01:43 AM gloops: funny, there doesnt appear to be any source of scrap tin
01:47 AM gloops: copper, brass, alu, silver gold yes, but not tin
02:15 AM Deejay: moin
02:30 AM miss0r: mornin
03:45 AM JesusAlos: Hi
03:51 AM gloops: morning
04:05 AM gloops: lol https://www.youtube.com/watch?v=jwamJy9chdU
04:05 AM gloops: i wonder why
05:04 AM jthornton: morning
05:05 AM XXCoder: morning
05:25 AM jthornton: Tom_itx: looks like at one point I've tried atom back a couple of years ago... we will see what it's like now
05:25 AM XXCoder: welcome back
05:29 AM jthornton: yea raining here so lost internet
05:31 AM XXCoder: dish?
05:36 AM JesusAlos: There are a planning to create a LCNC lice CD with a newest version?
05:38 AM XXCoder: linuxcnc lice doesnt sound good lol
06:15 AM jdh: speciesist
06:16 AM XXCoder: lol
06:49 AM JesusAlos: XXCoder: What does it mean?
06:50 AM Tom_itx: jthornton, i wound up using snap to install notepadqq
06:51 AM Tom_itx: later..
06:51 AM jthornton: what do you think of notepadqq?
06:51 AM Tom_itx: so far i like it
06:52 AM Tom_itx: haven't spent much time with it though
08:27 AM JT-Shop: so much for todays plans 1 1/2" of rain last night and still raining
08:59 AM Net|: winter is the rainy season ?
09:02 AM mozmck: It is here in TX
09:03 AM mozmck: We got 4 inches overnight a week ago. several inches since then as well.
09:20 AM flyback: https://www.youtube.com/watch?v=Maxf1C68wdo&list=PL3BVzak6Qm5SxkE_S_LOsZg8SKjw_-ZuD
09:20 AM flyback: BMCC
09:24 AM Loetmichel: *OUCHOUCH!* just tried to rivet a quick release screw into a piece of sheet alu... and had the left index finger to close to the rivet. *HAMMER* "OUCH!"... 30 sec later the nail is already turning black... and it DOES hurt quite a bit... maaaan am i daft.. :-(
09:30 AM gloops: bandsaw playing with 9 inch ash log - no problem, onwards and upwards
09:42 AM * veek purrs happily
09:44 AM flyback: https://www.youtube.com/watch?v=-ZO__ebsSpE <--- very impressive
09:44 AM flyback: many many many
09:44 AM flyback: many many many
09:44 AM flyback: hrs of cnc work there
09:46 AM gloops: something good happened veek?
09:46 AM veek: gloops, yeah :)
09:47 AM veek: my cousin dropped in and she said she'd get me some edible bamboo :)
09:48 AM gloops: hmm edible bamboo, only time ive had that is from a chinese takeaway, i wonder if it grows here
09:49 AM veek: ah hmm.. pickled it's yummy
09:49 AM veek: and the culm is edible so.. if you have a greenhouse it could grow and yield
09:50 AM * veek is not an expert in gardening
09:52 AM gloops: well just had a quick google, it does grow here, i dunno how id use it though
09:53 AM gloops: (it doesnt really go with our standard potatoes cabbage and leeks lol)
09:53 AM veek: i use it in the garden.. and i have hopes for making something structural with metal.. some guys made a bamboo bicycle
09:53 AM gloops: bamboo canes are useful yes
09:53 AM gloops: in fact becoming a big thing in flooring now
09:54 AM veek: grows like crazy and sheds leaves all over the place
10:02 AM gloops: leaves are ok for the soil
10:03 AM 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..
10:04 AM Rab: Shallow and deep rooting. It's almost impossible to control.
10:05 AM Rab: Supposedly the only way to stop it from spreading is to dig down .5m and install metal plate.
10:06 AM Rab: Or spend your life digging up the roots.
