12:42 AM lcnc-relay: <pink_vampire@> So, some good news, my stuff are here!! (in parts right now)
12:57 AM lcnc-relay: And it is such a happy moment to get myself back in to the cnc stuff.
12:57 AM lcnc-relay: The small CNC that I want to convert to a larger one is the 12"x12" made by "inventables"
12:57 AM lcnc-relay: The rails are integrated in to 5he aluminum extrusions and there are V groove bearings that ride on them.
12:57 AM lcnc-relay: Sadly I can't find much information about this type of railing system.
12:57 AM xxcoder: x-carve?
12:57 AM xxcoder: such expensive machine wow
12:57 AM xxcoder: ones being sold now is MGN rail type
01:10 AM Deejay: moin
04:16 AM lcnc-relay: <travis_farmer@> Morning
04:56 AM Tom_L: morning
05:27 AM lcnc-relay: <.le_potato@> morning
06:30 AM lcnc-relay: <.le_potato@> anybody did robot control with linuxcnc or doesnt support it?
06:30 AM lcnc-relay: <.le_potato@> i have a few 6 axis epson robot
06:30 AM lcnc-relay: <.le_potato@> without controller :/
06:34 AM lcnc-relay: <.le_potato@> i see source for it but im not sure how is it alpha/beta
07:31 AM Tom_L: http://linuxcnc.org/docs/stable/html/motion/kinematics.html
07:51 AM lcnc-relay: <pink_vampire@> xxcoder: Yeah, it is the one of their first machines. Maybe even before they came up with the "X Carve" name..
07:51 AM lcnc-relay: I would love to convert it to something like MGN rails.
07:51 AM lcnc-relay: Do you have a guide / video how to do it?
08:01 AM lcnc-relay: <.le_potato@> Tom_L i seen this somehow it doesn't work in practice based on the information on the internet
08:02 AM jpa-: works for me
08:02 AM jpa-: (of course individual kinematics drivers can be broken)
08:02 AM rdtsc: someone recently here converted an Epson to linuxcnc, or started on it anyways (hmm wonder where they've been)
08:44 AM lcnc-relay: <pink_vampire@> I think this are the rails that my cnc is using. If you look at the picture you will see the part that the V groove bearings are riding on:
08:44 AM lcnc-relay: https://www.inventables.com/products/makerslide-black-anodize-5m-tapped?variant=41033539977273
09:18 AM rdtsc: generally in my experience, https://www.ebay.com/itm/226749251756 et.al. is the next step up in "linear rail", followed by https://www.ebay.com/itm/166134727967, then followed by ("real" and expensive) name-brand rails, in terms of precision and effectiveness - ultimate accuracy is an ever-deepening hole which never ends
09:19 AM lcnc-relay: <pink_vampire@> Which endmill is recommended for 2D operation on partical board?
09:31 AM lcnc-relay: <pink_vampire@> rdtsc: I don't like the idea of unsupported round rails like the SFC16.
09:31 AM lcnc-relay: I want to basically use as much of the original machine.
09:31 AM lcnc-relay: I like the belt drive mechanism, and I want to reuse it by but with longer belt.
09:31 AM lcnc-relay: I want to be able to fit 36" X 48" plate in the machine. So I need to add abit more to that for the rail.
09:31 AM lcnc-relay: ... long message truncated: https://jauriarts.org/_heisenbridge/media/jauriarts.org/fcMBUrTNGeCkcEhvMIbqiTxZ/zutITTz116E (6 lines)
09:57 AM lcnc-relay: <.le_potato@> and yeah, i stay on axis, its getting complicated on that, lol
10:03 AM Tom_L: best of luck with gmocrappy or qtdragon
10:04 AM Tom_L: le_potato, if you want an alternate gui you should look into flexgui and roll your own
10:05 AM Tom_L: there are several examples to start from
10:06 AM Tom_L: even an axis lookalike
10:17 AM lcnc-relay: <.le_potato@> i go with flexgui
10:17 AM lcnc-relay: <.le_potato@> but atm axis can handle me
10:17 AM Tom_L: can you handle it?
10:17 AM Tom_L: :)
10:17 AM JT-Shop: :)
10:20 AM Tom_L: mowed before it got _too_ hot
10:21 AM roycroft: it is overcast here today
10:21 AM JT-Shop: it started out too hot here
10:21 AM JT-Shop: anyone using master?
