What is PrintNC CNC

• Description

• History

• Capabilities

  • Set expectations
  • Machinable materials
  • Links to videos of various cutting operations

Getting help from the community

• Discord

• Reddit

Customisable Options

• Frame size

  • Considerations
    • Rigidity will suffer if it's too big
    • Potential for screw whip - mitigate by using a larger screw (2010)

• Steel types/sizes

  • Bigger is not always better (70mm x 50mm is optimum weight/strength)

• Motors

  • NEMA 17 vs NEMA 23 (any greater than NEMA 23 is a waste)

• Controllers

  • PC vs MESA vs ??

• Software

  • LinuxCNC vs GRBL vs RepRap

Purchasing

• Link to BoM

• Links to 'tried and tested' products

• Considerations and alternatives

  • Cisco PSU
    • Description of different models
    • Link to Sony conversion details/images
  • Ball Screw information
    • 1605 is more accurate but speed will suffer
    • 1610 is faster and has enough accuracy for the vast majority of use-cases

• Cutters

  • Links to tried and tested
  • Types for different materials
    • Size (length, diameter, cutting width, etc)
    • Number of flutes
    • Coatings

Assembling

• Printing

  • Print profiles
  • Suggested orientation of parts during printing

• Link to assembly guide

  • Complete with annotations (for later/current versions)
  • Consider moving the Build Assembly Guide to the Wiki, as it's more flexible (links) and fluid (easier to update)

• Hints and tips

  • Squaring the Y axis
    • Pinch sticks
    • Using the waste board
    • Measuring from corner to corner
  • Paint frame on threaded wooden beams
  • Tools available for ease of assembling
    • Radius tool
    • Linear rail alignment tool
    • Linear rail punch bushing
  • Gotcha avoidance
    • Drill holes for drag chain before attaching the Z assembly
    • Drill and tap all holes then paint to avoid scratches/mess-ups
