04:21 AM JT-Cave: morning
04:52 AM Tom_L: morning
07:36 AM JT-Cave: roguish[m], click Help > Check for Updates
08:15 AM JT-Cave: windy here today
09:53 AM coralgoat: I am working on getting a 3 axis cnc router set up.
09:53 AM coralgoat: I am also under the impression that there would be things that Linuxcnc can do the grbl would not be able to do.
09:54 AM coralgoat: I was curious what extra functionality I would get with Linuxcnc over the functionality I could get from grbl?
09:56 AM ZincBoy[CAON]066: https://forum.linuxcnc.org/38-general-linuxcnc-questions/38507-linuxcnc-vs-grbl
09:57 AM ZincBoy[CAON]066: TLDR: for a simple 3 axis basic router, not much.
10:01 AM Loetmichel: coralgoat: for once it can move in all three axis simultaneously, while grbl has problems with moving Z while moving x and y, especially when vastly different acceleration/max speeds involved
10:02 AM Loetmichel: secondly LinuxCNC has a much better and clearer gui with the chance to SEE what is happening, including stopping a task when a bit breaks and resume it at a different point in the gcode easily
10:02 AM Loetmichel: also the chance to upgrade to better things than an LPT port for step generation if your CNC gets faster.
10:04 AM coralgoat: ZincBoy[CAON]066, thanks for sharing that link.
10:05 AM coralgoat: Loetmichel, thanks
10:07 AM coralgoat: Loetmichel, "if your CNC gets faster" would be if I upgraded the motors and motor drivers?
10:07 AM coralgoat: "better things than an LPT port" like hardware from measus.com?
10:08 AM Loetmichel: coralgoat: for example, or alinged things better you less torque is needed to move.
10:09 AM Loetmichel: no, things like MESA cards, which is basically an DSP on a multi-IO board and can put out MUCH higher step rates than any PC with LPT or GRBL on an 8 bit micro can
10:09 AM Loetmichel: even integrated servo loops on the card IIRC
10:28 AM t4nk_freenode: and the thread isn't really convincing to me either
10:28 AM t4nk_freenode: you can do anything you want with grbl
10:28 AM t4nk_freenode: yes.. you do need to know how to code ;)
10:28 AM t4nk_freenode: I still like to mess with linuxcnc though
10:29 AM ZincBoy[CAON]066: While that is theoretically possible, it is vastly easier to build complex systems with linuxcnc than grbl.
10:30 AM * JT-Shop2 finishes up hanging the Starbar's
10:30 AM t4nk_freenode: grbl isn't for high-end and super techy systems, no
10:34 AM ZincBoy[CAON]066: Then saying that you can do anything you want with GRBL is a bit disingenuous. I agree that for basic 3 axis machines, LinuxCNC and GRBL are functionally interchangeable.
10:35 AM t4nk_freenode: well, 3-axes were the starting point today
10:37 AM t4nk_freenode: and from that viewpoint, I find grbl darned impressive, able to run from a tiny mcu
10:41 AM travis_farmer853: How is grbl not on an 8bit mcu? Most arduino boards are 8bit...
10:41 AM pcw--home: grbl can run on 32 bit micros
10:42 AM ZincBoy[CAON]066: Grbl is impressive but the MCU has quite a bit more processing power than the original control in my mill. The original CPU was an 8086 clocked at a blazing 8MHz and with much lower IPC than a modern MCU. With that they had the full 4 axis control and GUI.
10:42 AM t4nk_freenode: yes, it can run on 8-bit too, another advantage... but nobody in their right minds would want to these days
10:44 AM t4nk_freenode: lol, ZincBoy[CAON]066, I know.. but that mcu is the simplest one can buy for $1,35 these days :))
10:46 AM t4nk_freenode: (my ender3 has an 8-bit mcu, oh the pain!)
10:48 AM ZincBoy[CAON]066: Yes, I can't think of any reason to use a 8bit mcu these days other than inertia or when you need a _really_ small one. I was using ARM based 32 bit MCUs that cost ~$1 and it made things so much easier than having to tweak code to work in the limits of an 8 bit system. Unfortunately with the recent supply chain issues the prices on all of these have gone through the roof.
10:51 AM t4nk_freenode: for a lot of applications it is just tremendous overkill, that is a fact I really don't like at all, deep in my heart
10:52 AM t4nk_freenode: but that has been the general evolution, unfortunately
10:52 AM ZincBoy[CAON]066: Agreed, but the faster development time is hard to pass up.
