Are there any useful mods for the Da Vinci Mini besides a filament resetter? I had recently my Da Vinci Mini serviced and it is now out of warranty.

Are there any useful mods for the Da Vinci Mini besides a filament resetter? I had recently my Da Vinci Mini serviced and it is now out of warranty.
Building a case right now. It is xyzprinting 3rd generation product, I don't see much need for mod besides E3D mount and layer cooling fan.
P.S. Technically, does RAMPS conversion count as a mod?

I would count is as more than a mod. Major rebuild. ;-)

That will be motherboard replacement and LCD/SD card reader MOD for mini

+1
Can someone point me in the right direction for doing a major rebuild? I am very new at this. I love my mini. I just hate to part with it.

If you have mini, read this in additional to see the difference between mini and Jr.

Awesome. I will read those links and but the stuff I need to do a rebuild.
Speaking of the Mini, has anyone attempted to do any kind a of duct fan mod that works with the stock housing? I stumbled on this design, but while the fellow said it worked well, he never shared any further detail.

I sure could use something to help cool the layers. Even something auxiliary that's stand alone with positionable jets would work. I'm surprised I haven't stumbled on something like this out there?
Agree, would be nice with some small plastic thing to lead air to the nozzle. I don't believe in mounting another heavy fan on the head assembly.
@Teddyz, agreed. While you do see alot of guys running Hotend mounted auxiliary fans, you just have to know there's a trade off with the extra weight.
I have actually been trying to research the route of using positionable arms based off of this item: https://www.thingiverse.com/thing:1407852 . Here he is using the adjustable arms to vacuum, but surely it can work in reverse to direct air out. I'm thinking four of these, mounted stand alone outside of the printer at the corners of the table will do the trick. It's really a function of coming up with a base and the air. Perhaps a tiny airbrush compressor might work, if I can find one quiet enough. I have heard of some folks trying aquarium pumps in other ways, but I'm thinking you'd need one big honking pump to pull this off. However, I do think aquarium adjustable valves could be leveraged.
They weight of the fan that is the size needed is nearly nothing in the way it would be used. There would be no real weight gain that would affect the machine function.
Those fans in that size only weigh an once or so at most. If you are tuning your system so that the weight of one of these fans would impact it then you are wasting your time really as no FDM 3d printer will reach the precision and/or speed you are looking for.
As for remote air the issue is that it must always be directed at the layer just below the nozzle. Unless you build a system that is mounted to the carriage or gantry there is no way to keep it directed at that layer unless you sit there and move it manually during the entire print. Having it just blowing over the bed or print will cause accelerated cooling on the outside while the inside is still very hot and this will cause warping and layer separation.
This is why most ducts and fans you see for layer cooling are angled or have ways to control the airflow so it is only on the end of the nozzle and the first layer.
Yes, no doubt that there are more optimal routes, but the problem for the Mini is, the Jr duct piece interferes with the outside case. And, this one mockup I shared earlier was never fully developed. So to date, I haven't found a single fan mod that has been developed that works with a stock Mini with the stock case and stock hotend.
I found that just using a small 6 inch fan blowing from the rear across the bed forward made a drastic improvement in the quality of the prints. No doubt, with a better solution, even better results can be had. My first post was specifically solicited to see if anyone had pursued this on a relatively stock Mini, without a bunch of mods.
