02:28 AM NoSpark: has anyone here done a timer delayed ESTOP using hal? I want to turn on my drives with machine.enable, but if an estop is triggered, I want to delay turning them off for several seconds
02:28 AM NoSpark: I have a hardware delay safety relay I will use at a later point, but for the moment, any advice?
02:48 AM NoSpark: I want to leave the power connected during ESTOP to allow the drives and spindle to safely stop before cutting power to the drives
03:36 AM jpa-: NoSpark: just put a "timedelay" HAL block between machine.enable and the drive enable
03:37 AM jpa-: it has separate on-delay (which you would set to 0) and off-delay
03:37 AM jpa-: several seconds sounds pretty long though
03:38 AM jpa-: usually drives would stop within half a second; spindle may take longer
03:38 AM NoSpark: It's a big and fast CNC router, 20000mm/sec over 5m
03:39 AM NoSpark: 2 seconds should be okay for the drives, and maybe 5 for the spindle (13kw 24000RPM with a decent brake resistor)
03:39 AM NoSpark: although I think the brakeing would power the spindle drive anyway?
03:40 AM jpa-: it probably will
03:40 AM NoSpark: the drives have seperate safety inputs for the ESTOP circuit which safely stop them as fast as possible
03:41 AM NoSpark: they are not designed to have their power cut while operating
03:41 AM jpa-: if you are reaching 20 m/s over 5 m distance, you are already able to accelerate/decelerate from full speed in less than 100 ms
03:41 AM NoSpark: so a simple delay sounds okay for the moment
03:41 AM NoSpark: jpa-: huh? that doesn't sound right....
03:42 AM jpa-: maybe you meant mm/min?
03:42 AM NoSpark: I'm reaching 20m/s over about 1m
03:42 AM NoSpark: thats not acceleration, that is linear velocity
03:43 AM NoSpark: I havn't finished tuning the accel yet
03:43 AM jpa-: accelerating from 0 to 20 m/s in 1 m distance means 200 m/s^2 acceleration
03:44 AM NoSpark: but it takes about 1 second to reach full speed, or come to a stop
03:44 AM jpa-: if it takes 1 second to accelerate to 20 m/s, then you have already moved 10 meters in that time
03:44 AM NoSpark: I must be wrong about the accel, it's def not 200m/s^2
03:44 AM NoSpark: maybe 40-20m/s^2
03:44 AM jpa-: and that would mean you can never usefully reach 20 m/s
03:45 AM NoSpark: true, the machine can't reach max V over it's length atm
03:45 AM NoSpark: but I will be increasing the accel soon
03:45 AM jpa-: (also: crazy speeds, i consider even 20 m/min "fast" :)
03:45 AM NoSpark: It's a massive produciton wood router
03:45 AM NoSpark: It's acceleration limited, not speed limited
03:46 AM jpa-: have you had to increase servo loop speed to reach that? because the delay 1 ms loop would have quite large inaccuracy at those speeds
03:46 AM jpa-: *default
03:46 AM NoSpark: It's not very well engineered, it have very small motors and used to have a 1 ton gantry
03:47 AM NoSpark: the drives have both the inner and outer loop, and linuxcnc provides a 3rd outer loop
03:48 AM NoSpark: I've stripped about 500kg of "safety" barriers from the gantry to try and increase the acceleration
03:48 AM NoSpark: I'm just starting to tune the system now
03:49 AM jpa-: if it is acceleration limited, it might help to adjust the transmission ratio from the motors; it is useless to have the gearing permit 20 m/s if you can't reach more than 5 m/s over the working area
03:49 AM jpa-: lower gearing would give better acceleration
03:49 AM NoSpark: I know, like I said, not very well engineered
03:50 AM NoSpark: It has high speed servos (12000RPM), with 10:1 gear reduction, and a rack and pinion that is about 60mm/rev
03:51 AM NoSpark: I think the engineer doesn't know what they are doing, but I"m just assuming for the moment that I am missing something
03:51 AM jpa-: calculating from those numbers gives just 1.2 m/s for me
03:54 AM NoSpark: I get 72 meters per minute
03:55 AM NoSpark: 12000RPM * 60mm/rev /10 gear reduction
03:55 AM NoSpark: am I doing something stupid?
