06:01 PM _unreal_: quick someone get the smelling silicon (salts)
06:10 PM Bear100: CaptHindsight[m] thanks for your help.
06:10 PM _unreal_: Something I'll need a hand with "when" I get to it. I have never messed with it. but I have one of those threading bits for a cnc mill.
06:10 PM _unreal_: some of the holes will be 1/4-20
06:10 PM Tom_L: _unreal_, single point thread?
06:10 PM _unreal_: 6 1/4-20's will be more then enough per X ARM
06:10 PM _unreal_: not sure what that means
06:10 PM XXCoder: single start, meaning there is only one thread
06:11 PM XXCoder: tom funny because I designed threads in cad for first time
06:12 PM XXCoder: worked perfectly first time
06:12 PM _unreal_: then I'll have blocks at the ether end of the Y arms so I can adjust the pitch of the XZ when aligning/traming the machine
06:12 PM Tom_L: _unreal_, that one may not be that useful for you
06:12 PM _unreal_: dont know..
06:12 PM Tom_L: you need the tool diameter and yours will likely be different than that chart
06:13 PM _unreal_: added it to my references
06:13 PM Tom_L: having the major/root diameters is fairly contant though
06:14 PM _unreal_: My plan is to make a simple pitch/height adjustment for the Y arms to TUNE x. ONCE I'm happy with it. I'll have 2 more holes per Y arm. That will be already drilled in the angle aluminum. When everything is ready and fixed and bolted tight. the final "locking" holes will be drilled and tapped
06:14 PM _unreal_: by hand
06:15 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/threads/thread_classes_of_fit.pdf
06:15 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/threads/Thread-Calculations.pdf
06:16 PM _unreal_: any more and my brain is going to be full ;)
06:16 PM Tom_L: well then there _is_ a spreadsheet there too
06:17 PM _unreal_: heh
06:18 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/threading/charts/
06:18 PM Tom_L: there's a few more too
06:19 PM * roycroft is back to dealing with cad, and design tables
06:19 PM roycroft: i have a cunning plan to fix my problem
06:20 PM roycroft: the problem being if a dimension name is either missing or on a different sketch it won't be seen if i share the same table amongst multiple drawings
06:21 PM roycroft: but if i make a table for each drawing, with the drawing-specific info in it, i may be able to make the table values links to an external spreadsheet
06:24 PM roycroft: oh, this is a lot easier
06:24 PM roycroft: i don't need to use excel or design tables at all
06:25 PM roycroft: i can save global variables in a text file and link that to multiple drawings
06:25 PM roycroft: which presents a different set of problems, but they are easier to deal with
06:25 PM _unreal_: hence I like designspark and fusion360
06:26 PM roycroft: i'm certain this is not a sw-specific problem
06:27 PM _unreal_: UGH... I need to find some plate aluminum 3/8ths
06:28 PM roycroft: fusion360 is unacceptable to me due to the licensing and calling home requirements
06:28 PM _unreal_: normally that stuff just jumps out at me all the time. as of lately not so much
06:28 PM roycroft: and i remember looking at designspark a while back and did not see any compelling reason to change from what i already have and know
06:28 PM _unreal_: designspark requires a once a month call home
06:28 PM roycroft: ok, so it's unacceptable too
06:31 PM roycroft: anyway, i just bought this verison of sw, and don't want to invest any more money in 3d modeling software for a while
06:31 PM roycroft: the possible exception being one of the vectric products when i get my cnc router built
06:38 PM -!- #linuxcnc mode set to +v by ChanServ
06:38 PM -!- #linuxcnc mode set to +v by ChanServ
06:38 PM Tom_L: roycroft, i ended up using a text file on mine
06:38 PM roycroft: that seems the way to do it most easily
06:38 PM roycroft: the drawback being that i cannot keep a table of configurations in it
06:38 PM roycroft: i.e. it's a flat file
06:38 PM roycroft: so whenever i want to change something i have to edit the text file
06:38 PM roycroft: but for what i'm doing right now that is acceptable
06:39 PM roycroft: wow
06:40 PM roycroft: i just opened a copy of my cnc router assembly - the full assembly
06:40 PM Bear100: Now the wait for it to arrive from China begins. I wonder if the zero covid lockdowns there will slow it down.
