Good thing to see tech support in other countries are disconnected from the engineering / development community as well like the US.
I questioned response #1 as I was inquiring with XYZware software revision change and they comment on firmware. Response #2 is what followed.
Response #1
The firmware update is needed for the printer to support the PLA filament that will be released soon.
Since the printer now only supports the ABS filament in the new firmware it will automatically detects that the new filament installed is a different type of material and change settings that will support the material characteristics.
Response #2
Please always update the xyz ware and firmware to the latest version. However, the printer will distinguish different filament automatically.
