01:13 AM Deejay: moin
01:52 AM lcnc-relay: <TurBoss> good morning
04:09 AM Tom_L: morning
04:23 AM JT-Cave: morning
05:20 AM JT-Cave: 64°F !!!
05:38 AM JT-Cave: time to ride
06:27 AM Tom_L: 82°F / 97°F
07:26 AM lcnc-relay: <vibram> What are the advantages of Ethercat solution compared to standard servo?
07:26 AM lcnc-relay: Because actual servos are quite simple to wire & configure, I'm not sure to see why Ethercat would be better?
07:33 AM Scopeuk: ethercat tends to move where things are, it can also reduce the number of devices in the chain. ultimately you will still have a servo drive and that connects to the servo the same way (although there are some integrated versions). the simplification comes between the servo drive and the host machine, ethercat is an ethernet link (and multiple
07:33 AM Scopeuk: controllers can be chained) compared to a step generator or mesa card which wires to all the indevidual servo drives
07:35 AM lcnc-relay: <vibram> OK I see
07:35 AM lcnc-relay: <vibram> thank you
07:36 AM lcnc-relay: <vibram> i watched a lot of YT videos regarding this technology and all the DIY side but looked very complicated for the small gain
07:40 AM lcnc-relay: <zincboy_ca_on> I don't see any machine performance improvement using ethercat vs analog servo drives. Depending on how it is configured it may be better than a simple step/dir drive. The advantages come in more in large systems with many drives or in high performance controls that have more advanced motion control algorithms than linuxcnc.
07:41 AM lcnc-relay: <vibram> OK I see
07:42 AM lcnc-relay: <vibram> also I find it more difficult to debug if you have issue
07:44 AM CloudEvil: And simplified cabling can be a thing.
07:54 AM jpa-: yeah.. the amount of wires in even a simple 3-axis servo setup is a lot
08:09 AM lcnc-relay: <vibram> indeed but at least you can follow each of them
08:09 AM lcnc-relay: <vibram> if you have an issue
08:32 AM lcnc-relay: <skunkworks8841> I would like to play with ethercat.. But time...
08:59 AM lcnc-relay: <captainhindsight_.> https://www.youtube.com/watch?v=MrBOTG9cAJ8&t=1s
09:00 AM lcnc-relay: <captainhindsight_.> https://www.youtube.com/watch?v=GQP3IN6NiCQ easy peasy with LCNC
09:00 AM lcnc-relay: <captainhindsight_.> who knows what they used
09:40 AM lcnc-relay: <roguish> https://jauriarts.org/_matrix/media/v3/download/matrix.org/ryPIloOsJUhWHABXTzWxPQbI/image.png
09:40 AM lcnc-relay: <roguish> check this forecast.....
09:52 AM JT-Cave: ouch
09:52 AM JT-Cave: https://forecast.weather.gov/MapClick.php?lat=36.76505000000003&lon=-90.40129499999995
10:57 AM Tom_L: i'll take that over the first one
10:59 AM Tom_L: 100
10:59 AM Tom_L: °F 50% rh
10:59 AM Tom_L: that was odd
12:26 PM JT-Cave: chickens are taken care of, shopping done, lunch, nap then I really need to a little work
12:28 PM roycroft: during my coffee break this morning i went out and put up the other clamp rack, and now all my clamps are neatly put away where they belong
12:31 PM JT-Cave: I thought you drank tea?
12:32 PM roycroft: i drink both
12:32 PM roycroft: but i only drink coffee early in the morning
12:32 PM roycroft: hence my ability to do something else during my "coffee" break
12:34 PM Tom_L: lunch
12:34 PM roycroft: it's not lunch time yet
12:35 PM roycroft: i skipped second breakfast today, but it's almost time for elevenses
12:42 PM Tom_L: are you 50% done moving by now?
12:45 PM roycroft: over 50%, i think
12:45 PM roycroft: and i'm going to get a pickup load of stuff today after work
02:05 PM JT-Shop: Tom_L, thanks for posting on the forum
02:08 PM Tom_L: i thought it might stir more interest
02:35 PM lcnc-relay: <skunkworks8841> the network attached tv tuner seems pretty good.. I just hooked it up to a wire and got the strongest station.. Now I should try the app on the smart tv.. (phone and pc seem to work)
02:59 PM lcnc-relay: <skunkworks8841> Smart TV app seems to work
03:38 PM Tom_L: JT-Shop, PR #38
03:40 PM Tom_L: the gcodes_lb wraps the text, does mcodes_lb? it didn't seem like it did when i loaded extra mcodes
03:42 PM Tom_L: ahh i see it... wordwrap is unchecked on that one
03:42 PM Tom_L: i'll check mine but you may want to
03:47 PM Tom_L: also align top on both. it looks better imo
03:47 PM JT-Cave: https://pasteboard.co/3o8AR5hOK6RF.png
03:47 PM Tom_L: is that the bp one?
03:47 PM JT-Cave: no
03:47 PM JT-Cave: it won't run down here
03:47 PM Tom_L: mmm
03:50 PM JT-Cave: well it might with a sim
03:50 PM Tom_L: is rpi 800 x 600?
03:51 PM JT-Cave: I think the one I have is
03:51 PM Tom_L: i don't think i can fit all that in that size..
03:51 PM Tom_L: if i do, i'll call it rpi something
03:52 PM Tom_L: is that a touch screen?
