[05:47:18] <jthornton> morning
[05:47:28] <XXCoder> hey
[06:00:04] <Tom_L> morning
[06:00:15] <XXCoder> hey
[06:13:35] <jthornton> going to be a nice day here today 57°F and sunny
[06:14:21] -!- veek has joined #linuxcnc
[06:14:32] <XXCoder> nice
[06:17:32] -!- arekm has quit [Quit: leaving]
[06:17:40] <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
[06:17:42] -!- arekm has joined #linuxcnc
[06:18:16] <veek> currently i'm just going to use it as a wood chipper for the garden, eventually as a proper table saw
[06:20:18] <veek> 2HP 4 Pole Single Phase Foot Mounted Induction Motor 1500RPM :(
[06:20:31] <veek> but it looks solidly robust
[06:21:11] <veek> vs circular saw bosch 1100 W so slightly underpowered
[06:23:41] <jthornton> how does one use a circular saw as a chipper?
[06:24:20] <veek> you just chip it slowly
[06:24:39] <veek> till you can build a nice one
[06:26:39] <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
[06:26:41] <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
[06:27:28] <jthornton> ah the old power ratings for saws and vacuums are "peak" power or the surge amps lol
[06:28:31] <veek> oh hmm!

[07:09:08] * weenerdog plays dead
[07:13:06] <fragalot> welp. my pond has been cleared out
[07:27:41] <jthornton> someone stole your water?
[07:28:57] <XXCoder> or fishies?
[07:29:07] <XXCoder> or entire pond?
[07:40:04] <fragalot> the fish are gone
[07:40:18] <XXCoder> someone actually stole fishes?
[07:40:29] <gregcnc> what do you fill it with now?
[07:45:08] <XXCoder> https://www.youtube.com
[07:45:18] <XXCoder> interesting way of bolting rail on and ensuring its stright
[07:45:25] <XXCoder> 12:30 or so
[07:47:53] <gregcnc> well it will only be as straight as the extrusion, but the indicator on the trucks is standard practice
[07:48:15] <XXCoder> thats what he did on other side
[07:48:40] <XXCoder> oh wait trucks?
[07:51:19] <XXCoder> what is trucks? did you mean tracks?
[07:51:46] <gregcnc> for setting parallel on the second rail, an indicator is mounted on trucks on the first properly aligned rail
[07:52:24] <XXCoder> he mounted an indictor on rail block and touched it on other rail
[07:53:08] <gregcnc> truck/ slide/rail block
[07:54:20] <XXCoder> cool
[07:54:28] <gregcnc> yes that was done correctly
[07:55:38] <XXCoder> ow! he bent screw
[07:55:51] <XXCoder> and discovered that his pre-upgrade had same issue
[07:57:23] <XXCoder> npt sure if his solution would wotrk
[07:57:25] <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
[07:57:40] <XXCoder> isnt securing it like that at both ends mean its overconstrained?
[07:59:37] <gregcnc> well dont' crash into endstops. but machine design isn't easy
[07:59:58] <gregcnc> some screws are under tension
[08:00:12] <XXCoder> my machibe has no switches I have some but not sure how to attach em
[08:00:21] <XXCoder> I want proper cnc machine
[08:00:28] <XXCoder> which means no crashing into sensor
[08:00:42] <gregcnc> he's going to have terrible whipping issues with that screw
[08:00:43] <XXCoder> just pass though trigger before some parts fly
[08:01:07] <gregcnc> the screw is too small
[08:01:23] <XXCoder> looks like he does wood and plastic only
[08:01:27] <XXCoder> dunno
[08:02:05] <gregcnc> screw whipping will limit rapids, at least
[08:02:24] <XXCoder> makes sense I guess
[08:02:49] <XXCoder> high speed moving too small screw too big weight causes whipping?
[08:02:56] <XXCoder> would that permently bend screw?
[08:03:04] <gregcnc> critical shaft speed
[08:03:52] <gregcnc> buckling loads will only add to the problem
[08:04:31] <XXCoder> my useless ballscrews is thicker than his
[08:04:44] <XXCoder> even the Z one thats bit less than foor less
[08:04:46] <XXCoder> *long
[08:05:03] <XXCoder> I dont know what im going to do with those sbrs and ballscrews.
[08:07:18] <gregcnc> what's wrong with these parts?
[08:07:26] <XXCoder> oh nothing wrong
[08:07:31] <XXCoder> just derailed plans
[08:07:39] <gregcnc> oh
[08:07:41] <XXCoder> I planned to make crappy wood cnc with it
[08:07:54] <XXCoder> then make MDF then alum
[08:07:57] <gregcnc> I have 6 foot rails and screw sitting for years
[08:08:16] <XXCoder> basically a cnc machine to make parts for better version of itself
[08:08:30] <XXCoder> wood cnc would be really bad idea to use otherwise.
[08:08:52] <gregcnc> was considering selling, but now I'll have the room to do something with them
[08:09:07] <XXCoder> im not sure how to sell em
[08:09:39] <gregcnc> lol ups tag is dated '06
[08:10:06] <XXCoder> threw box away unfortunately. I think I bought sbrs and screws in 2014 something?
[08:11:01] <XXCoder> https://www.youtube.com fun
[08:11:03] <gregcnc> if you plan on working on things, it's probably not a huge investment keep them.
[08:11:06] <XXCoder> those is also total crap
[08:11:37] <XXCoder> video is kinda out of date, we can get shitty extrusion version for 1/4 the price
[08:11:43] <XXCoder> shitty but still way better
[08:12:08] <gregcnc> lol "for some reason everything feels dirty, covered in fine oily grit"
[08:12:25] <XXCoder> just wait the oily finale joke is amazing
[08:12:46] <fragalot> syyl: congrats on the biax.
[08:19:40] <XXCoder> "overcomplicated printer" not really
[08:19:55] <XXCoder> even shitty inkjet is super complex compared with cnc router

