12:01 AM Techmorfic9428[m: The spindle is controlled with a on board module that has 0-10v for the speed.
12:11 AM Techmorfic9428[m: It goes to a VFD
12:11 AM CaptHindsight[m]: ah ok, I'm heading offline soon
12:11 AM Techmorfic9428[m: 👍
12:11 AM CaptHindsight[m]: if you already have all the drives for the motors looks like a https://mesaus.com/product/7i96s/ for you as well
12:11 AM CaptHindsight[m]: Step and Dir for the stepper motors
12:11 AM CaptHindsight[m]: and analog out for the VFD spindle
12:11 AM XXCoder: its actually in stock?
12:11 AM CaptHindsight[m]: 7 in stock at JT'
12:11 AM XXCoder: been a while. its been "will be in stock soon" or "not any time soon, sold out already" for while
12:11 AM CaptHindsight[m]: also 7 more at Mesa http://store.mesanet.com/index.php?route=product/product&product_id=374
12:14 AM Techmorfic9428[m: what is a good post processor for multi axis CNC for liniuxCNC?
12:22 AM isaacggw[m]: I am running it with a 7i96s
12:25 AM JoseIgnacioRomer: almost done wiring my 7i96s
12:26 AM JoseIgnacioRomer: i would really love it if it could be powered with 24v instead of 5
12:27 AM Bleepshop: JoseIgnacioRomer: 5V buck converter https://www.amazon.com/EPBOWPT-Converter-Regulator-Supply-Transformer/dp/B01M03288J
12:27 AM JoseIgnacioRomer: it would def be worth $20-30 more to me and probably others
12:28 AM JoseIgnacioRomer: yeah i am wiring that very exact one
12:28 AM JoseIgnacioRomer: i wish i didnt have to though
12:28 AM Bleepshop: Ive got one of these on order. https://www.amazon.com/dp/B0BF9WWX8B
12:31 AM JoseIgnacioRomer: there is room in the board, they could have put this there https://www.digikey.com/en/products/detail/mornsun-america-llc/VRB4805YMD-6WR3/16719439
12:31 AM JoseIgnacioRomer: bam, board is worth at least 30 bucks more now
12:48 AM Bleepshop: JoseIgnacioRomer: If you want to feed it >36V. That thing only works from 36V-75V.
12:49 AM JoseIgnacioRomer: yeah there is 2 versions of the same module
12:49 AM JoseIgnacioRomer: there is an identical one that can be fed with 24
12:50 AM * Bleepshop gets ready to call it a night.
12:53 AM Bleepshop: JoseIgnacioRomer: I was thinking about using one of these, but ordered the PSU instead. https://www.amazon.com/gp/product/B07KWVL77T
01:09 AM Deejay: moin
01:38 AM randy: morning
01:38 AM randy: happy new year.
01:38 AM Deejay: thanks, happy new year to you, too!
01:53 AM sensille: do you all use handwheels or just keyboard?
02:00 AM Deejay: keyboard
02:01 AM Loetmichel: keyboard
02:01 AM sensille: good, another $100 not spent :)
02:02 AM Loetmichel: (reminds me that i really should mount some e-stops on the two machines in the company, not good if we get checked by the BG and the only ones there are under the keyboard-drawer. nice and out of the way if you have an emergency)
02:02 AM Deejay: yay. $50 for me, $50 for Loetmichel ;)
02:03 AM sensille: Loetmichel: the tool length sensor is the estop :)
02:03 AM Loetmichel: (BG is basically the german version of OSHA)
02:04 AM Loetmichel: there is no tool lenght sensor (actually there is, somewhere in a drawer, never used it)
02:05 AM sensille: Loetmichel: btw, my 6040 with the new motors now runs at 12000mm/min, make s very nice jogging :)
02:06 AM Loetmichel: 200mm/sec? nice. I would expect the y-ballscrew to start to vibrate at that speed though
02:06 AM sensille: https://photos.app.goo.gl/Xf2pRZ4duAYNjEpa9
02:07 AM Loetmichel: IIRC my two 6040 started to resonate and lose steps because of it at about 100mm/sec
02:07 AM sensille: well, it does not sound totally clean, but i don't notice any vibrations
02:07 AM sensille: i guess the stepper driver takes care of that
02:08 AM Loetmichel: thats nothing the driver can manipulate
02:08 AM Loetmichel: Anybody knows what "kritische drehzahl bei wellen" is in english?
02:09 AM Loetmichel: its basically resonance in the shafts/ballscrews that are a product of shaft diameter, length of "free hanging" shaft and rotational speed
02:10 AM sensille: i noticed that with my old motors, too. already at much lower speeds. but with the new motors there's not a trace of it left
02:12 AM sensille: the motors run much smoother. that probably doesn't excite the vibration that much. and they quickly push through
02:13 AM Loetmichel: probably. But the effect i mean can even have "visible" standing waves in the ballscrews.
02:14 AM Loetmichel: at the right RPM you can see the 16mm ballscrew wobble in a sine or two between mounts
02:17 AM Loetmichel: and the ballnut acts like a guitar fret.
02:17 AM sensille: yeah, so the frequency changes quickly
02:17 AM Loetmichel: indeed
02:18 AM sensille: you have to hit just the right acceleration
02:20 AM Loetmichel: its a bit frightening to see a 16mm massive steel "guitar string" though
02:21 AM Loetmichel: reminds me of the time when they broke a 60 ton nominal anchor rope on the ship i served on.
02:22 AM sensille: *snap*
02:22 AM Loetmichel: You dive for cover REALLY quick when you hear a few 10 meters of arm thick carbon fibre reinforced nylon rope going not "BONNGG" but "TINNG TINGGG TIIIIGG BANG"
02:23 AM Loetmichel: (they forgot to losen one of the ropes that tied the ship to the pier and reversed out)
02:25 AM Loetmichel: the lose end of the thing hammered a 2 foot wide and 2 inch deep dent into the ship hull btw. and said hull was about 1/2 inch steel)
03:46 AM travis_farmer[m]: G'Morning
04:45 AM JT-Cave: morning
04:52 AM He[m]1: Mornin'
04:54 AM He[m]1: Was looking at hooking up the encoder passthrough on my JMC servos to linuxCNC yesterday, but the servo oscillates like heck now after enabling the encoder
04:54 AM Tom_L: morning
04:55 AM He[m]1: Read somewhere the P value should be 1000 and the FF1 should be 1 which they are, but I don't really know why the P should be 1000; I just want the encoder there so I don't lose the position of the axis when I disable the drive
04:56 AM He[m]1: Does anyone here have some experience with that?
05:04 AM Tom_L: back the P value off if it it oscillating
05:08 AM Tom_L: then add in a little I
05:18 AM He[m]1: Well I am running them in position mode, are you supposed to be tuning anything in linuxcnc then?
05:47 AM JT-Cave: https://gnipsel.com/linuxcnc-old/tuning/index.html
06:02 AM He[m]1: Am I misunderstanding something?
06:02 AM He[m]1: I'm running my drives in step/dir mode so I'm not sure I need any PID stuff
06:03 AM He[m]1: (outside of the drive)
06:17 AM pere: hi
06:17 AM He[m]1: Hello
06:17 AM JT-Cave: are you using a Mesa card?
