Z-Homing "Collision Detected" and failure
Hi, I assembled my new Core ONE + a week or so ago. I've been printing daily since then.
On almost every print, the homing process fails several times for seemingly no reason before succeeding.
X/Y homing taps alternating the front and right side about 4 times on each (f, r, f, r, f, r, f, r) and then it begins the z-homing process, which is where it fails. At first I thought it was due to a tiny bit of filament being deposited and then the load cell detecting that, due to the nozzle being heated up before the print begins. But even when I can see that the bed is clean, and the nozzle is, the homing still fails.
Usually it fails once, succeeds on the second try, and then starts printing. But today it has been failing three times, asking if I want to retry, and then working fine on the second or third retry with no changes within the printer. Each time it fails it says "collision detected" when most assuredly nothing is colliding.
Additionally, the printer probes and then prints beautifully, with no issues, for many hours. But the first layer is consistently .050mm too low every time. It prints fine but the first layer is trash unless I use the z-adjust to move it up .05mm at the start of each print.
I am assuming this is because the load-cell is way too sensitive, (seemingly even being triggered inches from the bed by "hair-thin" strands of filament) but I have no idea. People on reddit/this forum have said it might be the belts are too tight. As far as I know, the belts are properly tensioned, and I don't see how they would be related to z-homing?
Thank you.
