Hello everyone, I made a small modification to my Snapmaker 2.0 to be able to automatically level on a glass plate. It´s a simple holder for a 12mm capacitive proximity switch as a Z probe. If you use a NPN normally open NO proximity switch 24V, you can use it without firmware modifications. Eve…

That’s what I have, the v2 of the 2.0 print head. Let us know how it goes!

Here is the comparison between a 5x5 manual level, and a 5x5 auto level using the capacitance sensor, both on a glass bed. The manual calibration shows my bed level delta as 0.150, while the auto level shows 0.175. This overall difference of 0.025 and the greatest single-point difference of 0.035 i…

Thought I’d post it here for historical value - Beacon Probe Review and tutorial - YouTube

Unfortunately that video is not of much use since it does not apply to the Snapmaker or its Marlin firmware.

Hi, Very clever project. Do you have a step by step how to process or it's straitgh forward installation without any mod on firmware or something else to do? Thank you!

Thanks. The process is very self explaining. Take cake of buying the exact right proximity switch type and wiring it like the original one. (Matching color’s of the wires.) Print and mount the part. (You eventually need to adjust the proximity switch itself on the approximate distance to the gl…

Thanks! I’ll give it a try soon! Cheers!

Hi, I got my sensor ( Capacitive Proximity Sensor Switch LJC12A3-5-Z/BX ) and made the mod... But, when I tried to level, the nozzle hit the glass and push it down... I’m using GO 3D Borosilicate glass. My sensor is 1mm above the nozzle and I’m using print head V1. What I should do to make it w…

Did you adjust your sensor with the adjustment screw beforehand? Hold a piece of plastic or glass under the sensor and check when the sensor turns red. When the sensor lights up, adjust the position so that the trigger area is lower than the nozzle. Test it all in the air (Z 100+) so you don’t cr…
