04:49 AM jthornton: morning
04:49 AM XXCoder: hey
05:01 AM Tom_L: morning
05:01 AM XXCoder: hey
05:15 AM jthornton: going to be a nice day here today 57°F and sunny
05:16 AM XXCoder: nice
05:19 AM veek: what's a better option: circular saw+table or v-belt+2HPmotor+sawBlade+table (motor is more expensive and lower rpm) circular saw's cheaper and 5200RPM
05:20 AM veek: currently i'm just going to use it as a wood chipper for the garden, eventually as a proper table saw
05:22 AM veek: 2HP 4 Pole Single Phase Foot Mounted Induction Motor 1500RPM :(
05:22 AM veek: but it looks solidly robust
05:22 AM veek: vs circular saw bosch 1100 W so slightly underpowered
05:25 AM jthornton: how does one use a circular saw as a chipper?
05:26 AM veek: you just chip it slowly
05:26 AM veek: till you can build a nice one
05:28 AM jthornton: dang gotta watch the clock a mixed up hen has been laying from the roost and gotta check before the lights come on at 5:32am
05:28 AM veek: i'm not sure about these W ratings on the circular saws.. 2000W is 2.6HP and it's handheld but.. a 2.5HP motor is heavy with 4 poles possibly 3phase
05:29 AM jthornton: ah the old power ratings for saws and vacuums are "peak" power or the surge amps lol
05:30 AM veek: oh hmm!
06:05 AM weenerdog: howdeh
06:09 AM veek: die! weenerdog - die!
06:10 AM * weenerdog plays dead
06:14 AM fragalot: welp. my pond has been cleared out
06:29 AM jthornton: someone stole your water?
06:30 AM XXCoder: or fishies?
06:30 AM XXCoder: or entire pond?
06:41 AM fragalot: the fish are gone
06:42 AM XXCoder: someone actually stole fishes?
06:42 AM gregcnc: what do you fill it with now?
06:46 AM XXCoder: https://www.youtube.com/watch?v=X9XNkJLP1oA
06:47 AM XXCoder: interesting way of bolting rail on and ensuring its stright
06:47 AM XXCoder: 12:30 or so
06:49 AM gregcnc: well it will only be as straight as the extrusion, but the indicator on the trucks is standard practice
06:49 AM XXCoder: thats what he did on other side
06:50 AM XXCoder: oh wait trucks?
06:53 AM XXCoder: what is trucks? did you mean tracks?
06:53 AM gregcnc: for setting parallel on the second rail, an indicator is mounted on trucks on the first properly aligned rail
06:54 AM XXCoder: he mounted an indictor on rail block and touched it on other rail
06:54 AM gregcnc: truck/ slide/rail block
06:56 AM XXCoder: cool
06:56 AM gregcnc: yes that was done correctly
06:57 AM XXCoder: ow! he bent screw
06:57 AM XXCoder: and discovered that his pre-upgrade had same issue
06:59 AM XXCoder: npt sure if his solution would wotrk
06:59 AM gregcnc: but the first rail will only be so straight/flat, and the twist and other issues clearly are a result of building on extrusion
06:59 AM XXCoder: isnt securing it like that at both ends mean its overconstrained?
07:01 AM gregcnc: well dont' crash into endstops. but machine design isn't easy
07:01 AM gregcnc: some screws are under tension
07:01 AM XXCoder: my machibe has no switches I have some but not sure how to attach em
07:02 AM XXCoder: I want proper cnc machine
07:02 AM XXCoder: which means no crashing into sensor
07:02 AM gregcnc: he's going to have terrible whipping issues with that screw
07:02 AM XXCoder: just pass though trigger before some parts fly
07:02 AM gregcnc: the screw is too small
07:03 AM XXCoder: looks like he does wood and plastic only
07:03 AM XXCoder: dunno
07:03 AM gregcnc: screw whipping will limit rapids, at least
07:04 AM XXCoder: makes sense I guess
07:04 AM XXCoder: high speed moving too small screw too big weight causes whipping?
07:04 AM XXCoder: would that permently bend screw?
07:04 AM gregcnc: critical shaft speed
07:05 AM gregcnc: buckling loads will only add to the problem
07:06 AM XXCoder: my useless ballscrews is thicker than his
07:06 AM XXCoder: even the Z one thats bit less than foor less
07:06 AM XXCoder: *long
07:06 AM XXCoder: I dont know what im going to do with those sbrs and ballscrews.