10:06 AM veek: we have the thorny stuff.. thorns about 12" long and 2D projections - razor sharp
10:08 AM 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.
10:09 AM gloops: hmm, problem plant here is japanese knotweed
10:10 AM 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
10:21 AM Loetmichel: Rab: bamboo grows like weeds, indeed. its a grass after all.
10:21 AM Loetmichel: but its not as bad as those ornamental kudzu stuff.
10:22 AM Loetmichel: you can easily contain it by ripping it out completely before it starts seeding. not that deep roots that you would "forget" something.
10:23 AM SpeedEvil: Or just mowing it
10:23 AM Loetmichel: SpeedEvil: it will come back if mowed
10:23 AM SpeedEvil: Not if you keep doing it.
10:23 AM Loetmichel: also: it needs a pretty sturdy mower.
10:23 AM SpeedEvil: I mean continue to mow it at 1"
10:23 AM Loetmichel: at lest the sorts that grow BIG
10:24 AM Rab: SpeedEvil, you can literally watch it grow. That would be mowing every few hours.
10:24 AM Loetmichel: if you continue to mow it at 1" it will simply be a "sturdy" variant of an english green ;)
10:24 AM Loetmichel: Rab: some sorts yes
10:24 AM SpeedEvil: That's what CNC mowers are for.
10:26 AM Rab: There's a war going on between bamboo sprouts and the floor of my shipping container...I guess CNC mower could be arranged.
10:26 AM Loetmichel: SpeedEvil: that said: a bamboo lawn would be nice... can double up as a wire brush .-)
10:26 AM SpeedEvil: :)
10:26 AM Loetmichel: Rab: let me guess: the container is losing?
10:27 AM Rab: Loetmichel, not yet, but I have an uneasy feeling.
10:28 AM * Loetmichel wouldnt be surprised if a few 100 bamboo sprouts of the right varity can lift the entire shipping container up 100 ft...
10:28 AM 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.
10:28 AM Loetmichel: ... just by growing ;9
10:33 AM roycroft: seedlings?
10:33 AM roycroft: if they're bamboo that is exceedingly rare
10:33 AM SpeedEvil: seedlings is the wrong term
10:33 AM roycroft: bamboo plants flower once, then die
10:34 AM roycroft: and they usually live about 75-100 years before they flower
10:34 AM SpeedEvil: (for vegatative outgrowths of the main clump for propagation)
10:34 AM roycroft: they almost always "reproduce" by sending runners underground
10:35 AM mozmck: rhizomes
10:35 AM roycroft: yes
10:35 AM SpeedEvil: ^
10:35 AM roycroft: and they do that once/year - in mid spring
10:35 AM SpeedEvil: I thought that, but thought I might be wrong.
10:35 AM mozmck: I have probably 15 varieties of bamboo on my place
10:35 AM roycroft: but when they do, you can literally watch them grow
10:36 AM Rab: roycroft, my mistake, rhizomes.
10:36 AM mozmck: Yeah, I've measured some grow about 2' per day
10:36 AM SpeedEvil: Just two here (scotland). I'd guess 5m tall.
10:36 AM roycroft: a shoot can grow 10m over the course of a few days once the sprout emerges
10:37 AM Loetmichel: IIRC there are some types of bamboo that can grow 30m++ in a single summer
10:37 AM SpeedEvil: If you disconnect isolated parts of the clump at the edge, do they still die at the same time?
10:37 AM gloops: whats the nutritional value
10:37 AM roycroft: they don't do that, loetmichel
10:37 AM roycroft: they do all their growing at once
10:37 AM roycroft: over a week or two
10:37 AM gloops: i mean, im all for these crops you just stick and forget about
10:37 AM roycroft: then they are done growing forever
10:37 AM gloops: if they are worth eating...
10:37 AM Loetmichel: roycroft: s/summer/season
10:37 AM roycroft: the young, tender shoots are edible
10:37 AM SpeedEvil: gloops: you have to process them to make them edible.
