Hello,

Im having an issue with a few files that I created in Fusion 360.  It seems to be related to the IJ setting in Machs General Setup window.

Im trying to run this code:

G90 G94 G91.1 G40 G49 G17
G20

M5

T2
G1 X0 Y0 Z0.5

The machine throw this error, Cannot do g1 with zero feed rate, Block=G1 X0 Y0 Z0.5
I have tried setting the Mach 3 to absolute, closing and reopening the file and inc and closing and reopening the file but still see the error either way.

Wouldnt the first line (G91.1) override the default in the match screen anyway? 

Thanks

Change it to...

G1 X0 Y0 Z0.5 F10

Any time you use G1 after that it will move at 10 inches or millimeters per minute. If after that you want to move at a different speed just do another F#

This was it!!  Thank you.  Makes perfect sense.
