[00:11:40] <gonzo_> eve peoples
[00:11:55] <gonzo_> anyone avail could give me some advice on mesaflash??
[00:12:38] <MrHindsight> just ask
[00:13:23] <Tom_itx> MrHindsight, it did leave off the '?' at the end
[00:13:55] <gonzo_> trying to test with a 7i90, the manual says use a --port param, but mesaflash complains that this is not a recognised option

[00:16:14] <gonzo_> trying without the port I get an error that 7I90EPP board not found
[00:16:44] <gonzo_> but without the port I'm nit sure how it knows where to look, parallel port of pic ??
[00:16:47] <gonzo_> PCI
[00:18:55] <MrHindsight> the Mesa PCI driver finds the other PCI Mesa cards, not sure if the 7i90 is special since it's new

[00:20:17] <MrHindsight> sorry confused that with another board

[00:20:40] <MrHindsight> gonzo_: are you using the LPT port to connect to it?
[00:20:58] <gonzo_> yes LPT
[00:21:20] <MrHindsight> you can find the LPT address by LSPCI-vv
[00:21:39] <gonzo_> I previously managed to write to the flash using the dos utils. Now booted in linux and want to varify that I still have comms
[00:22:19] <MrHindsight> sudo lspci -vv
[00:23:04] <MrHindsight> LPT on a PCI card or integrated in the mainboard?
[00:23:11] <gonzo_> integrated
[00:23:19] <gonzo_> what should I look gerp for
[00:23:22] <gonzo_> grep
[00:24:48] <gonzo_> but pretty sure it is at the default address, which from mem is the 0x378 as in the mesaflash docs example
[00:25:10] <MrHindsight> does your BIOS let you choose the port location?

[00:32:08] <gonzo_> the example says that without a cammond I should just get info
[00:32:47] <gonzo_> mesaflash --device 7I90epp says that no 7I90epp found
[00:32:54] <MrHindsight> did that work without a command?
[00:33:07] <gonzo_> mesaflash --device 7I90epp --port 0x378 says that --port is not a valid option
[00:34:27] <MrHindsight> If mesaflash is run with no command line arguments it will print usage information

[00:37:20] <MrHindsight> yes
[00:37:33] <MrHindsight> not a debug report

[16:44:28] <zeeshan> so im calculating the feed force required for a worst case scenario. one of the most energy consuming materials is 4340. power constant of 1.31 hp/(in^3/min) and hardness of 485 HB. using a maximum depth of cut of .125" and the recommended feedrate for a .002 ipr, im finding out my feed force is approximately 70lb
[16:44:47] <zeeshan> that means my bracket that attaches to the apron and the ball nut
[16:44:51] <zeeshan> will see this force
[16:45:03] <zeeshan> meaning it'll deflect 0.0008" at those parameters
[16:46:00] <zeeshan> since the bracket deflects by that much, wouldn't this show up as 'backlash'
[16:46:20] <zeeshan> but its a consistent back lash
[16:48:24] <MrHindsight> how do you know it will deflect by 0.008"?

