Ok, we have given up on the Flex3Drive/ED3 V6 for now, will return to this after getting some answers as to why the stepper motors won’t run at the required steps_pr_mms.
Now, with an MK8 DD the 20mm calibration cube is 20.67mm in X&Y and 20.87 in Z. What exactly are the changes and where to make the change?
Please answer this question, I am also looking into this. Thanks
