Foundry

Amy Weinstein:

TinkerMill has a foundry! It can use it to cast aluminum using a sand cast mold system. In the near future, it will be
able to used to cast bronze using an investment casting system.

Early next spring, 2019, the Foundry will be moving to a larger location in the back bay, on the south side of the welding area.

Over the winter 2018-2019, we will be holding a few planning meetings to design the new foundry area. Please contact us
through the foundry slack channel if you are interested in contributing to the design of the new foundry.

Basic foundry certification classes are offered once per month. To be fully certified, the certification class and
four independent pours are required. Often these can happen during the certification class. If not, there are always pour times set up
at the end of every certification class for this purpose. It is our intention to also begin to offer mold-making classes.

To use the foundry independently, two people present. Both the person pouring and the person
who is the safety backup person must have completed the safety certification course.

Presently there is a charge of $5.00 per pour to cover the cost of the gas. This may change with time as we have more
time to assess this. We have had a pile of scrap aluminum tubing, bar, and previously cast parts that we make into
ingots for classes and practice pours. We cannot supply this aluminum to you for your projects, however. There are
a few places where you can purchase scrap aluminum. This one is known and recommended to the foundry shop,
Alreco, 11299 Brighton Rd., Henderson, CO 80640, 303.287.7210. I don't find much web presence for them, though
they are known to have great recycled aluminum.

Laser Cutter

2017-02-22T04:06:12Z

Amy Weinstein: /* With Adobe Illustrator */

==Overview==
====== Specifications ======
'''Laser Model:''' Rabbit Laser QX-80-1290 80W 
'''Working area:''' 47.2 x 35.4 inches (1200 x 900 mm)
 

===== Parts of the Laser =====
'''X/Y carriage''' - Moves the laser head along the X and Y planes (left to right, toward and away.) 
'''Honeycomb table''' - disperses any reflected laser energy as well as positioning the engraving material within the proper distance from the laser head. 
'''Z axis Bed of Laser''' - Z axis Bed of Laser - The bed of the laser moves up and down to focus the laser. It can be lowered 10 inches under the laser focal lens. 
'''Laser Tube Water Jacket Chiller''' - A pump moves chilled, distilled water through a glass tube around the laser, cooling it. 
'''Compressed Air in''' - Air Assist is compressed air that blows onto the cutting point of the laser. It blows away smoke that would otherwise deposit on the mirrors 
 

==Safety==
=== Machine Safety ===
*'''Only use materials on the approved list! If your material is not on the list you must get approved before attempting to cut or engrave it!'''

*'''Do not exceed the recommended power settings more than 10 units. If the laser is not cutting at those settings, it needs maintenance. Please let someone know!'''

*'''Do not set the power setting above 85%. This extends the life of the laser tube considerably.'''

*Keep the area around the machine clean and free of unnecessary clutter, combustible materials, explosives, or volatile solvents such as acetone, alcohol, or gasoline.

The smoke generated from cutting materials deposit particles of residue on the lenses and mirrors of the laser. For the laser to work at its full potential proper maintenance is necessary. This is done by trained Tinkermill members so you don’t have to.

The machine is regularly checked and maintained but if you notice a loss in power or performance you can help by alerting a qualified TinkerMill member. If the laser does not seem to be cutting at its full potential please alert a member who has been trained in laser maintenance. If none are available please submit an email to '''info@tinkermill.com''' with a description of what you observed.
Do not attempt to clean the optics or service the machine without training!

Keep all the lids closed while the machine is in use, including those on the sides of the machine. 
 

=== Fire Safety ===
Laser cutting and engraving systems represent a significant fire hazard. 
The materials on the approved list most likely to flare up are paper based products such as cardboard. The most common cause of flare-ups is cutting too slowly. 
Keep a properly maintained and inspected fire extinguisher on hand.
 

== Material Selection ==
Our laser cutter is capable of cutting and engraving a wide range of materials. To help ensure that the laser stays in a working condition we ask that you only using materials on the approved material list. If you would like to use a material not found on the list (and it isn't on the do-not-cut list) please contact a shop captain and be prepared to provide a sample of your material.

You can help by testing your material according to the “IDENTIFICATION OF POLYMERS” booklet accompanying the laser cutter:
http://www.chymist.com/Polymer%20Identification.pdf
http://makezine.com/2011/09/22/identifying-unknown-plastics/

'''Do not cut any material that contains chloride as it is corrosive to both the machine and your body! These include PVC and vinyl.'''

