Unit Inch/MM, Dimension Abs/Inc, 137 | Acu-Rite CNC 3500i specs

Unit (Inch/MM)

Use the Unit block to specify and activate the desired unit of measurement in a program. The active Unit is modal, and remains active until overridden.

Select the More Milling button, and then "Unit" from the pop-up menu.

Conversational format: Unit

G-code format: G70 (Inch), or G71 (MM)

Field	Code	Description
Unit	U	The desired modal unit of measurement to
		activate, Inch or MM. (Required)

Dimension (Abs/Inc)

You can change the program mode to Absolute/Incremental. Specify Absolute or Incremental mode at the start of a program. Refer to chapter 3 "Manual Data Input (MDI)" on page 38 for more information regarding Absolute and Incremental programming concepts.

Conversational format: Dim

G-code format: G90 (Abs), or G91 (Incr)

Field	Code	Description
Dim	D	The desired modal dimensional
		programming method to activate, Absolute
		or Incremental. (Required)
