01:29 AM pink_vampire: HI ALL
03:11 AM pink_vampire: ?
03:11 AM pink_vampire: someone here?
03:11 AM fdarling: yes
03:12 AM pink_vampire: cool
03:12 AM fdarling: do you need help with something?
03:12 AM fdarling: (I can't guarantee I can help, but I can try and tell you if I definitely can't!)
03:14 AM pink_vampire: i just got a 3d printer!
03:14 AM fdarling: pink_vampire: I personally own around 7 3D printers, plus my relative owns a couple of the more expensive ones, and we have a couple at my workplace
03:14 AM fdarling: pink_vampire: so if you need help with that I am definitely your guy ;-)
03:16 AM pink_vampire: i got a used 3d printer
03:16 AM fdarling: pink_vampire: most of them run Marlin on Arduino Mega 2560 (or similar) microcontrollers, but some of them use ARM chips, like Duet and Smoothieboard
03:16 AM fdarling: pink_vampire: all of my 3D printers are used, it's cheaper that way and I can fix them up
03:17 AM * sensille just built one
03:17 AM fdarling: pink_vampire: my current workhorse printer is an Ultimaker 3, but that being said you can get even a low end Prusa i3 clone to print amazingly if you get a decent hot end and are willing to print slowly and upgrade some parts on it
03:17 AM pink_vampire: i think it is clone of the reprap prusa i3
03:17 AM Deejay: moin
03:18 AM pink_vampire: the guy that sold me the printer upgrade the hotend
03:18 AM fdarling: my relative bought (on my behalf) a used Stratasys uPrint Plus, it is a low end of the "commercial" 3D printers. I am hoping to hack on it is why I bought it, I am not a fan of the prices they charge for their official filament...
03:18 AM fdarling: pink_vampire: an official E3D v6 is only like $65, so it doesn't have to break the bank
03:19 AM fdarling: pink_vampire: the "print cores" for the Ultimaker 3 are more like $250 which is crazy, but they do have a good system for quick changing the hot-end
03:19 AM fdarling: I have access to a machine shop, so I often machine my own parts
03:21 AM pink_vampire: my machine shop is 2' from the printer
03:22 AM pink_vampire: i leveled the bed
03:22 AM pink_vampire: and i'm trying now to print something from the sd card
03:23 AM fdarling: pink_vampire: my advice to you is, backup the firmware and upgrade to the latest version of Marlin
03:23 AM fdarling: pink_vampire: (I assume it's a printer that runs Marlin)
03:23 AM fdarling: pink_vampire: a lot of printers ship with ancient firmware
03:24 AM pink_vampire: do you know what causes delamination ?
03:24 AM fdarling: pink_vampire: if you have access to an AVR programmer you can jack into the printer's board and backup the current firmware on it. You'll want to backup both the flash and the EEPROM to be able to 100% restore it to how you got it
03:24 AM fdarling: pink_vampire: delamination? as in your print comes off the bed?
03:25 AM fdarling: pink_vampire: it depends on what material you are working with and what your bed is made out of, but there are a few main factors:
03:25 AM fdarling: 1) getting the layer to stick in the first place with two sub-categories:
03:26 AM fdarling: 1a) Having something the material can stick to, be it painter's tape, hairspray, Kapton, PEI, or any number of marketed build plate surfaces such as "Buildtak", PrintBite, etc.
