01:20 AM jepler1088[m]: Was getting e-mails that the forum machine's storage was nearly fully, tidied some things, but eventually we'll have so many attachments we have to go to a higher disk size on digitalocean.
01:29 AM XXCoder: heyy jepler1088[m]
01:29 AM jepler1088[m]: hi
01:29 AM XXCoder: been looking for you to add permit for one bot to bridhe discord, matrix and liberia irc
01:29 AM XXCoder: ask TurBoss
01:29 AM XXCoder: (for dev channel)
01:29 AM jepler1088[m]: OK, d'you konw if the people in the -dev channel are largely on board with it? I'm out of touch times one thousand
01:29 AM XXCoder: dont know either, turboss is one thats there
01:29 AM jepler1088[m]: I don't want to foist something that's unwelcome, or prevent something that's welcome. I just don't know.
01:29 AM CaptHindsight[m]: everybody is fine with it, they just don't know who has admin rights
01:30 AM CaptHindsight[m]: jepler#1088: only takes a minutes IF Turboss is around
01:31 AM CaptHindsight[m]: one minute
01:31 AM CaptHindsight[m]: and he's not so, :(
01:31 AM jepler1088[m]: OK, well, I'm heading out in a minute
01:31 AM XXCoder: jep thanks and later
01:32 AM XXCoder: in least you know now :D
01:32 AM CaptHindsight[m]: maybe next Blue Moon
01:34 AM roycroft: https://extensions.joomla.org/extension/s3-media/
01:34 AM roycroft: it looks fairly straightforward
01:34 AM roycroft: i'd at least do a cost comparison
01:35 AM roycroft: there's a learning curve to s3 though
01:35 AM CaptHindsight[m]: we need a LCNC bake sale to raise funds for more space
01:39 AM CaptHindsight[m]: https://matrix.to/#/#lcnc-devel:jauriarts.org Turboss did make another matrix server already
01:40 AM CaptHindsight[m]: just not bridged yet
01:40 AM roycroft: i suggestd a patreon-like thing a few months ago
01:40 AM roycroft: where folks could make small, regular contributions to help out
01:40 AM roycroft: there didn't seem to be much interest
01:41 AM CaptHindsight[m]: well did you mention cookies or cake?
01:41 AM roycroft: i'd be happy to donate a dollar or two per month, or $20/year, or something like that to help out
01:41 AM roycroft: no
01:41 AM roycroft: just the giving money part
01:41 AM roycroft: not the getting diabetes part
01:42 AM CaptHindsight[m]: the next hurdle is who gets the cash and who makes the payment to the host service
01:44 AM CaptHindsight[m]: requires some keys, like the git
01:44 AM roycroft: all that can be managed
01:45 AM roycroft: instead of a bake sale, you could set up a merch store
01:45 AM roycroft: and sell linuxcnc coffee mugs, tee-shirts, and hats
01:45 AM roycroft: with all profits going to pay for hosting the forum
01:46 AM CaptHindsight[m]: sure, check with management
01:47 AM randy: morning
01:48 AM CaptHindsight[m]: LCNC milling and turning marathon, live streamed
02:20 AM xxcoder8265[m]: https://imgur.com/jMkZyDr.png
02:20 AM xxcoder8265[m]: slowly getting there. still missing front cover
02:27 AM randy: looks like a part of a spaceship. or sattelite. :)
02:34 AM xxcoder8265[m]: lol
02:34 AM xxcoder8265[m]: its rotating table machine
02:35 AM xxcoder8265[m]: it may not be too complex, but its designing everything myself
02:36 AM xxcoder8265[m]: https://imgur.com/DbdPMWB.png
02:36 AM xxcoder8265[m]: without top
02:37 AM randy: so stepper direct without planetary gear drive to the table?
02:37 AM randy: and how do you plan to index?
02:37 AM randy: (just curious, no offense :))
02:37 AM xxcoder8265[m]: it wont have any indexing of any kind
02:37 AM randy: ic
02:37 AM xxcoder8265[m]: it'll just rotate. gear ratio cannot be "faster" with planetary gear ssystem
02:38 AM randy: not faster, but higher torque. since the table has a large radius, i assume there are high forces when cutting stock material near to the border of the table
02:39 AM xxcoder8265[m]: cutting?
