03:07 AM pink_vampire: robotustra: are you using lead screws???
04:49 AM JT-Cave: morning
04:49 AM XXCoder: yo
06:06 AM Tom_L: morning
06:06 AM XXCoder: yo
06:08 AM Tom_L: 62F / 81
06:19 AM Tom_L: _unreal_, https://mesaus.com/product/spinx1/
06:49 AM robotustra: pink_vampire|2, yes, why not?
06:51 AM Loetmichel: Hmm, is it possible that 6870 drill are a bit much for Cambam(CAM tool) ... its crashing for the tird time in a row now while generating gcode :-(
06:51 AM XXCoder: cambam = crash like bamb soon
06:51 AM Loetmichel: cant say taht
06:52 AM Loetmichel: for me its pretty stable. first time i have issues with crashing
06:52 AM XXCoder: last time I tried it kept crashing each time i try something. probably lot of it fixed by now I guess
06:53 AM XXCoder: anyway its possible its memory overflowing?
06:53 AM XXCoder: save a backup and remove 1000 drills
06:53 AM XXCoder: then again another 1000 till it suceeds on making gcode
06:55 AM pink_vampire: XXCoder: back to my original nick
06:55 AM XXCoder: yay
06:57 AM robotustra: pink_vampire, I'm using lead screws
06:57 AM pink_vampire: how you don't have backlash?
06:59 AM robotustra: I have, but reasonably small
06:59 AM robotustra: if I put a spring nut I can remove it completely
06:59 AM Loetmichel: yeah, it crashses with an out of memory error
06:59 AM robotustra: like antibacklash nut
06:59 AM XXCoder: Loetmichel: if you succeed, you could just make 2 gcodes, remaining ones and inverted selection of drill holes. you can then just copy paste drills into first and have complete gcode heh
07:01 AM Loetmichel: yo, thats proably the best
07:01 AM Loetmichel: or jsut use three oerations and dont do all 68070 drisll in one
07:02 AM XXCoder: ah seperate section maybe, depends on how it caches before writeout
07:04 AM Loetmichel: yes, "mark all" was a bad decision.
07:04 AM Loetmichel: *waaait*
07:05 AM XXCoder: doh lol
07:05 AM XXCoder: this is why cam machines tend to be really badass computers
07:05 AM robotustra: what is this cam?
07:05 AM XXCoder: cambam
07:05 AM robotustra: is it free?
07:05 AM robotustra: opensource code?
07:06 AM XXCoder: nah windows closedsource
07:06 AM XXCoder: 150 usd, but free fir certain limitions
07:06 AM Loetmichel: indeed
07:06 AM Loetmichel: but for me: 150$ well invested
07:07 AM Loetmichel: 2,5D cam
07:07 AM Loetmichel: can do 3d, but not very well
07:07 AM robotustra: I dream to srite a cad open source and usable to f**k up all not free cad companies
07:07 AM robotustra: create
07:08 AM XXCoder: freecad has cam its not much good but it exists
07:08 AM XXCoder: ich was working on previews of it when he died
07:09 AM robotustra: free cad developers are too much oriented on small things and do not fix core things
07:09 AM XXCoder: more reprap users than cnc users
07:10 AM XXCoder: cad is good enough to make objects to print
07:10 AM XXCoder: cam is useless for 3d print as they use slicers.
07:12 AM robotustra: where is this cambam is designed?
07:13 AM robotustra: it looks like it's a rather new thing
07:13 AM XXCoder: nah its few years old
07:13 AM XXCoder: i last tested it in what 2016? forgot
07:26 AM robotustra: thinking how to make good chips guard and chip removing system
07:36 AM pink_vampire: flatcam work perfect for 2d
07:36 AM pink_vampire: free and open source
07:37 AM XXCoder: oh great their site uses medium gray text and white background
07:37 AM pink_vampire: robotustra: cambam is OLD stuff
07:37 AM XXCoder: *and medium gray text and dark gray bacground.
07:38 AM XXCoder: Loetmichel: did it work?
07:40 AM pink_vampire: XXCoder: what is the issue with that?
07:40 AM XXCoder: so many drill spots that cambam runs out of memory making gcode
07:42 AM robotustra: pink_vampire, but it's mainly for PCBs?
07:42 AM pink_vampire: XXCoder: I mean what is the problem with the gray bg?
07:42 AM XXCoder: low contrast.
07:43 AM XXCoder: that ones not too bad, I can still read but its not great.
07:43 AM pink_vampire: robotustra: yeah, but you and import DXF and SVG
07:45 AM robotustra: I was using artcam, but for the simple parts I recently started to write g-code by hands
07:46 AM pink_vampire: flatcam is flying for 2d
07:46 AM robotustra: because artcam is doing tons of stupid things, like interpolating circles by lines
07:46 AM robotustra: instead of using G2 and G3
07:47 AM pink_vampire: this is sounds like a post problem
07:47 AM pink_vampire: but flat cam do it also
07:48 AM robotustra: and for instance I can't do helical move in artcam
07:48 AM pink_vampire: what are you making?
07:48 AM robotustra: cnc lathe
07:49 AM pink_vampire: with artcam?!?!
07:49 AM robotustra: :)
07:49 AM robotustra: why not?
07:49 AM robotustra: artcam is the only g-code generated part
07:50 AM pink_vampire: I don't think artcam even support turning operations
07:50 AM robotustra: I use another cad for drawing parts
07:50 AM robotustra: no, I build cnc lathe but milling parts on cnc router
07:51 AM pink_vampire: what are you using for cad?
07:51 AM robotustra: g-code generated by artcam I run on cnc router
07:51 AM robotustra: t-flex
07:51 AM robotustra: old old version,
07:51 AM pink_vampire: O_o
07:51 AM robotustra: like v.11
07:52 AM pink_vampire: sounds like pain
07:52 AM robotustra: not at all
07:52 AM pink_vampire: some people pay for pain
07:52 AM robotustra: it's for free
07:52 AM robotustra: for me
07:53 AM pink_vampire: why not solidworks?
07:54 AM pink_vampire: and then you can use hsm or camworks
07:54 AM robotustra: solidworks 10 times bigger and about 5 times slower that t-flex
07:54 AM robotustra: with the same functionality
07:54 AM robotustra: I'm not kidding you
07:54 AM robotustra: it's just a fact
07:54 AM robotustra: t-flex is written in c++
07:55 AM robotustra: solidworks is using .net
07:55 AM robotustra: if you understand what I mean
07:55 AM pink_vampire: most of the industry use solidworks.
07:56 AM robotustra: I'm not an industry. Are you sure the "industry" goes right direction?
07:57 AM robotustra: I want to take right decisions I like in my shop :)
07:59 AM Loetmichel: XXCoder: "cambam is thinking"
07:59 AM Loetmichel: takes a while
07:59 AM Loetmichel: we'llmse
07:59 AM robotustra: I'm trying not to use negative technologies, which upsets or irritates me during the use of them
08:00 AM robotustra: windows and .net are examples of such negative technologies
08:01 AM robotustra: windows is still alive just because it's more than 50% of linux inside
08:02 AM pink_vampire: O_O
08:04 AM Loetmichel: robotustra: i doubt it.
08:04 AM Loetmichel: very much
08:04 AM Loetmichel: windows is (sadly) nothinglike linux
08:04 AM Loetmichel: no simialr api calls, no simiar user concept, nothing.
08:05 AM pink_vampire: what part of linux is the next next next finish?
08:13 AM robotustra: Loetmichel> robotustra: i doubt it.
08:13 AM robotustra: don't mix system calls and the source code
08:13 AM robotustra: linux code is used in windows since win2000
08:14 AM robotustra: and yes, windows does not have file system
08:15 AM robotustra: that's why it's so easily can be hacked
08:20 AM * Rab squints
08:20 AM Rab: BSD code in the networking stack, I think...
08:23 AM robotustra: probably
08:24 AM robotustra: I remember the network stack was completely rewriten one day from scratch
08:24 AM robotustra: on linux
10:11 AM colten: Linux tormachpcnc 4.9.231-rt148 #1 SMP PREEMPT RT Fri Jul 24 18:16:00 CST 2020 x86_64 x86_64 x86_64 GNU/Linux
10:11 AM colten: anyone else experience seemingly random lockups?
10:12 AM colten: vmlinuz-4.11.9-rt7
10:12 AM colten: with that kernel I'm good, but the latency is horrific.
10:13 AM jymmmm: colten: what do the logs say?
10:13 AM jymmmm: re lockups
10:13 AM colten: nothing.. complete system lock
10:15 AM jymmmm: Have you isolated anything to see what is the cause?
10:17 AM colten: I know I need to disable kvm in bios or it get's worse
10:18 AM jymmmm: KVM?
10:18 AM jymmmm: Did you test the latency of this mobo already?
10:19 AM colten: yeah I did. it's good with the 4.9.231
10:20 AM colten: 20000-30000
10:21 AM jymmmm: 20K? seems high to me, usually 16K, but I suppose it depends on which scale is being used.
10:22 AM colten: servo is 18000, base is 22k
10:23 AM jymmmm: Yeah, someone else might be able to give you a better perspective than I, especially when it comes to servos
10:23 AM colten: using a 7i92 so jitter is not so important
10:24 AM colten: I'd just like to figure out this seemingly random lockup.