10:21 AM roycroft: no chance of rain though
10:21 AM Tom_L: it's hot but wasn't too hot
10:21 AM Tom_L: not me
10:22 AM roycroft: but it's going to cool off significantly
10:22 AM Tom_L: and i haven't tried building one in quite a while
10:22 AM JT-Shop: not here
10:23 AM JT-Shop: http://linuxcnc.org/docs/stable/html/config/ini-config.html#sub:ini:sec:spindle-num
10:23 AM JT-Shop: the docs say those settings are for the motion controller but they don't do anything that I can see
10:23 AM Tom_L: saw your note in devel
10:24 AM JT-Shop: setting MAX_FORWARD_VELOCITY = 100 and you can s50000m3 and it sets the spindle to 50000
10:28 AM Tom_L: By default maximum velocity of the spindle in forward and reverse is approximately 2147483000 RPM
10:29 AM Tom_L: that's a ridiculous number
10:30 AM Tom_L: not even sure there's a device made to spin that fast
10:33 AM roycroft: that is close to 2^31
10:48 AM lcnc-relay: <skunkworks8841@> hmm - I need to make up some dies for the hydraulic press
10:49 AM Tom_L: steel dies?
10:49 AM Tom_L: for what?
10:50 AM lcnc-relay: <skunkworks8841@> ah - what are they called - like a V to bend flats
10:50 AM Tom_L: oh
10:50 AM lcnc-relay: <skunkworks8841@> I need to make some right angles
10:50 AM lcnc-relay: <skunkworks8841@> and 45's
10:50 AM lcnc-relay: <skunkworks8841@> I have a wedge - but need the v
10:50 AM Tom_L: i asked because we used to make stamp dies for sheet
10:50 AM Tom_L: flame hardened the edge
10:50 AM lcnc-relay: <skunkworks8841@> we have made a whole of 1 punch press die..
10:51 AM lcnc-relay: <skunkworks8841@> I wonder were that is...
10:51 AM lcnc-relay: <skunkworks8841@> it has to be around here somewere
10:51 AM Tom_L: i think i mentioned them the other day
10:51 AM Tom_L: along with hydro press forms
10:52 AM Tom_L: used cork inside to pop the sheet out
10:53 AM roycroft: i need to make some punch press dies at some point
10:53 AM roycroft: i don't have a punch press per se, but i have a 12 ton hydraulic press that i am going to fit with plates to turn it into an effective punch press
10:54 AM roycroft: one can purchase metal strips that are pre-sharpened for making dies
10:54 AM lcnc-relay: <skunkworks8841@> actually 2 dies.. I am prettys sure I made one to do these slots in aluminum..
10:54 AM lcnc-relay: <skunkworks8841@> https://photos.app.goo.gl/NeGAhjpWGD71dawa8
10:55 AM lcnc-relay: <skunkworks8841@> and I wonder were that is too lol
10:55 AM * roycroft would be cutting leather, not metal with the dies
10:55 AM Tom_L: these were specific shapes so the edge was hardened after machining
10:56 AM roycroft: yes, tom_l, the strips i'm talking about are pre-sharpened, but they edges need to be hardened after they're formed into dies
10:56 AM Tom_L: i bet if i look i could find the cnc files....
10:56 AM Tom_L: maybe
10:56 AM roycroft: if they were pre-hardened the edges would crack when bending them into the die shape
10:56 AM Tom_L: most were digitized from old mylars
10:56 AM Tom_L: i doubt if kids even know what those are nowdays
10:57 AM * roycroft just finished his cappuccino, and thinks it's time to build the shelves in his office closet
10:57 AM lcnc-relay: <skunkworks8841@> lol.. dad used to have a microfish reader that would print on blueprint style paper
10:57 AM roycroft: i've been putting a lot of time into the cnc controller cabinet this past week, and i need to get other things done
10:57 AM lcnc-relay: <skunkworks8841@> the thing was huge - don't think we ever used it
11:00 AM Tom_L: huge seems to be the norm around your place
11:00 AM lcnc-relay: <skunkworks8841@> lol
11:00 AM lcnc-relay: <skunkworks8841@> probably
11:00 AM lcnc-relay: <skunkworks8841@> Tom_L: the die would be flame hardened?
