06:21 AM Tom_L: morning
06:31 AM t4nk_freenode: moaning
06:37 AM t4nk_freenode: not sure what to do man..
06:37 AM t4nk_freenode: I've played around with the beams and carriages
06:37 AM t4nk_freenode: cut the beams for the smaller machine to size
06:38 AM t4nk_freenode: even thought about going for the bigger machine straightaway
06:38 AM t4nk_freenode: cuz I have the smaller one sitting on top of the larger beams
06:38 AM t4nk_freenode: anyhow.. I need to lift the smaller beams up to create some space
06:40 AM t4nk_freenode: and I'm not going to 3d print for this one.
06:40 AM t4nk_freenode: so what I thought was I could cut some of the left over smaller beams up in square blocks
06:41 AM t4nk_freenode: and put two of them underneath a beam on one side
06:41 AM t4nk_freenode: so the beam is 30x30
06:42 AM t4nk_freenode: heh, but that would mean cutting the blocks... and then drill holes, joint them together
06:42 AM Tom_L: bad idea
06:43 AM Tom_L: more places for things to move out of alignment
06:43 AM t4nk_freenode: https://postimg.cc/yJQhNYQM
06:43 AM t4nk_freenode: sort of like this
06:44 AM t4nk_freenode: yeah, I thought about that
06:45 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Z-Riser_blocks.jpg
06:45 AM Tom_L: so far mine are doing ok
06:45 AM Tom_L: but the bottom are welded together
06:46 AM t4nk_freenode: .... that's why I'm also in doubt about buying the welder
06:47 AM t4nk_freenode: are those the 2" beams?
06:51 AM Tom_L: yes
06:51 AM t4nk_freenode: and the rails on that machine are also the same beams, right?
06:56 AM t4nk_freenode: ah, no, I just looked at some of the other pictures
07:01 AM Tom_L: they are all 2"
07:01 AM Tom_L: the riser is 4"
07:02 AM Tom_L: thick wall
07:09 AM AlainPelletierpa: good morning. I am a long time linuxcnc / emc2 user. I am also a blendercam developer. I thought I would pop in here to see what is going on. I have a large 8 x 12 foot Machine with hold down vacuum and a 5hp atc spindle
07:13 AM Tom_L: home built or old iron?
07:14 AM * AlainPelletierpa uploaded a video: (51178KiB) < https://libera.ems.host/_matrix/media/r0/download/matrix.org/BtfqrukiMTExXRciuCoBszOT/20220301_095704_1.mp4 >
07:15 AM AlainPelletierpa: it is a converted machine which had proprietary software
08:13 AM t4nk_freenode: is that you, burping profusely, or is it something else?
08:20 AM t4nk_freenode: well, Tom_L, I'll cut them in a bit.. they'll need to be there, welded or not ;)
08:22 AM AlainPelletierpa: there are some somewhat loose or illfitting metal plates which vibrate at a certain frequency making an odd noise. so no it's not me burping, and the machine is not broken. Besides, wearing ear protection is not optional when operating the spindle, dust collector and hold down at the same time.
08:24 AM t4nk_freenode: ok then, that eases my mind a bit ;)
08:25 AM AlainPelletierpa: I did program kasa outlet on the linuxcnc computer to use M100 and M101 commands to start the dust collector
10:49 AM acer is now known as _unreal_
10:59 AM _unreal_: designing my Z setup now
10:59 AM _unreal_: was going with one direction. but I have changed to a new setup with the total rebuild of this machine
11:09 AM t4nk_freenode: yeah, only one direction isn't very useful ;)
11:09 AM t4nk_freenode: though you could actually say 'can only go up from here'
11:12 AM _unreal_: I'm trying to solve how I want to build my Z lead screw setup
11:13 AM _unreal_: I have lots of spare parts I could use. but I dont like them for this project so far.
11:13 AM _unreal_: I have some bearing shaft devices but they have like 1/32 play in them
11:14 AM _unreal_: when it comes to holding the Z lead screw. I have to have zero
11:14 AM t4nk_freenode: I don't like play.
11:14 AM _unreal_: so... I'm trying to solve building a whole new lead screw setup or using what I have on hand.
11:14 AM _unreal_: and method
11:15 AM t4nk_freenode: what sort of screw have you got?
11:15 AM _unreal_: One means is to stack skate board bearings
11:15 AM _unreal_: I'm using 1/2"-13 TPI
11:15 AM _unreal_: more or less 13mill
11:15 AM t4nk_freenode: so non-trapezoid?
11:16 AM _unreal_: just standard threaded rod
11:16 AM t4nk_freenode: standard threaded rod
11:16 AM _unreal_: its what I use on everything
11:16 AM _unreal_: using that with starboard
11:16 AM _unreal_: starboard, "cutting board" like plastic material
11:16 AM t4nk_freenode: but that's not gonna be very fast, is it?
