Ive noticed alot of companies marketing 3d printers use the tower file to 'wooo' there customers in.

Ill give it a shot at .1 over the next few days and see how I go.

Ill post some pics when/if I finish it.

Cheers

Why isn't my first layer temperature setting working? It prints the first layer at 195 degrees, regardless of the layer temperature settings in Slic3r, AND my printer settings in repetier !

Is there a default value in the firmware that sets the extruder to 195?? Anyone see this happenening? Watch the actual extruder temperature in repetier when you prints stuff...

Still looks pretty good! I also don't have a digital camera and rely on my iPhone, the lack of manual focus is extremely irritating for close detailed shots.

Interesting results.
Had alot of strings to clean up under the chin and ears.

The main thing is that just above the eyes the layers shifted over about 4 perimeters, kept printing up about another 25 layers then shifted over again. I have seen this before and have never been able to explain it.

I believe the motors get really hot on a good day, so a 27 hour print on a really hot day I think has caused the motors to miss align or something like that, it is uniform around the part so it wasnt caused by the print shifting on the bed or anything.

Pictures attached, only taken with an iphone..believe it or not I actually I dont own a digital camera...weird.

Im going to order a 40mm heatsink for the x axis and see if it corrects this shift I see from time to time.

I did a 75% scale .1mm of this one with 5 shells, no fill. 9hr, 15mins

How did your Yoda turn out? I did a big one as well and I don't think it looks nearly as good as yours.

Will get some good shots when it's done. Hopefully goes ok, I could see the brim was slightly lifting, fingers crossed it stays put.

Anyone got some other stl's like this I could try at .1? It's hard finding nice clean stl's I can scale up and print like this...they always tend to have holes in geometry or large overhangs. Haven't got around to mastering supports yet.

I futzed around a bit with a nut cap, and finally settled for the simplicity (and ugliness) of just hot gluing it in place.

mac,
kendalls 2 part cap should work in any rotation I thought. I was having issues with the cap lifting a bit though so I switched it out for this z-nut hugger and it works with my nut rotation, but I had to put it on upside down with the tab to the right.

That yoda is huge!!! Please give of some real nice closeups when its done

That looks like it's almost a kg of plastic by itself. I've never seen Yoda at that size, and certainly nothing that big at .1mm. Get some good lighting when you take the finished photos and get some good detail closeups.

Can't wait to see it all finished.

I drank beers with a guy from Chicago while on kona earlier in the year. All he did was talk about how cold it gets there.

Its saturday morning here, just popped into to see the printer...has been running over night, already been running for 24 hours, another 3-4 hours to go. Lucky actually, its going to be 38 degrees here today (100 fahrenheit) so the office is going to get pretty warm, should be finished by the time the heat gets here.

Progress looks good, there are dark lines that run through the model, im assuming these are probably whats left of my z wobble, the nut and hot glue seem to work really well. I found kendalls nut cap didnt suit the rotation of my nut once locked into place.

The detail from printing at .1 on the yoda is very cool, nostrils, mouth, eyes...its almost creepy

Plenty of strings around the chin and ear, will get it cleaned up on monday and post a finished photo.

Straight off the printer, I just peeled the brim off. I have a nut hot glued to my z screw to reduce the z wobble but it is still noticeable on the sides if you look closely. Still very happy with the result
