Cartographer Mount for Neptune 3 Pro/Plus/Max (Volcano Heatblock)

UPDATE: (v1-2, 1 mar 2026)

added a cutout for the heater housing on the printhead pcb:

BOM:

• 2xM2 bolt 6mm

• 2xM2 nut

• 2xM3 bolt 4 or 6mm

• 3xZip Tie 2mm width

Description:

I made this mount for easy printhead removal, allowing the cartographer to remain on the carriage.

This mount is easier to install with the carriage removed from the x-axis, but if you are too lazy (like me), I've made a positioning tool for the nut. 

Probe offset:

x_offset: 0                          
y_offset: 30

Print recommendations:

• 0.2 layer height, 0.4 layer width

• No supports

• 3 wall loops

• 4.2mm bottom shell thickness

Measuring Resonances:

It doesn't work perfectly for input shaping calibration. I recommend cutting the graph at 75Hz to get a correct shaper recommendation

Correct measurements:
