The posts on the Anti-Backlash Nut Carrier need a redesign. Mine, in PLA broke coming off the printer. Can they be "wing-like"?

I'm going to print at .1 mm for now - but they really broke quite easily.

Re: BETA testers discussion

EDIT: I have an InFocus LP335 and the lens is on the right of the projector. The unit hangs off of the right side of the machine about 2 inches. Is the projector base plate reversible? I'm thinking of flipping it over. From my view it is... but trial fit it first and see how it goes. I think the ...

Re: Stack's Droplit Build (Beta Model)

I used a dremel to shift the Arduino about 3/4" towards the front. The Arduino + the Gray Bell + the power supply = no fit. 12-New Arduino Location.jpg I got a 6-pin Video Card Cable from Frys and twisted the ends together so that more amperage could be drawn to the Arduino if needed. Note that I ...

Re: Stack's Droplit Build (Beta Model) Arduino Install

One thing I had to do - since I don't like screws sitting right on top of the Arduino board is that I ground down some standoffs. 6 - Grind Down Standoffs.jpg Note that I have not installed the Grabl shield - but I did do something else. I installed an eight-pin connector. I don't really like ...

Re: Stack's Droplit Build (Beta Model) - Remove UV Filter

Remove UV filter from Optoma W316. Two screws to take off the lense assy - one on the top and one retainer on the assembly. Then two on the front of the assembly.

Stack's Droplit Build (Beta Model)

Got my kit on Wednesday. If you're going to paint the edges, be sure to prime. I didn't - so I went through three cans of Rustoleum.

I thought the green edges would make the white case and blue plexi covers look schnazzy.

Hours: Unbox and Paint: 2.5

I'd be interested in seeing your progress. I'm definitely thinking that a whole lotta settings in software are going to have to be changed. Also, I'm wondering if the extruder is going to keep up. It should - but it will be interesting to find out about your experience. Sorry that I don't have any ...

Curing Large Parts by Changing Device Geometry

Over the weekend, I was thinking that larger parts could be cured by changing to larger petrie dishes, substrate location (bed), and projection dimensions. It's my guess that higher resolution (1080i/p) projectors would have to be used - which then led me to trying to figure out the differences in ...
