12:42 AM miss0r: Goodmorning
12:46 AM hazzy-lab: miss0r: morning!
12:46 AM miss0r: So; anything interresting since I left for sweden? :]
12:47 AM * Wolf__ is thinking about starting a moving company https://i.imgur.com/P32UTAi.jpg , worlds fastest unloads https://i.imgur.com/H48nAj9.jpg
12:47 AM miss0r: lol
12:48 AM miss0r: hehe, so nothing technically interresting, atleast :D
12:49 AM Wolf__: I didn’t bother to take any pic of my welding so nope, nothing technical
12:49 AM Wolf__: least from me
12:49 AM IchGucksLive: morning from sunny germany
12:49 AM IchGucksLive: miss0r, geadwave at denmark ?
12:50 AM hazzy-lab: miss0r: Yeah, we figured out how to get more dec plcs in dxf2gcode, very interesting :D
12:50 AM miss0r: IchGucksLive: yeah. it is very hot here
12:50 AM miss0r: hazzy-lab: :D
12:50 AM XXCoder: this week will be... "fun" here also. pretty hot which means inside shop it will be nice and hot
12:50 AM IchGucksLive: stockholm calling for firetrucks
12:51 AM roycroft: we have a big fire in southern oregon, at the california border
12:51 AM IchGucksLive: at 30Deg in polarcycle is the northpole route open
12:51 AM roycroft: and a bunch of smaller ones around here
12:51 AM miss0r: IchGucksLive: Yeah, we've send a few, along with poland and italy. I think norway sent some too
12:52 AM roycroft: we are close to an air quality advisory right where i live
12:52 AM XXCoder: fire risk here, especually in east side of washington state
12:52 AM IchGucksLive: we are redy here it rained around 30liters so until thuesday save
12:52 AM roycroft: last year we had smoke in the valley through most of august
12:53 AM IchGucksLive: http://www.wettergefahren.de/warnungen/indizes/waldbrand.html
12:53 AM XXCoder: roycroft: how about heavy smoke for over a month lol
12:53 AM roycroft: for a couple weeks i had a hard time breathing, and could not function well
12:53 AM XXCoder: I was ill whole danged time due to that
12:53 AM roycroft: fortunately i was on holidays one week during that smoky period, and was on the coast
12:53 AM XXCoder: lucky you :)
12:53 AM roycroft: this is becoming an almost every year thing
12:53 AM IchGucksLive: the infrared Robo tracker is claiming all camp fire
12:53 AM roycroft: not a once a decade or two thing like it used to be
12:54 AM XXCoder: it will just become more common
12:54 AM pfred1: you live in a desert
12:54 AM IchGucksLive: Mother Nature is calling for Harvest
12:54 AM XXCoder: me? no
12:54 AM roycroft: i live in what used to be one of the wettest parts of the country
12:54 AM XXCoder: rainforest biome here
12:55 AM pfred1: it was dry here for a while but it just rained yesterday
12:56 AM roycroft: oregon has the most diverse climate of any state in the nation
12:56 AM IchGucksLive: the lake here is a rain retention basins
12:56 AM Wolf__: you can have the rain back, I’m sick of flooding every other week
12:56 AM roycroft: we have actual rain forest
12:56 AM roycroft: and actual desert
12:56 AM roycroft: and coastal climate
12:56 AM roycroft: and alpine climate
12:57 AM IchGucksLive: we got a 10 sq Km Bio Reservat where since 50years nothing happend on humen interfear
12:57 AM IchGucksLive: this is the highest risk
12:57 AM Wolf__: I spent the day workin on my truck in a inch of water in my driveway
12:57 AM roycroft: we did the opposite, ichguckslive
12:57 AM roycroft: we managed our forests too well for decades
12:57 AM roycroft: we tried to put out every fire as quickly as possible
12:58 AM roycroft: that only made matters worse
12:58 AM pfred1: yeah bad idea
12:58 AM roycroft: it just built up the amount of fuel
12:58 AM roycroft: and now we have super fires
12:58 AM pfred1: wild fire
12:58 AM IchGucksLive: roycroft, we also 300.000 m³ per year in wood harvest to our region alone
12:58 AM pfred1: dumb pale faces
