Plunge feed rate missing

[GREG]

When ramp feeding with plunge feedrate ticked , there is no feed rate posted in programm so its doing it at rapid.

We are running V9 sp1 and using a modifyed Heidihain conversational post.

Where do I start lookig.

Thanks in advance

Watch out for that drop bear,

 

Let me guess you are using the Heidenhain post from the version 9 or 8 cd, and if you do a 2d pocket with the same feed rate as plunge rate then you get no feed rate output in the program so hence the machine defaults to rapid. How am I going? I will save you the headache and the time that it took me to work this baby out.

 

change pfr in your post to this

note the # sections are already there, putting this (#) infront of the block means that the post will not read that line

 

pfr # Feedrate

#if fr >= zero, fr2 = fr

#if gcode = zero, fr2 = zero

#if fr2 > zero, strf, fr2

#if fr2 = zero, strf, smax

if fr = -2,

[

if prv_fr <> fr, "F 9999"

prv_fr_pos = -9999

]

else, fr_pos

!fr

 

Note that I use F9999 not FMAX

and add this to the format statments

 

fmt F 5 fr_pos

 

works perfect
