We bought a Da Vinci 3D printer for our students but have a problem and some help would really be appreciated. We're newbies at this.
We're using the white filament cartridge that came with the machine and we've calibrated and leveled the table. When we try and print one of the sample objects the machine starts OK. It warms up and then prints the purge line which comes out OK. It then moves to the object starting point and starts printing. The problem is that the head and table move but no filament is extruded. We can see the knurled feed wheels in the print head turn, and we hear a regular clicking sound, but no filament is extruded.
What is going on?
Thanks
The clicking is not supposed to happen. It means the filament is slipping in the drive gears. This being caused by the middle of your bed being warped and higher in the center than the edges where the purge line prints fine.
Since you have a passing calibration stored I would do the manual calibration listed at the top of this section. Just start from the point where you start a sample print then turn off power as the purge line is printed.
Rather than focusing so much near the screws, move your measurements in closer to the middle. You are wanting to reach some what of a compromise between the height differences.
Unfortunately this is a common problem with these printers. An easy fix is to go to a glass shop and have them prepare you a piece of 1/4 inch or 6mm tempered glass yhat is the sam dimension as the stock glass. The metal tabs that hold the stock glass have long enough screws that you can just put the new glass right on top of the old. Snug it down, then adjust the bed screws down far enough you can run the manual calibration again for the new glass. Again skip the section at the beginning where you get a passing auto calibration. Once you get pne of those to pass you will never run it again since it does not set the correct values on the first place.
Printing since 2009 and still love it!
