With some technical filaments i had sometimes the problem that the printer will fail at the “Cleaning Nozzle” stage due to the oozing or harder materials. Solutions like drying filament did not work out.
As a lot of other printers using a wiper to get rid of all nozzle debris i created a wiper which attaches to the bed holder. Its using the brushes from the BL A1 as they are super cheap to get from aliexpress/amazon.
Warning: You will loose 1mm of Y Travel at the X location of the brush due to the part cooling fan.
As this was designed very quick and dirty there is for sure a way to get full travel. Possible Remixes? :-)
