Problem: 

In certain situations the WorkSeries controller will not resume after pausing a print.  The printer will hang and not respond to input, this problem is intermittent

The issue was identified on testing: WorkSeries controller resume script has a temperature check which will sometimes hang even with relatively small temperature variation.

Solution:

Modify script /sys/resume.g on the SD card to comment out the M116 line.  This modification can be done either through the web interface or SD card (remove internal micro SD card from machine).  If you are unable to update via web interface, the files may be marked read only and must be updated directly through the internal SD card.

Note: The system files are stored on the internal SD card, you will need to remove the cover using a 3mm hex wrench to access this card.  Do not edit any other system files when making this adjustment.

Power off and unplug the printer.

Remove the SD card from the printer controller (located on the back edge of board near the USB cable),  Insert the microSD card into SD card reader on your computer.

You may need to clear a read-only flag on the script file (resume.g).  If so, right click on the file, and click "properties." Uncheck the "read only" checkbox.  Click "OK."

Once flag is cleared we can edit the file. Open resume.g in a plain text program. We recommend WordPad on Windows, or Notepad++ although others will work. Right click the file, select "Open With" and choose your text program.

With the file open, look for the line starting with M116 and insert a semicolon ';' at the beginning of the line.  When you are done, the line should look like this:

;M116    ; wait for all temperatures to settle

Save the modified file, safely remove SD card from computer, and re-insert the SD card into the printer controller.  Replace all covers and restart the machine.  Resume functionality should work.

If you have access to the web interface the process is much simpler, simply open the web interface, and navigate to Settings > System Editor.  You can then look for the resume.g file and edit it from this view using the green "edit" button.  Once saved this file will automatically update on the controller.  If you get an error message such as "cannot write to resume.g" or similar, you will need to follow the steps above to remove the SD card from the controller for editing.