06:17 AM He[m]1: Yeah I am
06:17 AM JT-Cave: they are more accurate if you have a PID for the stepgen
06:53 AM He[m]1: Nope, no luck
06:53 AM * He[m]1 uploaded an image: (142KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/zPkkBgaKIuHhDzKcktRKqBZa/image.png >
06:55 AM ZincBoy[CAON][m]: The 7i76 field IO inputs will not work for servo encoder inputs. You need a card with encoder inputs.
06:56 AM He[m]1: there's 1 encoder input on the 7I76 though
06:56 AM He[m]1: Just testing if I can get the servo encoder pass through to work at all before I get a daughter card with more encoder inputs
06:56 AM ZincBoy[CAON][m]: Ah, yes that will work. Usually used for the spindle but it will work for testing. What issue are you seeing?
06:58 AM ZincBoy[CAON][m]: You should see the encoder counter change in halshow when the servo moves.
07:02 AM travis_farmer[m]: so, i finally got some documentation about my ATC spindle. it has an output, like a tach signal, that outputs a high level, and two lows with each revolution. so it sounds like i can input this into my Mesa card, and get an accurate RPM count. i can also connect it to an arduinos interrupt input to test for rotation. this arduino can then output a high level signal when the spindle stops rotating, and input that into a Mesa pin
07:02 AM travis_farmer[m]: input. that way during an M6 remap, i can use an M66 (wait on input) to wait for the high signal. :-) this will make things very easy, i think.
07:03 AM He[m]1: The encoder counter does change when I move the motor
07:03 AM He[m]1: It starts oscillating when I use the default P=1000 and FF1=1 though
07:05 AM * He[m]1 uploaded an image: (41KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/wTdOaAxicSPeAZLGKRziCygr/image.png >
07:05 AM He[m]1: Quite badly
07:09 AM * He[m]1 uploaded an image: (41KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/LdaRpUpwUWvZBWyikFJJHbzI/image.png >
07:09 AM He[m]1: With P=0 there's a bit of delay from when the command is sent to where the encoder signal reaches linuxcnc, which I guess is causing the oscillations since it tried to compensate for that?
07:09 AM He[m]1: s/tried/tries/
07:13 AM * He[m]1 uploaded an image: (92KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/xuzbKUTzHhboxHpVfbievEjq/image.png >
07:13 AM He[m]1: That's with P=0, previous screenshot had some leftover error from the oscillations at P=1000
07:20 AM ZincBoy[CAON][m]: You need to tune the PID. You now have actual feedback and need to determine the correct P, I, D, and FF settings for your drive/motor/mechanical setup.
07:21 AM ZincBoy[CAON][m]: The P=1000 is only for stepgen systems where the feedback is just the input (kind of).
07:22 AM ZincBoy[CAON][m]: Note that this will be challenging as the drive is also closing the position loop and in general a PID on a PID controlled system is asking for issues.
07:25 AM He[m]1: Huh, that's not great
07:29 AM He[m]1: I was under the impression you could use the encoder feedback as a reference to where the machine is so you don't have to re-home every time you cut the enable line
07:31 AM He[m]1: Guess I should try and get an analog servo daughter card down the line so I don't have to stack 2 position loops then
07:33 AM ZincBoy[CAON][m]: You can do that. You just have to connect the encoder position value to the joint.<n>.motor-pos-fb only and not to the pid.<axis>.feedback as well. The pid.<axis>.feedback should be connected to the stepgen position output.
07:34 AM ZincBoy[CAON][m]: Note, I have not tried this so am not responsible for exciting behavior 🙂
07:41 AM He[m]1: I'll try that 🤔
07:59 AM He[m]1: Haha doesn't quite work, now if you introduce an error with the enable line low it jerks the motor when you re-enable linuxcnc
08:02 AM ZincBoy[CAON][m]: That will be true even if you has the position loop closed in linuxcnc. This is meant more for when you hit estop and the position will be know. I use this on my machine and there is no jerk coming out of estop.
08:03 AM ZincBoy[CAON][m]: Also, that jerk might be the drive itself.
08:11 AM He[m]1: The jerk is not the drive, still manually switching the ENA line with an actual switch on that one
08:11 AM He[m]1: It happens every time I toggle the "power" softkey in lcnc
08:12 AM ZincBoy[CAON][m]: What happens when you toggle estop?
08:14 AM He[m]1: It goes into estop, and depending on if I move the motor by hand during that time it'll also lunge a bit on reapplying the power softkey after disabling estop
08:15 AM He[m]1: it does count how far you've moved the motor though, and the oscillations are gone even with P=1000
08:16 AM ZincBoy[CAON][m]: Hmm. I don't see that on my machine but I can't move the axis by hand. The Z droops a bit though before the break engages so I would expect to see it there. I have the position loop closed in linuxcnc with analog drives though.
08:17 AM ZincBoy[CAON][m]: Is it a problem that it jerks on start? It shouldn't be too much as you shouldn't be moving the machine by hand normally.
08:17 AM He[m]1: "The Z droops a bit though before the break engages"
08:17 AM He[m]1: Yeah that's exactly why I want to go through all the trouble of hooking up the encoders 🙂
08:19 AM He[m]1: Not really, I'll just have to confirm it returns to the position it thinks it's returning to, since it doesn't seem to resolve the error at all arm
08:19 AM He[m]1: s/arm/atm/
08:20 AM He[m]1: Guess I can use the step counter on the drive for that actually
08:22 AM ZincBoy[CAON][m]: Yes, it is really nice to be able to estop and not worry about losing your position. Makes me not worry about hitting the big red button 🙂
08:41 AM Tom_L: JT-Cave, where did you hide the rpi kernel build directions?
08:42 AM He[m]1: Yep it doesn't seem to return to the right position anymore after a disturbance
08:42 AM Tom_L: maybe i found it..
08:43 AM ZincBoy[CAON][m]: But if you command back to the original position does it go there?
08:43 AM ZincBoy[CAON][m]: My machine does not move back to where it was, it just knows where it is.
08:44 AM He[m]1: Nope it'll remain offset
08:45 AM ZincBoy[CAON][m]: That is less useful then.
08:53 AM Tom_L: JT-Cave, that patch has moved to /older/ now
08:57 AM He[m]1: Yeah, kind of the opposite of useful tbh
08:57 AM He[m]1: https://streamable.com/t7j7ji
08:58 AM He[m]1: Here's a video of what it's doing, sorry about the mumbling
08:59 AM Tom_L: were you able to reduce the oscillations?
08:59 AM Tom_L: did you try any P numbers beside 0 & 1000?
09:02 AM He[m]1: I did try some other numbers when everything was still in closed loop mode, to varying degrees of success
09:02 AM Tom_L: in a normal system you want to get P to oscillate then back off a little and add in a little I
09:02 AM Tom_L: not sure if that will help here
09:16 AM JT-Shop: Tom_L, https://gnipsel.com/linuxcnc/index.html
09:20 AM Tom_L: yeah i'm building it atm
09:20 AM Tom_L: the patch moved though
09:24 AM He[m]1: Yeah don't think adding in more I would help, so guess I'm either going full step/dir or getting an analog card
09:25 AM He[m]1: Or I could try tuning the servo in step/dir mode with the halscope but that seems incredibly hacky
09:45 AM ZincBoy[CAON][m]: Tuning the PID in step/dir mode using halscope would be a normal way to do it. The problem is that you have a PID loop in the drive already and you are putting another one on top. You might be able to tune it but performance might not be great.
09:46 AM He[m]1: What does normal even mean in this case?
