12:00 AM travis_farmer: i think my mother does something with it every month or so. maybe she is running the cleaning...
12:10 AM travis_farmer: she uses ice pretty regularly... has ice in her nightly bottle of wine...
12:10 AM XXCoder: cool
12:39 AM ithe2guu[m]: what is the most common way to set up tool table? i am defining my spindle nose as zero and listing all my tools as postive offsets from that point
12:40 AM ithe2guu[m]: this does not seem to be working
12:40 AM XXCoder: I always pick a common point
12:40 AM voldial: Hi. Does anyone know where to find a enco 100-1527 mill manual? I found paper copy's for sale: https://ozarktoolmanuals.com/machinemanual/enco-milling-machine-instructions-operators-parts-manual/
12:40 AM XXCoder: set part coord reference from that, and use it for tool lengths
12:41 AM XXCoder: that way you can change tools without losing your reference point
12:41 AM voldial: no luck here: https://www.hobby-machinist.com/resources/categories/enco.530/
12:42 AM XXCoder: ithe2guu[m]: when I worked, most common reference was top of 123 block (3" height off table)
12:42 AM ithe2guu[m]: with how i have all my tools set up as postive offsets, after i do a tool change, it does not go down to where is should go
12:43 AM ithe2guu[m]: sure, but that does not answer my question. what is that refferencing off of?
12:44 AM XXCoder: its way to set part coord and tool lengths
12:45 AM XXCoder: other way we did at job was "cone reference" where theres metal block with cone in it, put say cat30 with tool on it, measure top of block then rise to end of tool. that is the length for tool. for parts you would use known length tool to touch down then subtract number of length to get part z.
12:45 AM voldial: ah. found it.
12:45 AM XXCoder: voldial: hopefully someone will know
12:45 AM XXCoder: oh nice
12:45 AM voldial: XXCoder: :) https://www.hobby-machinist.com/attachments/enco_mill-pdf.364536/
12:46 AM XXCoder: ithe2guu[m]: with your scheme it should work, but what does you use to find part z?
12:47 AM ithe2guu[m]: i used a pice of shim stock and a 123 block
12:47 AM ithe2guu[m]: to find my offsets
12:48 AM XXCoder: then you subtracted the 123block, shim, and tool length?
12:48 AM ithe2guu[m]: i do not understand why it is now doing what it should do
12:48 AM ithe2guu[m]: no, i am defining the nose of my spindle as zero
12:48 AM XXCoder: ok try to list setup you do, supposing you have no tools yet, and part is not set and you want to start setup
12:48 AM ithe2guu[m]: and anything past that is a postive offset
12:49 AM XXCoder: *setup steps
12:49 AM ithe2guu[m]: i am using tormach tts
12:49 AM ithe2guu[m]: so i am inputing the lenght
12:49 AM XXCoder: how do you find the length?
12:50 AM ithe2guu[m]: why does that mater
12:50 AM roycroft: when i ever get my mill conversion done i plan on using tts for it
12:50 AM XXCoder: it does matter, I listed in least 3 methods to do it, all would have different length numbers and valid if part setup was matching
12:51 AM ithe2guu[m]: i fined the lenght of the tts tool
12:51 AM ithe2guu[m]: like how they do on the tormach machines
12:51 AM XXCoder: https://tormach.com/tts-cnc-operator-set-with-tool-assist-32284.html
12:51 AM XXCoder: this?
12:51 AM ithe2guu[m]: with the surface plate and calipers, or with a 123 block
12:52 AM XXCoder: ok so you set tools off the common reference, the surface plate with caliper
12:52 AM ithe2guu[m]: all my offssets are pstive from the zero point ( the spindle nose)
12:52 AM ithe2guu[m]: yeah
12:52 AM XXCoder: so part z should use that same reference point, the spindle nose
12:53 AM XXCoder: and you have known length, one of tools length
12:53 AM XXCoder: how do you use those to find part z?
12:53 AM XXCoder: note im trying to understand your process
12:54 AM ithe2guu[m]: the problem i am having is when doing a tool change, it does not go to the correct off set
12:54 AM XXCoder: double checking, you have had set each tool its own lengths?>
12:55 AM XXCoder: and that gcode calls for correct erm whats that gcode again? g43? h(toolnumber)
12:55 AM XXCoder: wow I actually remembered right. g43 is indeed tool length offset
12:55 AM ithe2guu[m]: like one tool has a postive offset of 78mm, then the next one has a lenght of 85mm, and when that tool change happens, it starts running at a verry large z hight like 100mm above the work peice
12:56 AM XXCoder: odd
12:57 AM XXCoder: double check your tool length for second tool
12:57 AM XXCoder: and that in gcode, H is for correct tool
12:57 AM XXCoder: ie for tool 2, H2
12:58 AM XXCoder: or H02, some machines require a zero
01:03 AM ithe2guu[m]: is the lenght offset in hsm works reliven to after i post it?
