12:46 AM Elmo40: CaptHindsight, ahh, the autodesk patent b.s.
12:50 AM Elmo40: the company that came up with this non-planar, around 2012'ish, was bought by autodesk in 2014'ish... but they sat on it.
12:50 AM Elmo40: so i say fuck'em for sitting on this!!
12:50 AM Elmo40: code is out in the wild now!
12:50 AM Elmo40: other than take down the GIT repo, there isn't anything they can do to the community. other than keep sitting on it!
01:20 AM Deejay: moin
01:22 AM jesseg: mornin
01:33 AM Elmo40: moo?
01:33 AM Elmo40: time for sleep! 0230 here...
02:37 AM pink_vampire: Hi everyone
03:18 AM Loetmichel: *GIGGLE* just worked a bit on our (win) domain sever... found a file called "Login.bat"... inside: "REM Loginscript der firma Cordnes (c) 05.06.2009 by [IT consultant]" First: Our company is called Cordsen! second: (c) for a 20 line script? REALLY?!? Funny is that that script is still in use ;)
03:39 AM pink_vampire: I need to replace the HDD in my laptop
03:40 AM pink_vampire: Loetmichel: if it works - don't fix it
04:19 AM XXCoder: Elmo40: yeah arylic tube for two of expensive shop lights i got free lol
04:20 AM XXCoder: Elmo40: $88 for oem glass tube lol forget that
04:20 AM XXCoder: Loetmichel: nothing as immortal as short term programming fix
04:22 AM XXCoder: pink_vampire: saw that you installed it. nice
04:55 AM jthornton: morning
04:56 AM XXCoder: morning
04:57 AM jthornton: I wonder if I should update my marlin firmware in the old printer
04:58 AM XXCoder: too bad theres no way to backup that
04:58 AM jthornton: yea I had forgot about that
05:00 AM Tom_L: morning
05:00 AM Tom_L: you can back it up
05:01 AM jthornton: how?
05:02 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/how_to/atmega168/using_avrdude_index.php
05:02 AM Tom_L: i may not have read from device there but i'm pretty sure you can and save it to a file
05:02 AM Tom_L: near the bottom
05:04 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/avr/avrdude/avrdude-doc-5.10.pdf
05:04 AM Tom_L: might help find the switch
05:04 AM Tom_L: i know you can because i've saved the 2560 firmware before
05:06 AM Tom_L: flip might let you but i'm not sure
05:06 AM Tom_L: or dfuprogrammer
05:13 AM Tom_L: you may want to save the fuse settings too
05:14 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/boards/USBTiny_Mkii/USBTiny_Mkii_User_manual_index.php
05:14 AM Tom_L: for using flip
05:16 AM Tom_L: or are you using an arm chip on it now?
05:16 AM jthornton: ramps what ever that is
05:16 AM Loetmichel: XXCoder: works for every blue collar job as well "Nichts ist so beständig wie ein provisiorium!") is a germany proverb
05:16 AM Tom_L: i just assumed marlin meant avr
05:16 AM XXCoder: lol
05:17 AM Loetmichel: (nothing is so long lasting as a temporary fix!)
05:17 AM jthornton: RAMPS 1.4 shield, an Arduino Mega 2560 board (or a clone)
05:17 AM Tom_L: right
05:17 AM Tom_L: i've got a clone board too
05:17 AM Tom_L: just no ramps
05:18 AM jthornton: I'm trying to refresh my memory now lol
05:20 AM Tom_L: i had it written down somewhere but can't seem to find it right now
05:20 AM Tom_L: been quite a while...
05:20 AM jthornton: XXCoder, what printer is ours a clone of?