10:25 AM colten: I rebooted due to my keyboard/mouse being unresponsive, although ssh into the machine was working. had to reboot again almost immediately due to the lockup.
10:26 AM robotustra: may be overheat problems?
10:26 AM robotustra: cpu?
10:27 AM colten: i3 not sure what temp is. I'll have to reboot
10:27 AM robotustra: sometimes cpu can stall at overheat
10:28 AM robotustra: just to make sure it's not hardware problem before look into software
10:35 AM Loetmichel: robotustra: what i meant: Windows uses a completely different api/system call system than linux. EVEN IF the kernel had linux inside (and i doubt it apart from things like network stack and maybe arp and so on) its usueless if the system LOOKs different from outside callers
10:35 AM Loetmichel: Windows always used their own way deliberatly incompatible to the rest of the world when designing new interfaces
10:35 AM Loetmichel: ESPECIALLY for networking stuff
10:38 AM Loetmichel: XXCoder: yes, i got cambam to assmble the gcode... only 22mB drills
10:38 AM Loetmichel: ... next problem: LinuxCNC dont want to read it
10:39 AM Loetmichel: takes literally hours and still not finished to load and display.
10:39 AM Loetmichel: i think i have to split that into 4 different files, one for each tool/operation i made
10:39 AM Loetmichel: and then only load the one in question
10:54 AM Thorhian: Hey guys, I'm going to try and send a message to the seller to get the exact model of the driver for this thing, but how hard do you think it would be to use this as a spindle motor with lcnc (I'm using a 7i76 mesa card):
10:54 AM Thorhian: https://www.ebay.com/itm/254368271521
10:54 AM Thorhian: Also, jymmmm, banggood offered me $30 instead of my full refund this time XD
10:54 AM Thorhian: Might be time to talk to paypal.
11:00 AM jymmmm: Thorhian: Tell them, "This item is completely defective and unusable. Either replace the item or provide a full refund."
11:01 AM Thorhian: That's what I am going to do after I figure out how hard it will be to use this motor with LinuxCNC (the ebay link I just posted) jymmmm
11:02 AM colten: any reason I can't install a thcad-300 in my hypertherm 900 case without shielding it?
11:02 AM jymmmm: Thorhian: Ah, I have no clue on that ebay thingy =)
11:03 AM colten: was thinking that the location of the cpc boards that don't exist in my plasma cutter provide a nice easy location for it and the 5v ps
11:03 AM Thorhian: I just sent the seller a message to see what the specific model of the motor driver was. Hopefully from that I can see how difficult it will be to interface it to my mesa boards and have linuxcnc control it.
11:04 AM colten: damn it. mcmaster-carr cancelled my order
11:14 AM Thorhian: Wow, they strike again huh?
11:16 AM colten: yep. has to goto a business. can't be a personal order due to high cost of shipping
11:16 AM colten: guess again mcmaster. I'm paying the shipping no matter what
11:16 AM Thorhian: Oh, that sucks.
11:16 AM Thorhian: Wait, why is the shipping so high for a non-business? What are you ordering lol?
11:17 AM colten: just some oldham couplers. set screw type.
11:18 AM colten: some shims and some spacers
11:19 AM colten: stick it in an envelope and drop it off in a post office truck.
11:30 AM Thorhian: Wow, that doesn't seem like too much.
11:31 AM Thorhian: Also, now I'm wondering if it's okay to power these 220V servos drivers with 240V...
11:31 AM robotustra: Loetmichel, is your part so complex?
11:33 AM Loetmichel: robotustra: nope, just ~7k drills for a vacoom table
11:33 AM robotustra: :)
11:33 AM robotustra: different diameters?
11:33 AM robotustra: how many lines of g-code?
11:33 AM Loetmichel: stepped drill, yes
11:33 AM Loetmichel: no idea, about 21mb of gcode
11:33 AM Loetmichel: 22mb
11:34 AM robotustra: but why linuxcnc can't load it? is it trying to interpret it?
11:34 AM Tom_L: colten, just tell them you're colton incorporated
11:34 AM robotustra: like I told I'm a robotustra inc
11:36 AM Thorhian: I would go with Thorhian Labs lol
11:36 AM robotustra: Thorhian, most probably 240V for 220 servo will be ok
11:37 AM Tom_L: Thorhian pickle company
11:37 AM Tom_L: it _is_ a company
11:38 AM Thorhian: Nah, no pickling going on here Tom_L
11:38 AM Tom_L: unless they're planning to check you D&B rating you're good
11:38 AM Thorhian: Also, robotustra, are you familiar with driving AC servos?
11:39 AM Rab: I think 220-240VAC is the same nominal range, at least in the US. The literature for the servo drives should list absolute maximum power limits.
11:39 AM Thorhian: Thanks Rab
11:40 AM robotustra: Thorhian, yes, you just need VFD
11:40 AM Thorhian: Now I just have to get a hold of the documentation of the driver that comes with it.
11:40 AM robotustra: AC servo is just a AC motor with encoder
11:41 AM Rab: Thorhian, do you have mfg/model number?
11:41 AM robotustra: which sends the data to VFD to read RPM
11:41 AM Thorhian: I just sent a message to the seller of this motor/driver pair Rab for the model: https://www.ebay.com/itm/254368271521
11:43 AM robotustra: Thorhian, I got one similar to yours to but it on my cnc lathe
11:43 AM robotustra: but 1.2 rW
11:43 AM robotustra: kW
11:43 AM Thorhian: Nice lol
11:44 AM Thorhian: The driver seems a little more complex than a typical VFD, but I guess it's just a VFD with extra logic for the encoder input.
11:45 AM robotustra: yes, the documentation is long read but for my application there are actually 2 or 3 sections
11:45 AM robotustra: I already tested mine
11:45 AM robotustra: in continuous rotation mode
11:46 AM Thorhian: Nice.
11:46 AM Thorhian: I'm wondering if I should just buy at it after I get a refund from Banggood.
11:47 AM robotustra: but why 3.8 kW?
11:47 AM robotustra: what are you building?
11:47 AM robotustra: the motor on g0704 is only 740 W
11:47 AM Thorhian: *Shrug* Would that be bad for a mill spindle?
11:47 AM robotustra: it's 1 h.p.
11:48 AM robotustra: what is the rigidity of your mill?
11:48 AM Thorhian: I did mention 1hp seemed kind of lackluster for a mill spindle. Should I get something smaller?
11:48 AM robotustra: like 1.5 kW?
11:48 AM Thorhian: Why?
11:48 AM robotustra: which you can connect to 110V 15A power grid?
11:49 AM robotustra: usual one?
11:49 AM robotustra: as you wish
11:49 AM robotustra: if you are planning to mill big chunks of cust iron with high feeds
11:49 AM robotustra: then 3.8 kW is ok
11:50 AM robotustra: to connect 3.8 kW you need 2 phases with 110V
11:50 AM Thorhian: I mean I already have 240V easily accesible, and this motor and driver isn't that much more than the other 2.3 and 1.5KW motors.
11:50 AM robotustra: to connect 1.5 kW you need only 1 phase
11:50 AM robotustra: ok
11:51 AM robotustra: I mean if you put 3.8 kW spindle - all your other design should correspond to your spindle
11:51 AM robotustra: you can't put huge engine on flimsy machine
11:52 AM Thorhian: My father helped me out and put an extra 240V circuit in the garage. We bought a NEMA twist lock socket. Also, you are very correct on that point. I'm not experienced enough to be able to tell or calculate if my machine would be able to even handle it.
11:52 AM robotustra: and solid machine means == more money, whic you don't have or don't want to spend
11:54 AM robotustra: did you see g0704? it has 0.75 kW motor, if you put more power motor on it and start to push it - it will bend and you'll lose your precision, I can bend it how with hands and it play like 0.02 mm
11:54 AM Tom_L: robotustra, is that spindle pretty beefy?
11:54 AM Thorhian: The steel that will make up the machine frame along with the rails and ballscrews would only weigh 400 pounds by itself :/ (that is no stand underneath it of course).
11:54 AM Tom_L: i'm looking at one that is 750w and another that is 1.2kw
11:54 AM Tom_L: just curious if 750 is enough
11:56 AM Tom_L: i guess you can never have too much power
11:57 AM Thorhian: With all of the extra epoxy granite I plan on dumping into my Z column and possibly in the spindle mount, I think my machine would be a lot beefier and vibration dampening compared to that grizzly machine.
11:57 AM robotustra: 750W motor is rather big, like 150 mm in diameter and may be 200 mm of height
11:57 AM robotustra: I think it can give big torque
11:58 AM Thorhian: Define big torque, and at what RPM?
11:58 AM robotustra: at 0 rpm
11:59 AM robotustra: it has a regulator
12:00 PM robotustra: If I set like any RPM at speed controller - it will feed right amount of power to keep RPMS
12:00 PM Thorhian: I think 2.2kW might be more of what I would want rather than going for the 3.8kW.
12:00 PM robotustra: so, DC motor can give all 750W at 0 RPM just before stall
12:03 PM Thorhian: Also, just the steel that I have for my mill weighs more than the whole grizzly package. Thankfully hgr20 rails and their carriages are awesome.
12:03 PM robotustra: first I would desigt the machine and in the second path would chose the spindle power
12:03 PM Tom_L: Thorhian, started building it yet?