07:09 AM gregcnc: what's wrong with these parts?
07:09 AM XXCoder: oh nothing wrong
07:09 AM XXCoder: just derailed plans
07:09 AM gregcnc: oh
07:09 AM XXCoder: I planned to make crappy wood cnc with it
07:09 AM XXCoder: then make MDF then alum
07:09 AM gregcnc: I have 6 foot rails and screw sitting for years
07:10 AM XXCoder: basically a cnc machine to make parts for better version of itself
07:10 AM XXCoder: wood cnc would be really bad idea to use otherwise.
07:10 AM gregcnc: was considering selling, but now I'll have the room to do something with them
07:10 AM XXCoder: im not sure how to sell em
07:11 AM gregcnc: lol ups tag is dated '06
07:11 AM XXCoder: threw box away unfortunately. I think I bought sbrs and screws in 2014 something?
07:12 AM XXCoder: https://www.youtube.com/watch?v=2rk7DJ6p-nQ fun
07:12 AM gregcnc: if you plan on working on things, it's probably not a huge investment keep them.
07:12 AM XXCoder: those is also total crap
07:13 AM XXCoder: video is kinda out of date, we can get shitty extrusion version for 1/4 the price
07:13 AM XXCoder: shitty but still way better
07:13 AM gregcnc: lol "for some reason everything feels dirty, covered in fine oily grit"
07:14 AM XXCoder: just wait the oily finale joke is amazing
07:14 AM fragalot: syyl: congrats on the biax.
07:21 AM XXCoder: "overcomplicated printer" not really
07:21 AM XXCoder: even shitty inkjet is super complex compared with cnc router
07:36 AM XXCoder: jthornton: first facebook think im about to lose a house, with lots of apartment ads
07:36 AM XXCoder: now they think im rich. its adversing 800k house.
07:41 AM jthornton: facebook is crap
07:42 AM XXCoder: its only way for me to talk with some people as well as some news
07:42 AM XXCoder: before you ask, yes, lots crap also
07:43 AM XXCoder: just apply some critical thinking, meaning dont simply agree or disagree based on feeling or how well it matches viewpoint
07:58 AM jdh: you just ruled out 80%
08:21 AM sensille: Loetmichel: so to test i just drilled a hole, came out 2.05mm (2mm endmill) with the tool insert quite much, and 2.2mm with the tool sticking out more
08:26 AM weenerdog: bent tool or bad chuck?
08:27 AM weenerdog: is it 2.2mm round or ellipsoid?
08:27 AM sensille: i don't know, the tool is quite new and rolls nicely over a flat surface
08:27 AM gregcnc: bent is unlikely
08:27 AM sensille: good question
08:27 AM gregcnc: runout in the collet is probable
08:27 AM weenerdog: then it aint the tool. did you square your spindle?
08:27 AM sensille: yes
08:28 AM sensille: i also feel the tool slightly vibrating
08:28 AM sensille: but have no reference for 'slight'
08:29 AM sensille: i could try the other collet
08:34 AM sensille: can i mount the tool misoriented or is the collet supposed to always correct it? i'd expect the latter...
08:34 AM gregcnc: Collets should run true, but only as well as the are made, and the spindle taper allows
08:35 AM gloops: it is possible to trap the collet out of true in the cheapo er stems
08:35 AM gregcnc: an assuming things are clean
08:35 AM gregcnc: gloops how?
08:35 AM gloops: make sure the collet is clicked in properly
08:36 AM gloops: gregcnc ive not thought it through tbh, but the odd time i have started nipping a tool up and noticed something doesnt feel right, when you spin the spindle the tool is looking well out
08:37 AM gregcnc: ER?
08:37 AM gloops: yes
08:37 AM gregcnc: and it's not chips in the collet/nut/taper?
