Real world deflection - 1000mm

Post by Improbable Construct » Wed Jun 13, 2012 12:41 am

I got my heavily modified ShapeOko back together after lengthening the Y axis to 1000mm. I also doubled up the Makerslide on the X axis for stability.

I put a dial indicator near the center of the span. (50mm away from center)

I then ran the gantry to the center of the span.

The deflection measured about .0065 inch.
When I moved the indicator to center and moved the gantry as close to it as i could get, it measured .007 inch.
I couldn't get a good angle for a picture for this one. :(
That is with the DeWalt DW660 mounted on the Z axis
I think I can work with that.
In metal it might be a problem, but in wood, it is way better than most of the other tools I have.

Did you brace the Y with any extra footing/support? I assume your X length is original length?

The Y axis is not braced in any way. No footings or other supports. The X axis is the original length, but it is doubled up.

You doubled the x axis to strengthen it rotationaly so you could put guide wheels on both sides?