12:58 AM roycroft: current strategy in our national forests and blm land is to keep the fires away from civilization
12:59 AM roycroft: but otherwise let them burn themselves out
12:59 AM IchGucksLive: we got 15 Forest fire trucks on standby around 100 Farmer traktors with 25.000 liters supply
12:59 AM roycroft: ichguckslive: i am not up to a bragging match, but i would advise you not to brag about lumber resources to someone living in washington or oregon :)
01:00 AM IchGucksLive: 5 Civil helicopers and 2 fleets of the US-Army
01:00 AM IchGucksLive: roycroft, agree
01:00 AM IchGucksLive: im in the largest forest of germany
01:01 AM IchGucksLive: roycroft, google maps Clausensee
01:01 AM IchGucksLive: and zoom out
01:01 AM roycroft: i've been in quite a few parts of europe, and i agree that germany has likely more timber resources than any other country in europe
01:01 AM roycroft: but as the saying goes
01:01 AM roycroft: americans thing 200 years is a long time
01:02 AM roycroft: europeans think 200 miles is a long distance
01:02 AM IchGucksLive: in the Blackforest have been 2 mayor storms harvesting good wood in past years
01:02 AM IchGucksLive: amd we now got around 1 mio Cubic meters in over
01:02 AM pfred1: 200 years is a long time
01:03 AM roycroft: the northeastern united states is more like europe in terms of population density and natural resource availability than the west
01:03 AM IchGucksLive: roycroft, NY state is almost like germany
01:03 AM pfred1: too much snow
01:03 AM IchGucksLive: XXCoder, has to many big hils to call it
01:04 AM XXCoder: lots hills here
01:04 AM IchGucksLive: pfred1, but we cope 1meter of snow no factor to traffic as 2inch in NY is the traffic brekdown
01:04 AM XXCoder: most times cant see max distance horzon
01:05 AM roycroft: the state of oregon is only 30% smaller than all of germany
01:05 AM IchGucksLive: ok im off 2 garden all waterhoses and resrvas barrels are filled
01:05 AM IchGucksLive: roycroft, oregon has also gread plains
01:05 AM IchGucksLive: lots of farming
01:06 AM IchGucksLive: as Brandenburg in germany
01:06 AM roycroft: germany has 20 times the population of oregon
01:06 AM pfred1: farming is a big thing
01:06 AM roycroft: yes, both east and west of the cascades
01:06 AM pfred1: it's no wonder we'r all fat given all the food we produce
01:06 AM roycroft: to the west, where i live, we grow a lot of market crops, seed crops, berries
01:06 AM roycroft: we grow
01:07 AM roycroft: just north of where i live the majority of the world's grass seed
01:07 AM XXCoder: high fat food is easier to buy and grow than healthier food.
01:07 AM IchGucksLive: pfred1, that is us my familiy https://www.youtube.com/watch?v=f_PslBNAT7s
01:07 AM roycroft: we are also a major hops growing area
01:07 AM roycroft: just east of the cascades, in the high plains, there is a lot of cereal grain fields, and a lot of ranches
01:08 AM roycroft: in eastern oregon there are large range ranches
01:08 AM IchGucksLive: roycroft, ive been 2days in Yakima Valle this year
01:08 AM roycroft: neat
01:08 AM roycroft: i'm thinking of heading up there next month to buy some fruit
01:08 AM roycroft: a lot of hops are grown there
01:08 AM roycroft: also a lot of stone fruits
01:08 AM IchGucksLive: for presenting the New Fully Remote rock/Hill harvester from JD
01:09 AM Wolf__: for rock farming?
01:09 AM pfred1: 100 years ago half the populaiton farmed
01:09 AM IchGucksLive: Did you guys see the Auto Touchprobe Routine Video i made yesterday
01:10 AM IchGucksLive: Wolf__, Wood
01:10 AM roycroft: 100 years ago the entire population ate
01:10 AM IchGucksLive: Wolf__, Forest Hill Harvest
01:10 AM roycroft: today it also eats
01:10 AM pfred1: IchGucksLive how would you like to be out there with a sythe harvesting?
