[00:00:15] <XXCoder> wish I had it, save time on building that ragon :P
[00:00:19] <XXCoder> dragon
[00:00:31] <chris_99> heh
[00:00:37] <Kevin`> are there any better value low end cnc mills than these? http://www.omiocnc.com/x6-2200l-3a/

[00:01:05] <XXCoder> thats just rebuild from aliexpress I bet
[00:01:15] <XXCoder> you can buy direct but then you gonna fix some issues

[00:03:46] <Kevin`> I wouldn't mind redoing electronics a little.. probably have to for at least that usb card since it's mach-only, but I don't want to have to work around mechanical problems
[00:05:21] <XXCoder> my recommand is look at aliexpress foe similiar machines
[00:05:27] <XXCoder> and see if its worth it or not
[00:05:42] <XXCoder> I guess its in least $500 less, or more
[00:05:47] <Kevin`> people aren't big on vendor reviews for aliexpress
[00:05:59] <XXCoder> though less options than that listed item on way of accessories
[00:09:27] <Kevin`> I can't quickly find any machines on aliexpress with equivalent specs.. similar looking, but different axis and different spindle

[00:11:37] <XXCoder> hmm yeah aliexpress ones isnt too great
[00:11:43] <XXCoder> but an option
[00:29:42] <tiwake> dodododo
[00:30:20] <tiwake> did another batch of anodizing
[00:30:31] <tiwake> my red casswell dye really sucks

[02:05:17] <Erant> If I want ease of machining, should I use O-1 or W-1?
[02:06:45] <XXCoder> w-40 heh
[02:06:58] <XXCoder> honestly not too sure what you mean by "ease of machining"
[02:07:41] -!- PetefromTn_ has quit [Ping timeout: 276 seconds]
[02:07:48] <Erant> Machinability. I'm going to turn some rod down in my mill, so.
[02:08:15] <XXCoder> ahh w-40 can definitely work for that but not too sure if it is best way to do so.
[02:08:38] <XXCoder> just go to car tools store and grab few cans of wd-40
[02:08:58] <XXCoder> though there is non-spraying variant that you can add to sprayer
[02:09:03] <XXCoder> better for envorment
[02:09:38] -!- PetefromTn_ [PetefromTn_!~IceChat9@75-136-59-160.dhcp.jcsn.tn.charter.com] has joined #linuxcnc
[02:10:14] <Erant> I meant O1 or W1 steel.
[02:10:26] <Erant> O1 being drill rod, basically.
[02:10:49] <Erant> I seem to recall O1 having better machinability than W1.
[02:10:49] <XXCoder> ahh misunderstood you
[02:11:04] <XXCoder> I dont know much about materials unfortunately
[02:11:34] <Erant> Me neither, just seem to remember something along those lines from a YouTube video.
[02:12:45] <Erant> Going to take some drill rod and see how well my mill works as a lathe :)
[02:13:28] <XXCoder> yeah can always buy more stock if needed.
[02:13:53] <Crom> I saw want a mill! 3040 is total crap!!
[02:13:58] <Crom> s/saw/so/
[02:14:09] <XXCoder> Crom: sell me your 3040 lol
[02:14:12] <Erant> I thought about the 3040.
[02:14:16] <XXCoder> cnc router right?
[02:14:24] <Crom> engraver
[02:14:26] <Erant> But it most certainly would not work as a lathe.
[02:14:57] <XXCoder> Erant: one of projects I planned to do is direct mount of wood rod to stepper for 4th axis
[02:14:59] <Crom> it would actually, just not on anything close to iron or even steel
[02:15:31] <XXCoder> it wont be very high accuracy and precision, but it would work for basic tests and maybe basic stuff
[02:16:38] <Crom> I would love to use my headstock back gear to mount a servo motor to, and cnc everything else.
[02:17:07] <Erant> Crom: Well, if I recall correctly, the 3040 has ER11 collets
[02:17:08] <XXCoder> Crom: it works fine on alum?
[02:17:18] <Erant> I'm doing 3/8" drill rod
[02:17:26] <Erant> Which juuust fits in the ER16 collet.
[02:17:36] -!- PetefromTn_ has quit [Quit: I'm Outta here!!]
[02:17:41] <Crom> it works on AL, just not fast or good
[02:17:59] <Crom> yes ER11
[02:22:25] <Erant> My SX1P does Al well, and steel ok.
[02:23:04] <Erant> Crom: Right, so I'm using a technique whereby you chuck the material in the collet rather than the tool.
[02:23:23] <Erant> Which allows you to do some limited lathe-style operations
[02:24:01] <Erant> Tool goes in a vice or something. Affixed to the table.
[02:24:45] <Crom> I'm thinking about a Bolton ZX45
[02:28:18] <Crom> and if my VA check is big enough a Grizzly Lathe 11" x 26" G9972Z, which lets me use my Sheldon 4 jaw chuck
[02:29:12] <Crom> tail stock is a MT3, but I can get an adapter to use my MT2 stuff
[02:29:50] -!- Camaban has quit [Quit: Leaving]
[02:29:58] <Crom> first thing you do with a G9972Z is add a reverse tumbler
[02:31:25] <Crom> erant, I've done milling with my lathe, though I don't have a collet setup for it, so I hold the end mill in the 4 jaw chuck

