Maslow user @Dag83 created a thorough explanation on how to install the z-axis motor and modify a Bosch POF 1200 (or POF 1400) to fit in the ring.

Progress so far…
Now add the 3d printed part from the bosch kit
Now the nut
Now add the 4 screws. It might help to pre-drill these a bit with a very small drill. Don’t overtighten !!
Remark: in some cases the nut pops out when using the z-axis. Best to fix it to the shaft using small screws. Don’t drill through the cap and be sure to not clutch the shaft.
Drill a hole the power cord can go trough
Time to start rebuilding everything in the opposite order, you’ll figure it out
Connect the power cord, polarity doesn’t matter.
Refit the motor brushes, carefully, if you chip them, they’ll still work, but wear out much faster. and you’ll allready be abusing the router way more then it was designed for.
Find a nice spot to place the power connector, make sure that hole stays clear for the acme screw to pass later.
Refit the cover. It is a good idea to put a ty-rap around the cable on the inside so that the cable doesn’t come out when it gets pulled.
Time to find your hacksaw and cut off another piece.
Voila
Now to assemble the top mount.
First mount the motor on the plate with the screws provided in the Maslow box
Next install all the parts as shown in the photo. A bit of glue between the parts won’t hurt, the part gets a lot of tortion, and might require retightening later on.
Make sure the coupler is just barely touching the plate on the side of the acme screw, that way you’re not puling apart your coupler.
Now just screw the top part into the router, connect to groundcontrol so you can raise and lower it, and start making beautiful things.
Now all that’s left is changing the pitch in the settings of groundcontrol from -3.17 to -8 and you should be done.