08:37 AM sensille: my expectation would be that i could mess it up completely, or not a all, but not just slightly
08:38 AM gregcnc: slightly is related to tolerances in the spindle, taper, and collet
08:39 AM sensille: i guess i just wait for my dial indicator holder to arrive
08:39 AM gregcnc: even the nut
08:39 AM gloops: possibly, when i have encountered this i find the collet isnt clicked in properly, so maybe some debris, maybe some shortcoming of cheap spring collets, or over hasty fitting, its usually rectified by removing collet, replacing and making sure it clicks in satisfactorily
08:40 AM gloops: sensille that is my experience - completely or not at all
08:42 AM gregcnc: if you indicate tools with a .0001" indicator you'll see
09:03 AM weenerdog: heh 58 for the high today. long range forecast is 8-12in of snow next saturday
09:15 AM sensille: ok, so i just bolted the dial indicator down, removed the nur from the spindle and pointed it at the thread. max deviation ~0.05mm
09:16 AM sensille: next with a tool and measure the shaft
09:18 AM treats: Hey all, I've been working on this little woodworking project where a few pieces get joined together. There are a lot of small gaps, so I designed my CAM in a way to take advantage of a 1/8 bit router through those gaps. I'll have to cut out all the other pieces separately.
09:18 AM treats: The tool workflow for the first piece was adaptive clear with 1/4, adaptive clear with 1/8 (clear the gaps), and contour with the 1/8 bit.
09:19 AM treats: My question, using too many words already, is there an advantage to use a 1/8 contour to finish vs a 1/4?
09:20 AM treats: I'd prefer to use 1/4 and just waste a little extra wood, but if I can get more accurate with the 1/8 I'll do that, I'm just not sure if I'm gaining or losing precision...
09:23 AM Tom_L: 1/8 will get into any corners better if there's any material left there
09:24 AM Tom_L: the accuracy is in the machine and methods
09:24 AM sensille: *phew* measure at the shaft directly below the collet it's <0.01mm
09:26 AM gregcnc: check the taper where the collet fits
09:29 AM sensille: from inside? can't reach that with my current setup
09:30 AM gregcnc: OK, that's the part that matters. But you can check your tools once installed with what you have.
09:31 AM sensille: and only the shaft of the tool, the indicator only has a rounded tip
09:31 AM gregcnc: you can check flutes with that
09:35 AM sensille: just compare the 2 flutes?
09:36 AM Tom_L: turn it backward when you do
09:48 AM sensille: on a 6mm 2-flute both differ by >0.3mm :( might still be a bad tool, chinese stock tool
09:49 AM sensille: (and if i hadn't just misplaced the small collet i could check the better quality tools)
09:49 AM gregcnc: that would be terrible for a tool. what kind of spindle is this? and what kind of collets?
09:52 AM sensille: i think the collets are called ER-11, the spindle came with the chinese 6040Z, 800W
09:54 AM gregcnc: you'd want to indicate the taper before worrying much. could be bad collet or nut.
09:55 AM sensille: just mount the indicator at an angle, right?
09:55 AM gregcnc: ideally a test indicator so you can check further up the taper also
09:59 AM sensille: next instrument to order :)
09:59 AM sensille: ok, so other collet, 3mm carbide 2-flute: diff 0.001mm
09:59 AM sensille: so very inconsistent
10:03 AM Loetmichel: sensille: the 0.2mm are likely ellipsoid
10:03 AM Loetmichel: try to measure the hole in x and y
10:04 AM Loetmichel: if its only in y 2.2 and in x spot on then its likely the gantry bending from the plunge forces
10:04 AM sensille: they aren't
10:04 AM Loetmichel: if its 2.2 all around it could be runout or dirt in the collet
10:04 AM sensille: et voila, with the current tool the hole is only 0.00-0.05mm off
10:05 AM sensille: Loetmichel: can runout be corrected on that spindle?
10:05 AM Loetmichel: yes
10:05 AM Loetmichel: but its dirty work
10:05 AM Loetmichel: and you need a proxxon/dremel and a grinding stone on it
10:06 AM sensille: "yes" already lets me rest a bit :)
10:06 AM sensille: i'll order a test indicator first to measure the taper
10:06 AM sensille: any recommendations?
10:07 AM Loetmichel: for starters i would take a cellphone cam and look into the taper in the spindle
10:07 AM Loetmichel: is it rough or smooth? do you see debris inside the tape?
10:07 AM Loetmichel: taper
10:07 AM Loetmichel: and is the collet good or cheap crap?
10:08 AM sensille: ah, yes, cellphone cam, i'm getting old, too :P
10:08 AM Loetmichel: you can also paint the collet with some "edding" on the outside, insert it into the spindle without the nut and turn it
10:09 AM Loetmichel: and see if it "carries" on the whole taper or just on a spot (see where the edding disappears)
10:09 AM sensille: you know the collets, how can they be something else that cheap crap?
