My Lulzbot Mini has some calibrating issues. Because a video of the issue says more then hundred words I have made a video of it and upload it to youtube: https://youtu.be/3U8rit6hhyo
The calibration is in the middle of nowhere and not over the washer. Because the Mini does not get a feedback he starts the cleaning procedure and repeat from the start.
I do not understand, why he does not start with the normal cleaning procedure.
It uses the unmodified stock g-code of Cura LE… It shows the same movements after several reinstallations (yes, I deleted the cache before every new installation) and in the different software versions. I will post it this evening.
Ok,
It is solved since several weeks but maybe someone has the same issue.
With the help of Lulzbot Tech-support I checked the endstops with the M119 command. Although no endstop was triggered physically Cura showed that y_min was triggered. In this case no callibration is possible.
It seems that I caused a shortcut with the power supply of the heater and the hotend itself. This will damage the Rambo and it has to be replaced.
With a new Rambo everything works fine.
I hope this will help someone with the same problem.
