SOLUTION: Inconsistent Live-Z Values  

SOLUTION: Inconsistent Live-Z Values

Below is how I resolved this issue on my MINI and is also similar to how I print with my ZARIBO and old-school MK2. 

The solution is pretty simple: Always start a print under the same conditions which you calibrated it to. For example, by using this approach you can go from PLA to ABS without much z adjustment. Again, this works for me. I have been using it for years on my other machines. 

There are 2 things you must do:

1. Use a custom start g-code for every print. This g-code will move the MINDA away from the bed while it heats and before running mesh bed leveling. The greatly reduces variation in the mesh leveling due to temperature. 
   • This also allows you to adjust other parameters like esteps if you have upgraded your extruder like I have. 
   • Running the first layer calibration wizard on screen with an upgraded extruder is not representative of how my machine will actually lay down material, which brings me to the second step...
2. Go old-school and set your Live-Z using V2 Calibration.gcode. This was the method required before it was built into the firmware. As with point 1, using this gcode allows for tweaks and modifications you may be using in your printing but not reflected in the calibration wizard. 
   • V2 Calibration uses the same warmup as my start g-code and has the updated esteps I needed for my extruder. I can also tweak the temperatures if switching from one material type to another. 

A lot of words for a pretty simple solution. Always print to what you calibrated to. When you print, be consistent! This works for me. It works on my MINI and my other machines. Hope this helps anyone struggling with this issue.
