Hey everyone, long time lurker, first time poster. I've had a Da Vinci 1.0 for just over a year now and have been slowly making slight modifications to it to increase print quality and reliability and I thought I'd share a couple recent prints (which aren't prop related) to show the print quality that's possible with this printer.
This is my first 3D printer, so it's been a lot of trial and error. My first prints looked downright awful with horrible banding running up the sides of the print, and that was when I was actually able to get ABS to stick to the build plate long enough for the print to finish.
The most game-changing modification to this printer was my conversion from the stock firmware to Repetier Host, followed immediately by the conversion to PLA plastic instead of ABS. PLA sticks to blue painters tape on the build plate every time and doesn't shrink like ABS.
If anyone would like me to do a test print or two of your own files so we can compare print quality, I'd be more than happy to do that (as well as very curious to see the direct comparison.)
Here's a list of things that I've done to the printer, in order, as best as I can recollect:
- Added small pieces of rubber between the metal tabs that hold the glass and the glass itself - this prevents the glass from shifting around during printing
- Added shims between the linear bushings and the build plate
- Properly tensioned the X-Axis belt
- Added shims to the plastic housing of the machine to cut down on vibration and buzzing noises - http://www.thingiverse.com/thing:407970
- Converted to Repetier Host firmware
- Printed spool holder to hang off the back of the printer - http://www.thingiverse.com/thing:493912
- Stopped printing at 0.3mm! This was HUGE and is the main reason for the banding problems I had previously - 0.3mm is not a multiple of the thread pitch of the drive screws installed on this printer.
- Printed and installed new fan shroud to allow printing in PLA - http://www.thingiverse.com/thing:433113
- Insulated hotend with silicone tape to keep the hotend hot while keeping the feed tube cool
- Printed and installed print cooling fan to improve PLA print quality - http://www.thingiverse.com/thing:433148
It looks like a lot, but it's been spaced out over the past year or so. Below are the results of my tweaking - all in various colors of PLA. Coke can included for scale of the Millennium Falcon (that one stopped printing due to a clogged nozzle from cheap filament.)
