[10:44:44] <gloops> something good happened veek?
[10:44:56] <veek> gloops, yeah :)
[10:45:13] <veek> my cousin dropped in and she said she'd get me some edible bamboo :)
[10:46:04] <gloops> hmm edible bamboo, only time ive had that is from a chinese takeaway, i wonder if it grows here
[10:47:23] <veek> ah hmm.. pickled it's yummy
[10:47:52] <veek> and the culm is edible so.. if you have a greenhouse it could grow and yield
[10:48:06] * veek is not an expert in gardening
[10:48:40] -!- HSD has joined #linuxcnc
[10:50:33] <gloops> well just had a quick google, it does grow here, i dunno how id use it though
[10:51:07] <gloops> (it doesnt really go with our standard potatoes cabbage and leeks lol)
[10:51:18] <veek> i use it in the garden.. and i have hopes for making something structural with metal.. some guys made a bamboo bicycle
[10:51:36] <gloops> bamboo canes are useful yes
[10:51:57] <gloops> in fact becoming a big thing in flooring now
[10:52:23] <veek> grows like crazy and sheds leaves all over the place
[10:55:57] -!- JesusAlos has joined #linuxcnc
[11:00:12] <gloops> leaves are ok for the soil
[11:01:19] <veek> bamboo's shallow rooting.. it'll gobble up the top soil.. where I live, we have a concrete block next door that cuts of 1/2 the light to my plot so..
[11:02:30] <Rab> Shallow and deep rooting. It's almost impossible to control.
[11:03:46] <Rab> Supposedly the only way to stop it from spreading is to dig down .5m and install metal plate.
[11:04:08] <Rab> Or spend your life digging up the roots.
[11:04:40] <veek> we have the thorny stuff.. thorns about 12" long and 2D projections - razor sharp
[11:06:30] <Rab> I dunno what strain is common here, it's not like that. I think bamboo is cool, but in this climate it pays to exercise the same discretion you'd use with, say, ornamental kudzu.
[11:07:54] <gloops> hmm, problem plant here is japanese knotweed
[11:08:55] <gloops> apparently even if you drop a small piece of stem on the ground it will quickly root, notifiable to the authorities still i think
[11:19:13] <Loetmichel> Rab: bamboo grows like weeds, indeed. its a grass after all.
[11:19:40] <Loetmichel> but its not as bad as those ornamental kudzu stuff.
[11:20:37] <Loetmichel> you can easily contain it by ripping it out completely before it starts seeding. not that deep roots that you would "forget" something.
[11:21:04] <SpeedEvil> Or just mowing it
[11:21:21] <Loetmichel> SpeedEvil: it will come back if mowed
[11:21:30] <SpeedEvil> Not if you keep doing it.
[11:21:31] <Loetmichel> also: it needs a pretty sturdy mower.
[11:21:44] <SpeedEvil> I mean continue to mow it at 1"
[11:21:48] <Loetmichel> at lest the sorts that grow BIG
[11:22:00] <Rab> SpeedEvil, you can literally watch it grow. That would be mowing every few hours.
[11:22:21] <Loetmichel> if you continue to mow it at 1" it will simply be a "sturdy" variant of an english green ;)
[11:22:36] <Loetmichel> Rab: some sorts yes
[11:22:41] <SpeedEvil> That's what CNC mowers are for.
[11:24:00] <Rab> There's a war going on between bamboo sprouts and the floor of my shipping container...I guess CNC mower could be arranged.
[11:24:04] <Loetmichel> SpeedEvil: that said: a bamboo lawn would be nice... can double up as a wire brush .-)
[11:24:21] <SpeedEvil> :)
[11:24:41] <Loetmichel> Rab: let me guess: the container is losing?
[11:25:43] <Rab> Loetmichel, not yet, but I have an uneasy feeling.
[11:26:48] * Loetmichel wouldnt be surprised if a few 100 bamboo sprouts of the right varity can lift the entire shipping container up 100 ft...
