Elegoo Neptune 4 Max Cartographer/Beacon Mounting Bracket

I installed the original bracket on my Neptune 4 Pro, and really wanted to do the same on my Max, but the bracket didn't fit, so I made this one. It would still work on the Pro, not sure about other Neptune printers.

Thanks to Renzo van Vulpen for making the original design, and for the bulk of this description!

BoM:

• 2 M3 threaded inserts

• 2 short M3 screws (Make sure the head is small, DIN912 will not work. The cartographer probe included suitable ones)

• Cartographer or Beacon bed scanner

• One M3x5mm screw (the one the original bed probe was connected with was too long for me)

Disassembly of the toolhead:

I actually found an (in my opinion) easier way of removing the toolhead (worked on the Pro too)...

• Fully unscrew the belt tensioner screw on the x axis

• Disconnect the belt from the toolhead from the back

• Disconnect the cable from the top of the toolhead

• Loosen the top two rolling wheels on the toolhead, but don't fully take them off

  • On the Max, you need an 8mm socket and a hex wrench

  • On the Pro, you just need a hex wrench

• Now, you can just lift the toolhead off of the x axis

• Make sure to remove the auxiliary fan, or the bed scanner will hit it.

• Remove the toolhead cover.

• Remove the inductive probe from the toolhead (Detach the cable from the toolhead board also).

Install:

• Melt the 2 threaded inserts into the 2 bottom holes of the mounting bracket, these will be the mounting points for the bed scanner.

• Slide the mounting bracket on the toolhead from left to right (seem from the back of the toolhead) It will clip into the fan holes first, then slid to the right so the screw hole lines up.

• Use the screw from the original inductive probe to attach the bracket securely.

• Use 2 M3 screws to attach the bed scanner to the mounting bracket.

• Slide the toolhead back onto the X-axis and connect the cables to both the toolhead and the bed scanner.

• Tighten the rolling wheels on the back of the toolhead

• Attach the belts to the toolhead and put the belt tensioner back in place.

• You can route the cable the side of the toolhead as seen in one of the pictures, the route it through the strain relief bracket at the top of the toolhead to prevent stresses on the cable.

Printing

The print is optimized to be printed on this side without any supports:

I printed it in Prusament PC Blend, 4 perimeters, 40% infill and using a brim, and it's been working fine. The original creator used ABS and 100% infill.

Firmware install:

I'm using Opennept4une (https://github.com/OpenNeptune3D/OpenNept4une) and I recommend you do too.

• X-offset = 0mm

• Y-offset =  23,84mm

PS: Sorry for the bad photo, I have my N4M in a fairly inaccessible corner...
