@alxndr said in Duet 2 Wifi + BLtouch issues on Ender 5 pro:

But it only probes 3 while saying it can't reach some points.

Adjust your M557 grid based on your M208 size and your G31 probe offset.

If it's saying it can't reach a point, it's because it physically can't get the probe there. So move that point further in where the probe can reach.
