12:59 AM Deejay: moin
01:40 AM lcnc-relay: <captainhindsight_.@> mrec: yes, they hold about 500kg
01:41 AM lcnc-relay: <captainhindsight_.@> Maybe 1,000kg with fixtures
01:41 AM lcnc-relay: <captainhindsight_.@> You can see the parts and fixtures on the right
02:14 AM lcnc-relay: <meisterdippel@> moin
02:14 AM memleak: hello!
02:30 AM memleak: brb
03:39 AM alex_joni: hi all
03:39 AM alex_joni: this thing still on?
03:47 AM lcnc-relay: <captainhindsight_.@> Nobody here but us chickens
04:24 AM Tom_L: morning
04:38 AM lcnc-relay: <travis_farmer@> Morning all... been quiet for a while due to various reasons. like my network is down out in the shop due to the cold, so i can't fire up the network controlled thermostat... and also i have been dealing with some very severe depression...
05:53 AM lcnc-relay: <captainhindsight_.@> Anyone have a source for cheap Chinese carbide drills ? Mostly 4-8mm
06:58 AM rdtsc-w: Amazon, Cap'n
12:02 PM rdtsc-w: Visit Meisterdippel - he's always working on some robot or another :)
12:18 PM jdh: Anyone know of a way to convert (and divide) quadrature encoder to CW/CCW?
12:19 PM jdh: Or a source for 750 ppr CW/CCW encoders
12:20 PM lcnc-relay: <voiditswarranty@> any quadrature encoder is capable of determining CW or CCW, depends on the program decoding it. I probably misunderstand the question
12:20 PM lcnc-relay: <voiditswarranty@> if the A phase pulse comes before the B phase pulse, it's one direection. if B comes first, it's the other direction.
12:21 PM mrec: if a magnetic encoder is an option you can adjust them via configuration especially the PPR
12:34 PM lcnc-relay: <travis_farmer@> fascinating, we talk about corvettes, chickens, and the weather, but i mention that i have been battling crippling severe depression, and get completely ignored... guess i was never really "one of the boys"...
12:37 PM lcnc-relay: <voiditswarranty@> travis_farmer@: I was gonna say "yeah me too" but the conversation had moved on. Winter with the 7 hours of daylight in the middle of it here is tough on me.
12:37 PM Tom_L: jdh, you should be able to tell by the timing of each signal if it's fwd or rev
12:40 PM lcnc-relay: <voiditswarranty@> * on and I've always been the odd one out :D. I was that kid in highschool that ignored everyone and made the robot arm in the electronics lab sharpen pencils instead.
12:42 PM lcnc-relay: <travis_farmer@> voiditswarranty@ , this is more than just seasonal... lets just say my psych doc keeps asking if i have guns...
12:42 PM roycroft: it's already not totally dark at 5pm here
12:42 PM roycroft: i'm coming out of my winter darkness depression already
12:42 PM * Tom_L thinks the channel should maybe get back on track for what it's intended for
12:42 PM lcnc-relay: <voiditswarranty@> I'm on a maintenance dose of SSRI's, it's just WAAAYY worse when somoene turns the light off in the big blue room out there
12:43 PM roycroft: i was looking at the delta printer this morning, wondering what it would take to get it working
12:43 PM roycroft: iirc folks were talking about controlling delta printers with linuxcnc a decade or so ago, but not much since then
12:43 PM roycroft: i guess it was a fad that did not last very long
12:44 PM lcnc-relay: <voiditswarranty@> * there. we as a society do indeed neglect each other's mental health while talking about other health.
12:44 PM roycroft: but i think it would be fun to play with
12:44 PM Tom_L: jdh, what sort of code are you looking for?
12:44 PM roycroft: and it appears that mechanically it's complete
12:46 PM jpa-: jdh: http://basicelectronic.blogspot.com/2006/08/rotary-encoder-converter-circuit.html
12:46 PM lcnc-relay: <skunkworks8841@> Just a little kins... All it takes...
12:46 PM lcnc-relay: <skunkworks8841@> lol
12:46 PM lcnc-relay: <voiditswarranty@> I did a delta as my first printer, I hated it! tough to get it mechanically perfect, depended on a lot of software calibration. The error function ended up with a heightmap of waves, rather than planar compensation. It could move very fast though, but even on a normal kins machine the limiting speed was the speed I could melt, not move.