==Usage==
=== Preparing Vector Files for Cutting and Engraving ===
* The laser cutter software uses DXF (Drawing Exchange Format) as its vector format
* DXF files should be saved in R14 version
* The laser cutter software expects metric measurements. Export at an Artwork Scale of 1 unit = 1mm
* Adobe Illustrator and Inkscape can convert vector file types to the DXF
* DXFs created with CAD software, such as Autocad, often has double lines or other undesirable artifacts from the conversion process. You should always open these files in vector drawing software and clean up any of these erroneous paths
* Make note of your documents size (in millimeters) as this will be useful later if resizing is needed in the LaserCut software
* Closed paths that are put on an Engrave layer in the RabbitLaser software will appear as solid areas of engraving.

==== With Adobe Illustrator ====
* Change the document's units to metric (Edit > Preferences > Units > General)
* All paths should have zero fill. Filled shapes will produce a "Hatch" error in the RabbitLaser software.
* When saving, uncheck the "Compression" checkbox that comes up in the second "Save" screen

==== With Inkscape ====
[[Preparing Files With Inkscape|Preparing files for LaserCut 5.3 in Inkscape]]

Both Inkscape 0.48 and 0.91 should be installed on the workstation. A few tips:
* Inkscape 0.91 has a bug that prevents it from saving circles and ellipses to .dxf format properly. You may need to use another tool (such as 0.48), or recreate them in the LaserCut software. This is expected to be fixed in version 0.92. See here: https://bugs.launchpad.net/inkscape/+bug/1489320
* If you are having trouble with exporting a closed shape, check to ensure that there is no "fill". Some users have reported this causing them issues in the past.
* Combining all vectors into a single layer before export may yield better results.

=== Preparing Raster Images for Engraving ===
The PhotoGrav software can be used to convert raster images into a format compatable with the RabbitLaser software. This is installed on the computer and can be found locked to the task bar (the sun icon.) 
 

=== Operating the Laser ===
# Turn the laser on with the key. Check to ensure that the Chiller, Air Assist Pump, and Ventilation Fan have all turned on.
# Scan your badge in the [[TinkerAccess]] kiosk on the top-right of the laser. It will activate the laser tube for a certain amount of time. For large projects, make sure to re-scan your badge before time runs out.
# Press the “XY-0” button to prevent the laser head from leaving the workable space.
# Start the LaserCut software.
# Click “File>Import” to navigate to and select your file.
# Select paths and assign colors to those that will have separate power and speed settings.
# Set the power and speed settings for each layer (color). Please reference the advice power and speed settings sheet that is near the computer.
# Layers will be cut/engraved in order from top to bottom. They can be arranged by pressing the "Up" and "Down" buttons underneath the Layers pallet
# Check the size of your artwork by selecting everything and pressing Ctrl+G. This will show you the selections size (in millimeters) and allows for its adjustment.
# Although not required, it is wise to save the file at this point to the computer or your thumbdrive. This will save the file in a .MOL format that will retain your layers as well as speed and power settings.
# Ensure that the origin, or starting point, of your artwork is set to the upper left corner by clicking on "Laser" > "Set laser origin" and selecting "LEFT-TOP."
## [[File:laser_origin_1.png|200px|Setting laser origin in Rabbit Laser software.]]
## [[File:laser_origin_2.png|200px|Setting laser origin in Rabbit Laser software.]]
# The screen on the laser cutter should now display the name of your file
# Place your material onto the laser cutter bed.
# Use the laser cutter’s up/down, left/right keys to move the head of the laser over your material. If the laser head doesn’t move when you press the buttons try hitting the “ESC” and try again.
# Press the “TEST” button. The laser head will travel in a rectangular pattern that represents the boundaries of your file. It is important that you know your origin point before testing or the head of the laser may ignore its limit switches and slam into the side of the machine.
# Press the “Z-0” button to automatically focus the laser. The bed will rise until a limit switch immediately left of the laser head is activated, it will then move back down to the proper focal distance.
# You are ready to cut/engrave! Press the “START” key to start the laser.
# Remove your material as well as any left over pieces. Don’t worry about scrap that falls through the the honeycomb, that gets cleaned out during maintenance. Do, however, remove any scrap that sits on or above the honeycomb that could obstruct material placed into the machine later. The vacuum cleaner next to the laser cutter works great for sucking up loose bits!
# Donate money for the laser cutter based on the suggested rate and the elapsed time it took to run, according to the time displayed on the laser cutter.

== Cleaning and Maintenance ==
Please refer to http://www.rabbitlaserusa.com/Manuals/LaserMaintenanceSchedule.pdf for maintenance instructions. 

Due to the delicate nature of the laser cutter, maintenance is to only be performed by trained members. Please do not attempt to clean or repair the machine without this one-on-one training and specific authorization. If you believe that the laser needs cleaning or other maintenance please send a message to [mailto:info@tinkermill.org info@tinkermill.org].

