Cannot Update Camera Calibration Image

This is my biggest problem, I’ve managed to overcome or work around most other issues but this one is a show stopper.

The image used to calibrate the Laser module camera will not update. My initial calibration image taken on first use of the machine was on a white piece of paper, it’s impossible to see the lines on this because there is too much reflected light so impossible to calibrate (fails both automatically and manually).

Since then I’ve tried using some less reflective materials for the calibration process but the image that is stored in the machine’s memory will not update.

Example:
I’ve just run the calibration process on this piece of cardboard:

But when I go to the Calibration screen in Luban the image shown is still the same white piece of paper I used for the first calibration. See next post as I’m a new user it won’t let me put two images in a single post.

I’ve repeated this many times with no success. Do I have a defective unit?

I’ve now tried clearing the control module memory and factory resetting the controller. Still the same issue, the calibration image never updates.

Hello, I know your problem is a long time ago, but I have been struggling with this problem for almost two years and now I finally have a solution. If you or anyone else has the same problem, I’m happy to answer and help here.

Why not share right now? You could even open your own topic if it’s not exactly the same issue.
This could help the next one :wink:

@xchrisd sorry, It was too late for me to write an explanation yesterday, although I’ve just realized that it’s actually a minor thing. I had in the back of my mind that it took almost 2 years for support and I to find a solution.

So, to the problem. I also cut and calibrated a calibration sheet and then I wanted to display the current part that was on the table in Luban, but that didn’t work. The loading circle was displayed endlessly. Every attempt to restart the installation of the laser ended with me apparently being shown an old version of the calibration sheet from the cache.

After resetting, the recording for calibration worked again but no longer. Since it worked and was also displayed to me in Luban, it was assumed that the camera and the WiFi connection seemed to be working.

But that wasn’t the case. After I replaced all the components (Bluetooth antenna, camera and the entire circuit board) of the laser module and then finally the entire module, we tested the camera using the developer console and everything worked up to the Artisan monitor, but not up to Luban.
The solution was that I had to create a hotspot with my cell phone in the 2.4 GHz WiFi and then log into this hotspot with the Artisan and a laptop. That worked. Apparently due to the mesh function of the Fritzbox, the devices switched between the 2.4 and 5 networks. Since my printer is one floor above my PC, the 2.4 signal is slower but more stable.

I hope I was able to help someone with this. :slight_smile:

For those that aren’t aware, a Fritzbox is a modem router.
Some wifi routers combine the 2.4/5 into one SSID (the transmission name). The person receiving has no idea or choice as to which they are using.
In many router settings it’s possible to split the SSID into separate SSIDs. Then you can connect to one of them and stop the receiving device from switching.
