02:04 AM Deejay: moin
05:49 AM Tom_L: morning
05:52 AM jthornton: morning
09:33 AM Loetmichel: hmm... just drove 250km to my sister... note: driving 140mph in a slight drizzele an then suddenly there is a wall of water: bown trousers moment... MAAN that downpour came unexpected... couldnt see a THING suddenly.. :-(
10:23 AM * jthornton tries to figure out how to get a file into octoprint... drag and drop doesn't work for some reason
10:31 AM jthornton: hmm mighty sensitive where you drop it
11:03 AM Elmo40: yeah. i dont like it myself.
11:03 AM Elmo40: i always use the UPLOAD button.
11:04 AM Elmo40: the entire UI needs a revamp. I have seen many improved designs that i wouldnt mind implementing. the slider to change speed or extrusion rate is way too sensitive and tiny.
11:04 AM Elmo40: plus, there is no feedback for any of the values. that is one of the reasons why i want to use LinuxCNC for 3D printing.
11:17 AM jthornton: lol I thought the upload button was to upload to the printer but I see now it uploads to the Rpi
11:18 AM jthornton: I guess I need to wait till Monday so I can connect the Rpi to the printer to do much more
11:51 AM jthornton: hmm got a usb camera working lol
11:52 AM Loetmichel: :-)
12:26 PM JT-Shop: lol got the Rpi with octopi connected to my old printer so I can test more stuff
12:28 PM Elmo40: i find the raspi's ribbon camera to be slow.
12:35 PM JT-Shop: be nice if it had a MDI
12:42 PM Loetmichel: it IS slow
12:42 PM Loetmichel: and low resolution
12:43 PM Loetmichel: one of the resons why i use logitech C270s on my printers
12:44 PM Loetmichel: (also because i use an I5 PC with repetier server for both printers, eventually for up to 6 printers
12:50 PM JT-Shop: I might just revive my old printer as well
01:28 PM JT-Shop: all right the extruder fan is working now... now to clear the extruder out...
02:16 PM skunkworks: jym: the rigol works..
02:18 PM jym: skunkworks: you got it?
02:19 PM skunkworks: yes
02:19 PM skunkworks: I found the codes
02:21 PM jym: awesome =)
02:21 PM skunkworks: jym: took way to long to figure out how to turn off the overlay..
02:21 PM skunkworks: felt stupid ;)
02:23 PM jym: skunkworks: Nah, it's all good. new UI, gets weirds sometimes
02:25 PM skunkworks: measured the 1khz test sig and then 120v :)
02:26 PM skunkworks: took 2 tries for the unlock code.. I entered the serial number wrong.
02:34 PM jym: Glad it didn't lock up on you
02:37 PM JT-Shop: woopee the printer is going again
02:48 PM skunkworks: jym: yes.. Must give you a couple tries
02:49 PM JT-Shop: what are you working on?
02:50 PM skunkworks: Got a rigon osciliscope
02:50 PM skunkworks: rigol
02:50 PM skunkworks: finally.
02:51 PM JT-Shop: nice
02:52 PM JT-Shop: it's unreal, I gave up on this aliexpress printer a while back... got recent cura, plugged a rpi3 with octoprint and it just works now...
02:55 PM skunkworks: heh - cool
02:55 PM skunkworks: I am still running the monoprice mini
02:55 PM skunkworks: I have had bad luck with the latest cura
02:55 PM skunkworks: I have been using 3 something
02:56 PM JT-Shop: I'm not sure what version I got this morning
02:56 PM JT-Shop: what issues did you have with the latest cura?
03:06 PM Elmo40: latest version cleans up a bunch of hiccups from the last 2 updates.
03:07 PM Elmo40: but there are still a million things i don't like about it...
03:07 PM Elmo40: my main issue is positioning items on the bed. i want to input the angle, not use the mouse and spin it around.
03:08 PM Elmo40: i think they believe users are basic creatures that don't need/want so many options.
03:21 PM skunkworks: JT-Shop: well - it just seems to print certain areas thinner than it should.