05:20 AM XXCoder: errm flsun is name of clone
05:20 AM XXCoder: damn a second
05:20 AM XXCoder: prusa
05:20 AM Tom_L: shouldn't matter, what matters for this is that it's a 2560 avr chip
05:20 AM jthornton: ah ok
05:20 AM XXCoder: some model of prusa
05:21 AM Tom_L: iirc on that i backed it up with the usb port using flip
05:21 AM XXCoder: offical. https://dqzrr9k4bjpzk.cloudfront.net/images/2442119/874243423.jpg
05:22 AM XXCoder: can see its higher quality. lol
05:22 AM jthornton: yep that's pretty much it
05:23 AM Tom_L: if it doesn't have a bootloader then you can't use flip with it you need avrdude for that
05:23 AM jthornton: now that the flsun is printing nice I need to clean it up some
05:23 AM Tom_L: flip works with usb enabled avr chips
05:24 AM jthornton: iirc I use arduno to load marlin
05:24 AM Tom_L: it's just a front end for avrdude
05:26 AM jthornton: https://www.thingiverse.com/thing:2230565
05:27 AM Tom_L: their gui may have a save option as well
05:29 AM jthornton: the arduino?
05:30 AM XXCoder: ramps certainly but besides that dunno]
05:30 AM XXCoder: I wonder if my ramps is compitable lol
05:31 AM jthornton: compatible with what?
05:31 AM XXCoder: that case
05:31 AM jthornton: should be
05:32 AM XXCoder: is yours flsun clone too?
05:32 AM jthornton: yea same as yours
05:32 AM XXCoder: I guess it is then :)
05:32 AM XXCoder: part to repair it is still on way lol
05:35 AM jthornton: I may just draw one up in SW... but I sorta like this one and using the thingview I see it attaches to the rail
05:36 AM XXCoder: it does look decent.
05:40 AM jthornton: started putting the Ender 3 together yesterday
05:40 AM XXCoder: printing new printer with old obne?
05:40 AM jthornton: no
05:40 AM Loetmichel: ender3 doesent have any printed parts IIRC
05:40 AM Loetmichel: or even "print-able"
05:41 AM XXCoder: oh
05:41 AM jthornton: https://www.amazon.com/gp/product/B07BR3F9N6
05:41 AM XXCoder: so its not reprap style
05:41 AM XXCoder: thats pretty decent looking
05:41 AM XXCoder: larger and not too expensive
05:42 AM jthornton: looks pretty good so far, you could assemble it in 2 hours but to do a proper job it takes longer
05:42 AM jthornton: I had to machine the ends of the uprights square
06:01 AM jthornton: hmm I'm not finding my old marlin files with the configuration for the flsun
07:45 AM t4nk-freenode: so.. I use inkscape to export some g-code for my minicnc, I sometimes start camotics to visualise it.. But what would some good options be on linux? what 'cam' software (or whatever the heck it all means) could you recommend me? What tools are there for linux? Somehow I think camotics isn't really that great of a program, am I right?
07:48 AM t4nk-freenode: as in, it seems a bit limited, somehow I'd like to control the simulation better; camotics just rambles on and on, you can slow it down or change direction... but there's no stopping it. Wondering if there is anything better
07:48 AM Elmo40: XXCoder, make sure it doesn't melt!
07:49 AM Elmo40: lights can heat up a lot.
07:49 AM t4nk-freenode: and, Tom_L, I believe it was you who said something like 'nearly all cam software is able to convert arcs to lines' when I asked about it.
07:51 AM Elmo40: XXCoder, you can at the very least copy down the current settings.
07:51 AM Elmo40: M503
07:51 AM t4nk-freenode: I've been revisiting my arc routine, and I discovered that for some purposes.. arcs don't even really matter, and you can just ignore them.. that's kewl ;)
07:51 AM Elmo40: if those work fine, then create a new Marlin and change them all over
07:53 AM Elmo40: arcs are tiny lines. depends on how small of a segment you want it will give you smoother or more course of an 'arc'.
07:53 AM Elmo40: especially in the world of steppers. there is no fluid movement. just tiny jumps.
