Because of the way that the original router mount was designed, I lost a lot of usable router bit length. So I redesigned it immediately; it was the first real job I ran on the CNC machine.
But, because the new mount effectively shifted the router downward by about 3″, I lost a lot of router travel, because in order to clear the workpiece, I had to raise the Z-axis almost all the way to the top.
The mount needed shifting to compensate, but, with one thing and another, I’d never gotten around to it.
I finally decided to take care of that yesterday, with nice results:
As you can see, all it took was drilling a couple of new holes a bit higher up on the Z-axis sides. It’s hard to see in the photo, but the collet still sits below the Z-axis side, so it’s easy to change bits.
All of a sudden, I have about 4″ of travel in the Z axis! nice!