03:21 PM skunkworks: almost like the tip is pluggin
03:33 PM JT-Shop: hmm
03:33 PM JT-Shop: yea using the mouse to position something is a joke
03:34 PM CaptHindsight: I forget who the sewing machine expert is in here
03:34 PM CaptHindsight: please stand up
03:36 PM CaptHindsight: https://www.youtube.com/watch?v=ouVPreXskTE
03:36 PM CaptHindsight: https://www.youtube.com/watch?v=TpPBYGLj76U
03:37 PM CaptHindsight: https://youtu.be/S2mO718uofo?t=12
03:46 PM micges: CaptHindsight: I've done quilting machines, does that count?
03:49 PM skunkworks: JT-Shop: you have a comma after openbox http://gnipsel.com/linuxcnc/uspace/rpi4-ob.html
03:50 PM skunkworks: micges: how goes it?
03:51 PM micges: skunkworks: ups and downs
03:51 PM micges: but pretty good
03:54 PM skunkworks: goodish :)
03:55 PM micges: skunkworks: and you?
04:00 PM Deejay: gn8
04:01 PM JT-Shop: skunkworks: thanks
04:01 PM JT-Shop: hi micges
04:01 PM * JT-Shop goes back to mowing grass
04:02 PM micges: JT-Shop: hi
04:07 PM * jym read that as " JT-Shop goes back to growing the grass" (aka napping )
04:07 PM jym: skunkworks: how's the scope coming along?
04:07 PM jym: skunkworks: How did you setup to read 120VAC?
04:09 PM likevinyl is now known as Guest83188
04:20 PM skunkworks: jym: umm - X10 probe just hooked to the hot.. hit auto button :)
04:20 PM skunkworks: rms seemed spot on too
04:20 PM skunkworks: imagine
04:20 PM skunkworks: ;)
04:20 PM skunkworks: micges: same
04:21 PM jym: skunkworks: It came with switchable probes?
04:23 PM skunkworks: yes - 4
04:23 PM skunkworks: suprised me...
04:26 PM skunkworks: jym: http://electronicsam.com/images/greenmachine/IMG_20190907_161736.jpg
04:28 PM Tom_L: skunkworks what are the unlock codes for?
04:30 PM skunkworks: quite a few things.. the main being it goes from a 50mhz scope to 100mhz
04:30 PM Tom_L: i wondered which one you got and whether you'd try the 50Mhz one
04:31 PM skunkworks: pretty inexpensive for what you seem to get
04:31 PM JT-Shop: neat
04:31 PM Tom_L: https://nyctomachia.wordpress.com/2018/09/02/riglol-unlock-extra-features-on-rigol-oscilloscopes/
04:32 PM skunkworks: JT-Shop: installed the realtime image that andy posted in your thread - now following your directions.
04:33 PM JT-Shop: if you spot any typos let me know
04:33 PM JT-Shop: now what was the one from a while ago...
04:45 PM CaptHindsight: micges: a few months back you told me which older machines are worth buying
04:45 PM CaptHindsight: all/mostly metal
04:45 PM micges: CaptHindsight: sorry, that wansn't me
04:46 PM CaptHindsight: ok, sorry it was a familiar name but forgot exactly who
04:48 PM CaptHindsight: looking for a machine to modify that is a good start
04:49 PM micges: start for what?
04:49 PM CaptHindsight: modified sewing machine
04:50 PM CaptHindsight: https://openbuilds.com/builds/embroidery-machine-with-xy-belt-and-pinion-drive.691/
04:53 PM micges: CaptHindsight: I did just that one: https://www.youtube.com/watch?v=i5BS3v9BsUQ
04:53 PM CaptHindsight: separate the bobbin from the needle and use HAL to sync motion vs all the gearing and levers
04:54 PM XXCoder: https://www.youtube.com/watch?v=U70BWviOXEQ I like that hes being careful with restoration due to all that lead.
04:55 PM XXCoder: he also try his best to respect orginality
04:56 PM CaptHindsight: where in the USA do you guys find old mechanisims and machines (not cnc)?
04:57 PM CaptHindsight: bottle corkers, pre-cnc automation etc
04:57 PM XXCoder: man I like his tool (like cresecent, but flat) but its so expensive
04:57 PM XXCoder: good question capt
04:58 PM CaptHindsight: craislits, ebay, fle-markets
04:58 PM XXCoder: dumps
04:58 PM CaptHindsight: yeah
04:58 PM XXCoder: maybe evebn metal scrap if it havent been too pulled apart
04:58 PM CaptHindsight: around here scrap doesn't stay around too long
04:58 PM CaptHindsight: maybe days
05:29 PM jym: skunkworks: Sweeeet =)
05:35 PM jym: skunkworks: I am curious to the USB port capabilites
05:45 PM jthornton: skunkworks, I'm using Cura 4.2.1
05:47 PM skunkworks: let me know how it prints for you
05:48 PM skunkworks: jym: do you have one?
