Updating Your Rom; Cleaning The Outside Of The Nozzle; Removing The Nozzle - 3D Printing Systems UP PLUS 2 User Manual

12.3 Updating your ROM

Even if your printer is brand new, it is best to check you have the latest ROM version number in-
stalled on your printer. Currently the ROM update can only be updated using the Windows soft-
ware.
In the UP software click "Help" and "About UP".
1. Compare "Rom: Vx.xx" in the about page to the file located in to "C:\Program files (x86)
\UP\System" "UP Plus x.xx.ROM"
2. If your ROM version on the "About" page is lower, then follow 3.) otherwise you're UP
Plus is up to date!
3. Click "Tools" "Update ROM" and select the relevant ROM file for your printer and fol-
low the on screen instructions.

12.4 Cleaning the outside of the nozzle

After a lot of printing, the nozzle may be covered with a layer of oxidized black ABS on the outside
of the nozzle. When the printer is printing, this oxidized ABS may melt on the nozzle, and may cre-
ate discoloured spots in the model. To avoid this you need to regularly clean the nozzle.
Firstly, move the platform to the bottom, then do a "Withdraw" in order to heat the nozzle to melt the
oxidized ABS.
Lastly, use some heat-resistant material, like 100 percent cotton cloth or soft paper. A pair of tweez-
ers will also be required. Then clip paper or some other heat-resistant things with tweezers to clean
up the nozzle.

12.5 Removing the nozzle

Should the nozzle become blocked, you may need to remove it in order to unblock.
To remove the nozzle, first click Withdraw in the maintenance screen, then only
once the printer is at 260c, use the nozzle wrench provided in the toolkit that comes
with your UP Printer.
ONLY remove the nozzle when it is very hot,
trying to remove it while cold will damage
the extruder block!
If the nozzle is blocked, remove the nozzle and clean it.