11:01 AM Tom_L: yeah we used a torch around the edge and followed with a wet rag
11:01 AM Tom_L: it worked
11:01 AM lcnc-relay: <skunkworks8841@> neat - the monarch lathe ways are flame hardened
11:01 AM Tom_L: you'd kinda get a feel for how fast to move with both
11:02 AM lcnc-relay: <skunkworks8841@> I bet
11:04 AM Tom_L: it wasn't an exact science :)
11:04 AM lcnc-relay: <skunkworks8841@> but probably worked just fine
11:04 AM Tom_L: it was stamping aluminum anyway
11:05 AM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/Mill_Steel/Boxes.jpg
11:05 AM Tom_L: those were likely hydroformed
11:06 AM Tom_L: generally those were sheetmetal for aircraft that wasn't critical
11:06 AM Tom_L: and the forms had like a 2.5deg undercut for springback
11:06 AM Tom_L: ^^ that's where the box for my pendant came from :)
11:08 AM lcnc-relay: <skunkworks8841@> nneat
11:34 AM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/ballast.jpg
11:34 AM Tom_L: trailing edge lead wing ballast parts
11:35 AM Tom_L: if it was a real tight space they were tungsten
11:56 AM JT-Shop: now that I have some #10 3/8" ring terminals I can start rewiring the hoe
12:01 PM JT-Shop: but first a nap
12:18 PM xxcoder: good morning
12:21 PM lcnc-relay: <xxcoder@> pink_vampire@: hard to say honestly. just swapping those wheels/rail with MGN seems easiest, but not sure how you would retrofit it in without replacing some parts, like side plates
12:29 PM roycroft: i was about to complain about having taken a tool i need for this project back to storage and having to drive over there to get it
12:29 PM roycroft: but on the way back my car turned into the bakery parking lot somehow, and they had a delicious smoked salmon brioche
12:30 PM roycroft: so i guess retrieving that tool was meant to be for other reasons
12:30 PM roycroft: and yeah, this is a tiny town with virtually no services, but we have an amazing bakery
12:33 PM rdtsc: "fast food capitol of the world" with literally a hundred restaurants here, and no salmon brioche anywhere to be seen... except for maybe an exorbitant price tag :)
12:45 PM Tom_L: nap sounds like a pretty good idea
12:47 PM lcnc-relay: <skunkworks8841@> https://photos.app.goo.gl/AZZDhZv9szXB7GDp8
12:49 PM Tom_L: looks like it works
12:50 PM lcnc-relay: <skunkworks8841@> I think I need to replace the consumables..
12:50 PM lcnc-relay: <skunkworks8841@> but I don't remember the last time I did that 😉
12:51 PM Tom_L: does that work harden the edge if you had to machine it any?
12:51 PM Tom_L: i bet it does some
12:52 PM lcnc-relay: <skunkworks8841@> https://photos.app.goo.gl/cG7BNeUDiPRgaZhE8
12:55 PM lcnc-relay: <skunkworks8841@> I would assume a little...
12:55 PM lcnc-relay: <skunkworks8841@> (hardening)
01:45 PM JT-Shop: time to trap a coon
01:47 PM Tom_L: is that what got the deere?
01:49 PM JT-Shop: no, one was just on the deck eating out of the bird feeders
01:50 PM Tom_L: uh oh
02:08 PM JT-Shop: as long as they stay off the deck I don't bother them, but once they find the deck it's game on
02:10 PM lcnc-relay: <.le_potato@> Tom_L, im fs wizard max rpm is 10k :/
02:10 PM lcnc-relay: <.le_potato@> *in
02:11 PM Tom_L: can't edit that?
02:12 PM lcnc-relay: <.le_potato@> no
02:13 PM roycroft: i have two big shelves in my office closet that were not there earlier today!
02:13 PM * roycroft also has plenty of stuff to load on them
02:13 PM xxcoder: ghoooosts
02:14 PM Tom_L: le_potato, i just entered 12000 rpm
02:14 PM roycroft: w'
02:14 PM roycroft: ;
02:14 PM Tom_L: then 24000 rpm
02:15 PM roycroft: are you working on entering the twilight zone?
