12:18 AM xxcoder: ugh night is going to suck. 76f still\
12:50 AM Deejay: moin
05:57 AM lcnc-relay: <meisterdippel@> hello
06:13 AM Tom_L: morning
06:32 AM lcnc-relay: <pink_vampire@> MY CNC is up and running!!
06:32 AM lcnc-relay: But my mini multimedia keyboard that I modified the key mapping for it didn't survive..
06:32 AM lcnc-relay: So I connected a regular keyboard and I am not remember how I change the arrows directions and the keyboard keys right now volume up volume down control the Z axis, and the X and Y axis move to the opposite side, if I click the left arrow the spindle move to the right.
06:32 AM lcnc-relay: It mill correctly, so I know the configuration of the motors is correct.
06:46 AM lcnc-relay: <pink_vampire@> Apparently I think I edited the axis file..
06:56 AM lcnc-relay: <pink_vampire@> I fixed it!
06:59 AM lcnc-relay: <rs> pink_vampire@: keeping that stuff in git or similar would be good practice. commit often.
07:00 AM lcnc-relay: <pink_vampire@> The machine is not even connected to the internet
07:00 AM lcnc-relay: <pink_vampire@> I try to remember how I changed the color of the tool path.
07:01 AM lcnc-relay: <pink_vampire@> But I agree with you, I need to have better documentation
07:08 AM lcnc-relay: <rs> git doesn't need any internet
07:09 AM lcnc-relay: <rs> someting like tiddlywiki or trilium notes https://github.com/TriliumNext/Trilium also helps to document stuff and keep a log.
07:10 AM lcnc-relay: <rs> or any of the gazillion of other note taking apps ;)
07:11 AM lcnc-relay: <pink_vampire@> That is SUPER NEAT!!
07:16 AM lcnc-relay: <rs> hope I didn't send you into a rabbit hole... :-)
07:26 AM lcnc-relay: <pink_vampire@> Right now I take pictures of the screens
07:27 AM lcnc-relay: <pink_vampire@> But to be honest I never imagined that I will not going to have my CNC machine for several years and my life will change from end to end
08:47 AM -!- #linuxcnc mode set to +v by ChanServ
10:17 AM lcnc-relay: <.le_potato@> today is probe time!
10:17 AM lcnc-relay: <.le_potato@> but i have to wire tool touch thing as well
10:18 AM lcnc-relay: <.le_potato@> and i dont know that how
10:19 AM * roycroft needs to work on his e-stop and classic ladder next, but does not know when he'll be able to do that
10:28 AM roycroft: and the red flag warning has been reissued, effective 9am to 9pm today
11:11 AM JT-Shop: nap time
11:16 AM xxcoder: morning
11:16 AM xxcoder: vloud so far it seems
11:17 AM xxcoder: cloudy
11:24 AM roycroft: it's overcast here
11:24 AM lcnc-relay: <Mister Wallace> Alrighty so, I cracked open the Bandit and got some pictures of the driver board (connections)
11:24 AM lcnc-relay: <Mister Wallace> https://jauriarts.org/_heisenbridge/media/matrix.org/iLBTxGLeMcmYRBFJKVKDkdmH/bt8A1wmxE3Y/IMG_0422.jpeg

11:26 AM lcnc-relay: As we can see there’s lots of documentation available /s
11:28 AM lcnc-relay: <Mister Wallace> Looks like that ribbon is the only input
11:28 AM xxcoder: oh boy. being unique is fun in many ways, but machine being unique just make things harder
11:30 AM lcnc-relay: <Mister Wallace> Any fresh thoughts on connecting that situation to the 7196?
11:35 AM xxcoder: far from expert, but I guess best step to do is reverse engineering it to find what pins do what, etc
11:35 AM xxcoder: assuming its orginal board works
11:36 AM lcnc-relay: <Mister Wallace> Yeah the original board works
11:37 AM lcnc-relay: <Mister Wallace> Not sure reverse engineering this is worthwhile right now when I could definitely buy modern drivers
11:38 AM xxcoder: dont know either
11:38 AM lcnc-relay: <roguish> Mister Wallace: start a simple wiring diagram. and control system layout sketch
11:39 AM lcnc-relay: <Mister Wallace> Suppose I should also check if the documentation I’ve got lists what the pins do
11:40 AM lcnc-relay: <roguish> yup. and use your scope and vom to check 'em
11:40 AM lcnc-relay: <roguish> it's important, whether you stay with the present drivers and motors, or go new ones
11:41 AM roycroft: iirc your motors are fairly high current, and as such you may have trouble finding new drivers for them
11:41 AM lcnc-relay: <roguish> the better the diagram and knowledge, the less magical smoke comes out
11:41 AM roycroft: and if your current drivers work, consider keeping them
11:41 AM lcnc-relay: <roguish> I agree with Roy
11:43 AM lcnc-relay: <Mister Wallace> I’ve been able to find drivers for up to 8.2A, but not the listed 9.2A
11:44 AM lcnc-relay: <roguish> Mister Wallace: may be ok. you're not going after a high production shop machine. just a hobby shopper
11:45 AM roycroft: i would focus your energy on finding documentation or documenting the driver interface, so you can use the existing hardware and drive it from the mesa board instead of whatever it came with
11:45 AM roycroft: as i suggested yesterday, i'd recommend getting linuxcnc talking to your existing machine before swapping out the drivers and motors
11:46 AM lcnc-relay: <roguish> ditto
11:47 AM * roycroft says that as someone who inherited a much smaller machine and is doing exactly that, in spite of several folks' recommendation that he swap the cheap chinese drivers for gecko drives
11:47 AM roycroft: i'm walking my talk
11:50 AM lcnc-relay: <Mister Wallace> Understood, currently trying to gauge how much of a project I’m willing to undertake right now vs. retrofitting with new hardware (presumably a smaller but still significant undertaking)
11:52 AM lcnc-relay: <Mister Wallace> The primary project for me here is the thing I’d like to make parts for using the mill, not the mill itself
11:56 AM rdtsc-w: it's easy to get lost in possible upgrades... maybe a good idea is to keep things as simple as possible - can always upgrade stuff later
12:00 PM lcnc-relay: <Mister Wallace> Right, but what’s your definition of simple in this context?
12:00 PM lcnc-relay: <Mister Wallace> For me simple implies replacing the drivers & steppers
12:01 PM lcnc-relay: <Mister Wallace> Rather than reverse engineering older hardware
12:07 PM JT-Shop: I've converted two machines and used the old drives and motors and power supplies on both
12:07 PM JT-Shop: so I just removed the old controller boards and wired up my mesa boards to the drives and the i/o
12:07 PM lcnc-relay: <Mister Wallace> Any specific board recs based on the above pics?
12:08 PM lcnc-relay: <Mister Wallace> I’m not against trying that, I’m just worried about how long it would take /me/ to do it
12:09 PM roycroft: mister wallace: it should be fairly straightforward to figure out how to interface with your current drivers
12:10 PM roycroft: stepper motor control is pretty simple, unless you have some big proprietary mess of a thing going on
12:11 PM roycroft: says the person who took forever to figure out that setting the enable pin disables the driver, and turning off the enable pin enables the driver
12:11 PM lcnc-relay: <Mister Wallace> I mean, if you’re willing to guide me through it as needed then that’s worth a shot
12:11 PM lcnc-relay: <Mister Wallace> Just need to figure out which board from JT-Shop
12:11 PM roycroft: we discussed this before - the 7i96s is likely a good candidate
12:11 PM JT-Shop: yup I ran into that with my anilam 1100m conversion the drive enable needed to be grounded to enable the drives
12:12 PM lcnc-relay: <Mister Wallace> roycroft: Apparently the S or EU will be the choice depending on the IO
12:14 PM JT-Shop: the drives what little I can see are similar in design to my anilam 1100m except the 1100m is servo drives
12:14 PM JT-Shop: so is there a board for each axis?