01:11 AM IchGucksLive: only 2 People in the area
01:12 AM IchGucksLive: im off
01:56 AM Deejay: moin
01:58 AM gloops: kinda getting there with blender https://ibb.co/c9QKZJ
02:02 AM Deejay: whee, nice
02:22 AM gloops: a bit more practice ill have modelling for most things covered i reckon, useful tool to have
02:26 AM XXCoder: blender seems good for that yeah
02:36 AM gloops: can actually make pretty much perfect copies of things, an important thing is working out how the basic mesh needs to go, and build it first time, gets very tedious if you have to go back and unpick it and alter it later
02:37 AM gloops: (like i bodged it with that scroll lol)
05:12 AM jthornton: morning
05:27 AM Tom_L: morning
05:29 AM XXCoder: morning
07:00 AM Beachbumpete1: Good Morning LinuxCNC
07:02 AM skunkworks: who is this linuxcnc person?
08:46 AM gloops: im not sure this fan is doing anything, its just circulating hot air
08:55 AM sync: djdelorie: do you know how to hook up the terminal to a desktop series data general machine?
08:55 AM sync: I seem to be missing the board edge connector to db connector and so far cannot find a schematic
09:14 AM cradek: c!
09:37 AM IchGucksLive: hi all
09:41 AM IchGucksLive: requested english touch off auto Video on the YT
09:43 AM IchGucksLive: off till later
10:13 AM seb_kuzm1nsky is now known as seb_kuzminsky
10:33 AM IchGucksLive: Hi
10:33 AM IchGucksLive: can someone check the english version of AutoTouchoff
10:33 AM IchGucksLive: https://youtu.be/0EgMakqWgwM
10:34 AM `Wolf: *watching
10:34 AM IchGucksLive: Thanks
10:35 AM IchGucksLive: Somthing must happen yesterday i see 417 Clicks on Videos comming from low <10
10:36 AM IchGucksLive: 120 alone on SETUP Debian 3Axis DB25 1205 AXIS
10:37 AM `Wolf: seems ok, I have heard worse by native english speakers
10:37 AM IchGucksLive: ;-)
10:37 AM IchGucksLive: ok
10:38 AM IchGucksLive: Thanks off till later
10:38 AM `Wolf: I really need to check in to probing routines in lcnc…
10:39 AM `Wolf: after I get the X2 built anyways
10:45 AM roycroft: it was fairly clear when i left my house this morning, but as i got closer to work the air became somewhat smokey
10:46 AM roycroft: the nearest fire is well to the southeast of here, so i'm not sure where the smoke is coming from
10:49 AM roycroft: the wind is from the northeast, so it could be from the substation fire, but that's up on the columbia river, far from here
10:49 AM roycroft: and it's on the other side of the mountains
10:53 AM Roguish: roycroft: where the heck are you?
10:59 AM enleth: so I'm looking forward to bolting some large and heavy stuff together using long rods with nuts on each end and I'm wondering whether there's a significant difference between using a smooth rod threaded at the ends only versus using all-thread, all other factors (steel grade, diameter, length, other hardware involved) being identical
10:59 AM enleth: obviously I'm not talking about hardware store all-thread
11:02 AM `Wolf: I would think the threaded at ends only would have less stretch, higher yield
11:03 AM `Wolf: but thats just a guess
11:03 AM enleth: same here, OTOH their weakest point is going to be identical
11:04 AM `Wolf: yeah, more likely to shear at the nut
11:05 AM enleth: I'm pretty sure I'm going to go overkill with steel grade anyway, so it's more of an academic question
11:07 AM `Wolf: my guess come from years if twisting bolts and studs off =)
11:07 AM enleth: for one, getting a high grade all-thread is easier than same-grade smooth rod with threaded ends
11:07 AM `Wolf: s/if/of
11:07 AM `Wolf: yeah length depending that is a factor
11:08 AM enleth: I mean, I'd probably have to order the latter custom made
11:08 AM `Wolf: if its short enough you could get something like TE-CO roll threaded studs like used for hold downs
11:08 AM enleth: or try to thread a smooth rod of high-grade heat treated steel
11:08 AM Roguish: 'Wolf: separate the ideas of stiffness and strength. they are very different concepts. Wikipedia is your friend
11:10 AM enleth: I'm pretty sure I *want* some amount of stretch in the rods here, to prevent the whole thing from loosening up momentarily under dynamic loads
11:10 AM `Wolf: yeah thats given in bolting things, no stretch = no clamping force
11:10 AM enleth: some means of nut retention, too
11:11 AM enleth: tl;dr finally getting around to bolting the robot to the floor
11:11 AM enleth: or *through* the floor, actually
11:11 AM `Wolf: how long of a bolt in what thread?
