Good... It's Alive!
Here is one idea... At each stage, as the code base evolves towards what you want.... It might be a good idea to save an entire copy of the Marlin directory with some notes about where in that process the file set is. That way, if we need to back up a step or two, we can do it easily.
How does the nozzle retraction look? Is it leaving the nozzle in a good place when it finishes the G28 and G29?
Okay, I turned the fans on and I will call the V1. The z moves up after homing about 10mm. I will run a g29 now.
It all works as intended, but of course with raising the z we overcome the issue I had, by just lifting z. This is something I did not have to do, but I guess I can live with it.
It's a shame that we cannot prevent the z stop to trigger x&y too after g29.
It saves the matrix to eeprom.....that is fantastic!! For some reason my offset nozzle/sensor is not right anymore??? But I can adjust that easily.
I cannot adjust the nozzel / sensor offset for some reason. Any suggestions?
Figured it out...
Roxy thanks so much for all your help it works great.
How can I change the behavior of the z axis. I would like to remove the pauses it makes during g28 and g29?
Right! Save each version! :) If something goes sour, we want to be able to back track.Quote:

If you issue a M851 code you can adjust your nozzle's Z_PROBE_OFFSET without rebuilding the firmware and loading and going to default settings and saving them....
I suspect the pause you are seeing between the G28 and G29 is Marlin waiting for the nozzle to heat all the way up. If you preheat your nozzle, I bet the time delay shrinks. And once your LCD Panel is going, it may not be there either. I don't know.Quote:

Did your print work well enough for us to move on to getting your LCD panel going?
Roxy, I am struggling with the z offset. After abl, without homing I move to the center of the bed and get an M114, I get 3.13mm then I lower z to zero and get a good distance. But when now homing, the z moves upQuote:

I think the pauses in the g28 and g29 are a few mms to allow the servo to move the probe when equipped.
