If you’ve had to calibrate the bed of your Da Vinic 1.0, you will understand how this is a painful process. To make things somewhat easier, consider replacing the stock thumbscrews to something a little more manageable.
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.