06:40 PM roycroft: sw told me the last time i opened it it took a minute and 38 seconds
06:40 PM roycroft: this time it opened in 12 seconds
06:40 PM XXCoder: bear yeah good question. I ordered a lot of bearing balls and its open question how long ill wait
06:40 PM Tom_L: so you spent the other 26 telling us
06:40 PM Tom_L: :)
06:40 PM roycroft: not 38 seconds
06:40 PM roycroft: a minute 38 seconds
06:41 PM Tom_L: ahh
06:41 PM Tom_L: even better
06:41 PM roycroft: and i don't even have the new gpu yet
06:41 PM roycroft: the only difference is the new display
06:41 PM roycroft: which i still don't understand
06:41 PM roycroft: and windows does not even know what the display is
06:41 PM Tom_L: so most of the time it will still sit counting wait states
06:41 PM roycroft: it's calling it generic
06:42 PM _unreal_: I think china is trying "POPULATION" control currently
06:51 PM roycroft: i think it's probably best if you not elaborate on that here
06:51 PM Bear100: _unreal_ a 3 axis CNC router. It looks like <http://imgur.com/3aUYZ>.
06:51 PM * _unreal_ rolles eyes
06:51 PM _unreal_: Bear100, what is the max step rate your looking for?
06:51 PM XXCoder: that looks virtually exactly same as my cnc router
06:51 PM Tom_L: ooo that looks just like windows!
06:51 PM _unreal_: Bear100, I think your table is sagging a bit
06:51 PM XXCoder: except mine has shorter steppers
06:51 PM Tom_L: how quaint
06:51 PM Tom_L: XXCoder, space savers
06:51 PM XXCoder: really need to make box for my cnc electrics
06:51 PM XXCoder: no room however
06:51 PM Bear100: That is not my setup it is just a picture that looks like the CNC machine I have.
06:51 PM roycroft: the controller box for that router is the same enclosure that i just got for my kiln temperature controller
06:51 PM _unreal_: Bear100, did that cnc come with a motion control card?
06:51 PM Bear100: I do not run windows systems.
06:51 PM _unreal_: or are you craping what it came with and switching to the par-port card to drive the stepper motor controllers
06:52 PM _unreal_: if you have any ratios in there 2:1 etc.. or more. it dbls your step rate
06:53 PM _unreal_: and if you add micro stepping on top of that... you can quickly starve the machine
06:53 PM _unreal_: and this only applies really to your rapids
06:55 PM _unreal_: so.... what is the machines setup? lead screw type/pitch, stepper degree per step, (micro stepping if desired), and max rapids feed rate desired.
06:56 PM CaptHindsight[m]: what is a good use for an old trackball mouse?
06:56 PM _unreal_: CaptHindsight[m], I use one for my cnc
06:56 PM Bear100: _unreal_ okay thanks for pointing that out.
06:57 PM Bear100: _unreal_ it came with a USB to parallel port adapter. That did not work so I am trying asecond parallel port card.
06:57 PM _unreal_: which USB to parallel?
06:57 PM _unreal_: which adapter
06:59 PM _unreal_: IT MAY not be a "" PARALLEL PORT "" but rather a tuned "usb emu par port card" tuned for special cnc software.
06:59 PM _unreal_: what software if you know? came with the machine and that included usb/par controller?
07:00 PM _unreal_: chances are that adapter is not a "real" par port.
07:01 PM _unreal_: Bear100, ?
07:01 PM Bear100: CaptHindsight[m] "let us know when it shows up" will do.