12:04 PM Thorhian: Yeah Tom_L I have. I've been grinding the metal by hand for a while and I've started tapping holes for my rails recently.
12:06 PM Thorhian: robotustra: the problem is that I am not a mechanical engineer. I don't know of a good way to exactly tell what I good spindle motor would be without just testing it.
12:06 PM Tom_L: Thorhian, gantry design?
12:07 PM robotustra: Thorhian, if you started to build a machine - the excuse like "I am not a mechanical engineer" does not work any more :)
12:07 PM Thorhian: No, the bed moves in X and Y, then I have a 8" x 4" steel column for the z rails, kind of like your machine Tom_L?
12:07 PM Thorhian: robotustra: XD
12:07 PM Thorhian: I mean, I'm a computer science student, not an ME major lol ;)
12:08 PM Thorhian: I'm not against learning though. Got any tips or teachings robotustra?
12:08 PM Tom_L: don't eat yellow snow
12:08 PM Thorhian: Pff.
12:09 PM Tom_L: have a solid plan before you start
12:10 PM robotustra: Thorhian, I'm a physicist and violin maker, and what? I'm building machines
12:10 PM robotustra: if you know haw to read and how to calculate according to formulas - you can build whatever you want
12:11 PM Thorhian: I mean I thought I had one towards the beginning, especially doing tons of research and asking questions on here for months Tom_L. Also, you are definitely not wrong robotustra.
12:12 PM robotustra: Thorhian, do you have a plan? I mean at least drawings?
12:13 PM robotustra: just outlines
12:13 PM robotustra: travel along axii, max load, max feeds?
12:13 PM robotustra: just for estimation
12:14 PM robotustra: budget
12:14 PM robotustra: we all live in limited resources world, so you have to define your limits first
12:14 PM Thorhian: Yeah robotustra, I roughly CAD'ed it out in Freecad along with doing calculations to see how much torque and RPMs I needed for milling at certain speeds for my steppers and ballscrews and how much force the rails would experience theoretically.
12:15 PM Thorhian: Also, yes, I did budget things out. The big pain point really has been the spindle motor situation I've had with banggood screwing me over and all.
12:15 PM robotustra: can you show your design?
12:16 PM Thorhian: I afraid you will laugh lol, but sure XD
12:16 PM Thorhian: Pics or the freecad file itself?
12:16 PM Thorhian: Oh wait, maybe just pics.
12:16 PM Thorhian: Assemblies in Freecad are kind of messy.
12:16 PM robotustra: don't be afraid if you are doing something
12:17 PM robotustra: I pic is good enough
12:19 PM Thorhian: Not everything in terms of parts are in the model, such as certain spacer blocks, motors, and ballscrews, but I did plenty of measuring with calipers to try and make everything was good since I already had the rails and ballscrews in person (and stepper motors).
12:19 PM robotustra: here is my lathe design for instance https://i.imgur.com/9o1FHsR.png
12:19 PM robotustra: doesn't matter
12:19 PM robotustra: just for me to imagine better what you are building
12:20 PM robotustra: https://i.imgur.com/73STFfW.png
12:20 PM robotustra: https://i.imgur.com/hdudtqC.png
12:20 PM robotustra: it's just an example
12:20 PM Rab: robotustra, why is the carriage offset from the spindle?
12:21 PM Tom_L: kinda like a slant bed lathe
12:21 PM Tom_L: with no slant
12:21 PM robotustra: to make it more compact in the height and put a toolchanger in the future
12:21 PM Thorhian: https://i.imgur.com/4KhIuNK.png
12:21 PM Thorhian: https://i.imgur.com/Q1TSVep.png
12:22 PM robotustra: so you are building classical vertical mill
12:22 PM Tom_L: Thorhian, don't weld solid beads all the way. it will warp too much
12:22 PM Tom_L: use shorter spaced beads
12:23 PM Thorhian: Tom_L: Already for that advice from my beast of a brother-in-law. Thank you though!
12:23 PM Thorhian: Also, yes robotustra
12:23 PM Rab: robotustra, I see, thanks.
12:23 PM Thorhian: Also, your lathe looks awesome robotustra
12:24 PM robotustra: Rab, current state: https://i.imgur.com/JfaIeJU.jpg
12:24 PM Tom_L: robotustra, hope your spindle motor is fully enclosed. it will get lots of swarf and coolant on it
12:25 PM Tom_L: between it and the spindle might be a haven for birds too
12:25 PM Thorhian: XD
12:25 PM robotustra: Thorhian, what is the base plate, what is the thickness of it?
12:25 PM Thorhian: All of the birds nests.
12:25 PM Rab: robotustra, nice!
12:26 PM Tom_L: yeah it looks great so far
12:26 PM robotustra: Tom_L, I go with 1.2 kW servo for spindle motor
12:26 PM Tom_L: when the time comes that's probably what i'll do
12:26 PM Thorhian: The base palte is a 1" thick piece of A53 steel. I plan on making it the top of a trapezoid filled with epoxy granite in the future when I get more money.
12:27 PM Tom_L: oh you meant for your lathe...
12:27 PM Tom_L: i may go that route on my mill as well
12:27 PM robotustra: Tom_L, yes on the lathe
12:27 PM Thorhian: The plate is 12" wide and 28" long.
12:28 PM robotustra: before I was thinking to put air cooling spindle motor 24000 rpm max with 1:8 reduction
12:28 PM robotustra: but decided that timing belts could be noisy
12:28 PM Tom_L: too hard on belts or gears
12:28 PM robotustra: so this one is 3000 rpm, but has constant torque of 4 Nm
12:30 PM robotustra: torque on low rpms is more practical on the lathe
12:30 PM robotustra: as soon as I'm planning to do a threads on it
12:31 PM Tom_L: that's what i'm looking for too
12:32 PM robotustra: I have to invent some chips guard on new mill on wheels and come back to lathe project
12:32 PM robotustra: thinking how to remove chips from tray and do not allow fly away
12:33 PM Tom_L: they get out no matter what
12:33 PM robotustra: on my small router they are not
12:33 PM robotustra: because they are in the box :)
12:33 PM Thorhian: lol
12:34 PM robotustra: but with manual thing I have to poke my hands during operation
12:34 PM robotustra: and the table can travel out of tray
12:36 PM robotustra: Thorhian, did you think about adjusting mechanisms yet?
12:36 PM robotustra: motor mounts?
12:36 PM robotustra: end stops?
12:37 PM robotustra: it's better to start thinking ahead to not place them after in the wierd places :)
12:37 PM robotustra: lubrication system
12:37 PM robotustra: chip guard
12:37 PM Thorhian: Adjusting mechansims for the best drive? Yes, I was getting some adive for that. I've been pondering about the stepper mounts.
12:38 PM Thorhian: I don't have money for a lubrication system at this time :/ I'm buying some neoprene rubber to make temporary chip cards for the rails and ballscrews.
12:39 PM robotustra: what travels are you planning?
12:39 PM robotustra: XYZ?
12:39 PM Thorhian: About 14" on X, 10" on Y, 500mm on Z.
12:40 PM robotustra: X = 350 mm, Y = 254mm, Z= 500mm
12:40 PM Thorhian: Yep
12:41 PM robotustra: for example g0704 has 490 mm on X, 156 mm on Y and 200 mm on Z
12:42 PM Thorhian: Yeah, that's too small in terms of Y for me.
12:43 PM robotustra: Thorhian, https://www.grizzly.com/products/Grizzly-10-x-33-2-HP-HD-Benchtop-Milling-Machine/G0720R
12:43 PM robotustra: just motorize it
12:43 PM Thorhian: Nah.
12:43 PM robotustra: :)
12:44 PM robotustra: Motorized head elevation
12:44 PM Thorhian: I'm sorry, but I'd still have to buy plenty to convert that, especially the lead screws.
12:44 PM robotustra: it already has motor on Z axis
12:45 PM robotustra: why?
12:45 PM robotustra: you don't need to
12:45 PM robotustra: just put antibacklash buts on ACME threads
12:45 PM robotustra: I'm planning to leave native lead screws
12:46 PM Thorhian: From everything that I have read, leadscrews aren't a good fit, and anti-backlash nuts just where out the screw even faster don't they? Besides, I am already building my mill.
12:46 PM robotustra: ok
12:47 PM robotustra: I had a reason to build my own lathe, I'm sure you have your reasons too
12:48 PM robotustra: I would buy a bigger mill like I posted to you if I had a garage
12:48 PM Thorhian: I'm not saying it's a terrible machine though. But with all of the materials I have already purchased and have started processing, there is no way I would slap 4 grand down on this grizzly.
12:49 PM robotustra: I know the situation
12:50 PM robotustra: because I was in it when I purchased a lot of stuff for tha lathe up to the "non return" point
12:50 PM robotustra: but even there I didn't turn back :)
12:51 PM Thorhian: You didn't turn back on building the lathe? Thats good.
12:51 PM robotustra: the specs of my lathe supposedly should be better than any existing table lathe :) at least I hope so they will be
12:52 PM Thorhian: Thats awesome lol.
12:52 PM robotustra: you don't find a table lathe with 40 mm spidle throu hole
12:53 PM robotustra: they just do not exist in the nature
12:53 PM Thorhian: The main inspirations for me building this mill have been Marco Reps, VinceBuild, and Kris Temmerman on YouTube.