[09:07:15] -!- CubicleNate has quit [Ping timeout: 246 seconds]
[09:20:02] <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
[09:20:14] -!- syyl_ has joined #linuxcnc
[09:23:12] -!- syyl has quit [Ping timeout: 268 seconds]
[09:24:34] <weenerdog> bent tool or bad chuck?
[09:25:21] <weenerdog> is it 2.2mm round or ellipsoid?
[09:25:23] <sensille> i don't know, the tool is quite new and rolls nicely over a flat surface
[09:25:36] <gregcnc> bent is unlikely
[09:25:39] <sensille> good question
[09:25:51] <gregcnc> runout in the collet is probable
[09:25:53] <weenerdog> then it aint the tool. did you square your spindle?
[09:26:06] <sensille> yes
[09:26:19] <sensille> i also feel the tool slightly vibrating
[09:26:35] <sensille> but have no reference for 'slight'
[09:28:04] <sensille> i could try the other collet
[09:34:30] -!- gloops has joined #linuxcnc
[09:34:30] <sensille> can i mount the tool misoriented or is the collet supposed to always correct it? i'd expect the latter...
[09:34:30] <gregcnc> Collets should run true, but only as well as the are made, and the spindle taper allows
[09:34:30] <gloops> it is possible to trap the collet out of true in the cheapo er stems
[09:34:30] <gregcnc> an assuming things are clean
[09:34:30] <gregcnc> gloops how?
[09:34:30] <gloops> make sure the collet is clicked in properly
[09:34:30] -!- logs has quit [Ping timeout: 252 seconds]
[09:35:41] -!- logs has joined #linuxcnc
[09:36:00] <gregcnc> and it's not chips in the collet/nut/taper?
[09:36:08] <sensille> my expectation would be that i could mess it up completely, or not a all, but not just slightly
[09:36:50] <gregcnc> slightly is related to tolerances in the spindle, taper, and collet
[09:37:31] <sensille> i guess i just wait for my dial indicator holder to arrive
[09:37:34] <gregcnc> even the nut
[09:38:05] <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