02:39 AM randy: i thought its for cnc sorry
02:39 AM randy: :)
02:39 AM xxcoder8265[m]: oh sorry wasnt clear. my fault lol its just to rotate away while take pictures or whatever πŸ˜„
02:40 AM randy: np, i only had a half cup of coffee yet, it's early :)
02:40 AM xxcoder8265[m]: https://tenor.com/view/breakfast-of-champions-gif-21066898
02:41 AM randy: hehe
02:41 AM randy: reminds me of "my doctor advised me to trink only one glass of redwine per day"
02:45 AM xxcoder8265[m]: πŸ˜„
03:42 AM travis_farmer853: G'Morning β˜•
03:42 AM travis_farmer853: i read up the back log... if LinuxCNC gets a Merch store, i would be onboard with helping by buying merch. πŸ™‚ well, once i start making money again... πŸ€”
05:06 AM JT-Cave: morning
05:16 AM Tom_L: morning
09:44 AM roguish[m]: house painters here today, for a few days. gonna look good when they're done.
10:58 AM roycroft: happy friday!
10:59 AM roycroft: and it's a long weekend here in the usa
11:00 AM travis_farmer853: WooHoo!!! course... i am now out of work, so all days are a weekend... unfortunately
11:01 AM roycroft: my goal is to have some of my drawers assembled and installed by the end of the holiday weekend, and i think i can get that done
11:02 AM roycroft: if it were a regular weekend, not so much
11:08 AM JT-Cave: I started my weekend yesterday
11:10 AM travis_farmer853: i started my weekend too long ago. really missing the paychecks 😦
12:31 PM roguish[m]: hey. are the mailing lists down?
12:41 PM sinned6915: can I get some advice on a suitable pc?
12:41 PM sinned6915: choice is optiplex 755 wth core2duo or dimension with a P4
12:41 PM sinned6915: is one 'better' than the other?
12:42 PM travis_farmer853: are you using a mesa card, or a parallel port to drive your machine?
12:42 PM sinned6915: i did not see much mention of either on the latency thread
12:42 PM sinned6915: hoping for parallel port
12:45 PM Rab: I think the right answer is to run the latency test on both, but all else being equal I'd go for the core2duo.
12:45 PM travis_farmer853: if parallel port, you need good real-time performance, but that is not necessarily the same as computing performance. mostly a trial and error to fine the right match
12:47 PM sinned6915: yeah, im trying to hedge a bet on time spent
12:49 PM roguish[m]: sinned6915: seriously depends on your expectations. are you building or retofitting a huge cnc, or building a small shop router...? what precision and speeds do you need.............
12:49 PM sinned6915: retrogitting a small knee mill
12:50 PM sinned6915: small shop. manual collets
12:51 PM roguish[m]: so, modest requirements.
12:51 PM roguish[m]: good start
12:53 PM sinned6915: k, thanks all.
12:53 PM sinned6915: i'm sure iwill be back with questions as I wire/config
01:20 PM JT-Shop: you know it's summer time when you almost step on a snake
01:21 PM XXCoder: lol its different for me
01:21 PM XXCoder: I know its almost summer when I feel half dead
01:23 PM travis_farmer853: i know it's summer when the leave are green once again. πŸ™‚
01:23 PM travis_farmer853: s/leave/leaves/
01:49 PM djsftree[m]: Hi! Quick question. My encoder has REAL format. Using halType float doesnt return the correct value. If i grab the data as halType u32 and convert that to flat it seems ok. How can I do this hal?
01:50 PM djsftree[m]: 24 u32 OUT 0xC28A5415 lcec.0.encX.encoder.a1.raw... (full message at https://libera.ems.host/_matrix/media/r0/download/libera.chat/6118d7899bbf56cf52ddd1d1eea7905887e2ab23)
01:50 PM djsftree[m]: * 24 u32 OUT 0xC28A5415 lcec.0.encX.encoder.a1.raw... (full message at https://libera.ems.host/_matrix/media/r0/download/libera.chat/6e67801d852a0ddb567284247664b1e7e6a4dcea)
01:53 PM djsftree[m]: If is use a an online converter the hex to flat looks right https://gregstoll.com/~gregstoll/floattohex/ ies, stuff in the 0xC2B range is about -90 degrees, 0x42B about +90.
01:53 PM djsftree[m]: s/flat/float/
01:54 PM djsftree[m]: * Hi! Quick question. My encoder has REAL format. Using halType float doesnt return the correct value. If i grab the data as halType u32 and convert that to float it seems ok. How can I do this converions from hex to float in servo-thread / hal?

01:55 PM XXCoder: I'd suggest use dpaste for longer messages. and avoid editing
01:55 PM XXCoder: because we get full message each time you edit ;)
01:57 PM djsftree[m]: oh!?! that's crazy.
