I was tried to print using mprint on mbot cube ll dual head, but only can configure for the right extruder, if i want to select the other extruder need to change the filament, additionally, when print a piece lika a cilinder with a close trajectory leave a mark at the beginning and the end, could some one advise me?
Regarding MPrint; You need to select the extruder before export file into x3g. Otherwise, right extruder will ok as defult extruder.
Mark at the begining and end; It seems two extruder are not parallel. You can check this link http://support.mbot3d.com/hc/en-us/articles/205353314-A-nozzle-adjustment-in-double-heads-printer for adjustment. If still problme then contact us at [email protected]
