[01:37:19] <miss0r> Ahh. That feeling when you are laying under your land rover, trying to figure out why the pipe to hose joint on the frame for the rear axle is leaking & end up stripping the threads out of the nut while brake fluid runs down your arms.. :)

[02:11:52] <miss0r> CaptHindsight: That would be foolish :) Lanr-rovers are much more fuel efficient than land cruisers.. :) As their primari propulsion IS a land cruiser :D
[02:12:10] <miss0r> still, I love the old thing :D

[05:25:01] <XXCoder> Getty: nice
[05:25:07] <XXCoder> whats you decided on?
[05:28:17] <sensille> i received my first aluminum sheets. is it normal that they're all bent or should i find a different seller?
[05:28:31] <sensille> even a 100x100x10mm block is bent
[05:32:11] <gloops> sensille how bent?
[05:32:44] <gloops> i got some 16mm plates at least a 1mm bow in them, its pretty standard unless you get cast
[05:33:38] <sensille> yeah, a 1 or 2mm but on 100x100 it's a lot
[05:33:44] <gloops> it is
[05:34:02] <sensille> i have the impression it comes from cutting
[05:34:14] <gloops> its when theyre made, they sag
[05:34:33] <gloops> the mic plates are cast then machined flat, much better
[05:34:54] <sensille> so i have to mill them flat first?
[05:35:02] <gloops> but a bit more expensive
[05:35:13] <sensille> but that would cost me several mm
[05:35:16] <gloops> if they need to be flat yeah
[05:35:26] <sensille> so try to straighten them first, then mill
[05:36:09] <gloops> for my z plates i simply mounted the pair of plates with the bow facing the same way, ended up spot on, probably luck
[05:37:03] <gloops> if its a working surface or precision part they need flattening though
[05:37:59] <sensille> where does "precision" start?
[05:38:25] <gloops> in my garage - with 4lb hammer lol
[05:38:40] <sensille> :)
[05:38:54] <sensille> is <1mm already "precision"?
[05:38:58] <gloops> what are the plates for?
[05:39:24] <sensille> functional parts for a 3d printer
[05:39:25] <gloops> 1mm may as well be 1 mile in some situations
[05:39:54] <sensille> and one as a base plate for experimental setup. that needs to be flat
[05:40:19] <gloops> i dont know how the bow would affect the operation of your machine, not knowing the design etc
[05:40:31] <gloops> yes the base needs to be flat
[05:40:56] <gloops> gantry plates things like that, you can maybe adjust the error away
[05:45:36] <gloops> https://www.ebay.co.uk
[05:45:43] <gloops> thats the stuff you want
[05:53:04] <XXCoder> sensille: work materials always is bigger than part by fair mirgin
[05:53:07] <XXCoder> like 3 mm
[05:53:10] <XXCoder> all around
[05:53:20] <XXCoder> thats small parts. larger parts has even more
[05:56:05] <gloops> see you could maybe tighten the bow out if the plate is mounted on a frame...but then the frame has to be flat
[06:01:59] <sensille> XXCoder: that's quite a margin. good to know
[06:02:45] <sensille> gloops: i'll get a tooling plate for my experimentatation board
[06:07:22] <gloops> probably save you some messing about
[06:14:00] -!- P1ersson has quit [Ping timeout: 250 seconds]
[06:16:25] <gloops> something else to consider - if youre using aluminium extrusions for the frame, they too will be out, i found it very helpful when drilling to make slots or oversize holes, to allow a bit of adjustment, dont take it for granted that an extrusion frame will just be square and true - it wont
[06:24:04] <jthornton> morning
[06:24:19] <XXCoder> hey
[06:24:50] -!- Akex_ has quit [Ping timeout: 250 seconds]
[06:26:03] -!- Akex_ has joined #linuxcnc
[06:34:13] <XXCoder> jthornton: how goes your vismach research
[06:35:14] <jthornton> I started reading vismach.py and found a few more bits of info and also found a hud example but have not got it to work yet
[06:35:34] Jin|away is now known as Jin^eLD
[06:37:55] <jthornton> https://github.com
[06:37:58] <sensille> gloops: in which way out? if i test them against each other they're flat, at least for the eye, testing in several directions
[06:38:34] <jthornton> https://github.com
[06:41:01] <XXCoder> HUI to control machine outside linuxcnc?
[06:41:49] <XXCoder> so that poy file is "other end" to vismach
[06:42:03] <XXCoder> traverse ois known to me
[06:42:06] <XXCoder> not
[06:42:22] <XXCoder> wow theres capture command in it
[06:42:35] <XXCoder> but theres also apply draw traverse and unapply
[06:42:43] <jthornton> HUD is a Heads Up Display that should show up on the tk window
[06:42:53] <XXCoder> wow nice
[06:43:36] <XXCoder> "volume" why
[06:43:41] <XXCoder> not sure whats use of that
[06:44:09] <XXCoder> one of possible uses actually is checking if machine is self intecting
[06:44:48] <XXCoder> HALtranslate and rotate also has applu and unapply. wonder what those does. maybe its for linuxcnc side
[06:45:14] <XXCoder> wow! can have multi-viewpoints
[06:45:14] <jthornton> yea I don't understand all I don't know yet lol
[06:45:29] <XXCoder> I wonder if we can define a viewpoint at near spindle for "close up"
[06:45:47] <XXCoder> I bet that can be commanded by HUI
[06:45:53] <XXCoder> change to overall, close up, etc
[06:46:44] <XXCoder> is arc example existant in docs? I think there was but not sure
[06:47:40] <XXCoder> Hud(object)
[06:48:10] <XXCoder> we can change lights maybe
[06:48:43] <XXCoder> if we add pin we could add redraw also, to clear the current tooltip drawn stuff maybe>?
[06:49:03] <jthornton> let me know if you figure something out :)
[06:49:26] <XXCoder> so we have this
[06:50:15] <jthornton> I have to solve a chicken code problem this morning the lights did not add 5 more minutes today for some reason
[06:52:34] <XXCoder> out of known group we have few unknowns like Track, coordsbase, invert (matrix for transformation invert)
[06:52:42] <XXCoder> there also class O looks like lighting stuff
[06:53:08] <XXCoder> also for redraw maybe that causes refresh oif tk window, removing drawn lines
[06:55:02] <XXCoder> hal test is interesting
[06:55:12] <XXCoder> wonder if can capture keyboard input
[06:56:51] <gloops> sensille well you might have got a good batch, ive seen people have no end of problems with extrusion when they need precision fitting
[06:57:44] <sensille> ok, they're from misumi, with a crazy packaging overkill
[06:58:19] <XXCoder> jthornton: odd hope you find why
[06:58:26] <gloops> if your 4ft gantry has a 2mm bow youve got major problems - you cant cut a straight line lol
[06:59:26] -!- emsjessec has joined #linuxcnc
[07:02:21] <jthornton> just isolating that bit of code now to sort it out
[07:03:28] <XXCoder> sigh read something that made me feel sick because it could happen to me
[07:04:08] <XXCoder> police stopped a van, went out, talked and apparently shouted few times to show hands, opened door and took driver out and very seriously beat him
[07:04:19] <XXCoder> he was trying to tell police that hes deaf
[07:04:55] <sensille> next you need a sign on the window :(
[07:04:55] <XXCoder> sadly not first time, but in least this guy lives this time. theres couple of police murder of deaf people
[07:05:03] <XXCoder> sensille: thats the thing. why?
[07:05:17] <sensille> because U.S.?
[07:05:24] <XXCoder> because he had sign
[07:05:34] <XXCoder> still hes beaten and hospitalized
[07:06:23] <XXCoder> large percent of police shootings at stops is deaf unfortunately
[07:06:26] <XXCoder> so could happejn to me
[07:06:55] <XXCoder> worse one there was deaf driver and his son
[07:06:56] <sensille> how can the public tolerate the US police?
[07:07:10] <XXCoder> son was hearing so he told police that driver is deaf, blam blam
[07:07:31] <XXCoder> police didnt listen to driver son, which is also adult
[07:07:54] <XXCoder> previous one I talked about hes 64 years old. not exactly a threat to [police
[07:09:32] <XXCoder> sensille: really it depends on where and training
[07:09:39] <XXCoder> washington west end seems good on this