11:12 AM enleth: AFAIR the holes in the base take M20 rods, 8 of those in a rougly equal spacing along the circumference
11:14 AM enleth: the floor is about 40cm thick including the arching, add up to 10cm on each side for spreader plates/griders and it comes to about 60/70cm between nuts
11:14 AM `Wolf: well TE-CO makes M20x2.5 from 80mm-300mm long http://catalog.te-co.com/viewitems/driver-studs-threaded-rod/metric-studs
11:16 AM `Wolf: which are too short lol
11:17 AM enleth: I'll be looking at local suppliers anyway
11:19 AM `Wolf: well, 5.8 m20x3.5 122KN tensile strength
11:21 AM `Wolf: seeing you are saying this is getting bolted through a floor you should probably be fine =)
11:40 AM djdelorie: sync: all the dg terminals I've used has rs232 connectors, sorry.
11:41 AM cradek: djdelorie: pop it open and look for the line driver/receivers and trace it out. should not be hard to figure out if you have a scope and know a little about serial.
11:41 AM cradek: the chips will be 1488/1489 or 15488/15489 or similar
11:42 AM djdelorie: cradek: well, all the dg terminals I've used, stayed at DG when I left decades ago.
11:42 AM cradek: err I meant sync:
11:54 AM djdelorie: the only caveat is that it might actually need +- 12v instead of the usual 0-5 we use today
11:58 AM IchGucksLive: hi all

12:18 PM IchGucksLive: maybe first wildfire but more likly someone missing in Frorest
12:18 PM IchGucksLive: 3/4
12:18 PM `Wolf: I need 1” right now
12:18 PM IchGucksLive: grab it at the pooolguys box
12:20 PM `Wolf: my whole plumbing system froze last winter in the house I’m renovating, broke my water filter housings (3) and the well pump =/
12:20 PM IchGucksLive: here it is up to 4meters deep so no problem to freeze
12:21 PM `Wolf: inside the house
12:21 PM IchGucksLive: the house is isolated
12:21 PM IchGucksLive: full stone and concrede
12:21 PM `Wolf: mine is 2 foot stone wall, but 1800 wood walls
12:21 PM IchGucksLive: and we got 4 snowplows
12:22 PM `Wolf: was so cold last winter that the stuff in my cellar froze
12:22 PM `Wolf: no heat in the house due to being under renovation
12:23 PM IchGucksLive: You need to get more prepared as Donald T cals for harder stuff
12:23 PM IchGucksLive: Second siren attempt i need to go looking whats up outside
12:24 PM IchGucksLive: BYE Gn8 From Germany
01:02 PM adamj12b: Can anyone tell me the advantages/disadvantages of the 7i76e vs a 5i25 & 7i76 for a plasma table?
01:09 PM gloops: yes there are people here who can adamj12b
01:10 PM gloops: well, here..when theyre here
01:17 PM `Wolf: just ping pcw_home pcw_mesa or jthornton
01:20 PM pcw_mesa: Ethernet is better in general for Plasma (better isolation of Plasma EMI from host PC)
01:21 PM JT-Shop: adamj12b: if you need a bit less I/O the 7i96 is more cost effective.
01:21 PM JT-Shop: https://mesaus.com/index.php?route=product/product&path=66&product_id=150
01:23 PM adamj12b: JT-Shop: Thats the one I was looking at if I went Ethernet.
01:23 PM pcw_mesa: 7Ii96 does need master though...
01:23 PM adamj12b: pcw_mesa: What do you mean it needs master?
01:23 PM pcw_mesa: master and Preempt-RT so more trouble on initial set-up
01:23 PM `Wolf: I’m back to thinking about ethernet + analog servo motors for my cnc plasma now
01:24 PM pcw_mesa: it need the development version of LinuxCNC (2.8)
01:24 PM pcw_mesa: needs
01:24 PM pcw_mesa: for full support
01:24 PM adamj12b: Well I was looking at 2.8 anyways for the gantry improvements
01:25 PM pcw_mesa: Yep, if you have a gantry system you may want 2.8 anyway
01:26 PM adamj12b: and there shouldnt be any issue with 7i96 vs 7i76 using the THC board on the encoder input?
01:27 PM pcw_mesa: its the same
01:29 PM `Wolf: I wonder, has anyone has done a sliding arm type cnc plasma using lcnc
01:30 PM `Wolf: esab crossbow type thing
01:33 PM adamj12b: `Wolf: Thats a pretty cool system. Wouldnt be very hard
01:34 PM `Wolf: shouldn’t be, I’m liking the idea for space saving when not in use
01:34 PM jthornton: I made mine so I could slide the sheet through the plasma if needed
01:35 PM `Wolf: yeah, using that idea with mine as well, short axis reach and just split the sides on wide stuff
01:35 PM `Wolf: er long
01:36 PM adamj12b: my design im working on has a 2ft Y and 4ft X with open front and back like your talking about.
01:36 PM `Wolf: thinking 5’ carriage track and maybe 3.5’ cutting reach on the arm
01:37 PM `Wolf: most of the plate cutouts I do are only 3’ wide, the tubes I need to put holes in are 8’ long tho

06:25 PM hazzy-lab: nice
06:27 PM robotustra: didn't break any endmill yet today :)
06:28 PM Tom_L: did you run anything?
06:28 PM Tom_L: i was gonna but haven't yet
06:29 PM Tom_L: working on a couple cad parts
06:29 PM `Wolf: Ugh, part of my day… https://i.imgur.com/CzYKJ9w.jpg
06:29 PM robotustra: yes I'm running now
06:30 PM Tom_L: just air or coolant?
06:30 PM Tom_L: looks like air
06:30 PM robotustra: just air to blow chips
06:31 PM robotustra: I mill aluminum usually dry becase chips are small and fly away by blower
06:31 PM Tom_L: i think when i use coolant i get a better finish
06:32 PM Tom_L: so the stepper is gonna slide for adjustment?
06:33 PM robotustra: I'll show you my finish in a 1/2 hour
06:33 PM robotustra: yes
06:33 PM Tom_L: i may be out milling by then
06:33 PM Tom_L: doubtful, i'm feelin kinda lazy now
06:35 PM robotustra: he he
06:37 PM GuestPerson: The time is correct now, thanks
06:40 PM Tom_L: good to know
06:44 PM hazzy-lab: `Wolf: What happed to the welder?

06:48 PM Wolf_ITX: thats with it set at 200 out...
06:49 PM hazzy-lab: Wolf_ITX: I was kidding, thats all its good for at 8A
06:53 PM Wolf_ITX: just a formerly expensive doorstop right now
07:01 PM Wolf_ITX: I really want this thing working again...
07:05 PM robotustra: рь
07:05 PM robotustra: hm
07:05 PM robotustra: made a mistake
07:05 PM robotustra: motor ring is 38 mm, I did 36
07:05 PM robotustra: have to mill 2 mm more
07:06 PM GuestPerson: i dislike xfce
07:15 PM MrHindsight is now known as CaptHindsight
07:18 PM Wolf_ITX: then load something else
07:21 PM GuestPerson: Will it mess with timing or something?
