Hello, excuse my English, i am going to try to be understandable. I finish build my Snap A350, i triple checked and everything is at the right place well montés. When i try to do calibration, the x axe start Shaking, especially on the left. So far i cannot go further, i am blocked. I took a video but i don t see how to attach it here. Thank you very much if you have the answer of my problem… ---

You could upload your video to the forum or link it here, it doesn´t work to upload anything at your first post, but now it should work, i guess. Welcome! Post your video please 😉 ---

Mine does something similar. When then head moves to the far left (Home) of the X-axe it doesn’t stop trying to go more left and makes a lot of noise. Eventually it stops and the calibration starts. The first time I was worried because it sounded abnormal but since it continues normally after that but crashes in the print bed afterwards I tought if was normal. Can someone else aknowledge this is normal behaviour? ---

That behavior is NOT normal and you should email Snapmaker support. My guess is a fault in the limit switch or it simply fell off of it’s mounting inside the linear module. ---

Ok, mine is ok now. I opened the left side of the X-axis to test the switch and it worked. When I closed it it continued to work. @schneidereman As I can see from the video I think you inversed 2 AXIS on the splitters. Because it want to move in 2 directions but only on 1 of the 2 motors. Check your cabling. ---
