LittleRP2 Information
Posted: Thu Feb 16, 2017 1:24 pm
Hello LittleRP'ers, thought I would give some info now that things have finalized for the most part.
The LittleRP2 will be a real thing shortly, consisting of source files, kit availability, and parts for those self sourcing.
The LIttleRP2 is still heavily based off the LittleRP so that there is an easy upgrade path for those with a LittleRP, the main differences are the width of the machine, the vat design, small incremental changes, silent stepper drivers, astrosyn vibration dampners, hinged hood, no glue hood option, mgn12 and 2mm pitch leadscrew options, etc.
One of the more exciting additions is the support for (2) 1080p projectors that will let you get 25x/y micron, the Acer X152H and the Optoma HD37, neither of which suffer from the optics issues of the P1500 / H6510BD projectors. (This support can be added to the LittleRP as well)
The other major addition is the option for increased build area, both in height and in x/y dimensions. There are now options for an extra 100mm in Z height as well as almost doubling the x/y dimensions.
The core product is still the smallest of the configurations, the short, small build area, high resolution version. However people now have options, you can change the LittleRP2 from small build area to large build area in a few minutes by rotating the projector base to the rear, installing some spacers, and swapping out the mid plate / vat assembly.
The source files will be available at the same time I allow ordering of the kits for those who want to build their own. I will also put together some upgrade kits for those who want to just buy the parts needed to convert. The store will start transitioning away from full kits and offering more components to make it easier for those building their own LittleRP2. I plan on working on modifications to the design in the future, offering LCD support etc. and the wider platform will better allow for this.
I am also happy to announce that the LittleRP is now a certified OSHWA ID:US000060 (Open Source Hardware Association) project, I am a firm believer in the Open Source community and would love to support you if you wanted to produce and sell kits yourself.
If you have any feedback I would love to hear it.
For some actual numbers:
LittleRP2 - 85mm / 185mm z travel ( regular vs. tall)
Acer x152h - 49x28mm (25 micron x/y) - 72x40mm (37 micron x/y) (2 positions available)
Optoma hd37 - 49x28mm (25 micron x/y)
Acer p1500 / h6510bd / viewsonic 7820 - 72x40mm (37 micron x/y)
Acer p1283 / x1240 - 60x45mm (50 micron x/y)
LittleRP w/ Expanded Build Area - 80mm / 180mm z travel ( regular vs. tall)
Acer x152h - 90x50mm (48 micron x/y) - 120x80mm (67 micron x/y) (2 positions available)
Optoma hd37 - 90x50mm (48 micron x/y)
Acer p1500 / h6510bd / viewsonic 7820 - 120x80mm (67 micron x/y)