10:09 AM sensille: i'll start with the edding test
10:09 AM Loetmichel: the ones i have are good, despite being cheap chinese ones from ebay
10:10 AM Loetmichel: but thats the crux with cheap products: they cheap out on quality chechs first
10:10 AM Loetmichel: so you may get good ones or not.
10:11 AM Loetmichel: americans would call that a "sharpie" test i think ;)
10:11 AM sensille: they don't look like crap on first sight, but i don't know what to look for
10:11 AM sensille: ah, i have something better than a smartphone cam, a usb "microscope"
10:18 AM sensille: Loetmichel: hm, doesn't tell me much: https://i.imgur.com/cyUrwhB.jpg
10:24 AM sensille: i'd say the edding disappears reasonably equally
10:26 AM gregcnc: you want to look at the walls not the bottom of the hole
10:32 AM sensille: i thought i had, bad perspective :( much more conclusive: https://i.imgur.com/59vaUXE.mp4
10:35 AM sensille: and when running: https://i.imgur.com/FMy3osb.mp4
10:36 AM sensille: the rim is steady
10:46 AM Loetmichel: sensille: the bottom is not important
10:46 AM Loetmichel: look at the taper on the inside
10:46 AM sensille: see the other 2 videos
10:47 AM Loetmichel: if the edding disappears on the whole taper of the collet its reasonably close to be the right taper
10:47 AM Loetmichel: thats good
10:48 AM sensille: especially the last video doesn't look like runout to be, but i can't say if the resolution is good enough to tell
10:48 AM Loetmichel: you cant see runout there
10:48 AM Loetmichel: i mean: you could, but if you can see it there its whole mm not thousands
10:48 AM Loetmichel: :-)
10:49 AM Loetmichel: but the surface of the taper looks somewhat reasonable
10:49 AM Loetmichel: maybe take a cotton ball and a wooden stick and make yourself a monster "q-tip" to get any dirt out of there
10:50 AM Loetmichel: any swarf/debris in between the collet and the taper in the spindle will cause runout
10:50 AM sensille: that's 5mm on 640 pixel
10:50 AM Loetmichel: also: those collets are only meant for 0.5mm "closing"
10:51 AM Loetmichel: so dont use a to small or to large collet for your tools
10:51 AM Loetmichel: do you have a full set of collets or only 3,175 and 6mm?
10:51 AM sensille: only the 2 that came with it
10:51 AM Loetmichel: so 1/8" and 6mm?
10:51 AM Loetmichel: and what are your tool shank diameters?
10:52 AM sensille: i just assumed it to be 3,175 without thinking twice. the sorotec 2-flute 2mm
10:56 AM sensille: but that looks correct
10:58 AM sensille: a runout of 0.05mm should be slightly visible in the video, but i'll get a dial test indicator, i'm sure that's not the only purpose i'll have for it
10:58 AM sensille: and maybe get some additional collets
11:39 AM karlheinz: test
11:42 AM JT-Shop: fail
11:46 AM sensille: gregcnc: what resolution should i get for the test indicator?
11:47 AM Tom_L: how accurate do you want to measure?
11:48 AM JT-Shop: accuracy and resolution are not the same thing :)
11:49 AM Tom_L: they somewhat go hand in hand
11:49 AM sensille: choices are 0.01mm or 0.002mm, basically same price, different range
11:50 AM JT-Shop: hmm my mitutoyo calipers have 0.0001 resolution but are not accurate to that
11:52 AM sensille: to measure runout 0.01mm might not be enough, even on that cheap machine, not sure
12:07 PM rmu: i think accuracy isn't that critical for measuring runout, it doesn't help if you know your runout it 0,00955 +- 5nm; to tap something in the indicator needs to be repeatable and have high enough resolution, but it doesn't really matter that much if the scale is in imperial, metric or something in between and is non-linear
12:08 PM sensille: rmu: would you think 0.01mm is enough resolution for my chinese spindle?
12:17 PM rmu: resolution of the scale?
12:17 PM rmu: probably yes
12:18 PM rmu: i have a 1/100 indicator that has one rotation per mm, so 1/100mm equals 3.6°, you can easly read it to 5/1000 or better
12:19 PM rmu: for my purposes that's good enough
12:19 PM rmu: what do you want to do with the runout measurement?