03:26 AM pink_vampire: i mean the bond between each layer is not very good
03:26 AM Wolf__: step one, what bed surface, heated?, what filament type
03:26 AM fdarling: 1b) making sure that said material doesn't have oil on it, usually from people's hands ;-)
03:26 AM pink_vampire: yes, glass heated bed
03:27 AM pink_vampire: it is pla
03:27 AM fdarling: pink_vampire: if the bond between layers isn't good, it can be because of printing at too low of a temperature (it's hot enough to melt, but not hot enough to melt the previous layer as well thereby "welding" the layers together
03:27 AM fdarling: pink_vampire: but in some cases I've actually seen filament soooooo bad that it's intra-layer adhesion is hopeless
03:27 AM Wolf__: ok, nozzle size, layer height, and did you calibrate the hotend feed to proper step/mm
03:28 AM fdarling: pink_vampire: so sometimes you simply need to try another color or brand of filament
03:28 AM fdarling: pink_vampire: my go-to filament is eSun PLA+ on Amazon, about $23/kg. You can get filament as cheap as $11/kg but your mileage may vary
03:28 AM Wolf__: atomic filaments here
03:28 AM fdarling: pink_vampire: Wolf__ is right, you do need to do a lot of calibrating before worrying about the results
03:29 AM fdarling: pink_vampire: you need to make sure it's extruding the correct amount of mm through the hot end, you do this by taking the nozzle completely off and having it feed filament through and simply measuring how much is fed
03:29 AM pink_vampire: "matter hackers 1.75mm"
03:29 AM pink_vampire: the nozzle is 0.4mm
03:29 AM Wolf__: http://zennmaster.com/makingstuff/reprap-101-calibrating-your-extruder-part-1-e-steps
03:30 AM fdarling: pink_vampire: for example, you feed some out of the hotend, sharpie mark it as high up as you can reach into the hotend with the pen, then feed 100mm and mark it the same way again, feed more out, cut it off, and measure the distance between the marks
03:30 AM fdarling: pink_vampire: it must be very close to the theoretical 100mm, if not you must adjust your steps per mm for the extruder to compensate
03:30 AM pink_vampire: https://i.imgur.com/JfGDQ7k.png
03:30 AM Wolf__: thats one of the best step by step guides I know of for dialing in a printer
03:31 AM fdarling: pink_vampire: you also need to make sure X/Y steps per mm are accurate, but that's usually much more straightforward, being only dependant on timing belt teeth count and belt pitch and stepper motor degrees per step * microstepping multiplier
03:32 AM Wolf__: pls should be point and shoot once everything is setup, layer delam might then be hot end temp too low/high
03:32 AM fdarling: I usually print a calibration cube with 1 perimeter, no ceiling, and 0% infill (hollow) to see the wall thickness. I calibrate that then work on other stuff
03:32 AM pink_vampire: how the print look? https://i.imgur.com/JfGDQ7k.png
03:32 AM Wolf__: I hate myself so I use ABS all the time lol
03:32 AM fdarling: some things are interdependent, like if you have the X/Y factors off it will "compress" the extrusion to be fatter or skinner than it should be
03:33 AM fdarling: you can tell though if the X/Y is off because it will be a scalar
03:33 AM Wolf__: and clear pla is the worst for sharing pics of prints lol
03:33 AM pink_vampire: it is silver
03:33 AM fdarling: like 20mm cube will be off by 0.2mm (1%) and a 40mm cube will be off by 0.4mm (1% still). If it's the extrusion width that is the issue, it will be a constant offset
03:33 AM fdarling: 20mm cube could be 0.2mm off (1%) and 40mm cube would be 0.2mm off (0.5%)
03:34 AM fdarling: is any of this making sense?
03:34 AM pink_vampire: yes
03:34 AM pink_vampire: i level the bed with my dial test indicator not with a paper
03:35 AM Wolf__: silver pla https://i.imgur.com/0yldgdW.jpg
03:35 AM Wolf__: and my bed is warped lol
03:35 AM Wolf__: has been for 4 yrs
03:36 AM Wolf__: https://i.imgur.com/rZeYTyK.jpg
03:36 AM pink_vampire: the weller thing is also 3d printed?
03:36 AM pink_vampire: look amazing!
03:37 AM Wolf__: no weller is my WMD1 soldering station
03:38 AM pink_vampire: WMD1!!
03:38 AM Wolf__: https://i.imgur.com/IkDCyhS.jpg 3d print in PETG
03:39 AM pink_vampire: the black part look amazing the dial O_O
03:39 AM Wolf__: came out ugly, 3 tries and that was the best, trying to paint it was a mess
03:41 AM pink_vampire: Wolf__: you have a cnc milling machine
03:41 AM Wolf__: someday I’ll bother to re-calibrate the printer, its off
03:41 AM pink_vampire: stop using plastic on machines!
03:41 AM Wolf__: I use the hell out of the 3d printer for non-critical parts
03:42 AM fdarling: 3D printers do well for making handles, little brackets and holders, etc
03:42 AM Wolf__: stuff with weird hollow parts
03:43 AM Wolf__: gears https://i.imgur.com/d6eqnNG.jpg lol
03:43 AM fdarling: don't tell me that is driving your lathe...
03:43 AM Wolf__: they are lol
03:45 AM pink_vampire: what happen to you Wolf__ O_o
03:46 AM pink_vampire: https://i.imgur.com/VONd3S0.png
03:46 AM Wolf__: my 3d printer makes better parts then my x1 cnc
03:46 AM pink_vampire: how this thing work?
03:46 AM Wolf__: idk, I save as STL in SW
03:47 AM pink_vampire: https://i.imgur.com/gik0AxI.png WTF
03:47 AM Wolf__: I also made a test cube in SW with x/y/z matching the work space so I know which side is up/down on the bed coming out of cad lol
03:48 AM fdarling: in SolidWorks you must have your plane by the "Front" if you want X/Y to be the sketch and Z the extruded portion
03:48 AM fdarling: that always throws me off... I would think that would be the "Top" view
03:48 AM Wolf__: yup
03:49 AM pink_vampire: what slicer is recommended?
