02:02 AM Deejay: moin
02:27 AM t4nk_freenode: good morning, Sirs
02:32 AM travis_farmer853: G'Morning ☕
03:56 AM t4nk_freenode: if I had a time-machine... I'd go back in time..
03:56 AM t4nk_freenode: and kill...
03:56 AM XXCoder: me?
03:56 AM t4nk_freenode: the one responsible for plain screws.
03:56 AM XXCoder: slot type? it was easy to machine
03:57 AM t4nk_freenode: yeah, it wasn't a really bad idea either hehe
03:57 AM XXCoder: what id do is teach them how to broach lol
04:01 AM CloudEvil: I'd assumed commercial screws are hot formed.
04:02 AM XXCoder: very cheap ones maybe?
04:02 AM XXCoder: most is made by lathe turrets I'd say
04:02 AM XXCoder: one guy probably can run 10 turrets and only ened to fix something once a while.
04:03 AM CloudEvil: (the part accepting the driver)
04:07 AM t4nk_freenode: mmmzz, they used wooden screws BC. to press olives
04:08 AM t4nk_freenode: but handheld drivers only from medieval times
04:10 AM t4nk_freenode: mmmmm I may have to whack a whole bunch of people ...
04:10 AM * t4nk_freenode nevertheless starts a list
04:42 AM Tom_L: morning
05:16 AM JT-Cave: morning
05:16 AM Tom_L: i sent you a script to speed up making pin files
05:16 AM JT-Cave: I was just reading that
05:18 AM Tom_L: took a bit for me, i don't do scripts much
05:19 AM Tom_L: change the rights to execute :)
05:20 AM Tom_L: i did notice some zips have a few in them
05:20 AM Tom_L: but not all
05:25 AM JT-Cave: I think I'll make a python program to load all bit files then if no pin file create one
05:37 AM JT-Cave: just pushed the fix for 7i80 mesaflash stuff
07:15 AM Tom_L: no 7I80HD_16 board found
07:19 AM unterhaus: is 1cm of rain a lot? Trying to decide if I should plant some seedlings in my garden or wait after the rain
07:21 AM Loetmichel: its one liter per square meter
07:21 AM Loetmichel: not thaaat much
07:34 AM JT-Cave: did you get a fresh copy of the deb and reinstall it?
07:35 AM JT-Cave: https://imagebin.ca/v/6j9ZeDNHWTgQ
07:37 AM JT-Cave: looks like I created an error changing _ to -...
07:40 AM JT-Cave: yuck a catch 22 error, fix one another breaks
07:56 AM JT-Cave: fixed that
07:56 AM JT-Cave: time to start my chicken day
09:06 AM -!- #linuxcnc mode set to +v by ChanServ
10:02 AM -!- #linuxcnc mode set to +v by ChanServ
10:46 AM roycroft: shars offered me a $20 refund to keep that square instead of sending me a new one
10:46 AM roycroft: $20 is exactly what i was thinking would be a resonable discount
11:02 AM CloudEvil: Yay?
11:02 AM CloudEvil: I mean, fair enough on the quality if it was from aliexpress.
11:02 AM CloudEvil: But...
11:04 AM roycroft: it was from shars
11:04 AM roycroft: which should be a step above aliexpress
12:19 PM rmu: unterhaus: 1cm of rain is 10 liters per square meter.
12:20 PM rmu: there are 1000mm to the meter and also 1000 liter to one meter cubed
12:32 PM unterhaus: 10 liters per square meter seems like a lot. Oh well, hopefully the kale and tomatoes survive it
12:43 PM Tom_L: JT-Shop, yes i did a fresh install from the utility
12:47 PM CaptHindsight[m]: we measure rainfall in inches, so it's 2.54 times worse
12:47 PM Tom_L: buckets
12:49 PM Rab: pcw-home, hi! I went to order a 7I77-6I25 PNG kit yesterday but it was out of stock. Both 6I25 and 7I77 show in stock separately. Is the kit just a detail for the online store or is there something actually OOS?
12:51 PM Rab: Let me know if I should call or email directly, I don't know if you or this channel are appropriate targets for sales questions.
12:51 PM Tom_L: as long as we get a cut
01:01 PM pcw-home: Just a detail in the store, fixed
01:02 PM Rab: pcw-home, great, thanks!
01:07 PM Rab: Tom_L, lemme know where to send the dogecoin
01:09 PM roycroft: you mean the tens of thousands of dogecoins :)
01:10 PM serp: Anyone know where to get a thcad-10 that has it in stock? :)
01:11 PM Connor: Hey everyone. My Maker Space just received a CNC Plasma as a donation. Looks to be running old Flash Cut brain box. The stepper driver box looks to be from Practical CNC, along with a AVC-2, which I think is a torch height control unit? Anyone know anything about those.. I can't find any info on it.
01:11 PM Tom_L: serp, nope.. jt and pcw are the only ones i know of
01:13 PM Rab: I have a FleshCut setup...the software came on three 3.5" floppies.
01:13 PM Tom_L: sounds painful
01:14 PM Tom_L: ooo i have one of those from my sherline
01:14 PM Rab: It is. I have to post-process my gcode back to 199x before it accepts it.
01:14 PM Tom_L: rs232 :)
01:15 PM Connor: Yea, the plan is to ditch all of that and go with more modern steppers & drivers, use the MESA, and as @serp was asking, maybe switch to the thcad-10 if the AVC-2 isn't practical or of benefit.
01:16 PM Rab: Tom_L, yes, my friends and I tried to sniff the controller protocol, but it appears to be sending raw timing information by jiggling the signal lines rather than sending serial ASCII.
01:16 PM Tom_L: mine's tucked away on a shelf somewhere
01:17 PM Rab: Connor, this box? Not part of my setup, sorry. https://www.ebay.com/itm/164885436308
01:17 PM Connor: Rab: Yup. That's the one.
