Acu-Rite CNC 3500i User Manual

7 Programming: Canned Cycles, sub-programs



When you enter a value, the CNC executes the number of passes 
required to get from the H (StartHgt) to the Z (ZDepth), cutting the 
B (DepthCut) on each pass.



When you enter an S (FinStock) value, the CNC leaves the specified 
stock on the profile and depth for a finish pass. The CNC cuts the 
rectangle to the M (Length), W (Width), and Z (ZDepth) dimensions 
on the finish pass. Enter a negative S (FinStock) to leave the finish 
stock without making a finish pass.



When you do not enter a J (RoughFeed) or K (FinFeed), the CNC 
executes feed moves at the current feedrate. J (RoughFeed) 
controls the feedrate of the roughing cycle. K (FinFeed) controls the 
feedrate of the finishing cycle.

CornerRad

U

Corner radius setting. If the programmer 
enters a negative value, both direction of 
cut and the starting and endpoints reverse. 

ZFeed

I

Z-axis feedrate.

Rough 
Feed

J

Rough-pass feedrate.

FinFeed

K

Finish-pass feedrate.

DepthCut

B

Maximum Z-axis increment used for each 
pass. 

FinStock

S

Amount of stock left by the machine before 
the finish pass. Default: 0. If the 
programmer enters a negative value, the 
CNC leaves the stock without making a 
finish pass. 

RetractHgt

P

Retract height.