[10:08:07] <treats> Hi all, new to cnc so my assumptions may be a bit off-base. I'm looking to cnc hardwood. I'm trying to find a bit without any luck. Could someone either point me toward a bit or inform me why I'm not thinking correctly?
[10:08:25] <treats> 1/8" or smaller diameter, 1" or more depth, no taper. Up or down is a-okay.
[10:10:20] <sync> 8x the diameter is not easy
[10:10:41] <sync> you can clearance a bit at the shank tho
[10:13:41] <treats> So look for a shank less than 1/8"?
[10:14:39] <sync> no
[10:15:50] <treats> I understand the 8x comment, but not the clearance comment.
[10:19:46] -!- weenerdog has quit [Remote host closed the connection]
[10:20:03] -!- weenerdog has joined #linuxcnc
[10:20:12] <sync> well, you still have 1/8 where you clamp it bit in between it is a weee bit thinner
[10:20:14] <sync> so it does not rub
[10:20:26] <sync> when you go past the cutting edges
[10:22:12] <gregcnc> necked
[10:25:16] <gregcnc> maybe http://www.harveytool.com
[10:25:23] <Rab> treats, "real" industrial tooling with that much stickout might be a little exotic and pricey. But I can tell you that Rotozip make very long up- and down-cut bits, some of which are 1/8" dia: https://www.rotozip.com
[10:26:10] <Rab> Those bits are HSS IIRC, so they're quite flexible...prob need a low feed rate.
[10:26:16] <gregcnc> those were the first to come to mind, but HSS that long...
[10:27:58] <gregcnc> I probably did cut some MDF with those as first cuts in my CNC in 2004 or so.
[10:29:36] <Rab> I used them to bootstrap a Rotozip mount in plastic: http://reboots.g-cipher.net
[10:30:39] <Rab> Unfortunately the only tool I had was downcut, and even with a relief channel underneath the cut packed full of chips. It was pretty bad. But successful! http://reboots.g-cipher.net
[10:30:43] -!- veek has quit [Quit: Leaving]
[10:32:26] <Rab> McMaster-Carr option, cheaper than some: https://www.mcmaster.com
[10:34:12] <Rab> 1/8" is the smallest they have in 1" length of cut.
[10:40:30] -!- gloops has quit [Ping timeout: 250 seconds]
[10:41:57] -!- phiscribe_ has joined #linuxcnc
[10:49:57] <treats> Nice find Rab
[10:53:32] <treats> Also, being new, both of those bit sources are helpful. I was relying on Amazon and Toolstoday.
[10:53:46] <ziper> i've been looking for something similar too
[10:53:49] <ziper> but for foam cutting
[10:54:06] <treats> toolstoday has bits that match my needs for foam.
[10:54:09] <treats> FYI
[10:55:12] <Rab> This might be appropriate for hardwood, 1.5" length of cut: https://www.ebay.com
[10:55:56] <treats> And the price is nice too... Might grab one now
[10:55:57] <Rab> That eBay seller (drillman1/Carbide Plus) is legit. Quality products and fast service. https://www.ebay.com
[10:56:56] <Rab> I recommend scanning through his listings. I didn't see 1/8" x 1" at a glance, but that might be cheaper and more robust.
[10:56:58] -!- c-log has quit [Ping timeout: 250 seconds]
[10:57:58] <Rab> He has a bunch of single flute and downcut bits suitable for foam and plastic, too.
[10:59:43] <Rab> Bingo, here's the same 3-flute end mill in 1" for cheaper: https://www.ebay.com
[10:59:53] -!- c-log has joined #linuxcnc
[11:00:35] <Rab> I don't know the applicability of 3-flute high-helix for hardwood, but it seems like it would be a good match.
[11:00:42] -!- gloops has joined #linuxcnc
[11:00:44] <Rab> And stronger than 2-flute.
[11:01:17] <gloops> i use the chino 3.175mm spirals on oak, theyre sound
[11:01:59] <Rab> Be aware that long 1/8" carbide like that will be very prone to breaking.
[11:03:52] <gloops> cant remember seeing them with 25mm cut, i think mine are 22mm
[11:04:31] <treats> Thanks for the tips guys. Big help.

