Introduction
Safety
- The nozzle gets hot(>210C for most printing) and stays hot if prints are paused or stopped, but only turns off if a print is completed or the user directly lowers the temperature in menus.
- Mind your hands as the motors do run on the side of the Gigabot via a rail system.
- Ensure that the heating element of the hot end does not leave the hot end while on, it will turn bright red and you will be able to smell a burning scent. If this happens, disconnect power immediately.
Equipment or Bill of Materials
- Gigabot: https://re3d.org/gigabot/
- Glue or blue tape for adhesion, better success has been found with simple Elmers purple glue sticks(Make sure to put on a fresh layer 5 minute before printing
- Blade of some kind to remove part from bed.
- Filament of choice
- PLA, Nylon, PP have been tested
Calibration & Tolerances
- The menus may be accessed to directly move the extruder assembly in X and Y directions, while the bed may move only in the Z direction.
- The print surface may be calibrated by rotating a screw against a limit switch controlling the z-calibration. Rotating the screw closer to the limit switch will cause a lowering of the print bed with respect to the hot end, and rotating it further away from the print bed will cause the print bed to be closer to the hot end.
- Under the print bed at each corner there is an additional screw(total of 4) which if rotated will either shift the respective corner of the print bed up or down.
- The print bed maximum setting on the printer is 55C and will obtain a wonderfully uniform 45C print bed surface temperature.
- The current nozzle size is 1.0mm diameter and the extruder assembly is spring based which will allow filament of 1.75mm or 3mm.