02:15 PM Tom_L: no
02:15 PM Tom_L: actually at my kid's work they have some 30000 rpm spindles
02:15 PM roycroft: too bad - i hear it's a groovy place to be
02:16 PM Tom_L: feeds 2-400ipm or more
02:17 PM xxcoder: I had set it to 12000 rpm, it reset to 10,000 rpm max
02:17 PM Tom_L: le_potato, select 6061 T6 aluminum for a material and see if that matters
02:17 PM Tom_L: i have it on my phone
02:17 PM Tom_L: not the website one
02:18 PM xxcoder: website might be capped to 10k
02:18 PM xxcoder: tried various materials, all capped to 10k rpm
02:19 PM Tom_L: i just entered 24000 rpm on the website and it didn't reset
02:20 PM Tom_L: max 24000 regular rpm 20000
02:20 PM Tom_L: works just fine
02:20 PM xxcoder: oh!
02:20 PM Tom_L: 20000 rpm 1200 ipm chip load .020
02:20 PM xxcoder: found max rpm setting near bottom of page
02:21 PM Tom_L: which is quite too much
02:21 PM Tom_L: read the fine print :)
02:21 PM xxcoder: yep it works, selected 24000 randomly after setting max rpm as 100000
02:22 PM xxcoder: potato you would need to find max rpm near bottom of page. hidden in fold
02:23 PM Tom_L: if you register you might be able to save your tool settings on their cloud. i've never done that
02:23 PM Tom_L: still a pretty decent tool
02:23 PM xxcoder: indeed
02:39 PM JT-Shop: LG says my check is in the mail...
02:39 PM Tom_L: i've heard that line before
02:45 PM lcnc-relay: <skunkworks8841@> I am going to have to make those brackets as weldments. probably be easier to weld than bend
03:04 PM * JT-Shop is somewhat stumped, hooking up all the original wires to the key switch and the starter and with the battery tender on the gen light comes on as it should and once I got one click from the solenoid and the gen light went out
03:04 PM JT-Shop: hooked up the 2500a jumper battery and nothing...
03:05 PM JT-Shop: I guess it wrestle time with the wrong battery (it's a large 12v battery and it should have 2 half large 6v batteries)
03:09 PM lcnc-relay: <skunkworks8841@> the ford tractor has had a car battery in it for as long as I can remember.. Dad made a wood bracket to hold it in the oversized tray
03:30 PM roycroft: all the boxes in my office are unpacked, and only one of the shelves is full
03:30 PM * roycroft thinks there are a few more boxes of office stuff in storage, though
03:31 PM xxcoder: too much shelf space is always better than not enough
03:31 PM xxcoder: former problem evenually solves itself
03:31 PM xxcoder: latter wont
03:32 PM roycroft: i threw away/recycled about 1/3 of what was in the boxes
03:32 PM roycroft: and i anticpate doing that for most of my boxes
03:33 PM roycroft: i figure that if i can get all the boxes that are at the house now unpacked, hauling a few boxes/week over from storage will be pretty easy to manage
03:50 PM Unterhaus_ is now known as Unterhausen
03:51 PM JT-Shop: what makes no sense is when I put the jumper thingy on I get nothing when I try and start it
03:56 PM Tom_L: did you change out the solenoid or determine the old one was good?
03:57 PM Tom_L: and you tested the starter motor itself on the bench iirc
04:02 PM NetPipe: https://github.com/user-attachments/files/21337808/dxfplotter.app.zip
04:03 PM NetPipe: https://github.com/panzergame/dxfplotter.
04:03 PM NetPipe: https://github.com/panzergame/dxfplotter
04:08 PM JT-Shop: tested the solenoid and starter on the bench and it spun so fast it flipped over
04:09 PM Tom_L: something isn't rubbing that shorts when the solenoid engages?
04:09 PM Tom_L: really an odd one
04:10 PM Tom_L: what about that safety lockout circuit?
04:14 PM JT-Shop: if that was the issue I'd never get the click
04:14 PM JT-Shop: right now the gen light won't even come on...
04:14 PM Tom_L: hmm
04:24 PM rdtsc: tap the starter gently?
04:24 PM JT-Shop: starter works so well it scared the crap out of me when I tested on the bench
04:25 PM rdtsc: any mouse houses decide to make spaghetti of wiring?
