Another failure...

---

This morning I changed slightly the cutting parameters of the final cut hoping that this will help. I also gave up on using WD-40 hoping that this will avoid jamming the wheels of the Y carriage. I was wrong...

The Y axis keeps jamming. The aluminium chips gets stuck on the linear rails and the wheels adding some unneeded friction in the Y movements.

But hey, I'm a hacker. Let's hack this little beast and see what happens.

Some double-sided tape and cardboard later, here's some nice debris shields for the linear rails. These don't need to be sturdy so cardboard is an excellent choice.

.. and here's the machine ready for another attempt.

Wish me luck!