10:53 AM t4nk_freenode: yeah, that is simply awesome
10:58 AM unterhaus: I guess I don't really need my collection of 8748 any more
11:13 AM ZincBoy[CAON]066: I finally got rid of my 68Hc11 dev systems
11:37 AM t4nk_freenode: hey, ZincBoy[CAON]066, this is not meant as an attack, .. but I was thinking.. how many linuxcnc user would actually be using the kind of machines for which grbl would be less suited
11:37 AM t4nk_freenode: I have 4 axes, but only because y is gange
11:37 AM t4nk_freenode: d
11:42 AM t4nk_freenode: my rebuild is almost done; still need to figure out how I'm gonna attach the limit switches for x and y
11:45 AM ZincBoy[CAON]066: To be honest, not many. The big advantages of LinuxCNC is its open nature and ease of creating complex systems. The Mesa ecosystem is also really hard to beat and I haven't found anything comparable. If you just want to run a 3 axis machine then grbl may be a good choice for you. Similarly Mach3 would also be a good choice. I have looked quite hard at alternatives to LinuxCNC as one of its weaknesses right now is the motion
11:45 AM ZincBoy[CAON]066: planner (no jerk or higher order control). There really isn't anything until you get to paid systems like Fanuc or Siemens.
11:46 AM t4nk_freenode: right, that's what I was thinking too; they'd probably have proprietary stuff, along with service contracts and so on
11:47 AM t4nk_freenode: makes me think of some vid I saw where an entire engine block was milled in like 10 minutes or so
11:48 AM t4nk_freenode: mind boggling
11:54 AM ZincBoy[CAON]066: I looked at getting a Siemens control for my mill but at over $25k it really wasn't worth it.
12:44 PM -!- #linuxcnc mode set to +v by ChanServ
01:14 PM Loetmichel: t4nk_freenode: well, if you can program its not a problem at all: if it doesent fit , just write your own Program that does what you want. To my knowledge and experience GRBL has problems with more than two axis running simultaneously. It may be because i never ran across a GRBL on anything but AVRs or similar underpowered 8bit MCUs. Also the aviable "GUI"s on the sending PC are gruesome
01:14 PM Loetmichel: and no comparsion to axis or similar.
01:15 PM Loetmichel: Also i would appreciate to not call me "liar" and then go silent again, i would rather see that YOU give him more detailled information if you think you are so knowledgeable about it.
01:16 PM t4nk_freenode: ? did I call you liar? I don't think so
01:16 PM t4nk_freenode: but I'm having dinner atm
01:16 PM roycroft: simmah down :)
01:17 PM Loetmichel: You basically stated "nothing you said is true" and then scampered off again. but anyways, i said my piece. Do what you like.
01:17 PM c101horse8332[m]: how about the csmio stuff?
01:18 PM t4nk_freenode: Loetmichel, I said something at 1700pm, and was chatting with ppl here for two hours
01:18 PM t4nk_freenode: I wouldn't call that scampering off
01:19 PM XXCoder: sorry, but what does 1700pm even mean?
01:19 PM t4nk_freenode: double-evening
01:20 PM unterhaus: I really like grbl, but it's pretty limited. And when I looked at the current marlin it seems much harder to configure than lcnc
01:21 PM unterhaus: marlin is pretty amazing though, seen it doing corexy at 20m/s
01:22 PM XXCoder: grbl is great for tiny boards, for 2 axis
01:22 PM XXCoder: my laser machine uses grbl
01:22 PM XXCoder: ohh interesting idea https://www.reddit.com/r/3Dprinting/comments/utwghv/first_time_printing_and_using_a_set_of_custom/
01:23 PM ZincBoy[CAON]066: Systems like that or the Centroid stuff don't have enough IO and are limited to step/dir control. I am using the original analog servo drives and all of the tool changer PLC is handled by linuxcnc. I am also doing some custom control for the spindle VFD to orient the spindle. These systems work great on typical 3/4 axis machines but really can't handle a full machining center. LinuxCNC gets the closest without going to $$$$.