09:46 AM He[m]1: For a stepper with an encoder?
09:46 AM Tom_L: different situation here but i added one to my bldc spindle motor and it greatly improved the low rpm range
09:52 AM He[m]1: Yeah, that sounds about right to me lol
09:54 AM He[m]1: well, guess I should open up a forum thread about this
09:54 AM He[m]1: I guess it's not **really** critical for now to have the encoder loop back into linuxcnc
10:34 AM JT-Cave: Tom_L, ok
10:43 AM Tom_L: does rpi use grub?
11:00 AM travis_farmer[m]: Tom_L: it looks like the answer is "no". it seems to use it's own bootloader in the boot file system. rpi4 moved this bootloader to an EEPROM... according to google...
11:07 AM isaacggw[m]: Is there a way to wire up the off the shelf electronics of my pm25 spindle to my 7i96s and control it with lcnc?
11:09 AM roguish[m]: isaacggw: strongly suggest an isolator between your mesa cards and other electronics. Mesa's are fairly electrically fragile (I have damaged several.)
11:11 AM Plaid: isaacggw[m]: Generally yes. That's the point of the 7i96s. What it takes, IDK. What signals does the spindle have and need?
11:12 AM Plaid: And roughly what kind of machine do you have (lathe, mill, router)
11:13 AM isaacggw[m]: It is a PM25 mill that I am converting over to cnc
11:14 AM * isaacggw[m] uploaded an image: (116KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/aXmDTCJLKeaFtWKBdGAVtarq/IMG_1020.jpg >
11:15 AM Bleepshop: roguish[m]: Got a collection of dead cards?
11:15 AM isaacggw[m]: This is the wiring on the side of the mill
11:15 AM isaacggw[m]: ?
11:15 AM isaacggw[m]: I have one 7i96s
11:16 AM isaacggw[m]: that is driving the hole mill
11:16 AM isaacggw[m]: it is controlled by a pi4
11:16 AM JT-Shop: Tom_L, I don't think so
11:17 AM Plaid: isaacggw[m]: I'm not that skilled, but yes. It's designed to do exactly what you want.
11:17 AM Bleepshop: isaacggw[m]: Looks fairly straight forward. For the sake of paranoia I'd couple the shaft on that potentiometer to a stepper and control that from the 7i96s.
11:18 AM Plaid: I thought the 7i96s could fake a pot
11:18 AM isaacggw[m]: I do not understand what you mean
11:19 AM ZincBoy[CAON][m]: You can connect the pot to the spindle out on the 7i96s. It is isolated on the 7i76
11:19 AM Bleepshop: Plaid: They can, but a bit of insulation in the middle and you don';t have to worry about cooking the 7i96s.
11:19 AM Plaid: My LCNC skills aren't that hot, but I think the analog control can be wired to fake being the pot. Open it up, and see if you can find the model of VFD/spindle controller in it.
11:20 AM ZincBoy[CAON][m]: You just need to make sure the voltage on the pot is not greater than 10V. As long as it is less than that, no other isolation is needed.
11:20 AM ZincBoy[CAON][m]: This is complete overkill.
11:20 AM Plaid: I'm on my first machine still, and I haven't cut any chips, so I'm not an expert, but there's some super experts here. I just know the basics, and i know what the smarter people will need to know.
11:21 AM Bleepshop: JT-Cave: Can I get to the same point of 13/lcnc if I start with the buster/lcnc iso and upgrade via apt?
11:21 AM Bleepshop: ZincBoy[CAON][m]: That's my middle name. LOL
11:22 AM isaacggw[m]: Ok
11:22 AM ZincBoy[CAON][m]: Besides the pot, you will need a couple of control signals. Likely run and direction. It is not clear on the schematic but I am pretty sure they will be on the "change over switch" connections.
11:22 AM isaacggw[m]: For changing diction of the spindle, use 2 relays?
11:23 AM isaacggw[m]: And is there an encoder you would recommend?
11:24 AM ZincBoy[CAON][m]: Should not need relays. I bet the "change over switch" is 24V or something like that. You should be able to drive those IO directly from the 7i76s but you need to confirm the voltages and if they are isolated before doing so.
11:24 AM Plaid: isaacggw[m]: Your machine probably has a VFD unit inside. You may be able to find a manual for that VFD and be able to reconfigure it, and/or it may already have speed information available.
11:24 AM ZincBoy[CAON][m]: It has one of those cheapo BLDC drives. With luck the silkscreen on the board will have pin names.
11:25 AM Plaid: <-- Dumb person ^ Smart person
11:25 AM roguish[m]: Bleepshop: a shoe box fulll..............
11:26 AM ZincBoy[CAON][m]: Are you looking to close the spindle loop with with the encoder? I have used these with good results: https://www.ebay.ca/itm/333709462343?epid=2159915706&hash=item4db2a24b47:g:Z8wAAOSwFFBdpCg-
11:26 AM ZincBoy[CAON][m]: You will need a timing belt and pulleys to connect it to the spindle. The pulley ratio should be 1:1.
11:26 AM Tom_L: i use omron on my spindle but it's alot smaller encoder
11:27 AM Tom_L: good quality imo
11:27 AM isaacggw[m]: Ok, thanks
11:27 AM Plaid: Just a note here... you have two choices. You can setup a voltage -> RPM mapping. That'll work. You can also go more fancy, and do "closed loop" where you actually monitor the spindle speed and adjust the voltage to match. More work, but better results
11:28 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Spindle/Encoder1.jpg
11:28 AM ZincBoy[CAON][m]: On my NM145 which is similar to your mill, I coupled the encoder to the motor shaft. If the spindle is driven with a timing belt there is negligible error and it simplifies the physical connection.
11:29 AM isaacggw[m]: Cool
11:31 AM isaacggw[m]: One last question, I want to add a tool height setter to my mill. What would you recommend I use? Also, can I do that strate in the defalut lcnc gui, or do i need to use prob basic?
11:31 AM Tom_L: i just use a 1" gage block
11:32 AM Tom_L: some use a roll pin
11:32 AM Bleepshop: roguish[m]: What all have you cooked?
11:32 AM * Bleepshop has a surface mount rework station available.
11:32 AM Plaid: And with the FPGA shortage...
11:33 AM Bleepshop: Plaid: That's where the RV901Ts are nice. FPGA donor. LOL
11:33 AM ZincBoy[CAON][m]: I used one of these before I got a probe and tool setter: https://www.edgetechnologyproducts.com/pro-touch-off-gage-04-000/
11:34 AM Tom_L: yeah those types tend to be a bit too tall for my mill
11:34 AM Tom_L: i have one
11:35 AM roguish[m]: https://drewtronics.org/
11:36 AM He[m]1: Well managed to put most of my questions into the forum post, I'll stop the linux-ing for today, confused myself enough 😂
11:37 AM Bleepshop: I've just got a probe input wired and a roll of 0.010" sticky foil tape. Stick the tape on the stock, clip the probe lead to the tape and run a probe cycle.
11:39 AM Tom_L: and you're only off by maybe .002 - .003"
11:40 AM Tom_L: (tape thickness)
11:40 AM Bleepshop: Tom_L: Close enough for anything I'm doing right now. If I need more precision I'll come up with a better method later.
11:41 AM Bleepshop: Tom_L: Tape is 0.010. More like 0.001 [glue thickness].
11:45 AM Bleepshop: Anybody? Can I start with the lcnc/Buster[10] iso and upgrade to bookworm[12] or sid[13] via apt?
