Haas VF-5 is feeding very strangely when using G83

My brand new VF-5 was peck drilling using code G83 with a Q.05 and F1.3 all was going fine until one of the pecks seemed to stop, but it didn't it was moving at about .0001 per second once it completed the peck it retracted and continued as normal. Haas said it has had this complaint from other people and is working on a software fix.
Just thought you guys with new machines would like to be aware of this problem.

We have a brand new 07/2021 VF3YT that is having the same problem. We wound up changing the job out from the VF3 to the VF2 and it seemed to work fine. Bad was changing out from the 50 taper holders to the 40 taper holders.

I read somewhere recently that the Haas control acts funny on G83 after some number of pecks. I think it was 20+.

Increase your Q to reduce the total number of pecks and see what happens.

I'm having the same issue on a 2022 VF2 and would be very happy to find a solution.

Yes it is after every 25 pecks. So 25, 50, 75, etc.
It'll get through the peck just fine if you bump up the feed.
This was fixed in the newest software release. I had mine updated last week and it is working now.

Although now they have bugs with DWO/TCP again. Almost ruined our new UMC. Running old repeat job, luckily the operator was going slow because it's a "new machine" but noticed odd movements. Luckily stopped because a few movements later it would've took a nosedive into the table at an angle.

On one hand its great all the new features they add, but on the other it's fucking pathetic since they cause so many problems with things that should just work.

I wonder if it would do the same using G73? If you use a K and Q in G73 it will full retract at the K value.
I have used G73 this way for years. I think it works much better than G83 with no noticeable time difference.
Just a thought.

You know, this is so F-d up!

How many, 7, 8 years now with the NGC?
And we still have issues with shit that worked from day dot on the old control?
Just what kind of newcomers writing code for Haas these days, and just who is supervising them?

Apparently this is just another stupid, needless bug.
Lemme ask: Do the new software versions still treat the P word from a M97 subroutine call as a dwell for a G8x cycle?

All of my NGC-s do!

G00 X0 Y0 Z.05
G83 Z-1. R0 F2. Q.1 P.1
M97 P9000
N9000
X1. Y0
X2. Y0
X3. Y0
M99

Hole @ 0,0 will get a .1 sec dwell, all the rest has a 9 second dwell.
Guess why?

I'm going to try that

Exact same issue

After weeks of nobody responding I stopped looking at this post.
Hass had a few workaround ideas and I rejected them ALL. The machine works for me not the other way around.Haas came and "upgraded" the software with the previous version and it fixed the problem.

I am glad you found a decent remedy. At my last gig we had a new VF-6 that would generate an overtravel alarm in the middle of the travel. It was traced to a bug in the software with having high-speed or linear rapids turned on; I cannot recall exactly. Anyway, in the end Haas bailed on us and simply told us the option was intended for 5-axis models, not for VF models, even though those options as well as a host of others were touted by the salesperson for selling points.
