Hello,

I get no good results after a few recallibration. The Fabscan shows that the callibration worked and i`ve followed the instructions of AndreaCH,in the other discussion about callibration, but my scanning results were not so good. Here is a picture of one of my results  .html

And here is my default.config

Maybe you have an idea what i can do to get better results.

There wen something wrong with the picture so here is it again: https://ibb.co/WnPZwkN

Hey guys,

Its been a while, but i did not get to manage this thing. I couldn`t get a callibration for the scanner. The scanner hangs up after the first rotation to the side and it shows the window ''the FabScanPi server is not available''. The problem therfore is that after that and restarting the scanner there isnt a file in the log. I`m using a the 0.7.0 version, a watterrot set with stepper motor 17HM3410 nr 20170821 and a rasperry pi 3 model b. Everytime i want to calibrate this thing it shuts down.

i think the problem is not the Software. you have cold solder joint. check this

So thanks a lot for the help. Now it works, but it wasn´t one problem alone. So first of all i checked all solder joints. They were good, so i decided to test other things. The next thing ich checked was the reference voltage of the driver and set it to 0.8 V after that the motor itself works, but the server crashes didnt stop. I read in one of the old forums about the that the Raspberry 3 model b has difficulties with power so i decided to use a labour power adapter and with that i saw that there was a drop in the ampere rate after a time and following a freeze of the system. So i decided to change the raspberry to a model 2 and after that everything, the callibration and some scanns worked.

So thank you all for the help :)

how would i remove the stepdown converter? just unsolderit or do i have to remove something else?
