1. ## INVERSE TIME FEEDRATE OPTION FOR 6 AXIS

Hi All

I am using Kflop board for 5 axis. But now i want to use the same for 6 axis as well.

Inverse time feedrate option available in kflop is for 5 axis only.

I want to know that how do i use the same inverse time feedrate for 6 axis. eg X,Y,Z,A,B,C.

Thank You

Hi Amit,

Inverse time should work for any number of axes. Why do you say it is only available for 5 axes?

Hi tom, i want to know how to turn off inverse time feedrate option for 5 axes because it is causing jerk in machine movement.

I want to make machine movement smooth that is only possible without inverse time feedrate. How to turn it of for X,Y,Z,A,C axes.

Hi Amit,

I'm confused. In your first post you seem to want to use inverse time for 6 axes? Now you don't want inverse time for 5 axes?

Anyway,

G93 sets the Feed Mode to inverse time.

G94 set the Feed Mode to units per minute.

So use G94 to turn off inverse time feedrate.

Can you provide a simple GCode example of "jerky" motion?

Regards

Hi tom,

i am using following g code

G1 X-3.096 Y-41.478 Z70.724 A90.021 C-3.509 F1000

TO

G1 X-5.052 Y-45.586 Z65.724 A85.092 C-5.365 F1000

But when i run the g code in kmotion cnc i am getting feed of 5 and 6 MMPM but as i said in g code it is f1000 so it should be 1000 right.

How to make the feed rate from 5-6mmpm to 1000 mmpm or constant feedrate for 5 axis.

Hi Amit,

For me that GCode executes in ~ 0.4seconds which seem about correct. For you it takes ~ 1minute ?

What are all your Trajectory Planner Settings?

For me that second line of GCode executes in ~ 0.4seconds which seems about correct. For you it takes ~ 1minute ? Yes or no? How long does it take for you?

Hi Amit,

Like I said we don't see the problem here. So you will need to tell us what you are doing different.

Post your Init C Program and all GCode before the two lines of GCode.

Regards
