Placing components does not work

Hi all,
after finishing the basic setup I tried to place some parts using the Hello World example.
After setting up the tape, I performed a homing, a Re-measure and a needle calibration. An alingment test of the tape position shows this result, not that bad I would say.

But the result is not what I expected, tried a couple of times, with and without Slack compensation, used different needles (blue, purple), but nearly the same result every time.

I have repeated the basic setup a couple of times to be sure that I did not missed something.
May be some one has an idea what went wrong and how to fix it ?

Can you post your "hello world.csv"? I know it is downloaded from here... but I'd still like to see it. I noticed some oddities in different versions that I've downloaded.

Looks like your rotation direction/smount is off. Please double check: Alt+Shift+F10 should be 90 degrees clockwise.

Thanks for your answer!
One question: Does "clockwise" means: view from top-down direction or bottom-up direction?
Thanks in advance!

Top down.

Hi,
we tried it again, but the problem isn't been solved.
With a rotation <= 90 dregrees, the components have been placed mostly accurate.
With a rotation > 90 Degrees the are mistakes as shown on the picture.
Could this be a hardware or a software problem?
Thanks in advance!

The software has been in use for more than a year. I would be very surprised if we would discover a bug in so fundamental area, I would think that this is a hardware issue.
There is a Test A button on the basic setup tab. It turns the A axis full turn and back. Also the there are buttons that move x, y and a simultaneously. These are to ensure that the mechanics work on full range of machine movements and that the current settings and power supply capacity are sufficient.
Hint: It is difficult to see the A axis movement unless you put a piece of tape on the tube or (as I did) draw a mark on the pulley.

Hi caprisonne,
maybe your TinyG config is messed up?
Try sending the following command to it: $4po=0
This will make sure A-axis motor is driven as intended (not inverted).
Then make sure to have the wiring correct; increasing A angle should turn needle counter-clockwise (looking from above).
Make sure the part rotation in tape setup is correct.
Also, check your E-CAD program file (CSV) for corect rotation values. The preview in Juha's software should be helpful.
Use this for reference:
