On long print jobs some types of plastic might accumulate on the nozzle and will eventually drip on the print which could, in the best case create lower qualify prints and in the worst case cause the print to completely fail.
This plugin will automatically wipe the nozzle every few minutes by pausing the print and moving the nozzle to a wipe area were you can "install" a wiping system. This could be as simple as a wire brush glued to the bed or something more complex like a motorised rotating brush. After a few wiping moves the print is resumed.
