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.
Operation & Procedure
- Download a slicing software such as [Cura] and then set up your machine settings and printing profile. Example machine settings and profile are both shown below.
- Export Gcode from cura to a microSD card and insert said card into the Gigabot controller.
- Verify the print settings and tune the printing parameters more specifically for the printed part needs via menu options. Some options in the menus are shown below.
- Ensure the printer is calibrated correctly by doing a test print with zero flow rate and watch the Z-distance between the nozzle and the print surface. An ideal Z-distance is about 200 microns.
- Check the print bed for adhesion, as in apply glue in stick form or blue tape if such is needed as examples.
- After verifying the nozzle temperature, bed temperature, speed, fan rate, and flow rate you may begin printing via the print from SD on the main menu.
- During the print the print parameters may be modified. Specifically effective is the nozzle temperature, speed and flow rate.
- After printing is completed ensure that the nozzle, bed, and fans are all off.