03:49 AM Wolf__: I got tired of flipping parts lol
03:49 AM Wolf__: idk I use slicer
03:50 AM Wolf__: slic3r? not even sure, I haven’t messed with any of the core stuff on my printer in 2 yrs
03:51 AM fdarling: I used slic3r for a long time, then used Simplify 3D (which is all the rage, it's definitely good), but now-days I use Cura which does a pretty good job too
03:52 AM fdarling: on rare occasions I've had slic3r out-do Simplify 3D, but usually Simplify 3D's support material is the best
03:52 AM fdarling: Cura is pretty good usually though, and it's user interface is nice
03:52 AM fdarling: I would love to write my own slicer, but I'd need some help from some Israelis... I'd want to use CGAL as the core algorithm library
03:54 AM pink_vampire: why from Israelis?
03:54 AM fdarling: because it's mainly developed by these guys in Tel Aviv
03:55 AM fdarling: the learning curve for using it is really high, mostly because it's C++ template based and if you have one typo the whole thing pukes at you
03:56 AM pink_vampire: what software is developed by them?
03:57 AM fdarling: https://doc.cgal.org/latest/Straight_skeleton_2/index.html
03:57 AM fdarling: CGAL can process 2D and 3D goemetry and do things like offsetting the contours for doing cutting passes in routing/milling
03:57 AM fdarling: or for doing perimeters in 3D printing...
03:58 AM fdarling: the algorithms that they use are much more bulletproof than what the standard slicer uses
03:58 AM pink_vampire: no idea
03:58 AM fdarling: their library is optimized for flexibility and speed, not necessarily for pretty error messages when you create a syntax error
04:00 AM pink_vampire: I'm not a programmer
04:00 AM pink_vampire: i love metal chips
04:00 AM pink_vampire: https://i.imgur.com/X4doK00.png
04:01 AM pink_vampire: what is the problem here?
04:01 AM * sensille was expecting large metal chips
04:02 AM pink_vampire: sensille: with the HF spindle there is no such a thing large chips, it become dust
04:02 AM fdarling: pink_vampire: it looks to me like you were printing way too hot
04:03 AM fdarling: pink_vampire: towards the bottom left it also looks like the chair leg might have shifted over, which is odd considering the rest of it seems fine
04:03 AM fdarling: (in that way)
04:03 AM pink_vampire: https://i.imgur.com/gYbmssr.png
04:03 AM fdarling: pink_vampire: you might also be overextruding a lot, which would explain the spaghetti plastic everywhere
04:04 AM pink_vampire: this is how i print stuff at the past
05:26 AM jthornton: morning
05:26 AM XXCoder: hey jt
05:35 AM Tom_L: morning
06:20 AM jthornton: going to be a real nice day here sunny and 66°F
06:23 AM XXCoder: 53f and rain. typical spring
07:15 AM Loetmichel: oh maaan. Customer sends 2 dell/wyse thin clients to us for repair. so we did... but he set an admin password we dont know and arent able to get from him. so no testing/no sending back the units without test... WHEN do the customer learn to reset them beforehand to default? now we have to go to dell and go thru the lenghly process of getting them to reset the units with challenge7response
07:15 AM Loetmichel: codes and stuff. pretty irritating and expensive for the customer, it wasnt a warranty case... :-(
07:50 AM Elmo40: pink_vampire, too fast. the extrusion isn't catching up to your movements.
07:51 AM Elmo40: pink_vampire, is it TPU?
10:57 AM pink_vampire: Elmo40: the pink prints are few years old
11:21 AM Wolf__: darkness
11:22 AM Wolf__: grr wrong window lol
11:35 AM jymmm: Loetmichel: Honestly, not your fault or problem. You could hack it, but then they might complain about that too
12:07 PM jymmm: Has anyone worked on a way to dispense granules (like powder laundry soap) by weight ???
12:08 PM Loetmichel: jymmm: not hacking. just a lengthly process with dell (challenge-response codes, but you have to get the right person that has the code generator on the phone)
12:10 PM Loetmichel: and boss WILL bill the customer for the 2-3 hours it takes to unlock the device. we have to (EMI-)measure it in working condition before sending it back, so we have no choice but to reset it. what i dont understand is: this customer has sent a bunch of those clients to us for repairs before. and we always say it has to be "factory reset" before we can repair it because of said process with
12:10 PM Loetmichel: dell.
12:10 PM Loetmichel: and EVERY time they send it password-locked.
12:10 PM Loetmichel: and EVERY time they get billed.