11:16 AM _unreal_: plenty
11:17 AM _unreal_: I dont need thousands of IPM
11:17 AM _unreal_: I need power
11:17 AM _unreal_: this machine will prob run max........ 500 IPM
11:18 AM _unreal_: 726mm x 533mm is the "working" work bed of this machine
11:18 AM t4nk_freenode: ok, I'll get my kalcilater out; 1270mm/min
11:19 AM _unreal_: ya thats just rapids
11:19 AM _unreal_: tooling speeds typically 26-200mm/min
11:19 AM _unreal_: depends on the material
11:19 AM _unreal_: if I'm milling aluminum my feed rate is below 40 mm/min
11:20 AM _unreal_: this new machine I dont know what feed rate I will be able to work at
11:21 AM _unreal_: bigger motor and faster RPM but its how rigid the framing is and the milling bit in use, and the material, and other factors like "cooling" that I wont have that really affect the overall max feed
11:22 AM _unreal_: even the starboard drive nuts on the threaded rod. they are VERY strong but I have to be carful not to over torque them. Or... I can risk over aggressive wear.
11:22 AM t4nk_freenode: you could/should probably dribble some fluid around by hand
11:22 AM _unreal_: naa
11:22 AM _unreal_: the work bed of the machine is wood
11:22 AM t4nk_freenode: yeah, lol
11:22 AM t4nk_freenode: but still.. I'd do it
11:22 AM _unreal_: the entire base of the machine is wood
11:23 AM _unreal_: its coated with epoxy but
11:23 AM _unreal_: the moment I start making mount systems, I'm cutting into the wood
11:23 AM _unreal_: soo
11:23 AM t4nk_freenode: I may order that welder in a bit
11:24 AM _unreal_: I would then have to seal the hole. and on and on. regardless this type of machine expects to have an MDF waste board
11:24 AM _unreal_: MDF and partical boards do not like water
11:24 AM t4nk_freenode: same on mine
11:25 AM _unreal_: I have no real desire to try and make it setup so I can use a coolant
11:26 AM _unreal_: I am going to try my hand at adding a forced air for clearing chips
11:26 AM _unreal_: I have a nice little pump that I pulled from a food vacuum sealer. good sized too. it has a plastic based try pump.
11:27 AM _unreal_: I've already built a 3d printed air intake filter and mounted it to it. I'm going to setup a PWM speed control as well. I already have a psu that will work for it just fine. simple 12vdc 2amp supply. MORE then enough power
11:28 AM _unreal_: infact seems to run too fast IMO, BUT THEN AGAIN. that pump was being used for vacuum.
11:29 AM _unreal_: so..... I figure if there is no load on it. Its just pushing air at high volume out a small tip. fingers crossed, it should be good for clearing lite chip build up. Mainly its millling into stuff and the chips get packed and stall the milling bit.
11:30 AM t4nk_freenode: (more THAN, not more then... more then is moronic)
11:30 AM _unreal_: I've had that happen so many times milling aluminum. I'm now at a point where I have to stop clear stop clear all the time on my current machine. hate to do it if I'm tooling aluminum, but I dont have a choice. Even up cut bits will not fully clear chips out of a pocket.
11:31 AM _unreal_: and if the chips are really small they really pack and then heat melt and seize the bit. happens all the time. Then the bit heats, looses its temper and wears which heats it more and kills the bit fast.
11:32 AM _unreal_: soo... what is your current build status. you are building something that can really do some tooling right?
11:33 AM _unreal_: now I do have a nice bearing system for my z on the small z machine. It's really easy to setup. problem is the bearings do not last, they are really not designed for the side load setup. so I end up changing them every 400 hours of use.
11:34 AM _unreal_: those bearings are like $4 each and it takes two.
11:36 AM t4nk_freenode: well, I got my beams cut, carriages done
11:36 AM _unreal_: pictures
11:36 AM t4nk_freenode: https://postimg.cc/yJQhNYQM
11:37 AM _unreal_: that works....
11:37 AM _unreal_: beams are aluminum ye?
11:37 AM _unreal_: yes
11:37 AM _unreal_: ?
11:38 AM t4nk_freenode: was gonna cut those little thingies to the left bottom today, but don't feel like it anymore
11:38 AM _unreal_: biggest issue you'll find is wear
11:38 AM t4nk_freenode: do it tomorrow
11:38 AM t4nk_freenode: no, the beams are steel
11:38 AM _unreal_: good
11:38 AM _unreal_: bearings will cut right into aluminum
11:39 AM t4nk_freenode: yeah, I hope this will be better
11:39 AM t4nk_freenode: and there are lots of bearings, so that'll hopefully spread the forces some more
11:39 AM _unreal_: over time they will cut into the steel just NO WERE near as fast
11:40 AM t4nk_freenode: I don't find that steel too hard btw, somehow
11:40 AM t4nk_freenode: I can cut and drill it just fine
11:41 AM Tom_L: any experienced machining graphite?
11:41 AM _unreal_: my pipe is starting to cut some flat spots
11:41 AM _unreal_: not bad but its there
11:42 AM Tom_L: i know it requires spindle speeds 20-40k and a dust evacuation setup but other than that not much
11:42 AM Tom_L: machine dry or it turns to goo
11:43 AM _unreal_: Tom_L, graphite.. no but I would assume you want a rotary rasp
11:43 AM t4nk_freenode: so that's very soft material, right?
11:44 AM Tom_L: very abrasive
11:46 AM Tom_L: and brittle
11:47 AM t4nk_freenode: what's the use gonna be?
11:48 AM Tom_L: graphite parts :)
11:49 AM Tom_L: i'm not going to try, i'm not set up for it
11:49 AM t4nk_freenode: because of the lubrifi-thingy characteristics?
11:50 AM t4nk_freenode: dunno if it's expensive, otherwise I'd just go for it, see what happens ;)
11:50 AM Tom_L: i've cut tungsten but this is different
11:50 AM Tom_L: similar but different
11:51 AM t4nk_freenode: Tom_L, https://www.lidl.nl/p/parkside-vuldraad-lasapparaat/p100342661 I think I might buy this
11:52 AM Tom_L: small
11:52 AM Tom_L: not too bad
11:52 AM t4nk_freenode: price seems very nice
11:53 AM t4nk_freenode: there are some wires included, but I'd also want to buy an extra spool
11:53 AM t4nk_freenode: but I don't know how thick it should be
11:55 AM t4nk_freenode: there's .6, .9 and 1.0mm
12:04 PM Tom_L: i typically use either .025, .030 or .035"
12:04 PM Tom_L: i forget what size my big spool is
12:04 PM Tom_L: probably .035
12:05 PM t4nk_freenode: I'm probably not going to weld anything thicker than 1.5-2mm
12:05 PM Tom_L: you could probably do up to ~5mm maybe
12:05 PM Tom_L: not quite that thick
12:06 PM t4nk_freenode: one comment stated it could do up to 10mm, with a good technique
12:06 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Welding/Miller.jpg
12:06 PM Tom_L: i can do 1/4" pretty easy
12:07 PM Tom_L: 10mm might be pushit it
12:07 PM Tom_L: i haven't tried much more than that since i've had no reason to
12:07 PM t4nk_freenode: so with .025" wire... the weld is just finer, smaller?
12:08 PM t4nk_freenode: less deposit
12:08 PM Tom_L: generally for thinner metals yes
12:08 PM Tom_L: less filler
12:08 PM Tom_L: or feed the heck out of it
12:09 PM Tom_L: does it come with a bottle?
12:09 PM t4nk_freenode: and I'm also assuming this form of welding is superior to electrodes, right.. they have a machine that's even cheaper
12:09 PM Tom_L: you'll need some inert gas
12:09 PM Tom_L: i certainly wouldn't use that crappy flux core wire
12:10 PM Tom_L: it spatters too much
12:10 PM t4nk_freenode: mmm it is supposed to work without gas
12:10 PM Tom_L: nope not unless you use flux core wire
12:10 PM Tom_L: needs an oxygen barrier
12:12 PM t4nk_freenode: so I guess it is using flux core
12:12 PM t4nk_freenode: 'wire is made of steel with protective gas( in solid form)' it says
12:12 PM Tom_L: yup, flux core
12:13 PM t4nk_freenode: one of the comments also stated it didn't splatter too much
12:13 PM Tom_L: bullshit
12:13 PM t4nk_freenode: but I guess I can forget about welding in the living room then ey :|
12:13 PM Tom_L: only place i would use it would be outside in the wind
12:13 PM Tom_L: no go ahead and set the house on fire
12:14 PM t4nk_freenode: lol
12:14 PM * Tom_L hits t4nk_freenode with a clue bat
12:14 PM t4nk_freenode: I got a balcony
12:15 PM Tom_L: you _had_ a balcony
12:15 PM t4nk_freenode: lol
12:24 PM Tom_L: t4nk_freenode, doesn't look like that one has any current control, just wire feed
12:26 PM t4nk_freenode: 'automatic setting of current and wire feed' it says
12:26 PM t4nk_freenode: and the button on front is supposed to represent the thickness of the material you're welding
12:27 PM t4nk_freenode: from .8-3mm
12:27 PM Tom_L: mkay
12:27 PM t4nk_freenode: so I guess you can't control current and feed really separately
12:31 PM roycroft: if you cannot adjust those parameters independently then the machine is all but completely useless
12:31 PM Tom_L: i don't see where you would reverse polarity for electrodes either
12:32 PM roycroft: tom_l: i don't know what this machine is, but on a lot of small mig welders polarity is set by moving the postive and negative wires inside the unit by the wire feed
12:32 PM roycroft: spool
12:32 PM Tom_L: flux core requires negative electrode where solid wire is positive
12:32 PM Tom_L: i know but i didn't see any place to do that in the wire feed side
12:33 PM roycroft: ok
12:33 PM roycroft: again, i don't know what this machine is - i did not see the original link to it
12:33 PM Tom_L: https://www.lidl.nl/p/parkside-vuldraad-lasapparaat/p100342661
12:33 PM t4nk_freenode: it's only 120euros though, can't expect too much of course
12:33 PM Tom_L: i call them body shop welders
12:34 PM t4nk_freenode: and well.. I guess you can always mod to control the feed
12:34 PM Tom_L: but why?
12:34 PM roycroft: but it doesn't matter
12:34 PM Tom_L: get one that is actually useful
12:34 PM t4nk_freenode: that would leave the main rotary as the current
12:35 PM roycroft: if the feed rate and current cannot be adjusted independently then the only good reason to buy it is as a cheap christmas gift for a guy who likes to hang out in his garage and drink beer and look at his tools, but never uses them
12:36 PM roycroft: and if there's no way to reverse polarity, there's also likely no way to hook up a gas cylinder to the machine
12:36 PM roycroft: and you're stuck with flux core only
12:36 PM t4nk_freenode: but a real welder is like a trillion dollars
12:37 PM t4nk_freenode: in any case way, way more expensive
12:37 PM roycroft: actually, they can be had fairly inexpensively
12:37 PM roycroft: i would argue that that one is more expensive, though, as it's almost useless
12:39 PM roycroft: it's like flushing 120 euros straight down the crapper
12:39 PM t4nk_freenode: lol
12:39 PM roycroft: buying a lottery ticket is almost a better value
12:40 PM roycroft: you should be able to get a machine for about 200-250 euros that can reverse polarity, has separate feed rate and current controls, and can be fitted with a gas cylinder as an add-on

01:07 PM XXCoder: awesome. new cpap holder worked better than I expected
01:15 PM XXCoder: JT-Cave: knew it, inverting holder curved worked so well. it cut friction so much
01:18 PM _unreal_: ok.. just got my work piece held down
01:19 PM _unreal_: sucks I'm going to have to do a few adjustments in my clamping as I do the milling job.
01:19 PM _unreal_: no way around it.
01:19 PM Tom_L: M1
01:19 PM Tom_L: no biggie
01:20 PM Tom_L: just make sure you turn the spindle back on afterward
01:20 PM Tom_L: i have a macro in my cad cam to add it all in
01:21 PM Tom_L: spindle off, pause, spindle on, continue
01:46 PM XXCoder: tom the new design worked very well :D
01:47 PM Tom_L: so i heard
01:47 PM XXCoder: good thing. it'd be hassle on having to remove pin locks hard way
01:49 PM _unreal_: roycroft, with the new z setup I'm adding an independent dust shoe. depending on which controller I decide to control this machine with in the end. I may even add a stepper to drive the brush
01:50 PM _unreal_: brush=dust shoe
01:56 PM roycroft: i was going to add a stepper for adjusting the height of my dust shoe, but thinking about my uses for the machine, i think that manually adjusting it at the beginning of a job will suffice, for now at least
01:56 PM roycroft: i designed the spindle assembly to accomodate that stepper if i want to add it later
01:57 PM roycroft: to me it's much more important that the dust shoe be independent of the spindle than that it be programatically adjustable
02:03 PM Tom_L: linear stepper
02:06 PM _unreal_: still toying with methods of motorizing a dust shoe
02:09 PM _unreal_: and I think I have a nice setup worked out on how to switch between z up/down control and independent control. but then again just being able to tie it to the Z or tie it to a fixed stop independent of the z would be nice as well.
02:17 PM roycroft: some folks use spring-loaded dust shoes
02:17 PM roycroft: low tech, but it may work well in some applications
02:18 PM CaptHindsight[m]: JFC that guy trolling here for why LCNC doesn't talk Mach3 over Ethernet has been trolling the dev mail list, he acts like he doesn't understand simple English
02:19 PM CaptHindsight[m]: can't want for all the CNC expert code he will soon spew out yet again revolutionizing open source CNC controls
02:20 PM CaptHindsight[m]: well does give gene somebody to talk to
02:22 PM Tom_L: his idea is better than all the rest
02:37 PM CloudEvil: CaptHindsight[m]: I am reminded of a guy that stood up at an open source mobile phone conference and asked 'and what does JPEG stand for?'
02:38 PM CloudEvil: (it was a tangential mention only, with no relevance to the topic)
02:38 PM CaptHindsight[m]: of course

02:51 PM CaptHindsight[m]: https://forum.linuxcnc.org/27-driver-boards/44422-colorcnc-colorlight-5a-75e-5a-75b-as-fpga-controller-board the boards they are using start at $16
02:51 PM CaptHindsight[m]: aren't the Mach3 Ethernet modules quite more?
02:53 PM CaptHindsight[m]: and Remora supports it anyway https://forum.linuxcnc.org/18-computer/44828-remora-ethernet-nvem-cnc-board?start=0
02:56 PM _unreal_: sigh... have to leave in an hour. dont think I have enough time to mill the last part(S) of this part I'm making for the new cnc machine
02:57 PM _unreal_: but regardless I just got the holes drilled in my plate. this plate is the TRUE flat plate that will mount to the carriages on the Y axis leaner bearing
02:58 PM _unreal_: got both plates holes drilled all part of one bit of metal right now. I still need to mill off the end with the cnc. then use the CNC to scribe a cut line to cut them in half on the bandsaw when I get to it.
03:00 PM _unreal_: once that is done. I can clean up the holes. mount/bolt them to the angle aluminum that they will mount on. and if I can. use the drill press to pop the holes in the angle aluminum. The good thing is that EXACT accuracey in the angle aluminum does not matter. because the X attachment system for the extrusion/rails is designed with adjustment
03:00 PM _unreal_: feels good to FINALLY get a part started
03:03 PM t4nk_freenode: so you got one fat bearing, and one leaner one
03:04 PM t4nk_freenode: did you use a drullpriss to drull the holles?
03:04 PM t4nk_freenode: or the cnc?
03:06 PM t4nk_freenode: ah, right, the drulpriss it is
03:07 PM _unreal_: I have a nice drill press (hatachi), two bandsaws one is a large upright 93" the other is a really small tri wheel bandsaw. I got a port a band, thats one of those portable metal cutting hand held band saws. and planty of other fun tools
03:09 PM _unreal_: when I leave this house. I cant wait to get my little tri band setup again. right now its just collecting dust in the attic buried. sigh
03:10 PM _unreal_: well time for a quick shower then leaving soon to get the kid
03:20 PM klacnc: Hallo! ich bin hier neu und freue mich auf einen wertvollen Austausch mit Linuxcnc Anwendern!
03:24 PM Tom_L: klacnc, awesome... english will get you furthere here though

03:34 PM Tom_L: damn you ran him off!
03:34 PM t4nk_freenode: lol
03:35 PM t4nk_freenode: he outright left!
03:46 PM CaptHindsight[m]: well don't take it personally, it's late in Germany
03:46 PM CaptHindsight[m]: some people have to work in the morning
04:06 PM t4nk_freenode: it's not that late in Germany
04:07 PM t4nk_freenode: and some ppl are working right now
04:13 PM CaptHindsight[m]: t4nk_freenode: is too
04:13 PM t4nk_freenode: it's not even 11pm
04:14 PM CaptHindsight[m]: so you're the guy that calls people at home after 8pm?
04:14 PM t4nk_freenode: wow, you're going to Heaven for sure
04:15 PM CaptHindsight[m]: sorry your highness
04:15 PM t4nk_freenode: like I said.. Heaven ;)
04:17 PM CaptHindsight[m]: uh huh

06:10 PM JT-Shop: been a long ride to get to this point
06:10 PM CaptHindsight[m]: JT-Shop: did you change the LPT settings chooser in Stepconf?