12:14 PM lcnc-relay: <Mister Wallace> There is a board for each axis yes
12:14 PM JT-Shop: https://www.forum.linuxcnc.org/30-cnc-machines/29745-shizuoka-an-s-retrofit-advice-needed
12:15 PM lcnc-relay: <Mister Wallace> https://jauriarts.org/_heisenbridge/media/matrix.org/bgrWwgjCaxKNkHOhObEVryYi/zL303QHPt7s/IMG_0423.jpeg
12:15 PM lcnc-relay: <Mister Wallace> JT-Shop: How ‘bout that… same bandit retrofitted by the same company as mine
12:16 PM roycroft: i think the 7i76eu has more io pins than the 7i96s, but the two are otherwise similar
12:16 PM JT-Shop: that last photo looks like 3 driver boards and on the left a DC power supply maybe
12:17 PM * JT-Shop heads to the other shop to work on the bandsaw mobility project
12:18 PM lcnc-relay: <Mister Wallace> JT-Shop: I believe this is correct.
12:18 PM roycroft: if i'm honest, besides being simpler to just interface with the existing hardware than to replace everything, that controller is an impressive bit of discrete component technology, in outstanding condition, and i would hate to just toss something like that
12:18 PM roycroft: i would do whatever i could to make it work again
12:19 PM lcnc-relay: <Mister Wallace> The Bandit works currently - it’s just extremely slow to take code via serial at the best of times. It’s also very unreliable.
12:19 PM roycroft: and those drivers have six wires going to them, which is what one would expect
12:19 PM lcnc-relay: <Mister Wallace> The 6 wires on terminals are the output to the steppers
12:20 PM roycroft: oh, ok
12:20 PM roycroft: have you found the inputs?
12:20 PM lcnc-relay: <Mister Wallace> Like I mentioned yesterday one other appealing point to replacing the drivers is the ability to leave this Bandit attached, apparently people do need them from time to time.
12:20 PM lcnc-relay: <Mister Wallace> roycroft: It’s that ribbon
12:20 PM lcnc-relay: <Mister Wallace> https://jauriarts.org/_heisenbridge/media/matrix.org/IXkZJmlIaCoRULWARpsawfMr/pE_pGLInBKM/IMG_0426.jpeg
12:20 PM lcnc-relay: (That ribbon)
12:21 PM lcnc-relay: <Mister Wallace> Like I mentioned yesterday one other appealing point to replacing the drivers is the ability to leave this Bandit intact, apparently people do need them from time to time.
12:21 PM lcnc-relay: <Mister Wallace> Each driver has one of those ribbons coming from the bandit’s logic board
12:21 PM roycroft: so my desire for preservation of the controller is accomodated by your willingness to replace the entire controller?
12:22 PM roycroft: not that my desire has any meaning to you :)
12:23 PM lcnc-relay: <Mister Wallace> roycroft: Yes, and to be clear it’s my desire too
12:23 PM lcnc-relay: <Mister Wallace> There’s TONS of space in the two electrical cabinets to put replacement hardware
12:23 PM roycroft: those ribbon cables have an awful lot of conductors for signalling stepper motor drivers
12:24 PM lcnc-relay: <Mister Wallace> Frankly I sorta want to replace the two cabinets with one larger one that doesn’t get in the way of coolant pump access, I don’t know what they were thinking retrofitting a second cabinet that makes the coolant pump impossible to service.
12:24 PM roycroft: are there encoders as well?
12:24 PM lcnc-relay: <Mister Wallace> roycroft: Not that I’ve found
12:25 PM roycroft: and you have sufficient motor documentation, iirc, to know if the motors have integral encoders or not
12:26 PM pcw-home: There are Bandits with linear scales and DC motors, but this seems to be a stepper version
12:26 PM roycroft: i think finding 9+a drivers is your biggest challenge, should you decide to replace all of that
12:26 PM lcnc-relay: <Mister Wallace> pcw-home: Can confirm the lack of linear scales
12:26 PM lcnc-relay: <Mister Wallace> roycroft: Yeah no dice there, only 8.2A drivers.
12:28 PM roycroft: and as was mentioned earlier, if you can live with 8.2a instead of 9+a that would work
12:30 PM roycroft: you would not be able to take abom cuts and enter your swarf in the chip of the month contest
12:30 PM roycroft: but you should be able to make parts
12:31 PM lcnc-relay: <Mister Wallace> Yeah I can definitely live with 8.2A. Especially with the option to later upgrade the steppers, like the person in that forum post did.
12:32 PM lcnc-relay: <Mister Wallace> https://www.geckodrive.com/product/gr214v-bulletproof-high-resolution-stepper-drive/ so, what breakout board to pair with these?
12:33 PM roycroft: the 7i96s would work with those
12:34 PM lcnc-relay: <Mister Wallace> JT-Shop do you offer local pickup? 😅
12:39 PM JT-Shop: you can pickup my CHNC it's for sale
12:40 PM JT-Shop: and it's already got linuxcnc
12:40 PM JT-Shop: I had a local guy pickup a board here once
12:51 PM lcnc-relay: <skunkworks8841@> If the control works - probe the logic going to the drive.. figure out what signals it needs. (you could probably test it with a printer port bob initally...
12:52 PM lcnc-relay: <Mister Wallace> JT-Shop: Your what?
12:53 PM lcnc-relay: <Mister Wallace> JT-Shop: I might do the same
12:54 PM roycroft: mister wallace: you would have to be willing to entertain the chickens if you want to pick it up in person
12:55 PM roycroft: they, and jt, might take it as an affront if you do not do so
12:56 PM JT-Shop: roflmao
12:56 PM JT-Shop: https://www.facebook.com/marketplace/item/1439553370431970
12:56 PM xxcoder: is there such thing as chicken teaser? ;)
12:57 PM JT-Shop: my buddy that watches them when I'm gone is my assistant chicken tender
12:57 PM xxcoder: thats cool lathe
12:57 PM JT-Shop: thanks
12:57 PM roycroft: xxcoder: it's called "food"
12:57 PM xxcoder: lol
12:57 PM JT-Shop: it needs a new zip code
12:58 PM lcnc-relay: <Mister Wallace> roycroft: Oh I’m down
01:02 PM roycroft: my new portable garage is out for delivery
01:03 PM * roycroft will be able to start work on the new roof after that arrives and is assembled
01:06 PM JT-Shop: which one did you get?
01:07 PM lcnc-relay: <Mister Wallace> JT-Shopwant to convert the Hardinge HCT I’ve got in storage? 😅
01:07 PM JT-Shop: no
01:07 PM roycroft: me?
01:07 PM JT-Shop: yes you
01:08 PM roycroft: a cheap one
01:08 PM roycroft: https://www.amazon.com/dp/B0D72DS7QK
01:08 PM lcnc-relay: <Mister Wallace> JT-Shop: Me neither
01:08 PM roycroft: my current one is 20+ years old, and is leaking a little bit
01:09 PM roycroft: i need one that is water tight for another year or two, until i can build the extension to my shop
01:09 PM pcw-home: If you wanted to use the old drives, you would really need a manual/schematic
01:09 PM roycroft: so the plan is to remove the sides of the current one, move it out onto my driveway, and use that for doing the joinery work for my new roof
01:10 PM roycroft: and install the new one where the old one is now
01:10 PM lcnc-relay: <Mister Wallace> pcw-home: Me?
01:10 PM roycroft: then, when the roof project is done, i'll sell or give away or recycle the old one
01:11 PM pcw-home: Yeah
01:11 PM xxcoder: wouldnt just reusing old one, but with tarps re-covering the roof be cheaper?
01:11 PM roycroft: not much cheaper
01:12 PM lcnc-relay: <Mister Wallace> pcw-home: I have the manual and schematic, but at this point planning to buy new drives to keep the Bandit intact.
