Several times when beginning a print, my Mini 2 does the X axis movement, moving the carriage to the left (the very first thing it does, before auto leveling, etc.), then grinds for a second or so, then puts up the message "Homing Failed: Please Reset". I noticed that this seems to more likely happen if the tool head is more to the left when beginning. I work around this by powering off and manually pushing the tool head to the right, then starting again, after which it works.
Is there a better way to address this problem? How does one "reset"? Is manually moving the head with the power off ill advised? Are there some x axis margins that need to be adjusted?
Homing Failed, Please Reset
Re: Homing Failed, Please Reset
It seems to be getting worse, as in it's happening more often. Now it sometimes gets past the initial homing, does the hot end cleaning on the pads, then when it tries to home again just after the head cleaning, it jams, grinds and then aborts the print. See attached video. Sounds horrible! Please help!

I just noticed something odd with the top of the tool head: a wire connector that seems to be at an odd angle. Maybe it's loose?
Re: Homing Failed, Please Reset
I called tech support, and D. H. gave me a simple fix: adjusting the bump stop for the x axis. It no longer grinds! Yes!

How do you adjust the bump stop? I am having the same issue and it’s getting worse. Thanks!
Re: Homing Failed, Please Reset
To adjust your bump stop you will just need to loosen the two small 1.5mm hex screws that hold it in place (don't completely remove them). Then with the screws loose grip the bump stop and pull it out towards the toolhead (to the right). Tighten the screws back into place while holding the bump stop in position.fitzfam2009 wrote: ↑Fri Nov 30, 2018 11:57 pmHow do you adjust the bump stop?

I've attached a photo of the bump stop to help you locate the correct area.