06:10 PM JT-Shop: I don't mess with stepconf
06:11 PM JT-Shop: I have enough to work on lol
06:11 PM JT-Shop: github will tell you who worked on it
06:11 PM CaptHindsight[m]: I noticed in 2.9 that it gives you only choices of LPT 1, 2 , 3 etc vs let you type in the hex address
06:14 PM JT-Shop: https://github.com/LinuxCNC/linuxcnc/commits/master/src/emc/usr_intf/stepconf
06:16 PM CaptHindsight[m]: ah hah! https://github.com/LinuxCNC/linuxcnc/commit/06a34258f8603b46614f2f47186b02a6e65edebc
06:17 PM JT-Shop: there you go
06:18 PM CaptHindsight[m]: for some reason I thought that stepconf was something you worked on, sorry for the confusion
06:19 PM JT-Shop: I think Jeff or Chris started that
06:19 PM JT-Shop: I worked on the documents for 10 or so years
06:25 PM CaptHindsight[m]: ah probably why I confused that
06:26 PM CaptHindsight[m]: I'm working on openCV widgets for QTPYVCP
06:26 PM * JT-Shop wanders inside
06:26 PM JT-Shop: cool
06:26 PM CaptHindsight[m]: edge and corner alignment, measurements by camera
06:26 PM JT-Shop: wow
06:27 PM JT-Shop: qtpyvcp is cool
06:27 PM CaptHindsight[m]: yes, very handy
06:27 PM XXCoder: from what I saw on your articles, definitely
06:27 PM CaptHindsight[m]: find hole centers, measure dia. etc
06:27 PM JT-Shop: aye you can make it what you want not what some programmer wants
06:28 PM JT-Shop: say goodnight Gracie
06:28 PM CaptHindsight[m]: try that with siemens, heidenhain, fanuc etc
06:30 PM JT-Shop: that's why my configuration tool allow you to make anything you need not some predefined machine... if you have a X U machine you can make the configuration

06:43 PM solarwind_: I wonder if it's worth investing in a natural gas compressor so I can run my forklifts on CNG instead of propane
06:43 PM solarwind_ is now known as solarwind
06:44 PM solarwind: I use maybe like 3 x 30lb propane cylinders a month which comes to about $80/month
06:48 PM CaptHindsight[m]: keep away from sparks
06:50 PM solarwind: Well that applies to all volatile fules
06:50 PM CaptHindsight[m]: solarwind: i can't imagine being able to do that anywhere inside or even within city limits
06:51 PM solarwind: Not true, they sell residential compressors for CNG powered cars
06:51 PM solarwind: I was reading that somewhere a while ago, just can't find it
06:53 PM CaptHindsight[m]: https://www.ebay.com/itm/264141569315
06:54 PM solarwind: Ok so question answered, not worth it

06:57 PM solarwind: On another note, my scissor lift came filled with automatic transmission fluid, which seems to be popular for some reason for hydraulic applications
06:57 PM solarwind: I want to replace it with AW hydraulic oil, but obviously some ATF will remain
06:57 PM CaptHindsight[m]: "can be installed “anywhere” that is consistent with local codes
06:57 PM CaptHindsight[m]: and regulations for cylinder filling. "
06:57 PM solarwind: Should be safe to mix it right? O
06:57 PM solarwind: Or maybe I have to purge it with old hydraulic oil or something
06:58 PM solarwind: Why do people use ATF anyway?
06:58 PM Tom_L: why not?
06:58 PM solarwind: Because AW hydraulic oil is specifically designed for standard hydraulic systems
06:59 PM solarwind: It doesn't get any more standard than a gear pump and cylinders
06:59 PM solarwind: I think the difference is that ATF is a detergent oil and AW32 is non-detergent

07:05 PM solarwind: It's a Skyjack SJ4626. The recommended oils are either ATF or mineral AW46, but not synthetic hydraulic oil what the hell?
07:06 PM solarwind: I bought this thing for $1,500 lol and it works perfectly minus a worn control panel that'll take me a weekend to fix
07:07 PM solarwind: Well batteries were dead obviously but I have a fat stack of LiFePO4 that settled right in very nicely b
07:14 PM _unreal_: just got home. let the noise fest of milling begin.
07:27 PM _unreal_: god I hate cutting hardened aluminum on my machine
07:27 PM _unreal_: always a pain. because my mini cnc can only do high RPM bits
07:27 PM _unreal_: sigh
07:33 PM _unreal_: nothing like sitting in my bedroom with hear protection on
07:33 PM _unreal_: sigh
07:34 PM Tom_L: what chip load?
07:37 PM _unreal_: ahh small
07:38 PM _unreal_: I'm using a single flute up cut.. its all I have on hand curently
07:38 PM _unreal_: I have one more two flute strait but I'd rather save that till I get re-stocked.
07:38 PM _unreal_: I need to find some good cheap upcut two flute bits or aluminum that are $$$ CHEAP
07:39 PM _unreal_: I'm running about 14300 ish rpm
07:39 PM Tom_L: find some 3 flute
07:39 PM Tom_L: i started using them and plan to stay with em
07:39 PM _unreal_: any amazon example suggestions?
07:39 PM Tom_L: what diameter?
07:39 PM _unreal_: I typically go for the knock off china ones
07:39 PM _unreal_: 1/8th shank
07:39 PM _unreal_: 1/8th bit
07:40 PM _unreal_: I can go larger but I need the 1/8th cutting end
07:40 PM Tom_L: http://onlinecarbide.com/endmiforal.html
07:40 PM Tom_L: break down and get a couple of those
07:40 PM Tom_L: 3
07:40 PM Tom_L: min order..
07:41 PM _unreal_: I may, when I have the cash on hand too
07:41 PM _unreal_: right now my $ is getting dumped into stocks
07:41 PM _unreal_: HUGE market run comming
07:42 PM _unreal_: If My cards play out as expected.... :) I may be a very $ happy person soon
07:43 PM Tom_L: you been sayin that since you arrived here...