01:03 AM * ithe2guu[m] uploaded an image: (602KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/cEXAHxLabExWYTRaVxIRxvvP/image.png >
01:03 AM ithe2guu[m]: like i have the lenght of this tool set to 6mm
01:03 AM ithe2guu[m]: witch is not correct
01:03 AM ithe2guu[m]: but i dont think that is relivent
01:04 AM XXCoder: im not familiar with solidworks
01:04 AM XXCoder: no im talking about tool lengths in your cnc machine not cam
01:04 AM ithe2guu[m]: those should be correct
01:05 AM XXCoder: id suggest double check
01:05 AM XXCoder: its just stage to troubleshoot where it come from
01:05 AM travis_farmer: if your CAM tool lengths match the ones stored in LinuxCNC... i would think...
01:06 AM ithe2guu[m]: so you are saying that the tool lenght offset in my cam is relivent?
01:09 AM travis_farmer: i don't think, and correct me if i am wrong, but i don't think CAM sends the tool length database to LinuxCNC. LinuxCNC has it's own database.
01:10 AM travis_farmer: maybe i am off-base, and confusing the issue...
01:11 AM ithe2guu[m]: so, no it is not relevant
01:11 AM XXCoder: did you write down the tool lengths on paper?
01:12 AM ithe2guu[m]: yeah
01:12 AM XXCoder: if so, can you compare em with your input into tomach tool lengths
01:12 AM ithe2guu[m]: i will do more investagtion tomrrow
01:13 AM XXCoder: no problem. have good day/night
01:17 AM travis_farmer: hmmm, i think i was sleep shopping on eBay yesterday... i seem to have acquired this on my eBay purchase list, and i have no memory of buying it... https://www.ebay.com/itm/374589840948
01:17 AM XXCoder: check address on your buy
01:17 AM XXCoder: see if its your home
01:18 AM travis_farmer: yeah, it is being shipped to my address
01:18 AM XXCoder: 10w interesting
01:20 AM XXCoder: if it comes with free green goggles throw it away and get good one
01:21 AM travis_farmer: what's wrong with the green ones?
01:21 AM XXCoder: its protection peak is almost certainly wrong
01:21 AM travis_farmer: ok, good to know
01:21 AM XXCoder: it does protect some but not that good.
01:21 AM XXCoder: for blue laser it should be yellowish goggle
01:24 AM travis_farmer: https://www.ebay.com/itm/143736101408 too bad these are from China...
01:25 AM XXCoder: https://www.amazon.com/gp/product/B07DCRR8NG/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
01:25 AM XXCoder: one I got
01:26 AM travis_farmer: do they fit over glasses?
01:26 AM XXCoder: yeah
01:26 AM XXCoder: seems frame breaking apart is common
01:26 AM XXCoder: mine may be older version
01:34 AM Deejay: moin
01:34 AM roycroft: laser eye protection that works will have the wavelength range it absorbs and the optical density marked right on the glasses
01:34 AM roycroft: if yours doesn't have that then toss them and get real ones :)
01:35 AM Deejay: protect the remaining eye!
01:35 AM travis_farmer: yeah, i have some crappy green ones from my first laser cnc... already tossed them :-)
03:24 AM travis-farmer is now known as travis_farmer
04:03 AM travis_farmer: Hmmm, just realized, i have a whole pile of 12V SPDT cube (automotive) relays. i will have to test the coil current draw, but if i lower the field voltage of my 7i72 to 12V (rather than 24V), i can drive the relays i have (with flyback diodes added), and no need to buy a bunch of 24V relays...
04:46 AM JT-Cave: morning
04:48 AM JT-Cave: when the dream gets unsolvable it's time to wake up
05:06 AM travis-farmer is now known as travis_farmer
05:38 AM JT-Cave: rooster just crowed
05:50 AM Tom_L: morning
06:35 AM JT-Cave: might have a bit of rain in a bit
06:45 AM travis_farmer: clear weather here, today :-) 56F high of 75F
07:55 AM * JT-Cave starts his chicken day
08:17 AM JT-Shop: just enough rain so far to settle the dust
08:20 AM JT-Shop: yippee the jaws for my #93A showed up and fit perfect.