12:47 PM xxcoder: kossel clear printer should have hotend issues besides that it should be complete yeah
12:47 PM Tom_L: i've done quadrature on a fpga and avr if you need to see something
12:47 PM xxcoder: it has real jhead hotend
12:47 PM lcnc-relay: <voiditswarranty@> I've got quadrature in esp-idf (all 3 main modes) if that's helpful too
12:48 PM Tom_L: that diagram shows it phase shifted more than it actually is
12:49 PM lcnc-relay: <voiditswarranty@> yeah, is't it normally 90 degrees? that looks like less
12:50 PM Tom_L: https://www.youtube.com/watch?v=o8lezpJhfAo
12:50 PM lcnc-relay: <voiditswarranty@> in practice I don't think it matters much, I usually count rising and falling edges
12:50 PM lcnc-relay: <voiditswarranty@> +and sample several for rpm and such
12:54 PM lcnc-relay: <andypugh@> Minimal (fast) interrupt based encoder counter for Arduino:
12:54 PM lcnc-relay: `// lookup table for encoder transitions
12:54 PM lcnc-relay: int encoder_states[] = {0, -1, 1, 0, 1, 0, 0, -1, -1, 0, 0, 1, 0, 1, -1, 0};
12:54 PM lcnc-relay: void IRAM_ATTR countE1(){
12:54 PM lcnc-relay: ... long message truncated: https://jauriarts.org/_heisenbridge/media/jauriarts.org/TfSNZpbAFDJHSQqcrJBszmCK/5CcNNuhl5i0 (9 lines)
12:55 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/avr/atmega328/PCINT0/quadrature/
12:56 PM Tom_L: similar to andy's lookup
12:56 PM Tom_L: pure avr c not ardweenie
12:58 PM lcnc-relay: <meisterdippel@> robots, encoder, fpga, what ?
12:59 PM lcnc-relay: <andypugh@> Mine also needs this to set up the pins and interrupts:
12:59 PM lcnc-relay: "#define E1P1 26 #define E1P2 27"
12:59 PM lcnc-relay: ...
12:59 PM lcnc-relay: " pinMode(E1P1, INPUT_PULLUP); pinMode(E1P2, INPUT_PULLUP);"
12:59 PM lcnc-relay: ... long message truncated: https://jauriarts.org/_heisenbridge/media/jauriarts.org/KeVrjiGyAAvTZRyNpZZSwCFp/wR8eoYSCEx8 (6 lines)
12:59 PM Tom_L: i may have done one in asm too but forgot where i put it
01:00 PM lcnc-relay: <voiditswarranty@> Tom_L: heh yeah I HATE pulling in half the internet's dependencies just to use some simple algorithm someone posted on an arduino forum. Arduino was great for bringing mcu's to the masses, but sure made a mess of finding library agnostic examples of a hardware concept
01:07 PM rdtsc-w: 74HC74D - "C" means CMOS, so is static-sensitive, and any unused inputs need to be pulled to a rail.
01:12 PM lcnc-relay: <voiditswarranty@> https://github.com/digiexchris/SDEC
01:12 PM lcnc-relay: Here's something I forgot I had and didn't fully finish! C++ STM32F1 quadrature encoder using the hardware QDEC, I was going to make it output over SPI but hadn't gotten to it. tested to 1.5 million counts per second but in theory should be able to do 9 million. I should finish that SPI interface off and write a linuxcnc module for it. Looks like I might have been converting it to the rp2040 PIO too.
01:23 PM Unterhausen: is there a lcnc deb for rtai?
01:27 PM lcnc-relay: <voiditswarranty@> * STM32F4
01:29 PM lcnc-relay: <andypugh@> unterhausen@ Yes
01:30 PM lcnc-relay: <andypugh@> http://www.linuxcnc.org/dists/bookworm/base/binary-amd64/ - linux_image and rtai_modules
01:33 PM jdh: I want a piece of hardware I can put between an encoder and an older device
01:35 PM lcnc-relay: <voiditswarranty@> hmm there were a few QDEC chips around that could do that, but they're pretty rare these days. Probably less costly to buy a configurable magnetic encoder
01:35 PM jdh: The current encoder (made in 1986) puts out a pulse on one wire when going CW, another wire for CCW. Could also take step/dir.