12:56 PM Thorhian: I have a good feeling that my machine will be able to do fairly well, especially when I fill the column up with epoxy granite.
12:56 PM Thorhian: Plus, I'm really glad that I managed to get a BT30 spindle lol
12:56 PM robotustra: inspiration is ok, but machine is just a tool, I usually build tools to solve some tasks, do you?
12:57 PM Thorhian: Yep. I didn't start until I problems to solve :)
12:57 PM Thorhian: I had*
12:58 PM Thorhian: There is no way I would have done this if I didn't, especially as a college student lol
12:59 PM Thorhian: Thankfully I have access to a garage.
01:00 PM robotustra: so, if you have spare time, why are you chatting and not building you mill instead?
01:00 PM Thorhian: xD
01:01 PM robotustra: 1) run to your dream 2) if you can't run - walk, 3) if you can't walk - lay down in the direction of your dream
01:02 PM Thorhian: Partially because I'm distracted, and I've been researching motors for my spindle before I tell banggood to give my money back (again).
01:02 PM Thorhian: Also, nice saying.
01:03 PM robotustra: anyway, may be 3.8 kW spindle motor will be good for a size you want
01:04 PM robotustra: but still the similar machine for grizzly has only 1.5 kW spindle motor
01:04 PM Thorhian: Would you go with 2kW?
01:04 PM robotustra: yes
01:04 PM robotustra: 2kW is reasonable
01:05 PM robotustra: even 1.5 will work with AC servo
01:06 PM Thorhian: I'm thinking maybe this then: https://www.ebay.com/itm/264729624249
01:06 PM robotustra: a soon as you will have separate BT-30 spindle and separate motor - you can swap motor any time you'll decide you have lack of power
01:06 PM robotustra: and reuse the servo for some other project
01:07 PM robotustra: the only thing you will need to modify is a motor mount
01:07 PM robotustra: yeah, looks good
01:08 PM robotustra: this is mine https://i.imgur.com/ieZWLSc.jpg
01:08 PM Thorhian: That NEMA mount is a lot easier to deal with than the smaller BLDC motor I currently have in my possesion.
01:08 PM Thorhian: Also, nice
01:19 PM robotustra: and one more thing
01:20 PM robotustra: as soon as you are beginning machinist, you'll probably do not use aggressive cuts at high feeds, so to use the full power of your spindle you have to be sure what are you doing
01:23 PM robotustra: it's one more reason why you don't need powerfull spindle for the first couple of years before you get a lot of experience
01:24 PM robotustra: as for me - it's better wen you motor stall than you break you end mill
01:26 PM robotustra: power = speed * force, as soon as the spped is not high, power is not high too
02:05 PM Thorhian: Makes sense.
02:07 PM Thorhian: If I use a servo like this, should I still get another encoder for the spindle, or could I get away with just using the motor's encoder and some math to get spindle RPM? I'd be worried about slipping since I want to use a poly-V belt between the motor and spindle.
02:36 PM rmu: speaking of full power cuts, i just accidentally fed a 16mm carbide endmill through a 20mm thick piece of silver steel at 1500mm/min and 10000rpm. surprisingly, the endmilll survived (mostly), everything is covered in black steel chips that feel like plastic.
02:37 PM SpeedEvil: hp?
02:37 PM rmu: the spindle has 7,5kW i think. perhaps more.
02:38 PM rmu: do not recommend ;)
02:41 PM SpeedEvil: At least you know you tighten your collets right.
02:52 PM rmu: it's a hydrodehnspannfutter, don't know how it's called in english
02:59 PM Tom_L: clusterfuck?
03:00 PM Tom_L: loosely translated
03:01 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Vise_parts/Rotary1.jpg
03:01 PM Tom_L: just got that indicated in finally
03:11 PM veegee: I have this die grinder and love it: https://aircat.com/aircat/grinders/composite-angle-die-grinder
03:11 PM veegee: But how do you grease the gears? The manual doesn't say anything about a grease nipple but I think it's the little black thing on the side
03:11 PM Rab: Tom_L, looks good. Will you have a tailstock too?
03:12 PM veegee: I've never seen a grease nipple like that, how do you attach to it with a grease gun
03:12 PM Rab: Looks like a ball oiler. I don't think you would use grease at 18,000 rpm.
03:15 PM veegee: Rab they come pre greased
03:15 PM veegee: I can tell b ecause it slowly oozes out the spindle end
03:16 PM veegee: Feels like standard NLGI #2 grease
03:16 PM Rab: Push on the ball in the center of the black thing, see if it's spring-loaded.
03:16 PM veegee: Rab it is
03:17 PM veegee: I just don't know what kind of "coupler" to use on my grease gun
03:17 PM Rab: I don't believe there is a way to couple to a ball oiler, it's an ambient pressure device.
03:17 PM veegee: I guess some kind of needle?
03:18 PM veegee: Rab Oh maybe this? https://www.aircraft-tool.com/shop/dbpics/large/DL10546.jpg
03:18 PM Rab: Yeah, that'd be the best bet.
03:18 PM veegee: I have needle tips like that
03:18 PM Rab: yep
03:18 PM veegee: Also do you need to go through a process to set up a mcmaster carr account?
03:18 PM veegee: Like call them and make an account over the phone and all that
03:19 PM Rab: The parts diagram in the manual calls it a "grease fitting".
03:19 PM veegee: THey seem to have available many of the things I search for but I never bought from them
03:19 PM veegee: Yeah all their tools which have gears have a grease fitting
03:19 PM veegee: the manuals for some of them call it an "oil cup" but it's exactly the same as the rest of their tools and uses the same grease
03:20 PM veegee: The rotary tools gearing all seams fine to me. The air ratchets make me nervous. It's amazing that the mechanism lasts as long as it does
03:21 PM Rab: I've always set up accounts using just the website. But I pay with CC, I don't have terms. Some of my accounts are tax exempt, and I had to interact with humans through email for that IIRC.
03:21 PM veegee: it's so violent and makes the head heat up, especially on the reactionless air ratchet
03:21 PM veegee: Ok thanks, hopefully they have a Canadian site
03:22 PM Rab: Uhh heh heh, some Canadians here were complaining about ordering stuff from McMaster-Carr in the last 24 hours. They are strictly a US-based company, although I believe they can be persuaded to ship north.
03:24 PM veegee: https://www.amazon.ca/Astro-Pneumatic-101-Grease-Needle/dp/B000FMK7FG ah yeah the needle tip is the proper way to do it
03:25 PM XXCoder: Loetmichel: oh man too large for lcnc too
03:26 PM XXCoder: surpised too, since it should be able to handle it
03:26 PM Tom_L: Rab, yes i just haven't mounted it yet
03:27 PM veegee: I modified a grease gun by sealing the ends and using it as a pressure oiler for my vertical mill
03:27 PM veegee: the mill has grease nipples where oil should be used instead of grease
03:27 PM veegee: works surprisingly well
03:28 PM veegee: over lubrication for life baby. Oil is cheap. Worn gears are depressing sight
03:30 PM veegee: Time to make my compressor pump water cooled and run it at high speed, slightly over its rated 900 max RPM. Going to add fancy oil pumps and pressure lubrication to the crank case while I'm at it
03:51 PM Thorhian: So I want to take care of my ballscrews and linear rails. I don't know a whole lot about lubricating them properly though. I'd rather use grease compared to oil due to how messy it gets, but I don't know what kind of greases or oils I should get or what tools I should get. I can't afford an automatic oiler right now, but it will probably be something I get in the nearer future.
04:02 PM Rab: Thorhian, if your screws and rails are branded, the manufacturer should have a published recommendation for lubricants.
04:03 PM Thorhian: They are definitely not branded lol
04:04 PM Rab: Then your primary concern is compatibility with the existing grease. Maybe you can ask the vendor?
04:04 PM Thorhian: I'll do that.
04:06 PM veegee: Thorhian use oil
04:06 PM veegee: much easier to flush out. Debris WILL get stuck to grease
04:06 PM veegee: and it WILL make its way into the nuts
04:06 PM Rab: I have been researching that question for name-brand rails (IKO, Parker, etc) and Multemp PS No.2 comes up a lot. If you can't find a definitive answer, I'd go that direction: https://smile.amazon.com/dp/B015HJDDUM
04:07 PM veegee: Thorhian I use waylube ISO 68 for the ball screws on my vertical mill
04:07 PM veegee: It has a central oiler (hand pump operated) with the lines connected to all the various key places like the nuts and slideways and such
04:08 PM veegee: It's positioned such that the new oil will push out any debris
04:08 PM veegee: Do not use grease unless the system is sealed and there's no chance for dust and debris to reach the screws
04:08 PM Thorhian: I see.
04:08 PM veegee: greases are good. They're REALLY good. So good that they're next to impossible to flush out
04:09 PM veegee: get some fresh modern grease like Lucas xtra heavy duty and just _try_ to wash it off
04:09 PM veegee: nothing short of pumice hand cleaner will get it off, and that only works because it literally sloughs off a layer of skin along with the grease
04:10 PM veegee: apply it to your hands to see for yourself, that is
04:10 PM * roycroft wears nitrile gloves when handling grease
04:10 PM Thorhian: My ballnuts and rail carriages have places to put in lubrication lines. Guessing I should go with oil since I can't ensure nothing at all will get down the ways.