01:19 PM pcw-home: serp: some in the store now
01:20 PM Rab: Connor, Plasma Technologies appears to still be around, have you tried contacting them directly? https://plasmatechnologies.com/
01:21 PM * Tom_L thinks pcw-home has a secret board stash
01:21 PM Connor: Is Practical CNC the same as Plasma Technologies?
01:22 PM Connor: I thought the company was Practical CNC
01:22 PM Rab: I just went by the eBay listing: https://i.ebayimg.com/images/g/ipwAAOSw~CNgrsHl/s-l1600.jpg
01:22 PM pcw-home: we have a few of some things, but when we are out it'a going to be a long gap before we have stock again
01:23 PM pcw-home: shipments of special parts like digital isolators with power are more than a year out
01:24 PM XXCoder: working on alternate designs to get around supply blockages?
01:24 PM Tom_L: wow
01:24 PM ZincBoy[CAON]066: At work we have been getting 52week leadtimes and some CPLDs that were $1 are selling for $300 on the secondary market.
01:24 PM pcw-home: you can until the next part goes up to 45 week delivery
01:25 PM CaptHindsight[m]: people have been buying finished products and de-soldering parts for reuse in their own products
01:25 PM serp: pcw-home: i thought i checked... which site is yours? mesa?
01:26 PM pcw-home: Even the Efinix Chips are disappearing
01:26 PM Tom_L: pretty soon they'll be designing around vacuum tubes again
01:26 PM CaptHindsight[m]: best bet might be getting a space suit and flying to shenzhen
01:26 PM CaptHindsight[m]: and hope you can leave
01:27 PM roycroft: actually there is a vacuum tube shortage right now
01:27 PM roycroft: since the war started, as most vacuum tubes were made in russia
01:27 PM Tom_L: there was a guy there that would get stuff for us but i don't think he's there now
01:27 PM pcw-home: Ive made some 0.25"x0.25" SO8 adapters PCBs to allow using available power supply chips on existing PCBs
01:27 PM CaptHindsight[m]: GE or similar just reopened a tube facility
01:27 PM roycroft: it wasn't ge, but a small outfit
01:28 PM roycroft: iirc they were making small quantities of high end tubes for audio amps
01:28 PM roycroft: and they just expanded to be able to service the musician market as well
01:29 PM roycroft: i've said this here, before
01:29 PM CaptHindsight[m]: https://guitar.com/features/interviews/exclusive-western-electric-confirms-plans-tube-georgia-factory-crisis/
01:30 PM roycroft: there is nothing good about wars, but this war is actually helpful in that it's prodding us to start moving manufacturing back to the us
01:30 PM CaptHindsight[m]: nah
01:30 PM CaptHindsight[m]: we haven't tried all the wrong choices yet
01:31 PM roycroft: we're starting to run out of wrong choices
01:31 PM roycroft: and more importantly, we're starting to actually recognise that we're making wrong choices
01:31 PM roycroft: at least some of us are
01:31 PM roycroft: that article pretty much says what i said
01:31 PM CaptHindsight[m]: and in words
01:32 PM roycroft: i said it in words
01:32 PM roycroft: but that article also has pictures
01:33 PM roycroft: so that young whippersnappers can get an idea of what a 'vacuum tube' is
01:33 PM CaptHindsight[m]: if the type isn't big enough then you have to add pics
01:33 PM roycroft: i was watching a youtube video the other day about the repair of an old 1970s time clock
01:34 PM roycroft: the presenter kept referring to the "ink tape"
01:34 PM roycroft: i kept yelling "RIBBON"
01:34 PM roycroft: yet he kept saying "ink tape"
01:34 PM CaptHindsight[m]: pcw-home: ever try your VHD files in Vivado, there was some import warning (I forget which, maybe format)
01:34 PM CaptHindsight[m]: I haven't built with them yet
01:35 PM coralgoat: I have three Micro Stepper NEMA 34 motors.
01:35 PM coralgoat: I am looking for stepper motor drivers for these motors.
01:35 PM * roycroft wonders how loudly one must actually shout for youtubers to hear
01:36 PM coralgoat: What specs should I be looking at for the stepper motor drivers so that they will work with nema 34 micro stepper motors?
01:36 PM CaptHindsight[m]: roycroft: depends on their volume setting I suppose
01:37 PM CaptHindsight[m]: coralgoat: what type of windings and do you have any voltage or current specs?
01:37 PM pcw-home: I haven't bothered with Vivado, And I probably wont mess with it since I cannot get any Xilinx chips for at least a year
01:37 PM roycroft: get you some gecko drives and you'll be fine :)
01:37 PM Rab: coralgoat, do you have a link to the product?
01:38 PM CaptHindsight[m]: coralgoat: https://en.wikipedia.org/wiki/Stepper_motor#Two-phase_stepper_motors
01:38 PM roycroft: geckos are probably too small for some of the bigger nema 34 steppers
01:38 PM Tom_L: 7A
01:39 PM Tom_L: 80v
01:39 PM roycroft: thanks
01:39 PM coralgoat: CaptHindsight[m], the stepper motor drivers I am trying to replace are Yako YKC2405M.
01:39 PM Tom_L: 203v iirc
01:39 PM coralgoat: Here is a link for them that I have found.
01:40 PM coralgoat: https://www.alibaba.com/product-detail/Original-YAKO-brand-Stepper-Motor-Driver_60417748832.html
01:40 PM roycroft: i knew geckos handle 80v, but i'd forgotten the max current
01:41 PM coralgoat: I am trying to get a CNC router that runs on one 240V to work with multiple 120V outlets instead.
01:41 PM pcw-home: that looks like Gecko G540, G251 territory (3A 50V)
01:42 PM coralgoat: Currently it has a box that handles everything with one 240V plug.
01:43 PM Rab: coralgoat, that's usually the hard way. I guess there's no chance of finding a 240V circuit?