[11:26:50] <Rab> The seedlings are pretty gross when they can't find light. Soft and pale. They grow around 1" dia, but you can reach under and pull them apart by hand.
[11:26:56] <Loetmichel> ... just by growing ;9
[11:31:20] <roycroft> seedlings?
[11:31:29] <roycroft> if they're bamboo that is exceedingly rare
[11:31:49] <SpeedEvil> seedlings is the wrong term
[11:31:50] <roycroft> bamboo plants flower once, then die
[11:32:00] <roycroft> and they usually live about 75-100 years before they flower
[11:32:08] <SpeedEvil> (for vegatative outgrowths of the main clump for propagation)
[11:32:26] <roycroft> they almost always "reproduce" by sending runners underground
[11:33:02] <mozmck> rhizomes
[11:33:07] <roycroft> yes
[11:33:08] <SpeedEvil> ^
[11:33:13] <roycroft> and they do that once/year - in mid spring
[11:33:18] <SpeedEvil> I thought that, but thought I might be wrong.
[11:33:25] <mozmck> I have probably 15 varieties of bamboo on my place
[11:33:35] <roycroft> but when they do, you can literally watch them grow
[11:34:00] <Rab> roycroft, my mistake, rhizomes.
[11:34:02] <mozmck> Yeah, I've measured some grow about 2' per day
[11:34:11] <SpeedEvil> Just two here (scotland). I'd guess 5m tall.
[11:34:12] <roycroft> a shoot can grow 10m over the course of a few days once the sprout emerges
[11:34:59] <Loetmichel> IIRC there are some types of bamboo that can grow 30m++ in a single summer
[11:35:01] <SpeedEvil> If you disconnect isolated parts of the clump at the edge, do they still die at the same time?
[11:35:10] <gloops> whats the nutritional value
[11:35:15] <roycroft> they don't do that, loetmichel
[11:35:19] <roycroft> they do all their growing at once
[11:35:22] <roycroft> over a week or two
[11:35:24] <gloops> i mean, im all for these crops you just stick and forget about
[11:35:27] <roycroft> then they are done growing forever
[11:35:32] <gloops> if they are worth eating...
[11:35:36] <Loetmichel> roycroft: s/summer/season
[11:35:46] <roycroft> the young, tender shoots are edible
[11:35:52] <SpeedEvil> gloops: you have to process them to make them edible.
[11:36:00] <SpeedEvil> gloops: On the plus side though - pandas are delicious.
[11:36:00] <roycroft> but after they start growing they're not
[11:36:16] <roycroft> you have to cut them when they first emerge to eat them
[11:37:07] * roycroft grows bamboo as a screening plant, as there are some two story townhouses right behind his back yard
[11:37:11] <mozmck> some bamboo shoots are edible without processing.
[11:37:23] <roycroft> they do not need to be processed
[11:37:33] <roycroft> they just need to be harvested as they emerge
[11:37:39] <roycroft> wait a day and it's too late
[11:37:57] <SpeedEvil> roycroft: I've wondered about fake bamboo clumps for screening - have containers with 60cm bamboo growing out the side, and stack em
[11:38:02] <veek> and soak them in water.. to remove toxins
[11:38:06] <mozmck> Some are bitter I think. I have varieties which are sweeter.
[11:38:13] <roycroft> i don't eat mine
[11:38:32] <mozmck> I have, but there is almost no nutrition in bamboo shoots.
[11:38:43] <gloops> hmm seems they have some nutritional value, vitamins and minerals, very low calories, high fibre
[11:38:44] <roycroft> bamboo can also be pretty useful as "lumber"
[11:39:13] <gloops> so, youve got a bamboo bush - do you get canes, like garden canes you buy in the shops?
[11:39:43] <mozmck> yeah, I have a forest of vivax and dulcis - both timber stuff.
