Genuine Sovol filament sensor is causing lots of friction. Actually so much that in some cases the print quality is seriously affected (printed layers are not consistent). This happens due to faulty design of the sensor itself and also wrong positioning on a SV06 frame, relative to filament spool width:

  1. filament is straighten-up in the sensor, with no proper friction relief
  2. the sensor is not in the middle of the filament spool (please check this mod for a solution – https://www.printables.com/model/487507-mak-sovol-sv06-sensor-arm-mod)

Both issues are causing an additional, not necessary friction. 

This modification is addressing the first issue.

The mod has much less friction, as it uses PTFE tube to guide the filament into the sensor and allow to have more space after triggering the switch inside. I have no way to measure it objectively, but finger feel difference is HUGE.

On the attached pictures the mod is orange, the genuine Sovol sensor is black.

Printing and Assembly

Printing is straight forward, with no supports needed (when properly rotated on the bed).

Disassembly of the genuine Sovol sensor is simple and reversible. Just unscrew two bolts from the metal plate and take the genuine case and the cover apart (they are not glued, just stick tightly together, shown on one of the attached pictures). Then take the electronics out, put it in the modded casing and mount everything back in place.

14-15mm PTFE tube of popular 4/2mm size is required to be fitted into place, as shown on the attached pictures. It should fit tightly, with no glue needed (PTFE is very difficult to glue anyways).

That is all, ENJOY! :-)