01:44 PM CaptHindsight[m]: pcw-home: was going to use some of your VHD with ZYNQ
01:44 PM ZincBoy[CAON]066: Step up transformer is probably the easiest option if 240V is not an option
01:46 PM coralgoat: I am planning to split out the components stepper motor drivers to use a 120V outlet and the spindle VFD another 120V outlet.
01:47 PM ZincBoy[CAON]066: The steppers probably could run off 120 but the spindle will not if it is designed for 240.
01:47 PM CaptHindsight[m]: https://www.forum.linuxcnc.org/27-driver-boards/44422-colorcnc-colorlight-5a-75e-5a-75b-as-fpga-controller-board?start=150#244201 this project is coming along using Lattice FPGA's
01:48 PM coralgoat: ZincBoy[CAON]066, the spindle is 2.2 kW, 3 HP, 24000 RPM
01:49 PM ZincBoy[CAON]066: Ya, you aren't running that off a 120V outlet. You will need both 240V and more current than a standard 120 outlet can provide.
01:49 PM coralgoat: CaptHindsight[m], I do not know the type of windings, voltage or current specs.
01:51 PM CaptHindsight[m]: coralgoat: but you are saying that the stepper drives you linked to did work with the nema34 motors you are asking about?
01:51 PM coralgoat: The motors are hidden away inside the router so I am not sure how much information I will be able to get off of them. But I will see what I can get.
01:51 PM pcw-home: unfortunately Lattice is as bad or worse than Xilinx delivery wise
01:52 PM coralgoat: CaptHindsight[m], yes the the stepper drives I linked to did work with the nema 34 motors I am asking about.
01:52 PM CaptHindsight[m]: pcw-home: yeah but those complete boards are ~$16ea
01:53 PM CaptHindsight[m]: maybe a stockpile in China
01:53 PM CaptHindsight[m]: coralgoat: ok, then that is good enough
01:53 PM CaptHindsight[m]: no need to tear apart the router
01:55 PM Tom_L: JT-Shop, readhmid works ok now
01:55 PM coralgoat: pcw-home, I think I would prefer to have three stepper motor drivers so I can replace one if it fails. So this one <https://www.geckodrive.com/g251x-digital-stepper-drive.html>?
01:56 PM CaptHindsight[m]: https://www.pjrc.com/store/teensy41.html Inventory Status: Out Of Stock
01:56 PM CaptHindsight[m]: Last physical count: May 23, 2022
01:57 PM CaptHindsight[m]: https://www.led-card.com/colorlight-5a-75-ture-color-led-processor.html
01:57 PM coralgoat: Rab, I can ask about adding a 240V outlet not sure if that will be an option.
01:57 PM ZincBoy[CAON]066: coralgoat, are your current drives dead? Why are you replacing them?
01:57 PM CaptHindsight[m]: 121 in stock
01:58 PM Tom_L: i still have most of these: http://tom-itx.no-ip.biz:81/~webpage/boards/new_batch/USB_chips.jpg
01:58 PM Tom_L: maybe i should ebay them
01:59 PM Tom_L: well half a tray anyway
02:00 PM Rab: A friend of mine had a partial reel of ATmega32u4, he was just giving them away...we checked street price and the remainder of the reel was worth ~$6,500.
02:00 PM Tom_L: those are U2
02:01 PM coralgoat: ZincBoy[CAON]066, you said "Step up transformer is probably the easiest option if 240V is not an option". Do you mean a step up transformer from 120V to 240V?
02:02 PM ZincBoy[CAON]066: Yes. It does mean that you need 2x the current though.
02:04 PM ZincBoy[CAON]066: So if the router needed 20A at 240V, it would require 40A at 120V. It is probably cheaper to just run a 240 circuit unless you already have a high current 120V outlet.
02:06 PM Rab: coralgoat, is the router in a residential or a commercial setting?
02:11 PM coralgoat: ZincBoy[CAON]066, "are your current drives dead? Why are you replacing them?" The administrators wants to keep the existing controller box intact for manufacturer warrenty reasons. But it requires 240V and has a controller that is not compatible with Linuxcnc. But it looks like I will be able to replace that controller boxes components and that will be okay with the administrators.
02:13 PM coralgoat: recreating the box looks like it will get the go ahead
02:16 PM CaptHindsight[m]: coralgoat: great ides, i should try that on a new Haas, swap controllers, wait ten years replace with orginal controller , sell as new machine :)
02:17 PM ZincBoy[CAON]066: You will be able to get the axis drives running on 120V. Even the existing axis drives are powered by a supply that probably has a input voltage select. At worst case you need to replace the DC supply for the drives with one that will work at 120V. However, your spindle will not work on a 120V supply. It will need either a 240V supply or a step up transformer of sufficient size. This is due to the motor voltage requirements.
02:20 PM coralgoat: ZincBoy[CAON]066, what is a good way to identify a 40A at 120V outlet (circuit)?
02:21 PM XXCoder: dont that have special plugs
02:21 PM XXCoder: additional bar to one of "eyes"
02:23 PM ZincBoy[CAON]066: I don't think there is a 120-40 NEMA outlet. The closest would be a 5-30 or 5-50 at 30A and 50A
02:24 PM XXCoder: nema14 apparently yeah
02:24 PM XXCoder: https://www.wikiwand.com/en/NEMA_connector
02:24 PM ZincBoy[CAON]066: They will be bigger than a standard 5-15 as well
02:27 PM ZincBoy[CAON]066: NEMA14 would be 240V split phase and the discussion would be moot. NEMA5 is 120V as is NEMA1 but ungrounded.
02:30 PM coralgoat: Okay so here is a summary of my understanding of the options:
02:30 PM coralgoat: 1) put in a 240V outlet
02:32 PM coralgoat: 2) get a transformer (requires 120V 40A outlet)
02:33 PM coralgoat: I guess I could also downgrade the spindle motor to something that will work with a 120V VFD.
