I just inherited an original LulzBot Mini - installed Cura LE, did a firmware update because USB connectivity was flaky before that, and reset the factory Z-offset.
Right now I am failing to print because the printer is failing to do bed levelling. The problem is that the head is not going low enough to actually touch the washers. Similarly, if I move the head to Z-home manually, I cannot manually lower the head enough to actually make contact with the washers. However if I disconnect and reconnect with the head already mostly down, I am able to move the head low enough to make contact. Does anyone have suggestions for what to try next - it seems like the Z range isn’t large enough.