01:12 PM roycroft: and i want a covered work area while prepping the timbers for the new roof
01:12 PM xxcoder: ok
01:12 PM roycroft: the side plates will be 16' 6x8s
01:12 PM roycroft: so i need a pretty big covered area for that
01:12 PM lcnc-relay: <Mister Wallace> roycroft: I’ll happily use the old one as a dusty room for my sand blaster…
01:12 PM roycroft: the cross beams will also be 16'
01:14 PM roycroft: the current portable garage abuts the front of my shop, too, and i need some space, so the new one will be installed about 6' away from the shop
01:15 PM roycroft: i'll have to move a bunch of stuff to make that work
01:15 PM roycroft: i need to get all that prepped by this weekend, so i can order lumber on tuesday to pick up later next week
01:15 PM pcw-home: Any opencart experts here?
01:16 PM roycroft: i looked at it once, and forget why i decided not to use it
01:16 PM JT-Shop: I used to do opencart years ago but switched to woocommerce
01:16 PM roycroft: i mostly use woocommerce these days
01:16 PM JT-Shop: not sure if I even remember how to drive opencart
01:17 PM roycroft: i forget what i was using when i managed drupal sites
01:17 PM pcw-home: Yeah, I suspect our hosting company updated something (PHP version) and broke opencart
01:18 PM roycroft: that happens far too often
01:19 PM roycroft: we have customers who have old code that won't run on current php versions
01:19 PM JT-Shop: store.mesanet.com ?
01:19 PM roycroft: i've had to install multiple php versions on our web servers because of that
01:19 PM roycroft: i use the suny repository, and have 7.4, 8.2, and 8.3 installed on our web servers
01:19 PM roycroft: a simple directive in the website's config file designates which php version to use
01:20 PM roycroft: i hate doing that, but i hate customer websites breaking even more
01:21 PM roycroft: my initial, not knowing opencart, suggestion is to enable php debugging on your website and see what errors pop up on the screen
01:21 PM roycroft: that should give you a clue as to what to do next
01:21 PM pcw-home: Yeah our hosting company disabled 7.x because of security concerns so we had to have opencart 3.x patched for 8.x compatibility a couple years ago but this just happened
01:21 PM roycroft: or, if you have access to your logs, check the error log
01:21 PM roycroft: i believe the latest debian release ships with php8.4
01:22 PM roycroft: so if they did an os upgrade recently they may have upgraded php as well
01:22 PM roycroft: and yes, php can break when you do a minor release upgrade
01:22 PM pcw-home: No info in the normal admin logs, there are other logs I will need to look at via cpanel
01:22 PM roycroft: look at the web server error log, if you can
01:23 PM roycroft: the smoke is back
01:24 PM pcw-home: Ill take a look later today, my suspicion is that our hosting company upgraded php8.x to 8.4
01:24 PM roycroft: i had a window open in the living room, because it is not hot yet, and i wanted the cats to get some fresh air
01:24 PM roycroft: now the living room smells like smoke
01:24 PM xxcoder: I really do need to get aqi montiors for home. I cant smell
01:24 PM roycroft: the window is closed, but it will take a couple or three ac cycles to get rid of the smell
01:25 PM roycroft: maybe i'll run the fan manually for a while
01:25 PM lcnc-relay: <Mister Wallace> Any opinions between these two?
01:25 PM lcnc-relay: https://www.geckodrive.com/product/gr214v-bulletproof-high-resolution-stepper-drive/
01:25 PM lcnc-relay: https://www.omc-stepperonline.com/digital-stepper-driver-0-5-8-2a-180-240vac-for-nema-34-42-stepper-motor-dm2282t
01:26 PM roycroft: aqi is 138 and rising
01:27 PM roycroft: oddly, right by the fire (and in a direct path from here to the fire) the aqi is only 90
01:27 PM roycroft: it's 157 just on the other side of the mountains
01:28 PM roycroft: actually it's 229 just over the pass
01:28 PM roycroft: not to self: do not go to central oregon today
01:28 PM roycroft: note
01:28 PM JT-Shop: for a few bucks more I'd go with gecko
01:29 PM roycroft: i would go with the gecko as well
01:29 PM lcnc-relay: <Mister Wallace> Gecko it is then
01:29 PM roycroft: they are more robust, have more features, and are better supported
01:29 PM roycroft: so there's three reasons
01:30 PM lcnc-relay: <Mister Wallace> Any recs for a power supply for the 7I96+geckos?
01:30 PM roycroft: well there's the rub
01:30 PM JT-Shop: check the power supply in the machine for the steppers
01:30 PM lcnc-relay: <Mister Wallace> Oh?
01:30 PM roycroft: iirc your motors are extremely low voltage, and fairly high current
01:31 PM lcnc-relay: <Mister Wallace> Yep
01:31 PM roycroft: most stepper motors are much higher voltage and lower current
01:31 PM lcnc-relay: <Mister Wallace> I do want to future proof this for later new steppers
01:31 PM roycroft: you might have a hard time finding a 5v, 30a psu
01:32 PM roycroft: honestly, if you're thinking about that, you should replace the motors at the same time you replace the drivers
01:32 PM lcnc-relay: <Mister Wallace> https://jauriarts.org/_heisenbridge/media/matrix.org/vztSRrTOagGIKpLGHQmLYoCw/f8xCniIEvh4/IMG_0428.png
01:32 PM lcnc-relay: …about that
01:33 PM roycroft: that would work for now
01:33 PM roycroft: when you get new motors you'll almost certainy need a new psu
01:33 PM roycroft: but not new drivers
01:34 PM pcw-home: You should be able to use your existing power supply (45V?)
01:34 PM lcnc-relay: <Mister Wallace> Good thing this is cheap and they’ve got 4 of them, I’ll pick ‘em up
01:34 PM lcnc-relay: <Mister Wallace> pcw-home: Trying to leave the Bandit intact and just disconnect it
01:35 PM lcnc-relay: <Mister Wallace> And the existing supply is in the Bandit
01:36 PM pcw-home: OK so then get a say 48V to 80V for the Gecko, the 7I96S just needs say 0.5A
01:36 PM pcw-home: @ 5V
01:37 PM pcw-home: you may want an intermediate supply (24V) for switches etc
01:38 PM lcnc-relay: <Mister Wallace> I’ll start planning out a new cabinet and go from there - need power for the drawbar too
01:40 PM lcnc-relay: <Mister Wallace> Any software recs for electrical layout?
01:41 PM lcnc-relay: <.le_potato@> sometimes when i press home it jumps 1.4mm up
01:41 PM lcnc-relay: <.le_potato@> but not all the time, what am i missing?
01:42 PM lcnc-relay: <Mister Wallace> Actually, can’t I use an output off the VFD for switches/control lights?
01:44 PM roycroft: if i recall, mister wallace's motors say they are 2.2v
01:45 PM roycroft: which is ridiculously low
01:45 PM lcnc-relay: <Mister Wallace> https://jauriarts.org/_heisenbridge/media/matrix.org/fHwNyLRmOFJheZGoJnpRjpVA/3JL5lMtIZfU/IMG_0323.jpeg
01:45 PM roycroft: maybe measure the output voltage on the bandit's motor psu?
01:45 PM lcnc-relay: (Stepper spec)
01:46 PM pcw-home: 2V is not terribly low for a step motor(I think the Bandits supply was 45v)
01:47 PM roycroft: i keep getting emails (several daily) inviting me to subscribe to ai software that would write code for me
01:48 PM roycroft: i keep being not interested
01:48 PM pcw-home: 2-5V is a normal range for step motors (there are high impedance motors like 24V but only for very small loads)
01:50 PM rdtsc-w: steppers are all about current, and how quickly you can get that current to switch
01:50 PM rdtsc-w: current = torque
01:54 PM lcnc-relay: <Mister Wallace> So that 5V 55A supply should work, no?