07:55 AM t4nk-freenode: yeh, and in the world of 'mini cnc' .. it becomes even more clear when you are fixed to a raster of about 250 square pixels ;)
07:55 AM t4nk-freenode: but that's ok really
07:55 AM Loetmichel: Elmo40_ depends
07:56 AM Loetmichel: you can drive steppers with two 90° sines
07:56 AM Loetmichel: then its smooth as silk
07:56 AM t4nk-freenode: but then you lose some valuable torque I think
07:56 AM Loetmichel: nope, just in between the steps
07:57 AM Loetmichel: on the step "corners" you have the full torque
07:57 AM Loetmichel: or in other words: the torque will pulse with the steps
07:57 AM Loetmichel: not the movement
07:57 AM t4nk-freenode: yeh, so, where's the difference? lost torque is lost torque isn't it? if you're dragging a pen
07:57 AM Loetmichel: if you are dragging a pen you will not notice it
07:58 AM Loetmichel: only if you move/accelerate/decelerate VERY close to max torque
07:58 AM Loetmichel: then it can happen that you have step loss
07:59 AM Loetmichel: but as it is a safety practice to use only 80% of max torque of steppers anyways (if open loop) there is no drawback in sine driving
07:59 AM t4nk-freenode: but the resolution will still be the same eventually
07:59 AM gregcnc: the torque available to position to the micro step is small, but you have to exceed full rated to to lose a step
08:00 AM Loetmichel: nope. it will not be as high as the "microsteps" suggest, usually about half because of nonlinearitys in steppers between the full steps, but still significantly higher than full steps
08:01 AM t4nk-freenode: well, since I'm messing with the original driver ic's that were in the dvd players.. ah... eh, yes of course.. that was silly of me; resolution will increase indeed
08:02 AM t4nk-freenode: nehow, messing with the original driver ic's I decided to stick with 'full step' since it was easier for me. I guess I could go half step if I would mute the driver chips
08:02 AM Loetmichel: i.e: if you have 100 steps per mm at full steps and have 16x microsteps you dont have 0,0000625 resolution but rather 0,000125
08:02 AM t4nk-freenode: yes
08:03 AM t4nk-freenode: though I must say.. in the setup I have right now.. a full step is .15mm for me, and really.. it is rather impressive still!
08:03 AM Loetmichel: sure
08:03 AM Loetmichel: especially if you move a felt pen like an edding or sharpie
08:04 AM Loetmichel: you dont see 0.15mm there ;)
08:04 AM t4nk-freenode: but in time I'll buy some driver chips and perhaps some better steppers
08:05 AM Elmo40: Tom_L, in your link i wasn't able to figure out which tools to use for the TinyMKII.
08:05 AM Elmo40: https://www.microchip.com/development-tools/
08:05 AM Loetmichel: its surprising how good the result can be if you put absolute crap in.
08:05 AM Elmo40: anything suitable on this page? the ATMEL Studio?
08:05 AM Loetmichel: my first CNC mill was about every error you can make... -> http://www.cyrom.org/palbum/main.php?g2_itemId=2859&g2_imageViewsIndex=1
08:06 AM t4nk-freenode: although I must say that I now even did experiments with a drill in my device, and again; impressive! I managed to slip a drill into the device and was able to drill holes and such... I now put a pen back in, but I feel like pushing this, making a new construction, keep using dvd stepper motors( maybe doubling up on them) and try some neat stuff
08:06 AM Loetmichel: ... and it STILL produced decent parts: http://www.cyrom.org/palbum/main.php?g2_itemId=2925
08:06 AM Loetmichel: :-)
08:06 AM Elmo40: Loetmichel, which drivers give this 'smooth sin wave' ?
08:07 AM Loetmichel: Elmo40: no idea, i know there are drives out there that can do 1024 microsteps. thats as close to sine as the stepper can follow i imagine
08:08 AM Loetmichel: a 1k microsteps it will probably not move for a handful microsteps from stick torque in the bearings alone ;)
08:08 AM Elmo40: true
08:08 AM Loetmichel: i HAVE driven steppers with two sine generators and a stereo amplifier... they turn like silk then
08:09 AM t4nk-freenode: Loetmichel, yeh, that's nice! they seem like quite big steppers you have there... I'm convinced my dvd steppers can do fairly well..
08:09 AM Elmo40: i think the 256 micro is as many as anyone would ever need. though 1/16 is really 'good enough' for anyone.
