The printer is showing the error "Check the heat block (black rectangle) on the tool for dirt or debris."
Error name: Hotend thermal runaway
Error code: #36204 (INDX)
The error will show if the temperature on the nozzle drops by 12 ºC for an extended period of time. This temperature drop would usually not be an issue, but if the heat is not recovered after 60 seconds, the error will happen. In this case, the printer will stop the heating and display the message on the screen.
Make sure that the ambient temperature where the printer is is stable and above 18 ºC.
Try parking the current nozzle and pick up another nozzle. See if the issue follows the print head to another nozzle, or if the error is only on one nozzle.
If the issue follows the print head, contact our Customer support.
If the issue is only in one nozzle, check the measuring pad to make sure it is clean and has no debris covering it.
On the xBuddy board, check if the fuse that protects the extruder is not damaged.
Check the connection of the head cable on the xBuddy board and extension board.
Locate the xBuddy board case. Looking at the printer from the rear, it is the rightmost case.
Using a T10 Torx key, remove six M3x4bT bolts to release the xBuddy box cover.
The bottom larger board is the xBuddy board, while the top smaller board is the xBuddy extension board.