12:10 PM Loetmichel: and we are NOT cheap
12:10 PM Loetmichel: WHY???
12:12 PM jymmm: Loetmichel: They don't care and/or just don't have a clue. You've done your due diligence
12:13 PM Loetmichel: still annoying to get thru that process with dell. the right guy with the code generator is quite difficult to get to.
12:14 PM jymmm: Get his phone/email and keep that handy?
12:15 PM Loetmichel: i know his phone and email
12:16 PM Loetmichel: i even know two service guys who have the code gen
12:16 PM Loetmichel: but they are doing other things as well and not always reachable
12:16 PM Loetmichel: usually it takes an hour or to to get to them
12:16 PM jymmm: Loetmichel: and you can't just zap the bios/cmos?
12:18 PM Loetmichel: nope. its in a special code chip
12:18 PM Loetmichel: you cant even flash a new bios
12:18 PM pink_vampire: https://i.imgur.com/XYD4wbL.png
12:18 PM Loetmichel: "security"
12:18 PM Loetmichel: pink_vampire: that looks fairly "transparent"
12:19 PM jymmm: Loetmichel: TPU bs???
12:19 PM pink_vampire: Loetmichel: i love it
12:19 PM Loetmichel: jymmm: more like those crypto-chipcards
12:19 PM Loetmichel: but integrated into the motherboard
12:20 PM jymmm: Loetmichel: Yeah, that sounds like TPU alright =)
12:20 PM Loetmichel: nope
12:20 PM Loetmichel: its not even an Intel processor
12:20 PM Loetmichel: "teradici something"
12:20 PM Loetmichel: thin/zero client
12:20 PM Loetmichel: ah, sorry
12:21 PM jymmm: ah, rebranded ones
12:21 PM Loetmichel: mistook TPU for Trusted Platform Module
12:21 PM Loetmichel: no, the processor is from teradici
12:21 PM jymmm: Loetmichel: Well, yeah, the non intel equiv of TPU
12:21 PM Loetmichel: IIRC an ARM with some stream decoding hardware
12:22 PM jymmm: Loetmichel: Oh, it's probably just dvd encoding, want the master key? lmao
12:22 PM Loetmichel: i dont think so
12:23 PM Loetmichel: you know what remote desktop/VMware Horizon is?
12:23 PM Loetmichel: thats what its for
12:23 PM jymmm: Loetmichel: Sadly, sometimes they don't even bother to change what they get off-the-shelf.
12:23 PM Loetmichel: it has no harddrive or something
12:23 PM jymmm: Loetmichel: Yeah, I understood when you said thin client
12:23 PM Loetmichel: its just a small cpu and some ram and a display driver and a network interfeace that can connect remotely to a PC
12:24 PM Loetmichel: ok
12:25 PM Loetmichel: as far as i understand it the teradici processor is made especially to support thin client protocols
12:25 PM Loetmichel: and can decode the "usual" streams in hardware
12:25 PM Loetmichel: so the arm that is in there is pretty low power.
12:25 PM Loetmichel: both in computing power and in electrical power used
12:25 PM jymmm: Loetmichel: Yeah, probably a ASCI or FPGA dedicated for the task
12:25 PM Loetmichel: the whole thing runs off a 12V 3A PSU ;)
12:26 PM jymmm: Loetmichel: When it runs from 300ma, let me know =)
12:26 PM pink_vampire: jymmm: https://i.imgur.com/0VpvBMT.png
12:26 PM Loetmichel: (ok, we mount 12V 5A PSUs because we power the 24" displays that we built in there from that PSU, too
12:26 PM Loetmichel: )
12:27 PM jymmm: pink_vampire: you NORMAL length freak ;)
12:27 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=14412&g2_imageViewsIndex=1
12:27 PM Loetmichel: thats such a client (the silver box is the "VMware esxi test server", not the cpu :-)
12:28 PM jymmm: pink_vampire: do you do your own nails? Looks liek it needs to be filled
12:29 PM jymmm: Loetmichel: Yeah, remote boot
12:29 PM Loetmichel: https://www.amazon.de/Dell-P20-Tera1100-3700-Desktop-PC-Tera1100-1000Base-T/dp/B002WV7IVE <- and thats inside there, togehter with an 24" HP display
12:29 PM Loetmichel: no, not remote boot
12:29 PM jymmm: pink_vampire: did you buy that as a kit? I notice the the motor drivers are "plugabble" ???
12:30 PM Loetmichel: the server actually has half a dozen virtual machines with win7 on them
12:30 PM Loetmichel: to test the clients before delivery
12:30 PM pink_vampire: used
12:31 PM * Loetmichel wonders if pink_vampires canines are painted the same kind of flourescent pink ;)
12:31 PM jymmm: pink_vampire: Cool =)
12:32 PM jymmm: pink_vampire: how much?
12:32 PM pink_vampire: $100 and i got with it 2 extra hot end and extra extruder and ton of filament
12:33 PM jymmm: pink_vampire: include pink???
12:33 PM pink_vampire: mmm
12:33 PM pink_vampire: let me see
12:34 PM jymmm: pink_vampire: oh, did you JUST get it???
12:34 PM pink_vampire: yesterday
12:34 PM jymmm: pink_vampire: VERY cool =)
12:34 PM pink_vampire: there is abit of pink pla
12:35 PM jymmm: pink_vampire: Just the way you already have a spot for it and setup, thought you had it for a wwhile =)
12:35 PM jymmm: pink_vampire: and grey =)
12:36 PM pink_vampire: and i have about 6 roles here
12:51 PM jymmm: pink_vampire: o you gonna start doing mail order 3d printing now?
12:56 PM ziper: i have a product i plan on selling
12:58 PM pink_vampire: https://i.imgur.com/hJ6sM6r.png
12:59 PM jymmm: pink_vampire: lol
01:00 PM pink_vampire: https://i.imgur.com/sqGs1Hz.png
01:02 PM jymmm: pink_vampire: googly eyes, where's the tail?
01:02 PM pink_vampire: no tail
01:02 PM jymmm: pink_vampire: ... yet
01:04 PM pink_vampire: it is clear that she is a jellyfish
01:05 PM jymmm: pink_vampire: Well, if she stings you, just be sure to pee on yourself (after you remove power)
01:07 PM pink_vampire: O_OOOOOOOOOOOOOOo
01:08 PM jymmm: pink_vampire: https://www.scientificamerican.com/article/fact-or-fiction-urinating/
01:09 PM pink_vampire: X_x
01:14 PM pink_vampire: https://www.youtube.com/watch?v=x5X6Gp-XMEs OMG
01:27 PM jymmm: pink_vampire: See, you just needed to get pencils
01:28 PM pink_vampire: maybe it will work also for my g0704
01:54 PM roycroft: so if you have schwetty balls peeing might work, but if you drink a lot of beer it won't?
01:55 PM roycroft: https://www.youtube.com/watch?v=bPpcfH_HHH8
01:55 PM roycroft: for those of you unfamiliar with schwetty balls
02:22 PM CaptHindsight: https://www.youtube.com/watch?v=HsexvB2696o Star Wars 3d display in a liquid
03:33 PM flyback: CaptHindsight, probably the same way those phone 3d boxes work
03:34 PM flyback: yep
03:34 PM flyback: 4 sides too
04:09 PM gregcnc: is this height gage worth buying? https://www.ebay.com/itm/312516877518 syyl sync ?
04:10 PM XXCoder: interesting
04:10 PM XXCoder: very different than usual 2 rod type i use at work
04:11 PM gregcnc: Mahr should be good. Just not sure where this older model was made or if that matters
04:11 PM XXCoder: whats your usual tol ranges anyway
04:11 PM gregcnc: I have a vernier that size now
04:13 PM gregcnc: tolerance, oh this will do for now
04:13 PM XXCoder: do yo have say common to have .003" tol or .01" or .03"
04:13 PM XXCoder: at my job its nearly always .01" and sometimes lower
04:14 PM XXCoder: .03" tol jobs is quite rare lol
04:15 PM djdelorie: 0.03" is precision woodworking if you're building a house...
04:15 PM XXCoder: precisely'
04:15 PM XXCoder: thats why im asking about tols.
04:16 PM gregcnc: that tool is .0015"
04:17 PM pink_vampire: gregcnc: it is cost 2 times more then my printer
04:18 PM gregcnc: it's also a real tool
04:18 PM gregcnc: I think original cost was at least 3 times this listing
04:18 PM gregcnc: mitutoyo have similar specs
04:19 PM XXCoder: it looks like cheaper verson but its very tall
04:19 PM XXCoder: well .0005" is pretty good
04:19 PM XXCoder: Accuracy: .0015"/ .002 that'd be useless at shop i work at lol
04:19 PM gregcnc: 12" is tall for a height gage?
04:20 PM XXCoder: yeah i did misread thought it was taller my mistake
04:20 PM gregcnc: that's the thing you can buy a chinaco version for 65USD.
04:21 PM XXCoder: yea thats why im asking what is your usual tolence ranges
04:21 PM XXCoder: because those wont work if you have .001" tol parts sometimes
04:21 PM methods_: no 12" is kinda not tall for height gage
04:22 PM XXCoder: i worked with -.0002 + .0005 parts before its pretty insane
04:22 PM XXCoder: methods_: didnt you read above?
