Introduction: Da Vinci Junior (Jr) Firmware Downgrade
This process will let you load firmware on the XYZ Da Vinci Jr Printer. The Step are for Windows. Step 13 has a method for changing firmware on a Mac.
Step 1: Checking Your Printer Firmware Version
On the printer display at the home screen. Scroll down to the "INFO" options and press the OK button.
Step 2: Checking Your Printer Firmware Version Continued.
Scroll down to "SYSTEM VERSION" and press the OK button. This screen will tell you the firmware version the printer is running.
Step 3: Changing Your Printer Firmware
In order to change your printer firmware you will need to download the file attached with this step to get what we have been calling XYZware with advanced mode enabled. This is an older version of the software that has a special advanced mode enabled that gives you much more control over the printer. The advanced mode has manual controls for your printer, a gcode editor that can allow you to manually change temperature settings, speeds, and many other controls. It also allows you to load firmware from a file instead of downloading from the server.
The first step is to download the attached file, unzip the file and save it in a place on your computer.
Step 4: Loading XYZware With Advanced Mode.
You will need to browse to your program file which are typically on your c: drive and select the "Program File" or "Program Files (x86)" depending on your computer and setup.
Once in the Program Files scroll down to and select the "XYZware" Folder and select it.
Once in the XZYware folder replaced the xyz.exe file with the one downloaded in the last step. Just copy and paste the file downloaded over the existing file.
Step 5: XYZware Advanced Mode
Once you have copied into the folder you should be able to open XYZWare as you have in the past. Please see the picture on this step. The area to the right with tabs and options will be the confirmation that you have successfully loaded the software.
Step 6: Loading New Firmware
Attached to this step are 2 files of past firmware. Please download the file you would like and save it on your computer.
Step 7: Putting the Printer in Bootloaders Mode
In order to Upload older firmware you will need to put the printer in bootloader mode. Press and hold both the up and down arrow on the control pad and while holding both buttons turn the printer on. When the printer loads the screen will say "Bootloader" on the screen as shown in the picture for this step.
Step 8: Loading Firmware
Open XYZWare with advanced mode. Then selected the "?" icon at the top of the window.
Step 9: Loading Firmware
Once the About window loads select the "Firmware Upgrade" Button.
Step 10: Loading Firmware
When the popup loads saying new version available, upgrade now select the "No" option, so that you can select the firmware you want to load.
Step 11: Loading Firmware
Once you say no it will load an explorer box. At this time select folders to get to the location where you saved the firmware file you want to load and select the file.
Step 12: Loading Firmware
Once you have selected the file the firmware should load. The above screen should appear showing you are loading and after 30 to 45 seconds the printer should restart and your new firmware should be loaded.
Please ask any questions in the comments and let me know if something isn't working quite right.
Step 13: Mac Firmware Changing
I have not confirmed with process personally, but here is the short version reported for changing firmware on mac.
It was done using Mac version of XYZWare (latest), so no special "advanced mode" required.
Put the printer in "Bootloader" Mode
In XYZware while holding the Alt/Options key click in the "?" icon.
In the about screen while holding the Alt/Options key click the "Firmware Upgrade Buttton"
This will open Finder - locate the firmware file and select it and the firmware should update.
Please ask any questions in the comments - anyone that can verify this please say so in the comments.