[11:40:07] <mozmck> smaller varieties make the smaller canes you buy in the shops.
[11:40:22] <gloops> hmm, i might stick a few plants in this year
[11:40:34] <roycroft> bamboo is expensive
[11:40:53] <mozmck> I need to find someone to sell some of mine to then!
[11:40:57] <gloops> i notice its getting popular for flooring
[11:41:02] <roycroft> but if you get the spreading kind you can plant them pretty far apart and just wait a couple years
[11:41:19] <roycroft> if you get the clumping kind you have to buy a lot if you want a solid screen
[11:41:39] <roycroft> i don't grow clumping bamboo, but i'm told it can be divided successfully
[11:42:20] <roycroft> that's probably how it's commercially produced, since it only seeds once
[11:42:33] <roycroft> i'm sure not all clumping bamboo is wild harvested
[11:42:58] <gloops> ill have to check out the different varieties that grow here and what theyre good for
[11:43:24] <roycroft> bamboo is great for privacy screens
[11:44:57] <mozmck> gloops: I think the main thing you'll have to look for is cold hardiness
[11:45:45] <gloops> yeah needs to be hardy, looks like there are quite a few that do survive here though
[11:45:58] <mozmck> How cold does it get there?
[11:46:57] <veek> https://www.ncbi.nlm.nih.gov 'mass cyanide poisoning from pickling bamboo shoots'
[11:47:26] <gloops> it might get down to -10 rarely lower
[11:47:33] <gloops> -10C
[11:48:52] <gloops> looks like they were in the bamboo pickling pit though veek
[11:49:26] <veek> yep
[11:50:33] <veek> it contains toxins that are destroyed when heated
[11:51:14] <veek> same as cassava 'cyanogenic glycoside, in fresh bamboo shoots may lead to food poisoning when consumed'
[11:59:17] <roycroft> it got to -23 here three years ago and my bamboo did not die
[11:59:32] <roycroft> that, btw, was the lowest temperature ever recorded here
[11:59:41] <SpeedEvil> -15C I think here a couple years ago.
[11:59:44] <SpeedEvil> might have been three.
[12:00:02] <roycroft> most years -6 or so is the coldest we get
[12:00:28] <roycroft> ours is a fairly maritime climate
[12:00:33] <roycroft> tempered by the coast range a bit
[12:04:09] <Simonious> hat do solidworks call it when they model a part around an existing part? I call it scaffolding.

[13:25:37] <gloops> i might make a quick vid tommorrow
[13:25:59] <fragalot> so it hasn't happened yet but you're working on it. gotcha.
[13:26:05] <gloops> you cant laugh at its rudimentary construction - not now it is proven to work lol
[13:27:28] <gloops> haha, well ive got a few nice slices of ash - funny just a log, but when you pull the slice off and see whats inside...
[13:27:39] <fragalot> Aye
[13:30:33] <gloops> this was initially a bit of madness really, a few people asked about house signs made from an oval slice from a log, they sell them at some garden centres for stupid £s with the letters burnt on
[13:31:13] <gloops> why i would build a saw to make those i cant think, but it is a useful thing, lot of applications here

[14:00:48] <roycroft> i'm thinking about making my new workbench out of ash
[14:00:59] <roycroft> i really like the one that matt estlea made
[14:03:17] <Jymmm> lot of ash here, all you want for free
[14:04:52] <roycroft> i need a couple hundred board feet for the bench
[14:05:20] <FinboySlick> roycroft: Wood workbench?
[14:05:21] <cpresser> afaik digikey takes care of all duties
[14:05:21] <roycroft> it would be worth the trip down there for some free ash
[14:05:42] <roycroft> yes, finboyslick
[14:07:52] <FinboySlick> If I ever have a chance, I'd probably make a Roubo style workbench. They're pretty darn great.
