Title: ramp problem on z axis
Post by: Rafaelaaa on November 08, 2016, 09:12:03 AM

Hi
CNC 6040z 1.5 k

A week a go I try to calibrate z axis and was when the problem start.

If a make a z axis cut at 1 mm
It make a ramp from 0 to 1mm and stay there until have to go up after that start the same way 0 to 1mm and go on.
I use art cam pro and the ramp setting is in off the problem is when I run in mach 3  .

My machine is starting to move in x or y direction before the z has reached the correct depth

Two possible causes come to mind...

If the X, Y and Z moves are on the same line of code.
Try putting the Z move on it's own line before the X and Y moves.

If the Acceleration (in motor tuning) has not been set high enough and you are using Constant Velocity.
Increase Acceleration or try running in Exact Stop mode.
