    I don't know about the rest of you but I am tried or fighting with the rubber wiper. Has anyone else successfully implemented something else to replace it?

    Did you fit the updated wiper bracket? There are some handy mounting holes for anyone that wants to experiment :)

    If anyone has experimented with these mounting holes, it would be great if they could put up some web links with things they've mounted. Any obvious thing would be a brass brush, but I can't find anything quite the right length.

    I have that set here. I'm guessing the soft brushes wouldn't be ideal as the hot end would begin to melt them? It had occurred to me that the steel might wear out the brass, but the brass will too huh. OK. Well I have a hardened steel 0.4mm here already so, I could definitely fit at least one. Thanks for the input.

    brass brush is the one to use. don't use the steel brushes they are too abrasive.

    My "fix" is wipe the nozzle about 4 times in the start g-code.

    I do have the new bracket. I will try the suggestions :)

    My struggle is it difficult to get the rubber into the slot, I thought I had a good idea by streaching it so it was a little thinner. Well turned out to be very bad after a few wipes the rubber split. Now I have too small pieces of rubber I am fighting to keep in place

    Somebody talked about using a toothbrush!

    I cut one off but never got around to fitting it. ;-)

    Will a tooth brush resist >200° C?

    Ask Richrap.

    The answer may be that the nozzle passes over pretty quickly.

    I have concerns that this would be only a short term solution. Even if you move the nozzle quick over the brush you might leave hot filament behind...

    He was quite emphatic in his recommendation at the time on G+.

    I went out and bought one (because mine's electric!), cut it off but in the end didn't fit it because the rubber wiper has been in exactly the right place for a long time now and doing quite a good job. But I really hate adjusting it.

    Instead I have a different wiping problem. With mesh bed levelling and a hot nozzle I find that after auto-home and when a the nozzle is heading to the dock to extrude and start a print, the nozzle drags in a long diagonal across the glass and, since it's probably oozing, leaves a mess. That's a part of the print area don't use on smaller prints and then after a few prints an annoying line of plastic builds up that is not quite important enough to pick off but that one would want to clean if doing a print that extended into that area.

    Is this fixable with G-code or something?

    From where do you start your print? From the dock? At which height is your bed when you start?

    At present my start script does an autohome, then the print begins..... Which means it goes to the dock, extrudes and then heads out to print.

    For various reasons (preheating, a follow-on print....) the nozzle is often hot even at the auto-home stage and so the mess occurs as the nozzle wipes its way back to the dock after the autohome, because at that point it's very close to the bed.
