg more direct lionk to perry's link
04:45 PM XXCoder: i love noscript
04:46 PM roycroft: it's done
04:46 PM roycroft: and as i said, it fits like a glove
04:46 PM andypugh: Yeah, for humour value, a screenshot uploaded to the same site: https://ibb.co/DbFnKtR
04:47 PM roycroft: the side on the sander is a slip fit, but there's an o-ring grove on the sander, so i'll be able to seal that part up nicely
04:47 PM pink_vampire: perry_j1987: I'm not an expert on that, but I think there is gravitational problems at your location, your machine seams to be mounted on the wall?
04:47 PM roycroft: the extractor side is a slight interference fit, but the extractor hose is rubber, and i printed it with a 0.5 degree draft, so it's nice and snug
04:48 PM roycroft: i'll probably toss it in the lathe so i can smooth the inside a bit
04:48 PM XXCoder: andypugh: might want to label it nfsw since some in here might be at work. (not me I dont chat on irc at work)
04:49 PM pink_vampire: roycroft: drum sander!
04:49 PM roycroft: *sigh*
04:49 PM roycroft: i was hoping the drum sander would be finished last night
04:49 PM Tom_L: roycroft, OJ's glove didn't fit very well...
04:49 PM roycroft: but when i went to mount the motor, the new stand interfered with the motor caps, so i had to do a bit of remodeling today
04:49 PM pink_vampire: what material did you use for the print?
04:49 PM andypugh: My point was that the original link was NSFW.
04:49 PM Tom_L: i stopped using that analogy after that :)
04:50 PM roycroft: petg
04:50 PM roycroft: i'm not happy with petg generally, but i have the better part of a spool of it
04:50 PM roycroft: so i'm using it up on things where it doesn't matter that much
04:50 PM roycroft: tom_l: if the fit is crap you must not extract!
04:51 PM pink_vampire: you need to sand it very lightly, and keep it cold!
04:51 PM XXCoder: andy yeah should always say so at same line as link :) i didnt see your comments earlier, others might do same. (note i dont care about it being nfsw but others at work might)
04:51 PM roycroft: yeah, i'll probably spin it at about 150rpm and use a really light touch
04:52 PM roycroft: i just want to get rid of places for sawdust to collect
04:52 PM roycroft: i'm 100% concerned about functionality, and 0% concerned about appearance
04:52 PM XXCoder: interesting. just had idea of self-wetting drum sander
04:52 PM roycroft: nice
04:52 PM roycroft: my state is at 1.8 cases per 100,000
04:52 PM roycroft: 45th out of 50 states
04:53 PM XXCoder: would been bin below it of course to hold water and pump up again
04:53 PM roycroft: in spite of our curve flattening, but not going down
04:53 PM XXCoder: roycroft: wa went from #1 to #23rd not bad
04:53 PM pink_vampire: I'm thinking about my next "big" tool and I'm not sure if to go with a laser cutter, or something like a router cnc. and I don;t like the 5W-10W diodes, I want to be able to cut stuff.
04:53 PM XXCoder: pink you can easily make one yourself for fairly cheap lol
04:54 PM Tom_L: 40W co2?
04:54 PM XXCoder: (diode anyway)
04:54 PM jymmmm: 240W CO2
04:54 PM Tom_L: star wars!
04:54 PM pink_vampire: 2435340W CO2
04:54 PM jymmmm: Well, 140-180W
04:54 PM Tom_L: you can't even count that high!
04:55 PM jymmmm: pink_vampire: At that then jsut go 50W YaG and you cna engrave titanium
04:55 PM pink_vampire: I'm trying to cut stuff not fusing atom using laser
04:55 PM roycroft: we have a bunch of, um, stumpycranials here, mostly in eastern and southern oregon, who have mistaken common sense health precautions with politics, and are not behaving well
04:56 PM roycroft: and we also have a lot of teenage girls who seem to have decided that looking cute is more important than accidently kiling people
04:56 PM Tom_L: sounds like Ga
04:56 PM XXCoder: fun
04:56 PM roycroft: as a result, we've had a couple recent spikes
04:56 PM roycroft: but we're still 45th in spite of that
04:56 PM jymmmm: pink_vampire: Done with a 40W Yag https://i.imgur.com/sqcqBG2.jpg
04:56 PM XXCoder: that looks nice
04:57 PM pink_vampire: VERY COOL!
04:57 PM jymmmm: titanium ring
04:57 PM roycroft: anyway, i have a shed to finish residing
04:57 PM pink_vampire: jymmmm: thank you for making my even more confused!
