Bilinear bed leveling probes only 6 points instead of 9 #777

Hello,

When leveling the bed with BLtouch original using 4.4.0 firmware, it only probes the first 6 points and "forgets" the last 3 ones. It was working fine with 3.3.9 firmware. I've tried both manual leveling (via Nextion display) and auto before printing, same result.

Any idea why? thanks in advance

I answer to myself, it's working better with the last updated firmware, I have the 9 points probing except that the 7th one probing out of the bed without doing any modification. So I changed the distance between the bed edge and the Bltouch pin. Now the first 3 points on the x axis probe at 2.5cms and the last 3 points probe at 10 cms from the edge of the bed. It's not logical but at least it's working!