03:52 PM Tom_L: if so i'm not even gonna try
03:52 PM JT-Cave: you just need more tabs...
03:52 PM JT-Cave: my bp?
03:52 PM Tom_L: no the rpi screen
03:52 PM Tom_L: i figured your bp was
03:54 PM Tom_L: realistically i'll never use more than 3 offsets is why i only put G54..56
03:54 PM Tom_L: i seriously doubt many would
03:54 PM Tom_L: unless they've got 18 vises on a gantry etc
03:56 PM Tom_L: i didn't get very far with the qss file
03:57 PM JT-Cave: my little rpi screen in Coop Deux is a touch screen
03:58 PM Tom_L: 800 x 600?
03:58 PM JT-Cave: I think so, it's been a while since I programmed that one
04:00 PM Tom_L: i don't know anybody actually using that small screen on a mill do you?
04:00 PM lcnc-relay: <TurBoss> Ido
04:00 PM lcnc-relay: <TurBoss> * I do
04:00 PM lcnc-relay: <TurBoss> 😛
04:00 PM lcnc-relay: <TurBoss> the raspberry pi 7" screen i think is that size
04:01 PM Tom_L: maybe i'll see if i can come up with something
04:01 PM lcnc-relay: <TurBoss> Rewffp/srec1@
04:01 PM lcnc-relay: <TurBoss> fuckl!
04:01 PM Tom_L: turBoss, you running probe basic on it :D
04:02 PM lcnc-relay: <TurBoss> no custom vcp
04:02 PM Tom_L: axis?
04:02 PM lcnc-relay: <TurBoss> turbonc 😄
04:06 PM lcnc-relay: <TurBoss> https://github.com/kcjengr/TurBoNC
04:06 PM lcnc-relay: <TurBoss> this without the plot
04:06 PM lcnc-relay: <TurBoss> https://jauriarts.org/_matrix/media/v3/download/jauriarts.org/VQVmmbOnlTEbzUiCmprmbyIS/image.png
04:06 PM lcnc-relay: <TurBoss> 🙂
04:07 PM JT-Shop: nice clean interface
04:07 PM lcnc-relay: <TurBoss> thanks
04:08 PM Tom_L: yeah i kinda like that
04:08 PM lcnc-relay: <TurBoss> machine is running without the 3d
04:08 PM lcnc-relay: <TurBoss> it can't 😄
04:08 PM lcnc-relay: <TurBoss> the same but the gcode instead
04:08 PM Tom_L: bogs it down?
04:09 PM lcnc-relay: <TurBoss> the library i use for the ploter doesn't like the pi performance or opengl versions
04:09 PM lcnc-relay: <TurBoss> it runs slow
04:33 PM rdtsc2: I think the consensus is, everyone that has tried LinuxCNC on a Pi has then wanted something beefier. Maybe that will be different with the Pi5, dunno.
04:35 PM lcnc-relay: <roguish> OK, just hit 102
04:38 PM roycroft: my impression is that a number of folks have used a rpi for linuxcnc and have been happy with it, but they all use mesa ethernet boards to offload the real-time control stuff
04:39 PM xxcoder: yeah that was in my future plans, but dunno now lol
04:39 PM roycroft: i hope my impression is correct, because that's what i put together to control the cnc router that i have yet to construct, other than the controller
04:40 PM lcnc-relay: <TurBoss> I'm using linuxcnc-rio
04:40 PM lcnc-relay: <TurBoss> its super awesome
04:40 PM lcnc-relay: <TurBoss> https://github.com/multigcs/LinuxCNC-RIO
04:41 PM roycroft: does it let you lay on ipanema beach and girl watch while your part is being machined?
04:41 PM lcnc-relay: <die_limonade> Can linuxcnc-rio output a step/dir signal for a spindle?
04:41 PM lcnc-relay: <TurBoss> not tried
04:41 PM lcnc-relay: <TurBoss> but joints do work fine
04:42 PM * roycroft heads down to eugene to move a load of hardwood to the new shop
06:23 PM lcnc-relay: <big_kevin420> hey guys talkign about small screen
06:24 PM lcnc-relay: <big_kevin420> JT's screen is 800x600, all his other small gui was that resolution
06:24 PM lcnc-relay: <big_kevin420> but JT's screen is not the usual
06:25 PM lcnc-relay: <big_kevin420> the normal resolution for the RPi screen, and most other screens5/7inches are 800x480
06:30 PM lcnc-relay: <turboss> oh yeah thats true
06:30 PM lcnc-relay: <turboss> 800 480 😅
09:04 PM lcnc-relay: <skunkworks8841> https://jauriarts.org/_matrix/media/v3/download/jauriarts.org/qsWQXAZtRBiLzjFyKfQsFvxs/PXL_20240703_015717822.jpg
09:04 PM lcnc-relay: <skunkworks8841> this is how you test a networked over the air tuner?
09:17 PM Tom_L: is there any other way??
09:18 PM roycroft: 40 degrees here on saturday is the forecast
09:18 PM lcnc-relay: <skunkworks8841> Does anyone remember what flavor of Linux the bdi used?
09:19 PM roycroft: and my plan for satureday is to haul two loads of stuff
09:19 PM Tom_L: nope
10:11 PM rdtsc is now known as rdtsc_away
10:21 PM Tom_L: Ok. screens for a rpi size flexgui mill_3 http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/rpi_mill_3/Screens/
10:21 PM Tom_L: touch screen
10:23 PM Tom_L: subject to change
