Well, I don't use repetier as a host and have none of these issues but I think someone said they tried pronterface, which is what I use, and had the same issues so I am stumped as to what is going on. As far as the timeout I have mine left at 300.

Hello guys,
I've changed G29 command and probe_pt code like Roxy explained on his first post. My glass doesn't seem to be totally flat, but (correct me if I'm wrong) the enhanced G29 should compensate for that, right? No?
When I print, the nozzle is closer to the bed on the right side, so I have less adhesion on the left and too much on the right :-/
Here are the outputted values after G29 n 4 T 4:

Any ideas?

I created one of these for myself just to help visualize things. I plugged in your probe points for this one. Thought I'd share. I've scaled things a bit proportionately so you can see things better:

Hope that helps!

Thank you Tyson, that helped a lot!!!
Your "plot" showed me that I had the wrong origin point, it should be ORIGIN_BACK_LEFT instead of ORIGIN_FRONT_LEFT.
I did some tweaks and I think I'm getting somewhere.

Hi Tyson,
This is a lot more meaningful to me than rows of numbers. Is it created with commercial software or something that you're able to share please? I'll be very grateful as I tried to plot the probes in Excel which is the only software which I have that can remotely produce a visual plot but I eventually gave up.

Any plans to submit this to Marlin baseline?
I'll have to hunt down some information from another thread... But the fix for this might be known.
A number of bugs have been fixed in the main line Marlin code base. We need to get the better G29 merged into that. Probably a lot of these issues go away. Alternatively, we need to change this thread so it is making changes to the current code base.
Tyson: How did you do this? Can you start a thread and document what you did? This is very nice! It would be nice if this could be automatically done by the firmware!
