This page contains my notes on 3d printing.
A good nozzle is required for accurate printing, smaller sizes have neater finishes but take longer, where big nozzles do it quicker but the layers are more visible.
Here are some nozzles people seem to recommend:
- E3D Volcano
- E3D V6
Printrun/Pronterface is a good program to connect to the printer and control it from your computer.
Slic3r is a program for imported models and configuring them for the printer and exporting the print-ready gcode.
My recommended fill settings are:
- Wall layers: 3 (tested to be the apex for strength)
- Top and bottom layers: 5 (I have found the default of 3 not quite enough in most circumstances)
- Fill type: Rectlinear (tested to be the strongest)
- Fill percentage: >30% (anything less is just too weak)
- Fill speed: ?
Retraction is where the extruder runs in reverse to prevent plastic coming out when it is moving, this prevents issues like stringing.
Try connecting THE 2 motors in series and adding 2 more on the other sides in series (to support the entire bed) and reduce stepper distance to account for the increased load.
The two steppers must be adjacent to stop the board flexing.
