Simple Z axis homing


Recommended Posts

Posted · Simple Z axis homing

After spending a lot of time with the fussy z axis homing adjustment, I designed what I think is a simple and accurate way of doing this. <htttp://www.pbase.com/mark10970/ultimaker>

The main component is an inexpensive miniature brass fitting that has two 10-32 threaded holes and one male 10-32 . Here is an example:

As shown in the photos I used a 10-32 thumbscrew, a 10-32 nut to lock the thumbscrew and a piece of .032 inch (.8mm) copper clad board. The bracket for the switch is made from a piece of angle aluminum. The mechanism is below the build platform in an easy to access location.

I also added a hotbed with 3 point leveling. Leveling and homing are now simple. The single point is never adjusted. Simply use the other two leveling points to level the bed, then use the Z adjustment to home. Takes about 2 minutes for the whole thing.

The yellow zip tie seen in the last two photos holds the bowden tube in place. I doubt that it is a permanent cure, but it works for now while I investigate other options. Without it the tube slips horribly.

    I use this printable thing for the same effect: http://www.thingiverse.com/thing:11033

    Care to share your instructions? Am currently building one of my own and more examples never hurt :)

    I thought in the newer ulitmakers (V2 hot end) this was no longer a problem.

    It does, however, look like you have that ziptie just where the blue clip is supposed to be - is there a blue clip hidden underneath? If it were missing then slipping would certainly result.
