Do any of your min switches get hit during a G29?

How do you home X and Y without endstop switches?

I don't understand how this helps with multi-colour prints. I just pause the print with an M600 whenever I need to change colours.

This halloween I printed out a lot of pencil toppers to hand out. It would have saved a lot of time if I had had this code earlier, run one G29, print out all the toppers without having to G29 before...

Maybe take out one of the \n before Bed Level Correction Matrix, to get rid of that first blank line?

edit: I forgot I already took one out. Taking out the second and remaining \n gives this:

No, that was for DarkAlchemist.

So you think nobody should ever use this code?

Only if you think there's a chance this code might eventually get pulled into the fork or "official" Marlin. As it is now, if someone wants to use it, they'll copy it in as it stands. My changes were...

I've made some changes in case someone decides to add this code to Marlin, but not enable it:

case 28: //G28 Home all Axis one at a time
#ifdef ENABLE_AUTO_BED_LEVELING
#ifndef...

Now that we have this mod to save the G29 matrix for an entire print session (or longer), it is no longer necessary to add a G29 to the start gcode when slicing. However, those of us who run our...