04:22 PM methods_: 12" is nice and easy to move around a surface plate though
04:22 PM gregcnc: unless you step into 5000USD gages, you won't get better than that
04:23 PM XXCoder: yeah
04:23 PM XXCoder: its tough to move over 2 ft tall one to another surface lol expecially since cant grip double rod system!
04:23 PM methods_: that thing looks like it has a pretty large base on it which might give you issues on a smaller surface plate
04:23 PM gregcnc: it's just a caliper on a base
04:24 PM XXCoder: some moron moved it by using double rods once, it had to be sent out to be repaired.
04:24 PM methods_: looks like a good deal on a nice height gage though
04:24 PM gregcnc: yeah the base is 7.5" long
04:24 PM methods_: yeah
04:24 PM methods_: that base is the only thing that might give me issue
04:25 PM methods_: but if you're on a large surface plate it's not going to be a big deal
04:25 PM XXCoder: https://www.ebay.com/itm/Double-Dual-Twin-Beam-12-Dial-HEIGHT-GAGE-001-Digital-Digit-Counter-Gauge/153404066960
04:25 PM methods_: probably be a good thing
04:25 PM XXCoder: dial type is pretty cheap.
04:25 PM gregcnc: i have 18x24
04:25 PM methods_: ah yeah that might kinda suck
04:26 PM gregcnc: zeroing the digital for relative measurements is what I'm after
04:27 PM methods_: i got one of these from shars for the house
04:27 PM methods_: https://www.shars.com/products/measuring/height-gages/24-electronic-height-gage
04:28 PM methods_: at work we have tesa micro-hites
04:28 PM methods_: can't afford that for playin at the house
04:30 PM Tom_L: i was happy with the vise i got from them
04:32 PM XXCoder: gregcnc: https://www.ebay.com/itm/Mitutoyo-Dial-Digital-Counter-Height-Gauge-192-114-0-001-24/362585378033 pretty cheap
04:33 PM XXCoder: problem is you would have to pray they never grabbed the rods.
04:33 PM gregcnc: same price as the Mahr?
04:33 PM XXCoder: $200
04:33 PM XXCoder: techinically not same lol
04:34 PM XXCoder: shipping $20 also actually. not surpised as its 2 ft long
04:35 PM JT-Shop: yea the replacement scope for the gammo came in
04:36 PM methods_: for $40 more you get 24" with that shars one
04:36 PM methods_: no where near as nice as mahr
04:36 PM methods_: but 24"
04:37 PM XXCoder: lol found mitutoyo 24" for 125 bucks but its like verner caliper
04:38 PM XXCoder: that shars one may be suffecent for home shop yeah
04:38 PM Loetmichel: XXCoder: i have a 150mm mitutoyo vernier caliper here
04:38 PM XXCoder: probably need to move around more, and double rod one is really annoyong to move to and away from rock.
04:39 PM Loetmichel: 100 times better and easier to use than the $12 digital ones at teh company
04:39 PM XXCoder: have to use one hand on base, and lightly hold top of gauge to keep it upwards
04:39 PM Loetmichel: but i would NEVER use that to score some sheet metal like i do with the cheap digital ones all the time
04:40 PM XXCoder: one guy just grabbed double rods and base moved it. it failed certification and got rebuilt
04:40 PM methods_: two rods at one time!
04:40 PM methods_: that's a lot of rods
04:40 PM methods_: he must really like to hold rods
04:40 PM XXCoder: lol
04:40 PM XXCoder: Loetmichel: dont have replacable blade eh
04:57 PM Deejay: gn8
05:05 PM Loetmichel: XXCoder: yes ;)
05:07 PM XXCoder: lol ok
06:05 PM XXCoder: Loetmichel: still waiting for my cheap shit mic to arrive :( its annoyionmg lol
06:06 PM XXCoder: i still wonder whats chances of accuracy and precision lok
06:06 PM XXCoder: https://www.aliexpress.com/item/0-25mm-0-01mm-Carbon-Steel-Outside-Micrometer-Caliper-Precision-Gauge-Vernier-Caliper-Measuring-Tools/32904069447.html
06:24 PM pink_vampire: XXCoder: 0,01mm micrometer micro = 0.001
06:25 PM XXCoder: yea, its 3 bucks so quit questionable on quality tho :)
06:25 PM Tom_L: probably just a C clamp
06:28 PM XXCoder: yeah tom it would be great joke at work - oops dropped!
06:28 PM methods_: yeah never let a welder use your mic's or that's what they'll be
06:29 PM Tom_L: XXCoder then pick it up and clamp it in a vise to check a part
06:29 PM XXCoder: yech! someone did it to your mic?