11:45 AM * Bleepshop is having hell getting glade 3.8.6 compiled on 13.
11:48 AM JT-Shop: do you need 13 for some reason?
11:49 AM * JT-Shop goes to take a nap
11:50 AM roguish[m]: Bleepshop: I don't advise going past D11, the current release. Unless you want to get caught up in the upgrade game.
11:50 AM roguish[m]: JT-Shop: already????
11:50 AM Bleepshop: JT-Cave: It's proved to be fast and stable?
11:50 AM roguish[m]: you ARE retired.
11:51 AM Bleepshop: So that's what I've been doing wrong all these years. Skipping naps. LOL
11:54 AM travis_farmer[m]: i can honestly say, my test run of retirement is nice, but pays very little... if only i got a SS check like some lucky folks ;-)
11:58 AM JT-Cave: roguish[m], it's noon here
11:59 AM Tom_L: JT-Cave, testing the deb atm
12:02 PM Tom_L: ends up in the Accessories menu
12:02 PM Tom_L: starts up ok
12:02 PM Bleepshop: roguish[m]: Now I'm wanting to rummage through your shoebox. Might be all kinds of goodies. LOL
12:02 PM Bleepshop: Tom_L: What is it?
12:03 PM Tom_L: jt's lcnc deb
12:03 PM Tom_L: for rpi4 armhf
12:03 PM Tom_L: (32 bit)
12:03 PM Bleepshop: Neat.
12:04 PM Bleepshop: Not so neat. 64bits or bust! LOL
12:04 PM Tom_L: he's working on that currently
12:04 PM Tom_L: after nap time of course
12:07 PM unterhaus: I'm going to try to move my desk without taking anything off of it. Wish me luck.
12:08 PM * Bleepshop wonders if unterhaus meant to reset his connection of if that qualifies as an 'Oops!'.

12:18 PM CaptHindsight[m]: ZincBoy[CA, ON]: are those OMRON E6B2-CWZ6C Rotary Encoder clones or actual Omrons?
12:21 PM CaptHindsight[m]: https://www.ebay.com/itm/333732835593 2k ppr for $23 usd

12:22 PM ZincBoy[CAON][m]: That was just the first link I found. At best those are grey market imports. The label doesn't look quite like the ones I have:
12:26 PM CaptHindsight[m]: magnetic or glass wheels? ZincBoy[CA, ON]
12:27 PM ZincBoy[CAON][m]: Optical wheels. Not magnetic.
12:27 PM CaptHindsight[m]: wheel/disc
12:27 PM CaptHindsight[m]: about time somebody figured out how to make them
12:29 PM CaptHindsight[m]: https://www.alibaba.com/showroom/glass-encoder-disk.html
12:31 PM CaptHindsight[m]: $0.20 / piece
12:33 PM ZincBoy[CAON][m]: The encoder wheels are easy. You have been able to buy them pretty cheap for a long time. The real challenge is the optical receiver. They are a bit more expensive and harder to get.
12:39 PM CaptHindsight[m]: now to find them with decent bearings installed
12:42 PM travis_farmer[m]: hmmm, updating my HAL file to prep for my ATC spindle... seems complex at 413 lines, but i "think" it will work... still have to work on my M6 remap, but that can be done easier when the spindle in mounted and working. having a blast, configuring and researching! :-)
12:42 PM CaptHindsight[m]: ZincBoy[CA, ON]: I thought that you worked in the optical fiber industry
12:43 PM ZincBoy[CAON][m]: I do (ICs that go in optical modules for datacenters).
12:52 PM unterhaus: we aren't supposed to have stinkbugs here in pennsylvania
12:52 PM JT-Shop: <Tom_L> the patch moved though
12:52 PM JT-Shop: which patch
01:04 PM XXCoder: stinkbugs is everywhere nowdays
01:04 PM XXCoder: even behind you
01:06 PM travis_farmer[m]: ..starting to think i peed in someone's cornflakes, or something...
01:07 PM Bleepshop: travis_farmer[m4: I'm firmly convinced that in past lives I pissed off entire pantheons of gods and have porbably annoyed the current crop.
01:13 PM roguish[m]: CaptHindsight: most of those encoders and parts are knockoffs of HP heds units, or BEI units.
01:15 PM unterhaus: I'm not sure what I did to make Bill Gates mad, but I'm pretty sure he instructed the windows devs to do something to punish me every day
01:15 PM XXCoder: bill gates have no power over me, I dont use windows
01:15 PM unterhaus: I saw that a majority of devs moved from mac to linux
01:16 PM unterhaus: but I have stuff I need to develop for windows, so that's why I use it
01:19 PM roycroft: well i dusted off my trigonometry knowledge, and i have a design now for a circle sander that should be able to directly dial in the size in increments of 0.001" :)
01:20 PM roycroft: now i get to figure out how to build a router table jig to do the same thing, because i think that would be useful
01:23 PM CaptHindsight[m]: is everyone back to work tomorrow or today?
01:23 PM XXCoder: dunno
01:23 PM * travis_farmer[m] doesn't have any work until the machine is finished...
01:23 PM JT-Woodshop: how long should I keep the band clamp on the segments with titebond III?
01:24 PM * JT-Woodshop thought about work... does that count?
01:24 PM roycroft: usually a half hour is fine, jt-woodshop
01:25 PM roycroft: if the shop is cool, a couple hours
01:25 PM roycroft: and i'm back at work tomorrow
01:25 PM travis_farmer[m]: depending on humidity...
01:26 PM ZincBoy[CAON][m]: The 9th for me. Burning off vacation from last year before it expires 🙂
01:26 PM JT-Woodshop: 71°F 45%
01:26 PM roycroft: although i'm working on my side hustle today
01:27 PM roycroft: and dealing with members
01:28 PM roycroft: fripping no-lifes who post nasty emails all weekend long instead of enjoying the holiday :)
01:30 PM * JT[m]1 uploaded an image: (338KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/TmgYBbKzyxAhFHGYJkMFzlNb/20230102_132907.jpg >
01:30 PM * travis_farmer[m] wonders if he is a fripping no-life...
01:30 PM XXCoder: the big final version?
01:31 PM JT-Woodshop: purple heart segments passes the rubber band test
01:31 PM JT-Woodshop: yup, making two
01:32 PM XXCoder: nice
01:32 PM XXCoder: one for me right? ;)
01:32 PM unterhaus: I have luthier's tape for jobs like that
01:32 PM roycroft: i'm making a box with rounded ends
01:32 PM roycroft: i'm still deciding how to make the ends, but i'm leaning towards cutting thin strips of hardwood and gluing them up around a form
01:32 PM unterhaus: it's called that because if you are working on guitars, you will pay 5x as much for tape
01:33 PM roycroft: the radius is about 3.5", and they will be 1/2" thick
01:33 PM roycroft: i don't think steam bending is going to work very well with that tight of a radius
01:33 PM unterhaus: I was looking for some 8/4 maple and it looks like they want outlandish amounts of money for it at the closest wood supply
01:34 PM unterhaus: they don't have regular old maple on their price list, only "flamed tiger maple"
01:34 PM roycroft: stewart macdonald is a great place to go when you want cheap tools/supplies that have been rebranded and marked up several times over cost
01:34 PM unterhaus: it's really good tape, I'll give them that
01:35 PM unterhaus: never figured out where to get it otherwise
01:35 PM CaptHindsight[m]: guitar tape
01:35 PM unterhaus: I wonder if the Amish sawmills will sell to someone like me
01:36 PM unterhaus: wooden mind some white oak, which is all they have from what I can tell
01:36 PM travis_farmer[m]: clearly i pissed somebody off... tried to start conversation several times today, and been ignored... just wish i knew what i did...
