Would this work? (8 replies)

I was having a think about CoreXY solutions and had a look at the X3D XS CoreXY which looked good but still has Z axis moving. I was wondering if I removed the stepper motors from the gantry with the CoreXY and had this sliding on rods (probably unconstrained at the top end) if I could not extend the idea to the Z axis as well. Obviously the rear two 'rods' would need to be able to turn the spindles on the gantry to be able to control the X and Y Axis so I would suggest a Triangular rod. This would then have to allow Z axis movement so I came up with a quick bearing support. I would implenment the gantry movement on the underside and alow gravity to hold them in place. As the gantry is suspended, unless it drops at a rate to allow the spindles to move up then this shouldn't be an issue.

What do you guys think? As I said, it was a quick lunchtime musing and I haven't worked out finer details; that is why the concept is hand drawn.

Cheers,