08:32 AM _unreal_: sweet
08:33 AM _unreal_: JT-Shop, I am in love with the servos I just got out of a SAT.
08:33 AM _unreal_: trying to figure out how I want to use them.
08:33 AM _unreal_: nema 34
08:34 AM _unreal_: brushless on encoders but no matter, rated 24, 35watt and 3000 RPM. They drove the 3 major axis on a 150 lb satellite
08:34 AM _unreal_: on=no
08:34 AM _unreal_: rated 24v
09:55 AM Tom_L: learned what a 'frog bolt' was. https://masterbolt.com/industry-served-railroad
09:57 AM Tom_L: also didn't know that's what these were called https://en.wikipedia.org/wiki/Sex_bolt
09:57 AM _unreal_: I'm getting kind of excited. so one of these sats I just got...... the motor controller seems to be super useful to me. I'm not saying the others are not. the others just have a complicated setup with control logic. rather then straight signaling step/dir or PWM/dir
09:57 AM Tom_L: recently saw some of the junkers you work on :)
09:58 AM Tom_L: one had 2 helo pads
09:58 AM _unreal_: this one I believe has PWM/DIR but what is cool. this control board has 3x brushless servo drivers, and one stepper
09:58 AM _unreal_: ?
09:58 AM Tom_L: in miami
09:58 AM _unreal_: oh
09:58 AM * travis_farmer[m] knew what a frog bolt is... ;-)
09:59 AM _unreal_: I'm having dreams of using this motor driver board and the 3 nema34 brushless motors on a large 3d printer
09:59 AM _unreal_: maybe modeled after the VZBOT
10:06 AM _unreal_: The other option would be a laser. I dont see my self using them on a cnc mill
10:07 AM _unreal_: would be nice but I just dont see it.
10:07 AM _unreal_: Its power is in its speed, and I dont think having to change directions real fast endlessly would be good for the drivers.
10:08 AM _unreal_: I would prob. want to be running it with a 5:1 belt ratio driving a ballscrew if I was to do that
10:08 AM _unreal_: maybe even 10:1
10:09 AM _unreal_: still 300 RPM
11:01 AM Guido2665[m]: Apologies, just after posting ingot sidetracked.
11:01 AM Guido2665[m]: Mixgeneric should have been muxgeneric; sth being something question still stands: assuming two different encoders (on mesa) with individual counts, what happens when i mux them to an axis?
12:04 PM ZincBoy[CAON][m]: What do you think will happen? What are you trying to accomplish? The general rule would be don't do that.
12:21 PM JT-Shop: light rain again here
12:26 PM Tom_L: cloudy but no rain yet
12:27 PM JT-Shop: got a guy coming to buy my 5' bushhog that I've not used in years
12:28 PM JT-Shop: found several laptops on fb markeplace for the laser
12:29 PM roguish[m]: Guido#2665: it might work. but i would not mux them. have a switch, either in hal, or physical. jogging does not keep track of position, it only used counts. it the input to the counting changes sources, it probably is ok. BUT TEST IT FIRST......
12:29 PM roguish[m]: also, run jogging in velocity mode.
12:32 PM Tom_L: i've got a whole pile of laptops..
12:33 PM JT-Shop: I've got a small pile of laptops
12:33 PM Tom_L: batteries are probably shot now
12:34 PM Tom_L: and surface pro
12:35 PM roguish[m]: recycle time....
12:38 PM JT-Shop: I just leave them plugged in when using them
12:38 PM Tom_L: same here
12:39 PM Tom_L: i have one really old one i take out to my buds when he has cnc problems
12:39 PM Tom_L: win 98?
12:39 PM Tom_L: takes a time or two to boot but it usually does
12:41 PM roguish[m]: i have an old win 95 laptop. still runs. i use it sometimes.....
12:42 PM Tom_L: yeah i updated mine from that to 98 SE
12:44 PM JT-Shop: my old laptop is xp iirc
12:45 PM Tom_L: i'm not sure what's on the 'newer' old ones
12:45 PM JT-Shop: i've got 7 on one and 10 on the other one
12:46 PM Tom_L: those more than likely have 8 on them
12:48 PM roguish[m]: i have finally migrated from 7 to 10........ needed some stuff that won't run on 7....
12:48 PM roguish[m]: this one i'm on here, now, is on 11. bought it at a recycle yard.....cheap. runs good.