10:38 AM SpeedEvil: gloops: On the plus side though - pandas are delicious.
10:38 AM roycroft: but after they start growing they're not
10:38 AM roycroft: you have to cut them when they first emerge to eat them
10:39 AM * roycroft grows bamboo as a screening plant, as there are some two story townhouses right behind his back yard
10:39 AM mozmck: some bamboo shoots are edible without processing.
10:39 AM roycroft: they do not need to be processed
10:39 AM roycroft: they just need to be harvested as they emerge
10:39 AM roycroft: wait a day and it's too late
10:39 AM SpeedEvil: roycroft: I've wondered about fake bamboo clumps for screening - have containers with 60cm bamboo growing out the side, and stack em
10:40 AM veek: and soak them in water.. to remove toxins
10:40 AM mozmck: Some are bitter I think. I have varieties which are sweeter.
10:40 AM roycroft: i don't eat mine
10:40 AM mozmck: I have, but there is almost no nutrition in bamboo shoots.
10:40 AM gloops: hmm seems they have some nutritional value, vitamins and minerals, very low calories, high fibre
10:40 AM roycroft: bamboo can also be pretty useful as "lumber"
10:41 AM gloops: so, youve got a bamboo bush - do you get canes, like garden canes you buy in the shops?
10:41 AM mozmck: yeah, I have a forest of vivax and dulcis - both timber stuff.
10:42 AM mozmck: smaller varieties make the smaller canes you buy in the shops.
10:42 AM gloops: hmm, i might stick a few plants in this year
10:42 AM roycroft: bamboo is expensive
10:42 AM mozmck: I need to find someone to sell some of mine to then!
10:42 AM gloops: i notice its getting popular for flooring
10:43 AM roycroft: but if you get the spreading kind you can plant them pretty far apart and just wait a couple years
10:43 AM roycroft: if you get the clumping kind you have to buy a lot if you want a solid screen
10:43 AM roycroft: i don't grow clumping bamboo, but i'm told it can be divided successfully
10:44 AM roycroft: that's probably how it's commercially produced, since it only seeds once
10:44 AM roycroft: i'm sure not all clumping bamboo is wild harvested
10:44 AM gloops: ill have to check out the different varieties that grow here and what theyre good for
10:45 AM roycroft: bamboo is great for privacy screens
10:46 AM mozmck: gloops: I think the main thing you'll have to look for is cold hardiness
10:47 AM gloops: yeah needs to be hardy, looks like there are quite a few that do survive here though
10:47 AM mozmck: How cold does it get there?
10:48 AM veek: https://www.ncbi.nlm.nih.gov/pubmed/21972937 'mass cyanide poisoning from pickling bamboo shoots'
10:49 AM gloops: it might get down to -10 rarely lower
10:49 AM gloops: -10C
10:50 AM gloops: looks like they were in the bamboo pickling pit though veek
10:51 AM veek: yep
10:52 AM veek: it contains toxins that are destroyed when heated
10:53 AM veek: same as cassava 'cyanogenic glycoside, in fresh bamboo shoots may lead to food poisoning when consumed'
11:01 AM roycroft: it got to -23 here three years ago and my bamboo did not die
11:01 AM roycroft: that, btw, was the lowest temperature ever recorded here
11:01 AM SpeedEvil: -15C I think here a couple years ago.
11:01 AM SpeedEvil: might have been three.
11:02 AM roycroft: most years -6 or so is the coldest we get
11:02 AM roycroft: ours is a fairly maritime climate
11:02 AM roycroft: tempered by the coast range a bit
11:06 AM Simonious: hat do solidworks call it when they model a part around an existing part? I call it scaffolding.
11:06 AM Simonious: *What
12:24 PM * gloops admiring first log slices off diy bandsaw
12:26 PM fragalot: gloops: but did it actually happen?
12:27 PM gloops: yes
12:27 PM * fragalot doesn't believe you :-)
12:27 PM * jthornton waits for the photos...
