overflow and bad communication, i suppose... #22

Hi thunderbug, i'm facing some problems, i don't know what's wrong. I've downloaded everything, i've uploaded the arduino code with some warnings (see below) but no errors. I've modified the config.h (i will copypaste it below) and the servo is ok but the stepper don't work. I don't think that's a motor/driver problem, they used to work last time i checked. I can connect the spherebot control 2.0 to the arduino, i've tried to send the example gcode inkscape-unicorn.gcode that i've found but i see a very slow communication in the two boxes in the control software, transcieved data and received data. Just to give some numbers, a new line appears once every 3-5 seconds, only for the first 5-6 lines and no more lines after that, and an "Overflow Error" appears once on the received data box. If i use the serial terminal in the arduino ide i can move the servo and i have a fast response, i'm trying to move the steppers but i cant actually control them properly. Anyway, my opinion is that the problem is related to the control software but i don't know how to check that.

I'm using a windows 7 pc and an arduino 2009 wiht the 1.6.5 ide, this are the warning that i see when i upload the code and my config.h.

Thanks for the help!

yes the problem lies probably on the control sofware side. There is a nasty bug I couldn´t find so far.

It is programmed to resend the command after some seconds if no "ok" was received as an answer. Probably this goes on until the receive buffer of the arduino overflows. I implemented this resending as sometimes the print just stoped.

Thank you for the reply. Any chance that this bug will be chased in the near future? I've tried to send commands over a serial monitor and the firmware seems to be ok, the unikorn plug in is working, but i can't figure out how to deal with the host-gui. It's a pity, it's the most updated and complete project i've seen...

i'm available as beta tester, if needed! :)

I think I have found the bug and updated the code.

Hi thunderbug1,

I'm facing the exact same problem as marcogarzotti. I downloaded everything today, so I still think there is a problem.

When I use the arduino serial monitor I can send commands with quick response. Also with putty I can send all gcode from a file and get fast response (I don't know if it runs the file till the bottom)

Could you have another look at the software, because I really like your work and I'd like to use it.