[14:09:03] <gloops> ash boards are not so common here, but ash is strangely enough
[14:09:09] <FinboySlick> https://www.youtube.com Here's a terrible infomercial-style video about 'em.
[14:14:41] <FinboySlick> I'm pretty sure plans for this one are freely available somewhere.
[14:14:52] <roycroft> that is my plan, finboyslick
[14:15:02] <roycroft> i really like roubo benches
[14:15:21] <roycroft> the only downside is that the good roubo vise hardware is really expensive
[14:15:43] <roycroft> the stuff made by benchcrafted
[14:16:15] <roycroft> US$1200
[14:16:23] <roycroft> http://www.leevalley.com
[14:17:22] <FinboySlick> roycroft: Well, I'm sure a bit of patience on a lathe could get you something pretty similar.
[14:17:58] <roycroft> https://www.youtube.com
[14:18:13] <roycroft> there's matt's, done in ash with that same vise hardware
[14:18:52] <roycroft> i was going to use beech, which is pretty traditional for a workbench, but i really like his ash one
[14:20:12] <FinboySlick> roycroft: Ah, yes. I watched all of that video too when I discovered Roubo workbenches.
[14:20:36] <roycroft> if i could find some nice cast wheels similar to the benchcrafted ones, i'd make the rest of the hardware
[14:20:42] <roycroft> matt's a very talented lad
[14:21:43] <roycroft> i was going to build a traditional european bench - i even bought the vise screws for it years ago - but i really like the simplicity of a roubo bench
[14:21:50] <FinboySlick> roycroft: Take a page from Tom Lipton's baby bullet videos.
[14:22:14] <roycroft> i have a cheap bench currently, without a face vise and with a crappy tail vise
[14:22:18] <fragalot> those videos were godlike
[14:22:44] <roycroft> i built a stanton bench which is really useful for assembly and for sanding/planing things horizontally
[14:23:05] <FinboySlick> Semi-decent welds, good files and patience can get you pretty good 'castings'.
[14:23:15] <roycroft> i'm starting to build some cabinets now, but when those ar done i want to work on a new woodworking bench

[19:28:59] <Vitran> Odd issue. Hoping someone may know what is happening here. https://i.imgur.com
[19:29:06] <Vitran> The rps is working, but the rpm is not
[19:29:28] <roycroft> so my digital caliper finally arrived
[19:29:45] <roycroft> it was sold as "new, with damage to the packaging"
[19:29:45] <XXCoder> hows it roycroft
[19:29:54] <roycroft> i thought that meant that the case might be cracked or something
[19:29:56] <roycroft> but no
[19:30:10] <roycroft> it is the outer amazon-provided package that was damaged
[19:30:26] <roycroft> what came from mitutoyo was in perfect condition
[19:30:29] <roycroft> and i like it
[19:30:30] <XXCoder> lol so case and caliper is perfect
[19:30:32] <XXCoder> nice
[19:30:33] <roycroft> it has a nice balance, and is very accurate
[19:30:37] <roycroft> yeah
[19:30:45] <XXCoder> how about repeatability?
[19:30:45] <roycroft> $93 for it
[19:30:57] <roycroft> it's quite repeatable
[19:30:59] <XXCoder> ie go out and in few times, and measure again
[19:31:08] <roycroft> assuming the operator is consistent
[19:31:18] <roycroft> i'll have to go measure some gage blocks in a while
[19:32:02] <XXCoder> use rod to measure inner to outmost
[19:32:03] <roycroft> and it measures to 0.01mm/0.0005in
[19:32:16] <roycroft> a factor of two better than any other caliper i have
[19:32:41] <roycroft> yeah, i should do that
[19:32:44] <XXCoder> my first mitoyoto caliper was bit damaged by drop so it has .0005" difference insidemost to outmost blades
[19:32:46] <andypugh> Vitran:
[19:32:47] <roycroft> i have some telescoping gages
[19:32:53] <andypugh> Still there?
