Yes, I ordered the Smoothieboard from Robot Seed. This is the board I have: http://robotseed.com/index.php?id_product=101&controller=product&id_lang=2. I use external drivers, therefor I ordered the 0X version. Just to be sure, is it the EN1, DIR1 and ST1 that is used for the X-axis and EN2, DIR2 and ST2 for the Y-axis?
I have removed the smoothieboard from the laser cutter and tried using Putty with several baud rates, but could not receive or send any commands or information. I also tried to use smoothieboard’s independent serial (UART) port, with a serial to USB adapter, like it is described here: http://smoothieware.org/uart, but the result where the same.
When I uploaded Smoothieware to the SD-card, I received the message:
At this point, I could also send commands to the board, and the LED nr.1, 4 and “3.3V” on the board where constantly on, while LED nr. 2 and 3 where flashing. When I uploaded GRBL-LPC firmware, the only LED that was on, where the one labeled “3.3V”. (during the hole period, the only power supply I used, where my computer through the USB-cable. I tried to use different USB-cables)
I concluded that something must go wrong when I flash the program. I believe that the bootloader recognizes the firmware.bin file, because also this time the .bin file where renamed when I looked at it, but I absolutely do not know what causing this flashing-issue. Do you have any recommendation for how I should proceed the troubleshooting?
