Final Firmware Update Notes

  • When printing via SD card, You may experience issues with longer file names as RAM usage is higher. We are aware of this but the current solution is to keep your file names under 8 characters. Also, do not use your SD card as a storage device. Instead, keep the files stored remotely and only add frequently printed files to the card.
  • If the firmware version did not change, Initialize EEPROM manually through the Tools Menu (Settings>Tools). For example, DW7 updating to another variation of DW7 needs the EEPROM initialized. DW7 updating to DW7.1 does not as a version change will automatically clear the EEPROM.
  • After updating the firmware please use the values recommended in the following document to adjust the Levelling Sensor XY Offset of your unit : Level Sensors OffSets for DDX
    You can learn about the added User Interface screens and how to change the offset values here.