01:36 PM roycroft: it would be nice if lived back east, or were there for some other reason
01:37 PM roycroft: i'm looking to get a trailer for my urban logging work, and i need some decking for it
01:37 PM roycroft: 8/4 rough white oak would be perfect
01:37 PM unterhaus: I thought I was in a good place to buy wood, but it doesn't look good
01:37 PM roycroft: and i think those amish sawyers would be the best folks to get it from
01:37 PM unterhaus: I don't know if they will sell that white oak to me though
01:38 PM unterhaus: they are all in the next valley over, aka "the land that time forgot"
01:38 PM roycroft: i go to the local sawyers, and they are either not interested in anything but "river table" slabs these days, or they think that gnarly, rough timber has the same value as clear, figured timber
01:39 PM roycroft: so 8/4 white oak that's all knotty and twisty is still going to be $8/bf
01:39 PM unterhaus: that's what the dealer up the way is doing now
01:39 PM roycroft: "it's hardwood!"
01:39 PM unterhaus: if you really want to be shocked, their prices for crotch wood did it for me
01:39 PM roycroft: yeah, but it's still pretty crappy
01:40 PM roycroft: and for trailer decking, i want green wood
01:40 PM roycroft: kiln-dried would be stupid, because it will be 20% in no time after i install it on the trailer
01:41 PM roycroft: it sucks right now
01:41 PM roycroft: wood that i used to be able to get at scrap prices, because it really is scrap, is now going for premium prices
01:41 PM roycroft: i make small stuff, and can work around flaws easily
01:42 PM roycroft: but flaws are now features
01:42 PM unterhaus: https://irionlumber.com/
01:42 PM unterhaus: city fold ruined them, I think
01:42 PM unterhaus: city folk
01:42 PM roycroft: they are opportunities to pour epoxy (barf) or, even worse, do a shitload of that horrible patchwork inlay crap (double barf)
01:43 PM roycroft: how far are you from cogan station?
01:43 PM DigitalReaper: IMO epoxy pours can be beautiful if done right. it's rarely done right.
01:44 PM unterhaus: I have some amazing walnut crotches that are worth hundreds of $ according to them
01:44 PM roycroft: it's near williamsport
01:44 PM unterhaus: cogan station is an hour and a half drive from here, I think
01:44 PM roycroft: oh, so a trip
01:45 PM roycroft: i was going to suggest you check out lumber capital log yard
01:45 PM unterhaus: so is wellsboro, but all the closer dealers went under
01:46 PM roycroft: matt estlea made the only river table i have ever liked
01:46 PM roycroft: because his design is pure snark
01:47 PM unterhaus: I think some of them are okay, not my style though
01:47 PM roycroft: he has an actual river running through his table
01:47 PM roycroft: well, an actual fake river
01:47 PM roycroft: actual liquid runs through the river bed in his table
01:49 PM unterhaus: there is a desk that Krenov made that I want to copy
01:49 PM unterhaus: I have the walnut for it, it's curved almost exactly the way his was
01:49 PM XXCoder: roy I wonder how long it would run before wood gets rotted
01:50 PM roycroft: https://www.youtube.com/watch?v=FsistC0dqjc
01:50 PM roycroft: matt's river table build
01:50 PM roycroft: i've posted that link before
01:50 PM roycroft: xxcoder: i doubt it will rot - he built it very well
01:50 PM roycroft: the wood should never get wet
01:51 PM XXCoder: nice lol though if I had it, I bet I would unplug it and remove water before long
01:51 PM unterhaus: I have some nice walnut my BiL cut that would make a good river table
01:51 PM unterhaus: split right down the middle of the tree
01:52 PM unterhaus: but I'm planning on gluing it back together
01:52 PM XXCoder: "good" river table lol
01:53 PM roycroft: epoxy is doing to fine woodworking what laser printers did to typography
01:54 PM roycroft: hint: laser printers destroyed typography
01:54 PM CaptHindsight[m]: easiest way to the money
01:55 PM XXCoder: in least river tables arent that insane high voltage electric thing thats spreading on youtube and maiming or killing people
01:55 PM XXCoder: how to cook that yt channel tried to warn people, and video was yoinked and they was warned
01:55 PM XXCoder: they reversed the decision but yeah, high volt crap stuff is untouched
01:56 PM JT-Shop: inventory done... that's enough work for today :)
01:56 PM DigitalReaper: HV thing? lichtenburg?
01:56 PM Tom_L: JT-Shop, the kernel patch in your tutorial
01:56 PM Tom_L: moved
01:57 PM roycroft: i fortunately don't have to do inventory this year
01:57 PM roycroft: next year, though, i'll need to do that
01:57 PM CaptHindsight[m]: smartphones drive graphic design and typography
01:58 PM JT-Shop: seems to still be at https://mirrors.edge.kernel.org/pub/linux/kernel/projects/rt/5.15/older/patch-5.15.76-rt53.patch.gz
01:58 PM Tom_L: yes the link didn't reflect that though
01:59 PM Tom_L: https://www.gnipsel.com/linuxcnc/kernel.html
01:59 PM JT-Shop: oh that one
01:59 PM Tom_L: did you make another one?
01:59 PM JT-Shop: https://gnipsel.com/linuxcnc/rpi4-11.html I thought you meant this one
02:00 PM Tom_L: heh i was following the other one for the rpi
02:00 PM Tom_L: cause i didn't know that was there
02:00 PM JT-Shop: the one you linked was done for debian pc
02:00 PM Tom_L: didn't do so well on the pi either
02:00 PM Tom_L: right up to the install part :)
02:00 PM Tom_L: i'll run thru it again
02:00 PM JT-Shop: ok
02:00 PM Tom_L: lcnc did install ok
02:01 PM JT-Shop: good
02:01 PM Tom_L: but it's in the Accessories folder
02:01 PM Tom_L: menu
02:02 PM XXCoder: https://youtu.be/wzosDKcXQ0I?list=PLPT0YU_0VLHxJMqHBC2_OMTYWwQ5z_iP4 the video that youtube blocked for short time
02:03 PM XXCoder: she talks about it at 10 minutes in
02:09 PM travis_farmer[m]: checked the logs, still no idea why i am being ignored, or am i even showing up? i have just posted updates on stuff i learned regarding my spindle... very odd :-(
02:10 PM ZincBoy[CAON][m]: You can make that safer as long as you use the same PPE as people working on live HV lines. Minimum of _tested_ HV gauntlets and everything isolated from ground. Still not a good idea and I wouldn't do it even with the PPE. I preferred it when the way to make those was to send some acrylic blocks though a gamma irradiator and then to smack a nail into one end.
02:10 PM DigitalReaper: tldw: using a microwave over transformer (2KV+) to make https://en.wikipedia.org/wiki/Lichtenberg_figure
02:10 PM DigitalReaper: *oven
02:11 PM ZincBoy[CAON][m]: Yes, that block is what I was thinking of.
02:14 PM ZincBoy[CAON][m]: Are you talking about here? I see your comments.
