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.

Like the great accessibility of your z-axis adjuster. Is there any loss of maximum vertical movement of the mounting plate?

No, there is no problem with the vertical limit. If there were, you could just extend the moving piece a little further down.

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

 

I also added a hotbed with 3 point leveling.

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.
