Topic: Thingiverse: 66936 - Can it be printed?

I have been trying to print this:

http://www.thingiverse.com/thing:66936

I already tried the following:

- Leveled the bed the best I could
- Adjusted the Z-screw to the point that the first layer can stick but without squeezing too much
- Checked the extruder calibration and the flow rate (using the box)
- Reduced the flow rate below the calibration number
- Tried slicing with  Slic3r and KISSlicer

As you can see there is not enough distance between the inner and outer gears.

Thank you in advance for your input/help,

CB

I've tried printing the Gear bearing, and all it does is stick together and cause headaches, I'll try some time in the future, but for now,  I'm gonna stay away.

try this one. http://www.thingiverse.com/thing:53451

Do the flow rate calibration again. Make sure it is dead on.

it's been done by a couple people here and have posted videos.  search for the word emmett (original designer on thingiverse)

Oh yeah, the last time I tried was pre calibration, time to try again...

From the blog... "When you are printing at .3mm layers, a good Width over Thickness Ratio is 1.4, meaning the thread is 1.4x wider than its height.  This would be .42mm..."

Width over Thickness Ratio is 1.4... Does it apply for 0.1mm also? so the wall thickness has to be .14mm?

Thanks,

CB

Re: Thingiverse: 66936 - Can it be printed?

since the extruder tip is .35mm you can't be smaller than that in the x-y plane only the z plane gets smaller.

Re: Thingiverse: 66936 - Can it be printed?

I've printed it and it works but I had my extrusion multiplier down 15% lower than normal. There is a bit of slop I might try bumping it up a little to get the tolerance tighter.

Did you use Slic3r or KISSlicer? Could you please share your settings? I tried today using Slic3r 0.9.9 and I noticed there is continuity of the fillament between the outer gear and the inner gears for every single layer so that is why mine doesn't spin.

Re: Thingiverse: 66936 - Can it be printed?

You can customize the original file, in which I would recommend increasing the tolerance, as it increases space between the inner workings. I think I printed mine at .3 tol as opposed to the original .15 (I think it is?) I've had two semi successful prints. The first one caught a lot due to my banding issues, the second - fourth I failed due to bed adhesion & getting used to slic3r over pronterface, then the last one printed fine, just a little sticking which can be fixed with a 1/4" allen bit in a drill and 5 minutes of high speed turning.

Here is a link to the one I customized per my mentions above:

Re: Thingiverse: 66936 - Can it be printed?

I printed it at the original tolerances using KISSlicer. Spins very easily.

CrazyBear, I will post my settings in the KISSlicer thread.
