Hi!
I noticed this issue recently, and finally mapped why it happens.
If a print that is very high finishes, the bed is lowered all the way to the bottom when the job finishes, so far so good.
The problem is when I start the new print. When I start it, the printer tries to bring the bed further down, and starts to make an awful noise, that is the belt jumping on the stepper motor. This is destroying the belt!
If before starting a new print, I home the printer, this doesn’t happen anymore.
I initially thought it could be some sensor not working, but it’s not the case.
If I manually move the bed in the control screen, it stops in the bottom and doesn’t attempt to go further.
So this looks like some FW issue that in the beginning of the print doesn’t read the sensor and tries to move the bed beyond it’s limits.
Anyone else noticed this issue?
I’ve the latest FW installed (non beta).
Thanks.
