I need to set the HOME_POS manually since it isn't printing in the center of the bed. But whenever I try to upload it to the Melzi 2.0 board I get an out of sync error.

I am using Arduino IDE on Manjaro Linux, I was able to upload Marlin to the board on Windows 10 but I have since removed that OS. I have the correct settings for the board: Sanguino Atmega 1280 or 1280P (16mhz)

Here is what I have tried to get me this far:

  • Running Arduino IDE as root (administrator) which fixed the permission denied error
  • Changing the Board and the processor settings
  • Uploading a fresh Marlin firmware with no changes
  • Uploading a simple program to my Arduino UNO which worked
  • Changing USB Ports (USB 3.0, USB 2.0)
  • Changing the Baud Rate from 115200 to 57600

Here is the (verbose) error message

  • have you tried installing via ISP pins? – Trish Jul 14 '20 at 06:14
  • So it was already running Marlin (uploaded from Win10)? You could have used [`M206`](https://reprap.org/wiki/G-code#M206:_Offset_axes) to change the offsets instead of uploading a completely new firmware. On topic, this is a very common and generic error message, a troubleshooting answer can be found [here](https://arduino.stackexchange.com/a/18/52058). – 0scar Jul 14 '20 at 06:29
  • Your board might be using the old bootloader which needs a 57600 baud rate for uploading instead of the default 115200. You'd need to modify that in the respective boards.txt – towe Jul 14 '20 at 06:47

    @towe I tried that it did not work ( I added it to the question now to help narrow it down) – Bodhi Teraguchi Jul 15 '20 at 03:02
  • That's odd. Enable "Show verbose output during: ... upload" in your IDEs settings please. That should give you the avrdude line the IDE uses to try to upload to the board. – towe Jul 15 '20 at 06:09
  • I found a suggestion on the Arduino stackexchange that you remove any shields or anything connecting digital pins 0 and 1. The error you're getting is a connection error and could mean any of a thousand things. Can you do as @towe suggested and enable verbose output? – Nach0z Jul 15 '20 at 14:45
  • @towe there you go :) – Bodhi Teraguchi Jul 16 '20 at 01:00
  • @towe i needed to change it in the serial monitor as well thanks! – Bodhi Teraguchi Jul 16 '20 at 02:34

Okay thanks to @towe for helping me I figured it out. my Baud Rate was set to 115200 but my board is using the old bootloader so it needed to be 57600. I Changed my boards.txt file to that but the verbose console printed: Overriding Baud Rate : 115200 turns out you need to change it in the serial monitor as well (the little magnifying glass in the top corner of the IDE) after that everything worked great thanks for all the help!