04:10 PM roycroft: and most other things
04:10 PM Rab: Thorhian, the cheap chinese rails seem to be Hiwin clones. Hiwin have a detailed set of grease and oil recommendations here (section 7, recommended lubricants): https://www.hiwin.com/pdf/lubricating_instructions.pdf
04:10 PM veegee: Yeah I always wear thick nitrile gloves
04:10 PM veegee: but just making the point
04:11 PM veegee: However if you get a pinhole leak in the glove ...
04:11 PM veegee: And you're using chlorinated brake cleaner ...
04:11 PM Thorhian: XD
04:11 PM veegee: Get ready for a night of swolen red itchy hand
04:11 PM roycroft: thorhian: i don't know how big your machine is, but if it's a bridgeport class machine you might look into adding a one-shot oiling system
04:11 PM roycroft: smaller machines can use them too, but most of the manufactured one-shot systems are for larger machines
04:12 PM veegee: Or if you're using methyl mercury, get ready for death. It goes right through the nitrile
04:12 PM Thorhian: Ah, veegee, I hope you aren't handeling any form of organic mercury compounds.
04:12 PM roycroft: you'll need a separate oil line going to each component you want to lubricate, with an adjustable valve on each line so that you can meter the correct amount to each location
04:12 PM veegee: Thorhian no, but I formally studied biology and chemistry so I'm aware of these things
04:13 PM Thorhian: Yeah roycroft, that's what I plan on doing once I get more money after getting the machine running.
04:13 PM roycroft: the manufactured one shot systems come with manifolds to handle that
04:13 PM veegee: Mine doesn't even have valves. I just pump until I see it ooze out of every slide way
04:13 PM veegee: oil is cheap and I have a 25L pail of it
04:13 PM roycroft: oil is not all that cheap
04:13 PM roycroft: and it is toxic
04:13 PM roycroft: it should not be wasted like that
04:14 PM veegee: machine tool slideway oil is not nearly as toxic as motor oil
04:14 PM roycroft: it's still toxic
04:14 PM veegee: I dispose of it correctly
04:14 PM roycroft: you're not going to successfully justify being wasteful like that
04:15 PM roycroft: you seem to like "top of the line" gear
04:15 PM veegee: It's like 20mL or so
04:15 PM roycroft: so get a proper one shot system that meters the correct amount
04:15 PM roycroft: and stop wasting
04:15 PM veegee: maybe I'm exaggerating
04:15 PM veegee: It's not a waterfall of oil
04:16 PM roycroft: i already told you that you're not going to be able to justify that kind of wastefullness
04:16 PM roycroft: but i've noted that that won't stop you from continuing to attempt to do so
04:17 PM veegee: I don't know if a tablespoon of extra oil is the end of the world
04:17 PM Thorhian: https://www.ebay.com/itm/332944913653 Is this what you are referring to (at least the pump part) roycroft?
04:17 PM veegee: I'm not justifying it, just saying I might have overstated how much extra
04:18 PM Thorhian: I have seen a valve on Marco Rep's channel that evenly distributes oil to different lines as well.
04:18 PM roycroft: yes, thorihian
04:18 PM roycroft: thorhian, sorry
04:18 PM Thorhian: You are good lol
04:19 PM veegee: Thorhian that's the one, you have to run your plumbing properly though
04:19 PM veegee: your ball screw nut may have an oil port, that's where it should go
04:19 PM Thorhian: The tab button is pretty useful for typing people's names if your IRC client does that.
04:19 PM roycroft: if your machine is not set up for a one-shot system you'll have to do some substantial modifications to set it up fro that
04:19 PM Thorhian: The nut does have an oil port.
04:19 PM veegee: pretty much every IRC client has that, since the 1600s
04:19 PM roycroft: for example, you'll need channels in the gibs for the oil
04:20 PM roycroft: and if you don't have those already you'll need to machine them
04:20 PM veegee: roycroft even the bridgeports I saw that don't have central oiling have the channels in the gibs and slideways
04:20 PM Thorhian: Gibs in the channels?
04:20 PM roycroft: which can be difficult if the machine you're modifying is the machine you need to use to modify it
04:20 PM veegee: Thorhian they're grooves that act like reservoirs
04:21 PM veegee: Thorhian see this? https://www.practicalmachinist.com/vb/attachments/f83/199729d1495798904-oil-groove-design-20160318_070134.jpg
04:21 PM Thorhian: Oh, you need to do that in linear ball bearing rails?
04:21 PM veegee: no no
04:21 PM roycroft: in the dovetailed ways on the table
04:21 PM veegee: slideways and high load areas
04:21 PM veegee: and the gibs
04:21 PM Thorhian: Yeah I have seen gibs like that in ways. I don't have ways, only linear rails.
04:21 PM roycroft: anything that moves needs to be lubed
04:21 PM roycroft: just make sure you accomodate that
04:22 PM roycroft: if you don't lube everything with the one-shot pump then it's not a one-shot pump
04:22 PM roycroft: it's a one-shot plus a bunch of extra steps system
04:22 PM Thorhian: Will do. Thankfully my Hiwin clones came with oiler nibs to attack tubes onto already.
04:22 PM roycroft: and likely not worth the effort
04:22 PM Thorhian: attach*
04:23 PM veegee: Thorhian where do you live?
04:23 PM Thorhian: US
04:23 PM veegee: ah ok
04:23 PM Thorhian: Why?
04:23 PM veegee: I was going to say if you live in Toronto, you're welcome to use my shop/machines to do what you need
04:23 PM Thorhian: Lol that would be awesome XD Can't drive to Toronto though lol.
04:23 PM roycroft: you would not get across the border
04:24 PM Thorhian: Yeah not at the moment lol
04:24 PM roycroft: unless you have a luxury yacht and turn off your collission detection system when you sneak over the border
04:24 PM Thorhian: XD
04:24 PM veegee: You can get into Canada, just not through the obvious way
04:25 PM veegee: but any other way is easy
04:25 PM roycroft: one should not do it anyway
04:25 PM roycroft: even if one finds a way
04:25 PM Thorhian: "Just because you can, doesn't mean you should."
04:26 PM veegee: Nooo don't feed him like that
04:27 PM Thorhian: I wish I could use the equipment at my university, especially with out much hand grinding I've had to do to flatten out my hot rolled steel, but it's kind of closed and I'm a CS student. They would be weary to let me near even their manual bridgeports.
04:29 PM veegee: Just dress like a greasy machinist instead of a CS geek
04:29 PM Thorhian: XD
04:30 PM veegee: You'd be surprised how many things you can sneak into just by the way you look
04:30 PM veegee: I can get into restricted areas just by wearing a high vis vest and construction hard hat
04:30 PM Thorhian: XD
04:31 PM veegee: I can also get away with murdering innocent civilians with a police officer costume
04:33 PM roycroft: i don't even know why a person would say something like that
04:33 PM Thorhian: Probably a different sense of humor.
04:34 PM Thorhian: But thanks for the advice roycroft, veegee
04:34 PM veegee: Yes just a different sense of humour based on what's going on in the USA
04:34 PM Thorhian: Until I get the oneshot pump and valves, you got any recomendations on oiling manually? How often in general?
04:35 PM veegee: Thorhian before every use, every few hours
04:35 PM veegee: Minimum once a day
04:35 PM Thorhian: Sounds good.
04:35 PM veegee: roycroft will berate you for wasting 20mL of oil, but don't worry about him. Your expensive slide rails are more important. More oil is better than less
04:37 PM veegee: Use tacky oil which sticks to the metal better. Don't use Vactra 2 like everyone says, the new Vactra 2 doesn't have tackifiers like it used to maybe a couple of decades ago
04:39 PM Rab: That kind of oil is formulated for cast iron ways. I'm not sure it's appropriate for linear rails or ballscrews.
04:40 PM veegee: That's true, but the manufacturer of my ball screws recommended using the same slide way oil
04:40 PM veegee: But maybe that's just for convenience so it can attach to the same one shot oiler system
04:41 PM veegee: Either way, I haven't had any issues nor heard of anyone with issues and all the manual vertical mills use slide way lube for their acme screws and ball screws
04:50 PM Tom_L: damn chatty here for a monday
04:50 PM XXCoder: yep
04:51 PM Thorhian: XD
04:52 PM Tom_L: and by gosh it's on topic!
05:02 PM veegee: Statutory holiday here in Canada
05:03 PM veegee: and the two generation age gap between roycroft and me always makes for an exciting edge-of-your-seat conversation
05:03 PM Tom_L: heh
05:06 PM veegee: Ya gotta love this guy's video editing: https://www.youtube.com/watch?v=otOVJv_FA8k
05:06 PM veegee: I love how he splits the metal bar in half with the chisel and hammer
05:07 PM Tom_L: what kind of metal is it?
05:09 PM Tom_L: that's bs
05:09 PM Tom_L: unless it might be carbide
05:09 PM Tom_L: but it isn't
05:13 PM Tom_L: what is that clear belt he's using?
05:13 PM Tom_L: i got no sound on this pc
05:13 PM sync: continental synchroflex profile T
05:14 PM sync: it's written right on it
05:14 PM Tom_L: i'm skipping thru
05:15 PM Tom_L: poly?
05:19 PM roycroft: age has nothing to do with the difference between your outlook on things and mine, veegee
05:19 PM roycroft: on the topic today, in fact, my view is a much "younger" one than yours
05:20 PM veegee: Tom_L it's just a joke
05:20 PM veegee: Tom_L he's not really breaking it with the chisel
05:20 PM Tom_L: i get that
05:20 PM roycroft: it's a fundamental difference on how we see the world that has nothing to do with age or anything else to which you try to attribute it
05:21 PM Tom_L: i disagree because age brings experiences the young will never have to the table
05:21 PM veegee: alright roycroft as you say :)
05:21 PM veegee: roycroft just know that I love you :)
05:21 PM roycroft: i won't disagree with that at all, tom_l
05:21 PM roycroft: and i tolerate you too, veegee
05:21 PM Tom_L: i have a switch on my monitor :)
05:22 PM roycroft: i'm saying that age is not a factor in what we were discussing earlier
05:22 PM Tom_L: i didn't read that all either
05:22 PM roycroft: it's not worth catching up on :)
05:22 PM veegee: Tom_L by clear belt you mean the timing belt?
05:23 PM Tom_L: yeah i just wondered what material it was
05:23 PM Tom_L: poly was a guess
05:24 PM veegee: Tom_L polyurethane based on a google of the label on the belt
05:25 PM veegee: Damn, I'm finding it hard to differentiate between M4 and 6NC32 threads. It's really hard to use a thread gauge for small screws
05:26 PM veegee: both M4x0.7 and 6NC32 gauges fit the threads when you only have a few teeth to engage
05:26 PM Tom_L: either one should fit a thin nut then :D
05:26 PM veegee: I ended up using the wrong one and stripping the mounting hole for the handle on my ball valve. Now I have to bore it out and tap a bigger hole
05:27 PM Tom_L: at least you'll know what you got then
05:27 PM veegee: Is there any other way, like filling it with some kind of epoxy and tapping it instead of making a larger hole?
05:27 PM veegee: It's not really a structural element, it's just for holding the handle to the ball valve, very standard
05:28 PM Thorhian: Lol I love Old Tony, even if he uses Mach for everything :)
05:28 PM veegee: I could fill it with silicon bronze with my TIG welder but I'm worried about warping the ball valve and causing it to leake
05:30 PM veegee: I also could fill it with molten Zamak 3 maybe
05:30 PM veegee: I have a random cube of Zamak 3 for casting stuff, it's great
05:33 PM Tom_L: stuff a rivet in it
07:35 PM hazzy-m: Hello
07:35 PM Tom_L: whassup hazzy-m ?
07:37 PM hazzy-m: Not much, just fixing a blown radiator hose
07:37 PM Tom_L: fun
07:37 PM Tom_L: how's probe basic lookin?
07:38 PM Tom_L: haven't been in there for a while
07:38 PM hazzy-m: Turboss and Lcvette have been plugging away at it steadily, unfortunately I've been to busy with day job to play much with it
07:45 PM CaptHindsight: hazzy-m: the Corvair?
07:46 PM hazzy-m: CaptHindsight: the vair is air cooled!!
07:46 PM CaptHindsight: why I'm asking :)
07:47 PM CaptHindsight: I'm in the middle of 12 coats of paint on a car project
07:49 PM Tom_L: what year?
07:49 PM Tom_L: i had a 62? years ago
07:53 PM CaptHindsight: Tom_L: which version?
07:54 PM Tom_L: i had 2, one for parts
07:54 PM Tom_L: iirc it was a 2dr
07:54 PM Tom_L: it was a hs project car
07:54 PM Tom_L: first car
07:54 PM CaptHindsight: never restored a Corviar myself
07:55 PM Tom_L: i rebuilt the engine and painted it
07:56 PM CaptHindsight: I mostly did Firebird/Trans-am
07:56 PM Tom_L: didn't care much for it really
07:56 PM Tom_L: my bud made the press for the bird decal on those
07:56 PM CaptHindsight: some other Pontiac's, Olds Cutlass 442, Chevy Comaro's
07:57 PM Tom_L: all hot cars
07:57 PM CaptHindsight: Camaro
07:57 PM Tom_L: a friend had a 68 camaro
07:57 PM Tom_L: nice car
07:58 PM CaptHindsight: redid some Mustangs in the late 90's, 69 and a 72 Mach 1
07:59 PM CaptHindsight: now it's mostly just keeping the daily drivers running to reach 1 million miles
08:01 PM CaptHindsight: car I'm painting now is my son's, started as a week or two strip and repaint, that turned into a complete body and suspension rebuild
08:01 PM Tom_L: sounds about right
08:01 PM CaptHindsight: all new interior as well
08:01 PM CaptHindsight: not touching the engine unless something goes wrong
08:01 PM Tom_L: mine both got new hondas this year
08:02 PM Tom_L: they've got decent jobs
08:02 PM Tom_L: i'm kinda over the repair gig unless i have to
08:02 PM CaptHindsight: https://imgur.com/a/2y99qxP had a bone yard in AZ cut off body parts for us
08:03 PM CaptHindsight: I thought it was just some surface rust
08:03 PM Tom_L: are you near the lakes?
08:03 PM CaptHindsight: and then the fenders were only $35 ea new
08:03 PM CaptHindsight: bumper $50 new etc
08:03 PM Tom_L: probably get a little more than surface rust there
08:04 PM CaptHindsight: before you know it, most of the metal is new
08:04 PM Tom_L: years back i worked in a body shop for a bit
08:04 PM CaptHindsight: 30 miles west of lake Mi
08:04 PM Tom_L: that probably doesn't help your cause
08:05 PM CaptHindsight: they salt the hell out of the roads
08:05 PM Tom_L: i cut the rear quarter out of a 40 ford and put another one back once
08:06 PM Tom_L: they used real metal then
08:06 PM CaptHindsight: pretty much all 12ga :)
08:07 PM Tom_L: replaced several kick pannels like you did there
08:07 PM Tom_L: no mig back then
08:08 PM Tom_L: torch and coathangar :)
08:08 PM Tom_L: and lotsa wet rags
08:08 PM Tom_L: the guy i worked for then actually did a little lead work on some
08:09 PM CaptHindsight: welding the rockers on this was a pain, I would have built jig to flip the car if I had planned
08:10 PM CaptHindsight: body is much less flexible now since I added some thick square tubes under
08:10 PM CaptHindsight: have 2 more cars to repaint by fall and I'm done :)
08:12 PM Tom_L: he had an old ford pickup, i forget what year but it had babbitt bearings on the rods
08:12 PM Tom_L: i recall hooking up a portable grinder to the crank and grinding a journal with it once. turning the crank with the rear wheel
08:13 PM Tom_L: haven't seen one of those in years
08:15 PM Tom_L: http://www.rtsalesinc.com/web_quotes_english/Crankshaft_Camshaft_Equipment/Winona_In-The-Blok_Portable_Crankshaft_Grinder_STOCK_0090.htm
08:15 PM Tom_L: similar
08:15 PM Tom_L: i think the one he had was a sunnen
08:18 PM Tom_L: CaptHindsight, you use epoxy or something else?
08:18 PM Tom_L: dunno what they use nowdays i'm sure it's partially water borne
08:19 PM Tom_L: due to the coats i'd guess laquer
08:19 PM CaptHindsight: epoxy primer on bare metal, then urethane filler primmer, urethane base coats, some custom urethane color, urethane clear clear clear
08:20 PM CaptHindsight: I used to use lacquer
08:20 PM CaptHindsight: was original GM paint
08:20 PM CaptHindsight: Ford was enamel
08:21 PM Tom_L: urethane use a catalist?
08:21 PM CaptHindsight: so it can be 6-12 coats depending on effects
08:21 PM CaptHindsight: yes, isocyanate cured urethanes
08:21 PM CaptHindsight: I wear a space suit
08:21 PM Tom_L: :)
08:22 PM CaptHindsight: but each layer is usually cure to sand in 1 hour
08:23 PM CaptHindsight: so only take a couple of days to get to final clear, then maybe 1-2 more days of sand and polish
08:23 PM Tom_L: do you have to recoat before they're fully cured on those urethanes?
08:24 PM CaptHindsight: no, the epoxy primer is good for 24 hours or you have to hit it with #400 before the next coat
08:25 PM CaptHindsight: color base coat is just flash between coats
08:25 PM CaptHindsight: so ~10 min
08:25 PM CaptHindsight: clears are similar
08:25 PM CaptHindsight: but I have some effects going on with 3d and colored particles
08:25 PM roycroft: another milestone today
08:26 PM roycroft: i machined some parts to final dimensions
08:26 PM roycroft: 52 hours into the project
08:26 PM CaptHindsight: wood?
08:26 PM roycroft: yes
08:27 PM roycroft: my workbench project
08:27 PM roycroft: design time is not counted in that 52 hours
08:27 PM CaptHindsight: do you save the dust and make your own composites?