05:48 PM jthornton: so far using the crap filament that came with the aliexpress printer it prints good, I've not tried my good stuff
05:49 PM skunkworks: cool
05:54 PM XXCoder: atomic?
05:56 PM JT-Shop: yea the good stuff is atomic
05:57 PM XXCoder: most of mine is
05:57 PM XXCoder: still waiting for part from aliexpress to hopefully repair my crap printer
05:58 PM jym: skunkworks: No, But I've been thinking about
05:58 PM JT-Shop: need to figure out what size nozzle I have...
05:58 PM JT-Shop: XXCoder: what broke on yours?
05:58 PM XXCoder: the belt end torsoner
05:58 PM JT-Shop: for the Y axis?
05:59 PM XXCoder: yeah
06:00 PM JT-Shop: I made a new yolk for mine out of aluminum the printed part was crap
06:00 PM XXCoder: mine was overly brittle
06:01 PM XXCoder: too small and high stress for printed part
06:05 PM JT-Shop: you can't make one at work on lunch break?
06:05 PM XXCoder: mill one out? nah its cheaper to just buy
06:06 PM XXCoder: work machines is RARELY free too
06:06 PM JT-Shop: probably take 15 minutes on a manual to make that part
06:08 PM JT-Shop: https://imagebin.ca/v/4uF9MZccs8LS
06:09 PM JT-Shop: yuck what a crappy photo
06:09 PM XXCoder: interesting
06:19 PM JT-Shop: hmm found a pack of nozzles marked 20, 30, 40, 50, 60 lol still don't know what I have installed
06:21 PM JT-Shop: I think I have the 0.4mm nozzle installed
06:23 PM XXCoder: some nozzle designs have dot pattern
06:23 PM XXCoder: that tells you what sie it is
06:24 PM Tom_L: it's morse code
06:24 PM Tom_L: or braile
06:25 PM XXCoder: nah just number of dots
06:25 PM XXCoder: zero to 4 I think
06:26 PM Tom_L: how was the trip JT-Shop?
06:29 PM jthornton: good, got run out of the Outer Banks a few days early but we had fun on the way back
06:29 PM jthornton: got to see 3 black bear cubs on the side of the Blue Ridge Parkway playing in the sun
06:36 PM jthornton: weird I get different g code between the aliexpress and the ender 3 but can't find out why
06:36 PM XXCoder: aliexpress huh
06:37 PM XXCoder: oh aliexpress el cheapo machine
06:37 PM jthornton: I wonder if it is the print xy size that results in a different outcome
06:37 PM jthornton: yea same one you have iirc
06:38 PM jthornton: nope
06:38 PM jthornton: start and end g code is very different
06:39 PM XXCoder: they tend tp have header and tail settings
06:39 PM XXCoder: some machines finish by homing x and y again
06:39 PM XXCoder: some dont, etc
06:41 PM XXCoder: heres my old printer tail settings for examplke
06:41 PM XXCoder: G4 2000; pause 2 seconds
06:41 PM XXCoder: G28 X Y;
06:41 PM XXCoder: G1 Y200 F5000.
06:41 PM XXCoder: M104 S0 ; turn off temperature
06:41 PM XXCoder: M84 ; disable motors
06:42 PM jthornton: the ender 3 does a ring around all the parts and the aliexpress configuration does a pad around each part in cura
06:42 PM jthornton: dunno
06:42 PM XXCoder: basically it waits 2 seconds due to some issue i forgot what, homes x and y then moves y to other side turn stuff off
06:43 PM XXCoder: youre using builtin slicer?
06:43 PM jthornton: I smell some rabbit food being prepared, must be dinner time
06:43 PM jthornton: no using cura on it's own
06:44 PM jthornton: ah I think I found the settings
06:44 PM XXCoder: do you have aliexpress and ender settings?
