She´s a diva - problem with cycles

[Germy]

Hi there,

I´m quite new to this software and I´m having problems with running cycles:

Windows 8.1
1.22.2.452

It simply stops during the program. If I hit stop and continue it skips the line and does what it is supposed to do.
What is even more strange is the fact, that the same code every now and then does run as it is supposed to!?
I´ve spent two full days working on it trying to work out what is wrong, but I´ve given up on it for the moment. Hope anyone has got an idea what the problem might be.

Problem with G99:
It first started with a facing cycle. She did the first few lines, like g0 moving to the point where it was supposed to start, but didn´t want to continue its facing cylce in 9 out of 10 cases. I then altered the ...F.035... into a F0.035 and it worked. When I wanted to start the cycle again, same problem...

Code: Select all

O0000
N100 G21
N110 G28 U0. W0.
N120 G50 X15. Z15.
N130 G0 T0707
N140 G97 S2800 M03
N150 G0 X14.5 Z0.
N160 G50 S2800
N170 G96 S150
N180 G99 G1 X-1.6 F.035 <= stops here, no facing happening
N190 G0 Z2.
N200 X8.105
N210 Z4.7
...

I can´t cut any threads with the code I got, not even if I use the one provided in the help section.

even the code in the help section doesn´t work:

Code: Select all

NØ1ØØ	GØØ  X16.25  Z5.Ø  ;	<= move to position ok
NØ11Ø	G76  PØ3ØØ6Ø  Q15Ø  RØ.Ø3  ;
NØ12Ø	G76  X13.546  Z-4Ø.Ø  P1226  Q3ØØ  F2.Ø  ; curser stops in this line, but no thread cutting happening

I got the last code running once withouth altering anything. Just by stopping, rewinding and pressing play. After the 10th time it felt like working and did the cut
In some cases I got back the yellow message: Can´t cut thread or so but havn´t had this one again.


Any help is highly appreciated, as I got no idea what the problem is since it sometimes workes and sometimes not

Did you resolve this one?

What version of VR Turning are you using?

The current version is 1.42

It may be worth trying this.

It may also be worth checking the spindle speed and encoder feedback.

You are using constant surface speed for the facing cycle and unless the speed is correct it will hang up waiting.

Try running the spindle at different speeds and see what the spindle encoder feedback says the spindle is actually doing.

The encoder also controls the threading.
