Lamont: /* Tooling */

Here's the beast: http://www.maxnc.com/maxnc_10_cl-b.htm

== IMPORTANT! ==

Improperly used, the mill can destroy itself, its tools, and parts of you. Please know what you are doing and don't be afraid to ask questions.

* RTFM! Know how to home each axis, and what tools to use, how to shut down, etc. http://www.linuxcnc.org/docview/html/

* Always check limits by manually running outside your mill area with the tool at a safe Z height.

* DO NOT UPGRADE THE UBUNTU 8.04 OR THE KERNEL ON THE HOST MACHINE!

* DO NOT MILL PRINTED CIRCUIT BOARDS WITH STEEL TOOLS! (Carbide only, see [[#Tooling | Tooling]] )

* USE EYE PROTECTION unless you like tweezering debris out of them

Right now, we need to be watching it all the time, and only run things near the middle of its ranges (so we have time to turn it off).

If it appears to be getting out of hand, the F1 key should toggle Emergency Stop in the software. This will power down the spindle and stop it where it is immediately.

If it REALLY IS getting out of hand, turn the power switch off (the one on the side of the control box). Note however that after doing this you'll probably need to restart the software because it will be out of sync with the controller (it gets out of sync).

== Software ==

We are using http://linuxcnc.org EMC2 and AXIS software to drive the mill. We had to hack the config files considerably and reverse-engineer the pinout. See here for documentation: http://www.linuxcnc.org/docview/html/

We have installed EMC2 and AXIS and some other software on the driver PC. This depends on a custom kernel and Ubuntu 8.04 -- PLEASE DON'T UPGRADE!

The EMC2/AXIS software takes GCode as motion control input files. More info here: http://www.linuxcnc.org/docview/html/
We have figured out several Gcode [[#Toolchains]] for your CNC enjoyment

===Local Installation===

To experiment with EMC2/Axis machine on your personal Ubuntu/Debian setup, you may not want to apt-get emc2 because that depends on a special rtai kernel and Ubuntu 8.04. Here's a way to apt-get the pure simulator: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?EMC2_Pure_Simulator

If you are badass, you can compile the code in simulation mode following the instructions here:
http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#Building_emc2_simulator

The resulting binary should run and give you a UI on your system. There's actually nothing machine-specific that you need at this point: your UI will look pretty much exactly what we have now. Select the "axis.ini" config file.

You should now just be able to:

*open one of the sample gcode files
*power the machine 'on' (unset emergency stop [red X], and set power [orange square] buttons)
*'home' the various axes (must home all axes, use radio buttons to select)
*'run' the gcode. (blue "play" triangle)

For most of the configurations there is a smaller window w/ an inverted cone representing the spindle (this is the default view). This will show the progress of your milling run. You can change the view and pan/zoom/tilt with the mouse.

For a sanity check, try simulating a run of the NB logo gcode from [[Identity]]

Then try gcode from the [[#Toolchains | toolchain ]] of your choice.

== Toolchains ==

Many tools exist for generating/converting to gcode. Here's a good list: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Cam

In particular, here's how you generate gcode from

text / truetype : http://www.timeguy.com/cradek/truetype

=== EagleCAD ===
Cadsoft [http://www.cadsoft.de/ EagleCAD ] http://www.pcbgcode.org/
This worked pretty well, but you need to add the command
s 0.5
to set the speed before the motor will turn on. I'm sure you can add this to the default header.

===[http://www.inkscape.org/ Inkscape ] ===

This is cool but only works for Inkscape 0.43: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?InkscapeHowto

For Inkscape 4.6, use this: http://bitbucket.org/jst/inkscape-gcode/
(Do "get source", put all files in /usr/share/inkscape/extensions/)

It's still a little buggy, arcs are not completed. Put the figure you want to export ABOVE the page boundary on the left. Use "save as EMC gcode (.nc)" and tick all the checkboxes.

You need to add/change the following lines:

Set the cut height to -0.01
#2=-0.0100 (Height to cut at)

Add commands to turn on the motor after the first line:

G00 Z#1
S 0.5 (set motor speed to 1/2)
M4 (turn spindle motor on)

And you are good to go.