06:44 PM XXCoder: suggest make backup before you alter stuff
06:45 PM jthornton: the ender was in cura I just did a generic for the aliexpress
06:45 PM XXCoder: bah youre lucky. I had to alter so many settings to make my alipexpress one work
06:45 PM XXCoder: extruder settings was way off lol
07:44 PM skunkworks: auto sure is nice... never had a scope with it
07:46 PM Tom_L: can be dangerous once you get used to it
07:53 PM skunkworks: like auto-tuning servos...
07:54 PM jdh: does servo auto-tuning ever work?
08:11 PM XXCoder: yo
08:11 PM Tom_L: yoyo
08:12 PM BGPNeighbored: can't send to my left foot
08:12 PM XXCoder: BGPNeighbored: you alive?
08:12 PM BGPNeighbored: there we go
08:13 PM BGPNeighbored: haven't been on freenode in a few years, i guess
08:13 PM BGPNeighbored: anyone around that knows anything about using a ramps 1.4 in an xy table?
08:15 PM XXCoder: need more specific question. :)
08:17 PM Tom_L: you'd probably just set up the first 2 axis in the config
08:18 PM BGPNeighbored: I have it set up, i'm reading end stops/traveling accurately, what i'm stuck on is a software toolchain to go from an airfoil .dat to a toolpath that helixes inward to the geometry defined by those points
08:19 PM BGPNeighbored: so, kinda like the inverse of what Fusion360 might give you for a given pocket
08:19 PM Tom_L: if it's an airfoil you're gonna need more than just x and y
08:20 PM Tom_L: so more a software problem than a ramps problem
08:21 PM BGPNeighbored: well, i have a component built in fusion360 with the right chord, but I'm having trouble relating the videos I'm finding to my application
08:23 PM Tom_L: where'd the .dat file come from?
08:23 PM gregcnc: .dat is just coordinates
08:24 PM gregcnc: used to make a spline or similar
08:24 PM BGPNeighbored: there's a fusion360 script that creates a spline
08:25 PM BGPNeighbored: but I can't just go from that to an .svg, can I?
08:25 PM BGPNeighbored: well, no, that'd only give me the finishing pass, we'd need the rest of the passes
08:26 PM gregcnc: aren't you using fusion to generate the code?
08:27 PM BGPNeighbored: *burp* I've been watching youtube videos and drinking beer for hours, and I feel like I'm pretty well stuck in fusion. is there a set of search terms you'd recommend?
08:28 PM gregcnc: to do what?
08:28 PM BGPNeighbored: make f360 do the thing I need it to
08:29 PM gregcnc: first find a post processor compatible with whatever ramps is.
08:29 PM Tom_L: are you trying to mill a cavity or cut an airfoil from a block?
08:29 PM gregcnc: then, learn the CAM part of F360
08:29 PM BGPNeighbored: Tom, the latter.
08:30 PM Tom_L: if all you have is the final pass you need to decide which way you want to go from it
08:30 PM Tom_L: up or down
08:30 PM BGPNeighbored: concentrically
08:30 PM BGPNeighbored: there's not a Z axis in meatspace for my rig
08:31 PM Tom_L: i don't know how fusion 360 works so i can't help with that part but it should be able to spit out gcode for you
08:31 PM gregcnc: no z? what kind of machine is this?
08:31 PM BGPNeighbored: it's an infernal hodgepodge i built in my living room
08:31 PM Tom_L: heh good luck cutting a 3d airfoil with a 2d machine
08:31 PM gregcnc: ok, but fundamentally what type?
08:32 PM BGPNeighbored: tom: making 3D airfoils with 2D machines is a very well understood science
08:33 PM BGPNeighbored: it uses a ramps 1.4 board, and steppers for x and y. it's running marlin firmware atm, but if there's something better, by all means
08:33 PM gregcnc: https://openbuilds.com/builds/phlatprinter-mk-3.5207/
08:34 PM BGPNeighbored: fundamentally similar, mine's not made out of foamcore though
08:34 PM BGPNeighbored: well, *entirely* out of foamcore
08:34 PM gregcnc: i knoiw nothing about that, except it's been aroudn a while and sounds 2.5D
08:35 PM gregcnc: i'd look around for examples of what you want to do with the ramps thing and see how others got there
08:37 PM Rab: BGPNeighbored, so you have a contoured model and you need to slice it into 2D cutting planes?