[04:00:29] <zeeshan> finally ive learned mastercam better.
[04:00:37] <zeeshan> little to no air cutting with dynamic tool paths
[04:00:41] <zeeshan> makes contouring obsolete
[04:00:48] <zeeshan> http://i.imgur.com/akA0vq9.png
[04:00:49] <zeeshan> example
[04:01:13] <zeeshan> i think hsm works calls it adaptive cleaning
[04:01:59] <zeeshan> absolutely no sharp corners in the tool path
[04:02:10] <zeeshan> (when cutting)
[04:15:28] <Wolf_> nice
[04:17:16] <XXCoder> so it makes parts more smooth or?
[04:17:22] <XXCoder> or just more effecient?
[04:17:49] <zeeshan> more efficient
[04:18:02] <zeeshan> to give you an idea
[04:18:05] <zeeshan> i went from 12ipm
[04:18:08] <zeeshan> to 50 ipm..
[04:18:28] <zeeshan> also sharp corners are very bad for small end mills
[04:18:31] <zeeshan> they snap em :P
[04:18:43] <zeeshan> sharp tool path corners that is
[04:18:50] <zeeshan> cause if yo utry to imagine it
[04:19:11] <zeeshan> at the exact corner, the about 3/4" of the cicumference of the tool makes full contact
[04:19:27] <zeeshan> er..

