Issue Tracker

• There should be a CNC marking on the rib for the location of the soil block.
• Front mid plate flange - does one have to be trimmed to make the hopper support fit on the ejection side?
• Are table bolt holes narrowed down already?
• Do CNC cut rings work as the shaft support?
• How much effort does it take to straighten heat warping of frame metal?

Roadmap

• Developer ISO
• Open source cylinders. Advisor.
• Open source solenoid valve. Advisor.
• Open Source Gear Pump.
• Robust 3D printing (3D printer dependency)
• Open source electronics design + workflow
• Open source soil mixer
• Lime burning
• FreeCAD construction set
• Scribus build book - on-demand publishing
• Online sales template + fulfillment instrucions for ANYONE - with license terms, attribution, and terms of sale have to be clear. Ie, anyone contributing or using can make money on this. Just spreading a new culture.
• Brick press manufacturing training
• Super-efficient CEB house instructional. Nonseismic plus seismic.
• OBI Design Guide
• 2 stage hydraulic pump for 1/2 power usage