08:10 AM t4nk-freenode: I was thinking about using a threaded rod to increase my work area to a bit larger than the 39mm I have right now
08:10 AM t4nk-freenode: yeh, like a 6-bit dac is enough too
08:11 AM t4nk-freenode: nehow, threaded rod, and a dvd stepper at each side, opposite directions in tandem
08:12 AM t4nk-freenode: however, since I started fooling around, I'm really gaining enthusiasm I must say ;) there's a host of neat stuff you can do with it
08:13 AM t4nk-freenode: right now I'm only focused on being able to drill holes, I want to make pcb's my style, I got some neat ideas and I think I can get it done
08:15 AM t4nk-freenode: haven't got any bits or drills yet though; I was wondering how a .25mm drill would be, I believe I saw some bits online.. .25mm for a hole seems really small to me
08:18 AM t4nk-freenode: https://unsee.cc/39616115/ this is a test I did .. I think it's kewl ;)
08:19 AM t4nk-freenode: the big hole is nearly through and through( didn't intend to do that btw, because I have a little glass plate)
08:20 AM t4nk-freenode: but anyhow.. considering this is done with a tiny machine.. dunno, I get a good feeling about the potential it has
08:21 AM t4nk-freenode: I didn; t use a drill here btw, but some cone-shaped pointy thingie that came with my dremel
08:49 AM naftilos76: Hi everyone, it is my first time with a 3018pro cnc from aliexpress and i would like to ask this: What is the best way of going from a vector graphics file generated by let's say inkscape to g-code. Is there any anything apart from inkscape in linux that can help me generate g-code files?
09:00 AM JT-Shop: LOL print time left 5 days
09:00 AM JT-Shop: iirc inkscape has some kind of g code generator
09:01 AM JT-Shop: for simple stuff just use a simple g code generator or code by hand
10:12 AM Tom_L: Elmo40, i haven't kept up with it after microchip bought them out
10:13 AM Tom_L: i doubt the newer tools will work with mine
10:17 AM Tom_L: avrdude should still work
11:01 AM jym: morning folks
11:30 AM naftilos76: Hi, this is probably a novice question but hey i am just starting with my first cnc. Is feed rate the speed of the spindle while cutting?
11:30 AM naftilos76: i mean the x/y distance
11:33 AM jesseg: feedrate is the linear motion of the xyz axes
11:33 AM jesseg: naftilos76, so if it was 1in/minute and it was moving only in the x direction, x would be moving 1 inch each minute.
11:34 AM jesseg: If it's moving equally in x and y, then each x and y will be moving less than 1 inch/minute, but the tool will still be moving at 1 inch per minute diagonally.
11:34 AM naftilos76: jesseg: yea exactly thanks
11:41 AM Loetmichel: t4nk-freenode: DONT use a threaded rod as linear drive
11:41 AM Loetmichel: use at least an acme thread
11:42 AM Loetmichel: normal imerial/metric threads are to steep, they act like a cutter for the nut
11:42 AM Loetmichel: took less than 5 hours and then the brass nut on that PMMA gantry "mill" in the picture above was a nice 5mm hole instead of threaded
11:42 AM Loetmichel: M5
11:43 AM Loetmichel: thats what i meant when i said: i did everything wrong that could be wrong
11:44 AM Loetmichel: wrong structral material (PMMA isnt really good for rigid constructions), wrong threads, way to weak steppers, way to weak dremel (proxxon) and the linear ways made of milled PMMA and singe ball bearings were not good either
11:44 AM Loetmichel: it DID work but was no where optimum
11:53 AM JT-Shop: lol print time left is down from 5.5 days to 1.5 days
11:56 AM jesseg: I tried using a threaded stainless rod in a stainless nut *once.*
11:57 AM JT-Shop: ouch
11:57 AM jesseg: yeah.. stainless sliding on stainless is about as bad as it gets :P
11:57 AM JT-Shop: without tons of moly sure to seize up
12:21 PM t4nk-freenode: mmmmm... I was half on my way to the hardware store, Loetmichel ;)
12:22 PM t4nk-freenode: too bad I aint know nothing about anything really, but I figure I won't be able to get 'acme' for 1.15euro/m?