12:20 PM sensille: at first: see if it's a problem
12:20 PM sensille: and if it is: hope loetmichel explains to me how to fix it (he calls it "some dirty work")
12:22 PM rmu: you can loosen the collect somewhat and lightly tap the tool to compensate for some runout
12:23 PM rmu: (then tighten and check again)
12:24 PM rmu: but i'm just an informed laymen, no expert
12:33 PM Loetmichel: rmu: same here
12:34 PM Loetmichel: usually its enought with those spindles to turn the tool in the collet a few times and retighten the collet
12:34 PM Loetmichel: measure, if still to much runout, losen the collet nut, turn the tool/colled, refix
12:35 PM Loetmichel: but the better solution is to get a collet thats good (sorotec.de has good quality ER11 iirc) and then grind the taper in the spindle to fit that.
12:35 PM Loetmichel: which is pretty easy, can even be done on the CNC mill
12:36 PM Loetmichel: just have to have a grinder and a small stone and a way to fix the spindle on the Z axis with the right angle so the collet taper is plum to the table
12:37 PM Loetmichel: then you can turn the spindle slowly (few 100 rpm) and plunge in z with a dremel with grinding stone at full RPM...
12:37 PM Loetmichel: redo until no more sparks and better fit for the collet
12:40 PM Loetmichel: IIRC you have to tilt the spindle exactly 8° to match the collet taper
12:49 PM sensille: 26 euro each, hm
12:50 PM sensille: ah, no, that's the 'praezision' series
12:53 PM sensille: so around 8 euro, i'll try that
01:40 PM Loetmichel: *MUHAHA* keith fenner video repairing a bit hydraulic ram... *proceeds to smack a big allen wrench in the cap bolts with a rawhide mallet.... "so now that those bolts are torqued in...."
01:53 PM Loetmichel: ... i thing he even said "properly torqued in" :)
02:23 PM fragalot: Loetmichel: calibrated hammer. if it's good enough to do a hardness test, it's good enough for Keith. :-)
02:26 PM Loetmichel: :-)
03:09 PM gloops: damn, there are just times when i want to watch Ichs videos and hear him say 'fireworks' again
03:46 PM Deejay: gn8
06:57 PM XXCoder: jdh: precisely.
07:29 PM weenerdog: howdy
07:30 PM XXCoder: hey
07:30 PM weenerdog: hey man
07:31 PM XXCoder: whats up
07:33 PM weenerdog: nada. chillin
07:33 PM XXCoder: same
07:33 PM weenerdog: gf went home. watching sw tutorial viddys
07:33 PM XXCoder: i expected wiiu to arrive yeserday but nope
07:33 PM XXCoder: so nbothing to do
07:34 PM weenerdog: whats a wiiu?
07:34 PM XXCoder: what software?
07:34 PM XXCoder: wii u game console
07:34 PM weenerdog: ahhh
07:34 PM weenerdog: solidwerks
07:34 PM weenerdog: solid"works" lol
07:34 PM XXCoder: ahh cool. too expensive for me
07:35 PM weenerdog: i can get a veterans license for $20
07:35 PM XXCoder: wow nice
07:40 PM XXCoder: i played with freecad cam a bit
07:40 PM XXCoder: seemed workable though not very refined yet
07:40 PM XXCoder: hard part is feeds and rpm figuring as I suck on those.
08:15 PM jbart: Am setting up a <scale> control. Need to find the halpin that controls jog speed. where is the best place to look?
08:15 PM XXCoder: hey
08:15 PM XXCoder: yeah should be in docs
08:16 PM jbart: OK, I'll look. Tks.
08:16 PM XXCoder: hmm maybe http://linuxcnc.org/docs/html/gui/pyvcp-examples.html ?
08:16 PM XXCoder: its fir gui
08:17 PM jbart: Ok. I have it in .pdf and can look there. Thought maybe there was a place in linuxcnc where I could find it in order to get exact nomenclature.
08:18 PM XXCoder: yeah unfortunately its not area I really know. I know mainly in vismach area
08:19 PM MarcelineVQ: there's some place in axis you can see all currently available pins, can't remember what it's called currently
08:19 PM XXCoder: hmm hold on a second
08:20 PM MarcelineVQ: there's two places I think, one that pops up a menu called hal configuration, and one that pops up just pins
08:20 PM XXCoder: halshow
08:20 PM jbart: I'm a block from the shop and we have 8" snow and cold so am trying to avoid the walk tonight. No worries, if I don't find in docs I'll get tomorrow. Rgds.