02:47 PM roycroft: 40a circuits are rather uncommon
02:48 PM roycroft: and i would not want to run a 120v circuit at more than 30a if i could help it
02:48 PM ZincBoy[CAON]066: 40A was just guess. It will depend on what your machine requires at 240V
02:48 PM coralgoat: okay
02:49 PM roycroft: the wiring and the connectors are just too hard to manage
02:49 PM roycroft: if i needed that much power i'd definitely move up to 240v
02:50 PM coralgoat: Would a transforer like this work:
02:51 PM coralgoat: https://www.amazon.com/dp/B089T2XK2K?th=1
02:52 PM coralgoat: to take the 120V to 240V?
02:52 PM travis_farmer853: not many watts...
02:53 PM -!- #linuxcnc mode set to +v by ChanServ
02:53 PM ZincBoy[CAON]066: Yes, but it needs to be at least 3kva and preferably 5kva.
02:53 PM roycroft: what are the specs of your spindle motor?
02:54 PM * roycroft missed the beginning of this
02:54 PM ZincBoy[CAON]066: 2.2kw/3hp
02:54 PM roycroft: oh, not a big deal
02:54 PM roycroft: you can do that with a 240v/20a circuit
02:54 PM roycroft: easily
02:55 PM ZincBoy[CAON]066: Yes, but the question was how to do it on a 120V cct.
02:55 PM roycroft: the answer is: pull a 240v circuit if at all possible :)
02:56 PM travis_farmer853: my thoughts too roycroft
02:56 PM roycroft: the 8ga wire to pull the 40a 120v circuit would cost a fortune
02:56 PM djdelorie: the inverter for my 2.2k spindle says it needs 22 amps at 240, so you'd need 44 amps at 120, which is a 50 amp circuit anyway
02:56 PM coralgoat: Okay I will try for 240V ciruit as the most prefered option.
02:56 PM roycroft: or 6ga, depending on the length of the pull
02:57 PM roycroft: 240v@20a is 4800w
02:58 PM roycroft: unless your inverter is horribly inefficient that spec is very conservative
02:58 PM djdelorie: likely
02:58 PM djdelorie: WJ200
02:58 PM roycroft: iirc those inverters need approximately 50% more power on input to convert to 3 phase
02:59 PM roycroft: so you really need roughly 3500w of single phase power to produce 2200w of 3 phase power
02:59 PM roycroft: my belt grinder has a 3hp motor on it
02:59 PM roycroft: its vfd runs on a 20a 240v circuit
03:00 PM ZincBoy[CAON]066: There is a big difference between the cct protection current and the actual current draw of the inverter. If a inverter was 50% efficient it would melt.
03:00 PM roycroft: and there's a 50' extension corde between the fabrication shop and the recepticle
03:01 PM roycroft: the extension cord has never even gotten a wee bit warm, even when i've been running the grinder under load for a prolonged period of time
03:01 PM roycroft: and the grinder does not seem at all sluggish, as though it did not have enough power
03:01 PM djdelorie: it calls for a 30A circuit for the 2.2kw inverter...
03:02 PM roycroft: is this a rotary phase converter or something?
03:02 PM djdelorie: It's a WJ200
03:02 PM * roycroft is not familiar with that
03:03 PM djdelorie: small Hitachi electronic box
03:03 PM ZincBoy[CAON]066: Hitachi drive
03:03 PM roycroft: oh, it looks like a vfd
03:04 PM roycroft: i'd call its power spec rather conservative
03:04 PM djdelorie: and it's capable of driving a 3.0KW motor in one of its modes, 2.2Kw in others
03:04 PM coralgoat: For the down grade option to get a spindle motor that works with 120V outlet what kind of specs should I be looking at for the spindle motor and VFD?
03:04 PM ZincBoy[CAON]066: 30A is the fuse size. It is sized to avoid blowing the fuse during power on inrush.
03:04 PM roycroft: that said, some motors create rather large current spikes when starting up, especially under load
03:04 PM djdelorie: 30A breaker, 40A fuse
03:05 PM roycroft: i would not get anything larger than a 2hp motor if i were going to run it on 120v
03:05 PM roycroft: and i'd probably get a 1.5hp motor
03:06 PM roycroft: i generally run any motor that's 1hp or larger on 240v, when possible
03:06 PM roycroft: but that's because i don't use many small motors
03:07 PM roycroft: and i'm set up with 20a 240v circuits/extension cords all over my shop
03:07 PM djdelorie: or start with the vfd you can get, or the circuit you can get, and find a motor/spindle that fits in that amp range
03:07 PM djdelorie: My shop is still mixed 120/240 but slowly switching to more 240
03:07 PM roycroft: i still have 120v, of course
03:07 PM djdelorie: I might need to bump my subpanel up too
03:08 PM roycroft: i only have one split phase circuit, btw - for my brew system
03:08 PM travis_farmer853: my 3ph 5hp spindle and el-crappo VFD runs on a 20A 240 circuit, over 10AWG wire... i think i am starting to understand why it gets up to speed so slow... 😦
03:09 PM roycroft: i generally don't see the point to having split phase circuits, but my brew system control panel, and the pumps, mostly run on 120vac or 12vdc
03:09 PM ZincBoy[CAON]066: I put in a 240 to 575V three phase stepup transformer so I can run all the cheap equipment. Also means the wiring is really cheap.
03:09 PM roycroft: my heating elements are all 240vac though
03:09 PM roycroft: so it made sense to me to bring a 50a split phase circuit to the control panel
03:09 PM -!- #linuxcnc mode set to +v by ChanServ
03:09 PM roycroft: yes, that's one of the big advantages of using higher voltage
03:09 PM roycroft: wiring is a lot cheaper
03:30 PM * CaptHindsight[m] runs everything at 121/209 to save amps
03:39 PM Tom_L: cloudy & 59F
03:40 PM XXCoder: cloudy and 64f
03:52 PM Tom_L: JT-Shop, what directory do you pull the pin files from?