01:54 PM Tom_L: with a few A to spare
01:54 PM lcnc-relay: <skunkworks8841@> so you want the voltage much higher than stepper voltage. Usually 20 to 30 times. (but you should calculated it from the stepper inductance)
01:55 PM lcnc-relay: <skunkworks8841@> lol - you welding?
01:56 PM * roycroft is confused, but that is not unusual
01:58 PM Tom_L: Stepper motor's nameplate voltage ratings indicate the DC voltage at which the motor's coils will draw the rated current due to coil resistance alone, but they are designed for use with a chopper drive
01:58 PM roycroft: hmm, laphroaig just invited me to purchase one of their new, 39-year limited edition whiskys
01:58 PM roycroft: it's only £4950 for a 700ml bottle
01:58 PM roycroft: but that includes vat
01:58 PM roycroft: so not so bad :)
01:59 PM JT-Shop: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Stepper_Formulas
01:59 PM roycroft: and dear leader just discovered that the scots make whisky, that folks in this country like it, and that there's a tariff on it
01:59 PM roycroft: but he's not done anything about that tariff
01:59 PM JT-Shop: you need to read that page before buying a power supply for the steppers
01:59 PM roycroft: so i guess it gets expensive to imp;ort it
02:00 PM roycroft: probably cheaper to fly to scotland and drink it there
02:01 PM roycroft: i think that even if i were the 1% i would not spend £5000 on a bottle of scotch
02:01 PM roycroft: as much as i love a good single malt
02:03 PM roycroft: on that wiki page, does "temperature rise" mean "rise to temperature" or "rise above ambient temperature"?
02:03 PM roycroft: because if it's 20 degrees in your air-conditioned shop, an 80 degree rise is 100 degrees
02:06 PM JT-Shop: you would have to ask the person that wrote that page
02:09 PM Tom_L: rise from where it starts to where it levels off
02:38 PM * roycroft remembers now calculating the maximum voltage for some stepper motors
02:41 PM * JT-Shop doesn't remember doing the calculations for the steppers on the plasma 18 years ago
02:41 PM JT-Shop: https://www.youtube.com/watch?v=e70jdiDm7yc
03:04 PM JT-Shop: hmm my 1/2" Forstner bit drills about 5 thou undersize
03:10 PM * JT-Shop finds a 0.751" reamer but needs to turn the shank down to 0.500000"
04:04 PM roycroft: aqi is 190 now
04:04 PM roycroft: it's not safe to work outdoors
04:04 PM roycroft: and i have to work outdoors today
04:04 PM roycroft: i'll wear a mask
04:07 PM xxcoder: good idea. you will never know how having bad lungs is like at that rate
04:22 PM xxcoder: hm red flag warning here. with cloud cover and dang cool weather
04:22 PM xxcoder: no wind too
04:35 PM roycroft: weird
04:35 PM roycroft: i have a book on order that is due to arrive on saturday
04:35 PM roycroft: amazon just refunded me because it is "late"
04:36 PM roycroft: i did not ask them to do that or contact them in any way about the order
04:36 PM xxcoder: previous or next sat?
04:36 PM roycroft: this coming saturday, the 30th
04:36 PM xxcoder: odd
04:36 PM roycroft: that's both what the order says and what the usps tracking system says
04:42 PM roycroft: this season's covid vaccines were just approved by the fda, but with severe restrictions
04:42 PM roycroft: most people under 65 will not be eligible to get it
04:42 PM xxcoder: bah
04:42 PM * JT-Shop sorta remembers 65
04:42 PM roycroft: so i guess we should expect a covid epidemic this winter in the us, while the rest of the world stays safe
04:43 PM roycroft: it might affect you anyway, jt-shop, because if there's an epidemic there will be so much covid around that the vaccine will be less effective than it otherwise would be
04:44 PM * roycroft stocks up on bleach and horse tranquilizers
04:48 PM roycroft: but at least old man crackerbarrel is back
04:48 PM roycroft: this country definitely has its priorities straight
04:48 PM * roycroft had never heard of cracker barrel until the recent "controversy"
04:48 PM roycroft: it must be a back east or southern thing
04:51 PM lcnc-relay: <pink_vampire@> Mister Wallace: I am using the gecko G320x dc servo drivers, on my milling machine, the company is solid, and they helped me several times.
04:54 PM lcnc-relay: <Mister Wallace> pink_vampire@: What made you go with servos out of curiosity? I was considering it as well, seems like they could reach the torque I need
04:59 PM lcnc-relay: <pink_vampire@> I wanted the best, and my husband just ordered a kit of 4 nema 34 dc servos, and yeah they are abit bigger for my x and y for my mill (g0704 with servo spindle), but I like it that I know it move accurate and no steppes are missing.
04:59 PM lcnc-relay: right now I am working on a cnc router and I am using the TB6600 drivers (about $10 per driver) these are 5A drivers, and so far so good, it is a belt driven system, so no crazy forces are expected, all I need it is to cut sheets of wood.
05:01 PM xxcoder: nice. roy had issues with tb6600s just stopping after certain distance. turns out lowering amps on drivers solved that issue pink
05:01 PM xxcoder: so yeah keep that in mind if it stops after certain distances for you too.
05:01 PM xxcoder: roy had tb6600s on 3.5a limit, and he lowered it to 2.5a
05:05 PM roycroft: i also was feeding the drivers more voltage than the were rated for
05:05 PM roycroft: and i reduced that to within spec
05:05 PM lcnc-relay: <pink_vampire@> the problem with all the drivers G320x and the tb6600, the terminals eventually melt and you get poor connection
05:05 PM lcnc-relay: so I de-solder them and solder the motor wires directly to the pcb.
05:05 PM roycroft: i've not run into that yet, but i'm still early on in my testing
05:06 PM roycroft: https://roycroft.us/MiniRouter/MiniRouterTest.mov
05:06 PM lcnc-relay: <pink_vampire@> if you want I can go down to the garage and take some pictures
05:06 PM roycroft: that is from yesterday, before i reduced the current to 2.5a
05:06 PM roycroft: a few goes of that routine and the drivers would start shutting themselves down until i did the current reduction
05:06 PM lcnc-relay: <Mister Wallace> pink_vampire@: Very cool, thanks!
05:07 PM xxcoder: yeah kinda curious what your mill looks like now. been few years
05:13 PM roycroft: the thing is, though, i think there are about a bazillion different "tb6600" drivers floating around
05:14 PM roycroft: i suspect internally there are a lot of differences
05:14 PM roycroft: so my experience with the ones i happen to have may not translate to others
05:14 PM lcnc-relay: <.le_potato@> oh it was tool offset
05:14 PM xxcoder: roy indeed
05:15 PM roycroft: aqi has "improved" to 171
05:15 PM xxcoder: its why I told pink to keep in mind in case she have same issue
05:15 PM xxcoder: 65 aqi here, the worse for this summer so far
05:15 PM roycroft: i really need to get started on the roof project
05:15 PM xxcoder: no wonder I felt bit poorly for couple days
05:15 PM roycroft: but i'm not excited about working outdoors, even with a mask
05:16 PM roycroft: i need to load a bunch of stuff that's in the old portable garage onto my pickup and take it over to storage temporarily
05:16 PM roycroft: and that's a fair amount of physical work
05:17 PM lcnc-relay: <pink_vampire@> Why I can't send here any pictures?