[11:12:30] <Tom_L> jthornton, feel free to fix my java issue when you finish
[11:13:19] <Tom_L> importing a .csv file to it with a few 'special' characters screws it all up
[11:13:28] <Tom_L> like ' " \ etc
[11:17:48] <weenerdog> can you just toss the special chars or do you need them imported?
[11:18:02] <Tom_L> they're part of the data set
[11:18:13] <Tom_L> i'm going to remove them to test but they need to be there
[11:20:15] <weenerdog> when you write them are you concatenating strings? and are you using escape chars?
[11:20:35] <Tom_L> no esc characters yet
[11:21:02] <weenerdog> like... read a char, see if its a comma yet, write a char?
[11:21:29] <Tom_L> the import code doesn't do that yet but that's what i'm getting ready to fix
[11:21:58] <Tom_L> i just don't know java or what format it wants on those cases yet
[11:22:15] <Tom_L> the export code is c / pascal
[11:22:45] <weenerdog> it wants you to refer to them as escape characters. like " is \", \ is \\, ' is \'
[11:22:50] <Tom_L> i'm sure i can fix it, it's just a pain in the ass
[11:22:57] <weenerdog> nah not bad
[11:23:16] <Tom_L> so the next char after the \ is the one you want
[11:23:21] <weenerdog> yes
[11:23:39] <Tom_L> what are all the special characters affected? ' " \ and what else?
[11:23:45] <weenerdog> it says, for example, i really want to stick a double quote here, not end the string
[11:23:52] <Tom_L> i don't think the data has anything else but maybe those
[11:24:10] <weenerdog> https://www.javatpoint.com
[11:24:13] <Tom_L> that's easy enough to fix
[11:24:19] <weenerdog> thats a list of them
[11:24:52] <weenerdog> should just be backslash, single quote, double quote, question mark in your case
[11:25:19] <Tom_L> so really all i need to do when i encounter one is to add the \ ahead of it in the string
[11:25:28] <weenerdog> si senor
[11:26:04] <Tom_L> fscking java....
[11:26:19] <weenerdog> hehehe
[11:27:29] <Tom_L> it seems to accept the crlf ok
[11:27:39] <Tom_L> chr 13 chr 10
[11:27:56] <weenerdog> i dunno i'd have to read the code
[11:28:19] <Tom_L> well those import ok far as i can see
[11:30:15] <weenerdog> just hammer in code to check for ' " \ and ?, replace with \' \" \\ and \? respectively and see if it boogies
[11:30:33] <Tom_L> i plan to
[11:30:48] <jthornton> Tom_L: java lol
[11:31:24] <Tom_L> probably worse than brainfuck
[11:31:45] <weenerdog> it aint the kitchen... its the cook :)