12:48 PM * flyback bites travis_farmer853
12:55 PM Tom_L: flyback, you still up NE?
12:56 PM flyback: eh?
12:56 PM * flyback has been dealing with withdrawel for 2 days
12:56 PM flyback: skipped 2 medication dosages to save them for work this week
12:56 PM flyback: due to nationwide adderal shortage
12:56 PM flyback: and it sucks
12:57 PM flyback: oh north east
12:57 PM flyback: yeah I think so
12:57 PM flyback: if pennsylvania is north east
12:58 PM flyback: if you get a laptop with 7 or 8 you can still free upgrade to 10
12:58 PM flyback: then do a 11 upgrade if you want
12:58 PM flyback: I got a FISTA to free upgrade to 10
12:59 PM flyback: only cause it was released like one month before 7 was out
12:59 PM flyback: so it had a 7 compatible key
01:01 PM * JT-Shop will put linux on it
01:01 PM Tom_L: JT-Shop, all the laser stuff has linux versions?
01:02 PM flyback: im about to install promox on a 10w thin client and move irc to that
01:03 PM flyback: also got 2 servers work was throwing out
01:03 PM flyback: one is going to be either a proxmox or esxi server and the other is going to be a new data recovery project pc
01:05 PM JT-Shop: yup, no rpi though
01:05 PM Tom_L: oh?
01:05 PM JT-Shop: you just need lightburn for the laser
01:05 PM Tom_L: and it won't run on rpi?
01:05 PM flyback: rpi's are unobtainable right now
01:06 PM JT-Shop: roycroft, do you peel the blue film off the aluminum plate under the honeycomb?
01:06 PM JT-Shop: I have a box full
01:06 PM flyback: BMCC
01:06 PM * flyback hurls veegee at JT-Cave
01:06 PM JT-Shop: JT-Cave, is not here
01:07 PM * flyback hurls veeegee at JT-Shop
01:07 PM Tom_L: neither is veegee
01:07 PM * Tom_L slaps flyback with pepsi
01:07 PM * travis_farmer[m] wonders what is going on... :-)
01:07 PM Tom_L: flyback knows
01:08 PM flyback: <travis_farmer> Hmmm, just realized, i have a whole pile of 12V SPDT cube (automotive) relays. i will have to test the coil current draw, but if i lower the field voltage of my 7i72 to 12V (rather than 24V), i can drive the relays i have (with flyback diodes added), and no need to buy a bunch of 24V relays...
01:08 PM travis_farmer[m]: ???
01:09 PM flyback: you said flyback
01:09 PM flyback: heh
01:09 PM flyback: so I bit yuo
01:09 PM travis_farmer[m]: oh, lol
01:10 PM flyback: my boss had a pinball machine i tried to fix many yrs ago
01:10 PM flyback: looked like a bunch of the flyback diodes were bad
01:10 PM flyback: half the trannies had holes in them
01:11 PM travis_farmer[m]: yeah, gotta have the flybacks installed. :-)
01:11 PM travis_farmer[m]: ...and working
01:12 PM flyback: neat stuff
01:12 PM flyback: can't believe we have 8 cent arm chips now and 10 cent risc-v chips
01:13 PM travis_farmer[m]: i like the AVR chips, myself. though they aren't as powerful as those you mentioned...
01:13 PM flyback: avr isn't bad ;)
01:13 PM Tom_L: less register setup
01:15 PM * JT-Shop wonders what to put on the PC for lightburn?
01:15 PM flyback: lightburn?
01:15 PM travis_farmer[m]: i am a member of the DCC-EX (.com) team, and it is amazing what we are doing with Arduino boards :-)
01:15 PM Tom_L: flyback, laser software
01:15 PM flyback: ah neat
01:16 PM Tom_L: JT-Shop, says 64bit and suggests ubuntu
01:17 PM JT-Shop: going to test drive Fedora for some strange reason
01:17 PM travis_farmer[m]: why not winblows? ;-)
01:17 PM Tom_L: bullseye should work
01:17 PM JT-Shop: maybe I just don't like ubuntu anymore
01:17 PM JT-Shop: just putzing around
01:18 PM Tom_L: Ubuntu 20.04 or Fedora 36, anything else may not work as intended
01:18 PM * travis_farmer[m] can't wait to mount the laser on his cnc router... and fire up the death-ray ;-)
01:22 PM flyback: that's what vm's are for
01:22 PM flyback: heh
01:26 PM Guido2665[m]: With regard to the goal: one mpg on the pendant, one on the panel. Hence the need to switch between them. Thought of mux as a kind of switch.
