There are instructions on how to implement the retraction for G28 and G29. I've been using her modified version for a while and it's great. \r\n\r\nSent from my iPhone\r\n\r\n> On 16 Feb 2015, at 20:50, Kiessar <notifications@github.com> wrote:\r\n> \r\n> What I have seen so far is, that there is no code to delay the retraction or lift before retraction.\r\n> \r\n> The issue is only one in homing G28.\r\n> In G29 from my opinion you don't need to retract at all between probing(configurable?  ). But only at the end of it. \r\n> Is there any documentation about all the movement functions? Plan movement, and do blocking movement and so on?

My skills are just to low for bigger changes. And the code looks pretty untidy already I don't want to make it worse.\r\n> \r\n> —\r\n> Reply to this email directly or view it on GitHub.\r\n> \r\n"}}