[11:37:15] <treats> Another question. I'm going to need a new collet and I know this will work: https://vicious1-com.myshopify.com
[11:37:33] <treats> But I'm wondering if I can get away without the housing and get this: https://www.amazon.com
[11:38:23] <gregcnc> the collet must match the tool it's going into. Those don't look like the same part
[11:39:41] <treats> Yeah, I'm reading the comments on the page I linked too *facepalm*
[11:39:45] <weenerdog> i tink its the same collet, the 2nd one just doesn't have the nut

[12:36:19] <dasbrow> Hi Everyone, I can't figure out how to adjust my TPI for my z axis. I used JT's 7i96 python configuration tool to generate the files. X and Y are fine, they have a TPI of 8, the Z has a tpi of 10. Thanks.
[12:37:10] <JT-Shop> really you used my 7i96 configuration tool?
[12:37:45] <dasbrow> yes, why is that a bad idea or are you just yanking me?
[12:38:21] <JT-Shop> no, this is the first time I've seen anyone that used it
[12:38:53] <JT-Shop> let me catch up to you
[12:38:54] <dasbrow> well I am a noob when it comes to setting up these things so I figured use a tool lol
[12:39:07] <JT-Shop> that's what it is for
[12:39:44] <JT-Shop> let me see if it is on this PC or not... I may have to set it up to see
[12:43:18] * fragalot is wondering if he's better off with a high quality standard boring head, or a vertex universal
[12:44:08] <JT-Shop> dasbrow: I'll go down to the beer cave PC where I have it installed
[12:44:42] <dasbrow> ok thanks
[12:50:32] <JT-Shop> dasbrow: looks like the spindle page is missing the scale entry
[12:51:12] <JT-Shop> opps nevermind you said Z
[12:51:54] <JT-Shop> the Scale setting for each axis is the number of pulses per user unit if that makes sense
[12:57:34] <dasbrow> yes, I think I figured it out, I was setting scale = 4000 for all XY (10tpi) and was going up for Z, my Z is actually 8tpi. I am closer at SCALE = 3200. I may have this part.
[12:59:07] <JT-Shop> that sounds like 200 pulse/rev * 2 micro step * 8 TPI
[13:01:28] -!- phiscribe has joined #linuxcnc
[13:02:02] <dasbrow> Ha I was wrong again, it's 6tpi. Sad as I had this all set up when I was using a cheap bob. Thanks.
[13:02:41] <JT-Shop> hey I'm glad to hear someone used the configuration tool... makes me want to add more to it now

[13:14:33] <dasbrow> JT-Shop: a few things, I need to hack it to allow SERVO_PERIOD = 500000 (it would not allow me to go over 100000), MAX_VELOCITY and MAX_ACCELERATION, should be allowed to be floating point numbers. Unless I have set up things wrong. On my Z I need both to be 0.2 or the stepper stalls out.
[13:14:47] <dasbrow> *needed
[13:15:02] <gregcnc> eck 500,000 won't run though

[13:16:29] <gregcnc> oh well mesa can deal with it, but still surprising

[13:28:31] <JT-Shop> dasbrow: did you discover the F1 help context for each tab?
[13:28:58] <dasbrow> No, probably should look at that.
[13:31:09] <JT-Shop> probably not a great deal of help but looks like I need to add something saying it's there
[13:32:16] <dasbrow> You've done a good job, as I said I am a noob, and have limited time. I am rushing to get this mill done so I can use it. Thanks for all your help.
[13:33:17] <JT-Shop> your just the person I wrote that for someone new to LinuxCNC and Mesa
[13:33:48] <JT-Shop> if you have anymore feedback feel free to holler at me here or in the beer cave i'm jthornton

[14:03:18] <Tom_L> JT-Shop, just parsing some data
[14:03:39] <Tom_L> java doesn't like it
[14:05:06] <JT-Shop> why use java?
[14:05:28] <fragalot> at least you don't have to do it in C on a controller with only 16K of RAM.
[14:05:40] <Tom_L> it's a damn phone app i import data to
[14:06:04] <Tom_L> i didn't write it
[14:07:21] <Tom_L> so i'm writing a funciton to add the esc codes to the ones it burps on
[14:07:58] <JT-Shop> ah
[14:08:34] <Tom_L> it writes a .cvs file and excel will import it fine but the phone app misses a good percent of the data on import
[14:08:55] <Tom_L> *csv
[14:10:28] <fragalot> probably messes up on numbers

[14:13:09] <fragalot> fun stuff
[14:13:54] <CaptHindsight> if someone in the USA says they need xML or something do they mean mL (mililiters) or M=1,000 Liters?
[14:14:16] <CaptHindsight> or/of
[14:14:49] <Rab> Almost certainly milliliters.

