INVALID_ZERO_NEG_CONSTRAINT error while running 5 axis G code

Post by AmitKumar171 » Sat Dec 18, 2021 9:29 am

Hi Tom,

I am using Kflop+Konnect for my 5 Axis cnc machine.

I am facing strange problem (INVALID_ZERO_NEG_CONSTRAINT) while running attached g code.

I have attached the trajectory planner settings and G code in which i am facing the error. Even i tried increasing decimal in g code as well but still facing same error.

Please help me in finding the error and how to fix the same.

Waiting for kind reply.

Hi Amit,

That error shouldn’t come from GCode. It indicates a Move command from a C Program with a Max Velocity of 0. The C Program causing error might be invoked by an MCode within the GCode.

What line of GCode causes the error?

What C Programs are being invoked?

Hi tom,

Thanks for the earlier reply.

Only INIT file is running in thread - 1 , which has soft limit program attached with it (Soft limit is defined in axis definition files and checkdistancetostop also running in infinite for loop).

So does that soft limit making that error?

Waiting for kind reply.
Thank You
