My A30m z axis only drops from the left side when I shut it down. I have a motor on each side for the z axis rods. But only the left side motor drops after it shuts off. Also if I don’t use the printer for like a minute it the left z axis motors drops by it self a little.
When I start to print again or level it. It goes to level it’s self and needs to recalibrate both z axis and i can tell the left side hits first by a lot.
How can I fix this ?

Hi,if you have 3d touch installed, you can try to calibrate it.

I had one but it broke somehow when my was printing.
I am about to order one right now.
But still why does the left side z axis drops when I shut down the printer ?
Or sometimes if I don’t do nothing it will just drop a little bit.
Just one side does it. It’s weird

Hi,You can check if the z-axis is loose.

The z axis is tight and it’s the motor it self. The left motor turning a little bit while it shuts off.
Should I just flash the software ??
