Morning: Worked on PiBase CAD. Not likely to be useful as some of the ports will be needed internally, but a good excercise in fully constrained drawings.

Researched Pi specs and screen interfaces and cabling.

Afternoon: Ran g-code generation in inkscape and sent to D3D. Printed updated fan/pen/prox holder for install at later date.

D3D Issue-O-Day:

Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?

Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.

Researching wiki for current CNC mill progress, looking for previous CAD that is usable to attach to D3D-U. Found firmware info and spindle mount and Full working prototype from earlier D3D

Good Videos for FreeCad: Slicing parts from assemblies that are already created and have had their layers "flattened". FreeCad 0.18 PART WB using SLICE and SLICE APART FreeCAD of a simple screwdriver - drawn and printed.

Reviewed Arduino homemade documents and photos from Texas.

Reviewed Wiki usage documents etc. Ran calibration prints and temp calibration print in D3D-U. Youtube tutorials on inkscape -> gcode. Pushed fresh install of mediawiki to sandbox server for learning purposes.
