Good day, this base is made for sensor sonic pad because install mod of taurus v4 with fans 5015 with them the space reduce and base put lateral right of the head extruder.

The space for the sensor is tight so that it does not move during the tests. I recommend using an Allen wrench to pull the sensor from the base. In my case, I leave it on since it does not stick to the right bar of the device.

Sorry for the grammathical errors, english is not a native language.