08:21 PM XXCoder: halmeter is one that is simpler to browse
08:21 PM XXCoder: halshow is grouped if you know what youre looking for
08:21 PM XXCoder: had to figure those out when I was making rolfmill
08:23 PM XXCoder: https://www.youtube.com/watch?v=eLdlV3-JaH8 lol
08:24 PM XXCoder: his steppers for etch cnc is bigger than my cnc router ones
08:24 PM XXCoder: im pretty sure I'll have to upgrade mine evenually it might be too small for my cnc router
08:24 PM XXCoder: as small as it is.
08:26 PM MarcelineVQ: He also smartly got the double-ended shafts, for optional encoding :>
08:26 PM XXCoder: indeed
08:26 PM XXCoder: I want encoders but way overkill for small machine
08:26 PM MarcelineVQ: Though, it makes more sense to encode the things in the chain closer to the tool, to minimize the backlash he was tlaking about
08:27 PM MarcelineVQ: Like, if I've you've got 4 worm-reducers you'd probably want to encode the output for accuracy, not the input
08:28 PM XXCoder: 4 worm reducers? would universe end before machine reaches other end? ;)
08:29 PM MarcelineVQ: Sometimes mountains need to move XXCoder, it's faster than erosion at least
08:29 PM XXCoder: lol
08:30 PM XXCoder: theres one artwork that has massive gearing
08:30 PM XXCoder: the input is slowly rotating, and end gear is enclosed in concerete
08:30 PM XXCoder: it wont break for very long time
08:30 PM MarcelineVQ: gears are primally satisfying for some reason
08:31 PM XXCoder: https://www.exploratorium.edu/exhibits/machine-with-concrete
08:32 PM XXCoder: https://www.youtube.com/watch?v=kb4J_uGdo9I
08:32 PM XXCoder: you can see that first one is spinning away
08:32 PM XXCoder: you could see maybe 1/6 of gears is visiably moving
08:32 PM MarcelineVQ: there's a few 3d-printed gear videos that replicate this idea, though those ones tend to warm up on the input and melt :>
08:35 PM XXCoder: i bet
08:43 PM XXCoder: excellent example on backlash
08:44 PM MarcelineVQ: yeah he's a smart cookie. it's too bad he's got like, videos or edit, and kids/famaily, and a job and projects and all that, otherwise he'd have time to use linuxcnc hehe :>
08:44 PM MarcelineVQ: *to edit
08:44 PM XXCoder: indeed
08:45 PM gregcnc: why is the kerosene i just pumped green?
08:45 PM MarcelineVQ: is it dyed for farm use?
08:45 PM XXCoder: mold
08:46 PM XXCoder: heh
08:46 PM XXCoder: dunno
08:46 PM gregcnc: red is farm
08:46 PM MarcelineVQ: ah k didn't know if that varied by area
08:46 PM gregcnc: i think it's diesel
08:46 PM MarcelineVQ: seems like a reasonable conclusion
08:46 PM gregcnc: doesn't have nearly as strong a scent
09:00 PM _unreal_: can beat this... got 4 4988 drivers, with an arduino CNC HAT and an arduino and an arduino for $14 cyber monday :)
09:00 PM _unreal_: cant
09:00 PM XXCoder: not bad'
09:00 PM XXCoder: make a cnc etch n sketch
09:00 PM _unreal_: https://www.amazon.com/gp/product/B06XHKSVTG/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
09:01 PM _unreal_: see if you can get a lighting deal
09:01 PM XXCoder: 18 bucks
09:03 PM XXCoder: kuman uno is arudino?
09:04 PM XXCoder: oh its not
09:05 PM XXCoder: though its interesting ill just use parts off my ex-3d printer
09:05 PM XXCoder: it may have been really a shitty printer, but it can do other stuff pretty good I think.
