New vf6 has one random peck in a drilling cycle go very slow but the rest are normal.

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...

I hope this is just some playing around trying to get the machine to act poorly. If not... maybe it's simply the machine's way of complaining that someone just asked it to full retract peck 40 times at less then 1/10th diameter drilling a hole only 3 3/4 diameters deep. I wouldn't want to do that either... under any circumstance! : -) [elbow-elbow]

It doesn't necessarily kill DWO.
... probably. Who the hell knows? This is why I'm still using my own DWO macro and not the built in one. Was a bug a few years back where if drilling different depths with canned cycles, the final retract would be wrong. Sometimes close enough not to notice. Sometimes Z+ and sometimes Z-
In my case ruined a nice carbide drill and my collet chuck pushed the part out of the vise.

The problem I found right now is in TCPC. With G234 active, if you make a rapid or feed move, then call a workoffset, the next move could be your last, depending how your code is formatted.

For example:
(G234 is already active)
G0 XYZBC
G54
(this line is potentially crash-tastic)
If you call any other letters besides X, Y, AND Z, (all 3!) the movement is unpredictable. Even calling the exact same position you're already in with only X, only XY, only YZ, etc. or even BC angles, without all three XYZ, you will get unpredictable movements. Sometimes left, sometimes up, sometimes Z-9.

G0 X1 Y1 Z1 B50 C50
G54
X1

Will produce random movement in Y and Z directions. Even though you're already at X1, the machine will move in Y and Z to some unknown values.

Or

G0 X1 Y1 Z1 B50 C50
G54
B50

Will move XYZ some unknown amount.


So... make sure your code doesn't call a duplicate workoffset between movements. (my formatting had other codes between operations, but I've narrowed it down to simply calling the workoffset which causes the problem) Cancelling tool length with G49 and reapplying G234 would work fine. Or just don't call workoffsets while in G234 mode.


Probably my last Haas machine. The bugs are just ridiculous. Every time the control software is updated, are we supposed to prove out every possible operation and combination of operations each time, to be sure there's no other bugs? I just can't trust anything they do after seeing this. The sad part is if you have a problem with something on the machine, the first troubleshooting step for the service guy is a software update. No thanks... who knows what other undiscovered problems you'll find next.

Hoping I'm just being an idiot. But sometimes peck drilling it'll just do one peck in the cycle very very slow even though the current feed rate keeps showing its unchanged. Happens with random values but when it happens it'll do it in the same part over and over.

Here's a drill cycle I got to do it. I hope I'm just being dumb

Also does it with out dwo active. If I play with f and q I can get to happen or not happen.