== Tooling ==

Cutting fiberglass (PCB) will eventually destroy any kind of steel cutting tool. You need carbide tooling.
Available from suppliers: http://www.precisebits.com/applications/pcbtools.htm http://thinktink.com/ Note that carbide is too brittle for most metals and will just snap.

High Speed Stainless (HSS) tooling available here: http://littlemachineshop.com/

search for "small parts inc" on amazon.com. They have reasonable prices and reasonable shipping for endmills. (You can also search for endmills) I believe we have a 1/4" and 1/8" collet for the mill, so you're looking for tools with a 1/4" or 1/8" shank. I mostly bought HSS for cutting plastic, but I have some harder ones with exotic coatings for aluminum and brass. --lamont

== Parallel port DB-25 pinout ==

* One pinout from http://www.machsupport.com/forum/index.php?action=dlattach;topic=1319.0;attach=891)
* http://www.super-tech.com/root/drawings/gif/SuperCam_pinouts.gif "setptype = user1" (confusingly not labeled MAXNC10)

OK, got a definitive pinout, seem to conform to those above. [[User:Jtfoote|Jtfoote]] 23:11, 28 September 2009 (PDT)

Pin 1: Tool speed PWM, active low
Pin 2,3: A quad input
Pin 4,5: Y quad input
Pin 6,7: X quad input
Pin 8,9: Z quad input

Pin 10: 7420 quad nand output (motion complete ack?)
Pin 11: NC
Pin 12: X,Y,Z limit (or'ed active high when at limit)
Pin 13: spare digital (unused header labeled "probe")
Pin 14: Enable, active high
Pin 15: NC
Pin 16: input to 4x PICs: enable, active low (reset?)
Pin 17: Enable, active high
Pin 18: GND
Pin 19-25 - NC

== Misc other info ==

Manual:
http://engineering.purdue.edu/AAE/Academics/Courses/Raisbeck/images/resources/cnc/MAXNCmanual.pdf

This guy rebuilt his, has derogatory things to say: http://hans-w.com/cnc.htm

This other guy has some interesting upgrades. Especially notable is the new motor mount, and appropriate dxf http://www.timeguy.com/cradek/cnc/motor-mount

[[User:seph]] was hacking on one. Some notes from him are at http://www.directionless.org/tmp/maxnc/
There's a pinout, and an emc2 config. He also recommends thinking about eventually upgrading a lot of the components. Seph's work is what I (mikew) based the current functional HAL and INI files on.

Lamont:

Items marked with a "*" are things we'd like people to bring from
home. Please edit the item with your name and how many you can bring
so we know what's coming.

needed:
* mop handles with standard wooden threads for head attachments ( x5 ) *
* mild abrasive head for mop handles (ex: rough back of sponge) ( x5 ) *
* synthetic lambswool heads for sealant and finish ( x10 )
* mop head attachment for lambswool applicator ( x5 )
* drum sander ( x2 ?)
* many belts, 40 grit, 60 grit, 80 grit. Plus a line on where we can get more over the weekend if we run out
* powerful rented shopvac ( x2 )
* edge sanders, ( x2 )
* taped hacksaw blades for cleaning out between boards
* boxcutters, folding or otherwise for same
* make sure we've got enough extension cords to reach everywhere *
* your own kneepads *
* respirators, possibly for the sanding up putty phase *
* more trowels, ideally board width. ( x10 ) *
* fans to promote faster drying phases *
* mats to wipe feet ( x2 ) *
* big garbage cans ( x2 )*

drum sanders will be $95 per, edgers will be $35 per, shop vacs will
be $30 per, total of 364.80 with the 14% damage insurance.

