1.8 I'd guess is step angle, which equates to the normal standard of 200 steps per revolution suggested by Irving above.

My Conect is a beige one, and used different motors, however I think the controls were pretty similar, so I'd doubt they would change the motor specs too much between the versions. The motor details for mine are in the first couple posts at http://www.mycncuk.com/forums/mills-...ion-grows.html
