Description
Centauri Carbon 2 Strain Gauge PCB 50.204.0304
While the individual strain gauge sensors (the tiny pressure pads) are located under the heated bed, this specific PCB acts as the central hub that collects their signals and converts them into data the mainboard can understand.
How It Works
The Centauri Carbon uses a "nozzle-touch" leveling system. When the nozzle taps the build plate, the pressure is measured by four strain gauges located at the corners of the bed assembly.
Signal Conversion: This board (50.204.0304) takes the tiny analog voltage changes from those sensors and processes them.
Auto-Leveling: It enables the printer to map a precise 121-point (11x11) grid of the bed's surface.
Z-Offset: It allows the machine to calculate the exact distance between the nozzle and the bed without manual user intervention.
Common Failure Symptoms
If this board or the connected sensors are failing, you will likely see:
"Nozzle Divenose": The nozzle hits the bed and keeps pushing down because it never "felt" the touch.
Error 502: "Leveling sensor data collection error."
Inconsistent Z-Offset: Your first layer is perfect on one side but 3mm in the air on the other.
Maintenance Tip
If your bed leveling is failing, check the rubber nozzle wiper brush first. On the Centauri Carbon, if that brush is pushed too far forward or is loose, the bed can hit it during the homing process. The strain gauges will detect that "tap" on the brush instead of the bed, leading to a massive Z-offset error.
