New control has strange motion
« on: March 11, 2010, 12:42:26 PM »
With the following code, generated through the arc wizard

G0 G49 G40  G17 G80 G50 G90
M6 T1(TOOL DIA. 0.25)
G20 (Inch)
M03 S500
G64
G00 G43 H1  Z0.1
X1.125 Y0
G01 Z-0.1 F3
G3 X-1.125 Y0 I-1.125 J0 F5
G00 Z0.1
X1.125 Y0
G01 Z-0.2 F3
G3 X-1.125 Y0 I-1.125 J0 F5
G00 Z0.1
X1.125 Y0
G01 Z-0.25 F3
G3 X-1.125 Y0 I-1.125 J0 F5
G00 Z0.1
M5 M9
M30

I get good movement in the y direction but the x direction does not change until the second half of the arc, ending up with something that looks like a small n.
By the way, it looks and acts fine in Mach3 simulation.
Any ideas?

Then looks like you may have looseness in the X axis, check for backlash in the screw or slop in the bearing or a loose coupling..
