Hi everyone

After I had upgraded my K1C with the CFS system, not long after the 2 screw holes, where you mount the Hopper fixed Block to, broke.

so i made this z-axis top replacement mount, for the K1 and K1C.

It takes a bit of work to install it.

Take off the back plate and cut the old mount off, I used a Dremel Rotary Tool to remove it.

Don't cut the back off the top mount, only the 2 sides and the bottom.

File the 2 sides down and the bottom after you cut the mount off, so that the back where the mount was, is nice and flat.

Then mount the new Z top mount.

Press it down firmly, and screw in the rear top screw, (Countersunk screw M4x35) don't over tighten.

Take a 4 mm drill bit, and drill thrue the 2 front holes and thrue the back plate.

Put the 2 screws in (Countersunk screw M4x30), and a lock nut on the end of them, don't over tighten them.

Place the wires down in to the groove on the Z mount.

place the bearing in the hole where the Z-axis is, and mount the Hopper Fixed Block.

Put the back plate back on.

Remember to do a new calibration off the purge location.

If you decide to change the top Z-axis mount again, you don't need to remove the back plate again to do so.

I've been using it for about 4 months and it's worked fine, but Install part at your own risk.

I spent a lot of time making it, hope you like it :)
