Have experienced problems connect to my Mendel 90 printer from pronterface, and to upload from arduino.
problem started om my Kubuntu machine. I found and fixed some software corruption and after manually unmarked and rename some lines in melzi/cores/arduino/main.cpp ; /marlin/SdBaseFile.h and /marlin/SdBaseFile.h that gave error massages in Arduino. After that I was able to upload the sketch. After that the connection from pronterface whas gone. changing back all modification made no difference.
Now I tried my Debian machine that has worked for years. Immediately Arduino complained about the same SdBaseFile.h, after unmarking all upload worked ( no problem with the marlin files.)
since I have'nt used this computer until now, I wonder where the problem is. Could it have something to do with the latest uploaded sketch?
I checked usb connection with dmesg and found this line for the printer connection
[ 452.802707] Thread-39[2236]: segfault at 7f2c2803b100 ip 00007f2be66e3261 sp 00007f2c0cb57248 error 4
everything else looked normal.
Without pronterface my printer become useless so this is a serious problem. Tips and help would be more than welcome.