01:27 PM roguish[m]: Guido#2665: ya gotta be sure only one feed pulses at a time
01:29 PM Guido2665[m]: That should be the easy part (hence hal)
01:30 PM Guido2665[m]: I’ll try to remember to report back;)
01:32 PM roguish[m]: be very careful. finger on the Estop
01:35 PM roycroft: mpgs are relative, not absolute - they won't keep track of position
01:35 PM roycroft: they'll just tell the controller how much to move along an axis
01:36 PM roycroft: what roguish said is the important thing
01:36 PM roycroft: have a switch that you can toggle to select the one you need at the moment
01:37 PM roycroft: if necessary, set up a 3-way switch system with a switch near each mpg
01:37 PM roycroft: so you can toggle it in either position
01:37 PM Guido2665[m]: Reading up on motion confirms this. I’ll try tonsure something up this week.
01:37 PM * flyback is setting up a bunch of vm's for legacy stuff and for one-off's and other such things
01:38 PM flyback: btw do you guys know about the ata resizing command for ide and sata disks
01:38 PM Guido2665[m]: Plan was to have a button on the panel. Either activate the pendant or not. Maybe dedicate a button on the pendant as well.
01:38 PM flyback: you can resize a disk down to a smaller size
01:38 PM flyback: so you don't have to find a old old disk because the system doesn't support large drives
01:39 PM roguish[m]: Guido#2665: figure some logic to swap them with one button or switch
01:40 PM Guido2665[m]: Plan is to use a Siemens 6fc 5103-0ad03-0aa0 panel with a SSerial adapter board https://github.com/Watze85/TWSSIO_V1.0_840C
01:40 PM Guido2665[m]: I had to smd solder that myself and I am not good at that. Still have some kinks to work out
01:41 PM Guido2665[m]: I was thinking momentary button + toggle + muxgeneric for all pendant related things. Muxgeneric used as it can handle int over float
01:55 PM zyp: can't you just add both encoders together instead of muxing between them?
01:56 PM ZincBoy[CAON][m]: Yes, I think that is a better solution. Avoids discontinuities.
02:08 PM mits5782[m]: Wow, I'm trying to use compensation.py and it's really broken once I start zooming in
02:08 PM * mits5782[m] uploaded an image: (8KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/iYSpmQwdeRCgwFtyPYkWxPHb/image.png >
02:09 PM mits5782[m]: that's a linear interpolation on two heights
02:09 PM mits5782[m]: and that is not thread lag.... I can run at any speed and it's awful
02:45 PM michal[m] is now known as _michal_0[m]
03:25 PM Unterhaus_ is now known as Unterhausen
03:27 PM Tom_L: Guido2665[m], with the or2 component
03:28 PM Tom_L: and no it may not be a great idea
03:29 PM travis_farmer[m]: what about sum2?
03:30 PM Tom_L: or depending on the logic you want, use the and2
03:30 PM Tom_L: not sure that's what you'd want for this
03:31 PM travis_farmer[m]: he wants to blend encoder inputs to one output. not sure bitwise logic will work...
03:31 PM Tom_L: i know
03:31 PM Tom_L: i doubt you need a float for that
03:31 PM Tom_L: it's a pulse train
03:32 PM Tom_L: sum uses floats with gain
03:32 PM Tom_L: so the or2 would work but may not be a great idea
03:33 PM travis_farmer[m]: i don't know, back when i was trying to use two encoders, i was told to sum2 them
04:15 PM JT-Shop: hmm Fedora is about a 3 mouse click install
04:24 PM Tom_L: JT-Shop, what are it's origins?
04:24 PM JT-Shop: Fedora?
04:24 PM Tom_L: yeah
04:24 PM Tom_L: i know nothing about it
04:24 PM JT-Shop: no clue :)
04:24 PM Tom_L: i knew about redhat but that's about it
04:24 PM travis_farmer[m]: i think it used to be Mandrake Linux
04:25 PM travis_farmer[m]: a RH clone
04:25 PM Tom_L: does it use debs or soemthing else?
04:25 PM travis_farmer[m]: RPMs
04:25 PM JT-Shop: no clue :)
04:26 PM travis_farmer[m]: Red-hat Package Manager
04:26 PM travis_farmer[m]: probably Yum by now
04:27 PM Tom_L: have you tried networking on it yet?