05:19 PM roycroft: ok, the emigrant fire has gotten a lot bigger
05:19 PM roycroft: it's south of here, and we have southerly winds today
05:19 PM roycroft: so that must be where the smoke is coming from
05:19 PM xxcoder: bridge dont work properly with images, need to use either offtopic or use image host
05:19 PM roycroft: it's 7700 acres now
05:20 PM xxcoder: https://imgbb.com/
05:20 PM * Tom_L mentions linuxcnc as a reminder where he is
05:22 PM roycroft: pink_vampire is trying to upload linuxcnc-related images right now
05:22 PM Tom_L: kinda gets hard to weed out conversations with all the cruft
05:22 PM roycroft: we're staying mostly on-topic
05:22 PM Tom_L: not lately
05:22 PM roycroft: other than the weather/fire discussions
05:24 PM lcnc-relay: <.le_potato@> http://6-f.cc/nc/index.php/s/EDSMx8WdDGkdE6f
05:25 PM lcnc-relay: <.le_potato@> milled brake disc
05:25 PM Tom_L: for cooling
05:26 PM xxcoder: I guess also to have spots to hold dust
05:26 PM xxcoder: so grip is better
05:50 PM lcnc-relay: <pink_vampire@> https://imgur.com/a/6HGBX7W
05:51 PM lcnc-relay: <pink_vampire@> here are some pictures of my stuff..
05:51 PM lcnc-relay: and the G320X and TB660 hard wired
05:51 PM xxcoder: thats pretty cool
05:51 PM xxcoder: mill have changed quite a bit
05:56 PM lcnc-relay: <pink_vampire@> I still need to wire the lathe / milling head back, or better to change the motor to a DC motor (basically the old stock spindle of the g0704)
05:58 PM lcnc-relay: <Mister Wallace> https://jauriarts.org/_heisenbridge/media/matrix.org/WwiEZJXzVHekDdqWRLdbXVTC/rRZDGP9vi3I/IMG_0429.jpeg
05:58 PM lcnc-relay: I only just noticed the existing drivers on the Shizuoka are labeled as 45V input
05:59 PM lcnc-relay: <roguish> get out your VOM and check 'em
05:59 PM lcnc-relay: <Mister Wallace> Will do (when I get home)
05:59 PM lcnc-relay: <roguish> 👍️
06:01 PM lcnc-relay: <Mister Wallace> One PSU for all 3 steppers or 1 each?
06:01 PM lcnc-relay: <Mister Wallace> Man I’m really getting into silly question territory now
06:02 PM lcnc-relay: <roguish> usually 1 psu. I have 1 large toroidal type
06:08 PM lcnc-relay: <roguish> https://jauriarts.org/_heisenbridge/media/matrix.org/ypjMZuCYNyGIDXKxhPcFjSIz/wYQN76RKHXE/image.png
06:09 PM lcnc-relay: <Mister Wallace> Chunky
06:09 PM lcnc-relay: <roguish> ya don't want one too smalll. better bigger
06:10 PM lcnc-relay: <Mister Wallace> Definitely
06:11 PM lcnc-relay: <pink_vampire@> roguish: how did you upload the picture here?
06:12 PM xxcoder: wallace is on matrix
06:12 PM xxcoder: I am thinking about allowing image to be embedded, but warn people not to add text to same post as image to prevent echo links
06:13 PM lcnc-relay: <roguish> pink_vampire@: copy / paste
06:13 PM lcnc-relay: <roguish> directly to the line
06:14 PM xxcoder: roguish not on discord
06:14 PM lcnc-relay: <roguish> matrix
06:15 PM xxcoder: yeah and pinks on discord :)
06:22 PM lcnc-relay: <.le_potato@> xxcoder right
06:23 PM lcnc-relay: <.le_potato@> xxcoder: without dust collector its 20$, with it 140$
06:23 PM lcnc-relay: <.le_potato@> from shop
06:23 PM roycroft: i just found out that there's a new fire right outside town, on the other side of the road from the one that just got put out
06:23 PM lcnc-relay: <.le_potato@> 20mins milling...
06:24 PM lcnc-relay: <.le_potato@> i did try to mill with 3mm tool
06:24 PM lcnc-relay: <.le_potato@> its broke as soon reached the disc, lol
06:25 PM lcnc-relay: <.le_potato@> but 5mm ball is perfect
06:25 PM xxcoder: so its for dust and not cooling? I thought it was both dust collect and cooling.
06:25 PM roycroft: it's not on the maps yet, but the ups driver was telling me about it, and there are non-stop sirens right now
06:30 PM lcnc-relay: <xxcoder@> https://jauriarts.org/_heisenbridge/media/jauriarts.org/JqCCaJMhHcGmNlRUOnWtVzKe/F8aTYSu1QAI/image.png
06:30 PM xxcoder: oops. was testing and pasted into wrong channel
06:38 PM xxcoder: yep can paste image, but if its enabled, url to image is pasted, it will double up in irc
06:38 PM xxcoder: still broken in that sense.
06:45 PM lcnc-relay: <.le_potato@> Tom_L: can you please explain how tool offset meter works?
07:10 PM lcnc-relay: <pink_vampire@> What do you use now for CAM?
07:14 PM Tom_L: le_potato, you mean G54..G59 offsets?
07:17 PM Tom_L: http://linuxcnc.org/docs/stable/html/gcode/g-code.html#gcode:g10-l2
07:19 PM Tom_L: http://linuxcnc.org/docs/stable/html/gcode/g-code.html#gcode:g54-g59.3
07:19 PM Tom_L: the variable numbers associated with the offsets
07:31 PM Tom_L: for tool length offset it reads the Z from the tool table with the H word and G43
07:31 PM Tom_L: http://linuxcnc.org/docs/stable/html/gcode/g-code.html#gcode:g43
07:40 PM lcnc-relay: <skunkworks8841@> lol - I just found a 2nd sterrit 12 inch digital caliper.. brand new in box.
07:47 PM lcnc-relay: <skunkworks8841@> wonder if it is real
07:47 PM Tom_L: check the battery for leakage
07:48 PM lcnc-relay: <skunkworks8841@> just did. It was dead - put a new one in it. it feels - kinda cheap.
07:48 PM Tom_L: heh
07:48 PM Tom_L: i like mitsutoyo
07:49 PM lcnc-relay: <skunkworks8841@> I do too.. Dad got 2 from the pawn shop. Those are the 2 I use when I am actually wanting to be accurate.
07:49 PM Tom_L: i have a couple HF ones i use to scribe stuff
07:49 PM lcnc-relay: <skunkworks8841@> yep
07:49 PM Tom_L: and a good mitsu 1" mic
07:49 PM lcnc-relay: <skunkworks8841@> he has another real starrett 12 inch which is nice..
07:49 PM Tom_L: i have 6 & 8" no 12
07:50 PM Tom_L: https://www.transcat.com/64pka076b-223386
07:51 PM Tom_L: have that set
07:51 PM Tom_L: 2x
07:51 PM Tom_L: kid has one
07:51 PM Tom_L: milled a pocket for a 1" gage
07:52 PM Tom_L: starrett are priced like snapon :)
07:53 PM lcnc-relay: <skunkworks8841@> we have a zero to 1 inch digital too... I could not tell you were it is currently though
07:53 PM lcnc-relay: <skunkworks8841@> boy - sure some random stuff around here
07:54 PM Tom_L: i await to hear the latest find :)
07:54 PM lcnc-relay: <skunkworks8841@> https://photos.app.goo.gl/1kfTFccXcbzQW1vg7
07:54 PM lcnc-relay: <skunkworks8841@> quinn?
07:54 PM Tom_L: no idea
07:54 PM Tom_L: absolute so not terrible
07:55 PM Tom_L: i have a similar general? depth mic
07:59 PM lcnc-relay: <skunkworks8841@> there is a lot of old school stuff here. hmm - still don't know where the digital 1 inch is
08:00 PM lcnc-relay: <skunkworks8841@> found it. it is a no-name. remember it working well though
08:01 PM Tom_L: got one with the 'odometer' number display
08:01 PM Tom_L: and one plain one
08:01 PM Tom_L: i think the 'odometer' one was a blue point one of the boys got during vo'tech
08:03 PM Tom_L: https://www.ebay.com/itm/376471747524
08:03 PM Tom_L: similar
08:04 PM lcnc-relay: <skunkworks8841@> I have seen those.. I think they have one at work
08:05 PM lcnc-relay: <skunkworks8841@> lol - digital
08:05 PM Tom_L: did he have any hole air gages?
