Cnc Plasma Plans

[Dawnell Sechler]

Thisis a set of plans to build a 3 axis budget CNC plasma cutter using metal tubing and 3D printed parts. Plans include 3 dimensional drawings of all parts, .stl files for 3D printed parts and a complete bill of materials list to complete this project. Open source firmware and software will need to be loaded onto the Arduino to complete the electrical function of the machine. This process is detailed in the instructions.

If you have all of the bill of materials on hand, this will take about 1 day's time to build and assemble the mechanical portion of the machine. The electrical will take about 1/2 day depending on your experience.

Today, under the leadership of President Trump, the Office for Civil Rights (OCR) at the U.S Department of Health and Human Services (HHS) issued amended guidance on how the Health Insurance Portability and Accountability Act of 1996 (HIPAA) Privacy Rule permits covered health care providers (e.g., hospitals, pharmacies, laboratories) and health plans to contact their patients and beneficiaries who have recovered from COVID-19 to inform them about how they can donate their plasma containing antibodies (known as "convalescent plasma") to help treat others with COVID-19.

OCR added health plans to the June 2020 guidance that explains how HIPAA permits covered health care providers and health plans to identify and contact patients and beneficiaries who have recovered from COVID-19 for individual and population-based case management or care coordination. The guidance also emphasizes that, without individuals' authorization, the providers and health plans cannot receive any payment from, or on behalf of, a plasma donation center in exchange for such communications with recovered individuals.

This announcement builds upon President Trump's call to action and existing partnership with commercial labs, insurers, providers, and pharmacies to send communications to individuals who have recovered from COVID-19 encouraging them to donate their convalescent plasma. This guidance to health care providers and health plans also complements the Food and Drug Administration's (FDA) recent issuance of an emergency use authorization (EUA) for investigational convalescent plasma for the treatment of COVID-19 in some hospitalized patients. The FDA has concluded this product may be effective in treating COVID-19.

"In response to the President's call for Americans who have recovered from COVID-19 to donate their plasma, OCR clarified how HIPAA permits health plans to contact their beneficiaries about plasma donation opportunities," said Roger Severino, OCR Director. "We will continue to use every tool at our disposal to beat this virus and keep Americans healthy," he added.

The National Academies of Sciences, Engineering, and Medicine are private, nonprofit institutions that provide expert advice on some of the most pressing challenges facing the nation and world.

Fusion offers the prospect of virtually unlimited energy. The United States and many nations around the world have made enormous progress toward achieving fusion energy. With ITER scheduled to go online within a decade and demonstrate controlled fusion ten years later, now is the right time for the United States to develop plans to benefit from its investment in burning plasma research and take steps to develop fusion electricity for the nation's future energy needs. At the request of the Department of Energy, the National Academies of Sciences, Engineering, and Medicine organized a committee to develop a strategic plan for U.S. fusion research. The final report's two main recommendations are: (1) The United States should remain an ITER partner as the most cost-effective way to gain experience with a burning plasma at the scale of a power plant. (2) The United States should start a national program of accompanying research and technology leading to the construction of a compact pilot plant that produces electricity from fusion at the lowest possible capital cost.

A PDF is a digital representation of the print book, so while it can be loaded into most e-reader programs, it doesn't allow for resizable text or advanced, interactive functionality. The eBook is optimized for e-reader devices and apps, which means that it offers a much better digital reading experience than a PDF, including resizable text and interactive features (when available).

I would love to have Plasma Bigscreen, if not in my 55" XIAOMI P1 ARM SoC, in my X86 Manjaro, switching between normal Plasma and Bigscreen, to be able to use it with a TV remote, even if I have to use 2 remotes.

PS: Some Android software to replace Android in TVs (and be able to reinstall it), even if it is with the need of plugin some USB storage would help Manjaro plasma bigscreen a lot. Or at least one agreement with some brand to come pre installed.

So I recently acquired a new plasma cutter, which is totally going to revolutionize my workflow. But in order to use these guys you need a surface for your material that won't reflect the arc back towards the workpiece, so I designed and build this guy, which has removeable slats that can be easily removed and replaced.

The next step was probably the most tedious, I had to make a little 45 degree angle jig with two wood blocks so that I could cut the top of the frame half way through to allow me to drop in the 1/8" slats in the top. This worked well but took a little while as the saw kerf is a hair less than 1/8" so I had to tap it over a hair after each cut to widen it.

Tools used:

Testing everything out--success. After this I welded up a length of 1/8"x1/2" flat stock below the slots so that they would sit flush with the top. I did this because I'll often be cutting pieces larger than the table and--well, it just wouldn't work well if the work surface was below the frame.

I did some shopping both online and locally and I surprisingly found that the best quality and price I could find on casters were the little locking 3" casters they sell at home depot--so that's what I used.

Using my new Lincoln Electric 375 air plasma cutter to cut out the pieces for the funnel. In the past I would have used my Beverly shear for this--this is so much better, the edge looks like a factory cut!

And the handle. No cart is complete without a handle! Here I actually used 3/4" solid for the actual grip and used more 3/4" tubing for to connect it to the cart. I just can't stand seeing open tubing, and I hate cutting and welding plate to seal it, so--this was the easiest way to do it.

I welded on three hooks, two for the torch and power cable, and another for the ground clamp. I also added a tab for the ground clamp that I made with a 3" off cut of 1"x1" angle iron.

This thing is going to get abused, so there is no reason to paint it, plus paint doesn't conduct electricity. I've found that coating steel with boiled linseed oil does a surprisingly good job of keeping rust at bay. I figure if I hit it with some oil every 6 months or so it'll be fine.