07:01 PM CaptHindsight[m]: _unreal_: his thing-a-ma-bob uses some winders app to ken-trol them here moters
07:01 PM _unreal_: CaptHindsight[m], likely
07:02 PM CaptHindsight[m]: his thing-a-ma-bob has a bilt in BOB and stepper drivers
07:02 PM CaptHindsight[m]: so he-a reckinin to use LCNC with a LPT card to kentrol his thing-a-ma-bob
07:03 PM CaptHindsight[m]: since his thing-a-ma-bob has an LPT port
07:03 PM Bear100: _unreal_ the manual for the machine documented using it with mach3.
07:03 PM _unreal_: Bear100, its ether a MACH3 usb controller, a USB-CNC controller, or less likely a planetcnc controller. IF its a planet cnc controller its a really good adapter.
07:03 PM _unreal_: :p
07:04 PM _unreal_: 50/50 real mach3 usb controllers are like $200
07:04 PM CaptHindsight[m]: it don'ts be the planetcnc controller, it bees another brand
07:05 PM Bear100: _unreal_ these are technical terms "lead screw type/pitch, stepper degree per step, (micro stepping if desired)" I still have to learn.
07:05 PM _unreal_: Bear100, is this your first cnc?
07:06 PM Bear100: _unreal_ yes this is the first time i have tried to set up a CNC machine.
07:06 PM _unreal_: Bear100, and yes those are terms. First you need to know what the steppers are setup as
07:06 PM _unreal_: and if they are steppers or servos. servos have encoders. steppers do not
07:07 PM Bear100: _unreal_ I think they are steppers.
07:07 PM _unreal_: you need to know what degree the steppers are per step. Those are "whole" steps meaning the total number of whole steps or PIE slices that it takes to make a full circle
07:07 PM _unreal_: the steppers prob have 4 wires comming off them. if so they are bipolar steppers
07:07 PM _unreal_: fast powerful
07:08 PM _unreal_: its prob 1.8
07:08 PM _unreal_: 1.8 degree is 200 steps per rotation whole steps
07:08 PM _unreal_: do you have a book or CD that came with the cnc machine?
07:09 PM _unreal_: it should have info on the "values" you would need to ender into MACH3 to set it up
07:09 PM Bear100: I have to go away from the computer the workshop is closing. Thanks for all the help.
07:09 PM _unreal_: Bear100, remember, a cnc machine is nothing more then a coordinates machine.
07:09 PM _unreal_: fine leave be that way ;)
07:10 PM _unreal_: I would get that info if there still there.
07:10 PM _unreal_: take it home so you can research it
07:26 PM XXCoder: Tom_L: honestlyu those steppers I have is too weak
07:26 PM XXCoder: need better ones later
07:30 PM roguish[m]: there is no substitute for raw horsepower........
07:31 PM roguish[m]: ok, ttfn
07:32 PM Lcvette[m]: Is there still logs from June 2018 that are accessible?
07:34 PM Tom_L: Lcvette[m], http://tom-itx.no-ip.biz:81/~tom-itx/irc/logs/%23linuxcnc/2018-06-01.html
07:34 PM Tom_L: starting there
07:40 PM synfinatic_ is now known as synfinatic
07:49 PM CaptHindsight[m]: IchGucks was still around then
07:55 PM XXCoder: yeah. hes odd but nice guy
08:07 PM _unreal_: would be interesting if there was some nice way of using these systems :/
08:07 PM _unreal_: BCM7335QKFSBA1G
08:07 PM _unreal_: got a bunch of SAT recivers from work the other day.
08:08 PM _unreal_: the "computer" is a single board
08:09 PM _unreal_: with a 2x40 header
08:09 PM _unreal_: that is I/O and power
08:09 PM _unreal_: I got all of these recivers because they have hard drives in them
08:09 PM _unreal_: all 500gig drives :) got 14