[19:32:57] <XXCoder> it got certified still but good to know
[19:32:57] <Vitran> yep
[19:33:08] <andypugh> You are looking at signals, not pins
[19:33:22] <XXCoder> hey andypugh hows things
[19:33:30] <andypugh> I guess that the rps feedback is straight from an encoder?
[19:33:36] <Vitran> yes
[19:33:59] <Vitran> As is, it is spinning up to max RPM on a PID of 1,0,0
[19:34:43] <andypugh> You probbaly want to run the PID on RPS both sides
[19:35:43] <andypugh> You can pretty much ignore RPM, except if you want an rpm display. And if you have PID and trust it, why bother?
[19:35:49] <pcw_mesa> The other way is to scale the feedback (60X) so you get feedback RPM for a meter etc
[19:36:15] <andypugh> Indeed, but frankly I don’t see the need
[19:36:16] <pcw_mesa> but Andys way is simpler for a start
[19:36:23] -!- Vitran_ has joined #linuxcnc
[19:36:31] <Vitran_> Sorry, internet over X10 isn't that good.
[19:36:51] <Vitran_> So should I change the RPM to RPS in the .hal file?
[19:36:58] <andypugh> On a lathe surface speed is “right” or “wrong” and the numbers are pretty irrelevant. On a mill the same is true, but it is harder to tell..
[19:37:37] <pcw_mesa> also best to tune 0,0,0 FF0=1 == open loop to verify that every thing else is OK
[19:38:17] <andypugh> Well, you just need to be consistent. Either feed the spindle PID with rps command and feedback or make an rpm feedback from the encoder and a x60 scale and feed the PID rpm feedback and command
[19:39:03] -!- Vitran has quit [Ping timeout: 256 seconds]
[19:39:04] <andypugh> Aye, that too. A spindle is typically FF0 = 1 and then a hint of I. P isn’t that much help except for maybe getting up to speed faster.
[19:39:15] <Vitran_> I think I am also having issues with the Output Scale number.
[19:39:49] <andypugh> That should probably be peak speed, but also needs to be scaled in RPS or RPM, for consistency
[19:40:06] <Vitran_> It is a 0-10V range, 4000rpm max. So I thought that the output scale would be 10/4000 = 0.0025
[19:40:32] <andypugh> No, should prpbably be 5000 rpm / 60 s
[19:41:11] <Vitran_> I was basing that number off of this http://linuxcnc.org
[19:42:37] <andypugh> Well, I am just guessing. What is the hardware?
[19:43:01] <Vitran_> Hardinge Superslant. It has an old Siemens spindle drive
[19:43:12] <Vitran_> The spindle drive has a tachogenerator feedback to itself
[19:43:20] <Vitran_> and the 7i77 has an encoder linked to it
[19:43:51] <andypugh> For a 7i77 you want scalemax to match the command and feedback max in the same units
[19:44:36] -!- HSD has quit [Remote host closed the connection]
[19:45:04] <Vitran_> Max is +-10 https://imgur.com
[19:45:25] <andypugh> So, 83.33 scalemax, -83.33 scalemin, and set command and feedback both to use RPS. FF0 = 1, P= 0, I= 0 D=0 and see what happend. Then add some I to get closer to set speed
[19:46:48] <andypugh> net pid.s.feedback to spindle-vel-fb-rps instead
[19:47:29] <andypugh> And set the INI scales all to +/- 83.33
[19:47:29] <Vitran_> What about spindle-vel-cmd-rpm => pid.s.command?
[19:47:48] <andypugh> set that to rps too
[19:48:27] <Vitran_> Am I setting the Output_Min_Limit to 83.33?
[19:48:34] <andypugh> We can’t tell from what is visible there, but I suspect that the feedback-rpm is just never linked
[19:48:58] <andypugh> Min lim probably wants to be -83.33. Or possiobly zero.
[19:49:41] <andypugh> Are you running the VFD +/- 10V or 0=10V + DIR?