04:13 PM roycroft: it's cloudy here, but about 22 degrees
04:24 PM CaptHindsight[m]: 73f and 53% humidity, partial clouds, lots of truck noise today
04:25 PM CaptHindsight[m]: lots of various midges but not stinging or biting bugs yet
04:25 PM CaptHindsight[m]: first warm day last month i was bitten several times by some invisible pests
04:26 PM CaptHindsight[m]: nothing since
04:27 PM travis_farmer853: 63F here, and 52% humidity... though for the scientificly minded, it is 290.4 degrees Kelvin 😉
04:31 PM JT-Shop: Tom_L, https://github.com/jethornton/mesact/tree/master/mesact/src/firmware
04:32 PM JT-Shop: hmm they reduced the chance of rain today and tomorrow
04:32 PM roycroft: the wiley mosquiteaux are out in force at the country fair
04:34 PM Tom_L: JT-Shop, i meant locally
04:34 PM Tom_L: to store the pin files
04:34 PM JT-Shop: https://github.com/jethornton/mesact/blob/master/mesact/debian/install
04:35 PM Tom_L: where does the utility look to find them?
04:36 PM JT-Shop: https://github.com/jethornton/mesact/blob/master/mesact/debian/install
04:36 PM JT-Shop: that's where everything gets installed
04:37 PM Tom_L: i guess i lost ya
04:37 PM Tom_L: it looks to your website to see if a pin file is there?
04:37 PM JT-Shop: I guess I'm not understanding what your are asking
04:38 PM JT-Shop: if you look at the link it is the debian install which has all the locations where files get installed
04:38 PM Tom_L: when it returns 'no pin file found for xxxxxx.bit
04:38 PM Tom_L: where is it looking?
04:38 PM JT-Shop: did you look at the github link?
04:38 PM Tom_L: yeah
04:39 PM JT-Shop: that shows where everything gets installed
04:39 PM JT-Shop: pin, bit ,bin files are in each directory for that card
04:39 PM Tom_L: ok so what's the primary directory before src/
04:40 PM Tom_L: usr/lib/libmesact/xxxx
04:40 PM JT-Shop: I don't understand???
04:40 PM Tom_L: i found them
04:41 PM Tom_L: /usr/lib/xxxx
04:41 PM JT-Shop: src/firmware/7i76e/*.* usr/lib/libmesact/7i76e
04:41 PM JT-Shop: from to
04:41 PM Tom_L: i was reading your github from the start of the line
04:41 PM Tom_L: brain fade
04:42 PM JT-Shop: you missed the space :)
04:42 PM Tom_L: so if i put pinfiles in there they will show up?
04:44 PM JT-Shop: better check the owner of the files once they are installed... best thing to do is sent the pin files to me or fork the repo and make local changes then make a pull request
04:44 PM Tom_L: if i do very many, i'll post them for all to see
04:45 PM Tom_L: the install didn't work the first time because i forgot to 'reinstall'
04:45 PM Tom_L: :)
04:46 PM JT-Shop: do you use the menu file download deb to get a fresh deb?
04:47 PM Tom_L: of course! you didn't put it there for the heck of it!
04:47 PM JT-Shop: lol
04:48 PM travis_farmer853: thinking maybe Tom_L needs a cup of coffee 😉
04:48 PM Tom_L: just not so linux savvy
04:52 PM JT-Shop: I thought you were a linux guru
04:52 PM travis_farmer853: i thought so too
04:52 PM Tom_L: i can stumble my way thru a few things
04:53 PM Tom_L: i haven't used it in a few months either
04:53 PM Tom_L: i can't even remember tying my shoes this morning...
04:53 PM travis_farmer853: i was more fluent in CentOS, but that took a dive, so now all my servers run Debian, and i am not so great with it...
04:59 PM JT-Shop: I can't remember the last time I tied my shoes...
05:01 PM Tom_L: can't find the directory with the script
05:01 PM Tom_L: do i need to prefact it with ./ or something?
05:01 PM Tom_L: /usr/lib/libmesact/7i80hd-16/
05:02 PM Tom_L: (as root)
05:02 PM Tom_L: nevermind
05:14 PM Tom_L: some of these firmware are pretty old
05:14 PM Tom_L: don't support the 'reload' function from mesaflash
05:22 PM _unreal_: second opinion quesation
05:23 PM _unreal_: question
05:23 PM _unreal_: https://drive.google.com/drive/folders/1PAgv2L3UJL2gOle35AczsBejKtVXsq5d?usp=sharing
05:23 PM _unreal_: My spindle holder
05:24 PM _unreal_: how would you guys mount it. I can drill holes in the mounting flanges of the spindle mount block, and TAP the Z spindle carriage plate
05:24 PM Tom_L: JT-Shop,
05:25 PM _unreal_: I can pocket the backside for the head of a bolt
05:25 PM _unreal_: and have NUTS on the spindle block
05:25 PM _unreal_: what would you guys suggest?
05:25 PM Tom_L: aviation epoxy
05:25 PM JT-Shop: Tom_L,
05:26 PM Tom_L: nearly have a set for you
05:26 PM _unreal_: any suggetions?
05:28 PM JT-Shop: prob loose connection soon... it's raining
05:28 PM JT-Shop: Tom_L, post them and I'll add them
05:29 PM Tom_L: just gotta figure out how to zip them in linux
05:29 PM JT-Shop: right click and select compress
05:31 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/JT-Shop/pinfiles/
05:31 PM Tom_L: 7i80hd
05:31 PM JT-Shop: 16?
05:31 PM Tom_L: 16
05:33 PM Tom_L: hope i didn't miss any
05:39 PM _unreal_: any thoughts on my question?
05:40 PM Tom_L: i pinned mine
05:40 PM Tom_L: and bolted it
05:41 PM Tom_L: and threaded the carriage itself. no nuts
05:42 PM _unreal_: 1/4-20
05:42 PM _unreal_: ...
