Definitely looks like under-extrusion. Calibrating is rather simple. Here is a video link: https://www.youtube.com/watch?v=PChOqIBNwOs
For this work, I pull the Bowden tubes out of the extruders, cut the filament at the face of the coupling, connect my laptop with Pronterface, issue this command ...

I had the same issue. Found a stress crack in the arm that is spring tensioned. Changed both out to the MK8 extruder and solved the issue. Had to re-calibrate the extruders since the Mk8's don't use a 3 to 1 dgear drive. Reduced the esteps to 97. Also had to flip the connector to reverse the ...

I found that after slicing in Cura 4.4.1 and looking at the G-code, the fan is turning on at a slow speed at the first layer and increases a little more on the second layer and goes to full speed on the third layer. This was causing curling of the outside edge of the print, even though I had ...

I received the A10T today and assembled it with no problems and printed the "Dog" test file and got excellent results. So I sliced a 3 color faced cube in Cure 4.6.1 with a retraction of 9mm, Print Acceleration's to 1000, Print Jerk's to 10, and disabled Retract at Layer Change, Print Speed 40mm/sec ...

What is the best extruder retraction distance for the A10T? I use 6.5mm for my A10M, but it is a totally different hot end.

It took a while, but thanks to your JSON file and some dialing in on Cura 3.5, I was able to eliminate my stringing problem and the extruder gear from shaving the filament. I used the two color Benchy for a test since it has some many changes with the two colors. Bleeding was eliminated by ...
