Hi Sabastian - Since your going to mainly cut foam I suggest you use a conventional long z axis, not the lifting gantry. I suggest that you design the spindle so it can be canted 45deg or even to horizontal. This means you can machine the left hand side with the tool leaned, this overcomes the collision angle issue. Then you manually cant to the other side and machine the right hand side. I did this on my first machine and it worked very well... You should consider a rotary platter and then you have a very good solution for this sort of task. The platter can be simply manually registered to four quadrants or can be under rotary axis control.. Peter

Hi Peter, yes I am going with a long Z axis now (something like 250mm / 300mm if i find a way that I feel comfortable with it). And again great input with the rotary platter, have to do a deep dive but I like it (gives me more possibilities in the foam than I was thinking about). I´m now going to make different design´s (gantry, vertical gantry support and z axis all steel and UHPC) hoping my specs are duable now. Run FEM to confirm what is the best direction for me to go.

I will post the different concepts here bevor I´ll go to the FEM simulation (static).

Thanks Peter!