04:30 PM JT-Shop: no, I just pressed install and walked away
04:30 PM Tom_L: seems too easy for any install :)
04:39 PM zyp: by adding the encoders, I mean you first decode them separately and then add the counts together
04:40 PM zyp: doesn't seen to be a premade block that just adds two s32 values together though
04:40 PM travis_farmer[m]: easy enough to make a comp to do it
04:40 PM zyp: yeah
04:42 PM travis_farmer[m]: time to go to the store for some supper... signing off
04:43 PM zyp: since the actual count doesn't matter, just the change in count when you turn one of the MPGs, simply adding them means you can use both at the same time
04:43 PM Tom_L: i think the or2 would get you that same result
04:43 PM zyp: if you turn one of them 100 steps, it doesn't matter which, the sum will increase by 100 either way
04:44 PM zyp: no, bitwise or is only equivalent to addition if one of the inputs are zero
04:45 PM zyp: hmm, or2 is a boolean or, i.e. single bits
04:46 PM flyback: ve7it, BMCC
04:46 PM Tom_L: zyp, i think the hostmot2 encoder function would keep track of the counts
04:47 PM zyp: yeah?
04:47 PM Tom_L: http://linuxcnc.org/docs/stable/html/man/man9/hostmot2.9.html#encoder
04:47 PM zyp: so you get two counts, one from each, and you want to combine them to a single signal usable for jogging
04:47 PM Tom_L: i still think it's a bad idea
04:48 PM Tom_L: but it is possible the pulses could hit at the exact same time but unlikely
04:48 PM Guido2665[m]: travis_farmer @tom_L: thanks for the input. I don’t really want to fuse, I’d rather switch to make perfectly clear which enc is in charge. Switching ist also needed for axis and increment selection anyways.
04:49 PM Guido2665[m]: With regard to those concerns I’d rather keep things separate
04:49 PM flyback: power going down
04:49 PM flyback: ugh
04:50 PM zyp: axis selection is the opposite problem of encoder selection though
04:51 PM zyp: axis selection is a form of demuxing and doesn't have a risk of discontinuities since it captures the current count when an axis is selected
04:52 PM Tom_L: the point is, there are several ways to approach it depending on the desired result
04:52 PM Tom_L: as usual with lcnc
04:53 PM zyp: encoder selection is muxing and will cause discontinuities when you're switching from one encoder to the other, i.e. a sudden change of the count, and you want to be very sure that no axes are selected when that happens so nothing moves in response to that
04:54 PM Tom_L: i thought we were talking about MPG where they normally aren't turning
04:54 PM Tom_L: so there would be no count to count
04:54 PM Tom_L: :)
04:54 PM roycroft: another option would be to install a ma switch next to each mpg, which would enable that individual mpg
04:54 PM roycroft: that way you press and hold the button while you're using it
04:55 PM roycroft: when you release the button that mpg goes offline
04:55 PM Tom_L: capacitive touch MPG
04:55 PM roycroft: it would take a concerted effort to enable and attempt to use both of them simultaneously
04:56 PM Guido2665[m]: That’s precisely my original worry// reason I started asking questions. I could time delay the switch… I’ll have to see. For now: thanks everyone. Time to hit the hay
04:58 PM zyp: Tom_L, AIUI when a MPG isn't turning, it's counting neither up nor down, so the count output stays at whatever value it had after the last time it was turned
04:59 PM * roycroft is doing yard work today, along with painting, and is taking a brief break to keep from overheating
04:59 PM zyp: so when you have two MPGs that's not turning, they potentially have different counts, and so when you switch between them, you've got a change in the jog input value
05:01 PM JT-Shop: Tom_L, Fedora is Gnome and very difficult to really do anything... I think it's for morons
05:01 PM XXCoder: xfce mint here
05:02 PM XXCoder: next one I will install evenually, will be linux mint lmde
05:02 PM XXCoder: lmde is basically de-ubuntu-ed, an debian but made to look and work similiar to linux mint
05:02 PM JT-Shop: what is lmde?
05:02 PM roycroft: the guy who used to run the gnome project, if he still doesn't, wanted it to work just like windows
05:02 PM roycroft: so yeah, it's very difficult and for morons :)
05:03 PM JT-Shop: well it didn't cost me anything to check it out
05:04 PM roycroft: it's one of those systems where if you're willing to do things exactly as it's configured to do out of the box, you're fine
05:04 PM XXCoder: I want to move on from ubuntu, since theyre doing awful things with snap and stuff
05:04 PM roycroft: but if you want to do anything unusualy or interesting you'll be tearing your hair out trying to get it done
05:05 PM XXCoder: I dont like gnome at all
05:05 PM XXCoder: xfce all way for me
05:05 PM roycroft: i should go back outside before i get unmotivated
05:05 PM XXCoder: it does have defaults, but you can do everying as you like
05:08 PM JT-Shop: I think I'll look at xfce again and see if it's improved
05:09 PM XXCoder: keep in mind you can change layout to be anything
05:09 PM XXCoder: you can even make it look like gnome
05:09 PM JT-Shop: oh hell no
05:09 PM XXCoder: or windows xp lol
05:09 PM JT-Shop: can I make look like DOS 6.22?