01:57 PM djsftree[m]: I'm new to discord... sorry.
01:58 PM XXCoder: its just irc works, since theres no edit for irc. (this channel is bridged to matrix and irc as title says)
01:58 PM djsftree[m]: I didn't realised edits essential "reposted" the message
01:59 PM djsftree[m]: "bridged to matrix and irc as title says" - sorry didn't realise the implications of that bridge.
02:04 PM xxcoder8265[m]: no problem lol
02:07 PM travis_farmer853: i wondered what happened when i forgot and edited... i do apologize for my past edits, and likely my future ones too, when i forget. πŸ™‚
02:08 PM xxcoder8265[m]: its fine. btw quoted part dont show in irc, so might add a word or two if its been a while between text thats being quoted and your comment
02:09 PM travis_farmer853: ... ok, didn't realize. very good to know
02:09 PM XXCoder: bridging is new for linuxcnc so its still bit of adjustment lol
02:10 PM XXCoder: 2 channels is bridged on discord, development not yet
02:10 PM travis_farmer853: yeah, especially when people have split personalities (both discord and irc) πŸ˜‰
02:10 PM XXCoder: yeah. im admin there and op here lol
02:36 PM djsftree[m]: I gave up writing the C linuxcnc-ethercat driver and reverted to manual pdo / xml file. Not as straight forward as I hoped. More learning to do.
02:38 PM XXCoder: learning is always needed :D
02:46 PM djsftree[m]: so why would "halType=float" not yield the same figure as "halType=u32" > raw hex > read as float? Hmm.
02:48 PM djsftree[m]: I think I may need a halcompile comp to take raw hex from the raw u32 bits and read as float that way
03:04 PM -!- #linuxcnc mode set to +v by ChanServ
03:07 PM roycroft: my plan is to not stop learning until the day i die
03:07 PM roycroft: and who knows? maybe there really is an afterlife, in which case i'll have learned something even after i die
03:09 PM roycroft: what i'm learning right now is that if i don't hurry up and finish the cabinet project i'm not going to get my cnc router built by the end of the summer
05:15 PM roycroft: and the holiday weekend begins in just over a minute
05:15 PM roycroft: and i only have one meeting this weekend - this evening
05:41 PM xxcoder8265[m]: https://youtu.be/J8qtSIwa7yo
05:42 PM xxcoder8265[m]: pretty cool. one peice though hmm
06:51 PM bjorkintosh: is the post for spitting out g-code for various machines standardized anywhere?
06:53 PM XXCoder: not really. cam varies since machines do
06:54 PM XXCoder: there tend to be groups though
06:54 PM XXCoder: like FAUNC type
06:55 PM bjorkintosh: but even in the fanuc manuals, I don't see much of anything related to post
07:02 PM XXCoder: well hope someone can answer more effectively :D
07:07 PM Tom_L: bjorkintosh, you probably wouldn't find that in a fanuc manual
07:07 PM Tom_L: rather in a cad cam manual
08:48 PM bjorkintosh: Tom_L, is there a good one to look at?
08:49 PM Tom_L: every one of them is going to be different. i would say it would depend on which cad cam you plan to use
08:49 PM Tom_L: i have one i used years ago and now i just use it for hobby but i have taylored it to work with linuxcnc nearly flawlessly
08:50 PM Tom_L: are you wanting one for linuxcnc or for fanuc?
08:51 PM Tom_L: iirc we had one for fanuc 10m
08:52 PM bjorkintosh: fanuc
08:53 PM Tom_L: find a gcode list for it first so you know what needs to be supported
08:53 PM Tom_L: http://www.helmancnc.com/fanuc-g-code-list/
08:56 PM Tom_L: https://www.cnccookbook.com/g-code-m-code-command-list-cnc-mills/
09:05 PM Tom_L: if you're using fusion360 they have a fanuc post: https://cam.autodesk.com/hsmposts
09:06 PM Tom_L: the one i have for my old cad cam looks very basic
09:38 PM bjorkintosh: so each cam system has its own post syntax, is that it?
09:38 PM XXCoder: not quite
09:38 PM XXCoder: many cam programs can select output type
09:49 PM bjorkintosh: so the syntax is not vendor specific?
09:49 PM XXCoder: it can be, it really depends
09:49 PM bjorkintosh: it doesn't help that they don't bother publishing manuals these days.
09:49 PM bjorkintosh: it's all "online" somewhere.