12:22 PM t4nk-freenode: *sigh*
12:22 PM t4nk-freenode: I was thinking of going out and buying me a meter of m4 or m5 with nuts, see what I could do
12:23 PM t4nk-freenode: I see your point though
12:23 PM Loetmichel: t4nk-freenode: you are german?
12:23 PM t4nk-freenode: though I must say that there is a lot of weight on that axis of yours, right.. that helps.. and then did you mean brass nut? that would be softer too, no?
12:24 PM t4nk-freenode: nein, bin ich leider nicht ;)
12:24 PM t4nk-freenode: dutch
12:24 PM JT-Shop: if your expectations are low you will be ok
12:24 PM Loetmichel: ah, but european
12:24 PM jesseg: t4nk-freenode, My brother was remodeling a little sherline mill and he got some semi-acme thread and made delrin nuts.
12:24 PM jesseg: he has almost no lash and seems very pleased.
12:24 PM Loetmichel: try a local hardware supplier, often they have "trapezgewinde" rods and nuts
12:24 PM Loetmichel: works WAY better than metric thread
12:25 PM t4nk-freenode: yes, me expectations are rather low, But... they were low when I started my mini cnc 'plotter'.. and that turned out quite impressive
12:25 PM t4nk-freenode: my expectations are: better than that
12:25 PM jesseg: had to get a special tap for making the delrin nuts though, but it wasn't too expensive as I recall
12:25 PM t4nk-freenode: yeh, I just did a search, Loetmichel, 'trapeziumdraad' is the dutch term
12:25 PM Tom_L: undersize?
12:25 PM t4nk-freenode: I'll ask for it
12:27 PM Tom_L: JT-Shop, what are you printing that went from 5+ days to ~1?
12:28 PM Tom_L: sounds about like a windows update bar graph only backwards
12:28 PM JT-Shop: yea down to 1 day time left at 15% printed lol
12:28 PM JT-Shop: no windblows
12:28 PM JT-Shop: cura says 14 hours which might be closer to correct
12:28 PM Tom_L: did you find your config?
12:29 PM JT-Shop: never did, gotta look on some old hard drives
12:30 PM Tom_L: maybe you should print it next time and tape it to the printer :)
12:33 PM t4nk-freenode: *ouch* this trapezium is 15x as expensive as a normal rod
12:33 PM t4nk-freenode: they're steel though
12:38 PM t4nk-freenode: well, gonna go out, see what they got.. later.
12:59 PM miss0r: 'evening
12:59 PM Tom_L: afternoon
01:00 PM miss0r: anything interresting happending?
01:01 PM Tom_L: suspiciously quiet here
01:01 PM miss0r: no news is good news? :)
01:04 PM Tom_L: niece had a baby overnite
01:04 PM miss0r: congrats
01:04 PM miss0r: and my condolenses to her future sleep
01:05 PM Tom_L: #2
01:05 PM miss0r: I stand by that statement
01:05 PM Tom_L: move to neonatal care a bit ago
01:06 PM miss0r: A serious case?
01:06 PM Tom_L: could be
01:06 PM Tom_L: i'm not there
01:06 PM miss0r: my sister-in-law is struggling with the exact same at the moment.
01:06 PM miss0r: but it would seem they are on top of it now, though
01:36 PM * JT-Shop gives up for now trying to get the Z stepper mount to be square to the rail and shims it with some paper
02:01 PM * t4nk-freenode sits at his desk, dazedly staring at a 5mm threaded rod
02:01 PM t4nk-freenode: was already on my way home when I discovered that I had picked some stainless nuts and bolts to go with it...
02:03 PM t4nk-freenode: returned them for galvanised, but captainhindsight will probably tell me I should have gone with stainless nuts sometime soon
02:06 PM miss0r: man I hate cleaning the shop.
02:07 PM miss0r: Which is why I always put it off... which in turn ends up being even worse, so I can hate it even more...
02:15 PM sensille: miss0r: if you put it off long enough, cleaning can actually be very satisfying
02:15 PM miss0r: cue my situation right now ;)
02:15 PM miss0r: drillpress, lathe and mill is now clean
02:15 PM miss0r: well.. I still need to empty and clean the chiptray on the mill
02:15 PM miss0r: then the rest of the shop...
