I wanted to flash one of my other two Uno's with grbl, but they're both giving me the below errors from the Arduino IDE.  Note that if I reflash the Arduino that came with the x-carve, it works.  But doesn't fix the problem.  The problem, if you're wondering, is that the limit switches worked for one day, then sort of 'just stopped'.  Checking the voltage on the arduino pins for those switches, they always read 0v.  So I wanted to plug the gshield into another Arduino to see if it gives me the same results, but... no flash :(\r\n\r\navrdude: stk500_paged_write(): (a) protocol error, expect=0x14, resp=0x0d\r\navrdude: stk500_cmd(): programmer is out of sync\r\nAnd sometimes this:\r\navrdude: stk500_recv(): programmer is not responding\r\n\r\nThe only difference is that the uno that came with the x-carve has the 'small chip' on it, while the other two I have both have the bigger caterpillars soldered to it.  The chipset is the same though, 328p.\r\n\r\nAny thoughts?  Since I'm on mac, I also tried the hexuploader, but I couldn't get it to work for *any* of the arduinos, I'd usually gave me the bottom error.\r\n\r\nThanks"},"comment":{"url":"https://api.github.com/repos/grbl/grbl/issues/comments/168540020","html_url":"https://github.com/grbl/grbl/issues/874#issuecomment-168540020","issue_url":"https://api.github.com/repos/grbl/grbl/issues/874","id":168540020,"user":{"login":"kosme","id":1418331,"avatar_url":"https://avatars.githubusercontent.com/u/1418331?v=3","gravatar_id":"","url":"https://api.github.com/users/kosme","html_url":"https://github.com/kosme","followers_url":"https://api.github.com/users/kosme/followers","following_url":"https://api.github.com/users/kosme/following{/other_user}","gists_url":"https://api.github.com/users/kosme/gists{/gist_id}","starred_url":"https://api.github.com/users/kosme/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/kosme/subscriptions","organizations_url":"https://api.github.com/users/kosme/orgs","repos_url":"https://api.github.com/users/kosme/repos","events_url":"https://api.github.com/users/kosme/events{/privacy}","received_events_url":"https://api.github.com/users/kosme/received_events","type":"User","site_admin":false},"created_at":"2016-01-03T20:50:58Z","updated_at":"2016-01-03T20:50:58Z","body":"Without any more information, it seems like you are selecting the wrong port.