05:42 PM roycroft: i have a spindle mount that i'm going to attach to a plate
05:42 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Z_Axis_Assembly1.jpg
05:43 PM _unreal_: I could try out that thread cutting bit
05:43 PM roycroft: the plate will attach to a backing plate, that will be the z axis carriage itself
05:43 PM XXCoder: tom you ever fully weld that on? I see just 4 tack welds
05:43 PM roycroft: the upper left corner of my spindle mounting plate will have a precisely drilled hole that will line up with a tapped hole in the carriage plate
05:43 PM roycroft: i'll attach that with a shoulder bolt
05:44 PM roycroft: the other three corners will have slightly oversize holes
05:44 PM Tom_L: XXCoder, of course
05:44 PM roycroft: that way i can tram the spindle mounting plate
05:44 PM XXCoder: ok
05:44 PM roycroft: and if it's tippy, i can add shims to the top or the bottm
05:44 PM roycroft: bottom
05:45 PM roycroft: it will bolt through the front, so i can make adjustments
05:45 PM Tom_L: XXCoder, i superglued it
05:45 PM XXCoder: roy also, rotation adjustable I guess
05:45 PM roycroft: that's why three of the holes will be oversize
05:46 PM xxcoder8265[m]: 🤥
05:48 PM Tom_L: xxcoder8265[m], http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Mill_Assembly2.jpg
05:49 PM roycroft: https://roycroft.us/CNC-Router/Z-Axis-Assembly-Preliminary.jpeg
05:50 PM roycroft: that's a really old drawing
05:50 PM XXCoder: yeah, was kidding on lyingface lol. (taking superglue to be literal)
05:50 PM roycroft: but you can see the front plate where the spindle mounting bracket is attached
05:51 PM roycroft: there's a second plate right behind it, where the the trucks mount
05:52 PM roycroft: i don't have the project checked out at the moment, and can't be bothered to go grab it from my gitlab server, so the really old drawing will have to suffice for now
05:52 PM roycroft: that part of the design hasn't changed, but almost everything else has
05:52 PM -!- #linuxcnc mode set to +v by ChanServ
05:52 PM -!- #linuxcnc mode set to +v by ChanServ
05:54 PM _unreal_: OOOOOOOOOOOOOOooooooooooooo ESTLcam has an entire hidden menu for setting up and doing thread milling
05:54 PM _unreal_: I can setup every aspect
05:55 PM _unreal_: ! makes me wonder if it would be worth wile to get a 3mm thread mill
05:56 PM XXCoder: threadmilling in hidden menu? wonder why its hidden
05:56 PM _unreal_: its not hidden is just a menu in a menu
05:56 PM XXCoder: ok
05:56 PM _unreal_: I have to click on "DRILL" then a sub menu has threading
05:58 PM _unreal_: https://www.bing.com/ck/a?!&&p=25f699d6dd5fd441cc7c184d1b48274bc835e7349027327637c3c5b8094e7c48JmltdHM9MTY1NDEyMTU0MiZpZ3VpZD0wMWU0ODBkMi02MTY2LTRjZWYtYjRhZi0wZDAzNDM5Yzc3MmMmaW5zaWQ9NTIwNw&ptn=3&fclid=e9109eb2-e1f7-11ec-a689-e691dcc20a05&u=a1aHR0cHM6Ly93d3cueW91dHViZS5jb20vd2F0Y2g_dj14Ty1HSEVJSU9RUQ&ntb=1
05:58 PM _unreal_: https://www.youtube.com/watch?v=xO-GHEIIOQQ
05:58 PM roycroft: yeah, that's not a link that any sane person would ever go to
05:59 PM Tom_L: _unreal_, it's a butt pucker the first time you send that threadmill down a blind hole
05:59 PM XXCoder: it redirects to youtube
05:59 PM XXCoder: tom same for tapping lol. "did I set it too low and will it impact bottom"
05:59 PM Tom_L: who the hell uses bing anyway?
06:00 PM Tom_L: XXCoder, especially since i wrote the threadmill macro also
06:00 PM XXCoder: worse, unproven program LOL
06:01 PM XXCoder: laters
06:02 PM Tom_L: JT-Cave, did you get them?
06:02 PM Tom_L: they load in the utility now too
06:02 PM Tom_L: i built them in that directory as root
06:02 PM Thorhian7490[m]: Got some machinist jacks today. I’ll need them for the steel I have to mill for the bed. Decided to try out one of the jacks on this longer piece of aluminum scrap I have laying around. It looks quite beautiful. https://cdn.discordapp.com/attachments/544360918495264798/981689650806685797/IMG_5990.mov
06:03 PM * Thorhian7490[m] uploaded an image: (1690KiB) < https://libera.ems.host/_matrix/media/r0/download/jauriarts.org/ecfkfmuxsuUeWFpOHytziPfk/IMG_5991.jpg >
06:03 PM Tom_L: that looks like a test part
06:04 PM Tom_L: and i'm not saving the .mov file
06:04 PM JT-Shop: Tom_L, yep just before I lost connection
06:04 PM Tom_L: they seem to load now
06:04 PM JT-Shop: I'll add them in the morning and push a new deb
06:05 PM Tom_L: i might be able to do a 7i90 but i dunno if that pc has a parport
06:05 PM JT-Shop: I don't have a 7i90 in the tool
06:05 PM Tom_L: you know you can just rename those?
06:05 PM Tom_L: oh
06:05 PM Tom_L: same as the 7i80 except the 80 is ethernet
06:05 PM JT-Shop: ah
06:05 PM Tom_L: 3 50pin headers
06:06 PM * JT-Shop sees the rain has let up so time to go inside
06:06 PM Tom_L: except each file will say 7i80 in it
07:05 PM _unreal_: freaking hell I looked at my thread mill the other day and now I cant find it .WTF.