01:36 PM jdh: Hard to find native 750 encoders.
01:36 PM lcnc-relay: <skunkworks8841@> oh - that is up/down..
01:36 PM jdh: Yeah
01:36 PM lcnc-relay: <skunkworks8841@> some steppers took that.
01:36 PM jdh: Yeah, In 1986
01:36 PM lcnc-relay: <voiditswarranty@> I've got a bfand new servo that could be setup that way, I was wondering about that
01:36 PM jdh: Actually many still do.
01:36 PM lcnc-relay: <voiditswarranty@> * brand
01:36 PM lcnc-relay: <andypugh@> I think you can do it with simple logic gates. One way is A AND B. The other is <something else> 🙂
01:37 PM lcnc-relay: <skunkworks8841@> lol - starts drawing a logic table...
01:37 PM lcnc-relay: <voiditswarranty@> maybe 4 logic gates?
01:38 PM lcnc-relay: <voiditswarranty@> debouncing that might be interesting!
01:38 PM lcnc-relay: <andypugh@> Might be a latch, rather than simple AND (I haven't got as far as finding a pencil yet)
01:39 PM jdh: Should be easy enough but I want to buy something
01:39 PM lcnc-relay: <voiditswarranty@> and then there's the pencil sharpening problem, and then we're back to the building a steam plant to power a robotic pencil sharpener problem from yesterday
01:40 PM jdh: It would also take a normal quadrature encoder signal, but I need 750 ppr
01:40 PM lcnc-relay: <andypugh@> I think you just output B on one channel and not-B on the other on each rising edge of A?
01:43 PM lcnc-relay: <voiditswarranty@> do you need 750 ppr regardless of whether it could take quadrature or up/down?
01:43 PM jdh: I was hoping to just use A or A/ from a 3000 count quad since it only rotates one direction but it seems to have a lot of edge problems
01:43 PM lcnc-relay: <skunkworks8841@> cui encoders don't do 750 - they only do 768
01:43 PM lcnc-relay: <voiditswarranty@> or 720, can buy 720 all day from mouser
01:44 PM jdh: Normal quad is 4x line count
01:44 PM jdh: Yes,so. Eo
01:44 PM lcnc-relay: <voiditswarranty@> take a 3000 CPR and do a 4:1 belt reducer
01:45 PM jdh: Poor choice was made in the 80's
01:45 PM lcnc-relay: <voiditswarranty@> * reducer. If it doesn't need a Z signal it doesn't matter how many turns the encoder does if the thing the encoder is attached to is counting the right number of counts per it turning
01:46 PM jdh: That might be OK. There are some encoder dividers also that would get the right count. But cw/CCW would be plug and play
01:46 PM lcnc-relay: <voiditswarranty@> but only if it's the same counts, right?
01:47 PM lcnc-relay: <voiditswarranty@> if it goes up 750 times, that's 1 spindle (or whatever) revolution?
01:47 PM jdh: Yep
01:47 PM lcnc-relay: <voiditswarranty@> I'm clearly missing something
01:47 PM jdh: Trigger on position for high speed digitizer
01:51 PM jdh: Current one is belt driven anyway so new pulley might be OK for a 3000ppr. Not so well documented wiring though.
01:56 PM lcnc-relay: <voiditswarranty@> mouser's got a bunch that can output a/b (quadrature), or step/dir, or other things too. Might be something close wiring wise. https://www.mouser.ca/c/electromechanical/encoders/
01:56 PM lcnc-relay: <voiditswarranty@> is the old one toast? they're not that complicated inside assuming the disc is intact, might be repairable
01:57 PM lcnc-relay: <voiditswarranty@> +with steady hands
02:05 PM Tom_L: andypugh_, is that rtai link memleak's latest RTAI build?
02:06 PM andypugh_: I am not sure. I think that it’s probably one I built.
02:07 PM jdh: Old one is fine. Nobody knows how the system works except me. I'm going to retire this summer. Wanted to make it more replacement friendly
02:07 PM Tom_L: https://onelaboratories.us/abc/
02:07 PM Tom_L: it would be nice if 2.9.3 was built against that rtai
02:09 PM Tom_L: Unterhausen, if you want the latest RTAI ^^ that's it
02:09 PM Tom_L: you need all 4 files
02:10 PM lcnc-relay: <voiditswarranty@> jdh: that's a good problem to have, congrats!
