I am not at Home at the moment. I will have a woking FabScan available on new years eve. So i am able to test my fix in a working setup. After a a final test in a fully functional FabScanPi, i will re...

I think it is the same bug as many people have by using the current version (0.8.0). See for further information. Have a closer look to my latest post in this thread.

This is for all people who want to test the ciclop compatibility. Here are some pictures of how i added the raspberry pi to my ciclop. Attachment : IMG_20190618_202337.jpg Attachment : IMG_...

It is solved. Have a look to the thread in my previous post.

Have you already tried to flash with your 57600 baud?

A temporary solution (until the bug fix release is finished) can be found here:

A temporary solution (until the bug fix release is finished) can be found here:

There is also a bug report on GitHub for this issue. I am just trying to find out if my fix works for all of you.

@mcinerney Ok. As next step we will try to flash the latest fabscan firmware manually: sudo /etc/init.d/fabscanpi-server stopsudo avrdude-autoreset -D -V -U flash:w:/usr/lib/python2.7/dist-packages/f...

Hi everyone, i had some time for testing. I flashed my HAT to get in an initial state. Afterwards i run into the same error. But i think i have also found a solution. Please try the following and giv...

This is a maybe a bug related to the current software release. I am working on a fix. You can follow one of the other topics related to this issue:

@justinb @mcinerney I have an idea on what is going on. I think that the FabScanPi Software runs into a deadlock while it tries to install the firmware when the HAT is a new one with only the boot loa...

@justinb sorry for not responding earlier to your posts. I am doing this project mostly by night after my day job. In general those HATs are nothing else then arduinos which you can stick on the pi. I...

@mcinerney I think in his case the solder joints are the problem. In your case we need to go deeper. Have a look at my latest reply:

Of course. That was my fault. The serial port is blocked when the Server is running. But it is good to see that the serial connection is working. Now we can be sure that the HAT is ok so far. I think ...

Ok. It is time to discover what is going wrong. First we need to find out if the HAT is able to communicate with the Raspberry Pi. For this you can try the following command after you are logged in on...

Sorry but I think the user who made this video is blocked by youtube.

Posted by: @lre It seems that the page at no longer exist. Should we use instead? Yes. Thank you for the hint. I updated the links in the post.

Das stimmt. Ich werde die Doku noch einmal überprüfen.

Läuft der Scanner jetzt ?

Seems to be a problem with serial connection to the Pi HAT. Try the following:

Ich habe aus der alten Doku den Punkt zum flashen noch mal überarbeitet und in die F.A.Q unter Hardware hinzugefügt.

I have added a new topic to the hardware F.A.Q. I hope this helps you. If it works, please prevent this issue by using the new image version. Because 0.7.0 can cause this issue.

If you are have the Message "No FabScanPi HAT or compatible device found" in your log file you need to check the following options. First double check the solder joints of the 40-pin Header of the Fa...

Kannst du mal den Bootloader flashen und die neue Release (v.0.8.0) testen. Damit sollte der Fehler eigentlich behoben sein.

Problem gelöst?

The kit is delivered with a 1 mW laser, because a lot of schools asked for a 1 mW laser instead of 5 mW (safety precautions). But a 5 mW will also be fine.

Closed because of double post:

Or just as @danilo0702 suggested increase the amount of steps for turntable. Just double it. But keep in mind that will not increase the scan quality.

Do you want to rotate two times, because you expect better scan results? If so i can say that you will get the same pointcloud twice. If you need it for a custom project, you need to change stuff in t...

Does the FabScan software provide a feature to use laser movement with a servo or stepper motor, cause the case provides some options to mount a servo or stepper.

Which type of LED Ring is supported by the FabScan Software yet?

Do i need the LED light for scanning or calibraion?

I have a Raspberry Cam Module with NoIR. Can I use it with the FabScan software?

There are several cameras out for the Raspberry Pi. Which one does actually work with the FabScan?

It should move clockwise – if not please consult the hardware chapter of our documentation and check the connection of your stepper.

Do i need a special power supply for the FabScan?

You need to know the number of the older version you want to step back to (e.g.: 0.4.0-b373) : Open a console (or remote ssh-console). Type in: sudo apt-get install fabscanpi-server=0.4.0-b373 Follow ...

I need to stop/start/restart the server manually how can i do that?

How can i have a closer look into the log files?​

I need to find out what my scanner is doing or not. So where can i find the log file of the FabSanPi Server?

You can find it in the folder: /etc/fabscanpi The config file is named : default.settings.json

You can find it in the folder: /etc/fabscanpi The config file is named : default.config.json

The laser and the LED-light are needed for the calibration, they must be installed and be able to work. Make sure the box is closed during calibration so that no external light can cause problems.

No, the calibration data will be stored. We recommend to perform a calibration every time when the FabScanPi has been shipped, modified or the scan results show signs of deformation.

I need to connect to the Raspberry pi via ssh connection. What are the credentials?
