Finding the Right Firmware

For BMG Extruders:

Firmware above 1.0.29 will autodetect all parameters so there is no need to find a specific file. Just ensure that it matches your printer (IE. D3, H2, D6)

For Regular Extruders:

Firmware version will be between 1.0.0 and 1.0.26 <- being the latest.

Firmware is seperated by four parameters:

  • Powersupply
  • LCD manufacturer (TJC OR DWN)
  • Y Axis Switch Type (Mechanical or Optical)
  • Stepper motor driver type (4988 or 2208/2209)

FAQ

Cannot Open Port

1. This is typically caused by choosing the wrong COM-port or a faulty USB cable.

Verify your computer detects your printer:

1. Press the Windows Key.
2. Type Device Manager.
3. Navigate to USB Serial Devices.
4. Make sure the printer shows up, you can unplug and replug the connection to see any change in devices.

2. After downloading CH340 Drivers and installing, be sure to restart your PC.

Upload Failed?

1. Sometimes Xloader will say upload failed but actually succesfully upload. Verify by going to your printer menu, settings, then checking the firmware version.

2. Another cause of this could be a bad USB connection, try to change the USB port you're using or trying another cable.