02:19 PM * JT-Woodshop breaks down a 8' x 8" x 5/4 slab of white oak
02:23 PM * travis_farmer[m] retires to his music, and settles on doing more research...
02:41 PM * Bleepshop downloaded the Busrter iso, chopped some firewood, wrote it to a Ventoy key, chopped some more firewood, fired up the live and realized something is missing...
02:42 PM Bleepshop: Where's the Install to Harddrive icon? LOL
02:42 PM CaptHindsight[m]: XXCoder: the writing in the comments is so unclear, did youtube block the HV wood burning video or the video about unsafe the HV wood burning or both?
02:43 PM CaptHindsight[m]: * video about how unsafe the, * wood burning is or both?
02:43 PM XXCoder: the warning video I linked was one that was blocked for a bit
02:43 PM CaptHindsight[m]: fixed my unclear writing
02:43 PM XXCoder: none of "how tos" was blocked
02:43 PM CaptHindsight[m]: they blocked the safety video?
02:43 PM XXCoder: yup
02:44 PM XXCoder: crazy isnt it
02:44 PM CaptHindsight[m]: was the HV wood burning video ever blocked?
02:44 PM XXCoder: videos as there is many, and none was
02:45 PM CaptHindsight[m]: ok
02:46 PM CaptHindsight[m]: tonight on Dying to be Famous, HV wood burning
02:47 PM CaptHindsight[m]: next week, quickest self inflicted head shot
02:47 PM CaptHindsight[m]: right after "Ow my balls"
02:48 PM XXCoder: lol
02:49 PM XXCoder: i found it funny that actor for "ow my balls" does not wear protection even though hes in show where his balls gets hit by people and stuff
02:49 PM XXCoder: so he kneels over after being hit by some fan
02:50 PM CaptHindsight[m]: when they wrote that film they thought it might get as bad as people wearing the plastic shoes, little did they know
02:56 PM travis_farmer[m]: Question, looking at air filters for my ATC spindle, for the pneumatic air. says it needs dry air filtered by first a 5 micron and then a 0.1 micron filter... this really needed? honestly asking, as the 0.1 micron filters are harder to find, inexpensively.
03:01 PM ZincBoy[CAON][m]: something like this would work fine: https://www.compressorworld.com/8-cfm-fine-coalescing-filter-nano-filter-compressor-1-4-npt-nf0008m01.html
03:02 PM ZincBoy[CAON][m]: Since that spindle uses purge air to keep dust out of the bearings, the 0.1 micron would be needed to keep the bearings alive. I would not run without the recommended filters.
03:02 PM travis_farmer[m]: ok, thank you
03:03 PM ZincBoy[CAON][m]: You only need the fine filtration for the purge input. The tool release cylinder will be fine with the 5um filtered air.
03:03 PM JT-Woodshop: nice the white oak boards cleaned up at 1" thick
03:04 PM travis_farmer[m]: ok, good to know, Zinc :-)
03:06 PM JT-Woodshop: travis_farmer[m], what do you make?
03:07 PM travis_farmer[m]: JT-Woodshop: planning on making signs and furniture with designs carved into them
03:07 PM JT-Woodshop: cool
03:08 PM JT-Woodshop: I assume you know about F-Engrave
03:08 PM travis_farmer[m]: i was employed as a rough/finish/cabinet carpenter for a bit, got the machine, and have dreamed of using it for work for a while
03:09 PM travis_farmer[m]: i do not
03:09 PM JT-Woodshop: you need that!!!!
03:09 PM JT-Woodshop: https://www.scorchworks.com/Fengrave/fengrave.html
03:12 PM travis_farmer[m]: hmmmm, looks very interesting (downloaded), and cheaper than Vetric Vcarve Pro :-)
03:13 PM JT-Woodshop: works great, been using it for years
03:25 PM XXCoder: that was what i was thinking on using when I was doing tests on router
03:25 PM XXCoder: man I want room to run it lol
03:48 PM JT-Woodshop: if I was strapped for cash and needed to get a router table going I'd have went with this for a few years https://www.amazon.com/PortaMate-PM-P254-Portamate-Router-Motor/dp/B00TBF5DSY
03:48 PM * JT-Woodshop likes his on the router table
03:48 PM ZincBoy[CAON][m]: Thanks for mentioning that. I just tried it out and it is not quite as good as vcarve for lineart carving. Still pretty good for the price 🙂
03:49 PM JT-Woodshop: it does work well for v carving
03:51 PM ZincBoy[CAON][m]: It barfed on the project I am working on right now. Vcarve generated the toolpath without issues while the one generated by F-engrave was not usable. This is using the same dxf file as a base. I am sure I could get it to work if I beat my head against the wall enough 🙂
03:53 PM JT-Woodshop: the only thing I've used it for is signs
03:56 PM ZincBoy[CAON][m]: It worked fine for text but the file I am using has lots of nested shapes and fine geometry. That is what seemed to trip it up.
03:56 PM travis_farmer[m]: my original spindle, was a Makita RF1101. though the machine came with a 5HP 3PH Perske. then i learned about VFDs, and got the perske running. worked great for a while, then the VFD started crapping out on communication, and the perske started howling like it was a full moon. i could have bought a replacement VFD and got the Perske overhauled, but i chose to upgrade to the ATC spindle instead.
03:59 PM travis_farmer[m]: this is what the Perske is: https://www.cncpd.com/product/perske-vs-60-11-2-5hp-spindle-motor/
04:13 PM * JT-Woodshop hunts for the last pieces of wood for the feature ring
04:13 PM Bleepshop: JT-Cave: Know anybody that wants a pair od Porter Cable 7815s cheap?
04:13 PM JT-Woodshop: is that the old one's?
04:13 PM Bleepshop: The heavy amuminum ones with variable speed? Yeah
04:14 PM Bleepshop: aluminum.
04:16 PM Bleepshop: JT-Woodshop: Got 2 of the motors, no base and a clamp mount for a CNC or router table.. https://www.woodmagazine.com/review/routers/fixed-base-routers/porter-cable-3-14-hp-fixed-base-router-7518
04:22 PM JT-Woodshop: don't know anyone that needs one... now
04:22 PM JT-Woodshop: I read the newer ones are crap
04:32 PM roycroft: 7518s are going for a premium now
04:32 PM roycroft: they are very desirable
04:32 PM roycroft: i still have mine from the early 1980s, back when they still made them well
04:33 PM roycroft: it was my router table router for years and years, but now that i'm using an 80mm spindle for that, it's back up top and is my heavy-duty hand-held router
04:34 PM roycroft: that machine is constantly saving me $1500
04:34 PM roycroft: because every time i think about getting a festool of2200 + the auxiliary base kit, i think about my 7518 and remember what a great machine that is
04:34 PM roycroft: and i don't spend the $1500
04:37 PM * JT-Woodshop hunts for the best piece of white oak for the next pieces
04:39 PM XXCoder: roy nice lol
04:42 PM isaacggw[m]: ZincBoy[CA, ON] do you have any photos of how you have your encoder mounted to your mill?
04:46 PM JT-Woodshop: thunder says time to head inside
04:46 PM XXCoder: wow nice of it to let you know first
04:47 PM travis_farmer[m]: thunder?
04:47 PM * ZincBoy[CAON][m] uploaded an image: (239KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/KcACjseqJkBnIziGKbOkPOQG/image.png >
04:47 PM ZincBoy[CAON][m]: I took a look earlier and I can't find any. I sold that machine so don't have it for reference any more. All I have is the bracket design. It was bolted to the head casting above the spindle motor and a flexible coupling was used to connect the encoder to the motor.