05:10 PM XXCoder: bit diffult but maybe with dark theme? lol
05:10 PM * JT-Shop had another hen die today...
05:10 PM XXCoder: aw what happened?
05:10 PM JT-Shop: she has been sick and finally gave up just a bit ago
05:11 PM JT-Shop: couldn't get her to eat anything so some sort of internal problem
05:11 PM XXCoder: oh yes. control shift f1, use ctrl shift f7 to exit dos theme ;)
05:11 PM JT-Shop: I really hated windows 3.1
05:11 PM XXCoder: might be blockage
05:12 PM XXCoder: I barely used 3.11. mainly chip challenge, jeezball games, and most of was in dos play games like doom
05:12 PM JT-Shop: I used to play doom all the time and still have the cd
05:22 PM skunkworks[m]: doom was the best thing ever..
05:23 PM XXCoder: it was fun yeah
05:23 PM skunkworks[m]: I found the shareware cd at the local best buy for like 9 dollars. I saw that is was made by the same company that made wolfinstine 3d..
05:23 PM skunkworks[m]: the rest is history
05:23 PM skunkworks[m]: I don't really play games anymore - but I did get doom eternal.. It is pretty amazing.
05:28 PM JT-Shop: a buddy and me used to play doom on the 56k modem and tie up the phone lines for hours
05:29 PM XXCoder: wolfstein 3d was interesting. I also edited maps
05:29 PM XXCoder: didnt do too much, also edited doom maps but just a tiny bit
05:29 PM XXCoder: just to see how it worked
05:34 PM skunkworks[m]: JT-Shop: me too - also got 'novel in a box' networking kit - Me and my cousins would get together and network all our computers.. Coax...
05:34 PM JT-Shop: cool, never did that
05:36 PM skunkworks[m]: decent was probably my favorite game to play against others..
05:37 PM skunkworks[m]: https://store.steampowered.com/app/273570/Descent/
05:37 PM skunkworks[m]: I think I got it on GOG - but it didn't work very well..
05:39 PM XXCoder: i tried it back then and it was unplayable for me
05:40 PM XXCoder: doom makes me slightly dizzy, quake was last game I could play for hours though slightly dizzy
05:40 PM XXCoder: portal I had to play in 30 minute sessions or so
05:40 PM skunkworks[m]: I had not played games for years - but finally got a 'good' video card.. had to try some current games out.. csgo, doom eternal.. but - really haven't gotten back in to it..
05:40 PM XXCoder: I would highly recommand portal and portal 2
05:40 PM skunkworks[m]: Lol - I remember that. I could not watch someone else play.. Otherwise I would get really dizzy
05:41 PM skunkworks[m]: XXCoder - a co-workier who is a big gamer said I should play those games.. (portal)
05:41 PM XXCoder: I cant play portal 2, I saw small parts of it when watched neice play it
05:41 PM skunkworks[m]: Again - I don't seem to make time for it - so I doubt I would ever get deep into gaming anymore
05:42 PM XXCoder: portal took me quite a while to complete but it was fun whole way though it
05:42 PM skunkworks[m]: I get virtigo - but thankfully - it just feels like I am on a roller coaster - I don't get sick.
05:42 PM XXCoder: minecraft I could barely play, open skies is fine, mining I do slowly
05:42 PM JT-Shop: yup, same for me no time to play games any more
05:42 PM skunkworks[m]: Mainly when I am working on something low - like under a car.
05:43 PM XXCoder: then post-0car accient it was unplayable in nearly entirely
05:43 PM XXCoder: KSp was playable but I already played so much of it so didnt want to playa again lol
05:43 PM JT-Shop: iirc I used to play space invaders or something like that late into the night
05:44 PM XXCoder: nice
05:44 PM JT-Shop: can't remember the device...
