I'm sorry I made a big mistake in the first question, I meant of course to do this in Marlin because in Repetier it already works like that for delta printers, I was wondering if something similar would be possible with Marlin.

The G29 Auto_Bed_Leveling is independent from whether you are running on a Delta or not. The G28 command makes an 'identity' correction matrix (1's running down the diagonal) that it multiplies against any future coordinate it gets. The G29 command just warms over that correction matrix so it reflects what is really going on with the bed. If you turn on both Delta support and Auto_Bed_Leveling, you should have what you want.
Unfortunately, I don't have a Delta printer so I can't verify that.

ABL Help
I just built a GMax printer and the auto bed leveling is not compensating for the bed enough as it isn't the most level bed ever... I am using an MKS Base V1.4 with a BLTouch sensor and Marlin RC5 firmware. The whole process works and I can see the z-axis adjusting but it is not adjusting a significant enough amount for the nozzle to stay a consistent distance from the bed. Right now I am using the grid and 4 probe points in marlin (so 16 points recorded). Is there a way I can get the auto bed leveling to more closely follow the curvature of the bed? I am eventually going to upgrade to glass (have acrylic now) to get a more level surface but I should have to given that I have ABL and a fairly accurate sensor. Will just typing G29 V 4 into my start g-code make it work or will I need to do more?

The default is a 3x3 grid if you don't specify the number of points. So you would want G29 u4 T V4 or G29 P4 T V4 depending on where you got your code from.
You might want to try the RCBugFix file at www.github.com/MarlinFirmware/Marlin and turn on Mesh Bed Leveling. That might help you with the not flat bed.

My Auto Bed Leveling In Action
Hi Roxy,
I finally got my auto bed leveling working. Here's a video demonstrating it:

and here's the more lengthy post that includes a little more detail about the setup:

When will auto bed leveling with matrix be ready? I'll have to do some mods to my setup when that comes out.
Thank you very much for your help!!!
Mitch