08:05 PM Tom_L: my bud has one of those
08:05 PM Tom_L: very accurate
08:05 PM lcnc-relay: <skunkworks8841@> As I don't know what that is... I would guess no...
08:06 PM xxcoder: its pretty amazing measuing tool
08:06 PM Tom_L: calibrated air escapement from a hole plug
08:06 PM lcnc-relay: <skunkworks8841@> he never got into gauge blocks and what are they called? pins?
08:06 PM roycroft: gauge pins
08:06 PM lcnc-relay: <skunkworks8841@> right@
08:06 PM lcnc-relay: <skunkworks8841@> !
08:06 PM lcnc-relay: <skunkworks8841@> although - I think I would like to have a set
08:06 PM lcnc-relay: <skunkworks8841@> of both
08:06 PM Tom_L: this uses air
08:06 PM Tom_L: and has a dial indicating loss
08:07 PM Tom_L: alot more precise than hard gages
08:07 PM lcnc-relay: <skunkworks8841@> we have a ton of go-no go gauges that come in handy - they were from a local machine shop. we don't have every size - but we have a ton..
08:07 PM Tom_L: i forget what they're called
08:07 PM lcnc-relay: <skunkworks8841@> huh - cool
08:09 PM Tom_L: you're supposed to have a plug for each size hole but you can fudge a bit with the dial
08:12 PM Tom_L: https://kerleycorp.com/airgages/
08:12 PM Tom_L: that may be it but his was different
08:14 PM Tom_L: a whole 'thing' about them https://www.gagesite.com/documents/Metrology%20Toolbox/Air%20Gaging.PDF
08:16 PM Tom_L: some will measure to a
08:16 PM Tom_L: resolution of 5 millionths.
08:19 PM Tom_L: there are gage pins and blocks both round and square
08:20 PM Tom_L: cmm have taken the place of alot of measuring equipment
08:23 PM Tom_L: if a shop had a set of gage pin/blocks they would be required to be recertified every so often
08:28 PM Tom_L: https://westportcorp.com/pages/air-gages-for-internal-diameters-1
08:31 PM roycroft: i have a shop
08:31 PM roycroft: i have a set of gage blocks
08:31 PM roycroft: i have never had them recertified
08:31 PM Tom_L: :)
08:32 PM roycroft: and i've had them way longer than so often
08:32 PM Tom_L: you don't make parts for aero or space
08:32 PM roycroft: i do not
08:33 PM Tom_L: i learned a 'fun fact' about apache... the finished copter must weigh in within 20 lbs of spec so their parts are alot closer tolerance
08:33 PM Tom_L: my kid made floors for them for a while
08:33 PM xxcoder: so did shop I worked for
08:34 PM xxcoder: most penis-like part I ever made, was for helicoper too
08:35 PM lfluffywof: a lot of my stuff has calibration stickers on it from the '80s...
08:37 PM lfluffywof: I think my surface plate says '68 or something like that. :P
08:43 PM lcnc-relay: <.le_potato@> Tom_L: I mean use tool offset switch thing
08:43 PM lcnc-relay: <.le_potato@> that i bought from ali
08:44 PM Tom_L: i don't use one
08:44 PM lcnc-relay: <.le_potato@> oh
08:44 PM lcnc-relay: <.le_potato@> how do you know the lenght then?
08:44 PM lcnc-relay: <.le_potato@> how far is your tool from the material?
08:44 PM Tom_L: you would touch off the top and calculate it's height in relation to your work zero
08:45 PM Tom_L: i set my cad cam up usually 1" above the work and use a 1" gage to set the tools
08:45 PM lcnc-relay: <.le_potato@> but how you set your tool offset 🥲
08:45 PM Tom_L: jog down to the gage and zero it out
08:46 PM lcnc-relay: <.le_potato@> ah
08:46 PM lcnc-relay: <.le_potato@> thats so manual
08:46 PM Tom_L: then you use one tool as a reference to the work zero
08:46 PM Tom_L: i'm used to it
08:46 PM lcnc-relay: <.le_potato@> i have that tool offset switch thing
08:46 PM Tom_L: there are plenty using tool touch off but i'm not one
08:46 PM Tom_L: i know
08:46 PM lcnc-relay: <.le_potato@> why not
08:47 PM Tom_L: i'm used to it
08:47 PM lcnc-relay: <.le_potato@> and?
08:47 PM Tom_L: jt uses a round pin
08:47 PM Tom_L: like a feeler gage under the tool
08:48 PM lcnc-relay: <.le_potato@> but why not automatic
08:48 PM Tom_L: but i have holders and set all my tools prior to running the job
08:48 PM lcnc-relay: <.le_potato@> oh
08:48 PM Tom_L: so i just change to the next one
08:48 PM lcnc-relay: <.le_potato@> do you have something quickchange?
08:49 PM Tom_L: you use collets you can't do that
08:49 PM lcnc-relay: <.le_potato@> yes 🙁
08:49 PM Tom_L: not really quick but yes
08:49 PM lcnc-relay: <.le_potato@> how is it called that you have?
08:50 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/cutters/Tool_Holder2.jpg
08:50 PM lcnc-relay: <.le_potato@> oh
08:50 PM Tom_L: most larger machines use tapered holders
08:50 PM lcnc-relay: <.le_potato@> yes
08:50 PM Tom_L: like cat 40 or 50
08:50 PM lcnc-relay: <.le_potato@> can i do that with my spindle?
08:51 PM Tom_L: no idea
08:52 PM Tom_L: they preset the tools and keep them in the carousel until called up
08:52 PM lcnc-relay: <.le_potato@> i did try to mill that brake disc with 3mm tool, as soon its touched the disc, its broke
08:52 PM Tom_L: my tool list in linuxcnc tool table matches my cad cam so i know what tool is what
08:52 PM Tom_L: maybe you plunged too fast
08:53 PM Tom_L: plunge cuts should be 1/2 to 1/3 normal feed
08:53 PM lcnc-relay: <.le_potato@> 30mm/min
08:54 PM Tom_L: 1.18 ipm is pretty sloe
08:54 PM Tom_L: slow
08:54 PM lcnc-relay: <.le_potato@> i know
08:54 PM lcnc-relay: <.le_potato@> and broke
08:54 PM Tom_L: pretty small cutter
08:55 PM Tom_L: requires more care in feed / speed selection
08:55 PM lcnc-relay: <.le_potato@> i need an rpm counter
08:55 PM lcnc-relay: <.le_potato@> i have no clue about my rpm when milling steel
08:56 PM Tom_L: chip loads with that small cutter would be much less than a larger cutter
08:56 PM Tom_L: .0005 ipt maybe
08:57 PM Tom_L: .01 mm/t
08:57 PM lcnc-relay: <.le_potato@> thats nothing
08:57 PM Tom_L: per rev per tooth
08:57 PM Tom_L: chip load
08:57 PM Tom_L: not feed
08:57 PM lcnc-relay: <.le_potato@> thats how i milled
08:57 PM Tom_L: amount of material removed per tooth per revolution
08:59 PM Tom_L: i'm guessing on those numbers
08:59 PM lcnc-relay: <.le_potato@> was 0.05 on tool
08:59 PM lcnc-relay: <.le_potato@> so you guessed good
09:01 PM Tom_L: with a high speed spindle you may struggle to cut steel
09:01 PM lcnc-relay: <.le_potato@> its about 1-2k
09:01 PM Tom_L: that's not much
09:01 PM lcnc-relay: <.le_potato@> thats good with 400mm/sec
09:02 PM Tom_L: mine tops out at 5500 but i wanted lower end torque over speed
09:02 PM lcnc-relay: <.le_potato@> i cant go faster because my spindle have no torque
09:02 PM lcnc-relay: <.le_potato@> my spindle rated to 18k
09:02 PM Tom_L: not mine
09:02 PM Tom_L: i did that on purpose
09:02 PM lcnc-relay: <.le_potato@> the stock one was with gearbox and 8kw
09:02 PM Tom_L: great for aluminum and softer materials
09:02 PM lcnc-relay: <.le_potato@> max speed 2800
09:05 PM lcnc-relay: <.le_potato@> tomorrow i mill with flexgui!