04:57 PM XXCoder: not that I would ever wear ring. if I ever get married I would accept it for coupel hours then remove it again for good
04:57 PM roycroft: i should get back to that - the weather is perfect for it today
04:57 PM roycroft: 20ish and slightly overcast
04:57 PM jymmmm: pink_vampire: Fiber YaG FTW
04:58 PM Tom_L: jymmmm, you gettin any hint of dust storm over there?
04:58 PM jymmmm: Tom_L: None, but I'm at 2500ft
04:59 PM pink_vampire: XXCoder: you can tattoo the ring, and I'm sure jymmmm will be happy to laser engrave something if you will decide to remove it
04:59 PM XXCoder: lol nah its just token
05:00 PM jymmmm: pink_vampire: Actually, you could look into surplus medical fiber lasers
05:01 PM pink_vampire: let me see. I see that I have only 2 eyes, and replacement parts are not readily available yet
05:02 PM jymmmm: <rim shot>
05:03 PM XXCoder: lol
05:03 PM XXCoder: if you buy cheap one, get NOT cheap goggles rated at blocking your laser machine nm
05:04 PM jymmmm: XXCoder: 1/8 plexi is enough to block harmful radiation on my 30W CO2 laser
05:05 PM XXCoder: well yeah like pink said...
05:08 PM pink_vampire: still no one made shaper origin alternative
05:12 PM jymmmm: Tis sad that I have to use hot glue to repair my propane heater
05:13 PM pink_vampire: tis?
05:13 PM jymmmm: It's
05:13 PM pink_vampire: who?
05:14 PM pink_vampire: what? "hot glue to repair my propane heater"???
05:14 PM jymmmm: Yeah
05:14 PM pink_vampire: who sad that?
05:14 PM andypugh: ’Tis is a perfectly valid (and Shakesperean) abbreviation for “It is"
05:16 PM * jymmmm did see Midnight summer drema in a park play once
05:16 PM jymmmm: it was pretty good
05:49 PM perry_j1987: which mill was it you had pink_vampire
05:49 PM perry_j1987: a grizzly one right?
05:49 PM pink_vampire: yeah, G0704
05:50 PM perry_j1987: would you pick that one again
05:50 PM pink_vampire: yes
05:50 PM pink_vampire: 100%
05:51 PM perry_j1987: they have so many options
05:51 PM perry_j1987: why not the others?
05:52 PM pink_vampire: very long X axis, very cheap to start, you have A lot of kits now to convert it to a CNC,
05:52 PM perry_j1987: did you get the stand or no
05:53 PM pink_vampire: yes, it was a kit
05:53 PM pink_vampire: mill + stand
05:53 PM pink_vampire: I also got super over kill servos for it, (4 not 3)
05:55 PM perry_j1987: how much were they
05:56 PM _unreal_: sup how you guys doing? hanging with a friend of miihne at universal studios
05:57 PM pink_vampire: perry_j1987: https://www.automationtechnologiesinc.com/products-page/servo-nema34-kits/4-axis-nema34/
05:59 PM perry_j1987: sheesh lol
05:59 PM perry_j1987: what are you cuttin :P
06:00 PM pink_vampire: anything
06:01 PM pink_vampire: but I know alot of people get the 850OZ steppers and it work fine
06:04 PM pink_vampire: and now you have the option to print temporary mounts for the motors, and then to cut the conversion parts on your machine
06:07 PM perry_j1987: that would be a fun progression
06:09 PM perry_j1987: 850 are you talking about those geared nema23s?
06:11 PM pink_vampire: total cost of my machine include everything (machine, conversion kit, servos, aux 60K spindle, elctrical cabinet, tools..) still cheaper then the tormach 440, and I have faster machine with more travel that can do 4+1 cnc and rigid tapping.
06:12 PM andypugh: Why do they use oz.in? Oh, I know, because it makes the numbers bigger than lb.ft
06:12 PM perry_j1987: 60k spindle? thought you want slower for metal ?
06:13 PM pink_vampire: everything.
06:57 PM Tom_L: andypugh, it sounds more impressive that way
07:12 PM veegee: Hmmm, this looks like a decent price I think: https://www.aircompressorsdirect.com/FS-Curtis-DA-240E/p14571.html
07:12 PM veegee: For a regenerative desiccant dryer
07:21 PM gregcnc: Are you painting?
08:00 PM veegee: gregcnc no but from an idealistic perspective... it's just nice to have very dry air
08:01 PM veegee: I mean yeah I will be painting from time to time, but it's not the main use of the compressor
08:01 PM veegee: It looks like the desiccant dryers aren't that much more expensive than refrigerated air dryers, so why even bother with refrigerated?
11:14 PM jymmmm: FINALLY got the heater fixed and put back together, but literally have to use bailing wire to hold it together
