	The machine needs development. For a Master's Thesis, there is a number of technical developments to be made. Advanced topics would include designing and building an open source manual hydraulic control valve or electric solenoid valve. The latter is $800 for the current machine, but could be produced for $200 if open source. Easier topics would be to refine some of the design elements. Other topics could include more of a production engineering / product development angle: developing the machine for production, especially for flexible fabrication - and turning it to a marketable product. On the controls front, there is the controller and code to refine, and on the CAE side, there is structural analysis to be done. Further, we are developing the CNC torch table for automated production of the machine, including oxyhydrogen cutting for low resource environments which may not have acetylene, but do have access to water for generating oxyhydrogen - such as Africa.

	#Catastrophic fault correction - the only catastrophic (meaning it takes 3 hours to correct, or as little as 2 hours if started from scratch - is when the press foot location ends up above the table, and therefore the drawer cannot move. This is easy to correct in software, but cannot be corrected easily in manual control operation. Thus, the geometry must be corrected in hardware. The only thing left is to use something like 3/4" steel plate instead of 1" if the press foot comes out 1/4" too far up, and then spacers are used to correct the rest. Spacers can be cut from aluminum flashing, or any spacer material.		#Catastrophic fault correction - the only catastrophic (meaning it takes 3 hours to correct, or as little as 2 hours if started from scratch - is when the press foot location ends up above the table, and therefore the drawer cannot move.

			==Before, During, and After Units==
			*Before the workshop - present people with instructions for downloading FreeCAD and WebGL designs for full 3D manipulations, including exploded part animations. Provide LAIs, EPAs. Provide design rationales, workflow instructions. Even an intro video to manage expectations, such as: are you ready? No you're not...unless... Send this out 2 weeks beforehand so people can study it. This will prevent any issues with people who are looking for additional understanding, but where time does not allow for more in depth study during the workshop - as the workshop is primarily hands-on - and the theory can be studied beforehand or after.
			*Before unit - literally an XM Workshop Manual needs to be prepared - where those who have time to study can do so.
			*Before unit - leaders who actaully read the manual - are encouraged to step up to leadership positions
			*During pre-workshop unit - design welding, torching, and grinding tests, where people go at it, and in 1 hour, speed-date a welder, torch, grinder, drill press, and other tools.
			*Before - design an open source welder, and possible Power Tool Construction Set which relies heavily on thick ABS-metal composite parts (including for band saws, etc)
			*Develop the heated build chamber ABS printer for heavy parts.
