I was looking for a second hand sonic pad in order to add wifi functionality to my ender 3 V2 that I am pretty happy with. I also expected some speed improvement but that was not the key reason that I wanted one. The wifi feature was the main reason

I found this deal from someone who was selling one along with a laser module (its the small 1.6 watt and an ender 3 s1 (not sure which one). All of that for what corresponds to $150

At some point I thought I had been scammed because it took quite some time before I received the package, but it is all here and I am stocked. I am not even sure what I've bought but it feels like a deal. Especially because in my country we have 25% VAT and fairly high prices.

Edit: It is an s1 pro!

On YT, CHEP is probably one of the best references for basic Ender setup and use.

You are unlikely to have the issue overall, but there is a nonzero chance of having issues with any aluminum extrusions based linear motion system. It is only a serious problem for a single digits percentage of people and the problem is worse on larger printers.

When aluminum extrusions are manufactured, the tolerances of faces are really good. However the one factor that is poorly constrained is twist. The amount is imperceptible without a metrology setup to measure the deviation. In the unlikely chance that you have triple checked every part of your setup, and you are still having issues, keep in mind this is a thing that exists. Try swapping symmetrical components where possible to see if the problem follows the swapped extrusion. This is one of those issues that is nearly impossible to find on your own unless you know to look for it.

If you need any help, don't hesitate to reach out directly, or post. I'll help you any way I can. Happy printing!

Thanks! I was especially concerned to have a private seller ship the printer, but when they told me that they had the original box I felt pretty safe that it would be ok.

I'll keep an eye out for flaws thanks