02:30 PM lcnc-relay: <skunkworks8841@> lol - I built a new zfs pool on a new external e-sata box. (purchased recently) well I think the box sucks. I came in this morning and 2 of the drives had dropped out and it was finding cksum errors. I fixed one of my older external drive bays (powersupply died) and rebooted the system with the drives in the old box. It is currently re-silvering - all the drives are up. It has currelty found 4 files with permanent...
02:30 PM lcnc-relay: ... errors. (it is 12% done of 10.5T)
02:30 PM lcnc-relay: <skunkworks8841@> first time I have seen this - kinda fun to play with stuff when it isn't important...
02:32 PM lcnc-relay: <skunkworks8841@> 2 are from a time and attendence program we haven't used in 20 years.. one is a 'windows XP Mode.vhd'
02:33 PM lcnc-relay: <skunkworks8841@> (it is running raidz2 - so it could lose 2 drives - but I think the new box was inserting a lot of errors)
03:05 PM lcnc-relay: <andypugh@> Tom_L: http://www.linuxcnc.org/dists/bookworm/2.9-rt/binary-amd64/
03:06 PM lcnc-relay: <andypugh@> (2.9.3_rt packages. Lovingly hand-built by myself as part of the release process. Partly why releases are infrequent, it's a fair bit of work)
03:06 PM roycroft: but do you also lovingly cover it with lark's vomit?
03:09 PM Tom_L: andypugh_, what RTAI is that built against?
03:10 PM lcnc-relay: <andypugh@> The one in the other debs
03:10 PM Tom_L: wondering if it would work on the 5.4.279 build
03:10 PM lcnc-relay: <andypugh@> You know, you could just read the docs.
03:11 PM lcnc-relay: <andypugh@> http://linuxcnc.org/docs/stable/html/getting-started/getting-linuxcnc.html#cha:Installing-RTAI
03:13 PM Tom_L: there is a newer kernel than described there
03:13 PM Tom_L: and those docs don't apply to that
03:14 PM Tom_L: not knowing what changes are required to make the two mesh i hesitate to install any of those debs
03:20 PM Tom_L: i've been running the newer kernel a while but it was built with 2.9.2
04:34 PM Unterhaus__ is now known as Unterhausen
04:35 PM lcnc-relay: <thorhian@> You linked to something that eats up to 1200W. That would leave around 5amps left on the circuit before tripping. I guess I could consider 1KW.
04:37 PM Tom_itx: i'm running my mill on one 20A? circuit and have had no problems
04:38 PM Tom_itx: they have smaller ones
04:38 PM Tom_itx: don't see where it shows the input voltage
04:39 PM CloudEvil: A power limited VFD can run a higher power spindle at a lower power, with various advantages.
04:45 PM roycroft: if you're running a 3 phase motor off a vfd with single phase input, remember to size the vfd 50% greater than your desired output power
04:45 PM roycroft: so get a 1.5hp or 2hp vfd to run a 1hp motor
04:50 PM lcnc-relay: <thorhian@> Yes, I’m aware.
06:12 PM lcnc-relay: <schoch_@> andypugh@ thanks for the link.
06:13 PM lcnc-relay: <schoch_@> voiditswarranty@ i have a gt3 hob half made made from a2, waiting for me to finish my heat treating oven project.
06:13 PM lcnc-relay: <schoch_@> I tested the process to make one with mild steel for GT2 and it worked well.
06:14 PM lcnc-relay: <schoch_@> cutting plastic to test fit fit well.
06:14 PM lcnc-relay: <schoch_@> I cut the lathe tool profile on my cnc mill.
06:16 PM lcnc-relay: <schoch_@> I strongly believe that making a webUI with websockets to do the data entry for something like that hob interface is much easier to live with (easier to develop/update/change)
06:16 PM lcnc-relay: <schoch_@> arduinoJSON is very usable and fast with an esp32, even better if you use msgpack
06:17 PM lcnc-relay: <schoch_@> if you need super fast data updates to the UI SSE is the way to go.
06:18 PM lcnc-relay: <schoch_@> I'll be digging into how well ESP32 -> ESP_NOW -> USB NCM ethernet -> UDP works, i need to test throughput's effect on latency and max updates/s
06:19 PM lcnc-relay: <schoch_@> Right now i'm polling my encoder around 50ms and it is very snappy for LCNC MPG joggin.
