I then looked at the buffer size, and increased it to 512, and everything worked ok. i send several tx "OK." acknowledge commands back to reprap. tx was barely even on! - so i tried something. i hooked up an oscope and checked my signals, and checked the rx and tx signals. I've worked on the arduino for optimization and still have had slow speeds. #Gcode art of illusion software#I accidentally fixed this from my latest released software version, but will need to change it to do better buffering, so will implement the serial alternative. that will speed up the arduino immensely, and stop the sudden pauses that bind the threaded rod system, and slow down my pull chain version of my reprap. The partial answer is to now move the serial communication over to an alternative, that allows buffering of send data, sending data while receiving data, and multiple tasking and interruption of most of the routine during send data except for output mode change. the arduino is not capable of buffering output data like it is on input data! In fact the arduino stops doing anything else while sending data. then i looked up the arduino uart system, and finally it hit. Also this meant that i was sending the oks at gcode processing time, and that except for the very 1st gcode line, the acknowledgment was sent when the next command was in process, and the buffer was full, so it was not done when the calculations and movements were performed, but in between.Įureka! i dived into the code, and sure enough after enabling 4 buffers again had timing issues with the threaded rod design. looking into this further, one of the changes i had implemented was reducing the line buffer from 4 commands to 2 commands, and increased the serial data buffer, and sent multiple oks back to host to receive more than one line of gcode data at a time. my last tweak to improve the performance of the sending of commands to arduino from host accidentally gave me a clue as to why performance was just not faster from sending data over buffer more than one line at a time, but it was also not missing steps. I have used the reprap 5d code, and had been tweaking it for some time. it just did not make sense as to why it was loosing steps and also communicating so slowly.
