My Z axis is a solenoid. I was trying to use the Z Dir pin to control it, but this doesn't work well. It goes down OK with a -Z command, but as soon as the next XY command is sent it goes back up. The sender still thinks it is negative however. \r\nIs there away setting that can be configured to make the Z direction pin ( or another pin) behave this way?\r\nThanks,"},"comment":{"url":"https://api.github.com/repos/grbl/grbl/issues/comments/214292666","html_url":"https://github.com/grbl/grbl/issues/883#issuecomment-214292666","issue_url":"https://api.github.com/repos/grbl/grbl/issues/883","id":214292666,"user":{"login":"djowen40","id":7974550,"avatar_url":"https://avatars.githubusercontent.com/u/7974550?v=3","gravatar_id":"","url":"https://api.github.com/users/djowen40","html_url":"https://github.com/djowen40","followers_url":"https://api.github.com/users/djowen40/followers","following_url":"https://api.github.com/users/djowen40/following{/other_user}","gists_url":"https://api.github.com/users/djowen40/gists{/gist_id}","starred_url":"https://api.github.com/users/djowen40/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/djowen40/subscriptions","organizations_url":"https://api.github.com/users/djowen40/orgs","repos_url":"https://api.github.com/users/djowen40/repos","events_url":"https://api.github.com/users/djowen40/events{/privacy}","received_events_url":"https://api.github.com/users/djowen40/received_events","type":"User","site_admin":false},"created_at":"2016-04-25T12:23:14Z","updated_at":"2016-04-25T12:23:14Z","body":"Anyone had any advances on this? I am doing exactly the same thing. \r\n\r\nMy current plan is to connect a d-type flip-flop to the direction and step outputs for the z axis with direction as the data and step as the clock. Hence latching the direction state in each time a new step is taken. \r\n\r\nIf anyone has a grbl firmware fix for this I would love to here it. It took a quick look in the code and it was quite obvious that it would take me a while to find the code responsible let alone make a change without breaking something."}}
