[image] How to adjust the probe/proximity sensor in the 3D printing module? First, you can update the software and the firmware via the following links:https://forum.snapmaker.com/t/snapmaker-luban-downloads-and-updates/4949/11 https://forum.snapmaker.com/t/snapmaker-2-0-f... …

This is what I posted before I saw that they had posted a similar set of instructions: I posted this in the thread about the module digging into the build plate, but this is also how I finally got my bed level issues worked out, and started getting practically perfect first layers without any hassl…

Hi, our technical support has revised the description since your feedback. Please check to see if it makes sense now. :sweat_smile:

@JKC20 I used @Kerrida instructions, but yes, this does look better. Worth noting that I don’t think I’ve ever seen the “red dot”

The red dot appears on the the sensor. I usually watch for it from the right hand side of the machine.

Two things here I’m not conscious about. do I have to adjust the sensor in every case, I mean also if the autoleveling is working? I don’t understand the sentence “I am afraid that you may need to adjust the proximity sensor before you use it.” -in the guide from @kerrida the printer has to be of…

As my guide has you move the module to where it is only held on by two screws it ends up being well below where the machine expects it. You could use the controls to lower the axis down, but it’s too risky IMO. You can safely lower it manually with the machine powered off while making this adjustmen…

[image] Kerrida: is what I posted before I saw that they had posted a similar set The guide shows what looks like a calibration tool under the sensor and nozzle. Where can I get this?

I hadn’t noticed that until you pointed it out. It looks like a piece of plastic with one end milled down, presumably by 1mm. The exact height difference in their gauge would be good to know, for those of us with the capacity to make one. And yes, it should be included in that snazzy toolkit that …

I agree that it would be awesome to have one included or provide an stl for us to mill or print one. I have had my SM A350 for 4 months and have not been able to get a print out and I am getting really frustrated with this crazy calibration stuff.

Sorry for the late reply. [image] Here is the STL file. 2.STL (22.0 KB)

When the probe sensor is close to the print sheet or metal board, the red light will turn up.
