Yes, with the Dec. Address of 39 it works.
I'm sorry. I dont know why i didn't see the missing comma. It works everything perfect if the syntax is the right one.
The only printed Label i cold find is 1602A on the backside.
Teh display looks exaclty like on this one "http://www.aliexpress.com/item/1602A-LC … 52414.html" diferent is just the i2c module.
it is a "pcf8574t" i2c controller
Adress 32 does also not work and the command "i2cdetect -y 1" gives the following result:
0 1 2 3 4 5 6 7 8 9 a b c d e f

The Test Python Prog i use is: "wget https://bitbucket.org/MattHawkinsUK/rpispy-misc/raw/master/python/lcd_i2c.py"
The only enabled Setting in config.txt are:
dtparam=audio=on
start_x=1
gpu_mem=128
dtparam=i2c_arm=on
disable_camera_led=1
hdmi_pixel_encoding=2
dtparam=i2c1=on
and the Blacklist is empty
Yes i can share the Profile.json.

Yes, the Camera is enabled. It runs over the commandline with as example "raspistill -vf -hf -o cam2.jpg". Also it takes images by printing every layer. But it makes no Image by pressing the "Take Photo" button.
Pressing the "Take Photo" Button does not makes any photos. The kind of setting (manually, every layer, every 2 layers, ...) does not have any effect for taking a manual Photo.
Tested with Build 1074
The Export for the Profile works well. But if i'll import the Profile, the webpage keeps standing on a blank importpage and the Profile get not imported. No change if the ID is used in the Database or not, also not if there is no profile present.

Does someone have a tip how to get the I2C Display running. I alway get the message "Could not access LCD write /dev/i2c-1: input/output error". chmod 777 on the file does not make any changes.
I do using this "http://www.sainsmart.com/new-sainsmart- … ga-r3.html" LCD witch is running on Port 27.
With the Python test Prog at commandline i'll get the correct display on the LCD.
I will post a new topic for calibration feature shortly. To get feedbacks.
Cool, great. Let me know if and what i can test for you.
Shahin,
I fully agree with your way for the calibration. It's a little more complicated but will work also. And i can live with this two ways (your's and my one) very good.
Usually you print just one frame or you need whole cube to be printed?
For me i just need only one layer to do the calibration
Yes, i think its the moste easy way because of the resizing.
What i'm doing to Calibrate:
1. Upload a part with size 100mmx40mmx10mm as a plate
2. Turning the first layer to 30sec.
3. Lift the z-axis to have free access to the printing bottom
4. start print toshow the first layer
5. no i can easy meassuring the size as example 106.3mm with a paper ruler
I know that it have to be 100mm in lenght. now i can calculate the new xy resolution.
as example i had 70.45 microns for 100mm and my meassuring was 106.3mm. now i can calculate the new microns (70.45/100*106.3=74.41)
6. now i have to delete the plate and start again by point 1 if the size is not as good as it shold
To start printing i think is not so exciting to can meassure the size of the image. An start a normal print with resin is also no a good option for me.
The best an most luxury way is in my opinion:
To shorten this way aboth as example set the new x/y resolution and send the image to the projector without uploading as a new plate thats will be great.
For backup the profile it will be cool if there is a button to Import/Export Profiles. It's more user friendly than connect with ssh and copy back and a lot of users are not familiar with linux.
Send a Layer to the Projector from the Plate Site. As example you can now show the layers on th webform a button with called sent to projector or something like this will help to calibrate the projector. I very often makes a Print with a 100x40x10 (LxWxH) and displays on the Projector. now you can measure the size more easy and set the correct parameters on the calibration settings.