07:22 PM CaptHindsight: .weather beer
07:22 PM theCockerel: Yahoo! Weather - Beer, England, GB: Partly Cloudy, 17°C (62°F), Humidity: 91%, Gentle breeze 4.9m/s (→)
07:22 PM GuestPerson: I would like lxde , or just openbox
07:23 PM CaptHindsight: changing desktops won't effect kernel latency
07:24 PM Wolf_ITX: if you check the forums, there are other full builds of linux cnc
07:24 PM GuestPerson: :O
07:25 PM Wolf_ITX: i'm on a mint build right now
07:33 PM robotustra: CaptHindsight, actually the latiency is different but not so much
07:33 PM robotustra: I tried plazma
07:33 PM robotustra: amd xfce
07:33 PM robotustra: xfce wins
07:34 PM robotustra: just do "apt-get install kde-standard"
07:35 PM robotustra: or "sudo apt-get install kde-standard"
07:35 PM CaptHindsight: I miss Gnome 2
07:35 PM robotustra: so install gnome
07:35 PM robotustra: apt-get update
07:35 PM CaptHindsight: sometimes I use LXDE
07:35 PM robotustra: apt-get install gnome
07:36 PM CaptHindsight: sometimes I run headless
07:36 PM CaptHindsight: I usually avoid Debian as well
07:37 PM CaptHindsight: robotustra: did you see latency difference between desktops using the same RTAI kernel?
07:39 PM robotustra: yes
07:39 PM CaptHindsight: robotustra: or when using the same preemt_rt kernel with different desktops?
07:39 PM robotustra: the same kernel and different desktop
07:39 PM CaptHindsight: robotustra: what version of RTAI?
07:40 PM robotustra: the latest one which is in the last version of linux cnc
07:40 PM robotustra: I installed it 2 days ago
07:41 PM CaptHindsight: did you compare latency after rebooting at least once or twice after the install?
07:42 PM robotustra: yes
07:42 PM robotustra: I installed with xfce
07:42 PM robotustra: tested it
07:42 PM CaptHindsight: how different were the results?
07:42 PM robotustra: not very big
07:43 PM CaptHindsight: how big is not very?
07:43 PM robotustra: I would say less then frections of percent
07:43 PM R2E4: Can I get rid of all the PID stuff in stepper config with 7i76? First time on stepper machine.
07:43 PM R2E4: hi All....
07:44 PM robotustra: and it looks like jitter was LESS on kde-plazma than on xfce
07:46 PM GuestPerson: Yes, lxde, thank you irc
07:47 PM R2E4: lxde is fast
07:54 PM GuestPerson: gotta get it set up comfy now
07:59 PM robotustra: finally https://imgur.com/udt8ARS
07:59 PM robotustra: https://imgur.com/HxGcguE
08:41 PM hazzy-lab: R2E4: I think the PID parameters might still be needed even for a stepper machine, I think they are used by the stepper generator. I asked a long time ago and remember I was told to leave them, can't remember why though
10:03 PM R2E4: Hi all
10:04 PM R2E4: 2.8 pre, What ever I set in the ini file max velocity and default velocity, it doesnt change when I jog and what shows up on the screen.
10:04 PM R2E4: in axis, Which ini file entry changes the velocity in axis for jog speed and max velocity?
10:05 PM R2E4: I put all max and default velocity to 1 and it is still 180 on the screen
10:18 PM pcw_home: did you set MAX_LINEAR_VELOCITY in the display section?
10:40 PM R2E4: yes
10:42 PM hazzy-lab: R2E4: You need to set it in TRAJ
10:44 PM R2E4: traj is max velocity for any cordinated move for any axis. I am setting that and the max is not changing for my X. I set it in joint 0 and axis x section also. weird behaviour
10:46 PM R2E4: have it set for 7 in traj and 7 in axis and it only goes 240, should be running at 420 no?