09:49 PM XXCoder: if machine is stated to be FAUNC for example, it should support gcode export for faunc
09:49 PM bjorkintosh: ie, the software companies.
09:50 PM XXCoder: though its interesting how sometimes it works after minor rewrite.
09:50 PM bjorkintosh: yes. I know that much. what I'm getting at is that the post processor has *syntax* that I want to study.
09:50 PM bjorkintosh: to get better output.
09:50 PM bjorkintosh: but it's clear that it's not universal. or not quite universal.
09:50 PM XXCoder: for example I could convert any HAAS machine gcode to old fadal by simply swapping t1 m6 to e1 m6 for example, and couple other minor changes
09:50 PM bjorkintosh: yes. but that's just g-code.
09:51 PM ZincBoy[CAON]066: The thing is that there is not even a fixed post for Fanuc as pretty much every machine will require changes to the post to customize for installed features and machine capabilities. Different CAM programs will have completely different post syntax.
09:51 PM bjorkintosh: this is an example: https://www.scribd.com/doc/188927800/Introduction-to-the-ESPRIT-post-processor
09:51 PM ZincBoy[CAON]066: Gcode is not standardized in any real way.
09:51 PM bjorkintosh: but it is.
09:51 PM XXCoder: zinc yeah. id say "more or less" for modern
09:51 PM bjorkintosh: there are two prevailing standards.
09:51 PM XXCoder: older, not so much
09:52 PM XXCoder: recall my earlier statement of using E for tool numbers. now that was ...unique
09:52 PM bjorkintosh: RS 274 and the ISO version.
09:52 PM XXCoder: old okuma mill, man how I hated that one. it will error out if you change from tool to same tool
09:52 PM XXCoder: that includes if you START program with same tool as first tool
09:53 PM ZincBoy[CAON]066: The basic syntax (ISO and RS274) is now standardized but that only counts for the really simple functions.
09:53 PM ZincBoy[CAON]066: You still need to customize the post for the specific machine.
09:53 PM XXCoder: its far more nasty when program uses only ONE tool.
09:53 PM bjorkintosh: ISO 6983. and RS-274
09:53 PM ZincBoy[CAON]066: This may be more or less complex between models depending on the manufacturer.
09:54 PM bjorkintosh: ZincBoy[CAON]066> You still need to customize the post for the specific machine. yes.
09:54 PM bjorkintosh: I thought there was a common source for that.
09:54 PM bjorkintosh: turns out as I've recently found out, that it's ... up in the air.
09:54 PM ZincBoy[CAON]066: Absolutely not.
09:55 PM ZincBoy[CAON]066: It depends on the machine, control, and CAM software used.
09:56 PM bjorkintosh: geeze. the ISO manuals are really expensive.
09:57 PM bjorkintosh: priced for corporate budgets.
09:58 PM ZincBoy[CAON]066: They are available with a bit of searching πŸ™‚ But yes any of the ISO standards are not cheap.
09:58 PM bjorkintosh: my google-fu is full of SEO crap
10:17 PM Tom_L: fanuc is a control used on different types of machines which may or may not implement all the gcodes available
10:19 PM bjorkintosh: I believe they all can. it's afterall a question of memory isn't it? it's just that some functions are turned off.
10:24 PM Tom_L: a lathe could use a fanuc control as could a mill but the codes would be different
10:25 PM Tom_L: so then the post becomes more specific
10:25 PM Tom_L: what is it you're trying to do?
11:01 PM bjorkintosh: <Tom_L> what is it you're trying to do? trying to learn more about posts to modify them accordingly.
11:01 PM bjorkintosh: there's no damned book on the subject, unfortunately.
11:02 PM bjorkintosh: I figured this would be a good place to ask.
11:12 PM bjorkintosh: trial and error is the only other viable alternative.
11:19 PM Tom_L: you should probably settle on a cad cam package then concentrate on their post format
11:19 PM Tom_L: mine is quite old and i don't think you will find many like it nowdays
11:19 PM ZincBoy[CAON]066: There are books on modifying posts. They are specific to the CAM software and usually come with the software. Each machine will have a manual for the control, how it is configured, and how the gcode needs to be implemented. Put these together and you get a correct machine specific post with no trial and error required. There is no standard for this. ISO and RS-274 define the syntax of gcode but do not define how it is used.