03:56 AM NoSpark: so def not 20m/s (that is just completely wrong)
03:56 AM NoSpark: Once I've gotten further with turning, I'll post actual numbers, not just guesses
03:57 AM jpa-: RPM is per minute and not per second
03:58 AM NoSpark: 1.2m/s == 72meters per min, so yeah, I'm doing something wrong somewhere
03:58 AM NoSpark: I must have missed the gear reduction somewhere
03:59 AM jpa-: ah, yeah, you said that :)
04:32 AM Tom_L: morning
04:54 AM JT-Cave: morning
06:01 AM fogl: hello everybody
06:03 AM fogl: what is a typical way to control the pwm (0 to 1 input) with PID (-1 to 1 output)? Should i just scale the pid output to range from 0 to 1?
06:11 AM Unterhausen: seems to me that pid must be scaled already, to be limited to -1 to 1
06:11 AM Unterhausen: but just dividing by 2 and then adding 1/2 seems like an obvious way to fix the scaling
07:47 AM jpa-: fogl: if the actuator is bidirectional (e.g. motor can run both directions), you typically configure the PWM block to switch direction when input value is negative
07:49 AM jpa-: if the actuator is unidirectional (e.g. heater), i would use scaling to map +-1 to 0..1
07:53 AM fogl: Yes, i am planning to control the heater, thank you for your suggestion :)
09:57 AM Tom_L: jdh, what point were you starting from for the apt-get install linuxcnc for the RTAI? i may try testing that install
09:58 AM Tom_L: JT-Cave, what package do i need for gdebi? i tried installing debhelper
09:59 AM Tom_L: this ssd was a very early bookworm and the sources list may be pointing in the wrong spot
10:05 AM JT-Shop: Tom_L, to install gdebi it's sudo apt install gdebi IIRC
10:05 AM JT-Shop: bbl
10:05 AM Tom_L: my sources list is messed up i think
10:06 AM Tom_L: can you paste yours?
10:06 AM Tom_L: IP not found etc
10:12 AM Tom_L: found a ftp that seems to be doing something...
10:25 AM Tom_L: what is "PREEMPT_DYNAMIC"?
10:25 AM Tom_L: for a kernel
10:26 AM Tom_L: is that the new RTAI??

11:39 AM Tom_itx is now known as Tom_L
11:49 AM Tom_L: aparently chaning the grub boot order doesn't work as advertised.
11:49 AM Tom_L: GRUB_DEFAULT=8
11:49 AM Tom_L: sudo update-grub
11:49 AM Tom_L: seems to have no effect
11:50 AM JT-Shop: I use the grub customizer thing
11:50 AM Tom_L: https://linuxhint.com/change-grub-boot-order-debian-linux/
11:50 AM Tom_L: any ideas?
11:50 AM Tom_L: where do you find that?
11:51 AM Tom_L: installing
11:57 AM JT-Cave: heating devices all full of firewood time for a winter nap
11:59 AM Tom_L: so far that doesn't work either
12:00 PM roycroft: jt-cave: do your hens stop laying if they get really cold?
12:00 PM * roycroft is trying to figure out why there are no eggs in any stores here
12:01 PM JT-Cave: they stop laying around november but start back up in january so cold has nothing to do with it
12:01 PM roycroft: ok
12:01 PM roycroft: well we normally get eggs in abundance year-round, and don't pay a premium in the winter
12:01 PM JT-Cave: I "think" it's the shortening of daylight that triggers them to stop laying
12:01 PM roycroft: but as of a few days ago there are no eggs anywhere
12:02 PM roycroft: i thought it might be related to the extreme cold we had
12:02 PM roycroft: aah
12:02 PM JT-Cave: pullets will lay all winter and some breeds of hens will the second winter
12:02 PM roycroft: so you could probably get them to lay year-round if you kept them indoors under artificial light
12:02 PM Tom_L: still boots with the first kernel entry
12:03 PM Tom_L: did the grub customizer then sudo update-grub shutdown restart
12:04 PM Tom_L: customizer shows RTAI as the first option
12:04 PM JT-Cave: some breeds will lay all year long with artificial daylight
12:04 PM JT-Cave: why do sudo update-grub after using the grub customizer?