07:05 PM _unreal_: I've never even used it
07:06 PM _unreal_: when I say looked at I mean like no touch just looked
07:06 PM _unreal_: sigh
07:06 PM _unreal_: I think I need beer
07:06 PM Tom_L: i took it
07:06 PM _unreal_: ve7it, hi
07:06 PM _unreal_: I'm gaana kick yoo ass
07:06 PM _unreal_: ...
07:06 PM _unreal_: after a beer
07:07 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Thread_mill2.jpg
07:07 PM Tom_L: see?
07:07 PM Tom_L: now which one is it?
07:10 PM _unreal_: grabbed a beer and just went out side and picked my pineablle
07:10 PM _unreal_: pine apple
07:11 PM _unreal_: I have 3 pineapples that are almost ready inclding the one I just picked
07:11 PM _unreal_: its still green but better to pick it before it yellows then to let it yellow and the critters go nuts for it
07:12 PM Tom_L: i just hope i picked the right ssd to clone
07:12 PM _unreal_: what size is that smallest threadmill
07:12 PM Tom_L: mine?
07:13 PM _unreal_: if those are yours o.O
07:13 PM Tom_L: 10/24 http://onlinecarbide.com/102456tpi.html
07:14 PM Tom_L: 24-56 thread
07:14 PM Tom_L: i got a full range
07:14 PM _unreal_: thinking about 3mm
07:15 PM Tom_L: the pitch is the same
07:15 PM Tom_L: it's just what will fit in the hole and clear the cutter
07:16 PM Tom_L: _unreal_, M3 what pitch?
07:16 PM _unreal_: I think .7
07:17 PM _unreal_: dont quote me
07:17 PM Tom_L: no
07:17 PM _unreal_: standard 3mm
07:17 PM Tom_L: .6 or .5
07:18 PM Tom_L: equivalent cutter for a 5-40 or 6-32
07:19 PM roguish[m]: a standard 3mm screw thread pitch is .5mm
07:19 PM Tom_L: http://onlinecarbide.com/63264tpi.html
07:19 PM Tom_L: that cutter should work then
07:20 PM Tom_L: same US drill size for tap
07:20 PM Tom_L: .098" cutter diameter
07:22 PM Tom_L: is that 2.489mm?
07:22 PM Tom_L: enter that in your tool data
07:22 PM Tom_L: i drew the profiles for my cad cam so i could verify clearance
07:25 PM Tom_L: jt's config tool looks nice
07:25 PM Tom_L: roguish[m], have you tried it?
07:26 PM roguish[m]: JT's config? for a mesacard? no.
07:26 PM roguish[m]: or his thread milling app
07:27 PM Tom_L: we wrote the threadmill thing at the same time
07:27 PM Tom_L: i did a macro for my cad cam and he wrote his app
07:27 PM roguish[m]: looked at it, but have not used it directly.
07:28 PM roguish[m]: I have used this one.... https://sct-usa.com/thread-mill-code-generator/
07:29 PM Tom_L: nice.. does both types
07:29 PM Tom_L: full is faster but not as versatile
07:33 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/arc_leadin_percent1.jpg
07:33 PM Tom_L: 3 pass cutter path for internal & external with arc leadin
07:40 PM Tom_L: well i screwed that up.. cloned the wrong drive
08:00 PM TurBoss8676[m]: 👸 🐲
08:05 PM t4nk_freenode: Tom_L, for crying out loud.
08:05 PM Tom_L: oh it's good for the soul
08:05 PM Tom_L: it's a test pc anyway
08:06 PM t4nk_freenode: lol, ... t'is now ;)
08:09 PM Tom_L: sad part is i'd just gotten it the way i wanted
08:09 PM Tom_L: but it's easy to redo
08:29 PM _unreal_: just got these in the mail. going to test them out in a few https://www.amazon.com/dp/B07F33Q6F1?psc=1&ref=ppx_yo2ov_dt_b_product_details
08:37 PM t4nk_freenode: yeah... as long as it was just cloning.. as soon as you actually destroy a disk, you get a real sinking feeling in your heart
08:37 PM t4nk_freenode: been there, of course ;)
08:38 PM Tom_L: i keep things such that it's difficult for me to shoot my foot
08:39 PM Tom_L: but not impossible :)
08:39 PM t4nk_freenode: it illustrates why it is better not to be on the command line as root all the time
08:43 PM t4nk_freenode: though not in this particular case. but errors like these could be avoided by taking better care
08:46 PM _unreal_: drilling all my holes soon as thats done cant wait to see how these new bits do
08:47 PM t4nk_freenode: those thread milling bits.. do they progress themselves along the way or no?
08:47 PM ZincBoy[CAON]066: No, you need a helical tool path to cut the thread.
08:47 PM t4nk_freenode: mmm probably not unless the z-axis moves freely
08:48 PM t4nk_freenode: ah
08:48 PM t4nk_freenode: so a bit of play, so to speak
08:49 PM ZincBoy[CAON]066: No, not even then, there is no lead angle to the teeth like on a tap. It is more or less just a double sided chamfer cutter.
08:49 PM t4nk_freenode: I see
08:49 PM _unreal_: t4nk_freenode, just look at the video I posted
08:49 PM _unreal_: https://www.youtube.com/watch?v=xO-GHEIIOQQ
08:50 PM _unreal_: shows those bits in action
08:53 PM _unreal_: FINALLY found my threadmill
08:55 PM t4nk_freenode: nice
08:56 PM t4nk_freenode: seems better than a regular tap, if you have the right bits
08:57 PM _unreal_: EBAY thats where I got it
08:59 PM ZincBoy[CAON]066: It is much slower and you need to check with a thread gauge to insure the tolerances are in spec. The upside is that a broken cutter is easy to remove and you can make oddball threads.
08:59 PM _unreal_: 1/4" solid carbide single form thread mill 20-56 tpix3/4"
08:59 PM _unreal_: that is my threadmill
08:59 PM -!- #linuxcnc mode set to +v by ChanServ
09:00 PM _unreal_: ZincBoy[CAON]066, estlcam has a complex threadmilling system
09:00 PM _unreal_: any suggestions on max or STARTING feed rate to use my thread mill? cutting 1/4-20
09:01 PM ZincBoy[CAON]066: Material?