11:22 PM Tom_L: https://www.smartcamcnc.com/LearnSmartCAM/current/Default.htm#chap7_codegen/codegen_overview.htm?TocPath=Code%2520Generation%257C_____0
11:23 PM Tom_L: that would be similar to mine now but you will find each cam package does it a little different
11:24 PM Tom_L: catia uses a 3rd party cam and must be purchased per machine extra i believe
11:25 PM Tom_L: not sure what solidworks approach is
11:25 PM Tom_L: mastercam is another popular one
11:25 PM Doc4133[m]: Why would a 7i96 just not power on?
11:25 PM ZincBoy[CAON]066: Soildworks has their own CAM as well as a whole pile of plug-ins. I use BobCAD for my CAM.
11:26 PM Tom_L: i'm sorry
11:26 PM Tom_L: ;)
11:26 PM Tom_L: i looked at it years ago... is it any better now?
11:27 PM Tom_L: Doc4133[m], does it require a field voltage to be enabled first? i'm not sure
11:27 PM Tom_L: some boards do
11:27 PM ZincBoy[CAON]066: Lol. It is much better and it is still the best price/performance for my needs.
11:27 PM drdoc: Tom_L: I was running it yesterday without issue
11:27 PM Tom_L: i bought mine years back when i did it commercially
11:28 PM XXCoder: i havent really needed a cam
11:28 PM Tom_L: drdoc, check the voltages
11:28 PM drdoc: 12V on the isolated I/O pins, 5VDC 1A on the 5V connector
11:28 PM XXCoder: I last used etslcam for cam, it was ok
11:28 PM drdoc: have done
11:28 PM XXCoder: its more expensive and new owner since then
11:28 PM Tom_L: dunno
11:28 PM XXCoder: freecad has a cam, but never tried that
11:29 PM drdoc: I'm running it off an Advantech 12V/5V power supply
11:29 PM Tom_L: it's probably iffy since it's fairly new
11:29 PM drdoc: Not Junk
11:29 PM * ZincBoy[CAON]066 uploaded an image: (1165KiB) < https://libera.ems.host/_matrix/media/r0/download/jauriarts.org/xmgqrcbclHfWNVnLMyFJsYcA/IMG_0916.jpg >
11:29 PM ZincBoy[CAON]066: I don't want to do this type of thing without CAM:
11:29 PM drdoc: and I've tried a couple of other supplies since it failed
11:30 PM drdoc: There's not 50 hours on this board
11:30 PM XXCoder: zinc nice work
11:30 PM Tom_L: ZincBoy[CAON]066, that's all 2.5d
11:30 PM Tom_L: but yeah it would take a while
11:32 PM Tom_L: what's it for?
11:32 PM ZincBoy[CAON]066: Yes, but I used 3d tool paths for chamfering πŸ™‚ It took about 2 hours to program that. 3 setups and 16 tools. I don't want to think about how long it would take by hand.
11:33 PM ZincBoy[CAON]066: It is for a RF/optical board. Includes water cooling.
11:33 PM Tom_L: the backside machined too?
11:33 PM * ZincBoy[CAON]066 uploaded an image: (1165KiB) < https://libera.ems.host/_matrix/media/r0/download/jauriarts.org/OJNHtmZGmzexGOvKZbwnNNEI/IMG_0917.jpg >
11:34 PM Tom_L: the chamfers came out nice
11:35 PM Tom_L: did you rigid tap the holes?
11:36 PM ZincBoy[CAON]066: Yes, M3 and M2. Form tapping for both.
11:37 PM Tom_L: threadmill or tap?
11:38 PM Tom_L: i wrote a macro for my old cad to do single point
11:38 PM Tom_L: it didn't have anything for that
11:39 PM Tom_L: i've not tried a full form thread mill but it would work the same
11:39 PM bjorkintosh: vb macro?
11:39 PM Tom_L: no
11:39 PM Tom_L: my cad is probably 30 yrs old :)
11:39 PM bjorkintosh: we use autocad 2000 at work.
11:39 PM * ZincBoy[CAON]066 uploaded an image: (1225KiB) < https://libera.ems.host/_matrix/media/r0/download/jauriarts.org/tGrGfRQRJDzGhTOyVHiCvUjB/surfacedetail.jpg >
11:39 PM ZincBoy[CAON]066: Tap. Here is one that uses 3d, rigid tapping and single point threading:
11:39 PM bjorkintosh: it's actually superb.
11:40 PM Tom_L: i set rigid tapping up on a sherline when i had it
11:40 PM Tom_L: the spindle motor wasn't strong enough to do much
11:41 PM ZincBoy[CAON]066: For what may I ask? I really was happy to get away from autocad to a parametric system.