[11:13:58] <aventtini> hello guys
[11:14:14] <aventtini> about the servo setup on the 2.7
[11:14:34] <aventtini> i can confirm there is a bug on the setup
[11:14:39] <aventtini> or some sort
[11:14:51] <aventtini> i will uplode the video whit 2.6
[11:14:59] <aventtini> same pins same settings
[11:15:08] <aventtini> and it works like a charm
[11:15:45] <aventtini> i did revers the AA5BB channels on the 2.7
[11:15:54] <aventtini> same result imposible to tune
[11:28:53] <witnit> aventtini: please do I am curious now!
[11:29:03] <aventtini> one sec
[11:29:24] <witnit> also upload those conf files
[11:32:35] <aventtini> same cables same setup
[11:32:53] <aventtini> encoder xyza
[11:33:03] <aventtini> sw 0123
[11:33:15] <aventtini> and machine on
[11:37:36] <aventtini> https://www.youtube.com/watch?v=GWJc8pEayWs
[11:37:39] <aventtini> done
[11:39:47] <archivist> a shaky video with no time to read anything is not helping
[11:39:48] <aventtini> no change what so ever on the cables
[11:40:37] <aventtini> sorry iphone is not so smart on the camera
[11:40:40] <aventtini> :)
[11:41:11] <aventtini> its a minimal setup done on the pnconf
[11:41:28] <aventtini> 4 encoders 4 SW and spindle
[11:41:32] <aventtini> pid 1
[11:41:32] <archivist> use the config off 2.6
[11:41:40] <aventtini> dot work
[11:41:43] <aventtini> dont work
[11:42:01] <aventtini> same problem
[11:42:31] <archivist> please your single line statements do not help people to help you
[11:43:22] <aventtini> you need the config files
[11:43:24] <aventtini> right
[11:43:31] <aventtini> i will get them tomorow
[11:44:02] <aventtini> its any way i can get the traj to 2.6?
[11:44:52] <aventtini> i can not make any mistake on the electronics
[11:44:55] <witnit> aventtini: did you do a new pncconf or did you copy your old WORKING configs manually?
[11:45:03] <aventtini> new
[11:45:11] <aventtini> new install new HDD
[11:45:33] <aventtini> i did not copy a single line or put someting in the ini
[11:45:42] <archivist> he did not copy the configs hence the problem
[11:45:55] <witnit> I highly suspect your new .hal and .ini is differing from what you had working in 2.6
[11:46:19] <aventtini> the only dif i so the 2.7 on FFerror was showing 0.0005 and i was thinking on inch
[11:46:23] <archivist> he has been told to use a diff program to find out what
[11:46:26] <aventtini> but setup is in mm
[11:46:45] -!- Tecan has quit [Quit: Live Long And Phosphor!]
[11:47:22] <witnit> why havent you copied your 2.6 configs exactly?
[11:47:26] <aventtini> i will get the hal and ini from a working machine
[11:47:38] <aventtini> i was testing as new instal
[11:47:42] <aventtini> to see if it works
[11:47:50] <aventtini> if a new instal on 2.6 works
[11:47:53] <aventtini> also a 2.7
[11:47:57] <aventtini> must work
[11:47:59] <aventtini> right
[11:48:01] <aventtini> same pins
[11:48:12] <aventtini> only 1 out machine on
[11:48:21] <aventtini> so no technical diff
[11:48:40] <archivist> we cannot know if any statement you say is right
[11:48:57] <aventtini> sure u are right
[11:49:28] <archivist> we dont know what you entered into pnconf
[11:49:45] <aventtini> on sec let me uplode
[11:53:40] <aventtini> i remaber i had pics
[11:53:42] <aventtini> :D
[11:54:44] <aventtini> http://imgur.com/a/UMeRA
[11:54:46] <aventtini> done
[11:55:34] <archivist> what are the values from 2.6
[11:55:50] <archivist> compare your hal and ini files
[11:57:09] <witnit> sorry aventtini but pictures are much less useful than .hal/.ini
[11:57:10] <aventtini> only diff is P is 50 FF1 is 1 and fferror min is 0.0005 amd max is 0.0500
[11:57:42] <aventtini> i did made same settings as on the pics to 2.6
[11:58:09] <aventtini> 2.6 has P=1 and ff1 is 0
[11:58:18] <archivist> and in the line above you said they are different, make your mind up
[11:58:33] <aventtini> on the 2.7
[11:59:01] <archivist> we are comparing 2.6 to 2.7
[11:59:04] <aventtini> 2.7 P=50 FF1=1
[11:59:06] <aventtini> yes
[11:59:32] <archivist> so set the 2.6 values
[11:59:43] <aventtini> no differance
[11:59:50] <aventtini> same result
[12:00:03] <aventtini> maybe its from mesa firmware
[12:00:17] <witnit> aventtini: you actually tried using the old config file?
[12:00:17] <archivist> same result tells us absolutely nothing, same as what
[12:00:41] <aventtini> it dont want move
[12:00:45] <aventtini> i give 1 mm
[12:00:56] <aventtini> it go 30mm 20mm
[12:01:11] <aventtini> it drifts it runs away
[12:01:31] <aventtini> its not a one way behaivior
[12:01:45] <aventtini> for example machine is se up on 3000mm/m
[12:02:01] <aventtini> i i give it 5mm to move
[12:02:14] <aventtini> it moves or slow or on a lag