09:05 PM Tom_L: there are a few changes that have yet to be pushed but i'd still get the latest deb
09:05 PM lcnc-relay: <.le_potato@> like what?
09:06 PM Tom_L: https://github.com/tlight9/flexgui/compare/master...jethornton%3Aflexgui%3Amaster
09:06 PM Tom_L: ones i haven't built debs for yet
09:07 PM Tom_L: nothing major
09:07 PM lcnc-relay: <.le_potato@> how i use the 3d touch sensor?
09:07 PM Tom_L: added an ini setting for keyboard jogging
09:07 PM lcnc-relay: <.le_potato@> need any parameters
09:07 PM lcnc-relay: <.le_potato@> or just press X->
09:07 PM Tom_L: there is a whole page of parameters to set
09:07 PM lcnc-relay: <.le_potato@> and it i will do it?
09:08 PM lcnc-relay: <.le_potato@> ohhhhhhh
09:08 PM lcnc-relay: <.le_potato@> inside flexgui?
09:08 PM Tom_L: they are configured for inch in the example
09:08 PM Tom_L: i'll take a screen shot of them...
09:09 PM lcnc-relay: <.le_potato@> where i have to set it up?
09:09 PM lcnc-relay: <.le_potato@> can i use it manually?
09:10 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/touch-probe3-probe-settings.png
09:10 PM Tom_L: those are all inch
09:10 PM * lfluffywof pays attention, because wants to get a touch probe to automagically find edges and rotation of stock
09:11 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/touch-probe3-2.png
09:11 PM Tom_L: lfluffywof, ^^
09:11 PM Tom_L: i have a yt of the rotated stock one
09:11 PM lfluffywof is now known as fluffywolf
09:12 PM fluffywolf: I also want to do height mapping for pcb milling... all the fun things a probe can do!
09:12 PM Tom_L: https://www.youtube.com/watch?v=W8hpXoHmHzk
09:12 PM lcnc-relay: <.le_potato@> i have to learn it tomorrow
09:13 PM * fluffywolf pauses davidxnewton's ramp playthoughs to watch
09:13 PM Tom_L: it is an example, you can modify it to suit your own needs
09:14 PM Tom_L: i tried for a while to maintain a metric version but it got too confusing keeping track of everything
09:14 PM Tom_L: i think i left the metric files in the example but they may not be fully up to date
09:15 PM * fluffywolf checks tom's other videos
09:16 PM fluffywolf: 150ipm... I don't remember what I have my rapids set to. somewhere around there.
09:16 PM lcnc-relay: <.le_potato@> on GUI is on metric
09:16 PM Tom_L: my rapids are 210
09:16 PM lcnc-relay: <.le_potato@> or imperial
09:16 PM lcnc-relay: <.le_potato@> or unit
09:16 PM Tom_L: imperial
09:16 PM lcnc-relay: <.le_potato@> nooo
09:16 PM Tom_L: fix it :)
09:17 PM lcnc-relay: <.le_potato@> first i just convert the value
09:17 PM fluffywolf: just glancing at your axis test videos. heh.
09:17 PM Tom_L: angles should be the same
09:17 PM Tom_L: that's about it
09:17 PM Tom_L: fluffywolf, i was testing some cutters
09:18 PM roycroft: https://roycroft.us/Shop/ShopEntryDoor.jpeg
09:18 PM roycroft: there's my first go at the shop door design
09:18 PM roycroft: no details yet like fillets and the inlays
09:18 PM lcnc-relay: <.le_potato@> freedome values
09:18 PM roycroft: but that's the basic shape
09:18 PM roycroft: there will be an identical pair of them
09:18 PM lcnc-relay: <.le_potato@> at least you dont use fahrenheit for angle
09:19 PM roycroft: giving me a 72"/1830mm wide opening
09:19 PM xxcoder: interesting slopes
09:20 PM roycroft: the openings will have stained glass inserts
09:20 PM fluffywolf: I have a 4x8 router table, but it's nowhere near functional... never thought of making doors with it. lol
09:21 PM roycroft: i'll be refining that design before i build the doors, but i'm pleased with the proportions overall, so i can set my opening size in stone now
09:21 PM fluffywolf: I find the asymetrical window heights... disturbing.
09:22 PM roycroft: it's intentional
09:22 PM roycroft: and it will look better when the mullions have an edge treatment and the stained glass lights are installed
09:22 PM fluffywolf: do you really want to cut those shapes into the door, or cut a square opening then make thin strips in the patterns, so you can use a single square glass pane?
09:22 PM roycroft: the upright mullions are tapered, btw - that's not just a perspective thing
09:22 PM roycroft: i will cut the lights to fit the openings
09:23 PM roycroft: and there will be six lights
09:23 PM roycroft: these are going to be high end doors
09:23 PM roycroft: if i made them for a customer i would charge many thousands of dollars for them
09:23 PM roycroft: i'm not taking shortcuts
09:24 PM fluffywolf: FOUR. FOUR LIGHTS.
09:24 PM roycroft: THERE ARE SIX LIGHTS
09:24 PM fluffywolf: lol
09:24 PM * roycroft just watched that episode a couple months ago
09:24 PM fluffywolf: I can add "make doors" to the list of things I could do with my router table if it wasn't a piece of crap.
09:25 PM fluffywolf: I haven't seen any star trek in many years.
09:25 PM fluffywolf: but that's still the first thing that came to mind when you said six lights. lol
09:27 PM fluffywolf: I got someone else's router project cheap on craigslist. some parts of it are nice, like the 5x10 steel frame. other parts... I don't think there's enough drugs in the world to explain some parts of the design.
09:28 PM fluffywolf: I need to completely re-design the X axis, both the linear guides and the drive.
09:33 PM Tom_L: ahh, that 150ipm one was trying to get a following error fault
09:33 PM Tom_L: running all axis in all quadrants
09:34 PM fluffywolf: your videos could do with some narration. lol
09:34 PM Tom_L: i don't do them for fancy, just to get an idea across
09:34 PM Tom_L: i put 0 time in them to speak of
09:36 PM Tom_L: https://www.youtube.com/watch?v=trzO8H6tKW8
09:36 PM Tom_L: that was the cutter test one
09:37 PM Tom_L: F35 worked but F30 was better
09:39 PM fluffywolf: that sounded like a nice cut.
09:39 PM fluffywolf: my biggest machine now is my lathe/mill combo, and it has neither the power nor rigidity for a cut like that.
11:05 PM roycroft: hmm, so i went out to try to do a little work on the minirouter
11:06 PM roycroft: i discovered that i did not shut it down last night
11:06 PM roycroft: so it had been turned on for about 30 hours or so
11:06 PM roycroft: i tried homing it, but the motors did not work at all
11:06 PM roycroft: and i could move the axes by hand
11:07 PM xxcoder: anything hot?
11:07 PM roycroft: the drivers still had the power lights on, which has not been the case when they stopped in mid-emovement
11:07 PM roycroft: no, nothing was hot
11:07 PM roycroft: and even z did not work
11:07 PM roycroft: i power cycled the drivers and restarted linuxcnc and all was well
11:07 PM xxcoder: weird
11:07 PM roycroft: yes
11:07 PM roycroft: it's disturbing
11:07 PM roycroft: i mean, i don't plan on running 30 hour jobs on the thing
11:08 PM roycroft: but it should have remained functional after just idling for that long
11:08 PM fluffywolf: could have gotten hot, then shut down, and now was cold because shut down...