01:24 PM unterhaus: it's funny how people that criticize lcnc always bring up the parport given that it was a clever hack
01:24 PM c101horse8332[m]: my brother went with csmio on his hurco, lcnc looked like too much of a hassle to him and his mate
01:24 PM c101horse8332[m]: running atc aswell
01:25 PM unterhaus: it's cool that you can use a parport or another interface, but the fact that you can use a parport doesn't work as a criticism of lcnc
01:27 PM unterhaus: but if you want to run 4 axis on a grbl cnc shield, you can hook it up to lcnc, but it doesn't work with grbl
01:32 PM ZincBoy[CAON]066: It really depends on the machine. I need over 100 IO on mine and it is pretty small. LinuxCNC also lets me do things that are impossible on other controls with custom real-time components. Someone with no linux experience may well be better off with a canned solution that has paid support. Unless your hobby is building CNC machines, you just want it to work and not deal with finding low latency computers and the like.
01:33 PM t4nk_freenode: it's certainly an extra dimension to have your very own build
01:34 PM t4nk_freenode: most of the fun for me, actually
01:35 PM MikeM5072[m]: When I was building my CNC, i took a pretty deep look at all the boards and controller software. It came down to it met my requirements and was the most mature and supported controller system out there. I thought it was very easy to setup especially when I was 100% new to CNCing. It supporting parport was never a detractor as other platforms also support parport.
01:36 PM Tom_L: ZincBoy[CAON]066, what sort of mill do you have?
01:36 PM Tom_L: and do you use it commercially?
01:38 PM travis_farmer853: my first lcnc build-up used a parport... then i saw that there was something better, and went with a Mesa 7i80HD-16, and am very happy with lcnc 🙂
01:38 PM Tom_L: travis_farmer853, what daughter cards?
01:39 PM travis_farmer853: bare breakout boards, and external opto-isolation
01:42 PM ZincBoy[CAON]066: Hitachi-Seiki VK45. I do side jobs on it to pay for tooling and materials for fun but not really in a commercial way. https://www.youtube.com/watch?v=1fNQw3LNJa0
01:46 PM roycroft: my personal goal is to make parts
01:47 PM roycroft: building the machine that makes the parts, while fun and interesting, is secondary
01:47 PM roycroft: or, in my case, building the machine that makes the jigs that help make the parts
01:50 PM unterhaus: a lot of the inexpenisve cnc routers use grbl, so it's certainly capable
01:53 PM unterhaus: biggest problem with it can be solved with a usb isolator
01:53 PM t4nk_freenode: well, ZincBoy[CAON]066, that's some machine...
01:53 PM MikeM5072[m]: I found GRBL to be limiting
01:54 PM XXCoder: its good on its problem space. but yeah
02:01 PM MikeM5072[m]: So, I know this isn't LinuxCNC specific, so forgive me if this is off topic. I did build my own machine, and so far I have it running pretty solid. I am using a Mesa 7i96. What I have noticed is if I run another machine (band saw, sander, etc.,) while it is running, at least one of the steppers seems to skip a step. The machines are on separate circuits. Wiring to the steppers is shielded. Any thoughts as to why this may happen?
02:02 PM XXCoder: we often talk about MESA and machining here so no problem!
02:02 PM unterhaus: definitely sounds like electrical noise. Poor ground bonding? Ground loops in the control cabinet?
02:03 PM hazzy[m]: I would suspect noise on the signals to the stepper drivers
02:04 PM MikeM5072[m]: I was pretty thorough (or at least I thought I was, lol) with grounding in the controller. Controller, alas, is still on a sheet of plywood, I am getting ready to make an enclosure for it.
02:07 PM MikeM5072[m]: The wiring between the 7i96 and the drivers is not shielded, should it be?
02:13 PM ZincBoy[CAON]066: One thing that can help in these cases are snap on ferrite beads. Like so: https://www.amazon.ca/KisSealed-Clip-Ferrite-Suppressor-Diameter/dp/B0989RV2DN/
02:13 PM ZincBoy[CAON]066: I used a ton of these and it really helps with common mode noise rejection.
02:15 PM MikeM5072[m]: Thank you, I will give those a try!
02:19 PM XXCoder: hey andypugh
02:20 PM ZincBoy[CAON]066: The other thing to look at is how you have wired your step/dir signals. I prefer to use twisted pairs to run the step+/- and dir+/-. This gives maximum noise immunity.
02:20 PM XXCoder: I want to replace main chips mascot graphics with git push, but im not sure how and if I should, andy
02:20 PM andypugh: Make a pull request rather than push direct, maybe?
02:21 PM andypugh: But then it’s likely to get lost in the others.
02:21 PM andypugh: So just push it :-)
02:21 PM XXCoder: ok. though im not sure about other formats, like .ai. need to look if inkscape can export those
02:22 PM XXCoder: i also want to move old version to logos folder
02:23 PM MikeM5072[m]: ZincBoy, thanks, right now i have single wires running to each pin. I believe I have enough of the shielded/twisted wiring left over that I can switch to that fairly easily.