06:29 PM methods_: not mine but one of the guys in my shop
06:29 PM methods_: couldn't find his mic and the welders had it using it as a clamp
06:30 PM XXCoder: thats worse.
06:30 PM XXCoder: did welders buy a replacement?
06:30 PM Tom_L: especially with weld spatter all over it
06:30 PM methods_: yeah
06:30 PM methods_: they were dead
06:30 PM Tom_L: replacement clamp or.... ?
06:30 PM methods_: weldurrs
06:31 PM XXCoder: i would be pissed if someone used my starret mic that way. it was made in 1952
06:32 PM methods_: that would be rightful anger
06:32 PM Tom_L: almost excuseable manslaughter
06:32 PM methods_: measured vengeance
06:33 PM methods_: you could use the mic's to measure how close he came to death when the beatings stopped
06:33 PM XXCoder: lol
06:34 PM Tom_L: so how fast should i spin this 4 flute carbide endmill in steel?
06:34 PM Tom_L: got a fair idea but i generally don't run steel
06:34 PM methods_: cs*3.86/4
06:35 PM methods_: good carbide i run at 1000sfm
06:35 PM Tom_L: in steel?
06:35 PM methods_: in plain carbon yeah
06:35 PM Tom_L: heh my spindle motor would burn up :D
06:35 PM methods_: yeah
06:35 PM methods_: you'll have to find a happy medium
06:35 PM Tom_L: i know
06:35 PM methods_: max rpm?
06:36 PM Tom_L: i ran some manual tests last night
06:36 PM methods_: and diameter?
06:36 PM Tom_L: i'll probably run around 2k rpm
06:36 PM Tom_L: .250 D em
06:36 PM methods_: yeah you'd have to spin that puppy at 10-12k for correct feeds and speedds
06:37 PM methods_: at 2k you'll just have to adj the feed
06:37 PM Tom_L: gonna start around .0003" chip load
06:37 PM methods_: 2k .002/tooth
06:37 PM Tom_L: see what happens
06:37 PM Tom_L: i don't think the mill would do that
06:37 PM methods_: maybe .001/tooth
06:38 PM methods_: ohhh
06:38 PM methods_: yeah try that
06:38 PM methods_: you'll just have to play it by ear
06:38 PM Tom_L: i'm more worried about the thread mill
06:38 PM Tom_L: .595 diameter
06:38 PM Tom_L: 6 flute
06:38 PM methods_: oh
06:38 PM methods_: wow
06:38 PM methods_: just take light cuts i guess
06:39 PM methods_: and spring passes
06:39 PM Tom_L: i'm doing 3 passes in aluminum
06:39 PM Tom_L: may not need to but i am
06:39 PM methods_: yeah
06:39 PM methods_: probably not a bad idea
06:39 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Thread_mill2.jpg
06:39 PM Tom_L: the big one
06:40 PM methods_: nice little set
06:40 PM Tom_L: should cover anything i need
06:40 PM methods_: id thread i'm assuming?
06:40 PM Tom_L: i can do both with it but yes
06:41 PM Tom_L: wrote the macro for it for my cad cam
06:41 PM Tom_L: works nice
06:41 PM methods_: alot cheaper than buyin a tap
06:41 PM Tom_L: i figure i got a tap n die set for inch and metric there
06:42 PM methods_: definitely
06:42 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Mill_holder7.jpg
06:42 PM Tom_L: there's the part in aluminum
06:42 PM methods_: oh yeah threads look beautiful
06:42 PM methods_: nice and clean
06:42 PM Tom_L: cross thread too
06:43 PM Tom_L: but hard to see
06:43 PM methods_: yeah i see it
06:43 PM methods_: i thought you tapped that
06:43 PM Tom_L: heh, no
06:43 PM methods_: you thread milled that
06:43 PM methods_: wow
06:43 PM XXCoder: lovely.
06:43 PM Tom_L: using a sherline spindle :)
06:43 PM XXCoder: any external threads example like bolt?
06:44 PM methods_: nice
06:44 PM methods_: the threads look a little flat on the cross tapped one
06:44 PM methods_: but still
06:44 PM methods_: for that size looks good for milled
06:44 PM Tom_L: https://www.youtube.com/watch?v=JkAAWT7Nxd8
06:45 PM methods_: smooth as buttah
06:45 PM methods_: show off
06:45 PM Tom_L: hha
06:45 PM Tom_L: hah
06:45 PM methods_: :p
06:46 PM Tom_L: i cut another pocket in the jaws for the steel part
06:46 PM Tom_L: the alum was slightly over 1"
06:46 PM methods_: machined jaws FTW
06:46 PM Tom_L: i've got a small pile of em
06:47 PM Tom_L: i lay that part down even with the right end of the jaw and run the cross holes
06:47 PM Tom_L: one program
06:47 PM methods_: knob for something?