11:08 PM roycroft: possibly
11:08 PM fluffywolf: check temps after a half hour or something
11:08 PM roycroft: i should have shut it down
11:08 PM roycroft: yeah
11:08 PM roycroft: it's turned off now
11:09 PM roycroft: but i'll do that the next time i have some time to work on it
11:09 PM roycroft: it's too late now to do anything more
11:11 PM xxcoder: you got a heat camera?
11:12 PM roycroft: i hope i don't end up having to swap in my gecko drivers for the tb6600s
11:12 PM roycroft: i have an ir thermometer
11:12 PM roycroft: but not an ir camera
11:12 PM fluffywolf: I found my lathe/mill combo overheats after about 30-45 minutes... need to add more heatsinking to the drivers.
11:12 PM xxcoder: infiray p2 is pretty cheap, but plenty
11:12 PM roycroft: i've actually been meaning to get one
11:12 PM xxcoder: of course theres flickr which is top line
11:12 PM roycroft: it will come in useful as i remodel my house
11:12 PM fluffywolf: I'm running 8A at 65V to the steppers, so the drivers have some work to do.
11:13 PM roycroft: i can look for heat leaks in the floors and walls and ceiling
11:13 PM fluffywolf: I have an old flir i3 that I upgraded to an i7. it lacks features like a visual camera for overlays and such, but it gets the job done.
11:13 PM roycroft: flir is pricey, iirc
11:14 PM xxcoder: er I meant flir but yeah it is. thats why I got p2
11:14 PM fluffywolf: yes, which is why I have an old, base feature model. lol
11:15 PM xxcoder: $250 for p2 pro now. I remember getting it for bit less
11:16 PM xxcoder: one postive on p2 is it doesnt use battery, flir one have its own battery
11:17 PM xxcoder: p2 uses phone battery but you will never find out your p2 ran out of battery.
11:18 PM fluffywolf: you find uses for one when you have one... https://imgur.com/a/yp48HsC for example, how full is your kerosene tank? lol
11:18 PM xxcoder: lol nice
11:19 PM roycroft: maybe you'll rent me your camera, xxcoder
11:19 PM roycroft: i really only need one for a week
11:20 PM roycroft: actually, i probably need one for a week, and then for an hour or so at a time periodically
11:20 PM roycroft: so i should probably purchase one
11:21 PM xxcoder: sure $50 a day ;)
11:21 PM roycroft: the thing is, my heat pump is pretty efficient, and my energy bills already low, so it might take me a long time to make up $250 in energy savings by sealing up the house better
11:22 PM fluffywolf: I watched ebay until I saw this one cheap. it's the i3 model, which was their crappiest offering... but the i3, i5, and i7 are all the exact same hardware. the i7 gives you the full resolution, full accuracy image. the i5 shrinks the image. the i3 shrinks the image more, then adds random noise. yes, the difference is the cheaper models have software that intentionally degrades the images.
11:22 PM xxcoder: well you could use it on mini router. video of it idling
11:22 PM roycroft: but it would be interesting to look at heat maps of machines and the like
11:22 PM xxcoder: see what happens, and when it pops off
11:22 PM fluffywolf: fortunately, individuals on various websites have written tools to let you tell the i3 it's now an i7....
11:23 PM xxcoder: wolf is there any rootkit for upgrading those?
11:23 PM xxcoder: lol ok
11:23 PM fluffywolf: so I have one that says i3, but takes i7 images. heh.
11:24 PM roycroft: there's a flir 1 gen 3 for iphone on ebay for $120 right now
11:24 PM roycroft: would that be useful/upgradable?
11:24 PM roycroft: there's an i5 for $350
11:25 PM fluffywolf: the i series is very obsolete, and I wouldn't recommend anyone purchase one now, unless really cheap.
11:25 PM fluffywolf: all the newer models have a visual camera in addition to the ir camera, and do overlays that make it a lot easier to see what you're looking at.
11:26 PM xxcoder: p2 isnt that fancy but it have been plenty for me.
11:26 PM xxcoder: it have point, square area of temps, max min and average
11:26 PM xxcoder: skies always show as "infinitely cold" btw
11:26 PM roycroft: yeah, if i had an ir-only one i'd have to do something like make a 2 camera holder and mount the ir camera and a gopro right next to each other and use them together
11:26 PM xxcoder: hmm curious about clouds a sec
11:27 PM roycroft: i wonder what it thinks of the sky when the aqi is 190
11:27 PM fluffywolf: space is cold. :P
11:27 PM xxcoder: techinically yes, but prically saying, no.
11:28 PM * fluffywolf finishes watching davidxnewton's first ramp2025 video, contemplates bed, decides not quite yet
11:30 PM xxcoder: learned something cool
11:30 PM xxcoder: clouds look so cool in heat camera.
11:33 PM roycroft: $100 is a no-brainer for a thermal camera
11:33 PM roycroft: but you can't really get one that's useful for that price
11:33 PM roycroft: $250 is a point where i need to think about it for a while
11:33 PM xxcoder: yeah if you want actually good ones p2 is in that range
11:33 PM xxcoder: ebay have one for $200
11:34 PM roycroft: $500 is a wait until i really need one badly price
11:37 PM xxcoder: https://imgur.com/a/Ple8nR4
11:37 PM xxcoder: 3 images of skies
11:37 PM xxcoder: theres plane in one lol
11:39 PM fluffywolf: which is, in fact, why it's so hard to get high-resolution high-speed ir cameras.
11:39 PM fluffywolf: (planes)
11:41 PM xxcoder: anyway roy those images probably can gve you idea on what p2 can do
11:46 PM fluffywolf: (I probably should add an explanation to that... the government doesn't want people making heat-seeking missiles from off-the-shelf parts, so adds restrictions to IR camera capabilities. the restrictions only apply to exports, but consumer models usually follow them too)
11:47 PM xxcoder: yeah. thats why I waited years before finally getting p2.
11:48 PM xxcoder: I didnt want 9.5x9.5 pixel camera :P
11:48 PM fluffywolf: lol
11:49 PM fluffywolf: I remember looking at cheap chinese ones a while back, and realizing they were 30x30.
11:50 PM fluffywolf: mine is 120x120, which is still low, but that's 16 times the pixels of the chinese one. heh.
11:50 PM xxcoder: 256x192 for p2. not quite as good as flir
11:51 PM roycroft: there's one made by perfect prime for $150
11:51 PM roycroft: that's beyond no brainer but not up to think about it for a while
11:51 PM fluffywolf: bbl, wolfy bedtime
11:51 PM roycroft: ciaoder
11:52 PM xxcoder: perfect seem to have small lineup of phone camera attachment.
11:52 PM xxcoder: $100 cheaper
11:52 PM roycroft: i'm starting to look at their stuff now
11:52 PM xxcoder: 80x60 pixels resolution
11:52 PM xxcoder: not quite as good as p2, but might be plenty
11:53 PM xxcoder: other one is 32x32
11:54 PM xxcoder: ir501 is 206 x 156
11:55 PM roycroft: looks like they only sell direct, and they're sold out of the iphone version
11:56 PM roycroft: i do not need one that i can easily use all day long, like home inspectors and the like do
11:56 PM roycroft: the quality needs to be decent
11:56 PM roycroft: but it doesn't have to be a super tough, stand-alone point and shoot thing
11:57 PM roycroft: a dongle that i plug into an iphone or ipad and manage with an app would be fine
11:57 PM xxcoder: yeah. its been plenty for me
11:58 PM xxcoder: seems infiray is now Thermal Master
