Da Vinci Extruder Power Connector Fail

The small quick release connector for the extruder heater recently failed. This was discovered half way through a print when the extruder stopped heating.

Initial thoughts were that there was a software bug due to the extruder failing to extrude filament after 12 hours of continuous operation. However, some fiddling with connections revealed that the plug and socket connection was the culprit.

Replacing the stock connector with something more robust is straightforward but the process is a little fiddly.

3D Printing – Rafts

If printing a model that has multiple small pads or islands contacting the print bed, there is a high risk that these will catch the print head and tear off. Once this happens, the print is difficult to recover and you need to being again. No amount of glue seemed to help the latest attempt from tearing the pads from the print bed.

To solve this problem, a raft  was used to support the model and finally there was some success.

 

3D Printing – Da Vinci 1.0 Performance

3D printing allows you to make rapid prototypes or final creations. However, as you’ll soon learn, what you model up is not exactly how your print will turn out. A good example is when printing holes in your project. Due to a variety of factors, the actual printed hole diameter will be different to your 3D model. Printing a standard on your 3D printer will allow you to understand what your machine can actually do.

First in the beginning of several articles, we examine how printed holes will be different and how you can compensate for the difference.
