Proxxon MF70 conversion
Sorry, but i have made a few pictures.
This is the Y ax. I made all the distance blocks ( blocks between stepper and machine ) off aluminium 100mm X 60mm X4mm.
The 4 centers in square are for the steppers, The centers at the edge of the circle are for the mount of the block on the machine.
The circle is a hole for the stepper.
As you can see , there is on the stepper also a circle.
On a drilling machine drill the holes through the material and make a center at the bottom. then take a smaller drill and drill the small holes.
Cut the block to the right length and mount them on the machine.
For the X ax i have take a new piece of leadscrew. You can take also the original leadscrew.
This is the Z ax. I have made this block 56mm width and i make also 2 little caps in the block for the screws.