12:27 PM gloops: i might make a quick vid tommorrow
12:28 PM fragalot: so it hasn't happened yet but you're working on it. gotcha.
12:28 PM gloops: you cant laugh at its rudimentary construction - not now it is proven to work lol
12:29 PM 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...
12:29 PM fragalot: Aye
12:32 PM 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
12:33 PM gloops: why i would build a saw to make those i cant think, but it is a useful thing, lot of applications here
12:47 PM fragalot: oh dear
12:47 PM fragalot: my order on the belgian digikey has been shipped from the US
12:47 PM * fragalot braces for import duties
12:48 PM * FinboySlick yells "INCOMING!" holds his helmet and ducks in a trench.
12:52 PM * gloops ejects the warp core
12:52 PM fragalot: lol
01:02 PM roycroft: i'm thinking about making my new workbench out of ash
01:03 PM roycroft: i really like the one that matt estlea made
01:05 PM Jymmm: lot of ash here, all you want for free
01:06 PM roycroft: i need a couple hundred board feet for the bench
01:07 PM FinboySlick: roycroft: Wood workbench?
01:07 PM cpresser: afaik digikey takes care of all duties
01:07 PM roycroft: it would be worth the trip down there for some free ash
01:07 PM roycroft: yes, finboyslick
01:09 PM FinboySlick: If I ever have a chance, I'd probably make a Roubo style workbench. They're pretty darn great.
01:11 PM gloops: ash boards are not so common here, but ash is strangely enough
01:11 PM FinboySlick: https://www.youtube.com/watch?v=3pfm6URciYc Here's a terrible infomercial-style video about 'em.
01:16 PM FinboySlick: I'm pretty sure plans for this one are freely available somewhere.
01:16 PM roycroft: that is my plan, finboyslick
01:17 PM roycroft: i really like roubo benches
01:17 PM roycroft: the only downside is that the good roubo vise hardware is really expensive
01:17 PM roycroft: the stuff made by benchcrafted
01:18 PM roycroft: US$1200
01:18 PM roycroft: http://www.leevalley.com/en/wood/page.aspx?p=70361&cat=1,41637,41659
01:19 PM FinboySlick: roycroft: Well, I'm sure a bit of patience on a lathe could get you something pretty similar.
01:19 PM roycroft: https://www.youtube.com/watch?v=FXKYwM0f5WU
01:20 PM roycroft: there's matt's, done in ash with that same vise hardware
01:20 PM roycroft: i was going to use beech, which is pretty traditional for a workbench, but i really like his ash one
01:22 PM FinboySlick: roycroft: Ah, yes. I watched all of that video too when I discovered Roubo workbenches.
01:22 PM roycroft: if i could find some nice cast wheels similar to the benchcrafted ones, i'd make the rest of the hardware
01:22 PM roycroft: matt's a very talented lad
01:23 PM 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
01:23 PM FinboySlick: roycroft: Take a page from Tom Lipton's baby bullet videos.
01:24 PM roycroft: i have a cheap bench currently, without a face vise and with a crappy tail vise
01:24 PM fragalot: those videos were godlike
01:24 PM roycroft: i built a stanton bench which is really useful for assembly and for sanding/planing things horizontally
01:25 PM FinboySlick: Semi-decent welds, good files and patience can get you pretty good 'castings'.
01:25 PM roycroft: i'm starting to build some cabinets now, but when those ar done i want to work on a new woodworking bench
01:59 PM gloops: thats like a blacksmiths vice
01:59 PM gloops: - leg vice
02:01 PM gloops: https://www.ebay.co.uk/itm/Blacksmiths-farriers-vintage-leg-vice-no-fixing-bracket-will-post/113495673370?