12:04 PM Tom_L: i figured you had to
12:05 PM JT-Cave: I just run the customzer and make my selections then save and it's done
12:06 PM Tom_L: there...
12:06 PM Tom_L: i'd moved it up in the sub menu
12:06 PM Tom_L: ok the RTAI for 12 seems to work ok
12:07 PM Tom_L: you need all 3 of those debs on the dl page though
12:08 PM JT-Cave: nap time
12:08 PM Tom_L: now if i had a mini itx board i could run it on the mill as a hardware test
12:09 PM Tom_L: i could put this ssd in the old board and see what the latency looked like
12:42 PM roycroft: the internet says that avian flu is the reason for the shortage
12:44 PM Tom_L: must be true then
12:49 PM roycroft: indeed
12:49 PM roycroft: the internet does not lie
12:49 PM roycroft: only internet users lie
12:50 PM Tom_L: i've found it to be a very reliable source of truth
12:50 PM Tom_L: :/
12:50 PM roycroft: it is a very reliable source of truth, but it is also a very reliable source of falsehoods
12:51 PM roycroft: caveat surfer
12:54 PM jdh: Tom_L: I was trying to follow the guide at: https://linuxcnc.org/docs/2.9/html/getting-started/getting-linuxcnc.html#cha:Installing-RTAI
12:55 PM Tom_L: jdh, i started with a debian 12 install, then installed those 3 debs from the dl page
12:55 PM jdh: ran the installer script that installed the preempt version, then apt-get install linxucnc which removed the preempt version and installed the rtai ones. But no kernel
12:55 PM Tom_L: you'll ned gdebi for the debs
12:56 PM Tom_L: i may try it on my mill later
12:56 PM jdh: anyone know how well this runs on an ancient Atom D525?
12:56 PM Tom_L: that may be what i have on the mill
12:56 PM Tom_L: i can't keep track...
12:56 PM Tom_L: i do have one of those
12:56 PM jdh: It's currently running 2.5.something
12:57 PM Tom_L: mine is running wheezy with 2.8.4
12:57 PM Tom_L: RTAI
12:57 PM jdh: The latency test and linuxcnc both locked up under the preempt
12:57 PM Tom_L: using the pp for a 7i90 card
12:57 PM Tom_L: if i get a chance i'll check the MB and try running this ssd on it
12:59 PM Tom_L: CPU-Z says this is an ASrock Q1900B-itx so it's very likely the mill is the D525
01:00 PM Tom_L: if not today, i'll test it in the next few days
01:01 PM jdh: Tom_L: you just downloaded teh debs and installed them? Not via apt?
01:01 PM Tom_L: rightt
01:01 PM Tom_L: you do need all 3
01:01 PM Tom_L: then use that gui grub config thing to re'arrange the boot order
01:02 PM jdh: I think the apt-get install linuxcnc installed everything but the kernel. I have the linuxcnc bins/etc and the modules.
01:02 PM Tom_L: grub customizer..
01:02 PM Tom_L: give it a try
01:02 PM Tom_L: that might be a modified linuxcnc for RTAI, i dunno
01:03 PM Tom_L: i wouldn't think so
01:08 PM JT-Shop: kroger has a limit on milk products
01:10 PM Tom_L: jdh, the mill _is_ using the D525MW board
01:10 PM Tom_L: i just brought it in to warm up a bit
01:36 PM flyback: https://www.omnicalculator.com/everyday-life/electricity-cost
02:00 PM Tom_L: jdh, http://tom-itx.no-ip.biz:81/~webpage/cnc/RTAI_TEST/RTAI_D525.png
02:01 PM Tom_L: that looks useable to me
02:01 PM jdh: is that acceptable? I'm trying to bring myself to go freeze to run the test
02:01 PM Tom_L: haha
02:01 PM Tom_L: i did :)
02:02 PM Tom_L: i'll get my configs set up on it soon and test it on the mill
02:02 PM Tom_L: use a spare ssd to try it :)

02:14 PM solarwind: Respect.
02:14 PM solarwind: He went out on his own terms. Didn't want to hurt anybody.
02:18 PM jdh: latency test looks like yours.
02:22 PM solarwind: "Officials were quick to point out that Russell, an employee of three and a half years with Alaska Airlines’ regional subsidiary Horizon Air, passed the background checks"
02:23 PM solarwind: LOL no shit they were quick, they only care about themselves
02:23 PM solarwind: "How Russell, who did not hold a pilot’s license, learned to fly the twin-turboprop Bombardier Q400 that had been parked up for the night is unclear."
02:23 PM solarwind: It's like people have never heard of flight sims...
02:23 PM XXCoder: solar please dont interrupt on-topic convo with unrelated
02:23 PM solarwind: fine
02:27 PM jdh: but, linuxcnc locked up
02:31 PM Tom_L: jdh, you try on hardware?
02:31 PM Tom_L: or sim or what?
02:31 PM jdh: hardware
02:31 PM Tom_L: i haven't tried that yet

05:23 PM Tom_L: did you merge the build?
05:23 PM Tom_L: i'll rebuild
05:24 PM JT-Cave: yup
05:24 PM Tom_L: i'll try it first
05:28 PM Tom_L: #78 up
05:34 PM -!- #linuxcnc mode set to +v by ChanServ
05:36 PM JT-Cave: thanks
05:36 PM JT-Cave: done
05:36 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/RTAI_TEST/RTAIlatency.png
05:36 PM Tom_L: cool
05:36 PM JT-Cave: looks good
05:36 PM Tom_L: that's on the D525 running 12.4 RTAI
05:37 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/RTAI_TEST/RTAI_D525.png
05:37 PM JT-Cave: that looks real good
05:37 PM Tom_L: jdh says his is a little sluggish but i may try running the torture test on it
05:38 PM Tom_L: https://www.youtube.com/watch?v=pOLsLrPLbUg
05:38 PM Tom_L: all axis 100 ipm
05:38 PM Tom_L: that was on wheezy though
05:39 PM Tom_L: rotate all axis 45 deg each pass
06:03 PM Tom_L: wheezy compared to bookworm:
06:03 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/RTAI_TEST/RTAI_D525_Wheezy.png
06:03 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/RTAI_TEST/RTAI_D525.png
06:04 PM Tom_L: pretty close to the same
06:06 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/RTAI_TEST/RTAI_D525_bookworm.png
06:06 PM Tom_L: just renamed the file
07:03 PM Tom_L: jdh, https://www.youtube.com/watch?v=b0VQFL-C72k
07:16 PM jdh: mesa?
07:16 PM Tom_L: 7i90 yes
07:16 PM Tom_L: thru the parport
07:17 PM Tom_L: seems as solid as the wheezy version
07:17 PM Tom_L: it takes a bit longer to boot
07:21 PM jdh: mine is pport stepgen
07:21 PM Tom_L: that would make a difference
07:22 PM Tom_L: but i still think it may work ok
07:22 PM Tom_L: did you see the latency comparison between 7 & 12?
07:22 PM jdh: yeah
07:22 PM jdh: holding down the arrow key in continuous mode stutters and continues for a long time after releasing the key
07:23 PM Tom_L: i'm using a pendant for jogging
07:23 PM Tom_L: the gui access might make a difference
07:23 PM jdh: it auto-converted my old config file. need to check the diffs
07:23 PM Tom_L: well, that's not gui though, just kbd
07:23 PM Tom_L: i just copied my config straight across
07:24 PM Tom_L: from 7 2.8.4
07:24 PM Tom_L: you would need to make some changes from 2.5
07:24 PM jdh: yeah, some axis/joint swap
07:24 PM Tom_L: the convert gets most of it but iirc some spindle stuff it may mix
07:24 PM Tom_L: miss
07:24 PM jdh: I commented out the spindle stuff
07:25 PM Tom_L: motion.spindle changed to just spindle.x.