[19:49:50] <Vitran_> +-10V
[19:50:06] <andypugh> OK, then definitely -83.33
[19:51:20] <Vitran_> It currently spins at~10rps, output voltage of .01666666V, Spindle-Vel-cmd-rps of 0.0166666
[19:51:55] <Vitran_> ah, problem
[19:52:03] <Vitran_> At higher rpm, the encoder is having issues
[19:52:04] <andypugh> That’s at S1?
[19:52:15] <Vitran_> That is at S1
[19:52:26] <Vitran_> Or, the parameters indicated?
[19:52:46] <andypugh> It’s possible that the VFD has a minumum frequency. It probably should have
[19:53:12] <andypugh> You might need to turn off the spindle encoder filter. PCW?

[19:54:09] <Vitran_> the HAL configruation, teh Spindle-vel-fb-rps keeps on dissapearing to 0
[19:54:18] <andypugh> What happens at actual practical spindle speeds?
[19:54:55] <Vitran_> As is, the Spindle-vel-fb-rps is showing 0
[19:55:02] <andypugh> You are unlikely to be doing much work at 2 rpm…
[19:55:04] <Vitran_> Right now it is doing 2000rpm
[19:55:33] <SpeedEvil> andypugh: machine settings for when you don't want it to wake you up
[19:55:57] <andypugh> Hmmm, is the spindle encoder scale ever being set?
[19:56:14] <Vitran_> On the encoder it wrote 5000
[19:56:38] <Vitran_> I was doing tests where I counted the rps of the encoder and back calculated it to find the scale
[19:56:53] <Vitran_> *there was a note on the encoder that it had 5000
[19:56:54] <andypugh> And the spindle is on encoder 0 and analogout 5?
[19:57:05] <Vitran_> https://i.imgur.com
[19:57:21] <Vitran_> uh, yeah. That was because I first had the spindle on alaogout 0
[19:57:31] -!- asdfasd1 has quit [Ping timeout: 246 seconds]
[19:57:37] <Vitran_> But then I learned that analogout 5 had a seperate enable pin
[19:57:40] <andypugh> It’s not a problem, just checking
[19:58:23] <andypugh> If the spindle is _actually_ doing 2000 rpm and the spindle feedback is 0.125 rps then something, somewhere, is a bit wrong
[19:58:48] <andypugh> But I see that you have ignored our advice about FF0, P, I and S
[19:58:51] <andypugh> (D)
[19:58:57] <Vitran_> ?
[19:59:10] <Vitran_> Sorry, what did I miss? I did a PID of 0,0,0,1
[19:59:36] <andypugh> Sorry, I was reading the wrong section. My mistake
[20:00:02] <andypugh> OUTPUT_SCALE needs to be 83.33
[20:01:26] <Vitran_> How did you find that number? Could that be added to the Spindle Drive tutorial that I linked above?
[20:04:26] <andypugh> 83.33 is your max spindle speed in RPS…
[20:04:49] <Vitran_> Ah. I see.
[20:06:24] <Vitran_> As is, I can get it up to 17rps/1020rpm using the +- dials below the spindle control
[20:06:47] <Vitran_> It does not seem to allow me to go faster, but likely some limit I set
[20:07:48] <Vitran_> It was. Max_output was set to 9
[20:08:56] <andypugh> It’s one of those comp;iated situations wherre you can use anything you want. But you do need to use the same thing everywhere.
[20:09:40] <Vitran_> I see the encoder stops reading when going faster than 900 rpm. I can make it go faster, but the encoder stops reading
[20:09:51] <andypugh> (You can, for example, set the spindle encoder scale low by a factor if 60 to get RPM directly, but then spindle synched motion can’t work)
[20:10:11] <andypugh> You might need to turn of the encoder counter filter
[20:10:30] <andypugh> PCW can tell you how, I expect. I need to sleep.
