==Narwhal Labs Laser Material and Settings Library==
A library of known materials and laser settings that have been tested to work at Narwhal Labs on a Thunder Laser Nova 35 100W CO2 Laser Cutter and Engraver. Settings are not guaranteed to work and should be considered a baseline. Please add to or update this page if you test a new known material. Please obey all safety protocols listed on our [[Laser Cutting_and_Engraving|main laser information page.]]

CNC Machining

=='''CNC Machining at Narwhal Labs'''==
==='''Our CNC Routers and Equipment'''===
''''''Narwhal Labs is equipped with an AvidCNC PRO2448 CNC router with a 2.2kW (3HP) spindle, a NEMA34 electronics package, proximity sensors, a corner finding touch plate, mach 4 control software, and a complement of tools and tooling courtesy of AvidCNC and Bits&Bits.
===AvidCNC Cycle Start Checklist===

# Locate the emergency stop
# Home all axis on the machine
# Confirm material dimensions
# Preview toolpaths/Run simulations
# Secure workholding
# Check router bit installation
# Verify work coordinate system (WCS) 
# Review Mach 4 & G-code
# Test the spindle
# Re-install dust shoe

===CNC Router Etiquette===

* CNC routers can be very loud and make unpleasant sounds. Check with others in the room before running
* Please work with staff if you need to do long (1+hr) operations on a CNC.
* CNC routers, even with dust collection, can throw dust and chips. Please be considerate of others that may be near by or that may be doing epoxy or finish work that is negatively affected by dust
* Use ample workholding and tabs in your programs. Flying parts can be dangerous to you and those around you
* Please inform staff of any broken tools/tooling or machine faults so we can keep things running for all members.

===Software===
Our CNC router operates on Mach 4 control software.

We also have a license of vCarve pro that is located and running on our main laptop for the CNC router. You can use the free trial version of vCarve Pro on your personal computer or a Narwhal Labs loaner laptop to do all design and CAM work, then use the CNC laptop on-site here to export your G-code. The free trial enables all features except G-code export and has no time restrictions.

While Narwhal Labs does not endorse any specific design software package, our staff has some experience with Autodesk Fusion 360. It is a full-featured CAD and CAM package that is free for personal and education use.

===Feeds and Speeds===
Feeds and speeds refers to the feed rate, spindle speed, and plunge depth of your CNC program for a specific bit. These get calculated into a "chipload" or "feed per tooth". Try and aim for a feed per tooth or chipload of around .005. '''''Main article:''''' [[feedsandspeeds|CNC Router Feeds and Speeds]]

Our printers are each connected to an OctoPrint server for easy management of gcode files and control from within Narwhal Labs. Please see a staff member or Mentor if you need help connecting and getting started.
===Shop Rules for 3D Printing===
Please collect your prints when they are completed. If you are not available and a printer is needed, staff or a shop mentor may remove your completed print to make the printer available. Narwhal Labs is not responsible for prints damaged during removal. Narwhal Labs will not restart failed prints for you. We recommend troubleshooting why it failed and changing settings before starting again. “Not Safe For Work” projects are not okay. Please don’t make us get more specific. Using 3D printers or other equipment to make functional firearms or firearm parts is not permitted. Please do not invite controversy or legal issues into our community. 

A selection of PLA is available for personal projects as part of your membership. We ask that you bring and use your own filament for larger projects and production runs. Label your filament spool so we know to remove it before another member uses the printer.
===Recommended software===
We recommend Cura for slicing. Other slicers such as Prusa Slic3r and Simplify 3D may work, but we may not be able to help as much with them. [https://ultimaker.com/software/ultimaker-cura Get the latest version of Cura here.]

For parametric modeling, we recommend Fusion 360. It is free for personal, education, and startup business use. [https://www.autodesk.com/products/fusion-360/overview Sign up for and download Fusion 360 here.] For organic and generative modeling, Blender is free and open source.

==Laser Cutting and Engraving at Narwhal Labs==
===About our tools:===
We have a Thunder Laser Nova 35 100W CO2 laser with a CW-5000 chiller, exhaust, and 2 stage air assist. It has an adjustable Z axis and autofocus. Lightburn has a camera connected and calibrated for image/material placement and tracing. We also have a RotoBoss roller rotary for engraving cups, water bottles, and more. This laser runs primarily on LightBurn for a software package, though RDWorks is available to use if you're more comfortable with it. A camera connected to lightburn makes aligning projects easier, and includes some tracing features. A laptop is always connected to the laser with necessary software available on it. Please use a flash drive for your files. Settings and files are not saved on the laptop. [https://drive.google.com/file/d/1vYkoADEw_bPgJnLvvr3ryFvZpQxK9tZI/view?usp=sharing The manual for the Nova 35 can be found here.]'' '' ''This laser and our software was generously provided to us by Thunder Laser USA. We appreciate if you can tag and mention them on social media when using it. It helps them know how much we appreciate their contribution to our space.''

==='''Laser Safety'''===

* Locate the emergency stop and type BC Halotron fire extinguisher
* Be sure chiller is on and exhaust duct is open
* Never leave a running laser unattended
* Do NOT ever defeat or bypass safety interlocks*
* NEVER cut/engrave PVC or other vinyl and unknown materials*
* Make sure laser is in focus to your material
* Preserve our tools! Run lower speeds at lower power when possible
* Clean up and close exhaust duct when finished
* If you don't know, ASK!
''*Special note about PVC:'' When PVC is cut or engraved, it emits deadly chlorine gas, which in addition to being extremely toxic in even small amounts will nearly instantly corrode the internals of the machine. PVC is also known under many other trade names such as Sintra. Even common craft adhesive vinyl such is Oracal 651 is PVC based. If you think a material could be PVC based, do not even consider cutting or engraving it on any laser cutter/engraver. Putting ANY materials that you do not know the makeup of in the machine is strictly prohibited. ''*Note about UV radiation:'' This laser emits highly concentrated UV light that can permanently damage vision and cause injury. While the lid and access panels are closed, the laser is safe to operate. Specialized UV laser radiation protective glasses are available if you want extra assurance. Defeating safety interlocks to run the laser with the lid open is strictly prohibited. Operating the laser with a pass-through panel open is permitted only with staff or mentor assistance. Operators must wear laser safety glasses if the pass-through is open.

===Operating Notes===
In our own testing, we found that it is better to "send" your job to the laser, open it on the LCD panel, and run it from the laser. Running the job directly from lightburn can result in some undesired results with the dual-stage air assist, and is not supported for the rotary engraver.

The laser head must be fully inserted prior to running autofocus. While autofocus on the machine works, please be prepared to hit the e-stop if you believe the laser head is about to crash into your workpiece. Crashes can result in time consuming re-alignment procedures needing to be performed. Make sure your workpiece is in line with the IR autofocus sensors. Manual focus by getting your workpiece close and manually adjusting the height of the laser lens using the supplied acrylic "puck" and tightening with the thumb screw is an easy and reliable way to focus the laser.

Laser tubes are a consumable and have a limited life. Tubes last on average around 3 years or 3000 hours. This time is severely shortened when running the tube at full power. If you can please run your job with multiple passes at a lower power, or a lower power and slower speed please do and help us keep the laser running as long as possible.
