Under extrusion and E-Step on new A20T

Post by benjche »

Hello, I bought a A20T last week and I've printed perfectly the original Cat with the Gcode on the SD Card. Everything was fine.
But with a simple XYZ Calibration cube, or every other STL, i'm in total under extrusion !!! I must change the E-Step to around 780 instead of the original 395mm to have a normal print ! :shock: What's the problem ? :roll: I use the original Firmware and the Original CuraProfile of the Geeetech 3D Printer website !