07:43 PM XXCoder: ok ill make it happen. when it does, you cost me million usd
07:43 PM _unreal_: ?
07:44 PM _unreal_: I'm heavy in amc, weed, energy stocks right now.
07:44 PM _unreal_: all are going to make crazy runs
07:44 PM _unreal_: when ever the market squeeze happens
07:44 PM roycroft: amc shot up almost 1000% early last year
07:44 PM _unreal_: and likely june
07:45 PM _unreal_: CEI is likely to have a HUGE run up in the next few months as well
07:45 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/cutters/Lakeshore_vs_Online1.jpg
07:45 PM roycroft: it's down to 160% over last year now
07:45 PM _unreal_: currently under a dollar. I'm betting $5-25 you watch
07:45 PM Tom_L: lakeshore are a tiny bit nicer but cost more
07:45 PM roycroft: i guess reddit got tired of hyping it
07:45 PM Tom_L: running them you can't really tell the difference
07:45 PM XXCoder: is it just me or does lakeshore endmill flute vary?
07:46 PM _unreal_: vary in what way
07:46 PM Tom_L: any good carbide endmill for aluminum has a variable flute angle
07:46 PM roycroft: so i want to know if i'm chasing something i'll never catch
07:46 PM Tom_L: it's for noise
07:46 PM Tom_L: chatter
07:46 PM XXCoder: oh interesting
07:46 PM roycroft: i'm trying to use the same design table in a bunch of different solidworks parts
07:46 PM roycroft: and i'm having a heck of a time doing that
07:47 PM roycroft: i've used tables heaps of times for individual parts, but i want to share the data between a number of parts now
07:47 PM roycroft: does anyone have an idea if that's likely to work?
07:48 PM Tom_L: i haven't done it with sw just catia but it should be the same
07:48 PM roycroft: my thinking is that when i want a new configuration i just open the table in excel, add/alter whatever i need to do, and all the parts automagically update
07:48 PM Tom_L: don't you just define which elements are associated in the table row/col?
07:48 PM roycroft: yes
07:49 PM roycroft: and i did that with the first part
07:49 PM roycroft: and then created a bunch of variants in that part, and that all works fine
07:49 PM roycroft: which it should, as i've done that heaps of times
07:49 PM roycroft: but then on the second part, i labeled the dimensions the same as on the first part
07:49 PM roycroft: then i inserted a design table
07:50 PM roycroft: and chose the existing one for the first part
07:50 PM roycroft: and it only imported the first column of the first row
07:50 PM roycroft: and told me everything else was invalid
07:50 PM Tom_L: start 2 new parts and have 1 element in each one and get that to work
07:50 PM Tom_L: go from there
07:50 PM roycroft: i double checked that the dimensions were identical
07:50 PM roycroft: well, maybe not in value
07:50 PM roycroft: but they were labeled identically
07:51 PM Tom_L: there probably can't be any unused elements in the table
07:51 PM roycroft: yeah, maybe i should do it with a single column for a test
07:51 PM roycroft: i'm actually pretty happy with what i'm doing right now
07:52 PM roycroft: my new gpu is not going to arrive for another week, and working on my router design is painfully slow
07:52 PM roycroft: i decided to set that aside until the new gpu is here, and work on some storage cabinets in the meantime, which is a much simpler design
07:53 PM roycroft: but when i decided to try to use this single design table for multiple parts, i realised that would also make the router design a lot easier
07:53 PM roycroft: i'm tired of entering the same dimensions in a half dozen places, and having to update each part whenever i change it, and i've been doing that a lot on the router design
07:53 PM Tom_L: XXCoder, it's not enough that you can see
07:55 PM Tom_L: XXCoder, https://www.the-carbide-end-mill-store.com/EndMillBlog.html?m16:post=variable-flute-end-mills-carbide-htc-series-800-4-flute-standard-length
07:56 PM _unreal_: I cant see my self with an auto tool changer. but I am thinking about making an auto tool choice rotary setup with this rotary bed I have
07:56 PM _unreal_: I have talked about it before.
