The one from the LCD menu or the gcode end script.Of course, ramming above the board or in the purge tower is certainly not the same, but I hope to find someone (also in the Prusa team) who can transpose this equivalence into the toolchange script. This is the first time I hear that the heatbreak for v6 and MMU was specially made for this application.Another point that gives me hope is that unloading the filament can give satisfactory results. However, there are reports of the MMU working with Revo Six.However many users have been successful with the Hemera and the MMU system with some changes to the load/unload and ramming sequences.Please note however that this is untested by ourselves.If you have any further questions please do not hesitate to contact us. Greetings from E3D Online.Thank you for contacting us with your enquiry.The Revo Hotend range utilises a different internal geometry to that of Prusa V6 specific Hotend, Specifically the heatbreak.The Prusa Heatbreak was designed with MMU compatibility directly.we have not tested the Revo system with the MMU. I was curious to know if they made some real tests of the Revo with MMU. Here is an answer of E3D about this topic. Thank you in advance for your experience and help.Īnswered: RE: MMU2 with E3D Revo Six - Tunning filament tip issue I don't know what "Ramming" is and how to tune. I have already tried to increase "Unloading speed at the start" up to 120, 140 mm/s => not betterĪlso increased "Number of cooling moves" up to 4 => not better (even worse, a bulb instead of a thin string)įilment temperature not changed, 215☌ for PLA was OK with previous config. ![]() This is Generic PLA of PrusaSlicer original parameters : Should be theses orignal parameters in PrusaSlicer to be modified ? My measurement is a total length of 31.0-31.2mm to be installed in the MK3S+ extruder body R6. The new Revo Six hotend have same external dimensions as the v6 to be installed on the MK3 series, but inside the PTFE tube is approximatly 11 mm shorter (to compare as the 42.3mm config). Theses thin strings clogged the system by accumulation after 10-20 filament changes.īefore doing a more detailed explanation, I would like to know if the problem has appeared with other users who have recently installed the Revo Six and tested with the MMU2?įilament PLA, generic and Pusament, dry enough. This is more marked when changing filament on the purge tower than when unloading the filament via the LCD menu (these parameters there seem quite correct and the point is as it should be).Ĭonsidering the internal design of this new hotend, I think there is a cause. Since I have installed the new E3D Revo Six hotend (rapid change of nozzle), the tip of the filaments (Generic PLA) have a long thin string at the tip during filament changes on the MMU2. ![]() ![]() MMU2 with E3D Revo Six - Tunning filament tip issue
