Newfangled Solutions Mach3 Wizards / Multi pass odd behavior

« on: July 15, 2014, 10:04:00 AM »

After a couple of years away (health issues) I am getting back into CNC things.

I updated my Mach install with the recent Mach 3 with wizards. I saw that the old z-inhibit is gone.

So now it is a matter of updating saved code with the Multi Pass Wizard!

I have the latest Mach 3. Running the multi pass wizard against this:

G0 G49 G40 G17 G80 G50 G90
(-- Set Z zero to bottom of part --)
(-- Final Z is set to 1.125" --)
(-- Use Z inhibit to incrementally plane --)
G20 (Inch)
G90
f3
G0 X0
G0 y0
g0 z1.300

g1 z1.125
M3
f6.5
g1 y-9.3 x0.5
g0 z1.300
M5
g0 y0 x0

M30

I put in the values for rapid (rapid height), increment (z increment), and depth (depth limit) then convert.

The path generation dialog comes up and does not dismiss. I have let it run as long at 3 minutes. All it does it keep adding lines to the file:

G0 G49 G40 G17 G80 G50 G90
G20
G90

G0 X0
G0 Y0
G0 Z1.4

G1 Z1.4
M3

G1 X0.5 Y-9.3
G0 Z1.4
M5
G0 X0 Y0


G0 G49 G40 G17 G80 G50 G90
G20
G90

G0 X0
G0 Y0
G0 Z1.4

G1 Z1.4
M3

G1 X0.5 Y-9.3
G0 Z1.4
M5
G0 X0 Y0

G0 G49 G40 G17 G80 G50 G90

G20
G90

G0 X0
G0 Y0
G0 Z1.4

G1 Z1.4
M3

G1 X0.5 Y-9.3
G0 Z1.4
M5
G0 X0 Y0

G0 G49 G40 G17 G80 G50 G90
G20
G90

G0 X0
G0 Y0
G0 Z1.4

G1 Z1.4
M3

G1 X0.5 Y-9.3
G0 Z1.4
M5
G0 X0 Y0 ...

Thousands of times. The longer it runs the longer the file gets. It does not complete. It can be stopped using the Cancel button.

Not only does it loop, the added lines do not actually increment the Z. It stays stuck at 1.4.

Seems simple. Z down, traverse, rapid Z up, return to x0 y0, do it again.

Any thoughts on what would be confusing the wizard?
