I'm able to upload GRBL in the arduino but i don't know if I can find a way to configure it. I'm using a 42byghw609 stepper motor .\r\nThis is my configuration:\r\n\r\n![img_20160427_150429](https://cloud.githubusercontent.com/assets/18011231/14853590/743e6774-0c8c-11e6-83a4-bdcaeec54a6e.jpg)\r\n\r\nIt is possible to use GRBL with this config ? What config did i need to put to make it work ?\r\nI've made some test and i can only make the motor turn a little bit before having an error : \r\n\r\n![image](https://cloud.githubusercontent.com/assets/18011231/14853534/30fd41a6-0c8c-11e6-90ea-5e2b3a8074ab.png)\r\n\r\nThanks for your help ( sorry for my english, it's not my main language )"},"comment":{"url":"https://api.github.com/repos/grbl/grbl/issues/comments/215093518","html_url":"https://github.com/grbl/grbl/issues/977#issuecomment-215093518","issue_url":"https://api.github.com/repos/grbl/grbl/issues/977","id":215093518,"user":{"login":"electrokean","id":2536210,"avatar_url":"https://avatars.githubusercontent.com/u/2536210?v=3","gravatar_id":"","url":"https://api.github.com/users/electrokean","html_url":"https://github.com/electrokean","followers_url":"https://api.github.com/users/electrokean/followers","following_url":"https://api.github.com/users/electrokean/following{/other_user}","gists_url":"https://api.github.com/users/electrokean/gists{/gist_id}","starred_url":"https://api.github.com/users/electrokean/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/electrokean/subscriptions","organizations_url":"https://api.github.com/users/electrokean/orgs","repos_url":"https://api.github.com/users/electrokean/repos","events_url":"https://api.github.com/users/electrokean/events{/privacy}","received_events_url":"https://api.github.com/users/electrokean/received_events","type":"User","site_admin":false},"created_at":"2016-04-27T14:03:38Z","updated_at":"2016-04-27T14:03:38Z","body":"Oh, and you appear only providing power via USB.  That wouldn't work for driving a stepper motor which will need more power (voltage & current) than USB can provide."}}
