Low Cost Hobby Servo XY Table

Step 5 Clamp the Timing Belts to the Stages

To attach the X stage, we used an aluminum plate (about 1"x3") under the Y stage board with two screws on each side of the timing belt. We drilled two holes in the X stage to get our 3" driver bit in there - put in two screws, then slide the assembly up a bit and add two more screws. For the Y stage, we made two aluminum plates (one about 1"x3", and the other about 1"x1") to connect the belt to the stage. In each case, you are just trying to clamp (or pinch) the belt to the mechanism.

if i were going to use roller-chain-sprockets instead of timing belt, is that possible to clamp the chain like what you've done here?

[CarlS]

Maybe you could even just put a screw through one of the links?  We could have done that with the timing belts too, but we were reluctant to put a hole in the timing belt.

another question here. in this step 5 (picture number 2), does the small wood block, which attach on the Y-axis top glide, glue/screw together with the X-axis ?

[CarlS]

Yes, I think its described in Step 4 - we attached small blocks to the X Axis glides, then the Y axis board to the tops of those blocks.  That was so the Y Axis was above the X Axis timing belt.