10:47 PM hazzy-lab: R2E4: sorry, the DISPLAY velocity settings are the ones you want to change
10:47 PM R2E4: The display is for jogging
10:48 PM hazzy-lab: yes, that is what the GUI uses
10:48 PM hazzy-lab: and the GUI handles the jogging
10:49 PM pcw_home: MAX_LINEAR_VELOCITY sets displays maximum jog and velocity
10:49 PM R2E4: I am running in mdi, G1 F400 x40 it is running at 240
10:50 PM R2E4: I'll set it to 7 also and see.
10:52 PM R2E4: https://pastebin.com/dTzWwKQ9
10:52 PM R2E4: Thats what I am running and it wont go over 240.
10:53 PM R2E4: I just pulled the latest master today
10:54 PM hazzy-lab: [AXIS_X]
10:54 PM hazzy-lab: MAX_VELOCITY = 4
10:54 PM hazzy-lab: Thats your problem
10:55 PM hazzy-lab: the jog speed can't exceed the max joint or axis speed
10:56 PM R2E4: thanks, that did it. Dont know why sometimes I try to go too fast and dont see simple little things like that.
10:57 PM hazzy-lab: R2E4: is is very easy to do, happened to me more than once, lol
11:06 PM R2E4: max velocity overides traj max velocity
11:07 PM R2E4: max velocity in display section overides max velocity in traj section
11:10 PM pcw_home: Not really, it sets the slider limits, but not the physical axis/joint limits
11:12 PM R2E4: I just tried it. traj is set to 7 and display section is set to 5 and it wont go over 300 if I command in mdi
11:13 PM pcw_home: you can set the display limits to 100 MPH if you want
11:14 PM pcw_home: right it bounds the trajectory numbers but does not override them
11:16 PM R2E4: ok, Is that the way it should be?
11:17 PM R2E4: I would think the display should be for jogging, and traj should be for any coordinated move.
11:17 PM pcw_home: yes so you can limit limit the maximum speed from the GUI when appropriate
11:18 PM pcw_home: say you want to run a program slowly at first
11:18 PM R2E4: ok, I'll see how it acts if I lower the traj below the display max velocity. ANy guess what that would do?
11:19 PM pcw_home: run with the trajectory limits
11:19 PM R2E4: I'll try it..lol
11:22 PM R2E4: it follows the display max velocity.
11:23 PM R2E4: WTF?
11:23 PM pcw_home: No, its bounded by display max velocity (which you can set to anything)
11:25 PM pcw_home: that is if I set [DISPLAY] MAX_LINEAR_VELOCITY to 21000 IPM (I just did on this test system)
11:27 PM pcw_home: I cannot move faster than the vector sum of the linear [TRAJ] velocities
11:27 PM R2E4: is an mdi command considered as a coordinated move?
11:28 PM pcw_home: depends on the command (G0 is not coordinated)
11:28 PM R2E4: G1?
11:28 PM pcw_home: yes
11:29 PM pcw_home: g0 also is not controlled by feed rate limits
11:31 PM R2E4: So if I do an mdi command, it should stay within the bounds of traj max velocity. correct?
11:31 PM R2E4: no matter what the display max velocity is set at.
11:32 PM pcw_home: the maximum velocity will be bounded by display max_velocity
11:33 PM pcw_home: but setting the display velocity higher will not cause the trajectory limits to be violated
11:35 PM R2E4: ok..... I think I got it.
11:36 PM pcw_home: of course a XYZ move could move at sqrt(XTrajVel^2+YTrajVel^2+ZTrajVel^2)
11:36 PM R2E4: thanks. later...
11:40 PM Letchy: hello
11:41 PM Letchy: im new to LinexCNC and i have a quick question, will this software work fine with any motor driver board? I will run it through Ubuntu but the motors will be using this board, https://www.ebay.com.au/itm/5-Axis-CNC-Stepper-Motor-Driver-Controller-Breakout-Board-MACH3-Interface-TB22/273107975069?hash=item3f9680fb9d will that be fine?
11:42 PM pcw_home: yes LinuxCNC should work with any standard parallel port breakout
11:49 PM Letchy: Thank you
