Hello Haydn,
Could you tell me what the diamond shape piece with three hols is for in the J-Head effector design and where do you mount the Z-probe on the j-head effector.


Hey! I made a different cooling solution for your effector that you might find interesting using an overhung blower to maximize build volume. Check it out over at if you have a moment. Thanks for making a great magnetic effector and rod solution!

Thank you for the information. I really appreciate it. I received a set of your rods in the mail yesterday. They look great!
