Grind Cycles

G241 In-Feed Grind Cycle

Move the selected grinding axis through a series of moves and then Sparkout and retract.

  1. Feed move to "Rapid End Position" at "Rapid Feedrate"
  2. Feed move to "Coarse End Position" at "Coarse Feedrate"
  3. Feed move to "Medium End Position" at "Medium Feedrate"
  4. Feed move to "Fine End Position" at "Fine Feedrate"
  5. Dwell for the Sparkout amount of time in seconds

Descriptions of parameters:

A - Rapid End Position
B - Rapid Feedrate
C - Coarse End Position
D - Coarse Feedrate
E - Medium End Position
F - Medium Feedrate
H - Fine End Position

J - Sparkout Time

G246 In-Feed Retract Cycle

Move the selected grinding axis to the retract position

  1. Rapid move to "Retract Position" 

Descriptions of parameters:

R - Retract Position
