I am using a Raspberry Pi 3 model B with the 7" touch screen display to send G-code to a TinyG control system. I have no experience with Raspberry Pi's or Linux, so this is all new stuff to me! I need to send G-code files to a TinyG controller that runs a robotic seal maker, and I am having some trouble getting the G-code to send. The seal maker currently uses a windows PC running CoolTerm to send the G-code, but CoolTerm will not work on a Raspberry Pi due to its Arm architecture.
I have found this resource: http://www.forkrobotics.com/2013/07/usi ... -shapeoko/ which explains how to send G-code using Putty and Plink. I have installed both of those onto the Raspberry Pi, and I have verified that the Raspberry Pi is reading the TinyG via the 'lsusb' command. If I am understanding correctly, I don't need to install the FTDI drivers as they are already on the Raspberry Pi.
From the link posted above, it looks like I can use the command 'cat test.txt | plink -serial /dev/ttyUSB0 -sercfg 115200,8,n,1,X' , where test.txt is a text file of G-code on the Desktop. When I run this command, there is a 'no such directory or file' error. I'm sure it is something very easy, but I can't seem to figure out what the problem is. Any help is appreciated!
