Hi David,

Sorry I'm having a hard time reproducing the problem.

Could you send me the GCode you are using? Or still better could you test if the example spiral.ngc with M6 inserted at line 50 also has the problem for you.

Please post all your settings: Trajectory Planner Screen and your C Initialization program. Anything else "special" about your configuration that you can think of?

Have you Flashed any programs into KFLOP? Flashing "New Version" will eliminate this possibility.

Please try the latest Test Version:
