I can only think that it has to do with the extrusion engine, the bondtech (by the way, it is rusted) or the firmware is not correctĮdit: The machine I have not disassembled again the truth, I made all the possible checks, but I have not dismantled or printed the new parts When I contacted the technical service, they told me to check all the screws and check the belts, and I checked everything, I tightened and relaxed the belts, I checked if something rubs, I put other filaments, in some it is more difficult to appreciate this inconsistency in the extrusion. In certain geometries, it behaves better than in others. I have tried with prusacontrol, slic3r and simplify.

I recommend a full teardown of the machine (leave the frame and the motors) then reassemble and take your time checking everything that can move on the printer, like is the bed pr the x carriage showing slip stick effect, are the belt rubbing on the idlers, are all grub screws tight, etc.

wrong setting on the filament spring tensionerīasically everything that has to do with movement.

issues like slip stick effect, which cheap bearings can have. Please don't use white filament, or you'll go crazy (white filament is horrible to print with, requires absolutely perfect tuned machines) Usually Silver is the color which masks most faults of the layer lines (shadows from layer lines), but try bright orange or red for example. belts rubbing against the plastic parts or the pullies of the printer. The layer lines can have to following causes: Always good to countercheck with someone else.įrom the looks of your pictures, i'd say it's a hardware cause. This way you can rule out hardware errors or software errors. I don't have my MK3 yet, but someone here should be willing to print your sliced XYZ calibration cube (stock 0.20 prusa profile for the MK3), or you can print a gcode from a fellow MK3 owner here.

The only thing I have not tried is to disable all those functions. I have done all the checks as you can see in the previous photos with many tests and others that went to the trash.