[09:39:35] -!- tumdedum has joined #linuxcnc
[09:40:20] <gregcnc> if you indicate tools with a .0001" indicator you'll see

[10:12:05] -!- KimK has quit [Quit: Leaving]
[10:14:11] <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
[10:14:38] <sensille> next with a tool and measure the shaft
[10:14:39] -!- treats has joined #linuxcnc
[10:16:30] <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.
[10:16:56] -!- ferdna has joined #linuxcnc
[10:17:03] <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.
[10:17:27] <treats> My question, using too many words already, is there an advantage to use a 1/8 contour to finish vs a 1/4?
[10:18:36] <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...
[10:21:43] <Tom_L> 1/8 will get into any corners better if there's any material left there
[10:22:32] <Tom_L> the accuracy is in the machine and methods
[10:22:59] <sensille> *phew* measure at the shaft directly below the collet it's <0.01mm
[10:24:45] <gregcnc> check the taper where the collet fits
[10:28:07] <sensille> from inside? can't reach that with my current setup
[10:28:47] <gregcnc> OK, that's the part that matters. But you can check your tools once installed with what you have.

[10:29:41] <sensille> and only the shaft of the tool, the indicator only has a rounded tip
[10:30:10] <gregcnc> you can check flutes with that
[10:33:55] <sensille> just compare the 2 flutes?
[10:34:32] <Tom_L> turn it backward when you do

[10:42:42] -!- Roguish has joined #linuxcnc
[10:46:32] <sensille> on a 6mm 2-flute both differ by >0.3mm :( might still be a bad tool, chinese stock tool
[10:47:15] <sensille> (and if i hadn't just misplaced the small collet i could check the better quality tools)
[10:47:44] <gregcnc> that would be terrible for a tool. what kind of spindle is this? and what kind of collets?
[10:50:25] <sensille> i think the collets are called ER-11, the spindle came with the chinese 6040Z, 800W
[10:52:34] <gregcnc> you'd want to indicate the taper before worrying much. could be bad collet or nut.
[10:53:19] <sensille> just mount the indicator at an angle, right?
[10:53:55] <gregcnc> ideally a test indicator so you can check further up the taper also
[10:57:38] <sensille> next instrument to order :)
[10:58:01] <sensille> ok, so other collet, 3mm carbide 2-flute: diff 0.001mm
[10:58:13] <sensille> so very inconsistent
[11:01:32] <Loetmichel> sensille: the 0.2mm are likely ellipsoid
[11:01:45] <Loetmichel> try to measure the hole in x and y
[11:02:19] <Loetmichel> if its only in y 2.2 and in x spot on then its likely the gantry bending from the plunge forces
[11:02:24] <sensille> they aren't
[11:02:33] <Loetmichel> if its 2.2 all around it could be runout or dirt in the collet
[11:02:52] <sensille> et voila, with the current tool the hole is only 0.00-0.05mm off
[11:03:24] <sensille> Loetmichel: can runout be corrected on that spindle?
[11:03:32] <Loetmichel> yes
[11:03:43] <Loetmichel> but its dirty work
[11:03:58] <Loetmichel> and you need a proxxon/dremel and a grinding stone on it
[11:04:23] <sensille> "yes" already lets me rest a bit :)
[11:04:42] <sensille> i'll order a test indicator first to measure the taper
[11:04:59] <sensille> any recommendations?
[11:05:36] <Loetmichel> for starters i would take a cellphone cam and look into the taper in the spindle
[11:05:53] <Loetmichel> is it rough or smooth? do you see debris inside the tape?
[11:05:54] <Loetmichel> taper
[11:06:12] <Loetmichel> and is the collet good or cheap crap?
[11:06:26] <sensille> ah, yes, cellphone cam, i'm getting old, too :P
[11:07:00] <Loetmichel> you can also paint the collet with some "edding" on the outside, insert it into the spindle without the nut and turn it
[11:07:08] -!- gloops has quit [Ping timeout: 245 seconds]
[11:07:27] <Loetmichel> and see if it "carries" on the whole taper or just on a spot (see where the edding disappears)
[11:07:44] <sensille> you know the collets, how can they be something else that cheap crap?
[11:08:08] <sensille> i'll start with the edding test
[11:08:13] <Loetmichel> the ones i have are good, despite being cheap chinese ones from ebay
[11:08:44] <Loetmichel> but thats the crux with cheap products: they cheap out on quality chechs first
[11:08:52] <Loetmichel> so you may get good ones or not.
[11:09:20] <Loetmichel> americans would call that a "sharpie" test i think ;)
[11:09:25] <sensille> they don't look like crap on first sight, but i don't know what to look for
[11:09:53] <sensille> ah, i have something better than a smartphone cam, a usb "microscope"
[11:16:16] <sensille> Loetmichel: hm, doesn't tell me much: https://i.imgur.com
[11:16:36] -!- ve7it has joined #linuxcnc
[11:21:46] -!- ziper has joined #linuxcnc
[11:23:15] <sensille> i'd say the edding disappears reasonably equally
[11:24:29] <gregcnc> you want to look at the walls not the bottom of the hole
[11:31:09] <sensille> i thought i had, bad perspective :( much more conclusive: https://i.imgur.com
[11:34:06] <sensille> and when running: https://i.imgur.com

