Basics for Advanced Extruder Operation

1. Validate USA Titan Aero Volcano operation - get all settings correct
2. Validate China Titan Aero Volcano - for lower cost sourcing
3. Validate card reader + LCD - this is a great improvement on usability and testing upon startup
4. Validate double sided adhesion of bed surface - makes sure that the surface never comes off and can stand high temperature printing
5. Validate Plexiglas electronics mounting - for tight and transparent cable management and taking up of any slack. Can we laser cut with D3D laser cutter in future iterations.
6. Validate frame assembly from welded bar. Must be done in conjunction with self-mixing epoxy method. Could be during next workshop. Needs external frame for welding. Validation shows whether this would be a practical route for remote workshops - otherwise we would need to ship frames.

Advanced Drivers

• Validate Trinamic driver quiet operation
• Validate sensorless endstop operation with Trinamic drivers
• Validate Volcano cooling fan assembly + sensor mount
• Validate insulation mounting of bed.
• Validate bottom insulation of bed

Advanced Heat

• Validate DIY heater beds with steel - 120V for scalable system.
• Validate DIY heater beds for 12V or 24V operation -
• Validate DIY heater beds with aluminum