04:26 PM rdtsc: hopefully just a loose connector
04:26 PM JT-Shop: not that I can see... but oddly enough a while ago the gen light came on and I got one click from the solenoid but nothing since
04:26 PM JT-Shop: there's only 5 wires on the hoe
04:27 PM Tom_L: gen is good?
04:27 PM JT-Shop: now if a wood rat chewed the + cable in two but left them touching...
04:27 PM JT-Shop: it has an alternator
04:27 PM JT-Shop: but that's not in the start circuit
04:27 PM Tom_L: no bad cells in the battery
04:27 PM rdtsc: prolly a raccoon in there trying to hotwire it
04:27 PM JT-Shop: no idea
04:28 PM Tom_L: put a meter on the battery when you try to start it and see how much drop you get
04:28 PM JT-Shop: we have a new resident coon for a short while
04:28 PM Tom_L: that would indicate a short or a bad cell
04:28 PM JT-Shop: right now I get nothing at all
04:28 PM JT-Shop: no light, no click
04:28 PM Tom_L: put the meter on the solenoid coil lead and see what it's doing
04:29 PM Tom_L: then follow that back to the switch
04:29 PM rdtsc: I'm betting his signal wire is intermittent/chewed
04:29 PM Tom_L: i thought he replaced it
04:29 PM rdtsc: but if no gen light, then may be the whole power wire
04:30 PM rdtsc: have seen them get all corroded at an end and look ok but work poorly
04:30 PM Tom_L: and no schematic available
04:31 PM rdtsc: just don't set your wrench on a B+ lead... funny the things we've seen :)
04:35 PM rdtsc: starting high school, the bus stop was next to a convenience store. one warm sping day, get off the bus and a guy was wrenching on his battery, alternator clicking - I went into the store. just about to walk out and he tries it again - boom - acid all over the front of the store
04:39 PM JT-Shop: I just got my massive jumper cables out and jumped from the + on the battery to the solenoid... nothing
04:39 PM JT-Shop: jumped from battery to battery from the tractor next to it and nothing
04:40 PM JT-Shop: the + from the solenoid goes to the batt on the switch, so pretty short about 2'
04:41 PM JT-Shop: gotta cool down a bit and start with the meter again...
04:41 PM JT-Shop: the dumb charger is putting out 6 amps
04:41 PM Tom_L: it's hiding in there somewhere
04:41 PM JT-Shop: yup
04:43 PM rdtsc: bad switch, or bad battery negative?
04:44 PM Tom_L: i think he changed the switch too
04:45 PM JT-Shop: new switch
04:46 PM Tom_L: if you went straight to the solenoid from the battery in my mind it must be in the return GND path
04:47 PM JT-Shop: hmm, I could put the jumper cable on the - and + and see
04:48 PM Tom_L: it might shorten the dianostic time
04:53 PM JT-Shop: https://fairwindfasteners.com/blogs/news/reed-prince-frearson-drive-vs-phillips
04:56 PM Tom_L: let's have yet another screw head drive pattern
04:56 PM Tom_L: that one's not necessarily new though
04:56 PM JT-Shop: it's a very old screw drive
04:57 PM Tom_L: i think that playhouse had 3-4 different types
04:57 PM Tom_L: mostly square drive
04:58 PM JT-Shop: it's a pia when something has different screw types
05:03 PM roycroft: that brings us to at least 4 cross-shaped screw head types
05:06 PM Tom_L: https://www.buyspares.co.uk/images/consumer_sites/advice_centre/articles/screwtypes.jpg
05:13 PM JT-Shop: success Tom_L was correct
05:14 PM JT-Shop: jumpered both - and + to solenoid and she cranked right over
05:14 PM JT-Shop: so bad negative cable or connection
05:15 PM Tom_L: yay
05:17 PM JT-Shop: the negative cable clamp does look a bit dodgy
05:17 PM Tom_L: i'd say a new cable would be in order
05:17 PM JT-Shop: yup
05:18 PM JT-Shop: and I'm so glad I don't have to wrestle that damn battery out
05:18 PM Tom_L: :D
05:33 PM JT-Shop: looking at the ground cable and the insulation is flaked away and it's green... and it's going to be fun to replace
05:34 PM Tom_L: been going for quite a while then
