Help with first crown test

Hi guys

This is my first crown test.

I can reproduce this plot with the same results so I know my pen and media are not the issue.

I got the g code by copy & paste from the V1 web page in to note pad ++

please have a look at the jpg file and tell me what you think.

I am sure it’s just some adjustments that are needed.

Thanks in advance



Looks like mild backlash. The most common cause is pulleys that are loose on the motor shafts or loose belts. Check that first.


well it’s almost there, still have a problem with the circle not closing, and slight broken line. see pic.
