I could not sleep tonight so i made a little program! A simulation of a Stewart Platform (Hexapod)I wanted to see if you could make both the worktable and the spindle movable to get a bigger envelope on the same size of frame!
I made the model about 120cm (47 inch) diameter and about 90cm (35,5) high with:
X&Y - 80cm (31,5) and Z - 40cm (15,7) travel.
A&B - +/- 45 degrees tiltable.
The worktable is Indexable +/- 45 degrees too be able to machine at 90 degrees !The linear actuators would be about 30-35cm extendable to 60-70cm.
I have only programmed simulation for X,Y & Z yet. But you can try to index the spindle and then run the simulation, or try another g-code (just replace test.txt)