07:25 PM Tom_L: and of course the joint stuff
07:26 PM Tom_L: iirc that was about it
07:31 PM Tom_L: yeah, motion.spindle changed in 2.8 to spindle.x.
07:32 PM jdh: not sure it is worth spending much more time one. It works fine on the old system
07:32 PM Tom_L: that was my initial thought
07:32 PM Tom_L: but i like to test the new stuff to see how it works
07:32 PM Tom_L: unless you need a new feature it may not be worth it for you
07:33 PM jdh: I'd like to see the non axis front ends
07:33 PM Tom_L: you'll need more cpu for that
07:33 PM jdh: need a mostly free decent computer to fall in my lap.
07:34 PM Tom_L: i was looking at mb because i didn't think 12 would work on the D525
07:34 PM Tom_L: i've got a couple spare i5 i7 chips
07:35 PM jdh: my mill has a d525 also, but mesa via pport
07:35 PM Tom_L: yours is mesa too?
07:35 PM jdh: and I haven't powered it up in a few years.
07:35 PM jdh: 7i34 + something
07:35 PM Tom_L: hmm
07:36 PM Tom_L: are you running servos?
07:36 PM jdh: Might not ever matter. I don't really have space to set it up
07:36 PM Tom_L: i don't have space
07:36 PM jdh: steppers & ball screw G0704
07:36 PM Tom_L: ahh ok
07:37 PM Tom_L: i had a 7i84 in mine until i blew it
07:38 PM Tom_L: the 7i90 was cheaper with more io
08:08 PM Tom_L: oops. gotta reboot

09:26 PM roycroft: i got the handle sleeves turned today
09:27 PM roycroft: about 2/3 of my time was spent tidying up the shop so that i could make a completely different kind of mess
09:27 PM roycroft: anyway, all that's left on the book press project is making the cosmetic repairs to the balls, painting them, and final assembly
09:28 PM roycroft: i'm by no means a wood turners, but they came out acceptably, at least for now
09:29 PM roycroft: if i change my mind i can always make new ones
09:30 PM XXCoder: did you decide to solder up or use bondo
09:31 PM XXCoder: er weld up I mean
09:32 PM roycroft: bondy
09:32 PM roycroft: bondo, rather
09:32 PM roycroft: a major reason being how long it would take to pull the 6ga extension cord out to the fabrication shop so i can use the welder
09:33 PM roycroft: i almost did that anyway, as i needed to weld the threaded rod to the bushing i made yesterday, except i decided to use a couple roll pins instead
09:33 PM roycroft: the extra machining to install the roll pins took way less time than getting the welder set up
09:35 PM roycroft: anyway, that project will be done in a few days, and i'll take some pics and post them then
09:51 PM XXCoder: cool :)
09:56 PM Tom_L: roycroft, pics or it never happened
09:56 PM roycroft: they will be forthcoming, i promise
09:59 PM roycroft: when i first installed the steel balls on the threaded rod, i worried that they might be too big - the proportions did not look right at all
09:59 PM roycroft: but with the wooden handle sleeves they look just right
10:07 PM XXCoder: man im so glad I got the cardboard cutter
10:08 PM XXCoder: so much easier to tyurn big boxes into small square cardboards for recycle
10:10 PM Tom_L: alot more cardboard to recycle nowdays
10:10 PM XXCoder: its 2 big boxes for my washer and ninja spin dryer
10:10 PM XXCoder: its been working wonderfully so im breaking boxes down
10:39 PM roycroft: i can just take big boxes, fold thm up a bit and stop them down flat, and set them out on the street next to the recycle bin
10:39 PM roycroft: the refuse company will pick them up without complaint or hassle
11:30 PM XXCoder: roycroft: sadlt not the case here. in bin or fee
11:30 PM XXCoder: whew finally broke down all boxes
11:37 PM XXCoder: my cutter is aboulte chinesium, brand is "ofikt"