[14:15:42] <cradek> with six orders of magnitude between the two answers, you can probably use context to answer your question

[14:16:21] -!- JesusAlos has quit [Quit: JesusAlos]
[14:16:31] <fragalot> CaptHindsight: weeb. ML == MEGA liters.. 1000000 liters.
[14:16:51] <CaptHindsight> yeah, context doesn't help and yeah they could mean M = Mega

[14:20:53] -!- DaPeace has quit [Quit: Leaving.]
[14:21:01] * fragalot heavily invests in the stock market
[14:21:04] <cradek> I promise you nobody, even in the US, would write ML to mean 1000 litres
[14:21:33] <cradek> not since 1950 anyway
[14:22:49] <fragalot> cradek: not ever
[14:22:57] <fragalot> ML is not 1000, even if used correctly
[14:23:01] <cradek> and I really suspect you can tell from context whether they mean mL or ML
[14:23:05] <CaptHindsight> I come across it from time to time, I'll know in a few minutes
[14:23:41] <cradek> fragalot: it has been used that way a lot in the US, I've seen it on many (old) schematics
[14:24:16] <cradek> M for micro, MM for pico, and M for kilo (srsly)
[14:24:28] <cradek> but again you can just use the context to figure it out
[14:27:31] <gloops> they were printing plastic face inserts on tv earlier, for people with injuries or deformities, fairly straightforward process all done on site in hospital, scanning head, designing new parts, printing, cost per part £10 - no need to contract the making out
[14:27:42] <gloops> this cost tens of thousands before
[14:27:49] <cradek> fragalot: I found a schematic showing it in two tries: http://bama.edebris.com
[14:28:11] <cradek> notice MFD, MMFD capacitors, 330M OHM resistors
[14:28:59] <cradek> hahaha also 9 MC frequency
[14:28:59] <CaptHindsight> heh they meant mL
[14:29:13] <fragalot> cradek: :'(
[14:29:14] <cradek> so in one table M is micro, kilo, mega
[14:29:35] <Rab> cradek, none of those examples are 1000.
[14:29:44] <cradek> yes the resistors are
[14:30:14] <cradek> R1 330M OHM is 330k
[14:30:38] <CaptHindsight> so apparently someone was selling something that cost few $/L for $1,000's
[14:30:45] <Rab> OK, on second thought, 330 megaohm resistor seems unlikely.
[14:30:52] <cradek> see! context!
[14:30:54] <cradek> :-)
[14:32:11] <cradek> fwiw this one is 1941
[14:32:20] <Rab> It helps that they spell out "megohm" for those cases.
[14:33:20] <cradek> yes it would be madness otherwise hahahaha
[14:33:46] <cradek> this is confusing let's pick one of the four to spell out! but ... only when it's a resistance and not a frequency
[14:34:38] <Rab> Other noteworthy cases: "1000 OHM" "1 MEGOHM"

[14:35:45] <cradek> sometimes you encounter lowercase omega for ohms too, but rarely
[14:39:58] <Rab> That's a pretty good sized building.
[14:40:41] <Rab> Probably full of all kinds of nice things. Backs up to an elementary school. :P
[14:41:28] <CaptHindsight> Zenith was a giant co until the early 80's
[14:41:55] <CaptHindsight> they radio then TV then computers
[14:42:06] <CaptHindsight> they started in radio
[14:44:01] <Rab> Even had a Soviet knockoff, ИADIR.
[14:47:14] <gregcnc> Ml is not a valid unit?
[14:48:15] <jdh> anyone use form thread/roll taps? do they need different size drill holes?
[14:48:24] <fragalot> they do
[14:48:33] <fragalot> depends on the material too
[14:48:35] <cradek> yes form taps need their own starting hole sizes
[14:48:47] <cradek> it's critical and sometimes you might even want to ream the start hole
[14:50:12] <jdh> Any better or worse for rigid tapping? I assume the threads are better.
[14:53:17] <fragalot> never used them rigid personally, but I don't see why they'd be worse if your hole is the right size
[14:53:39] <gregcnc> you have to run them slower, that's all
[14:54:15] * Loetmichel noticed today that a CNC 6040 isnt really rigid enough to do a 6mm ball end mill 5.8mm deep in aluminium... even if one does rough down the slot beforehand in 4 steps with a 3mm end mill... MAAAN was that thing chattering (no problem though, just have to put a bit more heat conductive goo around the heatpipes those slots is for than planned)
[14:54:38] <fragalot> Loetmichel: lol
[14:54:54] <fragalot> get yourself a schaublin. I don't think anyone ever told that machine the concept of "chatter"
[14:55:45] <Loetmichel> fragalot: i doubt my hobby room floor will stay in place... its only rated for half a ton per square meter.
[14:55:57] <Loetmichel> (and there is a cellar underneath)
[14:56:04] <Loetmichel> apart from that i have no room for one
[14:56:08] <fragalot> it's only 800kg.. leave it on the pallet :Pµ

