Read data from Ultimaker

[sergii 0]

Hello community!

we have just received and assembled a wonderful Ultimaker Original + and now busy playing around.

Later we want to monitor all the data on our printer: the temperatures, the coordinates of the head, the velocity, etc.

What is the best way to access this data? Is it possible to ask Cura for this data stream? It would be even better to be able to place a small programm on the board, which would then read the data and push it back to the computer somehow.

I am sure someone must have done something like this already.

Looking forward to your responses.

There is a lot of software out there that operates as a "3D printer host".

When not printing from an SD card, the host must feed the g-code in a certain way with checksums and resends. As part of this stream, you can get the temperature info back.

The head position can be implied from the g-code as it is sent. However, the accuracy of the g-code coordinates is limited by buffering done by the FW. If you send "go to 0,0,0", the printer may accept it immediately. Because you just sent 0,0,0, you report the head as 0,0,0, but the command might be bufferred and there may be some "slop" in time before the FW actually gets to 0,0,0.

When you print from Cura, it operates as a host as does Simply3D (which also pseudo reports the head position)

You might look at http://www.pronterface.com/index.html . It is an open source 3d printer host and UI with a command line host too. If it doesn't do what you need, at least the source code can guide you on how to make mods.