[16:49:15] <MrHindsight> and how about when measured? vs simulated/calculated
[16:49:27] <zeeshan> MrHindsight: i did a cutting forces lab a while ago
[16:49:42] <zeeshan> i don't personally have a load cell
[16:49:44] <MrHindsight> great, have you measured it yet?
[16:49:54] <zeeshan> but the formula was within +/-8%
[16:49:58] <zeeshan> so it's accurate enough
[16:50:16] <pcw_home> Samco did that with spindle temperature comp
[16:50:26] <zeeshan> i'm wondering if that 0.0008" would show up as back lash or not
[16:50:26] <MrHindsight> you keep on assuming something that I am not
[16:50:27] <zeeshan> i mean
[16:52:23] <MrHindsight> maybe, maybe not. We simulate all the time as a ballpark then actually measure.
[16:52:24] -!- larryone has quit [Ping timeout: 240 seconds]
[16:52:50] <zeeshan> for example i'm confused about this. imagine a 2" diameter x 6" piece, i'm cutting 4340, at a depth of cut of 0.125" and 0.002 ipr, which requires feed force 70lb, length of cut is 2.0000" one pass. ---- this is a roughing pass.
[16:52:57] <zeeshan> if i command 2.000 to be cut
[16:53:12] <zeeshan> in reality it would only cut 1.9992 due to the deflection right?
[16:53:23] <zeeshan> and "flex of the lead screw bracket"
[16:53:31] -!- IchGuckLive [IchGuckLive!~chatzilla@95-89-97-70-dynip.superkabel.de] has joined #linuxcnc
[16:53:37] <IchGuckLive> hi all
[16:53:40] <IchGuckLive> B)
[16:53:54] <MrHindsight> possibly or somewhere in between or as a pattern near those limits
[16:54:05] <zeeshan> now lets say i go back to home
[16:54:07] <zeeshan> and do a second pass..
[16:54:22] <zeeshan> and command 2.0000" (finishing pass) which only requires 10 lb of force
[16:54:31] <zeeshan> and deflects only by 0.0001"
[16:54:52] <zeeshan> would it actually make the piece 1.9999"?
[16:55:07] <zeeshan> or would it be some weird number
[16:55:13] <zeeshan> because of the way the screw is flexing
[16:55:14] <MrHindsight> it might oscillate and vary by the type of and number of cutting faces
[16:55:32] <zeeshan> but the error will always be consistent through right?
[16:55:35] <zeeshan> within a specific range
[16:55:41] <zeeshan> it won't stack up right?
[16:55:47] <MrHindsight> it's probably not constant either, like a boat going over waves
[16:55:52] <zeeshan> ofcourse
[16:56:01] <zeeshan> this is to get a rough idea of what kind of error it is
[16:56:06] <zeeshan> i'm confused if it causes a stack up error
[16:56:22] <zeeshan> or an error within the rigidity bound of the bracket
[16:56:41] <MrHindsight> heh, welcome to modeling dynamic systems
[16:57:03] <zeeshan> MrHindsight: i'm not trying to get the exact numbers
[16:57:07] -!- somenewguy_shp has quit [Ping timeout: 252 seconds]
[16:57:10] <zeeshan> i'm just trying to figur eout the type of error :P
[16:58:07] <MrHindsight> if cutting depth changes the amount of force on the screw and bracket then it will probably bend less
[16:58:56] <MrHindsight> so in the one situation you might have 0.0008" and in the other 0.0001" deflection sure
[16:59:15] <MrHindsight> and if you change speeds some other amount of deflection for both
[16:59:32] <zeeshan> yes
[16:59:58] <zeeshan> so basically to hit my exact target
[17:00:06] <zeeshan> i need to just lower the cutting forces during the finishing pass
[17:00:09] -!- md-2 has quit [Quit: Leaving...]
[17:00:20] <zeeshan> and i can expect to hit my target pretty close
[17:00:32] <zeeshan> (this is a stepper system)
[17:00:40] <MrHindsight> and something non-linear if you get into any resonant modes
[17:01:35] <zeeshan> resonance is a whole different ball game :P
[17:01:46] <zeeshan> cutting forces oscillate like crazy.
[17:01:47] <zeeshan> :P
[17:01:51] <zeeshan> especially the tangential one
[17:02:01] <zeeshan> the formula i have assumes no resonance
[17:02:32] <zeeshan> if you start included resonance, you gotta solve it numerically cause its a long ass differential equation
[17:02:40] <zeeshan> based on the system
[17:02:46] <MrHindsight> lots of people like to start some exact expected number as a result, I usually approach it from chaos and try to limit or control all the variables
[17:03:08] <zeeshan> well cause i've never designed a bracket for this scenario before
[17:03:12] <zeeshan> so i need to get in the ball park :P
[17:03:29] <zeeshan> i need to know if 70lb will give me 10 thou of deflection of 1 thou or tenths
[17:03:52] <MrHindsight> things are always moving, twisting, changing temp, getting contaminated, oxidizing etc etc
[17:03:56] <zeeshan> ofcourse with resonace your typical 1 thou deflection can peak 10 thou
[17:04:01] <zeeshan> but you'd know something is really wrong!