02:32 PM MikeM5072[m]: Thank you again for your help! It has been a lot of fun building this CNC and overall it seems to work really well!
02:36 PM ZincBoy[CAON]066: You are welcome. The main thing to remember is that ground loops are bad and you ideally want everything grounded to one point.
02:38 PM MikeM5072[m]: I have a grounding block that everything runs back too, each part has its own wire back to the block.
02:40 PM XXCoder: mike nice. got pictures? curious
02:41 PM * MikeM5072[m] uploaded an image: (7594KiB) < https://libera.ems.host/_matrix/media/r0/download/jauriarts.org/OHnqylJNKsUsfiZIftwzZeDS/20220219_210640.jpg >
02:42 PM XXCoder: https://imgur.com/j9ppK99.png made this example for milling and wanting to fit square something in without having to finish corners with different tools
02:42 PM XXCoder: 0.6 mm rad can be any other radius of tool really
02:42 PM sliptonicBradCol: If generating gcode with FreeCAD, use dogbone dressup
02:44 PM sliptonicBradCol: The dressup lets you pick a bone style to control which direction it overcuts. That can let you hide the overcuts if you have an overlap in one direction but not the other

02:45 PM MikeM5072[m]: Those are some pics of the machine, and the controller while I was still working on putting it together.
02:46 PM XXCoder: mike nice! kinda reminds me of that old 2'x3' cnc royter project
02:46 PM MikeM5072[m]: I am working on designing the enclosure for it now
02:46 PM MikeM5072[m]: Thank you!
02:47 PM XXCoder: sliptonicBradCol: nice didnt know it existed. never really worked with freecad cam
02:47 PM XXCoder: that guy sold design to some company and deleted howto. thankfully I had downloaded entire thing
02:48 PM XXCoder: funny because the company closed down if I recall right. so it dont exist anywhere
02:48 PM MikeM5072[m]: As I said, overall it works well, and I have been starting to gradually push it to faster speeds and so far it seems solid!
02:48 PM XXCoder: bit obselete design really, it uses steel plates for rails. we have cheap MGN and SBRs now
02:48 PM XXCoder: mike thats awesome
02:49 PM MikeM5072[m]: All the rails on my machine are SBR20, and all driven by ball screws.
02:50 PM XXCoder: how thick is screws?
02:50 PM XXCoder: what I can see, its reasonable
02:50 PM MikeM5072[m]: 16mm I believe
02:51 PM XXCoder: yeah. seen people use 12mm. I could see it whup as it moves axis
02:51 PM XXCoder: it was as wide as yours was long and yeah whupping a lot
02:52 PM MikeM5072[m]: Have not noticed that at all on the Y Axis. I also went with double screws on the Y Axis.
02:52 PM unterhaus: MikeMbunchanumbers you probably need to clean up that controller wiring. It might work even on plywood
02:52 PM ZincBoy[CAON]066: MikeM (@_discord_854784589033898004:jauriarts.org) nice machine. I don't know how much the wiring has changed in your current setup. In the picture you could improve the seperation between the power and control signals.
02:52 PM unterhaus: I was about to mention, power needs to be separated from signal
02:53 PM unterhaus: power inputs and stepper outputs
02:54 PM ZincBoy[CAON]066: Twisting the power leads to the drives can help quite a bit as well.
02:54 PM MikeM5072[m]: I am getting ready to make an enclosure for it, i can definitely clean up the wiring when I do that.
02:55 PM unterhaus: it looks like your wiring to the stepper connectors goes right through everything
02:55 PM unterhaus: so there is crosstalk there
02:55 PM ZincBoy[CAON]066: It is good you have dedicated blocks for power+/- and gnd. You don't seem to be daisy chaining things and that is a good thing.
02:55 PM unterhaus: and that part isn't sheilded
02:57 PM CaptHindsight[m]: https://www.reddit.com/r/Machinists/comments/utob72/nightshift_shenanigans/ amateurs
02:57 PM ZincBoy[CAON]066: unterhaus, they are not running in parallel for any distance so the crosstalk should be minimal but it is definitely best to separate them as much as possible. if they got ziptied together at some point that would be bad 🙂
02:59 PM MikeM5072[m]: Thank you for the advise on the wiring. It was definitely my first go on building a controller for a CNC, and I have very little electronics back ground, so I am sure there is definitely room for improvement!