08:40 PM BGPNeighbored: Rab: I have those, I need a way to take my squarish stock and mill it down to the finished profile
08:41 PM gregcnc: in other words generate code to cut 2d shapes, but lacks a post and CAM experience
08:42 PM Tom_L: f360 should be able to generate a layered cut file
08:42 PM Tom_L: define the block and the profile
08:44 PM Tom_L: define how 'thick' you want the passes and a finish pass if any
08:44 PM Tom_L: well on 2.5d there wouldn't be any
08:46 PM BGPNeighbored: that sounds like exactly what I want to do, but anytime I try I just get a little tool squiggling around a downward ramp in simulation
08:48 PM CaptHindsight: ramps is just an IO board with mostly passives and sockets for dinky stepper motors
08:48 PM Tom_L: maybe try defining a pocket cut and tell it you want layered cuts, whatever they happen to call them in that cad program
08:48 PM CaptHindsight: #marlin for questions about marlin
08:49 PM CaptHindsight: CAM is another story
08:49 PM Tom_L: sounds like a problem ahead of the hardware to me
08:49 PM CaptHindsight: marlin on a *duino with ramps io board
08:50 PM BGPNeighbored: directly between keyboard and chair, but hey, gotta piss with the pecker ya got
08:53 PM Tom_L: https://www.instructables.com/id/Fusion-360-CAM-Tutorial-for-CNC-Beginners/
08:54 PM Tom_L: may or may not help
08:55 PM CaptHindsight: https://camotics.org/ to see what 2d cam can get you
08:55 PM CaptHindsight: 3-axis CAM
08:56 PM CaptHindsight: another free tool that might be useful http://www.scorchworks.com/index.html
09:01 PM BGPNeighbored: as it turns out, all's I needed to do was click an arrow in f360
09:02 PM Tom_L: you're on your way then
09:28 PM XXCoder: whoa
09:28 PM XXCoder: grayout here
09:28 PM XXCoder: both montiors turned off and on, but computer managed to stay on
09:35 PM SpeedEvil is now known as Guest92779
10:20 PM flyback: BMCC
10:30 PM Elmo40: CaptHindsight, that CAMotics one is rather limiting.
10:30 PM Elmo40: https://camotics.org/gcode.html#missing-linuxcnc-codes
10:30 PM Elmo40: missing canned cycles?? that is important.
10:32 PM CaptHindsight: is for free
10:32 PM CaptHindsight: i did not say it was more better than MasterCAM
10:32 PM CaptHindsight: or better than sprinkles on ice cream
10:33 PM Tom_L: i'd take Mastercam over sprinkles though
10:34 PM Elmo40: ;-)
10:34 PM Elmo40: and the phrase is 'more gooder than...'
10:34 PM Elmo40: i'm waiting for MasterCAM-Slicer.
10:35 PM Tom_L: i think solidworks has one now
10:35 PM Elmo40: they have their shit together in the machining world, why not implement it into the additive world?
10:36 PM Elmo40: non-planar printing is coming around. still very early stages. don't know why it wasn't a thought 10 years ago!
10:38 PM Elmo40: they don't have a slicer
10:39 PM Elmo40: only STL support
10:39 PM Elmo40: but they created(?) a new 3D file format that is slowly being addopted.
10:44 PM Elmo40: ok, maybe not create but they prefer it over stl.
10:50 PM BGPNeighbored: aaand now I have a pretty toolpath in 360, and pronterface is all wtaf about the generated NC file
10:51 PM BGPNeighbored: do people get into this just to test the limits of frustration
10:58 PM Tom_L: neither package was designed for the other really
11:03 PM Tom_L: you could edit the post on f360 for pronterface if you wanted to make a custom post
11:06 PM Kevin`: using fusion 360 as a slicer for printing or pronterface for milling?
11:07 PM Kevin`: (not sure i'd especially trust either of those combinations)
11:08 PM Tom_L: he's basically got a 2.5d mill of sorts and wants to cut an airfoil using layers
11:08 PM Kevin`: as in, cut sheets and bond them?
11:10 PM Tom_L: not that i know of, i think it's one block
11:11 PM Kevin`: normal milling then? fusion 360 was pretty easy to get to post for me for milling with AXIS, might be able to dig that up if needed. although so should most people here I guess
11:12 PM Tom_L: i'm not entirely sure what all he has going on
11:13 PM Tom_L: ramps board controlled probably with marlin or some grbl derivative