[17:05:20] <zeeshan> this is what the bracket looks like

[17:05:41] <zeeshan> but according to simulations its not
[17:05:44] <MrHindsight> in a static situation wouldn't you get the 0.0008" deflection based on a 2" diameter x 6" piece, i'm cutting 4340, at a depth of cut of 0.125" and 0.002 ipr, which requires feed force 70lb, length of cut is 2.0000" one pass
[17:06:28] <zeeshan> you'd prolly get less i'd presume
[17:06:32] <MrHindsight> that force is based on the size and depth of cut
[17:07:19] <MrHindsight> are you questioning your formula or?
[17:07:31] <zeeshan> it just looks overly big to me.

[17:07:38] <zeeshan> but i've never really designed for 0.0001 " deflections before
[17:07:41] <MrHindsight> I'm not exactly sure since from my perspective you answered your own question
[17:07:45] <zeeshan> mostly i've designed for strength
[17:07:58] <zeeshan> MrHindsight: no you've helped me confirm some things.
[17:08:03] <zeeshan> cause i was kind of lost
[17:08:15] <zeeshan> as to what kind of error it'd cause
[17:08:31] <zeeshan> i was thinking it'd cause a stack up error like when you stack up 10 different gage blocks together

[18:26:46] <humble_sea_bass> #emacs -- not even once

[18:29:14] <_methods> even the mention of his name drags the room iq down like 200 pts

[19:32:23] <MrHindsight> why do most at the makerfairs/spaces have such resistance to actual science and learning?
[19:32:35] <malcom2073> Because most science and teaching people won't talk to them.
[19:32:54] <MrHindsight> the ones around here are all 20 somethings that act like know it alls
[19:33:10] <malcom2073> That's because the smart decent ones get driven out.

[22:28:44] <sabotender> I do not *quite* understand why they are so craptastic in that manner
[22:28:59] <sabotender> or maybe it is simply a linuxcnc limitation
[22:29:29] <sabotender> I have seen some machines in videos powered by notebooks/laptops, but they were running mach3 I think it is called
[22:29:41] <Connor> sabotender: Laptops have lots of stuff to make them more energy efficient for battery usage.. They use Interupts and stuff which can mess with RealTime OS
[22:30:19] <sabotender> ah I see, well that makes sense I suppose
[22:31:06] <sabotender> I had to disconnect my server because it was drawing too much power, with being on 24/7 and it was running up my energy bill
[22:31:13] <Connor> Most likely the ones you see running Mach3 are using a offboard controller, which handles parsing the Gcode and generating the pulses to the steppers... and feeding data back to mach3
[22:31:23] <Connor> where as linuxcnc *IS* the machine controller

[22:33:58] <sabotender> is it true that a simple cnc router can cut though thick (insert substrate here) but it would need many passes?
[22:35:56] <PetefromTn_> What Connor NOT COOL???!!! This guy is the COOLEST fellow on here in my view ;)
[22:37:49] <Connor> sabotender: depends.. the diameter of the end mill might play a role... if you use too long of a endmil you might end up flexing (and breaking) the endmil.. and also depends on chip evacuation..
[22:50:52] -!- jerryitt has quit [Quit: Connection closed for inactivity]
[22:51:55] <andypugh> How thick is thick?
[22:52:32] <andypugh> Eventually the length to diameter ratio of the cutter starts to cause problems.
[22:53:33] <sabotender> andypugh: oh im not sure. greater than an inch in depth?
[22:53:34] <andypugh> But I have cut 20mm deep with a 3mm cutter, and that was in steel.
[22:54:09] <andypugh> An inch is easy. You can do that with a 3mm cutter, in Aluminium, without too much trouble.
[22:54:21] <andypugh> A 6mm cutter would go deeper.
[22:54:41] <andypugh> I thought you were talking about 6” deep with a 1/2” cutter.

[22:57:25] <syyl--> Oo
[22:57:39] <andypugh> Have you looked at benchtop mills? They are likely to machine aluminium better than a router will.
[22:57:56] <andypugh> (Not BCN at that price, though).
[22:58:10] <andypugh> BCN? Where was I on the keyboard?

[23:00:53] <syyl--> if you take light cuts
[23:01:18] <andypugh> Actually, there is a guy on the forum doing OK cutting aluminium on a machine constructed entirely from wood.
[23:01:42] <andypugh> Well, not _entirely_ from wood. Wooden stappers hardly work at all :-)