06:20 PM lcnc-relay: <schoch_@> the best solution i to live with the wire and just hook everything up to RIO, but i'm a glutton for punishment and have many many more wires than I want to live with.
07:25 PM memleak: Tom_L, you're interested in 5.4.279 rtai?
07:26 PM memleak: the kernel debs here are ones i built, capthindsight built the linuxcnc deb: https://onelaboratories.us/abc/
07:32 PM memleak: firephoto_, i'm on ryzen too!
07:37 PM roycroft: well, my seal installation tool finally arrived
07:37 PM roycroft: it took at least as long, if not longer, to bring it into the shop and unbox it as it took to install the seal
07:37 PM roycroft: but that's ok, and now i have the tool in case i have to do the other side
07:38 PM xxcoder: lol. well thats nice
07:39 PM rdtsc: schoch, 'have a gt3 hob half made made from a2, waiting for me to finish my heat treating oven project' - sounds a lot like https://www.youtube.com/watch?v=ByyT5XvQSag
07:39 PM rdtsc: excited roycroft? will be driving it again soon :)
07:44 PM roycroft: i hope so
07:44 PM roycroft: i need to finish moving before the thieves finish moving for me
07:45 PM xxcoder: yeah you dont want to offer 5 finger discount
07:45 PM roycroft: almost everything that i care about that's left in that shop is pretty heavy - my 7x12 bandsaw is the lightest thing there that i care about - so it's unlikely they'll haul that stuff off
07:46 PM roycroft: it would be hard, because the ground is really soft and the stuff is pretty far awy from the driveway and street
07:46 PM roycroft: a 4wd vehicle would be required to get close enough to the building to load that stuff
07:46 PM roycroft: or waiting until may or june
07:47 PM Tom_L: memleak, i'm using those currently
07:47 PM roycroft: it's dark now, and i'm not going to work on the truck in the dark, but getting that seal installed is a major step forward - that was the roadblock keeping me from finishing it up
07:47 PM roycroft: so hopefully saturday i'll be able to drive it again
07:47 PM memleak: ah ok!
07:47 PM Tom_L: just would like to have 2.9.3
07:48 PM memleak: i'll update that soon
07:48 PM xxcoder: next week looks like will be sunny and very cold nights
07:48 PM xxcoder: 30-32f
07:48 PM Tom_L: that's what all the fuss was about
07:48 PM Tom_L: none of the mainstream builds would work on it would they?
07:48 PM roycroft: it was clear and cool here today
07:48 PM roycroft: but when i got down towards the valley it was cold with pea soup fog
07:49 PM roycroft: and yeah, we might get down to freezing this weekend
07:49 PM memleak: the linuxcnc debs need to be built against the same kernel, you can't mix and match debs
07:49 PM roycroft: looks like a bit of rain tomorrow, then dry for the next week
07:49 PM Tom_L: that's what i thought
07:49 PM memleak: you'd be able to build linuxcnc debs faster than i could at the moment
07:49 PM Tom_L: andy scolded me for not reading the docs...
07:50 PM Tom_L: but i'd already been there
07:50 PM memleak: easy as ./debian/configure ; dpkg-buildpackage -uc -us
07:50 PM Tom_L: i'm not in a hurry
07:50 PM lcnc-relay: <skunkworks8841@> andy is the new JMK? 😉
07:50 PM memleak: i dont have debian at the moment
07:50 PM Tom_L: checkout 2.9 from source then run that?
07:50 PM Tom_L: on the RTAI pc right?
07:51 PM memleak: yep!
07:51 PM Tom_L: does ./debian/configure take any arguments?
07:51 PM memleak: lemme check
07:52 PM Tom_L: i was trying to remember what the no docs switch was too but can't find my notes
07:52 PM memleak: the nodocs thing is completely broken atm
07:52 PM memleak: i forked the linuxcnc repo to pull doc building out
07:53 PM Tom_L: i use the mainstream source right?
07:53 PM memleak: yes and you should have docs
07:53 PM Tom_L: why? i don't read em anyway
07:53 PM lcnc-relay: <skunkworks8841@> lol
07:53 PM memleak: i ripped it out of my tree so CaptHindsight could build debs without waiting an hour for it to build
07:53 PM lcnc-relay: <skunkworks8841@> docs are usually the last resort..
