I am retrofitting a Printrbot Simple Metal 3D printer with tools to allow for serialized printing. Then I hope to release the use of it to schools. For Free.

Slic3r Config

Cereally Automated Build System

The testbed for train_rec was a success. Rather than use the length of the pop-bar as a lever to pry the piece off of the bed, I think its better to twist the bar along the length to push the 3d printed part up.

Milling the "production/testing" bed is next on the list.

Hardware Configuration

Current

• Killswitch, both remote and local

Planned

Immediate:

• Detect use of emg stop button in arduino
• Pop-bar and channel
  • servo structure
  • Removal arm. Can also double as print surface cleaner?
• New GT2 belt mount for print bed

Later:

• Use accelerometer to detect grinding gears/belts?
• larger print surface to maximize hotplate use
  • Longer steel rods
  • more GT2 belt
• Print a GT2 belt clip? Zipties suck
• Better webcamera setup
  • different embedded computer?
• Filament absence sensor
  • Just look for the circuit completion when the extruder rollers connect?
• Birdsnest detection
• Print adhesion detection
• General failure detection
• Detect belt slipping?
  • Use linear encoders? I mean, they really ought to be standard on a 3d printer.
• Heater dead-mans switch
  • Ping the webpage?
  • snoop on gcode over serial?

Printed Upgrades

Images incoming.

• Extruder Fan Duct
• Filament Guard
• Filament Clips
• Spool Stand
• Filament Cleaner

Upgrades to be printed:

• Fan mounts for motors
• GT2 belt mounts for print bed?

Amazon is an OK outlet for GT2 gear/belt parts for the X-Y motion