02:39 PM gloops: well thats a few thousand photos saved of designs i want to make, just got to draw them all and make gcode lol
02:45 PM JT-Shop: I made a roll around cabinet out of scraps for the Tormek http://gnipsel.com/images/equipment/tormek/
02:48 PM fragalot: how are you liking that tormek
02:50 PM JT-Shop2: so far it does a good job on anything I've sharpened
02:50 PM mozmck: I've been thinking about getting a Rikon - tormek is too expensive
02:50 PM gloops: looks a useful arrangement
02:50 PM JT-Shop2: I got this one used for cheap with a ton of accessories
02:50 PM JT-Shop2: need to make some drawers next for it
03:16 PM Tom_itx: doesn't look like there's room for any drawers
03:24 PM Tom_itx is now known as Tom_L
03:33 PM elmo40: always room for drawers
03:34 PM jthornton: and fun to learn how to make them...
03:50 PM Deejay: gn8
03:56 PM rmu: https://www.nist.gov/
03:57 PM rmu: ridiculous
04:13 PM rmu: https://de.aliexpress.com/item/IRF4905-power-MOSFET-55V-74A-200W-Absolutely-authentic-fake-a-penalty-ten-please-rest-assured/32226886998.html
04:14 PM rmu: nach alternativen fakten, fake news jetzt authentic fakes!
04:15 PM XXCoder: wow. a authentic fakies. havent seen those for a while. only can find fake fakies
06:31 PM Vitran: Odd issue. Hoping someone may know what is happening here. https://i.imgur.com/fkqPV5v.png
06:31 PM Vitran: The rps is working, but the rpm is not
06:31 PM roycroft: so my digital caliper finally arrived
06:31 PM roycroft: it was sold as "new, with damage to the packaging"
06:31 PM XXCoder: hows it roycroft
06:31 PM roycroft: i thought that meant that the case might be cracked or something
06:31 PM roycroft: but no
06:32 PM roycroft: it is the outer amazon-provided package that was damaged
06:32 PM roycroft: what came from mitutoyo was in perfect condition
06:32 PM roycroft: and i like it
06:32 PM XXCoder: lol so case and caliper is perfect
06:32 PM XXCoder: nice
06:32 PM roycroft: it has a nice balance, and is very accurate
06:32 PM roycroft: yeah
06:32 PM XXCoder: how about repeatability?
06:32 PM roycroft: $93 for it
06:32 PM roycroft: it's quite repeatable
06:33 PM XXCoder: ie go out and in few times, and measure again
06:33 PM roycroft: assuming the operator is consistent
06:33 PM roycroft: i'll have to go measure some gage blocks in a while
06:34 PM XXCoder: use rod to measure inner to outmost
06:34 PM roycroft: and it measures to 0.01mm/0.0005in
06:34 PM roycroft: a factor of two better than any other caliper i have
06:34 PM roycroft: yeah, i should do that
06:34 PM XXCoder: my first mitoyoto caliper was bit damaged by drop so it has .0005" difference insidemost to outmost blades
06:34 PM andypugh: Vitran:
06:34 PM roycroft: i have some telescoping gages
06:34 PM andypugh: Still there?
06:34 PM XXCoder: it got certified still but good to know
06:34 PM Vitran: yep
06:35 PM andypugh: You are looking at signals, not pins
06:35 PM XXCoder: hey andypugh hows things
06:35 PM andypugh: I guess that the rps feedback is straight from an encoder?
06:35 PM Vitran: yes
06:36 PM Vitran: As is, it is spinning up to max RPM on a PID of 1,0,0
06:36 PM andypugh: You probbaly want to run the PID on RPS both sides
06:37 PM andypugh: You can pretty much ignore RPM, except if you want an rpm display. And if you have PID and trust it, why bother?
06:37 PM pcw_mesa: The other way is to scale the feedback (60X) so you get feedback RPM for a meter etc
06:38 PM andypugh: Indeed, but frankly I don’t see the need
06:38 PM pcw_mesa: but Andys way is simpler for a start
06:38 PM Vitran_: Sorry, internet over X10 isn't that good.
06:38 PM Vitran_: So should I change the RPM to RPS in the .hal file?
