Hi Jayme, if you have MK2.5S, then you also need to install the extruder endstop block.
If it’s MK3, then make sure your textile sleeve is properly squeezed and zip ties are tightened according to the manual.
Hi Zerg, you need to replace the tube or your MMU2/S might not work properly - the old MK3 tubes have bigger inner diameter (2mm vs 1.85mm), which can result in problems with (un)loading filament.
Hi Jamie, you need to use a bit of force. But there is no need to remove it to attach the second arm.
Hi, we have found this way to be the best for disassembly. It’s not very important though, you could just remove the PINDA probe first.
Hi Christopher, we have included a ball-end allen key with all MK3 kits - you can use it now to finish the upgrade.
Hi Anne, we would love to include links to all the parts at many steps, unfortunately we can’t do this for technical reasons.
Hi Jim, it should be possible to do this with fingers only - tools aren’t necessary at this point.
Hi Anne, it should be OK - the idler will be pushed “out” once the filament is inserted, so there will be enough space if you don’t overtighten it (with the screw going through the spring).
Hi Rob, 6 feet aren’t necessary - the printer works perfectly fine with 4.
Hi John, please check this article, perhaps re-installing drivers will help you: https://help.prusa3d.com/article/gXdRubc...