I'll overbuy on sealant and finish and return what we don't use on monday

pre-friday:
* take trash to dump
* start moving everything to the rear window linoleum area
* need vehicle to make run to pacific flooring supply company to get rest of sealant and finish

friday:
* acquire all the crap from above, rent from hertz at 3pm
* move every single thing in the building to the linoleum area
* leave a space and tools for minor woodworking in case we have to make a wooden plug
* leave space near the sink for cleaning
* at 3pm, edging team starts working the edges of the space and around the columns with hand sanders, 40 grit. Also need boards cleaned and vacuumed in that edge area, how to time?
* at 3pm, start stripping floor with 40 grit, diagonal pattern, then with the boards
* as areas are sanded, scraper team of people scrapes out between boards. Someone behind them vacuums
* putty team starts puttying. Puttying most time intensive. Mark time on grid when putty is applied so we know roughly when to expect it to be dry. Use a light touch, work it into the cracks, and try and keep the boards themselves free of putty.
GOALS: have entire floor clean and work crews started.

saturday:
* dump run to drop off sawdust + crap?
* hand sander, cleaning and putty crews continue. Mark time when sections are putty'd so we know roughly when we can sand it
* once hand sander team finishes, they need to re-sand the same areas from the dry putty using 60, then maybe 80 grit.
* GOALS: have entire area sanded, cleaned and puttied, fans going overnight to dry out area.

sunday:
* drum sand any dry putty area with 60 grit, then 80 grit. Only need to go with the boards
* hand sander team does same thing
* vacuum/sweep area pre-sealing?
* teams of two lay down and mop out sealant. Hopefully finished before lunch. Mark place on map to allow for drying time staggering.
* 2-3 hours needed for drying
* teams of two lay down bottom finishing coat
* 2-3 hours drying
* teams abraid surface
* teams of 2 lay down bottom finishing coat
* we keep out of space for 24 hours to let the floor cure/set

monday:
* return hertz rented stuff by 9am
* nobody goes in the space all fucking monday

Floors

2009-08-19T00:48:57Z

Lamont:

I estimate we've worked on about 1/15th of the total surface, which should take 12 person hours, and $100 in consumable materials.

I estimate to do the entire floor would take 180 person/hours and cost no more than $2000. ($1,800 in materials and $200 in rentals)

Lessons learned:
* we applied putty at least 2x as much as needed. Should have mopped clean later
* rotary sander is a difficult beast, should have stuck with the drum sander
* these shop vacs suck balls. The rental one was the best.

labor accomplished:

* 2 person hours vacuuming/digging up cracks
* 2 person hours sanding/vacuuming (40 grit)
* 3 person hours filling with putty
* (24 hour delay)
* 2 person hours sanding/vacuuming (60 and 80 grit)

labor estimated:

* 1 person/hour applying sealant
* (2-3 hour delay)
* 0.5 person/hour applying bottom finish coat
* (2-3 hour delay)
* 0.5 person/hour abraiding with rough sponge
* 1 person/hour applying top finish coat

tools needed:

* drum sander (rental, $95 for the weekend)
* shopvac (rental, $30 for the weekend)
* sponge mop
* trowels

materials needed:

* putty $70 for a 3.5 gal, used $20 of it
* belts .5 $10 40 grit, same for 60 and 80

No Starch Books

Lamont: /* Add Your Book Order Here: */

=== No Starch Press ===
'''No Starch Press''' is a publisher of tech books in San Francisco. Bill Pollock, the owner of No Starch, he has been generous enough to donate one of every title that they publish. These books are all on the Noisebridge library shelves.

Anyone is free to read the books in the Noisebridge library at no charge. But you may also want one of the books for your own.
 
 
=== No Starch Press has also made a generous to help Noisebridge: ===

Anyone associated with Noisebridge can buy any No Starch Press title at 75% of the retail price (you don't have to be a member). 50% of the retail price will go to Noisebrige. This is a great way to get books you want, and help Noisebridge at the same time.

If you would like to take advantage of this, please add the title you would like and your name, below. At the end of each week we will send the order in to No Starch Press, and your book will be delivered to Noisebridge. It's that easy.

=Bulk Order Parts List=

==March==

dr_jesus will be handling the March digikey order; please add your parts to this list. (Use four tildes to sign.) The order will be placed on '''Tuesday, March 24'''. Paypal cabal@hackershells.com with your cash or give it to me directly, and I'll mark you as paid in the table. (It's is a Paypal verified address, in case the whole "hacker" thing squicks you. I'm using that address because the accounting software is already set up for it for another geek community.)

PLEASE MAKE SURE to put your wiki user ID or some other way of identifying you in the comment field when you make the payment. There's some software that looks for a mediawiki user ID in the paypal data. Thanks.
