Broke My Axe

The HB2 broke a coupling on the Y axis again. The couplings have been fine for 6 months. Must be more loads on it than I thought, but it is the axis with the dual steppers. It should have ½ the loads. The X and Z axis have never been a problem.

I thought it was most likely an alignment problem causing the couplings to flex too much. I was very particular in checking the alignment in the last replacement.

This time I am ordering extra heavy couplings from PDJ. They are the same style and exact size as I have been using but are built much stronger. They are a bit less expensive too, probably because Phil buys them in greater volume.

The failure spoiled a project I was cutting. Always happens near the end don’t you just know… I am glad it was a concept part and not some valuable slab of rare wood.