[12:02:24] <aventtini> but encoders direction is check
[12:02:39] <aventtini> as i so on the video last night
[12:03:10] <aventtini> aaa another thing that i have seen also on the 2.7
[12:03:21] <aventtini> on the acceleration it has 750
[12:03:36] <aventtini> whats the 750 ? mm per minute
[12:03:56] -!- kalxas has quit [Ping timeout: 240 seconds]
[12:04:09] <aventtini> and max speed is set to 25
[12:04:18] <aventtini> usualy this is mm/s
[12:04:28] <jthornton> I have two machines running 2.7 with no issues what so ever so I suggest it is either a hardware problem (most likely) or a configuration problem
[12:04:48] <aventtini> i have 3 machine that dont work whit 2.7
[12:04:48] <archivist> three machines ?
[12:05:01] <archivist> I vote cinfig
[12:05:07] <archivist> config
[12:05:10] <witnit> I have a couple running 2.7 as well
[12:05:19] <jthornton> yes that points to configuration problems then
[12:05:33] <witnit> I second your vote on the configs
[12:05:43] <jthornton> maybe cinfig too
[12:05:49] <aventtini> i think maybe config is in mm?
[12:05:52] <aventtini> mm/s
[12:05:53] -!- sumpfralle [sumpfralle!~lars@megumi.opennet-initiative.de] has joined #linuxcnc
[12:05:57] <aventtini> or mm/m?
[12:06:20] <aventtini> olso on the ferror min is 0.0005
[12:06:34] <aventtini> so why it has 4 after the .
[12:06:41] <aventtini> its in inch ?
[12:06:45] <aventtini> machine is set in mm
[12:07:13] <aventtini> the nasty part is that we have 3 machine identical
[12:07:22] <aventtini> mikron wf21 wf51 wf72
[12:07:34] <aventtini> same motors diffrent neutons
[12:07:41] -!- Valen has quit [Remote host closed the connection]
[12:07:48] <jthornton> the same but different
[12:07:58] <aventtini> a little
[12:08:02] <aventtini> on the HP
[12:08:29] <witnit> Im still convinced that hitting the + jog button and seeing the machine go to -20mm is probably something you should solve before jumping to any conclusions.
[12:08:48] <aventtini> i did solve that in the morning
[12:09:36] <aventtini> you ware right
[12:09:39] <aventtini> on taht one
[12:09:42] <aventtini> that one
[12:10:43] <witnit> What did you do to correct it?
[12:10:55] <aventtini> the encoder diection
[12:10:59] <aventtini> direction
[12:11:17] <aventtini> i dont know on this video
[12:11:25] <aventtini> that i have posted but i have change that
[12:12:58] <aventtini> machines has a drive belt and the motor is rotated in diffrent direction
[12:13:02] <aventtini> on the table
[12:13:45] <archivist> I cannot see a logical thought process to diagnose problems
[12:14:07] <aventtini> on the 2.6 it dos not give any folow errors
[12:14:15] <archivist> use 2.6
[12:14:18] <aventtini> and its se up on 1 mm
[12:14:24] <aventtini> yes i will use it but
[12:14:32] <aventtini> problem is the arc blending
[12:14:49] <witnit> which axis is this?
[12:14:57] <aventtini> XY
[12:15:16] <witnit> both are broken?
[12:15:16] <aventtini> only Z is giving because i did not tune the acceleration
[12:15:45] <aventtini> no they work good XY
[12:15:53] <aventtini> whit no tuning done
[12:16:36] <aventtini> olso on the 2.7 i did put the P to 10000 and did not get any oscialtions on the motor
[12:16:46] <witnit> you said "it doesnt want to move" which axis is not moving?
[12:17:31] <aventtini> on 2.7 all of them
[12:17:55] <aventtini> on 2.6 all of them work perfect
[12:18:00] <witnit> according to your pictures of pncconf your max output = 0
[12:18:05] <aventtini> ye
[12:18:07] <aventtini> yes
[12:18:13] <aventtini> and i did put 10
[12:18:21] <aventtini> as the 2.6
[12:18:24] <aventtini> no diff
[12:18:30] <aventtini> same resault
[12:18:51] <archivist> I think you are not being methodical
[12:19:21] <aventtini> maybe
[12:19:31] <aventtini> i dont know i tryied all the ways
[12:19:45] <archivist> I dont think you have tried all ways
[12:20:01] <aventtini> maybe when PNconf is done whit 0 on the max out
[12:20:15] <archivist> using the old 2.6 config is step one
[12:20:28] <witnit> aventtini: when you copied 2.6 config to your 2.7 machine what happened?
[12:20:29] <aventtini> and you put on calibration or manualy it dont want to read
[12:20:31] <aventtini> that
[12:22:36] <aventtini> no impruvment same result
[12:22:45] <aventtini> let me do like tis
[12:22:48] <aventtini> this
[12:22:54] <aventtini> i tune the machine on 2.6
[12:23:00] <aventtini> then
[12:23:10] <aventtini> make a fresh instal on the 2.7
[12:23:18] <aventtini> whit same settings
[12:23:31] <aventtini> and i will post some pics
[12:23:38] <aventtini> on the setups and file
[12:24:00] <archivist> we dont want pics
[12:24:21] <archivist> fresh install wont help much at all
[12:24:23] <witnit> why not just bring us the config files like every other person does ever instead pictures which nobody ever does?
[12:24:42] <aventtini> i forget to get the usb drive :*(
[12:24:47] <aventtini> im at home
[12:24:51] <aventtini> files are not a problem
[12:27:05] <aventtini> i suspect machine is in inch
[12:27:48] <aventtini> did some instal a metric machine
[12:27:49] <aventtini> ?
[12:28:08] <aventtini> imposbile to have a default 0.0005
[12:28:16] <aventtini> on the min-fferror
[12:28:56] <aventtini> it has 1 as default on a metric machine
[12:29:48] <witnit> i just dont see how any of this is possible when you copied your ini and hal file over like you said, since such variable cannot change with copy/paste
[12:31:29] <aventtini> also on the maximum aceleration when you onpen the ini is 750mm/s
[12:31:36] <aventtini> this is incorect
[12:38:41] <aventtini> ok lets close the problem on monday i caome whit the files

