Delta DVP-20PM

6 Basic Usage of Motion Instructions and G-codes
 Two-axis arc interpolation: DVP20PM00D only supports circular interpolation on
the XY plane. DVP20PM00M supports circular/helical interpolation on 3 planes
by G-code instructions: G17 (XY plane selection), G18 (ZX plane selection) or
G19 (YZ plane selection).

 Helical interpolation: Helical interpolation is applicable to DVP20PM00M. Three
axes which are perpendicular to one another are used. They move
synchronously. Helical interpolation is the extension of circular interpolation. If a
helical interpolation instruction is used, and the change of height is zero, circular
interpolation will be executed.
 If G17 is used, and the position of the Z-axis does not change, helical
interpolation will be equivalent to circular interpolation.