02:59 PM CaptHindsight[m]: I regularly have stepper drives scattered about the bench next to a machine under development without issues
03:00 PM CaptHindsight[m]: some cheap stepper drives are just really noisy and jerky
03:01 PM roguish[m]: shielding is really good. distance is better. use both. belts and suspenders.....
03:01 PM MikeM5072[m]: I am using the KL-5056 drivers from automation technologies.
03:02 PM CaptHindsight[m]: MikeM#5072: what gauge ground and power wires?
03:03 PM CaptHindsight[m]: I've used a bunch of the automation technologies drives in the past, I don't anymore. Evne thouigh he is local
03:03 PM CaptHindsight[m]: s/Evne/Even/, s/thouigh/though/
03:05 PM MikeM5072[m]: I am using 18awg
03:06 PM roycroft: i got another 10 pair of drawer slides installed at lunch
03:07 PM roycroft: including in that set of holes that were misdrilled
03:07 PM roycroft: my fix worked great
03:07 PM CaptHindsight[m]: MikeM#5072: which power supply for the stepper drives? Also from A.T.?
03:08 PM CaptHindsight[m]: KL350-36 ?
03:09 PM MikeM5072[m]: Yes and the KL-10-5
03:11 PM CaptHindsight[m]: he's a nice guy but I stopped buying his parts, too many problems, just due to being poorly made
03:11 PM CaptHindsight[m]: his biggest headache as well, QC
03:12 PM MikeM5072[m]: I had a couple people recommend him, and so far everything I got from him has worked without issue.
03:13 PM MikeM5072[m]: All 4 steppers are the NEMA23 382oz/in 3.0A Stepper Motor 1/4 Dual shaft (KL23H2100-30-4B)
03:14 PM CaptHindsight[m]: other suggestions that might help, using larger power conductors, adding a capacitor to the stepper drives, double check all you wire routing, use best practice as was mentioned earlier
03:15 PM CaptHindsight[m]: I have 10+ year old parts from him
03:15 PM CaptHindsight[m]: started swapping out his parts a few years ago from machines that just got noisy
03:16 PM CaptHindsight[m]: some of it is just getting the lucky better parts
03:16 PM XXCoder: roycroft: nice on drawer
03:17 PM MikeM5072[m]: Again, thank you. I will likely rewire everything when I move to the new enclosure for the electronics
03:17 PM CaptHindsight[m]: sometimes I got bearings with detents in them and linear bearings with what might have been sand in them :)
03:19 PM GTKplusplus6432[: https://cdn.discordapp.com/attachments/700372690870992978/977293380440719400/20220520_213441.jpg... (full message at https://libera.ems.host/_matrix/media/r0/download/libera.chat/73bed6ff2158fa0cb719d380d7c31a836f2debc0)
03:19 PM GTKplusplus6432[: I could see it being lead in related but the code was the exact same,so it should have done that the first time too, shouldn't it?
03:22 PM ZincBoy[CAON]066: Cutter comp is sensitive to both lead in and out. Making the tool smaller shouldn't usually be a problem. Did you re-run the whole program or just the section?
03:23 PM GTKplusplus6432[: whole program
03:23 PM CaptHindsight[m]: GTKplusplus#6432: run it without any materials both ways and see what it does
03:24 PM GTKplusplus6432[: I already turned the machine off and left the shed
03:24 PM GTKplusplus6432[: however, I ran it above the part a couple time with tool at nominal diameter and it didn't have any issues
03:24 PM CaptHindsight[m]: next time to test
03:24 PM GTKplusplus6432[: what do you mean both ways, btw?
03:24 PM GTKplusplus6432[: both directions of cutter comp?
03:24 PM CaptHindsight[m]: 6.0and the 5.95
03:24 PM GTKplusplus6432[: ah
03:24 PM CaptHindsight[m]: before and after the change
03:25 PM CaptHindsight[m]: but you have a few examples of the "before the change"
03:25 PM GTKplusplus6432[: well, given that before I changed the parameters it worked and as soon as I did it didn't, I coudl rerun it but I don't know what I should learn
03:25 PM GTKplusplus6432[: before the change it worked exactly as expected
03:25 PM CaptHindsight[m]: so now test what it does after
03:26 PM GTKplusplus6432[: will do next time
03:26 PM GTKplusplus6432[: had a weird behaviour after I estopped too, in that the Y1 motor stopped working when I homed the machine
03:26 PM GTKplusplus6432[: but I'm guessing that's an electrical gremlin of some kind I need to track down
03:26 PM CaptHindsight[m]: fun
03:27 PM GTKplusplus6432[: especially on my control panel
03:27 PM GTKplusplus6432[: which has a door that falls on my head when I work on it
03:27 PM GTKplusplus6432[: * especially on my electronics cabinet
03:27 PM CaptHindsight[m]: feature or bug?
03:28 PM GTKplusplus6432[: only cabinet I could get my hands on
03:28 PM CaptHindsight[m]: I used to have a cup and spoon that would poke me in the eyes :)
03:28 PM GTKplusplus6432[: meaning, when I send him to buy one when I was busy he came back from this piece of shit from the scrapyard
03:28 PM GTKplusplus6432[: s/from/with/
03:29 PM GTKplusplus6432[: and then we realized we could only put it on the machine horizontally if I wanted space for the gx16 connectors
03:29 PM GTKplusplus6432[: so... yeah, bug
03:29 PM GTKplusplus6432[: one of many from my list of compromises
03:30 PM travis_farmer853: my control cabinet is just a network rack enclosure, that is wall hung... kinda deep to work in sometimes. thinking if layering the power supplies behind the controls...
03:31 PM CaptHindsight[m]: travis_farmer#8534: be aware of airflow back there
03:32 PM travis_farmer853: yeah, i would build it like a top to bottom tunnel, with vent fan for air-flow
03:32 PM CaptHindsight[m]: I got a machine from someone that though it was fine to place two large power supplies in a "just fits" plastic enclosure
03:33 PM CaptHindsight[m]: s/though/thought/
03:33 PM travis_farmer853: ouch...
03:34 PM CaptHindsight[m]: was also airtight except for the 3/4' conduits filled with conductors
03:34 PM ZincBoy[CAON]066: One thing if you have a deep enclosure is to use drawer slides to create slide out plates. It can give a bunch more room without sacrificing maintainability or air flow. Picture from my lathe build:

03:35 PM travis_farmer853: that is exactly what i want to do, but couldn't figure out how to manage the wiring so the plates could slide out
03:37 PM ZincBoy[CAON]066: There is a slack loop at the back that lets the plates move out. The cables are zip tied together in a flat ribbon. Works quite well for something that does not move all the time.
03:37 PM travis_farmer853: Hmm, defiantly food for thought
03:39 PM travis_farmer853: enclosure has side access panels, so that would make rear wiring easier...
03:39 PM CaptHindsight[m]: or like you see cablechain on a x and y axis
03:39 PM travis_farmer853: true
03:39 PM MrSunshine: do i spy an intel 510mo ? =)
03:39 PM CaptHindsight[m]: https://www.automationdirect.com/adc/search/search?fctype=adc.falcon.search.SearchFormCtrl&cmd=Search&searchquery=stepper+drives&categoryId=0&TxnNumber=-1&searchqty=10#Item_Type_ms=(%22Stepper%20Drive%22)&start=0&rows=10&Brand_Name_ms=(%20%22SureStep%22)
03:39 PM MrSunshine: nope, it does not have a parport on it
03:40 PM MrSunshine: damn .. but something close to it =)
03:40 PM CaptHindsight[m]: big difference in behavior between the SureStep's and the Leadshines
03:41 PM travis_farmer853: i have leadshine... are they better or worse?
03:42 PM CaptHindsight[m]: the Suresteps are near silent in most modes similar to the Geckos
03:43 PM travis_farmer853: figures, i bought what i could afford... but hey, they work for now 🙂
03:43 PM CaptHindsight[m]: but the prices is also 2X the Leadshine, like the Geckos
03:43 PM ZincBoy[CAON]066: It is a Intel D525MW motherboard
03:45 PM CaptHindsight[m]: travis_farmer#8534: there are people that use the tb6560 and similar, that have working machines, just noisy
03:46 PM CaptHindsight[m]: I don't think I have ever heard a noisy drive than the TB65xx's
03:46 PM travis_farmer853: i kinda like the noise. like the steppers are making their own music. when i get sick of it, i will upgrade 😉
03:51 PM c101horse8332[m]: you people hear the steppers over the machining?