06:38 PM 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..
06:39 PM pcw_mesa: also best to tune 0,0,0 FF0=1 == open loop to verify that every thing else is OK
06:40 PM 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
06:41 PM 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.
06:41 PM Vitran_: I think I am also having issues with the Output Scale number.
06:41 PM andypugh: That should probably be peak speed, but also needs to be scaled in RPS or RPM, for consistency
06:42 PM Vitran_: It is a 0-10V range, 4000rpm max. So I thought that the output scale would be 10/4000 = 0.0025
06:42 PM andypugh: No, should prpbably be 5000 rpm / 60 s
06:43 PM Vitran_: I was basing that number off of this http://linuxcnc.org/docs/html/examples/spindle.html
06:44 PM andypugh: Well, I am just guessing. What is the hardware?
06:45 PM Vitran_: Hardinge Superslant. It has an old Siemens spindle drive
06:45 PM Vitran_: The spindle drive has a tachogenerator feedback to itself
06:45 PM Vitran_: and the 7i77 has an encoder linked to it
06:45 PM andypugh: For a 7i77 you want scalemax to match the command and feedback max in the same units
06:47 PM Vitran_: Max is +-10 https://imgur.com/TY3jeTf
06:47 PM 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
06:48 PM andypugh: net pid.s.feedback to spindle-vel-fb-rps instead
06:49 PM andypugh: And set the INI scales all to +/- 83.33
06:49 PM Vitran_: What about spindle-vel-cmd-rpm => pid.s.command?
06:49 PM andypugh: set that to rps too
06:50 PM Vitran_: Am I setting the Output_Min_Limit to 83.33?
06:50 PM andypugh: We can’t tell from what is visible there, but I suspect that the feedback-rpm is just never linked
06:50 PM andypugh: Min lim probably wants to be -83.33. Or possiobly zero.
06:51 PM andypugh: Are you running the VFD +/- 10V or 0=10V + DIR?
06:51 PM Vitran_: +-10V
06:52 PM andypugh: OK, then definitely -83.33
06:53 PM Vitran_: It currently spins at~10rps, output voltage of .01666666V, Spindle-Vel-cmd-rps of 0.0166666
06:53 PM Vitran_: ah, problem
06:54 PM Vitran_: At higher rpm, the encoder is having issues
06:54 PM andypugh: That’s at S1?
06:54 PM Vitran_: That is at S1
06:54 PM Vitran_: Or, the parameters indicated?
06:54 PM andypugh: It’s possible that the VFD has a minumum frequency. It probably should have
06:55 PM andypugh: You might need to turn off the spindle encoder filter. PCW?
06:55 PM Vitran_: https://i.imgur.com/BtoAlrS.png
06:56 PM Vitran_: the HAL configruation, teh Spindle-vel-fb-rps keeps on dissapearing to 0
06:56 PM andypugh: What happens at actual practical spindle speeds?
06:56 PM Vitran_: As is, the Spindle-vel-fb-rps is showing 0
06:57 PM andypugh: You are unlikely to be doing much work at 2 rpm…
06:57 PM Vitran_: Right now it is doing 2000rpm
06:57 PM SpeedEvil: andypugh: machine settings for when you don't want it to wake you up
06:57 PM andypugh: Hmmm, is the spindle encoder scale ever being set?
06:58 PM Vitran_: On the encoder it wrote 5000
06:58 PM Vitran_: I was doing tests where I counted the rps of the encoder and back calculated it to find the scale
06:58 PM Vitran_: *there was a note on the encoder that it had 5000
06:58 PM andypugh: And the spindle is on encoder 0 and analogout 5?
