I have just finished building my Primo. I can draw with a sharpie pretty cleanly, but when I attach an extruder and print the print walks off to the left in the x axis pretty severely. I made a spiral vase print to see if it was coming from the movement between layers, but it also walks off doing a spiral.
I have it built x48 x y24 x z14, with 3/4" conduit. I use a separate bed that has 5" of vertical adjustment but is stable. I am using the v1 dual end stop firmware and the v1 tft35 firmware. I am printing at 25mm/sec.
The model in the photo should be symmetrical!
Any help or ideas on what could be the issue are appreciated.
This photo is drawing with a sharpie at 60MM /sec. a few wobbles, but pretty clean for 60mm/sec.