03:52 PM travis_farmer853: not when my 5HP 22K rpm spindle is at speed 😉
03:57 PM CaptHindsight[m]: c101horse🇳🇱: TB65xx's drown out jet take offs
03:57 PM CaptHindsight[m]: even scares off insects
03:58 PM c101horse8332[m]: i dont know what i've got, some unmarked chinese drivers
03:58 PM XXCoder: being deaf it doesnt affect me lol. I use BoB and tb6600s, but want to use rpi4, MESA board of some kind, and probably better drivers
04:00 PM MrSunshine: ZincBoy[CAON]066, i was close then =) looked just like my 519mo except for the parport =)
04:00 PM XXCoder: and definitely better steppers! ones on my router is weaksauce
04:41 PM Centurion_Dan1 is now known as Centurion_Dan
04:49 PM Tom_L: ZincBoy[CAON]066, what are the small boards below the gecko drivers?
04:49 PM Tom_L: optos?
04:49 PM XXCoder: yo jt
04:50 PM Tom_L: i recognize the MB.. i have one
04:50 PM ZincBoy[CAON]066: Yes, they isolate the fault output of the drive so it can be fed back to the mesa card.
04:50 PM JT-Shop2: yo
04:51 PM Tom_L: nice layout..
04:54 PM ZincBoy[CAON]066: Thanks. It isn't quite as clean and tidy after 10 years but it is still running fine.
04:55 PM XXCoder: slide out is nicely done, for repairability viewpoint
04:57 PM ZincBoy[CAON]066: Yes, makes it really easy to debug.
04:57 PM ZincBoy[CAON]066: Some parts I just made on the lathe:

04:58 PM ZincBoy[CAON]066: The original oil valves are on the left. The new ones have the torx socket.
04:59 PM XXCoder: broached or milled tork socket?
04:59 PM Tom_L: mine looks like crap but runs great
04:59 PM ZincBoy[CAON]066: Milled. It is a T55 so easy to do.
04:59 PM XXCoder: reminds me of my old car lol. looked like it was left in yard for 10 years
04:59 PM XXCoder: ran like new
05:00 PM Tom_L: what cutter did you use for the torx ?
05:00 PM XXCoder: interestng
05:01 PM XXCoder: broaching is something I might be able to work on even when permently dizzy
05:01 PM XXCoder: deafness is a bonus since I hear its very loud
05:02 PM ZincBoy[CAON]066: 1/16" end mill. Put it in the spindle speeder so I could run it at 20k rpm. Still was the slowest part of the operation.
05:03 PM Tom_L: mine is a more conventional style mill built all from scrap
05:07 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Spindle/Control_Pannel1.jpg
05:08 PM Tom_L: since added a stepper to the rotary
05:10 PM ZincBoy[CAON]066: Looks pretty good! Is that a sherline spindle?
05:10 PM Tom_L: yes
05:10 PM Tom_L: i had a sherline prior and used that from it
05:10 PM Tom_L: had the motor on too until i got the BLDC
05:11 PM XXCoder: you need to have 3d printers for building misc stuff for machine lol
05:11 PM XXCoder: like cover for spindle belt
05:11 PM Tom_L: sheet metal
05:11 PM XXCoder: for that one I guess so, but theres other uses
05:11 PM Tom_L: i had one and it just kept getting in the way
05:11 PM ZincBoy[CAON]066: One suggestion is to put an estop button where you normally have your hands. I recently learned that lesson when I reached for a stop button that was in the path of the machine.
05:12 PM Tom_L: i have one on the pendant as well
05:12 PM Tom_L: i use it alot more than anything else
05:12 PM Tom_L: it's generally in hand unless i've proved things out
05:13 PM Tom_L: i used to run large cncs and did this one because i missed it :)
05:13 PM Tom_L: tested alot of lcnc features on it
05:14 PM ZincBoy[CAON]066: That is good. I was used to reaching for this button and had an issue when things went bad. Did some damage to my hand so now I am looking at the ergonomics of my machines from a safety standpoint.
05:14 PM Tom_L: i added that to the pannel recently just for completeness. it's never been used
05:15 PM ZincBoy[CAON]066: You can never have too many big red buttons 🙂
05:15 PM XXCoder: yup
05:16 PM XXCoder: I want one, had to hit etc couple times one time because part was breaking (test run went bad, my fault)
05:16 PM XXCoder: it suck to grab keyboard and try hit etc
05:16 PM XXCoder: *esc
05:16 PM Tom_L: https://www.youtube.com/channel/UCoG_JaILNz3Q-jBZ5MiK1dA
05:16 PM Tom_L: you can see some of the tests there
05:16 PM Tom_L: not edited...
05:17 PM Tom_L: the A axis is there
05:17 PM XXCoder: you can see how very bad my setup was https://www.youtube.com/watch?v=oQUSS9FO9kY
05:18 PM Tom_L: was?
