NOTE: The pin on my BIQU Microprobe unscrewed itself after several prints - probably due to vibration. The pin can be unscrewed (see photo) and some loctite applied to the threads before screwing it back in. I've tested this a while now and it fixes the issue.

V20: For use with stock Sovol SV08 nozzles.
V21: For use with Sovol ‘hardened nozzle’ adapter and Neptune 4 Max nozzles. Note: The hot end carriage is very close to the bed when using these nozzles. Check your clearance.

This model would not exist without https://www.printables.com/model/947550-sovol-sv08-microprobe-mount - Read the instructions for connecting and configuring the probe there. The only difference in configuration for this mount is, in microprobe.cfg:

x_offset: -18.55
y_offset: 10.5

Also, in printer.cfg under [bed_mesh], set:

mesh_min: 5,15
mesh_max: 325,345

…to account for the new probe offsets.

The model is not a remix, but a complete new version that mounts the probe ‘backwards’ which I believe could give the mount a bit more stability? This mount uses the rear fan screw holes instead of using the print head mounting plate screws. 

Is it better? I don't know, but I wanted to try :)

Printing instructions:

  • Forget PLA. It may survive one print (which it did in testing, but after the print, it was soft and squishy).
  • Tested PC. At least my (cheap) roll of PC showed some creep when tightened for a couple of days, so I can't recommend that type of filament.
  • ABS, ASA - Tested and works! ASA tested more than ABS, currently.
  • Print with 45% infill, 0.12 mm layer height and 5 walls. This makes the part rigid.

To mount, you need: 

  • 2 pcs M2.5 screws (included with the BIQU probe)
  • 2 pcs M2.5 nuts (also included with the BIQU probe)
  • 2 pcs M3x20 (same kind of head as the BIQU screws - round hex head)
  • 2 pcs M3 nuts

Steps:

  • Mount the probe to the mount with the 2 M2.5 screws and 2 nuts. Apply threadlock (loctite)!.
  • Connect the cable (Make sure to follow the instructions in the model mentioned above to make the cable.)
  • Unscrew fan screws from the back (really short M3 bolts)
  • Remove hot end including heat break (2 screws top left, 1 screw middle front)
  • Fasten the mount by screwing the 2 M3x20 bolts from the front. Apply threadlock (loctite)!
  • Put the rear fan back on the now protruding M3x20 bolts.
  • Add a nut on each bolt. Apply threadlock (loctite)! Note: When tightening the nuts, apply some torque to the front bolts so they don't unscrew.
  • Remount the heat break with the 3 screws.
  • Remount the shroud - It may take some wiggling to seat properly, but it fits!
  • Done.
  • Run PROBE_CALIBRATE to calibrate your new probe mounting position :)