[11:35:11] <sensille> the rim is steady
[11:44:35] <Loetmichel> sensille: the bottom is not important
[11:44:42] <Loetmichel> look at the taper on the inside
[11:44:57] <sensille> see the other 2 videos
[11:45:20] <Loetmichel> if the edding disappears on the whole taper of the collet its reasonably close to be the right taper
[11:45:21] -!- P1ersson has joined #linuxcnc
[11:45:23] <Loetmichel> thats good
[11:46:18] <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
[11:46:34] <Loetmichel> you cant see runout there
[11:46:58] <Loetmichel> i mean: you could, but if you can see it there its whole mm not thousands
[11:47:01] <Loetmichel> :-)
[11:47:23] <Loetmichel> but the surface of the taper looks somewhat reasonable
[11:47:53] <Loetmichel> maybe take a cotton ball and a wooden stick and make yourself a monster "q-tip" to get any dirt out of there
[11:48:27] <Loetmichel> any swarf/debris in between the collet and the taper in the spindle will cause runout
[11:48:51] <sensille> that's 5mm on 640 pixel
[11:48:52] <Loetmichel> also: those collets are only meant for 0.5mm "closing"
[11:49:22] <Loetmichel> so dont use a to small or to large collet for your tools
[11:49:34] <Loetmichel> do you have a full set of collets or only 3,175 and 6mm?
[11:49:45] <sensille> only the 2 that came with it
[11:49:54] <Loetmichel> so 1/8" and 6mm?
[11:50:10] <Loetmichel> and what are your tool shank diameters?
[11:50:58] <sensille> i just assumed it to be 3,175 without thinking twice. the sorotec 2-flute 2mm
[11:54:31] <sensille> but that looks correct
[11:56:34] <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
[11:57:15] <sensille> and maybe get some additional collets

[12:41:15] <JT-Shop> fail
[12:45:13] <sensille> gregcnc: what resolution should i get for the test indicator?
[12:46:10] <Tom_L> how accurate do you want to measure?
[12:46:57] <JT-Shop> accuracy and resolution are not the same thing :)
[12:47:23] <Tom_L> they somewhat go hand in hand
[12:48:12] <sensille> choices are 0.01mm or 0.002mm, basically same price, different range
[12:48:29] <JT-Shop> hmm my mitutoyo calipers have 0.0001 resolution but are not accurate to that
[12:50:21] <sensille> to measure runout 0.01mm might not be enough, even on that cheap machine, not sure
[13:05:38] <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
[13:06:55] <sensille> rmu: would you think 0.01mm is enough resolution for my chinese spindle?
[13:14:03] -!- gloops has joined #linuxcnc
[13:15:33] <rmu> resolution of the scale?
[13:15:44] <rmu> probably yes
[13:16:53] <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
[13:17:19] <rmu> for my purposes that's good enough
[13:17:49] <rmu> what do you want to do with the runout measurement?
[13:18:40] <sensille> at first: see if it's a problem
[13:19:14] <sensille> and if it is: hope loetmichel explains to me how to fix it (he calls it "some dirty work")
[13:20:47] <rmu> you can loosen the collect somewhat and lightly tap the tool to compensate for some runout
[13:21:27] <rmu> (then tighten and check again)
[13:22:36] <rmu> but i'm just an informed laymen, no expert
[13:30:35] -!- holzjunkie1 has joined #linuxcnc
[13:32:04] <Loetmichel> rmu: same here
[13:32:31] <Loetmichel> usually its enought with those spindles to turn the tool in the collet a few times and retighten the collet
[13:32:58] <Loetmichel> measure, if still to much runout, losen the collet nut, turn the tool/colled, refix
[13:33:52] <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.
[13:34:08] <Loetmichel> which is pretty easy, can even be done on the CNC mill
[13:34:50] <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
[13:35:31] <Loetmichel> then you can turn the spindle slowly (few 100 rpm) and plunge in z with a dremel with grinding stone at full RPM...
[13:35:45] <Loetmichel> redo until no more sparks and better fit for the collet
[13:37:22] -!- holzjunkie1 has quit [Quit: holzjunkie1]
[13:38:25] <Loetmichel> IIRC you have to tilt the spindle exactly 8° to match the collet taper

[21:13:49] <XXCoder> hey
[21:13:53] <XXCoder> yeah should be in docs
[21:14:25] <jbart> OK, I'll look. Tks.
[21:14:33] <XXCoder> hmm maybe http://linuxcnc.org ?
[21:14:41] <XXCoder> its fir gui
[21:14:43] -!- Hank_5136 has quit [Client Quit]
[21:16:15] <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.
[21:16:39] <XXCoder> yeah unfortunately its not area I really know. I know mainly in vismach area
[21:17:33] <MarcelineVQ> there's some place in axis you can see all currently available pins, can't remember what it's called currently
[21:17:45] <XXCoder> hmm hold on a second
[21:18:25] <MarcelineVQ> there's two places I think, one that pops up a menu called hal configuration, and one that pops up just pins
[21:18:58] <XXCoder> halshow
[21:19:01] <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.
[21:19:36] <XXCoder> halmeter is one that is simpler to browse
[21:19:51] <XXCoder> halshow is grouped if you know what youre looking for

[21:22:47] <XXCoder> im pretty sure I'll have to upgrade mine evenually it might be too small for my cnc router
[21:22:51] <XXCoder> as small as it is.
[21:24:27] <MarcelineVQ> He also smartly got the double-ended shafts, for optional encoding :>
[21:24:37] <XXCoder> indeed
[21:24:48] <XXCoder> I want encoders but way overkill for small machine
[21:24:56] <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
[21:26:14] <MarcelineVQ> Like, if I've you've got 4 worm-reducers you'd probably want to encode the output for accuracy, not the input
[21:26:51] <XXCoder> 4 worm reducers? would universe end before machine reaches other end? ;)
[21:27:20] <MarcelineVQ> Sometimes mountains need to move XXCoder, it's faster than erosion at least
[21:27:38] <XXCoder> lol
[21:28:25] <XXCoder> theres one artwork that has massive gearing
[21:28:42] <XXCoder> the input is slowly rotating, and end gear is enclosed in concerete
[21:28:50] <XXCoder> it wont break for very long time
[21:28:57] <MarcelineVQ> gears are primally satisfying for some reason
[21:29:43] <XXCoder> https://www.exploratorium.edu
[21:30:18] <XXCoder> https://www.youtube.com
[21:30:29] <XXCoder> you can see that first one is spinning away
[21:30:48] <XXCoder> you could see maybe 1/6 of gears is visiably moving
[21:30:54] <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 :>
