Unexpected High‑Feed G1 Move Injected Into Finishing Pass

Kiri:Moto CAM
1

During a finishing operation, Kiri:Moto generates a move containing a high feedrate (F6000) at a point where no such feedrate was defined in the operation settings. This feedrate becomes modal and causes the remainder of the finishing pass to run at an unintended high speed.
Observed Behavior
In the generated G‑code, the following line appears between two contour segments:

G1 X6.3614 Y10.8347 F6000

This line:
• Occurs inside a finishing pass
• Uses instead of
• Introduces even though the operation’s feedrate was set much lower
• Is not followed by a new feedrate command for the next cutting segment
As a result, the finishing pass continues at 6000 mm/min, which leads to excessive load and step loss on the machine.

It was during the contour pass right at the end of the NC file:

I found the code where it goes wrong (also on other nc files):

G1 X84.1288 Z-26.0100
G1 X83.9168 Y8.9093 F6000
G0 X84.5141 Y9.6630 F500
G1 X84.3857 Z-24.4450
G1 X84.2573 Z-23.5639
G1 X84.1288 Z-22.8443
G1 X84.0004 Z-22.2454
G1 X83.8720 Z-21.7529
G1 X83.7435 Z-21.2977
G1 X83.6151 Z-20.8853

It sets the cutting speed (G1) to 6000 and then sets the travel speed (G0) to 500, after that it continues with G1 commands without F-indicator and that will travel with F6000 (Makera limits at 3000).

I changed to the area operation, that’s way better.