04:49 PM travis_farmer[m]: hmmm, checked the online weather radar, and yup, looks like thunder over yonder...
04:52 PM travis_farmer[m]: Mmmm, tuna-noodle casserole for supper tonight :-)
04:53 PM roycroft: i haven't decided on what will be for dinner tonight yet
04:53 PM roycroft: i was just starting to think about that
04:54 PM travis_farmer[m]: ramen noodles? ;-)
04:55 PM roycroft: probably not
04:55 PM roycroft: i mean, there's a great ramen place in town
04:55 PM roycroft: the owner is from japan, and did a 7 year apprenticeship learning how to make ramen
04:55 PM roycroft: when i want ramen i go there
04:56 PM XXCoder: nice
04:56 PM XXCoder: if I ever go south near you again, ill ask you for that location lol
04:57 PM roycroft: toshi's ramen
04:57 PM roycroft: https://toshisramen.com
04:57 PM roycroft: his website says he apprentices for 2 years
04:58 PM roycroft: but he told me 7 years - that may have been his total training, with 2 years of formal apprenticeship
04:58 PM XXCoder: if I ever menion going south, remind me if you remember :D
04:58 PM roycroft: that doesn't really matter though
04:58 PM roycroft: it's delicious
04:58 PM XXCoder: it could be general food training, then 2 years ramen
04:58 PM roycroft: yeah
04:58 PM roycroft: whatever it is
04:58 PM roycroft: he makes the good stuff :)
04:59 PM XXCoder: nice
04:59 PM XXCoder: i recommand you rice junkie, but location is bit hard to get to now. they closed the location I used to go to
04:59 PM roycroft: there's another ramen place in fifth street public market, but it's not as good

05:20 PM XXCoder: it'd be impossible for me bah lol
05:24 PM roycroft: when i used to have satellite tv it would go out during a hard rainstorm fairly often
05:25 PM roycroft: this is not a good part of the world for satellite tv for that reason
05:25 PM roycroft: and especially not a good part of the world for satellite internet or phone service
05:30 PM JT-Cave: XXCoder, I think you would felt the thunder it was really close and vibrated the shop
05:31 PM JT-Cave: ain't doing squat now lol
05:31 PM Tom_L: jt your sat seems to do better with the new service
05:31 PM JT-Cave: way better

05:49 PM Tom_L: JT-Cave, did you bump the version on the header
05:50 PM pere: Bleepshop: :)
05:55 PM Tom_L: JT-Cave, #75
06:04 PM Tom_L: JT-Cave, on daughter cards you should add the 7i47s to the manual list
06:20 PM Bleepshop: Crap! Now I've got the '7i96s hm2/hm2_7i96s.0: error finishing read! iter = 7' error.
06:21 PM roguish[m]: Bleepshop: that's a NIC problem
06:21 PM roguish[m]: which rt kernel are you running?
06:22 PM roguish[m]: fall back to a 4.xxx kernel.
06:22 PM Bleepshop: roguish[m]: Certainly is. And the bigger problem is hte lack of spares to swap it out with. I've got PCI out the wazoo and only one PCIe.
06:23 PM Bleepshop: Linux accu-cut 4.19.0-21-rt-amd64 #1 SMP PREEMPT RT Debian 4.19.249-2 (2022-06-30) x86_64
06:24 PM roguish[m]: PCW (mr. mesa) likes Intel based NIC cards,
06:34 PM Bleepshop: roguish[m]: Ah, so what I really need to do is swap my network configs and swap cables. Got a realtek in a slot and an intel in the mobo.
06:35 PM Bleepshop: What's a good reliable chipset to look for so I can get a replacement for the r8168??
06:39 PM roguish[m]: try the on board Intel for your mesa connection. and the realtek for regular networking stuff.
06:39 PM Tom_L: make sure about that intel setting.. i forget exactly what it is
06:41 PM skunkworks[m]: https://www.youtube.com/shorts/shorYd_f6j0
06:42 PM roguish[m]: turn IRQ coalecing off (this is in the hm2_eth man page)
06:42 PM Tom_L: yeah that
06:43 PM roguish[m]: straight from my chat with pcw
07:03 PM Bleepshop: Looking at one of these to solve the problem. https://www.amazon.com/10Gtek-Gigabit-Ethernet-Converged-Network/dp/B01LXTF48X
07:03 PM * Bleepshop is running back and forth cooking.
07:05 PM Tom_L: never seen a nic that needed a heatsink
07:06 PM Tom_L: not of late anyway
07:13 PM skunkworks[m]: server nic's - 10G usually do
07:15 PM roycroft: 10Gb nics commonly need them
07:15 PM roycroft: those things move a lot of pr0n, and need to be able to simmah down!
07:45 PM -!- #linuxcnc mode set to +v by ChanServ
08:01 PM Bleepshop: Tom_L: That's for moving those 'hot warez'. LOL
08:10 PM _unreal_: hot warez?
08:11 PM _unreal_: god I miss those days
08:11 PM _unreal_: back when the net was new
08:11 PM _unreal_: irc and DCC servers :/
08:19 PM Bleepshop: _unreal_: And grabbing Dr Who from a BBC 1 feed an hour after it aired. LOL
08:19 PM _unreal_: ? ok
08:20 PM _unreal_: I was into ps1 games/pc games of that time
08:21 PM Bleepshop: _unreal_: Starsiege Tribes and Half-Life were my PC gaming obsession then.
08:22 PM _unreal_: My one "regret" the torrent sources that use to exist. there was a torrent that had EVERY dreamcast game ISO. I had like 3 years of TOTAL shit internet back at that time frame. and was never able to download it. always pissed me off
08:22 PM _unreal_: but then again it was like 1.2TB as I recall
08:22 PM _unreal_: OH YES
08:22 PM _unreal_: I loved tribes
08:22 PM _unreal_: who knows maybe I kicked your ass a few times and same at me a few times back when
08:22 PM Bleepshop: I ws the SOB that loved to grab a dread and a nnuke and go skiing to the enemy base. LMAO
08:23 PM _unreal_: I was pushing a p200 mmx with 12meg voodoo2
08:23 PM Bleepshop: I got a Voodoo5 for the Tribes2 launch. Boy was I pissed. LOL
08:23 PM _unreal_: The one thing about tribes that alwyas ALWAYS give me shivers though. was how accurate the OH SHIT I'm out of JET pack and I'm falling
08:24 PM _unreal_: oh I had a voodoo5 best one there was. I sold it :( worst choice I ever made
08:24 PM _unreal_: some ?? 18 years ish later still eats me
08:24 PM Bleepshop: _unreal_: Lets see, ((Mass * Velocity) = "This is gonna hurt!).
08:25 PM _unreal_: heh
08:26 PM _unreal_: I never got tribes 2
08:26 PM Bleepshop: I've still got the Voodoo5 [AGP] in a drawer somewhere.
08:26 PM _unreal_: Bleepshop, You know what really kills me though.
08:27 PM Bleepshop: _unreal_: All the time you wasted gaming when there was porn to be had?
