Hello, I wanted to perform the first print, but it does not work as it should. I can´t print more than 9 layers. The printer always kicks the boat from the glas. The needle is on 210°C, the glas set on 50°C. The voltage was set to 0,595 Volt (Stepper tuning). Is the Z-Axis to slow? It was set to 400mm as mentioned in the build manual. The extruder put´s 100mm of material correct into the extruder. The printing looks in the first layers great. After layer 4 it gets really rough and does not look good.