02:21 PM JT-Shop: down to 12 hours print time left lol
02:24 PM Loetmichel: t4nk-freenode: PLEASE use some thread cutters on the rods and buy brass nuts
02:24 PM Loetmichel: (the thread cutters to smoothen out the thread on the rods)
02:24 PM Loetmichel: and the brass nuts because stainless on stainless welds itself together
02:25 PM Loetmichel: t4nk-freenode: some suggestions on how to make linear ways:
02:25 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=359
02:26 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=347
02:26 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=344
02:26 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=335
02:26 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=8872
02:26 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=8875
02:27 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=8884
02:27 PM Loetmichel: just a suggestion though
02:27 PM pink_vampire: Loetmichel: you are doing it wrong https://i.imgur.com/yozWBh9.png
02:28 PM Loetmichel: pink_vampire: yeah, if i want to mill gouda that would be approbiate
02:28 PM Loetmichel: i know the MPCNC
02:29 PM Loetmichel: and i dont think its worth the extrusions and print time
02:29 PM Loetmichel: just an oprinion though
02:30 PM Loetmichel: it may be good enough for milling plywood and plastics
02:30 PM pink_vampire: all I want from it is wood and plastic
02:30 PM Loetmichel: yeah, then it would be ok
02:31 PM Loetmichel: if you have the time to do 1mm max cutting depth and go SLOOOW
02:31 PM pink_vampire: and the ability to scale up
02:31 PM djdelorie: my whole cnc machine is wood and plastic... :-(
02:31 PM Loetmichel: djdelorie: mine were, too
02:32 PM pink_vampire: Loetmichel: as long as it cut even 0
02:32 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=4935&g2_imageViewsIndex=1
02:32 PM pink_vampire: even 0.5 mm DOC is fine
02:32 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=11205&g2_imageViewsIndex=1
02:33 PM Loetmichel: i used loads of marine plywood though (called "siebdruckplatte" in germany)
02:33 PM Loetmichel: ... not REALLY wood any more
02:33 PM pink_vampire: I have NO room for a cnc router here
02:33 PM Loetmichel: more like a wood fibre reinforced resin
02:34 PM Loetmichel: and a SHI*LOAD of Spax screws ;)
02:34 PM pink_vampire: I want to be able to take the conduit out and store the printed parts in a box
02:34 PM Loetmichel: pink_vampire: mount the CNC upright on the wall at a slight angle
02:35 PM Loetmichel: so it takes less room
02:35 PM Loetmichel: also the swarf will fall off, less cleaning ;)
02:36 PM pink_vampire: walls.. when did I saw one??
02:45 PM XXCoder: Elmo40: no worries on that. leds is on massive heat sink. oem may be glass but reason why its thrown is because company went cheap and bought arylic tubes which got beaten in machine by chips etc and broke few times
02:45 PM XXCoder: so problem was breaking and not melting. :) since i dont plan to put it in machine it wont be issue
02:49 PM * t4nk-freenode takes a short break from cutting the rod to tend to his injuries
03:14 PM JT-Shop: XXCoder: almost half way printing the ramps box
03:14 PM XXCoder: nice :)
03:14 PM JT-Shop: when I first started it said 5 days to print lol
03:15 PM XXCoder: microsoft minutes lol
03:15 PM XXCoder: it can be one second long, or it may be days long lol
03:15 PM JT-Shop: seems like OctoPrint does a bad job of estimating the time
03:16 PM pink_vampire: JT-Shop: I'm after 8:50 hours of print, and now I'm printing it again!
03:16 PM JT-Shop: what happened?