05:34 PM JT-Shop: yup
05:35 PM JT-Shop: they made them from 82-86 so pretty old
05:36 PM JT-Shop: it could be as old as the C3
05:37 PM JT-Shop: I'll have to crawl under it to disconnect the cable from the transmission housing
05:37 PM Tom_L: it's probably longer than the + cable too
05:38 PM JT-Shop: no, it's about 3' long
05:38 PM JT-Shop: the + is maybe 2' longer
05:38 PM JT-Shop: starter is on the other side from the battery
05:38 PM Tom_L: what's it look like? the + one
05:38 PM Tom_L: oh
05:39 PM JT-Shop: the + looks ok
05:39 PM Tom_L: same effect as the zinc on the boat thing
05:40 PM JT-Shop: the negative has been repaired in the past with a replacement battery clamp
05:40 PM Tom_L: so it's not the first time either
05:41 PM JT-Shop: nope, I replaced all the battery cables in the `56 Ferguson when I rebuilt it
05:55 PM JT-Shop: I just need to put some cardboard under the hoe to make a bed for me lol
05:56 PM Tom_L: i keep a small pile of fair sized ones on hand for those moments
05:56 PM JT-Shop: yup me too
05:58 PM JT-Shop: I keep them between two sets of shelves in the big shop
05:59 PM JT-Shop: just have to watch out for brown recluse spiders
06:00 PM Tom_L: yeah
06:00 PM roycroft: we have no poisonous spiders here
06:00 PM roycroft: and rattlesnakes are all east of the mountains
06:01 PM roycroft: hmm, there may be some rattlesnakes west of the mountains in southern oregon
06:02 PM roycroft: but certainly nowhere near here
06:06 PM JT-Shop: even almost stale rice crisps are good
06:08 PM JT-Shop: we have poisonous snakes but I've only see a couple around here in all the years I've lived here
06:09 PM Tom_L: same here
06:10 PM Tom_L: but aparently the kid brought home a cotton mouth in his truck from work a few weeks back
06:10 PM JT-Shop: iirc I've seen two copper heads and really cool was to see a king snake
06:10 PM JT-Shop: most of them are black snakes or some form of garter snake
06:11 PM JT-Shop: I remember that
06:11 PM Tom_L: water mocasin... same thing i think
06:12 PM JT-Shop: I think of south louisiana for them
06:15 PM Tom_L: he parks in a different spot now :)
06:16 PM JT-Shop: time to get a new fridge
06:16 PM Tom_L: good luck
06:16 PM JT-Shop: or fix this one lol
06:17 PM JT-Shop: but I need to deliver the surface grinder first
06:17 PM JT-Shop: gotta get it out of here
06:17 PM lcnc-relay: <pink_vampire@> xxcoder@: Hopefully I will have my g0704 working soon
06:17 PM xxcoder: cool :)
06:23 PM lcnc-relay: <pink_vampire@> So making new side plate or modified the original will be a breeze, but the side of the "maker slides" looks like a regular XX 80/20 extrusion, so hopefully I can just reuse the holes of the maker slides and fit regular extrusions that are much longer. But I don't know for sure until I will take it apart and share some pictures with you all(I think maker slides is the name of the aluminum extrusions that they inventable CNC...
06:23 PM lcnc-relay: ... machine use)
06:23 PM xxcoder: cool. hope youre successful :D
06:24 PM * JT-Shop calls it a day
07:12 PM lcnc-relay: <.le_potato@> what can i do with backlash and accell?
07:12 PM lcnc-relay: <.le_potato@> if i give too much accell it skipping steps
07:13 PM lcnc-relay: <.le_potato@> if not enough accell then bouncy
07:14 PM Tom_L: find a happy medium
07:16 PM Tom_L: read the INI section in the Integrator's manual about using backlash
07:17 PM Tom_L: i'd try to fix it mechanically or deal with it
07:19 PM lcnc-relay: <.le_potato@> i see
07:19 PM lcnc-relay: <.le_potato@> i was totally idiot
07:19 PM Tom_L: http://linuxcnc.org/docs/stable/pdf/LinuxCNC_Integrator.pdf
07:19 PM lcnc-relay: <.le_potato@> max_accel != max_acceleration
07:19 PM Tom_L: oh
07:20 PM Tom_L: no they're spelled different :)
07:20 PM lcnc-relay: <.le_potato@> yess!