06:48 PM Tom_L: sherline mill holder
06:48 PM Tom_L: fits the sherline thread
06:48 PM methods_: ahhhh
06:48 PM Tom_L: i'm gonna make some for common drills so i can 'tool change' them instead of using the drill chuck
06:49 PM methods_: good idea
06:49 PM Tom_L: the chuck sticks down too far to be very useful
06:50 PM methods_: yeah and your height offsets are always going to be suspect changing bits
06:50 PM Tom_L: the cross thread took every bit of reach on that tiny cutter
06:50 PM methods_: you gain some z and have repeatable holders
06:51 PM Tom_L: yup
06:51 PM Tom_L: the trick is don't drill them quite all the way thru so they can butt against the holder
06:51 PM Tom_L: in case the set screw quit setting :)
06:52 PM Tom_L: i should have collet holders and collets but this is a ghetto op here
06:53 PM methods_: i have the tormach style ones for mine
06:53 PM methods_: they seem to be a decent compromise
06:56 PM Tom_L: it's mostly for messin with linuxcnc and playing anyway
07:02 PM Tom_L: methods_, the cross thread is a little shallow, needs about .004" more
07:02 PM Tom_L: was a first run for it
07:12 PM pink_vampire: https://www.thingiverse.com/thing:624814 very very soft jaws
07:12 PM XXCoder: theres even 123 block model there lol
07:13 PM pink_vampire: i need to print set of gage blocks
07:14 PM Tom_L: for what?
07:14 PM XXCoder: tom no idea it wouldnt be 1"x2"x3" to close tol thats for sure
07:15 PM pink_vampire: XXCoder: you just need to touch them on the 3d printed surface grinder
07:16 PM XXCoder: lol
07:34 PM XXCoder: black 3.0 is shipping soon! i cant wait. :D
07:38 PM pink_vampire: why?
08:45 PM XXCoder: pink_vampire: dunno its fun?
08:45 PM XXCoder: it asorbs 99% of light so its very black
09:19 PM pink_vampire: XXCoder: how much did you payed for it?
09:19 PM XXCoder: oh its kickstarter sometimes prices is higher at kickstarter than afterwards
09:19 PM XXCoder: 2 bottles for 52 bucks, shipped all way from europe
09:19 PM XXCoder: 2 liters? not too sure on size lol
09:20 PM XXCoder: https://www.kickstarter.com/projects/culturehustle/the-blackest-black-paint-in-the-world-black-30
09:20 PM XXCoder: ah 150 mL
09:21 PM pink_vampire: those are very nice nails!
09:23 PM XXCoder: whos nails?
09:24 PM pink_vampire: in the link you posted
09:24 PM XXCoder: yeah tgheres a few depending if include video or not :)
09:24 PM XXCoder: including kapoor's middle finger in pinkest pink
09:25 PM pink_vampire: https://ksr-ugc.imgix.net/assets/022/980/202/74f58f997124a4a08d361fafe1907b43_original.jpg?ixlib=rb-1.1.0&crop=faces&w=1552&h=873&fit=crop&v=1548797854&auto=format&frame=1&q=92&s=43725e97ac5c18fa15b1e1d78653db20
09:25 PM XXCoder: btw if you like pink maybe buy pinkest pink at their site lol its so pink cameras cannot capture how pink it is.
09:25 PM XXCoder: ahh that
09:27 PM pink_vampire: https://www.culturehustleusa.com/products/pink-50g-powdered-paint-by-stuart-semple
09:28 PM XXCoder: yeah, that. you just add water to certain thickness and paint. arylic based
09:29 PM XXCoder: first, make sure that you are not anish kapoor, nor giving it to him, or somehow get it to him lol
09:29 PM XXCoder: dumb really but funny
09:31 PM pink_vampire: i need about a bucket to paint the walls here
09:32 PM XXCoder: lol yeah sadly its so expensive
09:32 PM XXCoder: great for small projects
09:32 PM pink_vampire: :(
09:33 PM XXCoder: they sell bunch of very odd stuff besides black 2.0 (soon 3.0) pinkest pink, gloittery glitter etc
09:33 PM XXCoder: so recommand look around lol and hold tight to your wallet
09:33 PM XXCoder: or purse
09:42 PM pink_vampire: very cool stuff
09:42 PM XXCoder: yeah
10:28 PM R2E4: hi all
10:28 PM R2E4: How would I install the simulator?
10:31 PM R2E4: linuxmint 19
