REGARDING ROTARY AXIS BACKLASH

[AmitKumar171]

Hi tom,

I am using kflop for my 5 axis machine.

Which is having 3 linear axis (X, Y, Z) and 2 rotary axis (A, C).

I am facing problem related to backlash, which i want to adjust in my init.c file.

My A axis is having gearbox which is having reduction ratio of 1:39, but also having a backlash of 1 arc-minute (0.016 Degrees).

I want to adjust same backlash in int file eg.

ch0->BacklashMode=BACKLASH_OFF;
ch0->BacklashAmount=0;
ch0->BacklashRate=0;


the above code i have in my init file. I have seen the manual also which says that backlash will be (BACKLASH_OFF, BACKLASH_LINEAR).

For rotary axis A , how should i adjust because rotary backlash setting option is not there as shown above. ?

Is there any separate option for adjusting rotary axis or gearbox backlash.

Waiting for your kind reply.

Hi Amit,

Configure it the same as a linear axis.

Hi tom,

Thanks for the reply.

I will test the same and let you know the results.

I have one more doubts regarding maximum frequirency of pulse generating in kflop.

KFLOP has 8 axes of Step and Direction. Output pulses up to 2.5 MHz can be generated.

In the above line in your manual , does that mean for 2.5MHz for each axis then 8 axis will be 2.5 * 8 = 200 MHz, ? or
2.5MHz is for all 8 axis combining. ?

or what is the maximum speed in usteps/sec pulse that kflop can give combining all 8 axes.

Waiting for your kind reply.

Hi Amit,

2.5MHz each axis independently.