08:27 PM roycroft: there's probably at least 100 hours of design time
08:27 PM roycroft: i'm not particularly "saving" the shavings
08:27 PM roycroft: but i've mulched everything i can mulch on my property
08:28 PM roycroft: and i still have five big bags full of shavings
08:28 PM CaptHindsight: roycroft: are you still having hot weather there? We didn't crack 70F today
08:28 PM roycroft: big as in leaf bag size
08:28 PM roycroft: it only got up to 29 or so today
08:28 PM roycroft: it's cooled off quite a bit, but it's still pretty warm
08:28 PM roycroft: it's actually 29 right now
08:28 PM CaptHindsight: cool this week then back to 90F-ish 30C
08:28 PM roycroft: and that was the high for the day
08:29 PM roycroft: also the average high for the day
08:29 PM roycroft: we'll be down to the mid 20s by thursday, with a chance of rain, and then back up into the low- to mid-30s by week's end
08:29 PM jdh: down to 80F here now. but, there is also a hurricane
08:30 PM roycroft: humidity is 32% here
08:30 PM roycroft: in the southeast it's like 98% right now
08:30 PM CaptHindsight: Tom_L: the problem i have is having many jars of special effects particles, which to use?
08:30 PM roycroft: i also glued up my dog hole strip today
08:30 PM roycroft: which is the trickiest glueup of the whole project
08:30 PM roycroft: but i think it is going to turn out great
08:31 PM roycroft: at least i hope so :)
08:31 PM roycroft: one more glueup after the dog hole strip and then i can dimension all the rest of the parts to their final dimensions
08:32 PM roycroft: i shall probably be able to start joinery in a couple weeks at most
08:32 PM flyback: tom
08:32 PM flyback: do you still have the web page with the mediatek hack
08:33 PM Tom_L: yup
08:34 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/mtkflash/flash_howto_index.php
08:35 PM flyback: thx
08:38 PM jymmmm: Tom_L: I wouldnt even boter with LCD today... https://www.amazon.com/IZOKEE-Display-SSD1306-Raspberry-White-IIC/dp/B076PDVFQD
08:39 PM Tom_L: that was likely 10yrs or so ago
08:39 PM Tom_L: oled wasn't a thing yet
08:42 PM jymmmm: Tom_L: https://youtu.be/oyMzxBGFXcM?t=558
08:42 PM jymmmm: Tom_L: I know, I have a few collecting dust brand new in the package
08:54 PM snakedGT is now known as snaked
08:56 PM CaptHindsight: what to do with new old stock of 10GB hard drives?
08:57 PM CaptHindsight: 1999
08:57 PM Tom_L: rue melts the aluminum down and makes new stuff
08:57 PM XXCoder: build a retro computer system
08:57 PM Tom_L: raid?
08:57 PM Thorhian: Lol I always forget that harddrives are basically slabs of aluminum.
08:58 PM Thorhian: You can use the spindle motors in them as fancy rotary encoders lol
08:58 PM flyback: acrually
08:58 PM flyback: older hd's like that
08:58 PM flyback: have the best magnets
08:58 PM flyback: also they are probably ball beasring not fluid
08:58 PM flyback: which is better for making smal wind turbines
08:59 PM * flyback is trying to pull data from 500MB hd's even
08:59 PM flyback: how is rue these days
08:59 PM flyback: he's so weird I can't tell if he's ok or not
08:59 PM CaptHindsight: do kids today see CRT's the same as a steam engine?
09:00 PM Thorhian: Whether that is an apt comparison or not, I hate hauling CRT screens.
09:00 PM flyback: I still have one
09:00 PM flyback: 28 inch
09:00 PM flyback: atsc tuner
09:01 PM _unreal_: new spindle almost done with the refit https://cdn.discordapp.com/attachments/717411349541683212/740024270285045821/20200803_215147.jpg
09:01 PM CaptHindsight: i knocked over one of my first LCD monitors, still works but there a crack and funky colors
09:01 PM flyback: nice
09:01 PM flyback: its in my shed I am sick of paying $75/month for 2 hrs
09:01 PM flyback: for momstly crap
09:01 PM flyback: so it's going soon along with the apple IIc, etc
09:01 PM flyback: hx20
09:02 PM flyback: buanh of random shit
09:02 PM Thorhian: That's awesome unreal. The whole thing still scares me though.
09:02 PM flyback: 2 yrs
09:02 PM _unreal_: scares?
09:02 PM _unreal_: dont forget I used the MILL to make its new parts
09:03 PM _unreal_: it made its own upgrades
09:03 PM CaptHindsight: composite cnc router
09:03 PM norias: i wonder how hard making an HSK spindle would be
09:03 PM flyback: heh
09:03 PM norias: like HSK40
09:03 PM Thorhian: That is definitely cool. I've done that with a printer which might be easier.
09:03 PM flyback: I should give unreal this ibm servi
09:03 PM flyback: they are like $150
09:04 PM flyback: I imght have friend the optical encoder
09:04 PM flyback: but it's a big ass dc motor
09:04 PM flyback: looks like a car starter
09:04 PM flyback: from a high speed mainframe printer
09:04 PM Thorhian: norias: That would be awesome. Personally I wouldn't mind making a beefy CNC Lathe to make an HSK spindle and the tool holders.
09:04 PM _unreal_: one thing is for damn sure THAT Z IS WAYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY more rigid
09:05 PM _unreal_: and by design all directions of FLEX have been reduced
09:06 PM norias: Thorhian: i kinda want to make a mill, but i kinda don't want to make one unless it has an HSK spindle
09:06 PM norias: i would definitely not make the holders
09:06 PM norias: but freaking HSK spindles are expensive
09:06 PM Thorhian: That's how I felt when I watched Marco's mill series initially, then I realized HSK is big bucks. I settled for BT30.
09:06 PM norias: ( unless someone knows a cheap source )
09:07 PM norias: marco's mill?
09:07 PM Thorhian: Marco Reps
09:07 PM norias: dunno what that is
09:07 PM Thorhian: https://youtu.be/vB_FvkllLPc
09:07 PM Thorhian: Youtuber, did a whole CNC series.
09:08 PM norias: neat
09:08 PM Thorhian: He got Mechatron to sponsor him, so he scored an HSK20 ATC spindle.
09:08 PM CaptHindsight: oh damn, down to $600 ea or best https://www.ebay.com/itm/1979-Matsuura-MC-500V-CNC-Mill-with-YASNAC-2000G-control/283531836872
09:08 PM norias: i'm not a fan of the bridge design
09:08 PM Thorhian: Good german engineering, wicked expensive.
09:08 PM flyback: https://www.ebay.com/itm/1053172-IBM-Motor-Assm-Carrier-for-IBM-4230-printer/331189696873?hash=item4d1c71b969:g:LF8AAOxyThVTX7b3
09:08 PM norias: i feel like, if i were to do a machine
09:08 PM CaptHindsight: it's at scrap price now
09:08 PM norias: i'd do a horizontal spindle
09:08 PM norias: with HSK
09:08 PM norias: i have a tool changer concept i think is fun
09:09 PM Thorhian: I have seen horizontal machines. What is the advantage in doing that?
09:09 PM norias: rigidity
09:09 PM norias: chip management
09:10 PM norias: you put a lot of mass in the structural loop
09:10 PM norias: instead of the wee little column on a vertical
09:10 PM Thorhian: I've always been enamored by 5 axis kern machines and DMG Mori's massive 5-axis machines. That makes sense though.
09:10 PM norias: yeah
09:11 PM norias: someone somewhere had a really unique design for a horizontal 5 axis
09:11 PM norias: wish i could remember
09:11 PM norias: i feel like making a machine is a distraction for me, though
09:11 PM CaptHindsight: I prefer making to using
09:11 PM norias: i really just want to focus on unattended machining
09:12 PM CaptHindsight: using to me is just crank
09:12 PM Thorhian: Journey before Destination.
09:13 PM norias: at the same time, i feel like i should make a machine just to do it
09:13 PM norias: oh well
09:13 PM Thorhian: I mean, I bet you would learn a ton lol. Just don't let it destroy your life.
09:13 PM norias: i'd be tempted to a mixed dura-bar, steel weldment, epoxy granite base
09:14 PM Thorhian: I find Kern's method interesting. Aluminum and Epoxy Granite. Easy for temperature control, which is definitely one of their selling points for their crazy tolerances.
09:14 PM norias: i'm not touching aluminum with a ten foot pole
09:15 PM norias: dental machines?
09:16 PM Thorhian: *Shrug* The epoxy granite does all of the vibration dampening, so I definitely see why they do it.
09:16 PM norias: yeah, hmm.
09:16 PM norias: that is an interesting point
09:16 PM Thorhian: 5 axis kern mills? Dental Machines? Nah man.
09:17 PM XXCoder: from what I understand few size tiers of gravel inside it, from powder to rocks would make it super effective on absorbing vibrations
09:17 PM Thorhian: They advertise sub micron tolerances.
09:17 PM _unreal_: I CAN NOT wait to test my achine when I get it all wired up
09:17 PM _unreal_: one of the first parts I have to make is a new dust shoe
09:18 PM Thorhian: John Grimso bought a kern mill for his knife business. He even went on a tour at Kern in Germany: https://www.youtube.com/watch?v=OLiTHuVI0mY
09:19 PM norias: Thorhian: thanks for turning me on to this. interesting machines.
09:20 PM norias: oh, hydrostatic bearings on the one machine
09:21 PM norias: those can be a little maintenance heavy at times
09:21 PM norias: at least, the ones on the grinders the one place i worked were
09:23 PM norias: oh these are neat machines
09:23 PM Thorhian: Where are you looking?
09:24 PM norias: i'm looking at the pyramid nano right now
09:25 PM norias: 210 tools on the micro HD
09:25 PM norias: now we're talking
09:25 PM Thorhian: XD
09:26 PM Thorhian: Plus they have machines with pallet changing systems that are pretty cool too IMO.
