SOVOL SV08 M12 Inductive Probe Mount LJ12A3-4-Z/AX

…Please be sure to hit like & post a make, I'd love to see your prints!
 

Add a highly accurate M12 LJ12A3-4-Z/AX inductive probe to your SV08! 
 

This probe is a NPN NC probe. This means it is normally closed & will provide a “low” signal when triggered, so you’ll see voltage when un-triggered that’ll swing to ground (0v) once triggered. 
 

Some stock probes seem to have a tolerance range that’s slightly below optimal, this probe has been proven to be far more accurate in many applications.

These are my PROBE_ACCURACY results:

The stock probe cannot get these results!

PRINT IN ASA OR ABS!!! or better. 

Orientate on flat end, standing upright, use tree supports.

NOTE: Grey PLA test print in photos above, dont print in PLA!

NOTE: The SV08 Supplies 24v to the probe!! Make sure your probe is 24v rated.

NEW PROBE OFFSET: X-16.8 Y8.7

IMPROVE YOUR PROBING & MESHING!!

Amend your stock settings with these values, they're not complete sections in some cases so DO NOT just copy/paste over the top of your current sections! Double check the values & don't delete anything you shouldn't!

YOU WILL NEED…

x1 M3 16mm toolhead mounting bolt (left). 

x1 M3 6-8mm button head bolt (inside) 

IMPORTANT NOTE: the head on this bolt must be less than 1.5mm tall or the probe WONT FIT!!

x1 M3 VORON BOM heat insert

x1 M3 cap or button head 6-8mm bolt

THREADLOCK!!!

You must threadlock the bolts in place. 
 

INSTALL... 

Drop the M3 button head bolt into internal hole & pass a hex key through the M3 heat insert to access the bolt. Offer & locate to the toolhead & tighten making sure the external hole lines up with the toolhead mounting bolt. 

 

Add longer toolhead mounting bolt to secure. 
 

Pass probe cables through the mount from the bottom.

Followed by the probe…

Align the probe level with the base of the toolhead bracket…

Add the retaining bolt & secure with THREADLOCK!

Make sure the top of the probe is NOT touching the extruder base.
