Re: mhackney's Beta DropLit build

I haven't done mine yet but it must be very little as you only need a think film. I hope to do it tonight so will report back. Any success on this? I'm waiting for a delivery of PMP plastic petrie dishes - then add a thin layer of Sylgard. If my calculations are right, 1.5ml of Sylgard would create...

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 ho...

Re: BETA testers discussion

Not a huge deal, but IMHO the stepper wires are better off going down the right side through holes provided for them and ty-wraps. I used the center hole in the extrusion for the two end stop switch wires.

Re: BETA testers discussion

Yes, same here - I'm ready to print but need a vat. Is seemecnc just using a glass petri dish with PDMS cast into the bottom? Or are we getting a dish to use for testing? And if I need to purchase it, no problem... just need to know what the recommended situation is for this unit.

Re: BETA testers discussion

Yes, I positioned the USB connector slightly recessed to accommodate the power wires, but it is no problem getting connected to it that way.

Re: BETA testers discussion

Yup- that's what I thought. Easy enough to fix..and not a "show stopper" for us beta testers.

Re: BETA testers discussion

OK - but if you line up the usb connector on the arduino so that it is slightly recessed from the side panel, the holes in my shelf panel are not in the right spot for that. Would love to see your arrangement - mhackney's build log is exactly what I experienced here. My tape is .080" thick with...

Re: BETA testers discussion

No 10-32 metal bolt in my kit either, but I've got plenty in the hardware stock here. As for the mirror assembly, I took the plunge and used epoxy glue for the frame with a small amount for the mirror too. I used some small corner squares to insure that the sides were perpendicular during curing, an...

Re: BETA testers discussion

BTW the wiring from the top of the cabinet is shown here:

This was posted to show the risers in place, but you can see the wire routing inside the cabinet too.

Re: BETA testers discussion

Nut traps could use a looser tolerance. Several required shaving to get a nut in. Because of the way the laser cuts, sometimes on thicker pieces you get a slight widening of a path towards the back side... so it matters which way you put the nut in. One side tight, the other loose. I used that a nu...

Re: BETA testers discussion

Wow, that's a sprint build! My plate was a bit tight too. I used a file on the tabs to help the fit. Note the recent post on my thread about the lower T-slot mounts. I had mine up too high - they should go BETWEEN the plate and lower plate. I still need to change mine but fighting firmware at the m...

Re: BETA testers discussion

Got the acrylic parts in my kit. Following mhackney's build thread, I was able to unpack and build up to the end of his thread in a total of 3.5 hours. Some notes: The projector plate was a very tight fit to the sides; I had to trim material from the tabs and holes on both sides to get it to fit. Dr...

Re: BETA testers discussion

One box came today - but had two UPS "notices" via email. However they had the same tracking number - so must have been a duplicate email. My kit was complete other than a build vat - so far as I can see. If there is a "second" box it could only be the build vat... if that is ind...

Re: BETA testers discussion

mhackney: Let me know how the video was, if you followed it, I'm always open to feedback. robably not a bad idea to remove the color wheel anyway. According to Guanu the color wheel removal is unnecessary. I left it out of the video because of that. Recent print he did (without a color-wheel remova...

Re: BETA testers discussion

My kit is scheduled for Monday delivery so with any luck I'll get on it Monday night first thing after work! Yep! Arrived today! All appears to be undamaged and complete - except for a build vat??? The expandable foam did a great job of stabilizing and protecting the contents. However, without a vat...

Re: BETA testers discussion

Thanks for the new riser files - printing them now. My projector is on the way today, the other parts are printed, and I'm stocked with resins... ready for the fun of assembly and test! :D
