This guide serves as a complete technical summary of every piece of information provided by Invent-a-Part to the community over the last year of updates. If it is missing anything please feel free to add in the comments.

The purpose of this guide is to act as a quick reference, and refresh people's memories - As some of this stuff is quite old. It should contain everything officially confirmed by IAP/Michael on Kickstarter/Instagram.


Electronics

caption


  • Heated build plate contains red LED’s which illuminate when the bed is heating with built in thermistor.
  • The standard heated build plate measures around 3.6 to 4.0 ohms.
  • Heat up times for Heatbed (Heated build plate)
    • Standard: 65°C = 3-5minutes, 110°C = 7minutes
    • RigidBot Big: 65°C = 4-6minutes, 110°C = 8 minutes
  • Heated bed power does not go through physical power switch - is switched via a transistor on mainboard.


  • Board based on Arduino Mega2560 & RAMPS 1.4 boards (schematic PDF) (schematic 1200dpi) ATMega2650 (pin mapping)
  • Custom Marlin firmware
  • 5V pins available (limit switch connector a good option)
  • No 12V supply available
  • USB Socket rated at 300mA
  • Fan1 connector J4 on extruder breakout board for object-cooling fan.
  • Fan1 connector is PWM-controlled and can be completely controlled by software.
  • Fan2 is connected directly to 24v, and thus is always on. This is the fan to use for the extruder fan.
  • Easy access to I2C bus for future expansion.
  • Dip switch were planned to select 10x10x10 or 12x16x10 on the board itself and dual/single extruder but does nothing. These switches were not implemented on the rigidbot.
  • 3 limit switches, however can use upper & lower limits (6 limit switches) so you can make a custom sized” rigidbot.
  • Support for a multi-coloured LED strip
  • Large 4 layer board
  • Dual extrusion ready


  • Optional LCD/USB Board contains the following scripted features:-
    • Print from USB
    • Bed leveling Script (will run a program which automatically moves the head to the four leveling positions on bed)
    • Change Filament script - to load/unload material
    • Pause/Resume script
    • Manual Jog - manually move printhead in xyz positions.

Mechanical

  • Except for one allen wrench, all necessary tools are included with kit for full assembly. The missing allen wrench is for the belt tensioners. However a small philips screwdriver & a mallet for constructing the frame are also recommended
  • Polymer sleeve made from PTFE/Teflon - recommended not to exceed 250°C - 1/4" (6.35mm) outside diameter, 2mm inside diameter, ~16.65mm length (varies depending on exact thickness of mounting block, PEEK insulating block and heater block.. should have no gap between PTFE tube and either mounting block or heater block)
  • Z-rod will require cleaning if you're assembling yourself
  • LM8UU Linear Motion Bearings (11 per printer)
  • Linear Rods - Chrome Hardened Linear Rods (8 per printer)
    • a user reports: "the long rods, 2 of them are used for the build plate and 2 of them are used for the extrude head. The four short rods go in your left and right frame rails for your z axis motion/up and down"
  • GT2 Pulley, 36 teeth
  • GT2 Belts
  • Injection moulded corners with threaded inserts in places to assure accuracy and reduce the amount of maintenance required.
  • Smooth rods are 8mm in diameter
  • Tubing is standard .75inch / 19mm bar stock.
  • Frame drawing1.png

  Mechanical drawings for the RB regular frame.
  • RigidBot design will be available in STL format.
  • Aluminium hot-end with brass extruder tips with a 0.4mm nozzle diameter M6 thread
  • RB build plate DXF file File:RB3 Bed.dxf.zip
  • RigidBot 10x10x10 Dimensions: 19" x 16.5" x 16" (48cm x 42cm x 43cm)
    • LCD adds 3/4" depth
    • Build plate can extend up to 2" in front of the frame, and 2" behind the frame during printing
  • RigidBot 12x16x10 Dimensions: 24.5" x 19" x 16" (62cm x 48cm x 43cm)
    • LCD adds 3/4" depth
    • Build plate can extend up to 3" in front of the frame, and 3" behind the frame during printing

Recommended Settings & General Specifications

  • Print Speed: 75mm/s (suggested speed only. can go faster)
  • Filament Diameter: 1.75mm
    • If you are using a filastruder to create your filament, the filament is often between 1.69-1.71mm diameter (due to the size of drill bit used to produce the nozzle)
  • Maximum temperature: 250°C (using the supplied extruder)
  • 100 micron layer resolution
  • 0.4mm nozzle diameter
  • RigidBot kit weight 15KG (35lbs)
  • RigidBot Big kit weight 20KG (44lbs)
  • +/- 0.0762mm in the x/y axis for tolerance. (.003")
  • 10x10x10" build dimensions = 254 x 254 x 254mm
  • 12x16x10" build dimensions = 304 x 406 x 254mm