[14:57:17] <gregcnc> for the madmax times?
[14:57:25] <Loetmichel> D480
[14:57:37] <fragalot> yea.. I can't move that thing on my own
[14:57:51] <fragalot> the 250x550 lathe and RF45 I could carry out alone
[14:58:11] <Loetmichel> the lathe has only 70kg and the CNC 6040 is about 40kg with all peripherials
[14:58:12] <Loetmichel> ;)
[14:58:35] <Loetmichel> the D480 is 480mm between centers
[14:58:48] <Loetmichel> it was very funny when i got it (used)
[14:58:50] <fragalot> minimum useful size, imho :-)
[14:59:13] <Loetmichel> the seller was a mountain. 1 head bigger than me and a good bit more wide
[14:59:21] <fragalot> I wouldn't mind a beefy larger swing lathe, but they don't come in "stub length"
[14:59:28] <Loetmichel> he said: how do you get that thing out of the cellar?
[14:59:41] <gloops> i have put wheels on a bandsaw and table saw
[14:59:58] <Loetmichel> $me "if you open the doors for me: Like this"... grabbed it and carried it out the cellar...
[15:00:04] <Loetmichel> he couldnt believe it...
[15:01:03] <gloops> theres one drawback with that Loetmichel - if you can carry it away, so can a burglar
[15:01:11] <fragalot> Loetmichel: that's how I got the 250x550 up to the attic :-) (all 125kg of it)
[15:01:23] <Loetmichel> http://www.cyrom.org <- that little thing there
[15:01:36] <fragalot> but truth be told.. had it been 1 step further.. I wouldn't have made it
[15:01:46] <Loetmichel> fragalot: i know that feeling ;)
[15:02:16] <Loetmichel> i hope you used some straps or a hand truck though
[15:02:19] <fragalot> cheat! you took the slide off :D
[15:02:31] <Loetmichel> that 70kg lathe was about the max i could carry
[15:02:36] <fragalot> I had a safety line on it but couldn't keep tension on it
[15:02:43] <fragalot> so still had to lift the damn thing

[15:03:01] <Loetmichel> nope, that came off afterwards, the motor was/is bad

[15:03:44] <fragalot> the capacitor on mine blew about 3 months after I got it
[15:03:58] <fragalot> replaced the motor with a siemens & VFD.. best upgrade ever.
[15:09:07] <Loetmichel> same
[15:09:24] <Loetmichel> just not a siemens buit a local manufacturer

[18:42:38] <jthornton> hamsters I'll let you borrow my cat for steppers the 7i96 is great
[18:42:55] <weenerdog> sweet. good cat?
[18:43:07] <jthornton> yep a lap cat
[18:43:20] <weenerdog> my cat got killed by a bear in the spring :(
[18:43:40] <weenerdog> he was a lap cat inside, killing machine outside. big yellow one.
[18:43:45] <jthornton> I'm so glad black bear is rare around here
[18:44:24] <weenerdog> they're like rats here
[18:45:11] <weenerdog> first time its down in the teens this year i think. 18 and dropping

[18:46:28] <ChunkyPuffs> anybody got a feeds n speeds calculator that's relevant for a noobie/
[18:46:36] <ChunkyPuffs> trying to cut aluminium with a 2 flute
[18:46:55] <Tom_L> start with a .001" chip load
[18:47:05] <Tom_L> on that machine
[18:47:06] <roycroft> The Internet(tm) has all that stuff
[18:47:53] -!- heinz_ has quit [Ping timeout: 256 seconds]
[18:52:08] <ChunkyPuffs> I don't know what a .001 chip load means Tom_L
[18:52:12] <ChunkyPuffs> I'm using fusion 360
[18:52:15] <ChunkyPuffs> I'm using Kinetic NC
[18:52:27] <ChunkyPuffs> I am not using LinuxCNC, so it' a problem in language, I eventually want to, but I can't right now
[18:53:42] <Tom_L> i explained that to you the other day
[18:54:14] <Tom_L> The chip load is a measurement of the thickness of material removed by each cutting edge during a cut. This is a valuable piece of information that can then be used to calculate new set ups. Calculation are as follows: Chip Load = Feed Rate (inches per minute) / (RPM x number of flutes).
[18:54:50] <Tom_L> so i suggested you start with a .001" chip load
[18:55:36] <Tom_L> or .025 mm
[18:56:39] <ChunkyPuffs> yes Tom_L, I have no idea how to actually set or make thi shappen
[18:56:46] <ChunkyPuffs> I know what it is in theory, but not how to adjust it
[18:57:11] <Tom_L> fusion should have a place to enter the chip load
[18:57:25] <Tom_L> then you enter the rpm and or the feed and it will calculate the other
[18:57:38] <ChunkyPuffs> Right, maybe
[18:57:44] <ChunkyPuffs> I will take a look
[18:57:49] <ChunkyPuffs> but as for a calculator, is there one?
[18:57:51] <Tom_L> so the calculator is built in fusion
[18:57:56] <Tom_L> there are hundreds of them
[18:58:15] <Tom_L> https://www.google.com
[18:59:27] <Tom_L> https://daycounter.com
[19:00:09] <ChunkyPuffs> what is "surface speed" in this calc?
[19:00:31] <Tom_L> depending on the tool diameter it is the speed of the cutter at the blade
[19:00:52] <Tom_L> so at 1000 rpm the surface speed of a 1" cutter will be higher than a 1/4" cutter
[19:00:55] <ChunkyPuffs> 2mm 2 flute carbide bit
[19:01:10] <Tom_L> because it's further away from the center
[19:02:17] <Tom_L> generally that's a more important number on a lathe than a mill
[19:06:47] <ChunkyPuffs> right, none of this makes it easy for me to get cutting
[19:07:07] <ChunkyPuffs> there ought to be a calculator that makes this easy, instead of explaining the formulas to me.
[19:07:20] <ChunkyPuffs> I get the formulas, but really I want to get cutting.
[19:07:37] <ChunkyPuffs> I'm not afraid to break the bit
[19:07:55] <ChunkyPuffs> some manufacturers provide you with feeds n speeds out of the box, this doesn't have to be this hard.
[19:10:07] <weenerdog> theres loads of online speed & feed calculators, chunky
[19:10:23] <ChunkyPuffs> Right, but is it really as slow as they suggest

