Re: New Own Design Printer 'Cherry Pi'
It'd be easier for people to find the sketchup files if you add them on thingiverse instead of the github repo. .. and I can't find them on github site either..

The sketchup files are in the repo on GitHub called github. The description says sketchup design files. You should be able to get them easily! I will move them to Thingiverse if others have issues....

instead of perfectly straight threaded rod, i think it would be helpful to have smooth rod to guide the movement of each arm and threaded rod to drive the movement, as seen on the prusa i3. this way,...

@badetise: There are a few issues to work out with your suggestion. First, you need the pitch of your screw to be 10mm or more so the speed isn't painfully slow. Second, the shoulder pivots on the rod...

Even with some big motors and drivers, I suspect that I will have some speed limits on a 1/2" (12.5 mm) pitch screw. That's with a direct drive setup. I can live with the speed I'll (hopefully) get. I...

First post here. This is all very exciting! I was going to purchase a RockStock Max, but I think that I will go with the LISA now. I probably will try to build the bigger version, about 20" diameter...

@CTF, What one do you mean? 20" diameter print envelope. 25" tall print envelope. or 20" diameter machine outside dimensions. 25" tall machine outside dimensions. Presently I'm contemplating a 3X...

Effectively yes, like in the link. Just something soft to go around the hard bearings and soften the ride a bit.

Has a 5 axis robotic arm been considered? Belts, string and printable gears come to mind. A regular mendel 90 with a rotating bed is probably most straight forward.

@A2, I have no particular need for a specific size, I would like to build something simply a bit bigger than the original Lisa. :) I think that the 20" diameter print envelope, 25" tall print envelope...

I know this is my design but I feel the need to reiterate that there are a lot of thing that could go wrong with a bigger design. Things don't always scale like you would hope them too. If you have a...

I am not sure what exactly the min xy resolution of LISA is but for my 1/32 microstepping with 1" pitch screws the z resolution is 4 microns. Relying on microstepping is a bit of a cheat but I am sure...

Quotenicholas.sewardIf I get around to building a bigger LISA and leveling is an issue I may try to put it back in. Maybe we should build one for you to experiment with. :)

@CTF: I wish it could work that way. :-) I have a big printer in my future. I just don't know what it is going to be. I think LISA is a good candidate for a medium sized printer but for a truly large...