07:23 PM lcnc-relay: <.le_potato@> works perfect :))
07:23 PM Tom_L: devil is in the details
07:31 PM lcnc-relay: <.le_potato@> Tom_L: http://gumicsonak.ddns.net/nc/index.php/s/B6MCJcKmrWcYZFb
07:31 PM lcnc-relay: <.le_potato@> looks goodish, this was with bad Y
07:32 PM Tom_L: much better than the other one
07:33 PM lcnc-relay: <.le_potato@> i have to lift the spindle motor to fit cylinder head
07:34 PM Tom_L: make some strap clamps to use with your bolts
07:34 PM lcnc-relay: <.le_potato@> https://merfol.unas.hu/spd/305039/Gombmaro-HF-D-127x110x60x56-mm-Z6
07:34 PM lcnc-relay: <.le_potato@> and buy this one
07:35 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/Mill_Steel/Assembly/Final/Strap_clamp.jpg
07:35 PM lcnc-relay: <.le_potato@> http://gumicsonak.ddns.net/nc/index.php/s/67RKeybZzw8mk7H
07:35 PM Tom_L: i made my own
07:35 PM lcnc-relay: <.le_potato@> this is how its mounted
07:36 PM lcnc-relay: <.le_potato@> i have to make a higher mount
07:37 PM Tom_L: do you modify the cylinder combustion chamber?
07:37 PM Tom_L: what do you mill on them
07:37 PM lcnc-relay: <.le_potato@> porting the cylinder head intake
07:37 PM Tom_L: ok
07:37 PM lcnc-relay: <.le_potato@> basicly its a simple stuff
07:38 PM lcnc-relay: <.le_potato@> with 3d scanner and fusion360
07:38 PM Tom_L: i thought that was usually done by hand
07:38 PM Tom_L: fancy
07:38 PM lcnc-relay: <.le_potato@> yes because peoples have no machine for it
07:38 PM lcnc-relay: <.le_potato@> or they dont know how to do it
07:38 PM lcnc-relay: <.le_potato@> or too expensive with machine
07:38 PM lcnc-relay: <.le_potato@> they ask 3-5k$
07:39 PM Tom_L: what sort of engines?
07:39 PM Tom_L: for competetion obviously
07:40 PM lcnc-relay: <.le_potato@> yes
07:40 PM lcnc-relay: <.le_potato@> bmw engines
07:40 PM lcnc-relay: <.le_potato@> they made on 3 axis machine in the factory
07:40 PM lcnc-relay: <.le_potato@> so easy to port
07:42 PM Tom_L: so when your competetion comes looking for lcnc help, i should help them more?
07:42 PM lcnc-relay: <.le_potato@> haha
07:42 PM lcnc-relay: <.le_potato@> sure!
07:42 PM Tom_L: :)
07:42 PM lcnc-relay: <.le_potato@> there is enough work for everybody!
07:43 PM Tom_L: i forget, do bmw use the wafers for valve adjustment?
07:43 PM Tom_L: it's been years since i've seen the inside of one
07:43 PM roycroft: my fiat had those
07:43 PM Tom_L: jag does i know
07:43 PM lcnc-relay: <.le_potato@> its hydraulic lifter
07:43 PM Tom_L: my fiat did also
07:44 PM Tom_L: you don't switch to hard lifters?
07:44 PM roycroft: it pretty much means you can't adjust the valves yourself, unless you have a big kit of various size wafers
07:44 PM Tom_L: i still have a handfull of cups in my tool box but who knows what engine...