07:53 PM Tom_L: exactly
07:54 PM memleak: otherwise docs are always built
07:54 PM Tom_L: no big deal
07:54 PM memleak: you could cherry-pick my commits though if you want
07:54 PM xxcoder: surpised that theres no "no docs" option to build
07:54 PM Tom_L: takes about 1/3 the time without
07:54 PM Tom_L: i'm not going to that trouble
07:54 PM Tom_L: xxcoder, there is
07:54 PM xxcoder: ahh ok
07:55 PM memleak: this is the commit to build linuxcnc debs without docs: https://github.com/NTULINUX/linuxcnc/commit/a197dad865a02e47a2aee4038eb1fb8089423d70
07:56 PM memleak: otherwise you just have to wait forever :)
07:56 PM Tom_L: you say the docs switch is broke?
07:58 PM Tom_L: bak in a bit
08:24 PM Tom_L: guess i'll try it and see
08:24 PM Tom_L: worst is i'll have to reinstall the ones from capn's site
08:29 PM Tom_L: --enable-build-documentation=no
08:31 PM Tom_L: doesn't work :)
08:43 PM Tom_L: seems to be building something...
08:51 PM Tom_L: errpr
08:51 PM Tom_L: error'd out
09:08 PM rifraf: hi, does it seem normal to have to supply digital i/o inputs on servo controller with a 24V dc external source to drive the input optos?
09:09 PM Tom_L: field voltage?
09:09 PM rifraf: Am about to try as just the signal and ground is never triggering the input and feel I may have already killed the inputs, is a T3D L20A
09:10 PM rifraf: the outputs from cnc controller ar measuring ~2.2V when high, 0V low
09:11 PM rifraf: hi Tom_L the servo driver input is run direct from 240V, you would think it can power the i/o inputs but may be isolated so the optos have no power coming from the drive itself
09:11 PM Tom_L: i don't know alot about those
09:11 PM Tom_L: but alot of times you need to supply power to the optos
09:11 PM Tom_L: be it sinc or soruce
09:12 PM rifraf: my first time with real servo drives, if I can get the inputs working can do some cool stuff, I need to be able to control in position mode like a stepper and on the fly change to speed control mode because cannot drive it fast enough with dir/pulse inputs
09:13 PM Tom_L: i'm still using steppers
09:14 PM Tom_L: what you been up to?
09:14 PM rifraf: the difference is amazing Tom, can drive it 3 times faster, 10 times quieter and much more torque, has changed the machine entirely
09:15 PM rifraf: been upto making this CNC still and lots of smaller projects that have recently been completed
09:15 PM rifraf: i'll just show you this connection diagram, clearly seems to imply i need 24v
09:17 PM rifraf: page 2 diagram shows the DI inputs 1 to 6 https://cnc-tehnologi.ru/files/t3d_servo_ENpdf.pdf
09:17 PM Tom_L: hah i just had that open
09:17 PM rifraf: well only show 4 on there
09:18 PM rifraf: the only guy with good info for this unit is russian, so am loosing a bit of info in translation
09:18 PM Tom_L: i ran some chinese ones thru google translate...
09:18 PM Tom_L: did a fair job
09:19 PM rifraf: surely I cannot kill it by giving it 24v when it is asking for it
09:19 PM Tom_L: 24v is pretty common
09:19 PM rifraf: these are youtubes only, so its doing the translation, is great but did not see him mention the 24V
09:20 PM rifraf: ok, am gonna do it, will report back soon, hopefully can keep the magic smoke inside, i love this new motor/driver
09:21 PM Tom_L: well you're far enough away i won't see the smoke
09:22 PM Tom_L: rifraf, look on P11 (P20)
09:22 PM rifraf: i used the old stepper and rebiult the tailstock, is now way fast as well, more torque and can drill hole 150mm deep pretty fast
09:23 PM Tom_L: from 11 fwd
09:24 PM rifraf: yep i have been in this manual for a week now, I am either soo close or have damaged the inputs, but if the optos need power then they should still be ok because never been powered up
09:24 PM Tom_L: wait i have another one open
09:24 PM Tom_L: https://www.hlt-cnc.com/uploads/38006/files/T3D-Full-manual-V2.3_-English-version.pdf
09:25 PM rifraf: yep i have about 5 versions downloaded plus the printed copy, they all have different amounts of detail on different parts
09:25 PM rifraf: gonna go hook up a 24v source and test now
09:26 PM Tom_L: the one you linked looks like it's for programming the drive
09:26 PM Tom_L: features
09:30 PM rifraf: and there is a bit of programming/slash configuring to do to acheive what i am aiming for, but this morning before work did a factory reset on driver, but won't take long to get basics going again
09:30 PM Tom_L: External voltage range DC12V to 24V.
