3D Printer Critical Path
Changes after the Open Source Microfactory STEAM Camp
- Add WiFi SD Card as a turnkey option.
- Remove spacers and build them into the 3D printed pieces
- Possibly expand the half-carriage to allow longer belt pegs. Make belt pegs only one type.
- Add Z axis balancing
- Add skew correction for y by virtue of stops
- Tune the heatbed for 450W
- Put a cover on the power supply for shock hazard
- Document the stepper driver voltage decrease
- Modify menus to make babystepping more accessible
- Determine if 1/16" steel is acceptable for an 8" bed
- Develop 12 printer production engineering for $1000/day net revenue for $10k/month revenue model at half-time engagement
- Publish new manual
- Develop online course
- Run 50 STEAM Camps until June 2019
March 4 2019 Week
- 8" bed version kit release, 12" frames for easy USPS ship
- 12" bed version kit release
- 36" bed version kit release
- And everything else in between.
2019 - Sep Refocus
2019 - August Refocus
2019 April Detail
- Rationale - go to 120V heat bed to reduce power supply size.
- Don't include TMC2130 initially as that will take time to optimize, even though it gets rid of the end stops. Use TMC2208 now.
- Include clean wiring
- Include 3D printed corners
- Building new heated bed allows for a high performance printer
- With 3D Printed control panel, electronics become simpler for builds
- Silent operation is a good upgrade
- Clone titan aero is lower cost for lower cost versions
3D Printer Modules
Getting very clear about modules allows for very clear division of labor in a collaborative process.