[19:12:38] <ChunkyPuffs> tell me what I have gotten wrong here
[19:14:13] <SpeedEvil> slow?
[19:14:38] <SpeedEvil> 2mm is a damn tiny endmill is the roblem
[19:15:05] -!- Loetmichel has joined #linuxcnc
[19:15:50] <ChunkyPuffs> SpeedEvil, what I'm cutting is small, I don't get it
[19:16:47] <andypugh> What is slow?
[19:17:00] <ChunkyPuffs> well, my machine max is 30,000 rpm
[19:17:02] <SpeedEvil> 1m/min isn't very slow
[19:17:06] <ChunkyPuffs> but I don't want to cut at 30,000 rpm
[19:17:09] <ChunkyPuffs> I didn't set 1m/min
[19:17:19] <ChunkyPuffs> I don't understand what I'm supposed to be setting
[19:17:21] <SpeedEvil> the calculated result was that.
[19:17:54] <andypugh> 275m/min seems fast.
[19:18:21] <andypugh> But then I run slow typically.
[19:18:29] <ChunkyPuffs> I want to run safe for the bit
[19:18:31] <ChunkyPuffs> so I don't get it
[19:18:40] <ChunkyPuffs> I don't get how to calculate the cutting speed
[19:19:20] <andypugh> It’s based on the tool material and the workpiece material.
[19:20:11] <ChunkyPuffs> aluminium, carbide
[19:20:15] <ChunkyPuffs> I didn't set it, it was set for me automatically
[19:20:19] <ChunkyPuffs> how do I figure out a sane value
[19:20:27] <andypugh> So, 275 is probably about right.
[19:20:35] <andypugh> (Possibly low)
[19:20:52] <SpeedEvil> That is a sane value, pretty much. You could back off the chip load by half, and half the RPM
[19:20:53] <andypugh> But that’s as high as you can get with a 2mm tool and a 30,000 rpm spindle
[19:21:00] <ChunkyPuffs> I don't want to run the spindle at max
[19:21:02] <SpeedEvil> that would quarter your cut speed
[19:21:04] <ChunkyPuffs> I don't have the coolant for that
[19:21:16] <sync> you want to run it at full rip
[19:21:20] <sync> with such a small mill
[19:21:23] <SpeedEvil> but probably that
[19:21:27] <andypugh> I think that with a 2mm you _do_ want to run at max
[19:21:33] -!- m0n5t3r_ has quit [Read error: Connection reset by peer]
[19:21:33] <SpeedEvil> Indeed.
[19:21:36] <ChunkyPuffs> https://cdn.discordapp.com
[19:21:45] <ChunkyPuffs> You're not getting it, that isn't calculated
[19:21:50] <ChunkyPuffs> I'm asking how to figure out a sane value
[19:22:00] <ChunkyPuffs> that is a manually changed variable, and you're suggesting it's sane
[19:22:10] <ChunkyPuffs> if I change the rpm, that doesn't change, how do I find out a sane vlaue
[19:22:12] <ChunkyPuffs> value*
[19:22:29] <andypugh> What makes you think that these are not sane values?
[19:22:55] <ChunkyPuffs> because default does not equal safe
[19:23:04] <andypugh> You will note that for the same surface speed at 10,000 rom your feed rate is now much lower?
[19:23:04] <ChunkyPuffs> and halving the rpm, but cutting at the exact same fucking rate, doesn't see mright
[19:23:17] <andypugh> No, hang on, that’s not right
[19:23:20] <ChunkyPuffs> but the cutting rate is the same
[19:23:20] <ChunkyPuffs> wtf
[19:23:52] <andypugh> What happens if you put the machine max up to 100,0000
[19:24:49] <andypugh> 30,000 rpm with a 2mm cutter is 188 m/min
[19:25:03] <ChunkyPuffs> https://cdn.discordapp.com
[19:25:34] <andypugh> There you are, it takes 43,000 rpm to reach your target surface speed
[19:26:17] <andypugh> So, anywhere below 43,000 the calculator is ust going to say “turn it up to 11”
[19:26:57] <andypugh> (it’s a pity that it doesn’t adjust-down the surface speed to make this more obvious)
[19:26:59] <ChunkyPuffs> dude, I don't get it
[19:27:05] <ChunkyPuffs> all I want to do is get a sane value for my cutting
[19:27:07] <ChunkyPuffs> I don't want to go fast
[19:27:22] <andypugh> all the values so far seem sane
[19:27:51] <andypugh> The point is that a 2mm cutter would ideally by used in a faster spindle
[19:28:28] <ChunkyPuffs> no coolant
[19:28:30] <ChunkyPuffs> remember that
