The Original Prusa printers are equipped with a Power Panic feature. This feature can recover a print in case of a sudden power loss (read more about it here). The power panic cable goes from the printer's PSU to the xBuddy board. If the cable is damaged, the printer will show "Power panic has been detected during printer initialization. Inspect wiring of PP-cable".
Error name: Power Panic
Error code: #36321 (INDX) #31321 (CORE One) #35321 (CORE One L) #26321 (MK4S) #13321 (MK4) #27321 (MK3.9S) #21321 (MK3.9) #28321 (MK3.5S) #23321 (MK3.5)
Check the cable connection on the PSU and on the xBuddy board. Make sure that the cable is not damaged.
Note: on CORE One, MK4/S, MK3.9/S, and MK3.5/S, there are two versions of the power panic cable, one with only a black wire and one with black and white wires. Both are compatible with these printer models, and there is no need to switch to one or the other. This note does not apply to CORE One L.
On CORE One L, access the electronics, and locate the power panic cable in the bundle of PSU power cables, to inspect it for any damage.
Do not hesitate to contact our 24/7 technical support in all scenarios. We can guide you through the electronics and cables while you are inspecting them, and provide help if replacement components are needed.
