Im interested in the e3d chimera printer head, it says it can adjust its heat break to level out nozzles of different sizes. However I want to attach a e3d valcano as one of the heads, which will mean the basic v6 head it comes with will need to be lowered significantly (about 10mm).

Is this to low for the grub screws to firmly grasp the heatbreak?

Has anyone already attempted this?
