I have an issue that im sure some of you know the solution. It seems linuxCNC/ AXIS processor  instead of completing a move to a coordinate begins moving to the next coordinate creating a curve/ bend toolpath between the two points, almost like a shortcut. It does this only from an X or Y cordinate to a Z and vise versa, but not from an X to Y coordinate. Please help !! thanks.

Greetings,

I think I had a similar situation.

I needed to activate G64 to tell the controller not to move until the previous event had finished it's travel.

Cheers,

Dave

Greetings,

I only gave you half of the equation.

Insert G64 P0.001 into the startup line at the top of the program.

The P parameter is what does the work.

If this cures the issue, modify your post to insert it automatically.

Cheers,

Dave

It's important to understand how Linuxcnc follows the programmed path.
linuxcnc.org/docs/stable/html/user/user-concepts.html

Note that G64 Blend Without Tolerance Mode is the default

A good preamble should always be the first line of any nc code program.
