@C.Harris That guide was good, I had already dialled in the extrusion itself. However, good to check it’s still accurate, which it was.
The calibration cube in vase mode prints out at about 6mm/s. Have to say the layers look so good at this speed. Layer Height: 0.16
This really helped dial in the dimensions. However, I’m left with one frustration as all of the sides are very close after calibration, apart from one. I have 0.46,0.47,0.48,0.53?. Bit frustrating, I can perhaps go next level with the calibration cross and fiddle with the axis steppers, just more time consuming and not sure it’s worth it, unless others have or would recommend another guide for this?
