Hi Ryan LB, the bolts are 1/4-20 x 1.5 inch. For the collet I use one of these two wrenches, based on another one I found on thingiverse. I do usually have to remove the dust shoe to change the bits, especially if I have the change the collet too. There are techniques that make that task – not simple, but simpler. Locking the steppers helps. A pause script can move everything into the best position for changing bits. You can use a regular wrench on the collet, but these are easy to handle, and one of them has a thing that holds the bit up – useful when you’re trying to change out a 15 degree v tip.