09:01 PM Tom_L: threadmills have a very light cut
09:01 PM _unreal_: read my mind ;)
09:01 PM _unreal_: aluminum low grade
09:01 PM Tom_L: pot metal
09:01 PM Tom_L: i usually do 2 passes
09:02 PM _unreal_: I'm making the Z spindle mount carriage plate for my new cnc machine on my little cnc right now. just started drilling the pilots
09:02 PM Tom_L: and i don't push mine very hard
09:02 PM _unreal_: IPM MMPM?
09:02 PM _unreal_: I run mm, and my spidnle does 15k rpm
09:02 PM Tom_L: can't look right now, i'm booted on another drive on that pc
09:02 PM _unreal_: my BABY brushless
09:02 PM _unreal_: spindle :)
09:03 PM Tom_L: if you feed it proper at that rpm it'll make you pucker right up
09:03 PM Tom_L: i'd slow it down
09:03 PM _unreal_: ?
09:04 PM _unreal_: the onlything I listed is my RPM
09:04 PM Tom_L: now where was i...
09:04 PM _unreal_: and my spindle does not like to go below... .... 13k
09:05 PM ZincBoy[CAON]066: 15k rpm is fine, 21ipm feed would be optimal but I would dial that back a fair bit. Coolant or air blast to flush the chips would be needed.
09:06 PM _unreal_: my machine rapids at 600mm/min
09:06 PM _unreal_: so ya I'd half or 1/4 that feed rate
09:07 PM _unreal_: I'd prob go 5-10 ipm then
09:07 PM _unreal_: UGH... so many pilot holes
09:16 PM _unreal_: ooooOOO I like these new bits
09:16 PM _unreal_: they eat soft aluminum like butter
09:16 PM _unreal_: running 150mm
09:16 PM _unreal_: on my TINY machine
09:19 PM ZincBoy[CAON]066: It is always great when you find a cutter that just works on your machine.
09:23 PM _unreal_: ZincBoy[CAON]066, good lord hehe thats with my original Z setup as well. before I got MGN15's https://drive.google.com/file/d/1Epi_HnCUA83Bbr7-sbDEt4EFKLzObQoM/view?usp=sharing
09:30 PM _unreal_: yep those bits are freaking amazing
09:30 PM _unreal_: t4nk_freenode, those amazon bits I just posted are amazing
09:41 PM t4nk_freenode: well, like common knowledge dictates: when it comes to tools, the cheaper the better ;)
09:42 PM t4nk_freenode: I'll have some time later on to mess with my build...
09:43 PM _unreal_: ?
09:44 PM t4nk_freenode: I switched back from the plywood base to the mdf one of my first build
09:46 PM t4nk_freenode: got the homing/ limit switches in position, but now my diy switch got a severed lead
09:47 PM t4nk_freenode: after that I want to align the y-axes and fix it firmly
09:55 PM XXCoder: lol. someone posted this picture https://i.redd.it/8xqdizkna4391.jpg
09:56 PM XXCoder: man, if its not machine I used to run, its amazing conence since table looks very close too
09:56 PM roycroft: that looks very fluffy
09:56 PM XXCoder: yeah nylon
09:56 PM XXCoder: if it is indeed same machine, I know what part it was
09:57 PM XXCoder: AND I know machine flaws. its kinda broken, so z movement is very slow. if it moves too fast, counterwieght bounces and z becomes unknown
09:59 PM XXCoder: chev machine
09:59 PM Tom_L: well i'm almost back to where i was before i cloned the wrong drive :)
09:59 PM XXCoder: chev is what we called it, though forgot full name.
10:00 PM roycroft: i got another four drawers glued up today
10:00 PM roycroft: i shall be able to finish and install them tomorrow
10:01 PM roycroft: i need to keep up this pace every day without fail if i want to complete the project before the country fair
10:04 PM _unreal_: XXCoder, hay look razor sharp confetti
10:04 PM roycroft: dinner was at an izakaya tonight
10:04 PM roycroft: a great time was had by all
10:04 PM _unreal_: roycroft, godbless you
10:04 PM XXCoder: _unreal_: looks like nylon
10:04 PM _unreal_: ya
10:04 PM _unreal_: still sharp looking
10:04 PM XXCoder: you can grab it no issues. unless machine had few chips from last job lol
10:04 PM _unreal_: at least pointy
10:05 PM roycroft: shochu, sake, and lots of small plates
10:08 PM Tom_L: grabbing webpack again
10:08 PM Tom_L: 6g
10:09 PM Tom_L: 14.7 & 9.2
10:14 PM _unreal_: doing a PEEL right now facing the surface for the spindle mounting bracket
10:14 PM _unreal_: if there is time, I'll mill out the root holes for the 10 holes that will be 1/4-20
10:15 PM _unreal_: root hole=root size hole for 1/4-20 thread
10:24 PM _unreal_: BLAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA fuck me
10:24 PM _unreal_: just discovered I fucked up
10:24 PM _unreal_: making din
10:24 PM _unreal_: LATE din. and I mixed up cinnimon for paprika
10:24 PM _unreal_: in one of the things I'm making
10:24 PM _unreal_: BLAAAA
10:31 PM roycroft: if it was cinnamon when you meant paprika, that could actually turn out well in some cases
10:32 PM roycroft: the other way around, not so much
10:53 PM roycroft: *sigh* i need to stop reading the news
10:53 PM roycroft: another day, another mass shooting
10:54 PM XXCoder: yeah
11:09 PM _unreal_: so final verdict, that new milling bit is amazing
11:39 PM CaptHindsight[m]: I call COMED (power co) at 3:45pm, they have a truck out by 6pm and are already planning on replacing our buildings transformer due to brownouts, it's a 2MW transformer!
11:40 PM CaptHindsight[m]: I should have called last year