[19:28:43] <ChunkyPuffs> I want to practice on aluminium and have compressed air, that's it
[19:28:58] <andypugh> But, if you don’t want to run at 30,000 then the suggested feed rate at 10,000 was 360mm/min. Though with a tiny 2mm end mill I probbaly would only go at half that
[19:29:16] <ChunkyPuffs> what do you mean probably
[19:29:19] <ChunkyPuffs> this is supposed to be a science
[19:29:25] <ChunkyPuffs> that's why I'm asking for a calculator ffs
[19:29:29] <sync> you don't need coolant to go fast
[19:29:34] <ChunkyPuffs> this isn't about estimates, that's why it's calculated
[19:29:43] <sync> it is about guesstimates
[19:29:51] <ChunkyPuffs> I'm asking for calculations, how to do it, etc, not vague feed and speed recommendations, ACTUAL facts about the material
[19:29:59] <ChunkyPuffs> it is **not** about guesstimates
[19:30:03] <sync> it is
[19:30:05] <ChunkyPuffs> and all you're doing is misleading me when you say this
[19:30:16] <ChunkyPuffs> That's not how it's done by any manufacturer
[19:30:16] <andypugh> Well, I have coolant, but only have a 1000 rpm spindle, so I am not really able to run 2mm tools anywhere near the right speeds.
[19:30:27] <sync> that is how it is done by the tool mfgs
[19:30:36] <ChunkyPuffs> You will continue to break bits your entire life if you say that sync
[19:30:37] <sync> look at the range of feeds and speeds they give you for each material
[19:30:48] <ChunkyPuffs> it's about tolerances, that's why your tol manufacturer will give you them when you buy their tools
[19:30:50] <ChunkyPuffs> if they're any good
[19:30:59] <ChunkyPuffs> Exacts, no range for guessing
[19:31:03] <ChunkyPuffs> you're misleading me, badly.
[19:31:14] <sync> so why do I twiddle my feed override knob on every job?
[19:31:34] <sync> to find where the part and machine is happy?
[19:31:38] <andypugh> This table says anywhere from 200 to 600 for high silicon aluminium. And that is assuming coolant.
[19:31:41] <andypugh> https://www.itc-ltd.co.uk
[19:31:44] <sync> when it is an exact science that I could have found out before?
[19:32:16] -!- jerryq has joined #linuxcnc
[19:32:52] <ChunkyPuffs> sync, There's a mathematician who works for autodesk at my makerspace who suggests what you're doing is retarded
[19:33:00] <andypugh> But I am also thinking that the chip load in that calculator looks a bit big for a tiny cutter. I am not sure that it is considering tool forces, just surface speed and a generic chip load
[19:33:05] <ChunkyPuffs> And has spent the last hour convincing me of the science behind it
[19:33:30] <andypugh> So, get that bloke to tell you what feed and speed to use, rather than asking us for avice
[19:33:34] <ChunkyPuffs> but had to go, so here I am asking for advice and being told it's not a science
[19:33:42] <ChunkyPuffs> he had to go, and I'd prefer not to waste his time
[19:33:46] <ChunkyPuffs> but the blatant mislead is annoying
[19:33:52] <andypugh> So you are wasting our time instead?
[19:34:01] <sync> it's not a mislead, it is just the reality of it
[19:34:12] <andypugh> (By asking for advice, then telling us we are wrong)
[19:34:40] <ChunkyPuffs> It is not a matter of estimation
[19:34:50] <ChunkyPuffs> it is a matter of formula, and I'm just asking if there's a calc for the formula
[19:35:03] <andypugh> Ii is when you say “I don’t want to run that fast” and “I have no coolant”
[19:35:11] <ChunkyPuffs> and if you don't think it's a matter of formula, you're ignoring the manufacturers you're buying bits from, who sometimes give you the exact tolerances of the tool

[19:35:32] <MarcelineVQ> Did you ask your manufacturer?
[19:35:34] <sync> the tolerance of my tooling has nothing to do with the speeds i run it at

[19:36:00] <SpeedEvil> Tool manufacturers specify speeds and feeds for good machines in good conditions.