05:19 PM Tom_L: does it still work?
05:19 PM XXCoder: its been in my closet for last 3 years
05:19 PM XXCoder: no room to setup it ever since I moved
05:19 PM Tom_L: time to get it out!
05:19 PM XXCoder: https://www.youtube.com/watch?v=sojJgCfDbp4 more secure, but was waaay too slow for nylon. https://www.youtube.com/watch?v=sojJgCfDbp4
05:19 PM XXCoder: learned a lot since
05:25 PM JT-Shop2: hmm I might actually get the Powermatic 15HH next week
05:26 PM Tom_L: what's that newer all in one stepper card?
05:26 PM Tom_L: 7i96? i forget..
05:27 PM unterhaus: isn't it the 7i96s?
05:27 PM unterhaus: product not found
05:28 PM Tom_L: s added analog spindle support and a few other things
05:28 PM unterhaus: okay, must be a different letter then
05:28 PM JT-Shop2: 7i96S
05:29 PM unterhaus: i was right? not used to that
05:29 PM unterhaus: is it on mesa.us?
05:29 PM Tom_L: is it available?
05:29 PM JT-Shop2: https://mesaus.com/product/7i96s/
05:30 PM JT-Shop2: they are either at the assembly house or in testing
05:30 PM XXCoder: drivers for steppers included on bord?
05:30 PM Tom_L: is that the one he's using the different fpga on?
05:30 PM JT-Shop2: yep, using a fpga that doesn't have a 99 week lead time
05:30 PM unterhaus: XXCoder, no drivers
05:30 PM Tom_L: XXCoder, probably isolation for them
05:30 PM XXCoder: ok
05:31 PM unterhaus: it's mostly just a 7i96 with different fpga
05:31 PM JT-Shop2: my Mesa Configuration Tool will make the configuration files as well as many other things
05:32 PM JT-Shop2: it has two high isolation outputs useful for plasma as well as build in debounce on the inputs
05:32 PM JT-Shop2: it's a 7i96 on steroids lol
05:33 PM Tom_L: ahh... that's what the "S" is for!
05:33 PM JT-Shop2: seems to fit
05:34 PM JT-Shop2: and the debounce time is configurable
05:36 PM Tom_L: so he did it in firmware instead of hardware
05:37 PM JT-Shop2: the new fpga has more things
05:39 PM JT-Shop2: 3 cards have inmux now
05:39 PM JT-Shop2: I added all the Mesa PDF manuals that pertain to the cards in the MCT, it's cool
05:41 PM JT-Shop2: no more questions?
05:42 PM * JT-Shop2 goes to work on the coon lock
05:42 PM Tom_L: hands full of food
05:42 PM JT-Shop2: yum
05:42 PM Tom_L: multiplex inputs?
05:43 PM JT-Shop2: I think so
05:48 PM unterhaus: JT, which 3 cards have inmux?
05:52 PM JT-Shop2: 7i97 and 7i95 I think, run my Mesa Configuration Tool and if debounce is enabled they have inmux
05:54 PM JT-Shop2: my second coon lock door is 1" too long... fix that tomorrow
05:54 PM Tom_L: better that than too short
05:55 PM JT-Shop2: yep
05:56 PM JT-Shop2: https://gnipsel.com/mesa/mesact/index.html
05:56 PM JT-Shop2: roguish[m]: did you update mesact?
06:00 PM * JT-Shop2 needs to update this PC to 64bit

08:36 PM XXCoder: one of favorite posts so far lol
08:39 PM pcw--home: JT-Shop2 the regular 7I96 can have inm also
08:39 PM Tom_L: how many can you mux?
08:40 PM Tom_L: is that a better option than sserial?
08:41 PM pcw--home: inm is just in input module for GPIO (it adds hardware debounce and MPG encoder inputs)
08:41 PM Tom_L: right
08:41 PM Tom_L: but if all you need it more input is that a better choice over sserial?
08:42 PM pcw--home: inmux is the same but uses external mux chips to save pins
08:42 PM Tom_L: i see
08:42 PM pcw--home: simpler to implement
08:42 PM Tom_L: shift reg?
08:43 PM pcw--home: mux chips (74HC/HCT251S)
08:45 PM pcw--home: max pins per inm/inmux is 32
08:45 PM pcw--home: max mpgs is 4
08:46 PM pcw--home: MPGs have 1x or 4x modes
