Hi Try download and use Arduino version 21. Had smilair problems compiling the extruder firmware on version 22. /Daryby DARY - Reprappers
It works again. By seetting the baudrate of COM port in windows settings to 57600 and in the board.txt for Sanguino to 38400. Don't ask me why. I neither have to touch the resetbutton at all. Over and out DARYby DARY - Sanguino(lolu)
Okay. The problems are back. I can't upload to the board again. The only thing i have done is updating Java, which was necessary to run the RepRap software. The software perfectly communicate with the board - making one of the stepper motors spin. This means the board works, the wiring are okay and the USBtoRS232 is okay. So why I can't upload is the question. This is my currently configuration:by DARY - Sanguino(lolu)
Hi I managed to download the program. That is the positive side, but the negative is I don't know how and why. I tried to make and use a RS232 cable connected directly to the pc's com port. That gave the exact same result with the constant light on debug led. Then I just wanted to give another shot with the USBtoRS232 adapter - checking the wires and so. First try downloading succeeded - even wiby DARY - Sanguino(lolu)
Thanks. I will try do this later today. Besides that I have an old laptop with serial com port. I will try this if nothing else works, to skip the USBtoRS232 module. DARYby DARY - Sanguino(lolu)
Hi Viktor But the reset trick might be used on the extruder board while downloading aswell? I have tried Arduino-18, -19 and -20. Same issue with all of the. Maybe I should try downloading the software again, to go back to original settings in the boardfile. DARYby DARY - Sanguino(lolu)
Thank you for the responses. Unfortunately nothing works. I flipped the TxD/RxD, with only result that the debug blinks in a different way. No constant light on. I cannot program the extruderboard either. Here the debug led doesn't blinks at all when uploading - only the 1 second on / 1second off which showing the bootloader is in the chip. My only conclusion for this. There is something wrong wby DARY - Sanguino(lolu)
Hi I have the 6-pin USBtoRS232 adapter from FTDI which was recommended in the Reprap Wiki. Okay so all you use for the 4 wire is(on the motherboard): 2 = GND 3 = VCC 4 = RX 5 = TX ?? BTW the pin 1 and 2 are physically connected on the PCB, so it doesn't matter which one to use for GND. Thats why I was curious about the #CTS connected to pin 2 in the diagram. No haven't try to reverse - but wby DARY - Sanguino(lolu)
Hi Thanks for the response. Well, actually didn't try uploading to the extruder yet - but as mentioned tried 2 different motherboards. I am curious about the debug led. When you had the problem uploading - did yours aswell blink and then light up constantly? Also a little curious about the wires connection 2(#CTS). On the Motherboard it is connected to ground - is that right or at least needed?by DARY - Sanguino(lolu)
Hi I seriously need some help. When uploading to motherboard I get the well known: avrdude: stk500_getsync(): not in sync: resp=0x00 avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51. I have tried everything sugested - here and on the arduino forum. This means: - The reset trick. Pushing reset before, after while uploading to board. - Changing settings for the com port and inby DARY - Sanguino(lolu)