03:16 PM pink_vampire: it was good, but I need 2

03:18 PM JT-Shop: lol
03:19 PM pink_vampire: I'm not brave enough to watch actual paint drying
03:21 PM JT-Shop: I have a camera on the prusa clone
03:23 PM pink_vampire: I have also a camera
03:23 PM pink_vampire: the pan something
03:24 PM pink_vampire: Wyze Cam Pan

04:05 PM Deejay: gn8
04:36 PM skunkworks: ~
05:12 PM _unreal_: I cant believe I didnt tink of it sooner
05:13 PM _unreal_: I'm making interferience parts right now in my cad drawing
05:13 PM _unreal_: so that when I mill them "with luck tonight" they wont fit easy
05:13 PM _unreal_: I will have to use a clamp to force them together
05:13 PM _unreal_: which will be nice
05:13 PM _unreal_: Main reason being that it will FORCE self align the parts
05:18 PM Tom_L: or crack em
05:23 PM _unreal_: only out by a few thou
05:24 PM _unreal_: and crack.. not likely
05:24 PM _unreal_: I'm buiding this with starboard. you can flex the crap out of it before it rips
05:26 PM _unreal_: Very hard to crack starboard
05:34 PM t4nk-freenode: I'm sure if you put your intellect to it, you will succeed though
05:35 PM t4nk-freenode: sooner 'then' later 'to' ;)
05:36 PM jthornton: what is starboard?\
06:00 PM Tom_L: i'm guessing some marine construction material for interiors
06:01 PM SpeedEvil: IIRC recycled polypropylene cast sheet
06:01 PM Tom_L: https://www.kingplastic.com/products/king-starboard/
06:16 PM andypugh: Cheaper than I anticipated: http://www.charmhigh-tech.com/sale-7971156-economic-model-chmt36va-smt-pick-and-place-machine-top-and-bottom-camera-externel-pc.html
06:16 PM andypugh: SMT pick and place machine, with feeders and vision etc
06:17 PM Elmo40: cool
06:17 PM Elmo40: time to pick-n-place coffee beans in my grinder for me
06:18 PM Tom_L: andypugh you lookin for one?
06:18 PM andypugh: Not actively.
06:18 PM jthornton: 355mm x 355mm not bad
06:18 PM andypugh: Juat saw them being discussed somewhere.
06:19 PM andypugh: I have thought of making one, though the assembly cost for the STMBL boards had made was only about $4 per board for 100+ components.
06:19 PM CaptHindsight: andypugh: did they successfully avoid any use of LCNC in the SMT PnP?
06:20 PM andypugh: I think so, it appears that with the cheapest one you need to supply an Windows 7 PC.
06:21 PM CaptHindsight: a few years ago there was no China grown CNC controller
06:21 PM CaptHindsight: I wonder if they have some standard windoze CNC controller app they all copy and modify?
06:23 PM CaptHindsight: some ship with mach3 from China
06:28 PM CaptHindsight: after the 2013 LCNC meetup in Wichita I went back to China to work on 3D printers, everyone there wanted to reinvent the wheel vs use LCNC
06:29 PM CaptHindsight: they wanted windowz and control over USB
06:34 PM andypugh: Yes. Well, saves us a lot of support headaches
06:46 PM SpeedEvil: Windows. The other free software OS.
06:48 PM CaptHindsight: free to ~$3 for a CD back then
06:50 PM CaptHindsight: https://en.wikipedia.org/wiki/Kylin_(operating_system)
07:08 PM jthornton: andypugh, did anyone find a replacement for the STMBL part that was discontinued?
07:09 PM andypugh: They have a version in development that uses discrete devices
07:10 PM jthornton: cool
07:16 PM jthornton: hmm the ender 3 home switches are quite a bit off center of the build plate
07:18 PM _unreal_: finally found my dremel 1/8th drill bits
07:18 PM _unreal_: YAY
07:19 PM _unreal_: AND I found a dremel 3 flute upcut bit
07:19 PM _unreal_: I need to grind off the bottom though :( its got a POINT I need it to be flat
07:19 PM _unreal_: point and a non cutting point at that
07:21 PM CaptHindsight: https://imgur.com/gallery/yiRseYd
07:24 PM _unreal_: wonder how many hours of MILL time that was?
07:25 PM _unreal_: looked like a 3/8-1/2" end mill bit for the rough in
08:23 PM _unreal_: shhhh
08:25 PM Tom_L: ok
08:26 PM _unreal_: heh
08:29 PM _unreal_: so whats new?