09:05 PM XXCoder: just need to modify it remove bunch 3d printer craop
09:09 PM XXCoder: lol 16 gb is cheaper than 8 gb sdcard
09:09 PM XXCoder: 12 bucks for 8 gb, 16 gb 7 bucks
09:09 PM XXCoder: https://www.amazon.com/Sandisk-Ultra-128GB-Micro-Adapter/dp/B073K14CVB/
09:10 PM _unreal_: hum
09:12 PM _unreal_: 128gb sd cards for $20 good lord
09:12 PM XXCoder: yeah
09:12 PM XXCoder: im considering 7 dollar one becaue I want small sdcard for my retromini custom game packs
09:12 PM XXCoder: dont need much space at all
09:15 PM weenerdog: https://www.youtube.com/watch?v=jjdXpp77MdU <- i dont know if thats awesome or scary. DIN rails as linear motion slides
09:16 PM weenerdog: cheapo fer sure, but gawd
09:16 PM XXCoder: definitely budget. dont do metal
09:17 PM XXCoder: but wood and plastics? sure! just dont push
09:17 PM XXCoder: lol he didnt even bother to ensure that other side rail is parallel with first rail
09:17 PM XXCoder: but same time this is very imprecise machine it wont change much
09:18 PM weenerdog: honeybadger canadian
09:19 PM XXCoder: he uses shit mach3
09:19 PM weenerdog: i wonder what it'll hold.
09:19 PM MarcelineVQ: hmm, lots of z height for that construction
09:19 PM weenerdog: yeah i noticed that marc
09:19 PM MarcelineVQ: good thing it's cutting mdf
09:19 PM XXCoder: yeah it cant do much sideload at all
09:19 PM XXCoder: probably shouldnt be making acual chips just powder
09:19 PM XXCoder: bad for tools but good for machine like that
09:26 PM weenerdog: "hi i'm todd the canadian. i spent more on my drag chain than my rails"
09:26 PM XXCoder: lol
09:27 PM weenerdog: i was kinda feeling it, just for pure rednecking it at all costs until the belt drive
09:28 PM weenerdog: at least regular threaded rod would have a pair of balls
09:28 PM weenerdog: and he obviously aint gonna hold tight tolerances anyhoo
09:29 PM weenerdog: he's like clint eastwood with that air nailer
09:29 PM XXCoder: well some stuff can be comped for
09:29 PM XXCoder: but yeah
09:29 PM XXCoder: depends on what tol needs are on production
09:30 PM MarcelineVQ: your steppers are going to skip before your belt does.
09:31 PM MarcelineVQ: looks like he used a screw underneath, does he explain why he uses a belt elsewhere?
09:31 PM XXCoder: my belt?
09:31 PM MarcelineVQ: no the vid
09:31 PM XXCoder: oh
09:32 PM ziper: why does he say zed
09:32 PM weenerdog: because he's canadian
09:32 PM MarcelineVQ: That's how its pronounced :>
09:33 PM MarcelineVQ: some time ago some queen thought that was pretty cool way to say it and it stuck with some people
09:34 PM weenerdog: they only do it when americans are listening
09:34 PM XXCoder: canadian eh
09:34 PM MarcelineVQ: I call it a zee axis because that's the name of the axis
09:34 PM MarcelineVQ: zed is the name of some letter :>
09:35 PM ziper: aaaa he has the same power supply i got except his inductor is probably attached to the pcb
09:40 PM weenerdog: i like his dust collection head. i might (sort of) steal that idea
09:44 PM XXCoder: i plan to 3d print dust seperator for mine
09:44 PM XXCoder: theres fanastic object in thingverse lemme link it
09:46 PM XXCoder: https://www.thingiverse.com/thing:1447214
09:49 PM MarcelineVQ: every day I'm more convinced I should have a 3d printer, once you're dialed in being able to just 'order-up' that kind of functional thing is pretty great
09:50 PM XXCoder: buy chinese shit ones only if youre very very good on fixing mechinial problems
09:51 PM MarcelineVQ: I expect the hardest part is finding a quality printing head, in function and design
09:52 PM XXCoder: heh not too sure, extruder and hotend definitely hardest for me
09:52 PM XXCoder: but then mine was very cheao
09:56 PM MarcelineVQ: You happy with it?
09:56 PM XXCoder: no lol
09:57 PM XXCoder: its a ex-printer now
09:57 PM XXCoder: I plan to adopt it to something else like laser or pen draw
09:58 PM MarcelineVQ: hehe
09:58 PM MarcelineVQ: pen draw is kind of neat for etching
10:11 PM XXCoder: yeah
11:46 PM XXCoder: wow
11:46 PM XXCoder: 29f nights at wed and thurs
11:46 PM XXCoder: if it actually hapoens then its pretty rare event here
11:47 PM XXCoder: probably because its clear 4 days in row
