I try to make circuit board with SMD IC with Snapmaker 2.0. However, I think the positional accuracy of the Z axis is insufficient. Since the XY table is fixed at the two central points, the table swings in the direction of the arrow. The width of the copper foil to be machined has a strong influ…

Thank you for your reply. After all, as with 3D printing, some kind of Z-axis correction function needs to be added.

Such a function should never be the default. If want to mill a piece of stock flat, there is no use for such a function. And in most cases, that’s exactly what you would do. Even if your stock isn’t flat, for most use cases, you’ll first make it flat. There are very specific scenario’s where it’s n…

I send @brvdboss ’s recommendation to mill the wasteboard flat, after tramming to a repeatable reference (not the surface of the wasteboard, although it could work). I’m not a fan of using the endstops at the top of the z modules because they are not engineered to precisely be level with the surface…

As someone who hates a poor work surface this seems like a grand idea. I would be willing to mill the wasteboard flat, but my eye would be twitching the whole time.

The precision with which the PWB is machined by CNC is not high
