| ==Inkscape w/ save as .gcode==
| |
| In order to get the OSE Linux platform software Inkscape to be able to save as .gcode, from the location you put the download of gcode for Inkscape [https://github.com/arpruss/gcodeplot] you open the terminal. Your do this by clicking the >_ box icon home symbol ~ then / the location. You see mine was located at ~/Desktop/MARCH STEAM/pen plotter. then type the comand '''sudo cp -rv''' name of the directory to transfer, here it is 'gcodeplot-master' it is the start of directory and all the contents so '''/*''' to the location that Inkscape will access it, which on my system is 'usr/share/inkscape/extensions/'

| Jessica Leete is a designer, a licensed landscape architect, sculptor, urbanist, community catalyst and ecology educator. She is the founder of Boston dot dash Studio. The studio is the space for convergent thinking, design process, and construction regarding land and the systems that engage it to create regenerative solutions that reverse environmental degradation, are resilient, adaptable, and (through an engaged design process) provide training for an empowered community. The studio is about realizing solutions, the act of making, and how the process of design can affect positive change. The first of many, she encourages you to join the movement, start your own (location) dot dash Studio. A member of the Global Open Source Hardware (GOSH) movement, her particular interest lies in developing and making ubiquitous, open source hardware and technology for environmental metrics. To that end, she is collaborating with Open Source Ecology to enable universal access to collaborative design using open source toolchains.

| After powering on your computer, but before your normal operating system starts, you can access your boot settings.
| |
| Boot target computer from USB Stick
| |
| First, configure the BIOS to prioritize booting from a USB drive. In my case, I'm installing on an unknown desktop running Windows 7.

Four holes on back of screen appear to be same dimension as mounting holes on Rpi though different sizes??? Current concept build has plenty of room for adding parts

| Prep plate by using fine steel wool or gentle abrasive like comet to remove all oil etc. DO NOT TOUCH SURFACE, can leave fingerprints on etch. Transfer the PWM Modular Control for light dimmer (welder in development) sketch Tom developed to plate. Traced sketch and punctured with ball point to use as template for permanent black marker. Made dots through template then connected them. (Note multiple passes and streaky marks does not work)

why the phonetics of this word aren't enough (lin ex), one must use sudo nano to communicate with it. Sudo stands for super user do which gives users the permission to use commands at the most powerful root level of the system. Nano is the text editor, installed by default on Ubuntu, Nano is an ncurses-based editor (which means it must be run from a terminal window) that requires code reference unless you are experienced. Googling will absolutely work once you are familiar with what you are looking for. If you are running the OSE linux platform on a thumbdrive consult others @ making and saving modifications. This link was great with the basics of linux code language [11] You can verify the presence of nano by typing nano --version in front the terminal promt yourname@yourcomputer:~$
like any language, one must learn the swear words first like sudo cp -rv /* , where cp means copy
recursively -rv, meaning including all sub folders, forward slash / is the beginning of an absolute full path to the asterisk * which in terminal means everything (code 42)... the detail is in the space /* which is literally the entire root directory of the operating system rather than a particular foldername/* meaning entire contents of that specific folder to a location. So don't blank space, forward slash, asterisk anything unless you want to sudo rm -rf remove all unwanted copies of root directories by using the up arrow to repeat the command many time.
Moral of the story, be careful with