06:59 PM Vitran_: https://i.imgur.com/pTnssnk.jpg
06:59 PM Vitran_: uh, yeah. That was because I first had the spindle on alaogout 0
06:59 PM Vitran_: But then I learned that analogout 5 had a seperate enable pin
06:59 PM andypugh: It’s not a problem, just checking
07:00 PM andypugh: If the spindle is _actually_ doing 2000 rpm and the spindle feedback is 0.125 rps then something, somewhere, is a bit wrong
07:00 PM andypugh: But I see that you have ignored our advice about FF0, P, I and S
07:00 PM andypugh: (D)
07:00 PM Vitran_: ?
07:01 PM Vitran_: Sorry, what did I miss? I did a PID of 0,0,0,1
07:01 PM andypugh: Sorry, I was reading the wrong section. My mistake
07:02 PM andypugh: OUTPUT_SCALE needs to be 83.33
07:03 PM Vitran_: How did you find that number? Could that be added to the Spindle Drive tutorial that I linked above?
07:06 PM andypugh: 83.33 is your max spindle speed in RPS…
07:06 PM Vitran_: Ah. I see.
07:08 PM Vitran_: As is, I can get it up to 17rps/1020rpm using the +- dials below the spindle control
07:08 PM Vitran_: It does not seem to allow me to go faster, but likely some limit I set
07:09 PM Vitran_: It was. Max_output was set to 9
07:10 PM 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.
07:11 PM Vitran_: I see the encoder stops reading when going faster than 900 rpm. I can make it go faster, but the encoder stops reading
07:11 PM 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)
07:12 PM andypugh: You might need to turn of the encoder counter filter
07:12 PM andypugh: PCW can tell you how, I expect. I need to sleep.
07:12 PM andypugh: (Goodnight all)
07:13 PM Vitran_: Thanks, night.
07:36 PM Vitran_: I disabled the counter filter which allows me to go up to 30rps/1800rpm. Half way there, which is good
07:37 PM Vitran_: Looks like I need a different encoder
07:37 PM Vitran_: Anyways, night all

10:15 PM norias: what's funny about that?
10:16 PM XXCoder: just surpised theres one now
10:16 PM norias: i feel like i'm missing something
10:16 PM XXCoder: quite a while ago I looked for em didnt find any
10:17 PM norias: ahh, ok
10:18 PM norias: ugh
10:18 PM norias: my brain needs a day off
10:18 PM XXCoder: weird. if I search for Indicator Light CNC theres no result besides very exensive option
10:18 PM norias: huh
10:19 PM Wolf__: search for tower light
10:19 PM XXCoder: oh better terms yeah
10:19 PM XXCoder: way more results

10:21 PM XXCoder: discription has nothing cnc in it lol
10:21 PM XXCoder: road and stuff
10:21 PM Wolf__: for most things I end up looking for a google image that leads back to ali and then use part of the name to find more options lol
10:22 PM XXCoder: not bad idea yeah
10:22 PM XXCoder: what did we expect from website that has "3d printer milling lathe engraver" as discription for 3d printer
10:24 PM Wolf__: lol
10:24 PM XXCoder: check out name https://www.aliexpress.com/item/Mini-CNC-router-1010-frame-column-type-engraving-machine-400W-spindle-Vertical-3axis/32959163645.html
10:25 PM Wolf__: seems right…
10:25 PM XXCoder: junk really but maybe good for student or something lol
10:25 PM Wolf__: probably haha

10:26 PM XXCoder: great intro to cnc, can be kits students has to build and tune
10:26 PM XXCoder: learn heck of a lot about how to get precision
10:28 PM Wolf__: I expect that my plasma machine is going to totally suck lol
10:28 PM XXCoder: passing grade for class: success on circled diamond square
10:30 PM Wolf__: 264 ipm/ 6706 mm/min might be interesting to see that machine I’m building try to do
10:31 PM XXCoder: interesting. adding "vertical" makes it way easier to find actual mills in aliexpress
10:32 PM XXCoder: mills still very uncommon so expensive still
10:38 PM Wolf__: 5359mm/min 8mm per turn on the screw, so 670 rpm on a 1.5m long 8mm dia screw might not be too terrible
