Accuracy and repeatability are key facets of a – homemade – cnc machine.
This is also the hardest to achieve.
I am definitely not disappointed with inaccuracy of about 0.02 mm, on my home made machine.
A precision of about 0.05 mm is considered a acceptable average backlash.
To make technical and kinetic art, accuracy and repeatability are a requirement.
So after two days of cleaning and tuning I am very contented, and the work can (finally) resume …….
until the next problem, hopefully not too soon ….