08:27 PM Bleepshop: Sorry, couldn't resist. LOL
08:27 PM _unreal_: so I'm living in my fathers house. Not my choice but he's been dealing with colon cancer for some time. but before he got bad, back at the end of 2019 the roof got replaced
08:28 PM _unreal_: and the rain gutters did not get fixed or installed
08:28 PM _unreal_: well there is a brick flower pot thing in the front of the house which is where the room I'm in is
08:29 PM _unreal_: come to find out. there is some means that water was getting into the house because of it. so when it rained it was filling and the water was getting into the house
08:30 PM _unreal_: well I had a box with my PCGAMER mags. from 1992 to 2006 I had every single pcgamer, and every "pcgames" mag there was. with all the disks and everything
08:30 PM _unreal_: because of where it was. I didnt know because it was covered. but it got SOAKED and destroyed EVERY SINGLE ONE.
08:30 PM _unreal_: killls me
08:30 PM _unreal_: it was one of my FEW prized possessions VERY few
08:30 PM _unreal_: :(
08:34 PM CloudEvil: :/
08:36 PM XXCoder: i remember restroom developing a leak
08:36 PM XXCoder: and it rusted ibm xt cases
08:36 PM XXCoder: I wanted to make fake ibm xt then dammit lol
08:37 PM XXCoder: it would be pretty lot of money now too
08:43 PM Bleepshop: I had every issue of Omni, read once and then bagged. Relatives decided to clean out my storage at Granddad's without telling me. They're still on my shit-list 25+ years later.
08:44 PM Bleepshop: roycroft: I need you to run over to Springfield and take a dump on somebodies doorstep for me. LMAO.
08:44 PM XXCoder: I can do it. one billion usd
08:44 PM Bleepshop: And yes that's directly related.
08:45 PM _unreal_: oh here is a good one for ya
08:45 PM _unreal_: back when I was in the single digits. I had a voltron action figure
08:45 PM Bleepshop: One Minion doll hair? You can have the whole damn doll. :D
08:46 PM _unreal_: that had all 5 cats, all 5 transformed and linked. that freaking thing is like $10k today. My mom/stepdad decided I was too old for it and just tossed it out one day when I was at school
08:46 PM _unreal_: did a bunch of that shit to me
08:46 PM XXCoder: me? what toys? lol grew up too poor to have em
08:47 PM _unreal_: one of the few things I caught and still have "thank you very much asshwoles"
08:47 PM _unreal_: I still have the nintendo hot seat
08:48 PM _unreal_: I have one of these only its jet black
08:48 PM _unreal_: https://www.youtube.com/watch?v=fvws5tOHsEE
08:48 PM Bleepshop: _unreal_: I can relate. Anything I had that I really liked got 'lost' or 'broken' while I was at school. Then I got into electronics and started leaving charged 100uF/200V capacitors strewn about my room.
08:52 PM Bleepshop: I think the Winshurst machine with the connected Jacob's Ladder and the Leyden jars were the kicker that convinced her to leave my room alone.
08:54 PM Bleepshop: Amazing what a kid can build out of old mayonaise jars, some junk and scratched Beethoven LPs. >:)
09:00 PM _unreal_: hum
09:01 PM * Bleepshop considers it was probably a good thing for Mom that fissionables were outside the budget.
09:20 PM roycroft: unless your family name is "kim", aren't fissionables usually out of the budget?
09:23 PM _unreal_: I was thinking something along those lines
09:23 PM roycroft: i think it's something santa just doesn't deliver on
09:30 PM Bleepshop: You'd be surprised. I grew up with a copy of this https://www.gutenberg.org/ebooks/12655 and access to scrap from NASA.
09:31 PM XXCoder: maybe this santa can https://scienceandink.com/screen_res/nz225.jpg
09:31 PM XXCoder: https://scienceandink.com/tsanta.html info lol
09:34 PM isaacggw[m]: Cool, thanks. I’m assuming that is a printed part and not a sheet metal part?
09:35 PM ZincBoy[CAON][m]: Yes, 3d printed. There is next to no force on the encoder so it just needs to hold it in place. I use CF-nylon but PETG would work fine.
09:35 PM isaacggw[m]: Cool
09:36 PM isaacggw[m]: I’ll print something like that on a poly jet at my work
09:36 PM ZincBoy[CAON][m]: That will work fine. Just want to avoid PLA due to the slightly elevated temperatures around the motor.
09:37 PM * isaacggw[m] uploaded an image: (1261KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/TyKAIdmqEvyxmWjyiRFtwbff/IMG_1025.jpg >

09:38 PM isaacggw[m]: The cheap touch probe I ordered arrived
09:38 PM isaacggw[m]: I’m confused about why there are three wires
09:38 PM ZincBoy[CAON][m]: Probably lights up.
09:38 PM isaacggw[m]: I thought it was just a switch
09:38 PM isaacggw[m]: How would you guess I wire it up?
09:38 PM isaacggw[m]: I have it hooked up to a multi meter and I flip the probe back-and-forth
09:39 PM isaacggw[m]: There is no continuity on any of the wires
09:39 PM XXCoder: postive, ground and signal is my guess
09:39 PM XXCoder: no paper?
09:39 PM ZincBoy[CAON][m]: I would try red to VCC, black to GND, and see what happens on yellow
09:39 PM ZincBoy[CAON][m]: Might be open collector output and need a pullup
09:39 PM ZincBoy[CAON][m]: Do you know what voltage it is spec'd for?
09:40 PM ZincBoy[CAON][m]: If you have a current limited power supply, I would start with that.
09:42 PM Bleepshop: isaacggw[m]: Red +, Black -, Yellow signal. Take a couple of LEDs and 2.2k resistors and tie one either way from the signal lead.
09:43 PM Bleepshop: Tie from signal to +/- and then try the probe. One LED should go out and the other one should get brighter.
09:43 PM isaacggw[m]: Says 5 to 24 V
09:44 PM Bleepshop: Testing for NPN/PNP output.
09:44 PM isaacggw[m]: Ok, I’ll try that
09:44 PM Bleepshop: I'd go 12V with the 2.2K or 1K at 5V.
09:45 PM isaacggw[m]: Here is the link to where I bought it: https://www.amazon.com/Professional-Accuracy-Electronic-Coordinate-Equipment/dp/B0B7RZY7HS/ref=asc_df_B0B7RZY7HS/?tag=hyprod-20&linkCode=df0&hvadid=598351571702&hvpos=&hvnetw=g&hvrand=8297581032552114112&hvpone=&hvptwo=&hvqmt=&hvdev=m&hvdvcmdl=&hvlocint=&hvlocphy=9032158&hvtargid=pla-1851736836202&psc=1
09:46 PM ZincBoy[CAON][m]: Yup. See the 6th picture in the link
09:46 PM ZincBoy[CAON][m]: Red goes to 5-24V
09:46 PM Bleepshop: isaacggw[m]: And there's all the data you need in the sixth picture.
09:46 PM ZincBoy[CAON][m]: Black goes to gnd
09:46 PM ZincBoy[CAON][m]: Yellow goes to the IO.
09:46 PM isaacggw[m]: Ok
09:48 PM isaacggw[m]: And can I probe with it straight in the default LinuxCNC gui or do I need to install some additional packages?
09:49 PM DigitalReaper: make sure your IO can handle whatever voltage you're supplying to the probe
09:50 PM ZincBoy[CAON][m]: Well, the G38.n codes will work once it is connected to motion.probe-in in the HAL.
09:53 PM isaacggw[m]: Cool
09:54 PM isaacggw[m]: Thanks for answering all my stupid questions (I am a mechanical engineer)
09:59 PM Tom_L: isaacggw[m], also..
