Hello All,I have progressed a little with the design and modeling of the machine I asked for help simulating. It has evolved a little over the last few weeks. have a look at the pdf attached for pictures Another month and I will be back to the world of fast Internet and I should be able to try some of the previous suggestions for simulation.
The big question is:Could linuxCNC something control this? or do I have 2 many variables with no fixed base position?
A few other questions and thoughts I would like to pick your collective brains on.
How would you home something like this?I stile haven't simulated the movement digitally yet or built a complete cardboard and drinking straw model, but i think i have finally settled on approximate geometry any questions or comments are gladly welcome. Has any one seen any thing like this before I am sure I am not the first? Is there any grate big flaw with this logic that I have missed?
Advantages: - Uses relatively short ball screws for the motion envelope achieved. - Commonality and limited part count- If I can build the arms as hollow weldments It should be possible to make the dynamic components very stiff and light allowing high speeds and acceleration. Still lots of work to do on this front. In the diagram attached things would bend like a wet noodle and I would soon get stress cracks.
- No spherical Joints (think it should work with out them not really sure) Thanks in advance, Linden PS The model is made with FreeCad