07:58 PM _unreal_: I'm thinking about making some kind of a tray system with LED's etc... and lots of holders, for collets, and bits. make a 3/4 cover 1/4 exposed for selecting the bit to be used. and a few strips of LED's to light up what selecting is being made
07:58 PM _unreal_: will be interesting if I ever build it. trying to interface it
07:58 PM _unreal_: would likely be some serial driven system with arduino at the core
07:59 PM roycroft: for my cnc router i don't see any way to justify an automatic tool changer, ever
07:59 PM roycroft: for my small mill, the same
07:59 PM Tom_L: i got too many holders to change to something else now
07:59 PM roycroft: if i ever get a bridgeport class mill or larger, and make a signficant amount of my income from cnc milling jobs, perhaps
08:01 PM Tom_L: i never will so i'm just making the best of what i have now
08:12 PM roycroft: the chances that i'll ever make a significant amount of my income with a cnc bridgeport class mill are pretty slim
08:12 PM roycroft: so the chances i'll ever install an automatic tool changer are pretty slim
08:16 PM roycroft: not that there's anything wrong with that
08:16 PM roycroft: it's just not even close to my primary interest
08:17 PM Tom_L: you're all about wood i think
08:17 PM roycroft: that's my primary material of interest
08:18 PM roycroft: ok, so i just made a very simple part with a design table to drive the dimensions
08:19 PM roycroft: and then i made another, almost identical part, and used the same design table, and that worked
08:19 PM roycroft: so it can be done
08:20 PM Tom_L: now just figure out what is different
08:21 PM roycroft: i think i know
08:21 PM roycroft: while the dimension tags were the same in both parts on the original attempt, they were in different sketches
08:21 PM roycroft: i think i need to make sure that tag@sketch is the same on all of them
08:22 PM roycroft: which means doing some relative dimensioning, as well as table-driven dimensioning
08:23 PM roycroft: i just hope that i can make it work on parts where some of the dimensions are not needed
08:23 PM roycroft: i guess that should be my next test
08:25 PM roycroft: what's odd is that i'm not finding much information about doing this anywhere - not in my solidworks books, not on youtube, dassault systemes forums, no where
08:25 PM roycroft: it seems like something every person using the software for any kind of serious design work would be doing on a regular basis
08:26 PM roycroft: now i only took one intro to solidworks class, but tables were not even mentioned at all during the course
08:26 PM roycroft: not even simple things like bom tables
08:26 PM roycroft: there must be some magical solidworks academy that one goes to to learn this stuff
08:26 PM roycroft: which probably involves catching a train on platform 9-1/2 to get to
08:28 PM Tom_L: i figured it out on my own
08:29 PM roycroft: i'm doing so as well, but slowly
08:29 PM roycroft: my point is that i'm making a lot of mistakes in learning how to do it
08:29 PM Tom_L: https://www.engineersrule.com/getting-started-design-tables/
08:30 PM roycroft: i'm learning from those mistakes, but a good tutorial would help avoid making some of them
08:30 PM roycroft: yeah, that's super basic
08:30 PM Tom_L: https://www.javelin-tech.com/blog/2020/04/solidworks-design-tables/
08:30 PM roycroft: and making one for a single part drawing is easy
08:31 PM roycroft: it's using the same table in multiple parts that gets tricky
08:31 PM roycroft: and slightly less tricky is adding one to an assembly
08:32 PM Tom_L: they shine when you have a series of parts
08:32 PM Tom_L: if they become too dissimilar then it's hardly worth it
08:33 PM roycroft: right now i'm working on a set of drawers
08:34 PM roycroft: i have 7 different size drawers, each of which consists of 5 parts
08:34 PM roycroft: most of the dimensions are identical in all of them, of course
08:34 PM roycroft: but overall height, width, and length may vary
08:34 PM roycroft: that's a perfect application for a design table
08:36 PM roycroft: and it looks like i'm going to end up with two different width carcases, so a design table would be perfect for that as well if i don't want to draw the horizontal parts twice
08:37 PM * roycroft is trying to keep it simple until he gets this all sorted

09:35 PM roycroft: there was an interesting report on npr this morning about an odd effect of the war in ukraine
09:36 PM roycroft: musicians all over the world have having difficulty keeping their equipment working, as tube amplifiers are still highly desired and in wide use, and most vacuum tubes these days are made in russia
09:36 PM roycroft: peter frampton was being interviewed and he was saying it's turning into a serious problem
09:37 PM roycroft: i'm not sure i'd advocate strongly for bringing vacuum tube manufacturing back to the us
09:37 PM roycroft: but it would be good if russia did not have an almost total monopoly on that market
09:37 PM roycroft: or any other market, for that matter
09:52 PM acer is now known as _unreal_

11:30 PM XXCoder: yeah'
11:30 PM XXCoder: they can sell stuff to themselves
11:30 PM XXCoder: we got rest of world
11:31 PM roycroft: as i said a few days ago, the tiny sliver of a silver lining in this war may be that we reduce our dependency on countries like russia and start being more self-sufficient
11:32 PM XXCoder: globalizion is great thing, if it didnt exploit so much things, and depends on horrible countries
11:32 PM XXCoder: like russia and china
11:32 PM roycroft: globalization has not worked out very well, imo
11:32 PM XXCoder: oh it did, very much did
11:55 PM XXCoder: after all, there simply isnt enough industries to supply everything we use in current modern life
11:55 PM XXCoder: we need globalizion. issue is that it turned into exploitive for very cheap labor for massive profit