05:44 PM XXCoder: yeah atari was so much fun
05:44 PM JT-Shop: ah yep atari it was
05:44 PM XXCoder: atari is common for that but not certainity
05:45 PM skunkworks[m]: LOL - my first computer was TI99/4a.. It had knock of games.. Munch man, car wars, TI invaders...
05:46 PM skunkworks[m]: off
05:48 PM XXCoder: fun
05:48 PM XXCoder: sadly we was too poor for c64 and stuff
05:48 PM XXCoder: atari wasnt legally taken by my moms boyfriend. it wasnt great
06:01 PM XXCoder: (atari was such fun, but tainted by it being stolen)
06:10 PM XXCoder: roycroft: might be interesting for you also https://youtu.be/cG60059J_ss
06:11 PM JT-Shop: oh my the trash smells bad the mouse bait went bad and was full of maggots... hind sight being 20-20 I should have pitched it into the woods
06:27 PM * JT-Shop calls it a night
07:35 PM XXCoder: JT-Shop: seems theres "chicken orbs" now lol
07:36 PM XXCoder: its like hamster ball but open cage so they can forage and not die from fox or something
08:25 PM roycroft: i did not finish cleaning up that garden bed today - i ran out of steam
08:25 PM roycroft: unfortunately, i never seem to be able to do this kind of heavy garden work when it's cool and overcast
08:26 PM XXCoder: aw
08:26 PM roycroft: whenever i'm able to schedule a block of time to do it it ends up being sunny and hot
08:26 PM XXCoder: its sunny here but I just dont feel like pruning vines down again
08:27 PM roycroft: it's going to be even hotter tomorrow, but i'm almost done
08:27 PM roycroft: i should be able to finish it tomorrow
08:27 PM XXCoder: nice
08:28 PM roycroft: i worked in the hot sun for about 4 hours today, and have about an hour left to do
08:28 PM roycroft: until i go to the back yard, which is a whole other story
08:29 PM roycroft: there's a good 20 hours of cleanup work to do there
08:37 PM Tom_L: brain says yes, body says hell no!
08:39 PM mits5782[m]: I'm like 80% sure there's a config item that prevents me from using coordinated moves when unhomed, right?
08:39 PM Tom_L: you can mdi but not run a gcode program until you home
08:40 PM Tom_L: afik
08:42 PM mits5782[m]: guh, I really wish I could prevent MDI
08:43 PM mits5782[m]: I just smashed my surface probe with an MDI without being homed on accident
08:44 PM mits5782[m]: NO_FORCE_HOMING, shit... there it is
08:44 PM mits5782[m]: that's my mistake
08:45 PM Tom_L: otherwise G28 or G53 wouldn't know where to go
08:47 PM Tom_L: mine is set to 1
08:47 PM Tom_L: on my rotary axis
08:48 PM Tom_L: err no that goes in [TRAJ] section
08:50 PM Tom_L: so i guess that does allow gcode to run un-homed
08:50 PM Tom_L: http://linuxcnc.org/docs/stable/html/config/ini-config.html#_traj_section
08:51 PM Tom_L: NO_FORCE_HOMING = 1 allows the user to make MDI moves and run programs without homing the machine first.
08:51 PM mits5782[m]: sure, but I had accidentally set it
08:51 PM mits5782[m]: not accidentally, set it and forgot from testing
08:54 PM Tom_L: i can't remember now but i did something different on the rotary axis so it doesn't home when i 'home all'
08:55 PM mits5782[m]: you can set vel to 0 then it doesn't move it
08:55 PM mits5782[m]: assumes homed at current position
08:55 PM Tom_L: right i just noticed that in my config
08:55 PM mits5782[m]: search vel
08:55 PM Tom_L: HOME_SEARCH_VEL = 0
08:55 PM Tom_L: HOME_LATCH_VEL = 0
08:57 PM Tom_L: and set the limits to 'infinity' for continuous rotation
08:57 PM Tom_L: MIN_LIMIT = -1e99
08:57 PM Tom_L: MAX_LIMIT = 1e99
09:14 PM mits5782[m]: I am baffled how PROBEOPEN file ends up with external offsets applied in the lines that are output
09:17 PM mits5782[m]: oh, there's a feedback signal from the stepper
11:14 PM mits5782[m]: I prefer loglog
11:17 PM roycroft: me too - loglog is my favorite scale on a slide rule
11:24 PM * mits5782[m] uploaded an image: (42KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/YYjvhVJCDDNuGJdccHPnyPYT/PXL_20230612_042302237.jpg >
11:24 PM mits5782[m]: my poor probe
11:50 PM Deejay: moin
