Is this an example of what backlash can do?

And yes... it's the worst example of a sphere I've ever seen.... mind you it's first attempt at anything on the mill.....

all part and parcel of building a cnc in my opinion, i think we have all had our share of disasters but yours has really tickled me, i actualy laughed out loud when i saw that picture.... it reminds me that im not alone on the planet

it looks like it will be a pretty simple fix with a bit of messing about in motor tuning

let us know if you manage to carve anymore square spheres :)
