Piezo Hotend z-probe for e3d v6 + Magnetic Delta P

Introduction
Here is the end result of a lot of hard work by a whole list of people: LeadingLights, DJDemonD, Moriquendi and Huntley. We just put the finishing touches to the design. So for the full description, check out DJDemonD's page.

This is an effector with an integrated calibration sensor. The effector is designed to use Huntley's magnetic joints. The calibration sensor is a peizoelectric sensor mounting on top of the hot end. It senses when the nozzle touches the print surface and this can be registered and used for calibrating the print bed.

Building it
Make sure the holes for the bolts and for the pins are sized correctly. the screws should pass though the holes freely, the pins should be press fit into the Mount base and slide in the Clamp.

Here is a list of all the needed nuts and bolts:
All nuts and bolts are M3 and it is best to use cap screws.

• 3 x 14 mm to fix base to effector
• 3 x 20 mm to mount clamp tight to base
• 2 x 20 mm to close the clamp on the hot end
• 10 nuts M3 (if also mounting the Nimble, otherwise 8 is enough)
  

Also needed are 3 pins of acetal or PTFE, 4 mm diameter x 16 mm long
You will probably need to widen the holes in the clamp for the pins. This will take a little bit of careful adjustments to get the pins sliding properly but not with too much play. As said before, make sure they fit tightly into the Mount base.

Using it with the Nimble
If fitting the Nimble. The 2 screws mounting the Nimble need to be modified, so they do not touch the peizo sensor when it is installed.

• 1 x 33 mm long,
  this screw needs to be shortened a bit from the standard 35 mm supplied with the Nimble
• 1 x 36 mm long,
  this screw needs to be shortened a bit from a standard 40 mm screw
  

The center hole is for the PTFE tube that reaches up to the Nimble so you can print using flexible filaments. Make sure the length is enough to reach above the top of the lock-in adapter bloc. After installing it, slice the PTFE tube flush with the block. Perfect length, life can be so simple.

If you are not using the Nimble (yet) you can enlarge the hole a little to make the bowden tube easier to slide through. But remember to print the Mount bases again if you are going to use the Nimble.


The Nimble Extruder
With an installed weight of less than 27 grams on your carriage/effector the Zesty Nimble is smallest and lightest extruder you can buy, it has ample torque and can be mounted in multiple orientations.

The Nimble is available from Zesty Technology.