09:26 PM unterhaus: 28 players on the Rutgers football team have covid
09:26 PM unterhaus: I'm pretty sure I'm going to die
09:26 PM Thorhian: Why are you going to die?
09:26 PM unterhaus: because of the virus
09:27 PM unterhaus: students aren't here yet, and it's going around
09:27 PM Thorhian: Ah, so your in a college town?
09:27 PM unterhaus: yes
09:27 PM unterhaus: university park, where Penn State is
09:27 PM Thorhian: Fun.
09:28 PM norias: unterhaus: i'm in pittsburgh
09:28 PM XXCoder: if you has condition that increases chance of death, maybe change to better type of mask where it can actually yourself and not just others
09:28 PM Thorhian: N95 or better would be good.
09:28 PM unterhaus: most better masks have unfiltered exhaust
09:29 PM unterhaus: I saw a guy wearing a n99 mask the other day, maybe I should follow suit
09:29 PM XXCoder: or postive pressure head mask, like for dealing with bad air like painting
09:29 PM XXCoder: though some limit on hours
09:29 PM unterhaus: I have gas masks :)
09:30 PM unterhaus: I would feel bad about unfiltered exhaust though
09:30 PM XXCoder: yeah dont use those
09:30 PM unterhaus: actually, he was wearing a p100 mask
09:31 PM unterhaus: I don't think you can get filters
09:31 PM Thorhian: Where I live n95's are fairly plentiful, which has been nice since I have had to do a lot of grinding for mill steel.
09:31 PM norias: unterhaus: i don't think unflitered exhaust is as bad as you think
09:31 PM unterhaus: it's not bad for me, others, not so mucj
09:31 PM unterhaus: much
09:32 PM Tom_L: first test cut: http://tom-itx.no-ip.biz:81/~webpage/cnc/rotary/RotaryTest2.jpg
09:32 PM XXCoder: whoa cut by craftman wrench
09:32 PM Tom_L: broach :)
09:32 PM XXCoder: heh
09:32 PM Thorhian: XD
09:32 PM XXCoder: anyway looks fine?
09:33 PM Tom_L: fits good
09:33 PM norias: unterhaus: i question how bad. The exhaust port is still going to disrupt flow
09:33 PM robotustra: https://imgur.com/a/Jy1VFXf
09:33 PM Tom_L: kinda fun doing manual on a cnc for a change
09:34 PM XXCoder: first 3: protection of self. 4th: protection of others in case of asypomtic infection
09:34 PM XXCoder: not remotely same
09:35 PM unterhaus: mproas. I imagine that's true. I should go test it
09:36 PM unterhaus: wouldn't be hard to rig up a filter
09:37 PM unterhaus: sad thing is, if we had been wearing crummy masks, it would be handled by now. But we weren't wearing them
09:38 PM XXCoder: yep. i got masks as early as possible and wore em for while now
09:38 PM XXCoder: because i cough daily for last 7 years. how do I know?
09:39 PM XXCoder: loss of taste and smell? i never smelled anything in my life, and that affects taste too
09:39 PM Thorhian: My family has been fairly diligent even though we live in a really low risk area compared to a lot of other places. I'd rather not kill my mom or grandma who both have heart conditions.
09:41 PM unterhaus: there was a big beach event at a lake called Butte des Morts in Wisconsin. Mountain of dead. Seems appropriate
09:42 PM unterhaus: who names a lake/town that?
09:44 PM unterhaus: Tom_L, do you have a picture of your rotary axis setup?
09:44 PM Tom_L: i posted earlier
09:44 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/rotary/Rotary1.jpg
09:45 PM XXCoder: unterhaus: out in butt end of nowhere so names good too lol
09:46 PM Thorhian: Lol norias are you still analyzing the different kern machines?
09:47 PM unterhaus: It's a little south of Green Bay, so I'm surprised I never heard of it
09:47 PM unterhaus: I was going to green bay on the 13th, but canceled. Looking like it probably was a good idea
09:50 PM XXCoder: theres big number of cases over and over after events
09:50 PM XXCoder: hundreds of people got covid by daycamp for example
09:50 PM XXCoder: few hopspitalized
09:51 PM _unreal_: XXCoder, getting closer https://cdn.discordapp.com/attachments/717411349541683212/740024270285045821/20200803_215147.jpg
09:51 PM Thorhian: AKA, social distancing is still a good idea.
09:51 PM _unreal_: bull shit
09:51 PM jymmmm: XXCoder: daycamp?
09:51 PM _unreal_: Thorhian, my entire background is nursing and medical
09:51 PM Tom_L: _unreal_, did you get the link i posted to that analog mesa board?
09:52 PM _unreal_: ono
09:52 PM _unreal_: on
09:52 PM XXCoder: yeah bunch of adults and many teenagers go camp for one day and night and go home
09:52 PM _unreal_: arg
09:52 PM _unreal_: no
09:52 PM XXCoder: yet over 400 got covid
09:52 PM XXCoder: insane.
09:52 PM jymmmm: XXCoder: They must have been licking the same doorknobs
09:53 PM XXCoder: or each opther
09:53 PM _unreal_: covid is a farce..... over 1k people die every day from flu, over 3k peole die every day from TB
09:53 PM _unreal_: over 1k die every day from rotovirus. and 500 a day with norovirus
09:53 PM _unreal_: covid 50 a day

09:55 PM Tom_L: should work fine
09:55 PM Tom_L: ok
09:55 PM Tom_L: i didn't know if it had analog out
09:55 PM _unreal_: testing it when I get everything wired up
09:56 PM Tom_L: mine has that circuit built on it as well
09:56 PM _unreal_: only things left at this point are limit switches, and spindle bldc wire
09:57 PM _unreal_: my motion controller says spindle speed control 0-10v and the motor controller says 0-10v so I'm guessing it should be compatable
09:58 PM Tom_L: yup
09:58 PM Tom_L: what controller are you using?
09:58 PM _unreal_: I just posted
09:58 PM _unreal_: its a planet cnc controller
09:58 PM Tom_L: oh
09:58 PM Tom_L: ok
09:58 PM _unreal_: its a china knock off but works great
09:59 PM _unreal_: spindle is SOOOOOOO damn rigid now
09:59 PM Tom_L: nice ehh?
10:00 PM _unreal_: so far
10:00 PM _unreal_: before I had so much flex
10:00 PM _unreal_: it will be interesting to see what milling aluminum is like
10:01 PM _unreal_: I also have now switched all axis from metal nuts to HDPE nuts
10:01 PM Thorhian: Milling my first aluminum chips was quite exciting for me :D
10:01 PM _unreal_: my Y has been running on an HDPE nut from the start
10:02 PM _unreal_: btw florida/CDC got caught posting fake numbers https://www.sun-sentinel.com/coronavirus/fl-ne-coronavirus-florida-children-rate-20200725-woaowotttrbdxc4cqqshttqkje-story.html?fbclid=IwAR3Up5c4vOWIHyTANcw0ZOXul6XjCH_eXdGIlxwL2V3I7eLthHdIxB22I1M

10:02 PM Tom_L: it's been a good day
10:03 PM _unreal_: it will be a good day when I get all my stocks free finally
10:03 PM Thorhian: Gonna have to agree with Tom_L. Keep things on topic?
10:03 PM _unreal_: M'fer asswhole managers at work really screwed up my breaks intentionally to screw up my stocks
10:03 PM _unreal_: thought it was funny
10:04 PM _unreal_: at this point when I get a big score I'M DONE, I'll be quitting and doing stocks and starting my own company up again
10:05 PM _unreal_: had I been able to play KODAK last week I'd be sitting EASY on $30k
10:05 PM * roycroft thinks _unreal_ may be related to veegee :)
10:05 PM Thorhian: XD
10:06 PM _unreal_: I am a euro mut

10:13 PM CaptHindsight: https://www.reddit.com/r/3Dprinting/comments/i1htef/my_take_on_the_2020_dumpster/
10:14 PM XXCoder: nice
10:23 PM CaptHindsight: anyone work with injection molding much?
10:25 PM Tom_L: i wish kenneth maxon's site was still up, he made an injection mold machine
10:25 PM Tom_L: top notch
10:25 PM CaptHindsight: also down https://www.collidertech.com
10:26 PM Tom_L: http://www.seattlerobotics.org/encoder/199703/mold_art/molds.htm
10:26 PM Tom_L: might get you closer
10:26 PM CaptHindsight: SLA and injection mold in one machine, stupid
10:26 PM Tom_L: he molded those track treads
10:26 PM XXCoder: you know why site was remobved?
10:27 PM Tom_L: no

10:29 PM Tom_L: he had pics of it all
10:30 PM roycroft: a bridgeport is not very heavy
10:30 PM CaptHindsight: https://www.youtube.com/watch?v=iOaDs0MBalM
10:30 PM roycroft: but depending on how much he had to boom it out it might have required a decent size crane
10:31 PM Tom_L: it was large
10:31 PM Tom_L: he didn't do anything halfway
10:31 PM CaptHindsight: i used a 50-ton crane to unload the matsuura
10:32 PM CaptHindsight: the operator swung it a bit to get it just passed the door line since the crane could not reach inside
10:32 PM _unreal_: my father use to deal with injection molding of plastics
10:33 PM _unreal_: Tom_L, look it up on archive.org
