What happened?

During calibration, mesh bed leveling, or before a print, it is crucial for the printer firmware to determine the print head and heatbed position. This is done through the homing process, where the print axes move to a known reference position, called home.

A MINI/+ printer in the home position will have the heatbed almost completely moved to the rear, and the print head completely moved right and down. 

For the Z axis, two homing attempts are performed. The MINI/+ firmware uses the MINDA/SuperPINDA probe readings of their distance to the steel sheet: the homing process passes if the two readings are within +- 0.1mm. If not, the printer will show the message "Homing Error". 

Error name: Homing Error

Error code: #12301

How to fix it?

The error might indicate an issue with the MINDA/SuperPINDA probe. Its cable can be damaged or disconnected. 

A visual inspection

Before further testing, you should check that the MINDA/SuperPINDA probe wires are not visibly broken. Also, make sure everything is connected to the Buddy mainboard, inside its case. Loosen the screw securing the cover (circled in the picture below), remove the top cable cover and flip it open to reveal the board.

 

Check that all the connectors are secure in their sockets, according to the picture below. Focus on the MINDA/SuperPINDA (yellow arrow). Though unlikely, rough shipping or handling could have shaken the MINDA/SuperPINDA cables loose.

Testing the MINDA/SuperPINDA probe

Follow the steps in the following article: M.I.N.D.A./SuperPINDA sensor testing (MINI/MINI+).

In case none of these tests are conclusive, do not hesitate to contact our Customer Support for further assistance.