09:30 PM Tom_L: for the digital inputs
09:31 PM rifraf: yep I am going with 24 cause had that available in the control box, the controller itself only has 5V outputs, thats why I was wary of the 24v
09:31 PM Tom_L: it also shows a diagaram using 5-24v
09:31 PM Tom_L: on the optos
09:31 PM Tom_L: on 12
09:33 PM rifraf: for the pulse inputs, like stepper control
09:33 PM rifraf: that part is working fine using the 5v inputs
09:33 PM Tom_L: ok
09:33 PM rifraf: again I have not seen stepper drivers that output a 24v signal
09:35 PM Tom_L: what software are you driving the cnc with?
09:35 PM rifraf: i think this could be a great controller, will reserve judgement till i get these wires soldered up and test, but have want this feature since i made the machine, have been getting by with external switches
09:35 PM rifraf: notepad
09:35 PM Tom_L: control software
09:35 PM rifraf: the controller is an SMC5-5 standalone controller,
09:36 PM Tom_L: hmm
09:36 PM rifraf: another chinglish manual but have used it for nearly a year now and is pretty robust
09:36 PM rifraf: https://www.lollette.com/support/pdf/CNC/SMC5-5.pdf
09:37 PM Tom_L: have a look at linuxcnc sometime
09:38 PM rifraf: yep i have, need to update it again though, i figured you guys need to do the same things to control servos
09:39 PM rifraf: but i keep getting distracted, back soon
09:59 PM rifraf: so freaking cool :) can change i/o, now to set up the settings again, used 12V and it was enough
10:00 PM rifraf: this is a super leap forward for this machine, no more flicking manual switches (which really sucked when you forgot to) and using other stepper controllers etc.
10:01 PM Tom_L: cool
10:02 PM rifraf: look at one of these for a second spindle or rotary axis like i have maybe, the $$ not bad for what you get, what sizes steppers you have now?
10:04 PM rifraf: Tom_L did you try making any spinning tops?
10:04 PM Tom_L: no
10:04 PM Tom_L: https://www.ebay.com/itm/253223632606
10:05 PM Tom_L: steppers i have
10:05 PM rifraf: omg! sooo happy right now, have been on this all week when not working
10:05 PM Tom_L: 1.2kw spindle upgrade recently
10:06 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/Mill_Steel/Assembly/Final/chip_guards/Chip_guard5.jpg
10:06 PM rifraf: decent price and about the same size i have on 3 axis, but am using the closed loop with inbuilt driver for a couple now, soo nice compared to separate driver
10:07 PM Tom_L: iirc i gave $99 for the set
10:07 PM rifraf: cool, only have a 500w spindle on this , but was about to cut a perfect 5mm wide 200mm long keyway in 4140
10:07 PM Tom_L: you'd better say hi to rue :)
10:21 PM roycroft: are you about, xxcoder?
10:21 PM xxcoder: yep
10:22 PM xxcoder: whats up?
10:22 PM roycroft: that little cnc router you gave me - you said that the stepper motors were underpowered
10:22 PM roycroft: was that all three motors, or just the x-y motors?
10:23 PM xxcoder: not sure on z, dont think I ever saw it stall
10:23 PM roycroft: ok
10:23 PM roycroft: i'm starting to figure out what i need to do to make it work
10:23 PM xxcoder: cool :)
10:24 PM xxcoder: of course its always possible that I didn't configure linuxcnc correctly
10:24 PM roycroft: perhaps i should just get it working with the current motors and see how it goes
10:24 PM xxcoder: easy enough tp swap steppers yeah
10:24 PM roycroft: i really wish it had a faster spindle, but i see it's hard to find faster spindles that small for some odd reason
10:25 PM roycroft: but i'll figure out how to make what's there work