[14:33:45] <jthornton> yea, the only mb's I could find were a bit pricey

[14:34:43] <jthornton> I was just nosing around on newegg and saw them
[14:35:48] <_methods> you need to select a mobo or msata card very carefully if you want full speed

[14:36:17] <jthornton> I've given up on that idea rather quick :)
[14:36:33] <_methods> yeah it's a rather convoluted thing right now
[14:37:27] <skunkworks> it just seems like a neat idea until you try to impliment it.
[14:38:00] <_methods> well they are neat you just have to be careful selecting the drive and the bus
[14:38:19] <_methods> but only if you're worried about maximum throughput

[14:43:20] <_methods> haha yeah i'm part of the problem
[14:43:52] <_methods> wicki: i would just use a plasma post processor
[14:44:05] <_methods> change torch on with knife down
[14:44:10] <_methods> torch off with knife up
[14:44:45] <_methods> dxftogcode
[14:44:49] <_methods> or whatever
[14:44:59] -!- mikegg has quit [Quit: Leaving]
[14:45:09] <CaptHindsight> or just swap a plasma cutter for the knife and watch that vinyl melt like buddah
[14:45:15] <_methods> hahah
[14:45:22] <_methods> and your machine catch on fire
[14:45:37] <CaptHindsight> be sure to put it up on youtube
[14:45:43] <_methods> ^^
[14:46:11] <wicki> hmmm... but this code does not turn the knife into the cutting-direction ?
[14:46:25] <CaptHindsight> there should be a channel for fun swaps like that
[14:46:38] <_methods> oh it's not a drag knife
[14:47:23] <_methods> i don't know of any post processors for an "axis" controlled knife
[14:47:24] <wicki> no - I want to turn the knife by a stepper-motor
[14:48:03] <_methods> yeah that's something you'll have to write yourself or get lucky finding someone that has done something similar
[14:48:49] <CaptHindsight> https://www.youtube.com/watch?v=yU_rFrEpGe0 Vinyl cutting on cnc plasma table
[14:48:59] <_methods> it would just be a matter of making the knife the A axis
[14:49:17] <CaptHindsight> unfortunately it looks like the plasma cutter was replaced by a knife
[14:49:23] <_methods> but getting a post process that kicks out a angle for the knife might be a bit more complicated

[18:00:21] <Magnifikus> need something to keep chips away from the screws ^^

[18:02:09] <Loetmichel2> and cant take much load there, either
[18:02:26] <Loetmichel2> so IF at all its only capable of milling close to the center of the table

[18:02:48] <Magnifikus> no heavy duty
[18:02:55] <Magnifikus> eh pcb
[18:03:09] <Loetmichel2> i would take a more "cartesian" approach for milling forces

[20:32:24] <Erant> Some flat bar and square bar it is, I guess.

[21:31:40] <XXCoder> I don't think it depends that much on cpu
[21:35:44] <malcom2073> MrSunshine: A lower jitter results in faster possible step rates
[21:36:10] <XXCoder> isnt one of better video card help on less jitter?
[21:38:11] <malcom2073> I've heard that somewhere, that video cards rather than onboard video helps
[21:41:02] <malcom2073> Anyone know if any of the cheap chinese drivers other than leadshines have anti-resonance?
[21:45:18] <XXCoder> probably not?

[22:33:04] <malcom2073> Sync: Nah

[22:33:14] <Sync> still
[22:33:14] <malcom2073> the big one that I removed servos from works great :-D
[22:33:29] <malcom2073> I do know though, it's a 3d printer, it would be much faster with servos
[22:33:58] <malcom2073> Well... in theory
[22:34:11] <malcom2073> I don't print at max speed anyway, but I get resonance at around 20-30mm/sec, which is where I usually print
[22:35:02] <Sync> it most probably would be faster

[22:41:50] <zeeshan> sync can you read german? :D
[22:43:07] <malcom2073> My acceleration is limited to about 2000mm/sec^2, any faster and I get flex when accelerating/decelerating, it's not a jerk issue (Can you even adjust that? I thought the new TP used constant jerk s-curve velocity profiles?)
[22:44:20] -!- likevinyl [likevinyl!~freebeer@unaffiliated/likevinyl] has joined #linuxcnc
[22:45:00] <malcom2073> Anyway, speed isn't the issue, midband resonance is :P

[22:45:58] <malcom2073> But that particular machine isn't worth sinking a grand into the motion control system

[23:42:41] <_methods> or it will twist up
[23:43:21] <_methods> an you usually need radii in the corners of the square