==== Lens Damage Examples ====
[[File:lens_damage_examples.png|Lens Damage Examples]]

==== Focal Length Sensor Plunger ====
It is necessary to periodically clean the tip of the focal length sensor plunger. Because this plunger is used to set the focal distance of the laser, a build up of debris will cause this distance to be off enough to affect the quality of cuts and etchings.

Resource Scheduling

2017-01-16T20:27:58Z

Amy Weinstein: /* Use the Calendar Links */

==Resource Scheduling==
Many of the resources at TinkerMill can be scheduled for use by TinkerMill members. All of the scheduling is done through Google calendars and is visible by TinkerMill members only. The calendar allows members to reserve time on equipment or rooms.

==Scheduling guidelines==
:*Members should try to schedule their time on the machine as early in advance as possible.
:*If a time slot is reserved by a member, it has priority over any other drop in users, even if the previous user is still using a machine.
:*If a member who reserved a machine in advance is more than 15 minutes late to their session, they forfeit their priority.
:*Members should limit their scheduled sessions to four hour blocks, with no more than eight hours scheduled in a single day.
:*Any unscheduled time is considered drop in hours where anyone can drop in and use the equipment at their convenience.

==How to View the Resource Calendars==
You may go to [http://calendar.tinkermill.org TinkerMill Calendar] and view any of the available calendars or chose from the links below for specific calendars.

==How to Add a Resource Calendar to your TinkerMill Calendar==
Being able to view a resource calendar on your own calendar can be a useful thing for knowing when equipment is reserved or not.

There are two ways to add a resource calendar to your personal calendar.
===Use the Resource Calendar Links===
This is an easy way to add single calendars at a time

#Click on the link for the Calendar that you would like (see above)
#In the bottom right hand corner of the frame, there is a small '''"+"''' button. By clicking this, you will add the calendar to your calendar.

===From your own TinkerMill Calendar===
More useful for adding multiple calendars at once

#In your TinkerMill Calendar in the left pane there is a list of '''"Other calendars"'''
#Click the drop down button near "Other calendars" and select '''"Browse Interesting Calendars"'''
#Select the '''"More"''' tab at the top of the list
#Click '''"Resources for tinkermill.org"''' from the list
#You will now get a list of all of the TinkerMill resouces. On the right hand side of each item, you may subscribe to each resource you would like to be shared in your TinkerMill Calendar.

==Reserving Resource Time==
From your personal TinkerMill calendar, you may reserve resource time the same way you would reserve a conference room.
#Create an event at the time that you would like to use the resource
#Click the event and select '''"Edit Event"'''
#On the left side of the screen, under '''"Add:"''' select '''"Rooms,etc."'''
#Select the resource you would like to reserve during that time. If the resource you would like to select does not show up, it means that it has already been reserved for that time and is not available.

==Resource Scheduling==
Many of the resources at TinkerMill can be scheduled for use by TinkerMill members. All of the scheduling is done through Google calendars and is visible by TinkerMill members only. The calendar allows members to reserve time on equipment or rooms.

==Scheduling guidelines==
:*Members should try to schedule their time on the machine as early in advance as possible.
:*If a time slot is reserved by a member, it has priority over any other drop in users, even if the previous user is still using a machine.
:*If a member who reserved a machine in advance is more than 15 minutes late to their session, they forfeit their priority.
:*Members should limit their scheduled sessions to four hour blocks, with no more than eight hours scheduled in a single day.
:*Any unscheduled time is considered drop in hours where anyone can drop in and use the equipment at their convenience.

==How to View the Resource Calendars==

==How to Add a Resource Calendar to your TinkerMill Calendar==
Being able to view a resource calendar on your own calendar can be a useful thing for knowing when equipment is reserved or not.

There are two ways to add a resource calendar to your personal calendar.
===Use the Calendar Links===
This is an easy way to add single calendars at a time

#Click on the link for the Calendar that you would like (see above)
#In the bottom right hand corner of the frame, there is a small '''"+"''' button. By clicking this, you will add the calendar to your calendar.

===From your own TinkerMill Calendar===
More useful for adding multiple calendars at once

#In your TinkerMill Calendar in the left pane there is a list of '''"Other calendars"'''
#Click the drop down button near "Other calendars" and select '''"Browse Interesting Calendars"'''
#Select the '''"More"''' tab at the top of the list
#Click '''"Resources for tinkermill.org"''' from the list
#You will now get a list of all of the TinkerMill resouces. On the right hand side of each item, you may subscribe to each resource you would like to be shared in your TinkerMill Calendar.