11:41 PM Tom_L: yeah i think acad sucks for machine work
11:43 PM ZincBoy[CAON]066: Yes, I ran into that on my old mill. The new machine will run a 3/4" tap into steel all day without blinking. It will also shatter that tap when you program the wrong feed in the tap cycle πŸ™‚
11:43 PM bjorkintosh: ZincBoy[CAON]066, primarily creating profiles for the feature cam software. it's a whole lot easier.
11:43 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/extinguisher_nut/Pressure_test_cap3.jpg
11:43 PM Tom_L: those were single point
11:44 PM bjorkintosh: ZincBoy[CAON]066, what do you use? featurecam? solidworks?
11:44 PM ZincBoy[CAON]066: Nice. I have a few different sizes of threadmill to do oddball threads.
11:44 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Thread_mill3.jpg
11:45 PM Tom_L: check onlinecarbide... they're fairly reasonable
11:46 PM ZincBoy[CAON]066: Very nice. That looks like a good range. I will check out onlinecarbide.
11:46 PM Tom_L: it covers most threads i'd ever cut
11:47 PM Tom_L: they have form threads too
11:47 PM Thorhian7490[m]: Lol, redtool/onlinecarbide is good stuff on eBay from what I have seen.
11:47 PM Tom_L: i've been using their cutters
11:47 PM ZincBoy[CAON]066: I use Alibre for design, BobCAD for CAM, Fusion360 for FEA and mesh work.
11:48 PM Tom_L: that or lakeshore
11:48 PM Tom_L: lakeshore cost more
11:49 PM Tom_L: a little higher quality
11:49 PM Tom_L: not that much though
11:49 PM Thorhian7490[m]: I really want to buy one of these: http://onlinecarbide.com/13fl37hezrn2.html
11:49 PM Tom_L: i use catia or solidworks then import to my cad cam
11:50 PM Tom_L: Thorhian7490[m], i use those
11:50 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/cutters/Carbide_comparison1.jpg
11:50 PM Tom_L: lakeshore has a little higher helix but hardly noticeable
11:51 PM Thorhian7490[m]: Got a half inch one? I think I’ll initially go with onlinecarbide and then test out some of Helical’s aluminum endmills.
11:52 PM Tom_L: no i stop at .375"
11:52 PM ZincBoy[CAON]066: I use these: https://www.maritool.com/Cutting-Tools-End-Mills-Roughers-3-Flute-Carbide-45-deg-Helix/c78_79_93_198/p17056/1/2-dia-3-Flute-High-Helix-Carbide-Rougher-X-1.0-LOC-ZrN-Coated/product_info.html
11:52 PM Tom_L: but can cut .2 deep full width @ 20ipm
11:53 PM ZincBoy[CAON]066: The big advantage is reducing the volume of swarf.
11:53 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/cutters/Carbide_rougher2.jpg
11:53 PM ZincBoy[CAON]066: Went from having to clear the chip tray every half hour to every half day.
11:53 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/cutters/Carbide_rougher4.jpg
11:54 PM Tom_L: that just looks mean
11:54 PM Thorhian7490[m]: I can only get just above 4900RPM, but I have 1.8 KW 9f power lol. I need larger diameter tooling when I can get away with it.
11:54 PM Tom_L: they also make chip breakers
11:54 PM Tom_L: regular endmills with a chip breaker halfway up
11:54 PM Thorhian7490[m]: Helical makes some mean looking roughing endmills too.
11:56 PM Tom_L: https://www.lakeshorecarbide.com/3flute.aspx
11:56 PM Thorhian7490[m]: They also have multiple helix angles for their aluminum line. Quite nice. One of them even comes with wiper geometry for good floor finishes.
11:56 PM Tom_L: variable flute yes
11:57 PM Tom_L: cuts down on chatter
11:57 PM Thorhian7490[m]: Also, I had no idea maritool made endmills.
11:57 PM Thorhian7490[m]: Oh, yeah, not what I meant though.
11:57 PM ZincBoy[CAON]066: Yes, I use the Maritool variable flute quite a bit in steel.
11:58 PM Thorhian7490[m]: Once I make enough money I plan on replacing my chinesium BT30 holders with maritool holders lol.
11:58 PM Thorhian7490[m]: Or with Tegara ones.
11:59 PM bjorkintosh: chinesium.
11:59 PM ZincBoy[CAON]066: The Maritool holders are very nice. I have a few of them.
