309 error on haas

[Anonymous]

So after i post any program from inventor, and my machined is set up. once i start running the program, it will do one pass then stop and give me a 309 error which is exceeded max feedrate. i have tried to lower the feedrate and it still give me the error with any tool/function. what can i do, or is there anyone that can help set up a program?

It is likely the high feed rate from the options in the post dialog.

I was thinking the default was 650ipm in the post.  I have a VM3 that is limited to 500ipm and a VF3 non SS model and I think the max feed is 633ipm

Weird, every new Haas post I've seen is 500 standard. I'm guessing that the Non-Engagement linking feedrate rate is to blame here though if he gets as far as a first pass. What toolpath is this in @Anonymous ?

[Lonnie.Cady]

@Steinwerks the newer post may have changed to 500ipm.  I am not sure how old mine are.  When I RMB and select reset to built in default it goes back to 650ipm.  I am not sure where the post defaults are stored.

[Rob_Lockwood]

The built-in default is set in the post processor, and it appears the (current) default haas.cps has it set to 500ipm.. But it's entirely likely this was reduced at some point.

highFeedrate = (unit == IN) ? 500 : 5000;

So what would I do to fix my problem?

What is the value when you are posting the code?

make sure that feedrate is below the value in parameter 59 in the haas control.  I just checked and on my VM3 it is 500ipm.

You can embed those you know.

I found an error if peck tapping.

when it does a G80, it does not do  G94, to turn inverse feed off.

if you add G94 to the G80 line it will work.

I have been having this problem on our HAAS VF4 and Programming inside Fusion360 using the HAAS A axis Pre-NGC post they provide.  It seems that the code outputs some arc'd movements inside the parallel 3d toolpath that show up with a G2/G3 movement, and I, J etc. and then a Feed rate that is 1500 IPM.  This 1500 IPM seems to cause the error 309 on the HAAS control.  I have been editing out that F1500 to change it to F500 and it runs fine after that.  I am trying to determine where in the post that 1500 IPM comes from so I can edit it to no longer cause this error. The Post browser has the (built-in) High feedrate setting but it was always set to 500IPM anyway so the problem is somewhere else.   Any help would be appreciated.  Thank you.
