Posted by: @moop I recieved an email from Watterott today with notice that they are sending me a new PI HAT: Glad to hear that.

Posted by: @trife Is that using an Arduino? Does not matter what you connect at the other end. This solution fits both. Pi and Arduino. But in my case i am using a real isp programmer with a 10 pin...

Just added some pics of my self made flashing tool.

Just want to show my solution for flashing the Bootloader, if it is necessary. I used a piece of prototyping pcb some pin headers and a piece of a croco clamp. The clamp is used to connect the reset p...

Posted by: @trife after dumping hundreds of bucks with custom fees and import fees to source this stuff it would be nice to get it working and figuring out why they are dead out of the package i susp...

I think we should stop double posting this issue in two languages. I suggest to solve this in the german thread and when we found the solution we will also post the solution in english here.

Welchen Browser verwendet du? Kannst du mal deine Kalibrierungs Werte aus der Konfiguration hier posten?

I will try to do some documentation on how to setup a dev environment this weekend. But do not invest too much time in the Frontend because we are working on a new Frontend based on Typescript and Ang...

Posted by: @moop "Serial read timeout occured, skipping current and waiting for next command" I think you can ignore it for the first steps. This is more a warning than a real error. I already chang...

Glad to hear. So i will mark this as solved.

I think a combination of the current calibration mount and one of the shown solutions would be very nice.

Posted by: @moop It seems the pivot point for all three positions needs to be the same. I am not sure. For the laser calibration step (second turn) it needs to be the same. But for the first step is...

Posted by: @aduda For general camera calibration I wrote an article about it . Thank you for sharing this! I will give it a try.

Die Kalibrierung sieht so weit gut aus. Deshalb gehe ich davon aus das der Scan auch durchlaufen würde. In geringster Auflösung dauert der Scan ca zwischen 20 bis 25 min. Dein Problem scheint "ledigl...

Posted by: @moop Thank you for the quick response. The laser does come on when I powerup the fabscanpi, and "When the settings are avaliable" I can turn it on and off, as well as rotate the turntable...

It is explained on this topic:

This is a well known issue. The rotation value leads to an error. I will try to fix that within the upcoming release. There is already an issue on GitHub:

My tip. Your motor is doing two turns. If you are using the silent step stick motor driver which is delivered with the kit I will bet you are using a motor with 200 steps and your configuration is set...

It should run with those drivers. But when it is running you need to do some additional tweaks on the HAT. (see ) Let's solve things one after the other. We should start with the motor. Can you post t...

You are able to use two lasers and you are also able to use the same laser color. But at the moment there is no option to use a different color for each. It needs to be done in Software. If you want t...

Unterschiedlich. Du kannst den Lüfter entweder mit 5V oder aber mit 12V betreiben. Da das HAT überbestückt ist, da ja noch Platz für weitere Motoren ist kannst du die Spannung an dort abgreifen. Löte ...

I am missing the most important part of the calibration section. Try to use cat /etc/fabscanpi/default.config.json That will output the whole config in the terminal and that is the best way to copy a...

Generell ist es für die ersten Versuche ganz gut erst einmal ohne Farbe/Textur mit der niedrigsten Auflösung zu starten. Das läuft in der aktuellen Version (0.8.2) dann ca 20 min. In der nächsten Vers...

Sounds great. Can you give us some updates?

Can you please share some pictures of your wiring? It is unlikely that the motor is dead. Those errors are mostly caused by one of these issues: wrong wiring bad solder joints corrupt motor driver w...

Can you share your calibration values. You can find them in: /etc/fabscanpi/default.config.json

So hier mal kurz meine derzeitige Messung bei Scans ohne Textur/Farbe, nur Objekt: Auflösung Zeit Bilder/Laser 10 % 5 min. (800 Bilder bei 2 Lasern) 100 % ...

Cool! Später bitte Bilder von der Konstruktion! ?

@danilo0702 Läuft der Scan denn wieder durch?

Posted by: @danilo0702 Filezilla Sure. Exactly what i meant. ProFTPD is a Server. My mistake.

Posted by: @mcinerney Can you please tell me what software package you are using (Shown in your post)? Looks like ProFTP.

Der letzte aktuelle Log ist immer der wo keine Zahl dran hängt. Die Logs werden rotiert. Ich glaube nach Datei Größe. Das heisst soviel wie wenn die aktuelle fabscanpi.log eine gewisse größe erreicht ...

Ohne Log ausgaben ist es schwer bis gar nicht einzuschätzen was da vor sich geht. Posted by: @danilo0702 Nun habe ich die 0.8.2 installiert und kein Scan will mehr nach einem update heute richtig ...

@Hamishi Just created a new topic for this, because this is not related to the faq topic anymore. ;-)

@hamishi Thank you for your work! I will add this to the documentation as soon as i can. I think i will find some time at the weekeend.

Posted by: @hamishi Can you confirm, that these pins are not driven by the software. Yes. The driver configuration is not software driven. Only hardware. The pads are not connected by default. So th...

Just ordered some 2208 drivers from watterott.

OPEN != GND I don't know what happens to the 2208 when those config pins are OPEN. This state is not defined. Here is the TMC Datasheet. FYI here is the schematic of the HAT As far as i know is the ...

It seems that newer kits are delivered with the tmc2208 now. I will have a closer look to it and try to reproduce this by testing a tmc2208 in my setup. 12800 steps doesn't make sense. A scan in a low...

I have no idea. But if it is a 400 step motor your driver is making 1/32 steps. In case of a 200 step motor it is making 1/64 steps. Both values are possible with different types of the Tmc drivers. W...

Posted by: @hamishi GO[T(400)] G0 T400

@hamishi Exactly what i came up with a couple of minutes ago, but you were faster :) The default driver delivered with the kit should be the TMC 2100. The default config for the 400 steps stepper is s...

Normaler FabScan oder Ciclop? Kannst du die letzten Zeilen des Log files posten wenn das passiert?

Kannst du mal deine Konfiguration posten? Also die /etc/fabscanpi/default.config.json

I think i had a similar issue. But that was not related to the events. It was a serial bug. After sending the command to the firmware, the firmware will send an ack ( think it simply echos the command...

Thank you for reporting this issue. Is your scanner connected to the internet? Another workaround would be to change "discoverable": "True", to "discoverable": "False" in the config. That prevents t...

Posted by: @jwalt Yes, that's what I meant. I double checked that every single point you mention is true. Any remaining deviation was way below 1mm, not noticeable to the naked eye. A second calibrat...

Posted by: @jwalt Today I added a second laser to my Fabscan Pi, and I am getting wrong results. The scan from the first laser is about 10% smaller in the X and Y dimension than the scan from the sec...

You need to bridge the safety switch connector. See Section "Connecting the Lasers"

Try to use the non-automatic threshold setting and increase the threshold by shifting the slider to the right side. Have a look on the laser line detection. By the way, black can also cause problems ...

Can you post a picture of the object please. I would bet that the top of the object is transparent or reflective (maybe a shiny white surface)? You can try to deactivate auto threshold in the settings...

Is it a TMC2100 or TMC2130? I don't have that much experience with the TMC2130. But check if you wired the motor in a correct way. It is important that you have wired it like it is described in the do...
