Got it going! Turns out that when the erase button is pressed, the USB port reverts to COM7 (on my PC). I ran bossac through COM7 and had successful upload. When the CPU auto resets, the port changes back to COM6. I can now communicate through Pronterface and Arduino. Now to complete commissioning. Thanks very much for your help. MikeLby MikeL - Ormerod
Thanks for the replies. I have confirmed COM6 (though I did see the driver allocated to COM7 very early on), and that RepRapFirmware.bin is in the same folder where I started bossac. Yes - I should have said M503 was the code sent via Arduino. I should also mention that any time I try to download Arduino 1.5.5 I only get 512kb of the specified 66.3Mb download. So I installed Arduino 1.0.5by MikeL - Ormerod
Hi Folks I am having trouble commissioning my Ormerod. I have installed the driver (COM6) and can run Pronterface, but when I try to connect (USB cable and SD card fitted) I only get "Connecting..." I can run Arduino 1.5.5 and connect to COM6, but get no response when I send M305 or the like. What I have read seems to indicate that I have lost the built in firmware, so I tried to use bossac to reby MikeL - Ormerod
