Hi all,
To start, I built myself a standard Prusa 1/2 year ago and I loved it, it's been working like a champ ever since. Now I am planning to build a larger printer based on the fact that I print architectural models and the height that Prusa can achieve does not satisfy my need. also I would like to design my own furniture and print objects much larger (well.. not as big as a table!)
I am planning to build one that can print around 300mm x 300mm x 300mm model, here are a few questions hope all experts here can help...
1. For the frame, should I use the Prusa setup or the Darwin setup?
2. Should the bed only moves in Z axis and use a standard CNC table setting for the X & Y axes?
3. Is using extruded aluminium, linear tracks and GT2 belts and ball screws the most sensible option to get high precision? Or am I just splashing money unnecessarily?
4. Is it right to use Bowden tube instead?
5. What is the best way to ensure the print bed is completely flat? I noticed that even glass can bend to some degree, so if the bed is 300mm x 300mm I think it is very difficult to calibrate the z axis.
also.. can you suggest and practical issues with printer at this size? eg.. file too heavy for the software to handle?.. etc..
many thanks
Adrian
