4/10/16 The Lyman/Mullier extruder is getting an overhaul to make it faster, more user-friendly and significantly less expensive than the original. High-speed testing revealed that 3000mm/min or approximately 10 feet/min for 3.00mm filament is achievable, with accuracy ranging around +/- 0.2mm but capable of improvement. New firmware is being written to interface with an Arduino DUE and a high-resolution TFT Touch screen, rendering the RAMPS/MEGA obsolete. The Filament sensor was revamped using a Teensy microcontroller for ultra-precise filament width measurement - up to 1200 times per second! Notably, it has overcome outside light interference except for direct sunlight. The audit-trail function has been included in the firmware, mirroring the feature found in the Mackerel software. A Windows application is also available for users to record and analyze data as needed. Work is ongoing, with prototype iterations in place - we're currently at version 5. The vertical orientation appears to be producing better results than its horizontal counterpart based on current data trends. 12/29/16 The image of the sensor's feedback has been added to demonstrate its functionality