07:44 PM Tom_L: right
07:44 PM lcnc-relay: <.le_potato@> i think its expensive because people buy new CNC and cant build their own
07:45 PM Tom_L: or measure real good and buy the ones you need
07:45 PM roycroft: europeans do not generally do their own vehicle maintenance like we do here in the states
07:45 PM Tom_L: i know
07:45 PM roycroft: and it's been that way forever
07:46 PM Tom_L: they're almost like doctors are here
07:46 PM roycroft: so european cars are usually not as easy for a backyard mechanic to maintain
07:46 PM Tom_L: mechanics
07:46 PM lcnc-relay: <.le_potato@> thats true
07:46 PM lcnc-relay: <.le_potato@> complicated shits
07:46 PM roycroft: the guys in the fiat shop in bellingham used to wear lab coats
07:46 PM Tom_L: merc has a special tool for everything
07:46 PM roycroft: they really were like doctors
07:47 PM Tom_L: i know
07:47 PM lcnc-relay: <.le_potato@> so when i milling cylinder head, thats why i dont need home points or toucher
07:47 PM lcnc-relay: <.le_potato@> because i have to set it manual
07:47 PM lcnc-relay: <.le_potato@> if i breaks something, i will be 5cm deep in cylinder head
07:47 PM lcnc-relay: <.le_potato@> i got some for testing
07:47 PM Tom_L: you still have to home the machine though
07:47 PM Tom_L: then zero the offset where you want it
07:48 PM Tom_L: every port is gonna be a bit different
07:48 PM lcnc-relay: <.le_potato@> yeah for that i ordered
07:48 PM lcnc-relay: <.le_potato@> for every port i have to move the cylinder head
07:48 PM Tom_L: since the intake/exhaust are as well
07:48 PM lcnc-relay: <.le_potato@> http://gumicsonak.ddns.net/nc/index.php/s/m9yTxDisGekZqAp
07:49 PM Tom_L: do you port the intake manifold too?
07:49 PM Tom_L: or just try to match them
07:49 PM Tom_L: lots of blue dykem
07:50 PM Tom_L: years ago i worked at a place that had a flow bench
07:53 PM lcnc-relay: <.le_potato@> flow bench worth nothing on cylinder heads
07:54 PM Tom_L: it was mostly set up for VW
07:56 PM lcnc-relay: <.le_potato@> http://gumicsonak.ddns.net/nc/index.php/s/FpWHDMJeC4ZYcpG
07:56 PM lcnc-relay: <.le_potato@> this is how it fits
07:58 PM lcnc-relay: <.le_potato@> i have to go down 60mm
08:00 PM lcnc-relay: <.le_potato@> i can adjust my Z little lower with the bump stop
08:00 PM lcnc-relay: <.le_potato@> maybe thats enough
08:02 PM Tom_L: you should make a jig to hold them
08:02 PM Tom_L: i assume you pull the studs before milling
08:03 PM Tom_L: not alot of spare room there
08:04 PM Tom_L: we machined a blower hat for a racecar once. some of the cutters were 8" long
08:04 PM Tom_L: that was also a tight fit
08:08 PM lcnc-relay: <.le_potato@> i found out why there was a DIY bump stop
08:08 PM lcnc-relay: <.le_potato@> because now its connected again with machine's mechanical Z axis, lol
08:08 PM lcnc-relay: <.le_potato@> not the servo one
08:08 PM lcnc-relay: <.le_potato@> *stepper
08:10 PM lcnc-relay: <.le_potato@> i have to call my cnc repair guy
08:11 PM lcnc-relay: <.le_potato@> i broke the machine by reconnecting Z axis somehow, lol
08:21 PM Tom_L: woops
08:34 PM lcnc-relay: <.le_potato@> im not even have to scan cylinder head because somebody did it and asking for 15$ for it
08:38 PM Tom_L: do you have a way to turn the point cloud into a model?
08:50 PM lcnc-relay: <.le_potato@> what you mean?
08:50 PM lcnc-relay: <.le_potato@> in to STL yes
08:55 PM lcnc-relay: <.le_potato@> im afraid about its not a proper scan
09:06 PM lcnc-relay: <skunkworks8841@> Been running the rpi5 on the plasma the last few days - no issues what so ever
09:39 PM lcnc-relay: <.le_potato@> i would not trust in a mobile phone
10:01 PM roycroft: mobile phones are ok
10:01 PM roycroft: it's mobile phone users i don't trust
10:05 PM Tom_L: skunkworks, that's good news
10:06 PM Tom_L: 1ms servo thread?
10:07 PM lcnc-relay: <.le_potato@> why 1ms thread is important?
10:07 PM lcnc-relay: <.le_potato@> i using 2ms
10:26 PM lcnc-relay: <skunkworks8841@> Yes . 1ms
