G33.1 taping

Hi Guys

I have wrot a small testprogramm where I want to check some functions on my machine.
When the machine arrives at G33.1 the Z axis will go down and do tapping,
when the Z Axis is down and the spindle will revers then the Z- Axis will move up in rapid feet.
when the programm do the 2. cycle it will be OK
What is wron in this Program
Attached is the Programm

Thanks

Thomas

Are you saying that the tool spirals down as expected, but then backs out at the rapid rate when the spindle reverses?

If so, then I don't think that is a G-code problem but a machine problem. Does the encoder count correctly in both directions?

Hi andypugh

yes when the Spindle will revers, then the Z- Axis muve up in highspeed ( as fast as the Axis can )
And the encoder counts, I see the speed in the display in bouth directions.
When the Programm repead the 2. time the tapping will work.
Is the Program OK?

Can you check that spindle-pos counts up in one direction and down in the other (probably just by turning the spindle by hand)

It looks OK, though tapping in incremental (G91) mode seems a little unusual.

Can you run a test in air with the G33.1 running in G90 mode?

G91 ought to be OK, but perhaps you found a bug?

Hello andypugh

I installed the 2.6 version to check if the problem is gone.
Now the machine moves to the position where I want to tap.
The Machine only stops.
I dont know why.
you see on the picture the Speed from Spindle and the Z-Acis want to go 130mm in plus? Why?
The tappinghole goes to minus direction.
Where can I look why the Program stopps?

Is it possible that it is waiting for an index that isn't happening?
