Edgar Huckert: 3D Printer

I use a 3D printer type MK3S from Prusa.

I have written my program 3DPrinterComm.c to understand how the communication with this printer works. This program has been designed for this printer only. I think however that it can be applied (with some modifications) to other 3D printers also.

Note the following remarks and restrictions:

• This is a command line program written in standard C. See the comments for compilation and execution hints
• Works only under Linux
• Assumes connection over a serial line (simulated via USB)
• Assums a baud rate of 115200 - you can change that in the program
• The device /dev/ttyACM0can also be named differently. Be sure that this (or a similar) device exists

A different (and simpler) method to find out how the communication works is the use of a typical modem program. I used minicom (must probably be installed with apt-get) with success:  
     sudo minicom -b 115200 -D /dev/tty/ACM0 -L -C /tmp/3D.txt  
It may be necessary to turn local echo on and to add LF after CR in minicom.
