Print Stops Halfway Through

There are a number of reasons your prints may be stopping part way through. This guide will go through the causes and solutions.

1. Minimum Requirements Not Met​

Please check the following:

  • Raspberry Pi power supply is rated for at least 3 amps.
  • SD card in your Pi / Hub is at least 16GB, and rated as 'Class 10'.
  • SD card is from a reliable brand. Sandisk is the only brand we recommend using.
  • Non-Bambu printers are running on latest version of Marlin 2 firmware.

2. Power Supply Is Unstable​

Ensure your Raspberry Pi / Print Farm Hub is plugged into a power outlet with a stable power supply.

If you're running a high-power appliance on the same circuit (e.g. refrigerator, AC, toaster, kettle, microwave, multiple 3D printers heating up at the same time) this can cause a momentary dip in power, which can interrupt the power to the Raspberry Pi or Print Farm Hub, causing instability issues.

3. System Needs to be Reset​

"Just turn it off and on again". Believe it or not, this can solve stability issues like this in some cases.

Try rebooting your Pi / Print Farm Hub.

4. Corrupted SD Card​

Try re-flashing AutoFarm3D on your SD card. If the issue persists, try a new SD card (16 GB, Class 10, Reliable brand).

5. USB Connection Broken (Non-Bambu only)​

Broken USB cables can cause instability. Try connecting a new USB cable from your Pi/Hub to your printer.

If this doesn't fix the issue, it's possible the USB port on your 3D printer might be broken / loose. You may need a new motherboard.

6. Firmware Needs to be Reflashed​

Your printer firmware occasionally sends malformed responses to gcode commands. This is usually fixed by reflashing firmware.
