Always getting max feedrate when posting

[turtlepower]

Hey I need help with a Fanuc post that for some reason will ONLY post out a feedrate of F999999 on any contour/surface path.

 

We recently acquired a second cnc boring mill and simply moved the post over and updated it to X4. (The fella on the first machine refuses to go past X2... I know, I know *cringe*). And since this update, other than a few minor changes I had to make, like the tool change code, the feedrate has me stumped.

 

What do you need from me to help? Whats my next step?

 

Thanks so much!!

when you did the update were there any errors in the update log? Alternatively you can open up the post and search for the string "#CNC". This would mark any errors that were encountered during the update.

 

Was this an mpmaster based post, a base post from the install or a custom post developed for you?

 

My guess is the post is reading the wrong parameter number from X4 based on the X2 parameter number. Have a look in the post for something close to this:

# Machine Definition Parameters

fprmtbl 17000 14 #Table Number, Size

# Param Variable to load value into

17391 axis_label #Axis label - 1=X,2=Y,3=Z

17397 srot_label #Rotary Axis label (Generally A, B or C) - Not yet available.

17401 rot_zero #Rotary zero degree position

17402 rot_dir #Rotary direction

17408 rot_index #Index or continuous

17409 rot_angle #Index step

17410 rot_type #Rotary type

17605 min_speed #Minimum spindle speed

17058 maxfrinv #Maximum feedrate - inverse time - inch - Minimum value from MD as this is inverse time

17066 maxfrinv_m #Maximum feedrate - inverse time - metric - Minimum value from MD as this is inverse time

17992 maxfrdeg #Maximum feedrate deg/min

17055 maxfeedpm #Limit for feed in inch/min

17063 maxfeedpm_m #Limit for feed in mm/min

17101 all_cool_off #First coolant off command shuts off ALL coolant options

Update log is as follows. This was an Mpmaster post that has had some tweaking in the past for X2. Now that we are on X4 with the second machine (same controller but purchased used so the parameters are obviously uniquely set). As an example, it was posting a G100 for toolchange and I was able to change that to M906.

17006

in the X5 nci & param reference is listed as: use machine inverse time values, removed for X3

and the others listed have to do with feedrates as well.

here is a screenshot.

 

I would say you need to figure out the intent of the parameters listed in the .err file and update them in the post manually...

[Chris McIntosh]

make sure the parameters in your post are update to the following parameter numbers:

 

17605 min_speed #Minimum spindle speed

17058 maxfrinv #Maximum feedrate - inverse time - inch - Minimum value from MD as this is inverse time

17066 maxfrinv_m #Maximum feedrate - inverse time - metric - Minimum value from MD as this is inverse time

17992 maxfrdeg #Maximum feedrate deg/min

17055 maxfeedpm #Limit for feed in inch/min

17063 maxfeedpm_m #Limit for feed in mm/min

 

You should have a table using some of the same variables.

Thats the answer!!! Those variable changes are what had me stumped! Thanks so much for the help.

 

I have to wonder though why these variables are even changed from version to version? Anyway, thanks again for the assistance.
